DETAILED DESCRIPTION

[0016] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. The descriptions of "left" and "right" in the present invention are all based on Figure 1 For reference direction:

[0017] like Figure 1 to Figure 3As shown, a fixed-angle rotating mechanism is fixedly installed on a workbench 1. The workbench 1 is used for processing clutch parts. It includes a rotating frame 2 and a rotating drive assembly 3. A column 11 is fixedly installed on the workbench 1. The rotating frame 2 is rotatably installed on the column 11. The rotating frame 2 can be fixedly connected to the part tooling. The rotation of the rotating frame 2 can meet the steering requirements of the part. The rotating frame 2 includes a ratchet drive disk 21 and an angle positioning disk 22. The ratchet drive disk 21 and the angle positioning disk 22 are fixedly connected to each other. The rotating drive assembly 3 is installed on the workbench 1. The rotating drive assembly 3 is transmission-connected to the ratchet drive disk 21. The workbench 1 is also equipped with an angle The angle positioning component 4 can be connected to the angle positioning disk 22. The ratchet drive disk 21 is the driving part on the rotating frame 2. The fixed angle rotation of the entire rotating frame 2 can be achieved by the rotation drive component 3, and the fixed angle steering of the parts can be achieved. The angle positioning disk 22 is the positioning part on the rotating frame 2. The angle positioning disk 22 can be inserted and fixed by the angle positioning component 4, so that the entire rotating frame 2 can be kept at a fixed angle to meet the processing requirements of the parts at this angle position. The rotation drive component 3 and the angle positioning component 4 adopt an alternating mode to ensure that the steering and positioning functions do not conflict.

[0018] like Figure 3 As shown, the ratchet drive disk 21 is rotatably mounted on the column 11, the angle positioning disk 22 is fixedly stacked on the ratchet drive disk 21, and a tool fixing disk 23 is also fixedly stacked above the angle positioning disk 22. The ratchet drive disk 21, the angle positioning disk 22 and the tool fixing disk 23 are combined into a complete rotating frame 2 component. This rotating frame 2 component can rotate as a whole, and the tool fixing disk 23 can be bolted through to connect the parts to clamp the tooling.

[0019] like Figure 2 As shown, a plurality of evenly distributed ratchet teeth 211 in the same direction are arranged on the outer edge of the ratchet drive disk 21, and a plurality of evenly distributed positioning notches 221 are opened on the outer edge of the angle positioning disk 22. The number of positioning notches 221 and ratchet teeth 211 are consistent and arranged one-to-one, so that the rotating frame 2 can be effectively positioned every time it rotates one angle grid.

[0020] like Figure 2As shown, the rotary drive assembly 3 includes a first cylinder frame 31, a rotary drive cylinder 32, a rotating arm 33 and a spring 36. The first cylinder frame 31 is fixedly mounted on the workbench 1. The tail end of the rotary drive cylinder 32 is hingedly connected to the first cylinder frame 31. One end of the rotating arm 33 is rotatably connected to the column 11, and the other end is connected to the piston end of the rotary drive cylinder 32. A pawl 34 is rotatably mounted on the rotating arm 33. A spring seat 35 is also fixedly mounted on the rotating arm 33. One end of the spring 36 is connected to the spring seat 35, and the other end is connected to the pawl 34. Under the elastic force of the spring 36, the pawl 34 can maintain contact with the outer edge wall of the ratchet drive disk 21. When the piston rod of the rotary drive cylinder 32 is extended or retracted, the rotating arm 33 can be driven to rotate, and then the overall rotation of the rotating frame 2 is driven by the cooperation between the pawl 34 and the ratchet 211. Each time the piston rod of the rotary drive cylinder 32 is extended or retracted, the pawl 34 advances one grid, that is, it advances one angle of the ratchet 211. Under the coordinated movement of the pawl 34 and the ratchet 211, the fixed-angle intermittent rotation of the rotating frame 2 can be realized, and the rotation direction of the parts is also fixed.

[0021] like Figure 1 As shown, the angle positioning assembly 4 includes a second cylinder frame 41 and a positioning cylinder 42. The second cylinder frame 41 is fixedly mounted on the workbench 1. The positioning cylinder 42 is fixedly connected to the second cylinder frame 41. The piston rod end of the positioning cylinder 42 is connected with a positioning block 43. The positioning block 43 is arranged and installed corresponding to the angle positioning disk 22. When the piston rod end of the positioning cylinder 42 extends outward, the positioning block 43 can be inserted into the angle positioning disk 22 (that is, the position of the positioning notch 221). Since the positioning cylinder 42 is fixed, the angle positioning disk 22 can be positioned and fixed, so that the entire rotating frame 2 components can be fixed and the existing steering direction can be maintained.

[0022] like Figure 1 As shown, the positioning notch 221 adopts a wedge-shaped notch, and the size of the positioning block 43 matches the positioning notch 221. The fixed-angle rotation achieved by the rotating drive component 3 will have a certain rotation error. Although the error is small, it will also affect the processing accuracy of the parts. Therefore, the utility model designs the positioning notch 221 and the positioning block 43 to be wedge-shaped. The wedge shape is characterized by having large and small openings, and the large and small openings allow the two to have a plug-in margin when plugged in. In this way, the insertion of the positioning block 43 can have a certain correction and adjustment effect (it can reverse a slight steering deviation) to ensure the accuracy of the rotation direction of the parts to meet the precise processing requirements of the parts.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
