Abstract
The utility model relates to instrument manufacturing technical field, particularly relates to a kind of lever adjusting device.Comprise spiral micrometer head, lever, extension spring, turning axle and wire rope, the end thereof contacts of described spiral micrometer head and described lever, the middle part of described lever is connected with described extension spring, the other end and the described turning axle of described lever are slidably connected, and described wire rope is fixed on described lever by turning axle.The utility model simplicity of design, compact conformation, this device forms according to lever principle research and development, by lever segment, adjustment portion, back shaft part, extension spring part, the part such as wire rope composition, wherein lever segment, adjustment portion, back shaft part, extension spring part constitutes the main part of lever regulate, adding of wire rope, mainly play and regulate other to need the device regulated by the adjustment of lever, due to the flexibility of wire rope, rigidity, the feature such as linear, make lever more accurate in application process, convenient, usable range is more extensive.
Description
Technical field
The utility model relates to instrument manufacturing technical field, particularly relates to a kind of lever adjusting device.
Background technology
Lever is called under force around the strong of point of fixity rotation.In life as required, lever can be made straight, also can do embayment, but must be hard object.Almost all can't do without lever in each machine, lever regulating engagement positions, be obtained for and apply widely in current every field, the application in exact instrument accounts for proportion is also increasing gradually.The application of traditional sense upper lever in instrument, be come with the point-to-point hard contact of required connection adjust structure mostly, such Long-Time Service, will certainly cause the wearing and tearing of contact point, affects the precision of instrument.
Utility model content
The purpose of this utility model is the deficiency overcoming above-mentioned technology, and provides a kind of lever adjusting device, improves measuring accuracy.
The utility model for achieving the above object, by the following technical solutions: a kind of lever adjusting device, comprise spiral micrometer head, lever, extension spring, turning axle and wire rope, the end thereof contacts of described spiral micrometer head and described lever, the middle part of described lever is connected with described extension spring, the other end and the described turning axle of described lever are slidably connected, and described wire rope is fixed on described lever by turning axle.
Preferably, described wire rope is fixed on described lever by set nut.
The beneficial effects of the utility model are: the utility model simplicity of design, compact conformation, this device forms according to lever principle research and development, by lever segment, adjustment portion, back shaft part, extension spring part, the part such as wire rope composition, wherein lever segment, adjustment portion, back shaft part, extension spring part constitutes the main part of lever regulate, adding of wire rope, mainly play and regulate other to need the device regulated by the adjustment of lever, due to the flexibility of wire rope, rigidity, the feature such as linear, make lever more accurate in application process, convenient, usable range is more extensive.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, spiral micrometer head; 2, lever; 3, extension spring; 4, turning axle; 5, wire rope.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing and preferred embodiment, as shown in Figure 1, a kind of lever adjusting device, comprise spiral micrometer head 1, lever 2, extension spring 3, turning axle 4 and wire rope 5, the end thereof contacts of described spiral micrometer head and described lever, the middle part of described lever is connected with described extension spring, and the other end and the described turning axle of described lever are slidably connected, and described wire rope is fixed on described lever by turning axle.Described wire rope is fixed on described lever by set nut.Using spiral micrometer head 1 as the adjustment portion of this device, mainly play regulating device displacement and digital independent function; By the adjustment of micrometer head, drive lever 2 to rotate, one end and the turning axle 4 of lever are slidably connected, and lever is with the axle core of turning axle 4 for axle rotates, and wherein, extension spring 3 can be that reference position got back to by lever, and wire rope 5, by turning axle 4, is fixed on lever.The rotation of lever, has driven the change of wire rope 5 relative position, thus drives the variation of the relative position of other web members, plays the effect of lever regulate.
The utility model simplicity of design, compact conformation, this device forms according to lever principle research and development, by lever segment, adjustment portion, back shaft part, extension spring part, the part such as wire rope composition, wherein lever segment, adjustment portion, back shaft part, extension spring part constitutes the main part of lever regulate, adding of wire rope, mainly play and regulate other to need the device regulated by the adjustment of lever, due to the flexibility of wire rope, rigidity, the feature such as linear, make lever more accurate in application process, convenient, usable range is more extensive.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
