Description

Technical Field

[0001] The present invention relates to the technical field of assembly equipment, and particularly to a motor assembler for electric vehicles. Background Art

[0002] The motor, commonly known as the motor, is an important part of electromechanical equipment. A rotor and a stator are installed inside the motor. After the motor is powered on, the rotor coil rotates to cut the stator magnetic field and makes a circular motion. The motor is a device that converts electrical energy into mechanical energy and is converted into different motion modes through various transmission structures. In the overall assembly process of the motor, the assembly process of the motor stator plays a key role in the assembly accuracy of other accessories.

[0003] In the prior art, a patent document with the publication number of CN221305704U discloses a motor stator assembly device, including: a mounting base plate, a support rod and a top plate. An activity groove is opened at the top of the mounting base plate, and a mounting frame. The top of the mounting frame is fixedly connected with a placement table. Through the mutual cooperation among the mounting base plate, the support rod, the top plate, the activity groove, the mounting frame, the limiting mechanism, the displacement mechanism, the pressing mechanism, the rubber pad and the placement table, the present invention realizes a motor stator assembly device. The housing and the stator are placed in the placement groove at the top of the placement table. Under the elastic action of the return spring, the supporting frame is pushed to limit the position of the stator. When the placement table reaches the corresponding position, the air cylinder pushes the pressing block to press the stator into the housing. Due to the limitation of the supporting frame, the position of the stator can always be kept stable during the movement or pressing process of the stator, avoiding the deviation of the position of the stator and the housing caused by vibration, thereby ensuring the qualification rate of the product.

[0004] It is found during use that when the above device clamps the motor stator assembly through the connecting rod, the return spring and the supporting frame, manual adjustment by the staff is required, which increases the labor intensity of the staff and has poor convenience. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a motor assembler for electric vehicles that improves convenience.

[0006] A motor assembler for an electric vehicle according to the present invention includes a workbench, a concave groove, a controller, and guide grooves. A concave groove is provided at the top of the workbench, a controller is provided at the front end of the workbench, and two sets of guide grooves are symmetrically provided at the top of the workbench. The concave groove is between the two sets of guide grooves. It also includes a positioning component, a clamping component, and a pressing component. A positioning component is slidably provided in the concave groove, two sets of clamping components are symmetrically provided on the positioning component, and a pressing component is provided at the top of the workbench. The rear parts of the two sets of guide grooves are parallel, and the front parts of the two sets of guide grooves are in a "V" shape. When in use, the outer shell and the stator are placed on the positioning component for preliminary positioning. Then, the positioning component is started, so that the positioning component drives the outer shell and the stator to move directly below the pressing component. During the movement of the positioning component, the two sets of clamping components are started to clamp and fix the outer shell and the stator. When the outer shell and the stator move directly below the pressing component, the pressing component is operated to press-fit and assemble the stator and the outer shell. After the assembly is completed, the positioning component moves forward in the concave groove. During the forward movement, the two sets of clamping components release the clamping of the assembled outer shell and stator, realizing the automatic pressing and automatic release of the clamping of the outer shell by the clamping component.

[0007] Preferably, the positioning component includes a servo motor, a first lead screw, a first optical rod, a positioning seat, a positioning groove, a strip-shaped opening, and a moving seat. A first lead screw is rotatably provided inside the concave groove, a first optical rod is fixedly provided inside the concave groove, the moving seat is threadedly connected to the first lead screw, and the first optical rod is slidably connected to the moving seat. A servo motor is provided at the front end of the workbench, and the output end of the servo motor is connected to one end of the first lead screw. A positioning seat is provided at the top of the moving seat, a positioning groove is provided at the top of the positioning seat, two sets of strip-shaped openings are provided on the positioning seat, and the positioning groove is between the two sets of strip-shaped openings. The servo motor is electrically connected to the controller, and the clamping component is provided in the strip-shaped opening. The outer shell and the stator are placed inside the positioning groove for preliminary positioning. Then, the servo motor is started through the controller, so that the servo motor drives the first lead screw to rotate in the concave groove. Since the first lead screw is threadedly connected to the moving seat, and at the same time the moving seat is slidably connected to the first optical rod, the first lead screw drives the moving seat to move backward in the concave groove, further enabling the positioning seat to drive the outer shell and the stator to move backward through the positioning groove. During the movement, the two sets of clamping components approach each other, thereby clamping and fixing the outer shell. After the assembly is completed, the positioning seat moves forward, and the two sets of clamping components release the clamping of the outer shell, improving convenience.

