Description

Technical Field

[0001] The invention relates to the technical field of speed reducer installation, and more specifically, to a speed reducer output flange shaft installation device. Background Art

[0002] Flange shaft reducers usually have a compact structure and large torsional rigidity, suitable for high torque applications. The design of the flange output shaft allows the reducer to save installation space and is easy to combine with other components such as gears, couplings, etc.

[0003] There are many methods for installing the output flange shaft, including hot installation and cold installation. Hot installation is a commonly used bearing installation method, which is particularly suitable for bearings with large interference fit or difficult to install by press fitting. It is especially suitable for the installation of the output flange shaft of the reducer. The hot installation method uses the principle of thermal expansion and contraction. By heating the bearing or bearing seat, the inner ring expands, making it easier to install.

[0004] At present, the installation of output flange shafts on the market usually adopts heating equipment such as heating spray guns to heat the bearings of the output flange shaft. When heated to a certain temperature, the heated bearings are put on the outside of the output flange shaft and then cooled. Although this method can realize the installation of the output flange shaft and bearings, there are still many problems in the actual installation process.

[0005] When the inner diameter of the bearing is greater than 70mm, or the interference fit is large, heating is generally used to expand the inner hole of the bearing before heat-fitting. The bearing is generally heated to 80°C, with a maximum of 100°C. Exceeding 120°C will cause the bearing to temper, resulting in reduced hardness and precision of the bearing rings, affecting the service life of the bearing. It is difficult to achieve precise temperature control through heating spray guns and other equipment, and bearing damage is prone to occur. In addition, this heating method is usually carried out outdoors and in open areas. During the heating process, dust and impurities will adhere to the bearing, which will contaminate the bearing through heating and affect its use effect. Therefore, it is necessary to design a reducer output flange shaft installation device to solve this problem. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a reducer output flange shaft installation device that can clamp and transport the output flange shaft and the bearing, and can evenly heat the bearing inside and outside to make the bearing expand due to the heat, thereby achieving thermal installation of the output flange shaft and the bearing.

[0007] To achieve the above object, the present invention provides the following technical solutions: A reducer output flange shaft mounting device comprises a frame, the frame comprises a transversely arranged mounting platform and a longitudinally arranged mounting column, a transmission component is mounted on one side of the mounting platform, an identification component is mounted on one end of the mounting column close to the transmission component, a cooling component is mounted on the side of the mounting platform away from the transmission component, a clamping component is mounted on the mounting column, and a heating component is mounted on the end of the mounting column away from the clamping component; the clamping component comprises a sliding clamping module, a three-claw chuck is connected to the bottom of the sliding clamping module, the sliding clamping module comprises a mounting plate, and four sets of transverse sliding The four groups of transverse slide blocks are symmetrically arranged in pairs, and their shapes are adapted to the shapes of the transverse slide rails. Two groups of longitudinal slide rails are installed on the side of the mounting plate away from the transverse slide rails, and four groups of longitudinal slide rails are slidably installed on the longitudinal slide rails; the heating component includes a longitudinally arranged heating mounting plate, a heating slide rail installed on the heating mounting plate, a heating slide block slidably connected to the heating slide rail, a telescopic module installed on the heating slide block, an inner heating ring fixedly connected to the telescopic module, and an outer heating ring installed on the top of the mounting platform; the cooling component includes two groups of cooling slide rails fixedly connected to the top of the mounting platform, and an auxiliary slide rail installed on the top of the mounting platform.

