Description

Technical Field

[0001] This invention relates to the field of dynamic balancing machine technology, specifically a weighing and measuring mechanism for an intelligent dynamic balancing machine. Background Technology

[0002] A balancing machine is a device specifically designed to measure the magnitude and phase position of imbalance in a rotating object. During rotation, if the center of mass of a rotor does not coincide with its axis of rotation, centrifugal force is generated. This centrifugal force caused by imbalance leads to unnecessary vibrations in the rotor bearings, which not only increases noise but may also accelerate bearing wear, thus significantly reducing product performance and expected lifespan. Therefore, it is crucial to perform precise balancing correction using a balancing machine before the product leaves the factory.

[0003] Before conducting a dynamic balancing test on a rotor, a weight measurement is usually required to ensure the accuracy of the test. For example, in the prior art, CN 118603415 B describes a weighing mechanism for a vertical dynamic balancing machine, including a base, support frame, horizontal positioning plate, mounting base, and support plate. Adjusting blocks are fixedly installed on all four sides of the mounting base. The horizontal positioning plate is configured with a U-shaped structure, and the mounting base is located inside the horizontal positioning plate without contacting it. All four adjusting blocks are located below the horizontal positioning plate. This invention enables rapid measurement of the weight of the part to be tested, facilitating the addition or removal of weight from the workpiece. After weighing, when continuing the dynamic balancing test, the lifting assembly, in conjunction with the adjusting blocks, can lift and adjust the mounting base to a horizontal state, ensuring the dynamic balancing test mechanism on the mounting base remains horizontal and guaranteeing the accuracy of the dynamic balancing test. Furthermore, the adjusting blocks are fixed in place by the pressure ring and the horizontal positioning plate, ensuring the stability of the mounting base.

[0004] However, most existing dynamic balancing machines use load cells for their weighing mechanisms, requiring the rotor to be moved to the weighing mechanism first using a rotor clamping tool before being moved to the dynamic balancing test station. This is inefficient and prevents weighing from being performed during the rotor clamping and transport process. Therefore, the key technological breakthrough lies in simplifying and improving the switching between the position states of the traditional electronic crane scale and the rotor clamping tool. Thus, this paper proposes a weighing measurement mechanism for an intelligent dynamic balancing machine that enables rapid and efficient weighing during rotor clamping. Summary of the Invention

[0005] The purpose of this invention is to provide a weighing and measuring mechanism for an intelligent dynamic balancing machine that has a fast and efficient weighing function during rotor clamping in order to solve the above-mentioned problems.

[0006] The present invention achieves the above-mentioned objectives through the following technical solution: a weighing and measuring mechanism for an intelligent dynamic balancing machine, comprising an electronic weighing device, an arc plate, a connecting rod, a side clamping plate, a positioning ring block, a round iron core, an electromagnet block, a motor, a round insert block, and a cylinder. The electronic weighing device is installed inside a U-shaped carrier plate, and two cylinders are symmetrically installed at both ends of the U-shaped carrier plate. A round insert block is installed at the output end of each cylinder, and the round insert block and the corresponding positioning ring block form an insertion and fixing structure. A connecting rod is rotatably installed inside the end grooves at both ends of the arc plate. A torsion spring is fitted at both ends of the connecting rod, and a round iron core is installed at one end of the connecting rod. An electromagnet block is arranged in front of the round iron core, and the middle of the back of the electromagnet block is connected to the shaft end of the motor. One end of the side clamping plate is fixedly connected to the connecting rod.

[0007] Preferably, a rectangular protrusion is provided in the middle of the arc plate, and the top surface of the rectangular protrusion is fixedly connected to the four positioning ring blocks distributed in a matrix.

[0008] Preferably, a hook is installed at the middle position of the top of the rectangular protrusion, and the hook is connected to the weighing and measuring end of the electronic weighing device.

[0009] Preferably, the end of the motor is fixedly mounted on the L-shaped side plate, and one end of the L-shaped side plate is fixedly connected to one side of the U-shaped carrier plate.

[0010] Preferably, a robotic arm connector is fixedly installed on the top of the L-shaped side plate.

[0011] Preferably, the side clamps are initially folded inwards, and the two side clamps and the arc plate form a rotor clamping structure to be tested.

[0012] The beneficial effects of this invention are: by using an electromagnet block to magnetically fix or release the circular iron core located at the end of the linkage rod, and in conjunction with a cylinder to insert the connected circular insert into or remove it from the positioning ring block, the state of the rotor-related structure can be quickly switched, ensuring that the rotor is not affected by external forces during weighing. This facilitates instantaneous and rapid weighing during clamping and transportation, resulting in more accurate weighing data. It solves the problem that hoisting and clamping structures are inconvenient to use with traditional electronic crane scales for accurate weighing, thereby improving overall work efficiency.

