Automatic assembling mechanism for automobile safety belt locking ratchet wheel

Abstract

The invention discloses an automatic assembling mechanism for an automobile safety belt locking ratchet wheel, and relates to the technical field of automobile safety belt retractors. A discharge port of a ratchet wheel material bin is arranged above a ratchet wheel vibration disc. The discharge end of the ratchet wheel vibration disc is provided with a ratchet wheel transferring and carrying mechanical arm. A discharge port of a pawl material bin is arranged above a pawl vibration disc. The discharge end of the pawl vibration disc is provided with a pawl grabbing mechanical arm and a downwards-pressing mechanism. A discharge mechanism comprises a grabbing mechanical arm and a discharge assembly line. A rotating mechanism comprises a four-station rotating disc. A work position is formed each time the four-station rotating disc rotates by 45 degrees, and cycle operation is achieved. The automatic assembling mechanism is high in reliability, capable of achieving full-automatic assembling of a locking ratchet wheel assembly, improving the production efficiency, decreasing the rejection rate and reducing the production cost, high in precision, accurate in positioning and high in practicability.

Description

technical field [0001] The invention relates to the technical field of an automobile safety belt retractor, in particular to an automatic assembly mechanism for an automobile safety belt locking ratchet. Background technique [0002] The locking mechanism is an important part of the emergency locking car seat belt retractor. It includes a ratchet and a pawl mechanism. The ratchet and the reel are integrated into one body. The change rate sensitive device senses that the speed change rate of the vehicle exceeds the specified value, immediately controls the engagement of the ratchet and pawl, prevents the reel drum from rotating, and locks the ribbon. Therefore, the locking ratchet is an important part to realize the action of the retractor, and it also determines Whether the function of the car seat belt can be realized. [0003] The locking ratchet assembly is divided into a ratchet and a pawl, and there is an assembly relationship between the two. In the past, we usually u...

AI Technical Summary

Problems solved by technology

[0003] The locking ratchet assembly is divided into a ratchet and a pawl, and there is an assembly relationship between the two. In the past, we usually used manual assembly to force the pawl into the positioning shaft of the ratchet to complete the assembly, but the production efficiency was low and the workers were laborious. High strength, prone to many problems such as defective products

However, when using machine assembly, since the pawl needs to be installed inside the ratchet, it cannot be directly pushed, so it is very difficult to realize fully automatic assembly.
