Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of and can ensure that clamping force is invariable and adjust presser type clamping device easy, simple to operate.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals.
A kind of constant force presser type clamping device, comprise base, backing plate, end plates, guide plate, clamping plate, screw rod and holding down assembly, described backing plate is fixedly mounted on described base, described base upper surface is provided with a blind hole, the described backing plate corresponding with described blind hole is provided with the first through hole, described guide plate is fixedly mounted on described backing plate, and bottom be provided with one for described clamping plate move left and right guiding and the gathering sill of right openings, guide plate is also provided with second through hole of side with plane of above-below direction, be provided with by two sections of circular arcs in the middle part of described clamping plate, the polygon groove for holding down assembly described in controlling that one step and two oblique lines are formed, right-hand member is provided with the opening rectangular channel snapped in for the end of described screw rod to the right, described end plates are fixedly mounted on the right side of described guide plate, the middle part of end plates is provided with a screwed hole screwed with described screw rod, describedly hold down assembly in installing blind, and be upward through the first through hole, polygon groove, second through hole, finally stretch out the end face of described guide plate.
As preferred technical scheme, described holding down assembly comprises split washer, stretching screw, traveller, spring and two steel balls, described traveller comprises top and is provided with one for the connecting portion of installing described stretching screw and the guide part be slidably matched with blind hole, junction between connecting portion and guide part is provided with two for installing the straight trough of two described steel balls, the side of connecting portion is provided with the second plane of one and described plane contact, described spring fitting is between blind hole and guide part, when namely described screw rod precession is moved to the left, described clamping plate is also to moving to left and depressing two described steel balls, thus the plate type part driving described traveller slide downward and be clamped between described split washer and described guide plate.
Therefore the beneficial effect of constant force presser type clamping device of the present utility model is: after clamping plate slides onto left and depressed completely by two described steel balls, the clamping force produced workpiece between split washer and guide plate maintains a steady state value, when needs increase or reduce clamping force, only need to adjust stretching screw position, namely the distance between split washer and traveller end face is adjusted, thus this device can not only ensure that clamping force is constant, and it is fast easy to adjust, in addition, rotary screw can realize Workpiece clamping or unclamp, thus clamping workpiece is convenient, and structure is simple.
