Description
Technical Field
The utility model relates to a clamping mechanism, especially a scissors formula hydraulic clamping mechanism.
Background
When a workpiece is machined, the workpiece needs to be first positioned and clamped by a tool holder, and various types of tools have been proposed in the field of machining in order to perform clamping operations on various types of workpieces. For some workpieces with small volume, if clamping operation is required to be carried out on the workpieces, the clamp is required to have the characteristics of flexible and accurate action. Meanwhile, under some working conditions, the action space of the clamp can be greatly limited, and the traditional clamp is generally large in size and is not suitable for the situation. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.
Disclosure of Invention
The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed, occupation space is little, the nimble accurate scissors formula hydraulic clamping mechanism of action.
The technical solution of the utility model is that: a scissors formula hydraulic clamping mechanism which characterized in that: the clamping mechanism comprises a box body 1, a hydraulic cavity 2 and shaft holes communicated with the hydraulic cavity 2 are formed in the box body 1, a piston rod 3 is arranged in the hydraulic cavity 2, two liquid inlet and outlet pipelines 4 communicated with the hydraulic cavity 2 are further arranged on the box body 1, an upper cover 5 is arranged on the box body 1 above the hydraulic cavity 2, the top end of the piston rod 3 is movably connected in a through hole formed in the center of the upper cover 5, a dust ring 6 matched with the piston rod 3 is further arranged on the top end face of the upper cover 5, a clamping jaw support 7 is fixedly connected on the bottom end face of the box body 1, two clamping jaw bodies 8 are symmetrically and rotatably supported on the clamping jaw support 7, a connecting chute 9 is formed in the bottom of the piston rod 3, the two clamping jaw bodies 8 are both connected with the connecting chute 9 through a circular end 12, and pressing blocks 10 are both in threaded connection with the bottom ends of the two clamping jaw bodies 8, and an adjusting pad 11 is padded between the pressing block 10 and the clamping jaw body 8.
Compared with the prior art, the utility model, have following advantage:
the shear type hydraulic clamping mechanism with the structure is simple in structure, ingenious in design and reasonable in layout. Aiming at the problems of the traditional clamping mechanism in the using process, a special clamp structure is designed. The hydraulic clamping device drives a piston rod to move linearly by utilizing a hydraulic principle, and drives two symmetrically arranged clamping jaw bodies to swing simultaneously by utilizing a lever principle, so that the clamping operation of a workpiece is realized. The clamping device has small action amplitude, but the action is accurate and smooth, and the clamping device does not need to occupy too much space, and is particularly suitable for clamping workpieces in a narrow space environment. And the manufacturing process is simple, the manufacturing cost is low, so that the novel LED lamp has multiple advantages, is particularly suitable for popularization and application in the field, and has a very wide market prospect.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Fig. 2 is a partially enlarged view of a portion a in fig. 1.
Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 and 2: a scissor type hydraulic clamping mechanism comprises a box body 1, a hydraulic cavity 2 and shaft holes communicated with the hydraulic cavity 2 are arranged on the box body 1, a piston rod 3 is arranged in the hydraulic cavity 2, two liquid inlet and outlet pipelines 4 communicated with the hydraulic cavity 2 are also arranged on the box body 1, an upper cover 5 is arranged on the box body 1 above the hydraulic cavity 2, the top end of the piston rod 3 is movably connected in a through hole arranged at the center of the upper cover 5, a dust ring 6 matched with the piston rod 3 is also arranged on the top end surface of the upper cover 5, a clamping jaw support 7 is fixedly connected on the bottom end surface of the box body 1, two clamping jaw bodies 8 are symmetrically and rotatably supported on the clamping jaw support 7, a connecting chute 9 is arranged at the bottom of the piston rod 3, the two clamping jaw bodies 8 are both connected with the connecting chute 9 through a circular end 12, and pressing blocks 10 are both in threaded connection with the bottom ends of the two clamping jaw bodies 8, and an adjusting pad 11 is padded between the pressing block 10 and the clamping jaw body 8.
The shear type hydraulic clamping mechanism with the structure mode has the following working process: when a workpiece needs to be clamped and positioned, firstly, hydraulic oil is filled into the hydraulic cavity 2 through the liquid inlet and outlet pipeline 4, the piston rod 3 is pushed to move by the hydraulic oil, as shown in fig. 1, when the piston rod 3 descends, the circular end head 12 connected with the connecting chute 9 at the bottom end of the piston rod 3 also swings downwards, and then the two clamping jaw bodies 8 are driven to swing, at the moment, the two pressing blocks 10 are far away from each other, and the clamping jaws are loosened;
when the piston rod 3 moves upwards, the round end 12 connected with the connecting chute 9 at the bottom end of the piston rod 3 also swings upwards to drive the two clamping jaw bodies 8 to swing, at the moment, the two pressing blocks 10 are close to each other, and the pressing blocks between the two pressing blocks 10 are clamped and fixed by the clamping jaw;
when the relative position between the pressing block 10 and the clamping jaw body 8 needs to be adjusted, the adjustment can be realized by replacing the adjusting pads 11 with different thicknesses.
