This is to avoid the following description from becoming unnecessarily lengthy and to facilitate understanding by those skilled in the art. In addition, the drawings and the following description are provided to enable those skilled in the art to fully understand the present application and are not intended to limit the subject matter recited in the claims.

[0024] Please refer to Figures 1-4 As shown in the drawings, the utility model discloses a kind of automatic positioning devices for retaining ring processing, including rack 1, rack 1 top is provided with electric slide rail 2, several electric slide blocks 3 are slidably connected in electric slide rail 2 top, several electric slide blocks 3 are all provided with rotary drive assembly 4, rotary drive assembly 4 top is all provided with inner ring clamping mechanism 5, rack 1 top one side is provided with punching assembly 6, punching assembly 6 below is provided with locking assembly 7:

[0025] The electric sliding rail 2 drives the electric sliding block 3 to move on the rack 1, and plays a role of conveying the to-be-processed check ring 100. Through the driving of the electric sliding rail 2, a plurality of electric sliding blocks 3 move in turn, so that each to-be-processed check ring 100 can be moved from an initial position to a punching position below the punching assembly 6. In addition, the rotary driving assembly 4 is responsible for driving the check ring to rotate, and the inner ring clamping mechanism 5 can fix the to-be-processed check ring 100 above the rotary driving assembly 4, so that the to-be-processed check ring 100 can be rotated to the position needing to be punched by the rotary driving assembly 4 in turn, and multi-point punching can be realized. After the to-be-processed check ring 100 is rotated to each punching position, the punching assembly 6 locks the rotary driving assembly 4 by using the locking assembly 7, and punching operation is performed on the holes on the upper surface of the to-be-processed check ring 100. The locking assembly 7 fixes the overall position of the rotary driving assembly 4 after the rotary driving assembly 4 is adjusted to a position, and then prevents the to-be-processed check ring 100 from being deviated due to vibration or other external force in the punching process, so as to improve the stability and precision of processing. After the punching assembly 6 completes the punching operation, the locking assembly 7 is unlocked, the rotary driving assembly 4 continues to be adjusted to the next punching position, the above steps are repeated, until the to-be-processed check ring 100 is processed, and then the electric sliding block 3 is moved again to convey the to-be-processed check ring 100 to the next process for processing.

[0026] In one embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the rotary driving assembly 4 includes a driving motor 41, the driving motor 41 is arranged on the electric sliding block 3, and the output end of the driving motor 41 is fixedly connected with a rotary table 42. The rotary table 42 is provided above the inner ring clamping mechanism 5. The driving motor 41 can realize accurate angle adjustment of the rotary table 42, so as to rotate the to-be-processed check ring 100 to the position needing to be punched. The rotary table 42 provides a base for the inner ring clamping mechanism 5, so that the to-be-processed check ring 100 clamped can be adjusted in angle, thereby accurately aligning the position needing to be punched with the punching assembly 6. The inner ring clamping mechanism 5 is fixed on the rotary table 42, and is used for stably clamping the inner ring of the to-be-processed check ring 100. With the rotation of the rotary table 42, the inner ring clamping mechanism 5 and the to-be-processed check ring 100 rotate together, so that the position of the to-be-processed check ring 100 is always controlled during processing, and manual repeated adjustment of the position of the to-be-processed check ring 100 is not needed. The punching operation is completed point by point, and the phenomenon that the position of the check ring is deviated due to vibration or external force during the rotation and punching of the check ring, thereby causing processing error and affecting punching precision, can be avoided.

[0027] In one embodiment, as shown in Figure 1 , Figure 2 and Figure 3As shown, the upper part of the rotating stage 42 is provided with several locking grooves 421 along the circumferential direction. The locking grooves 421 are several grooves in the circumferential direction on the upper part of the rotating stage 42, and their function is to provide a precise docking position for the locking block 73 of the locking assembly 7. The locking grooves 421 can fix the rotating stage 42 at a specific angle, thereby ensuring that the surface of the retaining ring 100 to be processed is in the correct processing position.

