Description

Technical Field

[0001] The utility model relates to the field of jigs, in particular to a grinding jig for an automobile bracket. Background Technique

[0002] An automobile bracket is a device used to support and maintain automobile components, ensuring the safety and stability of the vehicle; when the automobile bracket is produced, the bracket needs to be ground, and when grinding, the bracket needs to be fixed. Due to the weight and shape constraints of the bracket, generally a jig is used to fix it. For example, the patent network discloses a jig for grinding an automobile bracket (publication announcement number: CN221390519U). When this device is used, the adjusting bolt is toggled, and the clamping plate is pushed to move by the adjusting bolt. Further, the automobile bracket is clamped between the clamping plate and the bearing plate to realize the fixation of the automobile bracket. The reduction motor is started, and the second bevel gear rotates through the reduction motor. The rotation of the rotating shaft is caused by the meshing between the second bevel gear and the first bevel gear, so that the fixing frame rotates, and further the angle adjustment during the grinding of the automobile bracket can be realized;

[0003] However, for the grinding jigs for automobile brackets adopted in the above-mentioned disclosed patents and the existing market, there are still some deficiencies: the prior art uses a reduction motor to rotate the fixing frame to adjust the angle of the automobile bracket. However, the automobile bracket is fixed between the clamping plate and the bearing plate, and both are installed on the rotating shaft. Therefore, the force to prevent the automobile bracket from deflecting needs to act on the self-locking drive shaft of the reduction motor for a long time, which is very easy to cause damage to the reduction motor. Therefore, those skilled in the art have proposed a grinding jig for an automobile bracket. Summary of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4, the present utility model provides a technical solution for an automotive bracket grinding fixture: including a bracket mechanism 1, a fixing mechanism 2 and a deflection mechanism 4. The bracket mechanism 1 includes a bottom plate 101, and two side plates 102 are correspondingly installed on the upper surface of the bottom plate 101. The fixing mechanism 2 includes a strip-shaped plate 201 installed on the side surface of one of the side plates 102. Two round rods 202 are arranged directly below the strip-shaped plate 201. An arc-shaped rack 203 is jointly installed at the lower ends of the two round rods 202. A spring 204 is sleeved on each round rod 202 between the strip-shaped plate 201 and the arc-shaped rack 203. The upper ends of the two round rods 202 penetrate through the strip-shaped plate 201 and are installed with pull rings 205. The deflection mechanism 4 includes a second motor 401 installed on the inner side surface of the side plate 102 where the fixing mechanism 2 is installed. The driving end of the second motor 401 penetrates through the side plate 102 and is installed with a first gear 402. A second gear 403 that meshes with both the first gear 402 and the arc-shaped rack 203 is arranged on one side of the side plate 102. When it is necessary to deflect the clamped automotive bracket, pull up the pull ring 205 to drive the arc-shaped rack 203 to rise through the two round rods 202. The rising arc-shaped rack 203 releases the engagement with the second gear 403 and compresses the two springs 204 at the same time. Then, the second motor 401 operates to drive the first gear 402 to rotate. The rotating first gear 402 drives the moving seat 303 to rotate through the second gear 403. The rotating moving seat 303 can deflect the automotive bracket through the clamping mechanism 5 to perform angle adjustment.

[0023] Please refer to Figures 1-4 , further including an adjustment mechanism 3. The adjustment mechanism 3 includes two rotation slots 301 opened on the side surfaces of the two side plates 102. A rotating column 302 is rotatably installed in each rotation slot 301. The second gear 403 is fixedly connected to the nearest rotating column 302 and is at the same center of the circle. A moving seat 303 is jointly installed between the two rotating columns 302. A moving slot 304 is opened on the upper surface of the moving seat 303. The center of the side surface of the other rotating column 302 is installed with a first motor 306. The driving end of the first motor 306 extends into the moving slot 304 and is installed with a bidirectional screw 305 whose end is rotatably connected to the inner wall thereof. A threaded seat 307 adapted to the moving slot 304 is arranged on each thread of the bidirectional screw 305. The two threads on the bidirectional screw 305 have opposite directions. Internal threads are opened on the two threaded seats 307. The two internal threads are adapted to the two threads on the bidirectional screw 305. The two threaded seats 307 are slidably connected to the inner wall of the moving slot 304. When in use, the first motor 306 operates to drive the bidirectional screw 305 to rotate. The rotating bidirectional screw 305 can drive the two threaded seats 307 to approach each other, and thus can drive the L-shaped plates 501 to approach each other. On the contrary, when the first motor 306 drives the bidirectional screw 305 to reverse, the two L-shaped plates 501 can be made to move away from each other, and the distance between the two L-shaped plates 501 can be adjusted.

