Description

Technical Field

[0001] This invention relates to the field of pin machining technology, specifically a turning mechanism for pin machining. Background Technology

[0002] As a key component in mechanical transmission, the pin is widely used in many fields such as engineering machinery, automobiles, agricultural machinery, mining equipment, rail transportation, and hoisting machinery. It is mainly used for hinged connections, torque transmission, positioning and fixing, and shaft support, and is a core basic component to ensure the reliable operation of the mechanism.

[0003] However, traditional mechanisms use rubber or silicone materials for the limiting surface when machining pins to ensure stable and damage-proof limiting. Over time, the rubber or silicone will wear out, affecting the limiting effect and requiring manual replacement by the user. There is no automatic rubber pad replacement function. After long-term use, the wear of the rubber pad will cause clamping slippage, requiring manual shutdown for replacement, further reducing the continuity of processing. Summary of the Invention

[0004] The purpose of this invention is to provide a turning mechanism for machining pins, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a turning mechanism for machining pins, comprising a platform and a second limiting member. A traveling structure is provided on one side of the platform, and a turning structure is mounted on the upper side of the traveling structure. An auxiliary frame is provided on one side of the turning structure, and a driving assembly for providing driving force is installed inside the auxiliary frame. The driving assembly includes a drive motor, a drive wheel, and a transmission wheel. The drive wheel is mounted on the output end of the drive motor. A transmission wheel is meshed on one side of the drive wheel. Connecting discs are fixedly mounted on both sides of the transmission wheel. The inner side of the transmission wheel... A hydraulic rod two is installed at the top, and a limiting component one is installed at the output end of the hydraulic rod two. The limiting component two is located below the limiting component one, and an auxiliary component for assisting the positioning of the pin is installed inside the limiting component one. The auxiliary component includes a fixed upright plate, a reel, a servo motor, a positioning plate, a side plate, and a guide shaft. A servo motor is installed on one side of the fixed upright plate, and a reel is provided at the output end of the servo motor. A rubber pad is provided on the outer surface of the reel. A positioning plate is installed between the two sets of reels, and side plates are fixedly provided on both sides of the positioning plate. A guide shaft is installed inside the side plate.

[0006] Furthermore, a fixing seat is fixedly installed at the bottom of the second limiting member, and the fixing seat has a rectangular structure.

[0007] Furthermore, the connecting plate is rotatably disposed inside the auxiliary frame, and a feeding frame is installed on one side of the auxiliary frame.

[0008] Furthermore, the inside of the feeding frame is provided with a feeding component for assisting in feeding and unloading, and the feeding component includes a fixed plate, a hydraulic rod and a push plate. The hydraulic rod is installed on one side of the fixed plate, and the output end of the hydraulic rod is provided with a push plate.

[0009] Furthermore, the feeding assembly also includes a connecting rod and an adapter rod, with connecting rods fixedly installed on both sides of the push plate, and an adapter rod fixedly connected to the bottom of the connecting rod.

[0010] Furthermore, the adapter rod has an "L"-shaped structure, and a push plate is installed at the end of the adapter rod.

[0011] Furthermore, the platform has an internal discharge port, and a collection frame is installed below the discharge port, with the collection frame slidably connected to the push plate.

[0012] Furthermore, a protective frame is installed on the upper exterior of the discharge port, and the platform is fixed to the protective frame with bolts.

[0013] This invention provides a turning mechanism for machining pins, which has the following advantages: 1. This invention achieves integrated operation of automatic feeding, precise positioning, turning, automatic unloading and collection through the coordinated linkage of feeding components, driving components and auxiliary components, replacing traditional manual operation. This not only reduces the labor intensity of operators, but also avoids errors caused by manual positioning, feeding and unloading. At the same time, the push plate can help organize the pins in the collection frame to prevent further stacking and collision.

[0014] 2. The servo motor in the auxiliary component of this invention can drive the roller to rotate. When the rubber pad wears out after long-term use, there is no need to manually stop the machine to replace it. The rubber pad can be automatically replaced by rotating the roller, ensuring that the rubber pad in contact with the pin is always in good condition. This can not only continuously ensure the clamping friction and prevent the pin from slipping, but also avoid positioning deviation caused by rubber pad wear, ensuring the continuity of turning operations, reducing downtime losses, and further improving processing efficiency.

