Description

Technical Field

[0001] This invention belongs to the field of casting processing technology, and specifically relates to a cooling device for processing automotive castings. Background Technology

[0002] Automotive castings refer to the blanks of automotive parts formed by pouring molten metal into a mold and allowing it to cool and solidify. Processing them involves a series of precise mechanical cutting methods to transform them into final parts that meet the design drawings, have high-precision dimensions, specific surface finishes, and functional characteristics. Since casting is a violent heat exchange process, the cooling device uses a circulating medium in the cooling pipes inside the mold to remove the large amount of heat released by the molten metal, thereby keeping the mold within the optimal operating temperature range, preventing overheating, and establishing a stable thermal equilibrium.

[0003] Chinese patent CN115673298B discloses a cooling device for processing automotive castings. This application injects coolant into the interior of the cooling component and uses thermally conductive silicone pads on the surface of the cooling component to contact the automotive casting. This satisfies the cooling requirements while avoiding direct contact between the automotive casting and the coolant, eliminating the need for subsequent drying processes after coolant adheres to the automotive casting.

[0004] There are many castings used in automobile production, and the materials used for different castings are not the same. For example, the rotor needs to be made of cast copper. When cooling these castings, in addition to using a high-temperature mold temperature controller for overall thermal balance, a spot cooler or spot cooling pipe is also needed to enhance the cooling of the parts with the most concentrated heat. Since the hot spots of the castings are slightly different each time they are processed, the castings need to be slightly adjusted in position each time they are cooled. The position of the rotor, which is cylindrical in shape, is not easy to adjust flexibly, which results in the cooling effect of the hot spots of the rotor being unsatisfactory. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a cooling device for processing automotive castings.

[0006] The technical solution adopted to solve the above-mentioned technical problems is: a cooling device for automotive casting processing, comprising a spot cooler and several cast copper rotors.

[0007] The side wall of the spot cooler is equipped with a display screen and a controller. An electric drive turntable is rotatably installed inside the spot cooler. Several clamping blocks are fixedly installed on the electric drive turntable. Each clamping block holds a cast copper rotor. A spot cooling tube is also installed inside the spot cooler. The spot cooling tube is inclined and faces one of the cast copper rotors. An optical pyrometer is fixedly installed at the top inside the spot cooler. The optical pyrometer is also facing the position of the cast copper rotor that the spot cooling tube is pointing to.

[0008] The clamping block includes a bottom support block and two side clamping blocks. The bottom support block has a cavity inside, and a lifting frame is movably arranged in the cavity. A lifting mechanism is installed at the bottom of the lifting frame, and a rotation drive mechanism for driving the cast copper rotor to rotate is provided in the lifting frame.

[0009] The two side clamping blocks are slidably connected to the top of the bottom support block, and the two side clamping blocks abut against the two sides of the cast copper rotor. The side clamping blocks have a central hole and two side holes on the side wall facing the cast copper rotor. The two side holes are arranged longitudinally, and the central hole is arranged laterally. The two side holes are located on both sides of the central hole. Multi-directional rollers are rotatably arranged in the side holes, and a transverse drive wheel is rotatably arranged in the central hole.

[0010] By using the above technical solution, a rotatable electric drive turntable and a clamping block that can flexibly drive the cast copper rotor are installed in the spot cooling machine, so that the spot cooling pipe can more accurately perform targeted cooling work on the hot spots of the cast copper rotor.

[0011] Furthermore, the lifting mechanism includes a bottom dual-axis motor, a central gear, a lifting screw, a lifting threaded sleeve, two side gears, and two telescopic round rods. The central gear is rotatably connected to the bottom of the cavity. Two bottom grooves are formed at the bottom of the cavity. The two telescopic round rods are slidably connected to the inside of the two bottom grooves respectively. The two side gears are fixedly connected to the side walls of the two telescopic round rods respectively. The central gear meshes with both side wall gears. One output end of the bottom dual-axis motor is fixedly connected to the side wall of the central gear, and the other end is fixedly connected to the lifting screw. The lifting threaded sleeve is fixedly installed at the bottom of the lifting frame, and the lifting screw is threadedly connected to the inside of the lifting threaded sleeve.

