Figure 1 and Figure 2 As shown, it includes: a base 1; a limiting frame assembly 2, which is connected to the base 1; a riveting device 3, which is connected to the side of the limiting frame assembly 2 away from the base 1, for riveting and pressurizing the retaining ring; a retaining ring limiting assembly 4, which is connected to the limiting frame assembly 2, for pressing and fixing the retaining ring; and a motor limiting device 5, which is connected to the base 1. The motor limiting device 5 includes: a first positioning device 6, which is connected to the base 1, for limiting the connection of motors of different specifications; and a second positioning device 7, which is connected to the first positioning device 6, for positioning the retaining ring limiting assembly 4 during connection.

[0023] In one embodiment of the present invention:

[0024] like Figure 1 and Figure 2 As shown, the limiting frame assembly 2 includes: at least two first supports 201, the first supports 201 being connected to the base 1; a first limiting slide groove 202, the first limiting slide groove 202 being disposed inside the first supports 201; a first top frame 203, the first top frame 203 being connected to the ends of the two first supports 201 away from the base 1; and a positioning frame 204, the positioning frame 204 being slidably connected to the first limiting slide groove 202;

[0025] When performing motor shaft retainer riveting, the motor to be processed is placed longitudinally in the middle of the base 1 with the shaft facing upward. The retainer to be riveted is manually placed in the set position on the motor shaft, and the motor is manually supported. Then the motor limiting device 5 operates to limit and clamp the motor, while driving the retainer limiting component 4 to operate in conjunction, so as to achieve pressing and positioning of the retainer.

[0026] In one embodiment of the present invention:

[0027] like Figure 1 and Figure 2 As shown, the riveting device 3 includes: at least two second supports 301, the second supports 301 being connected to a first top frame 203; a second top frame 302, the second top frame 302 being fixedly connected to the end of the second supports 301 away from the first top frame 203; a first driving member 303, the first driving member 303 being connected to the second top frame 302; the first driving member 303 is an electric slide; a second driving member 304, the second driving member 304 being connected to the first driving member 303; the second driving member 304 is an electric telescopic frame; and a riveting member 305, the riveting member 305 being connected to the second driving member 304; the riveting member 305 is a riveting machine.

[0028] Driven by the first driving member 303 and the second driving member 304, the riveting member 305 can be adjusted laterally and longitudinally, so as to perform directional riveting processing according to the actual required riveting position of the retaining ring.

[0029] In this application, the first driving component 303 and the second driving component 304 are not limited to electric slides and electric telescopic frames. They can also be driven by multi-axis cylinder adjusting arms, etc., as long as they can achieve the lateral and longitudinal adjustment of the riveting component 305. No specific limitation is made here.

[0030] In one embodiment of the present invention:

[0031] like Figure 1 and Figure 3 As shown, the first positioning device 6 includes: at least two third driving members 601, the third driving members 601 being connected to the base 1; the third driving members 601 are selected as electric telescopic frames; a platform 602, the platform 602 being connected to the end of the third driving members 601 away from the base 1, and connected to the positioning frame 204; a second elastic member 603, the second elastic member 603 being connected to the bottom side of the platform 602; the second elastic member 603 is selected as a spring ring frame; and a transmission frame 604, the transmission frame 601... 4. Connected to the second elastic element 603; an arc-shaped frame 605, the arc-shaped frame 605 being connected to the end of the transmission frame 604 away from the second elastic element 603, and its bottom side being slidably connected to the base 1; at least two limiting frames 606, the limiting frames 606 being fixedly connected to the base 1; a limiting connecting frame 607, one end of the limiting connecting frame 607 being fixedly connected to the arc-shaped frame 605, and the other end being slidably connected to the inside of the limiting frame 606; a buffer pad 608, the buffer pad 608 being disposed inside the arc-shaped frame 605;

[0032] According to the actual size and specifications of the motor, motors of different specifications can be clamped and limited by the motor limiting device 5. When limiting, the third driving members 601 on both sides move vertically downward, driving the two side platforms 602 to move downward synchronously. When the two side platforms 602 move downward, they can drive the positioning frame 204 to slide within the first limiting groove 202. With the cooperation of the second elastic member 603 and the transmission frame 604, the two side arc frames 605 can move in opposite directions, thereby realizing the opposite clamping of the motor in the middle. At the same time, the limiting connecting frame 607 connected to the arc frame 605 can slide within the limiting frame 606, further improving the movement stability of the arc frame 605.

[0033] In this application, the third driving component 601 is not limited to an electric telescopic frame. It can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the longitudinal movement adjustment of the platform 602. No specific limitation is made here.

[0034] In one embodiment of the present invention:

[0035] like Figure 1 and Figure 4 As shown, the retaining ring limiting assembly 4 includes: a transmission frame 401, which is connected to the top side of the two side platforms 602; a first elastic member 402, which is fixedly connected to the transmission frame 401; the first elastic member 402 is an elastic telescopic frame; and a positioning plate frame 403, which is connected to the end of the first elastic member 402 away from the transmission frame 401.

