[0002] Gear machining tools are mechanical equipment specifically designed for processing gears. Gears are widely used in mechanical transmission. Gear machining tools use specific cutting tools and processes, such as hobbing, shaping, and milling, to process workpieces into precise gear shapes and sizes. These machine tools need to ensure high transmission accuracy and stability to ensure the accuracy of gear meshing and service life.
[0003] Flexible tooling is used for gear clamping in gear processing machine tools. Its core function is to improve the versatility, adaptability and accuracy of gear clamping in order to meet the processing needs of multi-variety, small-batch production and complex gears. Flexible tooling usually has good positioning accuracy and clamping stability, which can ensure that the gear maintains a precise position and posture during processing, reduce processing errors, and thus improve the processing accuracy and quality of the gear.
[0004] However, existing flexible tooling has a cumbersome replacement process after clamping the gears, and the operation is time-consuming. Moreover, when unlocking is achieved by pneumatic means, the stability and reliability are poor, far inferior to the accuracy and response speed of mechanical unlocking. It is easy to generate potential errors during the processing switch. Therefore, in order to solve the above problems, a quick switching mechanism for flexible tooling for gear processing machine tools is proposed. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0031] Please see Figures 1-8 This utility model provides a technical solution:
[0032] A flexible tooling quick-change mechanism for a gear processing machine tool includes a cylinder 1 and a pneumatic disc 2. The pneumatic disc 2 is bolted to one side of the cylinder 1. A pneumatic flexible positioner 3 is inserted inside the pneumatic disc 2. A rotating ring assembly 4 is mounted on the outside of the pneumatic flexible positioner 3. A limit assembly 5 is fixedly installed in the pneumatic flexible positioner 3. A positioning assembly 6 is inserted in the pneumatic flexible positioner 3. The pneumatic flexible positioner 3 includes a grooved column 31. A stop column 32 is slidably disposed inside the grooved column 31. An inter-column groove 33 is formed on the outside of the grooved column 31. A through hole 34 is formed inside the grooved column 31. A blind hole 35 is formed in the grooved column 31. The rotating ring assembly 4 includes a grooved ring 41, which is fixedly connected to a limiting block 42. A notch 43 is provided on the inner side of the grooved ring 41, and a pressing block 44 is welded and fixed in the notch 43. The limiting assembly 5 includes an insert plate 51, with a connecting spring 52 fixedly connected to the upper end of the insert plate 51 and a locking block 53 fixedly connected to the bottom end of the insert plate 51. The positioning assembly 6 includes a support block 61, with a locking groove 62 provided on the side of the support block 61 near the limiting assembly 5. A guide post 63 is fixedly connected on the side of the support block 61 near the pneumatic flexible positioner 3, and a return spring 64 is fixedly connected on the side of the support block 61 near the pneumatic flexible positioner 3.
[0033] As a further implementation of this solution, multiple limit components 5 are provided. The multiple limit components 5 are arranged in a ring array in the pneumatic flexible positioner 3. The position of the positioning component 6 corresponds one-to-one with the position of the pneumatic flexible positioner 3. The setting of multiple limit components 5 can help fix the position of the positioning component 6, thereby enabling the positioning component 6 to provide more stable support for the gear.
[0034] As a further implementation of this solution, the upper end of the abutment 32 is arc-shaped, the groove 33 between the columns is annular, the inner side of the through hole 34 is in close contact with the outer side of the guide post 63, and the guide post 63 is slidably disposed in the through hole 34. The arc shape of the upper end of the abutment 32 can prevent rigid collisions that could damage the guide post 63 when the abutment 32 comes into contact with the guide post 63. The design that the inner side of the through hole 34 is in close contact with the outer side of the guide post 63 makes the movement of the guide post 63 more stable and precise.
[0035] As a further implementation of this solution, the inner diameter of the grooved ring 41 is the same as the outer diameter of the grooved column 31, the central axis of the grooved ring 41 and the central axis of the grooved column 31 are on the same vertical line, the bottom end face of the grooved ring 41 is in contact with the upper end face of the support block 61, and the limiting block 42 is set in an "L" shape. The positional relationship between the grooved ring 41 and the grooved column 31 can make the rotation of the grooved ring 41 on the grooved column 31 more stable, and the setting of the limiting block 42 can prevent the grooved ring 41 from falling off the grooved column 31.
[0036] As a further implementation of this solution, the number of slots 43 is the same as the number of limiting components 5. The pressing blocks 44 are distributed in pairs in the slots 43. One end of the pressing block 44 is arc-shaped. When the pressing block 44 contacts the limiting component 5, its arc shape allows it to better lift the insert plate 51, thereby causing the card block 53 to disengage from the card slot 62.
[0037] As a further implementation of this solution, multiple slots 62 are provided. The vertical cross-sectional shape of the slot 62 is a right triangle. Part of the return spring 64 is set in the blind hole 35. The side of the support block 61 away from the pneumatic flexible positioner 3 is arc-shaped. The shape of the slot 62 allows the guide post 63 to be stably engaged in the slot 62, so that the support block 61 cannot be squeezed back into the inter-post groove 33.
[0038] As a further implementation of this solution, a grooved post 31 is fixedly connected to the upper end of the connecting spring 52. The outer side of the insert plate 51 is in close contact with the inner side of the limiting groove 36. The shape of the locking block 53 is composed of half a cylinder and a quarter ball. Part of the locking block 53 is set in the locking groove 62. The design of the outer side of the insert plate 51 being in close contact with the inner side of the limiting groove 36 makes the movement of the insert plate 51 in the limiting groove 36 more stable. The shape of the locking block 53 can better fit the locking groove 62, thereby achieving the function of unidirectional limiting.
[0039] Working process: When the device is in use, the gear workpiece to be processed is passed through the pneumatic flexible positioner 3 and then placed on the positioning assembly 6. At this time, the starting cylinder 1 controls the pneumatic disc 2 to start by injecting compressed air into the pneumatic disc 2, and applies force to the abutment 32 set in the grooved column 31, causing the abutment 32 to move and squeeze the guide column 63 inserted in the pneumatic flexible positioner 3, causing the guide column 63 to slide in the through hole 34. As the guide column 63 moves, it will drive the fixedly connected support block 61 to move. At the same time as the support block 61 moves, the return spring 64 is also stretched, which can prevent the support block 61 from moving too fast and becoming unstable. At the same time, due to the change in the relative position of the support block 61 and the insertion plate 51, the relative position of the slot 62 will also change with the relative position of the locking block 53 fixedly connected to the bottom end of the insertion plate 51. Under the action of the elastic force generated by the connecting spring 52, the insertion plate 51... The guide post 63 is engaged in the slot 62 due to the shape of the slot 62 and the special shape of the guide post 53. The support block 61 cannot be squeezed back into the inter-column groove 33, thus providing stable support for the gear workpiece. The gear can then be processed. After the gear is processed, the relative position of the notch 43 and the insert plate 51 can be changed by rotating the grooved ring 41. When the grooved ring 41 rotates, part of the limiting block 42 is engaged in the inter-column groove 33 to ensure that the rotation of the grooved ring 41 is more stable. At this time, one end of the pressing block 44 will contact the insert plate 51 and push the insert plate 51, thereby causing the guide post 53 to disengage from the slot 62. The abutment post 32 is reset by the pneumatic disc 2, and the support block 61 will be reset under the tension generated by the return spring 64, so that the gear workpiece can be easily removed.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
