Sewing machine bottom plate machining device

Abstract

The invention discloses a sewing machine bottom plate machining device. The sewing machine bottom plate machining device includes a machining tool and propelling devices, drilling mechanisms and a locating clamp which are located on the machining tool, the machining tool includes bases and a shell body, and the locating clamp is located between the bases; the two propelling devices for propellingthe drilling mechanisms to move close to the locating clamp and are separately located at two sides of the locating clamp, each of the propelling devices is connected with each of the drilling mechanisms which include a plurality of drilling tools, and drilling tool anti-bouncing mechanisms are fixed in the feed direction of the drilling tools; the precision of holes after being machined and the coaxiality between the holes can be ensured by drilling tool sleeves; the coincident feed speed of a plurality of combined tools can be ensured; and workpieces can be pressed tightly through hydraulicclamping devices to enable the pressure of pressing blocks to be suitable, and the workpieces are not damaged.

Description

technical field [0001] The invention relates to the field of sewing machine processing, in particular to a sewing machine bottom plate processing device. Background technique [0002] In the prior art, when the bottom plate of the sewing machine is processed with holes, each processing of a hole is a process. This processing method has relatively big problems: [0003] 1. In the process of processing, the workpiece or the tool needs to be moved, and errors will occur when moving, and it needs to be repositioned or eliminated by means of compensation, which leads to expensive processing devices; [0004] 2. Due to the relatively high requirements on the coaxiality of multiple holes on the bottom plate, relatively long drills are basically used now to process multiple holes on the bottom plate with one feed to ensure the coaxiality of multiple holes. However, because the drill bit is too long, the drill bit will jump when drilling, resulting in that the machining accuracy of...

Problems solved by technology

[0003] 1. In the process of processing, the workpiece or the tool needs to be moved, and errors will occur when moving, and it needs to be repositioned or eliminated by means of compensation, which leads to expensive processing equipment;

[0004] 2. Due to the relatively high requirements on the coaxiality of multiple holes on the bottom plate, relatively long drills are basically used now to process multiple holes on the bottom plate with one feed to ensure the coaxiality of multiple holes. However, because the drill bit is too long, the drill bit will jump when drilling, resulting in that the machining accuracy of the hole is not up to standard after processing.

[0005] Due to the above two reasons, the processed bottom plate may not match the parts, and the bottom plate is useless, requiring re-melting, molding and processing, wasting a lot of manpower and material resources
