Description

Technical Field

[0001] The invention belongs to the field of mechanical feeding, and in particular relates to a feeding mechanism and a feeding method for a motor coil rolling riveting process. Background Art

[0002] At present, the assembly of motor coils generally uses fixed top cores for auxiliary assembly to save manpower and material resources. However, when screwing in bolts during assembly, the motor housing equipped with the fixed top core needs to be placed on the bolt tightening station. After tightening, the fixed top core needs to be taken out of the motor housing. When transporting and taking out the fixed top core, a good loading mechanism is needed to complete these actions, which is not only convenient, but also can shorten the turnover cycle and improve work efficiency. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the problems of the prior art and provide a motor coil rolling riveting process feeding mechanism and feeding method which is convenient for feeding and saves working time.

[0004] In order to solve the above technical problems, a technical solution provided by the present invention is: A feeding mechanism for a motor coil rolling riveting process comprises a track frame with a feeding module, the feeding module comprises a driving slider and a telescopic motor, the driving slider is arranged on the track frame, the fixed end of the telescopic motor is connected to the driving slider, the telescopic end is connected to a clamping motor, the clamping motor is provided with an outer clamp capable of clamping a motor housing, and the outer clamp is provided with an inner clamp capable of clamping a fixed top core.

[0005] Furthermore, the outer clamp includes at least three outer clamp arms, each of which includes a connecting arm, an extension arm and a clamping arm. One end of the connecting arm is connected to the clamp motor, and the other end is connected to the upper end surface of the inner end of the horizontal extension arm. The clamping arm is connected to the lower end surface of the outer end of the extension arm.

[0006] Furthermore, the inner clamp includes at least three L-shaped inner clamp arms, which are arranged one by one corresponding to the outer clamp arms, and each of the lower end faces of the inner end of the laterally arranged outer extension arm is connected to an inner clamp arm, and the open end of the inner clamp arm faces the direction of the clamping arm.

[0007] Furthermore, a clamping gasket is provided on the inner side of the clamping arm.

[0008] Furthermore, the connecting arm, the extension arm and the clamping arm are an integrated structure.

[0009] A feeding method for a feeding mechanism of a motor coil rolling riveting process comprises the following steps: S1: using the driving slider to drive the feeding module to run to the upper end of the motor casing with a fixed top core to be clamped, then extending the telescopic motor to lower the clamping claw motor to the motor casing, and using the clamping claw motor to control the outer clamping claw to clamp the motor casing; S2: After clamping, the telescopic motor is retracted, the motor housing is lifted, and the driving slider is used to drive the motor housing to move on the track frame until it moves to the rolling and riveting working position of the motor coil, and the telescopic motor is extended to place the motor housing on the rolling and riveting working table; S3: When the motor housing is placed on the rolling and riveting workbench, the fixed core in the motor housing is pushed out of the motor housing by using the fixed core platform on the workbench. At this time, the clamping motor controls the outer clamping jaw to loosen the motor housing, and further extends the telescopic motor to move downward, so that the inner clamping jaw moves to the inside of the fixed core and is flush with the annular groove inside the fixed core. S4: After being leveled, the clamping jaw motor controls the inner clamping jaw to further pull outward, so that the L-shaped inner clamping jaw arm enters the annular groove and is fixed; S5: retract the telescopic motor, pull up the fixed top core, and after the fixed top core is completely out of the working area of ​​the rolling and riveting workbench, use the driving slider to transport the fixed top core along the track frame to the storage area.

[0010] The fixed top core in the motor housing is fixed in the motor housing by utilizing its own friction force and the friction force between the gasket and the motor coil, and will not slide out of the motor housing by relying on its own gravity without the action of external force.

[0011] The beneficial effects of the present invention are: The feeding mechanism in the present invention realizes movement in the horizontal space by driving the movement of the motor on the track frame, realizes movement in the vertical direction by the extension and retraction of the telescopic motor, realizes the tightening and loosening of the motor casing by the clamping motor, and after the fixation is completed, the fixed top core is taken out from the motor casing by the inner clamping jaws on the clamping jaw motor. No manual participation is required in the whole process, and mechanized operation is used, which is convenient for assembly line work, saves working time, and improves work efficiency.

