Description

Technical Field

[0001] The utility model relates to the technical field of assembly machines, and particularly to a manipulator for a mechanical seal assembly machine. Background Technique

[0002] Manipulators are widely used in various automated assembly devices to transfer various components to the assembly stations. The structure of existing manipulators basically uses a displacement cylinder and adds a finger cylinder. The cylinder body of the finger cylinder is fixed on the push rod of the displacement cylinder. During operation, first, the finger cylinder is above the component to be transported, then the finger cylinder acts to clamp the component and retracts. After that, the displacement cylinder pushes its push rod to move the finger cylinder above the working station to be processed, and then the finger cylinder acts to place the component on the station, thus completing the transportation.

[0003] In the production process of existing mechanical seals, it is usually necessary to assemble four components, namely a housing, a rubber ring, a graphite ring, and a retaining ring, into a complete seal. Existing assembly machines use manipulators to grasp and place these components. Since these components are circular rings, the housing is made of thin iron sheet, and the graphite ring is relatively fragile. The rectangular finger cylinder of the traditional manipulator has a limited contact area with the circular ring components during grasping, and the contact pressure is relatively large, often resulting in the deformation of the housing and the fragmentation of the graphite ring. Therefore, a manipulator for a mechanical seal assembly machine is proposed to solve the problems mentioned above. Content of the Utility Model

[0004] To solve the above technical problems, a manipulator for a mechanical seal assembly machine is provided. This technical solution solves the problem that in the production process of existing mechanical seals, it is usually necessary to assemble four components, namely a housing, a rubber ring, a graphite ring, and a retaining ring, into a complete seal. Existing assembly machines use manipulators to grasp and place these components. Since these components are circular rings, the housing is made of thin iron sheet, and the graphite ring is relatively fragile. The rectangular finger cylinder of the traditional manipulator has a limited contact area with the circular ring components during grasping, and the contact pressure is relatively large, often resulting in the deformation of the housing and the fragmentation of the graphite ring.

[0013] The beneficial effects of the present utility model compared with the prior art are:

[0014] This solution proposes a manipulator for a mechanical seal assembly machine. By opening an arc-shaped groove on the clamping plate and setting a damping spring shock absorber and a gasket, the damage to the components during the clamping process is reduced. The arc-shaped groove design matches the surface of the components, avoiding point contact, being able to disperse the pressure applied to the components, reducing local stress concentration, and reducing the risk of component deformation or damage. The gasket increases the flexibility of the grasping contact surface, being able to reduce the extrusion on the components. The damping spring shock absorber can absorb the impact and vibration generated during the clamping process, provide a buffering effect, reduce the impact force during the clamping process, avoid sudden impact damage to the components, make the clamping process smoother, reduce the pressure change of the manipulator on the components, protect vulnerable components, and improve the clamping accuracy and operation consistency through a stable buffering effect.

[0021] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0022] Referring to Figures 1-4 As shown, a manipulator for a mechanical seal assembly machine includes a base 1. The upper end of the base 1 is rotatably connected to a rotating seat 2. The upper end of the rotating seat 2 is rotatably connected to a support frame 3. A chute 4 is opened at the right end of the support frame 3. A lead screw 5 is rotatably connected inside the chute 4. A first motor 6 for driving the rotation of the lead screw 5 is fixedly installed at the upper end of the support frame 3. A sliding seat 7 is threadedly connected to the outer surface of the lead screw 5. An electric push rod 8 is fixedly installed at the right end of the sliding seat 7. The output end of the electric push rod 8 is fixedly connected to a fixed frame 9. A finger cylinder 10 is fixedly installed inside the fixed frame 9. Two symmetrically distributed moving fingers 11 are arranged at the lower end of the finger cylinder 10. A damping spring shock absorber 12 is fixedly connected to the inner side of the moving finger 11. A clamping plate 13 is fixedly connected to the inner side of the damping spring shock absorber 12. A groove 14 is opened on the inner side of the clamping plate 13. A gasket 15 is fixedly connected inside the groove 14.

[0023] Furthermore, the damping spring shock absorber 12 can reduce the sudden impact on the component during clamping, avoid damaging the component, absorb the vibration during the operation process, ensure that the clamping process is more stable, reduce the change of the clamping force by providing a buffering effect, can protect the vulnerable components, and improve the clamping accuracy and consistency.

[0024] Furthermore, the groove 14 is arc-shaped, and the grasping surface of the clamping plate 13 is designed to be arc-shaped, matching the outer contour of the component to be grasped, so that the contact area is larger during the grasping process. By increasing the contact area of the clamping plate 13, the single-point pressure is reduced, and the pressure distribution becomes more uniform.

[0025] Furthermore, the gasket 15 is made of silicone, which has high elasticity and wear resistance, and can effectively disperse pressure and improve grasping stability.

[0026] Refer to Figure 2 As shown, the lower end of the rotating seat 2 is fixedly connected to a rotating shaft 16, and the other end of the rotating shaft 16 penetrates through the upper end of the base 1 and is rotatably connected to the inner bottom end of the base 1.

[0027] Furthermore, a second motor 18 is fixedly installed at the left end of the base 1. The output end of the second motor 18 penetrates through the left end of the base 1 and is fixedly connected to a second bevel gear 19, and the second bevel gear 19 meshes with the first bevel gear 17.

[0028] Furthermore, four uniformly distributed telescopic rods 20 are fixedly connected between the fixed frame 9 and the sliding seat 7. The four uniformly distributed telescopic rods 20 can balance various forces applied to the manipulator, preventing uneven operation or uneven clamping caused by the deviation of the force, thus ensuring the uniformity and stability of the clamping action.

[0029] Working principle: During use, the second motor 18 drives the second bevel gear 19 to rotate. The second bevel gear 19 drives the first bevel gear 17 and the rotating shaft 16 to rotate, thereby driving the rotating seat 2 to rotate, and then driving the finger cylinder 10 to rotate. At the same time, the first motor 6 drives the lead screw 5 to rotate to adjust the longitudinal position of the finger cylinder 10, and the electric push rod 8 pushes the fixed frame 9 to move to adjust the transverse position of the finger cylinder 10, so as to move the finger cylinder 10 to a suitable position. Then, the finger cylinder 10 is started, and the two moving fingers 11 are contracted. The two moving fingers 11 drive the two clamping plates 13 to approach the outer surface of the grasping component, so that the gasket 15 on the clamping plate 13 contacts the outer surface of the component to grasp the component. During the clamping process, through the mutual cooperation of the damping spring shock absorber 12, the arc-shaped groove 14 and the gasket 15, the clamping force of the two moving fingers 11 can act on the component evenly, thereby reducing the phenomenon that the contact pressure is too large due to the limited contact area between the moving fingers 11 and the ring component during the grasping process, resulting in the deformation of the outer shell and the fragmentation of the graphite ring.
