Description

Technical Field

[0001] This utility model relates to the field of water pump assembly technology, and in particular to a rotor assembly device for automotive water pumps. Background Technology

[0002] In the field of new energy vehicles, electric water pumps, through circulating coolant, can construct an efficient thermal management system, thereby providing efficient heat dissipation for the drive motor, motor controller, and power battery of new energy vehicles. The structure of an electric water pump typically includes a housing, inside which a stator, rotor, and impeller are installed; when the stator is energized, it generates a rotating magnetic field, which drives the rotor, made of permanent magnets, to rotate the impeller, thus providing power for the circulation of coolant.

[0003] In existing technologies, the assembly of the rotor in an electronic water pump mainly relies on operators' experience to manually assemble the rotor into the stator and housing. However, due to the rotor's inherent magnetic force, it is difficult for operators to precisely control the rotor's movement and placement during manual assembly. This can easily lead to the rotor scraping against the stator and housing, causing product damage, affecting product quality, and failing to meet the stringent requirements of the new energy vehicle industry for high quality and high reliability. Utility Model Content

[0004] Therefore, it is necessary to provide a rotor assembly device for automotive water pumps to address the problems of low assembly efficiency, poor assembly quality and consistency, and difficulty in meeting the high quality and high reliability requirements of the new energy vehicle industry in the existing manual rotor assembly technology.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A rotor assembly device for an automotive water pump includes a workpiece carrier on which a rotor and a housing assembly are respectively supported. A transfer mechanism is arranged above the workpiece carrier in the vertical direction, and a lifting and positioning mechanism is arranged below the workpiece carrier. The working end of the lifting and positioning mechanism extends out to position the housing assembly on the workpiece carrier. A clamping mechanism is arranged on one side of the workpiece carrier to clamp the housing assembly on the workpiece carrier.

[0007] The rotor is picked up from the workpiece carrier by the transfer mechanism and transported horizontally to the top of the housing assembly. Then, the rotor is driven to make a downward linear motion in the vertical direction, thereby assembling the rotor into the housing assembly.

[0008] As a further improvement to the above technical solution:

[0009] The lifting and positioning mechanism comprises a lifting cylinder, the output end of which is connected to a positioning column. The lifting cylinder drives the positioning column to move in a vertical direction, thereby inserting the positioning column into the shaft hole of the housing assembly and positioning the housing assembly.

[0010] The bottom of the workpiece carrier is fixed with a guide sleeve, and a positioning post is installed inside the guide sleeve to guide the linear movement of the positioning post in the vertical direction.

[0011] The clamping mechanism is structured as follows: it includes a rotary clamping cylinder, the output end of which is connected to a pressure plate. The rotary clamping cylinder drives the pressure plate to rotate, thereby aligning the pressure plate with the housing assembly on the workpiece carrier. The rotary clamping cylinder also drives the pressure plate to move in a vertical downward linear motion, thereby pressing the pressure plate against the housing assembly on the workpiece carrier.

[0012] The workpiece carrier has the following structure: it includes a carrier plate, on which a rotor placement seat and a housing placement seat are respectively installed. The housing placement seat is provided with several positioning pins, which are used to initially position the housing assembly.

[0013] The transfer mechanism comprises: a first servo module arranged horizontally, the output end of the first servo module connected to a movable base, a second servo module arranged vertically fixed on the movable base, the output end of the second servo module connected to a floating stage cylinder, the output end of the floating stage cylinder connected to a power chuck, the output end of the power chuck connected to a gripper assembly, and the power chuck driving the gripper assembly to grip the rotor on the workpiece carrier;

[0014] The first servo module drives the moving seat to move in a straight line in the horizontal direction, thereby moving the gripper assembly to directly above the rotor on the workpiece carrier. The second servo module drives the gripper assembly to move in a straight line downward in the vertical direction, thereby gripping the rotor on the workpiece carrier.

[0015] The first servo module drives the moving seat to move in a straight line in the horizontal direction, thereby driving the rotor to move directly above the housing assembly on the workpiece carrier via the gripper assembly. The second servo module drives the gripper assembly to move in a straight line in the vertical direction, thereby driving the rotor down into the mounting hole of the housing assembly. The floating table cylinder drives the gripper assembly to press down, thereby installing the rotor into the housing assembly.

