[0002] In industrial production, grinding technology is a widely used processing method for processing various types of workpieces. During the grinding process, the quality and performance of the grinding wheel are crucial to the processing effect. However, due to various factors during manufacturing, installation and use, the grinding wheel may deflect or become unstable. Therefore, a deflection test fixture is needed to test the grinding wheel in order to improve the use effect of the grinding wheel.
[0003] In the prior art, the traditional runout test is usually measured by an operator using a manual instrument to determine the runout of the grinding wheel, resulting in low measurement accuracy. During use, the existing runout test fixture has a relatively fixed structure and the sizes of grinding wheels for different purposes are different. This results in the inability to fully match different grinding wheels when replacing them, thereby reducing the flexibility of the test fixture and affecting the test effect.
[0004] Therefore, a grinding wheel rapid deflection test fixture is needed to solve the problem that the existing deflection test fixture has low flexibility during use, resulting in poor use effect of the deflection test fixture. Utility Model Content

[0024] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Embodiment 1
[0026] See also Figure 1-Figure 8 The utility model provides a technical solution: a grinding wheel rapid deflection test fixture, comprising a test fixture body 1, a support plate 2 is installed on the top left side of the test fixture body 1, a grinding wheel body 15 is arranged on the right side of the support plate 2, a slide groove a5 is opened on the right side of the support plate 2, a moving block 6 is slidably connected to the inner wall of the slide groove a5, a clamping roller 10 is rotatably connected to the right side of the moving block 6, and rubber blocks 9 are installed on the front and rear sides of the moving block 6. Through the setting of the rubber blocks 9, the moving block 6 can move up and down more smoothly during adjustment to prevent deviation; the two rubber blocks 9 are slidably connected to the right side of the slide groove a5, and the clamping roller 10 is arranged on the top of the grinding wheel body 15.
[0027] First, install the grinding wheel body 15 on the right side of the support plate 2, and then drive the moving block 6 to move downward along the slide groove a5, and drive the clamping roller 10 to move downward, so as to clamp the grinding wheel body 15. At the same time, rubber blocks 9 are installed on the front and back sides of the moving block 6, so as to prevent the position of the clamping roller 10 from shifting after the grinding wheel body 15 is clamped, thereby preventing the test results from being affected, thereby facilitating the use of workers. After the adjustment is completed, the workers use the test fixture body 1 to perform a deflection test on the grinding wheel body 15.
[0028] Embodiment 2
[0029] On the basis of Example 1, in order to facilitate the adjustment of the clamping roller 10 to adapt to grinding wheel bodies 15 of different sizes, a knob 3 is provided on the top of the support plate 2, and a screw 4 is installed at the bottom end of the knob 3, and the screw 4 passes through the top of the support plate 2; the moving block 6 is threadedly connected to the outside of the screw 4, and the bottom end of the screw 4 is rotatably connected to the bottom of the support plate 2, so that the screw 4 is driven to rotate by turning the knob 3, and the clamping roller 10 is synchronously driven to be adjusted up and down.
[0030] After the grinding wheel body 15 is installed, the worker first turns the knob 3 to drive the screw 4 to rotate synchronously. Due to the threaded connection between the moving block 6 and the screw 4, the moving block 6 is driven to move downward, and at the same time, the clamping roller 10 is driven to apply a certain downward pressure to the grinding wheel body 15, thereby clamping the grinding wheel body 15 downward, so that the test fixture body 1 can be suitable for grinding wheel bodies 15 of different sizes, thereby improving the flexibility and effect of the use of the test fixture body 1.
[0031] Embodiment 3
[0032] On the basis of the second embodiment, in order to prevent the screw 4 from self-rotating, a mounting groove 8 is provided at the bottom of the support plate 2, a gear 7 is provided on the inner wall of the mounting groove 8, a block 13 is provided on the left side of the gear 7, and the block 13 passes through the left wall of the mounting groove 8.
[0033] During the rotation of the screw 4, the gear 7 will be driven to rotate on the inner wall of the mounting groove 8. At this time, since the clamping block 13 passes through the left wall of the mounting groove 8, it is clamped into the tooth groove of the gear 7 through the clamping block 13 to prevent the screw 4 from rotating after the grinding wheel body 15 is clamped, thereby improving the accuracy of the test.
[0034] Embodiment 4
[0035] On the basis of Example 3, in order to ensure that the block 13 is always engaged in the tooth groove of the gear 7 during rotation, a slide groove b11 is opened on the left side of the bottom of the support plate 2, and the inner wall of the slide groove b11 is slidably connected to the limit block 12, and a spring 14 is installed on the left side of the limit block 12, so that the setting of the limit block 12 can prevent the block 13 from being pushed out of the slide groove b11 by the elastic force of the spring 14, and the right side of the limit block 12 is fixedly connected to the left side of the block 13, and the left end of the spring 14 is installed on the inner wall of the slide groove b11, so that the elastic force of the spring 14 can be used to keep the block 13 always engaged in the tooth groove of the gear 7 after rotation.
[0036] During the rotation of the gear 7, since the left side of the clamping block 13 is installed between the right side of the limit block 12, and a spring 14 is installed on the left side of the limit block 12, the elastic force of the spring 14 drives the limit block 12 to slide to the right along the inner wall of the slide groove b11, thereby driving the clamping block 13 to the right to be clamped in the tooth groove of the gear 7, and allowing the clamping block 13 to always be clamped between the tooth groove of the rotated gear 7, thereby locking the position of the screw rod 4 after rotation to prevent it from rotating.
[0037] In actual use, the grinding wheel body 15 is first installed on the right side of the support plate 2, and then the moving block 6 is driven to move downward along the slide groove a5, and the clamping roller 10 is driven to move downward, so as to clamp the grinding wheel body 15. At the same time, rubber blocks 9 are installed on the front and rear sides of the moving block 6, so as to prevent the position of the clamping roller 10 from shifting after the grinding wheel body 15 is clamped, thereby preventing the test results from being affected, thereby facilitating the use of workers. After the adjustment is completed, the worker uses the test fixture body 1 to perform a deflection test on the grinding wheel body 15.
[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
