Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe production technology, specifically a positioning mechanism for welding corrugated pipes and braided mesh. Background Technology

[0002] In fluid transportation, aerospace, petrochemical, new energy and other fields, the combination structure of corrugated pipe and braided mesh is widely used in various pipeline systems, such as high-pressure oil pipes, coolant delivery pipes, gas delivery pipes and precision components, such as sensor lead wire protective sleeves and hydraulic actuator connecting pipes, because it combines the flexibility of corrugated pipes with the tensile and impact resistance of braided mesh. The core performance of this combination structure depends on the welding quality of corrugated pipe and braided mesh, and the welding positioning accuracy is the key prerequisite for determining the welding quality.

[0003] Chinese Utility Model Patent Publication No. CN210059652U discloses a welding machine for corrugated pipes and braided mesh. The specification of this welding machine states that the welded braided mesh and corrugated pipe are perfectly aligned and their relative positions are fixed. Compared to existing equipment, the position of the braided mesh remains unchanged, which is more conducive to the positioning and fixing of the end rings. The welding length of the braided mesh is fixed, which can shorten the allowance for the braided mesh and reduce waste. For products requiring two layers of braided mesh, a layer of corrugated pipe can be welded after the first layer of braided mesh. However, this welding machine for corrugated pipes and braided mesh lacks a positioning structure, making it inconvenient not only to clamp corrugated pipes of different diameters but also to quickly position the flange and braided mesh, resulting in poor overall practicality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a positioning mechanism for welding corrugated pipes and braided mesh. It can effectively solve the problem in the prior art that the lack of a positioning structure makes it not only inconvenient to clamp corrugated pipes of different diameters, but also inconvenient to quickly position flanges and braided mesh, resulting in poor overall practicality.

[0005] The technical solution adopted by this utility model is: a positioning mechanism for welding corrugated pipes and braided mesh, including a welding table and a welding head. A slide rail is fixedly installed at one end of the welding table near the welding head. A slider is slidably connected at one end of the slide rail away from the welding table. A fixed table is snapped onto one end of the slider away from the slide rail. A counter-clamping assembly is fixedly installed at one end of the fixed table away from the welding table. A clamping assembly is fixedly installed at the output end of the counter-clamping assembly. The opposing clamping assembly includes a horizontal cylinder, and a sleeve is fixedly installed at the output end of the horizontal cylinder. The clamping assembly includes an insert block, and a braided mesh sleeve and a flange sleeve are fixedly installed at the end of the insert block away from the opposing clamping assembly.

[0006] Preferably, a positioning hole is provided at the outer edge of the sliding rail, and a first positioning bolt is threadedly connected to the outer edge of the sliding block, wherein the first positioning bolt penetrates the sliding block and extends into the positioning hole.

[0007] Through the above technical solution, the sliding block slides above the sliding rail via the positioning hole of the sliding rail. After the sliding block slides to a proper position, the first positioning bolt penetrates the sliding block and is inserted into the positioning hole, so that the locking of the sliding block and the sliding rail is realized, so that the opposite clamping assembly and the jacket assembly are driven by the fixing table to be fixed at a preset welding position. Fixing tables of different sizes can be selected according to corrugated pipes of different sizes, which can improve the overall practicability.

[0008] Preferably, a clamping member is fixedly mounted at an end of the sliding block away from the sliding rail, a clamping groove is provided at an end of the fixing table close to the sliding block, and the clamping member is inserted into the clamping groove and forms an interference fit therebetween.

[0009] Through the above technical solution, the interference fit between the clamping member and the clamping groove facilitates the rapid connection between the fixing table and the sliding block, which not only avoids the offset of the fixing table caused by welding vibration, but also facilitates the rapid disassembly and assembly of the fixing table, and facilitates the replacement of fixing tables adapted to different workpieces.

[0010] Preferably, a vertical cylinder is fixedly mounted at an end of the welding table away from the welding head, a through groove is provided at the center of the fixing table, and the vertical cylinder and the through groove are located on the same vertical horizontal line.

[0011] Through the above technical solution, with the design of the vertical cylinder and the fixing table, after welding is completed, the piston rod of the vertical cylinder can jack up or support a workpiece along the through groove, which avoids the uneven welding surface caused by the sagging of the workpiece under its own weight, and facilitates auxiliary positioning of the workpiece.

[0012] Preferably, a positioning frame is fixedly mounted at the outer edge of the horizontal cylinder, the cross-section of the positioning frame is in a n-shaped structure, and a second positioning bolt is threadedly connected to the outer edge of the positioning frame.

[0013] Through the above technical solution, the design of the n-shaped positioning frame can encircle the horizontal cylinder and be fixed on the fixing table through the second positioning bolt, which facilitates the fixing of the horizontal cylinder, disperses the reaction force during operation of the horizontal cylinder, and avoids clamping deviation caused by offset of the horizontal cylinder.

