Description

Technical Field

[0001] This utility model relates to the field of precision turntable technology, specifically a precision turntable with a low coefficient of friction. Background Technology

[0002] As the name suggests, a precision rotary table can perform rotary motion and output a certain torque to achieve high-precision positioning. Precision rotary tables have a wide range of applications, such as high-precision measurement, optical inspection and manufacturing, and nanotechnology. They are widely used in machining centers and CNC grinding machines. Low-friction precision rotary tables are high-precision, low-friction-resistance rotary work platforms, widely used in fields requiring precise positioning, stable rotation, or high dynamic response. Their core design goal is to minimize frictional interference, ensuring smooth and accurate motion while maintaining high rigidity and stability.

[0003] In existing precision turntables, the turntable rotates above the rotating base, and there is a gap between the turntable and the rotating base. During use, dust and particulate matter can easily enter the gap, which increases the coefficient of friction of the turntable. At the same time, dust and particulate matter entering from the gap can easily cause wear on the internal parts of the turntable, affecting the precision of the turntable.

[0004] Based on this, a low-friction coefficient precision turntable is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0027] 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 the accompanying drawings and embodiments.

[0028] In one embodiment, such as Figure 1 - Figure 4 As shown, a precision turntable with a low coefficient of friction includes a turntable body 1, a rotating disk 11 is provided on the top of the turntable body 1, four insertion blocks 12 are installed around the rotating disk 11, and a strong magnetic block 13 is installed inside the insertion block 12.

[0029] The outer side of the insertion block 12 is fitted with a connecting component, which includes a connecting ring 2. The connecting ring 2 has four connecting slots 21 on its inner periphery. A top ring 22 is installed on the top of the connecting ring 2. A silicone ring 23 is installed on the inner bottom of the top ring 22. A first Velcro 24 is installed on the bottom of the connecting ring 2.

[0030] The bottom of the first Velcro 24 is fitted with a dustproof component;

[0031] An air extraction assembly is installed on one side of the turntable body 1.

[0032] In this embodiment, the connecting component is quickly installed by the interlocking connection between the insert block 12 and the connecting ring 2, and the connecting component is fixed by the magnetic attraction between the strong magnetic block 13 and the top ring 22. The dustproof component is installed by attaching the first Velcro 24 at the bottom of the connecting ring 2 to the dustproof component, and the air extraction component sends air into the air outlet component.

[0033] In one embodiment, such as Figure 1 and Figure 2As shown, four bases 14 are installed around the bottom of the turntable body 1. A drive motor 15 is provided on one side of the turntable body 1. The turntable body 1 is driven by the drive motor 15. The operation of the drive motor 15 drives the turntable body 1 to move, thereby causing the rotating disk 11 on the top of the turntable body 1 to rotate.

[0034] In one embodiment, such as Figure 1 and Figure 3 As shown, the top ring 22 is annular and made of iron. The top ring 22 is attracted and connected to the strong magnetic block 13 through the iron material of the top ring 22.

[0035] In one embodiment, such as Figure 1 and Figure 3 As shown, the dustproof component includes a second Velcro 25, which is attached to the bottom of the first Velcro 24. A brush 26 is installed on the bottom of the second Velcro 25 to cover the gaps and prevent dust from entering the gaps.

[0036] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the air extraction assembly includes an air pump 3, which is installed on one side of the turntable body 1. An air outlet pipe 31 is installed at the air outlet end of the air pump 3, and a diverter block 32 is installed on one side of the air outlet pipe 31. Air is drawn in by the operation of the air pump 3 and then sent to the diverter block 32 through the air outlet pipe 31.

[0037] In one embodiment, such as Figure 1 and Figure 4 As shown, air outlet components are installed around the diversion block 32 to send out air, thereby cleaning the dustproof components.

[0038] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the air outlet assembly includes a conveying pipe 33, which is installed around the flow divider block 32. An air outlet ring 34 is installed on one side of the conveying pipe 33 and is installed on the top of the turntable body 1. Air outlet holes 36 are opened around the air outlet ring 34, and a silicone layer 35 is installed inside the air outlet holes 36. After the air is diverted by the flow divider block 32, it is sent into the four conveying pipes 33. The air is sent out from the air outlet ring 34 through the conveying pipes 33. The silicone layer 35 avoids the problem of blockage of the air outlet holes 36.

[0039] In one embodiment, such as Figure 1 and Figure 4As shown, the silicone layer 35 is in the shape of a square and is made of silicone rubber. The material of the silicone layer 35 allows the pore size to be enlarged by deformation when dust clogs the pores, thus achieving an anti-clogging effect.

[0040] The above embodiment discloses a low-friction coefficient precision turntable. The connecting ring 2 is installed by fitting the connecting groove 21 inside the connecting ring 2 and the insertion blocks 12 around the rotating disk 11. The connecting assembly is fixed by the attraction between the top ring 22 of the connecting ring 2 and the strong magnetic block 13 in the insertion block 12, preventing detachment during use and improving the convenience of the device. The silicone ring 23 on the bottom inner side of the top ring 22 adheres to the top of the rotating disk 11, achieving a sealing effect and preventing dust and particulate matter from entering. Magnetic and sliding connections facilitate quick installation and disassembly of the connecting assembly. The dustproof assembly is installed by attaching the first Velcro 24 and the second Velcro 25, while also facilitating easy installation and disassembly. The dustproof components are disassembled and replaced. The gaps are blocked by the brush 26 to prevent dust from entering the gaps between the rotating disk 11 and the turntable body 1, which would cause the friction coefficient of the device to increase and the accuracy to decrease. The operation of the air pump 3 draws in outside air and sends it to the diverter block 32 through the air outlet pipe 31. The diverter block 32 distributes the air into the interior of the four conveying pipes 33. The air is then sent to the air outlet ring 34 through the conveying pipes 33 and finally sprayed out through the air outlet 36, thereby cleaning the brush 26 and preventing dust from accumulating and entering the gaps, thus improving the practicality of the device. When the air outlet 36 is blocked, the deformation of the silicone layer 35 enlarges the aperture to facilitate cleaning of the air outlet 36, thus improving the convenience of the device.

[0041] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
