[0002] Automotive parts are the various units that make up the entire automotive parts processing system and the products that serve this process. By establishing R&D centers, parts manufacturers can achieve several advantages: speed – quickly meeting urgent market demands and rapidly developing products; accuracy – staying close to the market and achieving localization; and innovation – applying more new technologies to production, ensuring quality while reducing costs. In fact, some parts manufacturers are leading the way in developing new technologies for vehicle manufacturers. To reduce costs and capture market share, many multinational automotive parts companies are expanding internationally.

[0003] Automotive parts are typically subjected to hardness testing during the production process. However, existing hardness testing devices generally only use simple positioning mechanisms to fix the parts in place. This can lead to parts shifting during testing, or even parts breaking off and flying off, causing injury, thus reducing the stability and safety of the device. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies. By moving a movable plate to pull multiple through rods, the multiple through rods, along with the fixed block and two positioning frames, are raised and lowered, thereby allowing the top of the two positioning frames to contact the upper end of the component, thus restricting the position of the upper and lower ends of the component. This invention provides a precise positioning mechanism for automotive component hardness testing fixtures.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A precision positioning mechanism for a hardness testing fixture for automotive parts includes a base. Symmetrically arranged support rods are located on the upper end of the base. A top plate is located on the upper end of multiple support rods. A testing device is installed through the top plate. A testing head is located at the lower end of the testing device. Two symmetrically arranged through slots are formed on the base. Through tubes are slidably connected through each of the two through slots. Through rods are slidably connected through each of the multiple through tubes. A limiting mechanism is provided between two through rods on the same side. A lifting mechanism for raising and lowering the multiple through rods is located at the lower end of the base.

[0006] Preferably, the limiting mechanism includes a fixing block disposed on the upper end of a plurality of through rods, and a positioning frame is provided between two fixing blocks on the same side, and both positioning frames are L-shaped.

[0007] Preferably, the lifting mechanism includes two symmetrically arranged support plates disposed at the lower end of the base, a movable plate slidably connected between the two support plates, two symmetrically arranged movable slots opened on the movable plate, two symmetrically arranged movable blocks slidably connected in each of the two movable slots, and the ends of the plurality of through rods being connected to the plurality of movable blocks.

[0008] Preferably, a positioning plate is provided between the two support plates, and a power motor is provided at the upper end of the positioning plate. A threaded rod is rotatably connected between the output shaft of the power motor and the lower end of the base. The threaded rod passes through the movable plate and is threadedly connected to it.

[0009] Preferably, a transmission rod is rotatably connected between the two movable slots and the movable plate, a support plate is provided at the front end of the movable plate, a drive motor is provided at the upper end of the support plate, and the end of the transmission rod is connected to the end of the output shaft of the drive motor.

[0010] Preferably, both of the moving slots are provided with double-ended screws, the threads at both ends of the double-ended screws are turned in opposite directions, the outer walls of both double-ended screws are provided with worm gears, and the outer walls at both ends of the transmission rod are provided with worms that cooperate with the worm gears.

[0011] The beneficial effects of this utility model are: 1. By moving the movable plate, multiple through rods are moved, causing the multiple through rods to lift and lower the fixed block and two positioning frames, so that the top of the two positioning frames contacts the upper end of the component, thereby restricting the position of the upper and lower ends of the component.

[0012] 2. By moving multiple through rods, two positioning frames move relative to each other, causing the inner walls of the two positioning frames to contact the two sides of the component. This restricts the two ends of the component, ensuring its stability and safety during the testing process and providing convenience for users. Attached Figure Description

[0017] Reference Figure 1-3 A precision positioning mechanism for a hardness testing fixture for automotive parts includes a base 1. Symmetrically arranged support rods 3 are located on the upper end of the base 1. A top plate 4 is located on the upper end of multiple support rods 3. A testing device 5 is threaded through the top plate 4. A testing head is located at the lower end of the testing device 5. Two symmetrically arranged through slots 6 are opened on the base 1. Through tubes 7 are slidably connected through each of the two through slots 6. Through rods 8 are slidably connected through each of the multiple through tubes 7. A limiting mechanism is provided between the two through rods 8 on the same side. The limiting mechanism includes a fixing block 9 located on the upper end of the multiple through rods 8. A positioning frame 10 is provided between the two fixing blocks 9 on the same side. Both positioning frames 10 are L-shaped.

