Abstract
Description
Technical Field
[0001] The invention relates to the technical field of laser processing, and in particular to a high-efficiency cooling device for laser cladding. Background Art
[0002] Laser cladding is a material surface modification technology, also known as laser cladding or laser spray deposition. This technology uses a high-energy-density laser beam as a heat source to heat a specific alloy powder or coating material to a molten state, and quickly solidifies it on the surface of the base material to form a coating with excellent performance. This process can not only improve the surface wear resistance, corrosion resistance, high temperature resistance and other properties of the base material, but also repair worn or damaged parts and extend their service life. A large amount of heat is generated during the cladding process, and the cooling device can ensure the quality of the cladding layer and protect related components from thermal damage.
[0003] In the existing patent 202210677978.6, the present invention discloses a laser cladding cooling device, including a first mounting frame, a first motor is fixed to the outer wall of one side of the first mounting frame, the output end of the first motor is rotatably connected to a rotating disk, a clamping mechanism for fixing the part to be processed is provided on the outer wall of one side of the rotating disk, and an annular linkage disk is embedded on the outer wall of one side of the rotating disk. The present invention can make the first motor drive the part to be processed to rotate through the clamping mechanism by setting the first motor, the clamping mechanism and other structures. Since the annular linkage disk is provided, the annular linkage disk rotates with the rotating disk, so that the linkage ball moves back and forth, driving the fixed disk on the linkage rod to periodically approach the support frame, thereby periodically squeezing the elastic bag, so that the gas in the elastic bag is discharged from the injection pipe, thereby realizing the cooling treatment of the parts being processed above.
[0004] In the above structure, the workpiece can be cooled, but the temperature cannot be controlled or adjusted. Since laser cladding requires high temperature to heat the workpiece so that the workpiece and the coating material are melted, when the workpiece temperature drops to the laser cladding temperature after blowing, the workpiece and the coating material cannot be melted, resulting in difficulty in quickly combining the coating and the workpiece, affecting the quality of the workpiece and reducing the processing efficiency. If the temperature is high, the workpiece and the coating melt quickly, extending the cooling time, which is not conducive to the formation of standard processed parts and may even cause deformation of the processed parts.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0035] Embodiment 1:
[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, a laser cladding high-efficiency cooling device of the present invention comprises a bearing plate 1, a support ring 2 is symmetrically arranged on the bearing plate 1, a rotating ring disk 3 is connected to the bearing on the support ring 2, a driving mechanism 4 for driving the rotating ring disk 3 to rotate is arranged on the support ring 2, and a clamping assembly 5 for clamping a workpiece is arranged on the rotating ring disk 3;
[0037] A laser output device 6 for processing a workpiece is arranged on the carrier plate 1;
[0038] A support plate 7 is arranged on the rotating ring disk 3, a sliding assembly 8 is arranged on the support plate 7, and a cooling assembly 9 for cooling the workpiece is arranged at the output end of the sliding assembly 8;
[0039] The support plate 7 is provided with a pushing component 10 acting on the sliding component 8, and the end of the pushing component 10 is provided with a temperature sensing component 11 close to the workpiece, and the temperature sensing component 11 is used to sense the output temperature of the laser output device 6;
[0040] A compression assembly 12 for compressing the cold air in the cooling assembly 9 is arranged on the rotating ring disk 3, so that the cooling assembly 9 continuously outputs cold air to the workpiece.
[0041] Working principle: When laser cladding is performed on a workpiece, the workpiece is passed through the rotating ring disk 3, and the workpiece is clamped by the clamping component 5. The driving mechanism 4 is started, and the driving mechanism 4 drives the rotating ring disk 3 to rotate, forcing the workpiece to rotate. The laser output device 6 is used to perform cladding processing on the workpiece in all directions. The rotation of the rotating ring disk 3 drives the compression component 12 to move. Due to the continuous output of the laser output device 6, the temperature gradually increases. It is necessary to control the temperature within a certain range to ensure the effective combination of the workpiece and the coating. The compression component 12 acts to compress the cold air of the cooling component 9, forcing the cold air to cool the workpiece to adjust the temperature. When the temperature rises above the normal range, the high temperature causes the temperature sensing component 11 to sense the high temperature value, causing the temperature sensing component 11 to expand, forcing the pushing component 10 to move, and the pushing component 10 drives the sliding component 8 to move. The sliding component 8 forces the cooling component 9 to approach the laser output device 6, and the compression component 12 maintains normal operation, so that the cooling component 9 continues to blow air to reduce the temperature; when the temperature drops to the normal range, the low temperature causes the temperature sensing component 11 to sense the low temperature value, causing the temperature sensing component 11 to shrink, forcing The pushing component 10 moves in the reverse direction, and the pushing component 10 drives the sliding component 8 to move in the reverse direction. The sliding component 8 forces the cooling component 9 to move away from the laser output device 6, and the compression component 12 keeps working normally, so that the cooling component 9 continues to blow air, so that the temperature gradually rises, so that the temperature is maintained within a normal range, which is conducive to the combination of the workpiece and the coating; when each workpiece needs to be cooled, the laser output device 6 is stopped, so that the cooling component 9 cools the workpiece to complete the laser cladding processing of the workpiece; in summary, a laser cladding high-efficiency cooling device of the present application utilizes the rotation of the device to process the surroundings of the workpiece while allowing the cooling component 9 to continue to blow cold air to adjust the output temperature of the laser output device 6. When the temperature is high, the cooling component 9 approaches the workpiece to reduce the temperature. When the temperature is low, the cooling component 9 and the workpiece there increase the temperature, so that the temperature is always maintained within the normal range. Within the ideal temperature range, it is conducive to the effective combination of the coating and the workpiece, improving the quality of the workpiece, improving the processing efficiency, facilitating the rapid cooling of the coating and the workpiece, reducing deformation, and facilitating the formation of standard processed parts.

