[0001] The present invention relates to the technical field of arc welding, in particular to a metal surface heat treatment processing equipment. Background Art
[0002] During the surfacing heat treatment process of the metal surface, when the surfacing path changes due to the change of the equipment movement direction, the surfacing position is easily deviated due to the weak connection between the welding head and the rotation center structure. Especially during the switching of the surfacing direction, this deflection will cause the surfacing layer to have uneven thickness and irregular shape, and even poor bonding between the surfacing layer and the substrate. In order to ensure the quality of the surfacing, when the surfacing path changes, the operator often needs to stop the machine frequently and re-position and adjust the surfacing position, which will not only affect the continuity of the metal surface surfacing process, but also greatly reduce production efficiency.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0019] Example: This example provides a metal surface heat treatment processing equipment, see Figures 1-12 Specifically, it includes a shell 1, a vertically arranged main shaft 101 is fixed on the top of the shell 1, a horizontally arranged first frame 2 is fixed in the main shaft 101, and a first slide 201 is installed in the first frame 2, a welding head 202 with its lower end tilted to the left is installed in the first slide 201, and the lower end of the welding head 202 is located on the central axis of the main shaft 101, a second frame 4 arranged horizontally on the right side of the first frame 2 is installed in the shell 1, and a second slide 401 is installed in the second frame 4, a vertically arranged round table 402 is rotated in the second slide 401, and a vertically arranged vertical pipe 403 is installed through the round table 402, a first flame head 404 is fixed to the bottom end of the vertical pipe 403, and the first flame head 404 is connected to a horizontally arranged connecting pipe 405, and a plurality of second flame heads 406 evenly distributed on both sides of the first flame head 404 are fixed on the connecting pipe 405.
[0020] When the device is in use, the staff installs the device on the arc cladding machine. The arc cladding machine is equipped with an electric slide rail assembly for controlling the movement of the device along the XYZ axis. The electric slide rail assembly is a prior art and will not be described in detail here. The device is connected to the electric slide rail assembly on the arc cladding machine through the main shaft 101, and a servo motor for driving the main shaft 101 to rotate is installed on the electric slide rail assembly, so that the device can be driven to rotate during the controlled movement.
[0021] In this device, by bringing the lower end of the welding head 202 close to the metal surface and cooperating with the continuous feeding operation of the solder supply mechanism in the arc surfacing welding machine, the metal surface and the solder can be heated and melted, and fused together to achieve heat treatment surfacing welding processing on the metal surface. During the actual surfacing welding process, the upper end of the vertical pipe 403 is connected to the fuel supply pipeline, and fuel can be supplied to the first flame head 404 fixed at the lower end of the vertical pipe 403 and the plurality of second flame heads 406 connected to the connecting pipe 405. Through the first flame head 404 and the plurality of evenly distributed The second flame head 406 sprays flame downward to heat the metal surface. During the process of the device being controlled and moved, the first flame head 404 and the second flame head 406 always pass through the position on the metal surface to be welded before the welding head 202. This allows the device to first use the first flame head 404 and the second flame head 406 to preheat the metal surface to increase the temperature of the position on the metal surface to be welded, and then perform the weld deposition process through the welding head 202, which can reduce welding stress and help improve the stability of the metal surface weld deposition process.
[0022] When the surfacing direction needs to be changed, the staff controls the servo motor to drive the spindle 101 to rotate. Through the drive of the servo motor, the spindle 101 drives the shell 1 to rotate and swing. Since the lower end of the welding head 202 is on the central axis of the spindle 101, when the device is controlled to rotate and adjust the direction, the lower end of the welding head 202 will not deviate from the previous welding path, which can effectively ensure the stability and smoothness when switching between surfacing processes in different directions.
[0023] In the device, the spindle 101, the welding head 202 and the first flame head 404 are in the same vertical plane, and the vertical plane is parallel to the housing 1. In the device, by rotating the round table 402 in the second slide 401, the first flame head 404 cooperates with the plurality of second flame heads 406 to preheat the metal surface, which can be flexibly adjusted according to demand. During the process of surfacing welding along a straight line, the connecting pipe 405 can remain parallel to the housing 1. Figure 3 As shown in the structure in the middle, in this state, the first flame head 404 and the plurality of second flame heads 406 cooperate to preheat the metal surface in a straight line.
