Description

Technical Field

[0001] The utility model belongs to the technical field of polishing wheels, in particular to a polishing wheel which is easy to disassemble. Background Art

[0002] Polishing wheels are used for polishing the surface of workpieces and coatings. Polishing wheels are divided into: polishing cloth wheels, hemp wheels, nylon wheels, wiring wheels, wind wheels, wool wheels, etc. Polishing wheels are often needed for polishing during metal processing, and polishing is divided into coarse grinding, fine grinding and fine grinding, so polishing wheels need to be replaced frequently. The existing polishing device is relatively cumbersome when replacing the polishing wheel, and the fixing stability after replacement is poor, which will affect the polishing accuracy.

[0005] Preferably, an inclined pushing groove is provided on the side wall of the clamping plate, a pushing plate is slidably arranged in the pushing groove, a threaded rod is rotatably provided on the top wall of the support frame, and the threaded rod and the pushing plate are threadedly connected.

[0006] Preferably, the push plate is arranged in an isosceles trapezoidal structure, and the support frame is arranged in a "T"-shaped structure.

[0007] Preferably, the diameter of the support block located in the mounting hole is the same as that of the mounting hole, and the support block is close to the rear side of the polishing wheel and the diameter of the side close to the rotating shaft is larger than the mounting hole, so as to limit the polishing wheel.

[0008] Preferably, the longitudinal section of the mounting groove is an "L"-shaped structure.

[0009] Preferably, a rotating block is fixed to the top end of the threaded rod, and the surface of the rotating block is provided with anti-slip textures.

[0010] The utility model adopts the above structure to achieve the following beneficial effects: by rotating the threaded rod, the pushing plate is driven to move downward, the pushing plate slides relative to the pushing groove, and at the same time drives the clamping plate to move out of the clamping groove, thereby releasing the fixed connection between the support block and the mounting hole, and the polishing wheel can be removed to complete the disassembly, and when installing the polishing wheel, the threaded rod can be rotated in the opposite direction to clamp the clamping plate into the clamping groove. Due to the clamping setting of the clamping plate and the clamping groove, there will be no loosening when the polishing wheel rotates, and it is more stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. The present utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1-6 As shown, the utility model is a polishing wheel that is easy to disassemble, including a base 1, a motor 2, a rotating shaft 3 and a supporting block 4. The motor 2 is fixed on the base 1, the rotating shaft 3 is arranged on the motor 2, the supporting block 4 is fixed on one end of the rotating shaft 3, a polishing wheel 14 is sleeved on the rotating shaft 3, a circular mounting hole 5 is arranged at the center of the polishing wheel 14, a clamping groove 6 is arranged on the inner side wall of the polishing wheel 14 near the mounting hole 5, a mounting groove 8 is arranged at one end of the supporting block 4, a supporting frame 9 is fixed on the bottom wall of the mounting groove 8, a clamping plate 7 is slidably provided on the supporting frame 9, and one end of the clamping plate 7 is clamped in the clamping groove 6.

[0021] like Figure 2 and Figure 3 As shown, an inclined pushing groove 13 is provided on the side wall of the clamping plate 7, and a pushing plate 12 is slidingly arranged in the pushing groove 13. A threaded rod 10 is provided on the top wall of the support frame 9 to penetrate the pushing plate 12 and rotate. The threaded rod 10 and the pushing plate 12 are threadedly connected. A rotating block 11 is fixed on the top of the threaded rod 10, and the surface of the rotating block 11 is provided with anti-slip patterns.