[0012] Through the above technical solution, the operation of the bottom dual-axis motor will cause the central gear to rotate, and the side gear meshing with it will drive the telescopic rod to rotate together. The cooperation between the bottom groove and the telescopic rod allows the telescopic rod and the side gear to move laterally along the bottom groove together, thereby satisfying the purpose of opening the two side clamping blocks. At the same time, the cooperation between the lifting screw and the lifting threaded sleeve also allows the operation of the bottom dual-axis motor to drive the lifting frame to rise and fall simultaneously.

[0013] Furthermore, the bottom of the lifting frame has two horizontal slots, and the two telescopic rods extend out from the two horizontal slots respectively.

[0014] With the above technical solution, the horizontal groove is designed so that the telescopic rod can extend out of the lifting frame. Therefore, the operation of the bottom dual-axis motor can be transmitted to the side clamping block above the bottom support block through the telescopic rod. In addition, the width of the horizontal groove is also greater than the outer diameter of the telescopic rod. Therefore, the telescopic rod will not generate unnecessary friction with the inner wall of the horizontal groove when it moves laterally.

[0015] Furthermore, the rotation drive mechanism includes a top dual-axis motor, two extension rods, two ratchet wheels, two drive bevel gears, two driven bevel gears, two rotating rods, four drive screws, four drive blocks, and four telescopic drive rods. The two output ends of the top dual-axis motor are respectively fixedly connected to the two extension rods. The two extension rods pass through the two ratchet wheels respectively. The end of the extension rod away from the dual-axis motor is fixedly connected to the drive bevel gear. The driven bevel gear is fixedly connected to the side wall of the rotating rod and meshes with the drive bevel gear. The two drive screws are respectively fixedly disposed at both ends of the rotating rod. The two drive screws located at both ends of the same rotating rod have opposite thread directions. The two drive blocks are respectively threadedly connected to the two drive screws. The two telescopic drive rods are respectively fixedly disposed on the top of the two drive blocks. The end of the two telescopic drive rods away from the drive blocks is respectively fixedly connected to the bottom of the side clamping block.

[0016] Through the above technical solution, the operation of the top dual-axis motor will drive the extension rod to rotate. When the top dual-axis motor rotates in the forward direction, the ratchet will rotate synchronously, and the extension rod will also drive the drive bevel gear to rotate. The driven bevel gear meshing with it will drive the rotating rod and the drive screw to rotate together, thereby causing the two drive blocks to drive the two telescopic drive rods to move away from each other, and causing the two side clamping blocks to also move away from each other, thus releasing the clamped cast copper rotor. When the top dual-axis motor rotates in the reverse direction, the ratchet will not rotate, but the extension rod will still drive the drive bevel gear to rotate. After a series of transmissions, the two side clamping blocks will move closer to each other, thereby clamping the cast copper rotor.

[0017] Furthermore, the ratchet includes an axially rotating wheel, an inner ratchet tooth, a center wheel, and two pawls. The inner ratchet tooth is fixedly disposed on the side wall of the axially rotating wheel. The center wheel is fixedly connected to the side wall of the extension rod. The two pawls are rotatably connected to the side wall of the center wheel, and the two pawls abut against the side wall of the inner ratchet tooth. The two axially rotating wheels abut against the side wall of the cast copper rotor.

[0018] With the above technical solution, when the extension rod is driven to rotate in the forward direction by the top dual-axis motor, the center wheel fixedly connected to the extension rod will drive the pawl to move in the opposite direction to the inner ratchet. At this time, the inner ratchet will be driven to rotate, which in turn will drive the axial rotating wheel to rotate at the same time. When the top dual-axis motor rotates in the reverse direction, the center wheel will drive the pawl to slide past the inner ratchet. At this time, the inner ratchet and the axial rotating wheel will not rotate.

