[0029] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0033] In related technologies, hydraulic cylinders need to be welded to the boom to ensure the normal operation of the hydraulic cylinders. However, during the welding process, it is impossible to effectively fix the relative positions of the hydraulic cylinders and boom, making it easy for them to shift during welding. This greatly increases the difficulty of the welding connection and also makes it impossible to guarantee the accuracy of the welding connection along the axial direction of the hydraulic cylinders.

[0034] To solve the above problems, such as Figures 1-3 As shown, this embodiment provides a hydraulic cylinder welding auxiliary device, which includes a support assembly 1, a hydraulic cylinder positioning component 2, and a boom positioning component 3. The support assembly 1 includes a base plate 11, a first support component 12, and a second support component 13. Both the first support component 12 and the second support component 13 are disposed on the base plate 11. The first support component 12 is used to support the hydraulic cylinder 20, and the second support component 13 is used to support the boom 30 welded to the hydraulic cylinder 20. The hydraulic cylinder positioning component 2 passes through the positioning hole 201 on the hydraulic cylinder 20 and is inserted into the base plate 11. The boom positioning component 3 is disposed on the base plate 11 and abuts against the boom 30 to position the relative position of the boom 30 with respect to the axial direction of the hydraulic cylinder 20. The hydraulic cylinder welding auxiliary device provided in this embodiment achieves positioning and support of the hydraulic cylinder 20 by setting a first support member 12 and a hydraulic cylinder positioning member 2. It also achieves support of the boom 30 by setting a second support member 13. Furthermore, the boom positioning component 3 limits the relative position of the boom 30 with respect to the hydraulic cylinder 20 in the axial direction, preventing misalignment between the hydraulic cylinder 20 and the boom 30. This not only facilitates the welding connection operation between the hydraulic cylinder 20 and the boom 30 but also improves the accuracy of the welding connection along the axial direction of the hydraulic cylinder 20. It should be noted that in this embodiment, the axial end of the hydraulic cylinder 20 is inserted into the mounting hole of the boom 30 and welded therein. Optionally, in this embodiment, the hydraulic cylinder 20 can be a hydraulic cylinder.

[0035] Optionally, in this embodiment, as Figure 1 As shown, a positioning hole 111 is provided on the base plate 11. The cylinder positioning component 2 includes a positioning pin, which passes through the positioning hole 201 on the cylinder 20 and is inserted into the positioning hole 111. The above configuration effectively ensures the reliability of positioning the cylinder 20, avoids displacement in the axial direction and rotation in the circumferential direction of the cylinder 20, and has a simple structure and is easy to operate.

[0036] Optionally, in this embodiment, as Figure 1As shown, the first support member 12 includes at least two first support blocks 121 spaced apart along the axial direction of the hydraulic cylinder 20. Both first support blocks 121 are disposed on the base plate 11, and each first support block 121 has a supporting groove 1211 for supporting the hydraulic cylinder 20. This structural arrangement of the first support member 12 effectively ensures the stability of the hydraulic cylinder 20 and has a simple structure. In other embodiments, the specific number of first support blocks 121 can be adaptively adjusted according to the axial extension length of the hydraulic cylinder 20.

[0037] Optionally, in this embodiment, as Figure 1 As shown, the support groove 1211 is V-shaped. By designing the support groove 1211 as V-shaped, not only is the stability of the support groove 1211 in supporting the hydraulic cylinder 20 guaranteed, but the support groove 1211 can also be adapted to hydraulic cylinders 20 with different outer diameters, thus improving the applicability of the first support block 121.

[0038] In this embodiment, as Figures 1-3 As shown, the boom positioning assembly 3 includes a first positioning member 31 and a second positioning member 32. The first positioning member 31 and the second positioning member 32 are arranged opposite to each other and spaced apart along the axial direction of the hydraulic cylinder 20. Both the first positioning member 31 and the second positioning member 32 are disposed on the base plate 11. The boom 30 is located between the first positioning member 31 and the second positioning member 32. The boom 30 has a first sidewall 301 and a second sidewall 302 opposite to each other along the axial direction of the hydraulic cylinder 20. The first positioning member 31 elastically abuts against the first sidewall 301, and the second positioning member 32 abuts against the second sidewall 302. The above-mentioned structural design of the boom positioning assembly 3 enables the first positioning member 31 to generate a certain elastic pushing force on the boom 30, causing the second sidewall 302 of the boom 30 to abut against the second positioning member 32, thereby defining the relative position of the boom 30 with respect to the axial direction of the hydraulic cylinder 20. Furthermore, by elastically abutting the first positioning member 31 against the first sidewall 301, the boom positioning assembly 3 can position booms 30 of different thicknesses in the axial direction of the cylinder 20, thus improving the applicability of the boom positioning assembly 3. Optionally, in this embodiment, the second positioning member 32 is in the form of a positioning plate.

[0039] Optionally, in this embodiment, at least two boom positioning components 3 are spaced apart on the base plate 11 along the extension direction of the boom 30 (i.e., the radial direction of the cylinder 20). These at least two boom positioning components 3 work together to position the boom 30, preventing it from shifting in its extension direction. Alternatively, in this embodiment, two boom positioning components 3 are spaced apart on the base plate 11 along the extension direction of the boom 30. In other embodiments, the number of boom positioning components 3 arranged along the extension direction of the boom 30 can be set according to requirements.