[0024] When the surfacing direction needs to be changed during the surfacing process, according to the surfacing direction to be changed, the device can first rotate the connecting pipe 405 to a state parallel to the subsequent surfacing path through the rotation of the round table 402, and in the subsequent process, through the coordinated rotation of the main shaft 101 and the round table 402, the rotation angle of the outer shell 1 and the connecting pipe 405 is continuously changed, so that the connecting pipe 405 always remains parallel and directly above the subsequent surfacing path until the lower end of the welding head 202 moves to the surfacing direction switching angle position. When the welding head 202 moves to the surfacing direction switching angle position, the outer shell 1 can be adjusted to a state parallel to the connecting pipe 405 again, and then the device can continue to perform the surfacing processing operation along a straight line. The above operation ensures that the device will not lose the metal surface preheating operation when switching the surfacing direction, which can effectively ensure the stability of the metal surface preheating treatment during the surfacing path switching process.
[0025] When the device performs surfacing processing along a straight line, while adjusting the angle of the connecting pipe 405 by rotating the frustum 402, it can also adjust the width of the preheated metal surface of the first flame head 404 and the plurality of second flame heads 406, so that the device can meet different types of preheating requirements, which is conducive to improving the flexibility of the device in actual use.
[0026] In the specific implementation process, Figure 5 and Figure 8As shown, a longitudinally arranged rotating shaft 203 is fixed on the outer end wall of the welding head 202, and the welding head 202 is rotatably connected to the first slide 201 through the rotating shaft 203. When the device is in use, the welding head 202 is rotatably installed in the first slide 201 through the rotating shaft 203, so that the welding head 202 can swing left and right in the first slide 201, and the inclination angle of the lower end of the welding head 202 is adjusted, so that the device can flexibly adjust the inclination angle between the lower end of the welding head 202 and the metal surface to be welded according to actual needs, which is convenient for adapting to different welding requirements and is conducive to improving the control flexibility of the device during actual use.
[0027] In the specific implementation process, Figure 3 、 Figure 5 and Figure 6 As shown, the first slide 201 is slidably installed in the first frame 2, and a first screw 204 arranged parallel to the first frame 2 is rotated in the first frame 2, and the first screw 204 is threadedly connected to the first slide 201. When the device is in use, after the inclination angle of the welding head 202 is adjusted, the position of the lower end of the welding head 202 will change. In order to ensure that the lower end of the welding head 202 always remains on the central axis of the main shaft 101, the device will control the first slide 201 to move left and right, and fine-tune the position of the lower end of the welding head 202. A servo motor for driving the first screw 204 to rotate is fixed on the first frame 2. After the servo motor is powered on and started, it will drive the first screw 204 to rotate. With the help of the threaded connection between the first screw 204 and the first slide 201, the operation of driving the first slide 201 to move left and right in the first frame 2 is realized.
[0028] In the specific implementation process, Figure 7 As shown, a first spline rod 205 arranged parallel to the first spline rod 205 rotates in the first frame 2, and a first spline cylinder 206 slidably sleeved on the outside of the first spline rod 205 rotates in the first slide 201, and a first worm 207 is fixed on the first spline cylinder 206, and a first worm wheel 208 engaged with the first worm 207 is fixed on the rotating shaft 203. When the device is in use, a servo motor for driving the first spline rod 205 to rotate is fixed on the first frame 2. When the inclination angle of the welding joint 202 needs to be adjusted, the servo motor is powered on and started to drive the first spline rod 205 to rotate, driving the first spline cylinder 206 sleeved on the outside thereof to rotate synchronously, and then with the help of the engagement of the first worm 207 and the first worm wheel 208, the rotating shaft 203 is driven to rotate. By controlling the rotation direction of the servo motor drive shaft, the deflection direction of the welding joint 202 is adjusted.
[0029] In the above-mentioned transmission structure, the internal dimensions of the first spline cylinder 206 are adapted to the external dimensions of the first spline rod 205, so that when the first spline cylinder 206 is slidably mounted on the first spline rod 205, it will not affect the synchronous rotation between the two, nor will it affect the left and right sliding of the first slide 201. At the same time, power is transmitted by means of the engagement of the first worm 207 and the first worm wheel 208. With the one-way self-locking property of the engagement transmission of the first worm 207 and the first worm wheel 208, the welding head 202 will not loosen after the deflection adjustment of the inclination angle. With mutual cooperation, the stability of the device during operation can be effectively improved.
[0030] In the specific implementation process, Figure 2 and Figure 3 As shown, a vertically arranged laser module 3 is fixed at the bottom central axis position of the main shaft 101, and two side-by-side laser rangefinders are fixed at the bottom end of the laser module 3. The laser rangefinder on the right is used to locate the position of the lower end of the welding head 202, and the laser rangefinder on the left is used to locate the position of the metal surface. The left end of the first slide 201 is inlaid with high-transmittance glass 301. When the device is in use, the two laser rangefinders arranged side by side on the left and right sides of the bottom of the laser module 3 emit vertical laser beams downward. The laser beams emitted by the two laser rangefinders have different frequencies, which can avoid mutual interference.
