Description

Technical Field

[0001] This utility model relates to the field of track plate processing fixtures, and in particular to a fixture for processing track plates. Background Technology

[0002] Track shoes are key running gear components of tracked vehicles. Drilling holes in the track shoes is one of the critical processes in track shoe manufacturing. By machining connecting holes in the track shoes, a reliable connection base is provided for subsequent assembly. To ensure the stability and processing quality of the track shoes during the drilling process, clamps are usually used to fix them in place.

[0003] According to the Chinese patent "Clamping Fixture for Track Plate Processing" (authorization announcement number CN220839835U), this application uses a pressure plate and a limiting plate to press the top of the track plate; uses a stop screw to press the front and rear sides of the track plate; and uses a squeezing screw and left and right upright plates to press and limit the left and right sides of the track plate, thereby maximizing the stability of the clamping and providing an effective guarantee for the quality of boring.

[0004] Although the aforementioned application uses a pressure plate and a limiting plate to limit the track plate from the top, the track plates in the prior art are usually provided with raised reinforcing ribs. When the pressure plate is used to limit the track plate from the top, the pressure plate will only contact the top of the raised reinforcing ribs, resulting in a small contact area, which affects the stability when the track is clamped. Utility Model Content

[0005] Therefore, it is necessary to provide a jig for processing track plates to address the problem that when using a pressure plate to limit movement from the top, the pressure plate only contacts the top of the protruding reinforcing rib, resulting in a small contact area and thus affecting the stability during clamping.

[0006] Includes: a processing table; a fixing mechanism, the fixing mechanism including a limiting plate fixedly connected to the processing table and a first hydraulic cylinder, the telescopic end of the first hydraulic cylinder being fixedly connected to a fixing plate, and a reinforcing component being provided on one side of the limiting plate; The reinforcement assembly includes two connecting rods and two abutment plates. The top end of the abutment plate is fixedly connected to the bottom end of the connecting rod. A second hydraulic cylinder is fixedly connected to one side of the top end of the limiting plate. The top end of one of the connecting rods is installed with the telescopic end of the second hydraulic cylinder. A groove is provided at the bottom end of the abutment plate. A horizontal plate is slidably connected to the opposite sides of the two abutment plates. Two pressure plates are fixedly connected between the opposite sides of the two horizontal plates.

[0007] In one embodiment, the reinforcement assembly further includes two cylinders respectively fixedly connected to opposite sides of the two abutment plates. A circular rod is slidably connected to the inner wall of each cylinder. The bottom end of the circular rod is fixedly connected to the top end of the horizontal plate, and a spring is fixedly connected between the top end of the circular rod and the inner top wall of the cylinder. This facilitates the simultaneous pressing of the top end of the track plate by the horizontal plate and the pressure plate after the abutment plates have pressed and fixed the reinforcing ribs on the track plate. After pressing, the spring helps to compress the horizontal plate and the pressure plate with a certain amount of resistance.

[0008] In one embodiment, mounting blocks are fixedly connected to opposite sides of the two abutment plates. A threaded rod is threaded onto the inner wall of each mounting block. A fixing block is fixedly connected to the top of the cross plate, and a threaded hole is provided at the top of the fixing block. This facilitates fixing the position of the pressure plate after it has abutted the top of the track plate, making the pressure plate and the abutment plates a single unit.

[0009] In one embodiment, a limiting rod is fixedly connected to one side of the connecting rod, and the surface of the limiting rod at the end away from the connecting rod is slidably connected to the inner wall of the limiting plate. This facilitates limiting the movement path of the connecting rod.

[0010] In one embodiment, contact pads, which are rubber components, are fixedly connected to the inner wall of the groove, the bottom end of the cross plate, and the bottom end of the pressure plate. This increases the friction between the track plate and the track plate during the process of fixing the track plate by the clamping plate, cross plate, and pressure plate.

[0011] In one embodiment, the center of the threaded rod and the center of the threaded hole in the fixing block are on the same axis, and the diameter of the threaded hole matches the diameter of the threaded rod. This ensures the stability of the connection between the threaded rod and the threaded hole.

[0012] In one embodiment, the bottom end of the cross plate and the bottom end of the pressure plate are located on the same horizontal plane. This facilitates simultaneous contact with the surface of the track plate during the fixing process.

