Fig. 2 is a schematic structural diagram of a second working state of the embodiment of the present invention.
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 small-space rotary type hinge clamping mechanism comprises a support 1, an oil cylinder 2 is fixedly arranged at the bottom of the support 1, the end part of a working shaft of the oil cylinder 2 is hinged with a left swing rod 4 and a right swing rod 5 through a first pin shaft 3, a fixed column 6 is further arranged on the support 1, the top end of the fixed column 6 is hinged with the bottom end of a first swing rod 8 through a second pin shaft 7, the top end of the first swing rod 8 is hinged with a clamping jaw body 10 through a third pin shaft 9, the third pin shaft 9 is positioned in the middle of the clamping jaw body 10, an arc-shaped clamping part 11 is arranged at one end of the clamping jaw body 10, a positioning part 12 which is also arc-shaped is arranged at the other end far away from the clamping part 11, the left swing rod 4 is connected with the clamping jaw body 10 through a second swing rod 13, and the left swing rod 4 is hinged with the second swing rod 13 through a fourth pin shaft 14, the second swing rod 13 is hinged to the clamping jaw body 10 through a fifth pin shaft 15, meanwhile, the fifth pin shaft 15 is located at the positioning portion 12, and the right swing rod 5 is hinged to the middle of the first swing rod 8 through a sixth pin shaft 16.
The utility model discloses little space rotation type hinge clamping mechanism's working process as follows: in the initial state, the clamping mechanism is in the state shown in figure 1, when a workpiece needs to be clamped, the oil cylinder 2 is started, the working end of the oil cylinder 2 is ejected upwards, the left swing rod 4 and the right swing rod 5 are pushed to act at the same time, when the working end of the oil cylinder 2 is in the completely extended state, the axes of the left swing rod 4 and the right swing rod 5 are collinear,
in the process, the right swing rod 5 can push the first swing rod 8 to swing clockwise by taking the second pin shaft 7 as a swing point, and the top end of the first swing rod 8 can drive the whole clamping jaw body 10 to translate spatially;
the left swing rod 4 pushes the second swing rod 13 to move upwards from the lower part, and one end of the second swing rod 13 is hinged with the clamping jaw body 10 through the fifth pin shaft 15, so that in the process of clockwise translation of the whole clamping jaw body 10, the fifth pin shaft 15 applies an upward inclined force to the clamping jaw body 10, and the force drives the clamping jaw body 10 to swing by taking the third pin shaft 9 as an axis;
the translational motion enables the clamping part 11 on the clamping jaw body 10 to move to the position above the clamped position of the workpiece, the swinging motion enables the clamping part 11 to swing downwards and press the clamped position of the workpiece, and the positioning part 12 on the clamping jaw body 10 is just pressed at the end of the working shaft of the oil cylinder 2 to realize the clamping motion; after the operation is completed, the clamping mechanism is in the state shown in fig. 2.
When the freedom degree of a workpiece needs to be recovered, the working end of the oil cylinder 2 is recovered, the left swing rod 4 and the right swing rod 5 are pulled to move downwards, the left swing rod 4 moves downwards, the second swing rod 13 is pulled to move, under the action of a lever principle, the clamping jaw body 10 swings with the third pin shaft 9 as a shaft, the clamping part 11 swings anticlockwise, and the constraint on the workpiece is released;
meanwhile, the right swing rod 5 pulls the first swing rod 8 to swing counterclockwise by taking the second pin shaft 7 as a swing point, the top end of the first swing rod 8 drives the whole clamping jaw body 10 to translate in space, and finally the state is returned to the state shown in fig. 1.
