Abstract
The invention discloses a hole retainer processing method. The hole retainer processing method includes steps of blanking a metal plate into a circle, forming a hole retainer base body, and increasing size allowance of an outer circle in the blanking process design; machining to remove the size allowance of the outer circle so as to enable the surface of the outer circle to be smooth and taper-free, and obtaining a hole retainer processing state base body; cutting the hole retainer processing state base body so as to form an opening. The invention further provides a hole retainer manufactured by the hole retainer processing method. The hole retainer comprises an annular base body. A center hole is formed in the middle of the base body. The base body is provided with a preset thickness and an opening. The base body is enclosed by two annular planes, an inner side and an outer side, and an opening is formed between the two annular planes. The size allowance of the outer circle of the hole retainer is increased, the hole retainer is manufactured by machining the outer circle of the hole retainer through machining, the outer side of the outer circle is smooth and taper-free, and during assembling and using, the hole retainer is large in contact area when being stressed, is uniform in stress and cannot jump out.
Description
Technical field
The present invention relates to the back-up ring technical field, relate in particular to back-up ring and processing method thereof for a kind of hole.
Background technology
In prior art, the hole that structure is the opening annulus is machine components commonly used with back-up ring, and it has the design standard of standard, and its Main Function is the cast parts that are fastened on axle, can prevent from being contained in other part plaies on axle, belongs to a kind of securing member.In actual production, the phenomenon that eject with back-up ring in hole can occur with back-up ring in the hole produced according to GB in the assembling use procedure, this is mainly because the GB mesopore is larger by the external diameter tolerance of back-up ring, there is the big and small arc surface of staying in hole with back-up ring, and there is an obvious tapering in cylindrical, while causing hole stressed with back-up ring, contact area is too small, and hole is jumped out after stressed with back-up ring.
Summary of the invention
In order to solve the technical problem existed in background technology, the present invention proposes back-up ring and processing method thereof for a kind of hole, realized optimal design and the processing technology improvement of hole with back-up ring, it is rational in infrastructure, manufacturing process is simple, can effectively prevent stressed jumping out, thus make fixed, accurate positioning.
The processing method of back-up ring for a kind of hole comprises the following steps:
S1, sheet metal is carried out to stamping-out process and to obtain circle, form hole back-up ring matrix, and in Stamping process design, increase excircle dimension surplus;
The size surplus of cylindrical is removed in S2, machined, makes the level and smooth zero draft of outer round surface, obtains back-up ring processing state matrix for hole;
S3, otch is carried out to back-up ring processing state matrix in hole, make it there is opening.
A kind of hole back-up ring, comprise annular matrix, at described matrix middle part, form centre bore, described matrix has predetermined thickness and has an opening, described matrix is surrounded by two planar annulars, medial surface and lateral surfaces, forms described opening between described two planar annulars.
Preferably, the level and smooth zero draft of the lateral surface of described matrix.
Preferably, described opening two ends are respectively arranged with the first syndeton and the second syndeton, and by the aperture of described the first syndeton, the fixing described opening of described the second syndeton.
Preferably, described the first syndeton, described the second syndeton are the first through hole, the second through hole that runs through described matrix.
Preferably, described medial surface is level and smooth.
Preferably, described hole with back-up ring at uniform thickness in the radial direction.
In the present invention, adopt and increase the size surplus of hole with the back-up ring cylindrical, and by mach mode, hole is processed with the back-up ring cylindrical, the hole back-up ring made by this technique, the level and smooth zero draft of its lateral surface, therefore, use procedure is being assembled with back-up ring in hole, when stressed, contact area is large, stressed even, can not jump out.
The accompanying drawing explanation
Fig. 1 is the schematic flow sheet of a kind of hole that proposes of the present invention by the processing method of back-up ring;
Fig. 2 is the structural representation of a kind of hole that proposes of the present invention with back-up ring.
The specific embodiment
As shown in Figure 1, Fig. 1 is the schematic flow sheet of a kind of hole that proposes of the present invention by the processing method of back-up ring; Fig. 2 is the structural representation of a kind of hole that proposes of the present invention with back-up ring.
With reference to Fig. 1, the processing method of back-up ring for a kind of hole that the present invention proposes comprises the following steps:
S1, sheet metal is carried out to stamping-out process and to obtain circle, form hole back-up ring matrix, and in Stamping process design, increase excircle dimension surplus;
The size surplus of cylindrical is removed in S2, machined, makes the level and smooth zero draft of outer round surface, obtains back-up ring processing state matrix for hole;
S3, otch is carried out to back-up ring processing state matrix in hole, make it there is opening.
With reference to Fig. 2, a kind of hole back-up ring that adopts above-mentioned hole to make by the processing method of back-up ring that the present invention proposes, comprise annular matrix 1, form centre bore 2 at described matrix 1 middle part, the size of centre bore 2 and size can be passed through bearing, described matrix 1 has predetermined thickness and has an opening 16, and described matrix 1 is surrounded by two planar annulars 11, medial surface 12 and lateral surface 13, forms described opening 16 between described two planar annulars 11.
In the present embodiment, the level and smooth zero draft of lateral surface 13 of matrix 1, the level and smooth zero draft of medial surface 12, lateral surface 13 is vertical with planar annular 11 with medial surface 12, thereby ensured that hole is enough large by back-up ring contact area when stressed, thereby ensured that hole is stressed evenly with back-up ring, can not beat in use procedure.
In the specific design process, opening 16 two ends of matrix 1 are respectively arranged with the first through hole 14, the second through hole 15 that runs through matrix 1, and pass through the aperture of the first through hole 14, the second through hole 15 permanent openings 16, thereby better control the aperture of the opening 16 of matrix 1.
In the present embodiment, hole at uniform thickness in the radial direction, is further improved the stressed uniformity of hole with back-up ring with back-up ring, improves the stability in the back-up ring use procedure for hole.
In the present invention, adopt and increase the size surplus of hole with the back-up ring cylindrical, and by mach mode, hole is processed with the back-up ring cylindrical, the hole back-up ring made by this technique, the level and smooth zero draft of its lateral surface, therefore, use procedure is being assembled with back-up ring in hole, when stressed, contact area is large, stressed even, can not jump out.