[0019] Please see Figure 1-3As shown, a weighing and measuring mechanism for an intelligent dynamic balancing machine includes an electronic weighing device 1, an arc plate 2, a connecting rod 3, a side clamping plate 4, a positioning ring block 6, a round iron core 7, an electromagnet block 8, a motor 9, a round insert block 10, and a cylinder 11. The electronic weighing device 1 is installed inside a U-shaped carrier plate 13, and two cylinders 11 are symmetrically installed at both ends of the U-shaped carrier plate 13. A round insert block 10 is installed at the output end of each cylinder 11, and the round insert block 10 and the corresponding positioning ring block 6 form an insertion and fixing structure. A connecting rod 3 is rotatably installed inside the end grooves 210 at both ends of the arc plate 2. Torsion springs 12 are fitted at both ends of the connecting rod 3, and a round iron core 7 is installed at one end of the connecting rod 3. An electromagnet block 8 is arranged in front of the round iron core 7, and the middle of the back of the electromagnet block 8 is connected to the shaft end of the motor 9. One end of the side clamping plate 4 is fixedly connected to the connecting rod 3.

[0020] A rectangular protrusion 5 is provided in the middle of the arc plate 2, and the top surface of the rectangular protrusion 5 is fixedly connected to the four positioning ring blocks 6 distributed in a matrix. The four positioning ring blocks 6 are divided into two groups diagonally. The two positioning ring blocks 6 in each group are in a state of synchronous insertion or synchronous separation with the two circular insert blocks 10 directly above, and the two groups of positioning ring blocks 6 are not synchronized.

[0021] A hook 510 is installed at the middle of the top of the rectangular protrusion 5, and the hook 510 is connected to the weighing measuring end of the electronic weighing device 1. The hook 510 facilitates the electronic weighing device 1 to weigh the clamped rotor.

[0022] The end of the motor 9 is fixedly mounted on the L-shaped side plate 14, and one end of the L-shaped side plate 14 is fixedly connected to one side of the U-shaped carrier plate 13, so as to achieve the effect of installing and fixing the two motors 9.

[0023] The top of the L-shaped side plate 14 is fixedly installed with a robotic arm connector 15. Through the robotic arm connector 15, it can be connected to an external intelligent robotic arm to complete the transfer of the rotor.

[0024] The side clamping plates 4 are initially folded inward, and the two side clamping plates 4 and the arc plate 2 form a rotor clamping structure to be tested. Under the action of the torsion spring 12, the side clamping plates 4, which are initially folded inward, play the role of clamping the rotor on the inside.

[0025] The specific steps for using this method are as follows: Step 1: The electronic weighing device 1 is zeroed under the rectangular protrusion 5 and its connecting structure. At this time, the rectangular protrusion 5, the arc plate 2, the side clamping plate 4 and the connecting structure are all in a state of self-weight suspension. Step 2: When the electromagnet block 8 is energized, it magnetically attracts the round iron core 7 in front of it, so that the connecting rod 3, side clamping plate 4, arc plate 2 and rectangular protrusion 5 connected to the round iron core 7 are in different fixed states. At this time, the positioning ring block 6 is located directly below the round insert block 10. Step 3: When the cylinder 11 is in the extended state, it can push the circular insert 10 connected to the cylinder 11 down into the corresponding positioning ring block 6, which mainly serves to bind and fix the arc plate 2 so that the side clamping plate 4 can be rotated laterally. Step 4: Based on Step 2 and Step 3, the motor 9 drives the electromagnet block 8 to rotate, which in turn drives the magnetically connected round iron core 7, connecting rod 3 and side clamp 4 to rotate, so as to change the side clamp 4 from being folded inward to being unfolded outward. Step 5: When most of the rotor is located between the two side clamping plates 4, the current of the electromagnet block 8 gradually decreases and the magnetic field strength gradually weakens. Combined with the torsion springs 12 connected to both ends of the connecting rod 3, the side clamping plates 4 can be gradually reset and the rotor can be clamped. Finally, the rotor is firmly clamped between the arc plate 2 and the two side clamping plates 4. Step 6: The two sets of circular inserts 10 located at the diagonal are orderly retracted by the cylinder 11 and moved out from the positioning ring block 6. At this time, the electromagnet block 8 is in a de-energized state and no longer aligns with the circular iron core 7. The external force restraint on the arc plate 2 and the side clamping plate 4 is completely released to weigh the clamped rotor. Step 7: After weighing is completed, quickly return to the operation state of Step 2 and Step 3. This serves to fix all related structures in place after weighing, so as to facilitate subsequent location transfer operations. Step 8: When the weighed rotor is moved to the dynamic balancing test station structure, execute step 4 to release the clamps on the rotor, so that the rotor is moved to the dynamic balancing test station structure. In summary: By using the electromagnet block 8 to magnetically fix or release the circular iron core 7 located at the end of the connecting rod 3, and in conjunction with the cylinder 11 to insert the connected circular insert block 10 into or remove it from the positioning ring block 6, the state of the rotor-related structure can be quickly switched, ensuring that the rotor is not affected by external forces during weighing. This facilitates instantaneous and rapid weighing during clamping and transportation, resulting in more accurate weighing data. It solves the problem that the hoisting and clamping structure is inconvenient to use with traditional electronic crane scales for accurate weighing, thus improving overall work efficiency.
