Description

Technical Field

[0001] The present invention relates to the field of detection technology, in particular to a riveting machine with a detection mechanism. Background Art

[0002] When manufacturing magnesium alloy forgings, a riveting machine is used to connect the screw and the bushing. The screw is pressed down by a pressing mechanism, so that the lower end of the screw nut presses down on the annular protrusion at the upper end of the bushing (the cross-section of the annular protrusion is an isosceles trapezoid). The annular protrusion squeezes the screw, connecting the screw and the bushing together. To ensure the stability of the connection and that the annular protrusion does not deform after pressing, subsequent testing is required. The existing testing mechanism is to pull the screw and bushing connected together by a pulling mechanism and perform manual inspection. This method is difficult to accurately test the stability of the connection between the screw and bushing, and it is difficult to conduct a comprehensive inspection. In response to the above problems, we propose a riveting machine with a detection mechanism. Summary of the Invention

[0003] In response to the above problems, the present invention proposes a riveting machine with a detection mechanism, in which the bushing is fixed by an elastic chuck, the pressing mechanism presses down the screw so that the screw is inserted into the bushing, and the screw is pushed by an elastic pushing member. The camera detection mechanism detects whether the distance between the screw and the bushing is qualified, and the elastic chuck rotates with the assistance of a guide ring, so that all-round detection can be carried out.

[0004] The present invention provides a riveting machine with a detection mechanism, which comprises a base, an upper end of the base is connected to a bracket, and a pressing mechanism is provided on the bracket.

[0005] The base is rotatably connected to a support plate via a support shaft, a screw fixing part is provided on the support plate, a guide ring is fixed to the bracket, the screw fixing part moves on the surface of the guide ring, the screw fixing part includes a fixed block, an elastic pushing part, and an elastic clamp, the fixed block is fixed to the support plate, the elastic clamp is rotatably connected to the fixed block, the elastic clamp moves on the surface of the guide ring, and the elastic pushing part is provided inside the elastic clamp.

[0006] A guide ring is fixed on the base, and two camera detection mechanisms are circularly sliding on the base. There are three groups of guide rings, which are concentrically arranged. A moving cavity is formed between two adjacent guide rings. The camera detection mechanism moves in an arc in the moving cavity. A connecting plate is rotatably connected to the support shaft, and the connecting plate is rotatably connected to one of the camera detection mechanisms. A pushing mechanism is provided on the base to push the connecting plate to rotate, so that the two camera detection mechanisms slide back and forth in a circular motion.

[0007] The two camera detection mechanisms are connected by a connecting rope mechanism. The camera detection mechanism includes a detection camera, a support frame, and a sliding block. The sliding block is slidably arranged in the moving cavity. The support frame is fixed to the sliding block. The detection camera is connected to the support frame.

The guide wheel mechanism includes a moving column and a rotating wheel. There are two rotating wheels, which are respectively rotated and arranged at the upper and lower ends of the moving column. The rotating wheel moves on the surface of the middle guide rail ring. The connecting rope head is fixed through the moving column in sequence and is fixed to the tail of the connecting rope. The sliding block is connected to the connecting rope.

[0019] Principle of the present invention: When in use, the bushing is placed in the chuck tube 33, the spring 1 35 presses the lifting ring 34 upward, the lifting ring 34 squeezes the chuck tube 33, clamps and fixes the bushing, the clamping claw 28 clamps the screw, the motor 1 29 is started, drives the motor shaft 30 to rotate, drives the gear 1 31 to rotate, drives the gear 2 32 to rotate, drives the electric telescopic rod 26 to rotate, so that the screw rotates to the upper end of the bushing, the electric telescopic rod 26 is started, drives the cross plate 27 to descend, drives the clamping claw 28 and the screw to descend, the screw extends into the bushing, and squeezes the protrusion at the upper end of the bushing, so that the protrusion deforms and squeezes the screw, so that the bushing and the screw are connected together; The clamping jaw 28 loosens the screw, and the clamping jaw 28 moves upward under the drive of the electric telescopic rod 26. The screw tends to rise under the squeezing force of the spring 2 39. If the screw and the bushing are not properly connected, relative displacement occurs between the screw and the bushing.
