Automatic turnover device and automatic twisting and cutting machine using same

Abstract

An automatic turnover device is characterized by comprising a turnover fixture. The overturning clamp is installed on a working table (the working table can be a chain plate of a movable transmission chain (11) or a fixed working table plate and the like). The overturning clamp is composed of a bent plate (1), a guide shaft (2), a limiting table (3), a rotating frame (4) and a connecting plate (5). The bending plate (1) of the turning fixture is one of important elements for turning a workpiece, and the shape of the bending plate (1) can be an L shape, a T shape, a mixed shape and the like according to different structures of the workpiece. The guide shaft (2) of the turning fixture is a guide-in element of a workpiece, and the shape of the guide shaft can be round, square, flat, groove-shaped, tooth-shaped and the like according to different structures of the workpiece. A rotating shaft is arranged between two side plates of the rotating frame (4) of the overturning clamp, and the rotating frame (4) is one of important elements for achieving overturning of the workpiece.

Description

Technical Field

[0001] The present invention relates to the technical field of automatic flipping, twisting, cutting, and feeding in industrial automation, and provides an automatic flipping device and an automatic twisting and cutting machine using the same. Specifically, it relates to an automatic flipping device and an automatic twisting and cutting machine using the same. Background Art

[0002] In the manufacturing of electronic appliances, some workpieces (or objects to be processed) need to twist loose materials (such as multi-strand wire ends) tightly, straighten them, or round them, some workpieces (or objects to be processed) need to cut off excess materials (such as multi-strand wire ends), and some workpieces (or objects to be processed) need to be pushed or hung into the next process. For a long time, manual labor has been used to twist the workpieces, cut the workpieces, and place or hang the workpieces into the next process. Manual operation has high labor intensity, poor working environment, and low production efficiency. Summary of the Invention

[0003] Place the workpiece (or object to be processed) on the guide shaft of the flipping fixture. The workpiece is clamped into the limiting platform to position the workpiece. The limiting platform is fixed on the bending plate, and the bending plate is fixed on one side plate of the rotating frame. The other side plate of the rotating frame is fixed on the connecting plate. The flipping fixture consists of (1) bending plate, (2) guide shaft, (3) limiting platform, (4) rotating frame, and (5) connecting plate. The connecting plate of the flipping fixture is installed on the workbench (the workbench can be the chain plate of the moving (11) transmission chain or a fixed workbench plate, etc.). After the workpiece completes the twisting by the (9) twisting device and the cutting by the (10) cutting device on the workbench, it enters the flipping area. The flipping plate pushes the bending plate, and the bending plate rotates along the axis of the rotating frame to the required angle, so that the workpiece completes the flipping at the required angle. The flipping frame consists of (6) flipping plate and (7) telescopic device. The pushing claw pushes the workpiece to the next process (such as a hanging rack). The pushing frame consists of (8) pushing claw and (7) telescopic device. Description of the Drawings

Figure 3 It is a drawing of the flipping frame and the pushing frame for the embodiment. Figure 4 It is a drawing of the automatic twisting and cutting machine for the embodiment. Reference Numerals: (1) bending plate, (2) guide shaft, (3) limiting platform, (4) rotating frame, (5) connecting plate, (6) flipping plate, (7) telescopic device, (8) pushing claw, (9) twisting device, (10) cutting device, (11) transmission chain. Detailed Description

[0005] An automatic twisting and cutting machine applies the above automatic flipping device. The automatic twisting and cutting machine is used for, but not limited to, operations of automatic wire twisting, wire cutting, flipping, pushing, etc. of a frequency conversion transformer. The flipping angle is 1° to 180°. The number of workpieces flipped each time is 1, 2, 3...
