Abstract

The utility model provides a bearing head with a novel structure for the press fitting of the automobile bearing components in the field of automobile components assembly engineering. The bearing headwith the novel structure is additionally provided with an air jacket (1), a gas hole (2), an air groove (3) and another gas hole (5), the air jacket (1) is arranged in the bearing head (4), the air groove (3) is arranged between the air jacket (1) and the bearing head (4), the gas hole (2) is connected with the air groove (3), the gas hole (2) extends out of the left end surface (6) of the bearing head, the bearing head (4) is provided with the gas hole (5) communicated with the air groove (3). In the utility model, the structure can effectively prevent the bearing from being returned with the head, the reworking amount can be decreased, and the productivity effect can be effectively improved.

Description

A kind of bearing pressure head of new structure

Technical field

The utility model relates to a kind of auto parts and components assembly tooling field, more particularly, relates to a kind of bearing pressure head that is used for the new structure that the automobile bearing type component press-fits.

Background technology

Existing pressure head is in the middle of the process of assembling, and lathe is sent bearing into bearing by manipulator and corrected in the chamber, and pressure head holds bearing by magnetic force, and pressure head is realized press-fiting under the promotion of electronic cylinder.Because between bearing and the housing is interference fits, adds mismachining tolerance, thereby causes having the gap between bearing and the housing, when press-fiting release, owing to also have certain magnetic force, the bearing difficult drop-off on the pressure head, bearing is followed pressure head and is returned together, thereby causes frequent neglected loading.

The utility model content

Technical problem to be solved in the utility model is: provide a kind of bearing that can effectively prevent to follow the bearing pressure head and return together, and reduced the amount of doing over again, the bearing pressure head of the new structure of effectively enhancing productivity.

For solving above technical problem, the technical solution adopted in the utility model is:

The utility model is a kind of bearing pressure head of new structure, set up away air-casing on the bearing pressure head of described new structure, gas hole, walk air drain, pore, the described flat bearing pressure head inside that is set on, walk between air-casing and the bearing pressure head to walking air drain, gas hole with walk air drain and be connected, gas hole extends bearing pressure head left side, is provided with on the bearing pressure head and walks the pore that air drain is communicated with.

Described flat be enclosed within bearing pressure head left side by the projection with bearing pressure head internal edges along applying.

The described air drain of walking is set at the bearing pressure head and walks between the air-casing along the circumference structure in one week.

Described pore is arranged on the position of bearing pressure head body rear end.

Adopt the technical solution of the utility model, can obtain following beneficial effect:

Structure of the present utility model can prevent effectively that bearing from following pressure head and returning together, and has reduced the amount of doing over again, effectively the production efficiency that improves.

Description of drawings

Below expressed content of each width of cloth accompanying drawing in this specification and the mark among the figure are briefly explained:

Fig. 1 is the structure cross-sectional schematic of the bearing pressure head of new structure described in the utility model;

Fig. 2 is the structure cross-sectional schematic of existing bearing pressure head;

Be labeled as among the figure: 1, walk air-casing; 2, gas hole; 3, walk air drain; 4, bearing pressure head; 5, pore; 6, bearing pressure head left side; 7, bearing pressure head body rear end; 8, projection.

The specific embodiment

Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are described in further detail embodiment:

As shown in Figure 1, the utility model is a kind of bearing pressure head of new structure, set up away air-casing 1 on the bearing pressure head of described new structure, gas hole 2 is walked air drain 3, pore 5, the described air-casing 1 of walking is arranged on bearing pressure head 4 inside, walk between air-casing 1 and the bearing pressure head 4 to walking air drain 3, gas hole 2 with walk air drain 3 and be connected, gas hole 2 extends bearing pressure head left side 6, is provided with on the bearing pressure head 4 and walks the pore 5 that air drain 3 is communicated with.

Described walk air-casing 1 in bearing pressure head left side 6 by projection 8 and bearing pressure head 4 internal edges along applying.

The described air drain 3 of walking is set at bearing pressure head 4 and walks between the air-casing 1 along the circumference structure in one week.

Described pore 5 is arranged on the position of bearing pressure head body rear end 7.

Pressure head after the improvement is by increasing by one and walk air-casing (walking air-casing 1 and bearing pressure head 4 close-fittings) in that the bearing pressure head being inner, and gas is come in from pore 5, through walk air drain 3 (walk air drain be positioned at air-casing around) to gas hole 2, reach the purpose of the bearing that blows off.

In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the concrete realization of the utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or design of the present utility model and technical scheme are directly applied to other occasions without improving, all in protection domain of the present utility model.