[0031] When the lower end of the welding head 202 is on the central axis of the spindle 101, the laser rangefinder located on the right side illuminates the lower end of the welding head 202, while the laser rangefinder located on the left side does not illuminate the lower end of the welding head 202, but passes over the lower end of the welding head 202 and illuminates the metal surface. In this state, the distance value measured by the laser rangefinder on the right side is significantly smaller than the distance value measured by the laser rangefinder on the left side. If the lower end of the welding head 202 is biased to the left side of the central axis of the spindle 101, the distance values measured by the left and right laser rangefinders are similar. If the lower end of the welding head 202 is biased to the right side of the central axis of the spindle 101, the distance values measured by the left and right laser rangefinders are equal. According to the distance values measured by the two laser rangefinders in the laser module 3, the position of the lower end of the welding head 202 can be accurately and conveniently positioned during the adjustment process, which is conducive to efficiently and conveniently keeping the lower end of the welding head 202 on the central axis of the spindle 101.
[0032] By fixing the high-transmittance glass 301 on the left side of the first slide 201, when the welding head 202 swings counterclockwise toward a vertical state, the laser module 3 is used to perform precise positioning operations on the lower end of the welding head 202 without being blocked by the first slide 201, thereby effectively ensuring the stability of the device during operation.
[0033] In the specific implementation process, Figure 9 and Figure 11As shown, the second slide 401 is slidably installed in the second frame 4, and a second screw 5 arranged parallel to it rotates in the second frame 4, and the second screw 5 is threadedly connected to the second slide 401. When the device is in use, a servo motor for driving the second screw 5 to rotate is fixed on the second frame 4. When the first flame head 404 and a plurality of second flame heads 406 are used to preheat the metal surface, since the second slide 401 is slidably installed in the second frame 4, the device can flexibly adjust the distance between the first flame head 404 and the plurality of second flame heads 406 and the lower end of the welding head 202 according to actual preheating requirements, which can effectively improve the preheating flexibility of the device during surfacing welding. During actual operation, the servo motor is powered on and started to drive the second screw 5 to rotate. With the help of the threaded engagement between the second screw 5 and the second slide 401, the second slide 401 is driven to move in the second frame 4. By controlling the rotation direction of the servo motor drive shaft, the movement direction of the second slide 401 can be controlled.
[0034] In the specific implementation process, Figure 9 、 Figure 11 and Figure 12 As shown, a second spline rod 6 arranged parallel to the second spline rod 6 rotates in the second frame 4, and a second spline cylinder 601 slidably sleeved on the outside of the second spline rod 6 rotates in the second slide 401, and a second worm 602 is fixed on the second spline cylinder 601, and a second worm wheel 603 engaged with the second worm 602 is fixed on the round table 402. When the device is in use, a servo motor for driving the second spline rod 6 to rotate is fixed on the second frame 4. When the rotation of the round table 402 needs to be adjusted, the servo motor is powered on and started to drive the second spline rod 6 to rotate, driving the second spline cylinder 601 sleeved on the outside thereof to rotate, and then providing power for the rotation of the round table 402 with the help of the meshing transmission of the second worm 602 and the second worm wheel 603.
[0035] In the above transmission structure, the internal dimensions of the second spline cylinder 601 are adapted to the external dimensions of the second spline rod 6, so that when the second spline cylinder 601 is slidably mounted on the second spline rod 6, it will not affect the synchronous rotation between the two, nor will it affect the left and right sliding of the second slide 401. At the same time, power is transmitted by means of the engagement of the second worm 602 and the second worm wheel 603. With the one-way self-locking property of the engagement transmission of the second worm 602 and the second worm wheel 603, the round table 402 will not deflect after the rotation adjustment. With the cooperation of each other, the stability of the position adjustment of the first flame head 404 and the plurality of second flame heads 406 during the operation of the device can be effectively improved.
[0036] In the specific implementation process, Figures 9-12As shown, the vertical tube 403 is installed in the circular table 402 for lifting, and the third spline rod 7 arranged parallel to it rotates in the second frame 4. The third spline cylinder 701 slidably sleeved on the outside of the third spline rod 7 rotates in the second slide 401, and a gear 702 is fixed on the third spline cylinder 701. The outer end wall of the vertical tube 403 is equipped with a tooth groove 703 arranged from top to bottom, and the tooth groove 703 is engaged with the gear 702. A third worm gear 704 is fixed at the end of the third spline rod 7. There is a third worm 705 meshing with the third worm gear 704. When the device is in use, the vertical pipe 403 is lifted and installed in the circular table 402. This allows the device to preheat the metal surface. Not only can the position of the first flame head 404 and the plurality of second flame heads 406 be adjusted by rotating the circular table 402, but the position height of the first flame head 404 and the plurality of second flame heads 406 can also be adjusted by lifting the vertical pipe 403, making the device more flexible in preheating the metal surface.
