Further, the right end of the backing plate is provided with locking fixture block.
Compared to the prior art the present invention, has the following advantages and effect:Compressed spring drives lever around lever axis pin
Clockwise oscillation, by connecting rod with clamping of the fixture block realization to workpiece on dynamic pressure plate.When needing to unclamp workpiece, oscillating cylinder band
Moving cam rotates, and overcomes compressed spring resistance counter-clockwise swing, connecting rod that will put away workpiece with dynamic pressure plate by idler wheel activation lever,
Realize the release to workpiece.When pressing plate to be made keeps unclamping the state of workpiece, drive electromagnet action to pull lockplate counterclockwise
It is allowed to contact at face with the backing plate mounted on lever supporting lower end, realizes locking.When clamping force needs adjustment, unscrew adjusting spiral shell
Mother, adjusts the left and right position of adjusting screw rod, then tightens adjusting nut, realizes the adjustment to compressed spring compression degree.Adjust spiral shell
Mother is flange nut, and locking effect is good.Idler wheel is rubber roll, reasonable for structure, and service life is long.The right end of backing plate is provided with lock
Tight fixture block is conducive to the locking to lever positions.The present invention can not only fast implement the clamping and release to workpiece, and clamp
Power is adjustable, reasonable for structure, strong applicability.

Specific implementation mode
The present invention is described in further detail below in conjunction with the accompanying drawings and by embodiment, and following embodiment is to this hair
Bright explanation and the invention is not limited in following embodiments.
As shown in Figure 1, a kind of Workpiece clamping device, it includes bearing support 1, compressed spring 2, hold-down support 3, adjusts spiral shell
