Description

Technical Field

[0001] This utility model belongs to the field of displacement device technology, specifically relating to an L-shaped flip displacement device. Background Technology

[0002] In related technologies, when welding ring-shaped or tubular workpieces, a positioner is needed to clamp and fix the workpiece so that the welding mechanism can perform welding processing on the workpiece.

[0003] Existing technology (authorization announcement number: CN206795141U) discloses a welding positioner, including: a rotating shaft; a bearing; a turntable disposed on the rotating shaft and capable of rotating with the rotating shaft; multiple clamping devices arranged circumferentially on the turntable; a drive device for driving the rotating shaft to rotate or stop; a frame, with the rotating shaft passing through the frame; and welding equipment connected to the frame. In this invention, the turntable can rotate or stop with the rotating shaft, and multiple clamping devices are disposed on the turntable, each clamping device for clamping one workpiece to be welded. While the welding equipment is welding one workpiece, the operator can clamp another workpiece, thus achieving simultaneous welding and clamping operations, greatly improving welding efficiency. Furthermore, because the turntable is rotatable, the weld seam on the workpiece can rotate with the turntable to the ideal position before welding, thus avoiding welding dead angles and improving welding quality.

[0004] In this prior art, the turntable can only rotate the workpiece, but cannot rotate it, which makes it inconvenient for the welding mechanism to weld the inner or outer wall of the workpiece. Utility Model Content

[0012] In the above technical solution, the L-shaped flipping and repositioning device further includes: a connecting groove; the connecting groove is elongated and is located inside the pressure plate, and the screw passes through the connecting groove.

[0013] In the above technical solution, the L-shaped tilting and repositioning device further includes: a front baffle, a rear baffle, a cover plate, and a clearance groove; the two ends of the front baffle are respectively connected to the front walls of the two support frames; the two ends of the rear baffle are respectively connected to the rear walls of the two support frames; the two ends of the cover plate are respectively connected to the tops of the two support frames; the clearance groove is set inside the cover plate and is arranged around the outside of the drive box.

[0014] The L-shaped flipping and repositioning device of this utility model has the following advantages compared with the prior art:

[0015] 1. By connecting one end of the spindle to the worktable, allowing the spindle to pass through the top of the drive box, and rotatably connecting the other end of the spindle to the drive box, the drive box supports the worktable via the spindle. This allows the worktable to rotate relative to the drive box, thereby rotating the workpiece fixed on the worktable, facilitating welding at different positions on the workpiece by the welding mechanism. By connecting two rotating shafts to both sides of the drive box and rotatably connecting each shaft to a support frame, the two support frames support the drive box via the two rotating shafts. This allows the drive box to rotate between the two support frames, enabling the workpiece fixed on the worktable to flip, facilitating welding of the inner or outer wall of the workpiece by the welding mechanism.

[0016] 2. Since the first gear meshes with the second gear, the rotation angle of the worktable can be precisely controlled when the first drive device drives the first gear to rotate.

[0017] 3. By installing the first protective cover on the top of the drive housing and wrapping it around the outside of the first gear, the drive housing can support the first protective cover, thereby protecting the first gear and improving its quality; by installing the second protective cover on the top of the drive housing and wrapping it around the outside of the second gear, the drive housing can support the second protective cover, thereby protecting the second gear and improving its quality.

[0018] 4. By mounting the second drive unit on the outside of a support frame and connecting the second output shaft of the second drive unit to a rotating shaft, the support frame supports the second drive unit, thereby enabling the second drive unit to drive the rotating shaft to rotate and thus provide power to the rotating drive box.

[0019] 5. By mounting the positioning disc on the outside of a rotating shaft and installing the positioning block at the bottom of the positioning disc, the rotating shaft can drive the positioning disc and positioning block to rotate. By mounting the cylinder on the inner wall of a support frame and having the cylinder shaft fit against the positioning block, the support frame can support the cylinder, thereby enabling the cylinder to drive the cylinder shaft to fit against the positioning block, thus preventing the positioning block, positioning disc, and rotating shaft from rotating. This ensures that the worktable is in a horizontal state, thereby improving the stability of the workpiece placed on the worktable.

[0020] 6. By setting a long strip-shaped connecting groove inside the pressure plate and allowing the screw to pass through the connecting groove, the screw can move within the connecting groove, thereby adjusting the relative position between the screw and the pressure plate. This ensures that the pressure plate can press the workpiece placed on the worktable, thus improving the user experience of the product.

[0021] 7. By setting the clearance groove inside the cover plate and making the clearance groove surround the outer groove of the drive box, the drive box can be flipped within the clearance groove, thereby avoiding interference between the drive box and the cover plate and improving the user experience of the product.

