Description

Technical Field

[0001] This utility model belongs to the field of built-in rotor detection technology, specifically relating to a semi-automatic weight reduction balancing machine. Background Technology

[0002] The rotor built into air purifiers and robot vacuum cleaners is a "key power transmission component" that enables the core functions of the equipment. It needs to be balanced after production. Imbalance in the rotor built into air purifiers and robot vacuum cleaners can cause problems such as airflow turbulence, increased noise, and a sharp reduction in lifespan. Therefore, a shock-absorbing balancing machine is needed to detect and correct it.

[0003] As disclosed in utility model patent CN212340543U, a mass balancing machine for large-sized flywheels includes a balancing machine body. A side housing is located on the left outer surface of the balancing machine body, and a fixed platform is located on the right outer surface. A support rod is located on the upper outer surface of the fixed platform. A turntable is located on the upper outer surface of the balancing machine body, and a transparent cover is located on the upper outer surface of the balancing machine body near the rear end of the turntable. A handle is located on the upper outer surface of the transparent cover. This design, by using a transparent cover, prevents the flywheel from loosening and flying out during use, thus preventing injury. It also allows observation of the flywheel's status. The inclusion of hydraulic jacks, sliders, and connecting grooves significantly absorbs vibrations generated by the balancing machine during use, reducing damage to the control panel.

[0004] However, the aforementioned balancing machine cannot locate the unbalanced position of the rotor during use, and it cannot perform quality reduction correction on the unbalanced position after detection, thus failing to enable the rotor to quickly reach a balanced state. Therefore, we propose a semi-automatic quality reduction balancing machine. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a semi-automatic weight reduction balancing machine, including a lower frame, a worktable mounted on the lower frame, and an upper support mounted on the worktable. A balancing test mechanism for balancing the built-in rotor is provided on one side of the worktable.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 This utility model provides a technical solution: a semi-automatic weight reduction balancing machine, including a lower frame 8, a worktable 7 set on the lower frame 8 and an upper support set on the worktable 7. A balancing test mechanism 1 for balancing the built-in rotor 9 is set on one side of the worktable 7. A clamping adjustment mechanism 2 for adjusting the rotation angle of the built-in rotor 9 is set on the worktable 7 on one side of the balancing test mechanism 1. A milling weight reduction motion mechanism 6 for cutting the built-in rotor 9 is set on the worktable 7 on one side of the clamping adjustment mechanism 2. The balance testing mechanism 1 includes a balance pendulum 11, which is set on one side of the workbench 7. A support frame 12 is set inside the balance pendulum 11, and a rotary motor 13 is set inside the support frame 12. A carrier plate is set on the main shaft of the rotary motor 13, and a number of pneumatically controlled clamping blocks 14 are evenly arranged on the carrier plate. Specifically, three sets of clamping blocks 14 are set, and the cylinders in the three sets of clamping blocks 14 can be synchronously controlled to clamp and fix the bottom of the built-in rotor 9 for balance testing, and at the same time drive the built-in rotor 9 to rotate and perform balance detection.

[0018] When testing the built-in rotor 9, the bottom of the built-in rotor 9 is first placed on the carrier plate. The three sets of clamping blocks 14 are controlled simultaneously to center and clamp the bottom of the built-in rotor 9. The servo motor 24 drives the rotating slide 29 to rotate. The rotating slide 29 drives the infrared ranging sensor 25 to rotate through the sensor bracket 26, and moves the infrared ranging sensor 25 to the upper side of the built-in rotor 9. The rotating motor 13 drives the carrier plate to rotate, and the carrier plate drives the built-in rotor 9 to rotate. The infrared ranging sensor 25 can detect the offset and unbalanced position of the built-in rotor 9 during rotation. The operator can mark the unbalanced position with a marker.

[0019] Please see Figure 6 as well as Figure 7 The clamping and adjusting mechanism 2 includes a main frame 21, which is mounted on the worktable 7. A lifting cylinder 22 is mounted on the top of the main frame 21. A sub-frame 23 is mounted on one end of the piston rod of the lifting cylinder 22, and a servo motor 24 is mounted on one end of the sub-frame 23. A rotary slide 29 is mounted on the spindle of the servo motor 24. A connecting frame 28 is mounted on one side surface of the rotary slide 29. The height of the rotary slide 29 can be adjusted by the lifting cylinder 22, thereby adjusting the height of the built-in rotor 9 after clamping. The rotation angle of the rotary slide 29 can be adjusted by the servo motor 24, thereby adjusting the angle of the built-in rotor 9. Two sets of opposing workpiece grippers 27 are mounted on one side surface of the connecting frame 28. The workpiece grippers 27 can clamp the built-in drill after balance testing.

