Description

Technical Field

[0001] The utility model relates to the field of motors for automotive fans, in particular to a clamping device for stator assembly. Background Art

[0002] An automotive radiator fan motor is used to drive the fan blades to rotate, so as to provide sufficient air volume to reduce the temperature of the engine compartment and ensure the safe driving of the vehicle. An automotive fan motor generally includes two parts: a stator and a rotor. During the processing of the stator, first, a winding machine is used to wind each stator block, then the stator blocks are fitted into a circle to form a stator semi-finished product, then the stator semi-finished product is installed on a stator bracket to form a stator finished product, and finally, the stator and the rotor are assembled to form the motor. When installing the stator semi-finished product on the stator bracket, first, it is necessary to manually pick and place or clamp the stator semi-finished product through a fixture, and then place it on the stator bracket for fixation. Manual picking and placing is inefficient and cannot meet the requirements of automated production; while existing fixtures all use the cooperation of a limiting mechanism arranged on the production line to clamp the stator semi-finished product, and they cannot limit the stator semi-finished product by themselves before clamping. The additional setting of a limiting mechanism on the production line complicates the production line and is also likely to damage the stator semi-finished product during the clamping process of the fixture, which is not conducive to production. Summary of the Utility Model

[0003] In view of the existing deficiencies, the utility model provides a clamping device for stator assembly.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a clamping device for stator assembly, including a three-axis moving mechanism capable of moving in the XYZ axes, and an R-axis displacement platform arranged on the three-axis moving mechanism and moving in the three axes of the three-axis moving mechanism; a jaw cylinder driven to rotate by the R-axis displacement platform is arranged on the R-axis displacement platform, and the jaws of the jaw cylinder are parallel jaws; a pressing member capable of moving up and down between the two jaws of the jaw cylinder is also arranged on the R-axis displacement platform.

[0005] Preferably, two lifting cylinders are correspondingly arranged at the positions on the opposite sides of the R-axis displacement platform, and the connection line between the two lifting cylinders is perpendicular to the connection line between the two jaws of the jaw cylinder; the pressing member is a pressing plate with a flat bottom surface, and the two ends of the top surface of the pressing member are correspondingly connected to the two lifting cylinders and driven to move up and down by the lifting cylinders.

[0006] Preferably, a vision detection mechanism located in front of the R-axis displacement platform and moving in the three axes of the three-axis moving mechanism is also arranged on the three-axis moving mechanism.

[0007] Preferably, the three-axis moving mechanism includes two horizontal guide rails in the X-axis direction arranged in parallel at intervals, a sliding seat with both ends slidably arranged on the two horizontal guide rails, a first slider slidably arranged on the sliding seat in the Y-axis direction, and a second slider slidably arranged on the first slider in the Z-axis direction. The R-axis displacement platform is installed on the second slider.

[0008] Preferably, a mounting seat is fixedly installed on the second slider, and the R-axis displacement platform is installed on the mounting seat.

[0009] Preferably, an anti-slip pad is arranged on the jaw of the jaw cylinder.

[0010] The beneficial effects of the present utility model are as follows: The present utility model combines the pressing member with the jaw cylinder, uses the pressing member to press on the semi-finished stator to be clamped for limiting, and then the jaw cylinder clamps. There is no need to set an additional limiting mechanism on the production line, which simplifies the setting of the production line; at the same time, the pressing member and the jaw cylinder can move synchronously through the three-axis moving mechanism and the R-axis displacement platform. During the clamping of the semi-finished stator, the pressing member only abuts against the semi-finished stator. When the jaw cylinder clamps the semi-finished stator and moves it to the next process, there is no need to take it out from the limiting mechanism, and it can be directly moved to the next process, avoiding damage caused by the friction of the limiting mechanism to the semi-finished stator.

The directional terms used are for better and clearer illustration and understanding of the present invention, rather than indicating or implying the orientation that the present invention must have. Therefore, it cannot be understood as a limitation to the present invention.

