Abstract
Description
Technical Field
[0001] This application relates to the field of rotary table technology, specifically a high-speed indexing servo hollow equally divided rotary table. Background Art
[0002] A rotary table is a machine tool accessory with a rotatable table surface used to clamp workpieces and achieve rotation and indexing positioning. It is also called a rotary table or fourth axis. It is usually mounted horizontally on the machine tool table. During operation, it uses the machine tool's control system or a specially matched control system to complete various indexing and rotary movements coordinated with the machine tool.
[0003] For example, the patent with publication number CN216911969U discloses a forging rotary table. This patent rotates through mechanical transmission of a worm gear, eliminating the need for manual operation. Through the set rotation support components and load-bearing cavity, it can withstand the impact of forged parts and has strong stability.
[0004] However, most existing rotary tables use worm gear transmission and hydraulic locking, resulting in slow tool change speed and low efficiency. Some servo rotary tables using direct drive transmission lack a hollow structure, which cannot meet the requirements for reasonable pipeline layout. Furthermore, they lack a reduction mechanism, which places high demands on the performance parameters of the motor itself, hindering the standardization of servo motor and driver selection.
[0005] Therefore, it is necessary to provide a high-speed indexing servo hollow equally divided rotary table to solve the above problems.
[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention
[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a high-speed indexing servo hollow equally divided rotary table, which solves the problem that the lack of reasonable space utilization for pipeline arrangement and the absence of a deceleration mechanism when driving the rotary table leads to high requirements for the performance parameters of the motor itself, which is not conducive to the universal selection of servo motors and drivers.

[0018] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0020] like Figure 1-Figure 2 As shown, this application provides a high-speed indexing servo hollow equally divided rotary table, including a rotary table 1, which is placed in a machining center or an automatic milling machine to facilitate the processing of parts; The rotary table 1 includes a housing 21, which has a cavity inside. A cover plate 11 is fixedly installed at the lower end of the cavity. A central shaft 12 is rotatably installed inside the cavity at the upper end of the cover plate 11. A large gear 13 is fixedly installed on the outside of the central shaft 12. Meanwhile, a motor cover 10 is fixedly installed on one side of the housing 21. A motor 20 is fixedly installed inside the motor cover 10. The output end of the motor 20 passes through the housing 21 and enters the internal cavity. A small gear 14 is fixedly installed at the output end of the motor 20. The small gear 14 meshes with the large gear 13, thereby starting the motor 20. Through the meshing of the small gear 14 with the large gear 13, the central shaft 12 is driven to rotate inside the cavity. Furthermore, a worktable 19 is rotatably provided on the upper end of the housing 21. Multiple sets of mounting slots 24 are provided on the worktable 19. In this application, a pneumatic or hydraulic chuck is detachably provided in the mounting slot 24 to facilitate the clamping of the workpiece to be processed. Meanwhile, the bottom of the worktable 19 has a protruding end that extends into the cavity and is fixedly connected to the top of the central shaft 12. Thus, when it is necessary to perform multi-directional machining on the workpiece or to change to a tool corresponding to the workpiece's orientation, the motor 20 can be started to drive the worktable 19 to rotate on the upper part of the housing 21 via the central shaft 12. This allows the workpiece to be rotated to the corresponding orientation after tool change for subsequent machining. It should be noted that both the large gear 13 and the small gear 14 mentioned above are bevel gears, which have their own reduction ratio when rotating, thus achieving a 45-degree indexing in only 0.3 seconds and a 180-degree indexing in only 0.6 seconds, so as to facilitate rapid indexing and improve processing efficiency. In addition, in this application, the motor 20 connecting sleeve is standardized in design, thus achieving a high degree of versatility. Meanwhile, in order to lock the worktable 19 and prevent it from shaking during processing, a hydraulic cylinder 15 is fixedly installed inside the cavity at the upper end of the large gear 13, and a locking disc 16 is fixedly installed at the output end of the hydraulic cylinder 15. The upper end of the locking disc 16 has multiple sets of locking teeth, and multiple sets of oil inlets 22 are provided on one side of the housing 21. At the same time, multiple sets of oil chambers are provided between the hydraulic cylinder 15 and the locking disc 16. These multiple sets of oil chambers are connected to the multiple sets of oil inlets 22, so that the locking disc 16 can be pushed vertically up and down along the central axis 12 by driving the hydraulic cylinder 15. Meanwhile, an internal gear ring 18 is fixedly installed at the connection between the central shaft 12 and the worktable 19, and an external gear ring 17 is fixedly installed outside the internal gear ring 18. The lower ends of the internal gear ring 18 and the external gear ring 17 are provided with meshing teeth, and these meshing teeth are adapted to the locking teeth at the upper end of the locking disc 16. Thus, when it is necessary to perform locking operations on the worktable 19, oil can be injected into the oil inlet 22, thereby guiding the oil into the space between the oil cylinder 15 and the locking disc 16. The locking plate 16 is driven by the hydraulic cylinder 15 in the oil chamber to move vertically upward along the central axis 12 until the locking teeth at the upper end of the locking plate 16 engage with the meshing teeth, thereby locking the worktable 19. When unlocking is required, oil is injected into the corresponding oil chamber of the locking plate 16 through the oil injection port 22, which will drive the hydraulic cylinder 15 to move the locking plate 16 away from the inner gear ring 18 and the outer gear ring 17, thereby unlocking the worktable 19, so as to facilitate subsequent multi-directional processing of the workpiece. It should be noted that the central shaft 12, the worktable 19, and the cover plate 11 are hollow to facilitate the subsequent arrangement of pipelines. Furthermore, a proximity switch 25 is fixedly installed at one end of the housing 21. The proximity switch 25 is used to receive the signal that the rotary table 1 has finished rotating and locked and then feeds it back to the external receiver so as to facilitate the subsequent replacement of the tool corresponding to the workpiece position. At the same time, an end cover 23 is detachably installed on the outside of the proximity switch 25. The end cover 23 is used to protect the proximity switch 25 from contamination during use.
[0021] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
