At this time, the end piece proximity switch 213 detects that the end piece 801 has arrived in place, and the end piece spacer lifting cylinder 205 drives the end piece spacer translation cylinder 206 and the end piece spacer block 204 to move downward together. At the same time, the end piece material taking cylinder 208 drives the end piece loading cylinder 2 10 and the end piece loading stepper motor 211 make a straight line movement toward the end piece straight vibration channel 202, until the end piece loading stepper motor 211 moves to the front of the end piece spacer block 204, and then the end piece spacer translation cylinder 206206 drives the end piece pushing block 207 to move toward the end piece spacer block 204, and then the end piece 801 in the end piece spacer block 204 is pushed out of the end piece spacer block 204 and installed on the end piece positioning column 212 at the output end of the end piece loading stepper motor 211, and then the end piece is taken out.

[0151] When the end piece 801 is loaded onto the fixture 105 of the end piece fixing station 101, the turntable 106 is driven to rotate by the servo motor 107 of the feeding mechanism and the harmonic reducer 108, thereby rotating the fixture 105 with the end piece 801 to the end piece height detection station 102, thereby conveying the end piece 801 to the end piece height detection station 102;

[0152] After the end piece 801 is transported to the end piece height detection station 102, the height detection cylinder 302 drives the height detection probe 305 to move downward until the height detection probe 305 and the end piece 801 (the end piece 801 can be a square end piece or a round end piece, Figure 9 In this process, the height detection electronic ruler 304 detects the moving distance of the height detection probe 305 and transmits the detection value to the control system. It is compared with the standard value preset in the control system to determine whether the plane height of the detection end piece 801 is qualified, thereby completing the height detection of the end piece 801;

[0153] c) The end piece 801 after height detection is transported to the assembly station 103 by the rotary feeding mechanism 1, and the end piece 801 transported to the assembly station 103 is clamped and positioned by the assembly clamping and positioning mechanism 5, specifically:

[0154] After the height of the end piece 801 is detected, the end piece height detection mechanism 3 returns to its original position, and the turntable 106 is driven to rotate by the servo motor 107 and the harmonic reducer 108 of the feeding mechanism, and the fixture 105 with the end piece 801 of qualified height is rotated to the assembly station 103, thereby transporting the end piece 801 to the assembly station 103 ( Figure 10 The position of the middle end piece 801 is the position of the assembly station 103);

[0155] After the end piece 801 is transported to the assembly station 103, the positioning fixture 501 is driven by the clamping positioning translation cylinder 502 to move toward the assembly station 103 until the end piece 801 on the fixture 105 of the assembly station 103 is accommodated in the positioning groove 5011 of the positioning fixture 501. Then, the movable guide block 504 is driven by the guide block translation cylinder 505 to move to the positioning groove 5011. The end piece 801 in the positioning groove 5011 is clamped by the movable guide block 504 and the fixed guide block 503. In this way, the clamping and positioning of the end piece 801 is achieved.

[0156] d) The rod 802 of the automobile brake joint 8 to be assembled is loaded onto the spinning mechanism 6 through the rod loading mechanism 4, specifically:

[0157] The rod 802 of the automobile brake joint 8 to be assembled is placed on the rod vibration plate 401, and then under the action of the rod straight vibration material channel 402 and the rod straight vibrator 403, the rod 802 is sequentially transported to the rod spacer block 404 at the outlet end of the rod straight vibration material channel 402. At this time, the rod proximity switch 410 detects that the rod 802 is in place, and then the rod spacer translation cylinder 405 drives the rod spacer block 404 to move in a straight line toward the rod picking mechanical claw 407. When the rod spacer block 404 brings the rod 802 to the front of the rod picking mechanical claw 407, the rod picking cylinder 406 drives the rod picking mechanical claw 4 07 moves to the rod 802 to grab the rod 802. After the rod 802 is grabbed, the rod spacer translation cylinder 405 drives the rod spacer block 404 to return to its original position. Then the rod loading translation cylinder 409 drives the rod loading lifting cylinder 408 and the rod picking mechanical claw 407 to move toward the spinning mechanism 6 until the rod 802 is located directly below the spinning mechanism 6. Then the rod loading lifting cylinder 408 drives the rod picking mechanical claw 407 to move vertically upward, thereby installing the rod 802 on the rod picking mechanical claw 407 onto the spring chuck 612 of the spinning mechanism 6, thereby realizing the loading of the rod 802.

