[0025] like Figures 1 to 4 As shown, the present invention provides a screw processing milling device, including a base 1, a horizontal milling device is installed above the base 1 through a bracket, the milling device includes a milling tube 2 in the middle and a conveying tube 3 at both ends, a milling assembly for milling is arranged in the milling tube 2, the milling tube 2 is coaxially and transversely arranged with the conveying tubes 3 on both sides, and the milling tube 2 is rotatably connected to the conveying tubes 3 on both sides, and a conveying assembly for conveying a screw 4 that needs to be milled is arranged in the conveying tubes 3, and the conveying assembly includes at least three through grooves 5 opened on the inner side wall of the conveying tube 3, and a conveying chain plate 7 is installed in the through groove 5 through a group of conveying rollers 6. The outer side of the conveying chain plate 7 is installed with several conveying blocks 8 evenly distributed along its length direction. The outer side of the conveying block 8 is an arc with the concave surface facing outward. A tensioning adjustment component is provided between each group of conveying rollers 6 to keep the conveying chain plate 7 tight and make the conveying block 8 close to the axis of the conveying pipe 3 contact and cooperate with the screw 4 for conveying. In this way, the tensioning adjustment component can make the outer sides of all the conveying blocks 8 close to the inner side of the conveying pipe 3 contact and cooperate with the outer periphery of the screw 4 to be conveyed, thereby clamping and conveying the screw 4. Of course, a power drive component is provided in the conveying pipe 3 corresponding to each group of conveying rollers 6.

[0026] In this initial state, the conveying chain plate 7 on the side close to the axis of the conveying tube 3 is in a horizontal state through the tensioning and adjusting component, so that the screw 4 that needs to be milled is inserted into the conveying tube 3 from the left end of the conveying tube 3, and then the conveying blocks 8 on the side close to the screw 4 are clamped on the outside of the screw 4 through the tensioning and adjusting component, and then the screw 4 is rotated to the right through the conveying roller 6, so that the screw 4 is conveyed to the milling tube 2, and the screw 4 is milled by the milling component inside the milling tube 2, and the screw 4 is conveyed to the right under the transmission of the conveying component on the right.

[0027] like Figure 1As shown in the figure, metal debris will be generated during the rotary milling of the screw 4, and the overall noise is relatively large. In order to reduce the noise, preferably, a sleeve 9 is hingedly installed at the outer end of the conveying tube 3 through an electric hinge. The sleeve 9 is made of a retractable elastic bellows, and the outer end of the sleeve 9 is closed. The outer end of the right sleeve 9 is connected to the blowing assembly and communicates with it, and the outer end of the left sleeve 9 is connected to the suction assembly. The sleeve 9 rotates under the action of the electric hinge to cover the outer side of the conveying tube 3 on the corresponding side, and the end of the conveying tube 3 is sealed by the sleeve 9, so that the entire device is in an approximately sealed state. While reducing the noise, the metal debris generated in the rotary milling process is sucked out through the cooperation of the blowing assembly and the suction assembly.

[0028] like Figure 2 As shown in , one embodiment of the tension adjustment assembly is that a fixed block 10 is installed between each group of conveying rollers 6, and at least two first electric telescopic rods 11 are installed on the side of the fixed block 10 close to the inside of the conveying tube 3, and the free ends of the first electric telescopic rods 11 are all facing the axis of the conveying tube 3, and the free ends of the first electric telescopic rods 11 are installed with a first tensioning wheel 12, and at least two second electric telescopic rods 13 are installed on the side of the fixed block 10 away from the conveying tube 3, and the second electric telescopic rods 13 are evenly distributed along the length direction thereof. A second tensioning wheel 14 is installed on the outer end of each of the transmission tubes 3. In this way, through the telescopic cooperation of the first electric telescopic rod 11 and the second electric telescopic rod 13, when the first tensioning wheel 12 pushes the transmission chain plate 7 toward the inner side of the transmission tube 3, the transmission block 8 clamps the screw 4, and the second tensioning wheel 14 moves toward the side of the fixed block 10 under the contraction of the second electric telescopic rod 13, and the lower transmission chain plate 7 is also tightened, thereby maintaining the tensioned state of the transmission chain plate 7, and at the same time, the transmission block 8 is pushed and moved, so that the transmission block 8 clamps the screw 4.

