Description

Technical Field

[0001] The invention relates to the technical field of wear-resistant detection devices, in particular to a device for detecting the working state of a wear-resistant coating of an electromagnetic brake. Background Art

[0002] The wear-resistant coating on the electromagnetic brake is a key component to ensure the braking performance, durability and reliability of the electromagnetic brake. It is mainly used to reduce the wear of the friction pair, such as the brake disc, improve thermal stability, and prevent brake failure caused by the degradation of the friction material. The wear-resistant coating of the electromagnetic brake needs to select materials and processes according to the specific working conditions (load, temperature, environment). Testing friction performance and preventive maintenance are the key to ensuring its long-term stable operation. Therefore, the wear resistance measurement of the brake disc surface coating is particularly important.

[0003] However, when the existing electromagnetic brake wear-resistant coating working status detection device tests the wear resistance of the brake disc surface coating, the wear-resistant coating is generally applied to the test piece, and then the surface of the test piece coated with the wear-resistant coating is rubbed. The degree of wear of the coating is tested by the instrument to obtain the wear resistance data of the coating. On the one hand, dust is generated when the surface of the test piece is rubbed, and the dust will adhere to the surface of the test piece, which is inconvenient to clean and is not conducive to the subsequent measurement of the wear resistance of the coating. On the other hand, due to the different sizes of the test pieces, the range of dust adhesion is increased, which is inconvenient for centralized dust cleaning of the test pieces.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original electromagnetic brake wear-resistant coating working status detection device. Summary of the Invention

While the test piece is clamped, the first electric push rod drives the interference rod 671 to move downward until the clamping block 673 is disengaged from the clamping groove 7 in the middle of the first rotating disk 51. Then the driving motor drives the sleeve 63 to continue rotating, and cooperates with the friction plate to grind the surface of the test piece;

[0036] After the grinding is completed, the screw lift 2 drives the cover 3 to rise, and then removes the friction plate, and then drives the cover 3 to descend through the screw lift 2 until the flexible brush 56 is in contact with the surface of the test piece. When the telescopic arm 54 contracts inward, the telescopic arm 54 resists the first piston rod 572 and slides into the first oil tank 571.

Under the action of the spring, the second piston rod 574 contracts into the second oil tank 573 and drives the second electric push rod 575 to move backward. Then the controller 8 controls the second electric push rod 575 to push the mounting block to move, and the movement of the mounting block drives the rotating cleaning plate 576 to move along the accommodating block 5 5 rotates to a certain angle, and then drives the motor to drive the second pulley 62 to rotate, the second pulley 62 drives the first pulley 61 to rotate, the first pulley 61 drives the sleeve 63 to rotate, the sleeve 63 drives the clamping plate 4 to rotate, the clamping plate 4 drives the test piece to rotate, so that the flexible brush 56 cleans the surface of the test piece, cooperates with the rotating cleaning plate 576 rotated to a certain angle, so that dust gradually gathers around the periphery of the test piece, cooperates with the negative pressure suction device to suck out the dust on the surface of the test piece, and finally drives the screw lift 2 to drive the cover 3 to rise, and drives the clamping block 66 to unfold through the driving motor, removes the test piece for testing, and judges the wear resistance.
