Description

Technical Field

[0001] This utility model belongs to the field of mechanical design technology, and in particular relates to a roller assembly quality testing platform. Background Technology

[0002] In bar and wire rod production lines, with increasingly stringent requirements for product surface quality, numerous rollers are installed on the rolling channel to prevent scratches on the rolled parts. However, during roller assembly, sometimes the bearing quality standards are not high, or excessive lubrication in the bearing housing leads to high internal pressure in the roller, or the cold weather causes thick grease, resulting in resistance and inflexible rotation of the roller. All of these factors can affect the normal operation of the roller, and it is difficult to detect inflexible roller rotation online. Therefore, it is necessary to test the rollers before they are put into operation to ensure that the rollers rotate flexibly.

[0003] In the existing technology, there is no dedicated testing platform for roller assembly quality, making it impossible to effectively test the rotational flexibility of rollers before they are put into operation. This results in some rollers with inflexible rotation being installed on the production line, affecting product quality and production efficiency.

[0004] To address these issues, we propose a roller assembly quality testing platform. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-6 A roller assembly quality testing platform includes a housing 1. A pusher 2 is installed at the bottom of the housing 1. Two pusher supports 3 are movably hinged to the telescopic end of the pusher 2. A roller mounting platform 4 is fixedly connected to the upper surface of each pusher support 3. The two roller mounting platforms 4 are slidably connected inside the housing 1. Four wheels 5 are fixedly connected to the outer surface of each roller mounting platform 4. Each wheel 5 is slidably connected to the inside of the housing 1. A roller base 6 is fixedly connected to the upper surface of each roller mounting platform 4. A through hole 7 is opened on the front of each roller base 6. A threaded hole 8 is opened on one side of each roller base 6. The two through holes 7 are connected to the threaded holes 8. A roller fixing shaft 9 is locked inside the two through holes 7. A test roller 10 is fixedly connected to the outer surface of each roller fixing shaft 9. The roller fixing shaft 9 is provided with positioning holes 11 inside. The two threaded holes 8 are threaded with threaded rods 12 inside. One end of each threaded rod 12 passes through the positioning hole 11 and extends into the roller base 6. The end of each threaded rod 12 away from the threaded hole 8 is fixedly connected to a worm gear 13. The outer surface of each worm gear 13 is meshed with a worm 14. One end of each worm 14 is fixedly connected to a knob 15 for easy manual adjustment and to reduce labor intensity. The inner wall of the housing 1 is fixedly connected to two sliding grooves 36. The outer surfaces of the two worms 14 and the two threaded rods 12 are rotatably connected to fixed seats 37. The two fixed seats 37 are slidably connected inside the two sliding grooves 36, which can counteract the radial force generated when the threaded rods 12 rotate, improve transmission stability, and prevent the threaded rods 12 from deviating.

[0026] Each roller mounting platform 4 has a fixed grease collection box 16 on its upper surface. Each grease collection box 16 contains a metal filter screen 17 and oil-absorbing cotton 18. The grease collection box 16 collects waste oil generated during testing, preventing environmental pollution and facilitating subsequent waste oil treatment. The metal filter screen 17 filters impurities from the waste oil, preventing them from clogging the oil-absorbing cotton 18 and improving its absorption efficiency. The oil-absorbing cotton 18 absorbs the waste oil, reducing its flow and preventing it from spreading, further improving the collection effect.

[0027] Telescopic rods 19 are fixedly connected to the sides of the two roller mounting platforms 4 that are close to each other. The telescopic end of each telescopic rod 19 is fixedly connected to the inner wall of the housing 1. A compression spring 20 is sleeved on the outer surface of each telescopic rod 19. The ends of the two compression springs 20 that are far from each other are fixedly connected to the sides of the two roller mounting platforms 4 that are close to each other. The ends of the two compression springs 20 that are close to each other are fixedly connected to the inner wall of the housing 1. The telescopic rods 19 can provide guidance for the movement of the roller mounting platforms 4, ensuring that the roller mounting platforms 4 remain stable during movement and preventing the roller mounting platforms 4 from shifting. The compression springs 20 can provide cushioning for the roller mounting platforms 4, reducing the impact force on the roller mounting platforms 4 during movement, thereby protecting the roller mounting platforms 4 and the components on them and extending their service life. When the pusher 2 stops working, the compression springs 20 rely on their own characteristics to pull the test roller 10 tightly against the rubber friction wheel 22, ensuring the fit between the two.

[0028] A motor 21 is fixedly connected to the upper surface of the housing 1. A rubber friction wheel 22 is fixedly connected to the output end of the motor 21. A polyurethane wear-resistant coating 23 is fixedly connected to the outer surface of the rubber friction wheel 22. The rubber friction wheel 22 has good elasticity and wear resistance, and can make close contact with the test roller 10, thereby ensuring effective power transmission. The polyurethane wear-resistant coating 23 has good wear resistance and corrosion resistance, which can extend the service life of the rubber friction wheel 22 and reduce maintenance costs.

[0029] A support frame 24 is fixedly connected to the right side of the housing 1. An electrical control box 25 is fixedly connected to the upper surface of the support frame 24. A control switch 26, a frequency converter 27, a time relay 28, and an emergency stop button 29 are fixedly installed on the front of the electrical control box 25. The electrical control box 25 is the control center of the test platform. It integrates various electronic components and can control the start, stop, and speed of the motor 21, thereby realizing the control of the test process.

