Description

Technical Field

[0001] The present invention relates to the technical field of welding systems, and particularly relates to an induction heating welding system for the production of sapphire picks. Background Art

[0002] As is well known, sapphire picks are widely used in the excavation equipment of mining enterprises, especially in application scenarios that require high wear resistance and long service life. Considering the cost of sapphire picks, in most cases, the pick head of the sapphire pick is used in combination with a pick handle, and the pick head and the pick handle are connected by welding. To facilitate the welding operation between the pick head and the pick handle, we propose an induction heating welding system for the production of sapphire picks.

[0003] After retrieval, the patent with the Chinese patent publication number CN105149713A discloses a welding process for a shearer pick head and a pick holder. It is generally described as including a pick handle, a pick holder, and a pick head. The pick holder is connected to one end of the pick handle, and the pick head is fixed in the pick holder. The connection method between the pick head and the pick holder is copper brazing. The welding process is as follows: 1. Open the valve of the welding torch and ignite the welding torch. At this time, black smoke comes out of the welding torch; 2. Rotate the oxygen regulating valve to make the flames on the welding tip of the welding torch evenly distributed, and make the flame temperature of the welding tip reach 2900 - 3100 °C; 3. Use the welding torch to heat the contact part between the pick head and the pick holder and keep the distance between the welding tip and the welding part within 3 - 5 cm. The welding torch should move quickly and evenly to make the contact part evenly heated. Do not let the welding torch stay in one position until it melts; 4. Visually inspect the pick head and the pick holder, locally heat the unfused part, and trim the uneven part; 5. Turn off the welding torch and wait for the welding point to cool down. The welding is completed. The patent with the Chinese patent publication number CN220217305U discloses a pick welding clamping device. It is generally described as including a welding machine drive chain, a clamping table, a drive motor, and a pick body. There is a connecting block above the welding machine drive chain, and a support plate is arranged at the upper end of the connecting block. A clamping table is arranged in the middle above the support plate, and a drive motor is installed in the middle below the support plate. The output end of the drive motor is connected to the lower end of the clamping table. A slot is opened on the surface of the clamping table, and a first servo motor is installed on the side of the clamping table. A first bevel gear is arranged in the middle of the first bidirectional lead screw. When in use, place the pick to be welded in the middle of the clamping rod in the middle of the clamping table. By turning on the first servo motor on the side of the clamping table, the first servo motor drives the first bidirectional lead screw to rotate. The first bevel gear in the middle of the first bidirectional lead screw meshes with the second bevel gear in the middle of the second bidirectional lead screw, so as to facilitate the threaded movement of the first bidirectional lead screw and the second bidirectional lead screw to drive the clamping rod in the middle of the slot on the surface of the clamping table, and then facilitate the four groups of clamping rods to clamp and fix the pick.

