Technical Field
[0001] This utility model relates to the field of dynamic calibration technology for grinding machines, and in particular to a dynamic balancing calibration device for a double-end grinding machine. Background Technology
[0002] A double-end face grinder is a machine tool used to simultaneously grind both end faces of a workpiece. It can efficiently and precisely machine various disc-shaped, ring-shaped, and other workpieces, ensuring parallelism, perpendicularity, and shape accuracy. Double-end face grinders typically employ hydraulic, pneumatic, or electric control systems to achieve automated or semi-automated operation. Its main structure includes a grinding head, a worktable, a hydraulic system, and an electrical control system. The grinding head is usually equipped with two grinding wheels, which grind the upper and lower end faces of the workpiece respectively. Double-end face grinders are widely used in the automotive, aerospace, and electronics industries.
[0003] In practical applications, the grinding wheel alignment process of a double-end grinding machine is often accompanied by instability, which causes the grinding wheel to wobble during operation and accelerates excessive wear of the grinding wheel.
[0004] During the calibration of grinding wheels, their balance is difficult to guarantee. This imbalance causes vibrations during grinding, directly affecting grinding accuracy. Vibration not only affects the surface quality of the workpiece but can also lead to inconsistencies in workpiece dimensions, thus reducing processing efficiency and product quality.
[0005] The unstable correction process of the grinding wheels increases the maintenance cost of the equipment. Due to the imbalance and excessive wear of the grinding wheels, frequent replacement and adjustment of the grinding wheels are required, which not only increases the consumption of the grinding wheels, but also increases the workload and maintenance time of maintenance personnel.
[0006] The problems of grinding wheel wobbling and excessive wear also lead to increased equipment downtime. In order to correct the imbalance of the grinding wheels and replace worn grinding wheels, the equipment needs to be shut down regularly, which not only affects the production schedule but also reduces the utilization rate of the equipment. Utility Model Content
[0007] The main objective of this invention is to provide a dynamic balancing correction device for a double-end face grinder, which can effectively solve the problems mentioned in the background art.
[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0009] A dynamic balancing correction device for a double-end grinding machine includes a machine base, a drive device, a material channel, and a grinding wheel assembly. The drive device is installed on both sides of the upper end of the machine base, and the material channel and the grinding wheel assembly are located in the middle section of the upper end of the machine base. The grinding wheel assembly performs cutting and grinding operations on the material conveyed by the material channel.
[0010] The grinding wheel assembly has a mounting cover on its side, and the end face of the mounting cover has a mounting cavity. A T-shaped frame is installed in the mounting cavity, and the side end of the T-shaped frame has a limiting groove and a through groove. The T-shaped frame corresponds to the grinding wheel assembly.
[0011] An eccentric wheel is inserted into the through slot of the T-shaped frame, and the upper limit block of the eccentric wheel is embedded in the limit slot. The eccentric wheel is connected to the drive connector through the connecting adapter. The drive connector is connected to the drive motor of the grinding wheel assembly. The dynamic balance correction of the grinding wheel of the grinding machine is achieved by driving the eccentric wheel to move through the drive connector.
[0012] In a further optional embodiment of this utility model, the drive device is fixed to the machine base by bolts, and the drive device is connected to the drive structure of the grinding wheel assembly by a transmission belt;
[0013] In a further optional embodiment of this utility model, the mounting cover is fixed to the housing of the grinding wheel assembly by bolts and nuts, and the mounting cover is connected to the housing of the grinding wheel assembly.
[0014] In a further optional embodiment of this utility model, the through groove is located on the outer protrusion of the T-shaped frame, the limiting groove is located on the inner straight plate of the T-shaped frame, and the edge lines of the through groove and the through groove are designed to be parallel.
[0015] In a further optional embodiment of this utility model, the eccentric wheel passes through the through groove, and the eccentric wheel makes arc-shaped movement through the through groove and the limiting groove to achieve dynamic correction operation;
[0016] In a further optional embodiment of this utility model, the eccentric wheel is divided into a straight bar section and a counterweight wheel section. The counterweight wheel section is located at both ends of the straight bar section. The weights of the two counterweight wheel sections are not the same. The position of the counterweight wheel section is changed by driving the eccentric wheel through the drive connector, thereby realizing the dynamic balance correction operation.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] In this invention, precise dynamic balancing correction ensures stability during the grinding process, thereby improving the surface finish and precision of the processed workpiece. It reduces vibration and impact caused by imbalance, protecting the grinding wheel assembly, extending its service life, and reducing replacement frequency and costs. The dynamic balancing correction device reduces downtime and malfunctions caused by imbalance, lowering the complexity and cost of maintenance. The double eccentric wheel design and their coordinated operation make dynamic balancing correction more precise and efficient, enhancing the overall performance and stability of the grinding machine.
[0019] A stable grinding process reduces downtime for setup and improves production efficiency and output, bringing greater economic benefits to enterprises. Furthermore, the increased machining precision enhances product consistency and reliability, contributing to improved market competitiveness. Simultaneously, reduced vibration and impact extend the lifespan of the grinding wheel assembly and lower energy consumption, aligning with current industrial trends towards energy conservation and emission reduction.
[0020] In terms of operation, the introduction of the dynamic balancing correction device simplifies the operation of the grinding machine, reduces reliance on operator skills, and lowers training and human resource costs. Furthermore, due to the reduced failure rate and extended maintenance cycles, the total cost of ownership of the equipment is effectively controlled, further improving the company's return on investment.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0027] like Figure 1 - Figure 4 As shown, a dynamic balancing correction device for a double-end face grinder includes a base 1, a drive unit 2, a feed channel 3, and a grinding wheel assembly 4. The drive unit 2 is installed on both sides of the upper end of the base 1, and the feed channel 3 and the grinding wheel assembly 4 are located in the middle section of the upper end of the base 1. The grinding wheel assembly 4 performs cutting and grinding operations on the items conveyed by the feed channel 3.
