Nissan 600 sets of 117/118 bearing seat production line plan

1. Production guidelines:

600 sets/day (117/118 bearing seat)

2. Requirements of the processing line:

1) CNC machining center suitable for automatic production line;

2) Hydraulic tooling fixture;

3) Automatic loading and unloading device and conveying device;

4) The overall processing technology and processing rhythm.

The automatic production line storage equipment of this scheme is stacked trays (the quantity of each tray needs to be negotiated with the customer), and the workpiece in the tray is fixed

It will be determined after providing 3D drawings or real objects of the workpiece blanks.

1. The worker puts the rough-machined parts into the material tray (as shown in the figure), and forks to the designated position by the forklift;

2. After the forklift replaces the material tray, manually press the button to confirm;

3. The robot grabs the workpiece for loading work.

This structure adopts joint robot, servo motor drive, rack, and pinion transmission, etc., which makes the robot perform linear motion back and forth; realizes the function of one robot serving multiple machine tools and multi-station grabbing workpieces, which can increase the working coverage of the joint robot;

The walking track adopts a steel pipe welded base, a servo motor, and a rack and pinion drive mode to increase the working coverage of the joint robot and effectively improve the utilization rate of the robot;

The walking track is installed on the ground.

It has a wide range of motion including the back and bottom of the robot and can be mounted on a ceiling-mounted model. Because the lateral width of the robot is reduced to the limit, it can be installed close to adjacent robots, fixtures, or workpieces. High-speed movement from the standby position to the working position, as well as rapid positioning during short-distance movement.

1. According to the characteristics of the part, we adopt the three-jaw external support method for loading and unloading, which can quickly realize the U-turn of the part in the machine tool;

2. The mechanism is equipped with a position detection sensor and a pressure sensor to detect the clamping status of the parts and whether the pressure is normal;

3. The mechanism is equipped with a pressure maintaining device, and the workpiece will not fall off in a short time when the power is cut off and the main gas circuit is cut off;

4. Using a hand-changing device, by replacing the gripping mechanism, the gripping of different materials can be completed quickly.

The precise hand changing device is used to quickly change the gripper, tool end, and other actuators of the manipulator. Reduce production idle time and improve the flexibility of the robot. Its characteristics:

1. Unlock and tighten by air pressure;

2. Various power, liquid, and gas modules can be used;

3. The standard configuration can be quickly connected to the gas source;

4. Special insurance agencies prevent the risk of accidental air loss;

5. There is no spring reaction force;

6. Applicable to the field of automation.
