Description

Technical Field

[0001] The present invention relates to the technical field of wear-resistant detection devices, and particularly to a detection device for the working state of a wear-resistant coating of an electromagnetic brake. Background Technique

[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 friction pairs, such as brake discs, improve thermal stability, and prevent braking failure caused by the degradation of friction materials. The wear-resistant coating of the electromagnetic brake needs to select materials and processes according to specific working conditions (load, temperature, environment). Detecting friction performance and preventive maintenance are the keys to ensuring its long-term stable operation. Therefore, it is particularly important to determine the wear resistance of the surface coating of the brake disc; However, when the existing detection device for the working state of the wear-resistant coating of the electromagnetic brake tests the wear resistance of the surface coating of the brake disc, generally, the wear-resistant coating is coated on the test piece, and then the surface of the test piece coated with the wear-resistant coating is rubbed, and the wear degree of the coating is tested by an instrument to obtain the wear resistance data of the coating. On the one hand, dust will be generated when rubbing the surface of the test piece, and these dusts will adhere to the surface of the test piece, which is inconvenient to clean and is not conducive to the subsequent determination of the wear resistance of the coating. On the other hand, due to the different sizes of the test pieces, the range where the dust will adhere increases, and it is not convenient to centrally clean the dust of the test pieces.

[0003] In view of the above problems, it is urgent to innovate and design on the basis of the original detection device for the working state of the wear-resistant coating of the electromagnetic brake. Summary of the Invention

The first oil tank 571 and the second oil tank 573 have the same volume. When the telescopic arm 54 contracts inwardly, the telescopic arm 54 resists the first piston rod 572 and slides into the first oil tank 571. The oil in the second oil tank 573 flows into the first oil tank 571 through the hose. Under the action of the spring, the second piston rod 574 contracts into the second oil tank 573, driving the second electric push rod 575 to move backward. Subsequently, the controller 8 controls the second electric push rod 575 to push the mounting block to move.

[0023] Working principle: When using the electromagnetic brake wear-resistant coating working status detection device, first place the test piece with the wear-resistant coating on the surface on the clamping fixed disk 4, and install the friction plate adapted to the test piece under the accommodating block 55 through the pneumatic mounting rod, and then control the screw lift 2 through the controller 8 to drive the cover body 3 to move downward until the clamping fixed disk 4 is covered, and then the first electric push rod pushes the contact rod 671 to move upward until the clamping block 673 at the top of the contact rod 671 is clamped into the clamping groove 7 in the middle of the first rotating disk 51, and the driving motor drives the second pulley 62 to rotate, and the rotation of the second pulley 62 drives the first pulley 61 to rotate, and the first pulley 61 rotates The sleeve 63 is driven to rotate, and the rotation of the sleeve 63 drives the resistance rod 671 to rotate. The rotation of the resistance rod 671 and the sleeve 63 drives the first rotating disk 51 and the second rotating disk 64 to rotate synchronously, and cooperates with the limiting disk 53 and the limiting groove on the top of the clamping fixed disk 4 to make the clamping block 66 and the telescopic arm 54 retract inward until the test piece is clamped. At this time, the telescopic arm 54 retracts inward to make the diameter of the flexible brush 56 and the test piece the same. While the test piece is clamped, the first electric push rod drives the resistance 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, and then the driving motor drives the sleeve 63 to continue to rotate, and cooperates with the friction plate to grind the surface of the test piece; 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 fits 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. The oil in the second oil tank 573 flows into the first oil tank 571 through the hose. 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 installation block to move, and the movement of the installation 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 rotates to drive the first pulley 61 to rotate, the first pulley 61 rotates to drive the sleeve 63 to rotate, the sleeve 63 rotates to drive the clamping plate 4 to rotate, the clamping plate 4 rotates to drive 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 lifter 2 to drive the cover body 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.
