Button clamping jig for button sewing machine

Abstract

The invention discloses a button clamping jig for a button sewing machine. The button clamping jig comprises an annular bottom ring and an annular top ring. A circular external thread pillar is formedon one side wall of the bottom ring. A rectangular inserting groove penetrating through the outer end face of the external thread pillar is formed in the inner side wall of the external thread pillar. Guide grooves penetrating through the upper end outer wall and the lower end outer wall of the external thread pillar are formed in the upper end face and the lower end face of the rectangular inserting groove. A U-shaped branch is formed at one end of a rubber ring. The branch of the rubber ring is inserted into the rectangular inserting groove of the external thread pillar. A vertical fulcrumshaft is connected into the branch of the rubber ring in an inserting mode. The two ends of the fulcrum shaft are exposed out of the outer wall of the external thread pillar and further abut against an internal thread regulating sleeve, and the internal thread regulating sleeve is in screw joint onto the external thread pillar. A plurality of guide holes are formed in the bottom ring, and guide pillars are connected into the guide holes of the bottom ring in an inserting mode. The upper ends of the guide pillars are fixed to the top ring. A plurality of fastening bolts are connected to the topring in an inserting mode, and the fastening bolts are in screw joint onto the bottom ring.

Description

technical field [0001] The invention relates to the technical field of clothing machinery, and more specifically relates to a button clamping jig of a button sewing machine. Background technique [0002] The button sewing machine is a kind of clothing machinery, and it is a kind of sewing machine. It is specially used to sew buttons on the clothes. The button needs to be positioned, and the function of the button clip is to position the button at the nailing position. At present, the buttons are usually clamped by two clamping fingers, and the clamping fingers need to be precisely positioned when the button is transported to the designated position, and at the same time, it is necessary to control the clamping force of the button, otherwise the force is too small and the button cannot be clamped or the force is too strong large, resulting in damage to the button, and the requirements for clamping and positioning the button with the fingers are relatively high; thus, a clamp...

AI Technical Summary

Problems solved by technology

At present, the buttons are usually clamped by two clamping fingers, and the clamping fingers need to be precisely positioned when the button is transported to the designated position, and at the same time, it is necessary to control the clamping force of the button, otherwise the force is too small and the button cannot be clamped or the force is too strong large, resulting in damage to the button, and the requirements for clamping and positioning the button with the fingers are relatively high; thus, a clamping structure using a rubber ferrule to clamp the button has been proposed, but the button is small in size and there is no suitable rubber ferrule, so the clamping Structurally, the adjustment structure of the rubber ring is required to realize the rubber ring clamping the button
