Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, specifically to a grinding device for gear processing. Background Technology

[0002] A gear grinding device is a mechanical device used to remove burrs and chamfers from the edges of gears. It mainly uses the rotation of a grinding wheel to grind the edges of the gears, thereby improving the meshing accuracy of the gears and reducing transmission noise.

[0003] For example, a gear grinding device disclosed in patent CN221494498U, although it places the gear to be processed on the upper surface of a support base plate, so that the gear to be processed fits into the upper outer wall of four arc-shaped mounting plates, and the four arc-shaped mounting plates fix the gear to be processed to the outer wall of four rubber pads through the action of threaded rods, and the support base plate moves upward through the action of hydraulic rods, thereby fixing the gear to be processed between the support base plate and the fixed circular plate; however, in actual use, when it is necessary to grind the edge of the shaft hole of the bevel gear and the outer edge of the upper and lower end faces, the four arc-shaped mounting plates move inward, making it difficult to fix the bevel gear in different placement states, thus affecting the grinding of the bevel gear, so it needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a gear grinding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A gear grinding device includes a clamp on a grinding machine. Multiple intersecting mounting slots are radially arranged on the upper side of the clamp. A fixing assembly for fixing a bevel gear is provided within each mounting slot. The fixing assembly includes mounting blocks disposed opposite each other within the mounting slots. Abutment plates are disposed opposite each other on the upper sides of the mounting blocks. A rotatable rotating plate is disposed between the opposing abutment plates. The multiple rotating plates abut against the outer wall of the bevel gear. A locking element is also provided on the abutment plates for locking the rotating plates. A driving assembly for moving the mounting blocks within the mounting slots is also provided within the mounting slots.

[0007] Furthermore, the abutment plate is provided with through holes; the locking element includes a first threaded rod provided on the rotating plate, with both ends of the first threaded rod extending out of the corresponding through holes, and a locking nut threadedly connected to the extended end of the first threaded rod, the locking nut pressing against the abutment plate to fix the rotating rod.

[0008] Furthermore, the drive assembly includes a second threaded rod rotatably disposed in a corresponding mounting slot, the thread of the second threaded rod passing through the corresponding mounting block, a first bevel gear being provided at one end of the second threaded rod, a rotating rod being vertically disposed in the mounting slot located at the center of the clamp, and a second bevel gear being provided at the upper end of the rotating rod that meshes with a plurality of first bevel gears.

[0009] Furthermore, a fixing plate is provided at the opening end where the mounting slots intersect, one end of the second threaded rod passes through the fixing plate, and the first bevel gear is fixedly installed at one end of the second threaded rod.

[0010] Furthermore, the clamp has a cavity, in which a servo motor is installed. The output end of the servo motor is connected to the lower end of the rotating rod via a coupling.

[0011] Furthermore, a lever is fixedly provided at the upper end of the rotating plate.

[0012] Furthermore, multiple heat dissipation holes are arranged on the outer wall of the cavity.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, by setting up a fixing component, when grinding the outer edge of the bevel gear, the rotating plate is first rotated and stored between the opposing abutment plates. Then, the mounting blocks are brought closer together so that the abutment plates move towards the center of the clamp. Next, the shaft hole on the bevel gear is fitted over the abutment plates that have moved closer together. The corresponding mounting blocks are then driven away from each other by the driving component, so that the abutment plates can be pressed against the inner wall of the shaft hole, thereby fixing the bevel gear so that the grinding component can grind the edges of the upper and lower end faces of the bevel gear.

[0015] In this invention, when grinding the edge of the shaft hole on the bevel gear, the corresponding mounting block and abutment plate are driven apart by the drive assembly. Then, the smaller end face of the bevel gear is placed upwards and positioned at the center of the clamp. At this time, the drive assembly drives the two mounting blocks in the corresponding mounting groove to move closer together, so that the abutment plate can abut against the edge of the outer wall of the bevel gear, thus initially fixing the bevel gear. Then, the rotating plate is flipped so that it rotates out between the two abutment plates, so that one end can abut against the corresponding tooth groove or the outer wall of the bevel gear. At this time, the rotating plate is locked by the locking member, thereby further limiting the bevel gear in this state, so that the fixing effect of the bevel gear is better.

[0016] In this invention, the driving component drives the corresponding mounting blocks and abutment plates to move away from each other. Then, the larger end face of the bevel gear is turned upward and positioned at the center of the clamp. At this time, the driving component drives the two mounting blocks in the corresponding mounting slot to move closer to each other, so that the abutment plate can abut against the edge of the outer wall of the bevel gear, thus initially fixing the bevel gear. Then, the rotating plate is flipped so that it rotates out between the two abutment plates and presses against the larger end face of the bevel gear. At this time, the rotating plate is locked by the locking component, thereby further limiting the bevel gear in this state and making the fixing effect of the bevel gear better.

