Description

Technical Field

[0001] The utility model relates to a base bushing heating device, in particular to a rotary base bushing heating device. Background Art

[0002] Laser printers are currently widely used in people's daily work. In a laser printer, a laser motor needs to assemble an optical axis and a boss base bushing. The traditional method is cold press fitting. The optical axis is clamped by a pressing cylinder and pressed into the boss base bushing 1a. Although this operation can assemble the optical axis into the boss base bushing 1a, it is likely to cause a deviation in the perpendicularity of the optical axis. For a laser motor with a speed of more than 50,000 revolutions per minute, this deviation will cause shaking and jumping during high-speed rotation, affecting the use effect.

[0003] Currently, thermal assembly is also adopted. For example, in the existing patent No. "201821652418.0" with the patent name "A thermal assembly system for a wind blade and a shaft core", it is recorded that "by heating the assembly hole in the middle of the wind blade, the assembly hole is temporarily enlarged. At this time, the wind blade and the shaft core are assembled. After cooling, the assembly hole shrinks, and the assembly of the wind blade and the shaft core is completed. This assembly method depends on the tolerance of the parts themselves, does not generate a torque weakness point on the shaft core, can also avoid the D-cut flat position affecting the coaxiality of the shaft core, and also avoids the risks of flying points and false soldering caused by welding, reduces the production steps and costs, and improves the service life after the assembly of the wind blade and the shaft core". Therefore, the thermal assembly method of this patent can be used for reference to assemble the optical axis and the boss base bushing 1a. However, it has low working efficiency and low automation. Because it requires manual placement of the shaft core into the shaft core fixing hole of the beer machine fixture, and after the wind blade is installed on the shaft core, it is necessary to wait for the wind blade to cool completely before the wind blade installed on the shaft core can be transferred away. During the cooling process, the system cannot be used for subsequent assembly and processing of the wind blade and the shaft core. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a rotary base bushing heating device with a base bushing heating and an automatic cooling station for the base bushing after assembly, so that the utility model can continuously assemble, solving the defect that it is currently necessary to stop the machine and wait for cooling before operating again.

[0005] The technical solution adopted by the utility model is as follows: The utility model includes a turntable driver and a rotating disk connected to the turntable driver. At least four bushing carriers are annularly arranged on the rotating disk. An upper bushing feeding station, a bushing heating and assembling station, a bushing cooling station, and a bushing discharging station are sequentially arranged on the rotating disk. The bushing heating and assembling station includes a temperature detector, a heater, a heating coil connected to the heater, and a lifting mechanism. The lifting mechanism is arranged below the rotating disk and is used to lift the bushing carrier to contact the heating coil. The temperature detector is used to detect the heating temperature of the base bushing in the bushing carrier. After heating to the set temperature, the shaft core is assembled into the base bushing manually or by a shaft core feeding manipulator. The bushing cooling station is used to cool the base bushing after heating and assembling the shaft core, and the discharging station is used to take out and discharge the cooled base bushing.

[0006] Further, the bushing carrier includes a carrier rod sleeve, a lifting rod, a carrier seat, a bushing carrier column, and a fixing seat. The fixing seat is fixedly installed on the rotating disk. The carrier seat is arranged at the upper end of the fixing seat, is arranged at the lower end of the rotating disk and passes through the rotating disk to be connected with the fixing seat. The lower end of the lifting rod is sleeved and passes through the carrier rod sleeve. The upper end of the lifting rod passes through the rotating disk and the fixing seat and is then connected with the carrier seat. The bushing carrier column is installed at the upper end of the carrier seat. The bushing carrier column is provided with a bushing hole adapted to the base bushing. A sliding groove and a limiting slide bar are arranged at the lower part of the lifting rod. Limiting holes adapted to the limiting slide bar are arranged at both ends of the carrier rod sleeve. The limiting slide bar is fixed between the two limiting holes and crosses the sliding groove. A first spring sleeved on the lifting rod is arranged in the carrier rod sleeve. The first spring is located between the limiting slide bar and the rotating disk. The sliding groove is used to limit the rising height of the lifting mechanism driving the lifting rod.

