[0016] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0017] Embodiments of the present utility model: Figure 1 and Figure 2 As shown, a grinding wheel disassembly and assembly chuck includes a base 1 and a wrench 3. One end of the wrench 3 is fixedly connected to the middle of one side of the base 1. Two connecting plates 6 are movably mounted on the base 1. The two connecting plates 6 are located on both sides of the wrench 3. The two connecting plates 6 are fixed to the base 1 by locking assemblies, respectively. Insert rods 12 are fixed at the ends of the two connecting plates 6.

[0018] The base 1 is a rectangular structure, and the two connecting plates 6 can be adjusted along the length direction of the base 1. The distance between the two plug rods 12 can be changed by adjusting the two connecting plates 6 to adapt to grinding wheels of different specifications. The locking assembly is used to fix the connecting plates 6 on the base 1.

[0019] In a specific embodiment, a connection block 2 is fixedly provided in the middle of one side of the base 1, and one end of the wrench 3 is fixedly connected to the connection block 2. Since the base 1 is relatively thin, the firmness of the connection position of the wrench 3 and the base 1 cannot be guaranteed by directly fixing the wrench 3 to the base 1. Therefore, the connection block 2 is provided in the middle of the base 1 to improve the connection reliability of the wrench 3 and the base 1. Preferably, an arc-shaped concave surface is formed on the surface where the connection block 2 and the wrench 3 are connected, so that the outer wall of the wrench 3 can have a larger contact area with the connection block 2. A sheath is sleeved at the bottom of the outer wall of the wrench 3.

[0020] Furthermore, two mounting grooves 13 are provided on one side of the base 1 where the connecting block 2 is provided. The two mounting grooves 13 are symmetrical with respect to the connecting block 2, and the two connecting plates 6 are respectively plugged into and matched with the two mounting grooves 13. A sliding groove 5 is formed on a set of opposite side walls in the mounting groove 13, and a sliding block 7 that matches the sliding groove 5 is formed on the outer wall of the connecting plate 6.

[0021] Through the cooperation between the slide groove 5 and the slider 7, the connecting plate 6 cannot be separated from the installation groove 13, so that the connecting plate 6 can only slide along the installation groove 13. In a preferred embodiment, the slide groove 5 is a dovetail groove, and the cross-section shape of the slider 7 is a dovetail shape.

[0022] Furthermore, a first long through hole 4 is opened at the bottom of the installation groove 13, a second long through hole 8 is opened on the connecting plate 6, and the locking assembly includes a bolt 9 and a nut 10. The bolt 9 passes through the first long through hole 4 and the second long through hole 8 and is threadedly connected with the nut 10.

[0023] The first long through hole 4 is opposite to the second long through hole 8. By setting the first long through hole 4 and the second long through hole 8 and cooperating with the bolts 9 passing through them, it can be achieved that no matter which position the connecting plate 6 moves to, the connecting plate 6 can be fixed in the installation groove 13 by the cooperation of the bolts 9 and the nuts 10.

[0024] Furthermore, a top plate 11 is provided at one end of the connecting plate 6 located outside the mounting groove 13 , and the inserting rod 12 is fixed on the top plate 11 .

[0025] The working principle of the utility model is as follows: the nut 10 is loosened from the bolt 9, and the top plate 11 is pulled outward or inward, so that the top plate 11 drives the insertion rod 12, the connecting plate 6 and the slider 7 to move outward or inward in the base 1. The distance between the insertion rods 12 can be adjusted according to the aperture of the insertion hole on the grinding wheel flange. The nut 10 is tightened on the bolt 9, and the connecting plate 6 is fixed on the base 1. The insertion rod 12 is inserted into the insertion hole on the grinding wheel flange. The grinding wheel flange is disassembled and assembled by holding and rotating the wrench 3.

[0026] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
