Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, specifically a QPQ benchtop grinding machine with a disc changing structure. Background Technology

[0002] In the QPQ process, benchtop grinders are indispensable auxiliary equipment, mainly used for grinding and finishing workpieces before processing and for surface polishing of processed workpieces. Because the grinding wheel surface suffers severe wear due to continuous friction with the workpiece during prolonged high-speed operation, it not only affects grinding accuracy and efficiency but may also cause safety hazards due to wheel imbalance. Therefore, regular replacement of the grinding wheel is necessary. However, existing benchtop grinders require disassembling multiple sets of bolts on the external protective shell before replacing the grinding wheel. After removing the protective shell cover, tools are needed to unscrew the nuts securing the grinding wheel. This entire process is cumbersome and time-consuming. Especially in QPQ production lines, frequent wheel replacements severely impact the continuous operating efficiency of the equipment, increase labor costs, and the repeated disassembly of bolts and nuts can lead to thread wear, reducing the equipment's lifespan.

[0003] Therefore, this utility model provides a QPQ benchtop grinding machine with a blade changing structure to solve the above problems. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] This invention provides a QPQ benchtop grinding machine with a blade changing structure, aiming to solve the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A QPQ benchtop grinding machine with a grinding wheel changing structure includes a benchtop grinding machine body, with protective shells fixed at both ends of the benchtop grinding machine body. First limiting members are fixed to the outer surfaces of the output shafts at both ends of the benchtop grinding machine body, and grinding wheels are sleeved on the outer surfaces of the output shafts. The machine also includes:

[0009] The disassembly and assembly components, located on the protective housing, are used for disassembling and installing the grinding wheel.

[0010] The assembly and disassembly components include a cover plate fitted onto one side of the protective shell. A second limiting component is fitted in the middle of the cover plate with a bearing. A fixing component is fixed to the end of the output shaft of the bench grinder. Several sets of fixing shafts are fixed to one side of the cover plate. The outer surface of the fixing shafts is provided with slots. Several sets of sliding grooves are provided to one side of the protective shell. A fixing rod is fixed inside the sliding groove. A limiting plate and a return spring are fitted onto the outer surface of the fixing rod. An arc-shaped component is fixed to the outer periphery of the limiting plate.

[0011] As a preferred technical solution of this application, the fixing member is hexagonal, and the second limiting member is sleeved on the outer periphery of the fixing member.

[0012] As a preferred technical solution of this application, the second limiting member cooperates with the first limiting member to clamp and position the grinding wheel.

[0013] As a preferred technical solution of this application, the end of the fixed shaft passes through the protective shell and is sleeved with the protective shell.

[0014] As a preferred technical solution of this application, the limiting plate engages with the fixed shaft through the slot, and when the limiting plate engages with the fixed shaft, the second limiting member squeezes one side of the grinding wheel.

[0015] As a preferred technical solution of this application, the reset spring is elastically supported between the slide groove and the limiting plate.

[0016] As a preferred technical solution of this application, a paddle is fixed on the outer surface of the arc-shaped component, and the outer surface of the paddle is covered with rubber.

[0017] (III) Beneficial Effects

[0018] This application utilizes a lever to release the engagement between the limiting plate and the slot on the fixed shaft. Then, pulling the cover plate moves the second limiting component away from the grinding wheel, allowing the old grinding wheel to be easily removed. When installing a new grinding wheel, pushing the cover plate causes the second and first limiting components to clamp the new grinding wheel. Releasing the lever completes the fixing process. The entire process is fast and efficient, significantly reducing the difficulty and time cost of changing grinding wheels. It completely solves the cumbersome problem of disassembling multiple sets of bolts and nuts when changing grinding wheels in traditional grinding machines, making grinding wheel replacement simple and easy.

[0025] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. The present utility model provides a QPQ processing benchtop grinding wheel machine with a blade changing structure, such as... Figure 1-5 As shown, the QPQ processing benchtop grinder with a changing disc structure includes a benchtop grinder body 1, which serves as the core supporting component of the equipment and provides a stable mounting foundation for the entire grinder.

