Description

Technical Field

[0001] This utility model relates to the field of grinding tool technology, specifically a flap wheel assembly disc. Background Technology

[0002] Currently, most flap wheel assembly discs on the market use traditional bolt fixing or simple clamping structures, which have the following problems:

[0003] 1. Insufficient clamping stability: The grinding wheel is prone to loosening when rotating at high speed, which can lead to a decrease in grinding accuracy or even safety hazards;

[0004] 2. Low installation efficiency: It requires the use of additional tools (such as wrenches) to tighten multiple times, making the operation cumbersome.

[0005] Therefore, we propose a flap wheel assembly plate to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a flap wheel assembly disc to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a flap wheel assembly disc, comprising: a first clamping accessory and a second clamping accessory, the first clamping accessory and the second clamping accessory being threadedly connected, the first clamping accessory including a first toothed disc, the second clamping accessory including a second toothed disc, the first toothed disc and the second toothed disc being designed opposite to each other, a grinding wheel being clamped between the first toothed disc and the second toothed disc, the grinding wheel being sleeved at the connection between the first clamping accessory and the second clamping accessory, the threads of the first clamping accessory and the second clamping accessory being tightened so that the first toothed disc and the second toothed disc are tightly fitted to the side of the grinding wheel.

[0008] Preferably, the first clamping accessory is radially fixedly connected to the output end of the hand drive structure, and the second clamping accessory is rotatably connected to the handle.

[0009] Preferably, the first clamping accessory further includes a first transmission sleeve and a threaded post, the first transmission sleeve and the threaded post being integrally and coaxially disposed on both sides of the first gear plate.

[0010] Preferably, a limiting hole is provided in the first transmission sleeve, and the limiting hole is radially fixedly inserted into the drill bit of the drive structure.

[0011] Preferably, the second clamping accessory further includes a second transmission sleeve and an internal threaded sleeve, the second transmission sleeve and the internal threaded sleeve being integrally and coaxially disposed on both sides of the second gear plate, and the second transmission sleeve being rotatably connected to the handle.

[0012] Preferably, the internal threaded sleeve and the threaded post are threadedly connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The grinding wheel is directly driven to rotate by a pistol drill or angle grinder. With the handle, it can achieve precise grinding and polishing, improving work efficiency. The relative meshing design of the first and second toothed discs, combined with the thread tightening force, makes the side of the grinding wheel evenly stressed, preventing loosening during high-speed rotation.

[0015] 2. The direct screw-on structure of the internal threaded sleeve and the threaded post allows for the fixing of the grinding wheel without the need for auxiliary tools, greatly improving operational efficiency;

[0016] 3. The limiting hole of the first transmission sleeve is radially inserted into the head of a hand drill or angle grinder, which is compatible with various drill bit specifications. At the same time, the rotating connection design between the handle and the second transmission sleeve enhances human-machine interaction.

[0017] 4. The toothed structure of the face toothed disc can effectively disperse the radial stress during rotation, extending the service life of the grinding wheel and clamping accessories. Attached Figure Description
