Description

Technical Field

[0001] This utility model relates to the field of grinding wheel quality inspection technology, specifically a grinding wheel surface flatness inspection device. Background Technology

[0002] Grinding wheels are widely used in industrial production for grinding and cutting metal or non-metal workpieces. During operation, the grinding wheel rotates at high speed, and its surface flatness directly affects machining accuracy, workpiece surface quality, and operational safety. An uneven grinding wheel generates unbalanced forces during high-speed rotation, easily causing equipment vibration, which not only reduces equipment lifespan but may also cause the grinding wheel to break, posing a safety threat to operators.

[0003] Currently, the existing technology for detecting the surface flatness of grinding wheels mainly involves multiple manual measurements using contact measuring instruments such as dial indicators. This process is cumbersome and prone to significant human error, making it difficult to meet the demand for rapid and accurate testing of grinding wheels in production. Summary of the Invention

The fixed plate is vertically fixed to the upper surface of the testing platform, and the drive motor is mounted on the fixed plate. The output shaft of the drive motor is connected to a grinding wheel to control the rotation of the grinding wheel.

[0008] The testing mechanism, positioned relative to the grinding wheel, includes a testing head, a pressure rod, a sleeve, a pressure spring, and a support plate. The testing head is parallel to the radial direction of the grinding wheel, and its length is no greater than the radius of the grinding wheel. One side of the testing head is connected to the pressure rod, which is installed inside the sleeve and can move horizontally within the sleeve. The sleeve is fixed to one side of the support plate. A pressure spring is provided between the pressure rod and the support plate. A pressure sensor is provided on the surface of the support plate. The flatness of the grinding wheel surface is determined by the force change of the pressure sensor.

[0009] A telescopic assembly, connected to the detection mechanism, is used to control the detection head in the detection mechanism to contact the surface of the grinding wheel for flatness detection;

[0010] A support assembly, connected to the telescopic assembly, is used to support the telescopic assembly.

[0011] As a preferred embodiment of this utility model, the drive assembly further includes a fixed disk, a boss, a screw, and a locking nut. The fixed disk is connected to the output shaft of the drive motor by bolts. The boss is integrally connected to one end of the fixed disk, and a screw is connected to one end of the boss. The outer diameter of the boss is larger than the center hole size of the grinding wheel. The grinding wheel is sleeved on the outside of the screw, and one end of the grinding wheel is in contact with the boss. The locking nut is threaded onto the screw to fix the grinding wheel.

[0012] As a preferred embodiment of this utility model, one end of the detection head is a flat surface and the other end is a conical protrusion, and the contact end between the detection head and the surface of the grinding wheel is the conical protrusion end.

[0013] As a preferred embodiment of this invention, the detection head and the support plate do not interfere with the locking nut.

[0014] As a preferred embodiment of this utility model, the telescopic assembly includes an electric telescopic rod and a connecting plate.

[0016] As a preferred embodiment of the present invention, the support assembly further includes a base plate and spring columns.

[0026] 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 (for ease of description and understanding, hereinafter referred to as...). Figure 3 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a grinding wheel surface flatness detection device, including a detection platform 1, a drive component 2, a detection mechanism 4, a telescopic component 5, a support component 6, and a control display 7;

[0028] The drive assembly 2 includes a fixed plate 21, a drive motor 22, a fixed disk 23, a boss 24, a screw 25, and a locking nut 26. The fixed plate 21 is vertically fixed on the upper surface of the detection platform 1, and the drive motor 22 is mounted on the fixed plate 21.

[0029] In order to quickly fix the grinding wheel, the output shaft of the drive motor 22 is connected to the fixed plate 23 by bolts. The boss 24 is integrally connected to one end of the fixed plate 23. One end of the boss 24 is connected to the screw 25. The outer diameter of the boss 24 is larger than the center hole of the grinding wheel 3. The grinding wheel 3 is sleeved on the outside of the screw 25 and one end of the grinding wheel 3 is in contact with the boss 24. The locking nut 26 is threaded on the screw 25 to achieve a firm fixation of the grinding wheel 3. Under the action of the drive motor 22, the grinding wheel 3 is driven to rotate.

[0030] The detection mechanism 4 includes a detection head 41, a pressure rod 42, a sleeve 43, a pressure spring 44, and a support plate 45. The detection head 41 is parallel to the radial direction of the grinding wheel 3 and its height position corresponds to that of the grinding wheel 3. The length of the detection head 41 is not greater than the radius of the grinding wheel 3. When the detection head 41 contacts the grinding wheel 3, it ensures that the detection head 41 can fully contact the radial end face of the grinding wheel 3.

