Description

Technical Field

[0001] The invention relates to the technical field of motor stator processing, in particular to a motor stator cavity clearing and gate removal device. Background Art

[0002] Motor stator cavity cleaning and de-gating refers to the operation of de-gating and cleaning the inner cavity of the stator during the motor stator production process, ensuring that the plastic in the stator cavity is cleaned without residue, so that the internal metal body is completely exposed to the outside, improving the quality of subsequent assembly.

[0003] However, conventional cavity cleaning equipment uses elastic brushes, which prevent the brush diameter from maintaining a constant size and instead change with use, making high-precision cleaning impossible. To ensure that the plastic is cleaned without damaging the metal, manual control is required during cavity cleaning, making it difficult to improve cleaning accuracy and efficiency.

[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a motor stator cavity cleaning and gate removal device to solve the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solution of the present invention and facilitating the understanding of those skilled in the art. It cannot be assumed that the above contents are well known to those skilled in the art simply because they are explained in the background technology of the present invention. Summary of the Invention

[0006] In order to overcome the above-mentioned deficiencies in the prior art, the present invention aims to disclose a motor stator cavity cleaning and gate removal device for automatically cleaning the gate and inner cavity of the motor stator.

[0007] The present invention discloses a motor stator cavity cleaning and gate removal device, comprising a processing table, wherein a turntable capable of rotating in a horizontal direction is provided on the processing table; a loading and unloading unit, a polishing unit, a gate milling unit, and an oiling unit are sequentially provided on the outer side of the turntable along the circumferential direction, wherein:

[0008] At least one stator processing seat is installed on the turntable for circumferential rotation. A driving motor is connected to the lower part of the stator processing seat, and a top limiting mechanism is provided above the positioning processing seat for lifting and lowering.

[0009] The stator workpiece is loaded and unloaded on the stator processing seat at the loading and unloading unit;

[0010] A first moving component is provided at the polishing unit, and the output end of the first moving component is connected to the polishing component. The first moving component can drive the polishing component to perform horizontal and lifting movements; the output end of the polishing component can pass through the lower end of the stator processing seat to polish the inner cavity of the stator workpiece thereon, and the output end of the polishing component is connected to a torque sensor; when the polishing component polishes the inner cavity of the stator workpiece, the torque generated when its output end contacts plastic and metal is significantly different. Through the feedback of the torque by the torque sensor, the polishing component can automatically judge and control the degree of polishing of the inner cavity of the stator workpiece.

[0011] A second moving assembly is provided at the milling gate unit, and an output end of the second moving assembly is connected to a milling cutter mechanism. The output end of the milling cutter mechanism is provided with a milling cutter for processing the stator workpiece gate along the vertical direction.

[0012] The oiling unit is provided with a first lifting mechanism, and the output end of the first lifting mechanism is provided with a spraying mechanism. The output end of the spraying mechanism can pass through the lower end of the stator processing seat to oil the inner cavity of the stator workpiece thereon.

[0013] A preferred technical solution: A second lifting mechanism is also provided at the gate milling unit. A cleaning nozzle is located at the output end of the second lifting mechanism. The cleaning nozzle passes through the lower end of the stator processing seat to clean the internal cavity of the stator workpiece. The cleaning nozzle can spray cleaning liquid or compressed gas to clean and dry the internal cavity of the stator workpiece.

[0014] Preferred technical solution: The cleaning nozzle is a high-speed rotating nozzle to avoid incomplete cleaning due to local blockage of the nozzle during the cleaning process.

[0015] The preferred technical solution: A driven gear is mounted on the outer periphery of the stator processing seat. One side of the driven gear meshes with a transmission gear, which is rotatably connected to the turntable. A drive motor is mounted on the processing table and can be raised and lowered. The output end of the drive motor connects to the lower end of the transmission gear for transmission. Using an external drive at the stator processing seat reduces the number of devices on the turntable and improves its smooth operation.

[0016] The preferred technical solution: The top limit mechanism includes a mounting frame mounted on the processing table. The mounting frame is equipped with a third lifting mechanism above the operating path of the stator processing seat. The third lifting mechanism is equipped with a pressure head assembly. The third lifting mechanism can control the pressure head assembly to press the stator workpiece on the stator processing seat, preventing the stator workpiece from moving up and down during processing. The front end of the pressure head assembly is rotatably connected to a limit pressure ring for vertically limiting the stator workpiece on the stator processing seat. The rotatable connection of the limit pressure ring prevents the pressure head assembly from obstructing the horizontal rotation of the stator workpiece.

[0017] Preferred technical solution: the loading and unloading unit, the polishing unit, the sprue milling unit and the oiling unit are all provided with positioning photoelectric devices for positioning the stator processing seat.

[0018] Preferred technical solution: A receiving tray is further provided on the lower side of the stator processing seat for receiving debris generated during the processing.

[0019] Preferred technical solution: The stator processing seat is provided with a clamping groove for limiting the circumferential direction of the stator workpiece, which is used to drive the stator workpiece to rotate together with the stator processing seat.

