Description

Technical Field

[0001] The utility model relates to the technical field of railway vehicle equipment processing, in particular to a process equipment for turning the end face of an upper valve body. Background Art

[0002] When a railway vehicle is parked on a line, it may slip due to gravity and other external forces such as wind, vibration, and collision. In addition, if a moving vehicle loses control due to potential energy and inertia, it will accelerate and may cause serious safety accidents. Effective anti-slip measures must be taken for parked vehicles to ensure the safety of the line and vehicles. The vehicle automatic anti-slip device is a key component of the C80 aluminum vehicle parking brake system and is tightly connected to the brake part of the brake cylinder. Its main function is to automatically lock the retraction of the brake cylinder piston rod and generate the necessary braking force by acting on the basic brake device, thereby achieving the anti-slip function and ensuring the safety of the vehicle.

[0003] The upper valve body is a crucial component in the anti-skid device. As a cast, special-shaped part with a large length, it is difficult to align and align. The manufacturing quality of the upper valve body is directly related to the safe use of the vehicle. If the processing quality of the upper valve body does not meet the standards, it will directly affect the assembly performance and braking effect of the vehicle's automatic anti-skid device, thereby threatening the safety of the vehicle and the line.

[0004] At present, when processing the valve body of the anti-slip device, the alignment of the stoppers on the left and right end faces is a difficult point. The traditional boring method of the machining center is very difficult for clamping and alignment due to the irregular size of the casting workpiece material and the large length dimension. The auxiliary clamping time is long and the production efficiency is low. What is more serious is that this processing method is difficult to guarantee product quality and may lead to the production of unqualified products, which in turn causes greater economic losses and safety hazards.

[0028] like Figure 1-3 As shown, the present invention provides a process equipment for turning the end face of an upper valve body, comprising: a positioning column 17, two vertical plates 13 and a chuck support 15;

[0029] The vertical plate 13 is a rectangular structure. The two vertical plates 13 include a first vertical plate and a second vertical plate. The first vertical plate and the second vertical plate are installed on the chuck holder 15 in a transverse symmetrical manner. The two vertical plates 13 are arranged vertically with the chuck holder 15. The two vertical plates 13 are fixedly connected to the chuck holder 15 by a number of M16 hexagon socket head screws 31. The upper end surface of the vertical plate 13 is provided with a through hole. The through hole of the first vertical plate is provided with a first clamping bolt 18. The through hole of the second vertical plate is provided with a third clamping bolt 2. The inner wall of the through hole provided on the upper end surface of the vertical plate 13 is provided with a thread. The clamping bolt 18 and the third clamping bolt 2 can rotate along the threaded inner wall of the vertical plate 13. The first vertical plate is provided at the upper end, and the second vertical plate is provided at the lower end. The first clamping bolt 18 and the third clamping bolt 2 are installed relative to each other.

[0030] The chuck holder 15 is a cylindrical structure, and a positioning column 17 is provided at the center of the chuck holder 15. The positioning column 17 is a cylindrical structure and is fixedly connected to the chuck holder 15 by a number of M10 hexagon socket head screws 32. An adjustment pad 16 is provided on the positioning column 17. The adjustment pad 16 is a circular ring structure and is sleeved on the outer wall of the positioning column 17. A first reinforcing plate 12 and a second reinforcing plate 14 are respectively provided on both sides of the first vertical plate and the second vertical plate. The first reinforcing plate 12 and the second reinforcing plate 14 are respectively fixedly connected to the first vertical plate and the second vertical plate by a number of bolts. The first reinforcing plate 12, the second reinforcing plate 14, the first vertical plate and the second vertical plate form a square box structure;

[0031] A third clamping block 21 is provided at the upper end of the second vertical plate, and the third clamping bolt 2 passes through the second vertical plate and is connected to the third clamping block 21. By rotating the third clamping bolt 2, the longitudinal movement of the third clamping block 21 can be controlled. A second clamping block 11 is provided on one side of the first reinforcing plate 12, and a second clamping bolt 19 is provided on the second clamping block 11. The upper valve body end face turning process equipment also includes a first clamping block 1, and the first clamping block 1 is an L-shaped structure. The inner wall of one side of the first clamping block 1 is provided with a cylindrical structure with an outer edge. The cylindrical structure in the first clamping block 1 matches the groove provided on the outer wall structure of the upper valve body, and the first clamping block is used to limit the upper valve body;

[0032] In the upper valve body end face turning process equipment, the positioning column 17 is used to install the upper valve body and perform preliminary positioning of the upper valve body. The adjustment pad 16 sleeved on the outer wall of the positioning column 17 is used to adjust the installation position of the upper valve body on the positioning column 17. By changing the number of the adjustment pads 16, the axial position of the upper valve body can be adjusted. After ensuring that the end face of the upper valve body is tightly against the upper valve body, the first clamping block 1 is inserted into the upper valve body.

[0033] The first clamping bolt 18 and the third clamping bolt 2 are used to longitudinally position the upper valve body on the positioning column 17 after the upper valve body is initially positioned. By driving the first clamping bolt 18 and the third clamping bolt 2, the third clamping block 21 provided on the first clamping bolt 18 and the third clamping bolt 2 longitudinally clamps the upper valve body.

[0034] The second clamping block 11 is inserted from the side of the upper valve body to position the upper valve body. The upper valve body that has been longitudinally positioned is axially clamped by rotating the third clamping bolt 2 provided on the second clamping block 11 .

[0035] The upper valve body end face turning process equipment can effectively fix the upper valve body through a multi-point, multi-directional clamping and positioning mechanism to prevent any unnecessary movement during the processing, thereby ensuring the stability of the processing. The design of the adjustment pad 16 allows fine-tuning of the axial position of the upper valve body to ensure that it can meet the required accuracy requirements during processing. The clamping and release of the upper valve body can be achieved by simply turning the bolts, which is easy and efficient to operate.
