Problems solved by technology

[0003] The purpose of the present invention is to overcome the defects of low installation accuracy of the middle seat of the existing milling sewing machine, which is easy to cause the sewing machine to be stuck, and is easy to interfere with other parts when it is installed on the sewing machine. The transmission accuracy can effectively prevent the sewing machine from being stuck due to the entry of impurities such as thread ends and rags during the sewing process. There is enough space inside the housing to accommodate the transmission parts, and there is no interference with other parts of the sewing machine. The parts inside the housing with sufficiently high shape and position accuracy between

Embodiment Construction

[0016] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0017] A middle seat of a sewing machine, comprising a mounting plate 2, a shell 5, and a card seat 3. The whole middle seat of the sewing machine is obtained by casting, the card seat 3 is located on the left side of the mounting plate 2, and there is a gap between the two, and the shell 5 is located on the right side of the mounting plate 2. The card holder 3, the mounting plate 2 and the housing 5 are integrated. When installing, the mounting plate 2 is fixed in the groove of the sewing machine base. 8 fits with the base and is fixed with screws. The upper surface 7 of the housing 5 is a casting surface and does not need to be processed. The bottom surface 4 and the side surface 1 of the housing 5 are joint surfaces with high precision require...

Abstract

The invention discloses a middle seat of a sewing machine, and belongs to the technical field of design of sewing machine parts. The middle seat comprises a mounting plate, a shell and a clamping seat, wherein the whole middle seat of the sewing machine is obtained by casting; the clamping seat is located on the left side of the mounting plate, and a gap is reserved between the clamping seat and the mounting plate; the shell is located on the right side of the mounting plate; the clamping seat, the mounting plate and the shell form a whole; the upper surface of the shell is a casting surface and does not need to be machined; both the bottom surface and the side surface of the shell are combination surfaces, so that the precision requirement is high, and the bottom surface and the side surface need to be milled and formed on a milling machine. According to the middle seat of the sewing machine, the transmission precision of the sewing machine can be improved favorably, and the phenomenon that the sewing machine is blocked by impurities, such as thread ends and shreds, entering the sewing machine in a sewing process is effectively prevented; an enough space for accommodating transmission parts is reserved in the shell, and no interference with other components of the sewing machine is avoided; all the parts in the shell have enough high shape and position precision.

Description

technical field [0001] The invention relates to the technical field of sewing machine component design, in particular to a sewing machine middle seat. Background technique [0002] The middle seat of the sewing machine is a support on the sewing machine and an installation part of the transmission system. The sewing precision of the sewing machine is low, so the design is conducive to improving the transmission precision of the sewing machine, effectively preventing the sewing machine from being stuck due to impurities such as thread ends and rags during the sewing process. There is enough space inside the housing to accommodate the transmission parts. And without interference with other parts of the sewing machine, it is very necessary to have a sewing machine middle seat with sufficiently high shape and position accuracy between the parts inside the housing. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of low install...
