Abstract
The utility model relates to a self-adaptive blank contour clamping mechanism which includes a clamp body and is characterized in that a linear cylinder is mounted below the clamp body; a piston of the linear cylinder is connected with a pull rod shaft; the upper end of the pull rod shaft penetrates the clamp body and extends out of the upper surface of the clamp body; a pull rod is arranged at the top of the pull rod shaft; the pull rod is arranged in the radial direction of the pull rod shaft and protrudes out of the circumferential surface of the pull rod shaft; the end part of the pull rod is a circular arc; a bracket base is mounted on the upper surface of the clamp body; a groove is formed in the middle of the bracket base; clamp claws are oppositely arranged on right and left sides inside the groove and on the opposite sides of the pull rod shaft; circular arc-shaped grooves are formed on the surfaces of the opposite sides of the clamp claws; the grooves are matched with the end part of the pull rod; and the bracket base is fixed with the clamp body through hinged bolts on two sides of the bracket base. The self-adaptive blank contour clamping mechanism uses the cylinder to pull down so as to drive the clamp claws and the bracket to move and tightly clamp a workpiece, thereby solving the problem that the machining surface of the workpiece can not be clamped tightly from the front side.
Description
Technical field
The utility model relates to a kind of anchor clamps, especially a kind of machining self adaptation folder blank shape mechanism that is used for.
Background technology
Before die casting class machine components are processed on lathe usually all need with part on workbench through 3 centerings, confirmed to fix behind the locus of workpiece, cutter, pressing plate and press folder, and then carried out machining.When clamping tool for machine work designed, running into the surface through regular meeting needed processing, but can't positively clamp around the machined surface, can't find the blank part of available front pressure point.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art, provides a kind of self adaptation to press from both sides blank shape mechanism, and having solved the workpiece machined surface can't the positive problem that clamps.
According to the technical scheme that the utility model provides, said self adaptation is pressed from both sides blank shape mechanism, comprises clamp body; Characteristic: the straight line oil cylinder is installed below said clamp body; The piston rod of straight line oil cylinder is connected with pull rod shaft, and the upper end of said 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; Said pull bar is along the periphery setting that radially protrudes from pull rod shaft of pull rod shaft, and the end of said pull bar is circular arc; Upper surface mounting bracket seat at said clamp body; Centre at said carrier base is provided with groove, and the left and right sides is oppositely arranged jaw in the groove, and said 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 said groove matches with the end of pull bar.
Said carrier base is fixed through the articulation hole bolt and the clamp body of carrier base both sides.
Said jaw is installed on the carrier base through bearing pin, and jaw can bearing pin be that the center is rotated.
The described self adaptation of the utility model folder blank shape mechanism adopts oil cylinder drop-down, and what drive jaw and carrier base moves clamping work pieces, and having solved the workpiece machined surface can't the positive problem that clamps.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with concrete accompanying drawing the utility model is described further.
Like Fig. 1 ~ shown in Figure 2: self adaptation folder blank shape mechanism comprises straight line oil cylinder 1, pull rod shaft 2, clamp body 3, articulation hole bolt 4, carrier base 5, bearing pin 6, jaw 7, pull bar 8, workpiece 9 etc.
The utility model comprises clamp body 3; Straight line oil cylinder 1 is installed below clamp body 3; The piston rod of straight line oil cylinder 1 is connected with pull rod shaft 2, and the upper end of said pull rod shaft 2 is passed clamp body 3 and stretched out the upper surface of clamp body 3, and the top of pull rod shaft 2 is provided with pull bar 8; Said pull bar 8 is along the periphery setting that radially protrudes from pull rod shaft 2 of pull rod shaft 2, and the end of said pull bar 8 is circular arc;
At the upper surface mounting bracket seat 5 of said clamp body 3, said carrier base 5 is spacing with clamp body 3 through the articulation hole bolt 4 of carrier base 5 both sides; Centre at said carrier base 5 is provided with groove, and the left and right sides is oppositely arranged jaw 7 in the groove, and said jaw 7 is installed on the carrier base 5 through bearing pin 6, and jaw 7 can be rotated for the center by bearing pin 6; Said jaw 7 is arranged on the relative both sides of pull rod shaft 2, and jaw 7 relative side surfaces are provided with circular groove, and said groove matches with the end of pull bar 8.
The course of work of the utility model: after workpiece 8 is had good positioning; Straight line oil cylinder 1 is drop-down, and it is drop-down to drive pull rod shaft 2, the pull bar 8 at pull rod shaft 2 tops and the groove fit of jaw 7 relative sides; Thereby two jaws 7 are that the center is rotated with bearing pin 6 about driving, and two jaws 7 clip to the blank wall; At this moment,, therefore can adjust the clamping angle and the position of jaw 7 automatically, lock articulation hole bolt 4 then, make carrier base 5 fixing owing to have the free gap between carrier base 5 and the articulation hole bolt 4.This reality can't the positive problem that clamps with the novel workpiece machined surface that solved.
