DETAILED DESCRIPTION

[0021] The embodiments of the present application will be described in detail with specific examples, and other advantages and effects of the present application can be easily understood by those skilled in the art from the contents disclosed in the present specification. The present application can also be implemented or applied in other different embodiments, and each detail in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the drawings provided in the following embodiments are only used to illustrate the basic concept of the present application, and the following embodiments and features in the embodiments can be combined with each other without conflict.

[0022] Please refer to Figs. 1-2 In the embodiment, a manual stud welding self-positioning device is disclosed, which comprises a guide sleeve assembly 1 provided with a guide hole 11a, and a positioning sleeve 2 provided with an elastic deformation part 20 capable of being deformed under force and a welding gun connecting part 21 for connecting with a welding gun 3. The elastic deformation part 20 can abut against the inner wall of the guide hole 10a after being deformed to limit the radial position of the positioning sleeve 2. It can be understood that the guide hole 11a is used for guiding the welding gun 3 during the manual stud welding process, and the positioning sleeve 2 is pluggably arranged in the guide hole 11a. The specific structure of the elastic deformation part 20 is not limited here, as long as it can be deformed and abut against the hole wall of the guide hole 11a after being subjected to force. The specific structure of the welding gun connecting part 21 is not limited here, as long as it is beneficial to connecting with the welding gun 3.

[0023] The manual stud welding self-positioning device in the structural design can effectively solve the problem of unstable positioning or difficult operation of the welding gun 3 caused by the gap between the welding gun 3 and the tool guide sleeve. Specifically, during use, the positioning sleeve 2 can be connected to the welding gun 3 first, and then the positioning sleeve 2 is inserted into the guide hole 11a and a certain pressure is applied to deform the elastic deformation part 20 (when in use, the positioning sleeve 2 is pressed against the workpiece sheet metal part, and the pressure can be applied manually). After the elastic deformation part 20 is deformed, it cooperates with the guide hole 11a to achieve radial positioning of the positioning sleeve 2, that is, radial self-positioning of the welding gun 3 (to prevent the welding gun 3 from tilting and shaking). This effectively reduces the requirement for the gap between the positioning sleeve 2 and the guide hole 11a, and the guide hole 11a can be designed to be slightly larger. This can also achieve stable positioning of the welding gun 3, prevent the welding gun from shaking, ensure the quality of stud welding, and facilitate the insertion of the welding gun 3. At the same time, after welding is completed and the pressure is released, the elastic deformation part 20 can automatically recover, which facilitates the removal of the welding gun 3 and facilitates operation.

[0024] In the embodiment, the elastic deformation part 20 is an annular protruding part integrally formed on the positioning sleeve 2 and protruding radially outward from the positioning sleeve 2, and the annular protruding part is uniformly provided with a plurality of separation slots 20a in the circumferential direction. In actual processing, the separation slots 20a can be processed first, and then the annular protruding part can be formed by pressing. Alternatively, the annular protruding part can be formed by mold processing, and then the separation slots 20a can be processed. The elastic deformation part 20 in this structural design has good overall strength and good durability. The annular protruding part facilitates reliable cooperation with the guide hole 11a and ensures reliable positioning of the positioning sleeve.

[0025] In the embodiment, the positioning sleeve 2 includes a positioning sleeve upper section 22 and a positioning sleeve lower section 23, and the elastic deformation part 20 includes a plurality of elastic sheets 201 uniformly arranged in the circumferential direction of the positioning sleeve 2. The two ends of the elastic sheet 201 are fixedly connected to the positioning sleeve upper section 22 and the positioning sleeve lower section 23, respectively. Specifically, the two ends of the elastic sheet 201 can be fixedly connected to the positioning sleeve upper section 22 and the positioning sleeve lower section 23 by laser welding. In this structural design, the positioning sleeve upper section 22 and the positioning sleeve lower section 23 are connected by the elastic sheets 201. The elastic sheets 201 can be processed separately, which is convenient and can save manufacturing costs. At the same time, by using a plurality of elastic sheets 201 arranged uniformly, the overall structure has good deformation effect, and the reliability and durability can be guaranteed.

[0026] In the embodiment, the elastic sheet 201 has an arc-shaped part 201a protruding radially outward from the positioning sleeve 2. By providing the arc-shaped part 201a protruding radially outward from the positioning sleeve 2, the contact area between the elastic sheet 201 and the hole wall of the guide hole 11a can be relatively large, thereby improving the reliability of the positioning of the positioning sleeve 2. This can ensure that the elastic sheet 201 has a long fatigue life and further improve the durability.

[0027] In this embodiment, the elastic sheet 201 is a spring steel elastic sheet. By using spring steel material, the elastic deformation capability is good, which is conducive to further improving the overall durability of the device. In the design, the elastic sheet 201 does not need to be designed to be too thick. Generally, a thickness of 0.5mm-2mm is sufficient to ensure the elastic deformation effect.

[0028] In this embodiment, the welding gun connection part 21 includes a threaded connection hole 21a disposed on the top of the positioning sleeve 2; the structure of the threaded connection hole 21a is simple to process and the connection is convenient and reliable; in specific processing, the section with the threaded connection hole 21a can be a separately designed section and welded to the positioning sleeve 2 body.

[0029] In this embodiment, the guide sleeve assembly 1 includes a fixed base 10 and a guide sleeve 11 detachably connected to the fixed base 10, and the guide hole 11a is provided on the guide sleeve 11. In use, the fixed base 10 is usually fixedly installed on the workbench. Here, the guide sleeve 11 is fixedly installed on the fixed base 10 by screws. The detachable connection method facilitates the replacement and maintenance of the guide sleeve 11.

[0030] In this embodiment, the fixed base 10 is provided with a mounting hole 10a, and the inner sleeve of the guide sleeve 11 is disposed in the mounting hole 10a. By disposing the inner sleeve of the guide sleeve 11 in the mounting hole 10a, it is beneficial to ensure the positional accuracy of the guide sleeve 11 during disassembly and assembly, and at the same time, the installation stability is high.

[0031] In this embodiment, the mounting hole 10a is provided with a first notch 10b, and the guide hole 11a is provided with a second notch 11b corresponding to the first notch 10b. By correspondingly providing the first notch 10b and the second notch 11b, it is convenient to observe the welding situation and the deformation of the elastic deformation part 20 through the notch. At the same time, it can also reduce the overall volume and avoid interference with other structures on the welded workpiece.

[0032] In this embodiment, the guide sleeve 11 is a copper alloy guide sleeve. By using a copper alloy guide sleeve, the guide sleeve 11 has good lubricity and wear resistance, which helps to further improve the overall durability of the device.