[0008] By adopting the above technical scheme, the sliding of the transverse slider on the transverse slide rail can drive the sliding clamping module as a whole to move horizontally relative to the transverse slide rail, and can move from the position of the transmission component to the position of the heating component. When the sliding clamping module moves to the transmission component position, the driving member pushes the fixed plate downward, and the three-claw chuck moves downward and clamps the bearing through the sliding of the longitudinal slider on the longitudinal slide rail. After the clamping is completed, the driving member retracts, driving the longitudinal slider to slide upward on the longitudinal slide rail. The sliding of the transverse slider on the transverse slide rail can drive the sliding clamping module as a whole to move horizontally relative to the transverse slide rail. When the sliding clamping module moves to the heating component position, the driving member pushes the fixed plate downward and moves to a suitable position. The three-claw chuck releases the bearing and heats it through the heating component. Then the above steps are repeated to clamp and transport the output flange shaft. After the transportation is completed, the heated bearing is placed in the heating component. The three-claw chuck drives the output flange shaft to move downward, presses the output flange shaft to the inner hole of the bearing, and completes the thermal installation.

[0009] The present invention is further configured as follows: the mounting platform is horizontally arranged, two groups of mounting columns are installed on the top of the mounting platform, the two groups of mounting columns are arranged at a distance, a mounting bar is installed on the top of the mounting column, two groups of transverse slide rails are installed on the mounting bar, the two groups of transverse slide rails are arranged at a distance at one end, and sliding clamping modules are slidably installed on the two groups of transverse slide rails.

[0010] The present invention is further configured as follows: the identification component has a built-in identification system, the identification system distinguishes between flange shafts and bearings transmitted by the transmission component, and the identification system sends information to the sliding clamping module. If the identification system identifies that the workpiece transmitted by the transmission component is a flange shaft, a signal A is sent to the sliding clamping module; if the identification system identifies that the workpiece transmitted by the transmission component is a bearing, a signal B is sent to the sliding clamping module.

[0011] The present invention is further configured as follows: if the sliding clamping module receives signal A, the sliding clamping module slides toward one end close to the transmission component, and the sliding clamping module is stretched outward as a whole to clamp and transport the bearing; if the sliding clamping module receives signal B, the sliding clamping module slides toward one end close to the transmission component, and the sliding clamping module is tightened inward as a whole to clamp and transport the flange shaft.

[0012] The present invention is further configured as follows: a fixed plate is installed at one end of the longitudinal sliding block away from the longitudinal sliding rail, a driving part is installed on the top of the fixed plate, a three-jaw chuck is connected to the bottom of the fixed plate, the three-jaw chuck includes a chuck main part, three groups of sliding grooves are opened around the chuck main part, and a group of sliding blocks are slidably connected to each group of the sliding grooves.

[0013] The present invention is further configured as follows: the telescopic module includes a mounting block, a telescopic cylinder is installed on the top of the mounting block, one end of the telescopic cylinder is rotatably connected to a telescopic frame, and the telescopic frame is horizontally arranged; the end of the telescopic cylinder away from the mounting block is connected to a fixed block, a fixed strip is installed at the bottom of the fixed block, and the bottom of the fixed strip is connected to an internal heating ring.

[0014] The present invention is further configured as follows: the inner heating ring comprises an inner mounting ring sleeve fixedly connected to the fixing bar, and a heating ring is sleeved inside the inner mounting ring sleeve.

[0015] The present invention is further configured as follows: the external heating ring includes a base plate fixedly connected to the top of the mounting platform, two sets of sleeve rings are installed on the base plate, isolation rings are sleeved inside the sleeve rings, and heating wires are arranged in the interlayer between the base plate and the isolation rings.

[0016] By adopting the above technical solution, after the bearing is transported to the outer heating ring through the clamping assembly, the heating slider slides to a suitable position relative to the heating slide rail, and then the telescopic cylinder extends, pushing the first connecting rod of the telescopic frame to rotate, thereby pushing the telescopic module to extend as a whole, and then driving the inner heating ring to move to the center position of the outer heating ring, and then the heating slider slides downward on the heating slide rail again to make the inner heating ring enter the inner hole of the bearing. At this time, through the cooperation of the inner heating ring and the outer heating ring, it is possible to achieve simultaneous heating of the inside and outside of the bearing.

