Description

Technical Field

[0001] This utility model belongs to the field of brake cylinder body processing technology, and specifically relates to a brake cylinder body processing device. Background Technology

[0002] The machining of brake cylinder blocks requires high-precision and high-efficiency production processes. Fixtures are commonly used machining devices when machining brake cylinder blocks.

[0003] In existing technologies, conventional machine tools are often used for multiple processing steps. However, due to the shape limitations of the brake cylinder body, the brake cylinder body suffers from poor stability during machining after being fixed by the fixture, resulting in low processing efficiency and poor accuracy. Therefore, a fixture capable of precise positioning and improved production efficiency is needed.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide a brake cylinder body processing device, which can solve the problem that the clamp cannot stably hold the brake cylinder body, resulting in poor stability of the cylinder body during processing, and thus low processing efficiency and poor precision of the brake cylinder body.

[0006] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0007] A brake cylinder body machining apparatus, comprising:

[0008] The processing device body includes an operating table. A pair of fixed plates are fixedly connected to the operating table. Movable plates are movably mounted on one side of each of the opposite sidewalls of the fixed plates, allowing the movable plates to move relative to the fixed plates. This facilitates adjustment of the distance between the movable plates, enabling the fixation of the left and right sides of the brake cylinder. A fixed clamping plate is fixedly connected to the bottom of each movable plate, and a movable clamping plate is movably mounted on the top of each movable plate. The fixed and movable clamping plates are installed in a corresponding manner. Through the cooperation of the fixed and movable clamping plates, the upper and lower ends of the brake cylinder can be clamped and fixed. Simultaneously, the movable clamping plate allows for adjustment of the distance between the fixed and movable clamping plates.

[0009] The pin positioning mechanism includes a slider. The slider is slidably connected to both the fixed and movable clamping plates, and a positioning pin is mounted through the slider. The positioning pin connects to the positioning hole of the brake cylinder. After the clamping device fixes the brake cylinder, connecting the positioning pin to the positioning hole further secures the cylinder, ensuring it will not move and thus ensuring stability during machining. This improves machining efficiency and precision. Furthermore, because the slider can move between the fixed and movable clamping plates, it allows for position adjustment of the positioning pin, facilitating its installation into the positioning hole on the cylinder.

[0010] In one or more embodiments of this utility model, a socket hole is provided on the side wall of each pair of fixed plates, and a positioning rod is sleeved through the socket hole, so that the positioning rod can move and rotate on the fixed plate.

[0011] In one or more embodiments of this utility model, one end of the positioning rod is fixedly connected to the side wall of the movable plate. When the positioning rod moves on the fixed plate, it can drive the movable plate to move, thereby adjusting the distance between the two movable plates. Simultaneously, the rotatable portion of the positioning rod mounted on the fixed plate can drive the movable plate to rotate, allowing the brake cylinder, after being fixed by the fixture, to rotate according to processing requirements and adjust the processing angle. The other end of the positioning rod is equipped with a pin, which drives the positioning rod to rotate.

[0012] In one or more embodiments of this utility model, a limiting hole is provided on the fixing plate, and a fixing rod is slidably inserted into the limiting hole.

[0013] In one or more embodiments of this utility model, the movable plate is provided with multiple limiting screw holes at equal intervals around the positioning rod. One end of the fixing rod is threaded into the corresponding limiting screw hole. By inserting the fixing rod into the fixed plate and the movable plate through the limiting holes and the limiting screw holes, the relative rotation between the fixed plate and the movable plate can be restricted by the fixing rod, so that the movable plate after angle adjustment is easy to fix, thereby ensuring the stability during cylinder processing.

[0014] In one or more embodiments of this utility model, an adjusting screw is threaded through the movable clamp plate, so that the movable clamp plate can be moved by rotating the adjusting screw. The movable clamp plate has a pair of mounting holes on both sides of the adjusting screw.

[0015] In one or more embodiments of this utility model, a limit rod is slidably installed in each of the pair of mounting holes, and a limit block is fixedly connected to the upper end of both the adjusting screw and the limit rod.

[0016] In one or more embodiments of this utility model, a bearing is installed on the top of the movable plate, the lower end of the adjusting screw is installed inside the bearing, and the lower end of the limiting rod is fixedly connected to the top of the movable plate. By rotating the adjusting screw, the movable clamping plate can be moved up and down, thereby adjusting the distance between the fixed clamping plate and the movable clamping plate. At the same time, when the movable clamping plate moves up and down, it slides on a pair of limiting rods, which stabilize the up and down movement of the mounting hole.

