Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dynamic balancing machines, and particularly relates to a weighing measurement mechanism of a smart dynamic balancing machine. BACKGROUND

[0002] A balancing machine is a device specially used for measuring the size and phase position of the unbalance of a rotating object. If the center of mass of a rotor does not coincide with its rotation axis during rotation, centrifugal force will be generated. The centrifugal force caused by the unbalance will cause unnecessary vibration of the rotor bearing, which not only increases noise, but also can accelerate the wear of the bearing, thereby significantly reducing the operating performance and expected life of the product. Therefore, it is essential to use a balancing machine to perform accurate balancing correction on the product before it is shipped.

[0003] Before performing dynamic balancing test on a rotor, weight measurement is usually required to ensure the accuracy of the test, such as the weighing mechanism of a vertical dynamic balancing machine in the prior art CN 118603415 B, which comprises a base, a support frame, a horizontal positioning plate, a mounting base and a support plate, four adjusting blocks are fixedly installed on the four edges of the mounting base, the horizontal positioning plate is arranged in a meandering structure, the mounting base is located on the inner side of the horizontal positioning plate and does not contact the horizontal positioning plate, and the four adjusting blocks are located below the horizontal positioning plate; the present application realizes rapid measurement of the weight of the measured part, so as to facilitate the weight adding or removing operation of the workpiece. When the weighing is completed and the dynamic balancing test is continued, the mounting base can be lifted up and adjusted to a horizontal state by the jacking assembly cooperating with the adjusting blocks, so that the dynamic balancing test mechanism on the mounting base can be kept horizontal to ensure the dynamic balancing detection precision, and the adjusting blocks can be fixed by the pressing ring and the horizontal positioning plate, so that the mounting base remains stable.

[0004] However, most of the existing weighing mechanisms of dynamic balancing machines use weighing sensors, so that the rotor needs to be moved to the weighing mechanism first and then to the dynamic balancing test station by using a rotor clamping tool, which is low in efficiency and cannot implement weighing during the rotor clamping and transfer process. Therefore, how to switch the position state between the traditional electronic hanging scale and the rotor clamping tool as a key technical breakthrough point for simplifying efficient weighing. Therefore, in view of the above problems, a weighing measurement mechanism of a smart dynamic balancing machine with rapid and efficient weighing function during rotor clamping is proposed. SUMMARY

[0005] The purpose of the present application is to provide a weighing measurement mechanism of a smart dynamic balancing machine with rapid and efficient weighing function during rotor clamping to solve the above problems.

[0006] The weighing measuring mechanism of the intelligent dynamic balance machine comprises an electronic scale, a circular arc plate, a linkage rod, a side clamping plate, a positioning ring block, a circular iron core, an electromagnet block, a motor, a circular plug block and a cylinder.

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

[0008] Preferably, a hooking piece is arranged on the top middle position of the rectangular protrusion, and the hooking piece is connected with the weighing measuring end of the electronic scale.

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

[0010] Preferably, a mechanical hand connecting piece is fixedly arranged on the top of the L-shaped side plate.

[0011] Preferably, the initial state of the side clamping plate is inwardly folded, and a to-be-measured rotor clamping structure is formed between the two side clamping plates and the circular arc plate.

[0012] The beneficial effects of the present application are as follows: the circular iron core at the end of the linkage rod is magnetically attracted and fixed or released by the electromagnet block, and the circular plug block connected by the cylinder is inserted into or removed from the positioning ring block, so that the state of the rotor associated structure is quickly switched, ensuring that the rotor is not affected by external force during weighing, which is beneficial to instantaneous and rapid weighing during clamping and transporting, the weighing data is more accurate, the problem of inconvenient cooperation of the hoisting and clamping structure with the traditional electronic hoist scale for accurate weighing is solved, and the overall work efficiency is improved.

[0022] The middle part of the circular arc plate 2 is provided with a rectangular protrusion 5, and the top surface of the rectangular protrusion 5 is fixedly connected with the four matrix distributed positioning ring blocks 6, which are divided into two groups by diagonal lines, and each group of two positioning ring blocks 6 is in synchronous insertion or synchronous separation state with the two round insert blocks 10 above it, and the two groups of positioning ring blocks 6 are not synchronized.

