Description

Technical Field

[0001] The invention belongs to the technical field of welding equipment, in particular to welding equipment for mining machinery production. Background Art

[0002] In the field of mining machinery, traditional mechanical structures have limitations. T-frames are widely used in mining machinery, such as supporting mining heads and transportation equipment, due to their unique design, high strength, good stability, and ability to withstand large loads. Therefore, the use of T-frames in mining machinery can improve the performance and reliability of mining machinery and promote efficient and safe production. The T-frame is welded by a horizontal plate and a vertical plate. Before welding, the operator moves the two plates to the welding table, places the horizontal plate horizontally, and places the vertical plate vertically on the horizontal plate, and ensures that the two ends of the horizontal plate and the vertical plate are aligned before welding. Since the main materials of the horizontal plate and the vertical plate are steel plates, the operator will spend a lot of time every time he moves the horizontal plate and the vertical plate, and adjusts the two, which reduces the welding efficiency of the T-frame. Therefore, in order to solve the above problems, a welding device for mining machinery production is proposed. Summary of the invention

[0003] In order to solve the problems raised in the above background technology, the present invention provides a welding device for mining machinery production, which solves the problem that operators currently spend a lot of time each time moving horizontal plates and vertical plates and adjusting the two.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a welding device for mining machinery production, comprising a support platform, a storage rack, a welding mechanical arm, a horizontal plate and a vertical plate, wherein the storage rack is installed on the support platform for storing the horizontal plate, and further comprising: a feeding assembly, which is arranged on the support platform for feeding the vertical plate; a damping roller assembly, which is symmetrically installed on the feeding assembly for clamping and slowing down the descending speed of the vertical plate; an elastic support plate, which is symmetrically hinged just below the feeding assembly for supporting the horizontal plate; a push plate, which is movably installed on the support platform; a driving assembly, which is arranged on the support platform for driving the push plate to move back and forth;

[0005] A ball bearing plate located directly below the storage rack is fixedly connected to the support platform, and balls for supporting the horizontal plate are equidistantly arranged on the top of the ball bearing plate;

[0006] The top of the support platform is also symmetrically fixed with a fixed block. When the push plate pushes the bottommost horizontal plate in the storage rack to abut against the fixed block, the horizontal plate is above the two elastic support plates;

[0007] The feeding assembly includes a funnel frame and an intermittent conveyor belt, the funnel frame is fixed to the support platform, the vertical plate can fall from the top of the funnel frame to the bottom, the intermittent conveyor belt is used to convey the vertical plate to the top of the funnel frame when the cross plate is directly above the two elastic support plates, and the height of the bottom outlet of the funnel frame is lower than the height of the vertical plate;

[0008] The minimum distance between the storage rack and the elastic support plate in the horizontal direction is less than half the length of the push plate;

[0009] The support platform is also provided with an adjustment component for locking or releasing the elastic support plate when the push plate reciprocates;

[0010] The support platform is provided with a feeding port located just below the feeding assembly for the transverse plate to pass through.

[0011] Preferably, the welding robot arm is arranged on a support platform, a material unloading rack is installed at the bottom of the support platform, and the top of the material unloading rack is located directly below the material unloading port.

[0012] Preferably, the thickness of the push plate is smaller than that of the cross plate, and a plurality of supporting rollers are equidistantly and movably connected to the top of the push plate.

[0013] Preferably, the support platform is symmetrically equipped with limit position components;

[0014] The limiting assembly comprises an L-shaped block fixedly connected to the support platform, and two limiting assemblies are fixedly connected to limiting rods on opposite sides, and the limiting rods are provided with elastic inclined blocks elastically connected to the L-shaped block;

[0015] The transverse plate can press the elastic inclined block when moving toward the elastic inclined block.

[0016] Preferably, the end of the elastic inclined block away from the push plate is a vertical surface.

[0017] Preferably, the damping roller assembly comprises a mounting frame symmetrically fixed to the funnel frame, a frame body symmetrically fixed to the mounting frame, and a damping roller body movably connected to the frame body;

[0018] The distance between two damping roller bodies at the same height is less than the thickness of the transverse plate;

[0019] When the vertical plate falls onto the horizontal plate, the two groups of damping roller bodies at the bottom contact with the two surfaces of the vertical plate respectively.

[0020] Preferably, ratchets are fixedly connected to the rotating shafts at both ends of the damping roller body, and ratchets for limiting the unidirectional rotation of the ratchets are elastically hinged at both ends of the frame body.

