Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of metal processing, in particular to a metal plate processing device. Background Art
[0002] Sheet metal parts are products processed by sheet metal technology. We can't live without sheet metal parts in our lives. Sheet metal parts are made by laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, metal sheet bending, die forging, water jet cutting, precision welding and other processes.
[0003] When metal plates are being processed, fixed nuts can be welded on the outer surface of the plates so that the plates can be combined with other components by screw connection to achieve the desired effect when in use. Since the nuts are smaller than the plates and the nuts need to be precisely aligned with the screw holes of the plates, the nuts may be offset from the plates due to the contact of the welding ends during welding, resulting in misalignment between the nuts and the screw holes after welding, making it impossible to connect and use the plates normally. Therefore, improvements are needed. Summary of the invention
[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems by adopting a technical solution: a metal sheet processing device, comprising a control console and a support table, the bottom of the control console is symmetrically slid with processing parts, and the upper surface of the support table is provided with a processing plate; The processing plate comprises a drilling plate, the upper surface of which is evenly provided with fixing nuts, and each hole of the drilling plate is provided with a fixing nut, and the fixing nut is welded to the drilling plate by welding, so that the drilling plate can be combined with other components through the bolt connection of the fixing nut; The processing component includes a accommodating sleeve, a guide slide disk is fixedly connected to the top of the outer surface of the accommodating sleeve, a power supply top cylinder is fixedly connected to the top of the inner wall of the accommodating sleeve, a rotating motor is fixedly connected to the axis center of the bottom of the power supply top cylinder, and a two-way push cylinder is fixedly connected to the bottom end of the output shaft of the rotating motor. Telescopic push rods are symmetrically arranged on both sides of the inner cavity of the two-way push cylinder, and the two-way push cylinder can control the telescopic push rods at both ends to lengthen or shorten the deformation, and the end of the telescopic push rod away from the two-way push cylinder is fixedly connected to the guide slide cylinder, and control wheels are symmetrically arranged on both sides of the inner wall of the guide slide cylinder, a welding rod is slidably connected to the axis center of the inner wall of the guide slide cylinder, the bottom end of the telescopic push rod is fixedly connected to a docking rod, and the bottom end of the guide slide cylinder is slidably connected to a guide swivel.
[0005] The beneficial effect of the present invention is that the device welds the fixing nut to the upper surface of the drilled plate through the welding rod of the processing part, and because the butt plug rod in the middle can penetrate the hole of the drilled plate and the fixing nut during the welding process, the fixing nut is always aligned with the hole of the drilled plate during the welding process. The contact of the welding rod will not cause the fixing nut to slip relative to the drilled plate during welding, thereby causing the nut and the screw hole after welding to be misaligned, so that the plate cannot be connected and used normally.
[0006] Furthermore, there are two welding rods, the bottom end of which extends to the outside of the guide swivel through the through hole, the outer surface of the guide swivel is rotatably connected to the bottom of the inner cavity of the accommodating sleeve, and the top end of the welding rod is fixedly connected to the inner cavity of the power supply top cylinder through a connecting wire. The outer surface of the welding rod is rotatably connected to the outer surface of the control wheel, the top of the guide sliding plate is slidably connected to the inner wall of the console, the top of the console is slidably connected to the ceiling through a pull rod, and the bottom end of the docking rod is plugged into the inner cavity of the drilling plate through the through hole.
[0007] After adopting the above-mentioned further structure, since the welding rod performs comprehensive welding work on the bottom of the fixing nut by surrounding the fixing nut, the fixing effect of the fixing nut after welding is more firmly. However, the outer surface of the fixing nut is not circular, so during the surrounding welding process, the welding rod also needs to adjust the actual distance between the welding rod and the side of the fixing nut through the telescopic push rod, so that the welding rod can slide along the slide groove of the rotating shell, thereby avoiding the problem that the welding rod is blocked by the fixing nut when rotating, thereby preventing the welding work from being carried out normally.
[0008] Furthermore, the guide swivel includes a rotating shell, and inner push plates are symmetrically fixed on both sides of the inner cavity of the rotating shell, and arc-shaped sliding arms are symmetrically arranged at both ends of the inner push plates. The outer surface of the arc-shaped sliding arm is slidably connected to the inner wall of the rotating shell, and the end of the arc-shaped sliding arm away from the inner push plate is squeezed against the outer surface of the welding rod through a sliding groove. The welding rod can slide along the sliding grooves on both sides of the rotating shell, and after the arc-shaped sliding arm is pushed open, its end portion can squeeze the outer surface of the welding rod, thereby fixing the welding rod.