[0007] Further, the bushing cooling station includes a water chiller and a plurality of water-cooled blowing pipes connected to the water chiller. Each water-cooled blowing pipe faces the bushing carrier after passing through the bushing heating and assembling station. The bushing cooling station is used to cool the base bushing after heating and assembling the shaft core through a plurality of water-cooled blowing pipes.

[0008] Further, the rotary base bushing heating device further includes an MCU controller. The turntable driver, the temperature detector, the heater, the lifting mechanism, and the water chiller are all electrically connected to the MCU controller.

[0009] Further, the lifting mechanism includes a lifting cylinder and a lifting column connected to the lifting cylinder. The lifting column is directly below the lifting rod at the bushing heating and assembling station. The lifting column is used to lift the bushing carrier column at the bushing heating and assembling station to contact the heating coil.

[0010] Further, a heat dissipation ceramic bushing sleeve sleeving on the bushing carrier column is also arranged at the upper end of the vehicle seat.

[0011] Further, the depth height of the bushing hole is consistent with the length of the shaft core extending after being inserted into the base bushing.

[0012] The beneficial effects of the utility model are as follows: 1. The rotating disk is driven to rotate by the turntable driver, so that the bushing carrier can be continuously driven into the bushing heating and assembling station. Then, the bushing carrier at the bushing heating and assembling station is lifted into the heating coil by the lifting mechanism for heating. At the same time, a temperature detector is equipped to check the heating temperature of the base bushing in the bushing carrier, so as to ensure the expansion degree of the inner hole of the base bushing installation through the temperature, so that the shaft core can be smoothly inserted into the base bushing; 2. The bushing cooling station can quickly cool the base bushing with the shaft core heated and assembled, so that the base bushing can be smoothly cooled and shrunk to hold the shaft core tightly, and then the base bushing with the shaft core assembled can be quickly unloaded, effectively improving the production efficiency.

[0019] Such as Figures 1 to 6As shown, in this embodiment, the utility model includes a turntable driver 1 and a rotating disk 2 connected to the turntable driver 1. At least four bushing carriers 3 are annularly arranged on the rotating disk 2. An upper bushing feeding station 4, a bushing heating and assembling station 5, a bushing cooling station 6, and a bushing discharging station 7 are sequentially arranged on the rotating disk 2. The bushing heating and assembling station 5 includes a temperature detector 51, a heater 52, a support stand 53, a heating coil 54 connected to the heater 52, and a jacking mechanism 55. The temperature detector 51 is obliquely fixed on the support stand 53. The jacking mechanism 55 is arranged below the rotating disk 2 and is used to jack up the bushing carrier 3 to contact the heating coil 54. The temperature detector 51 is used to detect the heating temperature of the base bushing 1a in the bushing carrier 3. After heating to the set temperature, the shaft core is assembled into the base bushing 1a manually or by a shaft core feeding manipulator. The bushing cooling station 6 is used to cool the base bushing 1a after heating and assembling the shaft core. The discharging station is used to take out and discharge the cooled base bushing 1a. If manual feeding is adopted, a descending driver and a guide pipe connected to the descending driver can be used. This design can drive the guide pipe to be placed at the upper end of the base bushing 1a when heated to the set temperature, and the shaft core can be dropped into the base bushing 1a by manually putting the shaft core into the guide pipe. If a simpler method is adopted, a clamping tool can be directly used to clamp the shaft core and put it into the base bushing 1a. If a shaft core feeding manipulator is adopted, the shaft core can be directly clamped by the shaft core feeding manipulator and then placed into the base bushing 1a.

