The technical implementation is crucial for the comprehensive competitiveness of the equipment and is a key link in the production process.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0031] The following is combined with Figure 1 -Attached Figure 9 , describes in detail the technical solutions provided by each embodiment of the present invention.

[0032] Example 1: Reference Figures 1 - 4 A shell and double stator alignment mechanism includes a mounting back plate 13, and also includes: a sliding back plate 121 is slidably connected to the mounting back plate 13, and the sliding back plate 121 is fixedly connected to the upper and lower cylinders 12 of the mechanism, and the output ends of the upper and lower cylinders 12 of the mechanism are fixedly connected to the lifting bracket 25; the lifting bracket 25 is fixedly connected to the first XY floating mechanism 24, and the first XY floating mechanism 24 is fixedly connected to the shell guide block 21, and the lower part of the first XY floating mechanism 24 is fixedly connected to the stator guide clamp 22; the mounting back plate 13 is fixedly connected to the double-hole shell 14, when the shell guide block 21 is inserted into the inner hole of the double-hole shell 14, the first XY floating mechanism 24 and the stator guide clamp 22 are offset following the shell guide block 21; a support base plate 4 is provided below the stator guide clamp 22, and the stator body 41 is clamped above the support base plate 4.

[0033] In the present invention, a double-hole housing 14 is fixedly connected to the mounting backplane 13 to serve as a template. The sliding backplane 121 can slide horizontally on the mounting backplane 13. The mechanism up-down cylinder 12 is fixedly connected to the sliding backplane 121. The mechanism up-down cylinder 12 can control the lifting bracket 25 to move up and down. Through the combination of the sliding backplane 121 and the mechanism up-down cylinder 12, the lifting bracket 25 can move on the horizontal plane of the mounting backplane 13;

[0034] The first XY floating mechanism 24 is fixedly connected to the lifting bracket 25. The upper part of the first XY floating mechanism 24 can float, move on the horizontal plane, be centrally locked and locked at any position. The housing guide block 21 is fixed on the first XY floating mechanism 24 and moves synchronously with the first XY floating mechanism 24. At the same time, the stator guide jaw 22 also moves synchronously with the first XY floating mechanism 24, and the clamping center point of the stator guide jaw 22 corresponds to the center of the housing guide block 21. The stator guide jaw 22, the first XY floating mechanism 24 and the housing guide block 21 move synchronously. When the stator guide jaw 22 carries the stator body 41, the position where the housing guide block 21 moves and positions will be vertically corresponding to the position of the stator body 41. Preferably, the housing guide block 21 is a conical guide block. After the stator guide jaw 22 clamps the stator body 41, the sliding backplane 121 drives the lifting bracket 25 to move below the double-hole housing 14. The mechanism up-down cylinder 12 drives the lifting bracket 25 to move upward. The first XY floating mechanism 24 opens. The housing guide block 21 contacts the inner hole positioning ring of the double-hole housing 14 and continuously corrects the position of the housing guide block 21 as the lifting bracket 25 drives the housing guide block 21 to rise until the housing guide block 21 is completely embedded in the double-hole housing 14. During this process, the first XY floating mechanism 24, the stator guide jaw 22 and the stator body 41 all move synchronously with the housing guide block 21. Thus, when the housing guide block 21 can be completely embedded in the double-hole housing 14, the center of the stator body 41 will also correspond to the center of the double-hole housing 14, thereby completing the centering of the stator body 41. After the centering is completed, the mechanism up-down cylinder 12 drives the lifting bracket 25 to move downward to place the stator body 41 back on the support base plate 4 and re-clamp and record the position of the centered stator body 41. Then, the stator guide jaw 22 can be released, and the lifting bracket 25 can be reset, thus facilitating the subsequent assembly of the stator body 41.