[0008] Preferably, the clamping assembly includes guide rods, support arms, guide wheels, second lead screws, second optical rods, moving plates, first springs, first telescopic rods, support frames and hand wheels.

Second lead screws are screwed on the support arms. The inner ends of the second lead screws are rotatably arranged with moving plates. Second optical rods are fixedly arranged on the moving plates. The second optical rods are slidably connected to the support arms. Hand wheels are arranged at the outer ends of the second lead screws. Grooves are arranged at the inner ends of the moving plates. First telescopic rods are arranged in the grooves. A set of first springs are respectively sleeved outside each group of first telescopic rods. The inner ends of the first telescopic rods and the first springs are both connected to one end of the support frame. During use, the two guide wheels are respectively at the front parts of the two guide grooves. Place the outer shell and the stator in the positioning grooves. Then operate the positioning seat to move backward. During the movement, the two guide wheels move backward following the positioning seat. The two guide wheels move from the front parts of the guide grooves to the rear parts of the guide grooves. During the movement, the two guide wheels move closer in a mirror image manner. Thus, the support arms move closer in a mirror image manner under the guidance of the guide rods. Then, the two support frames clamp and fix the outer side wall of the outer shell in cooperation with the corresponding first springs and first telescopic rods. Then, automatic clamping is performed. After the press-fitting is completed, the positioning seat moves forward. The two guide wheels move from the rear parts of the guide grooves to the front parts of the guide grooves. Thus, the two support arms move away from each other in a mirror image manner, realizing the release of the clamping of the outer shell.

[0009] Preferably, the pressing-down assembly includes support columns, a top plate, an electric hydraulic cylinder, a lifting plate, a pressing-down block and an optical rod. Two support columns are arranged at the top end of the workbench. The top ends of the two support columns are both connected to the bottom end of the top plate. An electric hydraulic cylinder is arranged at the top end of the top plate. The bottom mobile end of the electric hydraulic cylinder extends below the top plate and is connected to the top end of the lifting plate. A pressing-down block is arranged at the bottom end of the lifting plate. An optical rod is arranged at the top end of the lifting plate. The optical rod is slidably connected to the top plate. The electric hydraulic cylinder is electrically connected to the controller. During use, when the outer shell and the stator move to directly below the pressing-down block through the positioning seat, operate the electric hydraulic cylinder to extend. Thus, the lifting plate drives the pressing-down block to move downward in cooperation with the optical rod. Further, the pressing-down block presses and installs the stator on the outer shell, thereby realizing the assembly of the outer shell and the stator and improving the assembly efficiency.