[0018] The names of the messages or information exchanged between multiple devices in the embodiments of the present invention are only used for illustrative purposes, and are not used to limit the scope of these messages or information.

[0019] Example: Figure 1-6 As shown, A feeding mechanism for a motor coil rolling riveting process comprises a track frame 1 with a feeding module, wherein the feeding module comprises a driving slider 2 and a telescopic motor 3, wherein the driving slider 2 is arranged on the track frame 1 and can move along a track on the track frame 1.

[0020] The fixed end of the telescopic motor 3 is connected to the driving slider 2 , and the telescopic end is connected to the clamping claw motor 4 . The telescopic motor 3 can be used to realize the up and down movement of the clamping claw motor 4 .

[0021] The clamping motor 4 is provided with an outer clamping jaw 5 capable of clamping the motor housing, so as to facilitate moving the motor housing to a predetermined position.

[0022] The outer clamp 5 is provided with an inner clamp 6 capable of clamping the fixed top core, so that the fixed top core can be taken out from the motor casing and transferred to the storage area. The fixed top core in the motor casing is fixed in the motor casing by its own friction force and the friction force between the gasket and the motor coil. In the absence of external force, it will not slide out of the motor casing by its own gravity.

[0023] The outer clamping jaw 5 includes three outer clamping jaws, which are arranged in a T-shape. Each outer clamping jaw includes a connecting arm 5-1, an extension arm 5-2 and a clamping arm 5-3. One end of the connecting arm 5-1 is connected to the clamping jaw motor 4, and the other end is connected to the upper end surface of the inner end of the horizontal extension arm 5-2. The clamping arm 5-3 is connected to the lower end surface of the outer end of the extension arm 5-2. The connecting arm 5-1, the extension arm 5-2 and the clamping arm 5-3 are an integrated structure. A clamping gasket 7 is arranged on the inner side of the clamping arm 5-3. The clamping gasket 7 can increase the friction between the clamping arm 5-3 and the motor housing, making the clamping more secure and easier.

[0024] The inner clamping jaw 6 includes three L-shaped inner claw arms, which are arranged one by one with the outer claw arms. An inner claw arm is connected to the lower end surface of the inner end of each laterally arranged outer extension arm 5-2, and the open end of the inner claw arm faces the direction of the clamping arm 5-3, which is convenient for inserting the L-shaped inner claw arm into the annular groove so that the fixed top core can be removed from the motor housing.

[0025] When in use, the driving slider 2 is used to drive the feeding module to run to the upper end of the motor casing with a fixed top core that needs to be clamped, and then the telescopic motor 3 is extended to lower the clamping jaw motor 4 to the motor casing, and the clamping jaw motor 4 is used to control the outer clamping jaw 5 to clamp the motor casing.

[0026] After clamping, retract the telescopic motor 3, lift the motor housing, and use the driving slider 2 to drive the motor housing to move on the track frame 1, move it to the motor coil rolling and riveting working position, extend the telescopic motor 3 and lower the motor housing onto the rolling and riveting workbench.

[0027] When the motor casing is lowered onto the riveting workbench, the fixed core inside the motor casing is pushed out of the motor casing by using the fixed core platform on the workbench. At this time, the clamping motor 4 controls the outer clamping jaw 5 to loosen the motor casing, and further extends the telescopic motor 3 to move downward, so that the inner clamping jaw 6 moves to the inside of the fixed top core and is flush with the annular groove inside the fixed top core.

[0028] After being leveled, the clamping jaw motor 4 controls the inner clamping jaw 6 to be further pulled outward, so that the L-shaped inner clamping jaw arm enters the annular groove and is fixed.

[0029] Finally, the telescopic motor 3 is retracted to pull up the fixed top core. After the fixed top core is completely out of the working area of ​​the rolling and riveting workbench, the driving slider 2 is used to transport the fixed top core along the track frame 1 to the storage area.

[0030] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
