[0007] As a further improvement of the present invention, the clamp comprises a lower seat and an upper seat which can rotate around the lower seat. The lower pressing block presses the right end of the upper seat downward, and the upper seat tilts to the right side.

[0008] As a further improvement of the present invention, the lower seat is provided with a main beam and a first elastic member that fits with the bottom surface of the upper seat, the main beam is provided with a rotatable first pin, the upper seat is provided with a sub-beam, a vertical block, two supports symmetrically arranged front and rear, and two side pressure plates that can press the workpiece, the sub-beam is socketed with the first pin, a rotatable bearing is provided at the upper end of the vertical block, the middle part of the side pressure plate is rotatably connected to the support through a second pin, and the upper seat is also provided with a second elastic member that fits with the bottom of the side pressure plate, and the second elastic member is located on the right side of the support. The worker presses the right end of the side pressure plate with his right hand, and the middle part of the side pressure plate rotates around the second pin, the left end of the side pressure plate rises, and the second elastic part is compressed. Then the left hand puts the workpiece on the upper seat, releases the right hand, and the side pressure plate can press the workpiece under the action of the second elastic part; the lower seat is fixed, and the first elastic part will push the upper seat upward; the plug is clamped by the robot, and when the lower pressure block of the pressing mechanism moves downward, the lower pressure block will press the bearing at the upper end of the vertical block. Because the secondary beam can rotate around the main beam, the upper seat is pressed by the lower pressure block to a predetermined inclination angle, and the threaded hole and the plug are kept coaxial. Finally, the robot starts to rotate and screws the plug into the threaded hole of the workpiece; during the pressing process, the bearing is in close contact with the lower pressure block to ensure that all components can move smoothly during the pressing process.

[0009] As a further improvement of the present invention, the transmission line passes through a limiting device, which includes a box body, a front limiting mechanism, and a rear limiting mechanism fixed to the box body; the front limiting mechanism includes a power part and a fixed plate fixed to the power part; the fixed plate is provided with a front limiting block which can be driven and rotated by the power part; the rear limiting mechanism includes a self-locking seat and a self-locking block which can rotate around the self-locking seat; an upper magnet is provided in the self-locking block; the self-locking seat is provided with a lower magnet; the magnetic poles on the upper end face of the lower magnet are opposite to the magnetic poles on the lower end face of the upper magnet so that the two can produce a repulsive force and separate from each other; a light emitter and a light receiver are installed on the upper end of the box body.

The power part of the front limit mechanism can lift the front limit block so that the front limit block blocks the left side of the fixture and prevents it from moving; when the entire fixture enters the frame, the upper end of the self-locking block has no contact with the fixture, and after the upper magnet is subjected to the magnetic force of the lower magnet, the left end of the self-locking block rises and then presses against the right side of the fixture, so both the left and right sides of the fixture are fixed.

The frame assembly is fixed to the connecting frame of the auxiliary device; when the push plate drives the movable seat assembly, the circular movable groove with an inclined angle will drive the second pin rod to tilt and move, so that the upper ends of the two clamping blocks are separated from each other, because the middle part of the clamping block can rotate around the first pin rod, so the lower ends of the two clamping blocks are just close to each other, so that the clamping block can clamp the plug, and when the driving assembly drives the rotating shaft to rotate, the connecting plate and the two clamping blocks rotate together to screw the plug into the threaded hole of the workpiece.

[0011] As a further improvement of the present invention, the frame assembly includes a connecting seat, a base fixedly connected to the connecting seat, the driving assembly is installed on the connecting seat, the driving assembly includes a motor, and a reducer fixedly connected to the rotating shaft, and the base is fixedly installed on the connecting frame.

[0012] As a further improvement of the present invention, the fuselage is provided with a second cylinder for driving the fixed seat to slide, the fixed seat is provided with an upper connecting block and a third cylinder, the rotating seat is provided with a fourth cylinder for driving the connecting frame to slide, a first lower connecting block connected to the third cylinder, and a second lower connecting block connected to the upper connecting block, and the connecting frame is provided with a fifth cylinder for driving the push plate to slide. The second cylinder drives the fixed seat to slide horizontally so that the manipulator moves to the top of the feeding line; the rotating seat can rotate around the upper connecting block, the third cylinder drives the first lower connecting block, so that the clamping mechanism and the plug of the feeding line are on the same axis; and the fourth cylinder drives the connecting frame to slide so that the manipulator is close to the feeding line; the frame assembly is fixedly installed at the connecting frame, and the push plate is fixedly connected to the clamping mechanism, so the fifth cylinder can drive the clamping mechanism to grab the plug.

The first guide rail slider assembly, the second guide rail slider assembly, and the third guide rail slider assembly are all designed to make the relative movement of two adjacent connecting parts smoother, more stable, more precise, less resistant, and less energy consuming.

[0014] As a further improvement of the present invention, the driving mechanism includes a driving seat, a longitudinal slide that can move up and down at the driving seat, a transverse slide that can move left and right at the longitudinal slide, and a drag plate that can move up and down at the transverse slide, the longitudinal slide is provided with a pressing plate that can press the workpiece, and the anti-breakage base block is installed at the drag plate. The driving seat can be fixed on the ground, wall and other places, and it is fixed; through the longitudinal slide, transverse slide, and drag plate, it moves in multiple directions, and finally the pressing plate will press the upper end of the workpiece to keep the workpiece fixed, and the insert of the anti-breakage base block will be stuck in the gap of the workpiece.

[0016] The advantages of the present invention are high automation and high production efficiency; specifically: the transmission line sends the clamp to the limit device, and the limit device can limit and fix the clamp; the vibration plate can transport the plug to the feeding line for the clamping mechanism to grab, and the manipulator can realize multi-directional movement under the control of the auxiliary device, and finally screw the plug into the threaded hole of the workpiece; in the process of screwing the plug in, the gear rib will hit the gear bar, and the gear rib is easy to break. In view of this situation, an anti-breakage mechanism is provided, which includes an arc-shaped insert, and the driving mechanism clamps the insert into the neutral position. Because the gear rib is in contact with the insert, the gear rib is bent and the jitter amplitude is small during the process of screwing the plug in, so the gear rib can be effectively prevented from breaking, and the blocking piece can block the screw-in end of the plug to prevent the plug from being screwed over; when the entire equipment has just been manufactured and the equipment has been used for a long time After a period of time, when the auxiliary device drives the manipulator to screw the plug into the threaded hole of the workpiece, the inclination angle of the clamping mechanism and the inclination angle of the threaded hole may deviate, that is, the coaxiality error, resulting in the plug being unable to align with the threaded hole. This requires adjustment of the dimensions of related mechanisms and parts to meet production requirements. If it is difficult to adjust the inclination angle of the auxiliary device, a pressing mechanism is set up. The lower end face of the pressing block is ground by a grinder or a new pressing block is replaced to control the inclination angle produced when the pressing block presses the fixture, so that the inclination angle of the clamping mechanism is consistent with the inclination angle of the threaded hole. The lower end face of the fixture is ground by a grinder or the bottom parts of the fixture are replaced with new ones. The clamping mechanism and the threaded hole can be made concentric. The cost of processing or replacing the pressing block and the bottom parts of the fixture is low, and debugging time can be saved. BRIEF DESCRIPTION OF THE DRAWINGS
