Description

Technical Field

[0001] This utility model relates to the field of motor stator processing technology, specifically a set of auxiliary fixtures for stator processing. Background Technology

[0002] As a core component of an electric motor, the stator's machining accuracy directly determines the motor's operating performance, efficiency, and service life. During stator machining, especially in critical processes such as grinding and cutting, the stator needs to be stably and reliably clamped and fixed to prevent displacement or shaking during machining, thus ensuring machining accuracy. Existing stator fixtures have poor adjustment flexibility and are mostly designed for stators of specific specifications, making it difficult to adapt to annular stator parts with different inner diameters and sizes, resulting in poor versatility. At the same time, if the metal shavings generated during machining are not cleaned and collected in a timely and effective manner, they will not only scatter into the machining equipment and working environment, affecting the normal operation of subsequent machining processes and increasing equipment maintenance costs, but may also pose a potential threat to the personal safety of operators. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a stator machining auxiliary fixture set, comprising: Base; The column is fixedly installed at the top of the base; Collection boxes are fixedly installed on both the left and right sides of the top of the base; An auxiliary clamping mechanism is provided at the top of the column; The collection and cleaning mechanism is located at the top of the outer wall of the column.

[0007] Preferably, the top of the turntable has several arc-shaped holes along the circumference, and the upright is adapted to be inserted into one side of the inner cavity of the arc-shaped holes.

[0008] Preferably, the collection and cleaning mechanism includes: a limiting block, wherein a limiting groove is formed on the outer side of the top of the column, and limiting blocks are inserted into both the front and rear sides of the inner cavity of the limiting groove; a crossbar, wherein a crossbar is fixedly provided on the top of the limiting block; a push plate, which is fixedly provided on the outer side of the bottom end of the crossbar; a tray, which is fixedly provided on the top of the outer wall of the column, and the bottom end of the push plate contacts the top of the tray, wherein discharge holes are formed on the left and right sides of the top of the tray, and the discharge holes are located directly above the collection box; a conical cover, which is fixedly provided on the top of the outer wall of the column and located on the top of the tray; and a connecting ring, which is fixedly provided on the bottom end of the crossbar and is sleeved with the column.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the stator machining auxiliary fixture set; The auxiliary clamping mechanism of this utility model drives the first bevel gear and the second bevel gear to mesh and transmit power through a stepper motor, which drives the turntable to rotate. The arc-shaped hole on the turntable pushes the upright rod to move outward or inward synchronously along the slide groove of the support plate, thereby clamping or releasing the annular stator with different inner diameters. This effectively prevents the stator from shaking during processing, ensures processing accuracy, reduces the intensity of manual operation, and can accurately control the clamping force to avoid stator deformation or positioning failure. The equipped collection and cleaning mechanism guides the waste generated during processing onto a lower tray, preventing it from scattering to other parts of the equipment. The waste on the tray is then quickly pushed to the discharge port, where it falls directly into the collection box below for collection. This maintains a clean processing environment and reduces the impact of waste on subsequent processing steps. Attached Figure Description

[0015] Please see Figure 1-5 This utility model provides a technical solution: a stator processing auxiliary fixture set, including: a base 1, a column 2, a collection box 3, an auxiliary clamping mechanism 4, and a collection and cleaning mechanism 5; The column 2 is fixedly installed on the top of the base 1.

To clamp and fix the stator, a support plate 41 is fixedly installed at the top of the inner cavity of the column 2. Several grooves 43 are circumferentially formed at the top of the support plate 41. A slider 42 is inserted into the inner cavity of each groove 43. A vertical rod 44 is fixedly installed at the top of the slider 42. The vertical rod 44 can move along the direction of the groove 43 through the cooperation of the groove 43 and the slider 42. The inner cavity of the groove 43 is dovetail-shaped, and the slider 42 is fitted and inserted into the inner cavity of the groove 43. A through hole 45 is provided at the top of the column 2. The rod 44 extends out of the inner cavity of the through hole 45. A stop 46 is fixedly installed at the top of one side of the outer wall of the rod 44. A limiting plate 47 is fixedly installed on one side of the outer wall of the rod 44, and the limiting plate 47 is located below the stop 46. The stator is a ring-shaped part. After the stator part to be processed is passed through the stop 46 and fitted onto the outside of the rod 44, the stator can be supported by the limiting plate 47. By moving the rod 44 outward, the rod 44 can support and fix the stator, and the stop 46 can limit the top of the stator.

[0017] In order to drive the turntable 412 to move the upright 44, the rotating shaft 48 is rotatably mounted on the top of the support plate 41 via bearings. The bottom end of the rotating shaft 48 extends out of the bottom end of the support plate 41 and is keyed to a first bevel gear 49. The stepper motor 410 is fixedly mounted on one side of the outer wall of the column 2. The output end of the stepper motor 410 extends into the inner cavity of the column 2 and is keyed to a second bevel gear 411. The second bevel gear 411 meshes with the first bevel gear 49. Through the cooperation of the first bevel gear 49 and the second bevel gear 411, the stepper motor 410 can drive the rotating shaft 48 to rotate.

