Description

Technical Field

[0002] The stainless steel double-buckle tube installed on the outside of the flexible hose body is used to protect the inner tube of the hose to prevent corrosion and aging. Since the double-buckle tube has good flexibility, it can bend and rotate with the inner tube and is flexible to use. The hose body generally used in faucets, sanitary ware, and shower water connections mostly adopts a stainless steel double-buckle structure, which can be bent and rotated with the inner tube. The stainless steel tube body is bright and neat and is deeply loved by consumers.

[0003] The double-buckle hose generally includes an inner tube, a metal bellows, and an inner and outer seals arranged at the ends of the two. The metal bellows is sleeved on the outside of the inner tube, and the outer seal is tightly sleeved on the outside of the metal bellows. The inner seal is located between the inner tube and the metal bellows, and one end of the inner seal and the outer seal are both provided with a horn interface. The end of the inner tube is also inserted into the inner plug through interference fit, and the inner plug needs to be interference matched with the inner seal. After the inner plug is pressed into the inner seal, the outer wall of the inner seal is pressed outward against the inner wall of the metal bellows, thereby forming a clamping structure to prevent the metal bellows, the inner seal and the inner plug from falling off.

[0004] The existing inner plug is manually inserted into the inner tube, and then manually sent to a small punch to buckle and press the inner plugs at both ends. The inner plug assembly of the double buckle hose is currently done manually, which is inefficient and poor in assembly uniformity, which will cause problems in subsequent use.

[0049] Example

[0050] See attached Figure 1-2A double-buckle hose 1 comprises an inner tube 11, a metal bellows 12, and an inner sleeve 13 and an outer sleeve 14 arranged at the ends of the inner tube 11 and the metal bellows 12. The inner tube 11 is made of plastic material, the metal bellows 12 is sleeved on the outside of the inner tube 11, and the outer sleeve 14 is tightly sleeved on the outside of the metal bellows 12. The inner sleeve 13 is located between the inner tube 11 and the metal bellows 12, and can slide along the inner tube 11 when not fixed. One end of the inner sleeve 13 and the outer sleeve 14 are both provided with a horn interface. The end of the inner tube 11 is also inserted with an inner plug 15 inserted therein by interference fit. The inner plug 15 needs to be interference matched with the inner sleeve 13 and the metal bellows 12. After the inner plug 15 is pressed in the inner sleeve 13, the outer wall of the inner sleeve 13 is pressed outward against the inner wall of the metal bellows 12, thereby forming a clamping structure to prevent the metal bellows 12, the inner sleeve 13 and the inner plug 15 from falling off. The inner plug 15 includes an interference fit portion and a flat abutment portion. The interference fit portion is inserted into the inner tube 11 to be interference matched with the inner seal 13, and the flat abutment portion abuts against the outside of the horn interface of the outer seal 14. The inner plug 15 assembly system is to install the inner plug 15 in the inner tube 11, and press the inner plug 15 and the inner seal 13 by interference fit, so as to realize the automatic assembly of the double-buckle hose 1 and the inner plug 15.

[0051] See attached Figure 1 As shown, a double-buckle hose inner plug assembly system of the present invention comprises a frame 2, a mounting plate 21 is arranged on the frame 2, a conveying mechanism 200 is arranged in the frame 2, and a feeding mechanism 300, a heating mechanism 400, an inner plug installation mechanism 500, a pipe arrangement mechanism 600, a riveting mechanism 700, an airtightness detection mechanism 800 and a feeding mechanism 900 are sequentially arranged on the frame 2. The feeding mechanism 300 is used to straighten the inner tube 11 of the double-buckle hose 1, and clamp the end of the inner tube 11 vertically upward and convey it to the conveying mechanism 200. The conveying mechanism 200 clamps the end of the hose vertically upward, and sequentially transmits it to the heating mechanism 400, the inner plug installation mechanism 500 and the pipe arrangement mechanism 600, and clamps the metal bellows 12 of the double-buckle hose 1 that has been arranged by the pipe arrangement mechanism 600, and conveys the metal bellows 12 to the subsequent riveting mechanism 700, the airtightness detection mechanism 800 and the feeding mechanism 900.

[0052] The heating mechanism 400 heats the end of the inner tube 11 to facilitate the subsequent insertion of the inner plug 15. The inner plug installation mechanism 500 presses the inner plug 15 delivered by the inner plug 15 feeding mechanism 100 arranged on the outside of the frame 2 into the port of the inner tube 11. The management mechanism 600 is used to push the end of the inner tube 11 after the inner plug 15 is inserted and press it against the end of the metal bellows 12. The management mechanism 600 includes a fixing device and a moving device 6b. The fixing device can fix the metal bellows 12, and the moving device 6b can drive the inner tube 11 to move up and down and press the inner tube 11 against the end of the bellows; the riveting mechanism 700 is used for riveting the inner plug 15 and the metal bellows 12. The airtightness detection mechanism 800 performs an airtightness inspection on the assembled double buckle hose 1, and sends the tested double buckle hose 1 out of the assembly system through the unloading mechanism 900.

