Abstract
The invention relates to a clamping device, in particular to a double-acting hinge clamping device. The double-acting hinge clamping device comprises a base, pressing plates provided with clamping heads, an air cylinder arranged on the base and a transmission mechanism. The two opposite pressing plates are arranged in the vertical direction and the middle portions of the pressing plates are hinged to the base; the transmission mechanism comprises two hinge arms and a connecting piece driven by a piston rod of the air cylinder; one end of each hinge arm is hinged to the connecting piece and the other end of each hinge arm is connected with the end, far away from the clamping head, of the corresponding clamping plate; a bearing block is further arranged on the base. After the double-acting hinge clamping device is used for clamping a workpiece, a plurality of faces of the workpiece are machined and the machining efficiency is improved.
Description
Technical field
The present invention relates to a kind of clamping device, be specifically related to a kind of double acting hinge clamping device.
Background technology
On lathe, during processing work, all Workpiece clamping must be prevented to workpiece is subject to the effect of the external force such as cutting force and moves in process, clamping device is exactly on lathe, to be used for the device of clamping work pieces.Clamping device generally can sub-power source and running part, and power source is for generation of clamping force, and that power source can come from is pneumatic, hydraulic pressure, manpower etc.Running part is clamping force by power-conversion, realizes and clamps action and clamp effect.
Hinge clamping mechanism is to use aborning more a kind of clamp mechanism, and it is simple in structure, and force increasing ratio is large, therefore, take in the occasion that hydraulic pressure or air pressure is power, and most hinge clamping devices that adopt.Existing hinge clamping device is normally positioned over workpiece on horizontal table and clamps, then processing, and the shortcoming of this clamping device is: after stepping up, can only process workpiece face, so working (machining) efficiency is low.
Summary of the invention
The defect existing for above-mentioned prior art, the object of the present invention is to provide a kind of double acting hinge clamping device, after this clamping device clamping work pieces, can process at a plurality of faces of workpiece, has improved working (machining) efficiency.
For achieving the above object, technical scheme of the present invention is: double acting hinge clamping device, comprise base, there is the pressing plate of clamping head, the cylinder that is arranged at base and transmission mechanism, wherein, at vertical direction, arrange two relatively and middle part is articulated with the pressing plate on base; Described transmission mechanism comprises two hinge arms and the connector being driven by cylinder piston rod; One end of two hinge arms is simultaneously hinged with connector, and the other end is hinged with clamping head far away one end of two pressing plates respectively; On described base, be also provided with rest pad.
While adopting technique scheme, workpiece is positioned between the clamping head of two pressing plates, control cylinder air inlet, connector promotes hinge arms pressing plate hinged end is outwards strutted, the clamping head of pressing plate around pin joint rotate and by Workpiece clamping on rest pad.After clamping work pieces of the present invention, can process three of workpiece surfaces, so improved working (machining) efficiency.
Further, nearly connector one side of described rest pad is provided with the spacer pin that can regulate length, and when two hinge arms are more tending towards straight line, clamping head can add the workpiece of holding reduced size, spacer pin can limit the displacement of connector, so can regulate according to workpiece size the length of spacer pin.
Further, described connector takes the shape of the letter U, and two hinge arms one end are positioned at the middle part of connector U-shaped, and hinge arms hinged end both sides are stressed evenly like this, and connector is more stable when push-and-pull articulated jib.
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 double acting hinge clamping device embodiment of the present invention.
The specific embodiment
As shown in Figure 1, a kind of double acting hinge clamping device, comprise base 1, have clamping head 51 pressing plate 5, be arranged at cylinder 2 and the transmission mechanism of base 1, wherein, at vertical direction, arrange two relatively and middle part is articulated with the pressing plate 5 on base 1; Described transmission mechanism comprises two hinge arms 4 and the connector 3 being driven by cylinder 2 piston rods, and in the present embodiment, connector 3 takes the shape of the letter U, and the hinged end of two hinge arms 4 is positioned in the middle of the U-shaped of connector 3; One end of two hinge arms 4 is simultaneously hinged with connector 3, and the other end is hinged with clamping head far away 51 one end of two pressing plates 5 respectively; On described base 1, be also provided with rest pad 6, nearly connector 3 one sides of rest pad 6 are provided with the spacer pin 7 being threaded with rest pad 6.
Specific works flow process:
As shown in Figure 1, workpiece 8 is positioned between the clamping head 51 of two pressing plates 5, from cylinder 2 left side air admission holes, enter Compressed Gas, Compressed Gas promotes piston and piston rod moves right, and piston rod promotes connector 3 and moves to right, now, two hinge arms 4 outwards strut, and pressing plate 5 clockwise rotates around pin joint, thereby clamping head 51 is clamped in workpiece 8 on rest pad 6, after clamping work pieces 8, can process three of workpiece 8 surfaces; From cylinder 2 right side air admission holes, enter Compressed Gas, Compressed Gas promotes piston and piston rod is moved to the left, and piston rod pulls connector 3 to move to left, now, two hinge arms 4 are inwardly drawn the hinged end of two pressing plates 5, and pressing plate 5 rotates counterclockwise around pin joint, and clamping head 51 unclamps workpiece 8.
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.
