Abstract

This utility model discloses a corrugated plate welding positioning structure for oxidation chamber assembly, relating to the field of corrugated plate welding technology. It includes a workbench with a welding platform on its upper wall. A corrugated positioning seat for limiting the horizontal position of the corrugated plate body is detachably installed on the upper wall of the welding platform. The welding platform consists of a fixed positioning platform and a sliding driving platform. The driving platform can move along the workbench to adjust the gap of the butt weld.

Description

Technical Field

[0001] This utility model relates to the field of corrugated plate welding technology, specifically a corrugated plate welding positioning structure for assembling an oxidation chamber. Background Technology

[0002] Oxidation chamber shells are mostly constructed by splicing and welding corrugated plates. Before welding, the corrugated plates require precise alignment using positioning fixtures to ensure uniform weld gaps and meet splicing accuracy standards. Existing corrugated plate welding positioning fixtures generally suffer from the following technical defects: The feeding process is prone to scraping and jamming, resulting in high operating resistance. Positioning fixtures often use a positioning method where the boss is embedded in the corrugated groove. When feeding, manual alignment with the groove is required before dropping the workpiece. During the pushing process, the corrugated groove and the positioning boss are prone to scraping and jamming, which not only results in low feeding efficiency but also easily scratches the coating on the surface of the workpiece.

[0003] The rigid impact during loading can easily damage the workpiece. The lateral positioning clamp directly and rigidly pushes the workpiece, which can easily cause impact deformation at the end of the workpiece, especially for thin-walled corrugated plates, and can affect the splicing sealing performance.

[0004] The weld gap is difficult to adjust. Most positioning fixtures are fixed platforms, which cannot flexibly adjust the butt gap between the two corrugated plates, making it difficult to adapt to the gap requirements of different welding processes and plate thicknesses, resulting in poor adaptability. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a corrugated plate welding and positioning structure for assembling an oxidation chamber, which solves the technical problems of existing devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A corrugated plate welding positioning structure for oxidation chamber assembly includes a worktable. A welding platform is mounted on the upper wall of the worktable. A corrugated positioning seat for limiting the horizontal position of the corrugated plate body is detachably mounted on the upper wall of the welding platform. The welding platform consists of a fixed positioning platform and a sliding drive platform. The drive platform can move along the worktable to adjust the gap of the butt weld. Elastic material support belts are fixedly connected to the welding platform on both sides of the corrugated positioning seat. The elastic material support belts can elastically expand and contract along the height direction of the welding platform. In the free state, the top surface of the elastic material support belt is higher than the top surface of the corrugated positioning seat. A positioning baffle is fixedly mounted on the upper wall of the welding platform, and the elastic material support belt is located between the welding platform and the positioning baffle. A lateral positioning component is mounted at the end of the welding platform away from the positioning baffle. A compensation component is mounted on the lateral positioning component for flexibly pushing the workpiece during clamping and avoiding rigid impact. A clamping component is linked to the lateral positioning component. When the lateral positioning component clamps, the clamping component rises to avoid impact. After the lateral positioning component retracts and the compensation block completely disengages from the workpiece, the clamping component presses down to fix the workpiece.

[0007] Preferably, the upper wall of the welding table is provided with a drive groove; the lateral positioning assembly includes a drive screw, a transmission threaded sleeve, a guide rail, a guide connecting plate, and a positioning clamp; the drive screw is rotatably connected to the inside of the welding table, the transmission threaded sleeve is screwed onto the drive screw and is slidably adapted to the drive groove; the guide rail is arranged along the axial direction of the drive screw, the guide connecting plate is slidably and sealingly connected to the guide rail, and the lower wall of the guide connecting plate is fixedly connected to the transmission threaded sleeve; the positioning clamp is fixedly installed on the upper wall of the guide connecting plate, and a guide bevel is provided on the side of the upper end of the positioning clamp near the positioning baffle.

[0008] Preferably, the two ends of the transmission threaded sleeve are sealed to the inner wall of the drive slide groove by a bellows dust cover to isolate welding slag and debris.

[0010] Preferably, the clamping assembly includes a clamping support platform, a clamping block, and a reset spring rod; the clamping block is fixedly installed at the center of the lower wall of the clamping support platform, and the clamping support platform is floatingly connected to the welding table along the height direction of the welding table; the reset spring rod is fixedly installed between the clamping support platform and the welding table, providing downward tension to the clamping support platform; the clamping support platform has mating inclined surfaces on both sides that are adapted to the sliding of the guide angle; when the positioning clamp moves towards the positioning baffle, it pushes the clamping support platform to rise through the guide angle; after the positioning clamp retracts until the compensation block is completely separated from the workpiece, the guide angle gradually retracts, and the clamping support platform descends under the action of the reset spring rod.

[0011] Preferably, the two side walls of the drive table are provided with translation guide grooves, and the upper wall of the worktable is fixedly installed with a limiting and correcting block that is slidably adapted to the translation guide grooves; a drive module is fixedly installed on the worktable, and a push electric actuator is fixedly installed between the drive module and the drive table to push the drive table to move towards the positioning table to adjust the weld gap.

