[0016] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by “up”, “down”, “left”, “right”, “inside”, “outside”, “top”, “bottom”, etc. are all based on the directions or positional relationships shown in the accompanying drawings. The purpose is only to facilitate the description of the present invention and simplify the description. It does not indicate or imply that the referred parts must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0018] Depend on Figures 1 to 3 As shown, an A-axis detection device of a large-scale ground rail gantry automatic tape laying machine includes an A-axis inspection fixture seat, which includes two connecting plates 3, two support frames 2 and a bottom plate 1. The bottom plate 1 is used to fix the rotary axis calibration device. A plurality of flange holes 10 evenly distributed in the circumferential direction are opened in the middle of the bottom plate 1. The flange holes 10 match the connecting holes on the flange 4 of the rotary axis calibration device.

[0019] The connecting plate 3 is parallel to the bottom plate 1, and the two connecting plates 3 are symmetrical. The end of the connecting plate 3 close to the center of the bottom plate 1 is arc-shaped, and a number of circular holes are opened on the arc-shaped plate. The tape laying head body is connected to the circular holes through screws B6, so that the tape laying head body is connected between the two connecting plates 3. The other end of the connecting plate 3 is connected to the support frame 2 through screws C9. The two support frames 2 are respectively located at the left and right ends of the bottom plate 1, and the support frames 2 are perpendicular to the connecting plate 3 and the bottom plate. The hole on the connecting plate 3 corresponding to the screw C9 is the connecting plate oblong hole 8, and the hole on the support frame 2 corresponding to the screw C9 is a normal circular hole, so that the support frame 2 and the connecting plate 3 can move relative to each other in the long axis direction of the connecting plate oblong hole 8.

[0020] A flat plate is fixed on the top of the support frame 2, and the flat plate is used to connect with the bottom plate 1. The top flat plate of the support frame 2 is connected to the bottom plate 1 by screws A5, and the hole on the bottom plate 1 corresponding to the screw A5 is the bottom plate oblong hole 7. A normal round hole is opened on the top flat plate of the support frame 2, so that the bottom plate 1 and the support frame 2 can move relative to each other in the long axis direction of the bottom plate oblong hole 7. The oblong hole 8 of the connecting plate is perpendicular to the length direction of the oblong hole 7 of the bottom plate, so that the tape laying head body connected by the connecting plate 3 can move in the up and down and left and right directions relative to the bottom plate 1, so as to calibrate the A-axis accuracy of the tape laying head body.

[0021] The detection device is also equipped with a rotary shaft calibration device during operation. The rotary shaft calibration device is fixed to the flange hole 10 of the base plate 1 via a rotary shaft calibration device flange 4 .

[0022] A method for detecting the A-axis of a large-scale gantry-type automatic tape laying machine for ground rails, using the above-mentioned detection device, Figures 4 to 6 The schematic diagram of the detection device connected to the tape laying head specifically includes the following steps: Step 1: Assemble the A-axis inspection fixture. At this time, all screws A5 and C9 can be preliminarily connected and not tightened temporarily to facilitate later adjustments.

[0023] Connect the tape laying head body between the two connecting plates 3, and connect the tape laying head body to the connecting plates 3 through screws D6, so as to connect the A-axis gauge seat to the tape laying head body. Since there is no need to adjust between the tape laying head body and the connecting plates 3, screws D6 can be tightened directly. Initially connect the rotary axis calibration device flange 4 to the flange hole 10 of the base plate 1. At this time, the screws D11 at the flange hole 10 are temporarily not tightened, so that the rotary axis calibration device can be slightly adjusted.

[0024] Step 2: Press the dial indicator contact onto the outer circle of the rotary axis calibration device and use the dial indicator to detect the position accuracy of the A axis of the tape laying machine.

[0025] Step 3, adjust the up and down position of the A-axis gauge according to the value of the dial indicator. At this time, observe the dial indicator reading, and determine whether the up and down position of the A-axis is offset according to the reading. Since the connection between the connecting plate 3 and the support frame 2 is the connecting plate oblong hole 8, move the support frame 2 in the connecting plate oblong hole 8 of the connecting plate 3, so as to preliminarily adjust the up and down position of the A-axis gauge relative to the tape laying head.

[0026] Step 4: Adjust the left and right position of the A-axis gauge according to the value of the dial indicator. Similarly, observe the dial indicator reading and determine whether the left and right position of the A-axis is offset according to the reading. Since the connection between the bottom plate 1 and the support frame 2 is the bottom plate oblong hole 7, move the bottom plate 1 and change the position of the support frame 2 in the bottom plate oblong hole 7 on the bottom plate 1, thereby preliminarily adjusting the left and right position of the A-axis gauge relative to the tape laying head.

[0027] Step 5. After the preliminary adjustment in steps 3 and 4, the precision error of the A axis of the tape laying machine is very small. Usually, this error can be compensated by moving the rotary axis calibration device. At this time, the position of the rotary axis calibration device flange 4 on the flange hole 10 is adjusted according to the indication of the dial indicator, and the precision of the A axis of the tape laying machine can be accurately adjusted.

[0028] When the dial indicator shows that the upper and lower positions and the left and right positions of the tape laying head meet the requirements, tighten the screws at each connection in turn to fix the relative position of the rotary axis calibration device and the tape laying head. The screws that need to be tightened include screw A5, screw C9, and screw D11, and during the tightening process, care should be taken not to change the dial indicator reading.

[0029] Step 6: Use the rotary axis calibration device to test the positioning accuracy of the A axis of the tape laying machine.

[0030] The present invention designs an A-axis gauge seat, and connects the A-axis gauge seat to the tape laying head body. The A-axis gauge seat can be used to perform preliminary up, down, left, and right position adjustments on the tape laying machine. After the preliminary adjustment, the position error is already very small, and then the flange of the rotary axis calibration device is slightly moved to perform fine adjustment, so that the error between the flange center of the rotary axis calibration device and the center of the A-axis swing angle is within the allowable range, thereby fixing the relative position of the rotary axis calibration device and the tape laying head body. After the positions of the two are fixed, the A-axis positioning accuracy and repeated positioning are detected and compensated by the rotary axis calibration device, thereby ensuring the measurement accuracy. The present invention is suitable for the detection and compensation of the A-axis swing angle accuracy of the tape laying machine, and the operation is safe and labor-saving, and the A-axis swing angle accuracy of the tape laying machine is improved, thereby improving the work efficiency.

Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
