Abstract

The utility model relates to a wedge-pressure type hard alloy blind hole floating boring tool. On the premise that the appearance and the diameter of a tool body are adjusted, and the tool body is matched with the original toolbar, inclined through slots of which one-surfaces are provided with upright teeth are formed in cutting parts at the left end and the right end of the tool body; a blade of which one surface is provided with the same upright teeth and has the same gradient is pressed into each slot in a wedge manner; transitional cutting edges of the two blades are arranged outside the cutting parts of the left side and the right side of the tool body; when the blades can be replaced after being abraded to the maximum extent and are not limited by one type of cutting materials.

Description

Wedge pressure type carbide alloy blind hole floating boring tool

Technical field

This wedge pressure type carbide alloy blind hole floating boring tool, particularly a kind of this wedge pressure type carbide alloy blind hole floating boring tool that can use at all kinds of horizontal lathes and boring machine.

Background technology

At China's carbide alloy floating boring tool since coming out the sixties in last century, the connection of blade and cutter hub is welded type, blade service life is low and mostly be the processing through hole and can't processing blind hole class part, whenever blade abrasion to the limit, whole cutter hub is namely abrogated, thus the waste that brings cutter hub material and cutter to make, and the utility model relates to a kind of wedge pressure type carbide alloy blind hole floating boring tool, be particularly related to a kind of can the use at all kinds of horizontal lathes and boring machine, thereby overcome above drawback.

Summary of the invention

Goal of the invention of the present utility model will overcome above-mentioned deficiency exactly, and a kind of wedge pressure type carbide alloy blind hole floating boring tool of simple and direct easy operating is provided.

The technical solution of the utility model is as follows: a kind of wedge pressure type carbide alloy blind hole floating boring tool, cooperate under the constant prerequisite in cutter hub profile and diameter adjustment thereof with former knife bar, partly be equipped with the gradient groove of the perpendicular tooth of one side in the cutting of two ends, the cutter hub left and right sides, the blade wedge that is shaped on the perpendicular tooth of identical one side and gradient is pressed in its groove, two blade transitional edges all are located at outside the cutting tip of the cutter hub left and right sides, renew and be not subjected to a kind of restriction of cutting material under blade abrasion is detachable to the limit.

Cutting tip its groove one side gradient in the left and right two ends of described cutter hub is 5 °, 60 ° of the perpendicular tooth profile angles of groove bottom, tooth pitch 0.5～0.8mm.

Described two blade transitional edges all are located at outside the cutting tip of cutter hub two ends, and it exposes width must be less than the processing parts grinding undercut.

Renew under described blade abrasion is detachable to the limit, different according to the processing parts material, its blade material can be selected the high-speed steel of the various different trades mark for use.

Description of drawings

Further specify the utility model below in conjunction with the drawings and specific embodiments.

Fig. 1 is the utility model general assembly drawing;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the top view of Fig. 1;

Fig. 4 is the enlarged drawing of Fig. 3 M groove.

The specific embodiment

As shown in Figure 1, wherein 1 is blade, 2 is housing screw, 3 is cutter hub, cooperate under the constant prerequisite in cutter hub profile and diameter adjustment and former knife bar, two ends, cutter hub left and right sides cutting tip is equipped with the gradient groove of the perpendicular tooth of one side, the blade wedge that is shaped on the perpendicular tooth of identical one side and gradient is pressed in its groove, and two blades must expose cutter hub lateral width e value must be less than the processing parts grinding undercut.

Fig. 2 is cutter hub groove and blade 5 ° of wedges pressures connection each other, and the last splenium of the perpendicular tooth skewed slot of cutter hub both sides band divides thickness H value to be not less than 4mm.

Fig. 3 is the perpendicular tooth wedging of being of cutter hub and blade, and the self-locking performance spy is good, does not weld flawless blade wearability height.

Fig. 4 is 60 °, tooth pitch 0.5～0.8mm for the profile angle of cutter hub and the connection of blade groove, machine by wire cutting machine tool, when blade normal wear in cutting use of can constantly refacing, after it wears up to the limit, can from skewed slot, draw off blade, institute renews blade cutter hub behind sharpening and can continue to use, and prolongs cutter life and has reduced production cost.

The utility model can also can be selected carbide alloy or the high-speed steelknife sheet material of the different trades mark, to finish the processing to all kinds of blind hole parts according to the part of processing different materials.

Claims
