[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] like Figure 1-4 As shown, a quick positioning fixture for metal processing includes:

[0032] Base 1;

[0033] Support rods 3 arranged in a circular array on the base 1 and slidingly fitted therewith;

[0034] Rotate the first positioning block 7 disposed on the side wall of the support rod 3;

[0035] A second positioning block 8 is rotatably disposed on the side wall of the support rod 3, and the second positioning block 8 is coaxially arranged with the first positioning block 7;

[0036] The locking assembly at least comprises buckles 4 arranged in a circumferential array in the support rod 3 and driven to be engaged in the first positioning block 7 and the second positioning block 8 .

[0037] Specifically, the first positioning block 7 and the second positioning block 8 installed on the support rod 3 are simultaneously rotated in opposite directions, so that a 45° angle is formed between the first positioning block 7 and the second positioning block 8, and the buckle 4 is driven to be clamped on the first positioning block 7 and the second positioning block 8, so that the first positioning block 7 and the second positioning block 8 forming a 45° angle are fixed, and the first positioning block 7 and the second positioning block 8 forming a 45° angle are pushed by the support rod 3 to move the four diagonal corners of the metal part in the direction at the same time, so that the first positioning block 7 and the second positioning block 8 cooperate with each other to clamp the four diagonal corners of the square metal part, so that the tooling can quickly position the square metal part. When the tooling needs to position the cylindrical metal part By turning the first positioning block 7 and the second positioning block 8 in opposite directions to form an angle of 120°, the first positioning block 7 and the second positioning block 8 can better fit on the side wall of the cylindrical metal part. After the buckle 4 fixes the first positioning block 7 and the second positioning block 8, the first positioning block 7 and the second positioning block 8 formed with an angle of 120° are pushed by the support rod 3 to abut against the side wall of the cylindrical metal part at the same time, so that the cylindrical metal part is stably clamped, so that the tooling can quickly position the cylindrical metal part. By adjusting the angle between the first positioning block 7 and the second positioning block 8 to 120°, the tooling can not only position the square metal part, but also the cylindrical metal part.

[0038] In the above embodiment, by arranging the support rod 3, the first positioning block 7, the second positioning block 8 and the buckle 4 on the base 1, the tooling can position the square metal piece and the cylindrical metal piece, by turning the first positioning block 7 and the second positioning block 8 to rotate and form a 45° angle, and fixing the first positioning block 7 and the second positioning block 8 by the buckle 4, the support rod 3 can push the first positioning block 7 and the second positioning block 8 to clamp the four diagonal corners of the square metal piece, so that the tooling can position the square metal piece and clamp the four corners of the metal piece, which can better ensure that the square metal piece is loaded. In order to improve the stability during the machining process, the first positioning block 7 and the second positioning block 8 are expanded to a 120° angle by moving the first positioning block 7 and the second positioning block 8 so that the first positioning block 7 and the second positioning block 8 can fit on the side wall of the cylindrical metal part, and the cylindrical metal part is clamped by the first positioning block 7 and the second positioning block 8 installed on the multiple support rods 3, so that the tooling can position the cylindrical metal part, so that the tooling can not only accurately position the square metal part, but also accurately and stably position the cylindrical metal part, which solves the problem that the tooling cannot stably position the cylindrical metal part and improves the stability of the cylindrical metal part during machining.

[0039] As an embodiment further provided by the present invention, a groove 10 is formed at the top of the support rod 3 , a buckle 4 is movably connected in the groove 10 , an elastic frame 5 is fixedly installed in the groove 10 , and the side wall of the elastic frame abuts against the buckle 4 .

[0040] Specifically, the elastic frame 5 installed in the groove 10 provides a thrust to the buckle 4, so that the buckle 4 abuts against the inner walls of the first positioning block 7 and the second positioning block 8. When the first positioning block 7 and the second positioning block 8 rotate, the first positioning block 7 and the second positioning block 8 simultaneously push the buckle 4 to squeeze the elastic frame 5 to deform and slide into the groove 10, so that the first positioning block 7 and the second positioning block 8 can rotate stably, thereby adjusting the angle.