[0023] The top middle position of the rectangular protrusion 5 is provided with a hooking piece 510, and the hooking piece 510 is connected with the weighing measurement end of the electronic scale 1, so that the electronic scale 1 can conveniently weigh the clamped rotor by using the hooking piece 510.

[0024] The end of the motor 9 is fixedly installed on the L-shaped side plate 14, and one end of the L-shaped side plate 14 is fixedly connected with one side of the U-shaped carrier plate 13, so as to achieve the effect of installing and fixing two motors 9.

[0025] The top of the L-shaped side plate 14 is fixedly installed with a mechanical hand connecting piece 15, which can be connected with an external intelligent mechanical arm to complete the transfer of the rotor.

[0026] The initial state of the side clamping plate 4 is inwardly retracted, and the two side clamping plates 4 and the circular arc plate 2 form a rotor clamping structure to be measured, and under the action of the torsion spring 12, the initially inwardly retracted side clamping plate 4 plays a role in clamping the rotor on the inside.

[0027] The specific steps of the use method are as follows:

[0028] Step one, the electronic scale 1 is zeroed under the rectangular protrusion 5 and its connecting structure, at this time, the rectangular protrusion 5, the circular arc plate 2, the side clamping plate 4 and the connected structure are all in self-weight suspension state;

[0029] Step two, the electromagnet block 8 is powered to magnetically attract the round iron core 7 in front, so that the linkage rod 3, the side clamping plate 4, the arc plate 2 and the rectangular protrusion 5 connected with the round iron core 7 are in different fixed states, and the positioning ring block 6 is located directly below the round plug block 10;

[0030] Step three, the running cylinder 11 is in an extended state, which can push the round plug block 10 connected with the cylinder 11 downward to insert into the corresponding positioning ring block 6, mainly playing a role in restraining and fixing the arc plate 2, so as to implement the side turning action on the side clamping plate 4 subsequently;

[0031] Step four, based on steps two and three, the motor 9 drives the electromagnet block 8 to rotate, further driving the magnetically attracted round iron core 7, linkage rod 3 and side clamping plate 4 to be in a rotating state, achieving the effect of turning the side clamping plate 4 from inward folding to outward unfolding;

[0032] Step five, when the rotor is mostly located within the range between the two side clamping plates 4, the electromagnet block 8 gradually reduces the current and the magnetic field strength gradually weakens, and in combination with the torsion spring 12 connected at both ends of the linkage rod 3, the side clamping plate 4 can be gradually reset and clamp the rotor, and finally the rotor is firmly clamped between the arc plate 2 and the two side clamping plates 4;

[0033] Step six, the two groups of round plug blocks 10 located at the diagonal are sequentially moved out of the positioning ring block 6 by the contraction of the cylinder 11, at this time the electromagnet block 8 is in a power-off state and no longer magnetically attracts the round iron core 7, completely releasing the external force restraint on the arc plate 2 and the side clamping plate 4 to weigh the clamped rotor;

[0034] Step seven, after weighing, quickly enter the operation state of steps two and three again to fix all the related structures again, so as to facilitate subsequent position transfer operation;

[0035] Step eight, when the weighed rotor moves to the dynamic balance test station structure, step four is executed to release the clamping of the rotor, so that the rotor moves to the dynamic balance test station structure;

[0036] In summary: the electromagnet block 8 magnetically attracts or releases the magnetic attraction of the round iron core 7 at the end of the linkage rod 3, and in combination with the cylinder 11 inserting or moving out the connected round plug block 10 into or from the positioning ring block 6, the state of the rotor associated structure is quickly switched, ensuring that the rotor is not affected by external force during weighing, which is beneficial to instantaneous and rapid weighing during clamping and transfer, the weighing data is more accurate, and the problem of inconvenient cooperation of the lifting and clamping structure with the traditional electronic overhead scale accurate weighing is solved, and the overall work efficiency is improved.