[0053] See attached Figure 4 As shown, the conveying mechanism 200 includes a moving part, and the moving part includes a sixth pneumatic clamp 2a corresponding to the above-mentioned processing mechanisms. The sixth pneumatic clamp 2a can move back and forth along the conveying direction of the double-buckle hose 1. The frame 2 is provided with a conveying cylinder 2b that drives the sixth pneumatic clamp 2a to move back and forth. The sixth pneumatic clamp 2a is fixed on a slide. The conveying cylinder 2b pushes the slide to move back and forth. The frame 2 is provided with a slide rail for guiding the slide. The sixth pneumatic clamp 2a is located on one side of the double-buckle hose 1, and the opening angle is 180°, which will not cause obstruction to the double-buckle hose 1 when it is processed by each processing mechanism. When the double-buckle hose 1 is processed in each processing mechanism, the sixth pneumatic clamp 2a is in an open state.

[0054] See attached Figure 6 As shown, the feeding mechanism 300 includes a first stand 3a fixed on the mounting plate 21, a first lifting cylinder 3b and a first mounting plate 3c fixed to the first lifting cylinder 3b are fixed on the first stand 3a, two first pneumatic clamps 3d are fixed on the first mounting plate 3c, and the first pneumatic clamps 3d are fixed on the lower end surface of the first mounting plate 3c. A straightening needle 3e capable of being inserted into the inner tube 11 is also vertically arranged on the first mounting plate 3c, and the center line of the straightening needle 3e coincides with the center line of the first pneumatic clamp 3d; the straightening needle 3e can move up and down along the first mounting plate 3c, a through hole is arranged on the first mounting plate 3c for the straightening needle 3e to pass through, and the straightening needle 3e is provided with stop blocks 31e located at the upper and lower sides of the through hole respectively, and the distance between the two stop blocks 31e is greater than the thickness of the first mounting plate 3c, and a contact sensor 3f capable of abutting against the top of the straightening needle 3e is also fixed on the first mounting plate 3c. There is a gap between the contact sensor 3f and the straightening needle 3e, and the contact sensor 3f is communicatively connected with the first pneumatic clamping jaw 3d.

[0055] When feeding, the first lifting cylinder 3b drives the two first pneumatic clamps 3d to the high point. At this time, the guide pin 3e is located at the upper limit block 31e under the action of gravity and abuts against the first mounting plate 3c. The operator holds the two ends of the inner tube 11 and pushes the inner tube 11 upward along the guide pin 3e. The lower end of the guide pin 3e is a conical structure, which is convenient for inserting the inner tube 11. The diameter of the guide pin 3e is smaller than the inner diameter of the inner tube 11. After the end of the inner tube 11 abuts against the limit block 31e located below the through hole, the guide pin 3e is pushed to move upward. After the guide pin 3e abuts against the contact sensor 3f, the first pneumatic clamp 3d is actuated to clamp the inner tube 11. The first lifting cylinder 3b then drives the first pneumatic clamp 3d to move downward, and vertically conveys the inner end downward to the working range of the conveying device. After the conveying device clamps the inner tube 11, the first pneumatic clamp 3d is released and moves upward under the drive of the first lifting cylinder 3b.

The second clamping device 4a includes two symmetrically arranged fourth horizontal cylinders 42a fixed on the mounting plate 21 and the first clamping plate 41a. The first clamping plate 41a is fixed to one side of the mounting plate 21 through a U-shaped first connecting frame 43a. The first clamping plate 41a is at the same height as the mounting plate 21, and there is a gap between the two for the inner tube 11 to pass through. The output shaft of the fourth horizontal cylinder 42a is fixed with a fourth clamping block 44a facing the gap, and the opposite surfaces of the two opposite fourth clamping blocks 44a are provided with triangular zone notches.

[0057] The heating device 4b includes a second vertical frame 41b fixed on the mounting plate 21, and a third lifting cylinder 42b is fixed on the second vertical frame 41b. The output shaft of the third lifting cylinder 42b is fixed with a heating rod 43b corresponding to the second clamping device 4a. The heating rod 43b can abut against the end of the inner tube 11 and heat the end of the inner tube 11. The lower end of the heating rod 43b is a frustum structure that can extend into the inner tube 11. The end of the inner tube 11 can be heated to remove the bell mouth, making it easier to insert the inner plug 15.

[0058] See attached Figure 5As shown, the inner plug feeding mechanism 100 conveys the inner plugs 15 one by one to the working range of the first clamping device 5a, and includes a vibrating loading tray 1a fixed on one side of the frame 2, and two conveying tracks 1b are arranged on the vibrating loading tray 1a, and a screening component 1c corresponding to it is arranged on one side of each conveying track 1b.

The inner plug 15 transported by the conveying track 1b enters the feed port 121c. At this time, the rodless cylinder 11c pushes the screen plate 12c to move, so that the limit plate 122c blocks the outlet of the conveying track 1b. At this time, the feed port 121c with an inner plug 15 placed enters the 500 working range of the inner plug 15 plugging mechanism.

[0059] See attached Figure 8-9 As shown, the inner plug installation mechanism 500 is divided into two groups, which are arranged corresponding to the two conveying tracks 1b, and can simultaneously insert two inner plugs 15 into the two ends of an inner tube 11.
