[0019] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] It is worth noting that the directional words such as "upper" and "lower" involved in this article are all relative to the viewing angle of the drawings and are only for the convenience of description and cannot be understood as limitations on the technical solution.

[0021] The utility model proposes a tool for replacing a grinding wheel saw blade based on two circular holes on the end surface of a hydraulic nut. Figure 1-2 As shown, it includes a connecting base plate and an adjusting member, the connecting base plate includes an integrally formed connecting plate 1 and a force-bearing plate 2, the force-bearing plate 2 is arranged on one side of the connecting plate 1, a strip-shaped adjustment groove 4 is arranged in the connecting plate 1, and a fixing column 3 is also arranged in the connecting plate 1, the fixing column 3 and the adjustment groove 4 are in the same straight line, and the adjusting member and the fixing column 3 are adapted to the round hole of the hydraulic nut.

[0022] The working process of the utility model is: according to the distance between the two circular holes on the end face of the hydraulic nut, the adjustment piece is moved to make the distance between the adjustment piece and the fixing column 3 the same as the distance between the two circular holes, and then one end of the adjustment piece and one end of the fixing column 3 are respectively embedded in the two circular holes to achieve the connection between the tool and the hydraulic nut; the force plate 2 is struck to drive the hydraulic nut to rotate through the connecting plate 1. It is easy to understand that the adjustment piece provided in the utility model enables the tool to be applicable to a variety of hydraulic nuts.

[0023] Furthermore, the ends of the adjusting member and the fixing column 3 on the same side are flush.

[0024] Furthermore, a soft rubber layer is provided on the outer side of the fixing column 3, the outer diameter of the fixing column 3 is smaller than the inner diameter of the circular hole, and the outer diameter of the soft rubber layer is larger than the inner diameter of the circular hole, that is, the fixing column 3 with the soft rubber layer is interference fit with the circular hole, ensuring that the tool will not be easily dislodged during the knocking process. It is easy to understand that when installing the tool, the connecting plate 1 is knocked from the outer side of the connecting plate 1 to make the fixing column 3 with the soft rubber layer embedded in the circular hole. Similarly, when the tool needs to be removed from the hydraulic nut, the force plate 2 is knocked in the opposite direction to make the connecting plate 1 dislodged.

[0025] In the present utility model, the adjustment member includes an adjustment column 5 and a locking nut 6. A limiting portion 7 is provided at one end of the adjustment column 5, that is, the adjustment column 5 is similar to a bolt structure. The other end of the adjustment column 5 passes through the adjustment slot 4 and is on the same side as the fixed column 3. An external thread is provided on the side of the adjustment column 5. The locking nut 6 is screwed in from the end of the adjustment column 5 away from the limiting portion 7 to lock the adjustment column 5 with the connecting plate 1. When the adjustment column 5 needs to be moved, the locking nut 6 is loosened. After the position of the adjustment column 5 is determined, the adjustment column 5 is locked with the connecting plate 1 under the action of the limiting portion 7 and the locking nut 6.

[0026] Furthermore, the adjustment member also includes a soft rubber tube, which is arranged at one end of the adjustment column 5 away from the limiting portion 7. An internal threaded surface is arranged inside the soft rubber tube, and the soft rubber tube is threadedly connected to the adjustment column 5. The outer diameter of the adjustment column 5 is smaller than the inner diameter of the circular hole, and the outer diameter of the soft rubber tube is larger than the inner diameter of the circular hole. The soft rubber tube makes the adjustment member as a whole have an interference fit with the circular hole. It is easy to understand that when installing the tool, the adjustment member and the fixing column 3 are both interference fit with the two circular holes to ensure that the tool will not fall off when the tool is struck to rotate the hydraulic nut. The soft rubber tube does not hinder the loosening or tightening of the locking nut 6, and the threaded connection between the soft rubber tube and the adjustment member can also prevent the adjustment member from falling out of the soft rubber tube during the striking process.

[0027] Furthermore, in order to improve the stability of the connection between the tool and the hydraulic nut during the knocking process, the tool also includes a fixing plate 8, which is bonded and fixed to the end face of the hydraulic nut. A connecting piece 9 is provided on the side of the fixing plate 8 away from the hydraulic nut. The connecting piece 9 is provided with an external thread. The connecting plate 1 is provided with a connecting through hole adapted to the connecting piece 9. The fixing nut 10 is threadedly connected to the connecting piece 9 to lock the fixing plate 8 and the connecting plate 1.

[0028] Before installing the tool in front of the hydraulic nut end, first lock the fixing plate 8 and the connecting plate 1, and then determine the distance between the adjusting part and the fixing column 3; apply adhesive on the surface of the fixing plate 8 facing the hydraulic nut, and then install the tool, the fixing plate 8 and the hydraulic nut are bonded, and the adjusting part and the fixing column 3 are respectively embedded in the two circular holes.

[0029] The connection between the fixing plate 8 and the hydraulic nut is achieved by bonding, without the need for additional drilling, and the fixing plate 8 and the connecting base plate are detachably connected. After the hydraulic nut is removed, the connecting base plate can be removed, and the operation is simple and quick.

[0030] There are two fixing plates 8, which are respectively located above and below the adjusting member and the fixing column 3, and are parallel to the adjusting slot 4. When knocking and disassembling the hydraulic nut, the fixing plates 8 located above and below the fixing column 3 and the adjusting member effectively prevent the tool from falling out.

[0031] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
