A lifting plate is slidably connected to the top of the mounting frame, and a bracket is mounted on the top of the lifting plate. A bidirectional screw is rotatably connected inside the bracket, and a forward / reverse motor is mounted at one end of the bidirectional screw. A fixing mechanism is provided inside the bracket, and a lifting mechanism is provided inside the mounting frame. The fixing mechanism includes mounting plates symmetrically installed inside the bracket, with a clamping plate mounted on one side of the mounting plate. A pressing plate is symmetrically slidably connected inside the clamping plate, and a retraction rod is symmetrically installed between the pressing plate and the clamping plate. This allows for rapid adjustment and fixing according to the thickness of the metal product, satisfying the clamping effect for various specifications of metal products and effectively preventing the metal product from wobbling up and down during processing, thus greatly improving the positioning accuracy of the device. However, this patent still has the following problems.

[0004] While the aforementioned patent can quickly adjust and fix the metal product according to its thickness, thus satisfying the clamping effect of various specifications of metal products, the clamping plate only clamps from both sides. For metal products with irregular shapes or uneven surfaces, there may be problems with the clamping not being firm, which in turn affects the stability of the clamping. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the existing technology, the clamping plate only clamps through both sides, which may result in unstable clamping for metal products with irregular shapes or uneven surfaces, thus affecting the stability of clamping. Therefore, this invention proposes a metal product processing fixture with high positioning accuracy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a metal product processing fixture with high positioning accuracy, comprising a clamping structure, wherein the clamping structure includes a sliding plate, wherein a plurality of evenly distributed first springs are fixedly installed on the outer wall of the sliding plate, a mounting plate is fixedly installed on one end of each first spring, a rubber pad is provided on the outer wall of the mounting plate, a moving rod is fixedly installed on the outer wall of the mounting plate, one end of the moving rod passes through the sliding plate and is fixedly installed on a moving block, and a fixing structure is provided on the outer wall of the sliding plate; the fixing structure includes a fixing plate, the outer wall of the fixing plate is fixedly connected to the sliding plate, an electromagnet is fixedly installed on the top of the fixing plate, a second spring is fixedly installed on the top of the electromagnet, a top plate is fixedly installed on the top of the second spring, a plurality of evenly distributed pressure plates are fixedly installed on the bottom of the top plate, and an iron plate is fixedly installed on the bottom of the top plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when in use, the two sliding plates approach each other. When the rubber pads contact the outer wall of the workpiece, the first spring is compressed, and the moving rod drives the moving block to move. When the rubber pads on both sides are respectively attached to the two ends of the workpiece, the operator activates the electromagnet. The iron plate is attracted and descends.

In this way, workpieces of different shapes can be clamped, improving the range of applications.

[0015] 2. In this utility model, when the rubber pad is worn and needs to be replaced after long-term use, the operator rotates the handle, which drives the second threaded rod to rotate. The second threaded rod rises along the threaded hole, thereby driving the locking block to leave the slot. At this time, the operator can pull out the insert plate, thus replacing the rubber pad. Insert the new insert plate into the slot, rotate the handle in the opposite direction, the second threaded rod rotates, and the locking block enters the slot, thus completing the installation and improving the replacement efficiency.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as Figures 1-5 As shown, this utility model provides a metal product processing fixture with high positioning accuracy, including a clamping structure 2. The clamping structure 2 includes a sliding plate 201. Multiple evenly distributed first springs 202 are fixedly installed on the outer wall of the sliding plate 201. A mounting plate 203 is fixedly installed at one end of each first spring 202. A rubber pad 204 is provided on the outer wall of the mounting plate 203. A moving rod 205 is fixedly installed on the outer wall of the mounting plate 203. One end of the moving rod 205 passes through the sliding plate 201 and is fixedly installed with a moving block 206. A fixing structure 3 is provided on the outer wall of the sliding plate 201. The fixing structure 3 includes a fixing plate 301. The outer wall of the fixing plate 301 is fixedly connected to the sliding plate 201. An electromagnet 302 is fixedly installed on the top of the fixing plate 301. A second spring 303 is fixedly installed on the top of the electromagnet 302. A top plate 304 is fixedly installed on the top of the second spring 303. Multiple evenly distributed pressure plates 305 are fixedly installed on the bottom of the top plate 304. An iron plate 306 is fixedly installed on the bottom of the top plate 304.

