Abstract
The invention relates to a self-adaptive blank outline clamping mechanism, which comprises a clamp and is characterized in that a linear cylinder is mounted below the clamp, a piston rod of the linear cylinder is connected with a pull rod shaft, the upper end of the pull rod shaft penetrates through the clamp and extends out of the upper surface of the clamp, a pull rod is arranged at the top of the pull rod shaft and projects over the circumferential surface of the pull rod shaft radially along the pull rod shaft, the end of the pull rod is arc-shaped, a support base is mounted on the upper surface of the clamp, a trough is arranged in the middle of the support base, clamping jaws are oppositely arranged on the left side and the right side in the trough and disposed on two opposite sides of the pull rod shaft, arc-shaped grooves are arranged on surfaces of opposite sides of the clamping jaws and matched with the end of the pull rod, and the support base and the clamp are fixed by reamed hole fitting bolts on two sides of the support base. The cylinder is used for pulling down and driving the clamping jaws and the support base to move so that a workpiece is clamped, and the problem of incapability of clamping the front surface of a machined surface of the workpiece is solved.
Description
Technical field
The present invention relates to a kind of fixture, especially a kind of for machining self adaptation folder blank shape mechanism.
Background technology
Die casting class machine components before processing on lathe, conventionally all need by part on workbench by 3 centerings, be fixed and press folder after determining the locus of workpiece, cutter, pressing plate, and then carry out machining.In the time that clamping tool for machine work designs, often can run into surface needs processing, but cannot positively clamp around machined surface, cannot find the blank part of available front pressure point.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of self adaptation to press from both sides blank shape mechanism, having solved workpiece machined surface cannot the positive problem clamping.
According to technical scheme provided by the invention, described self adaptation is pressed from both sides blank shape mechanism, comprise clamp body, feature: below described clamp body, linear oil cylinder is installed, the piston rod of linear oil cylinder is connected with pull rod shaft, and the upper end of described pull rod shaft is passed clamp body and stretched out the upper surface of clamp body, and the top of pull rod shaft is provided with pull bar, described pull bar is the periphery setting for pull rod shaft along the radial convex of pull rod shaft, and the end of described pull bar is circular arc; At the upper surface mounting bracket seat of described clamp body, centre at described carrier base is provided with groove, and in groove, the left and right sides is oppositely arranged jaw, and described jaw is arranged on the relative both sides of pull rod shaft, the surface of the relative side of jaw is provided with circular groove, and described groove matches with the end of pull bar.
Described carrier base is fixed by hinged bolts and the clamp body of carrier base both sides.
Described jaw is arranged on carrier base by bearing pin, and jaw can be rotated centered by bearing pin.
When work, after workpiece is had good positioning, linear oil cylinder is drop-down, drives pull rod shaft drop-down, the groove fit of the pull bar at a pull rod shaft top side relative to jaw, thus drive two jaws in left and right to be rotated centered by bearing pin, two jaws clip to blank wall; Now, owing to there is free gap between carrier base and hinged bolts, therefore can automatically adjust clamping angle and the position of jaw, then lock hinged bolts, carrier base is fixed.
Self adaptation of the present invention is pressed from both sides blank shape mechanism and is adopted oil cylinder drop-down, drives the movement of jaw and carrier base to carry out clamping work pieces, and having solved workpiece machined surface cannot the positive problem clamping.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the A-A cutaway view of Fig. 1.
Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in Fig. 1 ~ Fig. 2: self adaptation folder blank shape mechanism comprises linear oil cylinder 1, pull rod shaft 2, clamp body 3, hinged bolts 4, carrier base 5, bearing pin 6, jaw 7, pull bar 8, workpiece 9 etc.
The present invention includes clamp body 3, linear oil cylinder 1 is installed below clamp body 3, the piston rod of linear oil cylinder 1 is connected with pull rod shaft 2, the upper end of described pull rod shaft 2 is passed clamp body 3 and is stretched out the upper surface of clamp body 3, the top of pull rod shaft 2 is provided with pull bar 8, described pull bar 8 is the periphery setting for pull rod shaft 2 along the radial convex of pull rod shaft 2, and the end of described pull bar 8 is circular arc;
At the upper surface mounting bracket seat 5 of described clamp body 3, described carrier base 5 is spacing with clamp body 3 by the hinged bolts 4 of carrier base 5 both sides; Centre at described carrier base 5 is provided with groove, and in groove, the left and right sides is oppositely arranged jaw 7, and described jaw 7 is arranged on carrier base 5 by bearing pin 6, and jaw 7 can be rotated centered by bearing pin 6; Described jaw 7 is arranged on the relative both sides of pull rod shaft 2, and the side surface that jaw 7 is relative is provided with circular groove, and described groove matches with the end of pull bar 8.
The course of work of the present invention: after workpiece 8 is had good positioning, linear oil cylinder 1 is drop-down, drives pull rod shaft 2 drop-down, the groove fit of pull bar 8 side relative to jaw 7 at pull rod shaft 2 tops, thereby drive two jaws 7 in left and right to be rotated centered by bearing pin 6, two jaws 7 clip to blank wall; Now, owing to there is free gap between carrier base 5 and hinged bolts 4, therefore can automatically adjust clamping angle and the position of jaw 7, then lock hinged bolts 4, make carrier base 5 fixing.This reality and the novel workpiece machined surface that solved cannot the positive problems clamping.