[0016] The gripper assembly includes at least three grippers, and the working end face of each gripper is provided with a concave arc surface.

[0017] The lifting and positioning mechanism, the clamping mechanism, and the workpiece carrier are all supported by mounting bases.

[0018] A support frame is fixed to the top of the mounting base, and the support frame is used to support the transfer mechanism.

[0019] A material box is fitted onto the top of the mounting base.

[0020] The beneficial effects of this utility model are as follows:

[0021] This utility model has a compact and reasonable structure and is easy to operate. By setting up a lifting and positioning mechanism, a clamping mechanism, a workpiece carrier, and a transfer mechanism, it can automatically complete the assembly between the rotor and the housing assembly, effectively improving assembly efficiency and reducing labor costs. At the same time, the lifting and positioning mechanism and the clamping mechanism can prevent the housing assembly from shifting during the assembly process, thereby ensuring assembly quality and consistency. The assembled product can meet the requirements of the new energy vehicle industry for high quality and high reliability.

[0022] This utility model also has the following advantages:

[0023] (1) In this utility model, by setting a positioning post, which cooperates with the shaft hole on the insertion housing, the center of the stator can be quickly positioned, thereby achieving precise positioning and centering; at the same time, it can prevent the housing components from shifting during assembly, ensuring assembly quality and consistency.

[0024] (2) By setting a guide sleeve, the vertical movement of the positioning column can be accurately guided, thereby reducing the movement deviation of the positioning column, ensuring that the positioning column 102 is accurately inserted into the shaft hole, and improving the positioning reliability.

[0025] (3) By setting a pressure plate, the shell can be pressed down from the top of the shell during the assembly process, thereby preventing the shell from shaking during the assembly process.

[0026] (4) By setting a positioning pin, the housing can be positioned during the process of placing the housing assembly on the workpiece carrier.

[0027] (5) In this utility model, by setting up a first servo module and a second servo module arranged perpendicularly to each other, the gripper assembly can drive the rotor to move in a straight line in the horizontal and vertical directions respectively, thereby achieving efficient and accurate assembly.

[0028] (6) In this utility model, by setting a gripper and setting an inward concave arc surface on the gripper that corresponds to the shape of the outer circle of the rotating shaft, the stability of the gripper assembly in gripping the rotor can be improved, and the rotor can be stably gripped.

[0029] (7) By setting a floating table cylinder in this utility model, it is possible to achieve fine vertical movement, ensuring that the rotor shaft can be accurately inserted into the shaft hole of the housing, ensuring stable and proper pressing, and improving the assembly quality.

[0043] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0044] The structure and function of this utility model are as follows:

[0045] like Figures 1-8 As shown, a rotor assembly device for an automotive water pump includes a workpiece carrier 3, on which a rotor 8 and a housing assembly are respectively supported. A transfer mechanism 5 is arranged above the workpiece carrier 3 in the vertical direction, and a lifting and positioning mechanism 1 is arranged below the workpiece carrier 3. The working end of the lifting and positioning mechanism 1 extends out to position the housing assembly on the workpiece carrier 3. A clamping mechanism 2 is arranged on one side of the workpiece carrier 3 to clamp the housing assembly on the workpiece carrier 3. The transfer mechanism 5 clamps the rotor 8 on the workpiece carrier 3 and drives the rotor 8 to be transported horizontally to the top of the housing assembly. Then, the rotor 8 is driven to make a downward linear motion in the vertical direction, thereby assembling the rotor 8 into the housing assembly. By setting up the workpiece carrier 3 and the transfer mechanism 5, the assembly between the rotor 8 and the housing assembly can be completed automatically, effectively improving assembly efficiency and reducing labor costs. At the same time, by setting up the lifting and positioning mechanism 1 and the clamping mechanism 2, the housing assembly can be prevented from shifting during the assembly process, thereby ensuring assembly quality and consistency. The assembled product can meet the requirements of the new energy vehicle industry for high quality and high reliability.

[0046] In this utility model, such as Figure 1 , Figures 7-8 As shown, the housing assembly includes a housing 9, which has mounting holes, and a stator 10 is installed in the mounting holes. When the housing assembly is assembled with the rotor 8, it is necessary to ensure that the rotor 8 and the stator 10 are assembled concentrically. In addition, a shaft hole is provided at the bottom of the housing 9 for engaging with the rotating shaft of the rotor 8.