[0029] like Figure 1 , 4As shown, in order to perform milling on the screw 4 during the transmission process, an implementation method of the milling assembly is that the milling tube 2 is installed on the top of the base 1 through a guide support assembly, and a plurality of first motors 15 uniformly distributed in an annular shape are fixedly installed on the inner wall of the middle part of the milling tube 2, and the output shafts of the first motors 15 are all facing the side of the axis of the milling tube 2, and the outer ends of the output shafts of the first motors 15 are fixedly installed with third electric telescopic rods 16, and the outer ends of the third electric telescopic rods 16 are fixedly installed with drill bits 17, and in order to keep the screw 4 moving stably during the milling process, a group of fourth electric telescopic rods 18 uniformly distributed in an annular shape with their active ends facing the side of the axis of the milling tube 2 are respectively installed on both sides of the first motor 15. Universal wheels 19 are installed at the movable ends of the telescopic rods 18, and a first power device for driving the milling tube 2 to rotate is provided on the outer side of the milling tube 2. In this way, the universal wheels 19 are moved vertically by the fourth electric telescopic rod 18, so that the outer periphery of the screw 4 is pushed and clamped by the universal wheels 19 on both sides of the first motor 15, and the screw 4 moves freely to the left under the action of the transmission assembly. The process of the universal wheels 19 keeping the screw 4 clamped does not affect the movement of the screw 4. At the same time, the first power assembly drives the milling tube 2 to rotate, so that the first motor 15 rotates to drive the drill bit 17 to mill the outer periphery of the moving screw 4, and multiple drill bits 17 can realize multiple sets of thread milling operations on the same screw 4.

[0030] More preferably, in order to provide stable support for the rotary milling tube 2, an embodiment of the guide support assembly is that guide rails 20 are mounted on the outer periphery of the two end portions of the rotary milling tube 2, and mounting seats 21 corresponding to the guide rails 20 are fixedly installed on the top surface of the base 1, and guide sliders 22 are installed on the upper ends of the mounting seats 21, and the guide sliders 22 are slidably matched with the corresponding guide rails 20. In this way, the rotary milling tube 2 is more stable during rotation through the sliding cooperation between the guide rails 20 and the guide sliders 22 and the support of the mounting seats 21.

[0031] like Figure 1 , 2 As shown, one implementation of the first power component is to fix a gear ring 23 on the outside of the milling tube 2, and to fix a driving motor 24 on the top surface of the base 1. A gear 24 is fixedly installed on the output shaft of the driving motor 24, and the gear 24 is meshed with the gear ring 23, so that the milling tube 2 is driven to rotate by the driving motor 24.

[0032] Working principle: in the initial state, the sleeve 9 at the left end covers the conveying tube 3 on the corresponding side, the first electric telescopic rod 11 and the second electric telescopic rod 13 are in a normal extension state, and the conveying chain plates 7 of the conveying tube 3 are in a horizontal state. At this time, the distance between the conveying blocks 8 located on the same conveying tube 3 near the middle of the conveying tube 3 is the largest, and the third electric telescopic rods 16 corresponding to all the drill bits 17 are in a retracted state, and the fourth electric telescopic rods 18 are also in a retracted state; then the screw 4 that needs to be milled is inserted into the conveying tube 3 on the right side, and the sleeve 9 on the right side covers the outer side of the conveying tube 3 on the corresponding side, and the first electric telescopic rod 11 and the second electric telescopic rod 13 in the left conveying tube 3 are extended and retracted, so that the conveying block 8 clamps the screw 4, and the conveying chain plates 7 located in the same conveying tube 3 move at the same speed and in the same direction, thereby The screw 4 is conveyed to the right. After the screw 4 is conveyed into the milling tube 2, the fourth electric telescopic rod 18 is extended to clamp the screw 4 and facilitate the movement of the screw 4. Then the driving motor 24 drives the milling tube 2 to rotate. At the same time, the third electric telescopic rod 16 is extended, and the first motor 15 drives the drill bit 17 to rotate, so that when the screw 4 moves to the left, the drill bit 17 rotates relative to the screw 4 and mills the outer periphery of the screw 4. At the same time, the blowing component and the suction component both work to suck out the metal debris generated during the milling process and reduce the noise generated during the milling process. The screw 4 continues to mill. When the screw 4 is longer, the screw 4 passes through the conveying tube 3 on the left, and the end of the screw 4 is inserted into the sleeve 9 on the left. Since the sleeve 9 is made of a corrugated elastic tube material, the insertion of the screw 4 into the sleeve 9 causes the sleeve 9 to extend, and will not affect the movement and milling of the screw 4.

[0033] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
