Description

Technical Field

[0001] This utility model relates to the field of hardness testing technology, and more specifically, to a hardness testing device for supervision purposes with strong applicability. Background Technology

[0002] Hardness testing ensures product quality and safety. By accurately assessing the hardness and strength of materials, it can determine whether they meet product design requirements and safety standards. This is crucial for ensuring product durability, safety, and efficiency. Hardness testing also reveals the physical and chemical properties of materials, providing a basis for material selection. Furthermore, by monitoring changes in material hardness, heat treatment process parameters can be adjusted to achieve ideal material properties. Hardness testing has a wide range of applications, suitable for various materials and fields, such as metals, plastics, and ceramics, in industries such as automotive, aerospace, machinery manufacturing, and construction.

[0003] During the supervision and management of products, operators often use corresponding hardness testing devices to test the hardness of raw materials. However, while existing hardness testing devices have basic hardness testing functions, they typically use bolts and nuts to fix the raw materials. This not only requires operators to use specific tools for disassembly and assembly, but also results in low efficiency. Therefore, improvements are needed. Utility Model Content

[0020] 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.

[0021] like Figures 1 to 5As shown, this utility model provides a highly applicable hardness testing device for supervision, including a base plate 1. Fixing plates 2 are fixedly installed on both the front and rear sides of the bottom of the base plate 1. A first motor 3 is fixedly installed on the front of the fixing plate 2. A double-threaded rod 4 is fixedly sleeved at the other end of the output shaft of the first motor 3. The other end of the double-threaded rod 4 passes through the fixing plate 2 and extends into the interior of the fixing plate 2, and is threadedly sleeved with a moving block 5. A limiting rod 6 located directly below the double-threaded rod 4 is fixedly sleeved between the fixing plates 2. The outer surface of the limiting rod 6 is movably sleeved with the interior of the moving block 5. A diagonal rod 7 is hinged to the outer surface of the moving block 5. The other end of 7 is hinged to a connecting block 8. Rectangular grooves 9 are provided on the left and right sides of the top of the base plate 1. The interior of the rectangular groove 9 is movably connected to the outer surface of the connecting block 8. A fixing frame 10 is fixedly connected to the top of the connecting block 8. The bottom of the fixing frame 10 is movably connected to the top of the base plate 1. When the first motor 3 starts running, it will cause the double threaded rod 4 to rotate, and cause the two moving blocks 5 to move horizontally in opposite directions under the limiting action of the limiting rod 6, and cause the two inclined rods 7 to move. At this time, under the limiting action of the rectangular groove 9, the two connecting blocks 8 drive the two fixing frames 10 to move horizontally in opposite directions.

[0022] The base plate 1 has a connecting frame 11 fixedly installed on its top. A pneumatic cylinder 12 is fixedly connected to the top of the connecting frame 11. The bottom end of the pneumatic cylinder 12 passes through the connecting frame 11 and extends into the inner cavity of the connecting frame 11, and a hardness testing head 13 is fixedly connected thereto. When the pneumatic cylinder 12 starts to run, it will cause the hardness testing head 13 to move vertically downward. When the bottom of the hardness testing head 13 comes into contact with the raw material, the hardness testing operation will be performed.

[0023] The outer side of the fixed frame 10 is movably sleeved with a rotating rod 14. The other end of the rotating rod 14 passes through the fixed frame 10 and extends into the inner cavity of the fixed frame 10, and is fixedly sleeved with a rotating plate 15. The left and right sides of the rotating plate 15 are hinged with connecting rods 16, and the other end of the connecting rod 16 is hinged with a rectangular block 17. When the rotating rod 14 is rotated, the rotating rod 14 will drive the rotating plate 15 to rotate, and the two connecting rods 16 will drive the two rectangular blocks 17 to move in opposite directions.

[0024] The rectangular block 17 is fixedly connected to the left side of the movable block 18. The left side of the movable block 18 is movably connected to the left side of the inner cavity of the fixed frame 10. The top of the movable block 18 passes through the fixed frame 10 and extends to the outside of the fixed frame 10. When the two rectangular blocks 17 move in opposite directions, under the limiting action of the fixed frame 10, the two movable blocks 18 will move horizontally in opposite directions and eventually the two movable blocks 18 will completely enter the interior of the fixed frame 10.

[0025] Among them, the outer surface of the movable block 18 is movably connected to the clamping block 19, and the outer surface of the clamping block 19 is movably connected to the outer surface of the fixed frame 10 and the base plate 1. When the two movable blocks 18 are disengaged from the interior of the clamping block 19, the fixing effect on the clamping block 19 will be released, so as to facilitate the replacement of the clamping block 19 and improve the efficiency of the operator in disassembling and assembling the clamping block 19.

[0026] The mounting plate 20 is fixedly connected to the right side of the fixing frame 10. A pull rod 21 is movably sleeved inside the mounting plate 20. The other end of the pull rod 21 passes through the mounting plate 20 and extends to the outside of the mounting plate 20 and is fixedly connected to a locking block 22. A gear 23 is meshed with the outer surface of the locking block 22. The inside of the gear 23 is fixedly sleeved with the outer surface of the rotating rod 14. When the pull rod 21 is pulled, the pull rod 21 will cause the locking block 22 to move horizontally backward under the limiting action of the mounting plate 20, and the locking block 22 will disengage from the outer surface of the gear 23, thereby releasing the fixing effect on the gear 23.

[0027] Among them, a spring 24 is movably sleeved on the outer surface of the pull rod 21. The tail end of the spring 24 is fixedly connected to the front of the mounting plate 20, and the front end of the spring 24 is fixedly connected to the back of the locking block 22. This design enables the locking block 22 to have a good reset effect during subsequent movement, thereby ensuring that the locking block 22 is always engaged with the gear 23, thus achieving the fixing effect on the rotating rod 14.

[0028] Working principle and usage process of this utility model:

[0029] First, place the raw material to be tested on the top of the base plate 1 and start the first motor 3. This will cause the double threaded rod 4 to rotate, and the two moving blocks 5 will move horizontally in opposite directions under the limiting action of the limiting rod 6. This will also cause the two inclined rods 7 to move. At this time, under the limiting action of the rectangular groove 9, the two connecting blocks 8 will drive the two fixing frames 10 to move horizontally towards each other. Finally, the two clamping blocks 19 will move towards each other along the outer surface of the base plate 1, achieving a rapid fixing effect on the raw material and improving the efficiency of the operator in fixing the raw material.

[0030] Once the fixing is complete, the pneumatic cylinder 12 is activated, causing the hardness testing head 13 to move vertically downwards. When the bottom of the hardness testing head 13 contacts the raw material, the hardness test is performed. When the clamping block 19 needs to be replaced, the pull rod 21 is pulled, causing the locking block 22 to move backwards and disengage from the outer surface of the gear 23, thereby releasing the fixing effect on the gear 23 and the rotating rod 14. At this time, rotating the rotating rod 14 will cause the rotating plate 15 to rotate and the two connecting rods 16 to move. Under the limiting action of the fixing frame 10, the two rectangular blocks 17 will drive the two moving blocks 18 to move horizontally in opposite directions, causing the moving blocks 18 to disengage from the inside of the clamping block 19, thus releasing the fixing effect on the clamping block 19. This achieves the purpose of facilitating the disassembly and assembly of the clamping block 19, improving the efficiency of the operator in disassembling and assembling the clamping block 19, and reducing the labor intensity of the operator.
