Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of square tube welding, in particular to an equidistant spot welding device for metal piece processing. BACKGROUND

[0002] When producing metal pipe pieces with a square cross section (such as square ventilation pipes and steel structure square pipes), the plate material is first bent into a square shape using bending and other methods, and then the butt joints are welded to form a complete pipe. Since the length of this type of square pipe is usually more than 5m, multiple spot welding is required at the weld to prevent misalignment of the weld during formal welding and to ensure the qualification rate of the metal piece after welding.

[0003] When spot welding such metal pieces, the existing method usually involves welding angle steel or a cross-shaped support in advance to form a temporary rigid structure, thereby preventing problems such as concave deformation caused by misalignment of the welded part during spot welding and welding. However, after welding the metal piece, the angle steel or support needs to be cut and removed, which results in a waste of time for installing and removing the metal piece during mass production, thereby reducing production efficiency. In addition, when using the above method to spot weld from the outside, oxidation occurs at the spot welding site due to resistance spot welding, which requires the oxidation film on the outside to be polished clean after spot welding. Spot welding also easily causes concave deformation near the weld, which affects the continuity of welding and the surface effect after welding. SUMMARY

DETAILED DESCRIPTION

[0021] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0022] Please refer to Figures 1-11 The metal piece processing equidistance spot welding device provided by the embodiment of the present application comprises a bearing mechanism 1, the bearing mechanism 1 comprises a base 11 and a right-angle frame 12 which is slidingly connected inside the base 11, and a square tube 2 is placed on the right-angle frame 12, and the device further comprises: A rope hook 14 is fixedly connected to the base 11; A support mechanism 3 comprises a shell 31 which is placed on the right-angle frame 12, the front side of the shell 31 faces the square tube 2 and is provided with a wire passing port 32, the symmetrically inclined upper side of the shell 31 is provided with a magnet slot 33 and an electromagnet 34 is slidingly connected inside the magnet slot 33, a circular arc shaft 35 is rotatably installed inside the shell 31, a spot welder 39 is fixedly connected to the top of the shell 31, and the rope connected between the circular arc shaft 35 and the rope hook 14 has no elasticity; The driving mechanism 4 comprises a motor 41 fixedly connected inside the shell 31, the motor 41 is in transmission connection with the circular arc shaft 35, a trigger cam 42 is fixedly sleeved on the rotating shaft of the motor 41, a proximity switch 45 is fixedly connected in the shell 31, the trigger cam 42 triggers the proximity switch 45 after one rotation, the proximity switch 45 is in electrical connection between the electromagnet 34 and the spot welder 39, after the trigger cam 42 moves away from the proximity switch 45, the electromagnet 34 and the spot welder 39 are powered off; The correcting mechanism 5 comprises a correcting wheel 51 hingedly connected on the front side of the shell 31, the correcting wheel 51 is in transmission connection with the motor 41, after one rotation of the correcting wheel 51, the movable part of the square tube 2 is pushed outward to be perpendicular to another movable part.

[0023] In the present application, through the support mechanism 3, after the square tube 2 is placed on the right-angle frame 12, the two ends of the rope are fixedly connected on the rope hook 14 and the circular arc shaft 35 respectively, then the motor 41 is started, at this time, the rotation of the motor 41 drives the circular arc shaft 35 to rotate through transmission, so as to wind the rope on the circular arc shaft 35, at this time, the whole support mechanism 3 is pulled forward to move forward, with the rotation of the motor 41, the trigger cam 42 on the rotating shaft of the motor 41 activates the electromagnet 34 after abutting against the proximity switch 45, so that the electromagnet 34 is moved to the upper side under the influence of magnetic force and is adsorbed on the inner wall of the square tube 2, at the same time, the proximity switch 45 also activates the spot welder 39, so that the spot welder 39 is used for spot welding the gap formed after the square tube 2 is adsorbed, the above-mentioned setting makes the gap be welded, the plate materials at the welded position are adsorbed on the mutually perpendicular inclined surface on the top of the shell 31 by the electromagnet 34, so that the spot welder 39 not only ensures that the welded positions are mutually perpendicular and do not appear misalignment when spot welding, but also forms an integral whole with the support mechanism 3 and the square tube 2 when welding, so as to ensure that the support mechanism 3 does not shake when spot welding and cannot align the gap for welding.

