Background
The voice coil motor is a direct drive motor in a special form, and has the advantages of simple structure, small size, high precision and the like. In recent years, with the improvement of the performance requirements of fast and high-precision positioning systems and the rapid development of voice coil motor technology, voice coil motors are not only widely used in precision positioning systems such as magnetic disks and laser record positioning, but also widely used in high-speed and high-frequency excitation of various forms.
When the voice coil motor is installed, because a certain gap exists between the rotor and the stator of the voice coil motor, relative sliding is easily generated during installation, so that a frame is formed, the concentricity of the stator and the rotor during installation is difficult to guarantee, the precision during use is influenced, and a large error is easily generated.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough among the prior art, provide a can keep installing the motor frock of concentricity.
The utility model aims at realizing through the following technical scheme:
a motor tool capable of keeping a voice coil motor concentrically mounted comprises an upper shell and a lower shell which are symmetrically arranged, wherein the upper shell and the lower shell are both of semicircular structures; the two sides of the upper shell and the lower shell are both provided with connecting plates, the upper ends of the upper shell and the lower shell are both provided with annular bulges used for fixing the rotor, and an installation cavity is formed between the upper shell and the lower shell; and the connecting plate is correspondingly provided with a connecting hole.
Furthermore, the mounting cavity and the stator of the voice coil motor are in transition fit and concentric with each other, and the annular bulge and the rotor of the voice coil motor are in transition fit and concentric with each other.
Compared with the prior art, the utility model discloses a beneficial effect that technical scheme brought is:
1. the mounting cavity of the tool is in transition fit with and concentric with the stator of the voice coil motor, and the annular convex surface of the tool is in transition fit with and concentric with the rotor of the voice coil motor. Through set up cyclic annular arch in the upper end of last casing and lower casing, when the active cell of voice coil motor was installed to this department, the active cell can receive cyclic annular bellied jamming to can not take place to rock, make the active cell keep concentric with cyclic annular arch. After the lower cavity is symmetrically installed, the stator is sleeved from the lower end, and the stator is clamped into the installation cavity and keeps concentric with the installation cavity. Because the mounting cavity is concentric with the annular bulge, the stator and the rotor of the voice coil motor can be kept concentric. The tool greatly improves the concentricity of the stator and the rotor of the voice coil motor. And the voice coil motor is screwed up and fixed by bolts after the installation, so that the stability is good, and the voice coil motor is convenient to disassemble after being installed on a mechanical structure.
2. The utility model discloses frock simple structure, precision height, rigidity are big, the dismantlement is convenient, under the condition that need not change voice coil motor self structure, the homocentric of stator and active cell when alright guaranteeing the installation.

Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The utility model discloses it is sharp cylinder type voice coil motor that it is directed against, the frock size that the size that is different according to the model is different also can be different, because the mechanical structure required precision that voice coil motor used is higher, so add man-hour, the tolerance level of cyclic annular arch and installation cavity is accurate, and the material that the frock used is the aluminum alloy, because the rigidity intensity of aluminum alloy is high, and the quality is light, the cost is lower, machine-shaping is good, accords with the utility model discloses it is required, add man-hour and adopt digit control machine tool processing and do certain processing to surface roughness.
As shown in fig. 1 to 3, the utility model provides a motor tool capable of keeping a voice coil motor concentrically installed, which comprises an upper shell 2 and a lower shell 6 symmetrically arranged with each other, wherein the upper shell 2 and the lower shell 6 are both in a semicircular structure; connecting plates are arranged on two sides of the upper shell 2 and the lower shell 6, and threaded through holes 4 are correspondingly arranged on the connecting plates;
the upper ends of the upper shell 2 and the lower shell 6 are both provided with annular bulges 3 for fixing the voice coil motor rotor 1, and the annular bulges 3 are main working parts and are matched and connected with the voice coil motor rotor 1; an installation cavity 5 is formed between the upper shell 2 and the lower shell 6 after the installation; the lower end of the mounting cavity 5 is provided with a mounting opening for mounting a voice coil motor stator 7.
Referring to fig. 1, firstly, the annular convex surface 3 of the upper shell 2 is matched and connected with the voice coil motor rotor 1, then the lower shell 6 is symmetrically installed at the other side of the voice coil motor rotor 1, and the upper ends of the upper shell 2 and the lower shell 6 are ensured to be at the same height as the upper end of the voice coil motor rotor 1. Then, the voice coil motor stator 7 is sleeved into the mounting cavity 5 from a mounting opening below the mounting cavity 5, a bolt is plugged into the threaded through hole 4, and the bolt is screwed by a nut, so that the mounting is completed. Later with voice coil motor installation in the mechanical structure that needs were used, after being connected voice coil motor active cell 1 and voice coil motor stator 7 with mechanical structure, unscrew the nut on the connecting plate and take out the bolt, dismantle upper casing 2 and lower casing 6, alright solve voice coil motor when the installation stator and the endocentric problem of active cell.
