Description

TECHNICAL FIELD

[0001] The application relates to the technical field of magnetic tile workpieces, in particular to a high-verticality shaft length grinding end face grinding machine. BACKGROUND

[0002] The motor magnetic tile is a tile-shaped magnet used in a permanent magnet motor, and a plurality of small regions with spontaneous magnetization and magnetic moments exist in a ferromagnetic or ferrimagnetic material below Curie temperature. The magnetic moments are arranged in disorder, and the magnetic moments are zero as a whole without a magnetic field. The small regions are called magnetic tiles. A strong exchange coupling exists between adjacent electrons in the ferromagnetic material. In the absence of an external magnetic field, the spin magnetic moments of the electrons can be spontaneously arranged in the small regions to form spontaneously magnetized small regions, namely the magnetic tiles. In the un-magnetized ferromagnetic material, although the internal magnetic tiles have a certain spontaneous magnetization direction and have great magnetism, the magnetization directions of the magnetic tiles are different, so that the ferromagnetic material does not have magnetic properties. When the ferromagnetic material is in an external magnetic field, the volume of the magnetic tiles with a small angle between the spontaneous magnetization direction and the external magnetic field direction is expanded with the increase of the external magnetic field, and the magnetization direction of the magnetic tiles is further turned to the direction of the external magnetic field. The magnetic tiles are mainly used in permanent magnet DC motors. Different from the electromagnetic motor which generates a magnetic potential source through an excitation coil, the permanent magnet motor generates a constant magnetic potential source through a permanent magnet material. The permanent magnet motor has many advantages, such as simple structure, convenient maintenance, light weight, small size, reliable use, less copper, low copper consumption, small energy consumption and the like.

[0003] The grinding machine is a machine tool for grinding the surface of a workpiece using a grinding tool. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use oil stones, abrasive belts, and other grinding tools and free abrasives for processing, such as honing machines, super-precision machine tools, abrasive belt grinding machines, lapping machines, and polishing machines. Grinding machines can process materials with high hardness, such as hardened steel and hard alloy, and can also process brittle materials, such as glass and granite. Grinding machines can perform high-precision and low-surface roughness grinding, and can also perform high-efficiency grinding, such as force grinding. Standard mechanical processing grinding machines and grinding wheel motors operate according to traditional starting circuits. After the motor starts, it operates at the rated speed. Since the voltage of the power grid fluctuates, the grinding wheel and workpiece friction load changes constantly, which will affect the motor speed error. Standard grinding wheel motor starting circuits generally only have one processing speed, which is difficult to adapt to different workpiece size requirements and different processing relative linear speeds, making it difficult to ensure the precision of the processed workpiece. Therefore, from the aspects of improving processing quality, processing efficiency, and energy saving, applying frequency conversion speed regulation technology to grinding machines can achieve satisfactory results. The current main traditional form of magnetic tile shaft length grinding is through type double end surface grinding machine grinding. One piece of magnetic tile workpiece is placed on top of another piece and ground by a grinding wheel. During the conveying process, the reference surfaces of the magnetic tiles are not flat, or the precision of the reference surfaces is relatively unstable, which causes the state of the product entering the grinding wheel to be unstable. If the workpiece is not perpendicular to the grinding wheel, the grinding result will appear to be not perpendicular in four directions. The traditional grinding method cannot meet the requirements of high-precision permanent magnet motor demand high-precision magnetic tile. At the same time, the existing grinding machine structure cannot perform tight conveying operation on the magnetic tile workpiece after grinding, which cannot guarantee the proper protection of the magnetic tile workpiece during the machining of the magnetic tile workpiece, affects the daily processing effect, and is not conducive to daily use. Therefore, it is urgent to design a high-precision shaft length grinding end surface grinding machine to solve the above problems. SUMMARY

[0004] The purpose of the present application is to provide a high-precision shaft length grinding end surface grinding machine to solve the above problems. The current main traditional form of magnetic tile shaft length grinding is through type double end surface grinding machine grinding. One piece of magnetic tile workpiece is placed on top of another piece and ground by a grinding wheel. During the conveying process, the reference surfaces of the magnetic tiles are not flat, or the precision of the reference surfaces is relatively unstable, which causes the state of the product entering the grinding wheel to be unstable. If the workpiece is not perpendicular to the grinding wheel, the grinding result will appear to be not perpendicular in four directions. The traditional grinding method cannot meet the requirements of high-precision permanent magnet motor demand high-precision magnetic tile. At the same time, the existing grinding machine structure cannot perform tight conveying operation on the magnetic tile workpiece after grinding, which cannot guarantee the proper protection of the magnetic tile workpiece during the machining of the magnetic tile workpiece, affects the daily processing effect, and is not conducive to daily use.

