Technical Field
[0001] The utility model relates to an assembling machine, in particular to a stator alignment auxiliary device for the assembling machine. Background Art
[0002] With the rapid development of permanent magnet motors, different types of permanent magnet motors are used in more and more occasions. The motor stator is an important part of motors such as generators or motors. The stator consists of three parts: stator core, stator winding and frame. The main function of the stator is to generate a rotating magnetic field.
[0003] The alignment tooling of traditional assembly machines is a special tooling for specific motors. On the one hand, the alignment accuracy is not high. On the other hand, there are more and more types and styles of permanent magnet motors. In this way, the special tooling designed for a specific motor can only be adapted to one specific motor. In order to produce multiple models of products, companies have to make a large number of tooling to adapt to specific motors, which greatly increases production costs. Utility Model Content
[0004] The purpose of the utility model is to provide a high-precision universal assembly machine stator alignment tool, so that one tool can solve the alignment of various types of motors, with high alignment accuracy and fast alignment speed, greatly improving production efficiency and reducing production costs, thereby adapting to diversified production.
[0005] To achieve the above-mentioned purpose, the utility model provides a high-precision universal assembly machine stator alignment tool, including an annular positioning hoop bracket, a center frame roller, a length adjustment column, a dial indicator positioning frame and a dial indicator; wherein the annular positioning hoop bracket is a hoop structure, one side of the hoop structure is open, and a fastening structure that can adjust the diameter of the hoop structure is arranged at the opening; a plurality of center frame rollers are arranged at intervals on the inner wall of the hoop structure, and each center frame roller faces the center of the hoop structure; a length adjustment column is extended and fixed along the radial direction of the hoop structure, and one end of the length adjustment column is vertically fixed to the outer ring surface of the hoop structure, and a dial indicator positioning frame is detachably fixed on the column; the dial indicator is fixed on the dial indicator positioning frame.
[0006] As a preferred embodiment, the dial indicator fixing platform is a prism structure that is wide at the top and thin at the bottom, wherein a positioning hole is provided at the top of the prism structure, and a length adjustment column passes through the positioning hole so that the dial indicator fixing platform is directionally suspended on the length adjustment column.
[0007] As a preferred embodiment, a positioning plate is provided at the bottom of the length adjustment column, and the positioning plate is used to fix and position the dial indicator so that the dial indicator is parallel to the plane of the hoop structure.
[0008] As a preferred embodiment, a fixing needle is provided at the bottom of the dial indicator, and the fixing needle passes through the positioning hole on the positioning plate and has a fixed snap-fit structure on the tip side thereof, thereby fixing the positioning dial indicator and making the dial indicator parallel to the plane of the hoop structure.
[0009] As a preferred embodiment, the fixed engaging structure is a bolt structure or a spring buckle structure.
[0010] As a preferred embodiment, the housing of the dial indicator and the positioning plate are integrally formed.
[0011] As a preferred embodiment, the fastening structure capable of adjusting the diameter of the hoop structure comprises a pair of hoop positioning blocks and a butterfly locking screw arranged on two annular tips at the opening. The hoop positioning blocks are provided with hoop positioning through holes at corresponding positions, and the butterfly locking screw passes through the two hoop positioning through holes to lock the hoop structure.
[0012] As a preferred embodiment, the hoop structure includes two ring arms and a rotating shaft. The two ring arms are rotatably connected and fixed together by the rotating shaft arranged on the opposite side of the opening, so that they form a circular ring when closed, and the rotating shaft is used to open and close the two ring arms of the hoop.
[0013] As a preferred embodiment, a plurality of center frame rollers are evenly spaced apart on the inner wall of the hoop structure, and each center frame roller faces the center of the hoop structure.
[0014] As a preferred embodiment, three center frame rollers are evenly spaced on the inner wall of the hoop structure, each center frame roller faces the center of the hoop structure and is fixed to the hoop structure by a bolt structure.
[0015] According to the inventor's research, in the prior art, it is necessary to make a special fixed-size tooling in advance according to the size of the motor. This is because the stop size of the general tooling is fixed. When the stop changes, it cannot be used, that is, a special tooling, and such a special tooling has low positioning accuracy. For companies with a single product, some special positioning tooling can be made for quick alignment, but for companies with a large variety of products, it is time-consuming and labor-intensive to make a large number of tooling, which is not conducive to reducing costs and increasing efficiency. Such a special tooling can only find a motor with a stop size, which greatly increases production costs.
[0016] In addition, in the prior art, the alignment of the stator of a specific assembly machine using a special fixed-size tooling of the motor is actually just putting it into the tooling and observing whether the length of the gap x between the inner circle and the core shaft is within the error range, so the alignment accuracy is very low.
[0017] The shortcomings of the prior art are as follows:
[0018] 1. When using special tooling for alignment, the specific left and right, up and down deviation cannot be measured specifically. Only through continuous attempts can a relatively central position be finally found. The specific deviation cannot be digitized, and the alignment efficiency and accuracy are extremely low.
[0019] 2. Traditional tooling alignment judges the centering by the tightness of the tooling when it is put in and taken out. The conclusions may vary depending on the feel of the individual, so it is difficult to guarantee accuracy and requires professional personnel to measure.
[0020] 3. Traditional tooling is used for one machine only and cannot meet the needs of various motor models. It has a narrow scope of application and high alignment cost.
