Abstract
The utility model discloses a clamp used for assembling a voice coil motor rotor. The clamp comprises a clamp body which is internally provided with a cylinder hole. The internal wall of the upper end of the clamp body is provided with annular step surfaces which extend upwards in steps. The upper end of the clamp body is vertically provided with multiple arc-shaped abdicated notches, of which the height is greater than the sum of the height of the annular step surfaces. Compared with clamps in the prior art, a coil and a lens bearing body can be positioned by using the clamp used for assembling the voice coil motor rotor so that concentricity of assembling of two components is ensured, characteristics of the finished voice coil motors are ensured and generation of defective products in the following assembling is reduced, relative accuracy of the two components is realized, and thus influence of accumulative error in the assembling is reduced and assembling accuracy is ensured. The main body adopts the central cylinder hole structure so that the weight of the clamp is greatly reduced, and the central cylinder hole is utilized to conduct heat in the technology so that technical requirements can be more easily met in the product assembling.
Description
Technical field
The utility model relates to the improvement of electromagnetic technology field voice coil motor assembling product technique, particularly a kind of voice coil motor rotor assembling fixture.
Background technology
In existing micromachine assembling process, the design of positioning fixture only adopts a kind of location, is then utilizing component after positioning to position another component.When two component accuracy errors are larger, the semi-finished product after having assembled cannot guarantee the relative accuracy of two component, can cause the great bad of production process.
Summary of the invention
The purpose of this utility model is the fixture in the time of will providing a kind of voice coil motor rotor assembling to use.
For achieving the above object, the utility model is implemented according to following technical scheme:
A kind of rotor assembling fixture of voice coil motor, comprise chuck body, in described chuck body, be provided with cylindrical hole, the annular table terrace that the inwall setting of chuck body upper end makes progress step by step, chuck body upper end is longitudinally provided with a plurality of arcs breach of stepping down, and the step down height of breach of arc is greater than the height sum of annular table terrace.
As preferably, described annular table terrace is set to 2-8 rank.
Compared with prior art, voice coil motor rotor assembling fixture of the present utility model, coil can be become carrier all to utilize fixture location with camera lens, guarantee the concentricity of two assembling parts, be of value to and guarantee the characteristic of voice coil motor finished product and reduce generation bad while assembling below, realize the relative accuracy of two kinds of components, thereby reduce the impact of assembling cumulative errors, guaranteed assembly precision; Adopt main center's cylindrical hole structure, clamp weight is reduced greatly, and in technique, utilize center cylindrical hole to carry out heat conduction, make product in assembling, more easily reach specification requirement.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
Fig. 2 is profile of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described, in illustrative examples and the explanation of this utility model, is used for explaining the utility model, but not as to restriction of the present utility model.
The rotor assembling fixture of voice coil motor as shown in Figure 1 and Figure 2, comprise chuck body 1, in described chuck body 1, be provided with cylindrical hole 3, the inwall of chuck body 1 upper end arranges the annular table terrace 4 that 2-8 rank make progress step by step, chuck body 1 upper end is longitudinally provided with a plurality of arcs breach 2 of stepping down, and the step down height of breach 2 of arc is greater than the height sum of annular table terrace 4.
When the utility model is used: the coil of the rotor of voice coil motor can be become carrier to be fixed on adjacent annular table terrace 4 with camera lens, guarantee the concentricity of two assembling parts, be of value to and guarantee the characteristic of voice coil motor finished product and reduce generation bad while assembling below, realize the relative accuracy of two kinds of components, thereby reduce the impact of assembling cumulative errors, guaranteed assembly precision; Adopt main center's cylindrical hole 3 structures, chuck body 1 weight is reduced greatly, and in technique, utilize center cylindrical hole to carry out heat conduction, make product in assembling, more easily reach specification requirement.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical solution of the utility model, within all falling into protection range of the present utility model.