[0158] e) The rod 802 is spun into the end piece 801 by the spinning mechanism 6 to assemble the automobile brake joint 8, specifically:

[0159] When the rod 802 is loaded onto the spring chuck 612, the rod loading mechanism 4 returns to its original position, and the spinning servo motor 614 and the electric cylinder 613 drive the spinning guide shaft 607, the limit block 608, the screw 609, the nut 610, the chuck 611, the spring chuck 612 and the rod 802 to move vertically downward. When the rod 802 contacts the end piece 801 on the assembly clamping positioning mechanism 5, the screw 609, the nut 610, the chuck 611, the spring chuck 612 and the rod 802 are subjected to resistance. At this time, the limit block 608 on the spinning guide shaft 607 reaches the limit, and the spinning guide shaft 607, the limit block 608 and the guide assembly 607 that are the same as the spinning guide shaft 607 are connected to the guide assembly 601. The nuts 610 fixedly connected to the mounting plate 603 cannot move downward, while the output end 6131 of the electric cylinder 613 can continue to move downward. Since there is a threaded relationship between the screw 609 and the nut 610, the screw 609 can rotate and move downward through the threaded action between it and the nut 610, thereby driving the spring clamp 612 and the rod 802 to rotate and move downward together, and then spinning the rod 802 into the end piece 801 to assemble the automobile brake joint 8; the spinning assembly adopted in this step of the present invention can not only realize the automatic spinning assembly of the automobile brake joint 8, but also, compared with the traditional stamping assembly, can make the assembly process without eccentricity, uniform force, and better assembly quality;

[0160] f) The assembled automobile brake joint 8 is transported to the unloading station 104 by the rotating feeding mechanism 1, and the assembled automobile brake joint 8 is unloaded by the unloading mechanism 7, specifically:

[0161] After the spinning assembly is completed, the assembly clamping and positioning mechanism 5 and the spinning mechanism 6 return to their original positions, and the turntable 106 is driven to rotate by the servo motor 107 of the feeding mechanism and the harmonic reducer 108, so as to rotate the fixture 105 holding the automobile brake connector 8 to the unloading station 104, thereby conveying the assembled automobile brake connector 8 to the unloading station 104;

[0162] After the assembled automobile brake joint 8 is transported to the unloading station 104, the unloading mechanical claw 706 is controlled to move horizontally by the unloading translation mechanism 703, and the unloading mechanical claw 706 is controlled to move up and down by the unloading lifting cylinder 704, so that the unloading mechanical claw 706 is moved to the unloading station 104, and then the unloading mechanical claw 706 can grab the assembled automobile brake joint 8. After the unloading mechanical claw 706 grabs the automobile brake joint 8, the unloading mechanical claw 706 is rotated by the unloading rotating cylinder 705, and then the position of the automobile brake joint 8 is adjusted, so that the automobile brake joint 8 is placed on the unloading straight vibrating material channel 701, and then the automobile brake joint 8 can be sent out through the unloading straight vibrating material channel 701 and the unloading straight vibrator 702 to enter the subsequent process, thereby completing the unloading of the automobile brake joint 8;

[0163] From the above, it can be seen that through the device described in the present invention, it is possible to realize automatic loading of the end piece 801 and the rod piece 802, automatic detection of the plane height of the end piece 801, automatic spinning and assembly of the rod piece 802 into the end piece 801 to assemble it into the automobile brake joint 8, and automatic unloading of the assembled automobile brake joint 8. This shows that the present invention can realize the fully automatic assembly operation of the automobile brake joint, which can significantly improve the assembly efficiency and assembly quality of the automobile brake joint, and has significant progressiveness and industrial application value.

[0164] Finally, it is necessary to point out here that the above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered within the scope of protection of the present invention.
