[0002] Grinding wheel dressing is an operation process of using a dressing tool to dress the grinding wheel into a shape or remove the dull surface layer to restore the grinding performance of the working surface and the correct geometric shape. Timely and correct dressing of the grinding wheel is an essential important link to improve the grinding efficiency and ensure the grinding quality. The existing grinding wheel dressing devices are large in volume and weight, not convenient to move, and not flexible enough to use. Summary of the Invention

[0003] The purpose of the utility model is to provide a hand-held grinding wheel dressing device with small volume, light weight and convenient operation.

[0004] The technical scheme adopted by the utility model is as follows: A hand-held grinding wheel dressing device includes a handle. A main shaft is fixedly installed at the upper end of the handle. A rotating body is sleeved on the main shaft. The rotating body is rotationally matched with the main shaft through a bearing. A cover plate is fixedly installed at one end of the rotating body close to the handle to limit and cover the bearing. A gasket is sleeved on the main shaft at the end far from the handle and abuts against the bearing, and the bearing is fixed by pressing the gasket with a first bolt. A grinding wheel dresser is sleeved on the rotating body and fixed to the rotating body by a baffle.

[0005] Further, a first step portion and a second step portion are arranged on the main shaft. The first step portion abuts against the handle and cooperates with a second bolt to fix the main shaft to the handle. The bearing abuts against the second step portion, and the bearing is limited by the second step portion.

[0006] Further, the cover plate is fixed to the rotating body by screws.

[0007] Further, the rotating body is rotationally matched with the main shaft through two bearings.

[0008] Further, a bent portion biased towards one side of the grinding wheel dresser is arranged at one end of the handle far from the main shaft.

[0009] The hand-held grinding wheel dressing device of the utility model is applicable to the dressing of grinding wheels by tool grinders and cylindrical grinders. It has small volume, light weight and convenient operation, improves the processing efficiency, and is especially suitable for the dressing of flat wheels. Through the cooperation of various components, the grinding wheel dresser can rotate smoothly without swinging, and the dressed grinding wheel is flat and the grinding wheel dressing efficiency is greatly improved. Most parts of this device are standard parts, which can achieve quick disassembly and replacement. The grinding wheel dresser can use waste grinding wheels, which can be reused and reduce the production cost. Brief Description of the Drawings

[0010] Figure 1 It is a schematic diagram of the overall structure of the present utility model.

[0011] Figure 2 It is a schematic diagram of the structure of the main shaft of the present utility model. Specific embodiments

[0012] To facilitate the understanding of the present utility model, the following will describe the present utility model more comprehensively and meticulously in conjunction with the specification drawings and preferred embodiments, but the protection scope of the present utility model is not limited to the following specific embodiments.

[0013] As Figure 1 、 Figure 2 shown, this embodiment provides a hand-held grinding wheel dressing device, including a handle 1. At the upper end of the handle 1, a main shaft 2 is fixedly installed. A rotating body 8 is sleeved on the main shaft 2. The rotating body 8 and the main shaft 2 are rotationally matched through a bearing 11. At one end of the rotating body 8 close to the handle 1, a cover plate 4 is fixedly installed to limit and seal the bearing 11, and at the same time limit the horizontal movement of the bearing 11. The cover plate 4 is fixed to the rotating body 8 by screws 5, which is convenient for disassembly and assembly. At one end of the main shaft 2 away from the handle 1, a gasket 10 is sleeved tightly against the bearing 11, and the bearing 11 is fixed by pressing the gasket 10 with a first bolt 9. A grinding wheel dressing wheel 6 is sleeved on the rotating body 8, and the grinding wheel dressing wheel 6 is fixed to the rotating body 8 by a baffle 7.

[0014] In this embodiment, a first step portion and a second step portion are provided on the main shaft 2. The first step portion abuts against the handle 1 and cooperates with a second bolt 3 to fix the main shaft 2 to the handle 1. The bearing 11 abuts against the second step portion, and the bearing 11 is limited by the second step portion.

[0015] In this embodiment, the rotating body 8 is rotationally matched with the main shaft 2 through two bearings 11. Using double bearings for transmission can reduce friction, make the grinding wheel dressing wheel 6 rotate more flexibly, avoid the phenomenon of locking, and extend the service life.

[0016] In this embodiment, at one end of the handle 1 away from the main shaft 2, there is a bent portion biased towards one side of the grinding wheel dressing wheel 6. In this embodiment, the handle 1 is designed as a two-section type instead of a conventional straight handle, and the advantage of this is that it is convenient for clamping.

[0017] With the aid of the teachings presented in the foregoing specification and the associated drawings, those skilled in the art to which the present utility model pertains will envision numerous modifications and other embodiments of the present utility model. Accordingly, it is to be understood that the present utility model is not limited to the specific embodiments disclosed, and that modifications and other embodiments are regarded as being included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
