Technical Field

[0001] The utility model relates to a fully enclosed precision platform with a small volume and good sealing performance, belonging to the field of precision mechanical equipment. Background Art

[0002] In the precision platforms currently in use, most of their designs are restricted by guide rails and internal components. Therefore, most platforms adopt an open structure. Although this design helps the operation and maintenance of the platform to a certain extent, after long-term use, the open structure of the platform is likely to cause dust accumulation. Due to the dust accumulation, the accuracy of the platform may be affected, and even the platform may malfunction. At the same time, the open design also makes the internal structure of the precision platform vulnerable to damage.

[0003] In addition, traditional precision platforms are also relatively large in volume, require a large use space, and cannot be adapted to some scenarios with relatively compact spaces.

[0004] In view of this, it is indeed necessary to improve the structure of the existing precision platform to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a fully enclosed precision platform with a small volume and good sealing performance.

[0006] To achieve the above purpose, the utility model provides a fully enclosed precision platform, which includes a fixed module and a sliding module.

[0024] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Here, it should be noted that in order to avoid obscuring the present utility model due to unnecessary details, only the structures and / or processing steps closely related to the solution of the present utility model are shown in the drawings, while other details less related to the present utility model are omitted.

[0026] In addition, it should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0027] Please refer to Figures 1 - 5As shown in the figure, a fully enclosed precision platform 100 provided by the present utility model includes a fixed module 110 and a sliding module 120. Among them, the fixed module 110 includes a base 111, and the sliding module 120 includes a top seat 121. The top seat 121 is slidably connected to the base 111, and a sealed space is formed between the top seat 121 and the base 111. On both sides of the base 111 in the sliding direction parallel to the sliding module 120, there are guide rail assemblies 130. The guide rail assemblies 130 are located in the sealed space. The guide rail assemblies 130 include an outer rail 131 and an inner rail 132. The outer rail 131 is fixedly connected to the top seat 121, and the inner rail 132 is fixedly connected to the base 111. A ball device 133 is provided between the outer rail 131 and the inner rail 132, and the outer rail 131 slides relative to the inner rail 132 through the ball device 133.

[0028] The fully enclosed design completely encloses the guide rail assemblies 130 in the sealed space. This design effectively prevents external dust, moisture, impurities, etc. from entering the interior of the fully enclosed precision platform 100, thereby protecting the interior of the fully enclosed precision platform 100 from pollution and damage. This high degree of integration and enclosure improves the overall stability and reliability of the fully enclosed precision platform 100. At the same time, the outer rail 131 and the inner rail 132 are slidably connected through the ball device 133, effectively reducing the volume of the fully enclosed precision platform 100 at the maximum stroke, so that the fully enclosed precision platform 100 always maintains a small volume and adapts to scenarios with higher space requirements.

[0029] The fully enclosed precision platform 100 further includes a motor assembly 140. Both the guide rail assemblies 130 and the motor assembly 140 are located in the sealed space. Key components such as the motor assembly 140 are completely enclosed in the sealed space, which can prevent the motor assembly 140 from being damaged by external dust, moisture, and impurities.

[0030] The motor assembly 140 includes a stator device 141 and a rotor device 142. One of the stator device 141 and the rotor device 142 is fixedly connected to the base 111, and the other of the stator device 141 and the rotor device 142 is fixedly connected to the top seat 121. Since the stator device 141 and the rotor device 142 are respectively fixed on the base 111 and the top seat 121, this stable connection method ensures that the motor assembly 140 can accurately control the sliding position of the top seat 121 during operation. The high-precision characteristics of the motor assembly 140 enable the platform to achieve positioning accuracy at the micron level or even the nanometer level, meeting the requirements of precision machining, detection, and other scenarios.

[0031] In this embodiment, the stator device 141 is fixedly connected to the top seat 121, and the rotor device 142 is fixedly installed on the base 111. By installing the rotor device 142 on the base 111 and the stator device 141 on the top seat 121, the stator device 141 drives the top seat 121 to move relative to the base 111. The stator device 141 has a relatively light mass compared to the rotor device 142. In this way, only a relatively small driving force is required to drive the top seat 121 to move, which is more power-saving and has a faster response speed. At the same time, it also helps to reduce the volume of this fully enclosed precision detection device.

[0032] Further, the guide rail assembly 130 includes an outer rail 131 and an inner rail 132. The outer rail 131 is fixedly connected to the top seat 121, and the inner rail 132 is fixedly connected to the base 111. The outer rail 131 and the inner rail 132 slide relative to each other through balls. The balls roll between the outer rail 131 and the inner rail 132. Compared with sliding friction, the resistance of rolling friction is smaller, thereby reducing energy loss and the generation of frictional heat. At the same time, the wear of the guide rail assembly 130 is mainly concentrated on the balls, and the balls are made of excellent materials and have strong wear resistance. Therefore, the overall wear is small. This design can significantly extend the service life of the guide rail assembly 130 and reduce wear caused by friction. Moreover, the design of the outer rail 131 and the inner rail 132 sliding relative to each other through balls enables the fully enclosed precision platform 100 to have a relatively high movement accuracy, capable of reaching micron-level accuracy, which is particularly important for equipment that requires high-precision positioning.

