[0002] Laser cladding is a process in which external materials are added to a molten pool formed by laser irradiation of a substrate, either simultaneously or pre-placed, and both solidify rapidly to form a cladding layer. Laser cladding technology is widely used in laser cladding of materials such as nickel-based, cobalt-based, iron-based, titanium alloys, copper alloys, particulate metal composites, and ceramics.

Furthermore, traditional laser cladding equipment is not suitable for grinding the laser-clad workpiece, which can lead to burrs on the workpiece surface and hinder the laser cladding process. Therefore, there is an urgent need for a device to solve at least one of the above problems. Summary of the Invention

(Example) Figures 1-6 As shown, the present invention provides a temperature-controlled laser cladding welding device, the temperature-controlled laser cladding welding device comprising:

[0042] Welding box 1, having a working chamber 10;

[0043] The rotating clamping mechanism 2 is disposed in the working cavity 10 and is used to clamp the workpiece and drive the workpiece to rotate.

[0044] The laser cladding mechanism 3 has a laser cladding head 31, which is movably disposed in the working cavity 10 and is used to perform laser cladding welding on the surface of the workpiece while the workpiece is rotating.

[0045] Temperature control mechanism 4 is provided on the laser cladding mechanism 3 and is used to adjust the ambient temperature around the laser cladding head 31 when the laser cladding head 31 performs laser cladding welding.

[0046] The temperature-controlled laser cladding welding equipment provided by this invention includes a welding box 1, and a rotating clamping mechanism 2 is provided in the working cavity 10 of the welding box 1. The rotating clamping mechanism 2 clamps and drives the workpiece to rotate. The laser cladding head 31, which is movably set in the working cavity 10, performs laser cladding welding on the surface of the workpiece during the workpiece rotation. In order to better control the ambient temperature around the laser cladding head 31 and provide a suitable solidification temperature for the cladding layer on the surface of the workpiece after laser cladding welding, a temperature control mechanism 4 is provided on the laser cladding mechanism 3. The ambient temperature around the laser cladding head 31 is adjusted by the temperature control mechanism 4, which solves the problem that the ambient temperature is difficult to control during the laser cladding welding process in the prior art, thus affecting the rapid solidification and formation of the cladding layer, and improves the welding efficiency and welding quality of laser cladding welding.

[0047] In one embodiment, such as Figures 1-2 As shown, the rotary clamping mechanism 2 includes: a driver 21, a tailstock 22, a circular clamping disk 23, and a pair of clamping components 24;

[0048] A pair of clamping assemblies 24 are arranged symmetrically along the radial direction of the clamping disk 23;

[0049] The tailstock 22 is disposed in the working cavity 10; the workpiece is placed between the clamping plate 23 and the tailstock 22, one end of the workpiece is clamped by a pair of clamping components 24 on the clamping plate 23, and the other end is supported by the tailstock 22;

[0050] The driver 21 is disposed in the working cavity 10 and is used to drive the clamping disk 23 to rotate.

[0051] Each clamping assembly 24 includes:

[0052] The electric telescopic rod 241 has a fixed end and a telescopic end. The fixed end is disposed on the clamping plate 23, and the telescopic end can move radially and retract along the clamping plate 23.

[0053] The jaw 242 is disposed at the telescopic end of the electric telescopic rod 241. The electric telescopic rod 241 drives the jaw 242 to move radially along the clamping plate 23 through the telescopic end to clamp or release the workpiece.

[0054] To facilitate workpiece clamping, a receiving hole 231 is provided axially in the clamping disk 23, and a pair of clamping mounting holes 232 are symmetrically provided radially in the clamping disk 23. The pair of clamping mounting holes 232 communicate with the receiving hole 231. The fixed end of the electric telescopic rod 241 of the clamping assembly 24 is fixed in the clamping mounting hole 232, and the telescopic end can move axially in and out of the clamping mounting hole 232. The jaws 242 are located in the receiving hole 231 and are mounted on the telescopic end. When the telescopic ends of the pair of clamping assemblies 24 move axially in the clamping mounting hole 232, they can drive the corresponding jaws 242 to move closer to or away from the center of the receiving hole 231. The workpiece is clamped by the jaws 242 of the pair of clamping assemblies 24 simultaneously moving closer to the center of the receiving hole 231, or the workpiece is released by the jaws 242 of the pair of clamping assemblies 24 simultaneously moving away from the center of the receiving hole 231. Figure 2 As shown, the tailstock 22 includes a tailstock frame 221 and an ejector pin 222. The tailstock frame 221 has an ejector pin mounting hole and is located in the working cavity 10. The ejector pin 222 is movably located in the ejector pin mounting hole and can extend and retract along the axial direction of the ejector pin mounting hole. When the tailstock 22 is installed in the working cavity 10, it is ensured that the ejector pin mounting hole on the tailstock frame 221 of the tailstock 22 is coaxially arranged with the receiving hole 231 of the clamping plate 23. When clamping the workpiece, one end of the workpiece is clamped by the jaws 242 of a pair of clamping components 24, and the other end is clamped by the ejector pin 222, which is movably located in the ejector pin mounting hole, into the process hole opened on the other end face of the workpiece.

