Description

Technical Field

[0001] The invention belongs to the field of continuous casting roller welding robots, and more specifically, relates to an auxiliary slag removal device of a continuous casting roller welding robot. Background Art

[0002] The continuous casting roller is an important equipment component in the steel-out area of ​​the continuous casting equipment. It is subjected to high temperature friction and hot and cold fatigue for a long time, and needs to have very good resistance to high temperature, friction and fatigue. Therefore, the surface of the continuous casting roller needs to be clad with a certain thickness of high-hardness wear-resistant material to ensure the special performance requirements of the continuous casting roller. Due to the high performance requirements of the continuous casting roller cladding layer, manual cladding cannot meet them well. It can also be completed by a special cladding machine, but the cladding machine has high cost, low flexibility, and low equipment utilization when there are not many orders. A continuous casting roller welding robot came into being.

[0003] During the continuous casting roller surfacing process, the welding wire will produce some slag on the surface after it melts and solidifies again. At the same time, in order to achieve a certain welding thickness, the welding machine needs to perform multiple layers of welding on the continuous casting roller. Therefore, in order to ensure the welding quality, the slag produced during the previous layer of welding needs to be cleaned before welding. Traditional slag cleaning is generally done by manual knocking. In order to improve the automation level of continuous casting roller surfacing, the continuous casting roller welding slag needs to be automatically cleaned, so this automatic slag removal device is designed. Summary of the invention

[0004] The present invention provides a continuous casting roller welding robot-assisted slag removal device to solve the above-mentioned technical problems, and specifically adopts the following technical solutions:

[0005] A continuous casting roller welding robot auxiliary slag removal device comprises two L-shaped columns, which are arranged opposite to each other; the top ends of the L-shaped columns are connected to support seats; the first guide rails are arranged opposite to each other above the support seats; the tops of the first guide rails are slidably connected to the first sliders; the first sliders are fixed with a moving seat; the tops of the moving seats are arranged opposite to each other; the tops of the second guide rails are slidably connected to the second sliders; the second sliders are fixed with a connecting plate above the second sliders; the connecting box is fixed with an installation box above the connecting plate; the front end surface of the installation box is provided with a vibrating shovel for knocking welding slag; the front end surface of the installation box is provided with a vibrating shovel at both sides of the vibrating shovel There is a chip blowing nozzle; the rear end face of the mounting box is connected to a motor; support rods are arranged opposite to each other at the two ends of the bottom of the mounting box; connecting sleeves are fixed on the tops of the support rods; vibration shafts are slidably connected in the two connecting sleeves; one end of the vibration shaft away from the motor extends out of the mounting box and is fixedly connected to the vibration shovel; a circular ring is fixedly installed between the two vibration shafts; an eccentric wheel is rotatably connected in the circular ring; the output end of the motor is connected to one end of the first rotating shaft; the other end of the first rotating shaft is connected to one end of the bevel gear; the other end of the bevel gear is fixedly connected to one end of the second rotating shaft; the other end of the second rotating shaft is fixedly connected to the rotation center of the eccentric wheel.

[0006] As a preferred technical solution of the present invention, four first sliding blocks and four second sliding blocks are provided.

[0007] As a preferred technical solution of the present invention, limit plates are installed at both ends of the first guide rail and the second guide rail.

[0008] As a preferred technical solution of the present invention, the extension direction of the first guide rail is perpendicular to the extension direction of the second guide rail.

[0009] As a preferred technical solution of the present invention, a fixing hole for fixing the device to the ground is formed at the bottom of the L-shaped column.

[0010] As a preferred technical solution of the present invention, the side of the chip blowing nozzle close to the installation box is parallel to the vibrating shovel; there is a bend in the middle of the chip blowing nozzle; and the extension direction of the side of the chip blowing nozzle away from the installation box is biased towards the vibrating shovel.

[0011] As a preferred technical solution of the present invention, the ring and the vibration shaft are fixed as a whole.

[0012] The method for using the continuous casting roller welding robot auxiliary slag removal device includes the following method: after adjusting the position of the installation box on the second guide rail according to the size of the continuous casting roller, the motor is started. The motor drives the first rotating shaft, and the first rotating shaft drives the second rotating shaft through the bevel gear, thereby driving the eccentric wheel to rotate. The rotating eccentric wheel drives the ring and the vibration shaft as a whole to reciprocate back and forth, thereby driving the vibration shovel to vibrate and knock the welding slag in the welding process.

[0013] The benefit of the present invention lies in that the continuous casting roller welding robot auxiliary slag removal device provided is provided with two guide rails, which can realize horizontal and vertical movement. The horizontal movement can follow the position of the welding gun during the welding process to adjust the position of the vibrating shovel. The vertical movement can make the device suitable for continuous casting rollers of different diameters, which is more practical. In addition, the vibrating shovel installed in the device has a vibration function, which can vibrate and knock the welding slag during the welding process, so that the welding slag breaks and falls off. In this way, the continuous casting roller welding slag can be automatically cleaned, which saves labor costs and greatly improves economic benefits, and improves the versatility of the device. On the other hand, the chip blowing nozzle has a blowing function, which can blow off the broken welding slag in time. In this way, the welding slag is prevented from sticking to the continuous casting roller, resulting in a decrease in the quality of subsequent surfacing. The device can improve the quality of layer-by-layer surfacing, reduce the error rate, and improve practicality. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the motor 22 will adjust the position of the installation box 19 on the first guide rail 13 according to the position of the welding gun during the welding process, thereby adjusting the position of the vibration shovel 20.

[0030] The device is provided with two guide rails, which can realize horizontal and vertical movement. The horizontal movement can adjust the position of the vibration shovel 20 according to the position of the welding gun during the welding process.

In this way, the welding slag is prevented from sticking to the continuous casting roller, resulting in a decrease in the quality of subsequent surfacing. The device can improve the quality of layer-by-layer surfacing, reduce the error rate, and improve practicality.