[0021] Preferably, the adjustment assembly comprises a bar block symmetrically fixed on the support platform, a U-shaped frame is movably connected to the outside of the bar block, and the U-shaped frame and the bar block are connected by a tension spring;

[0022] Initially, one end of the push plate away from the elastic support plate abuts against the U-shaped frame and causes the tension spring to be in a stretched state.

[0023] Preferably, the elastic support plate is provided with slots at equal intervals, and protrusions are fixedly connected at equal intervals on one side of the elastic support plate away from each other;

[0024] The portion of the U-shaped frame located above the notch is fixedly connected with a pressing block overlapping the notch in the vertical direction;

[0025] When the push plate moves toward the elastic support plate, the abutment against the U-shaped frame can be released, and at the same time, the U-shaped frame can drive the pressing block to move above the protrusion under the tension of the tension spring.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The above scheme drives the push plate to move the cross plate by running the driving assembly. When the cross plate is against the fixed block toward the fixed block, the cross plate is located above the elastic support plate. At the same time, the driving assembly runs and drives the push plate to move slowly in the opposite direction. Then, the intermittent conveyor belt runs to transport the vertical plate to the top of the funnel frame, so that the vertical plate falls from the bottom of the funnel frame to the top of the cross plate. Since the top of the vertical plate is limited, the cross plate and the vertical plate cooperate to form an inverted "T" shape, thereby completing the loading of the two groups of plates, solving the problem that the operator spends a lot of time each time when carrying the cross plate and the vertical plate and adjusting the two;

[0028] When the cross plate moves toward the elastic support plate through the above scheme, the cross plate will squeeze the inclined surface of the elastic inclined block and make the two groups of elastic inclined blocks move back to each other. When the cross plate is toward the fixed block side and abuts against the fixed block, when the cross plate is located above the elastic support plate and the push plate moves in the opposite direction and is free from squeezing the elastic inclined block, the elastic inclined block is reset by its own elastic force to limit the cross plate toward the elastic inclined block side, thereby ensuring the stability of both ends of the cross plate during welding positioning;

[0029] In the above scheme, the vertical plate moves downward along the inner wall of the funnel frame, so that the two sides of the vertical plate will contact the two groups of damping roller bodies respectively, and the damping roller bodies will also slow down the falling speed of the vertical plate, so as to prevent the vertical plate from falling too fast and colliding with the horizontal plate, thereby causing the horizontal plate to vibrate and deviate from the predetermined position;

[0030] The above scheme slowly resets the push plate. When the push plate begins to contact and squeeze the U-frame, the U-frame drives the pressure block to move and coincide with the notch. Under the action of gravity, the welded T-frame squeezes the two sets of elastic support plates to rotate, so that the T-frame falls from the unloading port to the unloading rack, and finally the unloading operation is performed along the unloading rack.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] like Figures 1 to 10 As shown, the present invention provides a welding device for mining machinery production, including a support platform 1, a storage rack 11, a welding mechanical arm 15, a horizontal plate 91 and a vertical plate 92, wherein the storage rack 11 is installed on the support platform 1 for storing the horizontal plate 91, and further includes: a feeding assembly 4, which is arranged on the support platform 1 for feeding the vertical plate 92; a damping roller assembly 5, which is symmetrically installed on the feeding assembly 4 for clamping and slowing down the descending speed of the vertical plate 92; an elastic support plate 6, which is symmetrically hinged just below the feeding assembly 4 for supporting the horizontal plate 91; a push plate 2, which is movably installed on the support platform 1; a driving assembly 3, which is arranged on the support platform 1 for driving the push plate 2 to move back and forth;

[0044] A ball bearing plate 22 is fixedly connected to the support platform 1 and is located directly below the storage rack 11. Ball bearings for supporting the horizontal plate 91 are equidistantly arranged on the top of the ball bearing plate 22.

[0045] The top of the support platform 1 is also symmetrically fixed with a fixed block 13. When the push plate 2 pushes the bottommost horizontal plate 91 in the storage rack 11 to abut against the fixed block 13, the horizontal plate 91 is above the two elastic support plates 6;

[0046] The feeding assembly 4 includes a funnel frame 41 and an intermittent conveyor belt 42. The funnel frame 41 is fixed to the support platform 1. The vertical plate 92 can drop from the top of the funnel frame 41 to the bottom. The intermittent conveyor belt 42 is used to convey the vertical plate 92 to the top of the funnel frame 41 when the horizontal plate 91 is directly above the two elastic support plates 6. The height of the bottom outlet of the funnel frame 41 is lower than the height of the vertical plate 92.

