Abstract
The invention discloses machine tool parts for assembly and particularly relates to a balance type pressing plate. The balance type pressing plate comprises a frame and an air cylinder, wherein the air cylinder is arranged on the frame, the output shaft of the air cylinder is vertically upward, the end portion of the output shaft of the air cylinder is provided with a gear, the gear is arranged on the pin shaft of the output shaft of the air cylinder, both sides of the gear are symmetrically matched with racks which are in sliding fit with the frame, and the upper end of each rack is provided with a horizontal pressing plate unit. The balance type pressing plate is simple in structure and can clamp two workpieces simultaneously.
Description
Technical field
The present invention relates to a kind of work holder, be specifically related to a kind of balanced type pressing plate.
Background technology
In machinery assembling process, conventionally after needing first Workpiece clamping device to be fixed, assemble again, reduce the difficulty of assembling and improve assembly quality, because the positional precision of workpiece is guaranteed by clamping device, can not be subject to the impact of workman's technical merit, so Workpiece Machining Accuracy is high and stable, guaranteed the quality of product; But universal clamping device complex structure, complex operation, maintenance maintenance cost is high.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of simple to operate, service efficiency is high, can clamp the balanced type pressing plate of two workpiece simultaneously.
In order to solve the problems of the technologies described above, the invention provides a kind of balanced type pressing plate, comprise that frame and cylinder, described cylinder are fixedly installed in frame, the output shaft of cylinder straight up, the output shaft end of described cylinder is provided with gear, and described gear is arranged on the bearing pin on the output shaft of cylinder, and described gear bilateral symmetry is combined with tooth bar, described two tooth bars and frame are slidably matched, and described two tooth bar upper ends are respectively arranged with the pressing plate of level.
Adopt the balanced type pressing plate tool of technique scheme to have the following advantages: two workpiece are placed on pressing plate below, cylinder output shaft is retracted, and gear and both sides tooth bar clamping due to cylinder end, make bar teeth directional lower slider, pressing plate moves down, and one of them pressing plate is workpiece pressing first; Cylinder output shaft continue to be retracted, and because the tooth bar of workpiece pressing wherein can not move, another rack and pinion coordinates, and makes this tooth bar continue to move down, until the pressing plate workpiece pressing on this tooth bar.By said process, realize and compress two workpiece simultaneously.
Further, the lower surface of described two pressing plates is provided with cushion course.The surface of protection workpiece.
Further, described two pressing plates are rectangular slab, and with the be connected tooth bar structure that is formed in one.Improve whole intensity.
Accompanying drawing explanation
Fig. 1 is the structural representation of balanced type pressing plate of the present invention.
The specific embodiment
Reference numeral in Figure of description comprises: cylinder 1, gear 2, tooth bar 3, pressing plate 4.
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
As shown in Figure 1, a kind of balanced type pressing plate, comprise that frame and cylinder 1, described cylinder 1 are fixedly installed in frame, the output shaft of cylinder 1 straight up, the output shaft end of described cylinder 1 is provided with gear 2, and described gear 2 is arranged on the bearing pin on the output shaft of cylinder 1, and described gear 2 bilateral symmetry are combined with tooth bar 3, described two tooth bars 3 are slidably matched with frame, and described two tooth bar 3 upper ends are respectively arranged with the pressing plate 4 of level.The lower surface of described two pressing plates 4 is provided with cushion course.Described two pressing plates 4 are rectangular slab, and be connected tooth bar 3 structure that is formed in one.
Two workpiece are placed on pressing plate 4 belows, and cylinder 1 output shaft is retracted, and gear 2 and both sides tooth bar 3 clampings due to cylinder 1 end, make bar teeth directional lower slider, and pressing plate 4 moves down, and one of them pressing plate 4 is workpiece pressing first; Cylinder 1 output shaft continue to be retracted, and because the tooth bar 3 of workpiece pressing wherein can not move, another tooth bar 3 coordinates with gear 2, makes this tooth bar 3 continue to move down, until pressing plate 4 workpiece pressings on this tooth bar 3.By said process, realize and compress two workpiece simultaneously.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
