Abstract
Description
Technical Field
[0001] This utility model relates to the field of tooth plate fixing fixture technology, specifically a tooth plate fixing fixture. Background Technology
[0002] A thread rolling stencil, also known as a thread rolling die, is a tool used to process the external threads of bolts. During processing, a grinding machine is used to remove surface burrs. This grinding process involves using a fixture to secure the stencil to the grinding machine. Since the grinding primarily targets the teeth of the stencil, and these teeth have a certain angle, the angle of the stencil needs to be adjusted while it is being fixed. Because different stencil models have different tooth angles, the placement angle of the stencil needs to be manually adjusted. Multiple metal shims are then inserted to clamp and secure the stencil, maintaining a certain angle after fixing. This type of fixture is relatively cumbersome to operate and results in low grinding efficiency. Utility Model Content

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0019] like Figure 1-7 As shown, a toothed plate fixing fixture includes: The placement section is used to place the tooth plate 1 and can control the placement height of the tooth plate 1; The clamping part and the placement part are provided on the clamping part. The placement part can move on the clamping part and can clamp and fix the toothed plate 1 placed on the placement part. A support portion and a clamping portion are provided on the support portion, and the support portion can be used to control the rotation of the clamping portion by a predetermined angle.
[0020] Furthermore, the placement part includes a bottom groove 2 and a top plate 3. The bottom groove 2 has two grooves 4 inside, and the lower surface of the top plate 3 has two inclined grooves 5. Each groove 4 has a top block 6 inside. The bottom groove 2 has a fixing rod 7 that is slidably connected to the top block 6. It also includes a screw 8 that is threadedly connected to both top blocks 6. One end of the screw 8 has a nut 9. When the screw 8 rotates, the two top blocks 6 move in opposite directions. The lower surface of the top plate 3 has a guide rod 10 that passes through the bottom groove 2 and is slidably connected to it. The lower end of the guide rod 10 has a fixing block 11. A spring 12 is sleeved on the guide rod 10 and is located between the bottom groove 2 and the fixing block 11. The lower surface of the bottom groove 2 has two support legs 13.
[0021] When grinding the toothed plate 1, it needs to be placed on the top plate 3 first. After the toothed plate 1 is placed on the top plate 3, the center position of the toothed plate 1 should be basically aligned with the center position of the top plate 3, and the edge of the top plate 3 should be basically parallel to the edge of the toothed plate 1. After the toothed plate 1 is placed, by rotating the screw cap 9, the screw cap 9 will drive the screw rod 8 to rotate. After the screw rod 8 rotates, it can be connected to the two top blocks 6 by threads, and through the sliding connection between the top blocks 6 and the fixing rod 7, it can drive the two top blocks 6 to move closer or further apart. When the two top blocks 6 approach each other, the top plate 3 can be pushed upward by the cooperation between the upper end of the top block 6 and the inclined groove 5, and the distance between the top block 6 and the bottom groove 2 increases, thereby raising the height of the toothed plate 1 placed on the top plate 3. When the two top blocks 6 move away from each other, the distance between the top plate 3 and the bottom groove 2 shortens, thereby lowering the height of the toothed plate 1 on the top plate 3. By adjusting the position of the top blocks 6, the placement height of the toothed plate 1 can be easily adjusted, so that toothed plates 1 of different thicknesses can be placed, so that the toothed plate 1 can be effectively ground after placement.
[0022] The top block 6, top plate 3 and bottom groove 2 are all made of metal. The upper end of the top block 6 can be set into an arc shape to reduce the friction between the top block 6 and the top plate 3. The lower surface of the top block 6 needs to contact the bottom surface of the groove 4 so that the top block 6 can be formed, avoiding the pressure above from being applied to the fixing rod 7 and preventing the fixing rod 7 from deforming.
[0023] When the top plate 3 contacts the bottom groove 2, the shortest distance between the top plate 3 and the bottom groove 2 can be recorded as 0. When the distance between the top plate 3 and the bottom groove 2 is at its farthest, the farthest distance between the top plate 3 and the bottom groove 2 is 20mm. For each rotation of the nut 9, the top plate 3 can rise or fall by 0.5mm within this range, and a mark can be made on the nut 9 to observe whether the nut 9 has rotated a full circle. By controlling the number of rotations of the nut 9, it is easy to control the placement height of the toothed plate 1. The number of rotations of the nut 9 does not have to be an integer and can be adjusted according to the thickness of the toothed plate 1. For example, it can be rotated 5 and 1 / 3 or 1 / 5 times.
[0024] Furthermore, a sinkhole is provided on the upper surface of the top plate 3, and a placement plate 14 is rotatably connected inside the sinkhole. The upper surface of the placement plate 14 is higher than the upper surface of the top plate 3.