[0041] As another embodiment further provided by the present invention, a pin shaft 6 is movably installed in the elastic frame 5 .

[0042] Specifically, when the first positioning block 7 and the second positioning block 8 need to be fixed, the pin 6 is inserted into the elastic frame 5 so that the pin 6 supports the elastic frame 5, thereby preventing the elastic frame 5 from deforming. When the elastic frame 5 cannot be deformed, the buckle 4 cannot move into the groove 10, so that the buckle 4 can fix the first positioning block 7 and the second positioning block 8.

[0043] As another embodiment further provided by the present invention, a mounting groove 11 is provided in the support rod 3 , the mounting groove 11 is communicated with the groove 10 , a spring 12 is fixedly installed in the mounting groove 11 , and one end of the spring 12 is movably connected to the pin 6 .

[0044] Specifically, the spring 12 installed in the mounting groove 11 provides a pulling force to the pin 6, so that the pin 6 is always fixed in the elastic frame 5 when there is no manual pulling, thereby preventing the buckle 4 from loosening during workpiece processing. When the first positioning block 7 and the second positioning block 8 need to be rotated, the pin 6 is manually pulled out so that the pin 6 can be separated from the elastic frame 5, thereby improving the stability of the workpiece during processing.

[0045] As another embodiment further provided by the present invention, a slide groove 2 is provided at the top of the base 1, and a support rod 3 is movably connected in the slide groove 2.

[0046] Furthermore, a hydraulic cylinder 14 is fixedly mounted on the bottom end of the base 1 , a pull rod 13 is fixedly mounted on the hydraulic cylinder 14 , and one end of the pull rod 13 is fixedly connected to the support rod 3 .

[0047] Specifically, the hydraulic cylinder 14 pulls the pull rod 13, so that the pull rod 13 can pull the support rod 3 to move along the slide groove 2 toward the axis of the base 1, so that the support rod 3 can push the first positioning block 7 and the second positioning block 8 to position the square metal part or cylindrical metal part placed on the base 1.

[0048] Working principle: When the tooling needs to fix the square metal piece, the first positioning block 7 and the second positioning block 8 are rotated in opposite directions to form a 45° angle between the first positioning block 7 and the second positioning block 8, and the pin shaft 6 is pushed to be fixed in the elastic frame 5, so that the buckle 4 is clamped on the first positioning block 7 and the second positioning block 8 to lock, so that the first positioning block 7 and the second positioning block 8 are locked. When the first positioning block 7 and the second positioning block 8 are fixed, the hydraulic cylinder 14 provides a pulling force to the pull rod 13, so that the pull rod 13 pulls the support rod 3 to slide along the slide groove 2 toward the axis of the base 1, so that the support rod 3 pushes the first positioning block 7 and the second positioning block 8 to clamp the four diagonal corners of the square metal piece, so that the tooling can fix the square metal block. Positioning, when the tooling needs to fix the cylindrical metal part, by pulling the pin shaft 6 out of the elastic frame 5, the buckle 4 releases the lock on the first positioning block 7 and the second positioning block 8, and by rotating the first positioning block 7 and the second positioning block 8 to form an angle of 120°, the first positioning block 7 and the second positioning block 8 can better fit on the side wall of the cylindrical metal part, and the first positioning block 7 and the second positioning block 8 are fixed again by the buckle 4 to prevent the first positioning block 7 and the second positioning block 8 from loosening, and the first positioning block 7 and the second positioning block 8 formed at an angle of 120° are pushed by the support rod 3 to abut against the side wall of the cylindrical metal part at the same time, so that the cylindrical metal part is fixed, and the tooling can position the cylindrical metal part.

[0049] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
