Universal vertical-boring machine 2135 is adapted to perform a certain number of procedures. These include drilling, reaming and others. Most often, this unit was delivered to those enterprises that are engaged in small-scale production of parts.
Device design
In many respects, the good technical characteristics of the 2N135 vertical drilling machine were achieved due to the fact that it has a rather successful design. It consists of the following parts:
- To fix the working tool, a working head is used;
- for processing working parts there is an oil pump;
- system for cooling the working area;
- the power supply of the machine is due to the presence of an electrical system, which includes an electrical cabinet;
- as supporting devices used column, table, stove.
The technical characteristics of the vertical drilling machine 2H135 indicate that the object is quite versatile. In many respects this is facilitated by the fact that on such a device it is really possible to work with billets of the most diverse alloys. In addition, the dimensions of the products can vary in a fairly large interval. The ability to work with a wide variety of workpieces became possible due to the fact that high-speed alloys and steels are used as cutting tools. All these materials are characterized by a high rate of strength.
Ease of use
On this unit there is a gearbox, as well as a spindle, by adjusting the rotation speed of which you get the opportunity to select the processing mode. Thanks to this, it is possible to obtain holes with a wide variety of characteristics, as well as in various materials. It is also worth noting that the technical characteristics of the vertical drilling machine 2H135 allow it, for example, to thread, if you use a machine tap for this . Such a procedure was made possible due to the fact that the spindle is able to rotate in both directions. In other words, the special design and the presence of a reversing system further expand the range of use of the unit.
Machine Features
The following technical data can be distinguished from a vertical-drilling machine of this model, which are associated with the features of its design:
- There is a distance of 300 mm between the axis of the vertical spindle and the guide.
- Using this machine, you can get a hole with a maximum diameter of 35 mm.
- The maximum torque that the spindle can develop reaches 400 Nm. The rotational speed of the device is in the range of 31.5-1400 rpm. There are 12 rotational speeds in this range.
- The dimensions of the base for operation for this device are 400x500 mm. The table can be moved vertically by 300 mm.
- This unit is able to develop a force when applying 15 kN. In order to adjust the degree of feed of the spindle, there are 9 steps.
- The total dimensions of this machine are 2535x825x1030 mm.
- The design has an engine that is responsible for the main feed. Its maximum power is 4 kW.
- Coolant is supplied to the working area. In order to supply this substance to the desired location, an electric pump is provided in the design.
Arrangement of elements
The machine 2H135 has a main bearing element, which is made in the form of a column. This element is made of cast iron. Due to the presence of a large number of elements, and also due to the fact that they are made of metal alloys, such a characteristic of a vertical drilling machine 2H135, as a weight, is quite high. The mass of this device reaches 1.2 tons. The work table and drill head can be moved. For this, the machine has a manual drive, which is installed along the supporting column. Another feature is that the base plate is made with an internal cavity. It is used to place a sump there, as well as a container with coolant. A pump is installed on the top surface of the stove, which pumps liquid to cool the working area.
Transmission. Spindle
The most important element in the design of this machine is the gearbox. It is capable of reporting up to 12 different rotational speeds to the spindle. This is very important, since the success of the work depends on the spindle speed of the vertical drilling machine 2H135. The spindle is located in the upper part of the unit, under the electric motor, which is mounted vertically.
In order to change the rotation speed of this device, there are different mobile units in the speed box. They are an assembly of gears, each of which has its own parameters. The connection of this element with an electric motor is also carried out by means of a gear transmission and an elastic coupling. The plunger oil pump in this device is responsible for the timely lubrication of all elements.
The feed mechanism of the machine 2N135
The feed mechanism is the most important working element for a vertical drilling machine 2H135. Repair of this element is quite complicated, and therefore it is necessary to monitor its condition very carefully. The presence of this structural element allows the unit to perform such technical operations:
- manual feed advance;
- threading the workpiece using manual feed;
- in manual mode, you can bring the workpiece to the processing mechanism;
- turning on and off the feed;
- lead the spindle up from the product.
The element itself has a rather complicated design, but at the same time the essence of its work remains very simple and understandable. The device has a steering wheel that starts to rotate and transmits this rotation to the cam-type coupling. This part is connected to the pinion shaft using a different type of coupling. This shaft is connected to the spindle element - a rail. The rail is necessary in order to ensure vertical movement of the part.
Safety precautions. Before and during machine operation
Since this unit is dangerous for the worker, there is a manual for the 2N135 drilling machine, in which safety rules are prescribed:
- It is important enough to monitor workwear. Cuffs of sleeves should be buttoned. Hair should be removed under a beret or headscarf. If this is a scarf, then it should be tied so that there are no hanging ends. Safety glasses should be worn.
- The machine is tested for idle operation. It is important to check all fences and their performance.
- The worker, as well as the auxiliary tool, should be inspected for whether they are working or not.
- It is necessary to check the operability of the protective element.
There are also rules that must be observed during operation:
- The milling cutter and the workpiece must be firmly fixed.
- You can not put anything on the machine, as well as lean on it.
- During work, it is forbidden to be distracted by extraneous conversations and so on.
- The belt, milling cutter and other working parts of the machine must not be missed.
- Do not leave the device unless it has previously been stopped.
Passport of vertical drilling machine 2135
This document is an instruction manual for industrial equipment. The document contains information that is necessary for both the maintenance staff and the employee. It also lists the safety requirements that must be observed during an emergency.
For example, if a person was injured by electric shock, then the following actions must be carried out:
- the victim should be freed from the action of current, and the machine should be disconnected from electricity using a tool with an insulated handle;
- during the release of the victim from the current, he must not be touched with his bare hands;
- the incident must be immediately reported to the administration, and if the victim lost consciousness, then artificial respiration should be done.
So, we examined the technical characteristics of the vertical drilling machine 2H135.