[0047] The minimum distance between the storage rack 11 and the elastic support plate 6 in the horizontal direction is less than half the length of the push plate 2;

[0048] The support platform 1 is also provided with an adjustment component 8 for locking or releasing the elastic support plate 6 when the push plate 2 moves back and forth;

[0049] The support platform 1 is provided with a feed opening 14 located directly below the feed assembly 4 for the cross plate 91 to pass through;

[0050] By adopting the above scheme, the push plate 2 is driven by the operation of the driving assembly 3 to push the horizontal plate 91 to move. When the horizontal plate 91 is against the fixed block 13 toward the side of the fixed block 13, the horizontal plate 91 is located above the elastic support plate 6. At the same time, the driving assembly 3 is operated and drives the push plate 2 to slowly move in the opposite direction. Then, the intermittent conveyor belt 42 is operated to convey the vertical plate 92 to the top of the funnel frame 41, so that the vertical plate 92 falls from the bottom of the funnel frame 41 to the top of the horizontal plate 91. Since the top of the vertical plate 92 is limited, the horizontal plate 91 and the vertical plate 92 cooperate to present an inverted "T" shape, thereby completing the loading of the two groups of plates.

[0051] At the same time, since the minimum distance between the storage rack 11 and the elastic support plate 6 in the horizontal direction is less than half the length of the push plate 2, it is ensured that when the push plate 2 pushes the cross plate 91 onto the elastic support plate 6, the push plate 2 and the storage rack 11 always have an overlapping part in the vertical direction;.

[0052] like Figure 1-4 As shown in FIG. 8 , the welding robot arm 15 is disposed on the support platform 1 , a material unloading rack 12 is installed at the bottom of the support platform 1 , and the top of the material unloading rack 12 is located directly below the material unloading port 14 ;

[0053] The thickness of the push plate 2 is smaller than that of the horizontal plate 91, and a plurality of support rollers 21 are movably connected to the top of the push plate 2 at equal intervals;

[0054] By adopting the above scheme, when the bottommost horizontal plate 91 in the storage rack 11 is pushed away from the storage rack 11 by the push plate 2, the support roller 21 will support the bottom surface of the next horizontal plate 91 in the storage rack 11, and at the same time reduce the friction between the push plate 2 and the bottom surface of the next horizontal plate 91.

[0055] like Figure 1-4 , Figure 8 and Fig.10 As shown, the limiting assembly 7 is symmetrically installed on the support platform 1;

[0056] The limiting assembly 7 comprises an L-shaped block 71 fixedly connected to the support platform 1, and two limiting rods 72 are fixedly connected to opposite sides of the two limiting assemblies 7, and an elastic inclined block 73 elastically connected to the L-shaped block 71 is disposed on the outer sleeve of the limiting rod 72;

[0057] When the horizontal plate 91 moves toward the elastic inclined block 73, it can squeeze the elastic inclined block 73;

[0058] The end of the elastic inclined block 73 away from the push plate 2 is a vertical surface;

[0059] When the above scheme is adopted, when the cross plate 91 moves toward the elastic support plate 6, the cross plate 91 will squeeze the inclined surface of the elastic inclined block 73 and make the two groups of elastic inclined blocks 73 move away from each other. When the cross plate 91 is toward the side of the fixed block 13 and abuts against the fixed block 13, when the cross plate 91 is located above the elastic support plate 6 and the push plate 2 moves in the opposite direction and disengages from the squeezing of the elastic inclined block 73, the elastic inclined block 73 is reset by its own elastic force to limit the cross plate 91 toward the side of the elastic inclined block 73, thereby ensuring the stability of both ends of the cross plate 91 during welding positioning.

[0060] like Figure 1 , Figure 3 , Figure 6-7 and Fig. 9 As shown, the damping roller assembly 5 includes a mounting frame 51 symmetrically fixed to the funnel frame 41, a frame body 52 symmetrically fixed to the mounting frame 51, and a damping roller body 53 movably connected to the frame body 52;

[0061] The distance between the two damping roller bodies 53 at the same height is smaller than the thickness of the transverse plate 91;

[0062] When the vertical plate 92 falls on the horizontal plate 91, the two groups of damping roller bodies 53 below contact the two surfaces of the vertical plate 92 respectively;

[0063] Ratchet wheels 54 are fixedly connected to the rotating shafts at both ends of the damping roller body 53, and ratchet teeth 55 for limiting the unidirectional rotation of the ratchet wheel 54 are elastically hinged at both ends of the frame body 52;

[0064] With the above solution, the vertical plate 92 moves downward along the inner wall of the funnel frame 41, so that the two sides of the vertical plate 92 will contact the two groups of damping roller bodies 53 respectively, and the damping roller bodies 53 will also slow down the falling speed of the vertical plate 92, so as to prevent the vertical plate 92 from falling too fast and colliding with the horizontal plate 91, thereby causing the horizontal plate 91 to vibrate and deviate from the predetermined position.

