Preferably, the depth of the relief opening is 5mm, and the error range is between 0 and 0.05 mm.

Preferably, the depth of the deep groove is 2mm, and the error range is between 0 and 0.05 mm.

Preferably, an inner groove is formed in the middle of the press-fitting main body.

The utility model provides a bottom location frock, includes lip oil blanket pressure equipment and frock main part, and lip oil blanket pressure equipment is located frock main part top side, frock main part and the mutual pressfitting of pressure equipment main part, and the bottom side welding of frock main part has the bottom plate, the avris of bottom plate sets up a plurality of bolts that are used for connecting bottom plate and frock face.

Preferably, the middle part of the tool main body is integrally connected with an inner clamping block, and an area formed between the inner cavity of the tool main body and the outer surface of the inner clamping block is a bottom groove.

Compared with the prior art, the invention provides a double-lip oil seal press-fitting and bottom positioning tool, which has the following beneficial effects:

this application satisfies the oil blanket pressure equipment requirement before the gear room of lips mouth structure, does not damage the oil blanket, has solved the current pressure equipment frock in post and has pressed the protruding lip of oil blanket before the gear room of lips mouth structure, influences the problem of oil blanket leakproofness.

Detailed Description

The following further describes a specific embodiment of the double-lip oil seal press-fitting and bottom positioning tool in combination with fig. 1. The double-lip oil seal press-fitting and bottom positioning tool is not limited to the description of the following embodiments.

The embodiment provides a specific structure for press mounting of a double-lip oil seal, and as shown in fig. 1-3, the press mounting of the double-lip oil seal comprises a press mounting main body 1, wherein a yielding opening 4 for an oil seal lip is formed in the side of the press mounting main body 1, and a deep groove 5 for determining the press-in depth is formed in the outer area of the yielding opening 4.

When the tool is assembled, the piston cylinder is utilized to drive the press-fitting main body 1 to be vertically pressed into the tool main body 2.

As shown in fig. 2, the depth of the abdicating hole 4 is 5mm, and the error range is between 0 and 0.05 mm;

as shown in fig. 3, the depth of the deep groove 5 is 2mm, and the error range is 0-0.05 mm;

specifically, the aforesaid lets a mouthful 4 and deep trouth 6 degree of depth data all can carry out normal use in error range, let simultaneously that a mouthful 4 adopts be the notch design of indent formula, and deep trouth 5 then adopts the cell body design of semi-open formula, conveniently carries out the degree of depth and confirms.

As shown in fig. 1, an inner groove 3 is formed in the middle of the press-fitting body 1.

The inner groove 3 is composed of two open grooves which are communicated with each other to form a groove body structure with a T-shaped section, so that the subsequent matching use with the tool main body 2 is convenient.

As shown in fig. 1, a bottom positioning tool comprises a double-lip oil seal press-fitting body and a tool main body 2, wherein the double-lip oil seal press-fitting body is located on the top side of the tool main body 2, the tool main body 2 and the press-fitting body 1 are mutually pressed, a bottom plate 6 is welded on the bottom side of the tool main body 2, and a plurality of bolts used for connecting the bottom plate 6 and a tool surface are arranged on the side of the bottom plate 6.

The tool main body 2 and the press-fitting main body 1 are in corresponding positions, when the tool main body is used, an oil seal is pressed and fitted into a gear chamber, the tool main body 2 at the bottom is pushed up by a machine, the oil seal is positioned, and then the press-fitting main body 1 is used for press-fitting from the top;

the tool main body 2 and the press-fitting main body 1 belong to a set of components, are mutually matched for use, and cannot realize expected effects when being used alone.
