Abstract

The invention discloses a positioning and clamping mechanism of a welding fixture of an automobile stamping piece, which comprises an installing seat which is installed on a bottom board of the welding fixture; one end of the installing seat is provided with a locking cylinder, and the other end of the installing seat is fixed with a supporting block; a piston rod of the locking cylinder penetrates through the installing seat and the supporting block; a positioning pin which is positioned towards a positioning hole of the stamping piece is fixed on the extending end of the piston rod of the locking cylinder; the upper end of the installing seat is hinged with a bent pressing block; the lower end of the pressing block is buckled outside the supporting block; and a hinge mechanism is also fixed on the piston rod of the locking cylinder and is hinged with the upper end of the bent pressing block through a connecting rod. According to the invention, one locking cylinder is adopted for simultaneously realizing positioning and clamping functions; the manufacturing cost of the fixture is reduced; and an enough space for operation is reserved for a welding gun, so as to be convenient for operation of workers and favorable for enhancing production efficiency.

Description

The positioning and clamping mechanism of welding automobile stamping workpiece fixture
Technical field
The present invention relates to positioning clamping device, is mainly a kind of positioning and clamping mechanism of welding automobile stamping workpiece fixture.
background technology
At present, in auto manufacturing, qualified in order to guarantee stamping parts welding product, the labour intensity that reduces workman improves the production efficiency of factory simultaneously, extensively adopts Pneumatic welding clamp.But in these weld jigs, generally adopted the detent mechanism mode separated with clamp mechanism, this makes clamp structure relative complex, has increased fixture manufacturing cost; Complicated clamp structure also makes welding gun operating space little simultaneously, is not easy to workman's operation; Positioning clamping separation also makes efficiency of movement reduce, and has limited the raising of production efficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of positioning and clamping mechanism of welding automobile stamping workpiece fixture, and it uses a locking cylinder can realize location clamping function simultaneously, has reduced the manufacturing cost of fixture; For welding gun, reserved enough operating spaces, be convenient to workman's operation, be conducive to enhance productivity.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of positioning and clamping mechanism of welding automobile stamping workpiece fixture, include the mount pad being arranged on weld jig base plate, it is characterized in that: on described mount pad, one end is provided with locking cylinder, on the other end of mount pad, be fixed with back-up block, the piston rod of locking cylinder is through mount pad and back-up block, the external part of the piston rod of described locking cylinder is fixed with the alignment pin towards stamping parts locating hole location, described mount pad upper end is hinged with a bending briquetting, described briquetting lower end is buckled in outside described back-up block, on the piston rod of described locking cylinder, be also fixed with linkage, described linkage is hinged by connecting rod and bending briquetting upper end.
Described bending briquetting is step shape.
Mode of operation of the present invention is:
During design, by calculating, choose the locking cylinder that stroke is suitable, during welding work pieces, workpiece is placed on back-up block, the piston rod of locking cylinder stretches out, drive alignment pin to be inserted in the locating hole of workpiece and locate plate, drive the linkage being connected with piston rod to move simultaneously, make to be fixed on briquetting on linkage by Work-sheet pressing on back-up block, now locking cylinder locking prevents that piston rod from returning and alters workpiece and get loose, thereby the location of realizing workpiece clamps; After having welded, locking cylinder piston rod is retracted, and drives the linkage action being connected with piston rod, and the briquetting that makes to be fixed on linkage unclamps, and drives alignment pin to exit locating hole simultaneously, thereby unclamps workpiece, to take out the workpiece welding.
In the present invention, use a clamping cylinder to realize location clamping function simultaneously, reduced and used the quantity of clamping cylinder and location to clamp required transfer block structure, also shortened location and clamped required actuation time.
Advantage of the present invention is:
The present invention adopts a locking cylinder can realize location clamping function simultaneously, has reduced the manufacturing cost of fixture; For welding gun, reserved enough operating spaces, be convenient to workman's operation, be conducive to enhance productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Referring to Fig. 1, the positioning and clamping mechanism of welding automobile stamping workpiece fixture, include the mount pad 1 being arranged on weld jig base plate, on described mount pad 1, one end is provided with locking cylinder 2, on the other end of mount pad 1, be fixed with back-up block 3, the piston rod of locking cylinder 2 is through mount pad 1 and back-up block 3, the external part of the piston rod of described locking cylinder 2 is fixed with the alignment pin 4 towards stamping parts locating hole location, there is a bending briquetting 6 described mount pad 1 upper end hinged 7, described briquetting 6 lower ends are buckled in outside described back-up block 3, on the piston rod of described locking cylinder 2, be also fixed with linkage 5, described linkage 5 is hinged by connecting rod and bending briquetting 6 upper ends.On mount pad 1, have bar-shaped trough, for linkage 5 and the binding site of piston rod, in bar-shaped trough, move.
