Description

Technical Field

[0001] This invention relates to the field of precision sheet metal processing technology, and in particular to an auxiliary device for precision sheet metal processing that is easy to operate. Background Technology

[0002] There is still no complete definition for precision sheet metal. According to a definition in a foreign professional journal, it can be defined as follows: Sheet metal is a comprehensive cold working process for thin metal sheets, including shearing, punching / cutting / compound cutting, bending, welding, riveting, splicing, forming, etc. Its significant feature is that the thickness of the same part is consistent. Auxiliary devices are required for auxiliary operation in the sheet metal processing production process.

[0003] In existing technologies, sheet metal processing can only be auxiliaryly clamped on flat sheet metal. This results in poor clamping stability and limited applicability when processing sheet metal with raised or recessed surfaces, easily leading to processing failures. This not only wastes sheet metal materials but also causes quality problems, hindering processing. Therefore, this invention proposes an easy-to-operate auxiliary device for precision sheet metal processing to overcome the shortcomings of existing technologies. Summary of the Invention

[0025] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0026] Example 1:

[0027] according to Figure 1-5 As shown in the figure, this embodiment proposes an auxiliary device for precision sheet metal processing that is easy to operate. It includes a base 1, an angle adjustment mechanism, a position adjustment mechanism, and a clamping device. The angle adjustment mechanism is located above the base 1, a mounting plate 2 is located above the angle adjustment mechanism, a position adjustment mechanism is located above the mounting plate 2, and a first clamping worktable 3 and a second clamping worktable 4 are located above the position adjustment mechanism. Both the first clamping worktable 3 and the second clamping worktable 4 are equipped with clamping devices. Each clamping device includes a limiting plate 5 and a movable clamping mechanism, which are symmetrically arranged. The movable clamping mechanism includes a first linear movement component, a base 6, a first mounting base 7, a second mounting base 8, a first clamping arm assembly 9, and a second clamping arm. The base 6 has a side wall connected to a first linear motion assembly, and a first mounting seat 7 and a second mounting seat 8 on the other side wall of the base 6. A first rotating seat 12 is provided on the base 6 on one side of the first mounting seat 7, and a second rotating seat 13 is provided on the base 6 on one side of the second mounting seat 8. A third rotating seat 14 is movably provided inside the first mounting seat 7, and a fourth rotating seat 15 is movably provided inside the second mounting seat 8. The first clamping arm assembly 9 is connected to the first rotating seat 12 and the third rotating seat 14 respectively, the second clamping arm assembly 10 is connected to the third rotating seat 14 and the fourth rotating seat 15 respectively, and the third clamping arm assembly 11 is connected to the fourth rotating seat 15 and the second rotating seat 13 respectively.

[0028] When using the device of the present invention to assist sheet metal processing, when the sheet metal part being processed is a non-flat surface shape, the sheet metal is first placed on the limiting plate, and then the first clamping arm assembly 9, the second clamping arm assembly 10 and the third clamping arm assembly 11 on the base 6 are moved towards the limiting plate 5 by the first linear moving assembly. When a certain position of the sheet metal part protrudes, the clamping arm assembly (any one or two of the first clamping arm assembly 9, the second clamping arm assembly 10 and the third clamping arm assembly 11) at that position is squeezed by the protruding position, causing the first arm 20 and the second arm 21 to rotate, and then the arc-shaped limiting block 18 clamps the sheet metal part.

[0029] Both the first mounting base 7 and the second mounting base 8 are equipped with guide rails 16 inside. The bottom of the third rotating base 14 and the fourth rotating base 15 are provided with guide grooves 17 adapted to the guide rails 16, and the guide grooves 17 are slidably connected to the guide rails 16. The first clamping arm assembly 9, the second clamping arm assembly 10, and the third clamping arm assembly 11 have the same structure, each including an arc-shaped limiting block 18, a fifth rotating base 19, a first support arm 20, and a second support arm 21. The fifth rotating base 19 is provided on one side of the arc-shaped limiting block 18, and one end of the first support arm 20 and the second support arm 21 are connected to the fifth rotating base 19. When the first clamping arm assembly 9, the second clamping arm assembly 10, and the third clamping arm assembly 11 are compressed, the first support arm 20 and the second support arm 21 connected to the third rotating base 14 and the fourth rotating base 15 will move on the guide rails 16 following the third rotating base 14 and the fourth rotating base 15 to complete the limiting clamping of the sheet metal part with the convex surface shape.