[0030] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0031] The following is in conjunction with the appendix Figures 1-7 This embodiment will be described in further detail.

[0032] Combination Figures 1-7 As shown, a gear grinding device in this embodiment includes a clamping seat 101 on a grinding machine tool 100. The upper side of the clamping seat 101 is provided with a plurality of intersecting mounting grooves 200 along its radial direction. The mounting grooves 200 are provided with fixing components for fixing the bevel gear 102.

[0033] The fixing assembly includes a mounting block 300 disposed opposite to the mounting groove 200. The upper side of the mounting block 300 is provided with an abutment plate 301 opposite to the mounting block 300. A rotatable rotating plate 400 is provided between the opposing abutment plates 301. Multiple rotating plates 400 are used to abut against the outer wall of the bevel gear 102. The abutment plate 301 is also provided with a locking member for locking the rotating plate 400. The mounting groove 200 is also provided with a driving assembly for driving the mounting block 300 to move relative to each other within the mounting groove 200.

[0034] In actual use, the clamping seat 101 is rotatably mounted on the grinding machine tool 100. Specifically, the grinding machine tool 100 is also equipped with a grinding ridge assembly, which is a conventional structure. It mainly includes a U-shaped mounting bracket 103, a rotatable threaded shaft 104 on the mounting bracket 103, and a drive motor 106 on the side wall of the mounting bracket 103. The output end of the drive motor 106 is connected to the threaded shaft 104 to drive the threaded shaft 104 to rotate. The threaded shaft 104 is threaded with a movable plate 109, and the mounting bracket 103 is also equipped with a guide rod. A guide rod is slidably installed through the moving plate 109. An electric push rod 105 is installed on the moving plate 109. The output end of the electric push rod 105 is provided with a rotatable grinding blade 108 via a power motor 107. Thus, in actual use, the bevel gear 102 to be processed is fixed to the clamping seat 101 by a fixing assembly. Specifically, the grinding machine tool 100 is provided with a mounting cavity, and a stepper motor 110 is provided in the mounting cavity. The output end of the stepper motor 110 is connected to the bottom wall of the clamping seat 101, so that the stepper motor 110 can drive the clamping seat 101 to rotate.

[0035] When it is necessary to grind the edges of the upper and lower end faces of the bevel gear 102 and the edges of its shaft hole 800, the drive motor 106 drives the threaded shaft 104 to rotate, so that the moving plate 109 can drive the electric push rod 105 to move to the position above the edge of the bevel gear 102 to be ground. At this time, the electric push rod 105 drives the power motor 107 and the grinding blade 108 to move down as a whole until the grinding blade 108 contacts the edge to be ground. Then the power motor 107 drives the grinding blade 108 to rotate to grind the edge of the bevel gear 102. At the same time, the clamp 101 rotates to drive the bevel gear 102 to rotate, thereby realizing the grinding process of the bevel gear 102.

[0036] In practical use, such as Figure 5 As shown, the abutment plate 301 is fixedly installed on the upper side of the mounting block 300; through the setting of the drive component, the drive component can drive the corresponding two mounting blocks 300 to move closer or further away from each other in the corresponding mounting groove 200, thereby enabling the mounting blocks 300 to drive the corresponding abutment plates 301 to move closer or further away from each other, so that the abutment plates 301 press against the outer side of the bevel gear 102 or press against the inner wall of the shaft hole 800 of the bevel gear 102, thereby fixing the bevel gear 102 on the clamp 101;

[0037] In actual use, when it is necessary to grind the outer edge of the bevel gear 102, the rotating plate 400 is first rotated and stored between the opposing abutment plates 301. Then, the mounting blocks 300 are brought closer to each other so that the abutment plates 301 move toward the center of the clamp 101. Next, the shaft hole 800 on the bevel gear 102 is fitted over the abutment plates 301 and the corresponding mounting blocks 300 are driven away from each other by the drive assembly. This allows the abutment plates 301 to press against the inner wall of the shaft hole 800, thereby fixing the bevel gear 102 so that the grinding assembly can grind the edges of the upper and lower end faces of the bevel gear 102.

[0038] When it is necessary to grind the edge of the shaft hole 800 on the bevel gear 102, the corresponding mounting block 300 and the abutment plate 301 are driven to move away from each other by the drive assembly. Then, the smaller end face of the bevel gear 102 is placed upwards and positioned at the center of the clamp 101. At this time, the drive assembly drives the two mounting blocks 300 in the corresponding mounting groove 200 to move closer to each other, so that the abutment plate 301 can abut against the edge of the outer wall of the bevel gear 102, so that the bevel gear 102 is initially fixed. Then, the rotating plate 400 is flipped so that it rotates out between the two abutment plates 301, so that one end can abut against the corresponding tooth groove or the outer wall of the bevel gear 102. At this time, the rotating plate 400 is locked by the locking member, so that the bevel gear 102 in this state can be further limited, so that the bevel gear 102 is fixed better.

