Description

Technical Field

[0001] This utility model belongs to the field of stator processing equipment, and more specifically, it relates to a stator clamping and flipping mechanism. Background Technology

[0002] The stator is the stationary part of the motor that contains the coil windings. During the machining process, the stator usually needs to be machined on multiple sides (both end faces, inner hole, outer circle, etc.). If it is not rotated, the machine tool's cutting tools are limited and cannot complete all the machining surfaces at once.

[0003] The stator needs to be clamped and processed in one direction, and then flipped to another direction to be clamped again to process the other side. In order to flip the stator, a stator clamping and flipping mechanism is often required. However, traditional stator clamping and flipping requires precision to achieve good stator processing. Utility Model Content

[0004] To address the above deficiencies, this utility model provides a stator clamping and flipping mechanism, including a mounting plate, an assembly plate mounted on the bottom of the mounting plate, and a parallel pneumatic gripper fixedly mounted on the bottom of the mounting plate. The feature is that the two output ends of the parallel pneumatic gripper are respectively mounted with an active clamping part and a driven clamping part through fixed connecting blocks.

[0005] The active clamping part includes a housing I. A swing cylinder is installed on the left side of the housing I. The output end of the swing cylinder passes through the housing I and is connected to the internal linkage mechanism I. The housing I is connected to a stator clamping block I through the internal linkage mechanism I.

[0006] The driven clamping part includes a housing II, inside which a linkage mechanism II is installed, and a stator clamping block II connected to the linkage mechanism II;

[0007] Both housing I and housing II are equipped with a detection mechanism for detecting the rotation angle.

[0008] Furthermore, the housing I is sealed by the cover plate I, and the stator clamp I is rotatably mounted on the cover plate I;

[0009] The linkage mechanism I includes a drive shaft fixed to the stator clamp I. The drive shaft is rotatably mounted on the inner wall of the housing I. The drive shaft is connected to the output end of the swing cylinder by a sleeved transmission belt.

[0010] Housing II is sealed by cover plate II, and stator clamp II is rotatably mounted on housing II;

[0011] The linkage mechanism II includes a driven shaft fixed to the stator clamping block II, and the driven shaft is rotatably connected to the cover plate II.

[0012] Furthermore, the detection mechanism includes a proximity switch I and a sensing block I located on the outer wall of housing I, and a proximity switch II and a sensing block II located on the outer wall of housing II;

[0013] There are two proximity switches I, which are located on both sides of the output end of the swing cylinder and are fixedly connected to the cover plate I. The sensing block I is installed at the output end of the swing cylinder to trigger the proximity switches I.

[0014] There are two proximity switches II, which are mounted on the right side of housing II and located on both sides of the driven shaft. The sensing block II is fixed at the end of the driven shaft away from the stator clamping block II and is used to trigger the proximity switches II.

[0015] Furthermore, spacers are installed between stator clamp I and the drive shaft, and between stator clamp II and the driven shaft.

[0016] Furthermore, the outer ring of the drive shaft is fixed with two symmetrical stop fingers. The stop fingers are located outside the housing I, and the positioning bolt is threaded to the outer side wall of the housing I and located at the top of the stop fingers.

[0017] Furthermore, four rectangularly distributed adjustment blocks are fixedly installed on the top of the mounting plate, and the mounting plate is located between the four adjustment blocks. Each adjustment block is L-shaped, and a hexagonal bolt is threaded onto the right-angled inner sidewall of each adjustment block. The end of the hexagonal bolt abuts against the sidewall of the mounting plate.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] With a simple overall structure and convenient control operation, it is more efficient in both use and subsequent maintenance. It can clamp and rotate the stator with precise positioning, thereby improving machining accuracy. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] like Figures 1 to 4 As shown, this embodiment provides a stator clamping and flipping mechanism, including a mounting plate 1, an assembly plate 2 mounted on the bottom of the mounting plate 1, a parallel gripper 3 fixedly mounted on the bottom of the mounting plate 1, and an active gripper and a driven gripper respectively mounted on the two output ends of the parallel gripper 3 through a fixed connecting block 4.