[0025] The effect achieved by the entire embodiment 1 is as follows: during use, the two sliding plates 201 are brought close to each other. When the rubber pad 204 contacts the outer wall of the workpiece, the first spring 202 is compressed, and the moving rod 205 drives the moving block 206 to move. When the rubber pads 204 on both sides are in contact with the two ends of the workpiece, the operator activates the electromagnet 302. The iron plate 306 is attracted and descends. At this time, the iron plate 306 drives the top plate 304 and the pressure plate 305 to descend. The pressure plate 305 contacts the top of the moving block 206 and applies pressure to the moving block 206, so that the moving block 206 is fixed, which in turn causes the rubber pad 204 to be fixed. In this way, workpieces of different shapes can be clamped, thus improving the range of applications.

[0026] Example 2, as Figures 1-5As shown, further, the outer wall of the mounting plate 203 has a slot 207, the inner side wall of the slot 207 has a limiting groove 208, the inner wall of the limiting groove 208 has a threaded hole 209, the threaded hole 209 is threadedly connected to a second threaded rod 210, the top of the second threaded rod 210 is fixedly installed with a handle 211, and the bottom of the second threaded rod 210 is movably connected with a locking block 212.

[0027] Furthermore, an insert plate 213 is fixedly installed on the outer wall of the rubber pad 204, and a slot 214 is provided on the top of the insert plate 213.

[0028] Furthermore, the bottom of the slide 201 is provided with an adjustment structure 1, which includes an electric telescopic rod 101. A U-shaped seat 102 is fixedly installed at the telescopic end of the electric telescopic rod 101. An adjustment frame 103 is fixedly installed on the top of the U-shaped seat 102. A first threaded rod 104 is rotatably installed inside the adjustment frame 103. A motor 105 is fixedly installed on the outer wall of the adjustment frame 103. The output end of the motor 105 is fixedly connected to the first threaded rod 104. The outer wall of the first threaded rod 104 is threadedly connected to the two slides 201.

[0029] Furthermore, the outer wall of the locking block 212 is in contact with the inner wall of the limiting groove 208 to prevent the locking block 212 from rotating when the second threaded rod 210 rotates.

[0030] Furthermore, a limiting rod 307 is fixedly installed at the bottom of the top plate 304. The bottom of the limiting rod 307 is slidably inserted into the electromagnet 302 to prevent the top plate 304 from tilting.

[0031] Furthermore, the first threaded rod 104 is provided with two sections of threads with opposite textures. The first threaded rod 104 is connected to two slide plates 201 respectively through the two sections of threads with opposite textures. When the first threaded rod 104 rotates, the two slide plates 201 move closer to each other or further away from each other.

[0032] The effect achieved by the entire embodiment 2 is that when the rubber pad 204 wears out after long-term use and needs to be replaced, the operator rotates the handle 211, which drives the second threaded rod 210 to rotate. The second threaded rod 210 rises along the threaded hole 209, thereby driving the locking block 212 to leave the slot 214. At this time, the operator can pull out the insert plate 213, thus replacing the rubber pad 204. The new insert plate 213 is inserted into the slot 207, and the handle 211 is rotated in the opposite direction. The second threaded rod 210 rotates, and the locking block 212 enters the slot 214, thus completing the installation and improving the replacement efficiency.

[0033] Working principle: In use, the operator places the workpiece between the two sliding plates 201, and then starts the motor 105. The output end of the motor 105 drives the first threaded rod 104 to rotate, causing the two sliding plates 201 to move closer to each other. When the rubber pad 204 contacts the outer wall of the workpiece, the first spring 202 is compressed, and the moving rod 205 drives the moving block 206 to move. When the rubber pads 204 on both sides are in contact with the two ends of the workpiece, the operator starts the electromagnet 302. The iron plate 306 is attracted and descends. At this time, the iron plate 306 drives the top plate 304 and the pressure plate 305 to descend. The pressure plate 305 contacts the top of the moving block 206 and applies pressure to the moving block 206, so that the moving block 206 is fixed, which in turn causes the rubber pad 204 to be fixed. In this way, workpieces of different shapes can be clamped, thus improving the range of applications. When the rubber pad 204 wears out after prolonged use and needs to be replaced, the operator rotates the handle 211, which drives the second threaded rod 210 to rotate. The second threaded rod 210 rises along the threaded hole 209, thereby causing the locking block 212 to leave the slot 214. At this time, the operator can pull out the insert plate 213, thus replacing the rubber pad 204. The new insert plate 213 is inserted into the slot 207, and the handle 211 is rotated in the opposite direction. The second threaded rod 210 rotates, and the locking block 212 enters the slot 214, thus completing the installation and improving the replacement efficiency.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
