Clamp for sewing machine shell machining

Abstract

The invention relates to the field of sewing machine accessory machining, in particular to a clamp for sewing machine shell machining. The clamp comprises a machining table, a supporting mechanism used for containing a shell is arranged on the inner side of the machining table, a clamping mechanism used for fixing the shell is arranged on the upper side of the supporting mechanism, and the clamping mechanism is connected with a driving mechanism arranged on the outer side of the machining table. According to the clamp, By arranging the clamping mechanism, telescopic rods are utilized for pushing a connecting block to move, the connecting block drives a sliding block to move through a first connecting rod, and the sliding block drives clamping block to move through a second connecting rod to complete fixing the shell. By arranging the multiple telescopic rods, the device can complete fixing the shell from the left side and the right side, the shell can also be fixed from the front sideand the rear side, and then people can machine different faces of the shell conveniently. By arranging an adsorbing pipe and a sucker, under the effect of an air pump, the device can provide further fixing to the shell, and thus firmness of device fixing can be enhanced.

Description

technical field [0001] The invention relates to the field of sewing machine accessory processing, in particular to a fixture used for sewing machine shell processing. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. A general sewing machine consists of four parts: machine head, machine base, transmission and accessories. The head of the sewing machine is usually made of cast iron or aluminum alloy to obtain the sewing machine casing by casting process, and then the casing is processed into the machine head. [0003] Sewing machines require high machining accuracy, among which the machining of the sewing machine shell is a difficult point, and reaming is an important process in the process of casting the casting machine shell. Most of the workers fix the sewing machine shell one by one, and then perform reaming one by...

Problems solved by technology

However, the holes that need to be reamed in the housing of the sewing machine are distributed on different sides of the casing. When the worker performs the reaming operation, he usually needs to face up with the hole that needs to be processed so as to facilitate processing. The reaming surface of the reaming hole and the fixing of the casing have taken up more than half of the time of the entire reaming process, not only the labor intensity of the workers is high, but also the production efficiency is low. Therefore, in view of the above current situation, it is urgent to develop a sewing machine casing. Machined fixtures to overcome deficiencies in current practical applications
