Abstract

The invention discloses a rotary clamping device. The rotary clamping device is used for solving the problems of complexity of power transmission structures, high cost and production retardation of existing clamping devices and comprises an air cylinder and a press board connected with the piston rod of the air cylinder, wherein the piston rod of the air cylinder is circumferentially provided with a spiral groove, the wall of the air cylinder is fixedly provided with a guide pin, the end portion of the guide pin is arranged inside the groove, and the upper surface of the air cylinder is provided with a gasket. The rotary clamping device is simple in structure and can effectively reduce the impact to a workpiece when the air cylinder drives the press board to clamp the workpiece.

Description

Rotating clamp
Technical field
The present invention relates to Machining Technology, be specifically related to a kind of rotating clamp.
Background technology
clamping device, as the clamping and positioning instrument of workpiece, is widely used in the processing and manufacturing of workpiece, and existing clamping device pressing plate adopts cylinder or oil cylinder as power source, by jaw or pressing plate clamping work pieces.If moved by the moving jaw of cylinder or oil cylinder direct tape splicing or pressing plate, in clamping engineering, can produce larger impact to workpiece, be easy to defective work piece surface, for addressing this problem, clamping device generally adopts rack-and-pinion or other drive mechanism transferring power at present, to alleviate the impact of clamping force, but such structure is often more complicated, also inapplicable in small batch workpiece manufacture processing.
Summary of the invention
The invention provides a kind of rotating clamp, to solve, the power transmission arrangment that existing clamping device exists is complicated, cost is high, is unfavorable for the problem of producing.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
Rotating clamp, comprises cylinder and the pressing plate being connected with cylinder piston rod, wherein, at described cylinder piston rod, circumferentially have helical groove, on the casing wall of described cylinder, be fixed with a pilot pin, described pilot pin end is placed in described groove, at described cylinder upper surface, is provided with pad.
Beneficial effect of the present invention: this clamping device moves up and down when clamping or unclamping workpiece at cylinder piston rod band dynamic pressure plate; pilot pin is shored in helical groove; to make cylinder piston rod make crankmotion; like this in cylinder band dynamic pressure plate clamping work pieces process; cylinder piston rod carries out downwards simultaneously and rotatablely moves slowly; until pressing plate clamping work pieces can effectively reduce the percussion to surface of the work that cylinder piston rod directly moves up and down and brings as straight line with dynamic pressure plate, protection workpiece.
Further, the position being connected with piston rod at described pressing plate is provided with compression adjusting nut.As required, compress adjusting nut and there is the effect that regulates clamping force.
Accompanying drawing explanation
Fig. 1 is the structural representation of rotating clamp embodiment of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Rotating clamp as shown in Figure 1, the pressing plate 2 that comprise cylinder 1, is connected with cylinder piston rod, be arranged on the circumferential helical groove of cylinder piston rod 3, one end and be arranged at pilot pin 4 in described helical groove, be arranged at pad 5, setting and the pressing plate of described cylinder upper surface and the compression adjusting nut 6 of piston connecting portion and grain-clamping table 7, the described pilot pin other end is fixed on the casing wall of described cylinder, at described grain-clamping table upper surface, is provided with workpiece locating slot and pressure sensor.
This clamping device moves up and down when clamping or unclamping workpiece at cylinder piston rod band dynamic pressure plate, under the effect of pilot pin, to make cylinder piston rod make crankmotion, like this in cylinder band dynamic pressure plate clamping work pieces process, cylinder piston rod carries out downwards simultaneously and rotatablely moves slowly, until pressing plate clamping work pieces can effectively reduce the percussion to surface of the work that cylinder piston rod directly moves up and down and brings as straight line with dynamic pressure plate.

Claims (2)

1. rotating clamp, comprises cylinder and the pressing plate being connected with cylinder piston rod, it is characterized in that, at described cylinder piston rod, circumferentially have helical groove, on the casing wall of described cylinder, be fixed with a pilot pin, described pilot pin end is placed in described groove, at described cylinder upper surface, is provided with pad.
