Abstract
The invention discloses a fixture convenient for punching, which comprises an upper cover, a lower cover, a body, short screws and long screws. Both the upper cover and the lower cover are provided with counter bores. The body is provided with an opening in the center, and the opening is the same as a workpiece in shape. Both the top and the bottom of the body are provided with threaded holes corresponding to the counter bores on the upper cover and the lower cover. The upper cover is provided with two through holes corresponding to positions, to be punched, on the workpiece. The upper cover is fixed to the body through the short screws on the counter bores of the upper cover. The lower cover is provided with a projection in the center, which is the same as the workpiece in shape. The projection is fixedly connected with the lower cover, and both sides of the projection are graduated. The projection is inserted into the opening. The lower cover is fixed to the body through the long screws on the counter bores of the lower cover. By means of the fixture convenient for punching, machining precision can be well guaranteed, and a plurality of workpieces can be machined simultaneously. The fixture is convenient in operation and highly practical.
Description
Technical field
The present invention relates to a kind of anchor clamps, especially a kind of anchor clamps of convenient punching.
Background technology
Because the development of production technology, mechanical structures also is varied, and the machine components of the inside structure especially are numerous, and machine components are single products that can not be split of forming machinery and machine, and is the elementary cell of machinery.There is a kind of thin plate (as shown in Figure 3) of half arc to process now, mainly need stamps the hole at the two ends of workpiece.Such workpiece belongs to irregular workpiece, and the position of upper surface hole also is irregular, and it is very inconvenient to be fixed up.Existing method generally all is to adopt pressing plate and clamp nut to be fixed to workpiece on the drilling machine; And then process, can punch though do like this, depend the words of clamp nut alone; Precision can not guarantee fully; And the get up trouble of comparison of processing, once also being merely able to process a workpiece, production efficiency is low.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of anchor clamps of convenient punching, solved enough bad assurances of precision in the processing work hole, the problem that once can only process a workpiece.
Technical solution of the present invention is achieved in that a kind of anchor clamps of convenient punching, comprises upper cover body, lower cover, main body, short screw and long spiro nail; All have counterbore on said upper cover body and the lower cover; Offer an opening in the said main body in the heart, and the shape of opening is identical with the shape of workpiece; Said main body upper and lower surface is equipped with screwed hole, and corresponding with the counterbore of upper cover body and lower cover respectively; Said upper cover body has two through holes, and the position of through hole is corresponding with the position that workpiece need punch; Said upper cover body is fixed through short screw on the counterbore and main body; The center position of said lower cover is provided with the projection identical with the workpiece shape; Said projection is fixedly connected with lower cover, and the projection both sides are provided with scale; Said projection is inserted in the opening; Said lower cover is fixed through long spiro nail on the counterbore and main body.
Preferably, the counterbore quantity of said upper cover body and lower cover is four.
Preferably, said upper cover body and lower cover are cuboid.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The anchor clamps of a kind of convenient punching of the present invention program only need be put into workpiece in the opening of main body, fix through upper cover body and lower cover then; To drilling machine, just can process clamps workpiece; But also can once process the polylith workpiece simultaneously, so not only well guaranteed the machining accuracy of workpiece, and simple to operate; Practical, improved production efficiency.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the overall structure exploded view of the anchor clamps of convenient punching of the present invention;
Accompanying drawing 2 is the structural representation of the lower cover of the convenient anchor clamps that punch of the present invention;
Accompanying drawing 3 is the structural representation of the workpiece of the convenient anchor clamps that punch of the present invention;
Wherein: 1, upper cover body; 2, lower cover; 3, main body; 4, projection; 5, long spiro nail; 6, short screw; 7, through hole; 8, opening; 9, screwed hole; 10, scale; 11, counterbore; 12, workpiece.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1 is the anchor clamps of a kind of convenient punching of the present invention, comprises upper cover body 1, lower cover 2, main body 3, short screw 6 and long spiro nail 5; All have counterbore 11 on said upper cover body 1 and the lower cover 2; Offer one in the said main body 3 in the heart and open 8 mouthfuls, and the shape of opening 8 is identical with 12 shapes of workpiece; Said main body 3 upper and lower surfaces are equipped with screwed hole 9, and corresponding with the counterbore 11 of upper cover body 1 and lower cover 2 respectively; Said upper cover body 1 has two through holes 7, and the position of through hole 7 needs the position of punching corresponding with workpiece 12; Said upper cover body 1 is fixed through short screw on the counterbore 11 6 and main body 3; The center position of said lower cover 2 is provided with the projection 4 identical with the workpiece shape; Said projection 4 is fixedly connected with lower cover 2, and projection 4 both sides are provided with scale 10; Said projection 4 is inserted in the opening 8; Said lower cover 2 is fixed through long spiro nail on the counterbore 11 5 and main body 3; Counterbore 11 quantity of said upper cover body 1 and lower cover 2 are four; Said 1 upper cover body and lower cover 2 are cuboid.
When carrying out practical operation; At first be fixed to upper cover body on the main body through short screw; Put into workpiece in the opening of main body then, then be inserted into projection in the opening, be fixed to lower cover on the main body through long spiro nail; Just can punch through two through holes on the upper cover body at last, can well guarantee the precision of workpiece like this workpiece.
In process; Can also according to the production requirement of reality adjust once can processing work quantity, when processing work, regulate the quantity of the processing work that opening once can hold through the scale on the projection; And then fix through long spiro nail; When guaranteeing precision, improved production efficiency like this, and simple to operate, be applicable to large batch of production.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
