Description

Technical Field

[0001] This invention relates to a bellows support ring installation fixture, belonging to the technical field of bellows installation fixtures. Background Technology

[0002] After the corrugated pipe is manufactured and molded from the plastic body, a support ring is installed in the mounting groove inside the corrugated pipe to increase its strength. This is similar to the support ring disclosed in Chinese Patent Publication No. CN216743237U; see also: Support ring 22 installed in the mounting groove inside the corrugated pipe 21. Figure 5 As shown.

[0003] Because the support ring is an open ring-shaped component, such as Figure 6 As shown, the existing method involves manually squeezing and misaligning the support ring at the opening into the mounting groove inside the bellows. After being placed in, the support ring expands outward due to its elastic deformation. Although this method can install the support ring into the bellows, the installation efficiency is low because the line of sight is obstructed when multiple support rings are inserted into the mounting grooves inside the bellows by hand. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a bellows support ring installation fixture.

[0005] The present invention is achieved through the following technical solutions.

[0006] The present invention provides a bellows support ring installation fixture, comprising:

[0007] The mounting fixture achieves the following: after the support ring retracts into the annular groove of the core, it pre-aligns with the mounting groove inside the bellows, and when the core is pulled out, multiple support rings expand outward together to be installed into the mounting groove inside the bellows.

[0008] Includes: connecting rods;

[0009] The core has a through hole in the middle and an annular groove on the outside of the core. The annular groove is a plurality of grooves that are spaced apart on the outer periphery of the core. The core is fixed on the connecting rod.

[0010] The core has a through hole, and the core has a blocking through hole for the core to pass through. The through hole is located on the core at the outer radial position of the annular groove, so that after the core passes through the core blocking through hole, the inwardly retracted support ring can be limited in multiple annular grooves.

[0011] It also includes a sleeve with an internal sliding through hole that can be slidably installed outside the core. The sleeve is slidably fitted outside the core and can press the support ring inward.

[0012] The two ends of the connecting rod are square.

[0013] It also includes a base plate, on which support blocks are fixedly installed at intervals at both ends.

[0014] The support block is provided with square grooves for placing and engaging with the square bodies at both ends of the connecting rod to prevent rotation.

[0015] The core shaft end face has a ring-shaped limiting step for blocking one end of the bellows; the connecting rod is fitted with a ring-shaped stop block, and the stop block has a through hole in the middle and is fitted onto the connecting rod.

[0016] The stop block is held against the other end face of the core by a limiting pin, and the stop block blocks the other end of the bellows.

[0017] The core is formed by the combination of a lower lobe core and an upper lobe core. The lower lobe core and the upper lobe core are installed in a limited position by a limiting rod. The lower lobe core and the upper lobe core are fixed and wrapped around the connecting rod by screws, so that the core is fixed and wrapped around the connecting rod by screws.

[0018] The beneficial effects of this invention are as follows: The support ring is manually retracted into the annular groove. The sleeve slides outside the core, pressing the support ring as it retracts to release the hand. The core passes through the blocking through-hole of the core and into the through-hole at the opening of the support ring, preventing the support ring from expanding outwards. When the support ring is fully embedded in the annular groove of the core, the sleeve detaches from the core. The bellows is fitted onto the outside of the core, and the stop block abuts against the core via a limiting pin. At this time, the two axial end faces of the bellows are abutted. The square bodies at both ends of the connecting rod are installed and fitted onto the square grooves of the two support blocks. When the core is pulled out, the support ring expands outwards into the corresponding mounting groove inside the bellows. This achieves the goal of pre-aligning the support ring with the mounting groove inside the bellows after it retracts into the annular groove of the core. When the core is pulled out, multiple support rings expand outwards together and are installed into the mounting groove inside the bellows, solving the problem of low installation efficiency caused by obstructed vision when multiple support rings are inserted into the bellows by hand.

[0026] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0027] like Figures 1 to 4 As shown.

