[0026] Ginseng Figures 1 to 6 As shown, a welding fixture for a ship-shaped metal part comprises a horizontally arranged workbench 1 and a first fixture and a second fixture respectively arranged on the top of the workbench 1. The first fixture and the second fixture are used to detect the welded ship-shaped metal part in steps. The ship-shaped metal part comprises two oppositely arranged ship-shaped plates, a bottom plate arranged between the two ship-shaped plates, a reinforcement plate and two connecting plates, wherein the two sides of the bottom plate and the two connecting plates are respectively plugged and welded to the corresponding ship-shaped plates, and the two ends of the top surface of the reinforcement plate are respectively welded to the bottom surface of the corresponding ship-shaped plates. The first fixture comprises a A holder 2 is placed on the top surface of the workbench 1 and a first through-gauge 3 is clamped to the holder 2. The second inspection fixture includes two groups of support frames 4 relatively arranged on the top surface of the workbench 1, a support seat 5 arranged between the two groups of support frames 4, and a clamping device 6 rotatably arranged on the top surface of the workbench 1. The clamping device 6 includes a quick clamp 62 arranged on the workbench 1 through a mounting block 61 and a clamping block 63 connected to the quick clamp 62. The clamping block 63 includes a connecting arm connected to the quick clamp 62, a mounting arm connected to the connecting arm, and two pressure rods 64 arranged on the mounting arm.

[0027] In this technical solution, the workbench is a conventional plate-like structure, which is disassembled and assembled on the line body assembled by profiles, etc. The specific structure is the existing technology and will not be described here one by one. Handles are installed at both ends of the workbench for easy transportation. The conventional bolts of the clamping block gauge are installed on the top surface of the workbench, and an opening for clamping the first gauge is provided on the top. When the first gauge is not in use, it is clamped in the clamping block to avoid loss or confusion with other types of gauges. The conventional bolts and cylindrical pins of the mounting block gauge are fixed to the top surface of the workbench, and the base of the quick clamp is fixed to the top surface of the workbench. Gauge bolts and the like are fixed to the top of the mounting block, and the push handle and clamp of the quick clamp are hinged to the base, thereby driving the pressing block to rotate through the quick clamp. The ship-shaped metal part is fixed by clamping the bottom plate between the support seat and the pressure rod, and the ship-shaped plate is placed between the two support frames. At the same time, the hole positions in the two ship-shaped plates are detected to improve the detection efficiency and accuracy. The welding inspection fixture of the ship-shaped metal part has a simple structure and is used for the inspection of the ship-shaped metal part after welding. It can be clamped once and is easy to operate. It can also detect the relative position accuracy between multiple holes at the same time.

[0028] For example, see Figure 1 and Figure 2As shown, one end of the first through gauge 3 is provided with a guide portion for easy operation, and the other end is connected to a first handle 31 , which is clamped to the clamping base 2 .

[0029] In this technical solution, the first handle is a hexagonal rod or other structure, and a stud is processed at one end close to the first through gauge, and a threaded hole corresponding to the stud is processed at the corresponding end of the first through gauge, which is convenient for disassembly and assembly. At the same time, the first through gauge is operated by holding the first handle without contacting the first through gauge, thereby avoiding contamination of the surface of the first through gauge by sweat on the hands and extending the service life of the first through gauge. In addition, the first handle is clamped on the clamping base to avoid scratches caused by contact between the clamping base and the first through gauge.

[0030] For example, see Figure 2 As shown, the length of the first through gauge 3 is greater than the distance between the two ship-shaped plates.

[0031] In this technical solution, the first through gauge is used to detect the coaxiality of some corresponding holes between the two ship-shaped plates, that is, the first through gauge needs to pass through the two ship-shaped plates at the same time, and the detection must be completed before clamping. The support platform and the support frame do not need to avoid the detection position of the first through gauge, thereby simplifying the structure.

[0032] For example, see Figure 1 As shown, the support frame 4 includes two symmetrically arranged first mounting seats 41 and two symmetrically arranged second mounting seats 42. The first mounting seat 41 is provided with a second through gauge 43 corresponding to the ship-shaped plate, and the second mounting seat 42 is provided with a third through gauge 44 and a fourth through gauge 45 corresponding to the ship-shaped plate respectively.