[0017] In one or more embodiments of this utility model, the positioning pin is set as a lead screw, and the positioning pin is threaded to the slider in a through manner. Thus, by rotating the positioning pin, the positioning pin can be moved on the slider, and the positioning pin can be inserted into the positioning hole on the cylinder body to fix the cylinder body.

[0018] In one or more embodiments of this utility model, both the fixed clamping plate and the movable clamping plate are provided with sliding grooves, and the slider is slidably connected to the corresponding sliding groove, so that the slider can move up and down within the fixed clamping plate and the movable clamping plate through the sliding groove.

[0019] Compared with the prior art, this utility model is equipped with an adjustable movable plate and a movable clamping plate, which allows for simultaneous clamping and fixing of the left and right sides and the top and bottom sides of the brake cylinder, improving the stability of clamping the brake cylinder. In addition, a pin positioning mechanism is provided, which ensures that the cylinder will not move during processing by cooperating with the positioning pin and the positioning hole on the cylinder, thereby improving the processing efficiency and accuracy of the cylinder.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0029] like Figures 1-3 As shown, a brake cylinder processing device according to one embodiment of the present invention includes a processing device body 1 and a pin positioning mechanism 2.

[0030] like Figures 1-3 As shown, the processing device body 1 includes an operating table 11. A pair of fixed plates 12 are fixedly connected to the operating table 11. Movable plates 13 are movably installed on one side of the opposite sidewall of the pair of fixed plates 12, allowing the movable plates 13 to move relative to the fixed plates 12. This makes the distance between the pair of movable plates 13 easy to adjust, thereby fixing the left and right sides of the brake cylinder. A fixed clamping plate 14 is fixedly connected to the bottom of the movable plate 13, and a movable clamping plate 15 is installed on the top of the movable plate 13 in a vertically movable manner. The fixed clamping plate 14 and the movable clamping plate 15 are installed in a corresponding manner. Through the cooperation of the fixed clamping plate 14 and the movable clamping plate 15, the upper and lower ends of the brake cylinder can be clamped and fixed. At the same time, the movable clamping plate 15 allows the distance between the fixed clamping plate 14 and the movable clamping plate 15 to be adjusted.

[0031] Preferably, the brake cylinder is fixed on its upper, lower, left, and right sides by a pair of movable plates 13, and on its upper and lower sides by a fixed clamping plate 14 and a movable clamping plate 15. This allows for synchronous fixation of the brake cylinder on its left, right, upper, and lower sides, greatly improving the stability of the clamp after holding the brake cylinder. Furthermore, since the spacing between the pair of movable plates 13 and the spacing between the movable clamping plate 15 and the fixed clamping plate 14 are adjustable, the clamp can hold and fix brake cylinders of different sizes and shapes, improving the practicality of the device.

[0032] like Figure 3 As shown, each of the two fixed plates 12 has a socket hole 17 on its side wall. A positioning rod 16 is sleeved through the socket hole 17, allowing the positioning rod 16 to move and rotate on the fixed plate 12.

[0033] like Figure 3 As shown, one end of the positioning rod 16 is fixedly connected to the side wall of the movable plate 13. When the positioning rod 16 moves on the fixed plate 12, it can drive the movable plate 13 to move, thereby adjusting the distance between the two movable plates 13. At the same time, the rotatable positioning rod 16 mounted on the fixed plate 12 can drive the movable plate 13 to rotate, so that the brake cylinder body, after being fixed by the fixture, can rotate according to the processing requirements, thereby adjusting the processing angle. The other end of the positioning rod 16 is equipped with a pin 18, which drives the positioning rod 16 to rotate.

[0034] like Figure 3 As shown, a pair of fixed plates 12 are threadedly connected to the side walls of each fixed plate 12 in a through manner. One end of the limiting screw 116 abuts against the side wall of the movable plate 13. Thus, the abutment of the movable plate 13 by the limiting screw 116 ensures that the pair of movable plates 13 will not move left or right after clamping and fixing the brake cylinder body, thus ensuring stability during processing.

[0035] like Figure 3 As shown, a limiting hole 110 is provided on the fixing plate 12, and a fixing rod 19 is slidably inserted into the limiting hole 110.

