Description

Technical Field

[0001] This utility model relates to the field of ship modification technology, specifically a welding fixture for an outer shell end cap. Background Technology

[0002] In the process of ship production and modification, the protective shell of cables is an important component to ensure the safe operation of cables. The welding quality of the end caps on both sides directly affects the sealing performance, protective performance and overall structural strength of the protective shell. In the existing technology, the clamping fixtures for welding the end caps of cable protective shells generally adopt relatively complex mechanical structures to fix the shell and end caps. These complex structures not only increase the manufacturing cost and maintenance difficulty of the fixtures, but also lead to cumbersome operation procedures and reduce production efficiency.

[0003] More importantly, traditional clamping fixtures struggle to guarantee stability when positioning the outer casing and end caps. During welding, this instability can lead to relative displacement between the end cap and the outer casing, causing misalignment and incomplete welds, severely impacting welding quality and reducing the protective function of the cable protective casing, thus posing a safety hazard to ship operations. Therefore, there is an urgent need to design a simple and stable clamping fixture to improve the welding quality and production efficiency of cable protective casing end caps. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution: a welding fixture for an outer shell end cap, comprising an operating table, wherein two sets of positioning fixtures are installed on the operating table, and the positioning fixtures include two sets of support components, a push-cap component opposite to the corresponding support component, and a side-push cylinder opposite to the side of the corresponding support component.

[0005] The support assembly includes a guide block, on which a propulsion cylinder with its output end facing outward is mounted, and a support block slidably connected to the output end of the propulsion cylinder. The sides and top of the support block are both sloped, making the top of the support block V-shaped.

[0006] The side of the support block is also provided with a clamping end;

[0007] The push-cover assembly includes a counter seat, on which an ejector cylinder is mounted. A T-block is fixed to the piston rod of the ejector cylinder, and a slide plate is fixed to the head end of the T-block. A boss is formed on the surface of the slide plate.

[0008] Furthermore, a V-shaped block is locked and fixed on the slope of the side of the support block, and a waist hole is provided at the screw locking point of the V-shaped block.

[0009] Furthermore, the clamping end includes an auxiliary block and a recessed block fixed on the same side of the support block and distributed vertically. Two sets of bolts are locked inside the recessed block, and a push block is inserted between the outer sides of the bolts. A spring is also sleeved on the outer side of the bolts.

[0010] Furthermore, the operating table is also equipped with the same number of side pressure components as the support components. The side pressure components include a base, on which a direct-push cylinder and a connecting rod are mounted. A U-shaped plate is hinged between the piston rod of the direct-push cylinder and the connecting rod, and a pressure head is mounted on one end of the U-shaped plate.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] The welding fixture for the end cap of the outer shell uses a support block and a V-block to position the outer shell. The waist hole design allows for adjustment of the V-block position, accommodating stable support and limiting of different specifications of outer shells. The spring and push block at the clamping end form an elastic clamping structure, which can clamp and fix the end cap to prevent vertical movement. The ejector cylinder drives the T-block and the slide plate to move horizontally. The slide plate is adapted to the end cap to achieve axial positioning of the end cap and the outer shell, ensuring the alignment accuracy of the weld. The side pressure component drives the connecting rod and U-shaped plate through the direct push cylinder, which drives the pressure head to press the outer shell. The side push cylinder simultaneously applies lateral thrust to form multi-dimensional clamping, eliminating the risk of workpiece displacement during welding and reducing problems such as weld misalignment and incomplete welding.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-7 In this embodiment, a welding fixture for an outer shell end cap includes an operating table 1. Two sets of positioning fixtures are installed on the operating table 1. Each set of positioning fixtures includes two sets of support components 2, a push-cover component 4, a side-push cylinder 5, and a side-press component 3. The two sets of support components 2 on the same axis are distributed in opposite directions, and the push-cover component 4 is opposite to the corresponding support component 2. The side-push cylinder 5 is located on the side of the support component 2, and the top end of the side-push cylinder 5 is a side-push plate.

