Summary of the invention

The present invention is the workpiece fast positioning clamping device that a kind of adjustable clamping force will be provided, this device can be by workpiece fast positioning clamping, assurance processing dimension is accurate, not yielding, after clamping work pieces, can regulate position location and clamping force, have easy to use, time and labour saving is laborsaving, accurately certainly fast feature reliably, the location that is specially adapted to the workpiece with strain clamps.

For achieving the above object, the technical solution used in the present invention is: a kind of workpiece fast positioning clamping device of adjustable clamping force, comprise base, axle bed, guide holder, clamping lever, the axis of guide, setting-up screw, rear fixed stop, on base, surface rear end is provided with axle bed, front end one side is provided with guide holder, above opposite side by fixed stop after the adjustable connection of lock-screw, the rear end face of base is provided with adjusting boss, regulate between boss and rear fixed stop and be provided with adjusting screw(rod), in guide holder, be flexibly connected the axis of guide, the axis of guide is rotary with setting-up screw in rear end, clamping lever rear end is connected with axle bed with adjusting nut by bolt, clamping lever lower end is provided with clamping plate, clamping plate and setting-up screw head contact-making surface are provided with lozenges and lower lozenges, between setting-up screw and guide holder, be provided with Compress Spring.

In the time of locating clip clamping of workpieces, under clamping plate, the contact of lozenges or upper lozenges and setting-up screw head outer face is connected, contacts and is connected after clamping plate with rear fixed stop front end face.

Setting-up screw is flanged (FLGD) outer-hexagonal bolt, and adjusting nut is manual adjustments nut.Upper lozenges and lower lozenges difference between high and low are 0.5～1.0mm.

The present invention adopts the beneficial effect that technique scheme produces to be:

(1) can be to workpiece fast positioning clamping by clamping lever, guarantee that processing dimension is accurate, not yielding;

(2) realize the fine setting of position location and clamping force by the upper and lower lozenges on the clamping plate of clamping lever

(3) eliminate and regulate gap and the axis of guide is resetted by Compress Spring.

(4) by the position of fixed stop after regulating, the clamping force of the workpiece after adjustable gripping;

(5) adopt flanged (FLGD) outer-hexagonal bolt as setting-up screw, can conveniently realize and clamp rear position location and the clamping force of regulating, the location that is specially adapted to the workpiece with strain clamps.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment, the invention will be further described.

As shown in Figure 1 to Figure 3, a workpiece fast positioning clamping device for adjustable clamping force, comprises base 1, axle bed 12, guide holder 8, clamping lever 2, the axis of guide 3, setting-up screw 4, Compress Spring 5, bolt 6, adjusting nut 7, rear fixed stop 9, adjusting screw(rod) 16, lock-screw 15, locking nut 17.

On base 1, surface rear end is provided with axle bed 12, front end one side is provided with guide holder 8, above opposite side by fixed stop 9 after the adjustable connection of lock-screw 14, the rear end face of base 1 is provided with and regulates boss 14, regulate between boss 14 and rear fixed stop 9 and be provided with adjusting screw(rod) 16, the interior flexible connection axis of guide 3 of guide holder 8, the axis of guide is rotary with setting-up screw 4 in 3 rear ends, clamping lever 2 rear ends are connected with axle bed 12 with adjusting nut 7 by bolt 6, clamping lever 2 lower ends are provided with clamping plate 10, clamping plate 10 is provided with lozenges 13 and lower lozenges 11(Fig. 4 with 4 contact-making surfaces of setting-up screw), between setting-up screw 4 and guide holder 8, be provided with Compress Spring 5.

In the time of locating clip clamping of

workpieces

19,10 times lozenges 11 of clamping plate or upper lozenges 13 are connected with setting-up screw 4 head outer face contacts, and clamping plate 10 is connected with rear fixed stop 9 front end face contacts below.Setting-up screw 4 is flanged (FLGD) outer-hexagonal bolt, and adjusting nut 7 is manual adjustments nut.
