Description

Technical Field

[0001] This utility model belongs to the field of welding equipment, and specifically relates to a centering device for welding molds. Background Technology

[0002] A welding mold alignment device is an auxiliary device specifically designed for laser welding machines, primarily used to ensure accurate alignment and positioning of different molds or workpieces during the welding process. Current welding mold alignment devices have some drawbacks. First, due to the lack of an effective fixing structure, instability may occur during alignment. When the alignment device is in operation, it needs to precisely align and weld different molds, but the lack of a fixing structure makes the molds susceptible to slight displacement due to external forces after alignment, thus affecting welding accuracy. This drawback is mainly because the alignment device design did not consider sufficient fixing measures, or sacrificed some stability for flexibility. The conventional solution is for operators to operate more carefully, minimizing unnecessary external force interference to the molds after alignment, and constantly monitoring the mold's position during welding. However, the drawback of this method is that it relies heavily on the experience and attention of the operators. Once the operators are negligent, it is easy to cause inaccurate centering, which increases the workload and mental stress of the operators. At the same time, it cannot fundamentally solve the problem of instability of the centering device itself, which increases the uncertainty in the production process and reduces the production efficiency and product quality stability. Therefore, a new structure is needed to solve the above technical problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a centering device for welding molds, which solves the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a welding mold centering device, comprising: a base assembly, a fixing assembly, and an alignment assembly. The base assembly includes: a base body, a base plate one, and a base plate two. The base plate one is mounted on the upper surface of the base body, and two base plates two are mounted on the upper surface of the base plate one. The fixing assembly includes: a fixing seat, an electric push rod one, a hinge, a fixing block, and a fixing plate. The electric push rod one is mounted on the outer surface of the fixing seat, and the telescopic rod of the electric push rod one passes through the fixing seat. The inner end of the telescopic rod is mounted on a fixing block through a hinge. The lower surface of the fixing block is mounted on a fixing plate through a spring post. The alignment assembly includes: a central shaft, a mounting plate, an electric push rod two, and a pushing block. The mounting plate is mounted on the upper surface of the base plate one, and the electric push rod is mounted on the inner surface of the mounting plate. The telescopic end of the electric push rod two is mounted on a pushing plate. The central shaft is mounted above the two base plates two.

[0005] In a preferred embodiment, a base plate 1 is installed at the center of the upper surface of the base body, and two base plates 2 are symmetrically installed on the upper surface of the base plate 1. A gap is provided between the two base plates 2, and the central axis of the gap is collinear with the central axis of the base plate 1. A fixing seat is symmetrically installed on the left and right edges of the upper surface of the base plate 1.

[0006] In a preferred embodiment, an electric push rod is mounted on the outer surface of the fixing base, and a telescopic rod is movably mounted on the inner surface of the fixing base via the electric push rod. A hinge is hinged to the end of the telescopic rod away from the fixing base, and a fixing block is hinged to the lower surface of the hinge. A spring post is movably mounted on the lower surface of the fixing block. During use, after alignment, the welded object may experience slight displacement due to minor external vibrations or other disturbances. The electric push rod in the fixing assembly pushes the fixing block and the fixing plate to firmly fix the welded object to the upper surface of the base plate, ensuring that it remains in the correct position throughout the welding process, thus greatly improving the welding accuracy.

[0007] In a preferred embodiment, a fixing plate is installed at the end of the spring column away from the fixing block. The lower surface of the fixing plate abuts against the upper surface of the base plate 2 via an electric push rod 1. A mounting plate is symmetrically installed on the left and right edges of the upper surface of the base plate 1. An electric push rod 2 is installed at the center of the inner surface of the mounting plate.

[0008] In a preferred embodiment, the electric push rod 2 passes through the fixed base, and a push block is installed at the end of the electric push rod 2 away from the mounting plate. The lower surface of the push block abuts against the upper surface of the base plate 2.

[0009] In a preferred embodiment, the central shaft component includes: an electric push rod three and a center block. The center block is mounted on the top of the two base plates two via the electric push rod three. The central axis of the center block is collinear with the central axis of the two base plates two. In use, the central shaft component serves as an alignment reference, providing a clear reference point for the alignment of the two welded objects. The electric push rod two on the inner surface of the mounting plate pushes the push block, which can precisely adjust the position of the mold so that it is aligned around the central shaft component, ensuring that the two molds can achieve highly accurate alignment in all directions.

[0010] After adopting the above technical solution, the beneficial effects of this utility model are as follows: by setting a fixing component, which includes a fixing base, an electric push rod, a hinge, a fixing block, and a fixing plate, during use, after alignment, the welded object may experience slight displacement due to minor external vibrations or other interferences. The electric push rod in the fixing component pushes the fixing block and the fixing plate to firmly fix the welded object to the upper surface of the base plate, ensuring that it remains in the correct position during the welding process, which greatly improves the welding accuracy.

[0011] By setting up an alignment component, which includes a central shaft, a mounting plate, a second electric push rod, and a push block, the central shaft serves as the alignment reference, providing a clear reference point for the alignment of the two welded objects. The second electric push rod on the inner surface of the mounting plate pushes the push block, which can precisely adjust the position of the mold so that it is aligned around the central shaft, ensuring that the two molds can achieve highly accurate alignment in all directions.

