Description

Technical Field

[0001] This utility model relates to the field of metal product processing technology, and more specifically, to a positioning mechanism for metal product processing. Background Technology

[0002] In metal product processing, clamping and positioning are key to ensuring processing accuracy and efficiency. They can effectively fix the workpiece, prevent movement or vibration during processing, reduce errors, improve production efficiency, ensure the safety of operators, ensure the consistency and repeatability of processing, and thus improve the quality of the final product.

[0003] However, in the existing technology, when the positioning mechanism for metal product processing clamps and positions a cylindrical metal product, such as during turning, it is necessary to clamp and position the cylindrical metal product and make it rotate continuously. Each time a new cylindrical metal product is positioned, the positioning mechanism needs to be repeatedly adjusted to clamp and release the metal product. As the number of metal products processed increases, the processing efficiency of the metal products will be affected, and the repeated adjustment of the clamping mechanism also increases the labor intensity of the workers. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art, adapt to the needs of reality, and provide a positioning mechanism for metal product processing. This solves the technical problem that repeated adjustment of the positioning mechanism to clamp and release metal products in the prior art not only affects the processing efficiency of metal products, but also increases the labor intensity of workers.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a positioning mechanism for metal product processing, including a base, a motor fixedly connected to the outer wall of the base, a main shaft rotatably connected to the inner surface of the base, a receiving groove at the other end of the main shaft, a linkage block rotatably connected to the inner wall of the receiving groove via a torsion spring, a plurality of push grooves penetrating the outer wall of the linkage block, the inner wall of the push groove having an arc-shaped structure, a plurality of positioning plates disposed in the receiving groove, one end of the positioning plate extending into the push groove, and a push rod rotatably connected to the end of the positioning plate extending into the push groove, the outer wall of the push rod abutting against the arc-shaped inner wall of the push groove, the other end of the positioning plate penetrating through the inner wall of the receiving groove to the outside of the main shaft and slidably connected thereto, the motor... The rotating shaft passes through the base and the main shaft sequentially into the storage slot and is fixedly connected to the linkage block. A support ring is fixedly connected to the outer wall of the main shaft. By inserting the cylindrical metal product that needs to be positioned into the support ring, the positioning plate is positioned and fixed from the inner wall of the cylindrical metal product by the rotation of the motor. After the positioning plate has positioned the cylindrical metal product, it drives the cylindrical metal product to rotate continuously. After the cylindrical metal product is processed, the motor stops running and no longer drives the cylindrical metal product to rotate through the positioning plate. The positioning plate automatically stops positioning and fixing the cylindrical metal product, thereby realizing the rapid positioning, fixing and release of the cylindrical metal product, thereby increasing the efficiency of processing cylindrical metal products and reducing the labor intensity of workers when processing cylindrical metal products.

[0006] Preferably, the positioning plate extends in an arc shape through the storage groove to one end outside the main shaft, in the opposite direction of the rotation of the main shaft. After the positioning plate extends in an arc shape, the contact area between the positioning plate and the inner wall of the cylindrical metal product can be increased, thereby increasing the stability of the positioning plate when positioning and fixing the cylindrical metal product.

[0007] Preferably, a support rod is fixedly connected to the inner surface of the base. The support rod is a telescopic structure, and an arc-shaped support plate is fixedly connected to the other end of the support rod. The support rod supports the support plate, so that when the operator inserts the tubular metal product into the support ring, the other end of the tubular metal product is placed on the support plate. The support plate and the support ring cooperate to support the tubular metal product, thereby increasing the stability of the tubular metal product when rotating.

[0008] Preferably, the outer wall of the arc-shaped extension of the positioning plate is fixedly connected with a rubber anti-slip plate; the anti-slip plate allows the positioning plate to abut against the inner wall of the cylindrical metal product, increasing the stability of the cylindrical metal product when positioning and fixing it.