[0023] In the above structure, the outer shell is placed between two sets of support components. Then, the side-push cylinder and the side-pressure component operate. The side-pressure component works with the support components to press the top of the outer shell tightly. The side-push cylinder drives the side-push plate to work with the support components to clamp and fix the side of the outer shell. The end cap is then fixed in the support components and fits against both ends of the outer shell. The end cap is then pushed out by the push-cap component to clamp the end cap, improving the firmness of the fit. Therefore, during the welding process, a multi-dimensional three-dimensional clamping is formed, eliminating the risk of workpiece displacement during welding and reducing problems such as weld misalignment and incomplete welding.

[0024] like Figure 2-3 The support assembly 2 includes a guide block 21 fixed on the operating table 1. A propulsion cylinder 22 is installed on the inner side of the guide block 21, and a support block 23 is slidably connected and fixed to the piston rod of the propulsion cylinder 22. The front of the support block 23 is inclined, and the top is also inclined, so that the top of the support block 23 is V-shaped and fits the inner side of the shell, which can better support the shell. A V-shaped block 24 is fixed to the inclined surface of the side of the support block 23 by screws. The screw of the V-shaped block 24 has a waist hole, so that the position of the V-shaped block 24 can be adjusted up and down as needed. When the shell is placed on the support block, the side will be supported and limited by the V-shaped block. At the same time, the propulsion cylinder can also be finely adjusted by pushing the support block.

[0025] In this assembly, an auxiliary block 29 and a recessed block 25 are fixed to the side of the support block 23 opposite to the push cover assembly 4. Two sets of bolts 26 are locked and fixed inside the recessed block 25. A push block 28 opposite to the auxiliary block 29 is connected through the outer side of the bolts 26. A spring 27 is sleeved on the outer side of the bolts 26. By inserting the protruding edge of the end cover between the push block and the auxiliary block, the spring force pushes the push block to cooperate with the auxiliary block to clamp and position it, so that the end cover is in contact with both ends of the outer shell.

[0026] like Figure 4 The push-cover assembly 4 includes a counter seat 41 fixed on the operating table 1. An ejector cylinder 42, opposite to the end cover, is mounted on the counter seat 41. A T-block 43 is fixed to the piston rod of the ejector cylinder 42, and a sliding plate 44 is fixed to the head end of the T-block 43. A convex surface is formed on the surface of the sliding plate 44. When the end cover is clamped and fixed, the ejector cylinder drives the T-block to eject, and the surface of the sliding plate is in close contact with the end cover surface. The convex surface is located at the bottom of the end cover, forming a support, thereby maximizing the stability of the end cover positioning and preventing displacement during welding.

[0027] like Figure 5 The side-pressure assembly 3 includes a base 31 fixed on the operating table 1. The base 31 is close to the support assembly 2 and on the same side as the side-push cylinder 5. A direct-push cylinder 32 is mounted on the back of the base 31, and a connecting rod 33 is hinged to the front. A U-shaped plate 34 is hinged between the piston rod of the direct-push cylinder 32 and the connecting rod 33. A pressure head 35 is fixed to the head end of the U-shaped plate 34. By operating the direct-push cylinder, the U-shaped plate and the connecting rod are engaged, which drives the pressure head to press the outer shell down and tighten it, improving the stability of the outer shell positioning.

[0028] The working principle of the above embodiments is as follows:

[0029] After the propulsion cylinder pushes the support block to the appropriate position as needed, the outer shell frame is placed between the two support blocks. The V-block acts as a limit for the outer shell. Then, the side-push cylinder pushes out and clamps and fixes the side of the outer shell with the cooperation of the support block. At the same time, the direct-push cylinder runs, and the linkage between the connecting rod and the U-shaped plate drives the pressure head to press the outer shell down and tighten it, improving the firmness of the clamping of the outer shell. The end cap is inserted between the auxiliary block and the push block. The elastic force of the spring pushes the push block to clamp the end cap, so that the end cap fits with the port of the outer shell. Then, the ejection cylinder drives the T-block to push out, and the slide plate presses the end cap tight, improving the stability of the end cap. Therefore, it can avoid the displacement during the welding process, eliminate the risk of workpiece displacement during the welding process, and reduce problems such as weld misalignment and incomplete welding.
