Description

Technical Field

[0001] This invention relates to the field of connector technology, specifically to a tooling for butt welding of flat steel balls and flat steel balls. Background Technology

[0002] In many industrial sectors such as shipbuilding and steel structure construction, the butt joint of bulb flats and flat bars is a common operation. However, traditional methods of butt jointing bulb flats and flat bars have several drawbacks:

[0003] The lack of effective fixing devices means that during the butt welding process, there is usually no specialized tooling to accurately position and stably fix the bulb flats and flat bars. This makes it easy for the bulb flats and flat bars to shift relative to each other before welding, making it difficult to ensure the accuracy of their vertical splicing, thus affecting the quality and stability of the entire structure. Due to the lack of suitable fixing and support structures, workers often need to hold the flat bars by hand during welding to prevent them from shaking or shifting. This not only increases the labor intensity of workers, but also makes it difficult to ensure the consistency and reliability of welding quality due to the instability of the hands, and may also lead to welding defects such as uneven welds and incomplete welds due to operational inconvenience. Traditional methods require multiple adjustments and fixations of the bulb flats and flat bars during butt welding, resulting in cumbersome procedures, consuming a lot of time and manpower, and leading to low overall splicing efficiency, which cannot meet the needs of large-scale industrial production for efficient operation. Summary of the Invention

[0004] The purpose of this invention is to provide a tooling for butt welding of bulb flat steel and flat steel to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tooling for butt welding of bulb flat steel and flat steel, comprising a connecting strip, the connecting strip being installed between the bulb flat steel and the flat steel, the connecting strip being sleeved on the protruding end of the bulb flat steel, a support plate being fixed to the surface of the connecting strip, a limit strip being fixed to the surface of the connecting strip, the flat steel being inserted between the limit strip and the support plate, an opening being provided on the surface of the support plate, a clamping block being inserted into the top surface of the opening, an insert block being inserted into the inside of the opening, the insert block pushing the clamping block to clamp the flat steel, and a long-shank screw being screwed to the bottom surface of the support plate, the long-shank screw penetrating the support plate and the flat steel and then screwed to the surface of the limit strip.

[0006] Preferably, the surface of the connecting strip is provided with multiple screw holes, which are convex circular holes. The surface of the bulb flat steel is provided with multiple screw grooves, which correspond one-to-one with the screw holes. A connecting screw is screwed into the inside of the screw groove, and one end of the connecting screw passes through the screw hole and is screwed into the screw groove.

[0007] Preferably, the connecting strip, the ball flat steel, and the flat steel are of equal length. Two support plates are provided, and the two support plates are respectively fixed at both ends of the connecting strip. Multiple through holes are opened on the surface of the flat steel and the support plates, and the through holes on the surface of the flat steel and the support plates are penetrated by long-shank screws.

[0008] Preferably, the surface of the connecting strip is provided with a second notch, which is located between the two support plates.

[0009] Preferably, the pallet has a side groove on the side near the flat steel, and an insertion port is formed on the surface of the side groove. The insertion port connects the side groove and the through port. The clamping block passes through the insertion port. A rubber band is fixed between the two parallel side walls of the side groove. One end of the clamping block is fixed to the surface of the rubber band. When the insertion block pushes the clamping block to clamp the flat steel, the clamping block stretches the rubber band to deform, and the rubber band is clamped between the clamping block and the flat steel.

[0010] Preferably, the other end of the clamping block has a slope.

[0011] Preferably, one end of the tray has a notch, and a stop block is slidably connected inside the notch. The stop block is fixed to the surface of the insert block, and a through hole is opened on the surface of the stop block. A screw is inserted into the through hole, and one end of the screw is fixed to the surface of the notch. The length of the screw is greater than the thickness of the stop block, and the length of the screw is equal to the depth of the notch. A nut is screwed onto one end of the screw.

[0012] One side of the wing plate has a gap at one end of the insert block, and the surface of the insert block has a slotted groove located between one side of the wing plate and one end of the insert block.

[0013] Preferably, both ends of the limiting strip are provided with wing plates, the flat steel is located between the two wing plates, and screws are screwed onto the surface of the wing plates. The screws pass through the wing plates and are screwed onto the surface of the limiting strip.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The tooling for butt jointing flat steel and spherical flat steel proposed in this invention uses a combination of clamping blocks, insert blocks, and rubber bands on a pallet. In the initial stage of vertical splicing of flat steel and spherical flat steel, the insert blocks are pushed into the opening to push the clamping blocks, and the clamping blocks stretch the rubber band to deform and tightly clamp the rubber band to the bottom of the flat steel. This achieves pre-limiting during vertical splicing of spherical flat steel and flat steel, further enhancing the stability of the splicing and preventing the flat steel and spherical flat steel from falling off.