[0017] By adopting the above technical solution, when the three-jaw chuck needs to transport the bearing, the sliding block slides toward the center of the circle relative to the chuck main part before contacting the bearing, and when the driving part drives the three-jaw chuck to the inner hole of the bearing, the sliding block slides outward until the outer wall of the sliding block fits with the inner wall of the bearing, thereby completing the clamping of the bearing; when the three-jaw chuck needs to transport the flange output shaft, the sliding block slides inward relative to the chuck main part, and the inner wall fits with the outer wall of the flange output shaft, thereby completing the clamping of the flange output shaft.

[0018] The present invention is further configured as follows: a sliding disk is slidably connected to the two groups of cooling slide rails, an auxiliary slider is installed at one end of the cooling slide rail, the auxiliary slider is slidably connected to the auxiliary slide rail, and a cooling module is installed on the top of the sliding disk.

[0019] The present invention is further configured as follows: the cooling module comprises two groups of outer mounting rings, the outer side buckles of the two groups of outer mounting rings are connected with fixed buckles, the inner side sleeve of the outer mounting ring is provided with an inner mounting ring, the outer mounting ring is provided with an outer cooling pipe in the sandwich layer between the inner mounting ring, and the inner wall sleeve of the inner mounting ring is provided with an inner cooling pipe.

[0020] By adopting the above technical solution, after the bearing and the output flange shaft are installed, the installed whole is transported through the clamping assembly. After the cooling module slides to the side close to the clamping assembly, the clamping assembly transports the installed whole to the inside of the cooling module. Then, the cooling module slides to the end away from the clamping assembly to avoid being affected by the temperature of the heating assembly and to avoid a decrease in cooling efficiency. The inner cooling pipe and the outer cooling pipe cool down the installed whole, and the setting of the two groups of cooling pipes can further accelerate the cooling speed. When the inner cooling pipe becomes hot due to the heat exchange of the installed whole, the outer cooling pipe can cool down the inner cooling pipe, thereby achieving rapid cooling.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the sliding clamping module moves to the transmission component position through the sliding of the transverse slider on the transverse slide rail, the three-jaw chuck moves downward and clamps the bearing through the sliding of the longitudinal slider on the longitudinal slide rail. After clamping, the driving part retracts, and the sliding of the transverse slider on the transverse slide rail can drive the sliding clamping module to move horizontally relative to the transverse slide rail as a whole. When the sliding clamping module moves to the heating component position, the driving part pushes the fixed plate downward to move to the appropriate position, and the three-jaw chuck releases the bearing and heats it through the heating component. Then repeat the above steps to clamp and transport the output flange shaft. After transportation is completed, the heated bearing is placed in the heating component. The three-jaw chuck drives the output flange shaft to move downward, presses the output flange shaft to the inner hole of the bearing, and completes the thermal installation.

[0022] 2. When the three-jaw chuck needs to transport the bearing, before contacting the bearing, the sliding block slides toward the center of the circle relative to the chuck main part. After the driving part drives the three-jaw chuck to the inner hole of the bearing, the sliding block slides outward until the outer wall of the sliding block fits with the inner wall of the bearing, thereby completing the clamping of the bearing; when the three-jaw chuck needs to transport the flange output shaft, the sliding block slides inward relative to the chuck main part, and the inner wall fits with the outer wall of the flange output shaft, thereby completing the clamping of the flange output shaft.

[0023] 3. After the bearing is transported to the outer heating ring through the clamping assembly, the heating slider slides to the appropriate position relative to the heating slide rail, and then the telescopic cylinder extends, pushing the first connecting rod of the telescopic frame to rotate, thereby pushing the telescopic module to extend as a whole, and then driving the inner heating ring to move to the center position of the outer heating ring, and then the heating slider slides downward on the heating slide rail again to make the inner heating ring enter the inner hole of the bearing. At this time, through the cooperation of the inner heating ring and the outer heating ring, the inner and outer sides of the bearing can be heated simultaneously.