[0028] Four rectangular adjustment blocks 9 are fixedly installed on the top of the assembly plate 2. The mounting plate 1 is located between the four adjustment blocks 9. Each adjustment block 9 is L-shaped. The right-angled inner sidewall of each adjustment block 9 is threaded with a hexagonal bolt 10. The end of the hexagonal bolt 10 abuts against the sidewall of the mounting plate 1. During the stator clamping process, the mounting plate 1 is adjusted according to the hexagonal bolts 10 on the adjustment blocks 9, thereby adjusting the stator clamping blocks I53 and II62 on the parallel pneumatic gripper 3. After the position is adjusted, it is locked with nuts.

[0029] The active clamping part includes a housing I51. A swing cylinder 52 is installed on the left side of the housing I51. The output end of the swing cylinder 52 passes through the housing I51 and is connected to the internal linkage mechanism I. The housing I51 is connected to a stator clamping block I53 through the internal linkage mechanism I.

[0030] In detail, the housing I51 is sealed by the cover plate I54, and the stator clamp I53 is rotatably mounted on the cover plate I54;

[0031] The linkage mechanism I includes a drive shaft 55 fixed to the stator clamping block I53. The drive shaft 55 is rotatably mounted on the inner wall of the housing I51. The drive shaft 55 is connected to the output end of the swing cylinder 52 by a transmission belt 56. The driven clamping part includes a housing II61. The linkage mechanism II and the stator clamping block II62 connected to the linkage mechanism II are installed inside the housing II61.

[0032] Additionally, the outer ring of the drive shaft 55 is fixed with two symmetrical stop fingers 7. The stop fingers 7 are located outside the housing I51. The top of the stop fingers 7 is threaded with a positioning bolt 8, which is threaded to the outer wall of the housing I51. This ensures that after the drive shaft 55 is rotated into position, the positioning bolt 8 abuts against the inner wall of the housing I51, which can stably stop the stator clamp I53 and ensure that the stator is rotated into position.

[0033] In detail, housing II61 is sealed by cover plate II63, stator clamping block II62 is rotatably mounted on housing II61, and linkage mechanism II includes driven shaft 64 fixed to stator clamping block II62, driven shaft 64 is rotatably connected to cover plate II63;

[0034] Both housing I51 and housing II61 are equipped with detection mechanisms for detecting rotation angle. The detection mechanisms include a proximity switch I57 and a sensing block I58 located on the outer wall of housing I51, and a proximity switch II65 and a sensing block II66 located on the outer wall of housing II61. During the swinging of the swing cylinder 52, the stator clamping block II62 on the driven shaft 64 rotates accordingly to achieve the rotation of the stator. At the same time, when the proximity switch II65 senses the sensing block II66, it also ensures that the driven shaft 64 is rotated into place. If there is any misalignment during the process of the stator clamping block II62, the proximity switch II65 will not sense the sensing block II66, further ensuring the accuracy of clamping and rotation.

[0035] There are two proximity switches I57, which are located on both sides of the output end of the swing cylinder 52 and are fixedly connected to the cover plate I54. The sensing block I58 is installed at the output end of the swing cylinder 52 and is used to trigger the proximity switches I57.

[0036] There are two proximity switches II65. The two proximity switches II65 are installed on the right side of the housing II61 and are located on both sides of the driven shaft 64. The sensing block II66 is fixed on the end of the driven shaft 64 away from the stator clamping block II62 and is used to trigger the proximity switches II65.

[0037] It should be noted that pads are installed between stator clamp I53 and drive shaft 55, and between stator clamp II62 and driven shaft 64, to facilitate the replacement of stator clamp I53 and ensure clamping stability.

[0038] In this embodiment, the stator clamping and flipping mechanism unfolds the parallel gripper 3 when clamping the stator, simultaneously opening stator clamping blocks I53 and II62. The stator is placed between them, and the parallel gripper 3 secures the stator clamping blocks I53 and II62. During stator production, the stator needs to be flipped, i.e., rotated 180°. The swing cylinder 52 drives the drive shaft 55 to rotate via the conveyor belt 56. After the swing cylinder 52 swings to its position, when the proximity switch I senses the proximity switch I57, the proximity switch I57 sends a signal to the control system of the equipment (referring to the control system of the overall stator production equipment). The control system then issues an instruction to perform the next action. At the same time, the stop finger 7 on the drive shaft 55 also swings to its position. Under the action of the positioning bolt 8, the stator clamping blocks I53 and II62 are positioned, ensuring that the stator clamping block I53 on the drive shaft 55 stops rotating. During the swing of the swing cylinder 52, the driven shaft 64 also swings, achieving synchronous rotation, thus completing the stator flipping operation.

[0039] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