[0035] Example 2: Refer to Figures 1 - 9, a housing and a double-stator centering mechanism, which is basically the same as that in Embodiment 1. Further, a horizontal transfer cylinder 11 is fixedly connected to the mounting backplane 13. The output end of the horizontal transfer cylinder 11 is fixedly connected to the sliding backplane 121. A jaw cylinder 23 is fixedly connected below the lifting bracket 25. The jaw cylinder 23 is used to control the opening and closing of the stator guiding jaws 22. A base 34 is fixedly connected to the support base plate 4. A positioning seat 33 is fixedly connected to the base 34. An inner support flap 31 is fixedly connected to the positioning seat 33. A plugging rod 35 is slidably connected inside the positioning seat 33. A spreading spring 32 is connected between the plugging rod 35 and the positioning seat 33. A stator positioning support block 42 is provided on the support base plate 4. A claw 44 is rotatably connected to the support base plate 4. A bottom positioning pin 43 is slidably connected to the support base plate 4. The bottom positioning pin 43 is rotatably connected to the claw 44. A support frame 51 is fixedly connected below the support base plate 4. A jacking cylinder 53 is fixedly connected to the support frame 51. The output end of the jacking cylinder 53 is fixedly connected to a support plate 57. A lifting support plate 55 is fixedly connected to the support plate 57. A guide rod 54 is fixedly connected to the lifting support plate 55. The guide rod 54 is slidably connected to the support frame 51. A pushing cylinder 52 is fixedly connected to the support plate 57. The output end of the pushing cylinder 52 is fixedly connected to a lifting frame 58. The lifting frame 58 is slidably connected to the lifting support plate 55. A locking collar 561 is provided on the lifting support plate 55. The locking collar 561 is connected to the bottom positioning pin 43. A second XY floating mechanism 59 is fixedly connected to the lifting frame 58. An upper support positioning sleeve 56 is fixedly connected to the second XY floating mechanism 59.

[0036] In the present invention, the horizontal transfer cylinder 11 is fixedly connected to the mounting backplane 13. A slide rail is fixedly connected to the mounting backplane 13. The sliding backplane 121 slides on the slide rail. The horizontal transfer cylinder 11 can push the sliding backplane 121 to slide on the slide rail, and thus can drive the lifting bracket 25 to slide horizontally. The jaw cylinder 23 can control the opening and closing of the stator guiding jaws 22, so as to control the clamping of the stator body 41.

[0037] The base 34 is fixed on the stator positioning support block 42. The base 34 is fixedly connected to the positioning seat 33. The inner support flap 31 is fixed on the positioning seat 33. The top part of the positioning seat 33 is divided into three petals. The top part of the positioning seat 33 can be expanded outwards. The inner support flap 31 has a certain deformation ability. The plugging rod 35 is slidably connected inside the positioning seat 33. When the plugging rod 35 is jacked up and moved upwards, the plugging rod 35 pushes the top part of the positioning seat 33 outwards. The inner support flap 31 is also pushed outwards by the spreading force of the positioning seat 33, so as to fix the stator body 41 from the inside.

