[0002] Most modern cutting tools, such as broaches, gear cutters, taps, drills, milling cutters, etc., are still made of high-speed steel. In modern industrial products, more and more structural materials with high strength and good toughness are used. Due to the high hardness, serious work hardening phenomenon, poor thermal conductivity and other reasons of these materials, it is difficult for the high-speed steel tools currently used to cut these materials. Coated tools are considered a revolution in tools. Surface coating of tools is very effective in improving tool life. Coating not only improves the surface hardness of the tool and enhances its wear resistance, but also reduces the friction coefficient of the tool surface, increases lubrication ability, and improves product quality and production efficiency.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1-3The utility model provides an embodiment: a hanger for spray coating on the surface of a tool, comprising a plurality of frames 1, wherein the plurality of frames 1 are arranged in a straight line to form a long strip-shaped hanger frame 3, a worm 2 is rotatably connected to the top side of the frame 1, an external rod 9 is arranged on the rear side of the rearmost worm 2, a motor is externally connected to the rear end of the external rod 9, the rear end of the plurality of worms 2 at the rear end and the rearmost worm 2 and the external rod 9 are connected via a connecting assembly, the middle ends of the left and right sides of the frame 1 are fixedly connected to the frame 3, the top side of the frame 3 is rotatably connected to a worm wheel 4, the outer wall of the worm wheel 4 is meshed with the middle end of the outer wall of the worm 2, a rotating rod 5 is located on the bottom side of the worm wheel 4, the top end of the rotating rod 5 is fixedly connected to the bottom center of the worm wheel 4, and the bottom end of the rotating rod 5 is fixedly connected to a hook 6;

[0027] Specifically, the hanger can freely plan the overall length of the hanger through the modular design, so as to adapt to the production lines of various tool surface spraying, and can be split so that the hanger can be more convenient to store and transport when the spraying equipment is moved and transported, making the transportation of the spraying equipment matched with it more convenient and efficient. The external rod 9 is connected to the external power source motor, so that the external rod 9 can rotate and drive the worm 2 connected to it to rotate, the worm 2 thread drives the worm wheel 4 to rotate, and the worm wheel 4 drives the bottom side of the rotating rod 5 and the hook 6 with the tool hanging on it to rotate, so that the hook 6 and the tool mounted on it continuously change the angle to be sprayed and coated, making the spray coating work more comprehensive.

[0028] Reference Figure 2 - Figure 5 The fitting sleeve 7 fixedly connected to the rear side of the worm 2 is sleeved on the outer wall of the fitting member 8 fixedly connected to the front sides of the worm 2 and the external connecting rod 9; the bottom end of the connecting member 15 fixedly connected to the rear side of the frame 1 abuts against the top end of the supporting seat 16 fixedly connected to the front side of the frame 1;

[0029] Specifically, when multiple hanger modules are spliced, multiple worms 2 need to be connected, and the interlocking sleeve 7 is set on the outer wall of the interlocking member 8, so that two worms 2 are spliced ​​or the worm 2 at the rear end is connected to the external rod 9 as a power source. When the worm 2 rotates, the irregular interlocking sleeve 7 and the interlocking member 8 can be engaged with each other, thereby driving it to rotate. The shape of the support seat 16 matches that of the connecting member 15. Through the support of the support seat 16, the connecting member 15 can obtain a force support point, thereby providing a certain degree of support for the frame 1.

[0030] Reference Figure 2 , Figure 3 and Figure 6, the front end of the sliding sleeve 10 fixedly connected to the front ends of the left and right sides of the frame 1 is provided with a sliding member 11, the rear end of the sliding member 11 is slidably connected to the inside of the sliding sleeve 10, and the rear side of the sliding member 11 is provided with a spring 13, one end of the spring 13 is connected to the inside of the sliding sleeve 10, and the other end of the spring 13 is connected to the rear side of the sliding sleeve 10, the front end of the sliding member 11 is rotatably connected with a female buckle 12, and the rear ends of the left and right sides of the frame 1 are fixedly connected with a male buckle 14, and the inner part of the female buckle 12 is sleeved on the outer wall of the male buckle 14 and abuts against the outer wall of the male buckle 14;

[0031] Specifically, after a plurality of hanger modules are spliced, they will be fixed. By pulling the slide 11, the slide 11 drives the connected female buckle 12 to extend, and stretches the spring 13 in the slide sleeve 10. The extended female buckle 12 is mounted on the male buckle 14 by rotation. The stretched spring 13 will exert a pulling and resetting force on the slide 11 due to resetting, thereby tightening the female buckle 12 on the male buckle 14 and being locked and limited by the male buckle 14.

[0032] Working principle: When assembling the hanger, place the connecting parts 15 on the multiple frames 1 on the support seat 16, and put the fitting sleeve 7 on the outer wall of the fitting sleeve 8 to complete the splicing between the multiple worm gears 2 and the splicing between the worm gears 2 and the external rod 9, and then fix them. By pulling the slide 11, the slide 11 drives the female buckle 12 connected thereto to extend, and stretches the spring 13 in the slide sleeve 10. The extended female buckle 12 is rotated and put on the male buckle 14. The stretched spring 13 will apply a pulling and resetting force to the slide 11 due to the reset, so that the female buckle 12 is tightened on the male buckle 14, and is locked and limited by the male buckle 14 to complete the installation and splicing of the hanger. When the tool is being spray-coated, the worm 2 connected to it is driven to rotate by the external rod 9, and the irregular interlocking sleeves 7 and interlocking parts 8 of multiple worms 2 are engaged with each other, thereby driving the entire spliced ​​worm 2 to rotate, and the rotating worm 2 thread drives the worm wheel 4 to rotate, and then the worm wheel 4 drives the rotating rod 5 on the bottom side and the hook 6 with the tool hung on it to rotate, so that the hook 6 and the props mounted on it continuously change their angles to be spray-coated, making the spray coating work more comprehensive.
