Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring assembly, and particularly relates to a medical hose washer installation device. Background Art

[0002] A washer is a small component commonly used in mechanical connections, generally a flat ring. Its main function is to buffer, isolate, seal, etc. between two fastening objects to ensure the stability, sealing and reliability of the fasteners. In the prior art, the installation of washers for medical hoses is mostly carried out by workers using an expansion pliers to expand the washer and then inserting the hose to complete the installation. Manual installation is prone to fatigue and has low efficiency.

[0003] Patent No. CN202220938083.9 discloses a sealing ring picking and placing device, including a lifting cylinder, a four-jaw cylinder, a sealing ring chuck, and a stripping plate. The upper part of the lifting cylinder is fixedly installed on a cylinder mounting plate. Cylindrical support columns are arranged on both sides of the cylinder mounting plate. The bottom of the support column is connected to the stripping plate. The output end of the lower part of the lifting cylinder is connected to a connecting plate. The four-jaw cylinder is connected below the connecting plate. The sealing ring chuck is connected below the four-jaw cylinder. A limiting block is installed at the lower part of the four-jaw cylinder. When in use, the staff places the required sealing ring under the device. After starting, the lifting cylinder extends downward, pushing the sealing ring chuck to below the stripping plate. At this time, the sealing ring chuck extends into the inner ring of the sealing ring, and the four-jaw cylinder opens, driving the sealing ring chuck to move outward to expand the sealing ring to achieve picking. After picking the sealing ring, the device is moved to the corresponding position of the workpiece to be installed. The lifting cylinder rises and returns to its original position. The stripping plate blocks the sealing ring and it falls into the external installation position of the part. The four-jaw cylinder retracts to achieve stripping. The efficiency of manually placing the sealing ring is low. Therefore, the utility model proposes a medical hose washer installation device. Summary of the Utility Model

[0015] Embodiment:

[0016] As Figures 1 to 3 shown, a medical hose gasket installation device of the present utility model includes a base 1 and a lifting cylinder 2 vertically arranged on the base 1. A four-jaw finger cylinder 3 is arranged on the top rod of the lifting cylinder 2. A spreading needle 4 is fixed on the finger of the four-jaw finger cylinder 3. A stripping plate 5 is arranged above the four-jaw finger cylinder 3. A mounting hole 6 for the catheter to pass through is arranged at the middle position of the stripping plate 5. A spreading needle avoidance groove 7 distributed in a cross shape with the mounting hole 6 as the center is arranged on the stripping plate 5. It is characterized in that: a gasket feeding mechanism is arranged above the stripping plate 5. The gasket feeding mechanism includes an L-shaped plate 8 with the horizontal part facing upwards. The upper end surface of the horizontal part of the L-shaped plate 8 is provided with a guide groove 9. The guide groove 9 forms an opening on the left side surface of the horizontal part of the L-shaped plate 8. The bottom surface of the guide groove 9 is provided with a gap 10 along its length direction. The guide groove 9 is connected with a gasket feeding mechanism. The lifting cylinder 2 is connected with a translation driving mechanism for driving the cylinder to slide along the length direction of the guide groove 9. The feeding mechanism feeds the gasket along the guide groove 9 to the opening. The translation driving mechanism drives the four-jaw finger cylinder 3 to move inwards until the spreading needle 4 moves below the gasket. The lifting cylinder 2 drives the four-jaw finger cylinder 3 to rise. The spreading needle 4 passes through the gasket. The translation driving mechanism drives the four-jaw finger cylinder 3 to slide outwards, and then takes the gasket out of the guide groove 9. At the same time, the four-jaw finger cylinder 3 drives the four spreading needles 4 to spread outwards, thereby expanding the gasket. The catheter is inserted into the expanded gasket. The lifting cylinder 2 drives the four-jaw finger cylinder 3 to descend. The four-jaw finger cylinder 3 drives the four spreading needles 4 to contract. With the cooperation of the stripping plate 5, the gasket falls off onto the catheter

[0017] The washer feeding mechanism includes a blanking pipe 11 vertically arranged above the guiding groove 9. The lower end surface of the blanking pipe 11 is flush with the upper end surface of the L-shaped plate 8. A pushing plate 12 is slidably connected in the guiding groove 9. One end of the pushing plate 12 is connected with a pushing cylinder 13, and the other end of the pushing plate 12 is arc-shaped. Washers are stacked in the blanking pipe 11. In the initial state, the washer at the lowermost position is in the guiding groove 9, the pushing plate 12 is behind the washer, and the depth dimension of the guiding groove 9 is consistent with the diameter dimension of the washer, ensuring that only one washer falls into the guiding groove 9 at a time. The pushing cylinder 13 pushes the current washer forward along the guiding groove 9 to the opening. The remaining washers are blocked by the upper end surface of the pushing plate 12. After the pushing is completed, the pushing plate 12 resets, and the washer at the lowermost end of the blanking pipe 11 falls into the guiding groove 9.

[0018] The translation driving mechanism includes a movable plate 14 slidably connected to the base 1 through a slide rail. The movable plate 14 is connected with a translation cylinder, and the translation cylinder is a rodless cylinder 15. The lifting cylinder 2 is fixed on the upper end surface of the movable plate 14.

[0019] A limiting plate 16 is arranged below the stripping plate 5. A cross-shaped avoidance groove 17 is arranged in the middle of the limiting plate 16. A plurality of guide rods 18 are vertically fixed on the lower end surface of the stripping plate 5. The limiting plate 16 is movably sleeved on the guide rods 18. A lead screw 19 parallel to the guide rods 18 is arranged on the lower end surface of the stripping plate 5. The lead screw 19 is connected with a servo motor 20. The limiting plate 16 is connected with the lead screw 19 through a lead screw nut. The servo motor 20 drives the lead screw 19 to rotate, so as to adjust the distance between the limiting plate 16 and the stripping plate 5. After the conduit is inserted into the mounting hole 6, it is blocked by the limiting plate 16, so that the washer can be stripped to the specified position on the conduit, ensuring the accuracy of installation.

[0020] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
