Description

Technical Field

[0001] The invention relates to the technical field of numerically controlled grinding machines, in particular to a grinding wheel dynamic balancing adjustment device for numerically controlled grinding machines. Background Art

[0002] The grinding wheel balancing adjustment device of a CNC grinding machine is a key functional component used in CNC grinding machine equipment. It uses sensors to monitor the imbalance state of the grinding wheel during high-speed rotation in real time, and automatically adjusts the position or weight distribution of the counterweight block inside the grinding wheel based on the precise calculation of the CNC system, thereby effectively reducing the vibration caused by the imbalance of the grinding wheel, improving the grinding accuracy and surface quality, extending the service life of the grinding wheel and machine tool components, and ensuring the efficient and stable operation of the CNC grinder.

[0003] After long-term use, the grinding wheel will wear out or be partially damaged, resulting in changes in the mass distribution of the grinding wheel. When such a grinding wheel rotates at high speed, it is prone to fine vibration and increased noise, which reduces the grinding accuracy of the CNC grinder. In the operation of adjusting the counterweight of the grinding wheel to optimize the weight distribution on both sides, the traditional bolt installation method is cumbersome and time-consuming, which is difficult to meet the actual needs of efficient adjustment, and to a certain extent restricts the production efficiency and precision stability of the grinding process.

The dynamic balancing adjustment machine is used to detect the unbalanced centrifugal force and torque generated during the rotation of the grinding wheel assembly, and determine the size and position of the unbalanced amount of the grinding wheel. The counterweight assembly adjusts the weight distribution of the grinding wheel by being clamped at the unbalanced position of the grinding wheel assembly, and the symmetrical counterweight extrusion assembly symmetrically squeezes the two groups of counterweight assemblies so that they can be clamped into the slot on one side of the grinding wheel assembly.

[0006] Preferably, the grinding wheel assembly includes a mounting ring, an outer limiting ring, an inner limiting ring, and a grinding ring. The grinding ring is fixedly mounted on the outside of the mounting ring. A positioning hole is provided at the center of the mounting ring. Two outer limiting rings and two inner limiting rings are respectively fixedly connected on both sides of the mounting ring, and the inner limiting ring is arranged inside the outer limiting ring.

[0007] Preferably, the counterweight assembly is movably clamped between the outer limiting ring and the inner limiting ring.

The turntable is rotatably connected to the center of the mounting frame, and two pressure plates are slidably connected to the two ends of the mounting frame. The pressure plate is used to press the adjusting pressure block. One side of the pressure plate is fixedly connected to one end of the adjusting rod, and the No. 1 rack is fixedly bonded to one side of the adjusting rod. A No. 2 toothed ring is fixedly installed on the outer side of the turntable, and the other end of the No. 1 rack is engaged with the outer side of the No. 2 toothed ring.

[0012] Preferably, rectangular grooves are provided at both ends of the mounting frame, a long plate is symmetrically fixedly connected to one side of the pressure plate, and the long plate is movable through the interior of the rectangular groove, and a No. 2 limit rod is fixedly connected to both ends of the mounting frame, and the No. 2 limit rod is movable through one end of the long plate.

If local wear or insufficient counterweight occurs, only the corresponding assembly needs to be replaced without disassembling the grinding wheel assembly as a whole.

[0017] 3. In the present invention, the symmetrical pressing operation of the symmetrical counterweight block extrusion assembly can simultaneously clamp two counterweight assemblies. Compared with the traditional method of installing single counterweight blocks one by one, the symmetrical pressing operation can improve the efficiency of single adjustment. During the installation of the counterweight assembly, the operator only needs to remotely control it by rotating the rotating ring, avoiding the risk of pinching hands that may occur during traditional manual pressing.

The symmetrical counterweight block extrusion assembly 4 includes a mounting frame 41, a pressure plate 42, an adjusting rod 43, a No. 1 rack 44 and a turntable 45. The turntable 45 is rotatably connected to the center of the mounting frame 41. The two pressure plates 42 are slidably connected to the two ends of the mounting frame 41. The pressure plate 42 is used to press the adjusting pressure block 324. One side of the pressure plate 42 is fixedly connected to one end of the adjusting rod 43. The No. 1 rack 44 is fixedly bonded to one side of the adjusting rod 43. The outer side of the turntable 45 is fixedly installed with a No. 2 toothed ring 46. The other end of the No. 1 rack 44 is connected to the outer side of the No. 2 toothed ring 46. The two sides are meshed with each other, and rectangular grooves 411 are provided at both ends of the mounting frame 41. A long plate 421 is symmetrically fixedly connected to one side of the pressure plate 42, and the long plate 421 is movable through the interior of the rectangular groove 411.

