Description

Technical Field

[0001] The utility model relates to the technical field of mechanical component welding detection, in particular to an adjustable pressure device for mechanical component welding. Background Art

[0002] Welding of mechanical components is a manufacturing process that permanently joins two or more metal parts by heating them to a molten state, then cooling and solidifying them. Welding is widely used in machinery manufacturing, construction, shipbuilding, aerospace, and automotive manufacturing.

[0003] When welding mechanical structural components such as plates and pipes, problems such as weld misalignment after welding often occur. Weld misalignment after welding means that the deviation between the weld and the designed position exceeds the specified range during the welding process. This situation may affect the structural strength and sealing of the welded parts. Misaligned welds may occur for the following reasons: 1. Inaccurate welding operation: Insufficient operating skills of the welder may cause the weld position to deviate from the predetermined position, such as improper rod feeding method, incorrect rod angle or uneven welding speed; 2. Welding equipment problems: If the welding equipment used is unstable or unqualified, it may affect the stability of the welding process, resulting in misaligned welds; 3. Poor quality of welding materials: Poor quality of welding materials such as welding rods or welding wires may affect the welding process and the formation of welds; 4. Improper selection of welding process parameters: Welding current is too large or too small, welding speed is too fast or too slow, and arc length is inappropriate, which may all lead to misaligned welds; 5. Inaccurate weldment assembly: Before welding, if the weldment is not assembled accurately, such as uneven docking or gaps, it may also cause misaligned welds; 6. Welding environment factors: The temperature, humidity and other conditions of the welding environment do not meet the requirements, which may also affect the welding quality and lead to misaligned welds.

[0004] All of the above factors can lead to misaligned welds after welding. Furthermore, during the welding process, mechanical structural components such as plates and pipes often need to be clamped and fixed. The choice of clamping fixtures can also affect the post-weld results. Currently, clamping fixtures used in the welding of mechanical components often cannot display pressure values and cannot evenly adjust the pressure, making operation inconvenient, affecting the user experience and the welding results, and hindering the promotion and application of such clamping fixtures in the field of welding technology.

However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0029] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings.

[0030] like Figures 1 to 7As shown, an adjustable pressure device for welding mechanical parts mainly consists of a transmission element 1, a transmission connector 2, a transmission element mounting seat 3, a locking plate 7, a pressure connector 8, a pressure sensor 9, and a pressure plug 10. The transmission connector 2 is mounted on the outside of the transmission element 1. The transmission element 1 passes through the through hole of the transmission element mounting seat 3, that is, the transmission element 1 extends from one side of the transmission element mounting seat 3 to the other side of the transmission element mounting seat 3. The locking plate 7, the pressure connector 8, the pressure sensor 9, and the pressure plug 10 are sequentially arranged at one end of the transmission element 1. The pressure sensor 9 is a calibrator with a built-in digital display function. This embodiment provides a transmission element 1, a transmission connector 2, a transmission element mounting seat 3, a locking plate 7, a pressure connector 8, a pressure sensor 9 and a pressure head 10. In actual use, a manual wrench or an electric wrench is used to provide a torque to rotate the above-mentioned transmission element 1. The transmission connector 2 is installed on the transmission element 1 and the transmission element mounting seat 3 at the same time, so that the linear displacement of the transmission element 1 can be converted into axial pressure and transmitted to the pressure sensor 9 and the pressure head 10. The pressure sensor 9 is a calibrator with a built-in digital display function, which can collect and display pressure data, making it convenient for the operator to check the pressure size and adjust the pressure size, so that mechanical structural components such as plates and pipes can be compressed and fixed while achieving adjustable pressure, reducing the probability of quality problems such as weld misalignment, ensuring welding quality, enhancing user experience, and being conducive to the promotion and application of the above-mentioned adjustable pressure device for welding mechanical components in the market.

[0031] The transmission element 1 is a ball screw. The ball screw replaces traditional sliding friction with rolling friction, thereby achieving high-efficiency and high-precision transmission. It can accurately transmit the rotational force provided by tools such as manual wrenches or electric wrenches to the pressure sensor 9 and the pressure head 10. The ball screw has high rigidity and can withstand large loads without losing stability. At the same time, the rolling of the balls reduces frictional resistance, has a long service life, and can effectively reduce the user's cost of use. Specifically, the ball screw includes a screw body 1-1. One end of the screw body 1-1 is an operating end 1-2. The operating end 1-2 can be a hexagonal connecting column so that a manual wrench or electric wrench can be mounted on the connecting column to reduce the probability of slippage, thereby ensuring safety during use. The other end of the screw body 1-1 is a stepped mounting portion 1-3. The locking plate 7 and the pressure connector 8 can be mounted on the stepped mounting portion 1-3 to prevent the locking plate 7 and the pressure connector 8 from slipping on the screw body 1-1. The above-mentioned transmission connecting part 2 is a screw nut, which is installed outside the ball screw and connected to the above-mentioned transmission element mounting seat 3 through bolts. The ball screw and the screw nut constitute a ball screw motion pair, and the screw nut is installed on the above-mentioned transmission element mounting seat 3 through bolt connection.