[0016] The connecting strip and the bulb flat steel can be easily welded at the two notches, while the flat steel and the connecting strip are welded simultaneously to complete the splicing and welding fixation. Since the bulb flat steel and the flat steel have been precisely positioned and stably fixed by tooling before welding, the workers do not need to hold the flat steel by hand, freeing their hands and allowing them to focus more on the welding work more conveniently. This helps to improve welding quality and efficiency and reduce the occurrence of welding defects. Attached Figure Description

[0030] In order to clearly and completely describe the objectives and technical solutions of the present invention and make the advantages more clearly understood, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0031] Please refer to Figures 1 to 12 , the present invention provides a technical solution: a butt joint tool for bulb flat steel and flat steel, including a connecting strip 1, the connecting strip 1 is installed between the bulb flat steel 2 and the flat steel 3, and a plurality of screw holes 22 are formed on the surface of the connecting strip 1. The screw holes 22 are "convex"-shaped circular holes. A plurality of screw connection grooves 23 are formed on the surface of the bulb flat steel 2. The screw connection grooves 23 and the screw holes 22 correspond to each other one by one. A connecting screw 24 is screwed inside the screw connection groove 23. One end of the connecting screw 24 penetrates through the screw hole 22 and is screwed in the screw connection groove 23. The connecting strip 1 is sleeved on the protruding end of the bulb flat steel 2. A support plate 4 is fixed on the surface of the connecting strip 1, and a limiting strip 5 is fixed on the surface of the connecting strip 1. The flat steel 3 is inserted between the limiting strip 5 and the support plate 4; a second notch 26 is formed on the surface of the connecting strip 1, and the second notch 26 is located between two support plates 4. During use, one end of the connecting strip 1 is pushed along one side of the bulb flat steel 2. When the connecting strip 1 is completely sleeved on one end of the bulb flat steel 2, the connecting screw 24 is passed through the screw hole 22 and screwed in the screw connection groove 23. At this time, the connecting strip 1 and the bulb flat steel 2 are fixed together. Then, one end of the flat steel 3 is inserted between the limiting strip 5 and the support plate 4. The limiting strip 5 is used to fill the gap between the flat steel 3 and the connecting strip 1 to prevent the flat steel 3 from shaking when it abuts against one side of the connecting strip 1. At this time, the bulb flat steel 2 and the flat steel 3 are perpendicular. The connecting strip 1 and the bulb flat steel 2 can be welded at the second notch 26, and the flat steel 3 and the connecting strip 1 can also be welded, completing the welding and fixing after the splicing of the bulb flat steel 2 and the flat steel 3.

[0032] The surface of the pallet 4 has an opening 6, the top surface of which is fitted with a clamping block 8, and the inside of which is fitted with an insert block 10. The insert block 10 pushes the clamping block 8 to clamp the flat steel 3. The bottom surface of the pallet 4 is screwed with a long-shank screw 18, which passes through the pallet 4 and the flat steel 3 and is screwed onto the surface of the limiting strip 5. The connecting strip 1, the ball flat steel 2, and the flat steel 3 are all of equal length. There are two pallets 4, which are fixed to the two ends of the connecting strip 1 respectively. The pallet 4 is close to A side groove 7 is provided on one side of the flat steel 3, and an insertion port 25 is provided on the surface of the side groove 7. The insertion port 25 connects the side groove 7 and the through port 6. The clamping block 8 passes through the insertion port 25. A rubber band 9 is fixed between the two parallel side walls of the side groove 7. One end of the clamping block 8 is fixed to the surface of the rubber band 9. When the insertion block 10 pushes the clamping block 8 to clamp the flat steel 3, the clamping block 8 stretches the rubber band 9 to deform, and the rubber band 9 is clamped between the clamping block 8 and the flat steel 3. The other end of the clamping block 8 is provided with a slope 11. In use, when the flat steel 3 and the bulb flat steel 2 are initially joined vertically, that is, when neither the bulb flat steel 2 nor the flat steel 3 is welded to the connecting strip 1, the insert block 10 is pushed into the through opening 6. The insert block 10 pushes the clamping block 8 along the slope 11. When the clamping block 8 moves along the insertion opening 25, it stretches the rubber band 9 to deform. When the insert block 10 is fully inserted into the through opening 6, the clamping block 8 tightly clamps the rubber band 9 to the bottom of the flat steel 3, achieving the pre-limiting position when the bulb flat steel 2 and the flat steel 3 are joined vertically, preventing the flat steel 3 and the bulb flat steel 2 from falling off. In this way, when welding the connecting strip 1, the bulb flat steel 2, and the flat steel 3 at the notch 26, it is not necessary to hold the flat steel 3 by hand, which frees up the workers' hands to carry out the welding work.

