Abstract
The utility model discloses a double-stage leveling device which comprises the following components: a lower iron wedge block (1), an upper iron wedge block (2) and a coarse adjusting screw (5). The double-stage leveling device furthermore comprises a switching block (6), a large-displacement adjusting bolt (3) and a fine adjusting screw (4). The lower iron wedge block (1) is placed on a mounting bottom surface. The coarse adjusting screw (5) is placed in a transverse screwed hole of the upper iron wedge block (2). The large-displacement adjusting bolt (3) is placed in a vertical screwed hole of the upper iron wedge block (2). The switching block (6) is placed at the top part of the large-displacement adjusting bolt (3). The fine adjusting screw (4) is placed in a screwed hole of the switching block (6) and is in pressure joint with the head of the large-displacement adjusting bolt (3). Preliminary leveling is obtained through matching between the lower iron wedge block (1) and the upper iron wedge block (2). The fine adjusting screw (4) is adjusted so the switching block (6) adjusts the displacement continuously, thereby obtaining accurate leveling. The double-stage leveling device has the following advantages: concise structure, and high efficiency.
Description
Technical field
The utility model relates to a kind of levelling device, particularly a kind of twin-stage levelling device.
Background technology
In the emission process of guided missile or shell, the system accuracy of early takeoff has considerable influence to the emission hit rate, so emission system all needs leveling to guarantee the initial transmissions precision of system.The useful Wedge device leveling of manual leveling mode commonly used perhaps directly turns leveling at emission system installed surface thread mill drilling up and down with screw.The wedge levelling device mainly is made up of last wedge piece, declivity iron block, coarse adjustment bolt; Wedge leveling mode is to make up and down two wedge mating surfaces produce displacement to reach the leveling purpose through laterally turning the coarse adjustment bolt; Open the screwed hole mode and be through holding out against and the bottom surface is installed turns screwed hole up and down and produce displacement and reach the leveling purpose with screw; But there is following shortcoming in this dual mode: hang down simultaneously owing to be laterally to turn bolt with Wedge device leveling precision, the operation effort is time-consuming, and efficient is lower; It is hard to necessarily require to install the bottom surface with stubborn bolt mode, can bear the screw pressure, owing to be on installed surface, to open screwed hole, the displacement that can produce is less, so levelling range is limited simultaneously.
The utility model content
The purpose of the utility model is to provide a kind of twin-stage levelling device, solves lower, the levelling range finiteness problem of levelling device efficient at present commonly used.
A kind of twin-stage levelling device comprises: declivity iron block, last wedge piece, coarse adjustment screw also comprise: bolt and fine adjustment screw are regulated in switching piece, big displacement.The declivity iron block places installation system that the bottom surface is installed; Last wedge piece places declivity iron block top, combines closely in two inclined-planes, and the coarse adjustment screw places the horizontal screwed hole of wedge piece; Big displacement is regulated bolt and is placed the vertical screwed hole of wedge piece; The switching piece places big displacement to regulate the bolt top, and fine adjustment screw places switching piece screwed hole and regulates the bolt head crimping with big displacement, needs the load equipment of leveling to place switching piece top.
Regulate the coarse adjustment screw, the contact-making surface of last wedge piece, declivity iron block produces displacement, reaches the purpose of preliminary leveling.Regulate fine adjustment screw, fine adjustment screw has withstood big displacement and has regulated bolt, and the switching piece produces upper and lower displacement, needs the load equipment of leveling and switching piece to move up and down simultaneously, thereby reaches the purpose of leveling.If load equipment installation environment bottom surface is soft or the gradient is arranged, regulate big displacement and regulate bolt, reach basic horizontal, again through the twin-stage leveling, realize the leveling purpose.
Can succinctly efficiently carry out system's leveling through twin-stage leveling mode, especially the bottom surface is installed and be in the soft and uneven environment, use big displacement bolt to regulate and replenish the displacement drop, can carry out leveling to system effectively fast at equipment.
Description of drawings
A kind of twin-stage levelling device of Fig. 1.
1. bolt 4. fine adjustment screws 5. coarse adjustment screws 6. switching pieces are regulated in the 3. big displacements of wedge piece on the declivity iron block 2..
The specific embodiment
A kind of twin-stage levelling device comprises: declivity iron block 1, last wedge piece 2, coarse adjustment screw 5 also comprise: bolt 3 and fine adjustment screw 4 are regulated in switching piece 6, big displacement.Declivity iron block 1 places installation system that the bottom surface is installed; Last wedge piece 2 places declivity iron block 1 top, and two inclined-planes closely paste mutually, and coarse adjustment screw 5 places wedge piece 2 horizontal screwed holes; Big displacement is regulated bolt 3 and is placed wedge piece 2 vertical screwed holes; Switching piece 6 places big displacement to regulate bolt 3 tops, and fine adjustment screw 4 places switching piece 6 screwed holes and regulates bolt 3 head crimping with big displacement, needs the load equipment of leveling to place switching piece 6 tops.
Be screwed into the coarse adjustment screw 5 of italic piece 2 through adjusting, the inclined-plane of wedge piece 2, declivity iron block 1 cooperated produce displacement, reach the purpose of preliminary leveling.Through twisting fine adjustment screw 4, fine adjustment screw 4 has withstood big displacement and has regulated bolt 3, and switching piece 6 produces upper and lower displacement, needs the load equipment of leveling and switching piece 6 to move up and down simultaneously, thereby reaches the purpose of leveling.If load equipment installation environment bottom surface is soft or the gradient is arranged, can regulate big displacement and regulate bolt 3, reach basic horizontal, again through the twin-stage leveling, realize the leveling purpose.
