Background technique
Electro-optic theodolite is the important measuring equipment in guided missile, aerospace measurement control system, and its horizontal axis General Requirements rotates within the scope of-8 ° ~ 185 °, so need to install the motion of corresponding position-limit mechanism restrictive axes system and shaft plays buffer function.Traditional position-limit mechanism adopts cylindrically coiled spring as shock absorber, by the kinetic energy of spring-compressed absorption axes system.Due to the restriction of physical dimension, spring diameter is smaller, absorbs finite energy, even occurs the situation of rigid collision, cause the damage of set screw, cause position-limit mechanism to lose efficacy, have impact on the use of electro-optic theodolite, reduce equipment reliability.On the other hand, position-limited lever in conventional construction and position limit socket adopt small―gap suture to coordinate, because position-limited lever Impact direction is not along its axis of movement, but have a little angle, there is radial component, thus cause frictional force greatly to increase, position-limited lever motion inconvenience, and easily scratch the fitting surface of itself and position limit socket, shorten working life.
Summary of the invention
The object of this invention is to provide a kind of floating type electro-optic theodolite position-limit mechanism based on disc spring, solve the technical problem that Conventional limit mechanism reliability is poor, working life is short.
Technical solution of the present invention is: the position-limit mechanism provided comprises position limit socket and position-limited lever, and its special way is: described position limit socket comprises top board, intermediate clapboard and base plate; Top board and intermediate clapboard are provided with central through bore, for mounting limit bar; Be provided with baffle plate in the middle part of described position-limited lever, between baffle plate lower end surface and intermediate clapboard upper-end surface, combination disk spring be installed; Position-limited lever bottom is through the lower end surface of stretching out intermediate clapboard after the center hole of combination disk spring; Position-limited lever top extend out to position limit socket outside through after upper cover plate.Combination disk spring is made up of involutory the stacking of multiple disc spring sheets, can the kinetic energy of abundant absorption axes system, ensure that the reliability of position-limit mechanism.
The distance of above-mentioned position-limited lever bottom and base plate upper-end surface is greater than the limited compression amount of combination disk spring, can prevent from, between position-limited lever and base plate, rigid collision occurs.
The upper-end surface of above-mentioned top board is provided with spherical groove; Spherical groove is provided with sphere slide block adaptive with it; The central through bore of sphere slide block is passed on the top of described position-limited lever, and sphere slide block can be driven to slide in spherical groove.Directly not contacting between position-limited lever with top board, because this reducing frictional loss, improve the working life of position-limit mechanism.
The upper-end surface of above-mentioned top board is provided with anti-drop device, for limiting the range of movement of sphere slide block, and prevents sphere slide block from deviating from.
Above-mentioned position-limited lever top is provided with protecting jacket, between theodolite horizontal axis and position-limited lever, rigid collision occurs for preventing.
The upper-end surface of base plate is provided with buffer stopper, and buffer stopper is positioned at below position-limited lever, for preventing position-limited lever bottom and base plate generation rigid collision.
Above-mentioned protecting jacket and buffer stopper are quality of rubber materials, protection and good buffer effect.
Beneficial effect of the present invention is:
(1) the present invention adopts combination disk spring structure, and absorbing power is strong, and compact structure is easy for installation, avoids rigid collision, improves system reliability.
(2) the present invention uses the composite structure of spherical groove and sphere slide block to reduce the non-contact of position-limited lever and position limit socket, reduce processing and assembling requirement, motion flexibility and reliability, decreases the frictional loss between position-limited lever and position limit socket, improves the working life of position-limit mechanism.
(3) the present invention by installing protecting jacket and buffer stopper respectively on position-limited lever and position limit socket, reduce further the risk of rigid collision.
