Description

A wrench for disassembling end caps with holes

Technical field:

The utility model relates to the technical field of wrench products, in particular to a wrench for disassembling and assembling an end cover with a hole on the end face.

Background technique:

A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). When the hydraulic cylinder realizes the reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it has been widely used in various mechanical hydraulic systems.

A hydraulic cylinder generally includes a cylinder body, an end cover installed at the port of the cylinder body, a piston installed in the cylinder body, and a piston rod interlocked with the piston and extending out of the cylinder head. When assembling the end cover of the hydraulic cylinder, since the piston rod protrudes from the inner hole of the end cover with holes on the end face, the two-angle wrench with an acute angle is often used at present. This kind of two-angle wrench is difficult to apply torque and is inconvenient. The distance between the two holes on the end face of the end cover adjusts the opening size of the two feet and the diameter of the two holes, and it is easy to slip, causing scratches on the surface of the end cover, which affects the overall aesthetics of the hydraulic cylinder.

In view of this, the inventor proposes the following technical solutions.

Two positioning posts, and the relative distance between the second positioning post and the first positioning post can be adjusted by rotating the movable arm.

Furthermore, in the above technical solution, both the fixed arm and the movable arm are arc-shaped.

Further, in the above technical solution, both the first positioning column and the second positioning column are installed on the ends of the fixed arm and the movable arm by means of screw fixing, and the lower ends of the first positioning column and the second positioning column are both It protrudes outside the lower ends of the fixed arm and the movable arm.

Furthermore, in the above technical solution, the first positioning column includes a head and a positioning part fixed together, the head is installed in the fixed force arm, and the positioning part protrudes from the lower end of the fixed force arm.

Furthermore, in the above technical solution, threads are provided on the periphery of the head, threaded holes are provided in the fixing arm, and the head is screw-fixed in the threaded holes.

Furthermore, in the above technical solution, the cross section of the positioning portion is circular or polygonal.

Furthermore, in the above technical solution, the shape of the second positioning column is consistent with the shape of the first positioning column.

Furthermore, in the above technical solution, a handle sleeve is sleeved on the other end of the wrench frame opposite to the fixed arm.

Furthermore, in the above technical solution, anti-slip protrusions or anti-slip depressions are provided on the periphery of the handle cover.

After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: when the utility model is used, according to the shape and size of the hole provided on the end cover of the hydraulic cylinder, the shape and size of the hole are selected to match the shape and size of the hole. The first positioning post and the second positioning post are fixed to the ends of the fixed force arm and the movable force arm respectively. According to the distance between the holes provided on the end cover of the hydraulic cylinder, the relative distance between the second positioning post and the first positioning post can be adjusted by rotating the movable arm, so that the first positioning post and the second positioning post can be quickly inserted into the hydraulic pressure. In the hole on the end cover of the oil cylinder, the end cover of the hydraulic oil cylinder can be assembled by directly pulling the wrench frame 1 at this time. Since there is an opening formed between the fixed arm and the movable arm, the piston rod of the hydraulic cylinder can be directly straddled through the opening, that is to say, when the piston rod of the hydraulic cylinder extends longer, the utility model can also be used . In addition, the utility model also has the advantages of simple structure, convenient adjustment, convenient use, large acting torque, and is suitable for assembling end caps of various sizes, so that the utility model has extremely high market competitiveness.

Fig. 2 is a bottom view of the utility model.

Detailed ways:

Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described.

As shown in Figures 1 and 2, it is a wrench for disassembling end caps with holes on the end face, which includes a wrench frame 1, a fixed arm 11 formed at the front end of the wrench frame 1, and a hinged front end of the wrench frame 1. The movable arm 12 that can rotate relative to the fixed arm 11 has an opening formed between the end of the fixed arm 11 and the end of the movable arm 12 . Specifically, an installation position 10 is provided at the junction between the front end of the wrench frame 1 and the fixed arm 11, and the end of the movable arm 12 is installed at the installation position 10 through a stainless steel solid rivet 17. 12 can rotate relative to the fixed force arm 11.

The fixed arm 11 and the movable arm 12 are all arc-shaped, and the ends of the fixed arm 11 and the movable arm 12 are respectively equipped with a hole corresponding to the holes in the front and rear covers that need to be disassembled and replaced. The first positioning post 13 and the second positioning post 14, and the relative distance between the second positioning post 14 and the first positioning post 13 can be adjusted by rotating the movable arm 12. Specifically, the first positioning post 13 and the second positioning post 14 are installed on the ends of the fixed arm 11 and the movable arm 12 by means of screw fixing, and the lower ends of the first positioning post 13 and the second positioning post 14 are All protrude outside the lower ends of the fixed arm 11 and the movable arm 12.

The first positioning post 13 includes a fixed head and a positioning portion, and the cross section of the positioning portion is circular or polygonal. The head is installed in the fixed force arm 11 , and the positioning part protrudes outside the lower end of the fixed force arm 11 . Wherein, the periphery of the head is provided with threads, and the fixing arm 11 is provided with threaded holes, and the head is screw-fixed in the threaded holes.

The shape of the second positioning post 14 is consistent with the shape of the first positioning post 13 , and will not be repeated here again.

The other end of the wrench frame 1 opposite to the fixed arm 11 is sleeved with a handle cover 15 , wherein an anti-slip protrusion or an anti-slip depression 151 is provided on the periphery of the handle cover 15 .

When the utility model is in use, according to the shape and size of the hole provided on the end cover of the hydraulic oil cylinder, select the first positioning column 13 and the second positioning column 14 that match the shape and size of the hole, and place the first positioning column 13 and the second positioning post 14 are fixed to the ends of the fixed arm 11 and the movable arm 12 respectively. According to the spacing of the holes provided on the end cover in the hydraulic cylinder, the relative distance between the second positioning post 14 and the first positioning post 13 is adjusted by rotating the movable arm 12, so that the first positioning post 13 and the second positioning post 14 can be quickly embedded in the hole on the end cover of the hydraulic oil cylinder, and at this moment, the end cover of the hydraulic oil cylinder can be assembled by directly pulling the wrench holder 1. Since an opening is formed between the fixed arm 11 and the movable arm 12, the piston rod of the hydraulic cylinder can be directly crossed through the opening, that is to say, when the piston rod of the hydraulic cylinder stretches out longer, the utility model also be usable.
