DETAILED DESCRIPTION
[0020] In order to make the technical solution and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
[0021] like Figure 1 As shown, a coaxial tube automatic bending device includes a frame body 1, an automatic feeding mechanism 2 and a loading mechanism 3 fixed on the frame, an outer tube rotating mechanism 4 and a tube bending machine 5. The tube bending machine 5 is used to perform tube bending operations on linear coaxial tubes. At the same time, the loading mechanism 3 is located on the top of the automatic feeding mechanism 2, and is used to feed the linear coaxial tube into the outer tube rotating mechanism 4, and then the linear coaxial tube is automatically bent by the tube bending machine 5.
[0022] like Figure 1 , Figure 4 , Figure 5 As shown, the automatic feeding mechanism 2 includes two supporting tooth plates 21 fixed on the frame body 1 and two driving tooth plates 22 for matching with the corresponding supporting tooth plates 21 and driving the coaxial tube to move from one end to the other end of the supporting tooth plates 21. Among them, the top of the supporting tooth plate 21 is tooth-shaped and is used to support the two ends of the coaxial tube respectively, and the top of the driving tooth plate 22 is tooth-shaped and is used to lift the coaxial tube to move toward one end of the supporting tooth plate 21 close to the feeding mechanism 3.
[0023] It should be noted that a feeding motor 23 and two feeding rollers 26 which are parallel to each other and penetrate the supporting gear plate 21 and the driving gear plate 22 are fixed on the frame body 1. A motor rotating gear 231 which is rotatably connected to the frame body 1 is provided at one end of the feeding roller 26, and a synchronous belt 25 is provided between the two motor rotating gears 231 to achieve the purpose of synchronous driving. Among them, the bearing axis in the supporting gear plate 21 coincides with the feeding roller 26, and a cam 221 is provided in the driving gear plate 22, and the feeding roller 26 penetrates the cam 221 and is connected, and the axes are separated from each other, so that when the feeding roller 26 performs circumferential rotational motion, the cam 221 performs circumferential rotational motion with the feeding roller 26 as the axis, and plays the role of transmitting the coaxial tube to the upper feeding mechanism 3.
[0024] At the same time, a plug-in fixing unit 24 is provided on the frame body 1. The plug-in fixing unit 24 is composed of two plug-in connectors that are close to or far away from each other, and the plug-in connector is used to be inserted into the inner side of the corresponding end of the coaxial tube and to be clamped by the feeding mechanism 3. Therefore, when the coaxial tube is transferred to one end of the plug-in fixing unit 24 by the driving tooth plate 22, as the driving tooth plate 22 lifts the coaxial tube to the upper side of one end of the plug-in fixing unit 24, the driving plug-in connector is inserted into the two ends of the coaxial tube, so that the coaxial tube and the supporting tooth plate 21 can be classified, so as to facilitate the feeding mechanism 3 to grab.

Therefore, under the three-axis linkage drive of the longitudinal motor 37, the transverse motor 31 and the lifting motor 322, the mechanical gripper 36 will be effectively adjusted, so that the mechanical gripper 36 has the effect of efficiently and stably grasping the coaxial tube.
[0026] like Figure 1 , Figure 3 As shown, the outer tube rotating mechanism 4 includes a fixed base plate 41 fixed on the tube bending machine 5. A transverse rail 411 is arranged on the upper side of the fixed base plate 41, and the transverse rail 411 is slidably connected to the transverse plate 42. At the same time, a longitudinal rail 421 is arranged on the upper side of the transverse plate 42, and the longitudinal rail 421 is slidably connected to the rotating seat 43. The rotating seat 43 is provided with rotating clamping teeth 443 for clamping the coaxial tube. It should be mentioned that a transverse motor 412 is arranged at the bottom of the fixed base plate 41. The output end of the transverse motor 412 passes through the upper end of the fixed base plate 41 and is connected to a rotating gear 413, and a longitudinal straight tooth 423 meshing with the rotating gear 413 is arranged at the bottom of the transverse plate 42, and a telescopic cylinder 422 connected to the rotating seat 43 is arranged at one end of the transverse plate 42. Therefore, the horizontal displacement of the rotating seat 43 is effectively driven by the telescopic cylinder 422 and the transverse motor 412, so that the coaxial tube can be automatically loaded and unloaded and the hole can be automatically determined to realize an unmanned automatic production mode.
[0027] It should be mentioned that a rotating motor 44 is provided on the rotating seat 43. The rotating motor 44 is used to drive the rotating clamping teeth 443 to rotate concentrically, and the rotating clamping teeth 443 are provided with an opening groove 4431. Among them, a large gear 441 is provided at the output end of the rotating motor 44. At least two meshing pinions 442 are meshed on the outer side of the large gear 441, and the two meshing pinions 442 are meshed with the rotating clamping teeth 443, so that the two meshing pinions 442 effectively drive the rotating clamping teeth 443 to rotate, and realize the effect of effectively positioning the coaxial tube in the rotating clamping teeth 443 and reducing the difficulty of the automatic tube bending operation.
[0028] In summary, the present application provides a coaxial tube automatic bending device, which transmits the linear coaxial tubes one by one to one end close to the feeding mechanism 3 through the automatic feeding mechanism 2, and then grabs and transmits them to the outer tube rotating mechanism 4 through the feeding mechanism 3, so that the outer tube rotating mechanism 4 cooperates with the tube bending machine 5 to achieve the effect of automatic tube bending operation, so that the coaxial tube automatic bending device can achieve the purpose of improving product processing efficiency and yield; at the same time, the automatic feeding mechanism 2 adopts the feeding motor 23 to drive the cam 221 to rotate, thereby driving The coaxial tube moves along the toothed top of the supporting tooth plate 21 to achieve the purpose of improving the feeding stability and feeding speed of the coaxial tube; the feeding mechanism 3 is coordinated by the lifting motor 322, the longitudinal movement motor 37 and the transverse movement motor 31 to realize three-axis linkage, thereby improving the operation convenience of the coaxial tube automatic bending equipment; the outer tube rotating device is controlled by the rotating motor 44 to control the rotation of the large gear 441, so that the rotation is transmitted to the rotating clamping tooth 443 through the meshing small gear 442, so that the rotating clamping tooth 443 with the open groove 4431 plays a role of convenient transmission.
