Description

Technical Field

[0001] The utility model relates to the field of laser cladding processing, in particular to a chiller unit used for laser cladding processing. Background Art

[0002] Laser cladding refers to placing the selected coating material on the surface of the coated substrate in different filling methods (synchronous powder feeding or pre-placed powder), and using high-energy laser beam irradiation to form a metallurgical bond with the substrate material, thereby significantly improving the heat resistance, corrosion resistance, wear resistance, and oxidation resistance of the substrate material surface. Due to the laser cladding process, the laser cladding head generates a lot of heat. If it is not cooled in time, it is easy to cause damage, and a chiller is needed to cool it down.

[0003] For example, the patent document with the announcement number CN215571520U discloses a water chiller for laser cladding processing, in which the first serpentine pipe flows back into the water tank, and the heat dissipation area of ​​the water tank is enhanced under the action of the heat sink, which helps to dissipate the heat of the cooling water in the water tank. When the temperature sensor detects that the temperature in the water tank is higher than the set value, the controller controls the fan to cool the cooling water flowing back from the first serpentine pipe. However, the unit uses a fixed cooling pipe, and the cooling area is also a fixed area, so the scope of application is small. Utility Model Content

Therefore, they should not be understood as limitations on the present invention.

[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1 - Figure 4 As shown, a chiller for laser cladding processing includes a square frame 100, universal wheels 400 are installed at the four corners of the square frame 100, a cooling mechanism is provided on the upper side of the square frame 100, and the cooling mechanism includes equidistantly distributed cooling pipes 201, the number of cooling pipes 201 is a cardinality, the front and rear ends of the cooling pipes 201 are fixedly connected with T-tubes 202, a telescopic pipe 203 is provided between adjacent T-tubes 202, both ends of the telescopic pipe 203 are fixedly connected with the T-tubes 202, the outer ports of the T-tubes 202 on both sides are closed, the lower end of the T-tube 202 is fixedly connected with a limiting block 206, the T-tube 202 in the middle of the front side is interspersed with a water inlet pipe 204, and the T-tube 202 in the middle of the rear side is interspersed with a water outlet pipe 205, the bottom of the cooling pipe 201 is provided with equidistantly distributed scissor-type telescopic components, the lower side of the scissor-type telescopic components is provided with a threaded component, the front side of the threaded component is provided with a power component, and a valve mechanism is provided on the water inlet pipe 204.

[0025] The water inlet pipe 204 is used for the coolant to enter, the water outlet pipe 205 is used for the coolant to be discharged, the T-tube 202 is used to connect the cooling tube 201 and the telescopic tube 203, when the distance between the cooling tubes 201 increases, the telescopic tube 203 becomes longer accordingly, so as to realize the circulation of the coolant. The limiting block 206 is used to maintain the connection between the T-tube 202 and the frame 100.

[0026] The middle limiting block 206 is fixedly connected to the square frame 100 , and the other limiting blocks 206 are slidably connected to the square frame 100 in the transverse direction.

[0027] The limiting block 206 in the middle is used to maintain the fixed connection between the T-tube 202 and the frame 100 , and the other limiting blocks 206 keep the T-tube 202 able to slide laterally along the edge of the frame 100 , so as to facilitate the adjustment of the distribution range of the cooling tube 201 .

[0028] The scissor-type telescopic assembly includes a rotating shaft 207, which is fixedly connected to the middle of the lower surface of the cooling tube 201. The rotating shaft 207 is rotatably connected to two cross-distributed scissor plates 209. A rotating shaft 208 symmetrically distributed front and back is provided between the scissor-type telescopic assemblies. The rotating shaft 208 is rotatably connected to the adjacent two ends of the scissor plates 209.

[0029] The rotating shaft 207 is used to rotate the middle part of the scissor plate 209, and the rotating shaft 208 is used to hinge the two ends of the scissor plate 209. When the hinges of the scissor plates 209 are close to each other, the middle parts of the scissor plates 209 are driven to move away from each other at an equal distance, so that the cooling tube 201 is moved away from each other at an equal distance, and the cooling range of the cooling tube 201 is increased.

[0030] The threaded assembly includes a bidirectional threaded rod 210 , both ends of which are threadedly connected with threaded sleeves 211 , and the threaded sleeves 211 are fixedly connected to the second rotating shaft 208 on the same side.

[0031] When the bidirectional threaded rod 210 rotates, the threaded sleeves 211 move closer to or farther from each other.

[0032] The power assembly includes a motor 212 , the output shaft of the motor 212 is fixedly connected to the bidirectional threaded rod 210 , the motor 212 is fixedly connected to a transverse slide 213 , and the transverse slide 213 is slidably connected to the frame 100 .

[0033] The motor 212 provides rotational power to drive the bidirectional threaded rod 210 to rotate. At the same time, when the threaded sleeves 211 approach each other, they will also drive the bidirectional threaded rod 210 and the motor 212 to slide horizontally. The horizontal slide plate 213 is used to maintain the horizontal sliding of the motor 212.

[0034] The valve mechanism includes a valve 303 , which is serially connected to the middle of the water inlet pipe 204 . The bottom end of the control shaft of the valve 303 is fixedly connected to a gear 302 , which is meshed with a rack 301 , and the rack 301 is fixedly connected to the transverse slide 213 .

[0035] Valve 303 is used to control whether coolant enters and the coolant flow rate. When the transverse slide plate 213 slides, it drives the rack 301 to move laterally and meshes with the gear 302 to rotate. The rotation of the gear 302 can adjust the cooling flow rate in the valve 303, thereby realizing the linkage between the cooling range adjustment and the coolant flow adjustment.

[0036] Working principle:

[0037] According to the cooling range, the range of the cooling tube 201 is adjusted, and the motor 212 is started to drive the bidirectional threaded rod 210 to rotate, so that the threaded sleeves 211 are moved closer or farther away from each other, and then the second shaft 208 is moved closer or farther away from each other. When the second shaft 208 is moved closer to each other, the scissor plate 209 drives the first shaft 207 to move away from each other, and then the cooling tubes 201 are also moved away from each other, so that the cooling range of the cooling tube 201 is increased. At the same time, the motor 212 and the horizontal slide plate 213 will also slide horizontally, driving the rack 301 to slide horizontally, so that the gear 302 rotates, and the valve 303 is adjusted to increase the flow of coolant in the water inlet pipe 204, so as to maintain the cooling effect of the single cooling tube 201.

[0038] When the motor 212 rotates in the opposite direction, it drives the second shaft 208 to move away from each other. Driven by the scissor plate 209, the first shaft 207 moves closer to each other, and then the cooling pipe 201 also moves closer to each other. The motor 212 and the horizontal slide 213 move in the opposite direction, and the valve 303 is adjusted by the rack 301 and the gear 302 to reduce the cooling range of the cooling pipe 201 and reduce the coolant flow in the water inlet pipe 204, which can not only maintain the cooling effect of the cooling pipe 201, but also save energy.

[0039] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
