Description

Technical Field

[0001] The utility model relates to the technical field of sprocket shaft processing tools, and more specifically, to a tool for sprocket shaft processing. Background Technique

[0002] A tool for sprocket shaft processing, also known as a tooling fixture, is a device used in the mechanical manufacturing process to fix the sprocket shaft, make it occupy the correct position, and accept construction or detection. A tooling, that is, a process equipment. Ordinary tools for sprocket processing can only clamp sprocket shafts of one size specification. However, the sizes of sprocket shafts on the market are very different, which cannot meet the market demand. Moreover, after the ordinary sprocket shaft is fixed, the working range in the vertical direction cannot be adjusted.

[0003] In response to the above problems, as recorded in the application number 202322305789.9, the application name is a tool for sprocket shaft processing, which includes a box body. A plurality of guide rails are fixedly connected to the side wall of the box body. A clamping mechanism for clamping the sprocket shaft is arranged inside the box body. The clamping mechanism includes a fixing nut slidably connected to a plurality of guide rails. Sliding rings are arranged on the inner walls of the plurality of guide rails. A rotating rod is rotatably connected to the inner wall of the sliding ring. A gear is fixedly connected to the side wall of the rotating rod. A threaded sleeve is arranged on the side wall of the rotating rod. A fixing ring is rotatably connected to the side wall of the threaded sleeve. A clamping plate is fixedly connected to the inner wall of the spiral sleeve. The utility model is provided with a clamping mechanism, which can adjust a plurality of clamping plates to clamp sprocket shafts of different sizes, and expand the working range of the clamping mechanism through a plurality of guide rails, thereby improving the practicability of the device.

[0004] Although the device has many beneficial effects, there are still the following problems: Although the device can fix sprocket shafts of various sizes, there are some significant problems in the actual operation process. First, there are usually teeth on the circumferential outer wall of the sprocket shaft. When using simple clamping plates to fix it, the sprocket shaft is often damaged due to excessive clamping. And during processing, due to the small clamping area, the sprocket shaft is prone to slipping, which undoubtedly brings great trouble to the actual processing operation.

[0005] Second, when collecting the waste chips generated during processing, only the discharge pipe is used to collect and discharge the processed chips. However, in actual use, the chips often contain a certain amount of smaller chips. Relying solely on the discharge pipe for collection is not only a cumbersome process, but also the metal dust will be raised again. Moreover, the relatively loose waste chips are extremely troublesome during transportation and collection, and also occupy a large storage area, which undoubtedly causes great inconvenience to the actual use.

[0006] In view of this, we propose a tool for sprocket shaft processing. Content of the Utility Model

[0007] 1. Technical problem to be solved

[0008] The purpose of the present utility model is to provide a tooling for the processing of sprocket shafts, so as to solve the problems of poor clamping stability and inconvenient chip collection mentioned in the above background technology.

[0009] 2. Technical solution

[0010] A tooling for the processing of sprocket shafts includes a fixed plate. A fixed frame is arranged on the top of the fixed plate. A collection table is arranged on the top of the fixed plate. A connection box and a connection shell are arranged on the top of the collection table. An electric push rod II is arranged on the circumferential outer wall of the connection shell. The output ends of a plurality of the electric push rod IIs are connected with clamping blocks.

[0011] Preferably, a partition board is arranged on the inner wall of the fixed frame. Spring I is arranged on the outer walls on both sides of the partition board. The ends of a plurality of the spring Is are respectively connected with compaction plates.

[0012] Preferably, a sealing door is arranged on the front outer wall of the collection table. A through hole matching the fixed frame is opened at the bottom of the collection table. A collection port is arranged on the top of the collection table.

[0013] Preferably, a sliding plate is slidably connected to the bottom of the collection table. Sliders are arranged at the bottoms of a plurality of the sliding plates. A pulling block is arranged on the front outer wall of the slider.

[0014] Preferably, an electric push rod I is arranged on the top of the connection box. The output end of the electric push rod I is connected with a pressing block.

[0015] Preferably, the connection box and the collection table communicate with each other. The pressing block extends into the connection box.