[0024] 4. After the bearing and the output flange shaft are installed, the clamping assembly drives the installed whole to be transported. After the cooling module slides to the side close to the clamping assembly, the clamping assembly transports the installed whole to the inside of the cooling module. Then, the cooling module slides to the end away from the clamping assembly to avoid being affected by the temperature of the heating assembly and to avoid a decrease in cooling efficiency. The inner cooling pipe and the outer cooling pipe cool down the installed whole, and the setting of the two sets of cooling pipes can further accelerate the cooling speed. When the inner cooling pipe becomes hot due to the heat exchange of the installed whole, the outer cooling pipe can cool down the inner cooling pipe, thereby achieving rapid cooling.

DETAILED DESCRIPTION

[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0038] See also Figure 1-10 , the present invention provides the following technical solutions: For example, see Figure 1-10A device for installing a reducer output flange shaft includes a frame 1. The frame 1 provides an installation environment for the entire device to ensure the stable operation of the entire device. The frame 1 includes a horizontally arranged mounting platform 11 and a longitudinally arranged mounting column 12. A conveying component 2 is installed on one side of the mounting platform 11, and the conveying component 2 can transport the output flange shaft and the bearing. An identification component 6 is installed on the end of the mounting platform 11 close to the conveying component 2. The identification component 6 has a built-in identification system to send information to the clamping component 3. A cooling component 5 is installed on the side of the mounting platform 11 away from the conveying component 2. The cooling component 5 can cool down the installed output flange shaft and bearing. A clamping component 3 is installed on the mounting column 12. The clamping component 3 can clamp and transport the output flange shaft and bearing transported by the conveying component 2 to the heating component 4 for installation. A heating component 4 is installed on the end of the mounting column 12 away from the clamping component 3. The heating component 4 can expand the inner hole of the bearing by heating for heat sleeve.

[0039] See also Figure 1 The mounting platform 11 is arranged horizontally, and two groups of mounting columns 12 are installed on the top of the mounting platform 11. The mounting platform 11 provides an installation environment for the mounting columns 12, and the two groups of mounting columns 12 are arranged at a distance. A mounting bar 31 is installed on the top of the mounting column 12, and the mounting bar 31 is arranged horizontally. Two groups of transverse slide rails 32 are installed on the mounting bar 31, and the two groups of transverse slide rails 32 are arranged at a distance from one end. Sliding clamping modules 33 are slidably installed on the two groups of transverse slide rails 32, and the sliding clamping modules 33 can slide horizontally relative to the transverse slide rails 32.

[0040] See also Figure 2 , Figure 3 The bottom of the sliding clamping module 33 is connected with a three-claw chuck 34, which can clamp the flange output shaft inward and open the bearing outward. The sliding clamping module 33 includes a mounting plate 331. Four groups of transverse sliders 332 are installed at one end of the mounting plate 331 close to the mounting bar 31. The mounting plate 331 provides an installation environment for the transverse sliders 332. The four groups of transverse sliders 332 are symmetrically arranged in pairs, and their shapes are adapted to the shape of the transverse slide rails 32. The four groups of transverse sliders 332 can slide horizontally on the transverse slide rails 32. Two groups of longitudinal slide rails 333 are installed on the side of the mounting plate 331 away from the transverse sliders 332. Four groups of longitudinal sliders 335 are slidably installed on the longitudinal slide rails 333. The four groups of longitudinal sliders 335 can slide vertically on the longitudinal slide rails 333. A fixing plate 334 is installed at one end of the longitudinal slider 335 away from the longitudinal slide rails 333, and a driving member 336 is installed on the top of the fixing plate 334.