[0017] Compared with the prior art, the present application has the following beneficial effects:

[0018] 1. The high-precision end face grinding machine for long shaft grinding, which is characterized by comprising a first motor adjusting frame, a second motor adjusting frame, a first grinding motor, a second grinding motor, a first hydraulic seat, a second hydraulic seat, a grinding wheel body, a feeding frame, a feeding belt, a horizontal linear motion pair, an upper and lower linear motion pair of tooling, a linear motion pair of follow-up pressure block, a cam, a limiting plate, a mounting frame and a conveying steel belt, and is used for efficiently grinding the magnetic shoe workpiece. In actual use, the workman first places the magnetic shoe workpiece to be processed on the feeding belt, and then the magnetic shoe workpiece is input through the feeding belt, enters the feeding frame, is pushed into the feeding waiting area through the horizontal linear motion pair, is pushed into the space between the limiting tooling and the pressure block tooling through the push rod linear motion pair, is lifted upwards into the two grinding wheel bodies through the upper and lower linear motion pairs of tooling and the linear motion pair of follow-up pressure block at both ends of the limiting tooling and the pressure block tooling, is clamped by the limiting tooling and the pressure block tooling, and the chord width side of the grinding product is always perpendicular to the plane of the grinding wheel body, so that the ground product is ensured to be in a vertical state of the shaft length surface and the chord width surface. The product after processing is stably clamped into the clamping sleeve in the fixing frame under the jacking of the upper and lower linear motion pairs of tooling, and is moved along the conveying steel belt. The long shaft grinding machine mainly solves the problem of the verticality of the four sides of the traditional magnetic shoe. Since the product with poor verticality will also affect the form and position tolerance of the product grinding in the subsequent processing, the four corners will be unevenly defective, and the assembly of the motor manufacturer will be affected. The grinding machine ensures that each product is positioned on the inner arc reference surface as the grinding shaft length reference surface, and ensures that each product will not be caused by other reasons to be not perpendicular to the four sides. Batch stable production is realized, the overall processing efficiency of the equipment is improved, the daily processing needs are met, and the practicability of the equipment design is embodied.

[0019] 2. This high-verticality shaft-length grinding lifting end face grinding machine, through the setting of a mounting frame, conveyor steel belt, blocking frame, collection groove, drive motor, drive rod, socket, connecting block, torque shaft, protective rubber pad, shock absorber frame, docking plate, shock absorber spring, and fixing frame, further improves the overall processing efficiency of the equipment. In daily use, after the limit operation ends, when the finished grinding precision shaft-length magnetic tile is pushed into the clamping sleeve, the limit seat can help the fixing frame to be stably fixed at the limit point at the top of the second hydraulic seat. During subsequent pushing, it can quickly avoid the limit. During the fixing, the grinding precision shaft-length magnetic tile can be stably fixed by the fixing block. In addition, during the processing, the fixing frame can be stably fixed by the shock absorber spring. At the same time, the shock absorber frame can be quickly disassembled and assembled by the clamping seat and conveyor steel belt, which meets the daily needs. The system allows for real-time replacement of fixed frames of different sizes to accommodate grinding precision shaft-length magnetic tiles of varying dimensions. Once fixed, the entire shock-absorbing frame can move stably along the conveyor belt driven by the drive motor to one end of the mounting frame. At this point, the socket assembly rotates stably along the drive rod, allowing the ejector block to accumulate power in the internal power-accumulating groove of the power-accumulating frame. The protective rubber pad then retracts stably and is quickly released from the notch in the power-accumulating groove, rapidly striking the docking plate at one end of the shock-absorbing frame. This causes the grinding precision shaft-length magnetic tiles fixed inside the fixed frame to quickly separate and fall into the blocking frame. From there, they enter the storage plate through the collection frame for efficient and stable collection. This effectively protects the processed grinding precision shaft-length magnetic tiles, improving the overall processing quality of the equipment and demonstrating the comprehensiveness of the equipment design.

[0034] Working principle: in use, the user first places the grinding precision shaft length magnetic tile to be processed on the feeding belt 12, and then the grinding precision shaft length magnetic tile is input through the feeding belt 12, enters the feeding frame 11, is pushed into the feeding waiting area through the horizontal swing linear motion pair 13, is pushed into the space between the limiting tool 44 and the pressing tool 45 through the push rod linear motion pair 50, and the upper and lower linear motion pairs 14 on both ends of the limiting tool 44 and the pressing tool 45 and the follow-up pressing block linear motion pair 15 lift the product upwards into the two grinding wheel bodies 9.