[0009] Preferably, the other side of the anti-slip plate has a comb-like structure. When the comb teeth of the anti-slip plate contact the inner wall of the cylindrical metal product, the anti-slip plate rotates along with the positioning plate. After the anti-slip plate rotates, the ends of its comb teeth contact the inner wall of the cylindrical metal product, and the anti-slip plate is still rotating. Therefore, the comb teeth of the anti-slip plate will begin to bend as the anti-slip plate rotates, thereby making the anti-slip plate fit against the inner wall of the cylindrical metal product. This increases the stability of the anti-slip plate when it contacts the cylindrical metal product, and prevents the anti-slip plate from directly contacting the inner wall of the cylindrical metal product. The friction between the two causes the cylindrical metal product to rotate first, thus preventing the anti-slip plate from failing to fit against the inner wall of the cylindrical metal product, which would affect the positioning and fixing effect of the cylindrical metal product.

[0010] Preferably, the inner arc-shaped surface of the pallet is rotatably connected with multiple rotating rods; the rotating rods prevent wear between the tubular metal product and the pallet when the tubular metal product rotates on the pallet.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, by setting up a base, motor, main shaft, storage groove, linkage block, push groove, positioning plate, push rod, and support ring, allows the cylindrical metal product to be positioned to be inserted into the support ring. Then, the motor rotates, causing the positioning plate to position and fix the cylindrical metal product from the inner wall. After the positioning plate has positioned the cylindrical metal product, it drives the cylindrical metal product to rotate continuously. After the cylindrical metal product is processed, the motor stops running and no longer drives the cylindrical metal product to rotate through the positioning plate. The positioning plate automatically stops positioning and fixing the cylindrical metal product, thereby achieving rapid positioning, fixing, and release of the cylindrical metal product, thus increasing the efficiency of processing cylindrical metal products and reducing the labor intensity of workers when processing cylindrical metal products.

[0013] 2. In this utility model, after the positioning plate extends through the storage groove to one end of the main shaft in an arc shape in the opposite direction of the rotation of the main shaft, the contact area between the positioning plate and the inner wall of the cylindrical metal product can be increased, thereby increasing the stability of the positioning plate when positioning and fixing the cylindrical metal product.

[0014] 3. In this utility model, when the comb teeth of the anti-slip plate contact the inner wall of the cylindrical metal product, the anti-slip plate rotates along with the positioning plate. After the anti-slip plate rotates, because the ends of its comb teeth contact the inner wall of the cylindrical metal product, and the anti-slip plate is still rotating, the comb teeth of the anti-slip plate will begin to bend along with the rotation of the anti-slip plate, thereby making the anti-slip plate fit against the inner wall of the cylindrical metal product. This increases the stability of the anti-slip plate when it contacts the cylindrical metal product, and prevents the anti-slip plate from directly contacting the inner wall of the cylindrical metal product. The friction generated between the two causes the cylindrical metal product to rotate first, thus preventing the anti-slip plate from failing to fit against the inner wall of the cylindrical metal product, which would affect the positioning and fixing effect of the cylindrical metal product.

[0021] like Figures 1 to 4As shown, this utility model relates to a positioning mechanism for metal product processing, comprising a base 1, a motor 2 fixedly connected to the outer wall of the base 1, a main shaft 3 rotatably connected to the inner surface of the base 1, a receiving groove 4 at the other end of the main shaft 3, a linkage block 5 rotatably connected to the inner wall of the receiving groove 4 via a torsion spring, a plurality of push grooves 6 penetrating the outer wall of the linkage block 5, the inner wall of the push groove 6 having an arc-shaped structure, a plurality of positioning plates 7 disposed in the receiving groove 4, one end of the positioning plate 7 extending into the push groove 6, and a push rod 8 rotatably connected to the end of the positioning plate 7 extending into the push groove 6, the outer wall of the push rod 8 abutting against the arc-shaped inner wall of the push groove 6, the other end of the positioning plate 7 penetrating through the inner wall of the receiving groove 4 to the outside of the main shaft 3 and slidably connected to it at the penetrating point, and the rotating shaft of the motor 2 sequentially penetrating the base 1 and the main shaft. The main shaft 3 is fixedly connected to the storage slot 4 and the linkage block 5. The outer wall of the main shaft 3 is fixedly connected to the support ring 9. The cylindrical metal product that needs to be positioned is inserted into the support ring 9. Then, the motor 2 rotates to make the positioning plate 7 position and fix it from the inner wall of the cylindrical metal product. After the positioning plate 7 has finished positioning it, it drives the cylindrical metal product to rotate continuously. After the cylindrical metal product is processed, the motor 2 stops running and no longer drives the cylindrical metal product to rotate through the positioning plate 7. The positioning plate 7 automatically stops positioning and fixing the cylindrical metal product, thereby realizing the rapid positioning, fixing and releasing of the cylindrical metal product, thereby increasing the efficiency of processing cylindrical metal products and reducing the labor intensity of workers when processing cylindrical metal products.