[0019] Furthermore, the center wheel has a rotating groove on its side wall, a fixed rod is fixedly installed in the rotating groove, the pawl is sleeved on the outside of the fixed rod, and a torsion spring is provided between the pawl and the fixed rod.

[0020] Through the above technical solution, the force applied to the pawl by the torsion spring will keep the pawl in a state of contact with the inner ratchet. At the same time, the setting of the rotating groove will also make the pawl supported by the rotating groove when rotating in the forward direction, thereby better driving the inner ratchet to rotate.

[0021] Furthermore, the bottom support block has two rotating holes at its top, and two axial rotating wheels extend from the two rotating holes respectively. The bottom support block also has four transverse holes at its top, and four telescopic drive rods pass through the four transverse holes respectively.

[0022] With the above technical solution, the bottom support block is equipped with many components, but only two components extend out of the bottom support block: the axial rotating wheel and the telescopic drive rod. The rotation of the axial rotating wheel will drive the cast copper rotor to rotate axially, which will facilitate the cooling of different positions on the side wall of the cast copper rotor by the spot cooling pipe. The movement of the telescopic drive rod can drive the side clamping block to move laterally, thereby clamping or releasing the cast copper rotor.

[0023] Furthermore, both the transverse drive wheel and the multi-directional roller abut against the side wall of the cast copper rotor, and the transverse drive wheel and the multi-directional roller extend beyond the side clamping block by the same distance.

[0024] With the above technical solution, the transverse drive wheel and the multi-directional roller will contact the cast copper rotor simultaneously. Therefore, both can drive the cast copper rotor to move or be driven by the cast copper rotor to move. The multi-directional roller has no driving component, so it can only move passively. The shape of the multi-directional roller allows it to move axially with the cast copper rotor, or rotate laterally with the cast copper rotor when the transverse drive wheel drives the cast copper rotor to move laterally.

[0025] Furthermore, the end of the telescopic rod away from the bottom groove passes through the bottom of the side clamping block and is fixedly connected to the side wall of the transverse drive wheel, and the side wall of the transverse drive wheel is provided with a friction layer.

[0026] With the above technical solution, the transverse drive wheel is driven by the telescopic rod. Therefore, when the dual-axis motor at the bottom is running, it can drive the transverse drive wheel to rotate laterally. The friction layer set on the side wall of the transverse drive wheel can increase the friction of the transverse drive wheel, thereby facilitating the transverse movement of the cast copper rotor.

[0027] Furthermore, the lifting threaded sleeve is located below the top dual-axis motor, and the two transverse slots are located on both sides of the top dual-axis motor.

[0028] Through the above technical solution, the setting of the lifting threaded sleeve allows the bottom dual-axis motor to drive the lifting screw to rotate, thereby driving the lifting frame to rise and fall. This causes the axial rotating wheel that was originally against the cast copper rotor to retract into the bottom support block, thus facilitating the lateral drive wheel to drive the cast copper rotor to move laterally.

[0029] The beneficial effects of this invention are as follows:

[0030] (1) By setting a rotatable electric drive turntable in the spot cooling machine, the present invention allows the operator to put multiple cast copper rotors into the spot cooling machine at the same time, thereby improving the cooling efficiency of the cast copper rotor. The clamping block of the cast copper rotor can be flexibly driven, which can help the cast copper rotor to rotate axially and move laterally, so that the spot cooling pipe can more accurately perform targeted cooling work on the hot spots of the cast copper rotor.

[0031] (2) The present invention provides a transverse drive wheel and a multi-directional roller on the side wall of the side clamping block, so that the transverse drive wheel and the multi-directional roller contact the cast copper rotor at the same time. Therefore, both can drive the cast copper rotor to move or be driven by the cast copper rotor to move. The multi-directional roller has no drive component, so it can only follow the cast copper rotor to move passively. At the same time, the shape of the multi-directional roller allows it to move axially with the cast copper rotor, and it can also rotate laterally with the cast copper rotor when the transverse drive wheel drives the cast copper rotor to move laterally.

