Description

Technical Field

[0001] This application relates to the field of grinding machine technology, and in particular to a grinding machine that is easy to maintain. Background Technology

[0002] A grinding wheel dressing machine is a specialized piece of equipment used to dress the surface of a grinding wheel and restore its geometry and grinding performance.

[0003] A search revealed that Chinese Patent Publication No. CN104385138B discloses a grinding wheel dressing machine, which includes a frame, a bearing seat on the frame to support the rotation of the grinding wheel, and a dressing disc that contacts the circumference of the grinding wheel. The frame is provided with a transmission mechanism to drive the rotation of the grinding wheel and an axial lateral movement mechanism to drive the dressing disc to move along a direction parallel to the axis of the grinding wheel. The axis of the dressing disc is at an acute angle to the axis of the grinding wheel.

[0004] The existing grinding machine uses nuts to fasten the grinding wheel to the output shaft. When performing maintenance, the nuts need to be removed, repaired, and then reinstalled. This operation is cumbersome, time-consuming, and labor-intensive. Moreover, after repeated maintenance, the threads are prone to stripping. Therefore, maintenance is neither convenient nor quick.

[0005] Therefore, this application proposes a grinding machine that is easy to maintain. Utility Model Content

[0006] In order to solve the problems mentioned in the background art, this application provides a grinding machine that is easy to maintain.

[0007] This application provides a maintenance-friendly grinding machine, employing the following technical solution: It includes a machine body, with a rotating shaft at the output end of the machine body. A limiting cylinder is fixedly connected to the front end of the rotating shaft. A grinding wheel is sleeved on the outer wall of the limiting cylinder. The limiting cylinder is a hollow cylinder, and a limiting assembly for quick installation and removal of the grinding wheel is provided inside the limiting cylinder cavity. The limiting assembly includes two sets of stop block units, a main shaft, and an adjusting pull part. Each stop block unit includes a rectangular mounting plate, a triangular block, and a movable block. The movable block is fixedly installed at one end of the rectangular mounting plate. The main shaft movably passes through the two sets of movable blocks, and the main shaft is in transmission cooperation with the two sets of movable blocks. The adjusting pull part includes a gear and a rack.

[0008] The above solution involves adjusting the pulling part to drive the spindle to rotate. The rotation of the spindle causes the two sets of stop blocks to move away from each other and come into contact with the grinding wheel, thereby limiting and fixing the grinding wheel. This method makes installation and disassembly more convenient.

[0009] Optionally, the outer wall of the limiting cylinder is provided with movable grooves on both sides, the triangular block moves through the corresponding movable groove, and the triangular block is fixedly connected to the rectangular mounting plate.

[0010] With the above scheme, movable grooves are opened on both sides of the outer wall of the limiting cylinder, and the triangular block moves through the corresponding movable groove, with the inclined surface of the triangular block contacting the grinding wheel.

[0011] Optionally, the two sets of stop block units are symmetrical to each other, and a limit guide frame is fixedly installed inside the limit cylinder cavity, with the two sets of stop block units movably engaged in the limit guide frame cavity.

[0012] The above scheme involves setting two sets of stop block units in a symmetrical state, fixing a limiting guide frame inside the limiting cylinder cavity, and having the two sets of stop block units movably engage within the limiting guide frame cavity, thereby allowing the stop block units to move along the limiting guide frame.

[0013] Optionally, the main shaft is movably installed in the limiting cylinder cavity, and a set of reverse threads are provided on the outer wall surface of the main shaft. The main shaft is threadedly connected to two sets of moving blocks, and the two sets of moving blocks are located at both ends of the main shaft.

[0014] The above scheme allows the rotation of the main shaft to bring the two sets of moving blocks closer to or further apart.

[0015] Optionally, the rack engages with the gear, a rectangular guide strip is fixedly connected to the top of the rack, a groove is provided in the cavity of the limiting guide frame, and the rectangular guide strip is movably engaged in the corresponding groove.

[0016] With the above scheme, the rack and gear mesh movably, the rack moves and the gear rotates, and the rectangular guide bar is movably engaged in the corresponding groove to guide the movement of the rectangular guide bar.

[0017] Optionally, the adjusting pull part further includes a rectangular plate and a connecting column, wherein the rectangular plate is fixedly connected to the rectangular guide strip and the rack, and the connecting column is fixedly connected to the rectangular plate.