[0049] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, a laser cladding high-efficiency cooling device of the present invention, the pushing component 10 includes a cylinder body 1001 arranged on a support plate 7, the cylinder body 1001 is filled with gas, a pushing plug 1002 adapted to the cylinder body 1001 is arranged in the cylinder body 1001, a pushing rod 1003 penetrating the cylinder body 1001 is arranged on the pushing plug 1002, and a transmission component 14 is arranged between the pushing rod 1003 and the movable rod 803.
[0050] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, a laser cladding high-efficiency cooling device of the present invention, the transmission assembly 14 includes a fixed plate 1401 arranged on the support plate 7, a rotating gear 1402 is connected to the bearing on the fixed plate 1401, a straight rack 1403 meshing with the rotating gear 1402 is arranged on the push rod 1003, and a straight rack 2 1404 meshing with the rotating gear 1402 is arranged on the movable rod 803, and the straight rack 1403 and the straight rack 2 1404 are located on both sides of the rotating gear 1402.
[0051] like Figure 2 , Figure 3 and Fig. 9 As shown, a high-efficiency cooling device for laser cladding of the present invention, the temperature sensing component 11 includes a heat-conducting rod 1101 arranged on a cylinder body 1001, a heat-conducting rod 1102 is arranged on the heat-conducting rod 1101, the heat-conducting rod 1102 is close to the laser output device 6, and an airbag 1103 is arranged on the heat-conducting rod 1101, the airbag 1103 is located in the gas area inside the cylinder body 1001, and the airbag 1103 has a temperature-sensitive characteristic, wherein when the temperature exceeds the variable temperature range of the airbag 1103, the airbag 1103 will expand, otherwise, the airbag 1103 will shrink.
[0052] Working principle: When laser cladding is performed on a workpiece, the workpiece is passed through the rotating ring disk 3 and the support ring 2, and the electric push rod 501 is started. The output end of the electric push rod 501 drives the slide bar 502 to move on the rotating ring disk 3, and the slide bar 502 causes the chuck 503 to move. Multiple chucks 503 are synchronously approached to the workpiece until they are fitted with the workpiece to form a clamp for the workpiece;
[0053] Since the workpiece needs to be processed on all sides, the motor 401 is started, and the output shaft of the motor 401 rotates to drive the driving gear 402 to rotate, and the rotating gear 1402 drives the driven gear ring 403 to rotate, so that the rotating ring disk 3 rotates. Under the clamping action of the chuck 503, the rotating ring disk 3 forces the workpiece to rotate, and the laser output device 6 is used to perform laser cladding processing on the workpiece;
[0054] Since the laser output device 6 continuously outputs, the temperature rises. It is necessary to control the temperature within a normal range to ensure the effective combination of the workpiece and the coating. As the rotating ring disk 3 rotates, the abutment rod 1301 contacts the contact head 1302, so that the abutment rod 1301 exerts a force on the contact head 1302. At this time, the electromagnet is energized so that the support plate 7 attracts and limits the slider 802 to prevent the slider 802 from sliding in the slide groove 801. The abutment rod 1301 squeezes the contact head 1302, and the abutment head drives the compression rod 1202 to move. The spring 1203 is compressed, and the compression rod 1202 drives the piston 1201 to move, so that the piston 1201 squeezes the horizontal cylinder 903, forcing the gas in the horizontal cylinder 903 to be compressed into the longitudinal cylinder 904, and the gas is ejected from the air nozzle 906 to the processing position of the workpiece.
[0055] The air pump 902 is started, and the air pump 902 inflates the refrigerating box 901. The refrigerating system cools the gas in the refrigerating box 901. When the abutting rod 1301 is separated from the contact head 1302, the circuit of the electromagnet is disconnected, and the limiting effect of the contact support plate 7 on the slider 802 allows the slider 802 to slide in the slide groove 801. Since the abutting rod 1301 is separated from the contact head 1302, the spring 1203 returns to its original state, and the spring 1203 drives the contact head 1302 to move, drives the compression rod 1202 to retreat, and causes the piston 1201 to retreat, so that the volume in the transverse cylinder 903 and the longitudinal cylinder 904 increases. Under the action of the air guide pipe 905, the cold air enters the longitudinal cylinder 904, so that when the gas is ejected, the cold air is blown out, and the cold air is continuously blown out during the continuous rotation of the rotating ring disk 3.
