Description

Technical Field

[0001] This utility model belongs to the technical field of drilling processing equipment, specifically relating to a planar drilling processing device for the support base of a train brake cylinder. Background Technology

[0002] The support base of a train brake cylinder is a crucial component of the train braking system. It provides a stable mounting position for the brake cylinder, preventing it from wobbling or shifting. It is typically made of high-strength metal materials, such as cast steel or alloy steel, to meet the requirements for load-bearing and force transmission. The shape of the support base varies; a common shape is a cuboid base with drilled mounting holes for securing it to the train brake cylinder and the train car body frame with bolts. One drilling device used for drilling the support base is a radial drilling machine. The main structure of a radial drilling machine includes a base, column, radial arm, spindle, and drilling tool box. Its principle is that the motor drives the spindle to rotate the drill bit. Through manual or automatic feed, the drill bit cuts vertically into the workpiece (feed motion), achieving the purpose of planar drilling. When a radial drilling machine is in use, the drill bit drills a hole on the surface of the workpiece. During the drilling process, debris may be generated and fly around. This debris may land on the outer surface of the column, as may dust in the air, causing impurities to adhere to the column surface and leading to wear. This can cause difficulty in raising or lowering the radial arm or jamming. Manual lubrication is usually required, but the intervals for manual lubrication are often long, and sometimes the column may already be worn when lubrication is needed. Radial drilling machines do not have an automatic lubrication design for the column surface, which is a shortcoming.

[0003] Existing radial drilling machines lack an automatic lubrication design for adding lubricating oil to the column surface during use. To address this issue, this application proposes a planar drilling device for the support base of a train brake cylinder. Utility Model Content

[0017] Please see Figures 1 to 7 This utility model provides a technical solution: a planar drilling processing device for a support base of a train brake cylinder, comprising a planar drilling processing mechanism for processing the support base of the train brake cylinder, including a base 11 and a column 12 fixedly connected, a lifting rocker arm 13 mounted on the column 12, a planar drilling tool holder 14 mounted on the lifting rocker arm 13, and a working support 15 fixed to the base 11 by bolts, such as... Figure 1As shown, A is the brake cylinder support base. The support base A is fixed to the work stand 15 by a conventional screw-type clamp. The flat drilling tool holder 14 is the spindle box. Driven by the motor, the tool installed on the flat drilling tool holder 14 rotates, which can perform flat drilling on the support base A. The machining principle of the radial drilling machine is existing technology and will not be described in detail in this application. The vibration component includes a fixed sleeve 2 fixed to the lifting rocker arm 13 by screws, a vibration plate 4 inserted into the fixed sleeve 2 at one end, a pin 5 penetrating the end of the vibration plate 4, and a vibration spring 6 installed between the opposing pins 5.

When drilling the support base A, the entire drilling machine generates vibration force at a microscopic level invisible to the naked eye. The vibration component is subjected to the vibration force, and the vibration spring 6 is subjected to the vibration force. The vibration spring 6 and the vibration plate 4 are vertically The vibration plate 4 transmits the vibration force to the vibration ring 10. The vibration ring 10, which is installed inside the fixed sleeve 2 and fixedly connected to one end of the vibration plate 4, has a compression half-ring 102 welded to its surface. The vibration ring 10 is subjected to the vibration force of the vibration plate 4 and vibrates at a micro level.

The lubrication assembly includes a sealing ring 3 connected to the fixed sleeve 2, a pressing ring 8 fixedly connected to the sealing ring 3, and an oil-impregnated cotton pad 9 installed on the outside of the pressing ring 8. The oil-impregnated cotton pad 9 is impregnated with lubricating oil. Under the action of the vibration force of the vibration ring 10 and the compression half-ring 102, the lubricating oil impregnated on the vibrating oil-impregnated cotton pad 9 seeps out. The seeping lubricating oil passes through the pressing ring 8 and comes into contact with the surface of the column 12. It has the function of automatically adding lubricating oil and lubricating the surface of the column 12.

[0018] In this embodiment, the insert 5 is a stepped columnar structure with a wide diameter in the middle and narrow diameters at both ends. One end of the insert 5 passes through the vibration plate 4 and the other end defines the vibration spring 6. One end of the vibration plate 4 has a circular hole for the insert 5 to pass through. One end of the vibration spring 6 is sleeved on the outside of the insert 5. The outer surface of the fixing sleeve 2 has a through hole for the vibration plate 4 to pass through.

The orthographic projection of the oil-soaked cotton pad 9 is a semi-circular shape. Under the vibration force of the vibrating circular ring 10 and the compression half-ring 102, the lubricating oil on the vibrating oil-soaked cotton pad 9 seeps out. The seeping lubricating oil passes through the fastening ring 8 and comes into contact with the surface of the column 12, thus having the function of automatically adding lubricating oil and lubricating the surface of the column 12.

[0021] In this embodiment, the distance between the vibrating ring 10 and the fixed sleeve 2 and the rubber ring a of the fastening ring 8 is 2 mm. The vibrating ring 10 is suspended inside the fixed sleeve 2, which is beneficial for the vibration of the vibrating ring 10.

[0022] In this embodiment, a stabilizing round rod 71 is fixed to the outer surface of both the fixing sleeve 2 and the sealing ring 3.

The vibration component is subjected to the vibration force, the vibration spring 6 is subjected to the vibration force, the vibration spring 6 and the vibration plate 4 vibrate in the vertical direction, and the vibration plate 4 transmits the vibration force to the vibration ring 10. The vibrating ring 10 is suspended inside the fixed sleeve 2, and the vibrating ring 10 and the extrusion half ring 102 vibrate. Under the vibration force of the vibrating ring 10 and the extruding half ring 102, the lubricating oil on the vibrating oil-soaked cotton pad 9 seeps out. The seeping lubricating oil passes through the tight-fitting ring 8 and comes into contact with the surface of the column 12, thus having the function of automatically adding lubricating oil and lubricating the surface of the column 12. When the fixed sleeve 2 and the sealing ring 3 are combined, the binding rope ring 72 is sleeved on the outside of the stable round rod 71, so that the fixed sleeve 2 and the sealing ring 3 are combined stably. The fixed sleeve 2 and the sealing ring 3 are separate structures, which makes it easy to disassemble the sealing ring 3 and replace the oil-impregnated cotton pad 9.