[0024] Secondly, when the support mechanism 3 is about to enter the inside of the square tube 2, if the square tube 2 is inwardly misaligned due to hoisting, bending error or other reasons, the misaligned part of the square tube 2 will directly contact the front side of the support mechanism 3 after it approaches, causing the support mechanism 3 to be blocked by the end of the square tube 2 and unable to enter. By setting the correction wheel 51 on the front side of the shell 31, the correction wheel 51 is driven to rotate while the support mechanism 3 advances, and during the rotation of the correction wheel 51, the protruding front end pushes the inwardly recessed end upward after contacting the misaligned part of the square tube 2, so that the two movable ends of the square tube 2 are recombined into a perpendicular state. At this time, the spot welder 39 located behind the correction wheel 51 will spot weld the part corrected last time. When the support mechanism 3 enters the inside of the square tube 2, the correction wheel 51 can still correct the square tube 2 in front of the support mechanism 3, so that during the advancement of the support mechanism 3, it will not be quickly worn due to severe friction with the inner wall of the inwardly recessed square tube 2, and at the same time, it ensures that the spot welded part is in a perpendicular state during spot welding, avoiding misaligned spot welding and avoiding misalignment and recess on the outer side after subsequent welding.

[0025] The distance between the rope entering through the wire port 32 on the front side of the shell 31 and the surface of the circular arc shaft 35 is always equal, avoiding the change in the length of the rope inside the shell 31 during winding, which causes the support mechanism 3 to advance different distances, resulting in unequal spot welding.

[0026] One end of the circular arc shaft 35 is fixedly connected with a coaxial prism 36, one side of the electromagnet 34 is fixedly connected with a stop frame 37 that moves obliquely upward to the shell 31, and the stop frame 37 is elastically connected between the inner wall of the shell 31 and the electromagnet 34.

[0027] When the electromagnet 34 is triggered and turned on under the action of magnetic attraction, it moves obliquely upward to the inner wall of the square tube 2, and when the electromagnet 34 moves, it drives the stop frame 37 to move, and when the stop frame 37 moves obliquely upward, the parallel inner side surface in it will contact the two parallel surfaces of the prism 36, so that the stop frame 37 clamps the prism 36, and the prism 36 and the circular arc shaft 35 cannot rotate, preventing the circular arc shaft 35 from rotating and causing the rope to loosen, causing the distance between the subsequent spot welded parts and the previous distance to be different, affecting the spot welding effect.

[0028] The left and right sides of the shell 31 are abutted with angle blocks 310, the angle blocks 310 are fixedly connected with a push frame 311 and a guide column 313 towards the side surface of the shell 31, the push frame 311 penetrates the shell 31 and extends into its interior, and the guide column 313 is slidingly connected in the shell 31.

[0029] The shape of the corner block 310 is an isosceles triangle, and the two oblique sides are perpendicular to each other, and the straight side faces the shell 31. When the support mechanism 3 enters the square tube 2, when the side length of the square tube 2 is greater than the size of the shell 31, at this time the inclined surface above the shell 31 does not contact the square tube 2, at this time the control pusher 311 is pushed outwards, so that the corner block 310 slides on the inclined surface below the square tube 2, when the right angle end of the corner block 310 contacts the two left and right symmetrical inner right angles of the square tube 2, the inclined surface above the shell 31 will contact the inner side of the square tube 2, so that the support mechanism 3 can support the square tube 2 with a side length within the processing range, and the application range of the device is wider.

[0030] The shell 31 is fixedly connected with a plurality of first telescopic rods 312 whose telescopic ends are fixedly connected with the pusher 311, and the telescopic ends of the plurality of first telescopic rods 312 are synchronously telescopic.

[0031] The synchronously telescopic first telescopic rods 312 make the moving speed of the two corner blocks 310 on the same side the same, ensuring that the shell 31 can keep a straight upward state when the two corner blocks 310 move outward, preventing the support mechanism 3 from deviating left and right when rising, so that the shell 31 cannot accurately contact the two inner sides above the square tube 2.

[0032] The output shaft of the motor 41 is fixedly sleeved with a driving gear 43, and the shaft of the circular arc shaft 35 is fixedly sleeved with a winding gear 44 engaged with the driving gear 43.

[0033] The straight bracket 12 is fixedly connected with a fixed stop block 15 at one end close to the rope hook 14, and is slidably connected with a sliding stop block 16 at one end away from the rope hook 14. The straight bracket 12 is threadedly connected with a threaded shaft 17 at one end, and the threaded shaft 17 is rotatably installed at one end on the side surface of the sliding stop block 16.

[0034] After the square tube 2 is placed on the straight bracket 12, the threaded shaft 17 is rotated to drive the sliding stop block 16 to move towards the square tube 2, so as to fix the square tube 2 on the straight bracket 12, ensuring the stability of the square tube 2 during spot welding.

[0035] The top surface of the base 11 is slidably connected with symmetrical sliding plates 13, which are driven by elastic members to move towards the center line of the base 11. The top surface of the sliding plate 13 is fixedly connected with a plurality of equidistant mounting clamps 7, and the straight bracket 12 is driven by the elastic member to slide upward in the base 11.