[0030] Control switch 26 is the start and stop switch of the test platform. It can control the power supply and power cut-off of motor 21, thereby controlling the start and end of the test process. Inverter 27 is an electronic device used to adjust the speed of motor 21. It can adjust the speed of motor 21 by changing the power supply frequency of motor 21, thereby meeting the needs of different test conditions. Time relay 28 is an electronic component that can control the circuit on and off according to time. It can set the test time. When the test time reaches the set value, it automatically cuts off the power supply of motor 21 and stops the test process. Emergency stop button 29 is an emergency stop switch. When an abnormal situation occurs during the test, pressing emergency stop button 29 can immediately cut off the power supply of motor 21 and stop the test process, thereby avoiding accidents.

[0031] Two hinge blocks 30 are fixedly connected to the upper surface of one of the roller mounting platforms 4. The inner walls of the two hinge blocks 30 are movably hinged to a safety pin 31. A pressure sensor 32 is fixedly connected to the upper surface of the other roller mounting platform 4. The bottom surface of the safety pin 31 contacts the upper surface of the pressure sensor 32. The safety pin 31 is a safety device that can restrict the movement of the roller mounting platform 4 during the test to prevent accidental movement of the roller mounting platform 4, thereby ensuring the safety of the test process. The pressure sensor 32 is an electronic component that can detect pressure. It can detect the pressure applied to it by the safety pin 31. When the pressure exceeds the set value, the pressure sensor 32 will send a signal to the electrical control box 25, and the electrical control box 25 will control the motor 21 to stop rotating, thereby preventing accidents from occurring.

[0032] A protective cover 33 is hinged to the upper surface of the housing 1. A safety hook 34 is fixedly connected to the outer surface of the protective cover 33, and a cover travel limiter 35 is fixedly connected to the inner wall of the housing 1. The protective cover 33 protects the operator from potential hazards during testing, such as high-speed rotating parts and splashing waste oil. The safety hook 34 secures the protective cover 33 to the housing 1, ensuring stable installation. The cover travel limiter 35 restricts the range of movement of the protective cover 33, preventing excessive movement and thus protecting the connecting parts between the protective cover 33 and the housing 1.

[0033] The working principle of this utility model is as follows: When in use, first turn on the power of the electrical control box 25, press the pusher 2 button, the pusher 2 rises, then open the protective cover 33, lower the safety pin 31, put the test roller 10 to be tested on the outer surface of the roller fixing shaft 9, and then fix the roller fixing shaft 9 inside the through hole 7 on the roller base 6. Rotate the knob 15 to drive the worm 14 to rotate. The rotation of the worm 14 will drive the worm wheel 13 to rotate. The rotation of the worm wheel 13 will drive the threaded rod 12 to rotate inside the threaded hole 8. Since the diameter of the threaded hole 8 corresponds to the diameter of the positioning hole 11, when the threaded rod 12 rotates to the position, the threaded rod 12 passes through the positioning hole 11 on the roller fixing shaft 9, and fixes the test roller 10 on the roller base 6.

[0034] Then, by using the pusher 2 in conjunction with the pusher bracket 3 and the wheel 5, the distance between the two roller mounting platforms 4 can be adjusted so that the distance between the two test rollers 10 can meet the testing requirements. At the same time, the compression rod 19 and the compression spring 20 can provide a buffer for the roller mounting platform 4 during the adjustment process to avoid damage to the components due to excessive adjustment speed. When the pusher 2 stops working, the compression spring 20 uses its own characteristics to pull the test roller 10 tightly against the rubber friction wheel 22 to ensure the fit between the two.

[0035] Next, the protective cover 33 is closed and secured by the safety hook 34. The cover travel limit 35 can limit the range of movement of the protective cover 33 to prevent the protective cover 33 from being damaged due to excessive movement. Then, the motor 21 is started by the control switch 26 on the electrical control box 25. The motor 21 will drive the rubber friction wheel 22 to rotate. The rotation of the rubber friction wheel 22 will contact the test roller 10 and drive the test roller 10 to rotate, simulating the actual working state of the test roller 10. The polyurethane wear-resistant coating 23 can extend the service life of the rubber friction wheel 22.

[0036] During the test, the grease collection box 16 can collect the grease generated during the rotation of the test roller 10. The metal filter screen 17 and the oil-absorbing cotton 18 can filter and absorb impurities in the grease, facilitating the recycling and reuse of the grease. At the same time, the pressure sensor 32 can monitor the pressure of the safety pin 31. When the pressure exceeds the set value, the pressure sensor 32 will transmit the signal to the electrical control box 25. The electrical control box 25 will control the motor 21 to stop running through the time relay 28 and the frequency converter 27 to avoid safety accidents. In case of emergency, the emergency stop button 29 can be pressed to directly stop the operation of the motor 21 to ensure the safety of the operator.

[0037] After the test is completed, turn off the motor 21 by controlling switch 26, then open the protective cover 33, then loosen the threaded rod 12 by rotating knob 15, and then loosen the roller fixing shaft 9. Finally, remove the test roller 10 from the roller fixing shaft 9, then close the protective cover 33 and turn off the power.

[0038] This roller assembly quality testing platform, through the cooperation of components such as pusher 2, threaded rod 12, motor 21, grease collection box 16, compression rod 19, pressure sensor 32 and protective cover 33, can realize functions such as fixing, adjusting, driving, grease collection, buffering protection, safety monitoring and personnel protection of the test roller 10, ensuring the accuracy and safety of roller assembly quality testing, and improving testing efficiency and pass rate.
