Problems solved by technology

[0004] However, the center shaft in the current market is easy to fall off after being used for a certain period of time, which seriously affects the production efficiency. After the center shaft falls off, it is very likely to collide with the needle in the sewing machine, and the needle in the sewing machine is likely to break and fly out.

Embodiment 1

[0026] see figure 1 and figure 2 As shown, the sewing machine shuttle of the present invention includes an arc-shaped housing 1 and a central shaft 2, the arc-shaped housing 1 and the central shaft 2 are integrally formed, and the connection between the arc-shaped housing 1 and the central shaft 2 is provided with a reinforcement Structure 4, the reinforcement structure 4 refers to the excessive steps or fillets or chamfers integrally formed at the junction of the arc-shaped shell 1 and the central shaft 2. By integrally forming the arc-shaped shell 1 and the central shaft 2, it not only saves A spot welding process solves the problem that the central shaft 2 is difficult to fix at the preset position, makes the fixed position of the central shaft 2 accurate, and the central shaft 2 and the arc-shaped shell 1 are integrally formed, and the central shaft 2 and the arc-shaped shell 1 are tightly connected. Compared with the central shaft 2 welded on the arc-shaped housing 1, t...

Abstract

The invention discloses a sewing machine middle shuttle and a manufacturing method thereof, and is aimed at providing the sewing machine middle shuttle formed by integrating a central shaft and an arc-shaped shell. According to the technical scheme, the sewing machine middle shuttle and the manufacturing method are characterized in that the sewing machine middle shuttle comprises the arc-shaped shell and the central shaft which are integrally formed, the manufacturing method includes the steps of a, obtaining a middle shuttle blank through integral forming, wherein the middle shuttle blank at least comprises a rear shell body forming the arc-shaped shell and a column penetrating through the rear shell body; b, fixing the middle shuttle by clamping the portion, on the rear side of the rear shell body, of the column, forming the central shaft by turning the portion, on the front side of the rear shell body, of the column; c, milling away the portion, on the rear side of the rear shell body, of the column; d, obtaining the finished product, namely the middle shuttle through finishing and heat treatment. The middle shuttle blank is obtained through mold integral forming, the spot welding procedure is omitted, the problem that a central shaft can hardly be fixed to a preset position is solved, the fixed position of the central shaft is precise, and more importantly, the central shaft and the arc-shaped shell are integrally formed and closely and stably connected..

Description

technical field [0001] The invention relates to a middle shuttle, more specifically to a sewing machine middle shuttle and a manufacturing method thereof. Background technique [0002] The sewing machine industry is one of the important livelihood industries. The sewing machine is a precision machine, which is assembled from many precision parts, and the quality of the parts has a close influence on the performance and precision of the sewing machine. Among the precision parts of the sewing machine, the middle edge has the highest requirements for its shape complexity and precision. , so the middle edge becomes the most representative key part in the sewing machine. [0003] The existing sewing machine shuttles can be roughly divided into the following two categories: 1. Mainly use the plate as the material, and make the middle rib through stamping, forming, welding and other procedures. First, the plate is stamped into the front and rear shells of the middle rib. Then the...
