Abstract
The invention discloses a pneumatic fixture. The pneumatic fixture comprises a case body and a main shaft arranged in the case body, wherein an external disc is arranged at the front end of the main shaft, and is connected with a fixture body through a fastening component; the rear end of the case body is connected with a cylinder through a flange; a telescopic rod of the cylinder is located in the main shaft and the diameter of the main shaft is larger than that of the telescopic rod; the telescopic rod of the cylinder is connected with a push rod; a circular hole is configured on the fixture body; and the push rod with the same diameter to the circular hole passes through the circular hole. By using the pneumatic fixture disclosed by the invention, the fixture body is driven to rotate by the main shaft; when the main shaft is rotated, the cylinder does not rotate, so that the cylinder is not liable to damage, the service life is prolonged, the cylinder can be prevented from being frequently replaced, and the cost of processing mechanical parts can be reduced.
Description
Technical field
The present invention relates to a kind of anchor clamps, in particular a kind of air-actuated jaw.
Background technology
At present, along with improving constantly of mechanization degree, people add the requirement in man-hour to part and also improve constantly; The traditional mechanical part is in the process of processing; Part fixedly the time, is needed manually hold out against with push rod, and the power of engaging is difficult to assurance like this; When push rod top too tight,, workpiece is easy to cause distortion if being thin-wall part; When the too pine on push rod top, clamping workpiece is not tight, is prone to defective work, when workpiece occurring when loosening, is prone to safety problem, and so not only labour intensity is big and production efficiency is lower.The appearance of air-actuated jaw can be good at solving the above problems; But the air-actuated jaw that uses at present; The rotation of main shaft can drive the rotation of cylinder, causes the damage of cylinder, seriously shortens the service life of cylinder; Make the cylinder of air-actuated jaw need frequent change, increased the machine components cost of processing.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed the non-damageable air-actuated jaw of a kind of cylinder.
Technical solution of the present invention is achieved in that a kind of air-actuated jaw, comprises casing and main shaft, and said main shaft is located in the casing, and the front end of said main shaft is provided with outer disc; Said outer disc is connected with clamp body through securing member; The rear end of said casing is connected with cylinder through flange; The expansion link of said cylinder is positioned at main shaft, and the diameter of main shaft is greater than the diameter of expansion link; The expansion link of said cylinder links to each other with push rod; Have circular hole on the said clamp body; Said push rod passes circular hole, and the diameter of circular hole is identical with the diameter of push rod.
Preferably, the other end of said push rod links to each other with push rod; Said push rod outside is provided with presses cover.
Preferably, said securing member is a screw bolt and nut.
Preferably, said flange is fixedly connected with casing through extension bar.
Preferably, said extension bar is provided with four.
Preferably, said push rod is threaded with push rod.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Air-actuated jaw of the present invention, during work, because the front end of main shaft is provided with outer disc, outer disc is connected with clamp body through securing member, and main shaft rotates and drives the clamp body rotation; Because the rear end of casing is connected with cylinder through flange, the expansion link of cylinder is positioned at main shaft, and the diameter of main shaft is greater than the diameter of expansion link, and the expansion link of cylinder links to each other with push rod; Have circular hole on the clamp body, push rod passes circular hole, and the diameter of circular hole is identical with the diameter of push rod; When main shaft rotated, cylinder can not rotate, and makes cylinder not fragile; Increase the service life of cylinder, avoided the frequent change of cylinder, reduced the machine components cost of processing.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the structural representation of air-actuated jaw of the present invention;
Accompanying drawing 2 is an air-actuated jaw user mode sketch map of the present invention;
Wherein: 1, casing; 2, main shaft; 3, outer disc; 4, clamp body; 5, bolt; 6, nut; 7, flange; 8, cylinder; 9, extension bar; 10, expansion link; 11, push rod; 12, circular hole; 13, push rod; 14, press cover; 15, workpiece.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Of the present invention a kind of air-actuated jaw shown in accompanying drawing 1 comprises casing 1 and main shaft 2, and said main shaft 2 is located in the casing 1, and the front end of said main shaft 1 is provided with outer disc 3; Said outer disc 3 is connected with clamp body 4 through securing member; Said securing member is bolt 5 and nut 6; The rear end of said casing 1 is connected with cylinder 8 through flange 7; Said flange 7 is fixedly connected with casing 1 through four extension bars 9; The expansion link 10 of said cylinder 8 is positioned at main shaft 2, and the diameter of main shaft 2 is greater than the diameter of expansion link 10; The expansion link 10 of said cylinder 8 links to each other with push rod 11; Have circular hole 12 on the said clamp body 5; Said push rod 11 passes circular hole 12, and the diameter of circular hole 12 is identical with the diameter of push rod 11; The other end of said push rod 11 links to each other with push rod 13 through being threaded; Said push rod outside is provided with presses cover 14.
Like accompanying drawing 2 described a kind of air-actuated jaws of the present invention, in use, workpiece 15 is installed on the clamp body 4, start cylinder 8; This moment, cylinder 8 promotion push rods 11 made push rod 13 together with clamping sleeve 14 workpiece 15 compressed, and main shaft 2 rotates and drives clamp bodies 4 rotations; When main shaft 2 rotated, cylinder 8 can not rotate, and makes cylinder 8 not fragile; Increase the service life of cylinder, avoided the frequent change of cylinder, reduced the machine components cost of processing; After workpiece 15 processes, shifter cylinder 8, cylinder 8 pulls back push rod 11, push rod 13 and clamping sleeve 14 from workpiece 15 together, can unload workpiece 15 like this.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