[0056] During the power-off process of the electromagnet, when the resistance rod 1301 is separated from the contact head 1302, the output temperature of the laser output device 6 or the temperature of the workpiece processing location is adjusted. When the temperature rises, the heat-conducting rod 1102 transfers the temperature to the heat-conducting rod 1101, and the heat is transferred to the airbag 1103 through the action of the heat-conducting rod 1101. The airbag 1103 can be set as a thermosensitive polymer material. Since the airbag 1103 has a temperature-sensitive property, when the temperature exceeds the normal temperature, the airbag 1103 expands. The expansion of the airbag 1103 causes the volume in the cylinder 1001 to decrease, and the gas needs to restore the original air pressure, which causes the gas to push the plug 1002. The push plug 1002 generates a force to drive the push rod 1003 to move, so that the push rod 1003 drives the spur rack 1 1403 to move, and under the action of the fixed plate 1401, the rotating gear 1402 rotates, so that the spur rack 2 1404 moves, and the spur rack 2 1404 drives the movable rod 803 to move. Since the slider 802 is released from the limit at this time, the movable rod 803 drives the slider 802 to move in the slide groove 801, and the slider 802 drives the horizontal cylinder 903, the longitudinal cylinder 904 and the air nozzle 906 to approach the workpiece processing position, so that the air nozzle 906 sprays cold air, so that the cold air is quickly blown to the workpiece, and the cooling effect is achieved;
[0057] When the temperature drops below the normal temperature, the heat conducting rod 1102 transfers the low temperature to the heat conducting rod 1101, and the heat is transferred to the airbag 1103 through the action of the heat conducting rod 1101. The airbag 1103 can be set as a thermosensitive polymer material. Since the airbag 1103 has temperature-sensitive characteristics, when the temperature is lower than the normal temperature, the airbag 1103 shrinks. The shrinkage of the airbag 1103 causes the volume in the cylinder 1001 to increase and the pressure to decrease. The gas needs to restore the original air pressure, causing the push plug 1002 to push back, and the push plug 1002 drives the push rod 1003 to move, so that the push rod 1003 drives the spur rack 1403 to move. Under the action of the fixed plate 1401, the rotating gear 1402 rotates in the opposite direction, so that the straight rack 1404 moves, and the straight rack 1404 drives the movable rod 803 to move. Since the slider 802 is released from the limit at this time, the movable rod 803 drives the slider 802 to move in the slide groove 801, and the slider 802 drives the horizontal cylinder 903, the longitudinal cylinder 904 and the air nozzle 906 away from the workpiece processing position. The distance that the cold air sprayed by the air nozzle 906 contacts the workpiece becomes longer, and the cooling effect slows down, so that the temperature slowly increases, and the heating effect is achieved, thereby achieving the temperature regulation effect, forcing the temperature to always be within the normal ideal range;
[0058] When the horizontal cylinder 903 moves, the compression rod 1202 and the contact head 1302 will move. Since the length of the abutment rod 1301 is greater than the width of the contact head 1302, the abutment rod 1301 and the contact head 1302 are always in a state of contact and compression.
[0059] When each part of the workpiece needs to be cooled, the laser output device 6 is stopped, so that the cooling component 9 cools the workpiece, completes the laser cladding processing of the workpiece, realizes the temperature regulation, forces the processing temperature to always be within the normal ideal range, is conducive to the effective combination of the coating and the workpiece, improves the quality of the workpiece, improves the processing efficiency, is conducive to the rapid cooling of the coating and the workpiece, reduces the deformation phenomenon, and is conducive to the formation of standard processed parts;

The air is continuously squeezed out from the transverse cylinder 903 or the longitudinal cylinder 904, so that the cold air is continuously blown to the workpiece processing part; the setting of the contact component 13 can transmit the rotational force of the rotating ring disk 3, change the direction of action, and transform the circular motion into linear motion, so that the compression rod 1202 drives the piston 1201 to squeeze the cold air in the transverse cylinder 903, and the length of the resistance rod 1301 is greater than the width of the contact head 1302, so that the device always moves in a reasonable state, that is, when the transverse cylinder 903 moves, the resistance rod 1301 can always squeeze the contact head 1302, improve the rationality of the device, and make the device work continuously; the setting of the pushing component 10 converts the gas expansion activity into a driving force, so that the push plug 1002 moves , so that the gas reaches equilibrium and generates a force; the setting of the transmission component 14 facilitates the transmission of the driving force to the movable rod 803, so that the direction of the force is changed, so that the movable rod 803 moves in the opposite direction to the push rod 1003, which is beneficial to the temperature regulation; the setting of the temperature sensing component 11 can sense the temperature, so that the device controls the temperature. When the temperature is within the normal range, the device works normally. When the temperature is not within the normal range, the device adjusts the temperature to within the normal range, so that the processing temperature of the workpiece is always within the normal ideal range, which is beneficial to the effective combination of the coating and the workpiece, improves the quality of the workpiece, improves the processing efficiency, is beneficial to the rapid cooling of the coating and the workpiece, reduces deformation, and is beneficial to the formation of standard processed parts.