[0018] The above scheme involves setting up a rectangular plate that is fixedly connected to a rectangular guide strip and a rack, and the movement of the connecting column causes the rectangular plate to move synchronously.

[0019] Optionally, the end of the connecting column away from the rectangular plate can be movably inserted through the limiting cylinder and fixedly connected to the cylindrical plate. A compression spring is sleeved on the outer wall of the connecting column, and a handle is fixedly installed on the outer wall of the cylindrical plate.

[0020] The above scheme uses a handle to move the cylindrical plate and a connecting column to apply force to the rectangular plate, ensuring the device works normally.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] 1. This utility model features a limiting cylinder fixedly installed on the rotating shaft at the output end of the machine body. A limiting component for quick installation and removal of the grinding wheel is provided inside the limiting cylinder cavity. By adjusting the pulling part, the main shaft is rotated. The rotation of the main shaft causes the two sets of stop blocks to move away from each other and contact the grinding wheel, thereby limiting and fixing the grinding wheel. This method makes installation and removal more convenient and facilitates subsequent maintenance by installing and removing the grinding wheel.

[0023] 2. This utility model sets two sets of stop block units in a symmetrical state, and a limiting guide frame is fixedly installed in the limiting cylinder cavity. The two sets of stop block units are movably engaged in the limiting guide frame cavity, so that the stop block units move along the limiting guide frame. At the same time, the limiting guide frame isolates external impurities and limits the cylinder cavity.

[0024] 3. This utility model is fixedly connected to a rectangular plate by a connecting column. When maintenance personnel pull the rectangular plate and the rack to move synchronously, the two sets of stop block units approach each other and enter the limiting cylinder cavity. At this time, the grinding wheel can be easily removed. By setting a compression spring on the outer wall of the connecting column, a pushing force is provided to the rectangular plate to ensure the normal operation of the device. After the maintenance personnel release the handle, the compression spring gives force to the rectangular plate, causing the two sets of stop block units to move away from each other and extend out of the limiting cylinder cavity.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a grinding machine that is easy to maintain. For example... Figure 1 As shown, the machine includes a body 10, with a rotating shaft 12 at the output end of the body 10. A limiting cylinder 14 is fixedly connected to the front end of the rotating shaft 12. A grinding wheel 11 is sleeved on the outer wall of the limiting cylinder 14. The limiting cylinder 14 is a hollow cylinder. A limiting component for quick installation and removal of the grinding wheel 11 is provided inside the cavity of the limiting cylinder 14. The limiting component includes two sets of stop block units 13, a main shaft 16, and an adjusting pull part. The stop block unit 13 includes a rectangular mounting plate 21, a triangular block 22, and a moving block 23. The moving block 23 is fixedly installed at one end of the rectangular mounting plate 21. The main shaft 16 movably passes through the two sets of moving blocks 23. The main shaft 16 is in transmission cooperation with the two sets of moving blocks 23. The adjusting pull part includes a gear 17 and a rack 18.

[0034] By fixing a limiting cylinder 14 on the rotating shaft 12 at the output end of the machine body 10, and by setting a limiting component in the cavity of the limiting cylinder 14 for quick installation and removal of the grinding wheel 11, the main shaft 16 is rotated by adjusting the pulling part. The rotation of the main shaft 16 causes the two sets of stop block units 13 to move away from each other and contact the grinding wheel 11, thereby limiting and fixing the grinding wheel 11. This method makes installation and removal more convenient and facilitates the installation and removal of the grinding wheel 11 for later maintenance.

[0035] Please see Figure 2 The outer wall of the limiting cylinder 14 is provided with movable grooves on both sides, and the triangular block 22 moves through the corresponding movable groove. The triangular block 22 is fixedly connected to the rectangular mounting plate 21.

[0036] Movable grooves are provided on both sides of the outer wall of the limiting cylinder 14. Triangular blocks 22 move through the corresponding movable grooves. The inclined surface of the triangular blocks 22 contacts the grinding wheel 11. The position of the triangular blocks 22 is adjusted until the grinding wheel 11 is limited and fixed.