[0032] (3) By setting an axial rotating wheel, a lifting frame and a transverse driving wheel on the side wall of the side clamping block in the bottom support block, the rotation of the cast copper rotor is sequential. It needs to move laterally first and then move axially. The cast copper rotor is driven to a designated position by the bottom dual-axis motor. Then, the top dual-axis motor is needed for axial movement. When driving the cast copper rotor to rotate axially, the two side clamping blocks will move away from each other. At this time, the transverse driving wheel will not affect the axial rotation of the cast copper rotor. The position of the cast copper rotor will remain between the two axial rotating wheels due to friction. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0045] like Figure 1 - Figure 2 As shown, this embodiment provides a cooling device for automotive casting processing, including a spot cooler 1 and several cast copper rotors 2. The side wall of the spot cooler 1 is provided with a display screen 3 and a controller 4. An electric drive turntable 5 is rotatably installed inside the spot cooler 1. The electric drive turntable 5 is a common component. In this application, the function of the electric drive turntable 5 is only to be able to rotate and stop at a fixed point. Therefore, the specific principle and components are not described in detail here.

[0046] Several clamping blocks are fixedly installed on the electric drive turntable 5, each clamping a cast copper rotor 2. The spot cooling machine 1 is also equipped with a spot cooling pipe 6, which is inclined and driven by the spot cooling machine 1. The inclined setting is to avoid directly rinsing the hot spots, thereby preventing internal cracks. The spot cooling pipe 6 is directly facing one of the cast copper rotors 2. An optical pyrometer 7 is fixedly installed above the inside of the spot cooling machine 1, and the optical pyrometer 7 is also directly facing the position of the cast copper rotor 2 pointed to by the spot cooling pipe 6. The optical pyrometer 7 is a typical non-contact temperature measuring instrument with a generally high temperature range, which is more suitable for monitoring the hot spots of the cast copper rotor 2. The optical pyrometer 7 is electrically connected to the display screen 3, so the operator can directly see the temperature distribution of the cast copper rotor 2 on the display screen 3.

[0047] refer to Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown in the content, the clamping block includes a bottom support block 8 and two side clamping blocks 9. The bottom support block 8 has a cavity inside, within which a lifting frame 10 is movably mounted. A lifting mechanism is installed at the bottom of the lifting frame 10. The lifting mechanism includes a bottom dual-axis motor 15, a central gear 16, a lifting screw 17, a lifting threaded sleeve 18, two side gears 19, and two telescopic round rods 20. The central gear 16 is rotatably connected to the bottom of the cavity. Two bottom grooves 21 are formed at the bottom of the cavity. The two telescopic round rods 20 are slidably connected to the interior of the two bottom grooves 21. The two side gears 19 are fixedly connected to the side walls of the two telescopic round rods 20. The central gear 16 meshes with both side wall gears. The bottom dual-axis motor 15... One output end is fixedly connected to the side wall of the central gear 16, and the other end is fixedly connected to the lifting thread. The lifting thread sleeve 18 is fixedly installed at the bottom of the lifting frame 10. The lifting screw 17 is threadedly connected to the inside of the lifting thread sleeve 18. The operation of the bottom dual-axis motor 15 will cause the central gear 16 to rotate, and the side gear 19 meshing with it will drive the telescopic round rod 20 to rotate together. The cooperation between the bottom groove 21 and the telescopic round rod 20 will allow the telescopic round rod 20 and the side gear 19 to move laterally along the bottom groove 21, thereby satisfying the purpose of opening the two side clamping blocks 9. At the same time, the cooperation between the lifting screw 17 and the lifting thread sleeve 18 will also cause the operation of the bottom dual-axis motor 15 to drive the lifting frame 10 to rise and fall simultaneously.

