Description

Technical Field

[0001] This utility model relates to the field of assembly mechanism technology, specifically to an O-ring assembly mechanism. Background Technology

[0002] O-rings are rubber sealing rings with a circular cross-section, named for their O-shaped shape. They are among the most affordable and widely used mechanical sealing elements on the market, widely applied in various mechanical seal designs. Due to their simple manufacturing, quick installation, and strong sealing performance, O-rings are widely used in various industrial fields. Traditionally, O-ring assembly was mostly done manually. While simple and direct, this method suffers from low efficiency, high labor costs, and inconsistent assembly quality. Manual assembly also easily leads to damage or foreign matter contamination of the O-ring during installation, affecting the product's sealing performance and aesthetics. With the advancement of industrialization and the improvement of automation, the demand for O-ring assembly mechanisms is increasing. Automated assembly mechanisms can significantly improve assembly efficiency, reduce labor costs, and ensure the consistency and stability of assembly quality. Automated assembly mechanisms can also reduce the impact of human factors on product quality and improve the overall performance of the product.

[0003] Existing technologies, such as Chinese Patent Publication No. CN220863866U, describe an O-ring assembly mechanism. This existing device connects a mandrel and a push rod via a telescopic shaft of a power mechanism. The push rod connects to a push plate, and the opening end of a gripper passes through the push plate and is positioned within the inner ring of the O-ring. A ramp is provided at one end of the mandrel adjacent to the push plate, and the radially moving end of the gripper is located on one side of the ramp of the mandrel. This allows for the rapid assembly of O-rings of different models. However, this existing device requires manual installation of the O-rings onto the workpieces to be assembled, reducing work efficiency and increasing labor costs. Furthermore, manual operation can lead to inconsistent product quality.

[0004] Therefore, we propose an O-ring assembly mechanism to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an O-ring assembly mechanism to solve the problems mentioned in the background art, which require manual installation of O-rings on the workpiece to be assembled, reducing work efficiency, increasing labor costs, and causing inconsistent product quality due to manual operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an O-ring assembly mechanism. It includes a base,

[0007] A support frame is installed on the upper end of the base, and a first motor is installed on the right end of the support frame. A first reciprocating screw is connected between the support frames, and a first slider is provided on the first reciprocating screw. A first electric telescopic rod is connected to the lower end of the first slider, and a housing is connected to the lower end of the first electric telescopic rod. A chuck housing is connected to the lower end of the housing, and a chuck coil is provided on the upper end of the inner wall of the chuck housing. The chuck coil is connected to a bevel gear, and the bevel gear is connected to a second reciprocating screw. A second slider is provided on the second reciprocating screw, and a clamp is connected to the bottom end of the second slider. A push cylinder is provided at the bottom end of the housing.

[0008] A feeding platform is provided at the right end of the base, and a shelf is provided at the left end of the base.

[0009] Preferably, the support frame is rotatably connected to the first reciprocating lead screw, and the first motor is fixedly connected to the first reciprocating lead screw. The first reciprocating lead screw is threadedly connected to the first slider, and the support frame is slidably connected to the first slider.

[0010] Using the above technical solution, the first reciprocating screw is rotated by the first motor. Since the first slider is slidably connected to the support frame and the first reciprocating screw is threadedly connected to the first slider, the first slider moves horizontally when the first reciprocating screw rotates.

[0011] Preferably, a second motor is installed in the middle of the inner part of the housing, and the lower end of the second motor is fixedly connected to the chuck screw. A groove is opened in the middle of the chuck housing, and the lower end of the second motor passes through the groove. Three sets of connecting rods are equidistantly connected to the inner wall of the chuck housing, and the connecting rods are fixedly connected to the inner shell of the chuck.

[0012] Using the above technical solution, the second motor drives the chuck screw to rotate, generating power for clamping expansion and contraction.

[0013] Preferably, the lower end of the chuck screw is equidistantly connected to three sets of bevel gears, and the chuck screw meshes with the bevel gears. The bevel gears are rotatably connected to the inner shell of the chuck, and the outer end of the bevel gears is fixedly connected to the second reciprocating screw. The outer end of the second reciprocating screw is rotatably connected to the outer shell of the chuck. The second reciprocating screw is threadedly connected to the second slider, and a limit rod passes through the middle end of the second slider. The second slider is slidably connected to the limit rod, and the limit rod is fixedly connected to the outer shell and the inner shell of the chuck. The lower end of the second slider is fixedly connected to the clamp.

[0014] Using the above technical solution, the chuck pulley drives the bevel gear to rotate, and the bevel gear drives the second reciprocating screw to rotate. Because the limiting rod restricts the second slider and prevents the second slider from rotating, the second slider moves horizontally. The second slider drives the clamp to move horizontally, which plays the role of expanding and shrinking, so that the O-ring can be on the clamp. The clamp drives the O-ring to move.

[0015] Preferably, a second electric telescopic rod is installed at the left end of the inner side of the housing, and the lower end of the second electric telescopic rod is fixedly connected to the push cylinder, and the push cylinder is slidably connected to the chuck housing.

[0016] By adopting the above technical solution, the push cylinder is driven to move vertically by the second electric telescopic rod, which plays the role of detaching the O-ring from the clamp. The automated operation makes the device more convenient, reduces labor costs, improves work efficiency, and ensures product quality.

[0017] Preferably, a conveyor belt is attached to the right end of the feeding platform, and a spring telescopic rod is installed inside the feeding platform. A table is provided at the upper end of the feeding platform, and the feeding platform is slidably connected to the table, and the table is fixedly connected to the spring telescopic rod. The workpiece to be assembled is placed at the upper end of the shelf.