[0009] Furthermore, the support platform includes a load-bearing bottom shell, and vertical pressure rods are symmetrically arranged on the front and rear sides of the inner cavity of the load-bearing bottom shell, and the bottom end of the vertical pressure rod is fixedly connected to a pressure spring belt through a connecting plate, and the bottom end of the pressure spring belt is fixedly connected to a pressure-bearing inner plate, and the top end of the vertical pressure rod and the lower surface of the drilled plate are mutually compressed. The top end of the vertical pressure rod extends to the outside of the load-bearing bottom shell, and the outer surface of the vertical pressure rod is slidably connected to the inner cavity of the load-bearing bottom shell, the outer surface of the pressure-bearing inner plate is fixedly connected to the inner cavity of the load-bearing bottom shell, and a guide component is arranged in the middle of the inner wall of the load-bearing bottom shell.
[0010] After adopting the above-mentioned further structure, when placing the drilled plate, the drilled plate will first be squeezed with the vertical pressure rod on the top of the load-bearing bottom shell, and then the vertical pressure rod will trigger the pressure-bearing inner plate at the bottom by compressing the pressure spring belt. The stability of the drilled plate is judged by the pressure value of the pressure-bearing inner plate. If the drilled plate shakes relative to the support platform, the squeezing force of the vertical pressure rod on the pressure-bearing inner plate will also change. The pressure spring belt can provide a certain buffering effect on the drilled plate. During the downward pressing process of the control console, the drilled plate is simultaneously pushed down to prevent the processing parts from being pressed down too long, thereby preventing the drilled plate from being damaged.
[0011] Furthermore, the guide component includes a clustering median plate, the middle of the inner cavity of the clustering median plate is fixedly connected with a protective shell, the bottom of the inner wall of the protective shell is fixedly connected with an adsorption inner cylinder, and the top of the inner wall of the protective shell is fixedly connected with an adsorption mesh cover. The upper surface of the adsorption mesh cover and the axis of the lower surface of the drilled plate are mutually squeezed, the outer surface of the clustering median plate is fixedly connected with the middle of the inner wall of the load-bearing bottom shell, and the upper part of the inner cavity of the protective shell is evenly provided with through-gas ports, and the through-gas ports are butted with the exhaust port of the adsorption inner cylinder.
[0012] Furthermore, the inner cavity of the cluster median plate is symmetrically provided with a spring sleeve, the top end of the spring sleeve output shaft is fixedly connected with a plug-in bottom rod, the bottom end of the docking rod is provided with a groove that can complement the top end of the round head of the plug-in bottom rod, and the outer diameter of the docking rod is the same as the outer diameter of the plug-in bottom rod, and both can completely penetrate the fixing nut, the outer surface of the plug-in bottom rod is slidably connected to the inner wall of the drilled plate through the bolt mouth, and the top end of the plug-in bottom rod extends to the inside of the fixing nut.
[0013] After adopting the above-mentioned further structure, since the guiding component is arranged in the middle area of the load-bearing bottom shell, when placing the drilled plate, the four plug-in bottom rods will penetrate the holes of the drilled plate, and then guide the socketing work of the fixing nut through the plug-in bottom rods. In this way, when the processing component has not yet contacted the fixing nut, the fixing nut can also be relatively stably restricted to the hole position of the drilled plate, and the drilled plate can be simply stabilized by the negative pressure of the adsorption mesh cover, preventing the drilled plate from tilting, causing the fixing nut to be unable to stably contact the upper surface of the drilled plate, resulting in a larger welding gap.

