DETAILED DESCRIPTION

[0019] like Figures 1 to 5 As shown, the lateral surface grinding device of the automobile bridge shell plate of the present invention comprises a conveyor line, a lateral grinding device, and a mounting support frame. The conveyor line comprises a bracket and a conveying roller, and guide plates for guiding the automobile bridge shell plate are respectively arranged on both sides of the front end of the conveyor line. The conveyor line is an existing design and is not described in detail here. The mounting support frame is connected to the edges of both sides of the conveyor line, and the lateral grinding device is arranged in the conveyor line and supported by the mounting support frame at both ends. The lateral grinding device comprises a mounting connecting plate I, a mounting connecting plate II, a middle cylinder push-pull mechanism, and a lateral grinding assembly. Bolt holes are arranged at both ends of the mounting connecting plate I for fixed connection with the mounting support frame. The mounting connecting plate II is vertically connected to the upper surface of the mounting connecting plate I, and the two ends of the mounting connecting plate I are longer than the mounting connecting plate II and protrude at both ends to connect with the mounting support frame. A slide rail is connected to one side surface of the mounting connecting plate II. The mounting connecting plate II is connected to a plurality of L-shaped support blocks on the back of the surface connected to the slide rail, and the bottom end of the L-shaped support block is fixedly connected to the upper surface of the mounting connecting plate I. The top of the mounting connecting plate II is also connected to a baffle covering the upper side of the slide rail, and the baffle can prevent dust and flying burrs from falling onto the slide rail during the grinding process.

[0020] The central cylinder push-pull mechanism includes a cylinder mounting bracket, a cylinder, and a connecting rod. A cylinder positioning hole for the cylinder to pass through is also provided in the middle of the mounting connecting plate II. The cylinder mounting bracket is connected to the outer edge of the cylinder positioning hole on the surface of one side of the slide rail of the mounting connecting plate II. The cylinder is mounted on the cylinder mounting bracket and positioned in the cylinder positioning hole in the middle of the mounting connecting plate II. The outer end of the piston rod of the cylinder is hinged to one end of two symmetrically arranged connecting rods on both sides of the cylinder through the connecting piece I, and the other ends of the two connecting rods are respectively hinged to the lateral grinding assembly. The lateral grinding assembly includes a motor mounting frame, a servo motor, an oblique connecting block, a slider, and a grinding disc. The servo motor is connected to the bottom end of the motor mounting frame, the grinding disc is arranged at the upper end of the motor mounting frame and connected to the output shaft of the servo motor, the slider is connected to one side surface of the oblique connecting block, and the other side surface of the oblique connecting block is connected to the motor mounting frame. The slider cooperates with the slide rail on the surface of the mounting connecting plate II and can slide relatively.

[0021] In this embodiment, the oblique connection block is a steel plate with a right-angled trapezoidal cross section. The plane where the right-angled trapezoidal hypotenuse is located is connected to the motor mounting frame, so that the motor mounting frame is tilted in the vertical direction, and the grinding disc installed on the motor mounting frame is also tilted in the vertical direction. The tilting of the grinding disc can increase the contact area between the grinding disc and the lateral surface of the automobile bridge shell plate, thereby improving the grinding efficiency. The right-angled surface opposite to the surface where the hypotenuse of the oblique connection block is located is connected to the slider. One side surface of the installation connection plate II is connected to two parallel slide rails, and each oblique connection block is connected to two slide rails corresponding to the positions of the two slide rails, and the cylinder positioning hole is set in the middle between the two slide rails. The inner side wall of the oblique connection block is connected to a connecting piece II, and the connecting rod is hinged to the connecting piece II at one end away from the cylinder. A travel switch is connected to the cylinder mounting bracket, and the travel switch is used to detect the position of the automobile bridge shell plate on the conveyor line. When the automobile bridge shell plate is detected, a signal is sent to the control system, and the control system controls the servo motor to start working, and the servo motor drives the grinding disc to rotate to grind the surfaces on both sides of the automobile bridge shell plate.

[0022] During operation, the robot puts the cut automobile axle shell plate on the roller of the conveyor line, and the conveyor line conveys the automobile axle shell plate backwards. When the travel switch detects the automobile axle shell plate, it sends a signal to the control system. The control system controls the cylinder to work. According to the side position of the automobile axle shell plate, the cylinder pushes the connecting rod so that the grinding disc is just located at the side edge of the automobile axle shell plate, and controls the servo motor to start working. The servo motors on both sides of the cylinder turn in opposite directions to grind the surfaces of both sides of the automobile axle shell plate respectively. The conveyor line continuously pushes the automobile axle shell plate backwards. The cylinder can adjust the position of the grinding disc by pushing the connecting rod according to the side contour of the automobile axle shell plate, so that the surface of the grinding disc is always close to the side of the automobile axle shell plate, thereby realizing fully automatic grinding of rust and burrs on the side of the steel plate.

[0023] The above embodiments are only preferred embodiments of the present invention. The structure of the present invention is not limited to the forms listed in the above embodiments. Any modifications, equivalent substitutions, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
