Description

A kind of new and improved dedicated ER type tube clamp nut spanner

Technical field

The utility model relates to a kind of new and improved dedicated ER type tube clamp nut spanners.

Background technique

There is a kind of collet chuck in cutting tool setting tool, is locked using ER (M) nut and the bite can be fixedly secured Tool, need to lock or unclasp the nut using spanner be that a kind of to have tooth socket be the spanner of six gradually helical teeth groove shapes, referred to as ER (M) spanner.The ER meaning of ER collet chuck, according to German Standard: one collet of collet, the spiral shell of DIN6499-2002 pad adjusting angle Female and fitting dimension, model are as follows: ER.DIN 69882/6-2000 wherein meets the tool holder with hollow taper shank of DIN69893-1 Six part of head-the: E type, the collet size of 8 ° of established angles of band.

Refering to the ER spanner (1) shown in the first figure, commonly used, generally all it is set as that there is one of opening (2) arc body (3), and by the number monocline cone cell convex teeth portion (4) of projection equal part on arc body (3) with the number monocline cone cell double wedge of this etc. point Portion is just able to be embedded in the number monocline cone cell tool engagement slot (5a) of ER nut (5) etc. point, rotates the ER spanner commonly used (1) lever (6) using equal point of the number monocline cone cell protrusion (4) and waits the number monocline cone cell tool engagement slot divided (5a) snap-fit relationship drive the ER nut (5) pine from or be fastened to the ER collet chuck (7), and then be able to dismount the bite Have (8).Admittedly but for equal point of the number monocline cone cell convex teeth portion (4) with etc. the number monocline cone cell tool engagement slot (5a) that divides Contact surface is inclined-plane, ER nut (5) is detached from so being very easy to operation ER spanner (1) and having slipped, when operator operates Because slippage will cause the unnecessary injury of personnel, and also can be because of the damage of cutting tool caused by the slippage of ER spanner (1) collision.

For problem present in the above conventional construction, a kind of innovation structure of more ideal practicability how is developed, Actually user is expected.In view of this, creator's sheet is in the manufacturing development and design experiences of being engaged in Related product for many years, for upper The target stated designs, in detail after reality die sinking test, obtains really tool this creation of the practicability after discretion assessment eventually.

Utility model content

To solve the above problems, the utility model provides a kind of new and improved dedicated ER type tube clamp nut spanner, keep away Exempt from nut discontinuity and generate modification, stuck conducive to being embedded in, being not easy, there is Dao Zheng Le energy.Foreign object is prevented to be caught in spanner, avoid knife The damage of bar thread increases using safe.

To achieve the above object, the technical solution that the utility model is taken are as follows:

A kind of new and improved dedicated ER type tube clamp nut spanner operates specific as follows: including arc body, increasing arc Body thickeies monocline face convex teeth portion, three width arcs breasting face and shank part；The arc body by integral forming is provided with shank part, institute It states to be integrally formed above arc body and is equipped with arc panel, the arc panel is the three width arc panel of shield tooth that three width arcs are more than semicircle, It is provided with three width arcs on the arc body and bears against face, the thickening list inclined convex of several equal portions is provided on the inside of the arc body Teeth portion thickeies monocline face convex teeth portion inner face and is equipped with gradually toward the widened inclined-plane in double wedge end, and the arc body inside is additionally provided with Increase arc body, it is described to increase arc body setting between thickening monocline face convex teeth portion.

Preferably, the three width arc panel height of shield tooth, which is higher than, thickeies monocline face convex teeth portion.

Preferably, the three width arc panel of shield tooth and ER collet nut cooperate and connect.

Preferably, being equipped with cutting tool on the ER collet nut.

The utility model structure is simple, easy to operate, ER spanner be further provided with three width arc bodies shield and sustain pull face nesting live should ER nut coats nut using three arcs, avoids skidding, loosen, bending；When anti-operation slip, block bits cause force when nut and Knife bar damage is reduced injured when operator uses.