[0013] In one embodiment, the top end of one of the connecting rods is fixedly installed to the telescopic end of the second hydraulic cylinder by bolts and nuts. This facilitates the replacement of the abutment plate, cross plate, and pressure plate when wear occurs. Beneficial effects

[0014] 1. The above-mentioned fixing mechanism uses a limiting plate and a fixing plate to initially fix the position of the track plate. Under the action of the reinforcing components, the two clamping plates help to clamp and fix the reinforcing ribs on the track plate. At the same time as clamping and fixing, it helps the cross plate and pressure plate to contact the surface of the track plate and clamp the track plate. Under the action of the clamping plate, cross plate and pressure plate, it helps to better fit the surface of the track plate during the fixing process, increasing the contact area during fixing, thereby enhancing the stability of fixing the track plate. 2. In this solution, the mounting block, threaded rod, fixing block and corresponding threaded hole help to fix the position of the pressure plate after the pressure plate is pressed against the top of the track plate, so that the pressure plate and the pressing plate form an integral part, thereby ensuring the stability of the cross plate and pressure plate during the fixing of the track plate.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, 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, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined with Figures 1-5 This invention describes a jig for machining track plates.

[0020] In one embodiment, a jig for processing track plates includes: a processing table 100; a fixing mechanism 200, the fixing mechanism 200 including a limiting plate 210 fixedly connected to the processing table 100 and a first hydraulic cylinder 220, the telescopic end of the first hydraulic cylinder 220 being fixedly connected to a fixing plate 230, and a reinforcing component 240 being provided on one side of the limiting plate 210. The reinforcement component 240 includes two connecting rods 241 and two abutment plates 242. The top end of the abutment plate 242 is fixedly connected to the bottom end of the connecting rod 241. A second hydraulic cylinder 243 is fixedly connected to one side of the top end of the limiting plate 210. The top end of one of the connecting rods 241 is installed with the telescopic end of the second hydraulic cylinder 243. A groove 249 is provided at the bottom end of the abutment plate 242. A horizontal plate 244 is slidably connected to the opposite sides of the two abutment plates 242. Two pressure plates 245 are fixedly connected between the opposite sides of the two horizontal plates 244.

[0021] In this embodiment, the limiting plate 210 has an overall L-shaped shape. Sliding rods are slidably connected to the opposite sides of the two abutting plates 242. The end of the sliding rod away from the abutting plate 242 is fixedly connected to the side of the horizontal plate 244 away from the pressure plate 245. Sliding grooves matching the sliding rods are opened on the opposite sides of the two abutting plates 242. The sliding grooves limit the movement path of the sliding rods. There is a certain distance between the opposite sides of the horizontal plate 244 and the abutting plate 242. It should be noted that the reinforcement component 240 is used to reinforce track plates of the same specification, and the shape of the groove 249 can be opened according to the specific shape of the reinforcing rib on the track plate. When fixing the track plate, the track plate is placed inside the limiting plate 210, and one corner of the track plate abuts against the included angle of the limiting plate 210. At this time, the two abutting plates 242 are located above the reinforcing rib on the track plate, and the two pressure plates 245 are located on both sides of the top of the track plate.

[0022] like Figure 4 and Figure 5As shown, the reinforcement assembly 240 also includes two cylinders 246 that are respectively fixedly connected to the opposite sides of the two abutment plates 242. A round rod 247 is slidably connected to the inner wall of the cylinder 246. The bottom end of the round rod 247 is fixedly connected to the top end of the horizontal plate 244. A spring 248 is fixedly connected between the top end of the round rod 247 and the inner top wall of the cylinder 246.

[0023] In this embodiment, in the initial state, the spring 248 is in the released state, and at this time, the horizontal height of the bottom end of the horizontal plate 244 is lower than the horizontal height of the bottom end of the clamping plate 242.

[0024] like Figure 4 As shown, mounting blocks 250 are fixedly connected to opposite sides of the two abutment plates 242. A threaded rod 251 is threadedly connected to the inner wall of the mounting block 250. A fixing block 260 is fixedly connected to the top of the horizontal plate 244, and a threaded hole is formed at the top of the fixing block 260. The center of the threaded rod 251 and the center of the threaded hole in the fixing block 260 are on the same axis, and the diameter of the threaded hole matches the diameter of the threaded rod 251.