[0004] Although the above-mentioned existing coal mining machine pick head and pick seat welding process provides a welding method between the pick head and the pick shank, considering that the pick head and the pick shank are two different materials, when the two are connected by welding, welding separation is very likely to occur due to the different material properties of the two materials. Once welding separation occurs, it will cause a major structural hazard. Although the above-mentioned pick welding clamping device has the corresponding clamping function, its clamping is mainly achieved through the motor lead screw. During operation, it is necessary to consider the power access of the motor in the motion state, and the structural stability and operation safety of the upward cantilevered rotating lead screw also need to be further improved.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] For the embodiment, please refer to Figures 1 - 15, An induction heating welding system for the production of sapphire picks, including a pick handle 1 and a pick head 2 that cooperate with each other, and also including a main frame 3 and a welding processing device. An insertion hole 4 is provided on the pick handle 1, and a plurality of arc-shaped inner convex strips 5 are arranged in the insertion hole 4. A plurality of arc-shaped outer convex strips 6 are fixedly connected to the outside of the pick head 2. The plurality of arc-shaped inner convex strips 5 respectively match the plurality of arc-shaped outer convex strips 6. Through the structural design of the arc-shaped inner convex strips 5 and the arc-shaped outer convex strips 6, a hooking structure between the pick head 2 and the pick handle 1 is formed, so that the connection between the pick head 2 and the pick handle 1 incorporates structural reinforcement, further improving the structural strength between the pick head 2 and the pick handle 1. A spiral filling wire 7 is sleeved outside the pick head 2. An electric rotary workbench is installed on the main frame 3, and a plurality of linkage jigs are installed on the electric rotary workbench. The linkage jigs are used for the clamping and positioning of the pick handle 1. The electric rotary workbench includes an annular frame 10 and a double-sided toothed ring 11. A circular groove cavity 12 is provided at the top of the main frame 3. The annular frame 10 and the double-sided toothed ring 11 are both rotatably connected in the circular groove cavity 12. A plurality of inner opening grooves 13 are provided at the top of the annular frame 10, and a transmission gear 14 is rotatably connected in each of the plurality of inner opening grooves 13. The plurality of transmission gears 14 are all meshed with the double-sided toothed ring 11. A first servo motor 15 and a second servo motor 16 are installed in the main frame 3. An outer bottom ring groove 28 is provided at the bottom of the annular frame 10, and an outer toothed ring 29 is fixedly connected in the outer bottom ring groove 28. The double-sided toothed ring 11 and the outer toothed ring 29 are both meshed with a driving gear 30. The two driving gears 30 are respectively installed on the output shafts of the first servo motor 15 and the second servo motor 16. The first servo motor 15 is used for driving the rotation of the double-sided toothed ring 11, and the second servo motor 16 is used for driving the rotation of the annular frame 10. A weight guiding rod 17 is slidably connected in each of the plurality of transmission gears 14. A central groove is provided at the top of each of the plurality of weight guiding rods 17, and an elastic support column is arranged in each of the plurality of central grooves. The plurality of weight guiding rods 17 respectively match the plurality of linkage jigs. Through the design of the electric rotary workbench, a corresponding installation structure is provided for the plurality of linkage jigs, which is also convenient for the opening and clamping drive of the linkage jigs. At the same time, it can also form the synchronous revolution movement and synchronous self-rotation movement of the plurality of linkage jigs, so as to achieve the sequential passing of the plurality of pick handles 1 through the induction heating coil 8 and the laser welding head 9, and it can also achieve the self-rotation of the plurality of pick handles 1 when passing through the induction heating coil 8 and the laser welding head 9, so as to facilitate improving the uniformity of the welding between the pick head 2 and the pick handle 1 and the coverage of the repair welding treatment.

