[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0023] Example:

Air gap testing includes testing the air gap between the armature and the stationary plate, the air gap between the brake disc and the friction plate, and the air gap between the coil and the iron core shell. The air gap testing involved in the scheme described below is the air gap testing between the coil and the iron core shell. Since the coil is set on the winding frame, the air gap testing is the testing of the air gap between the winding frame 14 and the iron core (see...). Figure 5 ).

[0025] See Figure 1-4 An electromagnetic brake performance testing device includes a workbench 1, on which an air gap detection device 9, a positioning fixture 3, and an electrical conduction testing device are mounted. A rotary drive assembly is also mounted on the workbench 1. The rotary drive assembly controls the positioning fixture 3 to rotate so that all air gaps to be tested on the workpiece 13 within the positioning fixture 3 pass through the detection end of the air gap detection device 9. A terminal connector 1 that rotates with the positioning fixture 3 is mounted on the workbench 1. A wire harness terminal capable of connecting to the terminal connector 1 is present on the workpiece 13. The terminal connector 1 is electrically connected to the electrical conduction testing device, thereby enabling the electrical conduction testing device to test the electrical conduction performance of the workpiece 13.

[0026] The workbench 1 is equipped with a turntable 2, the positioning fixture 3 is mounted on the turntable 2, and the drive end of the rotary drive assembly 8 is connected to the turntable 2. The rotary drive assembly can be a servo motor. Specifically, the turntable 2 is fixed to the upper half of a hollow tubular rotating connector 12, the lower half of the rotating connector 12 is fixed to the inner ring of a bearing 11, and the outer ring of the bearing 11 is fixed to the workbench 1. At the same time, a hollow pulley 10 is also fixed to the inner ring of the bearing 11. The rotary drive assembly drives the pulley 10 to move through the belt, thereby causing the turntable 2 to rotate.

[0027] The turntable 2 is provided with a clamping component 7 for fixing the workpiece 13 in the positioning fixture 3. The clamping component 7 can be a pencil-shaped cylinder, which is set above the worktable 1 and fixed on a connecting frame above the worktable 1.

[0028] The air gap detection device 9 is located below the workbench 1. Specifically, it is an air gap detection device 9 that uses laser to detect air gaps. The workbench 1, turntable 2, and positioning fixture 3 all have clearance holes. The air gap of the workpiece 13 is the air gap between the winding and the outer shell of the iron core. The air gap passes through the clearance holes so that the air gap detection equipment can detect it. In this solution, the outer ring of the bearing 11 is fixed in the clearance hole on the workbench 1. The air gap detection equipment passes through the hollow part of the rotating connector 12 through the workbench 1 and the turntable 2, and detects the air gap of the workpiece 13 after passing through the clearance hole on the positioning fixture 3.

[0029] The terminal connector is connected to the power-on detection equipment via an electric wire, and the workbench 1 is equipped with a wire winding and unwinding device, which winds up and unwinds the wire according to the rotation direction of the turntable 2.

[0030] The take-up and unwinding device includes an electric slip ring take-up reel 6 and a take-up and unwinding drive device. The power-on detection device is connected to the stationary part of the electric slip ring on the electric slip ring take-up reel 6 via a wire 1. The terminal connector 1 is connected to the rotor part on the electric slip ring take-up reel 6 via a wire 2 after winding around it.

[0031] The take-up and unwind drive device includes a gear ring 4 that meshes with each other and is mounted on a turntable 2, and a gear 5 that is mounted on the take-up and unwind device. The gear 5 is rotatably connected to a connecting shaft, and the take-up reel 6 is fixed above the gear 5.

[0032] The turntable 2 is also equipped with a wire clamp 16, which is used to clamp and fix one end of the wire connection terminal connector.

[0033] The workbench 1 is also equipped with a resistance testing device, a terminal connector 2, and a wire clamp 2 17. The resistance testing device is connected to the terminal connector 2 via a wire 3, and the wire clamp 2 17 is used to clamp and fix one end of the wire 3 connected to the terminal connector.

[0034] The workbench 1 is also equipped with a voltage resistance testing device 18 for testing the voltage resistance capability of the iron core shell. An opening is provided on the positioning fixture 3 for the testing head of the voltage resistance testing device 18 to contact the outer wall of the iron core shell.

[0035] Working principle and process:

[0036] This solution controls the rotation of the workpiece 13 positioning fixture 3 by a rotary drive component, so that the air gap on the workpiece 13 passes through the air gap detection device 9. At the same time, the power-on detection device is powered on the workpiece 13, which can complete the power-on detection and air gap detection at the same time, thereby shortening the detection time and effectively improving the detection efficiency.

[0037] At the same time, after power-on testing, resistance testing and voltage withstand testing can be performed simultaneously, further improving testing efficiency.
