[0002] Glass bead hardness testing is a testing process that determines the compressive strength, scratch resistance, or abrasion resistance of glass beads through specific methods. It is often used for quality control or material evaluation.

[0003] For example, CN221445701U discloses a glass hardness testing device, which includes a base, a platform, a testing box, a stylus, an elastic element, a pressure frame, and a winch. The platform is connected to the left side of the base, the testing box is connected to the upper left side of the base, the stylus is slidably connected to the lower part of the testing box, the elastic element is connected between the stylus and the testing box, the pressure frame is slidably connected inside the testing box, and the winch is connected to the upper side of the testing box.

[0004] However, in the existing technology, the spherical shape of the glass ball makes it difficult to obtain stable support and accurate pressure points in hardness testing. During the test, the ball is prone to rolling due to uneven force, resulting in inaccurate test results. Furthermore, when the pressure is too high and the glass ball breaks, it can easily cause injury to the testing equipment and operators. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that the spherical shape of a glass ball makes it difficult to obtain stable support and accurate pressure points during hardness testing, and that the ball is prone to rolling due to uneven force during testing, resulting in inaccurate test results. Therefore, this invention proposes a glass ball hardness testing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a glass ball hardness testing device, including an operating table, a support plate fixedly installed on the top of the operating table, a first electric cylinder fixedly installed at the center of the support plate, and a bearing component fixedly installed on the surface of the operating table.

[0007] The supporting assembly includes a positioning plate, a receiving tube, and a second electric cylinder. The positioning plate is fixedly installed on the table surface of the operating platform, and the second electric cylinder is fixedly installed inside the receiving tube. The axis of the second electric cylinder coincides with that of the first electric cylinder. One end of the piston rod of the second electric cylinder is rotatably connected to a connecting block, and a support block is fixedly connected to the top of the connecting block. A spherical groove is opened inside the support block.

[0008] Preferably, a pressing block is fixedly connected to one end of the piston rod of the first electric cylinder, and a sleeve is fixedly installed on the outer wall of the pressing block.

[0009] Preferably, the shape of the sleeve is adapted to the shape of the receiving tube.

[0010] Preferably, a protrusion is fixedly installed on the inner wall of the receiving tube, and the protrusion is located diagonally below the support block.

[0011] Preferably, a receiving cylinder is slidably connected to one side of the inside of the receiving cylinder, and the receiving cylinder and the protrusion are located on both sides of the second electric cylinder.

[0013] Preferably, a receiving groove is provided on the inner side of the connecting block, and a positioning rod is fixedly installed at the center of the positioning block.

[0014] Preferably, the positioning rod is rotatably connected to the connecting block, and a torsion spring is fixedly connected between the positioning block and the connecting block.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, a receiving tube is set to hold the glass ball. A support block is set in the receiving tube. The spherical groove in the support block can hold the glass ball, thereby preventing the glass ball from rolling when it is under pressure, ensuring the accuracy of the test results. Even if the glass ball breaks due to pressure, the resulting fragments will be concentrated in the spherical groove and will not cause damage to the surrounding personnel.

[0017] 2. In this utility model, by setting a sleeve on the outer wall of the pressing block, the flying of debris is further prevented. At the same time, a receiving cylinder for receiving debris is set inside the receiving cylinder. When the second electric cylinder drives the support block to move downward, the protrusion will push the support block to rotate around the positioning rod as the center, and pour the debris in the spherical groove into the receiving cylinder to complete the automatic receiving.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a glass ball hardness testing device, including an operating table 1, a support plate 3 fixedly installed on the top of the operating table 1, a first electric cylinder 4 fixedly installed at the center of the support plate 3, and a bearing component 2 fixedly installed on the table surface of the operating table 1.

[0026] The bearing assembly 2 includes a positioning plate 21, a receiving tube 22, and a second electric cylinder 23. The second electric cylinder 23 is fixedly installed inside the receiving tube 22. The axis of the second electric cylinder 23 coincides with that of the first electric cylinder 4. One end of the piston rod of the second electric cylinder 23 is rotatably connected to a connecting block 24. The top of the connecting block 24 is fixedly connected to a support block 25. A spherical groove 26 is opened inside the support block 25.