[0028] The grinding wheel assembly 4 has a mounting cover 5 on its side, and a mounting cavity 6 is formed on the end face of the mounting cover 5. A T-shaped frame 7 is installed in the mounting cavity 6. The side end of the T-shaped frame 7 has a limiting groove 8 and a through groove 9, and the T-shaped frame 7 corresponds to the grinding wheel assembly 4. An eccentric wheel 12 is inserted into the through groove 9 of the T-shaped frame 7, and the upper limit block of the eccentric wheel 12 is embedded in the limiting groove 8. The eccentric wheel 12 is connected to the drive connector 10 through the connecting adapter 11. The drive connector 10 is connected to the drive motor of the grinding wheel assembly 4. The drive connector 10 drives the eccentric wheel 12 to move, realizing the dynamic balance correction of the grinding wheel of the grinding machine.
[0029] The drive unit 2 is fixed to the base 1 by bolts, and the drive unit 2 is connected to the drive structure of the grinding wheel assembly 4 via a transmission belt. The mounting cover 5 is fixed to the housing of the grinding wheel assembly 4 by bolts and nuts, and the mounting cover 5 is in communication with the housing of the grinding wheel assembly 4.
[0030] The through groove 9 is located on the outer protrusion of the T-shaped frame 7, and the limiting groove 8 is located on the inner straight plate of the T-shaped frame 7. The edge lines of the through groove 9 and the limiting groove 8 are designed to be parallel. The eccentric wheel 12 passes through the through groove 9, and the eccentric wheel 12 moves in an arc shape through the through groove 9 and the limiting groove 8 to achieve dynamic correction operation.
[0031] The eccentric wheel 12 consists of a straight bar section and a counterweight wheel section, with the counterweight wheel sections located at both ends of the straight bar section. The two counterweight wheel sections have different weights. The eccentric wheel 12 is moved by the drive connector 10 to change the position of the counterweight wheel sections, thereby achieving dynamic balance correction. To improve correction accuracy, the counterweight wheel sections of the eccentric wheel 12 can be made of different materials, such as alloys of different densities, to ensure optimal balance at different speeds.
[0032] Furthermore, to further optimize the performance of the grinding machine, a dynamic balancing correction device with a structure similar to the eccentric wheel 12 can be installed on the other side of the grinding wheel assembly 4. Through the coordinated work of the two eccentric wheels, more precise dynamic balancing correction can be achieved. This design of a dynamic balancing correction device for a double-end face grinding machine not only improves grinding accuracy but also extends the service life of the grinding wheel and reduces production costs.
[0033] Operating procedure: The drive unit 2 is installed on both sides of the upper end of the base 1, and the feed channel 3 and grinding wheel assembly 4 are located in the middle of the upper end of the base 1. The grinding wheel assembly 4 performs cutting and grinding operations on the items conveyed by the feed channel 3.
[0034] During dynamic balancing: A mounting cover 5 is provided on the side of the grinding wheel assembly 4. A mounting cavity 6 is formed on the end face of the mounting cover 5, and a T-shaped frame 7 is installed inside the mounting cavity 6. A limiting groove 8 and a through groove 9 are formed on the side of the T-shaped frame 7. An eccentric wheel 12 is inserted into the through groove 9, and an upper limit block of the eccentric wheel 12 is embedded in the limiting groove 8. The eccentric wheel 12 is connected to the drive connector 10 via a connecting adapter 11, and the drive connector 10 is connected to the drive motor of the grinding wheel assembly 4. The drive connector 10 drives the eccentric wheel 12 to move, thus achieving the dynamic balancing of the grinding wheel.
[0035] The eccentric wheel 12 consists of a straight bar section and a counterweight wheel section. The counterweight wheel sections are located at both ends of the straight bar section, and the weights of the two counterweight wheel sections are different. The eccentric wheel 12 is moved by the drive connector 10 to change the position of the counterweight wheel section, thereby achieving dynamic balance correction. To improve correction accuracy, the counterweight wheel section of the eccentric wheel 12 can be made of different materials, such as alloy materials of different densities, to ensure that optimal balance is achieved at different speeds.
[0036] On the other side of the grinding wheel assembly 4, a dynamic balancing correction device similar in structure to the eccentric wheel 12 can be installed. Through the coordinated operation of the two eccentric wheels, more precise dynamic balancing correction can be achieved. This design not only improves grinding accuracy but also extends the service life of the grinding wheel and reduces production costs. The above process demonstrates the use of the dynamic balancing correction device for the double-end face grinder, the specific steps of dynamic balancing correction, and the optimization measures taken to improve correction accuracy and grinder performance.
[0037] This invention ensures the stability of the grinding process through precise dynamic balancing correction, thereby improving the surface finish and precision of the processed workpiece. It reduces vibration and impact caused by imbalance, protects the grinding wheel assembly, extends its service life, and lowers replacement frequency and costs. The dynamic balancing correction device reduces downtime and malfunctions caused by imbalance, lowering the complexity and cost of maintenance. The double eccentric wheel design and their coordinated operation make dynamic balancing correction more precise and efficient, improving the grinding machine's performance and stability. The stable grinding process reduces downtime for adjustments, increases production efficiency and output, and brings greater economic benefits to enterprises.
