TECHNICAL FIELD

[0001] The utility model relates to the technical field of supporting wheel production, and specifically relates to an automatic supporting wheel production device. BACKGROUND

[0002] The supporting wheel is used to support the weight of the tractor and rolls on the guide rail (track chain link) or track plate surface, and is also used to limit the track and prevent lateral slipping. The supporting wheel is generally forged in a special mold, and after forging, medium-frequency quenching is used to improve the pressure load bearing performance of the supporting wheel.

[0003] Because the structure of the supporting wheel has a larger diameter at both ends and a smaller diameter at the middle part, when the supporting wheel is heated by medium frequency, the traditional heating method is to directly set the copper ring outside the supporting wheel. When the copper ring moves to the middle part of the supporting wheel, the distance between the copper ring and the surface of the supporting wheel will greatly increase. When the distance between the heated copper ring and the workpiece is too large, the LC oscillation current will be too large, which affects the service life of the equipment. SUMMARY

DETAILED DESCRIPTION

[0020] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0021] Referring to Figures 1-4 , an automatic supporting wheel production equipment includes a base 1 and a supporting wheel body 2.

[0022] The quenching mechanism comprises a vertical plate 3 fixedly connected to the upper end of the base 1, two air cylinders 4 fixedly connected to the side walls of the vertical plate 3, a middle-frequency heating plate 5 fixedly connected to the movable ends of the two air cylinders 4, and the outer side wall of the supporting wheel body 2 is attached to the side wall of the middle-frequency heating plate 5, so that the middle-frequency heating plate 5 can heat and quench the outer side wall of the supporting wheel body 2.

[0023] It should be noted that the middle-frequency heating plate 5 is a device that converts electrical energy into heat energy through electromagnetic induction principle, which is prior art and will not be described here.

[0024] The rotating mechanism comprises a cylinder 6 rotatably connected to the upper end of the base 1, an annular frame 7 fixedly connected to the upper end of the cylinder 6, a plurality of first plates 8 slidably connected to the inner wall of the annular frame 7, and arc-shaped plates 9 fixedly connected to the mutually distant side walls of the plurality of first plates 8, and the side walls of the arc-shaped plates 9 are attached to the inner side walls of the supporting wheel body 2.

[0025] The upper ends of the arc-shaped plates 9 are attached to the inner top portions below the supporting wheel body 2, so that when the upper ends of the plurality of arc-shaped plates 9 are attached to the inner top portions below the supporting wheel body 2, the outer side wall of the supporting wheel body 2 is attached to the side wall of the middle-frequency heating plate 5 (as shown in Figure 1 ).

[0026] The upper end of the cylinder 6 located in the annular frame 7 is fixedly connected with an electric push rod 10, the movable end of the electric push rod 10 is fixedly connected with a moving block 11, and the side walls of the moving block 11 are rotatably connected to the side walls of the plurality of first plates 8 through a plurality of second plates 12.

[0027] After the upper ends of the plurality of arc-shaped plates 9 are attached to the inner top portions below the supporting wheel body 2, the electric push rod 10 is adjusted to be elongated, driving the moving block 11 to move upward, and the moving block 11 drives the plurality of arc-shaped plates 9 to move closer to each other through the plurality of second plates 12 and the plurality of first plates 8, so that the plurality of arc-shaped plates 9 clamp the supporting wheel body 2.

[0028] The lower end of the base 1 is fixedly connected with a motor 13, the movable end of the motor 13 is fixedly connected with a gear 14, the side wall of the cylinder 6 is fixedly connected with a gear ring 15, and the side walls of the gear 14 and the gear ring 15 are engaged.

[0029] When quenching other positions of the wheel body 2, the two cylinders 4 are retracted to separate the wheel body 2 from the middle frequency heating plate 5, then the driving motor 13 is rotated to rotate the cylinder 6 through the gear 14 and the gear ring 15, and then the clamped wheel body 2 is rotated through the annular frame 7, the first plates 8 and the arc-shaped plates 9 to adjust the position of the wheel body 2 facing the middle frequency heating plate 5. After adjustment, the rotation of the motor 13 is stopped, and the two cylinders 4 are extended to make the side wall of the middle frequency heating plate 5 again fit the side wall of the wheel body 2. The side wall of the adjusted wheel body 2 is heated and quenched, and the wheel body 2 is uniformly heated and quenched, and the distance between the middle frequency heating plate 5 and the wheel body 2 does not change, avoiding the distance between the copper ring and the surface of the wheel body greatly increasing when the copper ring moves to the middle part of the wheel body in the prior art. When the distance between the heated copper ring and the workpiece is too large, the LC oscillation current is too large, which affects the service life of the equipment.

[0030] When quenching the wheel body 2, the upper ends of the arc-shaped plates 9 are first fitted to the inner top of the wheel body 2 below, and then the electric push rod 10 is extended to drive the moving block 11 to move upward. At this time, the moving block 11 drives the arc-shaped plates 9 to move closer to each other through the second plates 12 and the first plates 8, so that the arc-shaped plates 9 clamp the wheel body 2;

[0031] Then, the two cylinders 4 are extended to make the side wall of the middle frequency heating plate 5 fit the side wall of the wheel body 2, and the side wall of the wheel body 2 is heated and quenched.

[0032] When quenching other positions of the wheel body 2, the two cylinders 4 are retracted to separate the wheel body 2 from the middle frequency heating plate 5, then the driving motor 13 is rotated to rotate the cylinder 6 through the gear 14 and the gear ring 15, and then the clamped wheel body 2 is rotated through the annular frame 7, the first plates 8 and the arc-shaped plates 9 to adjust the position of the wheel body 2 facing the middle frequency heating plate 5. After adjustment, the rotation of the motor 13 is stopped, and the two cylinders 4 are extended to make the side wall of the middle frequency heating plate 5 again fit the side wall of the wheel body 2. The side wall of the adjusted wheel body 2 is heated and quenched, and the wheel body 2 is uniformly heated and quenched, and the distance between the middle frequency heating plate 5 and the wheel body 2 does not change, avoiding the distance between the copper ring and the surface of the wheel body greatly increasing when the copper ring moves to the middle part of the wheel body in the prior art. When the distance between the heated copper ring and the workpiece is too large, the LC oscillation current is too large, which affects the service life of the equipment.
