It is formed on the basis of the further development of the continuous assembly line. Existing automatic production lines are equipped with corresponding robots to operate.

[0003] Existing automatic production line robots may cause deviation and crooked clamping during the process of clamping and placing the blanks. Since the existing robots only have simple functions of placement and clamping, they are unable to perform corresponding processing in the case of deviation and crooked clamping, making it very easy for the blanks to be deviated or clamped during the processing, resulting in machine tool runaway and collision accidents. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that the blank may be misaligned or distorted during machining, which may lead to machine tool runaway and collision accidents, and proposes an automatic line robot anti-misalignment and anti-collision system.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The automatic line robot anti-deflection and anti-collision system comprises a mounting bracket mounted on the robot, and the mounting bracket is provided with:

[0013] Preferably, a guide long slot is provided on the eight-shaped mounting rod, a guide slider is slidably sleeved in the guide long slot, and a traction rod is pin-connected between the guide slider and the mounting bracket.

[0014] Preferably, the driving mechanism comprises:

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Reference Figure 1-Figure 3 The automatic line robot anti-deflection and anti-collision system includes a mounting bracket 1 installed on the robot, and the mounting bracket 1 is provided with a placement frame 2, a clamping member 3, a through-beam photoelectric switch 4 and a driving mechanism. The components are arranged as follows:

[0028] The placement frame 2 is fixedly connected to the mounting bracket 1;

[0029] The clamping member 3 is rotatably mounted on the mounting frame 2. The mounting frame 2 is provided with an active long hole for the movable set clamping member 3. The active long hole can provide a movable space for the deflection movement of the clamping member 3. The through-beam photoelectric switch 4 is installed at the clamping end of the clamping member 3, so that after the discharge is completed, the horizontal surface of the wheel hub can be detected by the through-beam photoelectric switch 4. By monitoring the photoelectric signal, it is determined whether the discharge is deviated, which helps to avoid the wheel hub from running away or crashing due to the deviated discharge during the processing. The through-beam photoelectric switch 4 is electrically connected to the alarm light provided in conjunction with the automatic production line. It should be noted that the alarm light is a necessary supporting facility for the automatic production line, so the alarm light will not be described in detail;

[0030] A further implementation method is that the clamping member 3 includes an eight-shaped mounting rod 301 and a clamping roller 302, and each component is arranged as follows:

[0031] The pin of the eight-shaped mounting rod 301 is installed in the movable long hole, and the through-beam photoelectric switch 4 is installed on the eight-shaped mounting rod 301, and the clamping roller 302 is set at the bottom end of the eight-shaped mounting rod 301;

[0032] A guide slot 5 is provided on the eight-shaped mounting rod 301, and a guide slider 6 is slidably mounted in the guide slot 5. When the guide slider 6 is guided and limited by the guide slot 5, it helps to ensure the stability of the guide slider 6 in the guide slot 5. A traction rod 7 is connected to the guide slider 6 and the mounting bracket 1 by a pin shaft.

[0033] The driving mechanism is installed on the mounting bracket 1, and the driving mechanism is used to drive the clamping members 3 to move toward each other;

[0034] A further implementation method is that the driving mechanism includes a motor 8, a ball screw 9, a nut 10 and a driving rod 11, and each component is arranged as follows:

[0035] The motor 8 is fixedly connected to the mounting bracket 1;

[0036] One end of the ball screw 9 is fixedly connected to the output end of the motor 8, and the other end of the ball screw 9 is rotatably mounted on the mounting bracket 2. The nut 10 is matched with the ball screw 9. A dust cover is matched between the nut 10 and the mounting bracket 1 or between the nut 10 and the mounting bracket 2, and the dust cover is sleeved on the ball screw 9. The setting of the dust cover helps to ensure that the ball screw 9 will not be contaminated by dust during operation, which helps to extend the service life of the ball screw 9.

[0037] The two ends of the driving rod 11 are pin-connected to the nut 10 and the eight-shaped mounting rod 301 respectively;

[0038] It should be noted that the specific models and specifications of the through-beam photoelectric switch 4 and the motor 8 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0039] The functional principle of the utility model can be explained through the following operation modes:

[0040] The detection function of the through-beam photoelectric switch 4 is turned on, and the motor 8 is started. The motor 8 drives the ball screw 9 to rotate, so that the nut 10 moves horizontally on the ball screw 9, and the nut 10 drives one end of the driving rod 11 to move linearly. The other end of the driving rod 11 drives the eight-shaped mounting rod 301 to close, so that the guide slider 6 moves in the guide long groove 5, and the guide slider 6 drives the traction rod 7 to deflect. The eight-shaped mounting rod 301 drives the clamping roller 302 to clamp the wheel hub to be processed. After the material is discharged, the through-beam photoelectric switch 4 is driven by the robot to move to the monitoring point, scan the wheel hub plane, and determine whether the discharge is deviated by monitoring the photoelectric signal;

[0041] When the horizontal surface of the wheel hub is detected to have bulges and unevenness, the photoelectric signal is triggered, the robot stops immediately, and the external alarm light is triggered to prompt the operator to check whether the wheel hub is level and clamped in place. After processing and confirmation, the machine tool cycle processing is started again.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