[0036] The motor retaining ring should be placed directly below the positioning plate frame 403. The positioning plate frame 403 is V-shaped. When the two side frames 602 move downwards longitudinally, in conjunction with the transmission frame 401, the first elastic element 402 and the positioning plate frame 403 can move downwards synchronously, so that the positioning plate frame 403 elastically abuts against the top side of the positioning retaining ring. The elastically set first elastic element 402 can increase the fixing range of the retaining ring limiting component 4 when the motor limiting device 5 limits the motor. When fixing, the retaining ring limiting component 4 first elastically abuts against the retaining ring, and then the bottom motor limiting device 5 clamps and fixes the motor. When the motor limiting device 5 continues to clamp in opposite directions, the retaining ring limiting component 4 can maintain the elastic abutment state with the retaining ring and continue to contract.

[0037] In one embodiment of the present invention:

[0038] like Figure 1 As shown, the retaining ring limiting assembly 4 further includes: a plurality of limiting slots 404, the limiting slots 404 being disposed inside both sides of the first elastic member 402;

[0039] After the positioning plate frame 403 elastically presses the retaining ring, adjust the second positioning devices 7 on both sides and insert them into the corresponding height limit slots 404 to complete the secondary limiting of the retaining ring limit assembly 4.

[0040] In one embodiment of the present invention:

[0041] like Figure 1 As shown, the second positioning device 7 includes: a second limiting slide groove 701, which is disposed inside the platform 602; a connecting frame 702, which is slidably connected to the second limiting slide groove 701; and a limiting locking frame 703, which is slidably connected to the top side of the platform 602 and passes through the platform 602 and is connected to the connecting frame 702.

[0042] After the retaining ring limiting component 4 is pressed, the connecting brackets 702 on both sides are manually moved along the second limiting slide groove 701 to drive the limiting snap-fit ​​bracket 703 to move in opposite directions and insert into the limiting slot 404 at the corresponding position to complete the snap-fit ​​limiting of the retaining ring limiting component 4. At the same time, the fixing stability of the motor by the first positioning device 6 is further improved.

[0043] The working principle of this invention is as follows: When performing motor shaft retaining ring riveting, the motor to be processed is placed longitudinally in the middle of the base 1 with the shaft facing upwards. The retaining ring to be riveted is manually placed in the set position on the motor shaft, and the motor is manually supported. Then, the motor limiting device 5 operates, limiting and clamping the motor while simultaneously driving the retaining ring limiting component 4 to operate in conjunction, thereby achieving pressing and positioning of the retaining ring. Under the drive of the first driving component 303 and the second driving component 304, the riveting component 305 can be driven to perform lateral and longitudinal adjustments, thereby performing directional riveting according to the actual required riveting position of the retaining ring. The first driving component 303 and the second driving component 304 are not limited to electric slides and electric telescopic frames; they can also be driven by multi-axis cylinder adjusting arms, etc. The lateral and longitudinal adjustment of the riveting part 305 can be achieved without specific limitations. Depending on the actual size and specifications of the motor, the motor limiting device 5 can clamp and limit motors of different specifications. When limiting, the third driving parts 601 on both sides move longitudinally downward, driving the two side platforms 602 to move downward synchronously. When the two side platforms 602 move downward, they can drive the positioning frame 204 to slide within the first limiting groove 202. With the cooperation of the second elastic part 603 and the transmission frame 604, the two side arc frames 605 can move in opposite directions, thereby achieving opposite clamping of the central motor. At the same time, the limiting connecting frame 607 connected to the arc frame 605 can slide within the limiting frame 606, further improving the movement stability of the arc frame 605.

[0044] The motor retaining ring should be placed directly below the positioning plate frame 403. The positioning plate frame 403 is V-shaped. When the two side frames 602 move vertically downward, in conjunction with the transmission frame 401, it can drive the first elastic element 402 and the positioning plate frame 403 to move downward synchronously, so that the positioning plate frame 403 elastically abuts against the top side of the positioning retaining ring. The elastically set first elastic element 402 can increase the fixing range of the retaining ring limiting component 4 when the motor limiting device 5 limits the motor. When fixing, the retaining ring limiting component 4 first elastically abuts against the retaining ring, and then the bottom motor limiting device 5 clamps and fixes the motor. When the motor limiting device 5 continuously... When clamped in opposite directions, the retaining ring limiting component 4 can maintain elastic contact with the retaining ring and continuously retract. After the positioning plate frame 403 has finished elastically pressing the retaining ring, the second positioning devices 7 on both sides are adjusted and inserted into the limiting slots 404 at the corresponding height to complete the secondary limiting of the retaining ring limiting component 4. After the retaining ring limiting component 4 has finished pressing, the connecting frames 702 on both sides are manually moved in opposite directions along the second limiting slide groove 701, which drives the limiting snap-fit ​​frame 703 to move in opposite directions and insert into the limiting slots 404 at the corresponding positions to complete the snap-fit ​​limiting of the retaining ring limiting component 4. At the same time, the fixing stability of the motor by the first positioning device 6 is further improved.

[0045] In summary, the first positioning device 6 of this device can limit and fix motors of different specifications, and at the same time drive the retaining ring limiting component 4 to operate synchronously to achieve linkage pressing and limiting of the retaining ring. In conjunction with the second positioning device 7, it completes the secondary limiting of the retaining ring limiting component 4, and further improves the clamping stability of the motor.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
