[0077] It should be noted that the positioning and clamping component 1 is preferably a positioning and clamping component; the first fastener 3 is preferably a countersunk bolt; the workpiece mentioned in the present invention is preferably a pipe; the first clamping component 11 Preferably, it is located on the left side of the armor device provided by the present invention; the second clamping member 12 is preferably located on the right side of the armor device provided by the present invention; the second fastener 13 is preferably a locking bolt The first mounting hole 14 of the first fastener is preferably a bolt hole; the second groove 15 is preferably a U-shaped groove; the other end of the first protruding end is a hinged female connector, preferably Is an embedded hinged female connector; the other end of the second protruding end is a hinged male connector, preferably an embedded hinged male connector; one end of the first clamping member 11 is connected to the first protruding end A matching hinged male connector, preferably an embedded hinged male connector; one end of the second clamping member 12 is a hinged female connector matching the second protruding end, preferably an embedded hinged connector Female head; the first 6 is preferably a diamond-shaped pin; the through hole 16 is preferably a hinge hole; the first pin mounting hole 9 is preferably a diamond-shaped pin bolt hole; the zero-point positioning pin mounting hole 8 is preferably Zero-point positioning pin bolt hole; the other end of the first clamping member 11 is preferably a fastening pressure plate; the above-mentioned are preferred examples of the present invention, and should not constitute a limitation to the present invention.
[0078] The present invention is specifically a clamping and positioning device that is easy to disassemble and assemble, which is preferably applied to disassemble and disassemble tubular workpieces; it solves the problem of processing the execution end after repeated clamping, that is, the positioning problem between the manipulator and the tubular workpiece.
[0079] The working principle of the present invention will be further explained below:
[0080] The invention installs the pipe fitting, that is, the tubular workpiece, on the workpiece clamping part 2 of the clamping and positioning device provided by the invention, and tightens the locking bolts so that the clamping, positioning device and the pipe fitting become a fixed workpiece tooling assembly . When the clamping and positioning device is needed in the process, the zero-point positioning pin 5 on the tooling and the zero-point positioning female end of the processing execution end (for example, a manipulator) are used to clamp the workpiece tooling combination to complete the related processing or assembly work . When the workpiece tooling assembly is removed from the processing execution end, the workpiece tooling assembly is removed as a whole, and when it needs to be operated again, the workpiece tooling assembly can be installed again. In multiple clamping, the tubular workpiece and the tooling, that is, the clamping and positioning device are mechanically connected, and the relative position is fixed, and the tooling and the processing execution end are connected by a zero-point positioning system, so it can ensure that the repeated installation of the tubular workpiece and the processing execution Consistency of end posture. When all the processes that require positioning assurance are completed, loosen the clamping parts of the tooling.
[0081] By rotating the knob of the locking bolt, the pipe fitting is fixed with the clamping and positioning device provided by the present invention, and forms a workpiece tooling assembly.
[0082] The specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which does not affect the essence of the present invention. In the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other arbitrarily.