[0014] Preferably, a sliding groove is provided at an end of the fixing table away from the welding table, a sliding bar is fixedly mounted at an end of the inserting sleeve close to the sliding groove, and the sliding bar is in sliding connection with the sliding groove.

[0015] With the above technical solution, when the insert is moved by the horizontal cylinder, the slide bar slides along the slide groove of the fixed table, which facilitates the limiting and guiding of the insert and the clamping assembly, avoids radial shaking during the limiting process, and makes the clamping assembly move along the preset straight line to connect with the corrugated pipe and the braided mesh, avoiding clamping deviation.

[0016] Preferably, the end of the insert sleeve away from the horizontal cylinder has a slot, the slot and the insert block are plugged in, the inner edge of the flange sleeve has a reserved groove, and the inner edge of the braided mesh sleeve is fixedly installed with a limit sleeve.

[0017] The above technical solution enables quick replacement of the jacket assembly by inserting the slot of the insert and the plug block. The reserved slot of the flange ferrule and the limiting sleeve of the braided mesh ferrule are respectively adapted to the bellows flange and the braided mesh, which facilitates quick positioning.

[0018] Compared with the prior art, this utility model provides a positioning mechanism for welding corrugated pipes and braided mesh, which has the following advantages: 1. The positioning mechanism for welding corrugated pipe and braided mesh uses the positioning hole of the slide rail to allow the slider to slide above the slide rail. When it slides to the appropriate position, the positioning bolt passes through the slider and is inserted into the positioning hole to lock the slider and the slide rail. This allows the fixed table to drive the opposing clamping component and the clamping component to be fixed in the preset welding position. Different sizes of fixed tables can be selected according to the size of the corrugated pipe, which can improve the overall practicality. 2. The positioning mechanism for welding the corrugated pipe and the braided mesh, when the insert is moved by the horizontal cylinder, the slide bar slides along the slide groove of the fixed platform, which facilitates the limiting and guiding of the insert and the jacket assembly, and avoids radial shaking during the limiting process. The jacket assembly can be quickly replaced by inserting the insert into the slot and insert block. The reserved groove of the flange sleeve and the limiting sleeve of the braided mesh sleeve are respectively adapted to the corrugated pipe flange and the braided mesh, which facilitates rapid positioning.

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] Example 1: As Figure 1-8 As shown, the present invention provides a positioning mechanism for welding corrugated pipes and braided mesh, including a welding table 1 and a welding head 14. A slide rail 2 is fixedly installed at one end of the welding table 1 near the welding head 14. A slider 4 is slidably connected at the end of the slide rail 2 away from the welding table 1. A fixed table 7 is snapped onto the end of the slider 4 away from the slide rail 2. An opposing clamping assembly 11 is fixedly installed at the end of the fixed table 7 away from the welding table 1. A clamping assembly 12 is fixedly installed at the output end of the opposing clamping assembly 11. The opposing clamping assembly 11 includes a horizontal cylinder 1101, and a sleeve 1104 is fixedly installed at the output end of the horizontal cylinder 1101. The jacket assembly 12 includes a plug 1201, and a braided mesh sleeve 1202 and a flange sleeve 1203 are fixedly installed on the end of the plug 1201 away from the opposing clamping assembly 11.

[0023] Specifically, a positioning hole 3 is provided at the outer edge of the slide rail 2, a first positioning bolt 5 is threadedly connected to the outer edge of the slider 4, and the first positioning bolt 5 penetrates the slider 4 and extends into the positioning hole 3. The advantage is that, through the positioning hole 3 of the slide rail 2, the slider 4 can slide above the slide rail 2; after the slider slides to a proper position, the first positioning bolt 5 penetrates the slider 4 and is inserted into the positioning hole 3, so that locking between the slider 4 and the slide rail 2 is realized, which enables the fixing table 7 to drive the opposite clamping assembly 11 and the jacket assembly 12 to be fixed at a preset welding position. The fixing table 7 with different sizes can be selected according to the size of corrugated pipes with different dimensions, which can improve the overall practicability.

[0024] Specifically, a clamping member 6 is fixedly installed at an end of the slider 4 away from the slide rail 2, a clamping groove 8 is provided at an end of the fixing table 7 close to the slider 4, and the clamping member 6 is inserted into the clamping groove 8 and forms an interference fit therebetween. The advantage is that, through the interference fit between the clamping member 6 and the clamping groove 8, rapid connection between the fixing table 7 and the slider 4 can be realized conveniently, which not only avoids the offset of the fixing table 7 caused by welding vibration, but also facilitates rapid disassembly and assembly of the fixing table 7, and facilitates replacement of the fixing table 7 adapted to different workpieces.