[0024] Please refer toFigures 1-3 It further includes a clamping mechanism 5. The clamping mechanism 5 includes two L-shaped plates 501 mounted on the upper surfaces of two threaded seats 307. A bearing plate 502 is mounted on the side surface of each L-shaped plate 501, and a hydraulic rod 503 is mounted on the upper surface of each L-shaped plate 501. The telescopic arm of each hydraulic rod 503 penetrates through the horizontal plate of the L-shaped plate 501 and is equipped with a clamping plate 504. When in use, place the vehicle bracket between the two bearing plates 502 and the clamping plates 504. The two hydraulic rods 503 extend to drive the two clamping plates 504 to approach the bearing plates 502 until the vehicle bracket is clamped.

[0025] Please refer to Figures 1-4 It further includes a dust-proof mechanism 6. The dust-proof mechanism 6 includes two mounting rods 601 mounted inside the moving groove 304 above the bidirectional screw 305, passing through the two threaded seats 307 and slidably connected to them. A first pleated curtain 602 sliding on the two mounting rods 601 is mounted between the two threaded seats 307. A second pleated curtain 603 sliding on the two mounting rods 601 is mounted between the side surface of each threaded seat 307 and the inner wall of the moving groove 304. When in use, when the two threaded seats 307 approach each other, the second pleated curtain 603 between them will be compressed, and the second pleated curtain 603 on one side of each threaded seat 307 will be stretched. When the two threaded seats 307 move away from each other, the first pleated curtain 602 between them will be stretched, and the first pleated curtain 602 on one side of each threaded seat 307 will be compressed. The first pleated curtain 602 and the second pleated curtain 603 can be used to close the upper port of the moving groove 304, avoiding grinding waste chips falling on the bidirectional screw 305 during the grinding of the vehicle bracket and affecting the movement of the threaded seat 307 on the bidirectional screw 305.

[0026] The working principle of the present utility model is as follows: When the first motor 306 operates to drive the bidirectional screw 305 to rotate, the rotating bidirectional screw 305 can drive the two threaded seats 307 to approach each other, and then drive the L-shaped plates 501 to approach each other. Conversely, when the first motor 306 drives the bidirectional screw 305 to reverse, the two L-shaped plates 501 can be made to move away from each other, and the distance between the two L-shaped plates 501 can be adjusted to adapt to vehicle brackets of various sizes;

[0027] Place the vehicle bracket between the two bearing plates 502 and the clamping plates 504. The two hydraulic rods 503 extend to drive the two clamping plates 504 to approach the bearing plates 502 until the vehicle bracket is clamped;

[0028] When it is necessary to deflect the clamped vehicle bracket, the upper pull ring 205 drives the arc-shaped rack 203 to rise through two round rods 202. The rising arc-shaped rack 203 disengages from the second gear 403 and compresses two springs 204 at the same time. Then, the second motor 401 operates to drive the first gear 402 to rotate. The rotating first gear 402 drives the moving seat 303 to rotate through the second gear 403. The rotating moving seat 303 can deflect the vehicle bracket through the clamping mechanism 5 to adjust the angle. After completion, the pull ring 205 is released to allow the two springs 204 to rebound and drive the arc-shaped rack 203 to descend and re-engage with the second gear 403, thereby fixing the second gear 403. It is not necessary to apply all the fixing force on the vehicle bracket to the drive shaft of the second motor 401, which prolongs the service life of the second motor 401;

[0029] When the two threaded seats 307 approach each other, the second hundred-fold curtain 603 between them will be compressed, and the second hundred-fold curtain 603 on one side of each threaded seat 307 will be stretched. When the two threaded seats 307 move away from each other, the first hundred-fold curtain 602 between them will be stretched, and the first hundred-fold curtain 602 on one side of each threaded seat 307 will be compressed. The first hundred-fold curtain 602 and the second hundred-fold curtain 603 can be used to close the upper port of the moving groove 304, preventing the grinding waste chips from falling on the bidirectional screw 305 during the grinding of the vehicle bracket and affecting the movement of the threaded seat 307 on the bidirectional screw 305.

[0030] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in the technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