[0025] In this embodiment, in the initial state, the threaded rod 251 is not threadedly connected to the corresponding threaded hole, and there is a certain gap between the bottom end of the threaded rod 251 and the top end of the fixed block 260. Therefore, during the reinforcement operation of the reinforcing component 240, the fixed block 260 and the threaded rod 251 do not affect each other.

[0026] like Figure 4 As shown, a limiting rod 280 is fixedly connected to one side of the connecting rod 241, and the surface of the limiting rod 280 away from the connecting rod 241 is slidably connected to the inner wall of the limiting plate 210.

[0027] In this embodiment, two sliding grooves are provided on one side of the limiting plate 210, and the surfaces of the two limiting rods 280 away from the connecting rod 241 are slidably connected to the inner walls of the corresponding sliding grooves.

[0028] like Figure 5 As shown, the inner wall of the groove 249, the bottom end of the horizontal plate 244, and the bottom end of the pressure plate 245 are all fixedly connected with contact pads 270, which are rubber components.

[0029] In this embodiment, when the abutment plate 242, the cross plate 244 and the pressure plate 245 fix the track plate, the surface of the contact pad 270 contacts the surface of the track plate, and the contact pad 270 increases the friction force when fixing the track plate.

[0030] like Figure 2 and Figure 4 As shown, the bottom end of the horizontal plate 244 and the bottom end of the pressure plate 245 are located on the same horizontal plane.

[0031] In this embodiment, when the track plate is fixed, when the contact pad 270 at the bottom of the horizontal plate 244 contacts the top of the track plate, the contact surface at the bottom of the pressure plate 245 simultaneously contacts the top of the track plate.

[0032] like Figure 3 As shown, the top end of one of the connecting rods 241 is fixedly installed to the telescopic end of the second hydraulic cylinder 243 by bolts and nuts.

[0033] In this embodiment, the rectangular connecting block at the top of one of the connecting rods 241 matches the rectangular groove at the bottom of the telescopic end of the second hydraulic cylinder 243. When the connecting block is placed into the rectangular groove, the bolt is used to pass through the mounting hole of the connecting block and the mounting hole of the telescopic end of the second hydraulic cylinder 243 laterally, and the installation is completed by tightening the nut and the bolt. When it is necessary to disassemble one of the connecting rods 241 and the second hydraulic cylinder 243, the connection between the nut and the bolt is contacted, and the bolt is removed from the mounting hole, which is convenient for replacement when the clamping plate 242, the horizontal plate 244 and the pressure plate 245 are worn.

[0034] Working principle: When fixing the track plate, place the track plate inside the limiting plate 210, and make one corner of the track plate abut against the included angle of the limiting plate 210. At this time, two sides of the track plate are in contact with the surface of the limiting plate 210. Then, the controller starts the first hydraulic cylinder 220 to push the fixing plate 230 to move, so that the fixing plate 230 abuts and limits the track plate. After this operation is completed, drive the reinforcement component 240 to run, and the controller starts the second hydraulic cylinder 243 to run, pushing the connecting rod 241 to drive the pressing plate 242, the cross plate 244 and the pressure plate 245 to move downward. During the downward movement... During the process, the reinforcing ribs on the track plate will enter the groove 249, and the cross plate 244 and pressure plate 245 will contact the surface of the track plate and continue to move downward. Under the action of the track plate, the cross plate 244 and pressure plate 245 will press against the track plate and cannot move downward. At this time, the spring 248 will be compressed. When the pressing plate 242 presses against the reinforcing ribs on the track plate and cannot move downward, the second hydraulic cylinder 243 will be closed, and the two threaded rods 251 will be rotated respectively, so that the threaded rods 251 are threadedly connected to the threaded holes of the fixing block 260, thereby fixing the position of the cross plate 244. After this operation is completed, the track plate fixing operation is completed.

[0035] It should be noted that the first hydraulic cylinder 220 and the second hydraulic cylinder 243 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the first hydraulic cylinder 220 and the second hydraulic cylinder 243 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