[0048] from Figure 4 As can be seen, the bottom of the lifting frame 10 has two horizontal slots 22, and two telescopic rods 20 extend from the two horizontal slots 22 respectively. The horizontal slots 22 allow the telescopic rods 20 to extend from the lifting frame 10. Therefore, the operation of the bottom dual-axis motor 15 can be transmitted to the side clamping block 9 above the bottom support block 8 through the telescopic rods 20. In addition, the width of the horizontal slots 22 is also greater than the outer diameter of the telescopic rods 20. Therefore, the telescopic rods 20 will not generate unnecessary friction with the inner wall of the horizontal slots 22 when moving laterally.

[0049] from Figure 6 As can be seen from the content, the lifting threaded sleeve 18 is located below the top dual-axis motor 23, and the two transverse grooves 22 are located on both sides of the top dual-axis motor 23. The setting of the lifting threaded sleeve 18 allows the bottom dual-axis motor 15 to drive the lifting frame 10 to rise and fall by driving the lifting screw 17 to rotate when it is running. This causes the axial rotating wheel 31, which was originally against the cast copper rotor 2, to retract into the bottom support block 8. Therefore, the transverse drive wheel 14 can easily drive the cast copper rotor 2 to move laterally.

[0050] Reference Figure 4It is known that the lifting frame 10 is equipped with a rotation drive mechanism for driving the cast copper rotor 2 to rotate. The rotation drive mechanism includes a top dual-axis motor 23, two extension rods 24, two ratchet wheels, two drive bevel gears 25, two driven bevel gears 26, two rotating rods 27, four drive screws 28, four drive blocks 29, and four telescopic drive rods 30. The two output ends of the top dual-axis motor 23 are respectively fixedly connected to the two extension rods 24. The two extension rods 24 pass through the two ratchet wheels respectively. The end of the extension rod 24 away from the dual-axis motor is fixedly connected to the drive bevel gear 25. The driven bevel gear 26 is fixedly connected to the side wall of the rotating rod 27. The driven bevel gear 26 meshes with the drive bevel gear 25. The two drive screws 28 are respectively fixedly installed at both ends of the rotating rod 27. The two drive screws 28 located at both ends of the same rotating rod 27 have opposite thread directions. The two drive blocks 29 are respectively threadedly connected to the two drive screws 28. Each telescopic drive rod 30 is fixedly mounted on the top of the two drive blocks 29. The ends of the two telescopic drive rods 30 away from the drive blocks 29 are fixedly connected to the bottom of the side clamping blocks 9. The operation of the top dual-axis motor 23 will drive the extension rod 24 to rotate. When the top dual-axis motor 23 rotates in the forward direction, the ratchet will rotate synchronously. At the same time, the extension rod 24 will also drive the drive bevel gear 25 to rotate. The driven bevel gear 26 meshing with it will drive the rotating rod 27 and the drive screw 28 to rotate together. This will cause the two drive blocks 29 to drive the two telescopic drive rods 30 to move away from each other, and the two side clamping blocks 9 will also move away from each other, thereby releasing the clamped cast copper rotor 2. When the top dual-axis motor 23 rotates in the reverse direction, the ratchet will not rotate, but the extension rod 24 will still drive the drive bevel gear 25 to rotate. After a series of transmissions, the two side clamping blocks 9 will move closer to each other, thereby clamping the cast copper rotor 2.

