[0014] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.
[0015] like Figure 1-3 As shown, a repeatability detection device for a trolley fixture of an automobile welding conveyor line includes a cylinder 1, a first support 2, a first slide rail 3, a frame 4, a first limiting mechanism 5, a base plate 6, a detection device 7, a second support 8, a second limiting mechanism 9 and a second slide rail 10; the cylinder is mounted on the base plate through the first support, the first slide rail and the second slide rail are respectively fixed on both sides of the base plate, the bottom of the frame is slidably connected with the first slide rail and the second slide rail through a slider, the first limiting mechanism and the second limiting mechanism are respectively mounted on both sides of the base plate for limiting the frame, and the detection device is mounted on the front end of the frame through the second support. A sensor 12 is provided on the base plate, and the sensor is mounted on the base plate through a bracket 11.
[0016] The first limiting mechanism includes a first support seat 51, a buffer 52, a second support seat 53, a first gasket 54, a first stopper 55, a second stopper 56 and a second gasket 57. The first support seat is fixed to the side of the frame, the second stopper is installed on the first support seat through the second gasket, the second support seat is installed on the substrate, the first stopper is installed on the second support seat through the first gasket, and the buffer installation sub is between the first support seat and the second support seat. The second limiting mechanism is the same as the first limiting mechanism, and a position sensor is installed on the second limiting mechanism. It mainly plays a limiting role and can make the detection part stop accurately at the detection position.
[0017] The detection device includes a detection cylinder 71, a detection sleeve 72, a mounting block 73, a connecting block 74, a first sensor 75, and a second sensor 76. The detection cylinder is mounted on the frame, a connecting block is mounted on the piston rod of the detection cylinder, and the detection sleeve is mounted on the bottom of the connecting block through the mounting block. Through the above connection, the detection device can be extended to the detection position, and can also be retracted to the safe original position to avoid interference and collision with the trolley.
[0018] The cylinder can be freely controlled to extend and retract by an external air source; the bottom of the frame is installed on the slide rail, and the side is connected to the cylinder through the cylinder head, so the frame can be controlled to extend and retract by the cylinder, and the detection device and the second support are installed on the frame and are also controlled to extend and retract by the cylinder; the first limit mechanism and the second limit mechanism can accurately control the frame, the second support, and the detection device to stop at the position to be detected; the detection cylinder can also be freely controlled to extend and retract by an external air source.
[0019] When there is no trolley to be inspected, the cylinder drives the frame, substrate, and detection device to be retracted, and the sensor has a signal and transmits it to the PLC; when the trolley is in place, the PLC sends a trolley in place instruction, and the cylinder drives the frame, substrate, and detection device to extend, and the buffer quickly decelerates them before they are in place, and the first limit mechanism and the second limit mechanism accurately control their stop position, and the sensor in the second limit mechanism has a signal and transmits it to the PLC; after receiving the signal that cylinder 1 is extended into place, the PLC immediately ventilates the detection cylinder and drives the first detection sleeve and the second detection sleeve to extend. If the accuracy of the trolley locating pin is within 0.1mm, the first detection sleeve and the second detection sleeve can be smoothly inserted into the trolley locating pin, and the cylinder connected to it is extended into place. At this time, the second sensor can sense the side of the connecting block and directly transmit the sensing signal to the PLC, and the PLC determines that the detection is qualified. On the contrary, if the accuracy of the trolley positioning pin is greater than 0.1mm, the first detection sleeve and the second detection sleeve cannot be inserted into the trolley positioning pin, and the cylinder connected thereto cannot be extended into place. At this time, the second sensor cannot sense the side of the connecting block, and the second sensor has no signal. The PLC determines that the accuracy is unqualified and displays the information in the form of an indicator light. Regardless of whether the detection accuracy is qualified or not, after the detection is completed, the detection cylinder is ventilated and drives the first detection sleeve and the second detection sleeve to retract into place. At this time, the first sensor has a signal and transmits the sensing signal to the PLC. The PLC issues the next instruction to make the cylinder drive the frame, substrate, and detection device to retract into place. Sensor 12 has a signal again and transmits it to the PLC. The PLC learns from the sensor's detection signal that the detection device has retracted to the safe position, and issues the next instruction to make the trolley re-enter the line body (if the detection is qualified) or out of the line body (if the detection is unqualified) for manual maintenance.
[0020] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
