Technical Field
[0001] This utility model relates to the field of precision metal sheet metal structural parts processing technology, and in particular to an assembly fixture for processing miniature precision metal sheet metal structural parts. Background Technology

[0015] Preferably, the base suction cup and the auxiliary suction cup have the same structure. The base suction cup includes a vacuum suction cup fixedly mounted on the top of the slider and a vacuum pump located at the bottom of the assembly table.

Detailed Implementation
[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0032] like Figures 1 to 4 As shown, an assembly fixture for processing miniature precision sheet metal structural parts includes an assembly table 1 and a toothed rotating ring 4 rotatably disposed on the assembly table 1.
[0033] Two support columns 6 are fixed relative to each other on the toothed rotating ring 4. The top of the assembly table 1 is circular, and the assembly table 1 and the toothed rotating ring 4 are concentric circles. The lines connecting the centers of the two support columns 6 and the assembly table 1 are perpendicular to each other, so that the distance between them is large enough and close enough to the boundary of the assembly table 1. In this way, without affecting the horizontal fixing of one high-precision metal sheet metal part on the assembly table 1, another high-precision metal sheet metal part can be fixed between the two support columns 6.
[0034] A drive component 5 is used to drive the toothed ring 4 to rotate. The drive component 5 includes a motor frame 53 fixed at the edge of the assembly table 1. A drive motor 54 is fixedly mounted on the motor frame 53. A gear 55 is fixedly mounted on the output end of the drive motor 54. An annular groove 51 is provided on the top of the assembly table 1. The toothed ring 4 is rotatably fitted inside the annular groove 51. A through groove 52 is provided between the annular groove 51 and the outside of the assembly table 1. One side of the gear 55 passes through the inner wall of the through groove 52 and meshes with the tooth surface of the toothed ring 4, so that the drive motor 54 can drive the toothed ring 4 to rotate and drive the support column 6 to rotate synchronously in the circumferential direction.
[0035] An irregularly shaped rod 8 is positioned between two support columns 6, and several auxiliary suction cups 10 are evenly distributed on the rod 8. Through the cooperation of the auxiliary suction cups 10, high-precision metal sheet parts with complex geometric shapes can be fixed by negative pressure adsorption, ensuring that the part to be installed faces downwards. The circumferentially moving support columns 6 drive the irregularly shaped rod 8 and the high-precision metal sheet parts fixed on it to move synchronously, adjusting their circumferential position to facilitate precise docking with the installation part on the high-precision metal sheet parts horizontally fixed on the top of the assembly table 1. In this way, no manual support and fixation are required when assembling two high-precision metal sheet parts, and the stability of the high-precision metal sheet parts is improved.
[0036] An adjustment part 7 is located between one end of the irregular rod 8 and the support column 6. It is used to adjust the position of the irregular rod 8 in the lateral direction and can simultaneously drive the high-precision metal sheet parts that are adsorbed and fixed by the auxiliary suction cup 10 to move.
[0037] An adjusting component 9 is provided at one end of the irregular rod 8, which is used to adjust the angle between the irregular rod 8 and the horizontal, so as to realize the synchronous adjustment of the tilt angle of the high-precision metal sheet metal parts fixed on the irregular rod 8.
[0038] Several base suction cups 2 are set on the assembly table 1 to horizontally fix the high-precision metal plates that serve as the assembly base.
[0039] The drive unit 3, located on the assembly table 1, is used to simultaneously drive several base suction cups 2 to move closer to or further away from the midpoint of the assembly table 1, so as to adjust the coverage area between the base suction cups 2 to match the high-precision metal sheet metal parts that serve as the mounting base, so as to fix them at multiple points and improve the fixing effect.
[0040] Through the cooperation of the adjustment unit 7, adjustment component 9, toothed rotating ring 4 and drive unit 3, one high-precision metal sheet metal part can be assisted in fixing to any designated position on another high-precision metal sheet metal part that is horizontally fixed on the assembly table 1. Furthermore, it can be flexibly adjusted according to the installation tilt angle of different high-precision metal sheet metal parts. In this way, it can assist in the positioning and fixing of various high-precision metal sheet metal parts in the assembly of high-precision metal sheet metal structural parts, without the need for manual support and fixing, and improve the stability of assisted positioning and fixing.
