Description

Bottom scrap removing and positioning tool for bench drilling machine

Technical Field

The utility model belongs to the technical field of machinery, a bench drill removes end bits location frock is related to particularly.

Background

The high-locking bolt is widely applied to aircraft engines, and the machining method of the bottom driving groove of the bolt comprises the steps of drilling a bottom hole, punching a square and removing bottom scraps. In the square punching process, the punch generates instantaneous punching force on the bottom hole, and the punch has no chip removal structure, so that redundant chips cannot be discharged outwards, and the chips can be accumulated at the bottom of the groove. At present, there is some manufacturing enterprises to use bench drill to get rid of the end bits, and current bench drill gets the end bits frock and can't satisfy with the mode of bolt head location and gets rid of the end bits requirement, because the restriction of processing technology and equipment, there is certain axiality error in the relative pole portion of bolt head excircle, the relative pole portion of bottom hole also has the axiality error, because the accumulation of error, make the end bits often can get rid of unclean with the mode of head excircle location, can destroy drive slot nature shape more seriously, direct influence part assembly, influence the product delivery. And because the frock does not have any stop device, not only machining efficiency is low, still has very big potential safety hazard in the course of working, and traditional type frock is designed according to the big excircle size of head, and a frock can only be with two kinds of sizes that just tow sides are two kinds of sizes, and the frock of thickness is changed according to actual conditions ceaselessly, wastes time and energy.

Disclosure of Invention

An object of the utility model is to overcome above-mentioned shortcoming and provide a simple structure, it is high-efficient convenient, economical and practical, safe and reliable's bench drill removes end bits location frock.

The utility model discloses an aim at and solve its main technical problem and adopt following technical scheme to realize:

the utility model discloses a bottom scrap removing and positioning tool of a bench drilling machine, which is characterized in that; the upper pressing sheet is arranged on the die holder and screwed into the screw for connection, and the side surface of the die holder is inserted into the movable die core.

The upper part of the die holder is provided with a U-shaped clamping groove seat, and the lower part of the die holder is provided with a U-shaped groove.

The side surface of the pressing sheet is provided with an arc-shaped groove, and the pressing sheet can rotate on the die holder by taking a screw as a center.

The movable mold core is U-shaped, a protruding U-shaped clamping head is arranged in the middle of the movable mold core, and the protruding U-shaped clamping head is inserted into a U-shaped clamping groove seat arranged on the upper portion of the mold base.

Compared with the prior art, the utility model has obvious beneficial effects; the technical scheme shows that: the movable die core is inserted into the side surface of the die holder by placing a pressing sheet on the die holder and screwing the pressing sheet into a screw for connection. The die holder is internally provided with a U-shaped clamping groove seat, the movable die core is inserted into the die holder through the mutual matching of the U-shaped bulge of the movable die core and the U-shaped clamping groove seat of the die holder, the pressing sheet is arranged on the die holder, and the pressing sheet is pressed on the movable die core and the die holder. The lower part of the bottom of the die holder is provided with a U-shaped groove cavity which is suitable for placing the heads of different types of parts, the rod part of the part is transversely fixed through the limiting action of the movable die core and the pressing sheet, bottom scraps are removed through the positioning of the rod part, the influence of coaxiality errors on product processing is eliminated to the maximum extent, and the quality consistency of the product in the processing process is ensured; through the limiting action of the movable mold core and the pressing sheet, the rod part of the part is longitudinally positioned, so that when the punch moves away from the part, the part can be rapidly separated from the punch, the part can not rotate at a high speed due to adhesion on the punch, an operator does not need to take down the part by himself, the operator can not be accidentally injured, and the safety performance is greatly improved. The inner contour of the movable die core can be designed into different sizes according to the sizes of the rod parts of different parts, only different movable die cores need to be replaced when the movable die core is used, and the die holder and the inner parts of the movable die cores are U-shaped, so that the parts can conveniently enter and exit along U-shaped rails, and the processing efficiency is greatly improved. In summary; the utility model discloses simple structure, high-efficient convenient, economical and practical, safe and reliable.
