Description

Technical Field

[0001] The present invention relates to the technical field of roller stands, and particularly to an adjustable roller stand. Background Art

[0002] A roller stand is a welding auxiliary device mainly used for welding cylindrical workpieces. It drives the circular workpiece to rotate through the frictional force between the welded part and the driving roller, thereby completing the welding of the circumferential weld. The roller stand plays a crucial role in the welding process, which can improve the weld quality, reduce the labor intensity, and improve the work efficiency.

[0003] At present, the distance between the used roller stands is generally fixedly set. When the roller stand is required to support some larger cylindrical workpieces, the contact area between the cylindrical workpiece and the roller stand is small, resulting in the situation that the cylindrical workpiece is prone to fall off when rotating on the top of the roller stand. Summary of the Invention

[0004] The purpose of the present invention is to provide an adjustable roller stand to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0009] Further, the two limiting blocks are symmetrically arranged with the screw hole disc as the center. One end of the two limiting blocks away from the screw hole disc is slidably connected to the inner wall of the chute frame. The end of the roller is fixedly connected to the output end of the power device, and the roller frame is located above the chute frame.

[0010] Further, the supporting member includes a fixing rod. One end of the fixing rod is fixedly connected to the surface of the roller frame. One end of the fixing rod away from the roller frame is fixedly connected with a cylindrical rod. One end of the cylindrical rod is fixedly connected with a bent frame. One end of the bent frame away from the cylindrical rod is fixedly connected with an elastic rod. One end of the elastic rod away from the bent frame is hinged with a triangular frame. The top of the triangular frame is hinged with a contact frame. The top of the contact frame is fixedly connected with a semi-circular frame. A cylindrical groove is opened at the bottom of the inner wall of the semi-circular frame. A rotating rod is rotatably connected to the inner wall of the cylindrical groove. A sliding hole frame is fixedly connected to the surface of the contact frame. A sliding rod is fixedly connected to the top of the bottom frame. When the distance between the roller frames is adjusted to the maximum, the top of the contact frame is located at the lower surface of the roller. When the cylindrical workpiece is placed on the surface of the roller, the bottom of the cylindrical workpiece can contact the bottom of the inner wall of the semi-circular frame.

[0011] Further, the number of the contact frames is two. The two contact frames are symmetrically arranged with the roller frame as the center. One end of the bent frame close to the elastic rod extends below the cylindrical rod. The fixing rod is located on the lower surface of the roller frame.

[0012] Further, the inner wall of the sliding hole frame is slidably connected to the surface of the sliding rod.

The number of the inclined surface arc plates is two. The two inclined surface arc plates are symmetrically arranged with the bottom frame as the center. The tops of the two inclined surface arc plates are arranged to be away from each other.

[0015] The present invention has the following beneficial effects:

[0016] When the spacing between the rollers of the present invention needs to be adjusted, the motor is started to drive the threaded rod to rotate inside the circular hole frame. The threaded hole disc slides inside the chute frame through the limiting block, and the chute frame and the limiting block are used to limit the threaded hole disc in contact. At this time, the threaded hole disc can push the support plate to move through the rotation of the threaded rod. The support plate drives the roller frame to move closer to each other as the threaded hole disc is pushed, so as to adjust the spacing between the rollers, so that the roller frame can support and limit cylindrical workpieces of different sizes. The threaded hole disc slides inside the chute frame through the limiting block, and the limiting block supports the threaded hole disc to avoid the large force on the threaded rod affecting the adjustment of the roller frame. The power device is started to drive the rollers to rotate inside the roller frame, and the rollers drive the cylindrical workpiece to rotate through friction, improving the convenience of the cylindrical workpiece during welding.

[0017] When the roller frames of the present invention move closer to each other, the fixed rod drives the cylindrical rod to move. When the cylindrical rod moves, it pushes the bottom of the triangular frame to contract through the connection of the bent frame and the elastic rod. When the bottom of the triangular frame contracts, it pushes the contact frame at the top to move upward. When the contact frame moves, it pushes the rotating rod inside the semi-circular frame to contact the bottom of the cylindrical workpiece, so as to support and limit the cylindrical workpiece by using the semi-circular frame, improving the stability of the cylindrical workpiece during welding operations. The smaller the spacing between the roller frames, the greater the squeezing force of the contact frame on the cylindrical workpiece, playing a role in supporting the cylindrical workpiece and improving the stability of the cylindrical workpiece during rotation. When the roller frames move away from each other, the contact frame will push the contact frame to contact the cylindrical workpiece through the elasticity of the elastic rod to support and limit it.

[0018] When the cylindrical workpiece is placed on the surface of the rollers of the present invention, the cylindrical workpiece contacts the upper surface of the inclined arc-shaped plate and uses gravity to push the inclined arc-shaped plate to move away from each other. When the lower surface of the cylindrical workpiece contacts the upper surface of the rollers, the surface of the cylindrical workpiece will contact the stabilizing rod. The inclined arc-shaped plate and the stabilizing rod cooperate with each other to limit the cylindrical workpiece, avoiding the situation of the cylindrical workpiece falling off during rotational processing.

