Abstract

The invention relates to clamping devices, in particular to a double-direction eccentric clamping device. The double-direction eccentric clamping device comprises a base, an air cylinder, a pressing plate provided with a clamping head and a transmission mechanism. The end, far away from the clamping head, of the pressing plate is provided with an L-shaped flange with the middle portion hinged to the base; a reset spring is arranged between the L-shaped flange and the base; the transmission mechanism comprises a rotary arm, a double-direction eccentric wheel, a connecting rod driven by the air cylinder and a rotating shaft connected with the base in a rotating mode; one end of the rotary arm and the double-direction eccentric wheel are fixedly connected with the upper end of the rotating shaft and the lower end of the rotating shaft respectively; the other end of the rotary arm is hinged to the end, far away from the air cylinder, of the connecting rod; when the double-direction eccentric wheel rotates, the bottom end of the L-shaped flange is pushed. The clamping device can simultaneously clamp two potions of a workpiece, so that the clamped workpiece is more stable.

Description

Bidirectional eccentric clamping device
Technical field
The present invention relates to a kind of clamping device, be specifically related to a kind of bidirectional eccentric clamping device.
Background technology
On lathe, during processing work, conventionally to use fixture that workpiece is fixed, so the effect of jig is very important.And the core of jig is clamping device.
In common clamping device, eccentric clamping device not only has self-locking and power enlarging function, and have the advantages such as simple in structure, anufacturability good, easy to operate, clamping process is rapid, thereby it has obtained application very widely in mechanical manufacturing field.But when existing eccentric clamping device is used, a position that conventionally can only holding workpiece, so it is unstable to add the workpiece being held man-hour.
Summary of the invention
The defect existing for above-mentioned prior art, the object of the present invention is to provide a kind of bidirectional eccentric clamping device, and this clamping device is two positions of holding workpiece simultaneously, so it is more stable to be held workpiece.
For achieving the above object, technical scheme of the present invention is: bidirectional eccentric clamping device, comprise pedestal, cylinder, pressing plate and the transmission mechanism with clamping head, wherein, described pressing plate clamping head far away one end is provided with middle part and is articulated with " L " shape flange on pedestal, between described " L " shape flange and pedestal, be provided with back-moving spring, described transmission mechanism comprises pivoted arm, bidirectional eccentric wheel, the connecting rod of air cylinder driven and the rotating shaft being rotationally connected with pedestal, in one end of described pivoted arm and the rotating shaft of bidirectional eccentric wheel difference, lower end is fixedly connected with, the pivoted arm other end and connecting rod cylinder far away one end is hinged, the bottom that bidirectional eccentric wheel promotes " L " shape flange while rotating.
While adopting technique scheme, workpiece is positioned on workbench, pressing plate pinching end is positioned at workpiece top, and workpiece one side is taken turns near bidirectional eccentric, when bidirectional eccentric wheel rotates, bidirectional eccentric is taken turns the bottom that a side promotes " L " shape flange, pressing plate is rotated around pin joint, and clamping head is exerted pressure to workpiece from top, and bidirectional eccentric wheel opposite side is exerted pressure in side surface of workpiece, workpiece opposite side is supported on workbench, thereby by Workpiece clamping.The present invention takes turns by bidirectional eccentric and pressing plate clamps at two positions of workpiece, and the workpiece being held is more stable.
Further, described rotating shaft and pivoted arm and bidirectional eccentric wheel are threaded, and bidirectional eccentric wheel is easily wearing and tearing in use, and the mode that is threaded is for convenience detach and change.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of bidirectional eccentric clamping device embodiment of the present invention.
The specific embodiment
As shown in Figure 1, a kind of bidirectional eccentric clamping device, comprise pedestal 1, cylinder, pressing plate 5 and the transmission mechanism with clamping head 51, pedestal 1 by bolt wherein, pressing plate 5 clamping head far away 51 one end are provided with middle part and are articulated with " L " shape flange 7 on pedestal 1, " L " shape flange 7 upper ends are connected with pressing plate 5, 1 of " L " shape flange 7 and pedestal are provided with back-moving spring, transmission mechanism comprises pivoted arm 3, bidirectional eccentric wheel 6, the connecting rod 2 of air cylinder driven and the rotating shaft 4 being rotationally connected with pedestal 1, in one end of pivoted arm 3 and the 6 difference rotating shafts 4 of bidirectional eccentric wheel, lower end screw thread is fixedly connected with, pivoted arm 3 other ends and connecting rod 2 cylinder far away one end are hinged, the bottom that bidirectional eccentric wheel 6 promotes " L " shape flange 7 while rotating.
The concrete flow process of using:
Figure 1 shows that clamping head 51 is in clamp position.As Fig. 1, workpiece 9 is positioned on workbench 8, pressing plate 5 pinching ends are positioned at workpiece 9 tops, workpiece 9 one sides are near bidirectional eccentric wheel 6, workpiece 9 opposite sides are supported on workbench 8, when the air admission hole on cylinder right side enters Compressed Gas, the piston rod of cylinder pulls connecting rod 2 to be moved to the left, connecting rod 2 pulls pivoted arm 34 to rotate counterclockwise around the shaft simultaneously, now, eccentric wheel rotates with rotating shaft 4, bidirectional eccentric is taken turns the bottom of side promotion " L " shape flange 7 that 6 eccentric throws are larger, pressing plate 5 is rotated around pin joint, clamping head 51 is exerted pressure from top to workpiece 9, bidirectional eccentric is taken turns the opposite side that 6 eccentric throws are larger and is exerted pressure in workpiece 9 sides, thereby workpiece 9 is clamped.When the air admission hole in cylinder left side enters Compressed Gas, the piston rod of cylinder promotes connecting rod 2 and moves right, connecting rod 2 promotion pivoted arms 34 clockwise rotate around the shaft simultaneously, now, eccentric wheel rotates with rotating shaft 4, and bidirectional eccentric wheel 6 directly extruding workpiece 9 one sides unclamps workpiece 9, and compressed back-moving spring promotes " L " shape flange 7, pressing plate 5 is clockwise rotated, and clamping head 51 unclamps workpiece 9.
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.
