Abstract

This utility model provides a quick-clamp mechanism for a grinding wheel used in dynamic balancing tests. The mechanism includes a device body with a vertical plate mounted on the top surface near the edge. A rotary motor is mounted on the outer surface of the vertical plate. During operation, the operator attaches the grinding wheel to the outside of the mounting cylinder. Then, the operator drives the extrusion threaded cylinder to rotate via a handwheel, causing the extrusion threaded cylinder to move around the circumference of the mounting cylinder. During this movement, the extrusion threaded cylinder drives the moving ring to move. Then, the cooperation of a first mounting seat, a second mounting seat, a first extrusion rod, a second extrusion rod, an arc-shaped extrusion rod, and a third mounting seat causes the arc-shaped extrusion plate to move outward via the first and second extrusion rods, thus pressing and fixing the inner wall of the grinding wheel. This completes the fixing of the grinding wheel, and the dynamic balance of the grinding wheel can then be tested. This method is simple to operate and improves its flexibility and application range.

Description

Technical Field

[0001] This utility model relates to the field of grinding wheel testing technology, and in particular to a quick-clamp mechanism for grinding wheels used in dynamic balancing testing. Background Technology

[0002] Grinding wheels are one of the most important types of abrasive tools in grinding processes. They are porous bodies made by adding a binder to abrasive particles, followed by pressing, drying, and firing. Due to differences in abrasive particles, binders, and manufacturing processes, the characteristics of grinding wheels vary greatly, thus significantly impacting the processing quality, productivity, and economics of grinding. During the manufacturing process, because the abrasive particles are not perfectly uniformly distributed, some areas of the finished grinding wheel are lighter than others, resulting in an imbalance. Therefore, the balance of the grinding wheel must be checked before it leaves the factory.

[0003] The utility model with publication number CN206632878U proposes a grinding wheel balancing detection device, which mainly includes a base, a support rod, and two parallel horizontal rods. A rotating shaft is placed on the horizontal rods. The support rod is vertically fixed on the base. A marking mechanism is provided on the upper surface of the base between the horizontal rods. The marking mechanism includes a vertical lifting component and a coloring end set on the upper end of the vertical lifting component to realize the function of detecting instability of the center of gravity. In use, the rotating shaft needs to be connected and fixed to the inner hole of the grinding wheel. In actual use, the inner diameter of different models of grinding wheels is different, and the rotating shaft is difficult to meet the fixing requirements, resulting in poor applicability of the device.

[0004] Therefore, it is necessary to provide a quick-clamp mechanism for grinding wheels used in dynamic balancing tests to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a quick-clamp mechanism for a grinding wheel used in dynamic balancing testing, which solves the problems in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides a quick-clamp mechanism for dynamic balancing testing grinding wheels, comprising a device body. A vertical plate is vertically mounted on the top surface of the device body near the edge. A rotary motor is mounted on the outer surface of the vertical plate. The output end of the rotary motor passes through the surface of the vertical plate and is connected to a drive shaft. A mounting cylinder is fixed to one end of the drive shaft. A clamping mechanism is mounted on the circumferential side of the mounting cylinder. An external thread is provided on the circumferential side of the mounting cylinder, and a connecting extrusion threaded cylinder is spirally formed on the surface of the external thread. By using the mounting cylinder, clamping mechanism, extrusion threaded cylinder, and handwheel in cooperation, it is convenient to fix grinding wheels of different specifications, making operation easier. The worker attaches the grinding wheel to the outside of the mounting cylinder. Then, the worker drives the extrusion threaded cylinder to rotate using a handwheel, causing the extrusion threaded cylinder to move around the circumference of the mounting cylinder. During the movement of the extrusion threaded cylinder, it drives the moving ring to move. Then, with the cooperation of the first mounting seat, the second mounting seat, the first extrusion rod, the second extrusion rod, the arc-shaped extrusion rod, and the third mounting seat, the arc-shaped extrusion plate is moved outward by the first and second extrusion rods. After that, the inner wall of the grinding wheel is extruded and fixed, thus completing the fixing of the grinding wheel. Then, the dynamic balance of the grinding wheel is checked. This method is simple to operate and facilitates its flexibility and application range.

[0007] Preferably, the clamping mechanism includes a first mounting seat, a second mounting seat, an arc-shaped extrusion plate, and a moving ring. The first mounting seat is mounted on the circumferential side of the mounting cylinder. A third mounting seat is provided on the bottom surface of the arc-shaped extrusion plate. The second mounting seat is mounted on the circumferential side of the moving ring. A first extrusion rod and a second extrusion rod are movably mounted between the first mounting seat and the third mounting seat and between the second mounting seat and the third mounting seat.

