[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0025] The embodiment of the present application provides a starter drive cover pressing tool, which can solve the defects of using installation stopper positioning, requiring many kinds of positioning bases for eccentric starters, making replacement complicated and affecting production rhythm.

[0026] See also Figures 1 to 3 As shown, an embodiment of the present application provides a starter drive cover press-fitting tool. The present application installs the starter drive cover press-fitting tool on a press. The starter drive cover press-fitting tool includes: a punching and riveting part 1 and a base, a positioning seat 3 and a concentric seat 4. One end of the riveting part 1 is used to connect to the power drive of the press-fitting equipment, and the other end is used to rivet the end face of the starter drive cover. In the present application, the press-fitting device includes but is not limited to a press, and the riveting part 1 can receive and transmit the power generated by the press; a base is provided for connecting to the working platform of the press-fitting equipment, and the base can ensure the stability and accuracy of the entire tooling during the working process; the connection of the positioning seat 3 is achieved by providing a mounting groove 210 on the base, and the positioning seat 3 is inserted in the mounting groove 210 and coaxially connected to the base, and the positioning seat 3 provides a precise positioning reference; the connection of the concentric seat 4 is achieved by providing a positioning groove 300 on the positioning seat 3, and the bottom wall of the positioning groove 300 is coaxially provided with a slot 301, the positioning seat 3 is coaxially connected to the concentric seat 4 in the positioning groove 300, and one end of the concentric seat 4 is inserted in the slot 301, and the other end is used to be coaxially connected to the inner stop of the starter drive cover, and then a processing area for placing the starter drive cover is formed on the outer wall of the concentric seat 4 and the inner wall of the positioning groove 300.

[0027] In the present application, the concentric seat 4 is provided with at least three shaft sections, among which the diameter of the middle shaft section is the largest, and the diameter of the shaft section inserted into the slot 301 is larger than the diameter of the shaft section 80 coaxially connected to the inner stop of the starter drive cover. When in use, the starter drive cover is sleeved on the concentric seat 4, and the concentric seat 4 can directly position the starter drive cover. At that time, the punching and riveting part 1 punches and rivets downward along the axis of the concentric seat 4 to place the starter drive cover in the processing area of ​​the starter drive cover, and effectively completes the punching and riveting of the starter drive cover.

[0028] During the use of the starter drive cover press fitting tool, in order to adapt to starters with different eccentricities and angles, the positioning seat 3 can be replaced to ensure the accuracy and stability of positioning. The inner stopper of the starter drive cover is concentric with the bearing mounting hole, so the concentric seat 4 inserted on the positioning seat 3 is coaxially connected and positioned with the inner stopper of the starter drive cover, that is, by positioning with the inner stopper, accurate positioning can be achieved regardless of how the eccentricity and angle of the starter change, reducing production interruptions caused by tool replacement and improving the versatility of the starter drive cover press fitting tool.

[0029] In the present application, the starter drive cover pressing tooling also includes a correction sleeve 5 and a support block 6. In addition, a correction block 7 is provided concentrically along the axis of the end of the punching and riveting part 1 close to the starter drive cover. One end of the correction sleeve 5 is sleeved with the correction block 7, and the other end is sleeved on the support block 6. A positioning hole is also provided on the support block 6 coaxial with the correction block 7, and the end of the concentric seat 4 away from the positioning seat 3 is inserted into the positioning hole. When in use, the correction block 7, the correction sleeve 5, the support block 6 and the concentric seat 4 are all on the same axis, so that the punching and riveting part 1 can be coaxially aligned with the concentric seat 4. The function is to calibrate the punching and riveting part 1 and the concentric seat 4 after starting a shift or replacing the tooling, so as to ensure the processing accuracy of the starter drive cover. After the calibration is completed, the correction sleeve 5 can be removed.

[0030] During specific use, when the punching and riveting part 1 moves downward to drive the correction block 7 to move close to the starter drive cover, the end face of the correction block 7 abuts against the top face of the support block 6, and then the cooperation between the correction block 7 and the support block can also limit the punching depth of the punching and riveting part 1 to ensure that the drive cover is not damaged by excessive pressure.

[0031] In the present application, the punching and riveting part 1 includes a mounting base 10 and a punching and riveting head 11, wherein the mounting base 10 is used to connect with the power drive of the press-fitting equipment, and the mounting base 10 is used as the main structure of the punching and riveting part 1 to ensure the stability and accuracy of the punching and riveting operation. A plurality of punching and riveting heads 11 are evenly distributed around one end of the mounting base 10 close to the starter drive cover, and the base is rotatably connected to the working platform of the press-fitting equipment.

