Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC rotary table technology, specifically a CNC rotary table for arc surface cam grinding. Background Technology
[0002] Currently used CNC rotary tables are equipped with lubrication mechanisms to reduce friction and wear during operation. By replenishing oil, a lubricating film is formed between the friction surfaces of the machines, reducing friction and making the equipment run more smoothly.
[0003] In order to improve the utilization rate of lubricating oil, any lubricating oil that falls into the machine will be collected. However, this also leads to the collection of debris generated by mechanical wear, which is mixed with the lubricating oil. As a result, when the machine is recycled, it actually affects the lubrication effect and the life of the machine. Utility Model Content
[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0005] Therefore, the technical solution adopted by this utility model is as follows:
[0006] A CNC rotary table for arc-shaped cam grinding includes a rotary table mechanism, a drive mechanism, and a lubrication mechanism. The rotary table mechanism includes a housing and a turntable movably embedded in the top of the housing. The drive mechanism includes a worm gear connected to the bottom of the turntable, a worm meshing with one side of the worm gear, and a motor connected between the housing and the worm gear. The worm gear is movably connected to the bottom of the inner cavity of the housing. The lubrication mechanism includes an annular shell and a box body fixed to the bottom of the inner cavity of the housing, an oil pump installed inside the box body, an oil pipe connected to the water outlet of the oil pump, and multiple oil drip holes opened at the bottom of the oil pipe. The annular shell is movably sleeved on the bottom of the worm gear, and the box body communicates with the interior of the annular shell.
[0007] By adopting the above technical solution, the oil pump is started, and then the lubricating oil in the housing enters the oil pipe and then flows out through multiple oil drip holes. The lubricating oil drips at the meshing position of the worm gear and worm, so that both can be fully coated with lubricating oil. When the lubricating oil and sludge falling from the worm gear and worm fall, they are attracted by the magnet, preventing the sludge from flowing. This ensures that the oil pump can only draw clean lubricating oil, improving the lubrication effect and mechanical life.
[0008] In a preferred embodiment, the present invention may be further configured such that: a magnet is installed inside the annular shell, the magnet extends into the interior of the box, and the top is set as a slope.
[0009] In a preferred embodiment, the present invention can be further configured such that the diameter of the annular shell is larger than the diameter of the worm gear, and the two are vertically coaxial.
[0010] In a preferred embodiment, the present invention can be further configured such that the oil pipe is U-shaped and the water outlet end of the oil pipe is connected to the inside of the box.
[0011] In a preferred embodiment, the present invention can be further configured such that the oil pipe is located at the bottom of the turntable and is sleeved at the top of the meshing point between the worm gear and the worm.
[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0013] In this invention, the oil pump is started, and then the lubricating oil in the housing enters the oil pipe and then flows out through multiple drip holes. The lubricating oil drips at the meshing position of the worm gear and worm, so that both can be fully coated with lubricating oil. When the lubricating oil and sludge falling from the worm gear and worm fall, they are attracted by the magnet, preventing the sludge from flowing. This ensures that the oil pump can only draw clean lubricating oil, improving the lubrication effect and mechanical life. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0026] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0027] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a CNC rotary table for arc-shaped cam grinding.
[0028] Example 1:
[0029] Combination Figure 1-6 As shown, the present invention provides a CNC rotary table for arc surface cam grinding, including a rotary table mechanism 100, a drive mechanism 200 and a lubrication mechanism 300. The rotary table mechanism 100 includes a housing 110 and a turntable 120 movably embedded in the top of the housing 110.
[0030] The drive mechanism 200 includes a worm gear 210 connected to the bottom of the turntable 120, a worm 220 meshing with one side of the worm gear 210, and a motor 230 connected between the housing 110 and the worm 220. The worm gear 210 is movably connected to the bottom of the inner cavity of the housing 110.
[0031] The lubrication mechanism 300 includes an annular shell 310 and a box body 320 fixedly connected to the bottom of the inner cavity of the housing 110, an oil pump 330 installed inside the box body 320, an oil pipe 340 connected to the water outlet of the oil pump 330, and a plurality of oil drip holes 350 opened at the bottom of the oil pipe 340. The annular shell 310 is movably sleeved on the bottom of the worm gear 210, and the box body 320 communicates with the interior of the annular shell 310.
[0032] Furthermore, the oil pipe 340 is configured in a "U" shape, and the water outlet end of the oil pipe 340 is connected to the inside of the box 320. This shape design allows the oil pipe 340 to accurately drip oil onto the outside of the worm gear 210 and the worm 220.
[0033] Furthermore, the oil pipe 340 is located at the bottom of the turntable 120 and is sleeved at the top of the meshing point between the worm gear 210 and the worm 220. The position of the oil pipe 340 allows the lubricating oil to lubricate both the worm gear 210 and the worm 220 simultaneously, thereby improving the lubricating oil's performance.
[0034] Example 2:
[0035] Combination Figure 2 and Figure 5As shown, based on Embodiment 1, a magnet 400 is installed inside the annular shell 310. The magnet 400 extends into the box body 320 and has a sloping top. The magnet 400 can attract and hold the sludge in the lubricating oil, so that the recovered lubricating oil can be safely reused.
[0036] Example 3:
[0037] Combination Figure 2 and Figure 5 As shown, in the above embodiment, the diameter of the annular shell 310 is larger than the diameter of the worm gear 210, and the two are vertically coaxial. The diameter design of the annular shell 310 allows all the lubricating oil flowing down from the worm gear 210 to enter the interior of the annular shell 310.
[0038] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the motor 230 is started, and then the worm 220 drives the worm wheel 210 to rotate. During this process, the oil pump 330 is started, and then the lubricating oil in the housing 320 enters the oil pipe 340 and then flows out through multiple oil drip holes 350. The lubricating oil drips at the meshing position of the worm wheel 210 and the worm 220, so that both can be fully coated with lubricating oil. When the lubricating oil and sludge falling from the worm wheel 210 and the worm 220 fall, they are attracted by the magnet 400 to prevent the sludge from flowing, so that the oil pump 330 can only draw clean lubricating oil, thereby improving the lubrication effect and mechanical life.
[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
