Abstract
The utility model relates to a pressing device which comprises a pressing base and a slide block, wherein a lug boss is arranged on the pressing base; an inclined surface or an inclined slot is arranged outside the lug boss; one side surface of the slide block is matched with the outer side of the lug boss; the other side surface of the slide block is fixedly connected with a pressing plate; the inclined surface or the bottom of the inclined slot outside the lug boss inclines towards the pressing plate; an inner threaded hole with an axis inclining toward the pressing plate is formed in the upper surface of the slide block; the inner threaded hole extends from the upper surface of the lug boss to the interior of the lug boss; a compressed reset spring is mounted under the slide block; and the pressing base and the slide block are connected through a bolt or screw matched with the inner threaded hole. The pressing device has the advantages of being simple in structure principle, strong in practicability, low in cost, suitable for application and popularization, and capable of accurately transferring a pressing force, and meeting the basic demand on the pressing device.
Description
Technical field
The utility model relates to a kind of hold down gag.
Background technology
Necessary mechanism when hold down gag is the design frock, hold down gag requires the clamping force size suitably.The automaticity of hold down gag should adapt with the production lot of workpiece.Work piece production is bigger in batches, allows the clamping device that design is more complicated, efficient is high.Compaction process does not change the tram that occupies behind the workpiece location.Requirement technology is good, and usability is good.Can transmit thrust accurately.This device can satisfy the basic demand to hold down gag.
The utility model content
The purpose of the utility model is to provide a kind of hold down gag that is applicable to box parts processing.
The technical scheme that the utility model adopts is: a kind of novel hold down gag; Comprise pressed seat and slide block; Said pressed seat has a boss, and the outside of said boss is the inclined-plane or is skewed slot that the side of said slide block and the boss outside are complementary; The another side and the pressure strip of slide block are fastenedly connected; The inclined-plane in the said boss outside or the slot part bottom surface of skewed slot tilt to the direction of pressure strip, and said slide block upper surface has the internal thread hole that axis tilts to the pressure strip direction, and said internal thread hole extends to boss inside from the upper surface of boss; The below of said slide block is equipped with compressed back-moving spring, and said pressed seat and slide block are through being connected with bolt or screw that internal thread hole is complementary.
The inclined-plane in the axis of said internal thread hole and the boss outside or the slot part bottom surface of skewed slot are parallel.
The beneficial effect of the utility model is:
1, structural principle is simple, and is practical;
2, with low cost, be fit to apply;
3, thrust can be transmitted accurately, basic demand can be satisfied hold down gag.

The specific embodiment
Embodiment: shown in Fig. 1-3: a kind of hold down gag; Comprise pressed seat 1 and slide block 2; Said pressed seat 1 has a boss 3, and the outside of said boss 3 is the inclined-plane or is skewed slot that the side of said slide block 2 and boss 3 outsides are complementary; The another side of slide block 2 and pressure strip 4 are fastenedly connected; The inclined-plane in said boss 3 outsides or the slot part bottom surface of skewed slot tilt to the direction of pressure strip 4, and said slide block 2 upper surfaces have the internal thread hole 5 that axis tilts to the pressure strip direction, and said internal thread hole 5 extends to boss 3 inside from the upper surface of boss 3; The below of said slide block 2 is equipped with compressed back-moving spring 6, and said pressed seat 1 and slide block 2 are through being connected with bolt or screw that internal thread hole 5 is complementary.
The inclined-plane in the axis of said internal thread hole 5 and boss 3 outsides or the slot part bottom surface of skewed slot are parallel.
The restrained workpiece of an end 7 is withstood in the outside of pressure strip 4, and with bolt on the slide block 2 or screw precession internal thread hole 5, thereby slide block 2 drives pressure strip 4 oblique motions down with oblique motion down and workpiece 7 is compressed.After completion of processing, bolt or screw are unclamped, under the effect of back-moving spring 6, slide block 2 will automatically reset with pressure strip 4.