[0036] like Figure 3 and Figure 5 As shown, multiple limiting screw holes 111 are equally spaced on the movable plate 13 with the positioning rod 16 as the center. One end of the fixing rod 19 is threaded into the corresponding limiting screw hole 111. The fixing rod 19 is inserted into the fixed plate 12 and the movable plate 13 through the limiting hole 110 and the limiting screw hole 111. The relative rotation between the fixed plate 12 and the movable plate 13 can be restricted by the fixing rod 19, so that the movable plate 13 after angle adjustment can be easily fixed, thereby ensuring the stability during cylinder processing.

[0037] like Figure 2 , Figure 3 and Figure 5 As shown, an adjusting screw 112 is threaded through the movable clamping plate 15, so that the movable clamping plate can be moved by rotating the adjusting screw 112. A pair of mounting holes 115 are provided on both sides of the adjusting screw 112.

[0038] like Figure 3 and Figure 5 As shown, a limit rod 114 is slidably installed in a pair of mounting holes 115, and a limit block is fixedly connected to the upper end of the adjusting screw 112 and the limit rod 114.

[0039] like Figure 3 and Figure 5 As shown, a bearing 113 is installed on the top of the movable plate 13, the lower end of the adjusting screw 112 is installed inside the bearing 113, and the lower end of the limiting rod 114 is fixedly connected to the top of the movable plate 13. By rotating the adjusting screw 112, the movable clamping plate 15 can be moved up and down, thereby adjusting the distance between the fixed clamping plate 14 and the movable clamping plate 15. At the same time, when the movable clamping plate 15 moves up and down, it slides on a pair of limiting rods 114, which stabilize the up and down movement of the mounting hole 115.

[0040] like Figures 1-4 As shown, the pin positioning mechanism 2 includes a slider 21. The slider 21 is slidably connected to both the fixed clamping plate 14 and the movable clamping plate 15. A positioning pin 22 is installed through the slider 21. The positioning pin 22 connects to the positioning hole of the brake cylinder. After the clamp fixes the brake cylinder, connecting the positioning pin 22 to the positioning hole of the brake cylinder further secures the cylinder, ensuring that the cylinder will not move after being fixed by the clamp, thus ensuring stability during cylinder machining and improving machining efficiency and accuracy. Simultaneously, because the slider 21 can move on the fixed clamping plate 14 and the movable clamping plate 15, the slider 21 can adjust the position of the positioning pin 22, facilitating its installation into the positioning hole on the cylinder.

[0041] like Figure 2 and Figure 3 As shown, the positioning pin 22 is set as a lead screw, and the positioning pin 22 is threaded to the slider 21 in a through manner. Thus, by rotating the positioning pin 22, the positioning pin 22 can be moved on the slider 21, and the positioning pin 22 can be inserted into the positioning hole on the cylinder body to fix the cylinder body.

[0042] like Figure 2 Combination Figure 4As shown, both the fixed clamping plate 14 and the movable clamping plate 15 are provided with sliding grooves 23. The slider 21 is slidably connected in the corresponding sliding groove 23, and the slider 21 can move up and down in the fixed clamping plate 14 and the movable clamping plate 15 through the sliding groove 23.

[0043] In use, the brake cylinder is placed on the fixed clamping plate 14. By rotating the limiting screw 116, the limiting screw 116 abuts against the side wall of the movable plate 13. The pair of movable plates 13 can clamp and fix the left and right sides of the brake cylinder. Then, by sliding the slider 21, the positioning pin 22 on the fixed clamping plate 14 aligns with the positioning hole on the cylinder. By rotating the positioning pin 22, the positioning pin 22 is inserted into the positioning hole, so that the positioning pin 22 limits the cylinder. Then, by rotating the adjusting screw 112, the movable clamping plate 15 abuts against the cylinder, and the brake cylinder can be moved through the fixed clamping plate 14 and the movable clamping plate 15. The upper and lower sides of the cylinder are clamped and fixed together. At the same time, the positioning pin 22 on the movable clamping plate 15 is inserted into the positioning hole on the cylinder to complete the fixation of the cylinder. When the cylinder needs to be adjusted by rotation during machining, the fixing rod 19 is pulled out and the limiting screw 116 is loosened. The positioning rod 16 is rotated to drive the movable plate 13 to rotate, so as to drive the cylinder to rotate. When the cylinder is rotated to the required machining angle, the fixing rod 19 is inserted into the fixing plate 12 and the movable plate 13 to restrict the relative rotation between the two. At the same time, the limiting screw 116 is tightened so that the movable plate 13 can stably clamp the cylinder.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