[0010] Preferably, it also includes a U-shaped frame, a protective plate, a No. 3 light bar, a No. 3 spring, a fixed bracket, a photoelectric signal transmitter, a photoelectric signal receiver and a baffle, two groups of U-shaped frames are arranged on the top of the workbench, a group of No. 3 light bars are fixedly arranged inside each group of U-shaped frames, the protective plate is slidably connected to the two groups of No. 3 light bars, each group of No. 3 light bars is respectively equipped with a group of No. 3 springs, and the No. 3 springs are all at the rear end of the protective plate, a fixed bracket is arranged on the top of the workbench, a photoelectric signal transmitter is installed on the fixed bracket, a photoelectric signal receiver is arranged on the top of the workbench, and the photoelectric signal receiver is directly below the photoelectric signal transmitter, a baffle is arranged on the top of the positioning seat, and the photoelectric signal transmitter, the wheel and the controller are electrically connected; under normal conditions, the protective plate is elastically supported by the two groups of No. 3 springs. With the cooperation of the two sets of U-shaped frames, it is on the internal front side of the two sets of U-shaped frames and directly below the lower pressure block to prevent misoperation. When in use, when the positioning seat drives the shell and the stator to move backward, the baffle and the positioning seat move synchronously, and the baffle contacts the front end of the protective plate, so that the baffle pushes the protective plate to move backward, and the protective plate releases the downward limit on the lower pressure block. When the protective plate moves between the photoelectric signal transmitter and the photoelectric signal receiver, the protective plate isolates the signal between the photoelectric signal transmitter and the photoelectric signal receiver, and the controller operates the electric hydraulic cylinder to extend. After the pressing is completed, the protective plate moves forward under the action of the elastic force of the No. 3 spring, and the protective plate releases the signal isolation between the photoelectric signal transmitter and the photoelectric signal receiver, thereby shortening the electric hydraulic cylinder and at the same time the protective plate limits the downward movement of the lower pressure block again to improve safety.

[0011] Preferably, it also includes a support frame and wheels, a group of support frames are respectively arranged at the four corners of the bottom end of the positioning seat, a group of wheels are rotatably arranged on each group of support frames, and the four groups of wheels are in rolling contact with the top of the workbench; when the positioning seat moves back and forth inside the concave groove, the multiple groups of wheels rotate adaptively, and the four groups of wheels and the four groups of support frames cooperate with each other to stably support the positioning seat, thereby improving stability.

[0015] Preferably, it further includes a locking nut, and a locking nut is arranged on each second lead screw; after the staff rotates the second lead screw through the handwheel, the locking nut is rotated to make the locking nut close to the support arm, so as to complete the locking of the second lead screw and prevent the second lead screw from rotating self.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: during use, the outer shell and the stator are placed on the positioning component for preliminary positioning, and then the positioning component is started, so that the positioning component drives the outer shell and the stator to move directly below the pressing component. During the movement of the positioning component, two sets of clamping components are started to clamp and fix the outer shell and the stator. When the outer shell and the stator move directly below the pressing component, the pressing component is operated to press-fit and assemble the stator and the outer shell.

The two sets of guide wheels 303 move from the front part of the guiding groove 104 to the rear part of the guiding groove 104, and the two sets of guide wheels 303 move closer in a mirror image manner, so that the support arms 302 move closer in a mirror image manner under the guidance of the guide rod 301. Then, the two sets of holding frames 309 clamp and fix the outer side wall of the housing in cooperation with the corresponding first springs 307 and first telescopic rods 308, and then automatically clamp. When the housing and the stator move to directly below the pressing block 405 through the positioning seat 204, the baffle 509 moves synchronously with the positioning seat 204, and the baffle 509 contacts the front end of the protection plate 503, so that the baffle 509 pushes the protection plate 503 to move backward, and the protection plate 503 releases the downward limit on the pressing block 405. When the protection plate 503 moves between the photoelectric signal transmitter 507 and the photoelectric signal receiver 508, and the protection plate 503 blocks the signal between the photoelectric signal transmitter 507 and the photoelectric signal receiver 508, the controller 103 operates the electric hydraulic cylinder 403 to extend, so that the lifting plate 404 drives the pressing block 405 to move downward in cooperation with the optical bar 406. Further, the pressing block 405 presses and installs the stator on the housing, thereby realizing the assembly of the housing and the stator. After the pressing and installation is completed, the positioning seat 204 moves forward, and the two sets of guide wheels 303 move from the rear part of the guiding groove 104 to the front part of the guiding groove 104, so that the two sets of support arms 302 move away in a mirror image manner, realizing the release of the clamping on the housing assembly.