[0013] This utility model provides a corrugated plate welding and positioning structure for assembling an oxidation chamber, which has the following advantages: In this invention, the elastic support belt is higher than the corrugated positioning seat in its free state. When feeding, the workpiece is suspended on the support belt and pushed. There is no contact or scraping between the corrugated groove and the positioning boss. The feeding resistance is small and the efficiency is high, and it can avoid scratching the surface of the workpiece. When the workpiece is pressed, the support belt sinks down with it, without affecting the fitting and positioning of the corrugated groove and the positioning seat.

[0014] The positioning clamp of this utility model has a built-in elastic compensation block. When clamping, the compensation block first flexibly pushes the workpiece against the positioning baffle, and then retracts to complete the rigid clamping, thus avoiding the clamping block directly and rigidly impacting the end of the workpiece.

[0015] The welding station of this utility model adopts a split structure of positioning station and driving station. The driving station is driven to move by electric push rod, which can flexibly adjust the gap of the butt weld of two corrugated plates, adapting to the processing requirements of different welding processes and plate thicknesses, and has stronger adaptability.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figure 1-4As shown, this utility model discloses a corrugated plate welding positioning structure for assembling an oxidation chamber, including a horizontally arranged workbench 1. A welding platform is provided on the upper wall of the workbench 1, and a corrugated positioning seat 2 is detachably installed on the upper wall of the welding platform. The top surface of the corrugated positioning seat 2 is provided with a positioning protrusion that matches the groove of the corrugated plate, used to limit the horizontal position of the corrugated plate body. The corrugated positioning seat 2 is detachably installed by bolts, and different protrusion specifications can be replaced to adapt to corrugated plate bodies with different wave pitches and wave heights, making replacement convenient.

[0020] The welding table consists of a positioning table 3 fixedly mounted on the left side of the workbench 1 and a drive table 4 slidably mounted on the right side of the workbench 1. The drive table 4 can move left and right along the workbench 1 to adjust the gap of the butt weld between two corrugated plates, adapting to different welding process requirements. The front and rear side walls of the drive table 4 are provided with translation guide grooves 24. Limiting and correcting blocks 25 are fixedly installed at corresponding positions on the upper wall of the workbench 1. The limiting and correcting blocks 25 slide and adapt to the translation guide grooves 24 (a sliding seal can be achieved through a bellows sleeve), ensuring the straightness of the drive table 4's translation and preventing misalignment. A drive module is fixedly mounted on the right end of the workbench 1. A push rod 26 is fixedly installed between the drive module and the right side wall of the drive table 4. Pushing the push rod 26 to extend or retract will drive the drive table 4 to move left and right, precisely adjusting the weld gap.

[0021] Both the front and rear sides of the corrugated positioning seat 2 are provided with elastic material support belts 5. The bottom of the elastic material support belts 5 is fixedly connected to the welding table and can elastically extend and retract along the height direction of the welding table. In the free state, the top surface of the elastic material support belts 5 is higher than the top surface of the corrugated positioning seat 2, so that the corrugated plate body is suspended above the positioning protrusion when feeding, and there is no scraping interference during the pushing process. When the workpiece is pressed and sinks, the elastic material support belts 5 can retract accordingly without affecting the positioning and fitting.

[0022] A vertically arranged positioning baffle 6 is fixedly installed on the upper left wall of the welding table. An elastic material support belt 5 is located between the welding table and the positioning baffle 6. When the workpiece is pushed to the left, it finally comes into contact with the positioning baffle 6, completing the lateral reference positioning. A lateral positioning component is provided at the right end of the welding table, which is used to push the workpiece from the right side to the left to fit tightly against the positioning baffle 6.

[0023] The upper wall of the welding station has a drive groove 7 along the left-right direction. The lateral positioning assembly includes a drive screw 8, a transmission threaded sleeve 9, a guide rail 10, a guide connecting plate 11, and a positioning clamp 12. The drive screw 8 is rotatably connected to the cavity inside the welding station. The transmission threaded sleeve 9 is screwed onto the drive screw 8, and its upper part is slidably adapted to the drive groove 7. The guide rail 10 is fixedly installed at the opening of the drive groove 7 along the axial direction of the drive screw 8. The guide connecting plate 11 is slidably and sealingly connected to the guide rail 10, and the lower wall of the guide connecting plate 11 is fixedly connected to the transmission threaded sleeve 9. The positioning clamp 12 is fixedly installed on the upper wall of the guide connecting plate 11 and moves left and right together with the transmission threaded sleeve 9. A guide bevel 13 is provided on the upper left side of the positioning clamp 12 for cooperating with the clamping assembly to achieve linkage transmission.

[0024] The left and right ends of the transmission threaded sleeve 9 are sealed to the inner wall of the drive slide groove 7 by the bellows dust cover 14, forming a full-stroke seal for the transmission pair of the drive screw 8 and the transmission threaded sleeve 9, effectively isolating welding slag and metal chips, and avoiding transmission jamming and wear.

