Description

A kind of presser device

Technical field

The utility model relates to a kind of machine tool accessories anchor clamps, especially refers to a kind of the workpiece of required processing or mould are placed on the table top of lathe, and it is fixed and is convenient to the employed presser device of machine tooling.

Background technology

Existing machine 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, is looked 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.A kind of advanced arch pressing plate is arranged in the import equipment, save cushion block, can push down tilting pressing plate for making screw, introduce a liner therebetween as transition, longitudinally distributing at the pressing plate back side, several can hold the arc pit of liner, the selection that several gears of being combined with of screw and pressing plate are put, but this structure can not be made thinner stepping, is difficult to adapt to changeable installation site in practicality.

For this reason the inventor to have proposed the patent No. be the Chinese utility model patent of 99206225.X, it comprises the pressing plate that vertically has elongated slot and goes here and there and go up the screw that a pair of upper and lower liner compresses usefulness, it is characterized in that pressing plate is arch, respectively there is a row to be the tooth bar of fine and closely woven distribution at its back side along the elongated slot both sides, for profile of tooth cooperates, be that cambered surface cooperates between upper and lower liner between lower liner and pressing plate.Such pressing plate group, structure is terse, upper and lower liner that screw cooperates by a pair of cambered surface and lower liner cooperate with serrate profile between the pressing plate back side, need not just can compress the arch pressing plate that is inclined cross on workpiece and work top by cushion block, and the change in a big way can both adapt to thickness of workpiece.Compare with traditional flat shape pressing plate, avoided to change with the thickness of workpiece change trouble of cushion block.Also because lower liner cooperates with serration between pressing plate, the position of screw in the pressing plate elongated slot can be adjusted accordingly, a kind of arch pressing plate of advanced person is compared in these follow-up jaws equipments, demonstrates the advantage that the said goods more can adapt to various installation sites.But the shortcoming of the said goods is the pressure surface at pressing plate two ends is fixed, and this has the clamping of angle, tapering product to some is to bring certain trouble, and also will be with extremely descending to the fastness of clamping, and the inventor is further improved the said goods for this reason.

Summary of the invention

Technical problem to be solved in the utility model provide a kind of easy to use, can adapt to more changeable mounting condition and higher, the more practical presser device of clamping dynamics.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: it comprises the pressing plate main body block, goes up cushion block, lower cushion block, last cushion block places on the lower cushion block, lower cushion block places on the surface, both sides of vallecular cavity upper opening of pressing plate main body block, last cushion block is that cambered surface cooperates with lower cushion block, and be respectively equipped with the perforation that allows standing screw to pass at the middle part of last cushion block and lower cushion block, it is characterized in that the front end pressure surface of pressing plate main body block and/or rear end pressure surface can rotate front and back respectively on corresponding position from the center.

The front end pressure surface of above-mentioned pressing plate main body block is positioned on the front pressuring plate pin, and the front pressuring plate pin is arranged in the front end groove of pressing plate main body block; The rear end pressure surface of pressing plate main body block is positioned on the rear fender pin, and the rear fender pin is arranged in the rear end groove of pressing plate main body block.

The back side of above-mentioned its front end pressure surface of front pressuring plate pin is circular arc, the circular arc inner chamber is suitable and be connected together movably in the back side of this circular arc and the front end groove, the back side of rear fender pin its rear end pressure surface is circular arc, and the circular arc inner chamber is suitable and be connected together movably in the back side of this circular arc and the rear end groove.

Can also be shaped on the arc pin hole on the circular back of above-mentioned front pressuring plate pin, and this arc pin hole with place the suitable and sleeve of its bottom is equipped with spring in the front end groove latch together, can be shaped on the arc pin hole equally on the circular back of described rear fender pin, and this arc pin hole with place the suitable and sleeve of its bottom is equipped with spring in the groove of rear end latch together.

Can also be connected with adapter sleeve on the above-mentioned pressing plate main body block, adapter sleeve will be gone up cushion block, lower cushion block and pressing plate main body block successively and link into an integrated entity, described adapter sleeve is " Qian " shape, the baseplane is an annulus, the screw hole that allows standing screw to pass is arranged in the middle of the annulus, and the annulus overall diameter is greater than the vallecular cavity width, the adapter sleeve both sides are straight line and extend on the two side of cushion block, and fixed with each other with rivet, and its baseplane annulus button is held on the both sides of pressing plate main body block lower surface vallecular cavity opening.

Compared with prior art, advantage of the present utility model be because of the front end pressure surface that adopts the pressing plate main body block and/or rear end pressure surface respectively on the corresponding position can before and after the structure of rotating, the front end pressure surface of pressing plate main body block is positioned on the front pressuring plate pin, and the front pressuring plate pin is arranged in the front end groove of pressing plate main body block, the rear end pressure surface of pressing plate main body block is positioned on the rear fender pin, and the rear fender pin is arranged in the rear end groove of pressing plate main body block.This structure is when pressing plate main body block clamping workpiece, the front and back pressure surface of pressing plate main body block can be according to the impetus direction of workpiece and the clamping location, is the inclined-plane as workpiece by the position of clamping, then the pressure surface of pressing plate main body block can turn to the inclined-plane and amplexiforms mutually, make the clamping power and the inclined-plane of standing screw form normal pressure, and also being provided with groined type on the pressure surface of front and back two ends increases anti-skidding striped, thereby has avoided the decline of clamping power effectively; Therefore this product has not only possessed whole advantages of original product, but also has fundamentally overcome the shortcoming of original product, make the scope of application of this product, wider than original product, clamping is more firm, more practical.
