Multi-station grinding machine for processing needle bed inserts of computer flat knitting machine

Abstract

The invention relates to a multi-station grinding machine for processing needle bed inserts of a computer flat knitting machine, belonging to the technical field of grinding machines. The multi-station grinding machine comprises a grinding machine body, a workpiece table reciprocating motion device, a first sanding device, a second sanding device and a third sanding device, wherein one side of the grinding machine body in a length direction is matched with a first machine seat and a second machine seat which are mutually parallel, the other side is matched with a third machine seat, a first guide rail seat is respectively formed at two sides corresponding to an upper surface of the grinding machine body in the length direction, each first guide rail seat is fixedly provided with a first guide rail, and a first screw cavity is formed between a pair of first guide rail seats; the workpiece table reciprocating motion device is matched with each first guide rail in a sliding way; and the first sanding device is matched on the first machine seat in a sliding way, the second sanding device is matched on the second machine seat in a sliding way, and the third sanding device is matched on the third machine seat in a sliding way. The technical scheme not only can improve the sanding efficiency but also can ensure the workpiece quality.

Description

technical field [0001] The invention belongs to the technical field of grinding machines, in particular to a multi-station grinding machine for processing needle bed inserts of computerized flat knitting machines. Background technique [0002] The general shape of the needle bed inserts of the computerized flat knitting machine mentioned above can be seen from the China Appearance Design Patent Authorization Announcement Nos. CN300689754D and CN300816000D. The grinding (sanding) process of needle bed inserts is an extremely labor-intensive and time-consuming process. In the prior art, a drill press is usually used as a grinder, and the grinding wheel is installed on the drill press, that is, the grinding wheel is replaced by the drill bit, and the workers are constantly grinding.

The grinding (sanding) process of needle bed inserts is an extremely labor-intensive and time-consuming process. In the prior art, a drill press is usually used as a grinder, and the grinding wheel is installed on the drill press, that is, the grinding wheel is replaced by the drill bit, and the workers are constantly grinding. Move the head of the drilling machine to sand the inserts of the needle bed

Using a drill machine as a grinder to process (sand grind) the needle bed inserts has the following deficiencies: First, because the grooves on the needle bed inserts are special, the so-called particularity means that the grooves are small and have dovetail grooves, so they are located on the drill press. The diameter of the grinding wheel is usually small, and the smaller diameter of the grinding wheel is difficult to obtain the ideal line speed, unless it has a higher power speed, but the working speed of the drilling machine is difficult to meet the line speed requirements of the grinding wheel; After processing a certain surface of the needle bed insert, the needle bed insert must be re-clamped. Due to the limitation of the drilling machine structure, it is not possible to sand all the surfaces (at least three sides) of the needle bed insert at the same time. Grinding, which not only affects the efficiency of sanding, but also causes position deviation due to multiple clamping of needle bed inserts, which affects the quality of sanding

[0003] For a long time, manufacturers of computerized flat knitting machines and accessories manufacturers of computerized flat knitting machines have hoped to have a special device for sanding the needle bed inserts, but so far, neither in the literature nor in the market Seeing that there are successful examples, the applicant has carried out research and development, and the technical solution to be introduced below is produced under this background