[0037] A servo motor for driving the third worm 705 to rotate is fixed on the second frame 4. When the position height of the first flame head 404 and the second flame head 406 needs to be adjusted, the servo motor is powered on and started, driving the third worm 705 connected to its drive shaft to rotate. With the help of the engagement of the third worm 705 and the third worm wheel 704, the third spline rod 7 is driven to rotate, and then the third spline cylinder 701 sleeved on the outside of the third spline rod 7 is driven to rotate. With the help of the engagement of the gear 702 and the tooth groove 703, the vertical pipe 403 is driven to move up and down in the truncated table 402. By controlling the rotation direction of the servo motor drive shaft, the lifting direction of the vertical pipe 403 is controlled, and then the position height of the first flame head 404 and the plurality of second flame heads 406 are adjusted.
[0038] In the above transmission structure, the internal size of the third spline cylinder 701 is adapted to the external size of the third spline rod 7, so that when the third spline cylinder 701 is slidably mounted on the third spline rod 7, it will not affect the synchronous rotation between the two, nor will it interfere with the left and right sliding of the second slide 401. At the same time, power is transmitted by means of the engagement of the third worm gear 704 and the third worm 705. The one-way self-locking property of the engagement transmission of the third worm gear 704 and the third worm 705 ensures that the vertical pipe 403 will not loosen after the lifting and lowering adjustment. With the cooperation of each other, the stability of the device during operation when adjusting the height of the first flame head 404 and the plurality of second flame heads 406 can be effectively improved.
[0039] In the specific implementation process, Figure 12As shown, a vertical chute 604 is provided on the outer end wall of the vertical tube 403, a slider 605 adapted to the chute 604 is fixed in the circular table 402, and a tooth groove 703 is provided around the outer end wall of the vertical tube 403. When the device is used, the sliding connection between the slider 605 and the chute 604 allows the vertical tube 403 to rotate normally during the rotation of the circular table 402, and the positions of the first flame head 404 and the plurality of second flame heads 406 can be stably adjusted by the rotation of the circular table 402. With the help of the sliding connection between the slider 605 and the slide groove 604, the vertical tube 403 can be smoothly raised and lowered in the truncated table 402, so that the rotation of the truncated table 402 will not interfere with the raising and lowering of the vertical tube 403. At the same time, by surrounding the tooth groove 703 on the outer end wall of the vertical tube 403 and the width of the slide groove 604 being smaller than the thickness of the gear 702, the vertical tube 403 will not interfere with the meshing of the gear 702 and the tooth groove 703 when the rotation is adjusted. With mutual cooperation, the stability of the device during operation can be effectively improved.
[0040] Specifically, the working principle and operation method of the present invention are as follows: The device is rotatably mounted on an electric slide assembly in an arc cladding machine via a spindle 101, and the spindle 101 is connected to a servo motor. During cladding processing, the device can be controlled to move horizontally and vertically and to be raised and lowered by the electric slide assembly. The flames ejected from the first flame head 404 and the plurality of second flame heads 406 can be used to preheat the metal surface at the position to be cladding. The lower end of the welding head 202 can then be manipulated to approach the metal surface, and the continuous feeding operation of the solder supply mechanism in the arc cladding machine can be coordinated to heat and melt the metal surface and fuse them together to achieve heat treatment cladding processing on the metal surface. During the cladding process, the deflection of the welding head 202 can be used to adjust the contact between the welding head 202 and the metal surface. The inclination angle of the metal surface can be detected by the laser module 3 and the movement of the second slide 401, so that the welding head 202 can be repositioned on the central axis of the main shaft 101. The position of the first flame head 404 and the plurality of second flame heads 406 can be adjusted by the rotation of the round table 402 to adjust the preheating range of the metal surface. The position height of the first flame head 404 and the plurality of second flame heads 406 can be adjusted by the lifting and lowering of the vertical pipe 403. The distance between the first flame head 404 and the plurality of second flame heads 406 and the lower end of the welding head 202 can be flexibly adjusted by the movement of the second slide 401, so that the device is more flexible when performing surfacing heat treatment on the metal surface.