[0047] like Figure 3 As shown, the lifting and positioning mechanism 1 has the following structure: it includes a lifting cylinder 101, the output end of which is connected to a positioning pin 102. The lifting cylinder 101 drives the positioning pin 102 to move vertically upwards, thereby inserting the positioning pin 102 into the shaft hole of the housing assembly, thus positioning the housing assembly. By setting the positioning pin 102, which cooperates with the shaft hole inserted into the housing 9, the center of the stator 10 can be quickly positioned, thereby achieving precise positioning and centering; at the same time, it can prevent the housing assembly from shifting during assembly, ensuring assembly quality and consistency.

[0048] The bottom of the workpiece carrier 3 is fixed with a guide sleeve 105, and a positioning pin 102 is installed inside the guide sleeve 105 to guide the linear movement of the positioning pin 102 in the vertical direction. By setting the guide sleeve 105, precise guidance can be provided for the vertical movement of the positioning pin 102, thereby reducing the movement deviation of the positioning pin 102, ensuring that the positioning pin 102 is accurately inserted into the shaft hole, and improving the positioning reliability.

[0049] like Figure 2 As shown, the clamping mechanism 2 has the following structure: it includes a rotary clamping cylinder 201, the output end of which is connected to a pressure plate 202. The rotary clamping cylinder 201 drives the pressure plate 202 to rotate, thereby aligning the pressure plate 202 with the housing assembly on the workpiece carrier 3. The rotary clamping cylinder 201 also drives the pressure plate 202 to move downwards in a vertical direction, thereby pressing the pressure plate 202 against the housing assembly on the workpiece carrier 3. The rotary clamping cylinder 201 can output torque and linear thrust, thereby realizing the rotary alignment and downward clamping movement of the pressure plate 202. By setting the pressure plate 202, the housing 9 can be pressed down from the top during assembly, thus preventing the housing 9 from shaking during assembly.

[0050] like Figure 2 As shown, the structure of the workpiece carrier 3 is as follows: it includes a carrier disk 303, on which a rotor placement seat 301 and a housing placement seat 302 are respectively installed. Several positioning pins 304 are provided on the housing placement seat 302, and the housing assembly is initially positioned by the positioning pins 304. A limiting hole is provided on the top of the rotor placement seat 301, which cooperates with the rotating shaft of the rotor 8 to achieve stable support of the rotor 8 by the rotor placement seat 301; a positioning groove is provided on the top of the housing placement seat 302, which limits the housing 9 to achieve stable support of the housing assembly by the housing placement seat 302; a through hole 305 is provided in the positioning groove, which corresponds to the shaft hole on the housing 9 to facilitate the positioning pin 102 to extend into the shaft hole through the through hole 305; by providing a positioning pin 304, which corresponds one-to-one with several positioning holes provided on the outer wall of the housing 9, the positioning pin 304 passes through the corresponding positioning hole to achieve positioning of the housing 9 during the process of placing the housing assembly on the workpiece carrier 3.

[0051] like Figures 4-6As shown, the transfer mechanism 5 has the following structure: it includes a first servo module 501 arranged horizontally, the output end of the first servo module 501 connected to a movable base 505, a second servo module 502 arranged vertically fixed on the movable base 505, the output end of the second servo module 502 connected to a floating table cylinder 506, the output end of the floating table cylinder 506 connected to a power chuck 507, and the output end of the power chuck 507 connected to a gripper assembly. The power chuck 507 drives the gripper assembly to grip the rotor 8 on the workpiece carrier 3; the first servo module 501 drives the movable base 505 to move linearly in the horizontal direction, thereby driving the gripper assembly to move to... Above the rotor 8 on the workpiece carrier 3, the second servo module 502 drives the gripper assembly to descend vertically, thereby gripping the rotor 8 on the workpiece carrier 3. The first servo module 501 drives the moving seat 505 to move horizontally, causing the gripper assembly to move the rotor 8 to directly above the housing assembly on the workpiece carrier 3. The second servo module 502 then drives the gripper assembly to descend vertically, lowering the rotor 8 into the mounting hole of the housing assembly. The floating stage cylinder 506 then presses down the gripper assembly, installing the rotor 8 into the housing assembly. Both the first servo module 501 and the second servo module 502 use servo linear motor modules to output precise linear motion. By setting the first servo module 501 and the second servo module 502 perpendicularly to each other, the gripper assembly can drive the rotor 8 to move linearly in both the horizontal and vertical directions, achieving efficient and accurate assembly.