[0039] When the corresponding mounting block 300 and abutment plate 301 are driven away from each other by the drive assembly, the larger end face of the bevel gear 102 is then turned upwards and positioned at the center of the clamp 101. At this time, the drive assembly drives the two mounting blocks 300 in the corresponding mounting groove 200 to move closer to each other, so that the abutment plate 301 can abut against the edge of the outer wall of the bevel gear 102, thereby initially fixing the bevel gear 102. Then, the rotating plate 400 is flipped so that it rotates out between the two abutment plates 301 and abuts against the larger end face of the bevel gear 102. At this time, the rotating plate 400 is locked by the locking member, thereby further limiting the bevel gear 102 in this state, so that the bevel gear 102 is fixed better.

[0040] Specifically, the abutment plate 301 is provided with a through hole; the locking member includes a first threaded rod 500 provided on the rotating plate 400, with both ends of the first threaded rod 500 extending out of the corresponding through holes, and the extended ends of the first threaded rod 500 are threadedly connected to a locking nut 501, which presses against the abutment plate 301 to fix the rotating rod 404.

[0041] In this embodiment, the rotating plate 400 is rotatably mounted between the two abutment plates 301 by the through hole and the first threaded rod 500. In actual use, when the locking nut 501 is loosened, the rotating plate 400 can be flipped. When the rotating plate 400 rotates to a suitable angle, the locking nut 501 is tightened, so that the two locking nuts 501 can press against the corresponding side wall of the abutment plate 301, thereby fixing the rotating plate 400.

[0042] In order to facilitate the operator to drive the rotating plate 400 to flip, in this embodiment, a lever 401 is fixedly provided at the upper end of the rotating plate 400. The lever 401 facilitates the operator to drive the rotating plate 400 to flip.

[0043] Combination Figures 3-4 As shown, in this embodiment, the driving component includes a second threaded rod 201 rotatably disposed in the corresponding mounting groove 200. The thread of the second threaded rod 201 passes through the corresponding mounting block 300. One end of the second threaded rod 201 is provided with a first bevel gear 402. A rotatable rotating rod 404 is vertically disposed in the mounting groove 200 located at the center of the clamp 101. The upper end of the rotating rod 404 is provided with a second bevel gear 403 that meshes with a plurality of first bevel gears 402.

[0044] In actual use, the clamp 101 has a cavity 406, and a servo motor 405 is installed in the cavity 406. The output end of the servo motor 405 is connected to the lower end of the rotating rod 404 through a coupling. Since the width of the mounting block 300 is adapted to the width of the mounting groove 200, the mounting groove 200 can limit the mounting block 300, so that the servo motor 405 drives the rotating rod 404 to rotate in both directions. The rotation of the rotating rod 404 can drive the second bevel gear 403 to rotate, and then the second bevel gear 403 can drive multiple first bevel gears 402 to rotate, so that the first bevel gears 402 can drive the corresponding second threaded rod 201 to rotate, and the rotation of the second threaded rod 201 can drive the corresponding mounting block 300 to move.

[0045] In actual use, a fixing plate is provided at the opening end of the intersection of the mounting grooves 200. One end of the second threaded rod 201 extends through the fixing plate into the intersection. The first bevel gear 402 is fixedly installed at one end of the second threaded rod 201. Specifically, the two ends of the second threaded rod 201 are respectively installed on the corresponding side wall of the mounting groove 200 and the fixing plate through bearings, so that the second threaded rod 201 can be rotated and installed.

[0046] The lower end of the rotating rod 404 is rotatably mounted on the bottom wall of the mounting groove 200 via a bearing, so that the rotating rod 404 can be rotatably mounted, and the second bevel gear 403 is fixedly mounted on the upper end of the rotating rod 404.

[0047] Specifically, in order to install the servo motor 405, a detachable mounting cover is provided at the lower end of the clamp 101. The mounting cover covers the lower end of the clamp 101 to form a cavity. In order to power the servo motor 405, a battery for powering the servo motor 405 is provided in the cavity. In order to dissipate heat from the servo motor 405, multiple heat dissipation holes 111 communicating with the cavity 406 are provided on the outer wall of the mounting cover. Through the setting of the heat dissipation holes 111, the heat generated by the servo motor 405 during operation can be dissipated.

[0048] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
