Description
Technical field
The invention belongs to a kind of clamping device, be 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 occur 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, the pressing down and rise of driving jaw, thus realize the clamping of workpiece and unclamp.
Although 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 object of the invention 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, technical scheme of the present invention 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 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 is connected with vertical keyway; The both sides of described force application rod drive end are consolidated with nut; The drive end of described jaw offers keyhole, and described nut and keyhole are slidably connected; Described jaw is hinged on 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 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, thus realize the clamping of 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, thus band moving cam rotation when using very little power just can make force application rod up and down quick rotation, 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
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of rotating cam clamping device of the present invention.
The specific embodiment
Embodiment 1: as shown in Figure 1, the invention provides the rotating cam clamping device, comprise frame 1, expansion set 12, force application rod 4, left jaw 2 and right jaw 3, 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 on force application rod, 4 are provided with vertical keyway 8 and cam 7 riveted joints, also are provided with the stopper slot that is connected with vertical keyway 8; The both sides of described force application rod 4 drive ends are consolidated with nut; The drive end of described jaw 2 and jaw 3 offers left button hole 9 and right button hole 10, and described nut and left button hole 9 and right button hole 10 are slidably connected; Described left jaw 2 and right jaw 3 are hinged on 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, thus realize the clamping of workpiece.rotation urging bar 4 makes progress, because cam 7 is riveted by vertical keyway 8 with force application rod 4, use very little power just can make force application rod Shang Xia 4 quick rotation time band moving cam 7 rotate, thereby can use very little power easily to allow fast cam 7 contact with expansion set 12 from distal end to turn to proximal part contacts with expansion set 12, stopper slot on 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.
Embodiment 2: the difference of the rotating cam clamping device of the second embodiment and the rotating cam clamping device of the first 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 is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from 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.
