[0021] Example 1
[0022] like Figure 1-2 As shown, this utility model provides a reciprocating gantry fixture, including a workpiece running guide rail 1, a chain tensioning screw 2, a water pipe and air pipe crawler-type mounting plate 3, a reciprocating machine drive motor 4, a gantry column 5, a reciprocating machine 6, a water nozzle 7, an air nozzle 8, a workpiece to be inspected 9, a reciprocating machine traveling trolley 10, a reciprocating machine guide rail 11, a chain 12, and a chain drive rod 13, wherein:
[0023] The gantry columns 5 consist of four sets of square steel structures of the same height, used to support the reciprocating machine guide rails 11. One reciprocating machine guide rail 11 is installed on every two sets of gantry columns 5, vertically mounted on the ground on both sides of the workpiece running guide rail 1. The installation direction of the gantry columns 5 is parallel to the workpiece running guide rail 1. The reciprocating machine guide rails 11 are channel steel structures, laid flat on the gantry columns 5.
[0024] A reciprocating machine trolley 10 is installed on each reciprocating machine guide rail 11. The reciprocating machine trolley 10 has small wheels underneath, with the wheel width matching the width of the reciprocating machine guide rail 11, allowing it to move along the guide rail 11. A reciprocating machine 6 is fixedly installed on each reciprocating machine trolley 10, and the reciprocating machine 6 operates together with the reciprocating machine trolley 10.
[0025] A reciprocating machine drive motor 4 is fixedly installed at one end of the reciprocating machine guide rail 11, and a chain tensioning screw 2 is fixedly installed at the other end. The reciprocating machine drive motor 4 uses the chain 12 to drive the reciprocating machine 6 to move. The reciprocating machines 6 on both sides are connected by the chain drive rod 13 so that they can run synchronously.
[0026] The reciprocating machine 6 is a square steel structure, designed to be the same height as the workpiece 9 to be inspected, and perpendicular to the reciprocating machine guide rail 11. A rigid water pipe and an air pipe for cleaning are installed on the reciprocating machine 6. Several small holes are arrayed on the water pipe and air pipe, and water nozzles 7 and air nozzles 8 are installed on them respectively. The rigid water pipe and air pipe are connected to the water and air sources using flexible hoses. A water pipe and air pipe tracked mounting plate 3 is installed above the reciprocating machine guide rail 11. One end of the water pipe and air pipe tracked mounting plate 3 is connected to the reciprocating machine traveling trolley 10. The flexible hose is placed in the water pipe and air pipe tracked mounting plate 3, and the flexible hose moves in a serpentine motion with the track.
[0027] The workpiece 9 to be inspected is suspended on the workpiece running guide rail 1. After the workpiece 9 is cleaned, it runs along the workpiece running guide rail to enter the next process.
[0028] Furthermore, the reciprocating machine guide rail on the gantry is parallel to the workpiece running guide rail, the width of the reciprocating machine trolley is the same as the width of the reciprocating machine guide rail, the guide rail adopts a grooved track, and wheels are installed on the reciprocating machine trolley. The wheels are locked in the grooves, which can ensure that the reciprocating machine trolley can move easily on the reciprocating machine guide rail without derailing.
[0029] Furthermore, the track mounting plate is the same length as the reciprocating machine.
[0030] It should be noted that, since the water pipes on the reciprocating machine move left and right with the machine, flexible hoses are used to connect the water and air sources to the reciprocating machine's pipelines and are installed in the track mounting plate. Therefore, the track mounting plate is the same length as the reciprocating machine.
[0031] Furthermore, the servo motor is controlled by a PLC programmable controller, and the number of cleaning cycles can be set through program settings or touch screen settings.
[0032] Furthermore, the nozzles installed on the reciprocating machine are controlled in segments, with each segment connected to a water pipe and an air pipe, and a solenoid valve or switch installed on each pipe.
[0033] Furthermore, the reciprocating machine is installed on both sides of the workpiece running guide rail, which can simultaneously clean and blow air onto the workpiece to be inspected.
[0034] Furthermore, the reciprocating machines are connected by a chain drive rod, enabling one reciprocating machine drive motor to simultaneously drive two reciprocating machines to move synchronously.
