Description

Technical Field

[0001] This utility model belongs to the field of hardness testing technology, and more specifically, it relates to an auxiliary device for hardness testing. Background Technology

[0002] In numerous industrial production fields and materials research and development processes, accurate testing of material hardness is a crucial step. The hardness of a material is directly related to many key characteristics in practical use, such as wear resistance, deformation resistance, and overall performance. From metal processing and manufacturing to the production of polymer materials like plastics and rubber, and even the quality control of building materials, hardness testing is an indispensable core step.

[0003] A Rockwell hardness testing auxiliary device for metallic materials, authorized in China with publication number CN215727447U, includes a support body and a clamping screw. The support body is a cuboid with a central circular through hole, and its upper surface is configured with a V-shaped groove. A vertical cavity is provided on one side of the upper surface, and a pressing rod is provided in the vertical cavity. A pressing head is provided at the upper end of the pressing rod, and a supporting spring is sleeved on the lower half of the pressing rod. A limiting plate is provided at the bottom. The clamping screw extends laterally through the left and right side walls of the support body and into the circular through hole. One end of the clamping screw located in the circular through hole has an arc-shaped end, and the other end has a connecting bolt. A fixing strip is provided on each of the front and rear sides of the support body. A vertically penetrating clamping stud is provided on the fixing strip. The clamping stud is fixed by a locking nut at the top. A clamping spring is sleeved on the lower half of the clamping stud, and a clamping plate is provided at the bottom. This invention provides a fixed setting for the metal material being tested in both horizontal and vertical directions, making it simple to operate and easy to adjust. However, the device still has some shortcomings in use. For example, in actual operation, adjusting the clamping screw, pressing rod, and clamping stud still requires a certain amount of time and skill. When frequently changing different metal materials for testing, the operation process may be cumbersome, reducing testing efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a hardness testing auxiliary device in order to achieve a more practical purpose. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example:

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] This utility model provides a hardness testing auxiliary device, including a base 1, a testing head 6, and a controller 5. A processing table 2 is installed on the upper surface of the base 1. A placement groove 4 for placing workpieces is provided on the upper surface of the processing table 2. A protective cover 3 is provided on the outer side of the processing table 2. Connecting blocks 7 are installed on both sides of the inner wall of the protective cover 3. A snap-fit ​​block 8 is installed on the same side of the two connecting blocks 7. Clamping plates 13 for clamping workpieces are correspondingly provided on both sides of the upper surface of the placement groove 4. Wedge-shaped clamping plates 14 are installed on the opposite side of the two clamping plates 13. A sliding component for movement is provided at the bottom of the two clamping plates 13. The outer protective cover 3 protects the working environment of the test to prevent the workpiece from cracking or flying fragments. The two clamping plates 13 clamp and position the workpiece to prevent the workpiece from shifting during hardness testing. This setting automates the clamping and positioning work, eliminating the need for manual adjustment by the operator, saving time and effort, and facilitating subsequent testing work.

[0027] The sliding assembly includes a connecting rod 12, which is installed at the bottom of the clamping plate 13. A slider 11 is installed at the bottom of the connecting rod 12, and a corresponding groove 10 is provided on the upper surface of the placement groove 4. The slider 11 is slidably connected to the inner wall of the groove 10. The sliding assembly drives the clamping plates 13 on both sides to move. The characteristics of the groove 10 and the slider 11 are set to make the clamping plate 13 maintain relative stability.

[0028] The protective cover 3 has a connector 18 installed on one side, and a slot 25 is opened on one side of the base 1. A motor 21 is installed on the lower part of the inner wall of the slot 25. The motor 21 is electrically connected to the controller 5 through a wire. A screw 22 is installed at the output end of the motor 21. The top of the screw 22 is rotatably connected to the inner top of the slot 25. A connecting plate 20 is threadedly connected to the outer wall of the screw 22. By connecting the motor 21 to the controller 5 through a wire, the operator can operate the controller 5 to drive the motor 21, so that it drives the screw 22 to rotate, thereby driving the connecting plate 20 to rotate synchronously.

[0029] The groove 25 has vertical sliding grooves 24 on both sides of its inner wall. Sliding rods 23 are slidably connected to the inner walls of the two vertical sliding grooves 24. One side of each sliding rod 23 is fixed to the connecting plate 20. The vertical sliding grooves 24 and the sliding rods 23 cooperate to restrict the connecting plate 20, so that it can rise with the rotation of the screw 22, and finally drive the protective cover 3 to rise, thereby shielding and protecting the testing environment inside the placement groove 4, preventing accidents, workpiece breakage or other dangerous situations during hardness testing, and indicating the safety of the testing process.

