Description

Technical Field

[0001] The invention relates to the technical field of brazing tool welding, and in particular to a welding device for brazing tool production. Background Art

[0002] The drill rod is a tool that connects the drill bit and the rock drill in the mine tunnel engineering. The drill rods generally used in mine tunnel engineering are hexagonal hollow steel and hollow round steel. The inscribed circle diameter of the hexagonal hollow steel is 22mm and 25mm, and the outer diameter of the hollow round steel is 32mm and 38mm. There are finished steel drills and forged steel drills. The finished steel drill is forged to a certain length and then directly installed with the drill head to drill holes. The forged steel drill is cut according to the needs of the hollow hexagonal steel, and then the drill tail and drill head are forged with a forging drill machine, and then the drill head is installed to drill holes. During the production process of the drill rod, it needs to be welded by a welding device.

[0003] A Chinese patent document with authorization announcement number CN116652366B discloses a threaded drill rod friction welding production device and method. The threaded drill rod friction welding production device and method can adjust the contact distance between the two first clamping plates and the threaded drill rod by setting two cylinders and two cranks, so that the anti-slip head contacts the side of the threaded drill rod, thereby adapting to the welding requirements of threaded drill rods of different sizes and lengths.

[0004] However, the structural design of the above-mentioned related technology: although it can adapt to threaded drill rods of different sizes and lengths, after the drill rod is welded, the drill rod must be trimmed first. During the trimming process, some uncut chips will still be trapped on the drill rod. Therefore, when removing the drill rod, it is necessary to first remove the uncut chips from the drill rod, then take out the welded drill rod, and then manually put the unwelded drill rod into the clamping plate for clamping, which makes the pick-up and placement speed of the drill rod slow, inconvenient for continuous pick-up and placement, and thus affects the welding efficiency of the drill rod.

[0005] Therefore, a welding device for producing a brazing tool is proposed to solve the above-mentioned problems. Summary of the invention

The mounting frame 31 is slidably connected to one side of the top of the base 11, and the mounting frame 31 has a feed port and a discharge port. There are multiple clamping assemblies 32, and multiple clamping assemblies 32 are installed on the inner bottom wall of the mounting frame 31 at equal intervals along the length direction of the mounting frame 31 to clamp a long drill rod. In the present embodiment, the clamping assembly 32 belongs to the prior art, and the specific structure and working principle of the clamping assembly 32 are not described here. The extrusion assembly 38 is installed at the feed port of the mounting frame 31. When the extrusion mechanism 1 50 and the extrusion mechanism 2 60 approach the extrusion assembly 38, the uncut debris on the drill rod can be compressed to facilitate the subsequent removal of the debris.

Two sliders 34 are installed at the bottom of the mounting frame 31, and both sliders 34 are slidably connected in the slide groove 12 and are threadedly connected to the ball screw 35.

[0038] The second motor 36 can drive the mounting frame 31 on the slide block 34 to move through the ball screw 35, so as to drive the longer drill rod to approach the shorter drill rod.

[0039] like Figure 4As shown, a guide wheel 33 is rotatably connected to the clamping assembly 32 near the discharge port of the installation frame 31, and a support wheel 37 is rotatably connected inside the installation frame 31. The support wheel 37 is arranged near the feed port of the installation frame 31. Through the guide wheel 33 and the support wheel 37, the drill rod can be supported when the drill rod after welding is pushed to move.

[0040] like Figure 4 and Figure 5 As shown, the extrusion assembly 38 includes a fixed plate 381 arranged on one side of the installation frame 31, a through hole 382 for the drill rod to pass through is opened in the middle of one side of the fixed plate 381, the center of the through hole 382 and the center of the hole on the clamping member 22 are located on the same straight line, and a through slot 383 is opened on both sides of the fixed plate 381 near the through hole 382. Both sides of the inner bottom wall of the through slot 383 are installed with a limiter 384, and in this embodiment, the limiter 384 is a fan-shaped block. Two guide rods 385 are installed on the top of the other side of the fixed plate 381, and the outer side of the guide rod 385 is sleeved with a spring 386, and one end of the guide rod 385 is installed with a limiter plate 387. Both sides of the inner top wall of the installation frame 31 are installed with an installation box 39, and the limiter plate 387 is slidably connected in the installation box 39, one end of the spring 386 is installed on one side of the limiter plate 387, and the other end of the spring 386 is installed on one side of the inner wall of the installation box 39.

[0041] By pulling the fixing plate 381, the compressed debris can be pushed to move along the length direction of the drill rod, so as to push the debris off the drill rod, thereby removing the debris on the drill rod.

