Description
Technical Field
[0001] This utility model relates to the field of diamond grinding wheel detection technology, and in particular to a diamond grinding wheel detection device. Background Technology
[0002] Diamond blanks require grinding with a grinding disc during processing to create multi-faceted surfaces. Since the grinding disc rotates at high speed during use, any vibration can affect grinding accuracy. Therefore, dynamic balancing is necessary. A dynamic balancing device is used to test the dynamic balance of rotating components, which are crucial parts of machinery. Due to uneven mass distribution and manufacturing and installation errors, the center of mass of rotating components often deviates from their axis of rotation. This generates centrifugal force during rotation, which not only increases the load on moving parts, accelerates wear, and reduces efficiency, but also causes vibration throughout the machine. This often results in reduced working accuracy, reliability, and stability. Therefore, dynamic balancing testing of rotating components is essential. This application proposes a diamond grinding disc testing device. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example
[0021] Please see Figures 1-5 This utility model provides a technical solution: a diamond grinding disc testing device, including a housing 1. A drive motor 3 is fixedly connected inside the housing 1. The output shaft of the drive motor 3 passes through the housing 1 and is fixedly connected to a drive shaft 4. A contact plate 5 is fixedly connected to the outside of the drive shaft 4. Multiple fixing posts are provided on the top of the contact plate 5. When installing the grinding disc, the fixing posts can be inserted into the mounting holes of the grinding disc to prevent it from rotating due to centrifugal force during testing. A locking sleeve 8 is detachably connected to the outside of the drive shaft 4 and above the contact plate 5. A locking component 9 is provided inside the locking sleeve 8. Two sliding grooves 11 are symmetrically opened inside the housing 1. Each slide groove 11 has a sliding rod 12 slidably connected inside, and a T-shaped rod 14 slidably connected inside the sliding rod 12. A ball bearing 15 is rolled inside the T-shaped rod 14. A linear displacement sensor 17 is fixedly connected to the outside of the sliding rod 12. Adjusting the position of the sliding rod 12 can change the position of the linear displacement sensor 17. The sliding rod inside the linear displacement sensor 17 is fixedly connected to one side of the T-shaped rod 14. The two sets of linear displacement sensors 17 can detect different positions of the grinding disc, thereby improving the comprehensiveness of the detection. A vibration sensor 10 is fixedly connected to the top of the housing 1. The vibration sensor 10 is in contact with the outer wall of the drive shaft 4.
[0022] Furthermore, the drive shaft 4 has a cavity 6 inside and an annular groove 7 inside, which communicates with the cavity 6. The locking assembly 9 includes a handle 91, which is fixed to the top of the locking sleeve 8. The locking sleeve 8 has an installation cavity 92 inside, and a lifting rod 93 is slidably connected inside the installation cavity 92. A sliding plate 94 is slidably connected inside the installation cavity 92. The lifting rod 93 is fixed to the top wall of the sliding plate 94. A spring 95 is sleeved on the outside of the lifting rod 93 between the top of the sliding plate 94 and the inner wall of the installation cavity 92. Multiple pull rods 96 are symmetrically rotatably connected to the bottom of the sliding plate 94. Multiple insert plates 97 are slidably connected inside the locking sleeve 8. One end of each insert plate 97 extends into the installation cavity 92 and is rotatably connected to the corresponding pull rod 96. The end of the insert plate 97 away from the pull rod 96 extends into the annular groove 7. This can replace the traditional fastening method to fix the grinding disc, which is convenient for locking and disassembling the grinding disc and can improve the efficiency of replacing the grinding disc during inspection.
[0023] Furthermore, the sliding rod 12 is provided with an internal chamber 13, and the bottom end of the T-shaped rod 14 extends into the internal chamber 13. A tension spring 16 is fixed between the base of the T-shaped rod 14 and the top of the inner wall of the internal chamber 13. The upward tension of the tension spring 16 can keep the ball 15 in contact with the bottom of the grinding disc, thereby detecting the vertical vibration of the grinding disc in real time.
[0024] Furthermore, two screws 18 are symmetrically rotatably connected inside the housing 1. The two screws 18 are respectively threadedly connected to the corresponding sliding rods 12. One end of the screw 18 passes through the housing 1 and is fixedly connected to a handwheel 19, which facilitates the adjustment of the position of the sliding rods 12 to achieve the detection effect of the two linear displacement sensors 17 at different positions of the grinding disc.
[0025] Furthermore, a protective cover 20 is fixedly connected to the top of the housing 1 and to the outside of the contact plate 5, which can protect the grinding disc and prevent the grinding disc from breaking and splintering out, causing injury to personnel.
[0026] Furthermore, an operation panel 2 is provided on the outside of the housing 1. The drive motor 3, vibration sensor 10 and linear displacement sensor 17 are all electrically connected to the operation panel 2, which facilitates centralized control of the equipment and data display, making it convenient for testers to use.
[0027] In summary: When using this equipment to inspect the grinding disc, first insert the grinding disc onto the drive shaft 4, and insert the mounting hole of the grinding disc into the fixed post at the top of the contact plate 5 to prevent it from rotating due to centrifugal force during inspection. Then, put the locking sleeve 8 on the top of the drive shaft 4, so that the insert plate 97 is inserted into the cavity 6. Under the pressure of the inner wall of the cavity 6, the insert plate 97 retracts into the mounting cavity 92, and drives the pull rod 96 to press against the slide plate 94 and the spring 95. When the locking sleeve 8 contacts the top wall of the grinding disc, the insert plate 97 moves down to the position of the annular groove 7. At this time, spring 95 pushes slide plate 94 downward to reset, thereby driving pull rod 96 to rotate and pressing insert plate 97 into annular groove 7, completing the fixation of locking sleeve 8. At this time, the grinding disc can fix the heat exchange locking sleeve 8 of contact plate 5 on drive shaft 4. During installation, the bottom of the grinding disc squeezes ball bearing 15 and drives ball bearing 15 to squeeze T-shaped rod 14, causing T-shaped rod 14 to slide downward to stretch tension spring 16. Under the action of tension spring 16, the ball bearing 15 can maintain contact with the bottom of the grinding disc. By rotating handwheel 19, screw 18 is driven to rotate. The position of the sliding rod 12 can be adjusted, thereby changing the contact position between the ball bearing 15 and the grinding disc. The drive motor 3 drives the drive shaft 4 to rotate, which in turn drives the grinding disc to rotate. When the grinding disc vibrates, the ball bearing 15 at its bottom transmits the vibration force to the T-shaped rod 14, causing the T-shaped rod 14 to bounce. Simultaneously, the T-shaped rod 14 drives the sliding rod of the linear displacement sensor 17 to slide, allowing the linear displacement sensor 17 to detect the vibration of the grinding disc. The vibration of the grinding disc is then transmitted to the vibration sensor via the drive shaft 4. Sensor 10 detects the axial vibration of the grinding disc. The detection data is displayed on the digital screen on the operation panel 2 for the tester to view. The protective cover 20 can protect the grinding disc from breaking and splintering, which could cause injury to personnel. After the test is completed, hold the handle 91 and pull the finger buckle on the lifting rod 93 to move the slide plate 94 upward. At this time, the slide plate 94 can drive the pull rod 96 to rotate and pull the insert plate 97 out of the annular groove 7. Then the locking sleeve 8 can be removed from the drive shaft 4 to facilitate the disassembly of the grinding disc.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