[0037] Please see Figure 3 The two sets of stop block units 13 are symmetrical to each other. The limit guide frame 15 is fixedly installed in the cavity of the limit cylinder 14, and the two sets of stop block units 13 are movably engaged in the cavity of the limit guide frame 15.

[0038] By setting two sets of stop block units 13 in a symmetrical state, and fixing the limiting guide frame 15 inside the cavity of the limiting cylinder 14, the two sets of stop block units 13 are movably engaged in the cavity of the limiting guide frame 15, so that the stop block units 13 move along the limiting guide frame 15, while the limiting guide frame 15 isolates external impurities from entering the cavity of the limiting cylinder 14.

[0039] The main shaft 16 is movably installed inside the cavity of the limiting cylinder 14. A set of reverse threads is formed on the outer wall of the main shaft 16. The main shaft 16 is threadedly connected to two sets of moving blocks 23, which are located at both ends of the main shaft 16. The rack 18 is movably meshed with the gear 17. A rectangular guide strip 19 is fixedly connected to the top of the rack 18. A groove is formed inside the cavity of the limiting guide frame 15, and the rectangular guide strip 19 is movably engaged in the corresponding groove.

[0040] The main shaft 16 is movably installed in the cavity of the limiting cylinder 14. The main shaft 16 is fixedly connected to the through gear 17. A set of reverse threads is opened on the outer wall of the main shaft 16. The main shaft 16 is threadedly connected to the two sets of moving blocks 23. The rack 18 is movably meshed with the gear 17, so that the rack 18 moves to drive the gear 17 to drive the main shaft 16 to rotate. The rotation of the main shaft 16 causes the two sets of moving blocks 23 to move closer or further away from each other. A rectangular guide bar 19 is fixedly connected to the top of the rack 18. A groove is opened in the cavity of the limiting guide frame 15. The rectangular guide bar 19 is movably engaged in the corresponding groove, which improves the stability of the device and guides the movement of the rectangular guide bar 19.

[0041] Please see Figure 5 The adjusting pull part also includes a rectangular plate 20 and a connecting post 26. The rectangular plate 20 is fixedly connected to the rectangular guide strip 19 and the rack 18, and the connecting post 26 is fixedly connected to the rectangular plate 20. The end of the connecting post 26 away from the rectangular plate 20 movably passes through the limiting cylinder 14 and is fixedly connected to the cylindrical plate 24. A compression spring 27 is sleeved on the outer wall of the connecting post 26, and a handle 25 is fixedly installed on the outer wall of the cylindrical plate 24.

[0042] During operation, maintenance personnel pull the cylindrical plate 24 and the connecting column 26 through the handle 25. The connecting column 26 is fixedly connected to the rectangular plate 20, thereby pulling the rectangular plate 20 and the rack 18 to move. During this process, the two sets of stop block units 13 approach each other and enter the cavity of the limiting cylinder 14. At this time, the grinding wheel 11 can be easily removed. By setting the compression spring 27 on the outer wall of the connecting column 26, a pushing force is provided to the rectangular plate 20 to ensure the normal operation of the device. After the maintenance personnel release the handle 25, the compression spring 27 gives the rectangular plate 20 a force that causes the two sets of stop block units 13 to move away from each other and extend out of the cavity of the limiting cylinder 14.

[0043] The implementation principle of the maintenance-friendly grinding machine in this application embodiment is as follows: The maintenance personnel pull the cylindrical plate 24 and the connecting column 26 through the handle 25. The connecting column 26 is fixedly connected to the rectangular plate 20, thereby pulling the rectangular plate 20 and the rack 18 to move. During this process, the two sets of stop block units 13 approach each other and enter the cavity of the limiting cylinder 14. At this time, the grinding wheel 11 can be easily removed. By setting the compression spring 27 on the outer wall of the connecting column 26, a pushing force is provided to the rectangular plate 20 to ensure the normal operation of the device. After the maintenance personnel release the handle 25, the compression spring 27 gives the rectangular plate 20 a force that causes the two sets of stop block units 13 to move away from each other and extend out of the cavity of the limiting cylinder 14. The two sets of stop block units 13 contact the grinding wheel 11 to limit and fix the grinding wheel 11. The installation and disassembly are more convenient in this way, and it is convenient to install and disassemble the grinding wheel 11 for later maintenance.

[0044] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
