Abstract
The invention discloses a clamping size adjustable automatic clamping device and aims at solving the problem that the existing clamping device is only capable of clamping fixed-size workpieces and thus limited in use. The clamping size adjustable automatic clamping device comprises a cylinder, a first connecting rod, a triangular connecting piece, a second connecting piece, a pressing plate and a clamping platform, wherein the piston rod of the cylinder is connected with one end of the first connecting rod, the other end of the first connecting rod is connected with one end of the triangular connecting piece, the other end of the triangular connecting piece is connected with one end of the second connecting rod, the other end of the second connecting rod is connected with one end of the pressing plate, the middle part of the pressing plate is hinged, the other end of the pressing plate is a clamping end which is matched with the clamping platform to clamp workpieces, the clamping platform is arranged in a sliding chute, and the clamping platform is capable of sliding along the sliding chute and self-locked. The clamping device can be applied to clamping the workpieces of different sizes, and is practical.
Description
Technical field
The present invention relates to Machining Technology, be specifically related to a kind of automatic clamping device of adjustable holding size.
Background technology
in the manufacture processing of workpiece, generally all need clamping device to carry out clamping position to workpiece.Existing clamping device generally can only grip the workpiece of size, and to other workpiece inapplicable, is restricted like this with regard to the use that makes this kind of clamping device.
Summary of the invention
The invention provides a kind of automatic clamping device of adjustable holding size, to solve existing clamping device, can only grip dimension workpiece, use limited problem.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
The automatic clamping device of adjustable holding size, comprise cylinder, first connecting rod, triangle connection element, the second connector, pressing plate and grain-clamping table, the piston rod of cylinder is connected with first connecting rod one end, the other end of first connecting rod is connected with three connector one end, the other end of triangle connection element is connected with one end of second connecting rod, the other end of second connecting rod is connected with one end of pressing plate, the middle part of pressing plate is hinged, the other end of pressing plate is the bare terminal end that coordinates holding workpiece with grain-clamping table, grain-clamping table is arranged in a chute, and grain-clamping table can move and self-locking along chute.
Beneficial effect of the present invention: because this clamping device grain-clamping table is arranged in chute, grain-clamping table can move and self-locking along chute, therefore can change the size of grasping part by the relative position of the bare terminal end of adjusting grain-clamping table and pressing plate, thereby realize the clamping of different size workpiece.To sum up, the workpiece that this clamping device can clamping position different size, possesses practicality.
Further, described grain-clamping table comprises two side direction clamping faces and end clamping face, and two side direction clamping faces become 90
oarrange.This structural design of grain-clamping table is in clamping during cylindrical work, can guarantee in piece-holder process non-sliply, and clamping is stable.
Further, between triangle connection element and cylinder piston rod, be provided with pressing plate back-moving spring.When unclamping workpiece, back-moving spring can make plunger backer automatically reset to pressing plate direction.
Accompanying drawing explanation
Fig. 1 is the structural representation of the automatic clamping device embodiment of adjustable holding size of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
The automatic clamping device of adjustable holding size as shown in Figure 1, comprise cylinder 1, first connecting rod 2, triangle connection element 3, second connects 4, pressing plate 5, grain-clamping table 6, chute 7, workpiece 8 and spring 9, the piston rod of cylinder is connected with first connecting rod one end, the other end of first connecting rod is connected with three connector one end, the other end of triangle connection element is connected with one end of second connecting rod, the other end of second connecting rod is connected with one end of pressing plate, the middle part of pressing plate is hinged, the other end of pressing plate is the bare terminal end that coordinates holding workpiece with grain-clamping table, grain-clamping table is arranged in a chute, grain-clamping table can move and self-locking along chute, described grain-clamping table comprises two side direction clamping faces and end clamping face, two side direction clamping faces become 90
oarrange, between triangle connection element and cylinder piston rod, be provided with pressing plate back-moving spring.
This clamping device operation principle is as follows:
Cylinder piston rod moves upward and drives first connecting rod to move upward, first connecting rod drives triangle connection element one end upwards to swing, and the other end of triangle connection element, to lower swing, makes one end of pressing plate to lower swing by the transmission of second connecting rod, the bare terminal end of pressing plate is put outward, thereby unclamps workpiece; Otherwise cylinder piston rod moves downward, through the transmission of first connecting rod, three connectors and second connecting rod, the bare terminal end of pressing plate is by interior pendulum clamping work pieces.By the diverse location that grain-clamping table is moved to chute, change the space between grain-clamping table and bare terminal end, the clamping size of adjustable work-piece.
Claims (3)