DETAILED DESCRIPTION
[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses. Example 1, please refer to Figure 1-Figure 6 , the present invention provides a technical solution: a metal sheet processing equipment, comprising a control console 1 and a support table 4, a processing component 2 is symmetrically slid on the bottom of the control console 1, and a processing plate 3 is arranged on the upper surface of the support table 4; The processing plate 3 includes a drilling plate 31, and fixing nuts 32 are evenly arranged on the upper surface of the drilling plate 31. A fixing nut 32 is arranged on each hole of the drilling plate 31, and the fixing nut 32 is welded to the drilling plate 31 by welding, so that the drilling plate 31 can be combined with other components through the bolt connection of the fixing nut 32; The processing component 2 includes a accommodating sleeve 21, a guide slide 23 is fixedly connected to the top of the outer surface of the accommodating sleeve 21, a power supply top cylinder 22 is fixedly connected to the top of the inner wall of the accommodating sleeve 21, a rotating motor 24 is fixedly connected to the axis center of the bottom of the power supply top cylinder 22, a two-way push cylinder 26 is fixedly connected to the bottom end of the output shaft of the rotating motor 24, telescopic push rods 27 are symmetrically arranged on both sides of the inner cavity of the two-way push cylinder 26, the two-way push cylinder 26 can control the telescopic push rods 27 at both ends to lengthen or shorten the deformation, the end of the telescopic push rod 27 away from the two-way push cylinder 26 is fixedly connected to a guide slide cylinder 28, control wheels 29 are symmetrically arranged on both sides of the inner wall of the guide slide cylinder 28, a welding rod 210 is slidably connected to the axis center of the inner wall of the guide slide cylinder 28, the bottom end of the telescopic push rod 27 is fixedly connected to the docking rod 25, and the bottom end of the guide slide cylinder 28 is slidably connected to the guide swivel 6.
[0017] There are two welding rods 210. The bottom end of the welding rod 210 extends to the outside of the guide swivel 6 through the through hole. The outer surface of the guide swivel 6 is rotatably connected to the bottom of the inner cavity of the accommodating sleeve 21. The top of the welding rod 210 is fixedly connected to the inner cavity of the power supply top cylinder 22 through a connecting wire. The outer surface of the welding rod 210 is rotatably connected to the outer surface of the control wheel 29. The top of the guide slide plate 23 is slidably connected to the inner wall of the console 1. The top of the console 1 is slidably connected to the ceiling through a pull rod. The bottom end of the docking rod 25 is plugged into the inner cavity of the drilling plate 31 through the through hole.
[0018] The guide swivel 6 includes a rotating shell 61, and inner push plates 62 are symmetrically fixed on both sides of the inner cavity of the rotating shell 61. Arc-shaped sliding arms 63 are symmetrically arranged at both ends of the inner push plates 62. The outer surface of the arc-shaped sliding arm 63 is slidably connected to the inner wall of the rotating shell 61, and the end of the arc-shaped sliding arm 63 away from the inner push plate 62 is squeezed against the outer surface of the welding rod 210 through a sliding groove. The welding rod 210 can slide along the sliding grooves on both sides of the rotating shell 61, and after the arc-shaped sliding arm 63 is pushed open, its end portion can squeeze the outer surface of the welding rod 210, thereby fixing the welding rod 210.
[0019] The main function of the device is to weld the bulk fixing nuts 32 to the upper surface of the drilling plate 31. When actually working, the drilling plate 31 is placed flat on the support table 4, and then a fixing nut 32 is placed at each hole of the drilling plate 31, and then the console 1 is moved to the position facing the fixing nut 32 and pressed down.
[0020] The docking rod 25 at the bottom end of the processing component 2 is first inserted into the hole of the drilling plate 31 through the fixing nut 32 and penetrates through it. At this time, the fixing nut 32 will not be misaligned with the hole of the drilling plate 31 during welding. Then the welding rods 210 on both sides can weld the bottom of the fixing nut 32 and the upper surface of the drilling plate 31. During the welding process, the rotating motor 24 can pull the guide slides 28 on both sides to rotate axially by twisting the two-way push cylinder 26. At this time, the welding rod 210 can drive the guide swivel 6 to rotate freely along the bottom of the accommodating sleeve 21.
[0021] Since the outer surface of the fixing nut 32 is not circular, the welding rod 210 needs to adjust the actual distance between the welding rod 210 and the side of the fixing nut 32 through the telescopic push rod 27 during the circumferential welding process, so that the welding rod 210 can slide along the slide groove of the rotating shell 61, thereby avoiding the problem that the welding rod 210 is blocked by the fixing nut 32 during rotation, thereby preventing the welding work from being carried out normally.
[0022] During welding, the guide slide 28 can drive the welding rod 210 to slide vertically through the control wheel 29 on the inner wall, so the welding point at the bottom end of the welding rod 210 can be changed. By sliding the welding rod 210, fine-tuning can be performed again to make the gap between the bottom end of the welding rod 210 and the fixing nut 32 and the drilled plate 31 closer, thereby avoiding the problem that the welding rod 210 cannot contact the effective welding point.