[0017] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0018] like Figures 1-6As shown, a turning mechanism for machining pins includes a platform 1, a turning structure 2, a protective frame 3, an auxiliary frame 4, a collecting frame 5, a traveling structure 6, a discharge port 7, a push plate 8, a loading frame 9, a loading assembly 10, a fixed plate 1001, a hydraulic rod one 1002, a push plate 1003, a connecting rod 1004, an adapter rod 1005, a hydraulic rod two 11, a limiting component one 12, a limiting component two 13, a connecting plate 14, a fixed base 15, a drive assembly 16, a drive motor 1601, a drive wheel 1602, a transmission wheel 1603, an auxiliary assembly 17, a fixed upright plate 1701, a reel 1702, and a servo motor 1703. The platform 1 includes a positioning plate 1704, a side plate 1705, a guide shaft 1706, and a rubber pad 18. A traveling structure 6 is provided on one side of the platform 1, and a turning structure 2 is mounted on the upper side of the traveling structure 6. An auxiliary frame 4 is provided on one side of the turning structure 2, and a drive assembly 16 for providing driving force is installed inside the auxiliary frame 4. The drive assembly 16 includes a drive motor 1601, a drive wheel 1602, and a transmission wheel 1603. The drive wheel 1602 is mounted on the output end of the drive motor 1601, and the transmission wheel 1603 is meshed on one side of the drive wheel 1602. Connecting discs 14 are fixedly mounted on both sides of the transmission wheel 1603. The receiving plate 14 is rotatably mounted inside the auxiliary frame 4, and a feeding frame 9 is installed on one side of the auxiliary frame 4. A hydraulic rod 11 is installed on the top of the inner side of the transmission wheel 1603, and a limit member 12 is installed at the output end of the hydraulic rod 11. A limit member 13 is located below the limit member 12, and an auxiliary component 17 for assisting the positioning of the pin is installed inside the limit member 12. A fixed base 15 is fixedly installed at the bottom of the limit member 13, and the fixed base 15 has a rectangular structure. The auxiliary component 17 includes a fixed upright plate 1701, a roller 1702, a servo motor 1703, a positioning plate 1704, a side plate 1705, and a guide shaft. 1706, and a servo motor 1703 is installed on one side of the fixed plate 1701. The output end of the servo motor 1703 is provided with a scroll 1702, and a rubber pad 18 is provided on the outer surface of the scroll 1702. A positioning plate 1704 is installed between the two sets of scrolls 1702, and side plates 1705 are fixedly provided on both sides of the positioning plate 1704. A guide shaft 1706 is installed inside the side plate 1705. After the pin enters the processing area, the hydraulic rod 11 on the top of the inner side of the transmission wheel 1603 is activated, pushing the limiting member 12 to move downward and cooperate with the limiting member 13 below to initially clamp the pin from the top and bottom.Limiting component 2 13 is fixed by the bottom fixing seat 15. The fixing seat 15 has a rectangular structure, which can improve the stability of limiting component 2 13 and prevent displacement during clamping. The fixing plate 1701 provides mounting support for the servo motor 1703. After the servo motor 1703 starts, it drives the output end of the scroll 1702 to rotate. The rubber pad 18 on the outer surface of the scroll 1702 contacts the pin surface, which can increase the friction and prevent the pin from slipping during rotation, and also avoid damage to the pin surface. After a period of use, the rubber pad 18 on the surface of the positioning plate 1704 can be replaced by rotating the scroll 1702, ensuring that the rubber pad 18 in contact with the pin is undamaged and the clamping effect is stable. The rubber pad 18 is replaced automatically without manual adjustment by the user. The drive component 16 provides power for the rotation of the pin and drives the motor. After machine 1601 starts, it drives the drive wheel 1602 at the output end to rotate. The drive wheel 1602 is linked with the transmission wheel 1603 meshing on one side, driving the transmission wheel 1603 to rotate. The connecting discs 14 on both sides of the transmission wheel 1603 are rotatably set inside the auxiliary frame 4, providing support for the transmission wheel 1603 and ensuring its rotational stability. This, in turn, drives the clamped and positioned pin to rotate synchronously, providing rotational power for turning. After the pin is positioned, clamped, and begins to rotate at a constant speed, the traveling structure 6 starts, driving the turning structure 2 above it to move along one side of the platform 1, adjusting the relative position of the turning structure 2 and the pin, so that the turning tool precisely fits the pin surface. According to the preset processing parameters, the turning structure 2 performs turning processing on the rotating pin, removing excess blank material and processing a pin shape that meets the specifications.

