DETAILED DESCRIPTION

[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. The specific structures and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments set forth herein.

[0037] like Figures 1 to 4 As shown, according to an embodiment of the present disclosure, a toothed plate bevel milling and positioning device 100 is proposed, comprising: a conveying portion 110, used for conveying the toothed plate 200 along the length direction of the toothed plate 200; a positioning portion 120, used for positioning the first side or the second side of the toothed plate 200, wherein the first side and the second side are two opposite sides along the length direction of the toothed plate 200, and the first side is provided with teeth; an adjusting portion 130, used for adjusting the distance of the positioning portion 120 relative to the toothed plate 200; a milling machine 140, used for being arranged relative to the positioning portion 120 along the length direction of the toothed plate 200, wherein when the positioning portion 120 positions the first side, the milling machine 140 cuts the bevel of the second side; when the positioning portion 120 positions the second side, the milling machine 140 cuts the bevel of the first side.

[0038] It can be understood that the toothed plate beveling edge milling positioning device 100 provided in the embodiment of the present disclosure is provided with a conveying part 110, a positioning part 120, an adjusting part 130 and an edge milling machine 140. Among them, the conveying part 110 can convey the toothed plate 200 along the length direction of the toothed plate 200, and the speed of the conveying part 110 conveying the toothed plate 200 matches the speed of the milling cutter power head of the edge milling machine 140. The toothed plate 200 is formed with a first side and a second side in the length direction, the first side and the second side are arranged oppositely, and the first side is provided with a tooth shape. The edge milling machine 140 and the positioning part 120 are respectively arranged on both sides of the length direction of the toothed plate 200. When the positioning part 120 positions the first side, the edge milling machine 140 cuts the bevel of the second side; when the positioning part 120 positions the second side, the edge milling machine 140 cuts the bevel of the first side. In this way, the position of the toothed plate 200 is limited by the positioning part 120 and the position of the positioning part 120 relative to the toothed plate 200 can be adjusted by the adjusting part 130, so that the positioning part 120 positions the toothed plate 200 with appropriate pressure, thereby ensuring the positioning accuracy of the positioning part 120 to the toothed plate 200, and further ensuring the linear motion of the toothed plate 200, thereby avoiding the milling cutter power head from generating thrust on the toothed plate 200 during the milling process, causing lateral deviation of the toothed plate 200, resulting in problems such as lack of meat on the toothed plate 200, and improving stability, processing accuracy and processing efficiency.

[0039] It is understandable that in the related art, when a flame cutting machine is used for cutting, the toothed plate 200 is affected by the high temperature of the flame, and is bent and deformed due to the heat, and the local surface roughness of the toothed plate 200 does not meet the quality requirements, and a serrated shape is generated. The toothed plate bevel milling and positioning device 100 provided by the embodiment of the present disclosure can ensure the straightness of the toothed plate 200, and improve the processing accuracy of the toothed plate 200, and the appearance is beautiful, and the processing quality can meet the technical quality requirements, and no subsequent grinding is required, which saves processing time and improves processing efficiency. Specifically, when a flame cutting machine is used to cut the double-side bevel of the toothed plate 200, each operator produces 6 pieces per day, and when the toothed plate bevel milling and positioning device 100 provided by the embodiment of the present disclosure is used to cut the double-side bevel of the toothed plate 200, each operator produces 74 pieces per day, and the efficiency is increased by 12 times.

[0040] It should be noted that when processing the toothed plate 200, the toothed plate 200 is clamped by the conveying part 110 to move, which can limit the vertical freedom of the toothed plate 200; the milling machine 140 and the positioning part 120 cooperate to limit the horizontal freedom of the toothed plate 200, thereby avoiding the toothed plate 200 from being offset during the processing, ensuring the linear motion of the toothed plate 200 and the straightness after processing.

[0041] In some examples, the overall straightness of the positioning portion 120 is less than or equal to 0.5 mm; the adjustment portion 130 adjusts the moving distance of the positioning portion 120 to be in a range of 100 mm to 600 mm.

[0042] It is understandable that the overall straightness of the positioning part 120 is less than or equal to 0.5 mm, thereby ensuring that the toothed plate 200 can move in a straight line and ensure the processing straightness of the toothed plate 200. In addition, the adjustment part 130 can adjust the movement range of the positioning part 120 to 100 mm to 600 mm to adapt to toothed plates 200 of different sizes, thereby improving the applicability of the toothed plate beveling milling positioning device 100.

[0043] In some examples, such as Figures 1 to 3 As shown, the positioning portion 120 includes: a positioning rod 121; rollers 122, which are arranged at intervals on a side of the positioning rod 121 facing the edge milling machine 140 and are used for rolling connection with the toothed plate 200.

[0044] It is understandable that the positioning part 120 is provided with a positioning rod 121 and a roller 122. Among them, the positioning rod 121 is connected to the adjustment part 130, and a plurality of rollers 122 are provided, and the plurality of rollers 122 are arranged at equal intervals along the length direction of the positioning rod 121 on the side of the positioning rod 121 facing the edge milling machine 140. In this arrangement, the adjustment part 130 adjusts the position of the positioning rod 121 according to the size of the toothed plate 200, so that the roller 122 presses the toothed plate 200 with a suitable pressure, and when the conveying part 110 drives the toothed plate 200 to move, the toothed plate 200 is guided to move by the roller 122, and at the same time, the roller 122 can reduce the friction force on the toothed plate 200, and ensure the smoothness of the movement of the toothed plate 200 while ensuring the linear motion of the toothed plate 200.

[0045] Exemplarily, the length of the positioning rod 121 can be selected to be 1.8 m, and the spacing between the rollers 122 can be selected to be 200 mm.

