Positioning hole jig used in slow-silk thread cutting machine

Abstract

The invention discloses a positioning hole jig used in slow-sill thread cutting machine, which is characterized by comprising a positioning hole plate and a tool-setting bushing, wherein the positioning plate is provided with plural-numbered positioning holes used for clamping workpieces; the tool-setting bushing and the positioning hole are matched with each other; the positioning hole plate is also provided with locking screws for fixing the workpieces. In the invention, the positioning hole plate which can be provided with plural-numbered workpieces is adopted and each positioning hole is provided with a tool-setting bushing, thus ensuring the clamping state of the simulation workpieces to enable the tool setting to be more accurate; and the locking screws are adopted to fix the workpieces, thus increasing installation stability of the workpieces. The invention has the advantages of simple structure, convenient operation, little nonproductive time, and low cost due to recycling of consumable items. The invention is worth being popularized and used.

Description

technical field [0001] The invention relates to a processing jig, in particular to a positioning hole jig for slow wire cutting. Background technique [0002] The slow wire is used to clamp the workpiece when processing cylindrical workpieces. Generally, it is used to cut a positioning hole with the same size as the outer diameter of the workpiece on an iron plate with a threaded hole on the front and a threaded hole on the side. Place in the hole, then run a screw into the threaded hole on the side to secure the piece. And because the iron plate does not grasp the positive angle cut positioning holes and is not labeled, the processing medium of slow wire is water and the iron plate is easy to rust, so the cut positioning holes are generally discarded after use. Moreover, it is necessary to process positioning holes for clamping, and the investment in auxiliary man-hours is large. Sometimes it takes longer to process the positioning holes of the workpiece than to process th...

Problems solved by technology

And because the iron plate does not grasp the positive angle, the positioning hole cut is not labeled, and the processing medium of slow wire is water. The iron plate is easy to rust, so the positioning hole cut is generally discarded after use.

Moreover, it is necessary to process positioning holes for clamping, and the investment in auxiliary man-hours is large. Sometimes the time to process the positioning holes of the workpiece is longer than the time to process the workpiece itself, and the cost of time and consumables is wasted on auxiliary processing, which in turn increases the cost of consumables.