[0039] It should be further noted that an arc groove opening 25 is provided at the bottom end of the main body frame 3. When the counterweight guide rod 17 rotates past the arc groove opening 25, the supporting effect of the circular groove cavity 12 on the counterweight guide rod 17 fails. Thereafter, under the action of the self-gravity of the counterweight guide rod 17, the counterweight guide rod 17 will relatively drop relative to the transmission gear 14. Under the transmission action of the elastic transmission rod 21, the dropping of the counterweight guide rod 17 will drive a plurality of clamping blocks 20 slidably connected within the same annular seat 19 to move relatively away from each other. At the same time, the auxiliary storage springs 24 connected to the relatively separated plurality of clamping blocks 20 will also assist in realizing the sliding and storage of the clamping blocks 20 relative to the annular seat 19. A groove opening 26 is provided within the circular groove cavity 12, and the groove opening 26 communicates with the arc groove opening 25. A round head block 27 is fixedly connected to the bottom end of the counterweight guide rod 17, and the groove opening 26 matches the round head block 27. Through the guidance of the groove opening on the round head block 27, it is convenient for the round head block 27 to slide into the circular groove cavity 12 from the arc groove opening 25, and finally the counterweight guide rod 17 enters a state of being supported from a state of not bearing bottom support. A plurality of linkage jigs each include a mounting hanging bracket 18, and a plurality of mounting hanging brackets 18 are all fixedly connected to the top end of the annular frame 10. A plurality of annular seats 19 are rotatably connected within a plurality of the mounting hanging brackets 18, and a plurality of clamping blocks 20 are slidably connected within a plurality of the annular seats 19. A plurality of elastic transmission rods 21 are rotatably connected to a plurality of the clamping blocks 20. A plurality of rotation connection grooves 22 are provided at the top ends of a plurality of the counterweight guide rods 17, and a rotation connection shaft 23 is fixedly connected within a plurality of the rotation connection grooves 22. A plurality of the rotation connection shafts 23 are respectively rotatably connected to a plurality of the elastic transmission rods 21. Through the design of the linkage jig, it is convenient for the insertion and clamping positioning of the pick handle 1. When the pick head 2 and the pick handle 1 are welded subsequently, it is convenient for the induction heating coil 8 and the laser welding head 9 to align correctly relative to the pick handle 1, and the practicability is better. A plurality of auxiliary storage springs 24 are fixedly connected within a plurality of the annular seats 19, and a plurality of the auxiliary storage springs 24 are respectively fixedly connected to a plurality of the clamping blocks 20, which is convenient for the storage of the clamping blocks 20 relative to the annular seat 19 where they are located, and further convenient for the failure of the clamping effect of a plurality of the clamping blocks 20 installed within the same annular seat 19. The welding treatment device includes an induction heating coil 8 and a laser welding head 9. The induction heating coil 8 is fixedly connected to the main body frame 3 through a plurality of fixing brackets. The induction heating coil 8 is used for heating and melting the spiral filler wire 7. The laser welding head 9 is installed on the main body frame 3 through an electric inclined adjustment frame. The laser welding head 9 is used for the surface treatment operation at the connection welding part of the pick handle 1 and the pick head 2. Through the design of the welding treatment device, the connection welding operation between the pick handle 1 and the pick head 2 and the repair welding treatment operation at the welding part after welding are completed are supported, forming a coupled welding of heat fusion and trimming, achieving welding connection while forming surface replenishment and strengthening of the welding area, improving the structural characteristics at the connection between the pick head 2 and the pick handle 1, and making the connection reliability between the pick head 2 and the pick handle 1 better and the service life higher.

[0040] It should be further noted that the electric inclined adjustment frame includes a fixed seat 31 which is fixedly connected to the top end of the main frame 3. A rotating frame 32 is rotatably connected to the fixed seat 31, and an electric telescopic rod 33 is installed between the fixed seat 31 and the rotating frame 32. An installation opening 36 is formed at the rear end of the fixed seat 31, and an installation frame 37 is rotatably connected in the installation opening 36. The electric telescopic rod 33 is installed on the installation frame 37. A transmission tail seat 38 is hinged to the telescopic rod of the electric telescopic rod 33, and the transmission tail seat 38 is fixedly connected to the rotating frame 32. By operating the electric telescopic rod 33, the relative inclination angle between the rotating frame 32 and the main frame 3 can be adjusted. A first electric drive slide 34 is installed on the rotating frame 32, a second electric drive slide 35 is installed on the first electric drive slide 34, and the laser welding head 9 is installed on the second electric drive slide 35. While realizing the installation of the laser welding head 9, the position of the laser welding head 9 can be adjusted to facilitate the adjustment of the laser welding head 9 according to the passing position of the matching pick handle 1 and pick head 2. The projection line of the laser beam emitted by the laser welding head 9 on the top end of the main frame 3 intersects and is perpendicular to the axis of the annular frame 10, ensuring that the laser beam emitted by the laser welding head 9 is perpendicular to the outer tangent plane of the pick handle 1 and ensuring the cutting angle of welding. A middle island stepped column 39 is fixedly connected in the circular groove cavity 12, a protective ring plate 40 is fixedly connected to the middle island stepped column 39, and a bent folding plate 41 is fixedly connected to the top end of the protective ring plate 40, forming a shield for the heating area of the induction heating coil 8 and the welding area of the laser welding head 9 to protect the operator.

[0041] The induction heating coil 8, laser welding head 9, first servo motor 15, second servo motor 16, electric telescopic rod 33, first electric drive slide 34 and second electric drive slide 35 in this embodiment are all conventional devices well-known to those skilled in the art and purchased on the market. In the present invention, we only use them and do not improve their structures and functions. Their setting methods, installation methods and electrical connection methods can be debugged and operated by those skilled in the art as long as they follow the requirements of their user manuals, and will not be elaborated here.