[0018] As a preferred option, the top of the turntable 412 is provided with several arc-shaped holes 413 along the circumference, and the upright 44 is adapted to be inserted into one side of the inner cavity of the arc-shaped holes 413. When the turntable 412 rotates, the inner wall of the arc-shaped holes 413 pushes the upright 44 to move outward.

[0019] As a preferred embodiment, the collection and cleaning mechanism 5 further includes: a limiting block 51, a limiting groove 52, a crossbar 53, a push plate 54, a tray 55, a discharge hole 56, and a conical cover 57. To facilitate the collection and cleaning of waste shavings from stator machining and grinding, a limiting groove 52 is provided on the outer side of the top of the column 2. Limiting blocks 51 are inserted into both the front and rear sides of the inner cavity of the limiting groove 52. A crossbar 53 is fixedly mounted on the top of the limiting block 51. A push plate 54 is fixedly mounted on the outer side of the bottom end of the crossbar 53. A tray 55 is fixedly mounted on the top of the outer wall of the column 2, with the bottom end of the push plate 54 contacting the top of the tray 55. Discharge holes 56 are provided on the left and right sides of the top of the tray 55, and the discharge holes 56 are located in the collection box 3. Directly above, push the crossbar 53 to drive the push plate 54 to rotate, thereby cleaning the waste on the tray 55, so that the waste is pushed into the discharge hole 56 and falls into the collection box 3 for collection. The conical cover 57 is fixedly installed on the top of the outer wall of the column 2 and located at the top of the tray 55. The connecting ring 58 is fixedly installed at the bottom of the crossbar 53 and is sleeved with the column 2. The connecting ring 58 is used to connect the front and rear crossbars 53 together, so that the crossbars 53 on both sides can be rotated synchronously.

[0020] As a preferred option, the inner cavity of the limiting groove 52 is T-shaped, and the limiting block 51 is fitted and inserted into the inner cavity of the limiting groove 52 to limit the limiting block 51 and prevent the limiting block 51 from detaching from the inner cavity of the limiting groove 52.

[0021] As a preferred option, the bottom end of the push plate 54 contacts the bottom end of the outer wall of the conical cover 57. By providing the conical cover 57, the material processed from the stator slides down the outer wall of the conical cover 57 into the moving cleaning range of the push plate 54 on the tray 55.

[0022] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0023] Step 1: First, pass the annular stator part to be processed through the stop 46 at the top of the upright 44 and fit it on the outside of the upright 44 until the bottom of the stator contacts the limiting plate 47 on the upright 44. The limiting plate 47 supports the stator. Start the stepper motor 410. The output end of the stepper motor 410 drives the second bevel gear 411 to rotate. Since the second bevel gear 411 meshes with the first bevel gear 49 at the bottom of the rotating shaft 48, it drives the rotating shaft 48 to rotate around the bearing on the support plate 41. The turntable 412 at the top of the rotating shaft 48 rotates synchronously with the rotating shaft 48. The arc-shaped hole 413 opened circumferentially at the top of the rotating shaft 48 is adapted to fit the upright 44. Next, when the turntable 412 rotates, the inner wall of the arc-shaped hole 413 exerts an outward pushing force on the upright rod 44 inserted in the hole, pushing the upright rod 44 to drive the slider 42 to move outward synchronously along the dovetail groove 43 on the support plate 41 until the outer wall of the upright rod 44 is tightly fitted with the inner wall of the stator, supporting and fixing the stator. At this time, the stop block 46 plays a limiting role on the top of the stator to prevent the stator from moving upward during the processing, thus completing the clamping of the stator. If the stator needs to be removed, simply control the stepper motor 410 to reverse, driving the turntable 412 to rotate in the opposite direction. The inner wall of the arc-shaped hole 413 pushes the upright rod 44 inward, and the upright rod 44 disengages from the inner wall of the stator, allowing the stator to be removed. Step 2: During the stator machining and grinding process, the generated metal scraps fall onto the conical cover 57. The inclined structure of the conical cover 57 causes the scraps to slide down its outer wall onto the tray 55 below, achieving initial collection of scraps. When the machining is completed or the scraps on the tray 55 accumulate to a certain amount, the crossbar 53 is pushed. The limiting block 51 at the bottom of the crossbar 53 slides along the "T"-shaped limiting groove 52 on the outer side of the top of the column. Since the connecting ring 58 connects the crossbars 53 on the front and rear sides into one piece, the crossbars 53 on both sides simultaneously drive the push plate 54 at the bottom to rotate along the surface of the tray. The bottom end of the push plate 54 is in close contact with the top of the tray 55, and one side is in contact with the bottom end of the outer wall of the conical cover 57. During the rotation, the push plate 54 pushes the scraps on the tray 55 toward the discharge holes 56 on the left and right sides of the tray 55. The scraps fall into the collection box 3 on the base 1 below through the discharge holes 56, completing the collection of scraps. The collection box 3 can be disassembled and cleaned periodically to achieve centralized processing of scraps.
