Description

Technical Field

[0001] The present invention relates to an insulating pull rod core mold for winding polyester cloth and fiber cloth in the field of the power industry, and particularly to an automatic assembly device and method for an insulating pull rod core mold. Background Art

[0002] At present, the production method of the insulating pull rod core mold for winding polyester cloth and fiber cloth in the power industry is that the core mold blank is manually wound completely, and then the core mold is manually pushed into the outer mold cavity. During the process of manually pushing the core mold, the wrinkled cloth needs to be smoothed little by little with hands continuously. The cloth is smoothly attached to the core mold. Every time a section of the core mold is pushed into the outer mold cavity, the cloth needs to be smoothed manually once until the entire core mold completely enters the outer mold cavity. During the assembly process, the skill levels of each person are uneven, and the quality of the products cannot be stable during mass production. The quality of the produced products has relatively high requirements for the personal operation skills of the producers.

[0003] When performing manual operations, when the core mold is pushed into the outer mold, the cloth on the outer layer of the core mold will form wrinkles. When the wrinkles accumulate to a certain extent, the core mold cannot be loaded into the outer mold. At the same time, the generation of wrinkles will also cause the product quality to be unqualified. Therefore, during the process of loading the core mold, the outer layer cloth needs to be continuously smoothed to facilitate the core mold to enter the outer mold cavity. This operation process has relatively high requirements for personal skills. The skill level of the operator directly affects the product quality. Moreover, during manual operation, the physical consumption is large, and the output cannot be increased quickly. Currently, there is no relevant automated equipment in the industry that can perform the assembly of the core mold.

[0004] Taking "insulating pull rod and smoothing" as the abstract keywords and the retrieval time point as November 2023, a search was conducted in the Chinese Patent Publication Database, and no relevant literature was found. Summary of the Invention

[0014] A concentric guide hole 39 is arranged in the middle of the rotating gear 37; two sets of arc-shaped inner walls 13 capable of concentric clamping are arranged on the disk surface of the rotating gear 37;

[0015] The centers of the two groups of concentrically clamped arc-shaped inner walls 13 are concentric with the concentric guide holes 39 .

[0016] A further technical solution of the present invention is that an optical axis guide rod 16 is arranged below the V-groove tooling 14 , and the optical axis guide rod 16 passes through a light hole on a supporting beam 18 , and the supporting beam 18 is located below the V-groove tooling 14 .

[0017] A further technical solution of the present invention is that the mechanism driving gear 32 can be driven by the module driving servo motor 24 , and the module driving servo motor 24 is mounted on the motor fixing plate 27 .

[0018] A further technical solution of the present invention is that an idler wheel fixed bearing 33 and an idler wheel rotating shaft 34 are arranged on a vertical plate arranged on a slider on the track of the linear module 25 .

[0019] A further technical solution of the present invention is that a block where one of the two groups of concentrically clamped arcuate inner walls 13 is located can be driven by the cloth-pulling and clamping cylinder 30 to allow the two cloth-pulling and clamping cylinders to clamp or move away.

[0020] A further technical solution of the present invention is that the core pushing mechanism structure is as follows: a horizontally arranged rack 9 is arranged on the pushing frame 40, the rack 9 can mesh with the gear driven by the worm gear reducer 11, the worm gear reducer 11 and the motor are installed on a board, and when the motor is started, the board can move left and right along the rack 9, and a core mold push rod bracket 12 is fixedly connected to the board, and when the core mold push rod bracket 12 moves, it can push the core mold 4 with the polyester cloth and the fiber cloth rolled up from the V-groove tooling 14.

[0021] A further technical solution of the present invention is that it further includes a core mold rotation and pressing mechanism 20. The core mold rotation and pressing mechanism 20 is provided with a cylinder fixing plate 22. A rotation and pressing cylinder 21 is arranged on the cylinder fixing plate 22. At the end of the cylinder shaft of the rotation and pressing cylinder 21, there is a pressure head fixing plate 20. A pressure head 19 is arranged at the end of the pressure head fixing plate 20.

[0022] A method for automatic assembly of an insulating pull rod core mold, characterized in that it uses the automatic assembly equipment for an insulating pull rod core mold described in any one of the above, and includes the following steps:

[0023] When the equipment is working, the core mold 4 wrapped with polyester cloth and fiber cloth is placed into the V-shaped groove tooling 14 in the lifting mechanism 1. The lifting cylinder 15 lifts the V-shaped tooling support plate 17, places the core mold 4 wrapped with polyester cloth and fiber cloth into the V-shaped groove tooling 14, and the lifting cylinder 15 retracts to the original position, aligning the core mold 4 wrapped with polyester cloth and fiber cloth and the inner hole of the insulating pull rod outer mold 7 on the same axis for preparation of assembly;

[0024] Then, the three-phase asynchronous motor 10 in the core mold push rod mechanism 6 rotates. The motor drives the worm and worm gear reducer 11 to rotate and simultaneously drives the gear. The gear rotates on the rack 9, driving the mechanism to move. The core mold push rod support 12 drives the core mold push rod 8 to move forward, pushing the core mold 4 wrapped with polyester cloth and fiber cloth forward and inserting it into the insulating pull rod outer mold 7.

