Description
Technical field
The utility model belongs to a kind of clamping device, is specifically related to the rotating cam clamping device.
Background technology
Clamping device is widely used in manufacturing.Be mainly used in clamping and the location of workpiece, so that workpiece obvious displacement does not take place adding man-hour, thereby improve machining accuracy.Clamping device commonly used comprises pedestal, force application rod, jaw, work stage, and force application rod and jaw are hinged, by press down and on draw force application rod, drive pressing down and rising of jaw, thus the clamping of realization workpiece and unclamping.
Though this clamping device can satisfy the clamping demand of workpiece to a certain extent, in actual use, still has the following disadvantages: 1, operation is wasted time and energy.2, can only once clamp a workpiece, efficient is low.
Summary of the invention
The purpose of this utility model is to provide a kind of time saving and energy saving and rotating cam clamping device that efficient is high.
For achieving the above object, the technical solution of the utility model is: a kind of rotating cam clamping device is provided, comprises frame, expansion set, force application rod, jaw, described central rack has through hole; Described expansion set passes through hole and fixed with frame; Described frame upper surface is positioned at the expansion set both sides and is provided with the fixture block that possesses the horizontal free degree; Described fixture block contacts with expansion set; The driven end of described force application rod passes expansion set, and the driven end of described force application rod is provided with cam, and force application rod is provided with vertical keyway and cam riveted joint, also is provided with the stopper slot that links to each other with vertical keyway; The both sides of described force application rod drive end are consolidated with bolt; The drive end of described jaw offers keyhole, and described bolt and keyhole are slidingly connected; Described jaw is hinged on the frame, and the clamping section of described jaw is corresponding with fixture block.
When adopting technique scheme, workpiece is placed between jaw clamping section and the fixture block, rotate force application rod, the cam that drives the force application rod driven end rotates, when cam turn to distal end contact expansion set the time, strut expansion set to both sides, expansion set pushes fixture block, makes an end of fixture block clamping work pieces, and the drive end of force application rod drives the clamping section of jaw by rotating in the middle of two side direction simultaneously, the other end of clamping work pieces, thereby the clamping of realization workpiece.The rotation urging bar makes progress, cam rotates thereupon, when cam goes to proximal part by distal end, the pressure that expansion set loses cam shrinks, the pressure that briquetting loses expansion set unclamps an end of workpiece, and force application rod moves upward simultaneously, drives jaw and opens fully, unclamp the other end of workpiece, thereby realize unclamping of workpiece.Because cam and force application rod be by the riveted joint of vertical keyway, thereby use very little power just can make force application rod drive the cam rotation quick rotation time up and down, thus more time saving and energy saving clamping or unclamp workpiece.Because this rotating cam clamping device can clamp two workpiece simultaneously, efficient is higher.
The drive end of further described force application rod is provided with turning handle.This structure can be convenient the rotation urging bar.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model rotating cam clamping device.
The specific embodiment
Embodiment 1: as shown in Figure 1, the utility model provides the rotating cam clamping device, comprises frame 1, expansion set 12, force application rod 4, left jaw 2 and right jaw 3, and described frame 1 middle part has through hole; Described expansion set 12 passes through hole and fixed with frame 1; Described frame 1 upper surface is positioned at expansion set 12 both sides and is provided with left fixture block 5 and the right fixture block 6 that possesses the horizontal free degree; Described left fixture block 5 contacts with expansion set 12 with right fixture block 6; The driven end of described force application rod 4 passes expansion set, and the driven end of described force application rod 4 is provided with cam 7, and 4 are provided with vertical keyway 8 and cam 7 riveted joints on the force application rod, also are provided with the stopper slot that links to each other with vertical keyway 8; The both sides of described force application rod 4 drive ends are consolidated with bolt; The drive end of described jaw 2 and jaw 3 offers left button hole 9 and right button hole 10, and described bolt and left button hole 9 and right button hole 10 are slidingly connected; Described left jaw 2 and right jaw 3 are hinged on the frame, and the clamping section of described left jaw 2 and right jaw 3 is corresponding with left fixture block 5 and right fixture block 6.
During use, workpiece is placed between the clamping section and left fixture block 5 and right fixture block 6 of left jaw 2 and right jaw 3, rotate force application rod 4, cam 7 cams that drive force application rod 4 driven ends rotate, when cam 7 turn to distal end contact expansion set 12 time, extruding expansion set 12, expansion set 12 extruding fixture block 5 and fixture blocks 6, make an end of fixture block 5 and fixture block 6 clamping work pieces, the drive end of force application rod 4 drives the clamping section of jaw 2 and jaw 3 by rotating in the middle of two side direction simultaneously, the other end of clamping work pieces, thereby the clamping of realization workpiece.Rotation urging bar 4 makes progress, because cam 7 is riveted by vertical keyway 8 with force application rod 4, using very little power just can make force application rod drive cam 7 about in the of 4 quick rotation the time rotates, thereby can use very little power easily to allow cam 7 contact with expansion set 12 from distal end fast turns to proximal part and contacts with expansion set 12, stopper slot on the force application rod 4 can prevent that cam 7 and force application rod 4 from endwisely slipping, the pressure that expansion set 12 loses cam 7 shrinks, the pressure that briquetting 5 and briquetting 6 lose expansion set 12 unclamps an end of workpiece, force application rod 4 moves upward simultaneously, driving jaw 2 and jaw 3 opens fully, unclamp the other end of workpiece, thereby realize unclamping of workpiece.And this rotating cam clamping device can clamp two workpiece simultaneously, and efficient is higher.
The difference of the rotating cam clamping device of 2: the second kinds of embodiments of embodiment and the rotating cam clamping device of first kind of embodiment only is that the drive end of described force application rod 4 is provided with turning handle 11.This structure can be convenient rotation urging bar 4.
Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