[0026] Specifically, protective shells 2 are fixed to both ends of the bench grinder body 1. These shells effectively prevent debris from flying during operation, providing safety protection for the operator. First limiting members 3 are fixed to the outer surfaces of the output shafts at both ends of the bench grinder body 1. Grinding wheels 4 are fitted onto the outer surfaces of the output shafts. The first limiting members 3 provide initial restraint on the grinding wheels 4, preventing excessive shaking during operation. A disassembly assembly is located on the protective shell 2 and is a key structure for quick replacement of the grinding wheels 4. This assembly includes a cover plate 5, which is fitted onto one side of the protective shell 2. A second limiting member 7 is mounted in the middle of the cover plate 5 in conjunction with a bearing 6. The bearing 6 allows the second limiting member 7 to rotate flexibly relative to the cover plate 5.

[0027] Specifically, a fixing member 8 is fixed to the end of the output shaft of the bench grinder body 1. The fixing member 8 is hexagonal, and the second limiting member 7 is sleeved on the outer periphery of the fixing member 8. This hexagonal structure design can ensure stable power transmission between the second limiting member 7 and the fixing member 8, and also provides a convenient positioning structure for subsequent disassembly and installation.

[0028] A number of fixed shafts 9 are fixed on one side of the cover plate 5. The outer surface of the fixed shaft 9 is provided with a slot 16. A number of sliding grooves 10 are provided on one side of the protective shell 2. The end of the fixed shaft 9 passes through the protective shell 2 and is sleeved with the protective shell 2. The fixed shaft 9 can move to a certain extent within the range of the sliding groove 10.

[0029] Specifically, a fixing rod 11 is fixed inside the slide groove 10. A limiting plate 12 and a return spring 13 are sleeved on the outer surface of the fixing rod 11. The return spring 13 is elastically supported between the slide groove 10 and the limiting plate 12. When the limiting plate 12 is moved by an external force, the return spring 13 will undergo elastic deformation. After the external force disappears, it can push the limiting plate 12 back to its initial position.

[0030] An arc-shaped part 14 is fixed to the outer periphery of the limiting plate 12. A paddle 15 is fixed to the outer surface of the arc-shaped part 14. The outer surface of the paddle 15 is covered with rubber. The rubber material can increase the friction when the operator moves the paddle 15, and at the same time improve the comfort of operation.

[0031] In the working state, the second limiting member 7, together with the first limiting member 3, clamps and positions the grinding wheel 4 to ensure that the grinding wheel 4 will not undergo axial displacement during high-speed rotation, thus ensuring the normal operation of the grinding machine. The fixed shaft 9, together with the slot 16, engages with the limiting plate 12. When the limiting plate 12 engages with the fixed shaft 9, the second limiting member 7 applies pressure to one side of the grinding wheel 4, further enhancing the stability of the grinding wheel 4 installation.

[0032] Specifically, when the grinding wheel 4 needs to be replaced, the operator moves the lever 15 to move the arc-shaped part 14 and the limiting plate 12 along the fixed rod 11. At this time, the return spring 13 is compressed, causing the limiting plate 12 to move and disengage from the slot 16 on the fixed shaft 9, thus releasing the limitation on the fixed shaft 9. Subsequently, the operator can pull the cover plate 5 to move the fixed shaft 9 along the slide groove 10, thereby moving the second limiting part 7 away from the grinding wheel 4, releasing the clamping of the second limiting part 7 and the first limiting part 3 on the grinding wheel 4. At this time, the old grinding wheel 4 can be removed from the output shaft.

[0033] When installing a new grinding wheel 4, place the new grinding wheel 4 onto the output shaft, ensuring one side is in contact with the first limiting member 3. Then, push the cover plate 5 to move the fixed shaft 9 in the opposite direction along the slide groove 10. The second limiting member 7 gradually approaches the grinding wheel 4. When the second limiting member 7 contacts the grinding wheel 4 and forms a certain amount of pressure, release the lever 15. Under the elastic force of the return spring 13, the limiting plate 12 resets and re-engages with the slot 16 on the fixed shaft 9, completing the limiting of the fixed shaft 9. This allows the second limiting member 7 and the first limiting member 3 to jointly clamp and fix the new grinding wheel 4, thus completing the replacement operation of the grinding wheel 4.

[0034] The design of the above-mentioned disassembly and assembly components enables the quick disassembly and installation of the grinding wheel 4, making the operation simple and fast and effectively improving the efficiency of equipment maintenance.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