[0051] Combination Figure 4 and Figure 5 As can be seen from the content, the ratchet includes an axial rotating wheel 31, an inner ratchet 32, a central wheel 33, and two pawls 34. The inner ratchet 32 ​​is fixedly mounted on the side wall of the axial rotating wheel 31. The central wheel 33 is fixedly connected to the side wall of the extension rod 24. The two pawls 34 are rotatably connected to the side wall of the central wheel 33, and the two pawls 34 abut against the side wall of the inner ratchet 32. The two axial rotating wheels 31 abut against the side wall of the cast copper rotor 2. When the extension rod 24 is driven to rotate forward by the top dual-axis motor 23, the central wheel 33, which is fixedly connected to the extension rod 24, will drive the pawls 34 to move against the inner ratchet 32. At this time, the inner ratchet 32 ​​will be driven to rotate, which will cause the axial rotating wheel 31 to rotate simultaneously. When the top dual-axis motor 23 rotates in the opposite direction, the central wheel 33 will drive the pawls 34 to slide past the inner ratchet 32. At this time, the inner ratchet 32 ​​and the axial rotating wheel 31 will not rotate.

[0052] The center wheel 33 has a rotating groove 35 on its side wall. A fixed rod 36 is fixedly installed in the rotating groove 35. The pawl 34 is sleeved on the outside of the fixed rod 36. A torsion spring 37 is installed between the pawl 34 and the fixed rod 36. The force applied by the torsion spring 37 to the pawl 34 will keep the pawl 34 in abutting state with the inner ratchet 32. At the same time, the rotating groove 35 also provides support for the pawl 34 when it rotates in the forward direction, thereby better driving the inner ratchet 32 ​​to rotate.

[0053] from Figure 3 As can be seen, the bottom support block 8 has two rotating holes 38 on its top, and two axial rotating wheels 31 extend from the two rotating holes 38 respectively. The bottom support block 8 also has four transverse holes 39 on its top, and four telescopic drive rods 30 extend from the four transverse holes 39 respectively. The bottom support block 8 has many components inside, but only two types of components extend from the bottom support block 8: the axial rotating wheels 31 and the telescopic drive rods 30. The rotation of the axial rotating wheels 31 will drive the cast copper rotor 2 to rotate axially, which will facilitate the cooling pipe 6 to cool different positions on the side wall of the cast copper rotor 2. The movement of the telescopic drive rods 30 can drive the side clamping block 9 to move laterally, thereby clamping or releasing the cast copper rotor 2.

[0054] Reference Figure 3 , Figure 9 and Figure 10 As can be seen from the content, the two side clamping blocks 9 are slidably connected to the top of the bottom support block 8, and the two side clamping blocks 9 abut against the two sides of the cast bronze rotor 2. The side wall of the side clamping block 9 facing the cast bronze rotor 2 has a central hole 11 and two side holes 12. The two side holes 12 are arranged vertically, and the central hole 11 is arranged horizontally. The two side holes 12 are located on both sides of the central hole 11. Multi-directional rollers 13 are rotatably arranged in the side holes 12, and a transverse drive wheel 14 is rotatably arranged in the central hole 11. The transverse drive wheel 14 and the multi-directional rollers 13 are rotatably arranged in the central hole 11. All three abut against the side wall of the cast copper rotor 2. The transverse drive wheel 14 and the multi-directional roller 13 extend beyond the side clamping block 9 by the same distance. The transverse drive wheel 14 and the multi-directional roller 13 will contact the cast copper rotor 2 simultaneously. Therefore, both can drive the cast copper rotor 2 to move or be driven by the cast copper rotor 2 to move. The multi-directional roller 13 has no driving component, so it can only move passively. The shape of the multi-directional roller 13 allows it to move axially with the cast copper rotor 2, and it can also rotate laterally with the cast copper rotor 2 when the transverse drive wheel 14 drives the cast copper rotor 2 to move laterally.

[0055] The end of the telescopic rod 20 away from the bottom groove 21 passes through the bottom of the side clamping block 9 and is fixedly connected to the side wall of the transverse drive wheel 14. The side wall of the transverse drive wheel 14 is provided with a friction layer 40. The transverse drive wheel 14 is driven by the telescopic rod 20. Therefore, when the bottom dual-axis motor 15 is running, it can drive the transverse drive wheel 14 to rotate laterally. The friction layer 40 provided on the side wall of the transverse drive wheel 14 can increase the friction of the transverse drive wheel 14, thereby facilitating the transverse movement of the cast copper rotor 2. At the same time, a friction layer 40 can also be provided on the side wall of the axial rotating wheel 31 to increase the friction between it and the cast copper rotor 2.