[0052] The gripper assembly includes at least three grippers 508, and the working end face of each gripper 508 is provided with a concave arc surface 509. By providing three grippers 508, which are evenly distributed along the circumference, and the concave arc surface 509 corresponding to the shape of the outer circular surface of the rotating shaft on the rotor 8, the stability of the gripper assembly in gripping the rotor 8 is improved, thereby achieving stable gripping of the rotor 8.

[0053] The lifting and positioning mechanism 1, the clamping mechanism 2, and the workpiece carrier 3 are all supported by the mounting base 4. Specifically, the lifting cylinder 101 is fixed to the fixing plate 104, and the fixing plate 104 is installed at the bottom of the mounting base 4 through several connecting columns 103; the rotating clamping cylinder 201 is fixed to the mounting base 4; the carrier plate 303 is detachably installed on the top of the mounting base 4, and a proximity switch 14 is installed on the top of the mounting base 4 to detect whether the carrier plate 303 is in place; in addition, a mounting frame can be set below the mounting base 4 to support it.

[0054] A support frame 7 is fixed to the top of the mounting base 4, which supports the transfer mechanism 5. Several slide rails 503 are fixed to the top of the support frame 7, and several sliders 504 are installed on each slide rail 503. The sliders 504 are fixed to the bottom of the moving base 505. By setting the slide rails 503 and sliders 504, the movement stability of the moving base 505 can be improved.

[0055] The top of the mounting base 4 is fitted with a material box 6. The material box 6 is used to place the assembled product.

[0056] In this invention, the top of the mounting base 4 is equipped with two barcode readers 11. One barcode reader 11 is arranged on one side of the rotor placement base 301 to identify the model of the corresponding rotor 8, and the other barcode reader 11 is arranged on one side of the housing placement base 302 to identify the model of the corresponding housing 9, ensuring that the rotor 8 to be assembled corresponds to the housing component model and avoiding misassembly problems. The top of the mounting base 4 is also equipped with an image sensor 12, which is used to take pictures of the rotor 8 on the rotor placement base 301 to prevent the rotor 8 from being placed backwards. The top of the mounting base 4 is also equipped with three photoelectric sensors 13, which are respectively arranged with the material box 6, the rotor placement base 301 and the housing placement base 302 to detect whether there is material at the corresponding position.

[0057] The working process of this utility model is as follows:

[0058] Place the rotor 8 with assembly on the rotor placement seat 301, place the housing assembly to be assembled on the housing placement seat 302, and then place the workpiece carrier 3 on the corresponding position of the mounting seat 4.

[0059] The corresponding code reader 11 reads codes on the rotor 8 and the housing 9 respectively, and the image sensor 12 detects the orientation of the rotor 8;

[0060] After the inspection is completed, the lifting cylinder 101 extends and drives the positioning pin 102 to be inserted into the shaft hole of the housing 9, thereby positioning the housing assembly. Then, the rotary clamping cylinder 201 is activated, driving the pressure plate 202 to rotate first and then press down, thereby clamping the housing assembly.

[0061] Next, the first servo module 501 is activated, driving the gripper assembly to move directly above the corresponding rotor 8. The second servo module 502 is activated, driving the gripper assembly to descend. After descending to the correct position, the power chuck 507 is activated, driving the gripper 508 to perform a similar movement, thereby gripping the corresponding rotor 8. After stable gripping, the second servo module 502 is activated, driving the rotor 8 to rise through the gripper assembly. After rising to the correct position, the first servo module 501 drives the rotor 8 to move directly above the housing assembly through the gripper assembly.

[0062] Then, the second servo module 502 is activated, and the rotor 8 is driven down through the gripper assembly until the shaft located below the rotor 8 is lowered to the shaft hole inlet.

[0063] Finally, the lifting cylinder 101 retracts, the driving positioning column 102 extends out of the shaft hole of the housing 9, the floating table cylinder 506 is de-aired and floats, and the rotor 8 is driven to descend further through the gripper assembly, so that the rotating shaft located below the rotor 8 is inserted into the shaft hole of the housing 9, thereby pressing the rotor 8 into place.