[0021] Compared with the prior art, the utility model realizes a tooling to solve the alignment of various types of motors, has high alignment accuracy and fast alignment speed, can greatly improve production efficiency, reduce production costs, and thus adapt to diversified production.

[0033] Hereinafter, an implementation of the high-precision universal assembly machine stator alignment tool of the present invention will be described with reference to the accompanying drawings.
[0034] The embodiments described herein are specific embodiments of the present invention, which are used to illustrate the concept of the present invention, are explanatory and exemplary, and should not be interpreted as limiting the embodiments of the present invention and the scope of the present invention. In addition to the embodiments described herein, those skilled in the art can also adopt other obvious technical solutions based on the contents disclosed in the claims and the specification of this application, including technical solutions that adopt any obvious replacement and modification of the embodiments described herein.
[0035] The drawings of this specification are schematic diagrams, which assist in explaining the concept of the utility model and schematically show the shapes of various parts and their mutual relationships. Please note that in order to clearly show the structure of various components of the embodiments of the utility model, the drawings are not necessarily drawn in the same proportion.
[0036] The alignment and installation principle of the present invention and the alignment and installation principle of the prior art as a comparison are first described below.
[0037] Figure 6a This is the principle diagram before the stator of the assembly machine is aligned. Figure 6b This is the principle diagram of the assembly machine after the stator is aligned.
[0038] like Figure 6a and 6b As shown, the assembly machine stator 8 is fixed on the assembly machine platform 9, and the human eye aligns the assembly machine core shaft 7. The principle steps are as follows:
[0039] 1. Insert the motor stator into the assembly machine shaft.
[0040] 2. Fix the motor stator on the assembly machine platform.
[0041] 3. Observe the approximate values of X1, X2, Y1, and Y2 with the naked eye.
[0042] 4. Coaxiality estimation: X=X1-X2, Y=Y1-Y2.
[0043] 5. Adjust the assembly machine platform by feel, moving it up, down, left, and right, until X1=X2 and Y1=Y2.
[0044] Because the existing alignment is based on visual observation and feeling, and there is actually no precise measurement of the values of X1, X2, Y1, and Y2, the alignment accuracy is very low.
[0045] Figure 7a The present invention is a schematic diagram of the principle of aligning tooling in the prior art. Figure 7b It is a schematic diagram of the principle of tooling alignment in the prior art.
[0046] like Figure 7a and 7b As shown, in the prior art, it is necessary to make a special fixed-size tooling in advance according to the size of the motor. This is because the stop size of a general tooling is fixed. When the stop changes, it cannot be used, that is, a special tooling, and such a special tooling has low positioning accuracy. For companies with a single product, some special positioning tooling can be made for quick alignment, but for companies with a large variety of products, it is time-consuming and labor-intensive to make a large number of tooling, which is not conducive to reducing costs and increasing efficiency. Such a special tooling can only find a motor with a stop size, which greatly increases production costs.
[0047] In the prior art, the alignment of the stator of a specific assembly machine using a special fixed-size tooling of the motor is actually just putting it into the tooling and observing whether the length of the gap x between the inner circle and the core shaft is within the error range, so the alignment accuracy is very low.
[0048] Figure 8 FIG. 1 is a schematic diagram of the alignment installation principle of the alignment tool in the prior art. Figure 8 As shown, the prior art adopts mechanical positioning, firstly, the positioning plate of the traditional tooling 10 is closely attached to the assembly machine core shaft 7, and the housing position of the assembly machine stator 8 is adjusted, and the alignment is judged by naked eye and hand feeling. The specific steps of alignment are:
[0049] 1. Fit the outer circular edge of the specially made fixed-size tooling to the stop.
[0050] 2. Observe the gap x between the inner circle and the core shaft with the naked eye, and adjust the assembly machine platform to see if it is aligned.
[0051] 3. Observe the gap x between the inner circle and the core shaft by hand and with the naked eye. Repeat the previous step until the gap x between the inner circle and the core shaft is within the error range by naked eye observation. The alignment is completed.
[0052] Based on the above principles, an embodiment of the high-precision universal assembly machine stator alignment tooling of the utility model is described below.

By adjusting the position of the dial indicator positioning frame 6 on the length adjustment column 4, it can cope with motors of different sizes and models, and has high versatility.
[0055] The tooling of the utility model is fixed on the assembly machine core shaft 7 and can be rotated 360 degrees with high precision. The dial indicator positioning frame 6 is adjusted, and then the tooling is rotated to adjust the housing position through the dial indicator 15 reading.
[0056] like Figure 1 and Figure 2 As shown, during the installation measurement, the assembly machine stator 8 is fixed on the assembly machine platform 9, and then the positioning hoop bracket 1 of the tooling of the utility model is fixed on the assembly machine core shaft 7, and the position of the dial indicator 5 is adjusted by the length adjustment column 4 to adapt to motors of different diameters, and then the tightness of the positioning hoop bracket 1 is adjusted by the fastening structure 3, and finally the alignment measurement is performed:
[0057] 1. The tooling of the utility model can be rotated 360 degrees.
[0058] 2. Use the swing dial indicator 5 to read the coaxiality on the dial of dial indicator 5.
[0059] 3. When the tooling rotates one circle and the pointer stops swinging, the alignment is complete.
[0060] After alignment by the tooling of the utility model, the coaxiality difference is less than 0.01MM, so the alignment accuracy is extremely high.