[0042] In summary, the working principle of the induction heating welding system for sapphire picks is as follows. During use, first place and install the induction heating welding system for sapphire picks at the required position, and assemble the induction heating coil 8 with the corresponding induction welding machine. Through the operation of the induction welding machine, an alternating magnetic field can be generated in the induction heating coil 8 to achieve the purpose of heating the pick handle 1, pick head 2, and spiral filling wire 7. At the same time, install a laser emitter and a feeder with the laser welding head 9. Through the power-on operation of the laser emitter, the laser welding head 9 can output laser. Through the feeder, it can form an auxiliary conveyance of the welding wire for the laser beam irradiated on the pick handle 1, pick head 2, and spiral filling wire 7, assist in the cloth laying for the welding operation, and install a control circuit for the first servo motor 15, second servo motor 16, electric telescopic rod 33, first electric drive slide 34, and second electric drive slide 35 to achieve the control of the coordinated operation of the first servo motor 15, second servo motor 16, electric telescopic rod 33, first electric drive slide 34, and second electric drive slide 35. Then, the operator forms the clamping and loading of the pick handle 1, pick head 2, and spiral filling wire 7 relative to the linkage fixture from the shielding area of the bending flap 41. Since the arc groove 25 is located in the corresponding area of the shielding area of the bending flap 41, when the weight guiding rod 17 enters the clamping and loading area, the supporting effect of the circular groove cavity 12 on the round head block 27 fails, and the round head block 27 is in a suspended state. In this state, under the action of the self-weight of the weight guiding rod 17 and the pulling force of the auxiliary receiving spring 24, multiple clamping blocks 20 in the same annular seat 19 move relatively away from each other, that is, multiple clamping blocks 20 in the annular seat 19 are all received into the annular seat 19, so the insertable area in the middle of the annular seat 19 becomes larger. Then, insert the pick handle 1 into the annular seat 19, and insert the pick head 2 with the spiral filling wire 7 sleeved into the insertion hole 4.

[0043] Further, when the pick head 2 is inserted relative to the insertion hole 4, the relative dislocation between the arc-shaped inner convex strip 5 and the arc-shaped outer convex strip 6 should be controlled. After the pick head 2 is inserted relative to the insertion hole 4, the pick head 2 is rotated and adjusted relative to the pick shank 1 so that an auxiliary hook is formed between the arc-shaped inner convex strip 5 and the arc-shaped outer convex strip 6. Then, the first servo motor 15 and the second servo motor 16 are started to realize the rotational drive of the two drive gears 30. Under the meshing transmission of the two drive gears 30 with the double-sided tooth ring 11 and the external tooth ring 29 respectively, the operation of the first servo motor 15 realizes the rotational drive of the double-sided tooth ring 11, and the power-on operation of the second servo motor 16 realizes the rotational drive of the annular frame 10. Since multiple transmission gears 14 are all meshed with the double-sided tooth ring 11, when the servo spindles of the first servo motor 15 and the second servo motor 16 rotate synchronously and in the same direction, the annular frame 10 and the double-sided tooth ring 11 also rotate synchronously and in the same direction. During this process, multiple transmission gears 14 rotate synchronously in a circular motion, but multiple transmission gears 14 do not rotate on their own axes. The weight guiding rod 17 slidably connected within the transmission gear 14 will also move synchronously with the transmission gear 14. When the round head block 27 originally in the arc groove opening 25 re-enters the round groove cavity 12 under the guidance of the bevel groove 26, the support of the round groove cavity 12 will cause the round head block 27 to increase in height. During this process, the weight guiding rod 17 fixedly connected to the top of the round head block 27 will also increase in height. The increase in the weight guiding rod 17 drives the elastic transmission rod 21 connected thereto to move. Under the movement transmission of the elastic transmission rod 21, the relative approach of multiple corresponding clamping blocks 20 is realized, and finally the clamping of the pick shank 1 inserted into the corresponding annular seat 19 is formed. During the clamping process, since the part of the weight guiding rod 17 that supports the pick shank 1 is an elastic support column, when the clamping block 20 contacts the pick shank 1 and further applies clamping force, the elastic support column will be elastically compressed to ensure that the weight guiding rod 17 has space for further height increase, thereby facilitating the further clamping force application drive of the corresponding multiple clamping blocks 20.