[0020] After the built-in rotor 9 has completed the inspection, the sub-frame 23 is moved up and down by the lifting cylinder 22. The sub-frame 23 moves up and down by the rotating slide 29. The rotating slide 29 moves up and down by the workpiece gripper 27. The workpiece gripper 27 moves to both sides of the built-in rotor 9. Then, by driving the two sets of workpiece grippers 27 to move in opposite directions, the built-in rotor 9 is clamped and fixed. At this time, the three sets of clamping blocks 14 are released. Then, the rotating slide 29 is rotated by the servo motor 24. The rotating slide 29 rotates the built-in rotor 9 and rotates it to the milling angle of the milling and reducing motion mechanism 6.

[0021] The two sets of workpiece grippers 27 in this application can adopt a gear and rack cooperation structure. The rotation of the gear drives the two sets of racks to rotate in opposite directions, thereby controlling the opposite movement of the two sets of workpiece grippers 27 to achieve workpiece clamping.

[0022] Furthermore, a clamping cylinder 30 is installed inside the subframe 23. A pressure head is rotatably mounted on the piston rod of the clamping cylinder 30. The center position of the pressure head is on the same longitudinal line as the center position of the built-in rotor 9 after clamping, which can assist in clamping and fixing the end of the built-in rotor 9.

[0023] Furthermore, a sensor bracket 26 is provided on one side of the rotating slide 29, and an infrared ranging sensor 25 is installed at an angle on the sensor bracket 26. The infrared ranging sensor 25 is model GP2D15, which can detect and locate the unbalanced position in the balance test.

[0024] Please see Figure 8 as well as Figure 9 The milling and reducing motion mechanism 6 includes a bottom support 61, which is mounted on the worktable 7. A support platform 69 is mounted on the bottom support 61. A vertical frame 64 is mounted on one side of the support platform 69, and a mounting frame 63 is mounted on one side of the vertical frame 64. A milling motor 68 is mounted on the mounting frame 63. A milling cutter mounting head 67 is mounted on the spindle of the milling motor 68, and a milling cutter is mounted on the milling mounting head. An X-axis drive assembly 62 for controlling the lateral movement of the support platform 69 is mounted on the bottom support 61, and a Z-axis drive assembly 65 for controlling the longitudinal movement of the mounting frame 63 is mounted on the vertical frame 64.

[0025] When the built-in rotor 9 rotates to the milling position, the Z-axis drive assembly 65 drives the mounting bracket 63 to adjust the height in the Z-axis direction, and at the same time adjusts the height of the milling cutter, moving the milling cutter to the marked height on the surface of the built-in rotor 9. The milling motor 68 drives the milling cutter mounting head 67 to rotate, and the X-axis drive assembly 62 controls the support platform 69 to move in the X-axis direction. The support platform 69 drives the upright 64 to move in the X-axis direction, and the upright 64 drives the milling cutter to move in the X-axis direction, thereby controlling the feed rate of the milling cutter. The milling cutter corrects the unbalanced position of the built-in rotor 9. During the correction process, the servo motor 24 can control the rotation of the rotary slide 29, thereby controlling the rotation of the built-in rotor 9 and adjusting the milling range.

[0026] Furthermore, a smoke exhaust pipe 66 is also provided on one side of the mounting bracket 63. The smoke exhaust pipe 66 extends to the milling cutter position and is connected to an industrial vacuum cleaner, which can clean up dust during the milling correction process.

[0027] The X-axis drive assembly 62 and Z-axis drive assembly 65 in this application both adopt a lead screw and four-lead screw structure.

[0028] An industrial control computer is also installed inside the upper frame 4 of this application. The industrial control computer can control the rotary motor 13 and the servo motor 24. At the same time, the industrial control computer can also control the X-axis drive assembly 62 and the Z-axis drive assembly 65. The infrared sensor is connected to the industrial control computer. The industrial control computer also inputs a balance threshold. If it is greater than the balance threshold, it is determined to be an unbalanced built-in rotor 9, and subsequent correction milling operations are performed.

[0029] Meanwhile, a display screen 5 is also installed on the upper frame 4 to display various parameters, and a control switch 3 is also installed to control the milling motor 68, the clamping block 14 and the workpiece gripper 27.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
