Abstract
The invention belongs to the field of assembling and disassembling of an aerospace lens pressing ring, and particularly relates to a fastening and disassembling device for a lens pressing ring. The clamping ring clamping device is used for solving the problems that an ordinary wrench in the prior art cannot meet the size requirements of clamping ring fastening and dismounting, the working effect is not stable enough, and the scratch on the surface of a lens is easily caused. Including twist grip, torsion bar, clamping ring chuck, position sleeve and card, twist grip passes through torsion bar and clamping ring chuck middle part fixed connection, and the position sleeve suit is on the torsion bar and lie in between twist grip and the clamping ring chuck, and the position sleeve inner wall cooperatees with the picture frame outer wall, sets up two draw-in grooves on the clamping ring chuck periphery at least, and the card setting is in the draw-in groove.
Description
Technical Field
The invention belongs to the field of assembling and disassembling of an aerospace lens pressing ring, and particularly relates to a fastening and disassembling device for a lens pressing ring.
Background
At present, the diameter of a lens of the ultra-high precision space lens is large, the size requirements of clamping ring fastening and dismounting cannot be met by a common wrench, meanwhile, the requirement of optical glass on scratch prevention is very high, and in the operation process of clamping ring fastening and dismounting, scratches on the surface of the lens are very easily caused. Although the chinese patent publication No. 203311070U (2013-11-27) solves the problem of adaptation to various sizes in working conditions by using a movable clamp plate, the stable rotation and non-slip in the working process cannot be guaranteed, and the risk of scratching the lens still exists.
Disclosure of Invention
The purpose of the invention is: the utility model provides a fastening and dismounting device for camera lens clamping ring for solve among the prior art ordinary spanner can't satisfy the clamping ring fastening and the size demand of dismantling, the working effect is stable inadequately, and easily causes the problem of lens surface mar.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
a fastening and detaching device for a lens pressing ring is characterized in that: the positioning sleeve is sleeved on the torsion bar and located between the rotation handle and the pressing ring chuck, the inner wall of the positioning sleeve is matched with the outer wall of the glasses frame, at least two clamping grooves are formed in the periphery of the pressing ring chuck, and the clamping pieces are arranged in the clamping grooves.
Further, in order to enable the pressing ring chuck and the mirror frame to be coaxially positioned better, the positioning sleeve is of a bottle cap-shaped structure.
Further, the clamping ring chuck is of a bottle cap-shaped structure.
Furthermore, in order to observe the real-time condition of the card inserted into the clamping groove from the upper part conveniently, a plurality of observation holes are formed in the positioning sleeve and the pressing ring chuck.
Further, the locating sleeve is made of polytetrafluoroethylene.
The invention has the beneficial effects that:
1. due to the good positioning protection effect of the positioning sleeve, the device can stably rotate and does not slide off, and the lens is prevented from being scratched;
2. the clamping ring chuck, the clamping piece and the positioning sleeve can be customized according to the size of the lens, and the lens clamping device has replaceability and is convenient to use.
Drawings
FIG. 1 is an exploded view of the structure of the embodiment;
fig. 2 is a schematic diagram of the working state of the embodiment.
In the figure, 1-a rotary handle, 2-a positioning sleeve, 3-a torsion bar, 4-a clamping ring chuck, 5-a clamping groove, 6-a clamping piece, 7-a clamping ring, 8-a lens, 9-a picture frame, 10-a clamping ring groove and 11-an observation hole.
Detailed Description
The present invention will be described in detail below with reference to specific embodiments and the accompanying drawings.
As shown in fig. 1, the embodiment provides a fastening and detaching device for a lens pressing ring, which includes a rotary handle 1, a torsion bar 3, a pressing ring chuck 4, a positioning sleeve 2 and a clamping piece 6, wherein the rotary handle 1 is fixedly connected with the middle of the pressing ring chuck 4 through the torsion bar 3, the positioning sleeve 2 is sleeved on the torsion bar 3 and is located between the rotary handle 1 and the pressing ring chuck 4, the inner wall of the positioning sleeve 2 is matched with the outer wall of a spectacle frame 9, 8 clamping grooves 5 are arranged on the periphery of the pressing ring chuck 4, and the clamping piece 6 is arranged in the clamping groove 5. In order to better coaxially position the clamping ring chuck 4 and the spectacle frame 9, the positioning sleeve 2 is of a bottle cap-shaped structure, and the inner diameter of the positioning sleeve 2 is larger than the outer diameter of the clamping ring chuck 4. In order to observe the real-time situation of the card 6 inserted into the card slot 5 from the upper part, a plurality of observation holes 11 are respectively arranged on the positioning sleeve 2 and the pressing ring chuck 4. The positioning sleeve 2 is made of polytetrafluoroethylene.
As shown in fig. 2, when the pressing ring is fastened, the pressing ring 7 is placed in the frame 9, the card 6 is inserted into the slot 5, the protruding part of the card 6 is inserted into the groove 10 of the pressing ring, the positioning sleeve 2 is clamped on the outer wall of the frame 9, and the rotating handle 1 is rotated clockwise, so that the pressing ring can be fastened. In the same way, the pressing ring is disassembled anticlockwise.
