Abstract

The application discloses a sewing machine oil supply unit comprising a pump body, a rotating shaft, joints, a first fixed plate and a second fixed plate. The first fixed plate and the second fixed plate are both detachably arranged at two ends of the pump body, the rotating shaft is rotationally arranged in a containing cavity defined by the pump body, the first fixed plate and the second fixed plate, the rotating shaft penetrates through the first fixed plate, connection holes are formed in the pump body, and the joints are mounted in the connection holes; column feet, column covers and column springs are further included, circular plug holes are formed in the pump body, the column feet are circular column feet, the column covers are circular column covers, the column covers together arein cooperation in a threaded connection form, hexagonal screw holes are formed in the column covers, the column feet are movably arranged in the plug holes, one end of each column spring abuts against the column feet and the other end of the column spring abuts against the column covers, and the column springs are in a compressed state.

Description

technical field [0001] The invention relates to the field of sewing machine equipment, in particular to an oil supply device for a sewing machine. Background technique [0002] Many devices on the sewing machine need to use oil to lubricate, so an oil pump will be installed on the sewing machine to supply oil to the sewing machine. Patent CN206245033U provides a sewing machine oil pump. There is a problem in the use of this sewing machine oil pump, that is, each The clamping effect of the plunger (reference number 3 in the document) on the rotating shaft (reference number 2 in the document) relies on springs (reference number 7 in the document) and positioning plates (reference number 2 in the document) The clamping effect of serial number 4) is found in actual use. Due to the difference in precision of each plunger during processing, the fit clearance between each plunger and the rotating shaft when assembled on the pump body is inconsistent. The spring and a positioning p...