[0042] like Figures 1 to 3 and Figure 6 As shown, the conveying mechanism 40 includes a mounting plate 41, a conveying wheel 42 and an extrusion wheel 43. There are two mounting plates 41, both of which are mounted on one side of the top of the base 11. The mounting plate 41 is L-shaped, and one end of the mounting plate 41 is mounted on one side of the mounting seat 21. There are multiple conveying wheels 42, and multiple conveying wheels 42 are arranged at equal intervals along the length direction of the mounting plate 41, and the conveying wheels 42 are rotatably connected between the two mounting plates 41. In this embodiment, the multiple conveying wheels 42 are connected by belt and pulley transmission, and in other embodiments, the multiple conveying wheels 42 are connected by chain and sprocket transmission. There are multiple extrusion wheels 43, and the transmission mode of the multiple extrusion wheels 43 is the same as the transmission mode of the multiple conveying wheels 42. In this embodiment, the number of extrusion wheels 43 is two, and in other embodiments, the number of extrusion wheels 43 can be three, four or more, and the extrusion wheels 43 are arranged near the mounting seat 21 and located above the conveying wheels 42, and the extrusion wheels 43 are rotatably connected between the two mounting plates 41.

[0043] like Figure 3 and Figure 6As shown, a gear 1 44 is installed on the outer side of one end of the conveying wheel 42 near the mounting seat 21, and a gear 2 45 is meshed and connected to the top of the gear 1 44, and the gear 2 45 is installed on the outer side of one end of one of the extrusion wheels 43. Through the arrangement of the gear 1 44 and the gear 2 45, the rotation direction of the conveying wheel 42 can be opposite to the rotation direction of the extrusion wheel 43. A motor 3 46 is installed on one side of the mounting plate 41, and the driving shaft of the motor 3 46 is fixed to one end of one of the conveying wheels 42.

[0044] The motor 3 46 can drive multiple conveying wheels 42 to rotate synchronously, so as to drive two drill rods to be welded to approach the mounting seat 21. When the drill rod moves to below the extrusion wheel 43, the clamping member 22 releases the clamping of the welded drill rod, and then the unwelded drill rod pushes the welded drill rod to move through the combined action of the conveying wheel 42 and the extrusion wheel 43, so that the welded drill rod is separated from the clamping member 22 and completely moved into the mounting frame 31. As the unwelded drill rod continues to move, the welded drill rod can be pushed out of the mounting frame 31 to achieve the effect of automatic unloading.

[0045] As the conveying wheel 42 and the extruding wheel 43 continue to rotate, the longer drill rod is pushed into the installation frame 31 by the shorter drill rod, and at the same time the shorter drill rod enters the clamping member 22. At this time, the longer drill rod is clamped by the clamping assembly 32, and the shorter drill rod is clamped by the clamping member 22, so as to achieve the effect of automatic feeding.

[0046] like Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the extrusion mechanism 1 50 includes a support plate 51, a slide plate 52 and an extrusion plate 1 54. There are two support plates 51, which are respectively installed on both sides of the base 11. The slide plate 52 is slidably connected to the top of the two support plates 51. The extrusion plate 1 54 is located at the bottom of the slide plate 52. A groove 1 55 is provided at the bottom of the extrusion plate 1 54. The groove 1 55 is in an arc shape. Two groups of plug blocks 56 are installed on both sides of the bottom of the extrusion plate 1 54. The groove 1 55 is located between the two groups of plug blocks 56. Two locking components 57 are installed on the side of the extrusion plate 1 54 facing the fixed plate 381. The two locking components 57 can be inserted into the through slot 383 of the fixed plate 381 to pull the fixed plate 381 to move.

[0047] like Figure 7 As shown, a telescopic member 53 is installed on the top of the slide plate 52. In this embodiment, the telescopic member 53 is a cylinder. In other embodiments, the telescopic member 53 is a hydraulic cylinder or an electric telescopic rod. The telescopic member 53 can drive the extrusion plate 54 to move downward so that the inner wall of the groove 55 contacts the welded drill rod.

[0048] like Figure 7 and Figure 8 As shown, the locking assembly 57 includes a mounting block 571 and two locking blocks 574. The mounting block 571 is mounted on the extrusion plate 54. Receiving grooves 572 for accommodating the locking blocks 574 are provided on both sides of the mounting block 571.

The two locking blocks 574 are respectively mounted on one end of the two elastic sheets 573, and one end of the locking block 574 has an arc surface.

[0049] When the mounting block 571 is inserted into the through slot 383 of the fixing plate 381, the limiting member 384 can squeeze the locking block 574, causing the locking block 574 to move into the accommodating slot 572 and compress the elastic sheet 573. When the locking block 574 passes over the limiting member 384, the locking block 574 is pushed out by the elastic sheet 573 and contacts the limiting member 384.

[0050] like Figure 1 , Figure 2 and Fig. 9 As shown, the extrusion mechanism 2 60 includes a driving assembly 61 located in the mounting groove 13 and a sliding assembly 64 arranged on the driving assembly 61. A motor 4 63 is provided on one side of the driving assembly 61. The motor 4 63 is slidably connected to one side of the base 11. The base 11 is provided with a groove for the sliding of the driving shaft of the power supply motor 4 63.

