Description

Technical Field

[0001] The utility model relates to the technical field of wire strippers, in particular to a wire stripper capable of loosening a front end cover of a grinding wheel machine. Background Art

[0002] The grinding wheel machine is a kind of machining tool and is currently the most commonly used cutting tool in the machinery industry. Figure 1 As shown, the cutting disc 3 and the grinding disc will further lock the front end cover 4 of the grinding machine when they rotate. In this way, when the cutting disc 3 and the grinding disc are worn out during use and need to be replaced, it is difficult to directly loosen and remove the front end cover 4 from the rotating shaft 5 of the grinding machine by hand because the front end cover 4 is locked too tightly. Therefore, a plurality of through holes 41 are designed on the front end cover 4, so that the user can use corresponding tools (such as elbow circlip pliers and other tools) to insert into the through holes 41 to loosen the front end cover 4.

[0003] However, the existing wire strippers do not have the function of removing the front end cover. In order to enable the wire strippers to have the function of removing the front end cover, a corresponding structure capable of removing the front end cover is designed on the wire strippers.

[0027] Example 1

[0028] Combination Figure 1 and Figure 2 As shown, the utility model discloses a wire stripper capable of loosening the front end cover of a grinding wheel machine, comprising:

[0029] Two pliers bodies 1 connected in rotation; the pliers body 1 comprises a pliers handle 11 and a pliers head 12 connected to the pliers handle 11;

[0030] The two pliers heads 12 have outwardly extending protrusions 2 on the side surfaces along the same direction, and the two protrusions 2 are arranged at the same height and in parallel; the protrusions 2 are used to be inserted into the through hole 41 of the front end cover 4; the shape of the part of the protrusion 2 inserted into the through hole 41 is adapted to the shape of the through hole 41.

[0031] Compared with the prior art, the utility model innovatively enables the wire stripper to have the function of loosening the front end cover 4 of the grinding machine. Specifically, two protrusions 2 are respectively provided on the two pliers bodies 1. When removing the front end cover 4, the positions of the two protrusions 2 are adjusted by rotating the two pliers bodies 1, and then the two protrusions 2 are correspondingly inserted into the two through holes 41 of the front end cover 4, and then the entire wire stripper is rotated, and the front end cover 4 is loosened by the force exerted by the protrusions 2 on the front end cover 4 through the inner wall of the through hole 41; after the front end cover 4 is loosened, the front end cover 4 is continuously rotated from the rotating shaft 5 of the grinding machine by hand until the front end cover 4 is separated from the rotating shaft 5.

[0032] In the present embodiment, the through hole 41 is a round through hole 41. Therefore, in order to make the shape of the portion of the protrusion 2 inserted into the through hole 41 compatible with the shape of the through hole 41 and to simplify the manufacturing of the protrusion 2, the overall shape of the protrusion 2 is a cylindrical structure. The part structure of the cylindrical structure is simple to process in the field of mechanical manufacturing industry. In addition, commonly used cylindrical standard parts such as screws and pins can also be used for replacement.

[0033] In this embodiment, the protrusion 2 is detachably connected to the clamp head 12, so when the protrusion 2 is damaged, the protrusion 2 can be removed from the clamp head 12 and replaced with a new one, which reduces maintenance costs.

[0034] Furthermore, the protrusion 2 is formed by a screw rod; the screw is passed through the pliers head 12 and is threadedly connected to the pliers head 12, so that the screw rod protrudes from the surface of the pliers head 12. When the screw rod is worn, the screw can be unscrewed from the pliers head 12 and replaced with a new screw. The screw is a common part, which is easy to obtain and has low maintenance cost.

[0035] In this embodiment, a hexagonal through hole 121 is formed on the pliers head 12, so that the wire stripping pliers can tighten hexagonal screws and hexagonal nuts.

[0036] In this embodiment, the pliers head 12 has at least one of a wire stripping portion 122, a wire winding portion 123, a wire splitting portion 124, a wire cutting portion, a screw breaking portion 125, a wire pressing portion 126, a wire splitting leather portion 127, and a bottle opener structure. The wire stripping portion 122, the wire winding portion 123, the wire splitting portion 124, the wire cutting portion, the screw breaking portion 125, the wire pressing portion 126, the wire splitting leather portion 127, and the bottle opener structure are all existing technical structures, and corresponding functions can be given to the wire strippers according to needs.

[0037] Example 2

[0038] The difference between Example 2 and Example 1 is that the protrusion 2 is constructed differently; in Example 2, the protrusion 2 is constructed by a pin; the pliers head 12 has a through hole 41, the pin is connected to the through hole 41 by interference fit, and the portion of the pin protruding from the surface of the pliers head 12 constitutes the protrusion 2. When the pin is worn, the pin can be pulled out of the pliers head 12 and replaced with a new pin. The pin is a common part, and the way to obtain it is as simple and convenient as a screw, and the maintenance cost is low.

[0039] Example 3

[0040] The difference between Example 3 and Example 1 and Example 2 is that in Example 3, the protrusion 2 is integrally connected to the clamp head 12, preferably by welding, or by casting or metal cutting.

[0041] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the protection scope of the utility model.

[0042] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the claims of the present invention and the scope of equivalent technologies, the present invention is also intended to include these changes and modifications.