[0028] This application discloses a bellows support ring installation fixture, comprising:

[0029] The base plate 9 provides a load-bearing foundation for the whole. The base plate 9 has multiple mounting through holes for fixing. Support blocks 7 are fixedly installed on the base plate 9. The support blocks 7 are distributed at two intervals at both ends of the base plate 9. The support blocks 7 have square grooves for fitting and cooperating with the square bodies at both ends of the connecting rod 10 to prevent rotation.

[0030] The connecting rod 10, which has square ends, is mounted on the square groove of the support block 7 through the square ends.

[0031] The core 3 has a through hole in the middle. One end face of the core 3 has an annular limiting step to block one end of the bellows 21. The core 3 has an annular groove 6 on the outside. The annular groove 6 is a plurality of grooves spaced apart on the outer periphery of the core 3. The core is formed by the cooperation of the lower lobe core and the upper lobe core. The lower lobe core and the upper lobe core are limited and installed by the limiting rod 4. The lower lobe core and the upper lobe core are fixed and wrapped on the connecting rod 10 by screws 5, so that the core 3 is fixed and wrapped on the connecting rod 10 by screws 5.

[0032] The connecting rod 10 is fitted with an annular stop block 2. The stop block 2 has a through hole in the middle and is fitted onto the connecting rod 10. The stop block 2 abuts against the other axial end face of the core 3 through the limiting pin 1, so that the two axial end faces of the stop block 2 are respectively abutted by the limiting pin 1 and the core 3. When in use, the stop block 2 blocks the other end of the bellows 21.

[0033] The core 3 has a core 8 passing through it, and the core 3 is provided with a blocking through hole for the core 8 to pass through. The through hole is located on the core 3 at the outer radial position of the annular groove 6, so that after the core 8 passes through the blocking through hole, it can limit the inwardly retracted support ring 22 in multiple annular grooves 6.

[0034] It also includes a sleeve 11 with a sliding through hole inside, which can be slidably installed outside the core 3. The sleeve 11 is slidably fitted outside the core 3. When the support ring 22 is manually retracted into the annular groove 6, the manual can release the hand when the sleeve 11 is slidably fitted outside the core 3 and presses the support ring 22 inward. The core 8 is inserted into the through hole at the opening of the support ring 22 to prevent the support ring 22 from expanding outward.

[0035] In use, the core 3 is fixed to the connecting rod 10 by screws 5, and the sleeve 11 is slidably fitted on the end of the core 3 without the annular groove 6. The support ring 22 is manually retracted into the annular groove 6. The sleeve 11 slides outside the core 3, pressing the support ring 22 inward to release the hand. The core 8 passes through the blocking through hole of the core 3 and enters the through hole at the opening of the support ring 22 to prevent the support ring 22 from expanding outward. The process of retracting the support ring 22 into the annular groove 6 and the sleeve 11 sliding outside the core 3 to prevent the support ring 22 from expanding outward is repeated. When the support ring 22 is fully embedded in the annular groove 6 of the core 3, the sleeve 11 is detached from the outside of the core 3.

[0036] The corrugated pipe 21 is fitted onto the outside of the core 3, and the stop block 2 is held against the core 3 by the limiting pin 1. At this time, the two axial end faces of the corrugated pipe 21 are held against, and the two square bodies at both ends of the connecting rod 10 are installed and fitted on the square grooves of the two support blocks 7. When the core 8 is pulled out, the support ring 22 expands outward into the corresponding installation groove in the corrugated pipe 21. Since the support ring 22 is pre-corresponding to the installation groove in the corrugated pipe 21 after it is retracted in the annular groove 6 of the core 3, when the core 8 is pulled out, multiple support rings 22 expand outward together and are installed into the installation groove in the corrugated pipe 21. This solves the problem of low installation efficiency caused by the obstructed view when multiple support rings are inserted into the corrugated pipe by hand.

[0037] After the support ring 22 is installed inside the bellows 21, the openings of the support ring 22 are in contact with each other at 180°. Remove the stop block 2 and take out the bellows 21 with the support ring 22 installed.
