Positioning device for chain machining

The invention relates to the field of chain machining, and discloses a positioning device for chain machining, which comprises a base fixed on the ground, a chain link fixing seat and a chain link moving positioning piece are respectively mounted on two sides of the upper end of the base, and chain link positioning frames are fixedly arranged on opposite sides of the chain link fixing seat and the chain link moving positioning piece; a chain link is fixedly clamped between the opposite chain link positioning frames, the side face of the chain link fixing base is fixedly connected with an installation plate, and a chain link crosspiece positioning assembly is installed on the installation plate. Compared with the prior art, accurate installation of the crosspieces can be achieved, the crosspieces are prevented from inclining, the installation strength of the crosspieces is improved, and the overall structural strength and stability of the chain links are improved. 本发明涉及链条加工领域，公开了一种链条加工用的定位装置，包括固定在地面上的底座，底座的上端两
