Abstract
The utility model provides a positioning clamp during hoisting of an accelerometer. The clamp comprises a power output system and a positioning tool. The power output system is formed by a power supply and a motor. The positioning tool comprises an upper cover, a body, a pedestal and a meter core fixing screw. The pedestal is a boss structure having a T-shaped cross section and is formed by a cylinder and a protruded shaft that are coaxial. The body is a cylindrical cavity structure having two coaxial stepped holes. A meter case is disposed inside the cavity of the body through the screw. The meter core is fixedly disposed at the lower part of the meter core fixing screw that passes through the upper cover to allow the meter core to be hung in the cavity of the body. The upper cover is in mechanical joint with one side of the body, and the pedestal is in mechanical joint with the other side of the body. The protruded shaft is in mechanical joint with a rotating shaft of the motor. The protruded shaft, the rotating shaft of the motor, a meter case central axis and a meter core central axis are horizontal. The clamp can effectively improve quality and reliability of accelerometer product assembly.
Description
Technical field
The utility model relates to the positioning fixture in a kind of accelerometer hoisting process, belongs to field of mechanical technique.
Background technology
The quartz flexible accelerometer gauge outfit is assembled by watch core and watchcase, and watch core is coated on unsettled being fixed in the housing cavity of tackifier of inner walls by annular.After watch core and watchcase attaching complete, desirable state is, watch core and housing without directly contacting, between watch core and housing bondline thickness be evenly distributed and bonding firmly.The structure that existing watch core and watchcase assemble positioning fixture used mainly is divided into upper cover and two ingredients of main body; Upper cover by dog screw fixedly watch core, main body by the fixing watchcase of screw.After watchcase inwall adhesive coated completes, by fastening clamp upper cover and jig main body, make watch core be suspended to the watchcase cavity and produce and contact with the tackifier that is coated on the watchcase inwall.In the adhesive solidification process, fixture will be statically placed in the baking oven pallet, and now the watchcase inwall is perpendicular to surface level and keep static.Because the mobility of organic tackifier can significantly increase in the curing process that heats up, thereby cause the watch core applied under normal temperature and the tackifier between housing " soften " in solidification process and trickle under graviational interaction bottom watchcase.This uncontrollable trickling phenomenon, after can making the accelerometer gauge outfit solidify, bonding agent skewness between watch core and housing, the bond stress produced is asymmetric, finally cause the drift that changes of the alignment error angle index of accelerometer, affect the acceleration measuring accuracy of measurement, simultaneously the tackifier skewness also directly affects insulating property between watch core and housing and bonding reliability.
The utility model content
The purpose of this utility model is to overcome the prior art deficiency, and a kind of positioning fixture that improves accelerometer product assembly quality and reliability is provided.
Technical solution of the present utility model: the positioning fixture in a kind of accelerometer hoisting process, comprise the power take-off system positioning tool of unifying, wherein power output system is comprised of power supply and motor, positioning tool comprises upper cover, main body, base and watch core gib screw, base is that cross section is T-shaped round boss structure, by coaxial round platform and protruding axle, formed, the cylindrical cavity structure of two coaxial shoulder holes of processing centered by main body, watchcase is arranged in the cavity of main body by screw, watch core is fixedly mounted on watch core gib screw lower end, the watch core gib screw is suspended on watch core in the cavity of main body through upper cover, upper cover and main body one side mechanical connection, base and main body opposite side mechanical connection, the rotation axis mechanical connection of protruding axle and motor, protruding axle, motor rotation axis, watchcase central shaft and watch core central shaft are horizontal direction.
Described upper cover is cirque structure, and the diametric(al) of cirque structure arranges overarm, and the processing of annulus circle centre position is for locating the through hole of watch core gib screw.
The central shaft of described protruding axle and motor rotation axis is coaxial.
The utility model beneficial effect compared with prior art:
(1) the utility model makes watchcase inwall horizontal positioned, and plane, tackifier place, perpendicular to surface level, has effectively overcome accelerometer hoisting process tackifier and trickled to the watchcase bottom;
(2) the utility model can significantly improve the bonding strength between accelerometer watch core and housing;
(3) the utility model can effectively improve accelerometer product assembly quality and reliability.