[0033] One end of the support plate 4 has a notch 13, and a stop block 12 is slidably connected inside the notch 13. The stop block 12 is fixed to the surface of the insert block 10. A through hole 14 is opened on the surface of the stop block 12, and a screw 15 is inserted into the through hole 14. One end of the screw 15 is fixed to the surface of the notch 13. The length of the screw 15 is greater than the thickness of the stop block 12, and the length of the screw 15 is equal to the depth of the notch 13. A nut 16 is screwed onto one end of the screw 15. One side of the wing plate 20 has a gap at one end of the insert block 10. A slot 19 is opened on the surface of the insert block 10. The slot 19 is located between one side of the wing plate 20 and one end of the insert block 10. Both ends of the limiting strip 5 have wing plates 20. The flat steel 3 is located between the two wing plates 20. A screw 21 is screwed onto the surface of the wing plate 20. The screw 21 passes through the wing plate 20 and is screwed onto the surface of the limiting strip 5. In use, after the insert 10 is fully inserted into the through-hole 6, the stop 12 slides into the notch 13, and the screw 15 passes through the through hole 14. The nut 16 is screwed onto the end of the screw 15. At this time, the stop 12 is limited in the notch 13, thus preventing the insert 10 from falling out of the through-hole 6. In this way, the insert 10 stably pushes the clamping block 8 to clamp and limit the flat steel 3. The reason for fixing the wing plate 20 to the end of the limiting strip 5 with the screw 21 is to facilitate the removal of the wing plate 20 from the end of the limiting strip 5 after removing the screw 21. The removal time is: when the flat steel 3 is perpendicular to the ball flat steel 2 and is clamped and limited by the clamping block 8, if the wing plate 20 does not affect the normal use of the ball flat steel 2 and the flat steel 3 after assembly, the wing plate 20 may not need to be removed.

[0034] Multiple through holes 17 are provided on the surfaces of the flat steel 3 and the pallet 4. The through holes 17 on the surfaces of the flat steel 3 and the pallet 4 are penetrated by long-shank screws 18. The reason for adding long-shank screws 18 is that after the flat steel 3 is clamped by the clamping block 8, the long-shank screws 18 penetrate the pallet 4 and the flat steel 3 and are screwed onto the surface of the limiting strip 5, thereby fixing the flat steel 3 on the pallet 4 and reducing the splicing firmness of the flat steel 3 and the ball flat steel 2 when they are not welded.

[0035] Method of using the butt joint fixture for bulb flat steel and flat steel: Push one end of the connecting strip 1 along one side of the bulb flat steel 2 so that the connecting strip 1 is completely fitted onto the protruding end of the bulb flat steel 2. Pass the connecting bolt 24 through the bolt hole 22 on the surface of the connecting strip 1 and screw it into the bolt groove 23 on the surface of the bulb flat steel 2 to fix the connecting strip 1 and the bulb flat steel 2 together. Insert one end of the flat steel 3 between the limiting strip 5 and the support plate 4 on the surface of the connecting strip 1. At this time, the limiting strip 5 fills the gap between the flat steel 3 and the connecting strip 1, so that the bulb flat steel 2 and the flat steel 3 are in a vertical state. Flat steel pre-limiting operation: Before the bulb flat steel 2 and the flat steel 3 are welded to the connecting strip 1, push the insert block 10 into the through hole 6 on the surface of the support plate 4. The insert block 10 pushes the clamping block 8 along the slope 11 of the clamping block 8. The clamping block 8 moves along the insertion hole 25 on the surface of the side groove 7, while the rubber band 9 is stretched to deform it. After the insert block 10 is fully inserted into the through-hole 6, the clamping block 8 tightly clamps the rubber band 9 to the bottom of the flat steel 3, achieving pre-limiting when the bulb flat steel 2 and flat steel 3 are vertically spliced, preventing the flat steel 3 and bulb flat steel 2 from falling off. Fixing the insert block: After the insert block 10 is fully inserted into the through-hole 6, the stop block 12 fixed to the surface of the insert block 10 slides into the notch 13 at one end of the support plate 4, so that the screw 15 on the surface of the notch 13 passes through the through hole 14 on the surface of the stop block 12. The nut 16 is screwed onto the end of the screw 15, so that the stop block 12 is limited in the notch 13, preventing the insert block 10 from falling off the through-hole 6, and ensuring that the insert block 10 stably pushes the clamping block 8 to clamp and limit the flat steel 3. A long-shank screw 18 is used to penetrate the through holes 17 on the surfaces of the support plate 4 and the flat steel 3, and then screwed onto the surface of the limiting strip 5 to fix the flat steel 3 onto the support plate 4, further enhancing the splicing strength of the flat steel 3 and the bulb flat steel 2 before welding. At the notch 26 on the surface of the connecting strip 1, the connecting strip 1 and the bulb flat steel 2 are welded together, and the flat steel 3 is simultaneously welded to the connecting strip 1, completing the welding and fixing of the bulb flat steel 2 and the flat steel 3 after splicing. When the flat steel 3 is perpendicular to the bulb flat steel 2 and is clamped and limited by the clamping block 8, if the wing plate 20 affects the normal use of the assembled bulb flat steel 2 and flat steel 3, the screws 21 screwed onto the surface of the wing plate 20 at the end of the limiting strip 5 can be removed, and the wing plate 20 can be removed from the end of the limiting strip 5; if the wing plate 20 does not affect normal use, it can also be left unremoved.

[0036] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