[0030] A fixing rod 19 is installed on one side of the connecting plate 20. The top of the fixing rod 19 is fixed to the connector 18. This arrangement allows the connecting plate 20 to rise, which in turn causes the connector 18 to rise, thereby causing the protective cover 3 to rise.

[0031] Springs 15 are installed between the two connecting rods 12 and the inner wall of the placement groove 4. The springs 15 provide elasticity to the connecting rods 12 on both sides. When the workpiece is inspected and the protective cover 3 is lowered, the wedge-shaped plates 14 on both sides can be disengaged from the wedge-shaped grooves 16 more easily. Because of the springs 15, the springs 15 on both sides exert a pushing force on the connecting rod 12 on one side.

[0032] The processing table 2 has through slots 9 on both sides of its upper surface. The two through slots 9 are located directly above the corresponding snap-fit ​​block 8. The inner diameter of the two through slots 9 is larger than that of the snap-fit ​​block 8. The through slots 9 facilitate the protective cover 3 to drive the snap-fit ​​block 8 to rise, so that it passes through the through slots 9 and contacts the wedge-shaped snap-fit ​​plate 14.

[0033] The two snap-fit ​​blocks 8 have inclined surfaces 17 on their upper and lower surfaces, and wedge-shaped slots 16 on one side of each snap-fit ​​block 8. With the inclined surfaces 17, when the snap-fit ​​block 8 contacts the wedge-shaped plate 14, the wedge-shaped plate 14 is more easily squeezed and moved by the inclined surfaces 17. With the wedge-shaped slots 16, the wedge-shaped plate 14 is smoothly placed in the wedge-shaped slots 16.

[0034] The working principle of this embodiment is as follows: First, the operator places the workpiece to be tested for hardness into the placement slot 4 on the upper surface of the processing table 2. Then, the operator operates the controller 5, which drives the motor 21. The output end of the motor 21 is equipped with a screw 22. The motor 21 drives the screw 22 to rotate. Since the outer wall of the screw 22 is threadedly connected to the connecting plate 20, and both sides of the inner wall of the slot 25 are provided with vertical sliding grooves 24, the inner walls of the two vertical sliding grooves 24 are slidably connected with sliding rods 23. One side of the sliding rod 23 is fixed to the connecting plate 20. The rotation of the screw 22 causes the connecting plate 20 to rise under the cooperation and restriction of the vertical sliding grooves 24 and the sliding rods 23, thereby causing the connecting head 18 on one side of the protective cover 3 to rise, thus causing the protective cover 3 to rise and shield the testing environment inside the placement slot 4. When the protective cover 3 rises, the locking blocks 8 installed on the connecting blocks 7 on both sides of the inner wall of the protective cover 3, through the through groove 9 on the upper surface of the processing table 2, drive the locking blocks 8 to rise and clamp them on the placement slot 4. The wedge-shaped clamping plate 14 at the bottom of plate 13 contacts the clamping block 8. Since the upper and lower surfaces of the clamping block 8 are provided with inclined surfaces 17 and a wedge-shaped groove 16 is provided on one side, the wedge-shaped clamping plate 14 is squeezed by the inclined surfaces 17, causing the wedge-shaped clamping plate 14 to move the clamping plate 13. The sliding component at the bottom of the clamping plate 13 enables the clamping plate 13 to move stably, thereby clamping and positioning the workpiece in the placement groove 4 and preventing the workpiece from shifting during hardness testing. After the workpiece is tested, the protective cover 3 is lowered under the reverse drive of the motor 21. At this time, the springs 15 installed between the two connecting rods 12 and the inner wall of the placement groove 4 will generate elastic thrust on the connecting rods 12, making it easier for the wedge-shaped clamping plates 14 on both sides to disengage from the wedge-shaped groove 16, facilitating the clamping plate 13 to return to its original position, and making it easier to place and clamp the workpiece for the next test. This hardness testing auxiliary device realizes the clamping and positioning of the workpiece and the lifting and lowering operation of the protective cover 3 through automatic control, effectively improving the safety and efficiency of hardness testing.

Many modifications and variations will be apparent to those skilled in the art.