Detailed Implementation

[0030] The following are specific implementation cases and appendices. Figures 1 to 6 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0031] An L-shaped flipping and repositioning device, such as Figures 1 to 6 As shown, the L-shaped flipping and repositioning device includes: a base plate 10, a support frame 11, a drive box 12, a rotating shaft 13, a worktable 14, a main shaft 15, a mounting groove 16, a screw 17, a pressure plate 18, and a fixing nut 19; two support frames 11 are mounted on the base plate 10, and there is a gap between the two support frames 11; the drive box 12 is a hollow cavity, and the drive box 12 is located between the two support frames 11; two rotating shafts 13 are respectively connected to both sides of the drive box 12, and the two rotating shafts 13 are respectively rotatably connected to the two support frames 11; the worktable 14 is located above the drive box 12; one end of the main shaft 15 is connected to the worktable 14, and the main shaft 15 passes through... The top of the drive box 12 is connected to the other end of the spindle 15, which is rotatably connected to the drive box 12. The mounting slot 16 is T-shaped, and at least two mounting slots 16 are set on the top of the worktable 14 and are evenly distributed along the center line of the worktable 14. The outer wall of the screw 17 is provided with external threads, and at least two screws 17 are respectively embedded in at least two mounting slots 16. At least two pressure plates 18 are respectively fitted on the outside of at least two screws 17. The fixing nut 19 is provided with internal threads, and the fixing nut 19 is fitted on the outside of the screw 17 and is in contact with the top of the pressure plate 18. The external threads and internal threads are matched.

[0032] By mounting two support frames 11 on the base plate 10, connecting two rotating shafts 13 to the two sides of the drive box 12 respectively, and rotatably connecting the two rotating shafts 13 to the two support frames 11 respectively, the base plate 10 supports the two support frames 11, thereby enabling the two support frames 11 to support the drive box 12 through the two rotating shafts 13, and thus enabling the drive box 12 to rotate between the two support frames 11; by connecting one end of the spindle 15 to the worktable 14, allowing the spindle 15 to pass through the top of the drive box 12, and rotatably connecting the other end of the spindle 15 to the drive box 12, the drive box 12 supports the worktable 14 through the spindle 15, thereby enabling the worktable 14 to rotate relative to the drive box 12. By setting multiple T-shaped mounting slots 16 on the top of the worktable 14 and embedding multiple screws 17 into the mounting slots 16 respectively, the screws 17 can move within the mounting slots 16 while preventing them from moving out of the mounting slots 16 along the axial direction of the worktable 14. By fitting a pressure plate 18 around the outside of the screws 17 and a fixing nut 19 around the outside of the screws 17, with the fixing nut 19 abutting against the top of the pressure plate 18, the pressure plate 18 can abut against the top of the workpiece when it is placed on the worktable 14. This allows the workpiece to be pressed firmly onto the worktable 14 using the fixing nut 19 and the pressure plate 18, improving the stability of the workpiece and facilitating subsequent welding processing.

[0033] When using the product, first rotate the drive box 12 and the worktable 14 to make the worktable 14 horizontal; then, place the workpiece to be welded on the worktable 14; next, move the screw 17 in the mounting slot 16 so that multiple pressure plates 18 simultaneously come into contact with the top of the workpiece; then, tighten the fixing nut 19 so that the fixing nut 19 fits tightly with the pressure plate 18, so that the pressure plate 18 presses the workpiece firmly on the worktable 14; then, use the welding mechanism to weld the workpiece; when preparing to adjust the welding position of the workpiece, rotate the worktable 14 so that the worktable 14 drives the workpiece to rotate, so that the welding mechanism can weld different positions of the workpiece; when preparing to weld the outer or inner wall of the workpiece, rotate the drive box 12 so that the drive box 12 drives the worktable 14 and the workpiece to rotate, so that the welding mechanism can weld the inner or outer wall of the workpiece.

[0034] With the above structure, by connecting one end of the spindle 15 to the worktable 14, allowing the spindle 15 to pass through the top of the drive box 12, and rotatably connecting the other end of the spindle 15 to the drive box 12, the drive box 12 supports the worktable 14 via the spindle 15. This allows the worktable 14 to rotate relative to the drive box 12, thereby rotating the workpiece fixed on the worktable 14, facilitating welding at different positions of the workpiece by the welding mechanism. By connecting two rotating shafts 13 to both sides of the drive box 12, and rotatably connecting the two rotating shafts 13 to two support frames 11, the two support frames 11 support the drive box 12 via the two rotating shafts 13. This allows the drive box 12 to rotate between the two support frames 11, enabling the workpiece fixed on the worktable 14 to flip, facilitating welding of the inner or outer wall of the workpiece by the welding mechanism.

By connecting the second gear 22 to the bottom of the worktable 14 and meshing the second gear 22 with the first gear 21, when the first drive unit 20 drives the first gear 21 to rotate, the first gear 21 can mesh with the second gear 22 to rotate, thereby driving the worktable 14 and the workpiece fixed on the worktable 14 to rotate. Since the first gear 21 and the second gear 22 mesh, when the first drive unit 20 drives the first gear 21 to rotate, the rotation angle of the worktable 14 can be precisely controlled.

By mounting a third protective cover 26 on the outside of a support frame 11 and surrounding the second drive unit 25, the support frame 11 supports the third protective cover 26, thus protecting the second drive unit 25 from damage due to external forces and improving the overall quality of the second drive unit 25.
