Description
Technical field
The invention belongs to technical field of tooling clamps, specifically, particularly to a kind of double air-cylinder type detent mechanisms.
Background technology
Automobile hind axle assembly is made up of crossbeam, trailing arm, spring base, bushing pipe, parking brake cable support, oil tube bracket and amortisseur mounting seat etc., it is symmetrically welded trailing arm at the two ends of crossbeam, each trailing arm welds bushing pipe, parking brake cable support, amortisseur mounting seat and oil tube bracket successively.Welding when, operation break-down is needed respectively crossbeam, trailing arm, spring base, bushing pipe etc. to be positioned by multiple frocks.Existing bushing pipe positioning tool structure is complicated, takes up room big, and cost is high, para-position difficulty, and the steadiness positioned is poor so that welding quality is difficult to ensure that, does not reaches the requirement of uniform production.
Summary of the invention
The technical problem to be solved is to provide a kind of simple in construction, the most double air-cylinder type detent mechanism.
Technical scheme is as follows: a kind of double air-cylinder type detent mechanisms, it is characterized in that: fixed guide cylinder on the cylinder body of the first cylinder, guide cylinder is steel structure, the piston rod of the first cylinder stretches in guide cylinder straight up, and be connected with the lower end of guide pillar, alignment pin is installed on the top of described guide pillar, alignment pin can stretch out outside guide cylinder, being provided with locating ring in the periphery of described alignment pin, this locating ring is installed on the end face of guide cylinder；Equipped with the second cylinder on described guide cylinder, the axial line of the second cylinder and the axial line of the first cylinder are parallel, and the piston rod of described second cylinder stretches out straight up, and is connected with one end of pressure arm, fixing pressure head in the bottom surface of the pressure arm other end, this pressure head is positioned at the surface of alignment pin；
Conical surface transition is passed through between end face and all sides of described alignment pin, the bottom of this alignment pin is formed with short column, short column embeds in the adaptive groove that guide pillar upper end is offered, up big and down small two-part stepped hole is offered at the center of described alignment pin, this stepped hole wears countersunk head stay bolt, the lower end of described countersunk head stay bolt is stretched in guide pillar, alignment pin and guide pillar is fixed together；
"T"-shaped groove is offered in the lower end of described guide pillar, and it is provided with joint between the piston rod of guide pillar and the first cylinder, described joint is bolt arrangement, the head boss of this joint snaps in the "T"-shaped groove of guide pillar lower end, both snap-fit engagement, the lower end of joint is connected with the piston rod thread of the first cylinder, and by nut check, nut is close to the end face of the first cylinder piston rod.
Use above technical scheme, the when of the automobile hind axle assembly bushing pipe of location, first bushing pipe is placed on locating ring, then the piston rod driving the first cylinder protrudes upward, guide pillar is made to move upward together with alignment pin, alignment pin stretches in bushing pipe and positions, make bushing pipe planar will not produce to rock, then the piston rod action of the second cylinder is driven, the piston rod making the second cylinder drives pressure arm to move downward, until pressure head compressing is at the end face of bushing pipe, pressure head and locating ring match, the clamping to bushing pipe can be realized compress, in conjunction with the alignment pin in bushing pipe, may insure that the steadiness that bushing pipe positions, so welding quality between bushing pipe and trailing arm is secure, the requirement of uniform production can be met.
The present invention uses double cylinders providing power, and parts are few, and overall structure is simple, compact, it is easy to assembling, compact, takes up room little, low cost, and manipulates conveniently.
By conical surface transition between alignment pin end face and all sides, this conical surface plays the effect of guiding, makes alignment pin enter bushing pipe and is easier to；Alignment pin lower end is inlayed with guide pillar and is coordinated, and the countersunk head stay bolt worn by center is fastened, and the fastness on the one hand connected is good, and alignment pin will not loosen, and on the other hand, the head of countersunk head stay bolt does not exposes, and will not produce with pressure head and interfere.
Owing to guide pillar is limited can only move at above-below direction by guide cylinder, therefore joint is used to be attached between the piston rod of guide pillar and the first cylinder, make upper end and the guide pillar snap-fit engagement of joint, the piston rod of the lower end of joint and the first cylinder passes through screw threads for fastening, this greatly simplifies the mounting structure between guide pillar and the first cylinder piston rod, disassembling operations is very convenient, quick.
In order to reduce abrasion as much as possible, increasing the service life, be embedded with wear-resisting bushing pipe in the inside of described guide cylinder, described wear-resisting bushing pipe is slidably matched with guide pillar.
In order to simplify structure, it is simple to processing and fabricating and assembling, described pressure head is pane structure, and this pressure head is connected with pressure arm by row's bolt.
Beneficial effect: present inventive concept is ingenious, reasonable in design, implement easily, simple in construction, compact, not only manipulate conveniently, go slick, reliably, and be capable of accuracy and the steadiness of bushing pipe location, being conducive to bushing pipe welded and installed, welding quality is secure, can meet the requirement of uniform production.