The rotating shaft 451 is fixedly installed at the center of one side of the pressure plate 452, and the rotating ring 453 is fixedly installed at the center of the other side of the rotating shaft 451. Support frames 413 are fixedly installed on both sides of the mounting frame 41. The support frames 413 The other end is fixedly connected to a slider 414, and the other side of the slider 414 is slidably connected to a slide rail 415. The counterweight assembly 3 includes an adjusting chamber 31, a clamping member 32, and a counterweight iron block 33. The clamping member 32 is movably clamped in the interior of the adjusting chamber 31, and the counterweight iron block 33 is fixedly installed on one side of the adjusting chamber 31. The other end of the clamping member 32 is symmetrically fixedly connected to a clamping strip 322, and a plurality of tooth grooves 323 are provided on one side of the clamping strip 322. A number of tooth grooves 323 are provided on one side of the outer limit ring 22. A number of toothed rings 221 are fixedly installed on one side of the outer limit ring 22. The clamping strip 322 is engaged with the number one toothed ring 221 through the tooth grooves 323, and an adjusting pressure block 324 is fixedly connected to one side of the clamping member 32.

[0027] In this embodiment, when pressing the adjusting pressure block 324, one end of the counterweight assembly 3 can be first inserted between the outer limit ring 22 and the inner limit ring 23, and then the mounting frame 41 is driven to slide on the slide rail 415, and the pressure plate 42 moves to one side of the adjusting pressure block 324, and the rotating ring 453 is rotated, so that the rotating ring 453 drives the rotating shaft 451 to rotate, and the rotating shaft 451 drives the second gear ring 46 to rotate, and the second gear ring 46 drives the two first racks 44 to move, so that the two pressure plates 42 move toward each other, and at the same time the two adjusting pressure blocks 324 are pressed together, so that the card The clip 322 on one side of the component 32 is retracted into the interior of the adjustment chamber 31, pushing the two counterweight assemblies 3 to slide between the outer limit ring 22 and the inner limit ring 23, and then dragging away the mounting frame 41. Through the symmetrical pressing operation of the symmetrical counterweight block extrusion assembly 4, the two counterweight assemblies 3 can be clamped at the same time. Compared with the traditional method of installing single counterweight blocks one by one, the symmetrical pressing operation can improve the efficiency of single adjustment; during the installation process of the counterweight assembly 3, the operator only needs to remotely control it by rotating the rotating ring 453, avoiding the risk of pinching hands that may be caused by traditional manual pressing.

[0028] The device's usage and operating principle are as follows: The assembled grinding wheel assembly 2 is mounted on the drive shaft of the dynamic balancing machine 1, and the dynamic balancing machine 1 is started. The dynamic balancing machine 1 uses high-precision sensors to monitor the unbalanced centrifugal force and torque generated by the grinding wheel assembly 2 during rotation in real time. Through its internal data processing and analysis system, the dynamic balancing machine 1 quickly and accurately determines the magnitude and specific location of the grinding wheel's imbalance, and displays this information using intuitive digital and graphical interfaces.

[0029] Based on the imbalance data displayed by the dynamic balancing machine 1, the operator determines the required installation position of the counterweight assembly 3 and engages the counterweight assembly 3 between the outer limit ring 22 and the inner limit ring 23. After completing the first counterweight adjustment, the dynamic balancing machine 1 is restarted to perform a second test on the grinding wheel assembly 2. If the test results show that a small imbalance still exists, the counterweight adjustment operation can be repeated to fine-tune the position of the counterweight assembly 3 until the dynamic balancing machine 1 indicates that the grinding wheel assembly 2 has achieved a good dynamic balance.

[0030] When the counterweight assembly 3 is clamped between the outer limit ring 22 and the inner limit ring 23, the adjusting pressure block 324 is squeezed, so that the clamping piece 32 squeezes the reset spring 312 downward, so that the clamping strip 322 on one side of the clamping piece 32 is retracted into the interior of the adjusting chamber 31, making it easier for the adjusting chamber 31 to be inserted between the outer limit ring 22 and the inner limit ring 23. The reset spring 312 releases its elastic potential energy and pushes out the clamping strip 322 on one side of the clamping piece 32 again. The tooth groove 323 on one side of the clamping strip 322 engages with the No. 1 toothed ring 221, so that the counterweight assembly 3 can achieve precise fixation at multiple points in the circumferential direction.

[0031] In addition, one end of the counterweight assembly 3 can be first inserted between the outer limit ring 22 and the inner limit ring 23, and then the mounting frame 41 can be driven to slide on the slide rail 415, and the pressure plate 42 moves to one side of the adjusting pressure block 324, and the rotating ring 453 is rotated so that the rotating ring 453 drives the rotating shaft 451 to rotate, and the rotating shaft 451 drives the No. 2 geared ring 46 to rotate, and the No. 2 geared ring 46 drives the two No. 1 racks 44 to move, so that the two pressure plates 42 move toward each other, and at the same time, the two adjusting pressure blocks 324 are pressed together, so that the clip 322 on one side of the clip 32 is retracted into the interior of the adjusting chamber 31, pushing the two counterweight assemblies 3 to slide between the outer limit ring 22 and the inner limit ring 23, and then dragging the mounting frame 41 away. Through the symmetrical pressing operation of the symmetrical counterweight block extrusion assembly 4, the two counterweight assemblies 3 can be clamped at the same time.
