Referring to fig. 1, the present embodiment provides a welding grinding repair device 100 for cone rolls of a ring rolling machine, which includes a frame 110, a working vehicle 120, and a numerical control mechanism 130.
The frame 110 is provided with rails 111, the frame 110 in this embodiment being for supporting the work car body 120 and providing support rails 111 for movement of the work car body 120. In this embodiment, the frame 110 and the rail 111 are disposed vertically on a horizontal plane, and the rail 111 is disposed on an upper surface of the frame 110 and extends out of the frame 110.
Referring to fig. 2 and 3, the working vehicle 120 is a carriage structure as a whole, which can move on the rails 111 of the frame 110. Specifically, the work vehicle body 120 is provided with a traveling wheel 121 and a traveling motor 122 for driving the traveling wheel 121 to move, and the traveling wheel 121 slidably travels on the rail 111. In order to improve the movement precision of the travelling wheel 121, in this embodiment, the working vehicle body 120 is further provided with a travelling gear 123, a rack 112 is further provided below the track 111, the gear 123 is in transmission connection with the travelling motor 122, and the gear 123 is meshed with the rack 112. That is, in the present embodiment, the gear 123 is driven by the traveling motor 122 to rotate so as to move the gear 123 on the rack 112, and the traveling wheel 121 is of an unpowered wheel structure, which is driven by the gear 123 to move on the track 111.
The working car body 120 is provided with a mounting plate 124, and a welding gun 140 and a grinding mechanism 150 which are mounted on the mounting plate 124, wherein the welding gun 140 and the grinding mechanism 150 are fixedly mounted on the mounting plate 124, and the mounting plate 124 can move along with the movement of the working car body 120 so as to drive the welding gun 140 and the grinding mechanism 150 to synchronously move.
In this embodiment, the grinding mechanism 150 is provided with a grinding motor 151 and a grinding wheel 152, the grinding wheel 152 is in transmission connection with the grinding motor 151, the grinding motor 151 can drive the grinding wheel 152 to rotate, and the grinding wheel 152 carries out frosting treatment on the surface contacted with the grinding wheel 152 in the rotating process. The grinding wheel 152 is arranged at the rear end of the welding gun 140 and is used for grinding the welded surface to realize grinding of the welded cone roll 200 of the ring rolling machine; the working vehicle body 120 is further provided with two grinding wheel shields 153, the grinding wheel shields 153 are symmetrically arranged on two sides of the radial direction of the grinding wheel 152, the grinding wheel shields 153 are fixedly connected with the mounting plate 124, the grinding wheel shields 153 can also move along with the movement of the working vehicle body 120, the grinding wheel shields 153 in the embodiment comprise an upper inclined plate 154, a vertical plate 155 and a lower inclined plate 156, the upper inclined plate 154 and the lower inclined plate 156 are inclined towards the direction far away from the grinding wheel 152, and the vertical plate 155 is connected between the upper inclined plate 154 and the lower inclined plate 156. In this embodiment, the vertical plate 155 in the middle of the grinding wheel shield 153 has a small distance from the grinding wheel 152 by the arrangement of the upper inclined plate 154 and the lower inclined plate 156, and the upper inclined plate 154 and the lower inclined plate 156 at two ends have a large distance from the grinding wheel 152, so that the grinding scraps generated in the grinding process are discharged from the bottom or the top without circumferential rotation along with the grinding wheel 152.
Referring to fig. 1 and 4 in combination, in the present embodiment, the track 111 is disposed above the cone roller 200 of the ring rolling machine, and since the working car body 120 is mounted on the track 111, the welding gun 140 and the grinding mechanism 150 are both disposed above the welding gun 140 and the grinding mechanism 150, and the cone roller 200 of the ring rolling machine is provided with a cone roller motor 210 for driving the cone roller to rotate. The cone roller motor 210 drives the cone roller 200 of the ring rolling machine to rotate, and the welding gun 140 and the grinding mechanism 150 which are positioned above the cone roller 200 of the ring rolling machine sequentially weld and grind the cone roller 200 of the ring rolling machine in the process of rotating the cone roller 200 of the ring rolling machine; since the cone roller 200 of the ring rolling machine is tapered, its diameter is gradually reduced along the axial line direction of the cone roller 200 of the ring rolling machine, so that when the cone roller 200 of the ring rolling machine rotates at the same rotation speed, the linear speeds of different positions on the conical surface are different, and the wire-out speed of the welding gun 140 is constant, which results in that the wire-out speed of the welding gun 140 is not matched with the linear speed of the cone roller 200 of the ring rolling machine when the existing welding structure is welded, in this embodiment, the numerical control mechanism 130 is utilized to electrically connect with the travelling motor 122 and the cone roller motor 210. The numerical control mechanism 130 can regulate the rotation speed of the walking motor 122 and the rotation speed of the cone roller motor 210, specifically, the wire-out speed of the welding gun 140 is the same as the linear speed of the cone roller 200 of the ring rolling machine at the wire-out position. The travel motor 122 drives the work vehicle 120 to travel at the same speed as the full rotation of the welding gun 140. That is, when the welding gun 140 rotates the cone roller 200 of the ring rolling machine, the circumference of the cone roller 200 of the ring rolling machine is welded, at this time, the linear speed at the wire outlet position is adjusted by the numerical control mechanism 130 to keep consistent with the wire outlet speed of the welding gun 140, when one circumference of the cone roller 200 of the ring rolling machine is welded by the welding gun 140, the numerical control mechanism 130 drives the traveling motor 122 to move to the next circumference to be welded, at this time, the linear speed at the wire outlet position is adjusted again by the numerical control mechanism 130 to keep consistent with the wire outlet speed of the welding gun 140, so that the wire outlet speed of the welding gun 140 is matched with the linear speed at the wire outlet position of the cone roller 200 of the ring rolling machine, and a better welding effect is achieved.
Further, referring to fig. 1 and 5, since the ring rolling machine cone roll 200 is a cone-shaped mechanism, in the process of moving the working car body 120 to weld and grind, the distance between the welding gun 140 and the ring rolling machine cone roll 200 is changed, which can affect the welding effect and grinding effect to a certain extent, therefore, the working car body 120 of the embodiment is further provided with a lifting mechanism 160 for driving the mounting plate 124 to lift and a distance sensor 170 for detecting the distance between the welding gun 140 and the ring rolling machine cone roll 200, the distance sensor 170 is electrically connected with the numerical control mechanism 130, the numerical control mechanism 130 is electrically connected with the lifting motor 161, in this embodiment, the distance sensor 170 is used to detect the distance between the welding gun 140 and the ring rolling machine cone roll 200, and when the preset distance is not satisfied, the distance sensor 170 controls the lifting mechanism 160 to lift or descend so as to adjust the distance between the mounting plate 124 and the ring rolling machine cone roll 200, and further adjust the distance between the welding gun 140 and the grinding mechanism 150 mounted on the mounting plate 124 and the ring rolling machine cone roll 200. The distance sensor 170 transmits a distance signal to the numerical control mechanism 130, and the numerical control mechanism 130 can determine the rotation speed required at the moment according to the distance signal, so that the rotation speed of the taper roller motor 210 is regulated and controlled.
