Riveting machine for riveting of circuit boards

Abstract

The invention discloses a riveting machine for riveting of circuit boards. The riveting machine structurally comprises a base, a supporting column, a clamping device, a riveting head, an air cylinder,a machine body, a protective cover and an electric control box. When the riveting machine is used after improvement, a clamping cavity and a pulling piece can be expanded outwards under the extrusionforce of a circuit board, then the position of the clamping cavity is limited by a limiting block, the opening angle of the clamping cavity is prevented from being too large, and the circuit board can be stably clamped on a clamping arm; and when the riveting head impacts a rivet on the circuit board, the clamping arm can shake due to the impact force, a movable elastic rod and a buffer piece arematched with each other to eliminate the shaking force generated by the clamping arm in the riveting process, the riveting head can stably rivet the rivet on the circuit board, it is guaranteed thatthe rivet can be stably and accurately riveted on a riveting hole of the circuit board, the rivet and the circuit board can be stably riveted together, and the riveting efficiency of the circuit boardis improved.

Description

technical field [0001] The invention relates to the field of automatic special machines, in particular to a riveting machine used for riveting circuit boards. Background technique [0002] Riveting machine is also called spin riveting machine, riveting machine, rolling riveting machine, etc. It is a new type of automatic riveting equipment developed based on the principle of cold rolling. For rivet riveting, the common ones are pneumatic, hydraulic and electric. When the rivet is nailed to the circuit board, the circuit board is fixed at the operating position through the fixing element, so that the rivet can be riveted on the circuit board stably. , when riveting the circuit board, the areas that need to be improved: [0003] When riveting the circuit board, due to the large vibration generated during the operation of the equipment, the staff did not fix the circuit board, and the circuit board will have a strong sense of vibration without the action of external force fixi...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies existing in the prior art, the object of the present invention is to provide a riveting machine for riveting circuit boards, so as to solve the problem that when the circuit boards are riveted, there will be a large vibration during the operation of the equipment, and the staff will not check the circuit boards. The board is fixed, and the circuit board will have a strong sense of vibration without the action of external force. The riveting head drives the rivet to be riveted quickly on the riveting hole. Deviations will affect the riveting accuracy of the rivet, and the rivet will be riveted on the edge of the riveting hole, making the diameter inside the riveting hole larger, making the rivet riveting unstable after riveting, and the surface of the circuit board around the riveting hole will be due to This movement causes wear and tear, which leads to the problem that the circuit board is prone to breakage during the riveting process
