[0019] The stabilizer bar placement rack 2 is arranged on the workbench 1 to place the stabilizer bar 10. In the present embodiment, the stabilizer bar placement rack 2 includes a pair of brackets 21, each bracket 21 includes a bracket body 21a and a guide arm 21b, the bracket body 21a is fixed to the workbench 1, a V-shaped groove 210 is provided on the top of the bracket body 21a, the bottom end of the guide arm 21b is connected to the bracket body 21a, and the top surface 211 of the guide arm 21b intersects with one of the side walls 212 of the V-shaped groove 210, and the two together act as a stabilizer bar slideway to guide the stabilizer bar 10 to fall into the V-shaped groove 210.

[0020] Identify the first side of the tooling 4 and the tooling driving mechanism 5 close to the stabilizer bar placement rack 2 ( Figure 1 The left side of the tooling 4 is movably arranged on the workbench 1, and an orientation groove 41 is provided at one end of the tooling 4 close to the stabilizer bar placement rack 2. In this embodiment, a first slide rail 11 is provided on the top of the workbench 1. The orientation tooling 4 includes a tooling body 4a and a tooling base 4b, and the orientation groove 41 is provided at one end of the tooling body 4a close to the stabilizer bar placement rack 2; the top of the tooling base 4b is connected to the tooling body 4a, and the bottom of the tooling base 4b is provided with a first slider 411 that slidably cooperates with the first slide rail 11.

[0021] The tooling driving mechanism 5 is used to drive the direction recognition tooling 4 to move between the initial position and the working position. When the direction recognition tooling 4 is in the working position, the direction recognition groove 41 can accommodate the end of the stabilizing rod rotated to a predetermined angle. In this embodiment, the tooling driving mechanism 5 is a tooling driving cylinder, and the push rod 51 of the tooling driving cylinder 5 is connected to the direction recognition tooling 5. Among them, the free end of the push rod 51 is connected with a connecting disc 512, the connecting disc 512 is coaxial with the central axis of the push rod 51, and the diameter of the connecting disc 512 is greater than the diameter of the push rod 51. The end of the direction recognition tooling 4 close to the tooling driving mechanism 5 is provided with a connecting groove 412, and the two ends of the connecting groove 412 respectively pass through the two sides of the direction recognition tooling 4, and the connecting disc 512 is embedded in the connecting groove 412 to realize the connection between the push rod 51 and the direction recognition tooling 5.

[0022] The mounting frame 3, the stabilizer bar gripper 6, the gripper rotating mechanism 7 and the pushing mechanism 8 are close to the second side of the stabilizer bar placement frame 1 ( Figure 1 ), the second side is an opposite side to the first side.

[0023] The mounting frame 3 is movably disposed on the workbench 1. In this embodiment, a second slide rail 12 is disposed on the top of the workbench 1; and a second slider 32 slidably matched with the second slide rail 12 is disposed on the bottom of the mounting frame 3.

[0024] The gripper rotating mechanism 7 is mounted on the mounting frame 3, and the gripper rotating mechanism 7 is connected to the stabilizer bar gripper 6 to drive the stabilizer bar gripper 6 to rotate, and the stabilizer bar gripper 6 is used to clamp the stabilizer bar 10. In this embodiment, the gripper rotating mechanism 7 is a servo motor. The stabilizer bar gripper 6 is a pneumatic gripper. The stabilizer bar gripper 6 has a pair of clamping claws 61 and a connecting shaft 62, and the stabilizer bar gripper 6 is key-connected to the output end of the servo motor 7 through the connecting shaft 62.

[0025] The pushing mechanism 8 is used to push the mounting frame 3 to move toward the second side of the stabilizing rod placement frame. In this embodiment, the pushing mechanism 8 is composed of a pushing cylinder, and a push rod 81 of the pushing cylinder 8 is connected to the mounting frame 3. In some specific embodiments, the free end of the push rod 81 is provided with an external thread, and the mounting frame 3 is provided with a threaded hole, and the push rod 81 is spirally connected to the threaded hole.

[0026] Furthermore, the stabilizing rod end recognition device further comprises a pressing rod mechanism, which is fixed to the workbench 1 and is used to press the rod body of the stabilizing rod 10 placed on the stabilizing rod placement frame 2 (in the V-shaped groove 210 of a pair of brackets 21). In this embodiment, the pressing rod mechanism comprises a pair of pressing rod cylinders 91, which are located between the pair of brackets 21, and the cylinder body 911 of each pressing rod cylinder 91 is vertically arranged on the workbench 1, and the push rod 912 of each pressing rod cylinder 91 extends upward from the cylinder body 911, and the top of each push rod 912 is provided with a pressing block 913 for pressing the stabilizing rod body.

[0027] In some specific implementations, the actions of the aforementioned tooling drive mechanism 5, stabilizer bar gripper 6, gripper rotation mechanism 7, push mechanism 8 and pressure rod mechanism are controlled by a PLC controller, and the working process is roughly as follows.

[0028] The manipulator slides the stabilizer bar 10 to be identified into the V-shaped groove 210 of the pair of brackets 21 through the slideway. The push rods 912 of the pair of pressure rod cylinders 91 retract downward, and the stabilizer bar 10 is pressed by the pressure block 913. The tool driving cylinder 5 pushes the identification tool 4 to move a predetermined distance in the direction close to the stabilizer bar placement rack 2, and moves from the initial position to the working position. At this time, since the end of the stabilizer bar has not yet completed the identification, the first end 101 of the stabilizer bar 10 and the identification groove 41 of the identification tool 4 are in a misaligned state, such as Figure 8 As shown. The push rod 81 of the push cylinder 8 extends, continuously pushing the mounting frame 3 to move toward the stabilizer bar placement frame 2, and the servo motor 7 and the stabilizer bar gripper 6 also move toward the stabilizer bar placement frame 2, until the first end 101 of the stabilizer bar 10 abuts against the orientation tooling 4. Two seconds after the push rod 81 of the push cylinder 8 begins to extend, the stabilizer bar gripper 6 moves, clamping the stabilizer bar 10 through a pair of clamping claws 61, as shown. Fig. 9 Then the servo motor 7 rotates, and since the push rod 81 of the push cylinder 8 continues to extend, when the first end 101 and the second end 102 of the stabilizing rod 10 rotate to align with the orientation recognition groove 41 of the orientation recognition tool 4, the first end 101 of the stabilizing rod 10 is pushed into the orientation recognition groove 41, and the orientation recognition is completed, as shown in FIG. Fig.10 and Fig.11 shown.

[0029] After the orientation is completed, the servo motor 7 stops, the pair of clamping claws 61 of the stabilizer bar gripper 6 is released, the push rod 81 of the push cylinder 8 and the push rod 51 of the tool driving cylinder 5 are retracted, driving the mounting frame 3 and the orientation tool 4 to move away from the stabilizer bar placement rack 2, and the push rods 912 of the two pressure rod cylinders 91 extend upward. Then, the stabilizer bar 10 that has completed the orientation is taken away from the stabilizer bar placement rack 2 by an external manipulator for subsequent molding work.

[0030] For different types of stabilizer bars, switching can be achieved by simply replacing the direction recognition tooling 4 and adjusting the torque setting value of the servo motor 7.

[0031] The stabilizer rod end orientation recognition device of the utility model embodiment has a high degree of automation. Compared with the manual operation method, the efficiency of the stabilizer rod end orientation recognition is greatly improved, thereby meeting the needs of large-scale automated production and reducing the labor intensity of the staff.

[0032] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