[0041] Specifically, by sliding the transverse slider 332 on the transverse slide rail 32, the sliding clamping module 33 can be driven to move horizontally relative to the transverse slide rail 32 as a whole, and can move from the position of the conveying component 2 to the position of the heating component 4. When the sliding clamping module 33 moves to the position of the conveying component 2, the driving member 336 pushes the fixing plate 334 downward, and the longitudinal slider 335 slides downward on the longitudinal slide rail 333, so that the three-claw chuck 34 moves downward and clamps the bearing. After clamping is completed, the driving member 336 retracts, driving the longitudinal slider 335 to slide upward on the longitudinal slide rail 333, and the longitudinal slider 335 is driven to slide upward on the longitudinal slide rail 333. The sliding of the slider 332 on the transverse slide rail 32 can drive the sliding clamping module 33 to move horizontally relative to the transverse slide rail 32 as a whole. When the sliding clamping module 33 moves to the position of the heating component 4, the driving member 336 pushes the fixed plate 334 downward and moves to a suitable position. The three-jaw chuck 34 releases the bearing and heats it through the heating component 4. Then, the above steps are repeated to clamp and transport the output flange shaft. After transportation is completed, it is placed above the heating component 4. At this time, the heated bearing is placed in the heating component 4. The three-jaw chuck 34 drives the output flange shaft to move downward and presses the output flange shaft to the inner hole of the bearing to complete the thermal installation.

[0042] See also Figure 4 The identification component 6 distinguishes the flange shaft and bearing transmitted by the transmission component 2 through its built-in identification system. The identification system sends information to the sliding clamping module 33. If the identification system identifies that the workpiece transmitted by the transmission component 2 is a flange shaft, a signal A is sent to the sliding clamping module 33; if the identification system identifies that the workpiece transmitted by the transmission component 2 is a bearing, a signal B is sent to the sliding clamping module 33, wherein the signal A and the signal B are sent alternately. If the identification system sends the signal A twice and the signal B twice in succession, the entire equipment stops running, indicating that an abnormal situation has occurred and requires special processing.

[0043] Among them, sending signal A once and sending signal B once is a group, and the time interval of a group is set to a certain time, which is determined according to the installation time and cooling time required for the flange shaft and the bearing. In actual use, the time interval of a group is usually set to be slightly longer than the installation time of the flange shaft and the bearing to avoid conflicts.

[0044] If the sliding clamping module 33 receives the signal A, the sliding clamping module 33 slides toward one end of the conveying assembly 2, and the sliding clamping module 33 is first tightened inward until it extends into the bearing, and the sliding clamping module 33 is stretched outward as a whole, and slides outward through the sliding block 343 until the outer walls of the three sets of sliding blocks 343 fit the inner wall of the bearing, thereby clamping and transporting the bearing; If the sliding clamping module 33 receives signal B, the sliding clamping module 33 slides toward one end of the conveying component 2, and the sliding clamping module 33 is tightened inward as a whole, and slides inward through the sliding block 343 until the arc-shaped inner wall of the sliding block 343 is in contact with the flange shaft, thereby clamping the flange shaft for transportation.

[0045] See also Figure 4 The bottom of the fixed plate 334 is connected with a three-claw chuck 34, which can clamp the bearing and the output flange shaft. The three-claw chuck 34 includes a chuck main part 341, and a matching hole 344 is provided at the center of the chuck main part 341. The matching hole 344 is adapted to the shape of the flange shaft, so that the flange shaft can be plugged into the inside of the chuck main part 341, and the overall stability of the flange shaft can be ensured during the clamping and moving process of the flange shaft. Three groups of slide grooves 342 are provided around the chuck main part 341, and each group of slide grooves 342 is slidably connected with a group of sliding blocks 343, which are adapted to the shape of the slide grooves 342, and the sliding blocks 343 can slide in the slide grooves 342. The sliding blocks 343 are arranged in an arc shape near one end of the chuck main part 341, and their shape is adapted to the flange shaft, so that the flange shaft can be accurately clamped to prevent it from slipping.