[0032] In order to reduce the resistance of the ball screw during force transmission, the above-mentioned pressure connector 8 in this embodiment includes a connector connection part 1 8-1 and a connector connection part 2 8-2. A step hole is formed inside the above-mentioned connector connection part 1 8-1, and a thrust ball bearing 11 is installed at the step hole. The outer ring of the above-mentioned thrust ball bearing 11 supports the above-mentioned step hole, and the above-mentioned pressure connector 8 is connected to the above-mentioned locking plate 7 by bolts. That is, when the thrust ball bearing 11 is installed in the step hole, the above-mentioned locking plate 7 can prevent the above-mentioned thrust ball bearing 11 from sliding out, thereby fixing the installation position of the thrust ball bearing 11. Specifically, the inner hole of the thrust ball bearing 11 cooperates with the stepped shaft at the top pressure shaft end of the ball screw, and the step at the top pressure shaft end of the ball screw presses against the shaft ring of the thrust ball bearing 11. Then, through the stepped hole formed inside the connecting part 8-1 of the above-mentioned connector, the outer ring of the thrust ball bearing 11 presses against the stepped hole inside the pressure connector 8. Then, the ball screw can transmit the rotational force provided by tools such as a manual wrench or an electric wrench to the pressure sensor 9 and the pressure head 10 through the thrust ball bearing 11 and the pressure connector 8.

[0033] To facilitate connection with the pressure sensor 9 and achieve both force transmission and force display, the second connector portion 8-2 is provided with a connection hole 8-3. One end of the pressure sensor 9 is embedded in the connection hole 8-3, and the other end of the pressure sensor 9 is connected to the pressure plug 10. To facilitate disassembly of the pressure sensor 9, the connection hole 8-3 in this embodiment is a threaded hole, one end of the pressure sensor 9 is a threaded section, and the pressure sensor 9 is threadedly connected to the connection hole 8-3. Similarly, to reduce the difficulty of assembling the pressure sensor 9 and the pressure plug 10, the other end of the pressure sensor 9 is designed as a threaded section, and the pressure plug 10 has a plug threaded hole 10-1, and the pressure sensor 9 is threadedly connected to the pressure plug 10.

[0034] In order to ensure the stability of the connection between the locking plate 7 and the pressure connector 8 and to prevent the thrust ball bearing 11 from shifting, the locking plate 7 and the pressure connector 8 are fixedly connected by bolts.

[0035] In order to facilitate the adjustment of the position of the adjustable pressure device for welding the above-mentioned mechanical parts, thereby realizing the clamping operation and pressure detection of the clamped parts at any position in the longitudinal direction, the adjustable pressure device in this embodiment is also provided with a fixed mounting seat 4, the above-mentioned fixed mounting seat 4 is provided with a mounting seat slide 4-1, the side of the above-mentioned mounting seat slide 4-1 is installed with a slide rail 6, the above-mentioned slide rail 6 is installed with a slider 5, and the above-mentioned transmission element mounting seat 3 is installed on the above-mentioned slider 5. Specifically, the above-mentioned fixed mounting seat 4 is in the shape of a long plate, and the above-mentioned mounting seat slide 4-1 is arranged along the height direction of the above-mentioned fixed mounting seat 4. By changing the position of the above-mentioned transmission element mounting seat 3 on the slider 3, the clamping position of the pressure head 10 is changed, thereby expanding the scope of use. In this embodiment, there are multiple mounting seat slides 1-1. Correspondingly, multiple adjustable pressure devices for welding can be provided to simultaneously perform welding operations on different parts of the clamping parts, thereby improving work efficiency.

[0036] In this embodiment, an adjustable pressure device for welding mechanical components has an ingenious structure and is easy to operate. By arranging a transmission element 1, a transmission connector 2, a transmission element mounting seat 3, a locking plate 7, a pressure connector 8, a pressure sensor 9 and a pressure head 10, in actual use, a manual wrench or an electric wrench is used to provide a torque to rotate the above-mentioned transmission element 1 (which can be a ball screw). The transmission connector 2 (screw nut) is installed on the transmission element 1 and the transmission element mounting seat 3 at the same time, so that the linear displacement of the transmission element 1 can be converted into axial pressure and transmitted to the pressure sensor 9 and the pressure head 10. The pressure sensor 10 is a calibrator with a built-in digital display function, which can collect and display pressure data, making it convenient for the operator to view the pressure size and adjust the pressure size, thereby realizing pressure adjustment while pressing and fixing mechanical structural components such as plates and pipes, reducing the probability of quality problems such as weld misalignment, ensuring welding quality, and enhancing user experience, which is conducive to the promotion and application of the above-mentioned adjustable pressure device for welding mechanical components in the market.
