[0028] During the parts processing process, a positioning fixture is needed to position the parts, and then the cutting process is achieved by rotating the fixture. The existing positioning fixtures usually clamp and position the parts of the same series and the same size and model, and then process them. When encountering parts of the same series but different sizes and models, it is necessary to replace the corresponding positioning fixtures. When facing multiple different models of parts at the same time, the fixtures need to be replaced frequently, resulting in a long processing cycle. The frequent replacement of workers results in high labor intensity and low processing efficiency.

[0029] See also Figures 1 to 5 The present application provides a rotation positioning fixture, including a base plate 1, a first rotating disk 2, a second rotating disk 3 and a positioning sleeve 4. The base plate 1 is provided with two groups of positioning holes. The first rotating disk 2 is installed at one end of the base plate 1. The first rotating disk 2 is provided with a first connecting hole for connecting a rotating device. The second rotating disk 3 is installed at the other end of the base plate 1. The second rotating disk 3 is provided with a second connecting hole 3a for connecting a rotating device. There are multiple positioning sleeves 4, and the inner diameters of each positioning sleeve 4 are different. The positioning sleeves 4 are aligned with the positioning holes and can be detachably installed on the base plate 1.

[0030] During use, the first connecting hole and the second connecting hole 3a are connected to the four-axis power head on the workbench of the machining center, and the part 10 is assembled in the positioning sleeve 4 for positioning. When the power head rotates, the rotating positioning fixture drives the part 10 to be cut from multiple directions. When it is necessary to process other types of parts 10, the positioning sleeve 4 is directly removed from the base plate 1 and replaced with a positioning sleeve 4 suitable for the type of part 10. There is no need to replace the entire positioning fixture, thereby reducing the labor intensity of manpower. In addition, different types of positioning sleeves 4 can be installed in each group of positioning holes, so that the processing of multiple types of parts 10 can be completed at one time, which essentially plays a role of quick change and effectively improves the processing efficiency.

[0031] The bottom plate 1 is a rectangular flat plate structure. The first rotating disk 2 and the second rotating disk 3 are both disc structures. The first rotating disk 2 and the second rotating disk 3 are respectively vertically fixed on the short sides of the bottom plate 1 on both sides.

[0032] In some embodiments, the first rotating disk 2 and the second rotating disk 3 are both detachably connected to the bottom plate 1. Specifically, a boss is provided in the middle of the first rotating disk 2 and the middle of the second rotating disk 3, and a threaded hole is provided on the boss. Small holes are provided on the two short sides of the bottom plate 1. The boss on the first rotating disk 2 fits on the bottom surface of the bottom plate 1, and the boss on the second rotating disk 3 fits on the bottom surface of the bottom plate 1. Then, bolts are passed through the threaded holes and the small holes to connect the boss to the bottom plate 1 through nuts. This installation method facilitates the subsequent disassembly and replacement of the first rotating disk 2 and the second rotating disk 3.

[0033] In some embodiments, the positioning sleeve 4 includes a first positioning ring 4a and a second positioning ring 4b. The first positioning ring 4a is aligned with the positioning hole and can be removably installed on the base plate 1. The second positioning ring 4b is aligned with the first positioning ring 4a and can be removably installed on the first positioning ring 4a. The inner diameter of the second positioning ring 4b is smaller than the inner diameter of the first positioning ring 4a.

[0034] Specifically, the first positioning ring 4a is aligned with the positioning hole and fixed to the bottom plate 1 by bolts, the second positioning ring 4b is fixed to the first positioning ring 4a by bolts, the second positioning ring 4b is concentrically arranged with the first positioning ring 4a, the first positioning ring 4a and the second positioning ring 4b together form a positioning sleeve 4, and the part 10 to be processed is directly assembled in the second positioning ring 4b. The positioning sleeve 4 assembled by two positioning rings is less difficult to process.

[0035] Of course, in addition to being a structure formed by assembling two positioning rings, the structure of the positioning sleeve 4 can also be directly set as a structure formed by two positioning rings or multiple positioning rings being integrally formed.

[0036] In the embodiment shown in the present application, a first bushing 40a is provided on the first positioning ring 4a, and the first bushing 40a is inserted into the positioning hole.

[0037] Specifically, the first bushing 40a is a cylindrical structure, and the first bushing 40a is vertically fixed on the first positioning ring 4a. The inner diameter of the first bushing 40a is the same as the inner diameter of the first positioning ring 4a. During the installation process, the first bushing 40a is inserted into the positioning hole, and then the first positioning ring 4a is fixed on the base plate 1.

[0038] In some other embodiments, a second bushing 40b is provided on the second positioning ring 4b, and the second bushing 40b is nested in the first bushing 40a.

[0039] Specifically, the second bushing 40b is vertically fixed on the second positioning ring 4b, and the inner diameter of the second bushing 40b is the same as the inner diameter of the second positioning ring 4b. During the installation process, the second bushing 40b is nested inside the first bushing 40a, and then the second positioning ring 4b is pressed on the first positioning ring 4a to connect the two by bolts. When in use, the part 10 is directly assembled in the second bushing 40b, so that it can be installed more stably.

[0040] In order to make the part 10 more firmly installed on the fixture of the present application during the rotation processing, in some embodiments, the present application also includes a clamping device 5, which is used to clamp the part 10 in two adjacent positioning sleeves 4.

[0041] In some embodiments, the clamping device 5 includes a pressing rod 5a and a pulling rod 5b, wherein both ends of the pressing rod 5a are used to clamp on the two parts 10, one end of the pulling rod 5b is connected to the pressing rod 5a, and the other end of the pulling rod 5b is used to connect to the driving cylinder.

[0042] Specifically, the driving cylinder is arranged under the base plate 1, and each group of positioning holes includes two positioning holes. A through hole for the pull rod 5b to pass through is provided on the base plate 1 between the two positioning holes. The aperture of the through hole is larger than the rod diameter of the pull rod 5b. The middle part of the pressure rod 5a is vertically fixed to one end of the pull rod 5b, and the other end of the pull rod 5b is connected to the driving cylinder. During operation, the driving cylinder drives the pull rod 5b, and the pull rod 5b pulls the pressure rod 5a to press on the two parts 10, thereby fixing the part 10 in the positioning sleeve 4.

[0043] In order to prevent the pressing rod 5a from sliding and misaligning relative to the part 10, in some embodiments, a positioning groove 50a is provided on one end of the pressing rod 5a for pressing the part 10, and the positioning groove 50a is used to cooperate with the protrusion 10a on the part 10.

[0044] In some other embodiments, a positioning groove 50a is provided on one end of the pressing rod 5a for pressing the part 10. The positioning groove 50a is used to correspond to the groove 10b on the part 10, and a positioning shaft is assembled in the positioning groove 50a and the groove 10b.

[0045] For example, in the present application, one group of parts 10 is provided with a protrusion 10a, and the other group of parts 10 is provided with a groove 10b. For the part 10 with the protrusion 10a, the groove 10b on the pressure rod 5a can be directly put on it, and the positioning of the part 10 and the pressure rod 5a is achieved through the cooperation of the protrusion 10a and the groove 10b. For the part 10 with the groove 10b, the positioning shaft is first assembled in the groove 10b of the part 10, and then the positioning groove 50a on the pressure rod 5a is put on the positioning shaft, thereby achieving the positioning of the pressure rod 5a and the part 10.
