Description

Technical Field

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

[0002] A power module is a power supply device that can be directly mounted on a printed circuit board. It is mainly used in switching equipment, access equipment, PTZ video power connection and other equipment. Before the power module is completed, workers usually need to cut a large power module into multiple smaller modules, clamp the modules, and then use a grinding device to grind the burrs on the edges of the modules.

[0003] Traditional power module positioning devices can generally only position the two ends of the power module, and cannot position the four ends. Therefore, when the grinding components are grinding the surface of the power module, the power module may move back and forth, which may affect the grinding effect on the surface of the power module. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a positioning device for power module processing. This solves the problem mentioned in the background art that traditional power module positioning devices can generally only position the two ends of the power module and cannot position the four ends. Therefore, when the grinding components are grinding the surface of the power module, the power module may move back and forth, which may affect the grinding effect on the surface of the power module.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for power module processing, comprising a base plate, characterized in that: four support legs are fixedly installed at the bottom of the base plate, the four support legs are arranged in a rectangular array at the bottom of the base plate, a sliding groove is opened on the base plate, the sliding groove extends through the base plate, a bidirectional threaded rod is rotatably installed in the sliding groove, a drive motor is fixedly installed at the outer end of the bidirectional threaded rod, two sliding blocks are arranged opposite each other in the sliding groove, both sliding blocks are slidably installed in the sliding groove, each of the two sliding blocks has a threaded hole, a bidirectional threaded rod is engaged in the threaded hole, and a first clamping plate is fixedly installed on the inner end surface of the sliding block.

[0006] By adopting the above technical solution, the drive motor opens the bidirectional threaded rod, which drives the sliding block to move within the slide groove, thereby clamping the two ends of the power module with the first clamping plate. Then, by rotating the knob, the adjusting rod is rotated. When the adjusting rod rotates, it causes the second clamping plate to move inward, thereby clamping the front and rear ends of the power module with the second clamping plate. Because the first and second clamping plates cooperate with each other, the four ends of the power module can be positioned well, thus preventing the power module from shaking during the surface polishing and affecting the polishing effect.

[0007] Preferably, the first clamping plate has an adjusting rod rotatably mounted at both its front and rear ends. A knob is fixedly mounted on the outer end surface of the adjusting rod, and a second clamping plate is rotatably mounted on the inner end surface of the adjusting rod. Two stabilizing rods are fixedly mounted on the second clamping plate, and both stabilizing rods penetrate into the first clamping plate.

[0008] Using the above technical solution, rotating the knob causes the adjusting rod to rotate. When the adjusting rod rotates, it causes the second clamping plate to move inward, thereby clamping the front and rear ends of the power module. Since there is a stabilizing rod installed on the second clamping plate, the second clamping plate can be kept stable when the adjusting rod moves it.

[0009] Preferably, a grinding component is provided on the upper surface of the base plate near the rear end, and two mesh screens are provided on the base plate, with the diameter of the holes in the mesh screens being 0.05mm.

[0010] Using the above technical solution, the grinding components set on the base plate can effectively grind the power module, and the sieve set on the base plate can ensure that the powder generated during grinding enters the collection hopper.

[0011] Preferably, a collection hopper is movably inserted into the bottom of the base plate, and a handle is fixedly installed on the outer end surface of the collection hopper.

[0012] Using the above technical solution, after the power module is polished, the staff can pull out the collection bucket through the handle to process the collected metal powder.

[0013] Preferably, a fixing plate is fixedly installed at the front end of the upper surface of the base plate, an electric telescopic rod is fixedly installed on the outer end surface of the fixing plate, the telescopic end of the electric telescopic rod extends through the fixing plate, and a push plate is fixedly installed on the telescopic end of the electric telescopic rod.

[0014] By adopting the above technical solution, the electric telescopic rod installed on the fixed plate is controlled to drive the push plate installed on the output end to move. Then, the bottom of the push plate and the surface of the base plate are in contact. Therefore, when the push plate moves, it can effectively push the powder generated on the base plate through the sieve into the collection hopper for collection.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The positioning device for processing the power module uses a drive motor to open a bidirectional threaded rod, which moves a sliding block within a groove. This causes the first clamping plate to clamp both ends of the power module. Then, rotating a knob causes an adjusting rod to rotate. When the adjusting rod rotates, it moves the second clamping plate inward, clamping both the front and rear ends of the power module. The cooperation between the first and second clamping plates effectively positions the four ends of the power module, preventing the power module from shaking during surface polishing and affecting the polishing effect.