[0025] A receiving groove 15 is formed at the center of the left side wall of the positioning clamping block 12. Auxiliary sliding grooves 16 are formed on both the top and bottom walls of the receiving groove 15. A compensation assembly is disposed within the receiving groove 15, including a compensation abutment 17 and an elastic telescopic rod 18. Limiting sliders 19 are fixedly installed on both the upper and lower walls of the compensation abutment 17. The limiting sliders 19 slide and adapt to the auxiliary sliding grooves 16, limiting the extension and retraction stroke of the compensation abutment 17. The elastic telescopic rod 18 is fixedly installed between the compensation abutment 17 and the bottom of the receiving groove 15, always providing an outward elastic force for the compensation abutment 17. During clamping, the compensation abutment contacts the workpiece first, flexibly pushing the workpiece against the baffle to avoid rigid impact.

[0026] The clamping assembly is linked to the lateral positioning assembly and includes a clamping bearing platform 20, a clamping block 21, and a reset spring rod 22. The clamping block 21 is fixedly installed at the center of the lower wall of the clamping bearing platform 20, which is floatingly connected to the welding table along the height direction of the welding table. The reset spring rod 22 is fixedly installed between the clamping bearing platform 20 and the welding table, always providing a downward pulling force to the clamping bearing platform 20. A mating inclined surface 23 is provided on the right side of the clamping bearing platform 20, which is slidably adapted to the guide angle 13 of the positioning clamping block 12.

[0027] In practical implementation, any existing high-temperature resistant fiberglass bellows cover can be used to replace the ordinary rubber and plastic dust cover to adapt to high-temperature welding conditions; the elastic material support belt 5 can also be replaced with multiple independently arranged elastic floating rollers in the existing technology to further improve the support stability of the corrugated irregular cross section; a micro elastic top ball structure in the existing technology can be added to the side of the positioning baffle to offset the lateral friction force when loosening the clamp; the clamping block 21 can adopt the spring floating pressure head structure in the existing technology to avoid rigid pressure damage to the workpiece surface. The above conventional structures are all well-known technologies in the field and will not be elaborated here.

[0028] Specifically: In the initial state, the drive screw 8 moves the positioning clamp 12 to the left to the lifting stop, and the guide angle 13 wedges into the lower part of the mating slope 23, lifting the pressing support table 20. The pressing block 21 rises to a clearance position where its bottom surface is higher than the top surface of the workpiece. The elastic support belt 5 returns to its original position under its own elastic force, with its top surface higher than the corrugated positioning seat 2. At this time, the corrugated plate body is placed horizontally on the elastic support belt 5 from the driving direction of the drive table 4, and pushed to the left along the support surface to directly below the pressing block 21, so that the corrugated groove is roughly aligned with the protrusion of the corrugated positioning seat 2. The workpiece is suspended in the air throughout the feeding process, without any scraping or jamming resistance.

[0029] The drive screw 8 is activated, causing the positioning clamping block 12 to continue moving to the left. The compensating block 17 first contacts the right end face of the workpiece, flexibly pushing the workpiece to the left until the left side of the workpiece abuts against the positioning baffle 6. The positioning clamping block 12 continues to move to the left, the elastic telescopic rod 18 is compressed, and the compensating block 17 retracts into the receiving groove 15. The left side wall of the positioning clamping block 12 fully abuts against the workpiece, completing the precise lateral positioning. During this process, the clamping bearing platform 20 remains in a raised state, without interfering with the horizontal movement of the workpiece.

[0030] After positioning is completed, the drive screw 8 reverses, causing the positioning clamp 12 to move backward to the right. The entire process is divided into two stages: First stage of retraction: The positioning clamp 12 moves slightly to the right to complete its empty stroke, the elastic telescopic rod 18 gradually returns to its original position and extends, and the compensating block 17 moves to the right along with the positioning clamp 12, completely disengaging from the workpiece sidewall. The clamping bearing platform 20 and the clamping block 21 descend slightly.

[0031] Second stage of retraction: Positioning clamp 12 continues to move to the right, guide angle 13 gradually exits the mating slope 23, pressing bearing platform 20 continues to descend under the pulling force of reset spring rod 22, pressing pressing block 21 presses down on the top surface of the corrugated plate body, vertically pressing and fixing the workpiece.

[0032] After the workpiece is clamped, the corrugated groove is embedded in the protrusion of the corrugated positioning seat 2 to complete the final positioning, and the elastic support belt 5 sinks synchronously with the workpiece. The slight frictional slippage generated during the workpiece's descent is within the allowable tolerance range for corrugated assembly and welding in the oxidation chamber and does not affect the welding quality.

[0033] After the workpiece is positioned and clamped, the electric push rod 26 can be activated to drive the drive table 4 to move horizontally towards the positioning table 3, precisely adjusting the gap between the butt welds of the two corrugated plates to match the corresponding welding process requirements. After adjustment, welding operations can be carried out.

[0034] After welding is completed, the drive screw 8 drives the positioning clamp 12 to move to the left, and pushes the clamping bearing table 20 to rise again. The clamping block 21 rises and releases the workpiece, which can then be pulled out to the right along the elastic support belt 5 to enter the next processing cycle.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
