The first clamping driving device 420 is an oil cylinder, and may be an air cylinder, an electric push rod, or the like in other embodiments.
Through the arrangement, the four sides of the workpiece are clamped, and the workpiece is clamped and has high positioning precision.
The working principle of the embodiment is as follows: the upper positioning block 411, the lower positioning block 413 and the left positioning block 412 are arranged on the rack 100, the right positioning block 414 is driven by a clamping mechanism, when the output end of the first clamping driving device 420 moves upwards, the first clamping driving device 420 rotates downwards, meanwhile, the first clamping connecting rod 421 is driven to rotate upwards around the hinge point between the middle part of the first clamping driving device and the rack 100, the first clamping connecting rod 421 rotates upwards to drive the clamping arm 423 to rotate around the hinge point between the middle part of the clamping arm 423 and the first clamping hinge seat 424 through the second clamping connecting rod 422, the right positioning block 414 rotates leftwards to compress a clamping space, and therefore workpiece clamping is achieved. The upper part, the lower part, the left part and the right part of the workpiece are correspondingly provided with positioning parts, and the clamping precision of the workpiece is high.
In some embodiments, the positioning and supporting mechanism further includes a height-adjusting driving motor 430 fixedly connected to the frame 100, a height-adjusting screw 431 fixedly connected to an output end of the height-adjusting driving motor 430, a height-adjusting sleeve 432 in threaded connection with the height-adjusting screw 431, and an extending arm 433 hinged to the height-adjusting sleeve 432, a left portion of the positioning swing arm 410 is hinged to a right portion of the height-adjusting sleeve 432, a lower portion of the positioning swing arm 410 is hinged to the frame 100 through a positioning connecting rod 435, the positioning and supporting mechanism further includes a height-adjusting support fixedly connected to the frame 100, a height-adjusting slide hole is formed in the height-adjusting support, a height-adjusting slider is arranged on a front side of the height-adjusting sleeve 432, and the height-adjusting slider is slidably connected to the height-adjusting slide hole. Therefore, when the heightening motor drives the heightening screw 431 to rotate to drive the heightening slider on the heightening sleeve 432 to slide upwards along the heightening slide hole, the upper positioning block 411 and the left positioning block 412 are driven to swing towards one side of the clamping space through the clamping arm 423 to clamp a workpiece; on the contrary, when the workpiece is loosened, the height adjusting sleeve 432 slides downwards when the height adjusting driving motor 430 drives the height adjusting screw 431, the upper positioning block 411 and the left positioning block 412 are driven to swing to the side away from the clamping space through the clamping arm 423, and the upper part of the clamping space is opened at the moment, so that the workpiece can be lifted upwards by a crown block, and the workpiece is more convenient to transfer.

In some embodiments, two sets of positioning and supporting mechanisms share one height-adjusting driving motor 430, height-adjusting screw 431, height-adjusting sleeve 432 and extension arm 433, so as to save the number of parts and reduce the cost of the positioning and clamping device. Further, the clamping arms 423 and the positioning swing arms 410 of the two sets of positioning support mechanisms are symmetrically arranged about the height-adjusting support. Therefore, the height-adjusting sleeve 432 can synchronously drive the clamping arms 423 on the two sides to rotate, and simultaneously drive the positioning swing arm 410 to clamp the workpiece.
In some embodiments, a limit screw hole is formed at the top of the height-adjusting support, a height-limiting screw 434 is screwed into the limit screw hole, and the bottom end of the height-limiting screw 434 extends to the height-adjusting sleeve 432. The arrangement of the height limit screw 434 limits the swing stroke of the positioning swing arm 410 and prevents deformation caused by overpressure of the workpiece.
In some embodiments, the frame 100 is further provided with a clamping limiting block 425, the clamping limiting block 425 is located above the first clamping connecting rod 421, and the position of the clamping limiting block 425 corresponds to the position of the first clamping connecting rod 421. When the clamping mechanism is located at the tail end of the stroke, the clamping mechanism is blocked by the clamping limiting block 425, and the workpiece is not easy to deform obviously due to the fact that the workpiece is over-pressed.
While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments, but is capable of various changes and modifications without departing from the spirit of the invention.