[0028] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the inner ring clamping mechanism 5 includes a mounting plate 51, which is positioned above the rotating platform 42 on the opposite side. A first electric push rod 52 is mounted on the mounting plate 51. An inner clamping plate 53 is fixedly connected to the telescopic end of the first electric push rod 52. The inner clamping plate 53 is fixed to the telescopic end of the first electric push rod 52 and its function is to directly contact and clamp the inner ring of the retaining ring 100 to be processed. The position of the inner clamping plate 53 changes with the telescopic movement of the first electric push rod 52, thereby realizing the clamping or releasing operation. The inner clamping plate 53 can firmly clamp the inner ring of the retaining ring 100 to be processed, avoiding vibration or damage to the rotating platform 42 during processing. The movement of the retaining ring causes it to loosen, thus improving the processing accuracy. By adjusting the extension range of the first electric push rod 52, the inner ring clamping mechanism 5 can adapt to the processing requirements of various specifications of retaining rings 100 to be processed, and has high flexibility. The stable clamping of the inner ring clamping mechanism 5 ensures the precise positioning of the retaining ring 100 to be processed on the rotating platform 42. The drive motor 41 can rotate the platform 42 in real time, eliminating the need for manual repeated adjustment of the retaining ring position and completing the punching operation point by point. This avoids the phenomenon that the retaining ring position is easily offset by vibration or external force during the rotation and punching process, which would cause processing errors and affect the punching accuracy.

[0029] In one embodiment, see Figure 1 and Figure 2 As shown, a rubber layer 531 is provided on the upper part of the inner clamping plate 53. The rubber layer 531 increases the friction, ensuring that the retaining ring 100 to be processed will not slip or loosen during the clamping process, further improving the stability of the processing. The rubber layer 531 avoids direct contact between the inner clamping plate 53 and the inner ring of the retaining ring, effectively preventing scratches, indentations and other problems, and ensuring the appearance and performance of the retaining ring.

[0030] In one embodiment, see Figure 3 and Figure 2As shown, the punching assembly 6 comprises a punching frame body 61, a hydraulic cylinder 62 is arranged above the punching frame body 61, the hydraulic cylinder 62 is slidingly connected to the upper portion of the punching frame body 61, the hydraulic cylinder 62 can slide back and forth along the direction of the punching frame body 61 through a reciprocating screw rod assembly or an electric sliding mechanism (not shown in the figure), and the specific hydraulic cylinder 62 can slide back and forth along the direction of the punching frame body 61, and in the embodiment, a reciprocating screw rod driving mechanism, a reciprocating screw rod and a screw nut are arranged in the punching frame body 61, the reciprocating screw rod is rotatably connected in the punching frame body 61, the screw nut is threadedly connected to the reciprocating screw rod, and the upper portion of the screw nut is fixedly connected with the hydraulic cylinder 62, a driving source is arranged in the punching frame body 61, the reciprocating screw rod is driven to rotate by the driving source, the hydraulic cylinder 62 fixed to the screw nut reciprocates to adapt to the punching requirement of the different size inner diameter check ring, a punching head 63 is arranged at the telescopic end of the hydraulic cylinder 62, a locking assembly 7 is arranged below the punching frame body 61, the hydraulic cylinder 62 drives the punching head 63 to move up and down to complete the punching operation of the check ring 100 to be processed, and the punching speed and pressure are accurately adjusted through a hydraulic control system to meet different processing requirements. The locking assembly 7 is arranged below the punching frame body 61, and is used for fixing the position of the rotating table 42 and the check ring 100 to be processed. Through the cooperation of the locking block 73 and the locking groove 421 of the rotating table 42, the locking assembly 7 provides the necessary stability during the punching process, and prevents the check ring 100 to be processed from being displaced or rotated due to impact force.

[0031] In one embodiment, as shown in Figure 3 , Figure 1 and Figure 4 Figure 1 Figure 2 Figure 3 , the support plate 71 is fixed on the rack 1, and is used for supporting and mounting the second electric push rod 72 and the locking block 73, so as to ensure the stability and accuracy of the locking assembly 7. The second electric push rod 72 controls the position of the locking block 73 through its telescopic movement. When the second electric push rod 72 is extended, the locking block 73 is inserted into the locking groove 421 of the rotating table 42, so as to realize the locking of the rotating table 42. When the second electric push rod 72 is retracted, the locking block 73 exits the locking groove 421, so as to allow the rotating table 42 to continue to rotate. The size and shape of the locking block 73 and the locking groove 421 are matched. After the locking block 73 is inserted into the locking groove 421, the rotating table 42 can be effectively fixed, so as to prevent the rotating table 42 from being displaced due to external force or vibration during the punching process.