[0015] Embodiments of the present invention, such as Figure 1 and Figure 2As shown in the figure, a clamping device for stator assembly includes a three-axis moving mechanism 1 capable of moving in the X, Y, and Z axes. The three-axis moving mechanism 1 is a mechanism that can move in the X-axis, Y-axis, and Z-axis directions to meet the requirements of moving in different directions. During use, the three-axis moving mechanism 1 is set on the operation table of the production line. The three-axis moving mechanism 1 includes two horizontal guide rails 10 in the X-axis direction arranged side by side at intervals, a sliding seat 11 with both ends sliding correspondingly on the two horizontal guide rails 10, a first slider 12 sliding on the sliding seat 11 in the Y-axis direction, and a second slider 13 sliding on the first slider 12 in the Z-axis direction; on the production line, one end of the horizontal guide rail 10 is arranged corresponding to the incoming material conveying end for conveying the stator semi-finished product 7, and the other end is arranged corresponding to the incoming material output end of the stator bracket, so that it is convenient to clamp the incoming stator semi-finished product 7 and convey it from one end of the horizontal guide rail 10 to the stator bracket at the other end for assembly with the stator bracket; the sliding seat 11 is installed on the guide rail slider of the horizontal guide rail 10 itself, and its sliding power comes from the drive of the first cylinder arranged corresponding to any one of the horizontal guide rails 10. Installation brackets are provided at the bottoms of the two horizontal guide rails 10, and the first cylinder is arranged on the installation bracket of any one of the horizontal guide rails 10, and this horizontal guide rail 10 forms the main power slide rail, and the other horizontal guide rail 10 forms the guiding slide rail; the first slider 12 slides on the sliding seat 11 in the Y-axis direction, and the first slider 12 can move in the X-axis direction along with the sliding seat 11. At this time, sliding tracks and clamping grooves that can cooperate with each other in sliding are provided between the first slider 12 and the sliding seat 11, and its sliding power comes from the drive of the second cylinder arranged on the sliding seat 11; the second slider 13 can slide in the X-axis direction along with the sliding seat 11, slide in the Y-axis direction along with the first slider 12, and at the same time can slide on the first slider 12 in the Z-axis direction, so that the second slider 13 can be moved to the required position through movement in different directions. The sliding between the second slider 13 and the first slider 12 is also provided with sliding tracks and clamping grooves that can cooperate with each other in sliding, and its sliding power comes from the drive of the third cylinder arranged on the first slider 12; a rotatable R-axis displacement platform 2 capable of three-axis movement is provided on the three-axis moving mechanism 1. After the R-axis displacement platform 2 is moved to a suitable position through the three-axis moving mechanism 1, the corresponding angle is adjusted through the R-axis displacement platform 2 for convenient clamping. The R-axis displacement platform 2 is installed on the second slider 13. As the second slider 13 moves and adjusts its position in different directions, at the same time it can also perform rotational adjustment. In this way, after it moves to a determined position along with the second slider 13, it can adjust the angle it is in through its own rotation for convenient use; an installation seat 20 is fixedly installed on the second slider 13, and the R-axis displacement platform 2 is installed on the installation seat 20, so that the structure of the second slider 13 can be simplified and it is convenient to install the R-axis displacement platform 2 on the second slider 13;On the R-axis displacement platform 2, there is a jaw cylinder 3 driven by the rotation of the R-axis displacement platform 2. The jaws of the jaw cylinder 3 are parallel jaws. The jaw cylinder 3 can adjust its position in different directions and adjust its angle through the R-axis displacement platform 2, which is convenient for clamping the stator semi-finished product 7. When using the parallel jaws to clamp the stator semi-finished product 7, the jaws clamp it in a manner parallel to the outer wall of the stator semi-finished product 7, thus avoiding damaging the stator semi-finished product 7. On the R-axis displacement platform 2, there is also a pressing member 4 that can move up and down between the two jaws of the jaw cylinder 3, which means that after the two jaws of the jaw cylinder 3 clamp the stator semi-finished product 7, the pressing member 4 is above the stator semi-finished product 7. When using this clamping device to clamp the stator semi-finished product 7, first move the R-axis displacement platform 2 to directly above the stator semi-finished product 7, then adjust the angle of the jaw cylinder 3 so that its jaws are aligned with the angle of the position to be clamped on the stator semi-finished product 7. After that, the pressing member 4 moves downward and presses against the top of the stator semi-finished product 7 to limit its position. Finally, the jaws of the jaw cylinder 3 close to clamp the stator semi-finished product 7 and move it to the position of the stator bracket. At this position, the jaw cylinder 3 moves downward to align the stator semi-finished product 7 and place it on the stator bracket and then releases the jaws. At this time, the pressing member 4 can move downward to exert a downward pressure on the stator semi-finished product 7 so as to press the stator semi-finished product 7 into the stator bracket, which is convenient for the next process.

[0016] For further improvement, as Figure 2 shown in, two lifting cylinders 5 are correspondingly arranged at the corresponding positions on the opposite sides of the R-axis displacement platform 2. The connection line between the two lifting cylinders 5 is perpendicular to the connection line between the two jaws of the jaw cylinder 3. The pressing member 4 is a pressing plate with a flat bottom surface. The two ends of the top surface of the pressing member 4 are correspondingly connected to the two lifting cylinders 5 and are driven to move up and down by the lifting cylinders 5, that is, the two lifting cylinders 5 and the two jaws of the jaw cylinder 3 are at the four equal division points of the rotation circumference of the R-axis displacement platform 2, which will neither affect the clamping of the jaw cylinder 3 nor affect the lifting of the pressing member 4. The flat bottom surface of the pressing member 4 can exert a uniform and stable pressure on the stator semi-finished product 7 when it presses on the stator semi-finished product 7 and will not damage it.

[0017] For further improvement, as Figure 1 and Figure 2 shown in, a vision detection mechanism 6 that can move in three axes is also arranged on the three-axis moving mechanism 1 and is located in front of the R-axis displacement platform 2. The vision detection mechanism 6 uses an industrial CCD camera to detect the position of the stator semi-finished product 7 to be clamped through it, and then adjust the position of the jaw cylinder 3. It is installed on the second slider 13 of the three-axis moving mechanism 1 through a bracket. When the R-axis displacement platform 2 is installed on the second slider 13 through the mounting seat 20, the vision detection mechanism 6 is installed on the side of the mounting seat 20 away from the second slider 13.

[0018] For further improvement, an anti-slip pad (not shown in the figure) is provided on the jaws of the jaw cylinder 3. The setting of the anti-slip pad increases the clamping surface area of the jaw cylinder 3 on the semi-finished stator 7, ensuring the stability of clamping.

[0019] Although the present utility model has been described in detail with general descriptions and specific embodiments above, based on the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