[0046] Specifically, when the three-jaw chuck 34 needs to transport the bearing, before contacting the bearing, the sliding block 343 slides toward the center of the circle relative to the chuck main part 341, and when the driving part 336 drives the three-jaw chuck 34 to the inner hole of the bearing, the sliding block 343 slides outward until the outer wall of the sliding block 343 fits with the inner wall of the bearing, thereby completing the clamping of the bearing; when the three-jaw chuck 34 needs to transport the flange output shaft, the sliding block 343 slides inward relative to the chuck main part 341, and the inner wall fits with the outer wall of the flange output shaft, thereby completing the clamping of the flange output shaft.

[0047] For example 2, please refer to Figure 5-Figure 8 , this embodiment 2 makes the following improvements on the basis of embodiment 1. Specifically, although embodiment 1 can realize the clamping, transportation and installation of bearings and output flange shafts, during the actual installation process, when the heating component 4 heats the bearing, if only external heating is used, the temperature difference between the outside and inside of the heating component 4 is too large. When the outside is heated to an overheating temperature, the inside can reach the required temperature, which can easily cause the bearing to temper, resulting in reduced hardness and precision of the bearing ring, affecting the service life of the bearing. Therefore, it is necessary to set a heating component 4 that can heat the outer wall of the bearing while uniformly heating the entire bearing to avoid excessive local temperature of the bearing.

[0048] See also Figure 5 , Figure 6The heating assembly 4 includes a longitudinally arranged heating mounting plate 41, on which a heating slide rail 42 is mounted, the heating slide rail 42 is arranged in a vertical direction, a heating slider 43 is slidably connected to the heating slide rail 42, the heating slider 43 can achieve vertical displacement relative to the heating slide rail 42, a telescopic module 44 is installed at one end of the heating slider 43 away from the heating slide rail 42, the telescopic module 44 can be telescoped in the horizontal direction, and an inner heating ring 45 is fixedly connected at one end of the telescopic module 44 away from the heating slide rail 42, and the inner heating ring 45 can be driven to move in the horizontal direction through the telescopic module 44.

[0049] See also Figure 5 , Figure 6 The telescopic module 44 includes a mounting block 441, a telescopic cylinder 442 is installed on the top of the mounting block 441, and the mounting block 441 provides an installation environment for the telescopic cylinder 442. The telescopic cylinder 442 is rotatably installed on the top of the mounting block 441, and the telescopic cylinder 442 can achieve a small range of rotation on the top of the mounting block 441. One end of the telescopic cylinder 442 is rotatably connected to a telescopic frame 443, and the telescopic frame 443 is composed of a plurality of groups of hinged connecting rods. When the telescopic cylinder 442 is extended, the first hinged connecting rod is pushed, so that the angles of the plurality of groups of hinged connecting rods are adjusted, thereby achieving the extension of the telescopic frame 443. The end of the telescopic cylinder 442 away from the mounting block 441 is connected to a fixed block 444, and a fixed bar 445 is installed at the bottom of the fixed block 444. The fixed block 444 provides an installation environment for the fixed bar 445, and the bottom of the fixed bar 445 is connected to an inner heating ring 45. The inner heating ring 45 comprises an inner mounting ring sleeve 451 fixedly connected to the fixing bar 445 , and a heating ring 452 is sleeved inside the inner mounting ring sleeve 451 . The heating ring 452 can be electrically heated and can be controlled to be heated to a certain temperature.

[0050] See also Figure 7 The outer heating ring 46 includes a base plate 463 fixedly connected to the top of the mounting platform 11, and two groups of rings 461 are installed on the base plate 463. The two groups of rings 461 are arranged in a vertical direction. An isolation ring 464 is sleeved inside the ring 461. The isolation ring 464 prevents the heating wire 462 from directly contacting the bearing, and prevents impurities, dust, and lubricating oil on the bearing from sticking to the heating wire 462. A heating wire 462 is arranged in the interlayer between the base plate 463 and the isolation ring 464. The heating wire 462 can be electrically heated and can be controlled to be heated to a certain temperature.

