Description

Technical Field

[0001] This utility model relates to the field of automated assembly equipment technology, specifically to a motor rotation assembly lock ring machine. Background Technology

[0002] The assembly of traditional lock rings (such as key rings) and lock pins mainly relies on manual operation: workers must first use tools to pry open the overlapping rings on the lock ring, then manually insert the lock pin through the hole into the lock ring ring, and finally rotate the lock ring to fully embed the lock pin. This method has significant drawbacks: 1. Low efficiency: The manual separation of the locking ring and the rotating connection are cumbersome and time-consuming, making it difficult to meet the needs of mass production; 2. Poor consistency: Uneven manual force application can easily lead to deformation of the lock ring or improper engagement of the lock pins, resulting in a low product qualification rate; 3. High labor intensity: Repetitive operations can easily lead to worker fatigue and increase labor costs.

[0003] Therefore, there is an urgent need for an automated device for assembling lock rings and lock pins that can solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a motor-driven rotary assembly lock ring machine. It utilizes a three-point rotating body layout to apply force evenly, preventing lock ring rotation jamming. A tapered insert and cylinder drive precisely separate the overlapping lock rings. Efficient and controllable automated assembly is achieved through independent dual-motor drive.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A motor-driven lock ring assembly machine includes a frame, and a fixture plate, a first drive cylinder, a second drive cylinder, a first drive motor, and a second drive motor mounted on the frame. The fixture plate is fixed to the frame table and has a lock ring positioning groove and a driven rotating body. The first drive cylinder and the second drive cylinder are respectively fixed to the front and rear sides of the fixture plate, and the output end of the first drive cylinder is connected to a insert. The first drive motor is fixed below the frame table, and its output end is connected to the first rotating body. The second drive motor is mounted on the output end of the second drive cylinder, and its output end is connected to the second rotating body. The first rotating body, the second rotating body, and the driven rotating body are distributed around the lock ring positioning groove. The first rotating body and the second rotating body are driven to rotate by the first drive motor and the second drive motor, respectively, and the three together abut against the lock ring and drive it to rotate.

[0006] Furthermore, the front end of the insert is provided with a tapered end. Under the drive of the first driving cylinder, the insert is inserted horizontally into the gap between the two circular rings on the lock ring, separating the circular rings and causing the end of the lock ring to curl up.

[0007] Furthermore, the first rotating body, the second rotating body, and the driven rotating body are all made of rubber.

[0008] Furthermore, the driven rotating body is mounted on the fixture plate via bearings and cooperates with the first rotating body to form a radial stop structure against the locking ring.

[0009] Furthermore, the second rotating body moves horizontally toward or away from the fixture plate under the drive of the second drive cylinder.

[0010] Furthermore, the first and second rotating bodies rotate synchronously in the same direction, driving the locking ring to rotate within the locking ring positioning groove.

[0011] Furthermore, the shape of the locking ring positioning groove matches the outer contour of the locking ring.

[0012] Compared with existing technologies, the technical solution of this patent has the following advantages: 1. By combining the insert with the horizontal drive of the first drive cylinder, precise and reliable insertion into the gaps between the two rings on the lock ring is achieved. The tapered end design facilitates the separation of the overlapping rings and guides the end to tilt upwards, creating conditions for the subsequent insertion of the locking pin. This is significantly superior to manual operation and improves the efficiency of the separation action.

[0013] 2. The jig plate provides a stable reference, and three rotating bodies are distributed around the locking ring positioning groove, forming a three-point layout for uniform force application and drive. This ensures that the locking ring is subjected to balanced force during rotation, effectively preventing jamming. The design of two independent drive motors provides a precise and controllable rotational power source, quickly and completely fitting the locking pin onto the locking ring. This effectively solves the problems of low efficiency, poor accuracy, and easy damage in manual locking ring assembly, achieving a highly efficient, stable, and reliable automated assembly process.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] See Figure 1-5 As shown, this embodiment provides a motor-driven rotating assembly lock ring machine, including a frame 1, and a fixture plate 2, a first drive cylinder 3, a second drive cylinder 4, a first drive motor 5, and a second drive motor 6 mounted on the frame 1. The fixture plate 2 is fixed on the frame table 11, and has a lock ring positioning groove 12 and a driven rotating body 9. The first drive cylinder 3 and the second drive cylinder 4 are respectively fixed on the front and rear sides of the fixture plate 2, and the output end of the first drive cylinder 3 is connected to an insert 10. The first drive motor 5 is fixed below the frame table 11, and its output end is connected to the first rotating body 7. The second drive motor 6 is mounted on the output end of the second drive cylinder 4, and its output end is connected to the second rotating body 8. The first rotating body 7, the second rotating body 8, and the driven rotating body 9 are distributed around the outer periphery of the lock ring positioning groove 12. The first rotating body 7 and the second rotating body 8 are driven to rotate by the first drive motor 5 and the second drive motor 6, respectively, and the three together abut against the lock ring 13 and drive it to rotate. The fixture plate 2 provides a stable reference, and three rotating bodies are distributed around the locking ring positioning groove 12, forming a layout with uniform force and drive at three points. This structure ensures that the locking ring 13 is subjected to balanced force during rotation, effectively preventing jamming. The design of two independent drive motors provides a precise and controllable rotational power source. In this embodiment, the first drive cylinder 3 and the second drive cylinder 4 are both three-bar cylinders; the first drive motor 5 and the second drive motor 6 are both DC motors; all the drive cylinders and drive motors are connected to the control box 16.

