Description

Technical Field

[0001] This application relates to the technical field of metal processing, and in particular to a positioning fixture for metal part processing. Background Art

[0002] Metal is a broad classification of chemical elements. It is usually a good conductor, capable of both conducting electricity and heat. This is because there are freely moving electrons inside the metal, making it excellent in terms of electric current and heat conduction. This enables metals to be widely used in electronic devices, wires, radiators, etc. At the same time, metals have high plasticity and ductility, and can change their shapes through deformation processes such as extrusion and stretching without breaking. This makes metals an ideal material in manufacturing and processing.

[0003] After retrieval, the existing Chinese patent publication number is: CN215615474U, which discloses a positioning fixture for facilitating metal plate processing in the technical field of metal processing. It includes support legs, a workbench, a lifting device, a fixing device, and a pushing device. The workbench is arranged on the support legs, the lifting device is arranged inside the workbench, the fixing device and the pushing device are arranged side by side on the workbench, and the lifting device is arranged below the fixing device; the fixing device includes a pushing component, guide rails, sliders, a pressing plate, and edge plates. The pushing component is arranged on the workbench, the guide rails are arranged on both sides of the pushing component, two groups of guide rails are arranged in parallel, the sliders are arranged on the pushing component, the pressing plate is arranged on the sliders, the edge plates are arranged inside the two groups of guide rails, two groups of edge plates are provided and the extension lines of the two groups of edge plates intersect, and the two groups of edge plates are arranged opposite to the pressing plate. This utility model relates to the technical field of metal processing. This positioning fixture for facilitating metal plate processing achieves the purpose of effectively preventing the edge of the metal plate from warping and slipping out of the fixing device during the process of pushing and pressing by setting a stepped edge plate with a wider upper part and a narrower lower part. It also achieves the purpose of being able to push the metal plate out of the range of the stepped clamping structure of the edge plate with a wider upper part and a narrower lower part by setting a push plate, avoiding the metal plate being stuck by the edge plate and making it more convenient to lift the metal plate. By setting a lifting plate, it is more convenient to take out and replace the metal plate after processing when there are baffles around.

[0004] The specification of the above patent mentions that "by setting a stepped edge plate with a wider upper part and a narrower lower part, it can effectively prevent the edge of the metal plate from warping and slipping out of the fixing device". Although the above patent can fix the plate-shaped metal part and prevent it from slipping out of the fixing device, it cannot adapt to thinner metal parts during specific use. When clamping and processing such thinner metal parts, it may cause the middle of the metal part to bulge, which will lead to inaccurate sizing or hole position positioning of the metal part during processing.

[0005] In view of the related technologies described above, the inventor provides a positioning fixture for metal part processing. Summary of the Invention

[0015] By adopting the above technical solution, the bottom box provides a sliding space for the sliding column and at the same time limits its sliding range, so that it always performs a parallel sliding motion, and the top piece thereon will also be driven to move when it slides.

[0016] Optionally, the outer part of the sliding block is slidably connected to the inner wall of the sliding groove, and the top end of the bottom block is slidably connected to the bottom end of the top box.

[0017] By adopting the above technical solution, the sliding groove provides a sliding space for the sliding block and at the same time plays a role in limiting the position, ensuring that it performs a linear translation motion.

[0022] Optionally, the top end of the top block is in contact with the bottom end of the sliding column, and the bottom end of the limiting block is in contact with the top end of the top box.

[0023] By adopting the above technical solution, when the top block slides and translates, it will lift the sliding column, thereby lifting the top piece, achieving the purpose of lifting the metal parts thereon.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The following will Figure 1 - be Figure 3 further described in detail with reference to the attached

