Description

Technical Field

[0001] This invention belongs to the field of flaw detection equipment technology, and in particular relates to a magnetic flux leakage flaw detection carbon brush slide repair and grinding device. Background Technology

[0002] The silver bright material magnetic flux leakage flaw detection equipment works by using a belt motor to drive the magnetic flux leakage rotating host. The working voltage of the magnetic flux leakage yoke is transmitted to the carbon brush disk through carbon brushes. Due to the need for high-speed rotation for a long time during normal production, the carbon brushes and carbon brush disk slides will wear out very severely. If the carbon powder adhering to the carbon brush slides is not cleaned in time, it is very easy to cause phase-to-phase short circuits, thereby damaging the magnetic yoke and the magnetic flux leakage power module, causing equipment accidents and affecting the production rhythm.

[0003] Because the contact and friction positions of the carbon brushes in the slide are inconsistent during equipment operation, the surface of the carbon brush disk slide will be uneven, and the carbon brushes are also prone to breakage or damage. Therefore, during shutdown maintenance, a lot of manual time is often required to grind and repair the slide of the carbon brush disk to ensure that the slide of the flaw detector is smooth and burr-free, and that the inside of the slide is clean and free of foreign matter.

[0004] Manual maintenance and repair methods are not reasonable and effective in repairing the slide rail. Not only will they greatly increase the daily workload of the staff, thus reducing the working efficiency of the flaw detection equipment, but also, because the skill level of each person is different when grinding by hand, it is easy to cause uneven grinding of the slide rail, which will cause secondary wear of the slide rail.

[0005] Therefore, there is an urgent need to design a magnetic flux leakage testing carbon brush slide repair and grinding device to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a grinding and repair device for carbon brush slides in magnetic flux leakage testing. The device features a centering frame design that ensures the shaft and the steel inlet on the main unit are concentrically distributed. A large gear and drive motor design drive the rotation of the shaft, swing arm, and repair rod. An adjustable clamping spring design ensures sufficient clamping force between the repair rod and the carbon brush slide. A grooved design allows adjustment of the carbon brush slide corresponding to the repair rod. This enables semi-automated, high-efficiency grinding and repair, improving both repair efficiency and effectiveness.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a magnetic flux leakage testing carbon brush slide repair and grinding device, comprising a fixed frame, a centering frame, a shaft, a repair rod, and a drive motor; The centering frame includes a tapered sleeve, and one end of the shaft is fixed concentrically to the large end of the tapered sleeve via a connecting frame.

The large gear is fixed with a swing arm at the end away from the adjustable clamping spring. The swing arm is perpendicular to the shaft and has a strip groove at the end away from the shaft. One end of the repair rod is fixed to the strip groove by a fastening bolt. The repair rod is distributed parallel to the shaft and the bottom end is fixed with a grinding block by a fastener.

[0008] Furthermore, it also includes a flaw detection rotary host, one surface of which is provided with a steel passage, a carbon brush slide, and three positioning screws. The steel passage is concentric with the carbon brush slide, and the three positioning screws are arranged in a ring at even intervals on the outside of the carbon brush slide.

[0009] Furthermore, the small end gap of the conical sleeve is set at the inner end of the steel passage, the lugs of the three connecting legs are respectively fixed at the three positioning screws, and the grinding block is set in the carbon brush slide.

[0010] Furthermore, the adjustable compression spring includes a spring body and a screw. One end of the spring body is fixed to the end face of the shaft, and a sliding sleeve is fixed to the other end of the spring body. The screw is fixed to the centering plate and is concentrically arranged inside the spring body. A nut is threaded onto the screw, and the sliding sleeve slides along the screw and contacts the nut.

[0011] Furthermore, the connecting frame includes an annular portion, the end of the shaft is fixed concentrically with the annular portion, and the peripheral side of the annular portion is provided with three strip-shaped support plates, the end of the support plate away from the annular portion is fixed to the large end face of the conical sleeve.

[0012] Furthermore, the connecting legs are perpendicular to the connecting rod, and a reinforcing rib is provided between the connecting rod and the connecting legs.

[0013] The present invention has the following beneficial effects: 1. This invention, through the design of the center frame, ensures that the shaft and the steel passage on the main unit are concentrically distributed. Through the design of the large gear and drive motor, it can drive the rotational movement of the shaft, swing arm and repair rod. Through the design of the adjustable clamping spring, it can ensure the clamping force between the repair rod and the carbon brush slide, ensuring the repair grinding effect. Through the design of the strip groove, it can adjust the carbon brush slide corresponding to the repair rod, increasing the repair range. It can realize semi-automated high-efficiency grinding and repair, improve the repair efficiency and effect, and ensure the use effect of the subsequent flaw detection main unit.

[0014] 2. This invention enables the fixed frame to be positioned and installed by designing three connecting rods and connecting legs on the fixed frame. At the same time, the connection point is the original positioning screw on the main unit, so there is no need to set up a separate installation point, which is convenient for installation and disassembly and for the operation of the staff.
