The working process of the invention is as follows: in use, the quick mechanical transmission four-jaw synchronous clamp capable of adapting to non-flat workpieces is usually fixedly connected to a machine tool workbench, and can be fixedly connected with the machine tool workbench by bolts through the assembly holes 17. The driving rod 13 is twisted to enable the claw heads 3a of the four clamping claws 3 to be outwards opened to vacate the installation space of the workpiece 24, then the workpiece 24 is placed on the upper surface of the base 1, the two sides of the workpiece 24 are opposite to the clamping claws 3 on the base 1, finally an operator is sleeved on the driving head 15 by using a wrench to reversely twist the driving rod 13, the rotation of the driving rod 13 enables the two pushing plates 10 to synchronously move away, when the pushing plates 10 move, the connecting rod 8 is pushed to move towards the movable groove 6, the connecting rod 8 pushes the driving arm 5 at the lower end of the clamping claw 3 to outwards swing, and meanwhile the claw heads 3a inwards swing to be in compression joint with the upper surface of the workpiece 24, as shown in fig. 7. The following description exemplifies four special cases depending on the surface of the workpiece 24.
Case one: when the upper surface of the workpiece 24 is flat, the driving rod 13 is screwed to enable the four claw heads 3a to be synchronously pressed on the upper surface of the workpiece 24.
And a second case: when the upper surface of the workpiece 24 is thick on one side and thin on the other side, the operator rotates the driving rod 13 to drive the two pushing plates 10 to move away from each other, the two pushing plates 10 synchronously drive the four claw heads 3a to swing inwards, the two claw heads 3a positioned on the thicker side of the workpiece 24 are firstly pressed against the upper surface of the workpiece 24, the claw heads 3a positioned on the other side are still in a separated state with the workpiece, at the moment, the pushing plate 10 connected with the two clamping jaws 3 pressed against the workpiece 24 is kept in a static state under the reaction force of the workpiece 24, and the driving rod 13 is continuously rotated, the driving rod 13 is driven by the pushing plate 10 in the static state to move towards the thinner side of the workpiece 24 along the axial direction, and meanwhile, the pushing plate 10 still in the active state is rapidly moved away from the pushing plate 10 in the static state under the dual action of the rotation and the axial movement of the driving rod 13, so that the claw heads 3a of the two claw heads 3 positioned on the thinner side of the workpiece 24 are driven to rapidly and internally clamp the clamping jaws 24.
And a third case: when there is a difference in thickness between the positions of the same side of the workpiece 24 corresponding to the two clamping jaws 3, the working process of the clamp is complex, and taking fig. 7 as an example, assuming that the left end of the workpiece 24 is thicker and the right end is thinner in fig. 7, in the process of clamping the workpiece 24, the two pushing plates 10 move outwards synchronously, the two clamping jaws 3 on the same side of the workpiece 24 swing inwards synchronously, the jaw 3a of the clamping jaw 3 close to the left end of the workpiece 24 is pressed onto the workpiece 24, and the jaw 3a close to the right end of the workpiece 24 is still in a separated state from the workpiece 24. At this time, the clamping jaw 3 near the left end of the workpiece 24 is kept stationary by the reaction force of the workpiece 24, but the connecting rod 8 connected with the lower end of the clamping jaw is still capable of swinging, in the process of further rotating the driving rod 13, the pushing plate 10 continues to move outwards along the original moving direction, the connecting rod 8 at the lower end of the clamping jaw 3 which is already pressed against the workpiece 24 swings downwards to adapt to the movement of the pushing plate 10, the left end of the pushing plate 10 is driven to swing downwards, the pushing plate 10 swings, the third pin 11 drives one end of the connecting rod 8 to twist, the right end of the pushing plate 10 swings upwards, and the connecting rod 8 at the right end of the pushing plate 10 is driven to continuously push the clamping jaw 3 connected with the pushing plate outwards along with the swinging and moving of the pushing plate 10 until the clamping jaw is pressed against the upper surface of the workpiece 24, so that effective pressing and positioning of the workpiece 24 are realized.
Case four: when the thicknesses of the positions of the workpiece 24 corresponding to the four jaw heads 3a of the clamp are different, the working processes of the clamp are the combination of the two working processes of the second case and the third case.
The swing of the push plate 10 drives the third pin 11 to slightly displace in the horizontal direction, the displacement is small, and the fit clearance between the third pin 11 and the assembly hole 17 is utilized for compensation.
Therefore, the clamp disclosed by the invention can automatically adjust the compression joint heights of the four clamping jaws 3, so that the four clamping jaws can reliably compress the uneven workpiece.
The above embodiments are merely illustrative of the principles and effects of the present invention, and some of the applied embodiments, and are not intended to limit the invention; it should be noted that modifications and improvements can be made by those skilled in the art without departing from the inventive concept, and these are all within the scope of the present invention.
