Chamfering mechanism for spring bolt

The utility model provides a chamfering mechanism for a spring bolt. The chamfering mechanism comprises a clamping block clamping the spring bolt. The clamping block structurally comprises a bottom frame. A telescopic air cylinder is installed at the bottom of the bottom frame. A lower fixing block is installed at the top of the bottom frame. A boss is arranged at the top of the lower fixing block. Second clamping grooves are formed in the two sides of the lower fixing block respectively. An upper fixing block is installed at the top of the lower fixing block in a matched mode. A groove matched with the boss is formed in the lower portion of the upper fixing block. First clamping grooves are formed in the two sides of the upper fixing block respectively. The first clamping grooves and the second clamping grooves are matched to form a through clamping groove. After the upper fixing block and the lower fixing block are matched and clamped, a through hole for the spring bolt to penetrate through is formed in the middle. Chamfering mechanism bodies and a guide mechanism are installed on the two sides of the clamping block oppositely. Blades of the chamfering mechanism bodies are clamped into the through clamping groove. The chamfering mechanism bodies are arranged on the two sides of the clamping block respectively. The two ends of the spring bolt can be chamfered at the same time, the motion stability is good, work is reliable, and the work efficiency is high.