[0055] To facilitate laser cladding welding on the workpiece surface, the laser cladding mechanism 3 also includes: a lead screw 32, a lead screw seat 33, a mounting plate 34, a lead screw driver 35, and multiple connecting rods 36.

[0056] Multiple connecting rods 36 are vertically arranged on the lead screw seat 33. The mounting plate 34 is connected to the lead screw seat 33 through multiple connecting rods 36. The laser cladding head 31 is arranged on the mounting plate 34. The lead screw seat 33 is screwed onto the lead screw 32. The lead screw 32 is arranged in the working cavity 10.

[0057] The lead screw driver 35 is used to drive the lead screw 32 to rotate so as to move multiple connecting rods 36, the mounting plate 34 and the laser cladding head 31 along the extension direction of the lead screw 32 via the lead screw seat 33.

[0058] The extension direction of the lead screw 32 is consistent with the axial extension direction of the clamping disk 23 of the rotary clamping mechanism 2, and the center line of the lead screw 32 is parallel to the axis of the clamping disk 23. The lead screw 32 is set above the clamping disk 23, and the lead screw seat 33 is screwed onto the lead screw 32. The lead screw 32 is driven to rotate by the lead screw driver 35, and the lead screw seat 33 can move along the extension direction of the lead screw 32. The mounting disk 34 is connected to the lead screw seat 33 by a plurality of vertically arranged connecting rods 36. The mounting disk 34 is located above the rotary clamping mechanism 2, and the laser cladding head 31 is set on the mounting disk 34. The connecting rods 36 are telescopic rods that can extend and retract in the vertical direction. The extension and retraction of the connecting rods 36 can drive the laser cladding head 31 set on the mounting disk 34 to move closer to or away from the workpiece, which facilitates laser cladding welding.

[0059] During the movement of the lead screw seat 33 along the extension direction of the lead screw 32, to prevent the laser cladding mechanism 3 mounted on the lead screw seat 33 from colliding with the clamping disk 23 or tailstock 22 of the rotary clamping mechanism 2, the temperature-controlled laser cladding welding equipment further includes: a limiting plate 7; the limiting plate 7 has a limiting hole, which limits the movement distance of the lead screw seat 33 in the extension direction of the lead screw 32. Figure 2 As shown, a limiting plate 7 is provided between the lead screw 32 and the rotary clamping mechanism 2. A limiting hole is provided on the limiting plate 7. The size of the limiting hole is set according to the installation distance between the clamping plate 23 and the tailstock 22. During the movement of the lead screw seat 33 along the extension direction of the lead screw 32, the movement distance of the lead screw seat 33 is limited by the limiting hole to avoid interference with the clamping plate 23 or the tailstock 22.

[0060] To grind the surface of the workpiece after welding, the temperature-controlled laser cladding welding equipment further includes a grinding mechanism 5, which is mounted on the mounting plate 34 and used to grind the workpiece surface. The grinding mechanism 5 is mounted on the mounting plate 34 of the laser cladding mechanism 3. The grinding mechanism 5 includes a grinding wheel 51 and a grinding wheel driver 52. The grinding wheel driver 52 is mounted on the mounting plate 34 and drives the grinding wheel 51 to rotate in order to grind the surface of the workpiece after laser cladding welding.

