Abstract
The invention relates to a sliding bearing fixing device. The sliding bearing fixing device comprises a roller tool and a rapping rod mechanism. The roller tool is a cuboid with an upper arc surface and a lower arc surface, a through hole is vertically formed in the center from the upper spherical surface to the lower spherical surface, and a conical opening is formed in the lower end of the through hole. The rapping rod mechanism comprises a base plate, a rapping rod and a steel ball. The rapping rod is cylindrical, one end of the rapping rod is vertically connected with the base plate, the other end of the rapping rod is connected with the steel ball, and the rapping rod is inserted into the through hole to connect the rapping rod mechanism with the roller tool. By means of the sliding bearing fixing device, uncontrollable deformation and uncontrollable material slippage which are caused by originally rapping thin-walled parts directly become controllable and adjustable; and fixing is carried out through a slot, other relevant fixing devices are omitted, the structure is simple, and installing and operating are convenient.
Description
Technical field
The invention belongs to bearing fixing device technical field, particularly relate to a kind of sliding bearing fixture.
Background technology
The mode of fixing sliding bearing in current domestic POLCAIN motor piston assemblies is a lot, but most fixture design and processes is complicated, and unfailing performance is lower, often cause sliding bearing to be out of shape and material slippage owing to knocking, this brings great inconvenience to production and work.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of sliding bearing fixture, to solve the problem that on market, the design of sliding bearing fixture is complicated, unfailing performance is low.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of sliding bearing fixture, comprising roller frock and strike linkage, described roller frock is the cuboid of upper and lower arc surface, and upper sphere is provided with through hole to lower peripheral surface central vertical, described through hole lower end is bell; The described linkage that strikes comprises backing plate, strikes bar and steel ball, and the described bar that strikes is cylinder, and described one end of striking bar is connected with backing plate is vertical, and the other end is connected with steel ball, and the described bar that strikes is inserted in through hole and makes to strike linkage and be connected with roller frock.
The described diameter striking bar is less than the diameter of through hole.
The diameter of described steel ball is corresponding with the diameter of through hole.
The large mouth of described bell inside hole, osculum is in outside.
Beneficial effect
Advantage of the present invention:
1, structure of the present invention is simple, is only made up of two parts, installs easy to operate, and centering is easy, and reliability is high;
2, the present invention can be fixed by draw-in groove, saves other associated anchor;
3, the slippage that the present invention makes originally directly to knock distortion that thin-walled parts produces and material becomes controlled and adjustment by uncontrollable, under the laminating extruding of roller frock, plunger, distortion and material slippage occur over just and need position and plunger centre bore, ensure that sliding bearing installation dimension, sliding bearing is coordinated with roller unaffected;
4, the present invention can also be applied to other field, and by being adjacent to material, local deformation screens realizes fixture.

Detailed description of the invention
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
Embodiment 1
As shown in Fig. 1 ~ 5, a kind of sliding bearing fixture, comprising roller frock 2 with strike linkage 1, described roller frock 2 is the cuboid of upper and lower arc surface, and upper sphere is provided with through hole 3 to lower peripheral surface central vertical, and described through hole 3 lower end is bell 7; The described linkage 1 that strikes comprises backing plate 4, strikes bar 5 and steel ball 6, described strikes bar 5 for cylinder, described one end of striking bar 5 is connected with backing plate 4 is vertical, and the other end is connected with steel ball 6, and the described bar 5 that strikes is inserted in through hole 3 and makes to strike linkage 1 and be connected with roller frock 2.Beaten by bucketing bar 5 or to impact or the mode such as press pressing makes sliding bearing 9 produces pit and is stuck in corresponding plunger centre bore 11, being fixed.
The described diameter striking bar 5 is less than the diameter of through hole 3, conveniently strikes bar 5 and is inserted in the through hole 3 of ball frock 2.
The diameter of described steel ball 6 is corresponding with the diameter of through hole 3, and steel ball just can be inserted in through hole 3.
The large mouth of described bell 7 inside hole, osculum in outside, just some can be extruded by through hole 3 pairs of sliding bearings 9 to make steel ball 6.
Plunger 8 is installed on tooling platform 10 fixing, sliding bearing 9 is installed on plunger 8, then the bell 7 of roller frock 1 of the present invention is encased in plunger 8 down, and the lower arc surface of roller frock 1 is contacted with sliding bearing 9, roller frock both ends of the surface are concordant with plunger mating surface, make to strike the position that the steel ball 6 on linkage 2 exposes roller frock 1 by bell 7 like this to align with plunger centre bore 11, by beaing backing plate or impacting or the mode such as press pressing makes sliding bearing 9 produces pit, and be stuck in corresponding plunger centre bore 11, be fixed.