[0025] During the process of inserting the core mold 4 wrapped with polyester cloth and fiber cloth into the insulating pull rod outer mold 7, first, the head of the core mold enters the hole of the insulating pull rod outer mold 7, and then the rotation and pressing cylinder 21 in the core mold rotation and pressing mechanism 2 acts, driving the pressure head fixing plate 20 and the pressure head 19 to press on the nylon cloth on the outer layer of the core mold;

[0026] After being fixed, the core mold cloth-straightening mechanism 3 operates. The cloth-straightening clamping cylinder 30 drives the cloth-straightening tooling 31 to clamp the core mold. After clamping, the driving wheel drives the servo motor 26 to rotate, which drives the mechanism driving gear 32 to rotate. The mechanism driving gear 32 transmits the power to the rotating large gear 37 through the idler gear 28. The rotation of the rotating large gear 37 drives the cloth-straightening clamping cylinder 15 to rotate, and then drives the cloth-straightening tooling 31 to rotate to straighten the nylon cloth on the core mold through spiral rotation. At this time, the nylon cloth on the core mold is located between the two arc-shaped inner walls 13. While the rotating large gear 37 is rotating, the module driving servo motor 24 rotates, driving the linear module 25. The linear module 25 drives the entire mechanism to move backward, achieving axial movement while rotating, in two actions. The first time the filter cloth is clamped by a 0.3Mpa cylinder. After completion, the pressing head at the rear end presses. At this time, after a 1-second delay, the clamping cylinder switches to 0.6Mpa air pressure and repeats the cloth-filtering action in the reverse direction, and the pressing head at the start is released. The purpose of switching the air pressure is to push the first-pass filtered cloth section into the outer mold hole through the combined action of reverse cloth rotation + rear-end propulsion force. After completion, repeat the above actions until the entire core mold is pushed into the outer mold hole to straighten the nylon cloth outside the core mold;

[0027] After completing the above actions, the rotating clamping cylinder 15 in the core mold rotating and clamping mechanism 2 operates and no longer presses down on the core mold. Then, the assembled core mold push rod mechanism 6 pushes the core mold into the hole of the insulating pull rod outer mold 7 again. Repeat the above actions, straightening the polyester cloth outside the core mold while pushing the core mold until the entire core mold is pushed into the insulating pull rod outer mold 7; According to the above actions, the equipment can realize the automatic loading of the core mold 4 with rolled polyester cloth and fiber cloth into the mold and continuously straighten the cloth during the loading process.

The lifting cylinder (15) jacks up the V-shaped tooling support plate (17), places the core mold (4) wrapped with polyester cloth and fiber cloth into the V-shaped groove tooling (14), the lifting cylinder (15) retracts to its original position, so that the core mold (4) wrapped with polyester cloth and fiber cloth and the inner hole of the insulating pull rod outer mold (7) are on the same axis, and preparation for assembly is made; Then, the three-phase asynchronous motor (10) in the core mold push rod mechanism (6) rotates. The motor drives the worm and gear reducer (11) to rotate and simultaneously drives the gear. The gear rotates on the rack (9), driving the mechanism to move. The core mold push rod bracket (12) drives the core mold push rod (8) to move forward, pushing the core mold (4) wrapped with polyester cloth and fiber cloth forward and loading it into the insulating pull rod outer mold (7). During the process of loading the core mold (4) wrapped with polyester cloth and fiber cloth into the insulating pull rod outer mold (7), first, the head of the core mold enters the hole of the insulating pull rod outer mold (7). Then, the rotary pressing cylinder (21) in the core mold rotary pressing mechanism (2) acts, driving the pressure head fixing plate (20) and the pressure head (19) to press on the nylon cloth on the outer layer of the core mold; After fixing, the core mold cloth-straightening mechanism (3) acts. The cloth-straightening clamping cylinder (30) drives the cloth-straightening tooling (31) to clamp the core mold. After clamping, the driving wheel drives the servo motor (26) to rotate, driving the mechanism driving gear (32) to rotate. The mechanism driving gear (32) transmits the power through the idler gear (28) to the large rotating gear (37). The large rotating gear (37) rotates, driving the cloth-straightening clamping cylinder (15) to rotate, and then driving the cloth-straightening tooling (31) to rotate to straighten the nylon cloth on the core mold through spiral rotation. At this time, the nylon cloth on the core mold is located between two arc-shaped inner walls (13). While the large rotating gear (37) rotates, the module driving servo motor (24) rotates, driving the linear module (25). The linear module (25) drives the entire mechanism to move backward, achieving axial movement while rotating, in two actions. For the first time of cloth filtering, it is clamped with a 0.3Mpa cylinder. After completion, the rear-end pressing head presses. At this time, after a 1-second delay, the clamping cylinder switches to 0.6Mpa air pressure and repeats the cloth filtering action in the opposite direction, and the pressing head at the start is loosened. The purpose of switching the air pressure is to push the cloth section filtered for the first time into the outer mold hole through the reverse rotation of the cloth filtering + the rear-end pushing force. After completion, repeat the above actions until the entire core mold is pushed into the outer mold hole to straighten the nylon cloth outside the core mold; After completing the above actions, the rotary pressing cylinder (15) in the core mold rotary pressing mechanism (2) operates, no longer pressing down the core mold. Then, the assembled core mold push rod mechanism (6) pushes the core mold into the hole of the insulating pull rod outer mold (7) again for a certain distance. Repeat the above actions, while smoothing the polyester cloth outside the core mold and pushing the core mold until the entire core mold is pushed into the insulating pull rod outer mold (7); according to the above actions, the equipment can realize the automatic loading of the core mold (4) with the polyester cloth and fiber cloth wound well in the industry into the mold and continuously smooth the cloth during the loading process.
