Description

Multi-directional nut wrench

The utility model relates to a multi-directional nut wrench, in particular to a nut wrench technology which can achieve the functions of disassembling and locking and improving the applicability.

Pressing, the shaft locking nut is mainly used for screwing on the shaft to further lock the load member (such as a pulley or a bearing seat) which is tightly set on the shaft. Specifically, the most common use of the shaft lock nut is to mount the bearing spindle or the bearing housing on the ball screw. In general, the shaft locking nut has a threaded through hole for screwing with the threaded portion of the spindle to urge the load member on the shaft.

A hand tool for disassembling a shaft lock nut, as shown in the first and second figures of the invention of the invention No. I390122, includes a handle 42 having a drive portion 41 connected to one end thereof. The inner surface of the driving portion 41 forms a matching surface 412 which cooperates with the outer circumferential surface of the shaft locking nut 5. The front end of the driving portion 41 is provided with a fitting member 411 for locking on the shaft locking nut 5 . The outer peripheral groove 51, when the grip 42 is biased in one direction, drives the shaft lock nut 5 to be screwed or loosened relative to the main shaft. Since the abutment surface 412 of the conventional structure driving portion 41 must cooperate with the outer peripheral arc surface of the shaft lock nut 5 as a driving surface for driving the shaft lock nut to rotate, the conventional structure can only be disassembled. A shaft-locking nut with a round diameter fit. Assuming that it is necessary to disassemble the shaft locking nut of different size outer diameters, the shaft locking nut hand tool of the matching surface 412 of different diameters must be assembled to achieve the purpose of disassembly and locking. This will not only cause The inconvenience and troubles are used, and the shaft-locking nut hand tool of the different-diameter round-face fitting surface 412 must be prepared, thereby causing an increase in the use cost.

Further, the patent shown in the "Hand Tool for Locking Nuts" of the above-mentioned Invention No. I390122 is mainly for the improvement of the above-mentioned conventional structure due to the inability to extend into the bearing seat as shown in the third and fourth figures of the invention. . It includes a body and a handle. The main body is provided with a plurality of accommodating holes on one end surface, and each of the accommodating holes has an angle. The end cover is disposed on the end surface of the body having the receiving hole, and the end cover is provided with a sliding hole opposite to the receiving hole. A plurality of elastic members are disposed in the receiving holes, and one end of the elastic member is in contact with the receiving holes. The plurality of latches are formed by a limiting section and an insertion section. The limiting section is disposed in the receiving hole, and one end of the limiting section is in contact with the other end of the elastic member, and the limiting section is given an elastic force by the elastic member to make the limiting section The other end is in contact with the inner end surface of the end cover, the insertion section is disposed in the sliding hole and protrudes from the outer end surface of the end cover, and the insertion section is slidable in the sliding hole, and the insertion section can be inserted into the locking nut Set the slot.

The conventional structure can be extended into the bearing housing as shown in the third and fourth embodiments of the invention to achieve the function of disassembling or locking the shaft locking nut; however, the patent does not have the function setting for adjusting the position of the bolt. Therefore, the position of the bolt is a fixed structure. When it is necessary to disassemble the shaft locking nut of different diameters, it is necessary to use another type of locking nut hand tool with different pin positions to disassemble the size. The locking nut of the diameter. In this case, not only the inconvenience and trouble of use, but also the locking nut hand tools of various pin positions must be prepared, so that the locking nuts of various sizes and outer diameters can be disassembled, thereby causing an increase in the use cost.

The reason is that the above-mentioned conventional structure is indeed not perfect, and there is still a need for further improvement. In view of this, the applicant is actively engaged in research and development, and after continuous research, design and implementation, there is a new type of research and development. Results.

The first object of the present invention is to provide a multi-directional nut wrench, which mainly makes the nut wrench not only disassemble the locking nut exposed on one side of the bearing housing, but also can change the position of the nut wrench fitting. The locking nut hidden in the bearing housing is removed to increase the convenience and applicability of disassembling and locking the locking nut. The technical means for achieving the first purpose includes a card mechanism and a handle. The locking mechanism is provided with a plurality of protruding fittings on one side of the equidistant ring, wherein each of the fittings is configured to be engaged with a plurality of positioning holes of the nut, and the axis of the positioning hole is parallel to the axis of the screw hole of the nut. By the urging force of the handle, the nut is driven to rotate in a direction relative to the main shaft, so that the function of disassembling or locking the nut can be achieved.