[0016] 2. The positioning device for processing the power module controls the electric telescopic rod installed on the fixed plate, thereby moving the push plate installed on the output end. The bottom of the push plate is in contact with the surface of the base plate. Therefore, when the push plate moves, it can effectively push the powder generated on the base plate through the strainer into the collection hopper for collection, thus effectively cleaning the metal dust generated on the base plate. After the power module is polished, the operator can pull out the collection hopper by the handle to carry out the subsequent processing of the collected metal powder. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] Referring to Figures 1-4, a positioning device for power module processing is described. Four support legs 2 are fixedly installed on the bottom of a base plate 1, arranged in a rectangular array. A sliding groove 3 extends through the base plate 1. A bidirectional threaded rod 4 is rotatably mounted within the sliding groove 3, and a drive motor 5 is fixedly installed at the outer end of the bidirectional threaded rod 4. Two sliding blocks 6 are arranged opposite each other within the sliding groove 3, and both sliding blocks 6 are slidably mounted within the sliding groove 3. Both sliding blocks 6 have threaded holes 7, and bidirectional threaded rods 4 are engaged in the threaded holes 7. A first clamping plate 8 is fixedly installed on the inner end surface of the sliding block 6. Adjusting rods 9 are rotatably installed at both ends of the first clamping plate 8. A knob 10 is fixedly installed on the outer end surface of the adjusting rod 9. A second clamping plate 11 is rotatably installed on the inner end surface of the adjusting rod 9. Two stabilizing rods 12 are fixedly installed on the second clamping plate 11, and both stabilizing rods 12 penetrate into the first clamping plate 8.

[0021] Working principle: The four support legs 2 installed at the bottom of the base plate 1 provide good support for the base plate 1. When the power module needs to be polished, the operator first places the power module on the base plate 1, then turns on the drive motor 5, which drives the bidirectional threaded rod 4 installed on the output end to rotate. When the bidirectional threaded rod 4 rotates, it drives the sliding block 6 to move in the slide groove 3, thereby clamping the two ends of the power module with the first clamping plate 8 installed on the sliding block 6. After both ends of the power module are clamped, the operator rotates the knob 10 to further polish the module. The adjusting rod 9 is rotated, which causes the second clamping plate 11 to move inward, thereby clamping the front and rear ends of the power module. Since the second clamping plate 11 is equipped with a stabilizing rod 12, the adjusting rod 9 can keep the second clamping plate 11 stable when it moves. Therefore, the first clamping plate 8 and the second clamping plate 11 work together to position the four ends of the power module well, thus preventing the power module from shaking during the polishing process and affecting the polishing effect. Example

[0022] Referring to Figures 1-4, a positioning device for power module processing is described. A sliding groove 3 is formed on the base plate 1, extending through the base plate 1. A grinding assembly 13 is disposed on the upper surface of the base plate 1 near the rear end. Two mesh screens 14 are disposed on the base plate 1, with holes in each mesh screen 14 having a diameter of 0.05 mm. A collecting hopper 15 is movably inserted into the bottom of the base plate 1, and a handle 16 is fixedly installed on the outer end surface of the collecting hopper 15. A fixing plate 17 is fixedly installed at the front end of the upper surface of the base plate 1, and an electric telescopic rod 18 is fixedly installed on the outer end surface of the fixing plate 17. The telescopic end of the electric telescopic rod 18 extends through the fixing plate 17, and a push plate 19 is fixedly installed on the telescopic end of the electric telescopic rod 18.

[0023] Working principle: Because the base plate 1 has a groove 3 that extends through the base plate 1, some of the dust generated during the grinding of the power module will fall into the collection hopper 15 through the groove 3. After the grinding of the power module is completed, the operator removes the power module from the base plate 1 by canceling its positioning. Then, the operator controls the electric telescopic rod 18 installed on the fixing plate 17 to move the push plate 19 installed on the output end. The bottom of the push plate 19 is in contact with the surface of the base plate 1. Therefore, when the push plate 19 moves, it can effectively push the dust generated on the base plate 1 through the strainer 14 into the collection hopper 15 for collection. This effectively cleans the metal dust generated on the base plate 1. After the grinding of the power module is completed, the operator can pull out the collection hopper 15 through the handle 16 to process the collected metal dust.