[0018] The insert 10 has a tapered end 15 at its front end. Driven by the first drive cylinder 3, the insert 10 is inserted horizontally into the gap between the two rings 131 on the lock ring 13, separating the rings 131 and causing the end of the lock ring to tilt upwards. The tapered end 15 at the front end of the insert 10, combined with the horizontal drive of the first drive cylinder, achieves precise and reliable insertion into the gap between the two rings 131 on the lock ring 13. The tapered design facilitates the separation of the overlapping rings 131 and guides the end to tilt upwards, creating conditions for the subsequent insertion of the locking pin 14. The cylinder drive ensures that the force, speed, and stroke of the action are controllable and consistent, significantly superior to manual operation, and improves the efficiency of the separation action.

[0019] The first rotating body 7, the second rotating body 8, and the driven rotating body 9 are all made of rubber. The use of rubber in the first, second, and driven rotating bodies provides a high coefficient of friction and good elasticity at the contact surface with the locking ring 13. This ensures sufficient friction during drive rotation while effectively buffering contact impacts and preventing rigid contact from scratching the locking ring surface.

[0020] The driven rotating body 9 is mounted on the fixture plate 2 via bearings and cooperates with the first rotating body 7 to form a radial stop structure for the locking ring 13. The driven rotating body 9, mounted via bearings, can rotate freely under load, reducing the sliding friction resistance between it and the locking ring. The radial stop structure formed by it and the first rotating body 7 provides crucial radial positioning and constraint during the rotation of the locking ring 13, preventing the locking ring 13 from dislodging from the predetermined positioning groove due to centrifugal force or uneven force, thus significantly improving rotational stability.

[0021] The second rotating body 8, driven by the second driving cylinder 4, moves horizontally towards or away from the fixture plate 2. The second rotating body 8 is installed at the output end of the second driving cylinder 4, enabling it to move horizontally towards or away from the fixture plate. This achieves rapid clamping and release of the locking ring. Before assembly, the cylinder drives the second rotating body 8 to approach, pressing the locking ring 13 against the first rotating body 7 and the driven rotating body 9, forming a stable three-point clamping state. After assembly, the cylinder drives it away, facilitating rapid workpiece handling and improving equipment cycle time and automation.

[0022] The first rotating body 7 and the second rotating body 8 rotate synchronously and in the same direction, driving the locking ring 13 to rotate within the locking ring positioning groove 12. This ensures that the driving force applied to the circumference of the locking ring is consistent and coordinated. The shape of the locking ring positioning groove 12 matches the outer contour of the locking ring 13, providing precise initial positioning for the locking ring.

[0023] Working principle: The first drive cylinder 3 pushes the insert 10 horizontally into the gap between the two rings 131 on the lock ring 13. The conical end 15 separates the overlapping rings 131 and causes the end of the lock ring to curl up. Manually or by robotically, the locking pin 14 is inserted through the hole 141 into the curled end of the lock ring. The second drive cylinder 4 pushes the second rotating body 8 towards the fixture plate 2, pressing the lock ring 13 against the first rotating body 7 and the driven rotating body 9, forming a three-point clamping. The insert 10 is removed from the lock ring. The first drive motor 5 and the second drive motor 6 rotate synchronously in the same direction, driving the first rotating body 7 and the second rotating body 8 to rotate the lock ring 13 in the positioning groove through friction. The driven rotating body 9 follows suit. The rotation of the lock ring 13 causes the locking pin 14 to be fully inserted, the first rotating body 7 returns to its original position, and the finished product is removed. The next cycle begins.
