Abstract

The invention discloses a quick-change clamp self-locking positioning mechanism which comprises a positioning sleeve. A mounting hole is formed in the positioning sleeve in the axial direction of the positioning sleeve, a locking positioning pin is mounted in the mounting hole, a conical surface is arranged on the periphery of the locking positioning pin, and a notch is formed in the positioning sleeve and communicates with the mounting hole. A locking cam is rotationally connected to the notch of the positioning sleeve through a first pin shaft, the rotating face of the locking cam is parallel to the axis of the locking positioning pin, the locking cam is provided with a locking face, the locking face is matched with the conical surface on the locking positioning pin for locking positioning, the first pin shaft is sleeved with a torsion spring, and the torsion spring can abut against the locking cam. After the locking cam rotates, the locking face is in friction fit with the conical surface on the locking positioning pin, locking of the locking positioning pin is achieved through the acting force of the torsion spring on the locking cam, positioning is accurate, locking is firm, the overall structure is simple, installation is convenient, and cost is low.

Description

technical field [0001] The invention relates to the technical field of quick-change fixtures in production lines, in particular to a self-locking positioning mechanism for quick-change fixtures. Background technique [0002] When production lines (especially automated production lines) produce serialized products, under the conditions of production capacity, in order to effectively control costs, they often adopt the production method of multiple products on the same line. Collinear production means that on the premise that the main function of the production line remains unchanged, multiple types of products of the same series can be produced on one production line by quickly replacing some fixture components. The two most important functions of quick-change fixtures are to achieve accurate positioning and fast locking. The existing quick-change positioning and locking methods are mainly divided into automatic type and manual knob type. The automatic type uses cylinders, m...