[0038] The lifting cylinder 53 is fixed on the supporting frame 51, and the lifting cylinder 53 can push the supporting plate 57 to move up and down. The guide rod 54 is slidably connected to the supporting frame 51, so as to provide a guide for the lifting and lowering of the supporting plate 57 to prevent the supporting frame 51 from deviating during movement. The lifting frame 58 is fixedly connected with a pushing cylinder 52, and the pushing cylinder 52 can push the lifting frame 58 to lift and lower within a small range. The lifting frame 58 is fixedly connected to the second XY floating mechanism 59, and the second XY floating mechanism 59 is fixedly connected with an upper support positioning sleeve 56, so that the pushing cylinder 52 can push the upper support positioning sleeve 56 to move up and down. When the upper support positioning sleeve 56 moves up, it will establish a floating connection with the stator positioning support block 42. At this time, when the second XY floating mechanism 59 moves on the horizontal plane, it will synchronously drive the upper support positioning sleeve 56 and the stator positioning support block 42 to move. When the stator body 41 moves down to the positioning seat 33 following the lifting bracket 25 after centering, the second XY floating mechanism 59 is unlocked. At this time, the positioning seat 33, the stator positioning support block 42 and the upper support positioning sleeve 56 can all move within a small range. When the stator body 41 is inserted into the inner support clamp 31, the position of the positioning seat 33 will be corrected. The positioning seat 33 will drive the stator positioning support block 42, the upper support positioning sleeve 56 and the second XY floating mechanism 59 to move. After the movement is completed, the second XY floating mechanism 59 is locked, thereby recording the position of the stator body 41 after centering. The subsequent stator body 41 can be directly placed on the positioning seat 33 and the inner support clamp 31 for clamping and subsequent assembly operations, so that the stator does not need to be centered every time it is assembled, thereby being able to save a lot of time consumed in centering while ensuring the accuracy of centering, thereby increasing the efficiency of assembly.

[0039] A cylinder is fixedly connected to the lifting support plate 55, and the locking sleeve 561 is connected to the output end of the cylinder on the lifting support plate 55. The locking sleeve 561 is sleeved on the bottom positioning pin 43. When the locking sleeve 561 moves up, it will drive the bottom positioning pin 43 to move up, and the bottom positioning pin 43 will drive the claw 44 to rotate to resist the stator positioning support block 42 and press the stator positioning support block 42 to move downward. When the stator positioning support block 42 moves downward, it will drive the positioning seat 33 to move together, and the plug-in rod 35 will be resisted by the upper support positioning sleeve 56 and cannot move downward, thereby The plug-in rod 35 will move upward in the positioning seat 33, and then squeeze the positioning seat 33 and the inner support clip 31 to open outward, thereby realizing the operation of clamping the stator body 41. Similarly, when the cylinder on the lifting support plate 55 drives the locking sleeve 561 to move downward, the locking sleeve 561 will pull the bottom positioning pin 43 to move downward, and the bottom positioning pin 43 pulls the claw 44 to flip upward to release the squeezing of the stator positioning support block 42, so that the stator positioning support block 42 can move upward under the action of the opening spring 32, thereby releasing the clamping of the stator body 41.

[0040] When in use, the user first places the stator body 41 on the positioning seat 33, then starts the horizontal transfer cylinder 11 and the mechanism up-down cylinder 12 to control the stator guiding jaw 22 to move above the stator body 41 and starts the jaw cylinder 23 to control the stator guiding jaw 22 to clamp the stator body 41. During this process, the first XY floating mechanism 24 is in an unlocked and floating state, so as to avoid damage to the stator body 41 or the positioning seat 33 caused by the inconsistent position of the stator guiding jaw 22 and the stator positioning support block 42 when clamping the stator body 41. After clamping the stator body 41, the lifting bracket 25 can be controlled to move below the double-cavity housing 14 and the housing guiding block 21 can be docked and inserted into the double-cavity housing 14 to complete the centering of the stator body 41. After the centering is completed, the lifting bracket 25 is controlled to move above the positioning seat 33 again and the stator body 41 is placed back on the positioning seat 33. When the stator body 41 is placed back on the positioning seat 33 again, it is necessary to first control the pushing cylinder 52 to push the lifting frame 58 upward to establish a floating connection with the stator positioning support block 42 and release the limit of the second XY floating mechanism 59. After establishing the floating connection, when the re-centered stator body 41 is inserted into the positioning seat 33, the position of the positioning seat 33 will be automatically corrected. After the positioning is completed, the second XY floating mechanism 59 is locked again to complete the recording of the new point.

[0041] The above is only a preferred embodiment of the present invention, and it is not intended to limit the present invention in any form. Although the present invention has been disclosed above with the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-mentioned technical content as an equivalent embodiment of equivalent changes within the scope of the technical solution of the present invention. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