[0018] Using the above technical solution, the O-ring is conveyed to the feeding platform by the conveyor belt. The clamp moves above the feeding platform and presses down to pick up the O-ring to the outer end of the clamp. After the clamp rises, the spring telescopic rod restores the feeding platform. The clamp moves above the shelf and puts the O-ring onto the workpiece to be assembled, so that the device can automatically assemble and improve the production efficiency of the device.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the assembly mechanism of the O-ring;

[0020] 1. The second motor drives the chuck screw to rotate, which in turn drives the bevel gear and the second reciprocating screw to rotate, thereby moving the second slider and the gripper. This allows the gripper to expand and move the O-ring. The second electric telescopic rod drives the push cylinder to move vertically, which automatically pushes in the components to be assembled. The device assembles automatically, increases work efficiency, ensures product quality, and reduces labor costs.

[0021] 2. The conveyor belt transports the O-rings to the feeding platform to achieve automatic feeding, saving manpower and improving the working efficiency of the equipment. Attached Figure Description

[0029] Please see Figure 1-5This utility model provides a technical solution: an O-ring assembly mechanism, including a base 1, a support frame 2 mounted on the upper end of the base 1, a first motor 3 mounted on the right end of the support frame 2, a first reciprocating screw 4 connected between the support frames 2, a first slider 5 provided on the first reciprocating screw 4, a first electric telescopic rod 6 connected to the lower end of the first slider 5, a housing 7 connected to the lower end of the first electric telescopic rod 6, a chuck housing 9 connected to the lower end of the housing 7, a chuck coil screw 11 provided on the upper end of the inner wall of the chuck housing 9, a bevel gear 14 connected to the chuck coil screw 11, a second reciprocating screw 15 connected to the bevel gear 14, a second slider 16 provided on the second reciprocating screw 15, a clamp 18 connected to the bottom end of the second slider 16, and a clamp 18 provided at the bottom end of the housing 7. The device includes a pusher 20, a support frame 2 rotatably connected to a first reciprocating screw 4, a first motor 3 fixedly connected to the first reciprocating screw 4, a first reciprocating screw 4 threadedly connected to a first slider 5, and a support frame 2 slidably connected to the first slider 5. A second motor 8 is installed in the middle of the interior of the housing 7, and the lower end of the second motor 8 is fixedly connected to a chuck screw 11. A groove 10 is provided in the middle of the chuck housing 9, and the lower end of the second motor 8 passes through the groove 10. Three sets of connecting rods 12 are equidistantly connected to the inner wall of the chuck housing 9, and the connecting rods 12 are fixedly connected to the inner shell of the chuck. Three sets of bevel gears 14 are equidistantly connected to the lower end of the chuck screw 11, and the chuck screw 11 meshes with the bevel gears 14. The bevel gears 14 are rotatably connected to the inner shell of the chuck, and the outer end of the bevel gears 14 is connected to the second reciprocating screw 5. The lead screw 15 is fixedly connected, and the outer end of the second reciprocating lead screw 15 is rotatably connected to the chuck housing 9. The second reciprocating lead screw 15 is threadedly connected to the second slider 16, and a limit rod 17 passes through the middle of the second slider 16. The second slider 16 is slidably connected to the limit rod 17, and the limit rod 17 is fixedly connected to the chuck housing 9 and the chuck inner housing 13. The lower end of the second slider 16 is fixedly connected to the clamp 18. A second electric telescopic rod 19 is installed on the left end inside the housing 7, and the lower end of the second electric telescopic rod 19 is fixedly connected to the push cylinder 20. The push cylinder 20 is slidably connected to the chuck housing 9. The first reciprocating lead screw 4 is driven to rotate by the first motor 3. Because the first slider 5 is slidably connected to the support frame 2, and the first reciprocating lead screw 4 is threadedly connected to the first slider 5, the first reciprocating lead screw 4... During rotation, the first slider 5 moves horizontally, and the first electric telescopic rod 6 drives the housing 7 and the clamp 18 to move vertically.

The conveyor belt 21 transports the O-ring to the feeding platform 22. The clamp 18 moves above the feeding platform 22 and presses down to pick up the O-ring to the outer end of the clamp 18. After the clamp 18 rises, the spring telescopic rod 23 restores the feeding platform 22. The clamp 18 moves above the shelf 25 and puts the O-ring onto the workpiece 26 to be assembled, completing the automated assembly.

[0031] Working principle: When using this O-ring assembly mechanism, the conveyor belt 21 transports the O-ring to the feeding table 22. The first motor 3 drives the first reciprocating screw 4 to rotate, causing the first slider 5 to move horizontally. Simultaneously, this drives the lower first electric telescopic rod 6, the housing 7, and the clamp 18 to move, moving the clamp 18 to the upper end of the feeding table 22. The first electric telescopic rod 6 then drives the clamp 18 to move vertically, compressing the table surface 24 on the feeding table 22 and fitting the O-ring. The second motor 8 drives the chuck screw 11 to rotate, causing the bevel gear 14 to rotate, which in turn drives the second reciprocating screw 15 to rotate, causing the second slider 16 and the lower end of the clamp 18 to move horizontally, thereby expanding and shrinking the clamp 18 to clamp the O-ring. The first motor 3 moves the clamp 18 above the shelf 25, and the second electric telescopic rod 19 drives the push cylinder 20 to move vertically, pushing the O-ring onto the workpiece 26 to be assembled, thus completing the assembly of the O-ring.