[0035] Furthermore, an independent control unit is installed near the reciprocating gantry, which controls the opening and closing of the water and air sources, as well as the movement of the reciprocating machine drive motor, via buttons, thus achieving manual control.
[0036] Furthermore, installing a servo motor and commutator on the reciprocating machine guide rail ensures that the servo motor drives the reciprocating machine to move left and right through the commutator.
[0037] It should be noted that the temperature range of the water used for penetrant testing and cleaning is 10℃~38℃, and the pressure is less than 270kpa. Generally, the water used for cleaning needs to be heated by a water tank and supplied by a water pump. The temperature and pressure indicators are installed in a position that is easy for the operator to observe.
[0038] It should be noted that the present invention provides a reciprocating gantry fixture including a gantry column for mounting the reciprocating machine and a reciprocating machine guide rail. The reciprocating machine drive motor is mounted on the reciprocating machine guide rail and drives the reciprocating machine to move back and forth using a chain. Guide rods for cleaning water nozzles and compressed air nozzles are installed parallel to each other on both sides of the reciprocating machine. The cleaning water pipe and the air pipe use tracked guide rails.
[0039] It should be noted that the length of the reciprocating machine guide rail can be designed according to the workpiece length and site conditions. The height of the gantry column can be designed according to the workpiece height and site conditions.
[0040] It should be noted that, depending on the roughness of the workpiece being inspected, one or more sets of nozzles can be designed.
[0041] It should be noted that during automatic operation, the number of automatic travels of the reciprocating machine can be set via the touch screen.
[0042] It should be noted that a manual spray gun is installed at this cleaning station so that manual cleaning can be performed when the automatic cleaning is insufficient.
[0043] Example 2
[0044] This utility model provides a method for using a reciprocating gantry fixture, including:
[0045] In automatic mode: Before cleaning, adjust the cleaning water pressure and compressed air pressure, and set the cleaning and blowing frequency. After the workpiece being inspected has moved and stopped at the cleaning station, press the start button to operate according to the set program.
[0046] In manual mode: Before cleaning, adjust the cleaning water pressure and compressed air pressure. After the workpiece being inspected has stopped running at the cleaning station, turn on the water pump and press the left and right buttons of the reciprocating machine to operate.
[0047] The above implementation examples are merely examples of novel applications and should not be used to limit the scope of patent protection by describing exemplary embodiments in the specification and drawings.
[0048] In summary, this application provides a reciprocating gantry fixture that integrates cleaning and air blowing, and can be used as an automatic or manual fixture for cleaning excess penetrant from surfaces in penetrant testing processes. Through programmable control, the number of reciprocating cleaning and air blowing cycles can be set according to the standard penetrant testing process requirements to achieve automatic cleaning and air blowing operations. An independent control button can be installed at the cleaning station to achieve manual control of cleaning and air blowing. The cleaning distance can be adjusted according to the size of the part, based on the cleaning distance requirements in the penetrant testing process. The nozzles on the gantry are segmented for control, allowing adjustment of the cleaning height according to the height of the part, achieving water conservation. Single or multiple sets of nozzles can be designed according to the actual surface roughness of the workpiece.
[0049] This application provides a reciprocating gantry fixture, comprising an automatic water washing system for removing excess penetrant from the workpiece surface and a compressed air system for blowing away excess moisture from the workpiece surface during the penetrant testing process. A U-shaped gantry is used, mounted on the running guide rail of the testing line, and can reciprocate along the guide rail. Cleaning water nozzles and compressed air nozzles are installed on both sides of the gantry, and the distance between the nozzles and the workpiece surface can be adjusted according to process requirements. PLC electrical control is used, and the automatic cleaning and air blowing operation is achieved by setting the number of cleaning cycles according to process requirements. The gantry reciprocating movement can also be manually controlled via buttons. This can replace the manual operation of cleaning parts with handheld water guns and air guns by operators, reducing cleaning time, lowering labor intensity, improving testing efficiency, and saving testing water.

However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge in the art, various changes can be made without departing from the concept of the present invention.