[0025] Specifically, a vertical cylinder 13 is fixedly installed at an end of the welding table 1 away from the welding head 14, a through groove 9 is provided at the center of the fixing table 7, and the vertical cylinder 13 and the through groove 9 are located on the same vertical line. The advantage is that, with the design of the vertical cylinder 13 and the fixing table 7, after welding is completed, the piston rod of the vertical cylinder 13 can jack up or support a workpiece along the through groove 9, which avoids uneven welding surface caused by the sagging of the workpiece under self-weight, and facilitates auxiliary positioning of the workpiece.

[0026] Embodiment 2: as Figure 2-8 shown, it is an improvement to the previous embodiment.

[0027] Specifically, a positioning frame 1102 is fixedly installed on the outer edge of the horizontal cylinder 1101, the cross-section of the positioning frame 1102 is in an "Omega"-shaped structure, and a second positioning bolt 1103 is threadedly connected to the outer edge of the positioning frame 1102. The advantage is that the design of the "Omega"-shaped positioning frame 1102 can surround the horizontal cylinder 1101 and is fixed on the fixing table 7 via the second positioning bolt 1103, which facilitates fixing of the horizontal cylinder 1101, disperses the reaction force of the horizontal cylinder 1101 during operation, and avoids clamping deviation caused by offset of the horizontal cylinder 1101.

[0028] Specifically, a groove 10 is provided at the end of the fixed platform 7 away from the welding platform 1, and a slide bar 1106 is fixedly installed at the end of the insert 1104 near the groove 10. The slide bar 1106 and the groove 10 are slidably connected. The advantage is that when the insert 1104 is moved by the horizontal cylinder 1101, the slide bar 1106 slides along the groove 10 of the fixed platform 7, which facilitates the limiting and guiding of the insert 1104 and the clamping assembly 12, and avoids radial shaking during the limiting process, so that the clamping assembly 12 moves along a preset straight line to connect the corrugated pipe and the braided mesh, and avoids clamping deviation.

[0029] Specifically, the end of the insert 1104 away from the horizontal cylinder 1101 has a slot 1105, and the slot 1105 and the insert block 1201 are plugged in. The flange sleeve 1203 has a reserved groove 1204 on its inner edge, and the braided mesh sleeve 1202 has a fixed limit sleeve 1205 on its inner edge. The advantage is that the clamping assembly 12 can be quickly replaced by plugging the insert 1105 of the insert 1104 into the insert block 1201. The reserved groove 1204 of the flange sleeve 1203 and the limit sleeve 1205 of the braided mesh sleeve 1202 are respectively adapted to the bellows flange and the braided mesh, which facilitates quick positioning.

[0030] Working principle: During use, the slider 4 slides above the slide rail 2 through the positioning hole 3. When it reaches the appropriate position, the positioning bolt 5 passes through the slider 4 and inserts into the positioning hole 3, locking the slider 4 to the slide rail 2. This causes the fixed platform 7 to drive the opposing clamping assembly 11 and the clamping assembly 12 to be fixed in the preset welding position. Different sizes of fixed platforms 7 can be selected according to the size of different corrugated pipes, improving overall practicality. The interference fit between the clip 6 and the slot 8 facilitates quick connection between the fixed platform 7 and the slider 4, avoiding displacement of the fixed platform 7 due to welding vibration and facilitating quick assembly and disassembly of the fixed platform 7. This allows for easy replacement of fixed platforms 7 to suit different workpieces. The design of the vertical cylinder 13 and the fixed platform 7 allows the piston rod of the vertical cylinder 13 to lift or support the workpiece along the through groove 9 after welding, preventing uneven welding surfaces caused by the workpiece sagging under its own weight and facilitating workpiece positioning. The design of the frame 1102 allows it to encircle the horizontal cylinder 1101 and be fixed to the fixed platform 7 via the positioning bolt 1103. This facilitates the fixation of the horizontal cylinder 1101, disperses the reaction force of the horizontal cylinder 1101 during operation, and avoids clamping deviation caused by the displacement of the horizontal cylinder 1101. When the horizontal cylinder 1101 drives the insert 1104 to move, the slide bar 1106 slides along the slide groove 10 of the fixed platform 7, which facilitates the limiting and guiding of the insert 1104 and the clamping assembly 12, preventing radial shaking during the limiting process. This allows the clamping assembly 12 to move along a preset straight line, connecting with the corrugated pipe and the braided mesh, preventing clamping deviation. The clamping assembly 12 can be quickly replaced by inserting the insert 1105 of the insert 1104 into the insert block 1201. The reserved groove 1204 of the flange sleeve 1203 and the limiting sleeve 1205 of the braided mesh sleeve 1202 are respectively adapted to the corrugated pipe flange and the braided mesh, facilitating rapid positioning.