[0019] like Figure 1 and Figure 3As shown, the loading frame 9 is internally equipped with a loading assembly 10 for assisting loading and unloading. The loading assembly 10 includes a fixed plate 1001, a hydraulic rod 1002, and a push plate 1003. The hydraulic rod 1002 is installed on one side of the fixed plate 1001, and the push plate 1003 is installed at the output end of the hydraulic rod 1002. The loading assembly 10 also includes a connecting rod 1004 and an adapter rod 1005. The connecting rod 1004 is fixedly installed on both sides of the push plate 1003, and the adapter rod 1005 is fixedly connected to the bottom of the connecting rod 1004. The adapter rod 1005 has an "L" shape, and a push plate 8 is installed at the end of the adapter rod 1005. The platform 1 has a discharge port 7 inside, and a collection frame 5 is installed below the discharge port 7. The collection frame 5 is slidably connected to the push plate 8. A protective frame 3 is installed on the outside of the discharge port 7, and the platform 1 is fixed to the protective frame 3 by bolts. The protective frame 3 above the platform 1 serves as a protective device. The safety protection function prevents iron filings from flying during turning and protects the safety of operators. The feeding operation is jointly completed by the feeding frame 9 and the feeding assembly 10. The feeding frame 9 is used to store the pin blanks to be processed. One side of it is connected to the auxiliary frame 4 to ensure that the pins can be accurately delivered to the processing station. The fixing plate 1001 in the feeding assembly 10 provides fixed support for the hydraulic rod 1002. When feeding is required, the hydraulic rod 1002 is activated, pushing the push plate 1003 at its output end to move forward. The push plate 1003 pushes the pin blank in the feeding frame 9 and makes it enter the processing positioning area in the auxiliary frame 4. At the same time, the connecting rods 1004 fixed on both sides of the push plate 1003 synchronously drive the bottom adapter rod 1005 to move. Because the adapter rod 1005 has an "L" shaped structure, the push plate 8 connected to its end will move accordingly, thereby assisting in pushing the pins that fall into the collection frame 5 after processing, and avoiding the stacking of pins.

[0020] In summary, the turning mechanism for machining the pin is first based on... Figures 1-6In the structure shown, the feeding operation is jointly completed by the feeding frame 9 and the feeding assembly 10. The feeding frame 9 is used to store the pin blanks to be processed. One side of it is connected to the auxiliary frame 4 to ensure that the pins can be accurately delivered to the processing station. The fixing plate 1001 in the feeding assembly 10 provides fixed support for the hydraulic rod 1002. When feeding is required, the hydraulic rod 1002 is activated, pushing the push plate 1003 at its output end to move forward. The push plate 1003 pushes the pin blank in the feeding frame 9, causing it to enter the auxiliary frame 4. In the processing positioning area, the connecting rods 1004 fixed on both sides of the push plate 1003 simultaneously drive the bottom adapter rod 1005 to move. Because the adapter rod 1005 has an "L" shaped structure, the push plate 8 connected to its end will move accordingly, thereby assisting in pushing the pins that fall inside the collection frame 5 after processing, preventing the pins from stacking. After the pins enter the processing area, the hydraulic rod 11 on the top of the inner side of the transmission wheel 1603 is activated, pushing the limiting member 12 downward to cooperate with the lower limiting member 13, from... The pin is initially clamped vertically. The second limiting component 13 is fixed by the bottom mounting base 15, which has a rectangular structure to improve the stability of the second limiting component 13 and prevent displacement during clamping. The fixed plate 1701 provides mounting support for the servo motor 1703. After the servo motor 1703 starts, it drives the output shaft 1702 to rotate. The rubber pad 18 on the outer surface of the shaft 1702 contacts the pin surface, increasing friction to prevent slippage during rotation and avoiding damage. The surface of the pin shaft can be rotated by the roller 1702 after a period of use, so that the rubber pad 18 on the surface of the positioning plate 1704 can be replaced, ensuring that the rubber pad 18 in contact with the pin shaft is undamaged, stabilizing the clamping effect. The rubber pad 18 can be replaced automatically without the need for manual adjustment by the user. The drive component 16 provides power for the rotation of the pin shaft. After the drive motor 1601 starts, it drives the drive wheel 1602 at the output end to rotate. The drive wheel 1602 is linked with the transmission wheel 1603 meshing on one side, driving the transmission wheel 1603 to rotate.The connecting discs 14 on both sides of the transmission wheel 1603 are rotatably mounted inside the auxiliary frame 4, providing support for the transmission wheel 1603 and ensuring its rotational stability. This, in turn, drives the clamped and positioned pin to rotate synchronously, providing rotational power for turning. After the pin is positioned, clamped, and begins to rotate at a constant speed, the traveling structure 6 is activated, driving the turning structure 2 above it to move along one side of the platform 1. The relative position of the turning structure 2 and the pin is adjusted so that the turning tool precisely fits the pin surface. According to the preset processing parameters, the turning structure 2 performs turning processing on the rotating pin, removing excess blank material and machining a pin shape that meets specifications. During the processing, the protective frame 3 above the platform 1 provides safety protection to prevent damage during the turning process. Metal filings fly, protecting operator safety. After the pin is machined, hydraulic rod 11 retracts, causing limiter 12 to move upward, releasing the clamp on the pin. Drive assembly 16 stops working, and the pin stops rotating. At this time, loading assembly 10 activates again, and hydraulic rod 1002 continues to push push plate 1003. Through connecting rod 1004 and adapter rod 1005, push plate 8 moves, pushing the machined pin towards the unloading port 7 inside platform 1. The pin falls through unloading port 7 into the collection frame 5 installed below. Collection frame 5 is slidably connected to push plate 8 and can be adjusted in position as push plate 8 moves, ensuring the pin falls accurately into collection frame 5, achieving centralized collection of finished products for subsequent sorting and transportation.
