Description

[0045] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0046] like Figures 1 to 7 As shown, a dynamic balance detection and processing equipment for a cast iron flywheel includes:

[0047] The dynamic balancing machine 10 automatically detects the imbalance of the flywheel assembly 40 through the dynamic balancing machine 10;

[0048] The processing mechanism 20 is arranged above the inspection table 101 and includes an electric push rod 203, a motor 209, and a drill bit 211. The motor 209 drives the drill bit 211 to rotate and automatically remove the imbalance. The electric push rod 203 drives the motor 209 and the drill bit 211 to rise and fall and automatically adjust the amount of the removed imbalance.

[0049] The protection mechanism 30 is arranged at the edge of the detection table 101 and comprises a protection plate one 301 and a protection plate two 307. The protection plate one 301 is arranged at the rear edge and the left and right edges of the detection table 101. The protection plate two 307 is arranged at the front edge of the detection table 101.

[0050] In the embodiment, the dynamic balancing machine 10 comprises a detection table 101, the center of which is provided with a rotating table 102, the center of the rotating table 102 is provided with a main positioning column 103, and the edge of the rotating table 102 is uniformly provided with a plurality of auxiliary positioning columns 104.

[0051] In the embodiment, the processing mechanism 20 further comprises a fixed frame 201 and a fixed plate 202. The fixed frame 201 is an H-shaped structure and is vertically connected to the upper side of the detection table 101. The fixed plate 202 is horizontally connected to the upper side of the fixed frame 201. The electric push rod 203 is vertically downwardly installed on the lower side of the fixed plate 202 through the hinge seat one 204. The lower end of the electric push rod 203 is horizontally connected with the lifting plate 206 through the hinge seat two 205. The left and right sides of the lifting plate 206 are symmetrically connected with a pair of guide columns 207. The guide columns 207 are slidingly connected with the fixed plate 202 through the guide sleeve 208. The electric motor 209 is vertically installed in the middle of the lifting plate 206. The drill bit 211 is coaxially connected to the output end of the electric motor 209 through the drill bit fixing seat 210.

[0052] In the embodiment, the dynamic balancing machine 10 further comprises a display screen 105, which is connected to the front edge of the fixed plate 202 through the connection frame 106 in the shape of “N”. Through the display screen 105, the unbalance amount of the dynamic balancing machine 10 when detecting the flywheel assembly 40 can be displayed.

[0053] In the embodiment, the drill bit 211 is coaxially sleeved with a collecting cover 212, and the collecting cover 212 is provided with a suction port 212a at the rear side thereof. The lower side of the collecting cover 212 is coaxially connected with a rubber sleeve 213. The left and right sides of the collecting cover 212 are symmetrically fixed with connecting plates 214. The left and right sides of the lifting plate 206 are slidingly connected with a pair of connecting columns 215. The lower end of the connecting column 215 is connected to the connecting plate 214 on the same side, and a compression spring one 216 is sleeved on the connecting column 215. The suction port 212a is communicated to the suction device through the corrugated pipe. The collecting cover 212 and the rubber sleeve 213 can avoid the debris generated by processing from being scattered everywhere on the detection table 101.

[0054] In this embodiment, the first protective plate 301 is vertically mounted on the upper side of the inspection platform 101 via a plurality of angle brackets 302. A pair of guide rails 303 are symmetrically connected to the front of the inspection platform 101, with sliders 304 slidably connected to the first guide rails 303. A pair of guide rails 305 are symmetrically connected to the left and right sides of the inspection platform 101, with sliders 306 slidably connected to the second guide rails 305. The second protective plate 307 is vertically connected to the first and second sliders 304 and 306 on the same side via a pair of connecting rods 308. The three first protective plates 301 provide effective protection at the rear and left and right sides of the inspection platform 101, while the pair of second protective plates 307 provide effective protection at the front of the inspection platform 101. This prevents the flywheel assembly 40 from flying off the inspection platform 101 during high-speed rotation, potentially causing personal injury.

[0055] In this embodiment, a hydraulic cylinder 309 is provided parallel to the second guide rail 305. The hydraulic cylinder 309 is connected to the upper side of the inspection platform 101 via a fixed base 310. The end of the piston rod of the hydraulic cylinder 309 is connected to an L-shaped movable plate 311, which is connected to the adjacent second slider 306. When the piston rod of the hydraulic cylinder 309 extends and pushes the second slider 306 forward along the second guide rail 305, the first slider 304 simultaneously moves inward along the first guide rail 303, thereby moving the second protective plate 307 to the front side of the inspection platform 101 to provide protection during inspection. When the piston rod of the hydraulic cylinder 309 retracts and pushes the second slider 306 backward along the second guide rail 305, the first slider 304 simultaneously moves outward along the first guide rail 303, thereby moving the second protective plate 307 to the left and right sides of the inspection platform 101, making it easier to remove and place the flywheel assembly 40 before and after inspection.

[0056] In this embodiment, the slider 1 304 is provided with a second compression spring 312 on the side close to the same-side guard plate 1 301, and the slider 2 306 is provided with a third compression spring 313 on the side close to the rear guard plate 1 301. The second compression spring 312 helps the slider 1 304 move inward along the guide rail 1 303, while the third compression spring 313 helps the slider 2 306 move forward along the guide rail 2 305.

[0057] The working principle of this cast iron flywheel dynamic balancing detection and processing equipment:

[0058] S1: Workpiece installation

[0059] Place the flywheel assembly 40 to be tested on the rotating table 102 of the dynamic balancing machine 10;

[0061] S2: Dynamic balance detection

[0062] The dynamic balancing machine 10 is started to drive the flywheel assembly 40 to rotate at high speed;

[0063] The vibration signal is collected by the sensor and the imbalance amount and its phase angle are calculated;

[0064] The imbalance information is displayed in real time via the display screen 105 .

[0065] S3: Automatic deduplication processing

[0066] The control system determines the drilling position based on the imbalance data;

[0067] The electric push rod 203 drives the lifting plate 206 to descend, so that the drill bit 211 is close to the surface of the flywheel assembly 40;

[0068] The motor 209 is started, driving the drill bit 211 to rotate and remove mass from the designated area;

[0069] During the processing, the collecting cover 212 and the rubber sleeve 213 prevent the debris from splashing, and the suction device assists in cleaning.

[0070] S4: Protection linkage control

[0071] Before the test begins, the hydraulic cylinder 309 pushes the second slide 306 to move the second protection plate 307 to the front side of the test platform 101;

[0072] After the processing is completed, the second protective plate 307 is retracted to both sides to facilitate the removal and placement of the flywheel assembly 40;

[0073] All protective actions are coordinated by the control system to ensure safe operation.

[0074] S5: Re-inspection and output

[0075] After completing one deweighting step, perform dynamic balancing test again;

[0076] If there is still imbalance, repeat the above steps until the balance standard is reached;

[0077] Finally, a test report is generated, recording the original imbalance value and correction results.

[0078] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
