Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0034] Please refer to Figures 1 to 6 The present invention illustrates a specific embodiment of a fork tool for removing excess insulator material.

[0035] A fork tool for removing excess material from an insulator 2 includes: a base 3, a positioning mechanism 4 arranged on the base 3, a clamping mechanism 5, and a fork mechanism; the positioning mechanism 4, arranged on the base 3, is used to fix and shape the end of the insulator 2; the positioning mechanism 4 includes: a positioning block 41, fixed on the base 3, and having a through-hole for the end of the insulator 2 to be movably inserted; a positioning rod 42, fixed in the through-hole and arranged parallel to the length of the insulator 2, to cooperate with the positioning block 41 to limit the inner and outer sides of the insulator 2 inserted into the through-hole, and the end of the positioning rod 42 facing away from the fork body 1 extends out of the through-hole to cooperate with the clamping mechanism 5 to limit the inner and outer sides of the insulator 2 outside the through-hole. The end of the positioning rod 42 facing away from the fork body 1 is a conical head, which facilitates insertion into the interior of the insulator 2.

[0036] The clamping mechanism 5 is arranged at the rear end of the positioning mechanism 4, and is used for clamping the insulator 2 outside the positioning mechanism 4 to limit the movement of the end of the insulator 2. The clamping mechanism 5 comprises a first clamping unit 51 and a second clamping unit 52 arranged oppositely at both sides of the rear end of the positioning mechanism 4. Both the first clamping unit 51 and the second clamping unit 52 comprise a push cylinder and a chuck fixed to the movable end of the push cylinder. The two chucks oppositely clamp the two side walls of the insulator 2 under the drive of the push cylinder, and cooperate with the positioning rod 42 to fix the insulator 2.

[0037] The fork knife mechanism is arranged at the front end of the positioning mechanism 4, and is used for cutting the reinforcing rib 21 inside the insulator 2 at the guiding and positioning position. The fork knife mechanism comprises a fork knife body 1 arranged in parallel along the length direction of the insulator 2. An arc-shaped notch 10 is formed in the front part of the fork knife body 1, and a knife edge 11 is formed at both sides. An arc-shaped part 110 is cut in the center of the knife edge 11. A guide groove 12 is formed in the inside wall of the fork knife body 1 from the arc-shaped part 110 to the bottom of the arc-shaped notch 10, and is used for guiding the reinforcing rib 21 to be cut to smoothly turn at the bottom of the arc-shaped notch 10, so as to avoid the reinforcing rib 21 sliding out of the arc-shaped notch 10 in the cutting process, affecting the reinforcing rib 21 at the knife edge, and making it unable to break. The guide groove 12 can be an arc-shaped groove. The end of the guide groove 12 is provided with a slope 13 which is smoothly connected with the bottom arc surface of the arc-shaped notch 10. The slope 13 can effectively guide the end of the reinforcing rib 21 again and provide a turning angle for it. The reinforcing rib 21 is guided by the guide groove 12 and turns at the bottom of the arc-shaped notch 10 in the cutting process of the fork knife body 1, so that the reinforcing rib 21 at the knife edge 11 breaks. A T-shaped block 14 is formed at the rear end of the fork knife body 1, and is used for clamping by the clamp 6. The clamp 6 is used for clamping the rear part of the fork knife body 1, and is provided with a first driving unit 60 for driving the fork knife body 1 to cut the reinforcing rib 21 inside the insulator 2 from the end of the insulator 2. The first driving unit 60 adopts a driving cylinder.

[0038] The fork knife guide 7 is located at the side of the positioning mechanism 4 close to the fork knife body 1, and is used for limiting and guiding the stroke of the fork knife body 1. The fork knife guide is a plate-shaped structure, and is fixed to the side of the positioning block 41 away from the insulator 2. The fork knife guide is provided with a through hole which communicates with the special-shaped hole, and is used for partially penetrating the fork knife body 1 and forming a sliding limiting cooperation.

[0039] In the embodiment, the inside wall of the front end of the fork knife body 1 is a slope section which is smoothly connected with the bottom arc surface of the arc-shaped notch 10. There is an included angle θ between the outside wall of the knife edge 11 of the fork knife body 1 and the slope section. The included angle θ is in the range of 25-30°. In the embodiment, the included angle θ is 27°.

[0040] Working principle: one end of the insulator 2 is inserted into the special-shaped hole of the positioning block 41, the positioning rod 42 and the positioning block 41 jointly shape the insulator 2 inserted into the special-shaped hole, the positioning rod 42 extending out of the special-shaped hole cooperates with the clamping mechanism 5 to jointly clamp and shape the insulator 2 outside the special-shaped hole, the first driving unit 60 drives the clamp 6 to drive the fork knife body 1 to enter the inside of the insulator 2 along the linear trajectory through the through hole of the fork knife guide 7, at the same time, the knife edge end 11 of the fork knife body 1 strengthens the inside reinforcing rib 21 of the shaped section of the insulator 2, after cutting a distance, the cut part of the reinforcing rib 21 is guided to the bottom of the arc-shaped notch 10 along the guide groove 12 and turns, based on the brittleness of the reinforcing rib 21 excess material, finally, the reinforcing rib 21 at the knife edge end 11 will break, to complete the whole cutting process.

[0041] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be combined appropriately to form other embodiments that those skilled in the art can understand.