[0040] Optionally, in this embodiment, the first positioning member 31 includes a positioning plate and an elastic member. The positioning plate is disposed on the base plate 11, the first end of the elastic member is connected to the positioning plate, and the second end of the elastic member elastically abuts against the first sidewall 301. The above-described structural design of the first positioning member 31 ensures that the first positioning member 31 elastically abuts against the first sidewall 301. Specifically, in this embodiment, the elastic member includes a spring and abutting ball. The first end of the spring is connected to the positioning plate, the second end of the spring is connected to the abutting ball, and the abutting ball elastically abuts against the first sidewall 301. In other embodiments, the elastic member can also be directly designed as a spring.

[0041] In this embodiment, as Figure 1 and Figure 3 As shown, the two ends of the boom 30 extending radially along the cylinder 20 are a support end 303 and a welding end 304, respectively. The second support member 13 is used to support the support end 303. The cylinder welding auxiliary device also includes a height adjustment component 4, which includes a lifting rod 41 and a limiting member 42. The axial extension length of the lifting rod 41 is adjustable. The bottom end of the lifting rod 41 is fixedly connected to the base plate 11, and the top end of the lifting rod 41 abuts against the bottom of the welding end 304. The limiting member 42 is disposed on the base plate 11 and abuts against the upper end face of the welding end 304. With the above configuration, by adjusting the axial extension length of the lifting rod 41, the height position of the welding end 304 is adjusted, ensuring that the limiting member 42 abuts against the upper end face of the welding end 304, thereby positioning the height of the welding end 304 and ensuring the relative position of the welding end 304 and the cylinder 20 in the height direction, thus ensuring the accuracy of the welding connection between the welding end 304 and the cylinder 20 in the height direction. Optionally, in this embodiment, the lifting rod 41 is a telescopic rod. Since the specific structure for axial extension and retraction adjustment of the telescopic rod is prior art, it will not be described in detail here. Optionally, in this embodiment, the second support member 13 is in the form of a support plate.

[0042] Optionally, in this embodiment, a support groove 3041 is provided at the bottom of the welding end 304, and the top end of the lifting rod 41 is located in the support groove 3041 and abuts against the top wall of the support groove 3041. The above arrangement effectively ensures the stability and reliability of the abutment between the lifting rod 41 and the bottom of the welding end 304.

[0043] In this embodiment, as Figure 1 As shown, the limiting member 42 includes a mounting plate 421 and a limiting plate 422 connected to each other. The mounting plate 421 is disposed on the base plate 11, and the limiting plate 422 abuts against the upper end face of the welding end 304. The structure of the limiting member 42 is simple.

[0044] In this embodiment, as Figures 1-3As shown, both ends of the hydraulic cylinder 20 are welded to the upper arm 30 in the axial direction. The hydraulic cylinder welding auxiliary device also includes a reinforcing rod assembly 5, which includes two welded reinforcing rods 51. Both welded reinforcing rods 51 extend along the axial direction of the hydraulic cylinder 20. The first end of one welded reinforcing rod 51 is welded to the upper end face of one of the upper arms 30, and the second end of one welded reinforcing rod 51 is welded to the upper end face of the other upper arm 30. The first end of the other welded reinforcing rod 51 is welded to the lower end face of one of the upper arms 30, and the second end of the other welded reinforcing rod 51 is welded to the lower end face of the other upper arm 30. By setting up the reinforcing rod assembly 5, the welding fixation between the two upper arms 30 is achieved, effectively preventing the upper arms 30 from deforming due to the high temperature of welding and ensuring the reliability of the structure. It should be noted that after the upper arm 30 and the hydraulic cylinder 20 are firmly welded together, the welded reinforcing rods 51 welded to the upper arm 30 can be removed.

[0045] In this embodiment, as Figures 1-3 As shown, the hydraulic cylinder welding auxiliary device also includes a positioning rod assembly 6. The positioning rod assembly 6 includes at least two positioning rods 61 spaced apart along the axial direction of the hydraulic cylinder 20. The positioning rods 61 are disposed on the base plate 11, and the outer peripheral walls of at least two positioning rods 61 abut against the outer peripheral wall of the welding reinforcing rod 51. By setting the positioning rod assembly 6, the position of the welding reinforcing rod 51 is positioned, ensuring the parallelism between the welding reinforcing rod 51 and the hydraulic cylinder 20. In this embodiment, the positioning rod assembly 6 includes two positioning rods 61 spaced apart along the axial direction of the hydraulic cylinder 20. In other embodiments, the number of positioning rods 61 in the positioning rod assembly 6 can be adjusted according to requirements.

[0046] Optionally, the hydraulic cylinder welding auxiliary device includes at least two positioning rod assemblies 6, which are arranged at intervals along the extension direction of the boom 30. Each positioning rod assembly 6 is correspondingly provided with a reinforcing rod assembly 5, further ensuring the stability of the boom 30 structure. In this embodiment, the hydraulic cylinder welding auxiliary device includes two positioning rod assemblies 6. In other embodiments, the specific number of positioning rod assemblies 6 can be set according to requirements.