[0008] Preferably, a slide rail is provided on the circumferential side of the mounting cylinder, and a slider is provided on the inner wall of the moving ring. The slider is slidably connected to the slide rail, and the width of the slider is equal to the inner width of the slide rail. By providing the slide rail, it is easy to allow the slider to move. Moreover, the cooperation between the slider and the slide rail makes it easy to ensure that the moving ring moves back and forth on the surface of the mounting cylinder, which facilitates the synchronous driving of multiple clamping mechanisms and the fixing of the grinding wheel. Furthermore, the moving ring facilitates the connection of multiple clamping mechanisms and improves the overall stability.

[0009] Preferably, multiple clamping mechanisms are provided, and the multiple clamping mechanisms are installed at equal intervals around the side of the mounting cylinder. By providing multiple clamping mechanisms, the stability of the grinding wheel extrusion is improved, which facilitates subsequent processing.

[0010] Preferably, a handwheel is provided at one end of the extrusion threaded cylinder, which facilitates the rotation of the extrusion threaded cylinder.

[0011] Preferably, a controller is installed on the outer surface of the device body, which facilitates the control of the electrical components inside the device body.

[0012] Compared with related technologies, the quick-clamp mechanism for dynamic balancing testing of the grinding wheel provided by this utility model has the following advantages:

[0013] Compared with existing technologies, the quick-clamp mechanism for grinding wheels used in dynamic balancing testing, through the coordinated use of an installation cylinder, clamping mechanism, extrusion threaded cylinder, and handwheel, facilitates the fixing of grinding wheels of different specifications. During operation, the operator places the grinding wheel onto the outside of the installation cylinder, and then rotates the extrusion threaded cylinder using the handwheel, causing the extrusion threaded cylinder to move around the circumference of the installation cylinder. During this movement, the moving ring moves, and then the coordinated use of the first mounting seat, second mounting seat, first extrusion rod, second extrusion rod, arc-shaped extrusion rod, and third mounting seat forces the grinding wheel through the first extrusion... The pressure rod and the second extrusion rod move the arc-shaped extrusion plate outward, and then extrude and fix it to the inner wall of the grinding wheel, thus completing the fixation of the grinding wheel. Then, the dynamic balance of the grinding wheel can be checked. This method is simple to operate and can improve its flexibility and application range. By setting the slide, it is easy to allow the slider to move. Moreover, the cooperation between the slider and the slide makes it easy to ensure that the moving ring moves back and forth on the surface of the mounting cylinder, which facilitates the synchronous driving of multiple clamping mechanisms and the fixation of the grinding wheel. In addition, the setting of the moving ring facilitates the connection of multiple clamping mechanisms and improves the overall stability.

The output end of the rotary motor 4 passes through the surface of the vertical plate 2 and is connected to a drive shaft 5. A mounting cylinder 6 is fixed to one end of the drive shaft 5. A clamping mechanism is mounted on the circumferential side of the mounting cylinder 6. An external thread 16 is provided on the circumferential side of the mounting cylinder 6. A connecting extrusion threaded cylinder 12 is spirally connected to the surface of the external thread 16. By using the mounting cylinder 6, clamping mechanism, extrusion threaded cylinder 12, and handwheel 18 in cooperation, it is convenient to fix grinding wheels of different specifications, so that during operation, the operator can easily clamp the grinding wheel. After being connected to the outside of the mounting cylinder 6, the operator drives the extrusion thread cylinder 12 to rotate via the handwheel 18, causing the extrusion thread cylinder 12 to move around the side of the mounting cylinder 6. During the movement of the extrusion thread cylinder 12, the moving ring 13 is also moved. Then, with the cooperation of the first mounting seat 7, the second mounting seat 11, the first extrusion rod 8, the second extrusion rod 10, the arc-shaped extrusion rod, and the third mounting seat 14, the arc-shaped extrusion plate 9 is moved outward by the first extrusion rod 8 and the second extrusion rod 10, and then the inner wall of the grinding wheel is extruded and fixed, thus completing the fixing of the grinding wheel.

Then, the inner wall of the grinding wheel is pressed and fixed, thus completing the fixing of the grinding wheel. Then, the dynamic balance of the grinding wheel is checked. This method is simple to operate and can improve its flexibility and application range. By setting the slide 15, it is easy to allow the slider 17 to move. Moreover, the cooperation between the slider 17 and the slide 15 can ensure that the moving ring 13 moves back and forth on the surface of the mounting cylinder 6, which can facilitate the synchronous driving of multiple clamping mechanisms and facilitate the fixing of the grinding wheel. In addition, the setting of the moving ring 13 can facilitate the connection of multiple clamping mechanisms and improve its overall stability.

The pressure rod 8 and the second extrusion rod 10 move the arc-shaped extrusion plate 9 outward, and then extrude and fix it to the inner wall of the grinding wheel, thus completing the fixation of the grinding wheel. Then, the dynamic balance of the grinding wheel can be checked. This method is simple to operate and can improve its flexibility and application range.