[0033] In this technical solution, a space for accommodating the ship-shaped metal parts is formed between the two groups of support frames, and the outer walls of the ship-shaped plate slide and fit onto the inner walls of the corresponding first mounting seat and the second mounting seat respectively. The first mounting seat and the second mounting seat are respectively set on the top surface of the workbench by bolts and cylindrical pins, and the top surfaces of the first mounting seat and the second mounting seat are set according to the contour of the ship-shaped plate, which is convenient for observing whether the ship-shaped metal parts are fixed in place. The second through gauge, the third through gauge and the fourth through gauge correspond to the hole positions in the ship-shaped plate respectively, and the relative positions of the twelve hole positions are detected on both sides at the same time to improve efficiency.

[0034] For example, see Figures 3 to 5 As shown, a support block 46 is provided on the inner wall of the first mounting seat 41 , and a support groove corresponding to the ship-shaped plate is formed between the support block 46 and the corresponding first mounting seat 41 .

[0035] In this technical solution, the support block is installed on the inner wall of the corresponding first mounting seat by bolts, and a step groove is processed in the side wall close to the first mounting seat, and a support groove is formed with the inner wall of the first mounting seat, and the two ship-shaped plates are respectively inserted into the support grooves.

[0036] For example, see Figures 3 to 5As shown, a first through hole perpendicular to the corresponding ship-shaped plate is provided in the first mounting seat 41, a first bushing 47 for accommodating the passage of the second through gauge 43 is provided in the first through hole, and the first through hole is staggered with the support block.

[0037] In this technical solution, the first bushing is made of Teflon or copper with excellent self-lubricating properties to reduce the wear of the second through gauge and extend its service life. The first bushing is embedded in the first through hole by interference fit, and the first through hole and the support block are staggered to avoid interference with the use of the second through gauge. The surface of the second through gauge is processed with / embedded with a key, and a keyway is processed in the first bushing. The keyway is open at one end close to the ship-shaped plate and not open at the other end. The second through gauge is connected to a second handle at the end facing away from the ship-shaped plate. Through the setting of the second handle and the key, the second through gauge cannot be removed to avoid damage caused by bumps, etc. When the second through gauge needs to be calibrated or replaced, the second handle is removed and the second through gauge can be taken out from the inside of the first mounting seat.

[0038] For example, see Figure 1 and Figure 6 As shown, the second mounting seat 42 is provided with a third through hole and a fourth through hole respectively perpendicular to the corresponding ship-shaped plate, the third through hole is provided with a second bushing for accommodating the passage of the third through gauge 44, and the fourth through gauge 45 is slidably provided in the fourth through hole.

[0039] In this technical solution, the third through gauge and the fourth through gauge are respectively connected to the third handle and the fourth handle to avoid direct contact with the third through gauge and the fourth through gauge. The structure of the second bushing can refer to the first bushing.

[0040] For example, see Figure 1 and Figure 6 As shown, the cross section of the fourth through gauge 45 is an arc-shaped structure, and a limiting groove 451 is provided on its outer wall, and a limiting column corresponding to the limiting groove is provided in the second mounting seat 42 .

[0041] In this technical solution, the fourth through gauge has an arc-shaped structure, and conventional bushings are not applicable, so a limit groove is processed on its surface, and a steel ball top screw is provided in the second mounting seat as a limit column, and the end of the limit column is in the limit groove to prevent the fourth through gauge from falling off the second mounting seat.

[0042] For example, see Figure 1 and Figure 3 As shown, the top of the support base 5 is provided with a fifth through gauge 51 and a sixth through gauge 52 corresponding to the bottom plate.

[0043] In this technical solution, one end of the fifth and sixth through gauges are respectively embedded in the support seat, and the other end protrudes from the top surface of the support seat and is arranged corresponding to the holes in the base plate, thereby improving the positioning accuracy of the base plate, that is, improving the accuracy of detection, and at the same time, detecting the hole positions in the base plate. Among them, the number of sixth through gauges is two, and they are arranged diagonally.

[0044] For example, see Figure 1 and Figure 3 As shown, one end of the pressure rod 64 is connected to the mounting arm through a threaded connection, and the other end is connected to a buffer pad.

[0045] In this technical solution, the connecting arm of the clamping block is adjustably connected to the quick-clamp clamp through conventional bolts, nuts and gaskets to adjust the position of the pressure rod acting on the base plate to avoid interference, etc. The pressure rod is adjustably connected to the mounting arm through a threaded connection to adjust the installation height of the pressure rod to ensure that the pressure rod acts on the top surface of the base plate, and the buffer pad can prevent the pressure rod from leaving marks on the surface of the base plate.

[0046] In summary, the welding inspection fixture of the ship-shaped metal part has a simple structure, is used for inspection of the ship-shaped metal part after welding, is clamped once, is easy to operate, and can simultaneously inspect the relative position accuracy between multiple holes.

[0047] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.

[0048] The above description is only a specific implementation of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