The base assembly includes: a base body 100, a first base plate 110, and a second base plate 150. The first base plate 110 is mounted on the upper surface of the base body 100, and two second base plates 150 are mounted on the upper surface of the first base plate 110. The fixing assembly 200 includes: a fixing seat 210, an electric push rod 220, a hinge, a fixing block 240, and a fixing plate 250. The electric push rod 220 is mounted on the outer surface of the fixing seat 210. 20. The telescopic rod 230 of the electric push rod 220 passes through the fixed base 210. The inner end of the telescopic rod 230 is fitted with a fixed block 240 via a hinge. The lower surface of the fixed block 240 is fitted with a fixed plate 250 via a spring post. The alignment assembly includes: a central shaft, a mounting plate 120, an electric push rod 130, and a push block 140. The upper surface of the base plate 110 is fitted with the mounting plate 120. The inner surface of the mounting plate 120 is fitted with an electric push rod. The telescopic end of the electric push rod 130 is fitted with a push plate. The central shaft is fitted above the two base plates 150.

[0021] Please see Figures 1 to 3 As the first embodiment of this utility model: a base plate 110 is installed at the center of the upper surface of the base body 100, and two base plates 150 are symmetrically installed on the upper surface of the base plate 110. A gap is provided between the two base plates 150, and the central axis of the gap is collinear with the central axis of the base plate 110. A fixing seat 210 is symmetrically installed on the left edge and the right edge of the upper surface of the base plate 110.

[0022] An electric push rod 220 is installed on the outer surface of the fixed base 210. A telescopic rod 230 is movably provided on the inner surface of the fixed base 210 through the electric push rod 220. A hinge is hinged to the end of the telescopic rod 230 away from the fixed base 210. A fixing block 240 is hinged to the lower surface of the hinge. A spring column is movably provided on the lower surface of the fixing block 240.

[0023] A fixing plate 250 is installed at the end of the spring column away from the fixing block 240. The lower surface of the fixing plate 250 abuts against the upper surface of the base plate 150 via an electric push rod 220. A mounting plate 120 is symmetrically installed on the left and right edges of the upper surface of the base plate 110. An electric push rod 130 is installed at the center of the inner surface of the mounting plate 120.

[0024] Electric push rod 210 passes through fixed base 210. A push block 140 is installed at the end of electric push rod 210 away from mounting plate 120. The lower surface of push block 140 abuts against the upper surface of base plate 2150.

[0025] In use, the user first places two different welding components on the upper surfaces of the two base plates 150 respectively. After the welding components are placed, the fixing plate 250 inside the fixing assembly 200 moves away from the upper surface of the base plate 150 via the electric push rod 220, the telescopic rod 230, the hinge, and the fixing block 240. At this time, the user can activate the alignment assembly to align the two welding components on the upper surface of the base plate 150 and then perform subsequent welding. After the two welding components are aligned, the user can activate the electric push rod 220 on the outer surface of the fixing seat 210, causing the telescopic rod 230 of the electric push rod 220 to extend. The extension of the fixing block 240 causes the hinge to move, which in turn moves the fixing plate 250 on the lower surface of the fixing block 240 to abut against the upper surface of the workpiece. This fixes the workpiece in place, facilitating subsequent welding operations. After alignment, the workpiece may experience slight displacement due to minor external vibrations or other disturbances. The electric push rod 220 in the fixing assembly 200 pushes the fixing block 240 and the fixing plate 250 to firmly fix the workpiece to the upper surface of the base plate 150, ensuring it remains in the correct position during welding and greatly improving welding accuracy.

[0026] Please see Figures 1 to 3 As a second embodiment of this utility model: the central shaft component includes: electric push rod 300 and center block 310. The center block 310 is installed above the two base plates 150 via the electric push rod 300. The central axis of the center block 310 is collinear with the central axis of the two base plates 150.

[0027] During use, when the workpiece is placed on the upper surface of base plate 2 150, the user can activate electric push rod 300 to move the center block 310 downwards, positioning it between the two base plates 2 150 and along their central axis. After adjusting the center block 310, the user can activate electric push rod 2 130 on the inner surface of mounting plate 120, causing push rod 2 130 to move push block 140 on the upper surface of base plate 2 150. This, in turn, moves the workpiece on the upper surface of base plate 2 150. Once both workpieces have moved towards and abutted against center block 310 via electric push rod 2 130, the user can activate electric push rod 300 to move center block 310 upwards, removing it from the mounting plate. At this time, the user simultaneously starts the electric push rod 130, causing the push block 140 to drive the two welded objects to abut, thereby completing the centering operation. Since the central shaft serves as the alignment reference during use, it provides a clear reference point for the centering of the two welded objects. The electric push rod 130 on the inner surface of the mounting plate 120 pushes the push block 140, which can precisely adjust the position of the mold so that it is aligned around the central shaft, ensuring that the two molds can achieve highly accurate alignment in all directions.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