[0036] When the square tube 2 is placed on the straight bracket 12, the mounting clamps 7 are pushed outward due to the size of the square tube 2, so that the sliding plates 13 slide outward, and at the same time the straight bracket 12 also moves downward due to the size of the square tube 2, so that the bearing mechanism 1 can clamp square tubes 2 with different side lengths.

[0037] Since the sliding plate 13 is driven by the elastic member to move to the center line direction of the base 11, after the mounting clips 7 on both sides contact the edges on the left and right sides of the square tube 2, the square tube 2 is pressed inward, so that the two movable ends of the square tube 2 are abutted together, preventing the square tube 2 from being opened during the movement of the supporting mechanism 3.

[0038] The mounting clip 7 includes a bracket 71 fixedly connected to the sliding plate 13, an X wheel 72 rotatably installed in the bracket 71, a self-resetting stopper 73 hingedly connected in the bracket 71 and driven by a torsional spring, and a gas cylinder 74 fixedly connected in the bracket 71, wherein the free end of the self-resetting stopper 73 abuts against the X wheel 72, and the extension end of the gas cylinder 74 pushes the self-resetting stopper 73 to rotate to a horizontal position when extended.

[0039] When the square tube 2 is placed from top to bottom, the edges on the left and right sides of the square tube 2 contact the X wheel 72, at this time the X wheel 72 is pushed downward, and when the square tube 2 is placed, the X wheel 72 cannot rotate reversely under the obstruction of the self-resetting stopper 73, thereby avoiding the upward movement of the square tube 2 under the upward pushing of the elastic member at the bottom of the right-angle frame 12, and since the outer wall of the square tube 2 also contacts the inclined edge of the bracket 71 facing the square tube 2, the square tube 2 cannot move downward, so that the square tube 2 cannot move upward after being placed on the right-angle frame 12 through the mounting clip 7, and the square tube 2 can be fixed on the right-angle frame 12 by the fixed stopper 15 and the sliding stopper 16, thereby preventing the displacement of the square tube 2 during spot welding and ensuring accurate spot welding.

[0040] When the square tube 2 is processed, the extension end of the gas cylinder 74 is controlled to extend, so that the self-resetting stopper 73 no longer contacts the X wheel 72, thereby enabling the square tube 2 to be lifted upward for transfer, and after the square tube 2 is removed, the extension end of the gas cylinder 74 is retracted, and the self-resetting stopper 73 is automatically reset under the action of the torsional spring.

[0041] The correction mechanism 5 further includes a protective shell 52 fixedly connected to the front side of the shell 31, wherein the protective shell 52 is provided with a synchronous wheel 53 and a synchronous belt 54, and the rotating shafts of the motor 41 and the correction wheel 51 are both fixedly sleeved with the synchronous wheel 53.

[0042] Through the transmission of the synchronous wheel 53 and the synchronous belt 54, the motor 41 not only drives the circular arc shaft 35 to rotate and wind the rope, but also drives the correction wheel 51 to rotate, and with the rotation of the correction wheel 51, the inwardly misaligned square tube 2 is pushed outward, thereby correcting the inward misalignment of the square tube 2 due to lifting and bending errors, and ensuring that the spot welding areas are in a perpendicular state during spot welding.

[0043] The bottom of the shell 31 is provided with a walking mechanism 6, the walking mechanism 6 comprises a second telescopic rod 61 and a wheel frame 62, a side surface of the wheel frame 62 is rotatably provided with a matching wheel 63, a bottom surface of the wheel frame 62 is rotatably provided with a aligning wheel 64, the wheel frame 62 is fixedly connected to the telescopic end of the second telescopic rod 61, and a downward inclined lifting slope 65 is formed in the side of the wheel frame 62, which faces the square tube 2.

[0044] Through the cooperation of the aligning wheel 64 and the two corner blocks 310, the supporting mechanism 3 can be vertically moved upwards, the stability of the supporting mechanism 3 during upward movement is ensured, and the situation that the oblique side surface above the shell 31 first contacts the inner wall of the square tube 2 and then rubs against the inner wall of the square tube 2 during subsequent upward movement is avoided, so that the shell 31 is not rapidly worn on one side, the gravity center of the shell 31 is not offset, and the two oblique side surfaces above the shell 31 are no longer symmetrical along the center line of the shell 31, the supporting and spot welding effects are affected, and meanwhile, the two corner blocks 310 and the aligning wheel 64 form three-point positioning, so that the supporting mechanism 3 is more stable during forward movement.

[0045] The above only describes certain exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the present application.