[0016] Preferably, spring II is arranged on the inner walls of a plurality of the clamping blocks. The ends of a plurality of the spring IIs are respectively connected with pressing and positioning blocks.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the present utility model are as follows: When clamping and processing a sprocket shaft, first, the sprocket shaft can be placed inside two clamping blocks. Subsequently, with the driving action of a plurality of electric push rod IIs, the circumferential outer wall of the sprocket shaft is clamped. During the clamping process, a plurality of pressing and positioning blocks will perform corresponding telescopic changes according to the tooth condition on the outer wall of the sprocket shaft, so as to be able to fit more closely on the circumferential outer wall of the sprocket shaft, thereby increasing the contact area between the clamping block and the circumferential outer wall of the sprocket shaft, making the clamping more stable. Moreover, when a plurality of pressing and positioning blocks press between a plurality of teeth, it can also play a certain positioning role, effectively avoiding the problem of rotational slip of the sprocket shaft during the processing process, and better ensuring the stable progress of the processing;

[0019] Secondly, the waste chips generated during the processing will fall onto the slide plate inside the collection table through the collection port. After that, driven by the first electric push rod, the pressing block moves downward. During the downward movement of the pressing block, the compaction plate will be pressed toward both sides, thereby squeezing the metal chips to a certain extent, enabling the metal waste chips to be compacted into blocks, which is more convenient for subsequent unified processing and significantly reduces the storage space they occupy.

[0028] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0029] A tooling for the processing of a sprocket shaft includes a fixing plate 100. A fixing frame 110 is arranged on the top of the fixing plate x00. A collecting table 200 is arranged on the top of the fixing plate 100. A connection box 250 and a connection shell 300 are arranged on the top of the collecting table 200. An electric push rod two 310 is arranged on the circumferential outer wall of the connection shell 300. The output ends of a plurality of electric push rods two 310 are connected with clamping blocks 320, which is convenient for stably clamping the sprocket shaft by using the clamping blocks 320.

[0030] Specifically, a partition plate 120 is arranged on the inner wall of the fixing frame 110. Spring one 130 is arranged on the outer walls on both sides of the partition plate 120. The ends of a plurality of spring one 130 are respectively connected with a compaction plate 140, which is convenient for compacting metal scraps and facilitating the subsequent collection and treatment.

[0031] In some embodiments, the pressing position of the pressing block 270 is close to the area slightly behind the center of the plurality of compaction plates 140, so as to avoid the phenomenon that the plurality of compaction plates 140 are inclined when pressing one side.

[0032] Furthermore, a sealing door 210 is arranged on the front outer wall of the collecting table 200. A through hole 220 matching the fixing frame 110 is opened at the bottom of the collecting table 200. A collecting port 240 is arranged on the top of the collecting table 200, which is convenient for collecting the metal scraps generated during processing by using the collecting port.

[0033] Still further, a sliding plate 230 is slidably connected to the bottom of the collecting table 200. Sliders 231 are arranged at the bottoms of a plurality of sliding plates 230. A pulling block 232 is arranged on the front outer wall of the slider 231, which is convenient for taking out the slider 230.

[0034] Even further, an electric push rod one 260 is arranged on the top of the connection box 250. The output end of the electric push rod one 260 is connected with a pressing block 270, which is convenient for pressing the two compaction plates 140.

[0035] It is worth noting that the connection box 250 and the collecting table 200 are interconnected, and the pressing block 270 extends into the connection box 250.

[0036] It should be noted that springs two 330 are arranged on the inner walls of multiple clamping blocks 320, and the ends of the multiple springs two 330 are respectively connected with pressing and positioning blocks 340, which is convenient for better fitting and clamping the sprocket shaft.

[0037] In some embodiments: the device can be powered by an external conventional power supply and can be controlled by an external controller. The above all belong to the prior art.

[0038] In addition, the circuits, electronic components and modules involved in the present utility model are all prior art, which can be fully realized by those skilled in the art without further elaboration. The content protected by the present utility model does not involve the improvement of the internal structure and method.

[0039] Working principle: When clamping and processing the sprocket shaft, first place the sprocket shaft inside the two clamping blocks 320. Subsequently, with the driving action of multiple electric push rods two 260, clamp the circumferential outer wall of the sprocket shaft. During the clamping process, the multiple pressing and positioning blocks 340 will undergo corresponding telescopic changes according to the tooth conditions on the outer wall of the sprocket shaft, so as to be able to fit more closely on the circumferential outer wall of the sprocket shaft, thereby increasing the contact area between the clamping blocks 320 and the circumferential outer wall of the sprocket shaft, making the clamping more stable. Moreover, when the multiple pressing and positioning blocks 340 press between multiple teeth, they can also play a certain positioning role, effectively avoiding the problem of rotational slip of the sprocket shaft during the processing process, and better ensuring the stable progress of the processing. Secondly, the waste chips generated during the processing will fall onto the slide plate 230 inside the collection table 200 through the collection port 240. Then, driven by the electric push rod one 260, the pressing block 270 moves downward. During the downward movement of the pressing block 270, the compaction plate 140 will be pressed towards both sides, thereby squeezing the metal chips to a certain extent, so that the metal waste chips can be compacted into blocks, which is more convenient for later unified processing and significantly reduces the storage space they occupy.
