The assembling process is as follows: a piston is placed on the piston dust cover so as to lead the bottom surface of the piston to cover the inner circle of an upper opening of the piston dust cover, an oil inlet hole at the lower end of the brake calipers is used for leading compressed air to enter so as to open the piston dust cover which moves upwards along the outer cylindrical surface of the piston to cover the outer circle of the piston, then the bottom surface of the inner hole of the piston is pushed by a push rod; and when the piston moves to the bottom of the cylinder hole of the brake calipers, the inner edge of the piston dust cover is embedded in the inner circle of the piston dust cover, thus completing the assembly. Therefore, the utility model has ingenious conception, simple and fast assembly and high efficiency, and can not scratch the surface of the piston.
Description
Technical field
The utility model relates to the rubber parts assembling device of part, can be widely used in the assembling of the dustproof class rubber part of mechanical industry, is particularly useful for the mounting technology field of dust protection rubber part in the automotive brake.
Background technology
Car hydraulic brake adopts disc type and drum brake usually at present, wherein all utilize reciprocating motion of the pistons to realize automobile brake, if piston is subjected to impurity thing influences such as dust in the course of the work, have some setbacks when mobile, certainly will reduce brake efficiency, seizure of piston when serious causes brake failure.Therefore, piston face is usually with the bellows sealing, and in long term production, the assembling of dust cover constantly develops and improves.The assembling of traditional piston dust cover be by hand or instrument such as pliers open dust cover, put into piston then, take off assembly tool, make bellows encase piston, scratch piston face when its shortcoming is the instrument taking-up easily, influence product assembly serviceability, and efficiency of assembling is low.
Summary of the invention
The purpose of this utility model is: at above the deficiencies in the prior art, a kind of automobile brake pincers of being convenient to install the piston dust cover are proposed, and special-purpose piston dust cover air blowing assembling device.
In order to reach above purpose, the automobile brake pincers of being convenient to install the piston dust cover that the utility model provides comprise braking clamp body, it is characterized in that having an inlet channel on the described braking clamp body, described inlet channel one end is connected with braking clamp body cylinder hole, and the other end is in communication with the outside.Can utilize the existing fuel feed hole in braking clamp body lower end as inlet channel.
The utility model also provides the piston dust cover air blowing assembling device of above-mentioned automobile brake pincers, it is characterized in that comprising braking clamp body positioning clamping device, blowning installation, and the inflatable mouth of described blowning installation is corresponding with the inlet channel air inlet of braking clamp body.
Operation principle of the present utility model is as follows: during the assembling beginning, with finger piston packing is embedded in braking clamp body (aperture the is second groove on the lower side) seal groove, the piston dust cover embeds in the dustproof groove of braking clamp body (aperture is first groove on the lower side), take piston to be placed on the piston dust cover then, make the piston bottom surface cover piston dust cover interior circle suitable for reading, the braking clamp body lower end fuel feed hole entrance pressure air that contracts, the inside and outside pressure differential that forms in braking clamp body cylinder hole, utilize dust cover to be rubber parts, the principle that can stretch, the piston dust cover is opened, prolong on the outside piston cylinder and move, encase outside piston.Use push rod push piston endoporus bottom surface again, when piston moves to bottom, braking clamp body cylinder hole, make piston dust cover inner edge embed piston dust cover inner ring, promptly finish assembling.
As seen the utility model is skillfully constructed, the assembling simple and fast, and the efficient height, and can not influence product assembly serviceability because of scratching piston face.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model caliper schematic diagram.
Fig. 2 is the utility model air blowing assembling device schematic diagram 1.
Fig. 3 is the utility model air blowing assembling device schematic diagram 2.
Fig. 4 is the utility model air blowing assembling device schematic diagram 3.
The specific embodiment
This example is that example describes the utility model with the brake piston dust cover device of automotive brake.
The automobile brake pincers of present embodiment as shown in Figure 1, comprise braking clamp body 1, and its improvements are to have an inlet channel 3 on the braking clamp body 1, and described inlet channel 3 one ends are connected with braking clamp body cylinder hole 2, and the other end is in communication with the outside; The end that inlet channel is in communication with the outside has air inlet hydraulic quick coupler 31.In this example, inlet channel 2 is the lower end fuel feed hole of braking clamp body 1.
As Fig. 2, Fig. 3, shown in Figure 4, the piston dust cover air blowing assembling device of the utility model automobile brake pincers is formed and is comprised braking clamp body positioning clamping device and blowning installation, and the inflatable mouth of blowning installation is corresponding with the air inlet (lower end fuel feed hole) of braking clamp body 1; The inflatable mouth of this blowning installation has and cooperates 31 the hydraulic quick coupler 4 of giving vent to anger with the air inlet hydraulic quick coupler of braking clamp body.In this example, the braking clamp body positioning clamping device comprises: be fixed on the guide rail 6 on the base 5, the locating rack 7 of band alignment pin 71 and the hold-down mechanism 8 with pressure head 81, described locating rack 7 is slidingly matched with guide rail 6.Among the figure, 9 is piston, and 10 is the piston dust cover, and 11 is piston packing.
Assembling back is as Fig. 4, and piston packing embeds in the braking clamp body seal groove, the piston braking clamp body cylinder hole of packing into, and the piston upper groove embeds piston dust cover inner ring, and its outer ring embeds braking clamp body and prevents dust in the groove.
Utilize the detail operations process of this assembling device as follows:
