[0025] The steering motor assembly performance testing device includes a frame 1, a speed measuring component 2, a conveying component 3, and a testing component 4 (see Figures 1, 2, and 3 in the instruction manual).

[0026] The testing device also includes a numerical control system, which can issue commands to make each component move as required during operation. Currently available numerical control systems can meet the requirements of this application.

[0027] The frame 1 is equipped with a speed measuring component 2, a conveying component 3, and a detection component 4, which are installed from top to bottom.

[0028] The speed measuring component 2 includes a lifting cylinder 25, a lifting plate 26, and speed measuring probes 27. The lifting plate 26 is mounted on the top of the frame 1 via the lifting cylinder 25. Multiple speed measuring probes 27 are mounted on the lifting plate 26. The speed measuring probes 27 are purchased externally; their brand is Keyence, and their model is LR-X100. When in operation, the speed measuring probes 27 can detect the rotational speed of the workpiece.

[0029] The conveying assembly 3 includes a conveying plate 13, a sliding bracket A7, a sliding bracket B8, a drive sprocket 11, and a transmission chain (see Figures 6, 7, and 8 in the instruction manual).

[0030] Two sets of sliding brackets A7 and sliding brackets B8 are symmetrically mounted on the frame 1 via multiple support slide rods 5 and sliding seats 6; when the sliding brackets A7 and sliding brackets B8 are subjected to force, they can move back and forth along the support slide rods 5.

[0031] The frame 1 is equipped with an adjustment mechanism 17; the adjustment mechanism 17 is connected to the sliding bracket A7 and the sliding bracket B8 (see Figure 8 in the instruction manual).

[0032] The adjustment mechanism 17 includes a drive screw 18, a screw motor 19, a transmission sprocket A20, and a transmission sprocket B21 (see Figures 7 and 8 in the specification).

[0033] The frame 1 is equipped with two sets of drive screws 18; the drive screws 18 are connected to the sliding brackets A7 and B8; the frame 1 is equipped with a transmission sprocket A20 via a screw motor 19; the transmission sprocket A20 is connected to one end of a set of drive screws 18 via a chain; the other end of each of the two sets of drive screws 18 is equipped with a transmission sprocket B21; the transmission sprockets B21 are connected to each other via a chain.

[0034] The purpose of setting up the adjustment mechanism 17 in this way is to enable the lead screw motor 19 to drive a set of drive screws 18 to rotate via the transmission sprocket A20 during operation; and the drive screws 18 to drive another set of drive screws 18 to rotate synchronously via the transmission sprocket B21. In this way, during the rotation of the lead screw motor 19, the drive screws 18 can be driven to rotate forward or in reverse, thereby driving the sliding brackets A7 and B8 to separate or move closer together along the support slide rod 5.

[0035] This allows the steering motor assembly performance testing device to adapt to the testing of various types of workpieces by adjusting the distance between the sliding bracket A7 and the sliding bracket B8.

[0036] A drive shaft 9 with a hexagonal cross-section is mounted on the frame 1 between sliding brackets A7 and B8 via a bearing seat (see Figures 7 and 8 in the instruction manual).

[0037] A drive sprocket 11 is mounted on sliding bracket A7 and sliding bracket B8 via a sliding sleeve 10; the sliding sleeve 10 is slidably connected to the drive shaft 9; a drive chain is mounted on sliding bracket A7 and sliding bracket B8 via the drive sprocket 11 and the driven sprocket 12. During the rotation of the drive shaft 9, the drive chain can be driven to rotate synchronously via the sliding sleeve 10, the drive sprocket 11, and the driven sprocket 12; during the synchronous rotation of the drive chain, the conveyor plate 13 can be moved.

[0038] A conveyor plate 13 (see Figure 6 in the instruction manual) is placed on the drive chain. The drive chain rotates, driving the conveyor plate 13 forward. The conveyor plate 13 has multiple positioning support holes 24. During operation, the workpiece to be inspected can be placed on the positioning support holes 24, so that the conveyor plate 13 moves forward along with the workpiece.

[0039] A drive sprocket 15 is mounted on the frame 1 via a drive motor 14; the drive sprocket 15 is connected to an input sprocket 16 at one end of the drive shaft 9 via a drive chain (see Figures 7 and 8 in the instruction manual). During operation, the drive motor 14 drives the drive shaft 9 to rotate synchronously via the drive sprocket 15 and the input sprocket 16. During the rotation of the drive shaft 9, the conveyor plate 13 can ultimately be moved via the drive chain.

[0040] Multiple limiting pins 23 are mounted on the frame 1 between sliding brackets A7 and B8 via positioning cylinders 22 (see attached figure 6 in the instruction manual). During operation, when the transmission chain drives the conveyor plate 13 to move below the speed measuring component 2, the positioning cylinders 22 drive the limiting pins 23 to move upward, thereby limiting the conveyor plate 13 from both ends; thus, the conveyor plate 13 is positioned.

[0041] The detection component 4 includes a lifting cylinder 28, a lifting plate 29, and detection plugs 30. The lifting cylinder 28 at the bottom of the frame 1 is equipped with the lifting plate 29. Multiple detection plugs 30 are mounted on the lifting plate 29 (see attached Figure 9 in the manual). The detection plugs 30 are connected to an external resistance tester; the resistance tester is an externally purchased device, model TH2518. During operation, when the lifting plate 29 pushes the detection plug 30 to connect with the workpiece, the resistance tester can test the resistance of the workpiece, thus achieving the detection purpose.

[0042] When the steering motor assembly performance testing device is working, the drive motor 14 first drives the transmission shaft 9 to rotate synchronously through the drive sprocket 15 and the input sprocket 16. During the rotation of the transmission shaft 9, the conveyor plate 13 can eventually be moved through the transmission chain. When the conveyor plate 13 moves the workpiece to below the speed measuring component 2, the transmission chain stops moving; at this time, the positioning cylinder 22 drives the limiting pin 23 to move upward, so that it limits the workpiece from both ends of the conveyor plate 13.

[0043] After the conveyor plate 13 moves to the designated position, the lifting cylinder 28, through the lifting plate 29, drives the detection plug 30 upward to connect with the workpiece. Once the workpiece is connected to the detection plug 30, it will begin operation. During work, the lifting cylinder 25, through the lifting plate 26, drives the speed measuring probe 27 downward to complete the workpiece speed measurement. Simultaneously, the resistance tester, with the cooperation of the detection plug 30, can complete the resistance test.

[0044] After the test is completed, the detection component 4 is reset, the speed measuring component 2 is reset, and the limiting pin 23 is reset; then the transmission chain drives the conveyor plate 13 to move the tested workpiece to the next station; the subsequent conveyor plate 13 moves the workpiece to be tested to below the speed measuring component 2, and the steering motor assembly performance testing device can enter the next working cycle.

[0045] This steering motor assembly performance testing device has a compact structure and ingenious design, and can mechanize the performance testing of the steering motor assembly. This solves the problem of low testing efficiency in existing steering motor assembly performance testing methods, and is particularly suitable for testing the performance of steering motor assemblies.