[0030] The first linear motion assembly includes a first adjusting seat 22, a first threaded adjusting rod 23, a movable seat 24, and a movable block 25. Movable seats 24 are provided on both sides of the first adjusting seat 22, and movable blocks 25 are symmetrically arranged on the sidewalls of the base 6. The movable blocks 25 are slidably connected to the movable seats 24. The first clamping worktable 3 and the second clamping worktable 4 are both provided with the first adjusting seat 22. The first threaded adjusting rod 23 is threadedly connected to the first adjusting seat 22, and one end of the first threaded adjusting rod 23 is rotatably connected to the sidewall of the base 6. When the first linear motion assembly moves the base 6, the base 6 can be moved by rotating the first threaded adjusting rod 23. To maintain stability and guidance, the movable blocks 25 slide within the movable seats 24.

[0031] The limiting plate 5 is provided with a long through groove 26, and a hydraulic cylinder 27 is provided in the long through groove 26. The output end of the hydraulic cylinder 27 is provided with an elastic limiting piece. A second linear movement assembly is provided on one side wall of the limiting plate 5. The hydraulic cylinder 27 is mounted on the second linear movement assembly. The second linear movement assembly includes a second adjusting seat 28, a second threaded adjusting rod 29, and an L-shaped assembly plate 30. The second adjusting seat 28 is provided on the side wall of the limiting plate 5. The second threaded adjusting rod 29 is threadedly connected to the second adjusting seat 28. The L-shaped assembly plate 30 is rotatably mounted on one end of the second threaded adjusting rod 29. One end of the hydraulic cylinder 27 is mounted on the L-shaped assembly plate 30. One end of the L-shaped assembly plate 30 is slidably connected to the side wall of the limiting plate 5. Rotating the second threaded adjusting rod 29 moves the L-shaped assembly plate 30 to a different position, thereby moving the hydraulic cylinder 27 to a different position. In this invention, when the side wall of the sheet metal part in contact with the limiting plate 5 has a concave shape, in order to improve the fixing stability, the position of the hydraulic cylinder 27 in the long through groove 26 is adjusted by the second linear moving component according to the concave shape, and the hydraulic cylinder 27 is controlled to extend to fix the concave shape, thereby further improving the fixing stability.

[0032] The angle adjustment mechanism includes a rotary motor 31, a drive gear 32, a hollow mounting shaft 33, and a gear disk 34. The hollow mounting shaft 33 is rotatably mounted above the base 1, and the gear disk 34 is mounted on the hollow mounting shaft 33. The mounting plate 2 is mounted on the top of the gear disk 34. The rotary motor 31 is mounted on the base 1, and the drive gear 32 is mounted on the output end of the rotary motor 31. The drive gear 32 meshes with the gear disk 34. The rotation of the rotary motor 31 drives the drive gear 32 to rotate, which in turn drives the meshing gear disk 34 to rotate, and finally causes the mounting plate 2 to rotate accordingly.

[0033] The position adjustment mechanism includes a drive motor 35, a driving bevel gear 36, a driven bevel gear 37, a transmission gear 38, and a rack 39. The drive motor 35 is disposed inside the mounting plate 2. The output end of the drive motor 35 passes through the mounting plate 2 and is provided with the driving bevel gear 36. The mounting plate 2 is provided with a first guide seat 40 and a second guide seat 41. A drive shaft 42 is rotatably mounted on the first guide seat 40 and the second guide seat 41. The drive shaft 42 is provided with the driven bevel gear 37 and the transmission gear 38. A first connecting seat 43 and a second connecting seat 44 are slidably disposed in the first guide seat 40 and the second guide seat 41, respectively. A rack 39 is provided at the bottom of the first connecting seat 43 and the second connecting seat 44. The rack 39 meshes with the transmission gear 38.

[0034] The first clamping worktable 3 is mounted on the first connecting seat 43, and the second clamping worktable 4 is mounted on the second connecting seat 44. Both the first connecting seat 43 and the second connecting seat 44 are provided with sliding grooves 45. One end of the first clamping worktable 3 is slidably connected to the sliding groove 45 on the second connecting seat 44, and one end of the second clamping worktable 4 is slidably connected to the sliding groove 45 on the first connecting seat 43. When the drive motor 35 rotates, it drives the active bevel gear 36 to rotate, thereby driving the driven bevel gears 37 meshing on both sides to rotate relative to each other. At this time, the transmission gear 38 on the drive shaft 42 rotates accordingly, driving the rack 39 to move, and then driving the first connecting seat 43 and the second connecting seat 44 to move.

The two ends of the base 6 are slidably connected to the limiting grooves 46. By setting the limiting grooves 46, the movement stability of the base 6 can be improved.
