[0022] The specific embodiment of the utility model is described in detail below in combination with the drawings and preferred embodiment.
[0023] As Figs. 1-3As shown, an automatic positioning mechanism for a fender support of an automobile includes a support base 1, a connecting plate 2, a guide rail 3, a telescopic cylinder 4, a double guide rod cylinder 5, and a fender support support block 6. The piston of the telescopic cylinder is hinged to the connecting plate, the bottom of the connecting plate is slidingly connected to the guide rail, the guide rail is fixed on the support base, a cylinder support plate 7 is fixed on the connecting plate, the double guide rod cylinder is fixed on one side of the cylinder support plate, an L-shaped connecting plate 8 is fixed on the piston rod of the double guide rod cylinder, a fender support pressing block 9 is fixed on the upper part of the L-shaped connecting plate, the fender support support block is located on one side of the fender support pressing block, and the fender support support block is fixed on the other side of the cylinder support plate through a connecting block. The fender support pressing block can press the fender support on the fender support support block under the driving of the double guide rod cylinder. Further, a buffer block connecting plate 10 is fixed on the side of the cylinder support plate, a buffer block 11 is arranged on the buffer block connecting plate, a limiting block 12 is fixed on the lower part of the double guide rod cylinder, and the limiting block cooperates with the buffer block. A sensor support 13 is fixed on the connecting plate, and a sensor 14 is fixed on the sensor support. Whether the fender support is pressed tightly by the double guide rod cylinder can be sensed by the sensor.
[0024] Further, in order to determine whether the connecting plate is in place, positioning blocks 15 are arranged on both sides of the support base, and stop irons 16 cooperating with the positioning blocks are arranged on both sides of the connecting plate. Positioning sensors 17 are arranged on both sides of the support base, and are used to monitor the positions of the stop irons.
[0025] Further, in order to determine whether the fender support is in place, a fender sensor 18 is arranged on one side of the fender support support block, and is used to sense whether the fender support exists.
[0026] Working principle:
[0027] In the first step, whether all sensor signals are turned on is checked, whether the sliding table gas circuit and the clamping unit gas circuit are unobstructed, and whether the magnetic attraction is sufficient to attract the support.
[0028] In the specific implementation, first, relevant parameters of the to-be-installed fender support are input to the control system. The system locks the moving route of the sliding platform and the final position of the clamping system according to the positioning device and the sensor switch detection.
[0029] In the second step, the operator places the fender support in the clamping unit area. Because of the fender support support block and the embedded magnet, the support can be better fixed. After the device is started, the fender sensor 18 senses that the fender support is in place, and the double guide rod cylinder retreats. The limiting block reaches the sensor 14 sensing position, the clamping state is realized, the workpiece is completed, the limiting block is in place, and the sensor sends an electric signal, so that the sliding table can be started.
[0030] In the third step, the program identifies that the manual loading and clamping are completed, the slide table starts to slide into the lower part of the outer panel of the fender from the loading station until the stopper reaches the limiting position, the in-position sensor senses that the stopper is in position, it is determined that the support has reached the fixed position, the program confirms, and the welding is started.
[0031] In the fourth step, the program determines that the welding is completed, and the slide table retreats to the loading position.
[0032] It should be noted that, for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should also be considered within the scope of protection of the present application.
