Technical Field

[0001] The utility model relates to the technical field of cylinder welding, in particular to a cylinder welding tool. Background Art

[0002] During the production process of hydraulic cylinders, it is often necessary to weld various parts on the outside of the cylinder body, such as joints, pipes, connecting ears, etc. These parts are usually arranged relative to each other. Therefore, during the welding process, it is difficult and imprecise to maintain the relative welding positions of the parts. Therefore, welding devices are usually used for positioning in the prior art. For example, the patent with publication number CN209319091U discloses a hydraulic cylinder welding device. Specifically, it adopts a pair of semicircular structures to form a connecting fixture, which is connected to the hydraulic cylinder through a limit groove and a limit block. The position of the hydraulic cylinder in the connecting fixture is fixed by the mutual cooperation between the limit groove and the limit block; however, it can only fix the hydraulic cylinder body. In fact, the welding positioning of the relative positions of parts on the outer wall of the cylinder body has not yet been solved.

[0003] Based on the above description, there is an urgent need for a welding tool that is convenient for confirming the relative welding position on the outer wall of the cylinder body. Utility Model Content

[0022] See also Figures 1 to 4 The utility model provides the following technical solutions: a cylinder welding tool, which is suitable for the relative welding of the outer parts of the hydraulic cylinder.

[0023] Specifically, if Figure 1 and Figure 4 As shown, a cylinder welding tool includes a pair of support components 1 and a pair of positioning components 2; the positioning component 2 includes a fixed ring groove 21, a ring plate 22, and a pair of positioning members 23; the outer edge of the ring plate 22 is embedded in the groove cavity of the fixed ring groove 21 and is rotatably connected to the fixed ring groove 21; the inner part of the ring plate 22 near the center of the circle passes through the fixed ring groove 21 and is connected to the outer side wall of the fixed ring groove 21 through the positioning member 23; a pair of positioning members 23 are arranged on the annular surface of the ring plate 22 relative to each other; the bottom of the fixed ring groove 21 is connected to the support component 1.

[0024] The specific implementation process is: a pair of positioning assemblies 2 are supported by a pair of support assemblies 1, and then the two ends of the hydraulic cylinder body are supported and positioned by a pair of support assemblies 1 and a pair of positioning assemblies 2; specifically, the end of the cylinder body passes through the ring plate 22 and is limited by the ring plate 22. Since the outer edge of the ring plate 22 is embedded in the groove cavity of the fixed ring groove 21 and is rotatably connected to the fixed ring groove 21, the rotation adjustment of the outer position of the cylinder body can be achieved by rotating the adjustment ring plate 22. After the cylinder body is adjusted, it is positioned and fixed by the positioning member 23. Further, since a pair of positioning members 23 are relatively arranged on the annular surface of the ring plate 22, the position of the cylinder body can be adjusted by rotating the ring plate 22, and the positions of the two weldings are positioned as relative positions by the relative pair of positioning members 23, thereby ensuring the relativity and accuracy of the welding positions.

[0025] Specifically, if Figure 4 As shown, a plurality of balls 3 are arranged in the fixed ring groove 21 ; the outer edge of the ring plate 22 is embedded in the groove cavity of the fixed ring groove 21 and contacts the balls 3 .

[0026] In this embodiment, the use of the balls 3 makes it easier for the ring plate 22 to drive the cylinder body to rotate and adjust easily, saving time and effort.

[0027] Specifically, if Figure 1 and Figure 4 As shown, an operating handle 4 is provided on one end surface of the ring plate 22 passing through the fixed ring groove 21 ; the operating handle 4 is connected to the fixed ring groove 21 through a positioning member 23 .

[0028] In this embodiment, the operating handle 4 facilitates manual rotation of the ring plate 22 and the cylinder body mounted between the pair of ring plates 22 . In addition, it also serves as an extension of the positioning member 23 .

[0029] Specifically, if Figure 1 and Figure 3 As shown, an infrared emitter 5 is provided on a side of the fixing ring groove 21 away from the operating handle 4 .

[0030] In this embodiment, an infrared emitter 5 is provided on the side of the fixed ring groove 21 away from the operating handle 4. The infrared emitter 5 is specifically arranged opposite to the positioning member 23. Then, after the positioning member 23 is positioned, the infrared rays emitted by the infrared emitter 5 are used to confirm the specific welding position after positioning, thereby ensuring the accuracy of the welding position.

[0031] Specifically, if Figure 1 and Figure 3 As shown, it also includes multiple clamping components 6; the clamping components 6 are provided with welding grooves 61 opposite to each other; a pair of groove side walls of the welding groove 61 are each provided with a light hole 62; the opening end of the light hole 62 corresponds to the emitting end of the infrared emitter 5.

[0032] In this embodiment, the clamping assembly 6 includes a pair of semicircular ring plates that are detachably connected by bolts. The semicircular ring plates are respectively provided with welding grooves 61. The two welding grooves 61 are arranged opposite to each other. The welding grooves 61 can accurately confirm the welding area, and the welding grooves 61 use infrared rays to simultaneously pass through multiple straight-line directions of light holes 62 to confirm their precise positions, thereby fully ensuring the accuracy of the welding position after each positioning.

[0033] Specifically, if Figure 3 and Figure 4 As shown, the positioning member 23 includes a hinge 231 and a lever 232 ; the lever 232 is connected to the operating handle 4 via the hinge 231 ; and the operating handle 4 is connected to the fixed ring groove 21 via the lever 232 .

[0034] In this embodiment, the direction of the harness 232 is adjusted by the hinge 231 to achieve positioning. The harness 232 can be a buckle or a pair of plates connected by magnetic attraction. A through hole for the threaded column to pass through can be further provided on the buckle or the plate, and it can be limited and stopped by a nut.

[0035] Specifically, if Figure 1 As shown, a connecting arc plate is provided at the bottom of the fixed ring groove 21; the support assembly 1 includes a bottom plate and a support seat; and a limiting groove for the connecting arc plate to be embedded is provided at the top of the support seat.

[0036] In this embodiment, the connection between the fixed ring groove 21 and the support seat can be achieved by embedding the connecting arc plate into the limiting groove, and the bottom plate can ensure that the support seat is not easy to tip over after the cylinder body is erected.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
