Description

Technical Field

[0001] This utility model relates to the field of CNC machining technology, specifically a novel CNC rotary table for cam rollers. Background Technology

[0002] A CNC rotary table needs to be installed on the machine tool workbench of a CNC machining center. The workpiece is then clamped onto the CNC rotary table, and the machine tool can perform machining on the workpiece at any angle and on linked curved surfaces. Most existing CNC rotary tables are worm gear and worm shaft structures. The meshing transmission of the worm gear and worm shaft structure is a sliding friction transmission. However, current CNC rotary tables lack corresponding oil lubrication functions, which results in greater wear on the worm gear and worm shaft during operation. This reduces the service life of the worm gear, worm shaft, and the entire CNC rotary table. Furthermore, when lubricating the worm gear and worm shaft, the entire CNC rotary table needs to be stopped and waited for, which affects the working efficiency of the CNC rotary table and has obvious defects.

[0003] To address this, a novel cam roller CNC rotary table is proposed. Utility Model Content

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.

[0035] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0036] Example 1:

[0037] Please see Figure 1-7This utility model provides a technical solution: To achieve the above objectives, this utility model provides the following technical solution: A novel cam roller CNC rotary table, comprising: a first outer shell 1; a mounting hole 2 is provided on the top of the first outer shell 1, a bearing 3 is installed in the mounting hole 2, a connecting rod 4 is installed inside the bearing 3, a rotary worktable 32 is fixed on the top of the connecting rod 4, and a cam 5 located inside the first outer shell 1 is fixed on the bottom of the connecting rod 4; a second outer shell 6 is installed on the right side of the first outer shell 1; a servo motor 7 is installed inside the second outer shell 6, and a worm gear 8 meshing with the cam 5 is fixed at the output end of the servo motor 7; a mounting groove 9 is provided on the front side of the first outer shell 1; a container 10 is installed in the mounting groove 9, and the container 10 is filled with lubricating oil; a pump 11 is installed at the bottom of the container 10, and a connecting pipe 12 penetrating the outer wall of the container 10 is installed at the outlet end of the pump 11, and a nozzle 13 is installed at one end of the connecting pipe 12; the nozzle 13 is located at the meshing point of the worm gear 8 and the cam 5. Above; a receiving plate 15 is provided inside the first outer shell 1, and a collection pool 16 is fixed on the top of the receiving plate 15; the collection pool 16 is located below the worm gear 8 and the cam 5, a limiting ear 14 is fixed on the inner wall of the first outer shell 1, the receiving plate 15 abuts against the bottom of the limiting ear 14, a connecting ear 17 is fixed on the bottom of the receiving plate 15, a threaded hole 18 is opened on the outer wall of the connecting ear 17, a locking hole 19 is opened on the inner wall of the first outer shell 1, a threaded locking rod 20 is threadedly connected to the threaded hole 18, a knob 21 is fixed at one end of the threaded locking rod 20, and the other end of the threaded locking rod 20 is locked inside the locking hole 19, a filter element is provided inside the collection pool 16, the filter element is composed of a connecting frame 23 and a filter screen 24, the filter screen 24 is installed inside the connecting frame 23, a limiting frame 22 is fixed on the inner wall of the collection pool 16, the connecting frame 23 abuts against the top of the limiting frame 22, a first limiting hole 25 is opened on the outer wall of the collection pool 16, and a second limiting hole 26 is opened on the outer wall of the connecting frame 23.

[0038] Specifically, this invention activates pump 11, which causes lubricating oil inside container 10 to enter nozzle 13 through connecting pipe 12. The oil is then sprayed from nozzle 13 onto the meshing point of worm 8 and cam 5, thus lubricating the worm 8 and cam 5. Compared to existing technologies, this invention has the function of automatically lubricating worm 8 and cam 5. By lubricating worm 8 and cam 5, the service life of worm 8, cam 5, and the entire CNC rotary table can be improved. Since the lubrication of worm 8 and cam 5 is automatic, the CNC rotary table does not need to stop and wait, thereby ensuring the working efficiency of the CNC rotary table and solving the defects existing in the prior art.

[0039] Since a receiving plate 15 is provided inside the first housing 1, and a collection pool 16 is fixed on the top of the receiving plate 15, when the worm gear 8 and cam 5 are lubricated, the falling lubricating oil will fall into the collection pool 16, achieving the purpose of recycling the lubricating oil. On the one hand, it can avoid the lubricating oil from polluting the internal environment of the first housing 1, and on the other hand, it can recycle and reuse the lubricating oil, which is relatively energy-saving and environmentally friendly.