[0025] The side of the placement plate 14 is 1mm away from the side of the sink, and the upper surface of the placement plate 14 is 0.5mm away from the upper surface of the top plate 3. When placing the toothed plate 1, it needs to be placed directly on the placement plate 14. Since the toothed plate 1 is placed manually, there is an error in the accuracy of the placement. When the toothed plate 1 is clamped and fixed by the clamping part, the pressure of the clamping part on the toothed plate 1 will cause the toothed plate 1 to rotate. The toothed plate 1 can drive the placement plate 14 to rotate at the same time, thereby avoiding more friction between the toothed plate 1 and the top plate 3. When clamping and fixing the toothed plate 1, it is convenient to adjust the position of the toothed plate 1.
[0026] Furthermore, the clamping part includes a guide rail 15, with guide grooves provided on both the inner and outer sides of the guide rail 15. The support leg 13 on the lower surface of the bottom groove 2 is slidably connected to the guide groove on the outer side of the guide rail 15. Limiting blocks 16 are provided at both ends of the guide rail 15, and screws 17 are provided on the two limiting blocks 16. Screws 17 are rotatably connected to the two limiting blocks 16. A handwheel 18 is provided at one end of the screws 17. A slider 19 is slidably connected in the guide groove on the inner side of the guide rail 15. The slider 19 is threadedly connected to the screws 17. Clamping blocks 20 are provided on the slider 19 and one of the limiting blocks 16. Toothed grooves 21 are provided on the opposite side of the two clamping blocks 20.
[0027] The placement part can move on the guide groove outside the guide rail 15 via the support leg 13. After the toothed plate 1 is placed, the handwheel 18 is turned, which drives the screw 17 to rotate. The screw 17 is then connected to the slider 19 by a thread, which moves the slider 19 and the clamping block 20 on the slider 19. When the clamping block 20 moves, it will first contact the toothed plate 1 on the placement part, and then push the toothed plate 1 and the placement part to move. When the distance between the two clamping blocks 20 gets closer and closer, both clamping blocks 20 can contact the toothed plate 1. As the distance between the two clamping blocks 20 further shortens, the toothed plate 1 can be completely clamped and fixed by the two clamping blocks 20. When the toothed plate 1 is clamped and fixed, the height of the teeth on the upper surface of the toothed plate 1 will be higher than the height of the upper surface of the clamping block 20, so that when the grinding machine grinds the teeth of the toothed plate 1, it can only contact the teeth of the toothed plate 1 and not contact the clamping block 20.
[0028] The toothed groove 21 on the side of the clamping block 20 can increase the friction between it and the side of the toothed plate 1, thereby improving the fixing ability and stability of the toothed plate 1.
[0029] The limiting block 16, slider 19, and clamping block 20 are all made of metal. The clamping block 20 is fixed to the limiting block 16 and slider 19 by bolts. The limiting block 16 is fixed to the guide rail 15 by bolts.
[0030] Furthermore, the support part includes a support plate 22, on which a mounting groove is provided. A rotating shaft 23 is provided on the lower surface of the guide rail 15. The rotating shaft 23 is located inside the mounting groove and is rotatably connected to the support plate 22. A worm gear 24 is installed on the rotating shaft 23. A worm 25 that cooperates with the worm gear 24 is provided inside the mounting groove. One end of the worm 25 extends to the outside of the support plate 22, and a hexagonal screw head 26 is provided at one end of the worm 25.
[0031] Because the teeth of the toothed plate 1 have a certain angle, in order to facilitate the precise grinding of the teeth of the toothed plate 1 by the grinding wheel in the grinding machine, it is necessary to adjust the angle of the toothed plate 1 so that the angle of the teeth of the toothed plate 1 is basically parallel to the side of the grinding wheel. When controlling the angle of the toothed plate 1, a socket wrench is required. Through the cooperation of the socket wrench and the hexagonal screw head 26, the worm gear 25 can be rotated. Then, through the cooperation of the worm gear 25 and the worm wheel 24, the rotating shaft 23 can be rotated. The rotating shaft 23 drives the guide rail 15 to rotate, which in turn drives the toothed plate 1 fixed above to rotate. When the hexagonal screw head 26 is rotated one revolution by the socket wrench, the rotation angle of the toothed plate 1 is 0.5°. The rotation angle of the toothed plate 1 can be adjusted by controlling the number of revolutions of the hexagonal screw head 26. The hexagonal screw head 26 does not necessarily have to rotate a full revolution. For example, when the toothed plate 1 needs to rotate another 0.2°, it is only necessary to control the hexagonal screw head 26 to rotate about 1 / 3 revolution. The rotation error is within the allowable range.
[0032] In this fixed fixture, if two interconnected parts are rotatably connected, then they are connected by bearings.
[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
