Abstract
The utility model discloses a watch core motor tightening device, which consists of a tightening screw and a positioning pile, wherein, the tail part of the tightening screw is large, and can be inserted into a sinking groove at the bottom of the central hole of the positioning pile; since the tightening screw is directly compressed into the central hole of the positioning pile of a main clamping plate, and the tail part of the tightening screw is larger than the rod part of the tightening screw to form a stage that is similar to a reversing hook shape, so as to lock the main clamping plate, so that the tightening screw is tightly locked to the positioning pile of the main clamping plate, thereby tightly compressing the stator plate on the iron core, so that the stator plate is tightly contacted with the iron core, and the tightening screw is free from rebounding, thereby improving the contact reliability between the stator plate and the iron core; moreover, the loading and disassembling are more convenient, thereby being uneasy to cause the damage of the components, and improving the utilization rate of the components, and reducing the cost.
Description
Technical field
The utility model relates to a kind of timepiece movement motor fastener, relates in particular to the fastener of stator piece and iron core in the timepiece movement.
Background technology
What the fixed form of present domestic watch core motor mainly adopted is:
1, screw cushioning fixed form: this is traditional method, and mainly being provides sub-sheet of pressure given and iron core by screwing screw, and it is tight to make it contact, and its shortcoming is that cost height and assembling speed are slow.
2, not rivet hot fixed form behind the pressure tight loop: the method is by compressing tight loop, pressure is acted on stator piece and the iron core, guarantee the reliable of contact, its shortcoming is that the loosening phenomenon of bounce-back appearance easily takes place tight loop, cause the imprecision that contacts between stator piece and the iron core, influence magnetic conduction.
3, press tight loop after heat rivet clasp decide mode: the method also is by compressing contacting between tight loop assurance stator piece and the iron core, but it is after being pressed into tight loop, and the reference column to the bottom plate tight loop has carried out rivet hot again, to prevent the bounce-back of tight loop.But tight loop is after rivet hot, and dismounting is extremely inconvenient, and easily causes scrapping of part.
4, direct rivet hot reference column mode: the method is that stator piece and iron core are packed into behind the reference column directly the reference column rivet hot, pushes down stator piece and iron core with the upturned melten gel of rivet hot reference column.This mode is dismantled extremely inconvenient, very easily causes scrapping of part.
The utility model content
The purpose of this utility model be to provide a kind of installing/dismounting easily, the timepiece movement motor fastener of fixation.
For achieving the above object, technical solution of the present utility model is:
A kind of timepiece movement motor fastener, it is characterized in that: it is made up of clench nail and reference column; Described reference column is provided with a middle part through hole, and the middle part through hole of reference column can be inserted in described clench nail lower end.
Described clench nail is made up of pressure cap and bar portion, and pressure cap is arranged on the end of bar portion, and the radial dimension of pressure cap is greater than bar portion radial dimension; The diameter of described reference column middle part through hole becomes stationary fit with clench nail bar portion diameter.
Described clench nail also is provided with a fastening part, and pressure cap and fastening part are separately positioned on the two ends of bar portion, and the fastening part radial dimension is slightly larger than bar portion radial dimension, forms a step between bar portion and fastening part; Described reference column middle part via bottoms is provided with a deep gouge, satisfies after clench nail is pressed into the middle part through hole of reference column, and the bar portion of clench nail and the meeting of the step between fastening part holding are in the deep gouge of reference column mesopore bottom.
The fastening part of described clench nail has a vertical short slot, and this short slot extends to the bar portion of clench nail always from the outer end.
The diameter dimension of described clench nail bar portion is greater than clear size of opening in the reference column.
The top or the bottom of described reference column middle part through hole also are provided with an expanded hole.
The top and the bottom of described reference column middle part through hole are respectively equipped with an expanded hole.
The bar portion of described clench nail is a cylinder or multiple edge body.
Described reference column is the positioner that motor is installed in bottom plate.
The usefulness of technique scheme is:
● because the utility model directly utilizes the mesopore that processes on the bottom plate motor reference column location hole as clench nail, in this location hole, be pressed into clench nail, the stationary fit of the middle part through hole by clench nail and reference column, promptly lead to and frictional force between the two, stator piece is closely contacted with iron core.
● because clench nail is provided with a fastening part, this tight portion is slightly larger than the bar portion of clench nail, forms approximate barb-like step, thereby with stator piece being pressed on the iron core tightly, makes that stator piece and iron core are tightr to be contacted, and makes clench nail rebound phenomena can not take place; Fastening part is provided with a vertical short slot, so that the bar of clench nail can be pressed into the middle part through hole of reference column easily.
● because clench nail bar portion diameter dimension is greater than clear size of opening in the reference column, when clench nail is pressed in the reference column through hole, through hole forms interference fit in its bar portion diameter and the reference column, and bar portion stretches out the chap that can rebound of part at expanded hole and forms back taper, thereby clench nail can not rebounded.
The pressure cap that three kinds of above-mentioned schemes have all guaranteed clench nail makes stator piece being pressed on the iron core tightly stator piece closely contact with iron core, improved the reliability that contacts between stator piece and the iron core.And easy to loading and unloading, be difficult for causing scrapping of part, improve the utilance of part, reduce cost.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