[0018] The lower end of the base 1 is provided with a lifting mechanism for raising and lowering multiple through rods 8. The lifting mechanism includes two symmetrically arranged support plates 2 arranged at the lower end of the base 1. A movable plate 11 is slidably connected between the two support plates 2. Two symmetrically arranged movable slots are opened on the movable plate 11. Two symmetrically arranged movable blocks 12 are slidably connected in each of the two movable slots. The ends of the multiple through rods 8 are connected to the multiple movable blocks 12.

[0019] A positioning plate 13 is provided between the two support plates 2. A power motor 14 is provided at the upper end of the positioning plate 13. A threaded rod 15 is rotatably connected between the output shaft of the power motor 14 and the lower end of the base 1. The threaded rod 15 passes through the moving plate 11 and is threadedly connected to it. By moving the moving plate 11, multiple through rods 8 are moved, causing the multiple through rods 8 to lift and lower along with the fixing block 9 and the two positioning frames 10, so that the top of the two positioning frames 10 contacts the upper end of the component, thereby limiting the position of the upper and lower ends of the component.

[0020] A transmission rod 20 is rotatably connected between the two movable slots and the movable plate 11. The front end of the movable plate 11 is provided with a support plate, and the upper end of the support plate is provided with a drive motor 16. The end of the transmission rod 20 is connected to the end of the output shaft of the drive motor 16.

[0021] Both movable slots are equipped with double-ended screws 18, with opposite thread directions at both ends of the double-ended screws 18. The outer walls of both double-ended screws 18 are equipped with worm gears 19, and the outer walls of both ends of the transmission rod 20 are equipped with worm gears 17 that cooperate with the worm gears 19. By moving multiple through rods 8, the two positioning frames 10 are driven to move relative to each other, so that the inner walls of the two positioning frames 10 come into contact with the two sides of the parts, thereby restricting the two ends of the parts and ensuring the stability and safety of the parts during the testing process, bringing convenience to people.

[0022] In use, when performing hardness testing on automotive parts, the parts are placed on the upper part of the base 1. The power motor 14 is started, causing the power motor 14 to drive the threaded rod 15 to rotate. Utilizing the threaded connection between the threaded rod 15 and the moving plate 11, and the sliding connection between the moving plate 11 and the two support plates 2, the moving plate 11 moves, pulling multiple through rods 8 to move. The multiple through rods 8, along with the fixing block 9 and the two positioning frames 10, rise and fall, thereby bringing the top of the two positioning frames 10 into contact with the upper end of the parts, thus restricting the upper and lower positions of the parts. Then, by starting the drive motor 16, the drive motor 16 drives the transmission rod 20 to rotate, causing the two ends of the transmission rod 20 to... The worm 17 on the outer wall rotates, and the worm wheel 19 rotates in conjunction with the worm 17, causing the worm wheel 19 to rotate and drive the double-ended screw 18 to rotate. The opposite threads at both ends of the double-ended screw 18 and the threaded connection between the moving block 12 and the double-ended screw 18 cause the moving block 12 to move, which in turn causes the through rod 8 to move. The movement of multiple through rods 8 causes the two positioning frames 10 to move relative to each other, so that the inner walls of the two positioning frames 10 come into contact with the two sides of the component, thereby restricting the two ends of the component and ensuring the stability and safety of the component during the testing process, bringing convenience to people (since the testing device 5 is existing technology, its related structure is not described in detail in this figure).