[0032] A positioning fixture for metal part processing, referring to Figures 1 - 3 , includes a top box 1. The top box 1 is the head of the entire fixture, responsible for fixing and positioning the metal parts. The first motor 2 is installed at the top end of the inner wall of the top box 1 to provide power. Driven by the first motor 2, two short rods 4 are rotatably connected to the outer sides of the bottom end. The short rods 4 connected to the outer sides of the bottom end of the turntable are rotatably connected to the bottom end of the slider 5. Here, when the short rod 4 rotates, it will drive the slider 5 to move. Connected by the short rod, the outer side is slidably connected to the inner wall of the chute 7, and the bottom end is fixedly connected to the bottom block 6. Here, when the slider 5 moves, it will drive the bottom block 6 below it to move together, so as to achieve the effect of spreading or stretching the metal parts to a certain extent, ensuring the accuracy of the size or hole position positioning of the metal parts during processing. And the chute 7 here is used to support the sliding of the slider 5, making it perform a parallel linear translation movement. The support column 8 is a support structure slidably connected to the four corners of the inner wall of the top box 1, and the top end is fixedly connected to the limit block 9. Here, the limit block 9 is used to limit the maximum sliding distance of the top box 1 on the support column 8. The two threaded columns 10 threadedly connected to the front end of the top box 1 are used for limiting when the top box 1 presses the metal parts to reach the ideal distance, so that the top box 1 and the support column 8 are both fixed in their corresponding positions.

[0033] Reference Figure 1 and Figure 3 The bottom box 11 serves as the base of the entire positioning jig, providing certain support for the entire jig. When the second motor 12 rotates, it drives the threaded rod 13 thereon to rotate together. The top block 14 threadedly connected to the threaded rod 13 will translate back and forth when the threaded rod 13 rotates. The function of the top disc 15 here is to limit the maximum translation distance of the top block 14 to ensure that it does not exceed the control range of the threaded rod 13. When the top block 14 moves, it will gradually come into contact with the sliding column 16, and then when it continues to move forward, it will lift the sliding column 16. The top piece 17 at the top of the sliding column 16 will also be lifted, and then the top piece 17 will lift the processed metal part thereon, facilitating the staff to recycle it. The box legs 18 fixed to the bottom end of the bottom box 11 support the entire jig structure and ensure its stability.

[0034] The implementation principle of the embodiment of this application is as follows: When in use, the staff can first place the metal part to be positioned and processed inside the bottom box 11, and then pull the top box 1. The top box 1 will move downward under the pull of manpower. Then, when the top box 1 moves downward as a whole, the slider 5 will first come into contact with the metal part. After the two are completely in close contact, the threaded column 10 can be screwed. The threaded column 10 will fix the support column 8 and the top box 1 in the same position. Then, start the first motor 2. The first motor 2 will start to rotate driven by electricity. The rotation of the first motor 2 will drive the turntable 3 to rotate. When the turntable 3 rotates, it will drive the two sliders 5 thereon to move in opposite left and right directions, and at the same time drive the bottom block 6 thereon to translate in the opposite direction. The function of the chute 7 here is to ensure that the sliders 5 and the bottom block 6 make complete translational movements without deviation in direction. At this time, the bottom block 6 will move on the surface of the metal part. Also, because the metal part and the bottom block 6 are already in a close contact state, moving the bottom block 6 at this time only spreads and stretches the metal part to a certain extent to ensure the accuracy of dimensions or hole positions during processing. After everything is ready, the processing of the metal part can begin. After the processing is completed, the staff can start the second motor 12. Then, the second motor 12 will drive the threaded rod 13 thereon to rotate together under the action of electricity. Because the threaded rod 13 and the top block 14 are threadedly connected, when the threaded rod 13 rotates, it will drive the top block 14 thereon to perform translational movement back and forth. The main function of the top disc 15 here is to limit the maximum movement range of the top block 14 to ensure that it always moves on the surface of the threaded rod 13 without detaching. The top block 14 moves forward driven by the threaded rod 13. Then, the top end of the ramp surface of the top block 14 will contact the bottom end of the ramp surface of the sliding column 16, and then squeeze the sliding column 16. Because the sliding column 16 is slidably connected to the inner wall of the bottom box 11, the top block 14 will lift the sliding column 16 along the inner wall of the bottom box 11 when moving forward. Then, when the sliding column 16 is lifted, it will drive the top piece 17 thereon to be lifted together, achieving the purpose of lifting the metal part to facilitate the staff to recycle it.