[0046] In some examples, the straightness error of the center line connecting the plurality of rollers 122 is less than 0.3 mm / 1800 m.

[0047] It is understandable that the straightness error of the center line connecting the multiple rollers 122 is less than 0.3mm / 1800m, so as to ensure that the multiple rollers 122 can press the toothed plate 200 at the same time, so that the rollers 122 restrict the toothed plate 200 to make linear motion, so as to ensure the processing straightness of the toothed plate 200.

[0048] In some examples, such as Figures 1 to 3As shown, the positioning rod 121 includes: two first slats 1211 and the second slats 1212, the two first slats 1211 and the second slats 1212 are welded to form a groove structure, wherein the two first slats 1211 serve as a panel and a bottom plate respectively, and the second slats 1212 serve as a web; mounting grooves 1213 are opened at corresponding positions of the panel and the bottom plate, and the roller 122 is rotatably connected to the mounting groove 1213.

[0049] It is understandable that the positioning rod 121 is provided with two first slats 1211 and one second slat 1212. The first slat 1211 and the second slat 1212 can be welded into a groove structure by welding. Specifically, one of the first slats 1211 is used as a panel, the other first slat 1211 is used as a bottom plate, and the second slat 1212 is used as a web plate, and intermittent welding is adopted, and the weld feet are all 4mm. A plurality of mounting grooves 1213 are provided at intervals at corresponding positions on one side of the panel and the bottom plate facing the edge milling machine 140. The mounting grooves 1213 can be U-shaped grooves, and the number of the mounting grooves 1213 corresponds to the number of the rollers 122. The rollers 122 are installed in the mounting grooves 1213 and tightened and fixed by bolts. By adjusting the position of the rollers 122 in the mounting grooves 1213, the straightness error of the center connecting line of the plurality of rollers 122 is made less than 0.3mm / 1800m, and finally the bolts are spot welded to keep the position of the rollers 122.

[0050] In some examples, the parallelism between the panel and the base plate is less than 2 mm / m; the straightness errors of the mounting groove 1213 at the panel and the mounting groove 1213 at the base plate are both less than 1 mm / m.

[0051] It can be understood that the parallelism of the panel and the base plate is less than 2mm / m, and the straightness errors of the mounting grooves 1213 at the panel and 1213 at the base plate are both less than 1mm / m, so as to ensure the installation reliability of the multiple rollers 122 and ensure that the straightness error of the center line of the multiple rollers 122 is less than 0.3mm / 1800m.

[0052] In some examples, such as Figures 1 to 4 As shown, the adjusting part 130 includes: a connecting member 131 connected to the positioning rod 121 via a positioning pin 1311 ; and a hydraulic cylinder 132 , wherein the positioning rod 121 is connected to the hydraulic cylinder 132 via the connecting member 131 .

[0053] It is understandable that the adjustment part 130 may be provided with a connecting member 131 and a hydraulic cylinder 132. The connecting member 131 is provided with a positioning pin hole, and the positioning rod 121 is provided with mounting holes at intervals, and the positioning pin shaft 1311 is passed through the positioning pin hole and the mounting hole, so that the positioning rod 121 is connected to the connecting member 131 through the positioning pin shaft 1311. Further, the positioning rod 121 is connected to the hydraulic cylinder 132 through the connecting member 131. The positioning rod 121 is driven to move by the hydraulic cylinder 132.

[0054] For example, the rod length of the hydraulic cylinder 132 can be set according to the maximum rolling width of the rolling machine, for example, 500 mm, the width of the toothed plate 200 can be selected in the range of 200 mm to 500 mm, and the positioning part 120 can be telescopically positioned in the range of 100 mm to 600 mm by the hydraulic cylinder 132. The hydraulic cylinder 132 drives the positioning part 120 to push the toothed plate 200 with a thrust of 80 KN, and a pushing speed of 3 m / min.

[0055] In some examples, such as Figure 1 As shown, two hydraulic cylinders 132 are provided, which are spaced apart on the side of the positioning rod 121 away from the edge milling machine 140 through the connecting member 131 .

[0056] It is understandable that two hydraulic cylinders 132 can be provided, and the two hydraulic cylinders 132 are arranged at intervals on the side of the positioning rod 121 away from the milling machine 140 through the connecting piece 131, so that the thrust applied by the two hydraulic cylinders 132 to the positioning rod 121 is balanced and the straightness of the positioning rod 121 is improved.

[0057] For example, the distance between the two hydraulic cylinders 132 may be 1.1 m, and the two hydraulic cylinders 132 drive the positioning part 120 to exert a thrust force of 80 KN on the toothed plate 200 .

[0058] In some examples, the straightness error of the positioning pin hole of the connecting member 131 is less than 0.5 mm / 1800 mm.

[0059] It can be understood that the straightness error of the positioning pin hole of the connecting member 131 is less than 0.5mm / 1800mm, so as to ensure that when the hydraulic cylinder 132 pushes the positioning part 120, the straightness of the positioning part 120 meets the design requirements, thereby ensuring the positioning effect of the positioning part 120 on the toothed plate 200, ensuring that the conveying part 110 drives the toothed plate 200 to move in a straight line, and the processing straightness of the toothed plate 200.

[0060] In some examples, such as Figure 1 and Figure 2 As shown, the conveying part 110 is a roller press for clamping and conveying the toothed plate 200 .

[0061] It is understandable that the conveying part 110 can use a rolling machine, and the clamping rollers of the rolling machine can clamp the toothed plate 200 to move, so as to limit the vertical freedom of the toothed plate 200, reduce the shaking of the toothed plate 200, and improve the movement stability of the toothed plate 200.
