Abstract
The invention relates to the technical field of mechanical fixtures, in particular to a workpiece fixture for a multi-functional machine tool. A workpiece or a mold is arranged on the working surface of the machine tool to be fastened. The workpiece fixture comprises a pressing plate main body and a T-shaped sliding block, wherein a stepped groove with a larger upper groove and a smaller lower groove is longitudinally formed in the middle of the pressing plate main body; and the T-shaped sliding block is arranged in the upper groove of the stepped groove. The workpiece fixture is characterized by also comprising a movable base plate on which a plurality of tapped holes with different sizes are formed. The workpiece fixture has the advantages that: the workpiece at any position on a work bench can be firmly fixed; the extended pressing plate does not need replacing; the conventional fixing time is shortened; the workpiece fixture is simple, and easy to operate, is suitable for different sizes, and works stably and accurately; equipment machine tool body and mounting holes are not damaged; the phenomenon that parts drop out does not exist; the workpiece fixture is difficult to damage and deform; the workpiece fixture is smooth and labor-saving when regulating gaps; the strength and the compressive resistance are increased; the clamping pressure is uniform; the shock resistance is high; and the workpiece cannot be loosened or displaced.
Description
[technical field]
The present invention relates to the mechanical clamp technical field, a kind of specifically workpiece or mould are installed to the multifunction machine work piece holder that plays the role of fastening on the working face of lathe.
[background technology]
Pressing plate be the simplest in the machinery industry also be the most frequently used anchor clamps, traditional flat shape pressing plate, with the supporting use of cushion block because the thickness of workpiece difference, must corresponding replacing cushion block, do not have suitable cushion block at hand and bother with regard to Chang Yin.Improved stairstepping cushion block can be avoided this contradiction, but owing to be separated with pressing plate, the trouble that cushion block drops and scatters and disappears takes place easily in use.
China Patent No. is 99206225.X, provide a kind of machine with making things convenient for the pressing plate group, mainly form by pressing plate, last lower liner, cramp and screw, the flank of tooth of lower liner is attached on the tooth bar at the pressing plate back side, last liner is stacked in again on the lower liner, and screw strings together the three in the screw that is screwed in the lathe working face, the upper end of two cramps and the riveted joint of last liner, the T prefix of lower end is across the both sides of groove at the pressing plate outside of belly, and last liner and lower liner are linked on pressing plate.Though it has solved the problem of cushion block, but still also exist many weak points: one, because employing cramp fixed form will go up liner and lower liner links on pressing plate, it is too big to couple together the gap, in use cramp is easy to distortion, loosening, the come off phenomenon of pressing plate of lower liner can occur.The particularly a whole set of pressing plate that is chained together because of carelessness when eminence drops on the ground, cause parts distortion appears, damage after normally practicality, so use very inconvenient; Two, because the size and location of the screwed hole that workbench is provided with are changeless, when using above-mentioned pressing plate fixedly, often match with screw because of the screwed hole that does not have the optimum position on the workbench, and can't fixation workpiece, can only need to change the extended type pressing plate fixes, thereby further increased the cost of manufacture of product, also brought a series of use inconvenience simultaneously; Three, because the pressing plate front end is that line contacts with the contact-making surface of workpiece, so loosening and offset phenomena appear in the workpiece that is easy to cause fixing.
[summary of the invention]
Task of the present invention overcomes the deficiencies in the prior art exactly, provide can stationary work-table on the workpiece of any position, need not to change the extended type pressing plate, multifunction machine work piece holder more convenient to use.
The present invention adopts following technical proposals: a kind of multifunction machine work piece holder, comprise pressing plate main body, T shape slide block, pressing plate main body central longitudinal is descended the little step trough of groove greatly to having groove, T shape slide block is installed in the last groove of step trough, it is characterized in that: also comprise and move backing plate, open the screwed hole of a plurality of different sizes on the described mobile backing plate.
Described pressing plate body front end flexibly connects front stall, and the front stall bottom is that face contacts with the workpiece contact-making surface, and described front stall lower surface is a non skid matting.
The described groove two sides of going up have slide block slot, and the both sides end face down of described T shape slide block goes into to connect slide block slot.
Described pressing plate main body tail end flexibly connects base, and the base bottom is the plane.
Described slide block slot is an arc, and the last trench bottom of described step trough is a curved surfaces, and curved surfaces is provided with the semicircular arc groove, the lower surface of the slide block semicircular arc groove that is connected.
Beneficial effect of the present invention:
One, shorten tradition clamp the time, simple to operation, adapt to different size work, stable and accurately, equipment lathe bed and installing hole do not have damage, the part phenomenon that drops generally can not take place, not fragile yet and the distortion, very smooth, laborsaving during spacing, gain in strength and compressive resistance, cramping is even, and shock resistance is good, loosening and the displacement of workpiece can not occur, increase work efficiency greatly;
Two, designed one and moved backing plate, make pressing plate of the present invention can stationary work-table on the workpiece of any position, need not to change the extended type pressing plate, more convenient to use;
Three, the pressing plate body front end flexibly connects front stall, is that face contacts with the contact-making surface of workpiece like this, thus more firm fixation workpiece.
In addition, the present invention makes simply, and cost is low, and performance is good, is worthy of popularization.