[0020] Due to the application of the above technical solution, the motor stator cavity cleaning and de-gating device of the present invention has the following beneficial effects:

[0021] (1) By measuring the difference in torque between plastic and metal polishing at the polishing output end, the polishing component can automatically judge the polishing degree of the inner cavity of the stator workpiece without manual adjustment, thereby improving the polishing accuracy and efficiency.

[0022] (2) The self-rotation processing method of the stator processing seat is adopted to reduce the displacement of the equipment during processing, while improving the stability of the stator workpiece processing movement, thereby improving the consistency of the stator workpiece processing accuracy.

[0023] (3) A nozzle is used to clean and oil the inner cavity of the stator workpiece, which improves the processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The mounting frame 13a is provided with a third lifting mechanism 13b above the operating track of the stator processing seat 11. The third lifting mechanism 13b is provided with a pressure head assembly 13c. The front end of the pressure head assembly 13c is rotatably connected to a limiting pressure ring 13d for vertically limiting the stator workpiece on the stator processing seat 11; a material receiving tray 11c is also provided on the lower side of the stator processing seat 11; and a clamping groove 11d for circumferentially limiting the stator workpiece is provided on the stator processing seat 11.

[0038] like Figure 1 and Figure 4 As shown, a first moving component 31 is provided at the polishing unit 3, and the output end of the first moving component 31 is connected to the polishing component 32. The output end of the polishing component 32 can pass through the lower end of the stator processing seat 11 to perform inner cavity polishing of the stator workpiece thereon, and the output end of the polishing component 32 is connected to a torque sensor.

[0039] like Figure 1 、 Figure 5 and Figure 6 As shown, a second moving assembly 41 is provided at the milling gate unit 4, and the output end of the second moving assembly 41 is connected to a milling cutter mechanism 42. The output end of the milling cutter mechanism 42 is provided with a milling cutter 42a for processing the gate of the stator workpiece in the vertical direction; a second lifting mechanism 43 is also provided at the milling gate unit 4, and the output end of the second lifting mechanism 43 is provided with a cleaning nozzle 44.

[0041] like Figure 1As shown, the loading and unloading unit 2 , the polishing unit 3 , the gate milling unit 4 and the oiling unit 5 are all provided with positioning photoelectric devices 6 for positioning the stator processing seat 11 .

[0042] refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the principle of the motor stator cavity clearing and de-gating device of the present invention is as follows: During use, the stator processing seat 11 at the loading and unloading unit 2 is loaded. It should be noted that in some embodiments, a protective photoelectric device is provided at the loading unit 2 to prevent the operation of the device from causing harm to the operator or the robot during the loading and unloading process. After the stator workpiece is placed on the stator processing seat 11, the turntable 1 rotates to drive the stator processing seat 11 and the stator workpiece thereon to the polishing unit 3. During this process, the turntable 1 is positionally corrected using the positioning photoelectric device 6. Then, the third lifting mechanism 13b drives the pressure head assembly 13c to press and lock the stator workpiece. The drive motor 12 drives the positioning processing seat 11 to rotate. The first moving component 31 drives the polishing component 32 to move, so that the output end of the polishing component 32 passes through the lower end of the stator processing seat 11 to polish the inner cavity of the stator workpiece thereon. During this process, the first moving component 31 adjusts the position of the polishing component 32 according to the torque information fed back by the torque sensor, so that the plastic in the inner cavity of the stator workpiece is polished cleanly without damaging the metal body. The principle here is further explained as follows: during the polishing process, the positioning processing seat 11 drives the stator workpiece to rotate, and the output end brush head of the polishing component 32 rotates and presses toward one side of the inner cavity of the stator workpiece to remove the plastic in the inner cavity of the stator workpiece. When the brush head contacts the metal body, the torque sensor feeds back data to the control terminal to control the polishing component 32 to avoid damage to the metal body. When the inner cavity of the stator workpiece is polished, the turntable 1 drives the positioning processing seat 11 to move to the milling gate unit 4, where the top limit mechanism 13 again limits the stator workpiece on the stator processing seat 11, and the drive motor 12 at the milling gate unit 4 rotates and drives the stator processing seat 11; the second moving component 41 controls the milling cutter mechanism 42 to clean the gate of the stator workpiece, and at the same time, the second lifting mechanism 43 drives the cleaning nozzle 44 to pass through the lower end of the stator processing seat 11 to clean the inner cavity of the stator workpiece thereon; after the stator workpiece is processed at the milling gate unit 4, the turntable 1 drives the stator processing seat 11 and the stator workpiece thereon to enter the oiling unit 5, driven by the drive motor 12 here, and driven by the first lifting mechanism 51 to drive the spraying mechanism 52, pass through the lower end of the stator processing seat 11 to oil the inner cavity of the stator workpiece thereon; the stator workpiece after processing is brought to the loading and unloading unit 2 by the turntable for unloading.