[0032] When in use, the power drive of the press-fitting equipment drives the mounting base 10 to move downward, and multiple rivet heads 11 rivet the end surface of the starter drive cover. Then, according to the number of rivet points required, the base is rotated to change the position of the starter drive cover, and the starter drive cover is further repeatedly rivet.

[0033] In the present application, the base provided includes a connecting seat 20 and a rotating seat 21, the connecting seat 20 is fixedly connected to the working platform of the press-fitting equipment, the rotating seat 21 is rotatably connected to the connecting seat 20, the mounting groove 210 is provided on the rotating seat 21, and a rotating handle 211 is also provided on the rotating seat 21. The connection method between the connecting seat 20 and the rotating seat 21 includes but is not limited to the use of a coaxially arranged connecting hole on the connecting seat 20, a connecting shaft 80 is rotatably connected in the connecting hole, the connecting shaft 80 extends from the top of the connecting hole, and is rotatably connected to the rotating seat 21. The base is stable and reliable in use during the press-fitting process, and the rotating seat 21 can rotate within a certain range, providing more flexibility and convenience, and the position and angle of the mounting groove 210 and the components mounted thereon can be adjusted as needed to meet the press-fitting requirements of different workpieces. The setting of the rotating handle 211 allows the operator to easily drive the rotation of the rotating seat 21 by rotating the handle, which not only simplifies the operation process, but also improves work efficiency.

[0034] In the present application, a limit pin 22 is set on the rotating seat 21, and an arc groove 200 adapted to the limit pin 22 is provided on the connecting seat 20. The angle between the centers of the two ends of the arc groove 200 is marked as A, and A is set to 30 degrees, thereby ensuring that the rotation angle range of the rotating seat 21 is 30 degrees.

[0035] In the present application, six rivet heads 11 are provided, and the six rivet heads 11 are evenly distributed along the circumference of the mounting base 10. The interval between two adjacent rivet heads 11 is 60 degrees. After rotating the starter drive cover by 30 degrees, six more points can be riveted, achieving a total of 12 points of rivet.

[0036] In the present application, in order to ensure reliable connection between the rotating seat 21 and the connecting seat 20, a countersunk groove 81 is further provided on the bottom wall of the mounting groove 210, and a gasket 82 is provided on the bottom wall of the countersunk groove 81 located at the top of the connecting shaft 80, and a fastening screw 83 is connected between the gasket 82 and the connecting shaft 80. The fastening screw 83 cooperates with the connecting shaft 80 so that the gasket 82 is connected in the countersunk groove 81, and the gasket 82 restricts the shaking and displacement of the connecting shaft 80.

[0037] In the present application, the punching and riveting part 1 also includes an elastic pad 12 and a pre-pressed part 13. The mounting base 10 is used as the main structure of the punching and riveting part 1. A connecting groove is provided at one end of the mounting base 10. The notch of the connecting groove faces the starter drive cover. The connecting groove provides space for the installation and positioning of the elastic pad 12 and the pre-pressed part 13. The elastic pad 12 is connected to the bottom wall of the connecting groove. One end of the pre-pressed part 13 is located in the connecting groove and connected to the elastic pad 12. The other end of the pre-pressed part 13 extends from the notch of the connecting groove and is used to press against the end surface of the starter drive cover.

[0038] When in use, before the rivet head 11 rivets the starter drive cover downward, the pre-pressing piece 13 first contacts the starter drive cover, thereby squeezing the elastic pad 12 to generate an elastic restoring force. When the pressure of the press disappears, the elastic pad rebounds and pushes the pre-pressing piece 13 forward to withdraw the rivet head 11 from the workpiece. The displacement generated by the press simultaneously realizes the two actions of pre-pressing and riveting. The provision of the pre-pressing piece 13 helps to accurately position and pre-press the starter drive cover before riveting, thereby improving the accuracy and stability of the riveting operation. At the same time, the automatic withdrawal function also avoids the risk of the rivet head 11 being retained in the starter drive cover after the operation, thereby improving the safety of the operation.

[0039] In the present application, during the press-fitting process, the starter drive cover may be subjected to various forces and torques from the press-fitting equipment. If there is no constraint, the starter drive cover may undergo angular movement, resulting in inaccurate press-fitting or uneven distribution of punch points. Therefore, a locating pin 23 is also provided on the rotating seat 21, and the locating pin 23 is used to connect with the mounting hole on the starter drive cover to ensure the stability and position accuracy of the starter drive cover during the press-fitting process. Through the insertion and fixing of the locating pin, the starter drive cover is firmly locked in a predetermined position, thereby avoiding angular movement during the press-fitting process.