[0033] Further, the fully enclosed precision platform 100 further includes a detection assembly 150. The detection assembly 150 is located in a sealed space. The detection assembly 150 includes a grating scale 151 and a reading head 152. The reading head 152 is fixedly connected to the base 111, and the grating scale 151 is fixedly connected to the top seat 121. The design of the sealed space effectively prevents impurities such as dust and oil from entering the interior of the detection assembly 150, protecting precision components such as the grating scale 151 and the reading head 152 from contamination, thereby extending the service life. To a certain extent, it reduces the influence of external vibration and impact on the detection assembly 150 and improves the stability and accuracy of measurement.

[0034] The top seat 121 is provided with an abutting portion 122 protruding towards the base 111. The base 111 is provided with a limiting block 112. The limiting block 112 is located at both ends of the sliding direction of the sliding module 120. The abutting portion 122 moves within the range of the limiting block 112 to limit the sliding distance of the top seat 121 relative to the base 111.

[0035] By providing a limit block 112 on the base 111 and designing a contact portion 122 protruding towards the base 111 on the top seat 121, the sliding distance of the top seat 121 relative to the base 111 can be accurately limited. This design ensures that the top seat 121 does not exceed the predetermined range during the sliding process, thereby improving the accuracy and reliability of the device. Compared with other complex limit mechanisms, such as electronic sensors, hydraulic or pneumatic devices, etc., this mechanical limit design is simpler, more direct and less costly. It does not require additional energy supply or complex control systems, reducing the complexity and maintenance cost of the device.

[0036] At both ends in the sliding direction of the sliding module 120, there are a top seat baffle 123 and a base baffle 113. The top seat baffle 123 is fixedly connected to the top seat 121, the base baffle 113 is fixedly connected to the base 111, and the top seat baffle 123 is engaged with the base baffle 113. The engagement of the top seat baffle 123 and the base baffle 113 can effectively prevent external dust and dirt from entering the enclosed space between the base 111 and the top seat 121, effectively protecting the internal components.

[0037] There is a wire outlet on the base baffle 113 at one end. The fully enclosed precision platform 100 further includes a cable 161, and the cable 161 extends outwards from the wire outlet. There is a wire outlet module 160 in the base 111. The wire outlet module 160 is arranged close to the wire outlet, and the wire outlet module 160 is covered with a wire outlet plate. The design of the wire outlet allows the cable 161 to extend out of the wire outlet module 160 inside the platform in an orderly manner, avoiding the situation where the cable 161 is randomly scattered or cross-wound outside the platform, thus maintaining the cleanliness and beauty of the platform. In addition, when it is necessary to repair or replace the cable 161, the operator can conveniently operate through the wire outlet without disassembling the platform or moving other components, improving the maintenance efficiency. The wire outlet plate in the wire outlet module 160 provides additional protection for the cable 161, preventing physical damage such as extrusion, abrasion or pulling of the cable 161 inside the platform.

[0038] On both sides of the base 111 and both sides of the top base 121, there are connection holes 170 arranged closely along the sliding direction of the sliding module 120. Corresponding connection holes 170 are provided on the inner rail 132 and the outer rail 131. Fasteners are passed through the connection holes 170 on the base 111 and the inner rail 132 to fixedly connect the inner rail 132 and the base 111. Fasteners are passed through the connection holes 170 on the top base 121 and the outer rail 131 to fixedly connect the outer rail 131 and the top base 121. Through the combined use of multiple connection holes 170 and fasteners, it can ensure that the connection between the inner rail 132 and the base 111, and the outer rail 131 and the top base 121 is more firm and stable. This multi-point fixing method can effectively disperse the force, reduce deformation or damage caused by excessive single-point force, thereby improving the overall stability of the entire sliding module 120 and the guide rail assembly 130. At the same time, this design method enables the guide rail assembly 130 to be flexibly configured according to different application requirements. By adjusting the position and number of the connection holes 170, the guide rail assembly 130 with different lengths, widths, and load requirements can be adapted, improving the versatility and adaptability of the fully enclosed precision platform 100.

[0039] In summary, for the fully enclosed precision platform 100, through the fully enclosed design, the guide rail assembly 130 is completely enclosed in a sealed space. This design effectively prevents external dust, moisture, impurities, etc. from entering the interior of the fully enclosed precision platform 100, thereby protecting the interior of the fully enclosed precision platform 100 from pollution and damage. At the same time, the outer rail 131 and the inner rail 132 are slidably connected through the ball device 133, so that when at the maximum stroke, the fully enclosed precision platform 100 can still maintain a small volume and adapt to scenarios with higher space requirements.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