[0061] In one embodiment, such as Figure 5 and Figure 6As shown, the temperature control mechanism 4 includes a U-shaped temperature control frame 41 and a cooling pump. The U-shaped temperature control frame 41 has a cooling channel, and the cooling pump pumps cooling medium into the cooling channel. The U-shaped temperature control frame 41 is detachably mounted on the mounting plate 34 around the laser cladding head 31. The ambient temperature around the laser cladding head 31 is adjusted by the cooling medium flowing in the cooling channel. The U-shaped temperature control frame 41 is detachably mounted on the mounting plate 34, and the mounting plate 34 and the U-shaped temperature control frame 41 together form a welding space. The laser cladding head 31 is located within the welding space. The cooling medium consists of coolant and cooling gas. The cooling pump pumps the cooling medium into the cooling channel, and the ambient temperature within the welding space is adjusted by the cooling medium flowing in the cooling channel. To stabilize the ambient temperature within the welding space, baffles 43 are respectively installed on both sides of the U-shaped temperature control frame 41, and through holes matching the workpiece size are opened on the baffles 43. The two baffles 43 facilitate the adjustment of the welding space. The ambient temperature inside the welding space is more stable. During welding, the workpiece passes through the through hole on the baffle 43, and both ends of the workpiece are clamped or supported by the clamping assembly 24 and the tailstock 22. The lead screw seat 33 drives the laser cladding head 31 to move to the welding position of the workpiece in the extension direction of the lead screw 32 for laser cladding welding. The laser cladding joint 31 is located in the welding space. The temperature in the welding space is regulated by the cooling medium flowing in the cooling channel of the U-shaped temperature control frame 41, thereby accurately controlling the ambient temperature in the welding space within the temperature range suitable for the solidification of the cladding layer, thus improving welding efficiency and welding quality.

[0062] To adjust the ambient temperature within the welding space to a suitable temperature for rapid solidification of the cladding layer, the temperature control mechanism 4 specifically includes a temperature sensor 42, mounted on the mounting plate 34, for measuring the ambient temperature around the laser cladding head 31. By real-time monitoring of the ambient temperature within the welding space using the temperature sensor 42, operators can easily adjust the temperature of the cooling medium entering the cooling channel based on the sensor's readings, thereby controlling the ambient temperature within the welding space.

[0063] like Figure 1 As shown, the temperature-controlled laser cladding welding equipment also includes a welding material supply mechanism 6, which is disposed on the outer surface of the welding box 1 and is used to provide welding material for laser cladding welding.

[0064] The welding material supply mechanism 6 includes: a welding material storage box 61, a delivery pump 62, a delivery pipe 63, and a nozzle 64;

[0065] The welding material storage box 61 is used to store welding materials;

[0066] The nozzle 64 is disposed on the mounting plate 34 and is connected to the delivery pump 62 through the delivery pipe 63. The delivery pump 62 is used to pump the welding material in the welding material storage box 61 to the welding position on the surface of the workpiece through the delivery pipe 63 and the nozzle 64.

[0067] The solder is in powder form. The solder storage box 61 is located on the top of the welding box 1. The delivery pump 62 is located on the top of the welding box 1. In order to avoid dust, the delivery pump 62 is placed in a sealed box 65. The delivery pump 62 pumps the solder in the solder storage box 61 through the delivery pipe 63 and the nozzle 64 to the surface of the workpiece so that the laser cladding head 31 can perform laser cladding welding.

[0068] like Figure 1 As shown, in order to facilitate the observation of the welding status by the staff, an observation window 8 is opened on the wall of the welding box 1 so that the staff can observe the welding status. Multiple support legs are set at the near-ground end of the welding box 1 to support the welding box 1. In order to facilitate the installation of the workpiece onto the rotating clamping mechanism 2 in the working chamber 10 or the removal of the workpiece from the rotating clamping mechanism 2 before cladding welding, a loading door is opened on the wall of the welding box 1. The loading door is opened when installing or removing the workpiece and closed when performing cladding welding.

[0069] The temperature-controlled laser cladding welding equipment provided by this invention includes a rotating clamping mechanism within the working chamber of the welding box to clamp and drive the workpiece to rotate. A laser cladding head is movably positioned within the working chamber and performs laser cladding welding on the workpiece surface during its rotation. To control the ambient temperature around the laser cladding head during welding, thereby assisting in the rapid solidification of the cladding layer, a temperature control mechanism is installed on the laser cladding mechanism. This mechanism adjusts the ambient temperature around the laser cladding head to a suitable temperature for rapid solidification of the cladding layer. This solves the problem in existing technologies where the ambient temperature is difficult to control during laser cladding welding, thus affecting the rapid solidification of the cladding layer and improving both the welding efficiency and quality of laser cladding welding.