[0051] Specifically, after the bearing is transported to the outer heating ring 46 through the clamping assembly 3, the heating slider 43 slides to a suitable position relative to the heating slide rail 42, and then the telescopic cylinder 442 extends, pushing the first connecting rod of the telescopic frame 443 to rotate, thereby pushing the telescopic module 44 to extend as a whole, and then driving the inner heating ring 45 to move to the center position of the outer heating ring 46, and then the heating slider 43 slides downward on the heating slide rail 42 again, so that the inner heating ring 45 enters the inner hole of the bearing. At this time, through the cooperation of the inner heating ring 45 and the outer heating ring 46, it is possible to achieve simultaneous heating of the inside and outside of the bearing.

[0052] Specifically, since the general temperature of bearing heating is 80°C-100°C. When the inner diameter of the bearing is greater than 70mm, or the interference fit is large, the inner hole of the bearing is generally expanded by heating before heat-fitting. The bearing is generally heated to 80°C, with a maximum of 100°C. Exceeding 120°C will cause the bearing to temper, resulting in reduced hardness and precision of the bearing ring, affecting the service life of the bearing, so the inner heating ring 45 and the outer heating ring 46 are both electric heating rings, which can accurately control the heating temperature to avoid affecting their service life due to overheating.

[0053] For example 3, please refer to Figure 9-10 , this embodiment three makes the following improvements on the basis of embodiment one and embodiment two. Specifically, although the transportation and installation of the output flange shaft and the bearing can be realized through embodiment one and embodiment two, in the actual installation process, after the output flange shaft and the bearing are installed, it is necessary to transfer the installed output flange shaft and the bearing as a whole, and the temperature thereof is maintained at about 100°C. If the output flange shaft and the bearing are transported without cooling, it is easy to cause injuries to the staff, so it is necessary to set a mechanism that can cool them to solve the above problem.

[0054] See also Fig. 9 The cooling assembly 5 includes two groups of cooling rails 51 fixedly connected to the top of the mounting platform 11, and sliding plates 52 are slidably connected to the two groups of cooling rails 51. The sliding plates 52 can slide relative to the two groups of cooling rails 51. An auxiliary slider 53 is installed at one end of the cooling rail 51. The auxiliary slider 53 is slidably connected to the auxiliary rail 54. The auxiliary slider 53 slides on the auxiliary rail 54, which can drive the sliding plate 52 to slide on the two groups of cooling rails 51. A cooling module 55 is installed on the top of the sliding plate 52.

[0055] See also Fig.10The cooling module 55 includes two groups of outer mounting rings 551. The outer sides of the two groups of outer mounting rings 551 are connected with fixing buckles 552. The fixing buckles 552 ensure that the two groups of outer mounting rings 551 are stably connected and do not fall off. An inner mounting ring 553 is sleeved on the inner side of the outer mounting ring 551. An outer cooling pipe 555 is arranged in the interlayer between the outer mounting ring 551 and the inner mounting ring 553. An inner cooling pipe 554 is sleeved on the inner wall of the inner mounting ring 553.

[0056] Specifically, after the bearing and the output flange shaft are installed, the clamping assembly 3 drives the installed whole to be transported. After the cooling module 55 slides to the side close to the clamping assembly 3, the clamping assembly 3 transports the installed whole to the inside of the cooling module 55. Subsequently, the cooling module 55 slides to the end away from the clamping assembly 3 to avoid being affected by the temperature of the heating assembly 4 and to avoid a decrease in cooling efficiency.

[0057] Specifically, the inner cooling tube 554 and the outer cooling tube 555 cool down the entire installed body, and the setting of the two groups of cooling tubes can further accelerate the cooling speed. When the inner cooling tube 554 becomes hot due to the overall heat exchange of the installed body, the outer cooling tube 555 can cool down the inner cooling tube 554, thereby achieving rapid cooling.

[0058] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