[0019] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on 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 protection scope of the present invention.

[0032] The roller component 2 includes a round hole frame 15. The bottom of the round hole frame 15 is fixedly connected to the top of the bottom frame 1. A threaded rod 19 is rotatably connected to the inner wall of the round hole frame 15. The end of the threaded rod 19 is fixedly connected to a motor 18. The surface of the motor 18 is fixedly connected to a bracket 17. The lower surface of the bracket 17 is fixedly connected to the surface of the bottom frame 1. A threaded hole plate 14 is threadedly connected to the surface of the threaded rod 19. When the present invention needs to adjust the spacing of the rollers 11, the motor 18 is started to drive the threaded rod 19 to rotate inside the round hole frame 15. The threaded hole plate 14 slides inside the chute frame 16 through a limit block 20. The contact between the chute frame 16 and the limit block 20 is used to limit the threaded hole plate 14. At this time, the threaded hole plate 14 can push the support plate 13 to move through the rotation of the threaded rod 19. The top of the bottom frame 1 is fixedly connected to a chute frame 16. The surface of the threaded hole plate 14 is fixedly connected to a limit block 20. The top of the threaded hole plate 14 is fixedly connected to a support plate 13. The top of the support plate 13 is fixedly connected to a roller frame 10. The inner wall of the roller frame 10 is rotatably connected to a roller 11. The support plate 13 moves closer to each other along with the threaded hole plate 14 pushing the roller frame 10, thereby adjusting the spacing of the rollers 11 so that the roller frame 10 can support and limit cylindrical workpieces of different sizes. The threaded hole plate 14 slides inside the chute frame 16 through the limit block 20. The end of the roller frame 10 is fixedly connected to a power device 12. A support component 3 is arranged on the surface of the roller frame 10. A stabilizing component 4 is arranged above the bottom frame 1.

[0033] The number of the round hole frames 15 is set to two. The two round hole frames 15 are symmetrically arranged with the bottom frame 1 as the center. The end of the threaded rod 19 extends to the outer end of the round hole frame 15. The number of the limit blocks 20 is set to four. The four limit blocks 20 are set into two groups, and the number of each group of limit blocks 20 is set to two.

[0034] The two limit blocks 20 are symmetrically arranged with the threaded hole plate 14 as the center. One end of the two limit blocks 20 away from the threaded hole plate 14 is slidably connected to the inner wall of the chute frame 16. The threaded hole plate 14 is supported by the limit blocks 20 to prevent the threaded rod 19 from being affected by large forces and affecting the adjustment of the roller frame 10. The power device 12 is started to drive the rollers 11 to rotate inside the roller frame 10. The rollers 11 drive the cylindrical workpiece to rotate through friction, improving the convenience during the welding of the cylindrical workpiece. The end of the roller 11 is fixedly connected to the output end of the power device 12. The roller frame 10 is located above the chute frame 16.

[0035] The support member 3 includes a fixed rod 30, the end of the fixed rod 30 is fixedly connected to the surface of the roller frame 10, a cylindrical rod 31 is fixedly connected to the end of the fixed rod 30 away from the roller frame 10, a bent frame 33 is fixedly connected to the end of the cylindrical rod 31, and an elastic rod 32 is fixedly connected to the end of the bent frame 33 away from the cylindrical rod 31. When the roller frames 10 of the present invention move closer to each other, the fixed rod 30 drives the cylindrical rod 31 to move. When the cylindrical rod 31 moves, the connection between the bent frame 33 and the elastic rod 32 pushes the bottom of the triangular frame 39 to contract. When the bottom of the triangular frame 39 contracts, it pushes the contact frame 35 at the top to move upward. One end of the elastic rod 32 away from the bent frame 33 is hinged to the triangular frame 39, the top of the triangular frame 39 is hinged to the contact frame 35, the top of the contact frame 35 is fixedly connected to a semi-circular frame 34, a cylindrical groove 37 is opened at the bottom of the inner wall of the semi-circular frame 34, and a rotating rod 36 is rotatably connected to the inner wall of the cylindrical groove 37. When the contact frame 35 moves, it pushes the rotating rod 36 inside the semi-circular frame 34 to contact the bottom of the cylindrical workpiece, so as to support and limit the cylindrical workpiece by using the semi-circular frame 34, improving the stability of the cylindrical workpiece during the welding operation. The smaller the distance between the roller frames 10, the greater the squeezing force of the contact frame 35 on the cylindrical workpiece, playing a role in supporting the cylindrical workpiece and improving the stability of the cylindrical workpiece during rotation. A sliding hole frame 38 is fixedly connected to the surface of the contact frame 35, and a sliding rod 40 is fixedly connected to the top of the bottom frame 1.

