[0018] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0020] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0021] like Figures 1 to 3 As shown, the four-axis cutting device for motor impellers of this utility model includes: a frame 1 with a processing station for cutting the impeller, a carrier plate 2 for placing the impeller is rotatably mounted on the processing station, a two-axis linear module 3 is provided on the side of the processing station of the frame 1, the two-axis linear module 3 is used to control the laser cutting head 4 to move along the X-axis or Z-axis direction; a Y-axis linear module 5 is provided at the processing station of the frame 1, and is used to drive the carrier plate 2 to move along the Y-axis direction; a fixing clamp 6 is provided on the top surface of the carrier plate 2 and is coaxial with the carrier plate 2, the fixing clamp 6 is used to support and fix the impeller.
[0022] See Figures 1 to 3 The two-axis linear module 3 consists of at least an X-axis linear module and a Z-axis linear module. The Z-axis linear module is driven to move along the X-axis direction by the X-axis linear module. The laser cutting head 4 is mounted on the Z-axis linear module and is driven to move along the Z-axis direction by the Z-axis linear module. The Y-axis linear module 5 is mounted on the processing station of the frame 1 to drive the carrier plate 2 to move along the Y-axis direction. The carrier plate 2 is rotatably mounted on the Y-axis linear module 5 and configured to rotate. A fixing clamp 6 is mounted on the carrier plate 2. The fixing clamp 6 can clamp the inner side of the motor impeller placed on the carrier plate 2 to ensure the stability of the motor impeller when rotating.
[0023] Specifically, when performing circumferential cutting on the outer circumference of the motor impeller, the Y-axis linear module 5 first drives the carrier plate 2 to move out of the processing position of the frame 1, clamps the impeller to be processed onto the carrier plate 2, and uses the fixing fixture 6 to fasten the impeller. Then, the Y-axis linear module 5 moves the carrier plate 2 back to the processing position of the frame 1. After the laser cutting head 4 is in position controlled by the two-axis linear module 3, the carrier plate 2 is controlled to rotate at a uniform speed, so that the laser cutting head 4 can perform laser cutting on the outer circumference of the impeller. This method has the characteristics of high impeller cutting efficiency and high impeller processing accuracy, and is practical.
[0024] In one or more embodiments, the fixing clamp 6 includes an outer sleeve 61 fixedly disposed in the middle of the carrier plate 2, a fixing member 62 fixedly disposed in the outer sleeve 61, and a conical member 63 slidably disposed in the outer sleeve 61 below the fixing member 62. The outer surface of the conical member 63 has a first conical surface 631, and the bottom of the fixing member 62 is recessed and has a second conical surface 621 adapted to the first conical surface 631. The fixing member 62 has at least two limiting holes through it in the radial direction. A limiting rod 64 is slidably installed in the limiting holes. The limiting rod 64 is mounted on the fixing member 62 by means of an elastic member 65. One end of the limiting rod 64 is at least partially located in the second conical surface 621 of the fixing member 62.
[0025] See Figure 1 , Figure 3 The fixing member 62 and the conical member 63 are arranged vertically from top to bottom inside the outer sleeve 61. The height of the fixing member 62 inside the outer sleeve 61 is relatively fixed. The conical member 63 can move vertically inside the outer sleeve 61. The outer sleeve 61, the fixing member 62 and the conical member 63 are coaxial with the carrier plate 2. The bottom surface of the fixing member 62 is concave to form a second conical surface 621. The outer surface of the conical member 63 has a first conical surface 631. The first conical surface 631 and the second conical surface 621 are adapted to each other so that after the conical member 63 rises to a predetermined height, the first conical surface 631 of the conical member 63 can fit into the second conical surface 621 of the fixing member 62.
[0026] See Figure 3 The fixing member 62 has at least two sets of limiting holes extending through it in the radial direction. A limiting rod 64 is movably installed in the limiting holes. The outer sleeve 61 also has a through hole corresponding to the position of the limiting hole. The limiting rod 64 can extend out of the outer sleeve 61 through the through hole. The fixing member 62 has a relief groove. An elastic member 65 is installed in the relief groove. The other end of the elastic member 65 is connected to the limiting rod 64. It should be noted that when the conical member 63 does not enter the bottom of the fixing member 62, under the action of the elastic member 65, the end of the limiting rod 64 extends into the recess of the fixing member 62.
[0027] When fixing the impeller to the carrier plate 2, first place the impeller on the carrier plate 2 so that the outer sleeve 61 is inside the impeller. Then, lift the conical member 63 vertically upwards, so that the conical member 63 pushes the limiting rod 64 out of the outer sleeve 61 to abut against the inner wall of the impeller. This method has the characteristics of simple structure, high fixing strength, and practicality. After the impeller is cut, control the conical member 63 to move downwards so that the conical member 63 is no longer abutting against the limiting rod 64. Under the action of the elastic member 65, the end of the limiting rod 64 retracts into the limiting hole. At this time, the impeller is no longer abutted by the limiting rod 64, and the impeller can be removed using a robot.
[0028] In one or more embodiments, a waste collection assembly is also included. The waste collection assembly is located at the processing station of the frame 1 and is used to collect the impeller waste cut by the laser cutting head 4. The waste collection assembly includes a bracket and an annular profiler mounted on the bracket. An electromagnet is rotatably mounted on the bottom surface of the annular profiler. The profiler is configured on the bracket to be able to rise and fall in the vertical direction.
[0029] The attached diagram does not show the waste collection assembly. When the carrier plate 2 and the impeller on the carrier plate 2 are transported to the processing station by the Y-axis linear module 5, the annular profiler is located directly above the impeller. When the laser cutting head 4 cuts off the excess material on the outer circumference of the top of the impeller, the electromagnet can attract the waste material. At the same time, since the electromagnet is installed at the bottom of the profiler by means of the ball bearing, the electromagnet can rotate synchronously with the impeller while attracting the waste material, so as to ensure the stability of the laser cutting head 4 in cutting the impeller, and at the same time, it can realize the rapid collection of waste material.
[0030] In one or more embodiments, the carrier disk 2 is driven to rotate by a first drive device mounted on the Y-axis linear module 5; a second drive device is mounted on the carrier disk 2, and the tapered member 63 is controlled by the second drive device to move closer to or away from the fixed member 62.
[0031] See Figure 1 The first driving device can be a servo motor or a rotary cylinder, and the second driving device can be a drive cylinder. The types of the first and second driving devices are not specifically limited, as long as they can make the carrier plate 2 rotate circumferentially and make the conical part 63 move in the vertical direction.
[0032] In one or more embodiments, a third drive device 7 is installed at the control end of the two-axis linear module 3. The third drive device 7 is used to control the rotation of the laser cutting head 4 along the Y-axis direction. See also Figure 2 The third drive unit 7 is installed on the Z-axis linear module. The third drive unit 7 can be a servo motor or a rotary cylinder.
[0033] In one or more embodiments, the frame 1 is provided with a baffle 8 on the side of the processing station.
[0034] See Figure 1 When the laser cutting head 4 cuts the impeller, it will generate sparks. The baffle 8 can block the sparks, which can improve the safety of cutting the impeller.
[0035] In one or more embodiments, the elastic element 65 is a spring or elasticity.
[0036] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