[0044] Furthermore, along with the movement of the annular frame 10, the movement of multiple annular seats 19 is formed, so that the multiple annular seats 19 pass through the area of the arc slot 25 in sequence, and the annular seats 19 passing through the arc slot 25 are assembled and inserted into the pick handle 1, so as to realize the sequential installation of multiple pick handles 1. When the assembly composed of the pick handle 1, the pick head 2 and the spiral filling wire 7 enters the corresponding operation area of the induction heating coil 8, the induction welding machine is provided to provide the required alternating magnetic field for the induction heating coil 8, so as to form the heating of the overlapping area between the pick handle 1 and the pick head 2 and the melting of the spiral filling wire 7. The melted spiral filling wire 7 will form a flow filling in the insertion hole 4, and at the same time, the first servo motor 15 is controlled to stop, so that the annular frame 10 enters a stationary state from a rotating state. The second servo motor 16 is kept in operation to realize the differential rotational movement between the double-sided gear ring 11 and the annular frame 10. During this process, the multiple transmission gears 14 are driven to rotate, and the counterweight guide rods 17 in the multiple transmission gears 14 also form synchronous rotation, thereby realizing the rotational drive of the multiple annular seats 19, and the pick handle 1 located in the annular seat 19 also forms rotation, and finally achieves dynamic uniform heating between the induction heating coil 8 and the assembly, and improves the heating effect of the welding area between the pick handle 1 and the pick head 2. After that, the first servo motor 15 enters the operation state from the parking state, realizing the synchronous revolution movement of the multiple assemblies. When the assembly rotates to the working area of the laser welding head 9, and the laser beam emitted by the laser welding head 9 is aligned with the outer surface of the pick handle 1 After the section enters a relatively vertical shape, the first servo motor 15 enters the parked state again, the laser emitter and the feeder operate, so that the laser welding head 9 outputs a laser beam, the electric telescopic rod 33, the first electric drive slide 34 and the second electric drive slide 35 operate synchronously to achieve the relative position adjustment of the laser welding head 9 and the assembly, the electric telescopic rod 33 operates to achieve the rotation adjustment of the rotating frame 32 relative to the main frame 3, which is ultimately manifested as the adjustment of the inclination angle of the laser welding head 9, the first electric drive slide 34 operates to achieve the height adjustment of the second electric drive slide 35, which is ultimately manifested as the height adjustment of the laser welding head 9, and the second electric drive slide 35 operates to achieve the direct adjustment of the relative distance between the laser welding head 9 and the assembly, and the electric telescopic rod 33 is used before welding. The telescopic rod 33, the first electrically driven slide 34 and the second electrically driven slide 35 operate synchronously to achieve the focus adjustment of the laser welding head 9 relative to the assembly. During the welding process, the electric telescopic rod 33, the first electrically driven slide 34 and the second electrically driven slide 35 operate synchronously to achieve the adjustment of the welding angle and the formation of the welding trajectory of the laser welding head 9 relative to the assembly, and the second servo motor 16 is powered on to realize the self-rotation and rotation drive of the assembly in the welding state, so as to achieve the complete welding operation of the outer annular surface of the welding point of the inner pick handle 1 and the pick head 2 of the assembly. During the welding process, the feeder can form a matching conveying of the welding wire in the irradiation area of the laser beam to facilitate the auxiliary feeding of the welding layer. After the welding is completed, the first servo motor 15 operates again.Move the assembled parts after welding to the area for clamping and loading. At this time, the supporting function of the counterweight guide rod 17 fails again. After that, the operator removes the assembled parts relative to the corresponding annular seat 19 and inserts the pick holder 1 into the corresponding annular seat 19 again to realize the loading of another assembled part, so as to form the sequential processing of multiple assembled parts.
