Clamper for reaming embroidery machine case

Abstract

The invention discloses a fixture applied to a casing reaming of an embroidery machine. The fixture comprises a fixing base. An installation plate which can rotate is vertically arranged on the fixingbase. A row of four hinge sleeves is arranged on the installation plate. One side of the installation plate is provided with a bending fixing arm. A closing-up cylinder which can close a casing up tothe installation plate is arranged on the fixing arm. The other side of the installation plate is articulated with a retractable arm. One end of the retractable arm is articulated with the installation plate, and the other end is connected with the fixing arm in a locking way. An elastic close-up mechanism which can close the casing up to a positioning abutment plate on the opposition side of theinstallation plate is arranged on the retractable arm. And the hinge sleeves are connected with the installation plate in a sliding way by a swallow tail chute and a swallow tail platform and are locked and positioned by a locking bolt. In the technical scheme, the hinge sleeves are fixed on the fixing base in a demountable way, so that Worn hinge sleeves can be changed conveniently. The elasticdevice and cylinder pressurizing are adopted to overcome the problems of low processing precision and slow processing speed caused by the unequal pressure of artificial pressurizing. The fixture applied to the casing reaming of the embroidery machine has the advantages of convenient operation, uniform fixing power, high processing precision, etc.

Description

technical field [0001] The invention belongs to the field of tooling equipment, in particular to a clamp for reaming holes in an embroidery machine casing. Background technique [0002] The casing of the embroidery machine needs to be equipped with a driving shaft, so special fixtures are used to ream holes on the upper and lower end walls of the casing and install the driving shaft. Since the driving shaft is directly connected to the driver by sliding, the accuracy of the movement of the driver Directly affected by the perpendicularity of the drive shaft, reaming accuracy is critical. The reaming fixture includes a fixed seat, on which a rotatable mounting plate is vertically arranged, and a row of four hinge sleeves are arranged on the mounting plate, between two hinge sleeves are used to install the upper end wall of the casing to be processed and lower end wall. In the prior art, the hinge sleeve is fixed on the mounting plate and cannot be disassembled, so that it ca...