[0022] Furthermore, the positioning plate 7 extends in an arc shape through the storage groove 4 to one end of the main shaft 3 in the opposite direction of the rotation of the main shaft 3. After the positioning plate 7 extends in an arc shape, the contact area between the positioning plate 7 and the inner wall of the cylindrical metal product can be increased, thereby increasing the stability of the positioning plate 7 when positioning and fixing the cylindrical metal product.

[0023] Furthermore, a support rod 10 is fixedly connected to the inner surface of the base 1. The support rod 10 is a telescopic structure, and an arc-shaped support plate 11 is fixedly connected to the other end of the support rod 10. The support rod 10 supports the support plate 11, so that when the operator inserts the tubular metal product into the support ring 9, the other end of the tubular metal product is placed on the support plate 11. The support plate 11 and the support ring 9 cooperate to support the tubular metal product, thereby increasing the stability of the tubular metal product when rotating.

[0024] Furthermore, rubber anti-slip plates 12 are fixedly connected to the outer wall of the arc-shaped extension of the positioning plate 7; the anti-slip plates 12 allow the positioning plate 7 to abut against the inner wall of the cylindrical metal product, increasing the stability of the cylindrical metal product when positioning and fixing it.

[0025] Furthermore, the other side of the anti-slip plate 12 has a comb-like structure. When the comb teeth of the anti-slip plate 12 contact the inner wall of the cylindrical metal product, the anti-slip plate 12 rotates along with the positioning plate 7. After the anti-slip plate 12 rotates, the ends of its comb teeth contact the inner wall of the cylindrical metal product, and the anti-slip plate 12 is still rotating. Therefore, the comb teeth of the anti-slip plate 12 will begin to bend as the anti-slip plate 12 rotates, thereby making the anti-slip plate 12 fit against the inner wall of the cylindrical metal product. This increases the stability of the anti-slip plate 12 when it contacts the cylindrical metal product, and prevents the anti-slip plate 12 from directly contacting the inner wall of the cylindrical metal product. The friction generated between the two causes the cylindrical metal product to rotate first, thus preventing the anti-slip plate 12 from failing to fit against the inner wall of the cylindrical metal product, which would affect the positioning and fixing effect of the cylindrical metal product.

[0026] Furthermore, multiple rotating rods 13 are rotatably connected to the arc-shaped inner surface of the pallet 11; the rotating rods 13 prevent wear between the tubular metal product and the pallet 11 when the tubular metal product rotates on the pallet 11.

[0027] Working principle: This embodiment provides a positioning mechanism for metal product processing. In use, one end of the cylindrical metal product to be positioned is inserted into the support ring 9. Then, the motor 2 is started to rotate. The rotation of the motor 2 drives the linkage block 5 to rotate. When the linkage block 5 rotates, the arc-shaped inner wall of the push groove 6 opened on the outer wall of the linkage block 5 will push the push rod 8, thereby causing the push rod 8 to rotate and push the positioning plate 7 to move. After the positioning plate 7 moves, its arc-shaped extension end will abut against the inner wall of the cylindrical metal product, thereby completing the positioning and fixing of the cylindrical metal product. Since the positioning plate 7 abuts against the cylindrical metal product, and the inner wall of the push groove 6 can no longer push the positioning plate 7 to move, the positioning plate 7 will rotate together with the rotation of the linkage block 5, driving the cylindrical metal product, the main shaft 3 and the support ring 9 to rotate together.

[0028] After the cylindrical metal product is processed, the motor 2 stops running. The linkage block 5 is hinged to the inner wall of the receiving groove 4 by a torsion spring. Therefore, when the motor 2 stops running, the linkage block 5 will start to reset and twist under the torque of its own torsion spring. Similarly, during the reset and twisting process, the linkage block 5 gradually stops pushing the push rod 8, so that the positioning plate 7 loses the pushing force of the push rod 8, making it impossible for the positioning plate 7 to position and fix the cylindrical metal product. At this time, the processed cylindrical metal product can be pulled out.

[0029] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