[0020] In this embodiment, the bushing carrier 3 includes a carrier rod sleeve 31, a jacking rod 32, a carrier base 33, a bushing carrier column 34, and a fixing base 35. The bushing carrier column 34 is made of a material with high thermal conductivity. The fixing base 35 is fixedly installed on the rotating disk 2. The carrier base 33 is arranged at the upper end of the fixing base 35. The carrier rod sleeve 31 is arranged at the lower end of the rotating disk 2 and passes through the rotating disk 2 to be connected with the fixing base 35. The lower end of the jacking rod 32 is sleeved and passes through the carrier rod sleeve 31. The upper end of the jacking rod 32 passes through the rotating disk 2 and is connected with the carrier base 33 after passing through the fixing base 35. The bushing carrier column 34 is installed at the upper end of the carrier base 33. The bushing carrier column 34 is provided with a bushing hole 341 adapted to the base bushing 1a. The lower part of the jacking rod 32 is provided with a sliding groove 342 and a limiting slide rod 343. Both ends of the carrier rod sleeve 31 are provided with limiting holes 331 adapted to the limiting slide rod 343. The limiting slide rod 343 is fixed between the two limiting holes 331 and horizontally penetrates the sliding groove 342. A first spring 36 sleeved on the jacking rod 32 is arranged in the carrier rod sleeve 31. The first spring 36 is located between the limiting slide rod 343 and the rotating disk 2. This design drives the jacking rod 32 to rise through the jacking mechanism 55, thereby driving the bushing carrier column 34 on the carrier base 33 to rise, so that the base bushing 1a in the bushing carrier column 34 contacts the heating coil 54. When the jacking rod 32 rises, the sliding groove 342 moves upward in the limiting slide rod 343. At the same time, the sliding groove 342 can limit the rising height of the jacking mechanism 55 driving the jacking rod 32, ensuring that the base bushing 1a contacts the heating coil 54.

[0021] In this embodiment, a heat dissipation ceramic column sleeve 37 sleeved on the bushing carrier column 34 is further arranged at the upper end of the carrier base 33. The bushing cooling station 6 includes a water chiller and a plurality of water cooling air pipes connected to the water chiller. Each water cooling air pipe is directed at the bushing carrier 3 after passing through the bushing heating and assembly station 5. The bushing cooling station 6 is used to cool the base bushing 1a after heating and assembling the shaft core through a plurality of water cooling air pipes. The bushing carrier 3 after passing through the bushing heating and assembly station 5 can be cooled by a plurality of water cooling air pipes. At the same time, with the cooperation of the heat dissipation ceramic column sleeve 37, the temperature can be reduced more quickly, so as to ensure that the base bushing 1a can be quickly cooled, enabling it to shrink and hold the shaft core tightly, completing the entire assembly process.

[0022] In this embodiment, the rotary base bushing heating device further includes an MCU controller. The rotary disk driver 1, the temperature detector 51, the heater 52, the jacking mechanism 55, and the water chiller are all electrically connected to the MCU controller.

[0023] In this embodiment, the jacking mechanism 55 includes a jacking cylinder 551 and a jacking column 552 connected to the jacking cylinder 551. The jacking column 552 is located directly below the jacking rod 32 at the bushing heating and assembling station 5. The jacking column 552 is used to jack up the bushing carrier column 34 at the lifting bushing heating and assembling station 5 to contact the heating coil 54.

[0024] In this embodiment, the hole depth of the bushing hole 341 is the same as the length of the shaft core extending after being inserted into the base bushing 1a, so as to ensure the insertion depth of the shaft core into the base bushing 1a.

[0025] In this embodiment, the working process of the present utility model is as follows: Manually load the base bushing 1a into the bushing carrier 3 through the bushing loading station 4 or with the help of a loading manipulator. Then, drive the rotating disk 2 to rotate through the turntable driver 1, so as to drive the bushing carrier 3 equipped with the base bushing 1a to transfer to the bushing heating and assembling station 5. Then, the jacking mechanism 55 drives the base bushing 1a in the bushing carrier 3 to jack up to the heating coil 54. Then, when the temperature detector 51 detects that the base bushing 1a in the bushing carrier 3 is heated to the set temperature, it proves that the inner hole of the installed base bushing 1a expands to the required assembly spacing. Then, manually or with the shaft core loading manipulator, assemble the shaft core into the base bushing 1a. Then, the jacking mechanism 55 resets, and cool the base bushing 1a through the bushing cooling station 6, so that the inner hole of the installed base bushing 1a shrinks and tightly holds the shaft core. Finally, take out and unload the cooled base bushing 1a through the unloading station. Thus, the present utility model can continuously heat and assemble new base bushings 1a while cooling, loading, and unloading, effectively improving the production efficiency of the equipment and the utilization rate of the heat generated by the heating coil 54.

[0026] The present utility model is applied to the technical field of laser printer processing equipment.

[0027] Although the embodiments of the present utility model are described with actual solutions, they do not constitute a limitation to the meaning of the present utility model. For those skilled in the art, it is obvious to modify its implementation solutions according to this specification and combine them with other solutions.