[0031] One side of the detection head 41 is connected to the pressure rod 42, which is installed inside the sleeve 43 and can move horizontally within the sleeve 43. The sleeve 43 is fixed to one side of the support plate 45. A pressure spring 44 is provided between the pressure rod 42 and the support plate 45. A pressure sensor 46 is provided on the surface of the support plate 45. After the detection head 41 contacts the end face of the grinding wheel 3, the grinding wheel 3 rotates. If there are defects such as protrusions on the surface of the grinding wheel 3, the detection head 41 will be compressed by the pressure rod 42, thereby causing the pressure signal received by the pressure sensor 46 to change. The change in force received by the pressure sensor 46 is used to determine whether the surface flatness of the grinding wheel 3 is qualified.

[0032] The telescopic assembly 5 includes an electric telescopic rod 51 and a connecting plate 52. The connecting plate 52 is symmetrically fixed at the upper and lower ends of the support plate 45 in the detection mechanism 4. The telescopic end of the electric telescopic rod 51 is connected to one side of the connecting plate 52. Under the action of the electric telescopic rod 51, the detection head 41 in the detection mechanism 4 is controlled to contact the surface of the grinding wheel 3 to perform flatness detection.

[0033] The support assembly 6 includes a U-shaped frame 61, which is connected to the telescopic assembly 5 and is used to support the telescopic assembly 5;

[0034] The detection platform 1 is equipped with a control display 7, which has both control and display functions. The output end of the control display 7 is electrically connected to the input end of the drive motor 22 and the electric telescopic rod 51, respectively. The control display 7 has corresponding control buttons, which can control the operation of the drive motor 22 and the electric telescopic rod 51. The input end of the control display 7 is electrically connected to the output end of the pressure sensor 46, which is used to display the fluctuation curve of the pressure signal.

[0035] To increase the tightness of the contact between the detection head 41 and the surface of the grinding wheel 3, one end of the detection head 41 is a flat surface and the other end is a conical protrusion. The contact end between the detection head 41 and the surface of the grinding wheel 3 is the conical protrusion end, so that there is no gap between the detection head 41 and the surface of the grinding wheel 3.

[0036] To avoid interference between the detection head 41 and the components in the drive assembly 2 during movement, the detection head 41 and the support plate 45 do not interfere with the locking nut 26 in the longitudinal position.

[0037] To ensure the stability and straightness of the detection head 41 during horizontal movement, the telescopic assembly 5 also includes a slide rod 53 and a sliding sleeve 54. There are two slide rods 53. The opening of the U-shaped frame 61 faces the detection mechanism 4. The two slide rods 53 are fixed horizontally at the upper and lower ends of the U-shaped frame 61, respectively. The end of the connecting plate 52 is slidably connected to the outer side of the slide rod 53. A sliding sleeve 54 is provided between the connecting plate 52 and the slide rod 53. By providing the sliding sleeve 54, it can be ensured that the connecting plate 52 remains stable during the sliding along the slide rod 53.

[0038] In order to improve the seismic performance of the entire testing device and avoid the impact of vibration on the accuracy of the test results during the testing process, the support assembly 6 also includes a base plate 62 and spring columns 63. The base plate 62 is fixed on the upper surface of the testing platform 1, and multiple spring columns 63 are evenly distributed between the base plate 62 and the U-shaped frame 61.

[0039] In use: The grinding wheel 3 to be tested is put into the outside of the screw 25, and then the locking nut 26 is tightened to fix the grinding wheel 3. At this time, the electric telescopic rod 51 is extended by the control display 7 so that the detection head 41 contacts the end face of the grinding wheel 3 in the radial direction. At this time, the pressure signal received by the pressure sensor 46 is displayed as zero on the control display 7. The drive motor 22 is turned on, and the output shaft of the drive motor 22 drives the grinding wheel to rotate. The detection head 41 detects the flatness of the entire surface of the grinding wheel 3.

[0040] When the surface of the grinding wheel 3 is uneven, the pressure of the pressure spring 44 on the pressure rod 42 of the detection head 41 changes, and the pressure signal received by the pressure sensor 46 changes, resulting in pressure curve fluctuation on the control display 7. Based on the amplitude of the fluctuation curve, it can be determined whether the flatness of the grinding wheel 3 meets the requirements.

[0041] If the pressure fluctuation curve on the control display 7 remains relatively stable, it indicates that the flatness of the grinding wheel 3 surface meets the quality requirements.

[0042] The parts of the utility model not described in detail are prior art. Although embodiments of the utility model 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 utility model. The scope of the utility model is defined by the appended claims and their equivalents.