[0041] like Figure 5As shown, the drive unit 3 includes several guide grooves 31 circumferentially disposed on the top of the assembly table 1. A guide rod 32 is radially fixed inside the guide groove 31. A slider 33 is slidably inserted outside the guide rod 32. A base suction cup 2 is fixedly disposed on the top of the slider 33. A vertical telescopic cylinder 34 is fixedly disposed at the bottom of the assembly table 1. A connecting arm 35 is hinged between the output end of the vertical telescopic cylinder 34 and the bottom of the slider 33, so that the vertical telescopic cylinder 34 synchronously drives several sliders 33 and the base suction cup 2 to synchronously approach or move away from the midpoint of the assembly table 1.
[0042] The base suction cup 2 and the auxiliary suction cup 10 have the same structure. The base suction cup 2 includes a vacuum suction cup fixedly mounted on the top of the slider 33 and a vacuum pump located at the bottom of the assembly table 1. A multi-pass pipe is fixedly provided between the suction end of the vacuum pump and the interior of several vacuum suction cups.
[0043] By manipulating the extension or retraction of the vertical telescopic cylinder 34, its output end is used to synchronously push several sliders 33 and vacuum suction cups toward or away from the midpoint of the assembly table 1 along the radial direction of the assembly table 1 via the connecting arm 35. This ensures that the coverage area of the combined vacuum suction cups is smaller than the coverage area of the high-precision metal sheet metal part to be horizontally fixed, so that as many vacuum suction cups as possible can adsorb and fix the high-precision metal sheet metal part, thereby improving the adsorption and fixing effect and being applicable to high-precision metal sheet metal parts with different geometric shapes.
[0044] like Figures 1 to 4 As shown, the adjustment unit 7 includes a rocker arm 71 hinged to the top of the support column 6 and a slide groove 72 on the rocker arm 71. An extension arm 73 is slidably provided in the slide groove 72. The irregular rod 8 and the two extension arms 73 together form a U-shaped support frame. A side telescopic cylinder 74 is fixedly provided on the outside of the rocker arm 71. The output end of the side telescopic cylinder 74 is fixedly provided on the outside of the extension arm 73. The bottom end of the extension arm 73 is hinged to one end of the irregular rod 8. With this design, by controlling the side telescopic cylinder 74 to extend or shorten and synchronously driving the extension arm 73 to extend or shorten, and manually pushing the rocker arm 71 to deflect towards the midpoint of the assembly table 1, and cooperating with the drive component 5 to drive the toothed rotating ring 4 to rotate circumferentially, the position of the high-density metal sheet metal part fixed on the irregular rod 8 can be adjusted in the radial and circumferential directions of the assembly table 1, so that it can be accurately and stably placed on the designated position on the horizontally fixed high-precision metal sheet metal part on the assembly table 1, thereby improving the stability of subsequent assembly operations.
[0045] like Figure 4As shown, the adjusting component 9 includes a limiting sleeve 91 fixed to the bottom of the extension arm 73. A linkage tooth 92 is coaxially fixed to the hinge shaft of one end of the irregular rod 8. A rack 93 is slidably arranged between the inside of the limiting sleeve 91 and the outside of the linkage tooth 92. The tooth surface of the rack 93 meshes with the tooth surface of the linkage tooth 92. A horizontal telescopic cylinder 94 for driving the rack 93 to move axially is fixed on the limiting sleeve 91. With this design, the rack 93 is pushed to move linearly by the horizontal telescopic cylinder 94, thereby driving the linkage tooth 92 to rotate and driving the irregular rod 8 to rotate synchronously. By controlling the extension or retraction of the horizontal telescopic cylinder 94, the driving linkage is achieved. The deflection direction and degree of the tooth 92 drive the shaped rod 8 to deflect synchronously, thereby adjusting the size between the high-precision metal sheet fixed on the shaped rod 8 and the high-precision metal sheet fixed on the assembly table 1. In conjunction with the circumferential rotation position adjustment of the tooth surface ring 4 driven by the drive component 5 and the radial movement position adjustment of the shaped rod 8 driven by the adjustment unit 7, the high-precision metal sheet fixed on the shaped rod 8 is pushed to the designated position efficiently and accurately, and stably supported in the designated position, so that the assembly personnel can perform the assembly operation without manual grasping and support, thus improving the stability of the high-precision metal sheet during the assembly process.
