Detailed Description

The following describes in further detail specific embodiments of the present invention based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

Please refer to fig. 1, which is a schematic structural diagram of a usage status of a fine adjustment device according to the present invention. The fine-tuning device is used for fine-tuning the connection between the first table top 11 and the second table top 12 so as to avoid point contact or line contact when the first table top 11 is in direct contact with the second table top 12. Please refer to fig. 2, which is a schematic structural diagram of the present invention. The fine adjustment device comprises a base 21 placed on the first table 11, a plane mechanism 22 arranged on the base 21, and a universal mechanism 23 arranged on the plane mechanism 22. It is contemplated that the fine tuning device may also include other functional modules, such as mounting components, connecting components, etc., which are well known to those skilled in the art and will not be described herein.

The base 21 includes a base 211, a cover 212 fixed to the base 211, and a receiving chamber 213 formed between the base 211 and the cover 212. The cover plate 212 defines an opening 214 for mounting the gimbal mechanism 23. The base 211 and the cover 212 may be connected by a fastener such as a bolt or a stud. The base 211 and the cover plate 212 should have a certain structural strength, and the base 211 should further be provided with a plurality of connection holes (not shown), and the connection holes are fixedly connected to the second table top 12 through bolts. The receiving cavity 213 is opened in the middle of the base 211 and the cover 212, and specifically, the receiving cavity 213 can be formed by forming a circular groove on each of the base 211 and the cover 212 and then combining the base 211 and the cover 212 together. It is contemplated that the receiving cavity 213 may be formed only on the base 211 or only on the cover 212. . The receiving cavity 213 is cylindrical, and the diameter of the opening 214 is smaller than that of the receiving cavity 213 so as to prevent the planar mechanism 22 from sliding out of the opening 214 and falling off.

The planar mechanism 22 may be a planar bearing disposed in the receiving cavity 213. The flat bearings are primarily subjected to axial loads, which are well known to those skilled in the art and therefore will not be described in detail herein. In the present embodiment, the position of the planar mechanism 22 is defined by the shape of the accommodating chamber 213.

The universal mechanism 23 includes a base plate 231 disposed on the planar mechanism 22, a universal joint 232 fixed on the base plate 231 and passing through the opening 214, and a connecting base 233 rotatably connected to the universal joint 232. The base plate 231 and the universal joint 232 are screwed and interposed between the planar mechanism 22 and the cover plate 212, so that the relative position of the base plate 231 and thus the relative position of the universal mechanism 23 are fixed. The gimbal 232 includes a ball 2321 capable of universally sliding, and a supporting post 2322 connected to the ball 2321 and disposed on the base 231. The support post 2333 may be fixedly attached to the base plate 231 by screws. The ball head 2321 may have a specific structure according to actual needs, in this embodiment, the ball head 2321 is a cylindrical structure with two spherical crowns cut off, one end of the cylindrical structure is connected with the supporting column 2322, and the other end of the cylindrical structure is inserted into the connecting seat 233.

The connecting seat 233 includes a first through-slot 2331, a second through-slot 2332 communicating with the first through-slot 2331 and receiving the ball-head 2321, an abutting ring 2337 abutting against the ball-head 2321, and a snap spring 2338 for fixing a positional relationship between the gimbal 232 and the abutting ring 2337.

The second through-slot 2332 is disposed close to the base 21, and the aperture of the second through-slot 2332 is larger than the aperture of the first through-slot 2331 to facilitate the installation of the gimbal 232 in the first and second through-slots 2331, 2332. The inner wall of the first through-groove 2331 is provided with an arc surface 2336 matched with the lateral arc surface of the ball head 2321. An arc surface 2336 matching the lateral arc of the ball head 2321 facilitates the rotation of the ball head 2321. The abutting ring 2337 is used to be clamped on the ball head 2321 together with the second through-groove 2332 so as to fix the relative position between the ball head 2331 and the abutting ring 2337 and the second through-groove 2332 under the action of the clamp spring 2338. Also, therefore, the minimum inner diameter of the abutment ring 2337 is less than the maximum diameter of the ball 2331. In order to fix the snap ring 2337, a snap ring 2339 is formed in the inner wall of the second through-hole 2332 at a side of the snap ring 2337 facing the substrate 231. The clamp spring 2338 is clamped in the clamp spring groove 2339 to prevent the ball 2321 from being separated from the connecting seat 233. It is contemplated that the latch spring 2339 is an annular groove. The included angle between the top surface of the connecting seat 233 and the horizontal plane is specifically defined by the ball head 2321 and the structures of the first and second through grooves 2331, 2332, which can be any reasonable angle value. In the present embodiment, the angle is 25 degrees at the maximum.

It should be further noted that, in the present embodiment, the first table 11 may be fixedly connected to the connecting seat 233 or directly placed on the connecting seat 233, and the second table 12 is fixedly connected to the base 211, so that the connection between the first table 11 and the connecting seat 233 is a surface connection, and the connection between the second table 12 and the base 211 is also a surface connection. Even if the first table top 11 or the second table top 12 is not parallel to the horizontal plane, the gimbal 232 can rotate in the first and second through-slots 2331, 2332 and the abutting ring 2237 to achieve fine adjustment of the positional relationship between the first table top 11 and the second table top 12, thereby effectively avoiding point contact or line contact between the first and

second table tops

11, 12 due to direct contact.

Compared with the prior art, the utility model discloses a micromatic setting can turn into the point contact that the direct contact of first mesa 11 and second mesa 12 caused easily into the face contact, and the effectual wearing and tearing that have reduced between first,

second mesa

11, 12 have promoted the security, have prolonged life, and make first,

second mesa

11, 12 independent motion separately through planar mechanism, and application scope is wide.