[0027] One end of the piston rod of the first electric cylinder 4 is fixedly connected to a pressing block 5. A sleeve 6 is fixedly installed on the outer wall of the pressing block 5. The shape of the sleeve 6 is adapted to the shape of the receiving tube 22.

[0028] The specific settings and functions of this embodiment are described below. The bearing component 2 is used to determine the position of the glass ball. It is fixedly installed on the table surface of the operating table 1 by the positioning plate 21. When in use, the glass ball is placed in the spherical groove 26. Then, the first electric cylinder 4 on the support plate 3 is activated. The first electric cylinder 4 pushes the pressing block 5 to move downward until it fits against the glass ball in the receiving tube 22. At the same time, the pressure on the glass ball is continuously increased to complete the hardness test.

[0029] The presence of the spherical groove 26 can prevent the glass ball from shaking significantly, thereby ensuring the accuracy of the test results. Even if the glass ball breaks due to pressure, the resulting fragments will be concentrated in the spherical groove 26, preventing injury to surrounding personnel. Furthermore, the sleeve 6 set on the pressing block 5 can also be fitted over the outside of the receiving cylinder 22 to further prevent fragments from splashing. The support block 25 is supported by the second electric cylinder 23 to ensure its stability.

[0030] Example 2: Figure 3 and Figure 4 As shown, a protrusion 27 is fixedly installed on the inner wall of the receiving cylinder 22. The protrusion 27 is located diagonally below the support block 25. A receiving cylinder 28 is slidably connected to one side of the inside of the receiving cylinder 22. The receiving cylinder 28 and the protrusion 27 are located on both sides of the second electric cylinder 23. A positioning block 29 is fixedly installed at one end of the piston rod of the second electric cylinder 23. The positioning block 29 is located inside the connecting block 24. A receiving groove 210 is opened on the inner side of the connecting block 24. A positioning rod 211 is fixedly installed at the center of the positioning block 29. The positioning rod 211 is rotatably connected to the connecting block 24. A torsion spring 212 is fixedly connected between the positioning block 29 and the connecting block 24.

[0031] The overall effect of this embodiment is that after the glass ball breaks during the hardness test, the second electric cylinder 23 is activated to drive the support block 25 downward. During the downward movement of the support block 25, one of its corners will contact the protrusion 27. Under the obstruction of the protrusion 27, the connecting block 24 will rotate around the positioning rod 211 as the center, and pour the debris in the spherical groove 26 into the receiving cylinder 28. After the debris is poured out, the second electric cylinder 23 pushes the support block 25 upward. At this time, the rebound of the torsion spring 212 will bounce the support block 25 back to the horizontal state.

[0032] The usage and working principle of this device are as follows: When in use, place the glass ball in the spherical groove 26, and then start the first electric cylinder 4 on the support plate 3. The first electric cylinder 4 pushes the pressing block 5 downward until it fits against the glass ball in the receiving tube 22. At the same time, the pressure on the glass ball is continuously increased to complete the hardness test. The presence of the spherical groove 26 can prevent the glass ball from shaking significantly, and the sleeve 6 on the outer wall of the pressing block 5 will be fitted onto the outside of the receiving tube 22.

[0033] Even if the glass ball breaks due to pressure, the resulting fragments will concentrate in the spherical groove 26 and will not cause injury to people in the vicinity. The sleeve 6 can also further prevent fragments from flying. After the glass ball breaks during the hardness test, the second electric cylinder 23 is activated to drive the support block 25 downward. During the downward movement of the support block 25, one of its corners will contact the protrusion 27. Under the obstruction of the protrusion 27, the connecting block 24 will rotate around the positioning rod 211 as the center, and pour the fragments in the spherical groove 26 into the receiving cylinder 28. After the fragments are poured out, the second electric cylinder 23 pushes the support block 25 upward. At this time, the rebound of the torsion spring 212 will bounce the support block 25 back to the horizontal state.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
