Abstract
Description
Technical Field
[0001] The present application relates to the technical field of laser cladding, and in particular to a rapid cladding structure with dual laser cladding heads. Background Art
[0002] Laser cladding is a surface treatment technology that uses a laser beam to melt metal powder or wire and spray it onto the surface of the substrate to form a uniform and dense coating. This technology can improve the hardness, wear resistance and corrosion resistance of the substrate, while also repairing and reinforcing damaged areas.
[0003] After searching the utility model with announcement number CN218465946U, a dual laser cladding head rapid cladding structure is found, including an equipment base, a workpiece is arranged above the equipment base, and a spindle chassis and a tailstock are respectively installed at both ends of the upper surface of the equipment base. The utility model is provided with a first traverse motor and a second traverse motor, so that the first cladding head and the second cladding head can move left and right smoothly along the axial direction of the workpiece. Assuming that the molten pool width of each cladding head is about 20-26, when the cladding layer of the workpiece needs to be thinner, the cladding layer itself has a higher flatness. At this time, a large spiral is set, such as a pitch of 34-46mm, so that the first cladding head will separate a blank area, and the subsequent second cladding head will also advance with a spiral pitch of 34-46mm to fill the remaining blank area of the first cladding head, and small overlap areas are superimposed on the front and back. The cladding layer can achieve a higher flatness and the overall cladding efficiency can be doubled.
[0004] The above application proposes a double-head cladding method to improve the cladding coverage rate and speed up the cladding efficiency, but its cladding head adopts a dual-drive control method, which increases the control cost. In addition, the use of the cladding head is only suitable for cladding operations outside the workpiece and cannot be adapted to the cladding of the inner wall of pipe workpieces. In this regard, a dual laser cladding head rapid cladding structure is proposed to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0023] See also Figure 1-4 In this embodiment, a dual laser cladding head rapid cladding structure includes a workbench 1, a mounting base installed on the workbench 1, and a laser cladding head body 7 arranged on the mounting base, wherein the laser cladding head body 7 uses a conventional laser cladding head, and its specific laser power, focal length, scanning speed, laser beam diameter and laser wavelength are replaced according to the actual workpiece cladding requirements.
[0024] In this embodiment, the mounting base includes a transverse motor 2 located on the workbench 1, an electric push rod 3 connected to the transverse motor 2, and a first column 4 connected to the output end of the electric push rod 3, wherein the transverse motor 2 specifically uses a linear guide rail so that the transverse motor 2 can flexibly adjust the position of the laser cladding head body 7 relative to the workbench 1.
[0025] It should be noted that a hinge seat 5 is also installed on the first column 4, through which a second column 6 is rotatably installed on the upper end of the first column 4, and a connecting plate 11 is fixedly installed on one end of the second column 6 away from the first column 4 for connecting to the laser cladding head body 7.
[0026] In this embodiment, the external thread of the first column 4 is installed with a locking sleeve 8, and the locking sleeve 8 is threadedly connected to the first column 4 and the second column 6 at the same time. When the locking sleeve 8 rotates and is connected to the first column 4 and the second column 6 at the same time, the first column 4 and the second column 6 can be placed in the same vertical direction.
[0027] See also Figure 3 In another embodiment, an extension plate 9 is fixedly mounted on the upper end of the locking sleeve 8 , and a mechanical clamp 10 is fixedly mounted on the extension plate 9 , and the mechanical clamp 10 corresponds to the size of the second column 6 .
[0028] In a specific implementation, the second column 6 is rotated relative to the first column 4 so that the connecting plate 11 can be tilted onto one side of the first column 4 , and the mechanical clamp 10 is used to restrict the second column 6 so that it can be at a vertical angle relative to the first column 4 .
[0029] The relative angle between the second column 6 and the first column 4 is adjustable, so that the laser cladding head body 7 located on the connecting plate 11 can adjust the angle relative to the first column 4 to extend into the pipeline for cladding or directly process the outer wall of the workpiece.
[0030] In this embodiment, a connecting structure is provided between the laser cladding head body 7 and the second column 6, a groove 12 is recessed in the outer wall of the second column 6, a socket 14 connected to the groove 12 is penetrated through the top of the connecting plate 11, and the connecting structure includes a threaded pin 15 fixedly installed on one side of the laser cladding head body 7, and the threaded pin 15 passes through the socket 14 and extends to the inside of the groove 12.
[0031] It should be noted that a limit block 13 is fixedly installed on the inner wall of the groove 12 , and a gap corresponding to the threaded pin 15 is reserved between the limit blocks 13 , which can facilitate the threaded pin 15 to pass through the gap between the two limit blocks 13 and extend into the groove 12 .
[0032] In this embodiment, a nut 16 is installed on the external thread of the threaded pin 15 for limiting the position of the threaded pin 15 relative to the groove 12 .
[0033] Such a design allows the laser cladding head body 7 to extend into the groove 12 through the threaded pin 15, and then the threaded pin 15 is locked by the nut 16 rotating relative to the threaded pin 15 and abutting against the limit block 13. At this time, the laser cladding head body 7 can be tightly attached to the connecting disk 11 to complete the assembly.
[0034] In this embodiment, four grooves 12 and four insertion holes 14 are provided and arranged in a square. Two threaded pins 15 are provided on the laser cladding head body 7 , and the two threaded pins 15 correspond to the spacing between the two insertion holes 14 .
[0035] In a specific implementation, the connection direction of the laser cladding head body 7 and the connecting plate 11 can be adjusted by adjusting the two sockets 14 corresponding to the laser cladding head body 7, so that the assembly and use thereof are more flexible. For example, when two laser cladding head bodies 7 need to be arranged upper and lower to complete double laser cladding, a gasket can be added between the laser cladding head body 7 and the connecting plate 11 so that the two upper and lower laser cladding head bodies 7 are offset from each other to reserve a cladding gap.
[0036] The working principle of the above embodiment is:
[0037] The relative positions of the first column 4 and the second column 6 are selected according to the workpiece to be processed. That is, when the pipe workpiece needs to be clad, the second column 6 is rotated to a position perpendicular to the first column 4, and the position of the locking sleeve 8 is adjusted. The position of the second column 6 is limited by the mechanical clamp 10 on the top of the extension disk 9 installed on the upper end of the locking sleeve 8. At this time, the two threaded pins 15 on one side of the laser cladding head body 7 are inserted into the corresponding holes 14 on the connecting disk 11, and the threaded pins 15 are locked with nuts 16, so that the laser cladding head body 7 can be easily assembled for use. At the same time, two laser cladding head bodies 7 facing up and down can be continuously arranged on the connecting disk 11 for use, so as to realize rapid cladding of dual laser cladding heads.