[0056] The working principle of this embodiment is as follows: First, the operator needs to use a robotic arm (not shown in the figure) to place the cast copper rotor 2 onto the electric drive turntable 5 in the spot cooling machine 1. By driving the bottom dual-axis motor 15, the side clamping block 9 clamps the cast copper rotor 2 (the specific working steps of the bottom dual-axis motor 15 are disclosed below). Then, the operator can observe the hot spot location on the cast copper rotor 2 through the optical pyrometer 7. During the observation process, if you want to observe the different positions of the cast copper rotor 2 in detail, you can drive the cast copper rotor 2 to move by first moving laterally and then moving axially.

[0057] To drive the cast copper rotor 2 to move laterally, the bottom dual-axis motor 15 needs to be started. The forward rotation of the bottom dual-axis motor 15 will cause the central gear 16 to rotate, and the side gear 19 meshing with it will drive the telescopic rod 20 to rotate as well. At the same time, the engagement of the lifting screw 17 and the lifting threaded sleeve 18 will also cause the bottom dual-axis motor 15 to drive the lifting frame 10 to descend, causing the axial rotating wheel 31, which was originally in contact with the cast copper rotor 2, to move away. At this time, the position of the cast copper rotor 2 will be changed by the lateral drive wheel 14 and the multi-directional roller. The rotation of the telescopic rod 20, restricted by wheel 13, causes the transverse drive wheel 14 to rotate, thereby driving the cast copper rotor 2 to move laterally. Therefore, in order for the optical pyrometer 7 to more comprehensively monitor the hot spots of the cast copper rotor 2, the cast copper rotor 2 should not be placed in the middle of the side clamping block 9, but should be placed away from the cooling tube 6, so that the transverse drive wheel 14 can drive it to move towards the cooling tube 6, thereby facilitating the optical pyrometer 7 to more comprehensively monitor the entire cast copper rotor 2.

[0058] After the optical pyrometer 7 has finished monitoring all the positions on this side of the cast copper rotor 2, it can drive the bottom dual-axis motor 15 to rotate in the opposite direction. The above steps will be reversed, which will cause the cast copper rotor 2 to return to the initial position, and the axial rotating wheel 31 will also return to the state of contact with the cast copper rotor 2.

[0059] To make the cast copper rotor 2 move axially again, the top dual-axis motor 23 needs to be started. The forward rotation of the top dual-axis motor 23 will drive the extension rod 24 to rotate. The center wheel 33, which is fixedly connected to the extension rod 24, will drive the pawl 34 to move against the inner ratchet 32. At this time, the inner ratchet 32 ​​will be driven to rotate, which will also drive the axial rotation wheel 31 to rotate. At the same time, the extension rod 24 will also drive the drive bevel gear 25 to rotate. The driven bevel gear 26 that meshes with it will drive the rotating rod 27 and the drive screw 28 to rotate together. This will cause the two drive blocks 29 to drive the two telescopic drive rods 30 to move away from each other, and the two side clamping blocks 9 will also move away from each other, thereby releasing the clamped cast copper rotor 2. At the same time, the cast copper rotor 2 will also be driven to rotate axially by the axial rotation wheel 31.

[0060] When the top dual-axis motor 23 rotates in the opposite direction, the ratchet will not rotate, but the extension rod 24 will still drive the drive bevel gear 25 to rotate. After a series of transmissions, the two side clamping blocks 9 will move closer to each other, thereby clamping the cast copper rotor 2. At this time, the optical pyrometer 7 can measure the temperature of the surface of the rotated cast copper rotor 2. In any step, as long as the optical pyrometer 7 detects a severely hot spot, the staff can start the cooling pipe 6 through the controller 4 to focus on cooling that location.

[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