[0040] Example 2:

[0041] Please see Figure 5-7 This utility model provides a technical solution: a novel cam roller CNC turntable, wherein a vertical bar 27 is fixed to the top of the receiving plate 15, a telescopic rod 28 is fixed to the outer wall of the vertical bar 27, a connecting plate 29 is fixed to one end of the telescopic rod 28, and a limiting pin 30 is fixed to one end of the connecting plate 29, which is engaged with the first limiting hole 25 and the second limiting hole 26; a spring 31 is provided on the outside of the telescopic rod 28; one end of the spring 31 is fixed to the vertical bar 27, and the other end of the spring 31 is fixed to the outer wall of the collection pool 16.

[0042] Please refer to Embodiment 1. By providing a filter element inside the collection pool 16, which consists of a connecting frame 23 and a filter screen 24, the lubricating oil will pass through the filter screen 24 before falling into the collection pool 16. The filter screen 24 will filter out impurities inside the lubricating oil, thereby improving the purity of the lubricating oil and increasing the efficiency of subsequent lubricating oil recycling.

[0043] Furthermore, the screw rod 20 is moved within the threaded hole 18 by the knob 21. After one end of the screw rod 20 disengages from the hole 19, the receiving plate 15 will not abut against the limiting ear 14. The receiving plate 15 will then be removed from the first outer shell 1. Subsequently, the telescopic rod 28 and spring 31 are driven to retract on the outer wall of the vertical bar 27. When the telescopic rod 28 retracts, it will drive the connecting plate 29 and the limiting pin 30 to move. After the limiting pin 30 disengages from the first limiting hole 25 and the second limiting hole 26, the connecting frame 23 and the filter screen 24 are removed from the collection pool 16. At this time, the connecting frame 23 and the limiting frame 22 are not abut against each other. Thus, the purpose of disassembling the connecting frame 23 and the filter screen 24 is achieved. Therefore, this utility model facilitates the disassembly and cleaning of the filter screen 24, thereby improving the filtering effect of the filter screen 24 on the lubricating oil.

[0044] Working principle:

[0045] The operator installs the first outer shell 1 onto the CNC machine tool, then fixes the workpiece to the top of the rotary table 32, and then starts the servo motor 7 inside the second outer shell 6. The servo motor 7 drives the worm gear 8 to rotate. Since the worm gear 8 meshes with the cam 5, the worm gear 8 also drives the connecting rod 4 to rotate inside the bearing 3 in the mounting hole 2 through the cam 5. When the connecting rod 4 rotates, it drives the rotary table 32 to rotate, thereby adjusting the angle of the workpiece. The operator can then use the CNC machine tool to perform multi-angle processing on the workpiece.

[0046] Workers can start the pump 11 inside the installation slot 9. Under the action of the pump 11, the lubricating oil inside the container 10 will enter the nozzle 13 through the connecting pipe 12, and then be sprayed by the nozzle 13 to the meshing point of the worm 8 and cam 5 to achieve the purpose of lubricating the worm 8 and cam 5.

[0047] Because a receiving plate 15 is provided inside the first outer casing 1, and a collection pool 16 is fixed on the top of the receiving plate 15, the lubricating oil that falls during the lubrication of the worm gear 8 and cam 5 will fall into the collection pool 16, achieving the purpose of lubricating oil recycling. On the one hand, this can prevent lubricating oil from polluting the internal environment of the first outer casing 1, and on the other hand, it can recycle and reuse the lubricating oil, which is relatively energy-saving and environmentally friendly. Because a filter element is provided inside the collection pool 16, which consists of a connecting frame 23 and a filter screen 24, the lubricating oil will pass through the filter screen 24 before falling into the collection pool 16. The filter screen 24 will filter the impurities inside the lubricating oil, improve the purity of the lubricating oil, and improve the efficiency of subsequent lubricating oil recycling and reuse. The operator uses the knob 21 to drive the threaded clamp 20 in the connecting lug. The threaded rod 20 moves within the threaded hole 18 on the outer wall of the first housing 1. After one end of the threaded rod 20 disengages from the hole 19, the receiving plate 15 will not abut against the limiting ear 14. The receiving plate 15 will then be removed from the first housing 1. Subsequently, the telescopic rod 28 and spring 31 are driven to retract on the outer wall of the vertical bar 27. When the telescopic rod 28 retracts, it will drive the connecting plate 29 and the limiting pin 30 to move. After the limiting pin 30 disengages from the first limiting hole 25 and the second limiting hole 26, the connecting frame 23 and the filter screen 24 are removed from the collection pool 16. At this time, the connecting frame 23 and the limiting frame 22 are not abut against each other. Thus, the purpose of disassembling the connecting frame 23 and the filter screen 24 is achieved. Therefore, this utility model facilitates the disassembly and cleaning of the filter screen 24, thereby improving the filtering effect of the filter screen 24 on the lubricating oil.