[0051] like Figure 2 and Fig. 9 As shown, the driving assembly 61 includes a mounting frame 611, a connecting rod 612, a reciprocating screw 613 and a connecting plate 614. The mounting frame 611 is slidably connected in the mounting groove 13, and support blocks are installed at the top four corners of the mounting frame 611. There are two connecting rods 612, one of which is fixedly installed between the two support blocks of the mounting frame 611, and the other connecting rod 612 is rotatably connected between the other two support blocks of the mounting frame 611. One end of the reciprocating screw 613 is installed on the rotatably arranged connecting rod 612, and the driving shaft of the motor 4 63 is connected to the rotatably arranged connecting rod 612. There are two connecting plates 614, and the two connecting plates 614 are respectively installed on both sides of the mounting frame 611, and the connecting plates 614 pass through the slide groove 2 15 and extend to the outside of the base 11.

[0052] A telescopic member 2 62 is installed on the top of the connecting plate 614, and the telescopic member 2 62 is installed on the base 11. The telescopic member 1 53 has the same structure as the telescopic member 2 62. The telescopic member 2 62 can drive the mounting frame 611 to move up and down in the mounting groove 13 to drive the sliding assembly 64 to move up and down.

[0053] Continue to refer Figure 2 and Fig. 9As shown, the sliding assembly 64 includes a movable plate 641, two support rods 642 and two connecting blocks 643. The movable plate 641 is located in the receiving groove 14, the two support rods 642 are respectively installed on both sides of the bottom of the movable plate 641, and the two connecting blocks 643 are respectively installed at the bottom ends of the two support rods 642. A groove for the support rods 642 to slide is provided on the top of the base 11, one of the connecting blocks 643 is threadedly connected to the reciprocating screw 613, and the other connecting block 643 is slidably connected to the fixed connecting rod 612.

[0054] A second groove 644 is formed on the top of the movable plate 641 . The first groove 55 and the second groove 644 have the same shape. A slot 645 for inserting the insert block 56 is formed on the top of the movable plate 641 .

[0055] Working principle: when the drill rod welding is completed, the clamping assembly 32 is released, and then the motor 1 23 drives the welded drill rod to rotate through the clamping member 22 and trims the drill rod through the cutting mechanism. After the trimming is completed, the two drill rods to be welded are transported to the conveying wheel 42 through the external conveyor, and then the motor 3 46 drives multiple conveying wheels 42 to rotate synchronously. At this time, the two drill rods to be welded approach the mounting seat 21. When the drill rod moves below the extrusion wheel 43, the clamping member 22 releases the clamping of the welded drill rod, and then through the joint action of the conveying wheel 42 and the extrusion wheel 43, the unwelded drill rod pushes the welded drill rod to move, so that the welded drill rod is separated from the clamping member 22 and completely moved into the mounting frame 31. In the process of pushing the welded drill rod into the mounting frame 31, the iron filings on the welded drill rod are transferred to the unwelded drill rod, and at the same time, the iron filings are blocked from entering the mounting frame 31 by the fixing plate 381. As the unwelded drill rod continues to move, the welded drill rod can be pushed out of the mounting frame 31.

[0056] As the conveying wheel 42 and the extruding wheel 43 continue to rotate, the longer drill rod is pushed into the installation frame 31 by the shorter drill rod, and at the same time the shorter drill rod enters the clamping member 22. At this time, the longer drill rod is clamped by the clamping assembly 32, and the shorter drill rod is clamped by the clamping member 22.

[0057] Then the motor 2 36 drives the mounting frame 31 on the slider 34 to move through the ball screw 35. When the longer drill rod is separated from the shorter drill rod, the extrusion plate 1 54 is driven downward by the telescopic member 1 53 so that the inner wall of the groove 1 55 contacts the welded drill rod. At the same time, the telescopic member 2 62 drives the movable plate 641 to move out of the storage groove 14 through the mounting frame 611. At the same time, the insert block 56 on the extrusion plate 1 54 is inserted into the slot 645 of the movable plate 641, so that the extrusion plate 1 54 and the movable plate 641 are jointly sleeved on the outside of the longer drill rod.

[0058] At this time, the motor 4 63 is started, and the motor 4 63 drives the movable plate 641 to approach the fixed plate 381 through the reciprocating screw 613 on the connecting rod 612. At the same time, the extrusion plate 1 54 moves synchronously with the movable plate 641. In the process of approaching the fixed plate 381, the extrusion plate 1 54 and the movable plate 641 squeeze the debris to compact the debris and prevent the iron filings from being transferred to the shorter drill rod. When the extrusion plate 1 54 moves to the extreme position, the mounting block 571 on the extrusion plate 1 54 is fully inserted. In the through groove 383 of the fixed plate 381, the extrusion plate 1 54 and the movable plate 641 move in opposite directions through the reverse rotation of the reciprocating screw 613. At this time, the extrusion plate 1 54 pulls the fixed plate 381 to move synchronously through the locking block 574 on the mounting block 571, so that the compacted debris moves toward the end of the drill rod. When the fixed plate 381 moves to the end of the drill rod, the compacted debris is pushed out of the drill rod. At this time, the telescopic member 2 62 drives the movable plate 641 to reset, and the telescopic member 1 53 drives the extrusion plate 1 54 to reset.

[0059] During the resetting process of the extrusion plate 1 54, the locking block 574 gradually moves upward and disengages from the limiting member 384 on the fixing plate 381, so that the fixing plate 381 is reset, and at this time, the second round of welding of the drill rod begins.

[0060] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
