[0018] Reference Figure 1The storage rack assembly 3 includes two first rails 31, and the two first rails 31 are connected to the top of the rack 1 through supporting columns. Two side baffles 35 are arranged on the top of the two first rails 31. The two side baffles 35 are slidably sleeved on the two first rails 31 through two second sliders 34 and two first sliders 32 respectively. The two first sliders 32 and the second sliders 34 are connected through two placement rods 33 respectively. A plurality of semi-axis detection components 4 are placed on the two placement rods 33. The two first rails 31 have a height difference, and the height of a first rail 31 approaching the automatic material lifting platform 2 is lower than the height of the other first rail 31. The tops of the two first sliders 32 can be used to place a plurality of semi-axis detection components 4. The connection relationship between the first slider 32, the second slider 34 and the two first rails 31 can adjust the spacing between the two placement rods 33 and the two side baffles 35 according to the length of the semi-axis detection component 4. The height difference between the two first rails 31 can make the stored plurality of semi-axis detection components 4 naturally roll toward the automatic material lifting platform 2.

[0019] Reference Figure 2 The automatic lifting platform 2 includes a bottom fixing plate 21, a static plate 22 is fixedly installed on the top of the bottom fixing plate 21, the bottom fixing plate 21 is fixedly installed inside the platform 1, a first rail groove is provided on the top of the static plate 22, and two first support blocks 27 are fixedly installed in the first rail groove, a clamping mechanism 5, a detection mechanism 6, and a positioning mechanism 7 are installed on the top of the static plate 22, two second rails 23 are fixedly connected to the front of the bottom fixing plate 21, and the two second rails 23 are slidably connected with a moving plate 25 through two third sliders 24 respectively, an electric cylinder 26 is provided on the front of the moving plate 25, and the electric cylinder 26 is fixedly installed in the platform 1, and the output end of the electric cylinder 26 is fixedly installed on the front of the moving plate 25, a second rail groove is provided on the top of the moving plate 25, and two second support blocks 28 are fixedly installed in the second rail groove, and the tops of the first support blocks 27 and the second support blocks 28 are both sloped surfaces, The top slope of the first support block 27 cooperates with the top slope of the second support block 28 to form a V-shaped groove. When the semi-axle detection part 4 stored in the storage rack assembly 3 slides toward the automatic lifting platform 2, it contacts the front of the movable plate 25 and is blocked by the movable plate 25. Then, the movable plate 25 is driven downward by the output of the electric cylinder 26. At this time, the third slider 24 slides on the second track 23. When the movable plate 25 moves down to below the height of the semi-axle detection part 4, the semi-axle detection part 4 in contact with the front of the movable plate 25 naturally rolls to the top of the two second support blocks 28 and is blocked by the static plate 22. The output shaft of the electric cylinder 26 extends to drive the movable plate 25 to move up and restore the position. At this time, the semi-axle detection part 4 located at the top of the second support block 28 rolls into the V-shaped groove formed by the slopes of the first support block 27 and the second support block 28, thereby completing the extraction of a single semi-axle detection part 4.

[0020] Reference Figure 2The positioning mechanism 7 includes a first material level sensor 71, a second material level sensor 72, and a side push cylinder 73. The first material level sensor 71 is fixedly installed in the first rail groove at the top of the static plate 22.

The second material level sensor 72 is fixedly installed in the first rail groove at the top of the static plate 22. The side push cylinder 73 is located at the other end of the top of the static plate 22. The side push cylinder 73 is fixedly installed at the top of the static plate 22. The first material level sensor 71 and the second material level sensor 72 are electrically connected to the PLC controller, and the PLC controller is electrically connected to the side push cylinder 73 through the solenoid valve. When a single semi-axle detection part 4 is extracted to the top of the automatic lifting platform 2, the first material level sensor 71 detects that there is material and sends a signal to the PLC controller. The PLC controller controls the output of the side push cylinder 73 to push the semi-axle detection part 4 on the top of the automatic lifting platform 2 to move. When the second material level sensor 72 detects the end face of the semi-axle detection part 4, it reaches the detection position of the detection mechanism 6 and sends a signal to the PLC controller. The PLC controller controls the side push cylinder 73 to retract to complete the positioning of the semi-axle detection part 4. The models of the first material level sensor 71 and the second material level sensor 72 are: CR18-8DN.

[0021] Reference Figure 2 The clamping mechanism 5 includes a second angle cylinder 51, a second connecting frame 52 is fixedly installed on the output shaft of the second angle cylinder 51, a pressing block 53 is fixedly installed on the bottom of the second connecting frame 52, and the second angle cylinder 51 is installed in the first rail groove on the top of the static plate 22 through the second fixed plate 54. After the half-axis detection part 4 moves to the detection position, the second connecting frame 52 can be driven by the second angle cylinder 51 to move, so that the pressing block 53 presses and fixes the half-axis detection part 4. The model of the second angle cylinder 51 is: ACKL63X180.

[0022] Reference Figure 3 The static plate 22 includes a horizontal plate 221 and a vertical plate 222. The first rail groove is set at the top of the vertical plate 222. The bottom fixed plate 21 is installed at the bottom of the horizontal plate 221. The horizontal plate 221 and the vertical plate 222 are connected by hinges. Two first connecting members 223 are fixedly installed on the top of the horizontal plate 221, and two second connecting members 224 are fixedly connected to the back of the vertical plate 222. The two first connecting members 223 and the second connecting members 224 are movably connected through a telescopic rod 225. The angle between the horizontal plate 221 and the vertical plate 222 can be adjusted by cooperating with the first connecting member 223, the second connecting member 224 and the telescopic rod 225, so as to ensure that the static plate 22 and the moving plate 25 can be in a parallel state.

[0023] The working principle of the utility model is as follows: the semi-axle detection part 4 is stored by the storage rack assembly 3, so that the semi-axle detection part 4 can slide toward the automatic lifting platform 2. When the automatic lifting platform 2 is running, a single semi-axle detection part 4 inside the storage rack assembly 3 can be brought out to the top of the automatic lifting platform 2. After the semi-axle detection part 4 on the top of the automatic lifting platform 2 is detected by the positioning mechanism 7, it can be automatically positioned and pushed to the detection position. Thereafter, the semi-axle detection part 4 is pressed and fixed by the clamping mechanism 5, and then the first connecting frame 62 is driven to move by the first corner cylinder 61, thereby driving the displacement sensor 63 to the set detection position through the first connecting frame 62, and the distance data value from the detection end of the displacement sensor 63 to the side wall of the semi-axle detection part 4 is measured by the displacement sensor 63. When the detection data value meets the set data value, the direction of the processing end of the semi-axle detection part 4 is correct. Since the diameters of the processing end and the non-processing end of the semi-axle detection part 4 are different, when the displacement sensor 63 detects that the distance value to the side wall of the semi-axle detection part 4 does not match the set value, it can be determined that the direction of the semi-axle detection part 4 is wrong.
