Abstract
The utility model discloses a novel mechanical member matched with a digital display measuring meter. The utility model is composed of a casing body, a measuring rod, an upper and a lower supporting sleeves, a main grid supporting seat and a back cover, a guide mechanism of the utility model is composed an adjusting screw nail on the main grid supporting seat, a steel ball and a guide block of the back cover component, the parallelism of the guide mechanism and the axial cord of the measuring rod is adjustable, a dynamometer spring is directly installed on the measuring rod, and the guide surface of the guide block is sprayed with polytetrafluoroethylene. The novel mechanical member has the advantages of simple structure, high running precision and long service life.
Description
The utility model relates to a kind of and the matching used special-purpose machinery member of digital display scale.
The digital display scale is the electronic type liquid crystal display measurer that is used to replace mechanical formula weight table (as clock gauge).Present being seen apparent scale mechanical component is continued to use the structure of mechanical scale, and its guiding mechanism adopts independently slide rail and guide rod structure, separates with the main grid supporting base, and dynamometer spring is installed between supporting base and the housing, and machinery is complicated, and processing technology is poor.
The purpose of this utility model provides and a kind ofly can overcome the prior art weak point, have simple in structure, precision is high, long service life with the matching used mechanical component of digital display scale.
The utility model is achieved in that the supporting mechanical component of digital display scale comprises measuring staff, housing, main grid supporting base and front and rear covers, be characterized in supporting base, the left and right adjusting screw, steel ball and rear case component are formed the guiding mechanism that flatness is adjustable, measuring staff passes the housing two ends, center fixed has the main grid supporting base, have two holes on the supporting base, load onto set screw and steel ball in the hole, digital display sensor main grid is installed on the supporting base, dynamometer spring also is housed on the measuring staff, its two is separately fixed at measuring staff and up and down in the hole of supporting sleeve, rear case component is composited by rear cover body and orienting lug, orienting lug is embedded in the rear cover body, for the life-span is increased, the spigot surface of orienting lug is sprayed teflon, and forms the high-quality fastness with the steel ball that hardens.
The utility model has the advantages that:
1. because guiding mechanism is formed a guiding mechanism that flatness is adjustable by main grid supporting base, set screw, steel ball and rear case component, the guiding mechanism of scale and scale housing, main grid supporting base are integrated, have simplified mechanism, guaranteed precision.
2. the poly-second fluorothene of the spigot surface of orienting lug spraying is formed a high-quality, durable fastness with the steel ball that hardens, and has increased the serviceable life of scale mechanical parts.
3. dynamometer spring is installed on the measuring staff, has simplified scale construction.
4. scale is by measuring staff, basic parts such as supporting sleeve, main grid supporting base, rear case component are formed up and down, and the housing profile changes can not influence the kinematic accuracy of scale and the structure of basic part, and scale can conveniently change external form.
Below in conjunction with accompanying drawing enforcement structure of the present utility model is described:
Fig. 1 is and the matching used mechanical component cut-open view of digital display scale;
Fig. 2 is the A-A partial sectional view of Fig. 1.
See from figure: guiding mechanism is by housing 2, measuring staff 1, rear case component 3 and 4, main grid supporting base 5 is formed, the axis keeping parallelism of 2 liang of planes of housing and measuring staff support holes, orienting lug 3 planes with the spray of the surface in rear case component 3 and 4 teflon are oriention benchmark, forming friction slip with steel ball 11 in main grid supporting base 5 two side holes and 12 set screw 7 and 8 pays, the depth of parallelism on the plane of main grid supporting base 5 and 2 liang of planes of housing with set screw 7 and 8 and left and right sides steel ball 11 and 12 regulate, there are upper support cover 14 and lower support seat 13 in two of measuring staff, dynamometer spring 6 is installed in measuring staff 1 time, its two is separately fixed in the hole 9 and 10 on measuring staff 1 and the lower support cover 13, rear case component 3 and 4 is made up of rear cover body 4 and orienting lug 3, and orienting lug 3 is embedded in the rear cover body 4.
