Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding wheel technology, specifically a balance adjustment structure for mounting grinding wheels in drill bit processing. Background Technology
[0002] The working principle of a grinding wheel machine is based on the grinding principle. A motor drives the grinding wheel to rotate at high speed, and the abrasive grains on the wheel rub against and cut the workpiece surface, achieving grinding, cutting, and polishing. Drill bits will wear down after a period of use, at which point grinding wheel equipment is needed to repair and polish them, ensuring their normal operation.
[0003] However, in the current technology, if the installation angle is off or the fixing screws are loose during the installation process of the grinding wheel, it will cause vibration and eccentricity when the grinding wheel rotates, which will affect the grinding effect. Furthermore, an unbalanced grinding wheel will lead to uneven wear, increase the wear rate of the grinding wheel, and reduce its lifespan. Utility Model Content

The slide groove is equipped with a slider, and the slider is equipped with an adjustment plate. The outer wall of the adjustment plate and the inner wall of the support are both equipped with cavities. The inner wall of the cavity is equipped with a spring and an activation button. The cavity is equipped with a protruding plate, and a protruding rod is equipped on one side of the protruding plate.
[0006] As a preferred embodiment of this utility model, the drive shaft is located on the inner wall of the mounting frame and is rotatably connected to the mounting frame. The grinding wheel is sleeved outside the drive shaft and is coaxially connected to the drive shaft by bolts.
[0007] As a preferred embodiment of this utility model, the bracket is connected to the inner wall of the mounting frame by welding and is located directly above the grinding wheel after installation. The slider is located in the groove and is slidably connected to the inner wall of the groove. One end of the slider extends to the outside and is connected to the adjustment plate. The adjustment plate cooperates with the bracket to wrap around the bottom of the grinding wheel but does not contact it.
[0008] As a preferred embodiment of this utility model, the motor is connected to the outside of the mounting frame by bolts, the output end of the motor is connected to the lead screw by a coupling, and the other end of the lead screw extends into the slide groove and passes through the slider.
[0009] As a preferred embodiment of this utility model, the cavities on the bracket and the adjustment plate are opposite to each other, one end of the convex plate is located inside the cavity and is slidably connected to the inner wall of the cavity, and the other end is pushed out of the cavity by a spring.
[0010] In a preferred embodiment of this invention, the activation button is connected to the inner wall of the cavity and electrically connected to the drive shaft; the protruding rod is connected to the outer wall of the protruding plate by bolts and corresponds to the activation button. Compared with the prior art, the beneficial effects of this utility model are as follows: In response to the problems raised in the background art, this application adopts a positioning component.

[0016] A slider 402 is provided inside the slide groove 401, and an adjusting plate 6 is provided outside the slider 402. The adjusting plate 6 can move within the bracket 4 to adjust the distance between itself and the grinding wheel 3. Both the outer wall of the adjusting plate 6 and the inner wall of the bracket 4 are provided with cavities 7 for positioning the angle of the convex plate 8 when it moves. A spring 701 and an activation button 702 are provided on the inner wall of the cavity 7. The spring 701 is used to support the convex plate 8 and push it out of the cavity 7 to be close to but not in contact with the grinding wheel 3. The convex plate 8 is provided inside the cavity 7. A protruding rod 801 is provided on one side of the convex plate 8. When the angle of the grinding wheel 3 deviates, it will contact and squeeze the convex plate 8, causing the convex plate 8 to retract into the cavity 7.

The angle status of the grinding wheel 3 during operation is monitored, and the machine is stopped and reminded when the angle is tilted.
[0017] In this embodiment, all electrical components are controlled by a conventional controller.
[0018] For an example, please refer to... Figure 1-4The drive shaft 2 is located on the inner wall of the mounting frame 1 and is rotatably connected to the mounting frame 1. The grinding wheel 3 is fitted onto the outside of the drive shaft 2 and is coaxially connected to the drive shaft 2 by bolts. The bracket 4 is welded to the inner wall of the mounting frame 1 and is located directly above the grinding wheel 3 after installation. The slider 402 is located in the slide groove 401 and is slidably connected to the inner wall of the slide groove 401. One end of the slider 402 extends to the outside and is connected to the adjusting plate 6. The adjusting plate 6, in conjunction with the bracket 4, wraps around the bottom of the grinding wheel 3 but does not contact it. The motor 5 is bolted to the mounting frame 1. Externally connected, the output end of the motor 5 is connected to the lead screw 501 via a coupling. The other end of the lead screw 501 extends into the slide groove 401 and passes through the slider 402. The cavity 7 on the bracket 4 and the adjusting plate 6 are opposite to each other. One end of the convex plate 8 is located inside the cavity 7 and is slidably connected to the inner wall of the cavity 7. The other end is pushed out of the cavity 7 by the spring 701.

The slide block 402 slides in the groove 401 through the groove of the lead screw 501 and drives the adjusting plate 6 to move and adjust the distance between the slide block 402 and the grinding wheel 3. When the angle of the grinding wheel 3 deviates during operation, it will abut against the convex plate 8 on the bracket 4 or the adjusting plate 6 and squeeze it to shrink into the cavity 7. At the same time, the convex rod 801 on one side of the convex plate 8 presses the activation button 702 to trigger and control the drive shaft 2 to stop, reminding the operator.
[0019] The working process of this utility model is as follows: First, the grinding wheel 3 is fitted into the drive shaft 2. Then, the PLC controller controls the motor 5 to rotate the lead screw 501. The grooves on the lead screw 501 cause the slider 402 to slide within the groove 401, moving the adjusting plate 6 to adjust the distance between the slider and the grinding wheel 3. If the grinding wheel 3 deviates from its angle during operation, it will abut against the bracket 4 or the protruding plate 8 on the adjusting plate 6, causing it to retract into the cavity 7. Simultaneously, the protruding rod 801 on one side of the protruding plate 8 presses the activation button 702, triggering and stopping the drive shaft 2 to alert the operator. This utility model limits the range of grinding wheel rotation, detects angle deviations, and controls the grinding wheel to stop, thus monitoring the grinding wheel's operation and providing alerts in case of abnormalities, improving the stability of grinding wheel operation.