[0065] At the same time, the rotation direction of the ratchet 54 is limited by the ratchet teeth 55. When the bottom of the vertical plate 92 contacts the horizontal plate 91, it can also limit the vertical plate 92 in the vertical direction, thereby ensuring the stability of the welding robot arm 15 when welding the horizontal plate 91 and the vertical plate 92.

[0066] like Figure 1-3 , Figure 6 , Figure 8 and Fig.10 As shown, the adjustment assembly 8 includes a bar block 82 symmetrically fixed to the support platform 1, a U-shaped frame 81 is movably connected to the bar block 82, and the U-shaped frame 81 and the bar block 82 are connected by a tension spring 83;

[0067] Initially, the end of the push plate 2 away from the elastic support plate 6 abuts against the U-shaped frame 81 and causes the tension spring 83 to be in a stretched state;

[0068] The elastic support plate 6 is provided with slots 61 at equal intervals, and protrusions 62 are fixedly connected at equal intervals on one side of the elastic support plate 6 that is away from each other;

[0069] The portion of the U-shaped frame 81 located above the notch 61 is fixedly connected with a pressing block 811 which overlaps the notch 61 in the vertical direction;

[0070] When the push plate 2 moves toward the elastic support plate 6, the contact with the U-shaped frame 81 can be released. At the same time, the U-shaped frame 81 is pulled by the tension spring 83 to drive the pressing block 811 to move above the protrusion 62.

[0071] By adopting the above scheme, the push plate 2 is slowly reset. When the push plate 2 begins to contact and squeeze the U-shaped frame 81, the U-shaped frame 81 drives the pressure block 811 to move and overlap with the notch 61. Under the action of gravity, the welded T-shaped frame squeezes the two sets of elastic support plates 6 to rotate, so that the T-shaped frame falls from the unloading port 14 to the unloading rack 12, and finally the unloading operation is performed along the unloading rack 12.

[0072] The working principle and use process of the present invention:

[0073] First, the driving assembly 3 is operated to drive the push plate 2 to push the horizontal plate 91 to move. At this time, the U-shaped frame 81 is driven by the tension of the tension spring 83 to drive the pressing block 811 to move and be displaced with the notch 61 in the vertical direction, so that the pressing block 811 overlaps with the protrusion 62, thereby limiting the rotation direction of the elastic support plate 6;

[0074] At the same time, the cross plate 91 will also squeeze the inclined surface of the elastic inclined block 73 when moving, and respectively make the two groups of elastic inclined blocks 73 move back to each other. When the cross plate 91 is against the fixed block 13 toward the side of the fixed block 13, the cross plate 91 is located above the elastic support plate 6, and the driving assembly 3 is running and drives the push plate 2 to move slowly in the opposite direction. At this time, the elastic inclined block 73 is reset by its own elastic force to limit the cross plate 91 toward the side of the elastic inclined block 73. Then the intermittent conveyor belt 42 runs to convey the vertical plate 92 to the top of the funnel frame 41, so that the vertical plate 92 falls from the bottom of the funnel frame 41 to the top of the cross plate 91. Since the top of the vertical plate 92 is limited, the cross plate 91 and the vertical plate 92 cooperate to present an inverted "T" shape. At this time, the welding robot arm 15 runs to weld the cross plate 91 and the vertical plate 92;

[0075] When the vertical plate 92 moves downward along the inner wall of the funnel frame 41, the two sides of the vertical plate 92 will contact the two groups of damping roller bodies 53 respectively, and the damping roller bodies 53 will also slow down the falling speed of the vertical plate 92 to prevent the vertical plate 92 from falling too fast and colliding with the horizontal plate 91, thereby causing the horizontal plate 91 to vibrate and deviate from the predetermined position;

[0076] After welding is completed, the push plate 2 starts to contact and squeeze the U-shaped frame 81, so that the U-shaped frame 81 drives the pressing block 811 to move and overlap the notch 61. At this time, under the action of gravity, the T-shaped frame after welding squeezes the two sets of elastic support plates 6 to rotate, so that the T-shaped frame falls from the unloading port 14 to the unloading frame 12, and finally slides along the unloading frame 12;

[0077] When the elastic support plate 6 is reset by the elastic force, the driving assembly 3 pushes the push plate 2 to repeat the above operation.