[0023] When the bottom end of the welding rod 210 contacts the bottom of the fixing nut 32, the arc-shaped sliding arms 63 at both ends of the inner push plate 62 are pushed open. At this time, the arc-shaped sliding arms 63 can clamp the outer surface of the welding rod 210, so that the slidable welding rod 210 is in a fixed state, thereby ensuring the stability of the welding work.
[0024] Example 2, please refer to Figure 1-Figure 8 The present invention provides a technical solution: on the basis of embodiment 1, the support platform 4 includes a load-bearing bottom shell 41, and vertical pressure rods 42 are symmetrically arranged on the front and rear sides of the inner cavity of the load-bearing bottom shell 41, and the bottom end of the vertical pressure rod 42 is fixedly connected to a pressure spring belt 43 through a connecting plate, and the bottom end of the pressure spring belt 43 is fixedly connected to a pressure inner plate 44, and the top end of the vertical pressure rod 42 and the lower surface of the drilling plate 31 are pressed against each other. The top end of the vertical pressure rod 42 extends to the outside of the load-bearing bottom shell 41, and the outer surface of the vertical pressure rod 42 is slidably connected to the inner cavity of the load-bearing bottom shell 41, and the outer surface of the pressure inner plate 44 is fixedly connected to the inner cavity of the load-bearing bottom shell 41, and the middle part of the inner wall of the load-bearing bottom shell 41 is provided with a guide component 5.
[0025] The guide component 5 includes a clustering middle plate 51, a protective shell 55 is fixedly connected to the middle of the inner cavity of the clustering middle plate 51, an adsorption inner cylinder 54 is fixedly connected to the bottom of the inner wall of the protective shell 55, and an adsorption mesh cover 56 is fixedly connected to the top of the inner wall of the protective shell 55. The upper surface of the adsorption mesh cover 56 is mutually squeezed with the axis of the lower surface of the drilled plate 31, the outer surface of the clustering middle plate 51 is fixedly connected to the middle of the inner wall of the load-bearing bottom shell 41, and the upper part of the inner cavity of the protective shell 55 is evenly provided with through-gas ports, and the through-gas ports are butted with the exhaust port of the adsorption inner cylinder 54.
[0026] The inner cavity of the clustering median plate 51 is symmetrically provided with a spring sleeve 52, and the top end of the output shaft of the spring sleeve 52 is fixedly connected with a plug-in bottom rod 53, and the bottom end of the docking rod 25 is provided with a groove that can complement the top end of the round head of the plug-in bottom rod 53, and the outer diameter of the docking rod 25 is the same as the outer diameter of the plug-in bottom rod 53, and both can completely penetrate the fixing nut 32, and the outer surface of the plug-in bottom rod 53 is slidably connected to the inner wall of the drilled plate 31 through the bolt mouth, and the top end of the plug-in bottom rod 53 extends to the inside of the fixing nut 32.
[0027] When the drilling plate 31 is placed, the drilling plate 31 will first be squeezed by the vertical pressure rod 42 on the top of the load-bearing bottom shell 41, and then the vertical pressure rod 42 will trigger the pressure-bearing inner plate 44 at the bottom by compressing the pressure spring belt 43. The stability of the drilling plate 31 is judged by the pressure value of the pressure-bearing inner plate 44. If the drilling plate 31 shakes relative to the support platform 4, the squeezing force of the vertical pressure rod 42 on the pressure-bearing inner plate 44 will also change. The pressure spring belt 43 can provide a certain buffering effect on the drilling plate 31, and when the console 1 is pressed down, the drilling plate 31 is simultaneously pushed down.
[0028] When the upper surface of the adsorption mesh cover 56 is in contact with the lower surface of the drilled plate 31, the adsorption inner cylinder 54 will simply fix the drilled plate 31 on the upper part of the support platform 4 by depressurizing and adsorbing, so as to prevent the drilled plate 31 from slipping.
[0029] Since the guide component 5 is arranged in the middle area of the load-bearing bottom shell 41, when the drilling plate 31 is placed, the four plug-in bottom rods 53 will pass through the holes of the drilling plate 31, and then guide the socketing work of the fixing nut 32 through the plug-in bottom rods 53, so that when the processing component 2 has not yet contacted the fixing nut 32, the fixing nut 32 can also be relatively stably restricted in the hole position of the drilling plate 31, and when the docking rod 25 is inserted into the drilling plate 31 from top to bottom, it will first dock with the top end of the plug-in bottom rod 53, and then press the plug-in bottom rod 53 downward, thereby realizing the effect of restricting the fixing nut 32 by alternately plugging the bottom rod 53 through the docking rod 25.
[0030] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