[0036] The number of the contact frames 35 is set to two. When the roller frames 10 move away from each other, the contact frame 35 will be elastically pushed by the elastic rod 32 to contact the cylindrical workpiece and support and limit it. The two contact frames 35 are symmetrically arranged with the roller frame 10 as the center. One end of the bent frame 33 close to the elastic rod 32 extends below the cylindrical rod 31, and the fixed rod 30 is located on the lower surface of the roller frame 10.

[0037] The inner wall of the sliding hole frame 38 is slidably connected to the surface of the sliding rod 40. The upper surface of the rotating rod 36 extends to the outer end of the cylindrical groove 37. The ends of the triangular frame 39 away from the contact frame 35 are arranged to be away from each other.

[0038] The stabilizing member 4 includes a mounting frame 53. The inner wall of the mounting frame 53 is fixedly connected to the surface of the cylindrical rod 31. A positioning rod 54 is fixedly connected to the surface of the mounting frame 53. A elastic rod 55 is fixedly connected to the end of the positioning rod 54 away from the mounting frame 53. When the cylindrical workpiece is placed on the surface of the roller 11 in the present invention, the cylindrical workpiece contacts the upper surface of the inclined surface arc plate 50 and uses gravity to push the inclined surface arc plate 50 to move away from each other. When the lower surface of the cylindrical workpiece contacts the upper surface of the roller 11, one end of the elastic rod 55 away from the positioning rod 54 is fixedly connected to the inclined surface arc plate 50. A groove 51 is opened on the lower surface of the inclined surface arc plate 50, and a stabilizing rod 52 is rotatably connected to the inner wall of the groove 51.

[0039] One end of the positioning rod 54 away from the mounting bracket 53 extends above the roller 11. The groove 51 is located at one end of the inclined surface arc plate 50 away from the elastic rod 55. The surface of the cylindrical workpiece will contact the stabilizing rod 52. The inclined surface arc plate 50 and the stabilizing rod 52 cooperate with each other to limit the cylindrical workpiece, preventing the cylindrical workpiece from falling off during rotational processing. The number of inclined surface arc plates 50 is two, and the two inclined surface arc plates 50 are symmetrically arranged with the chassis 1 as the center. The tops of the two inclined surface arc plates 50 are arranged to be away from each other.

[0040] During use, when it is necessary to adjust the spacing of the rollers 11, start the motor 18 to drive the threaded rod 19 to rotate inside the circular hole frame 15. The threaded hole plate 14 slides inside the chute frame 16 through the limit block 20. The contact between the chute frame 16 and the limit block 20 is used to limit the threaded hole plate 14. At this time, the threaded hole plate 14 can push the support plate 13 to move through the rotation of the threaded rod 19. The support plate 13 drives the roller frame 10 to move closer to each other as the threaded hole plate 14 is pushed, thereby adjusting the spacing of the rollers 11 so that the roller frame 10 can support and limit cylindrical workpieces of different sizes. The threaded hole plate 14 slides inside the chute frame 16 through the limit block 20, and the limit block 20 supports the threaded hole plate 14 to prevent the threaded rod 19 from being affected by a large force and affecting the adjustment of the roller frame 10. Start the power device 12 to drive the rollers 11 to rotate inside the roller frame 10. The rollers 11 drive the cylindrical workpiece to rotate through friction, improving the convenience of the cylindrical workpiece during welding. When the roller frames 10 move closer to each other, the fixed rod 30 drives the cylindrical rod 31 to move. When the cylindrical rod 31 moves, it pushes the bottom of the triangular frame 39 to contract through the connection between the bent frame 33 and the elastic rod 32. When the bottom of the triangular frame 39 contracts, it pushes the contact frame 35 at the top to move upward. When the contact frame 35 moves, it pushes the rotating rod 36 inside the semi-circular frame 34 to contact the bottom of the cylindrical workpiece, thereby using the semi-circular frame 34 to support and limit the cylindrical workpiece and improving the stability of the cylindrical workpiece during welding operations. The smaller the spacing between the roller frames 10, the greater the squeezing force of the contact frame 35 on the cylindrical workpiece, playing a role in supporting the cylindrical workpiece and improving the stability of the cylindrical workpiece during rotation. When the roller frames 10 move away from each other, the contact frame 35 will be elastically pushed by the elastic rod 32 to contact the cylindrical workpiece and support and limit it. When the cylindrical workpiece is placed on the surface of the rollers 11, the cylindrical workpiece contacts the upper surface of the inclined surface arc plate 50 and uses gravity to push the inclined surface arc plate 50 to move away from each other. When the lower surface of the cylindrical workpiece contacts the upper surface of the rollers 11, the surface of the cylindrical workpiece will contact the stabilizing rod 52. The inclined surface arc plate 50 and the stabilizing rod 52 cooperate with each other to limit the cylindrical workpiece, preventing the cylindrical workpiece from falling off during rotational processing.
