The present invention guarantees that with assembling or assembling mode (but not machining mode) axis of guide and measuring staff have very high dynamic parallel accuracy, and measuring rod seat connects into an integral body with measuring staff and the axis of guide, is to realize the secondary key point of high kinematic accuracy guiding.
A kind of structure of described stopper slot is included in limiting plate and the limited block of the forward and backward setting of the axis of guide, limited block is located on the watchcase base plate, the pilot hole of offering on the limiting plate and locating shaft clearance fit, locating shaft is located on the watchcase support plate parallel with the watchcase base plate in the watchcase, regulate the axis of guide after the movement clearance between limited block and the limiting plate, fixedly limiting plate is on locating shaft.
The movement clearance of described limiting plate and limited block and the axis of guide also is to adopt assembling or assembling mode to regulate, and can realize only clearance fit, satisfies the high repetitive positioning accuracy of measuring staff and kinematic accuracy.
Described limited block is the set screw of being located on the watchcase base plate, can control the convenient rotation of regulating measuring staff, the main grid on the convenient adjusting measuring rod seat and the depth of parallelism of watchcase base plate.
Coupling gap also can be realized by the assembling mode between described secondary grid and the main grid, its a kind of structure is that secondary grid are fixedly arranged on the axle sleeve of even layout in the face of main grid, described axle sleeve gap is matched with in the axis hole that correspondence is offered on the watchcase base plate, after regulating coupling gap between secondary grid and the main grid with assembling or assembling mode, fixed hub is in axis hole.
Advantage of the present invention:
1, assembly type digital display indicating gauge mechanical component of the present invention adopts assembling or packaging technology, realizes the manufacturing of high precision member to drop into cheaply.
2, parts such as the axis of guide of described high precision member, axle sleeve, measuring staff can adopt standard component, and members such as watchcase, watchcase base plate, watchcase support plate can adopt expanded material or die casting, Sheet Metal Forming Technology production.
3, adopt standard component (axle, cover, bar etc.) and expanded material or die casting, Sheet Metal Forming Technology production (watchcase, watchcase base plate, watchcase support plate etc.), can effectively reduce the equipment input, be beneficial to the quick industrialization of product.
4, the present invention can be combined into digital display indicating gauge or linear displacement transducer with multiple sensors such as holding grid circuit, magnetic grid, current vortex.
