Tool wrench

Technical Field

The utility model relates to a manual hardware and tools technical field, specific multipurpose hand tool spanner for numerical control machine tool that says so.

Background

At present, the digit control machine tool handle of a knife commonly used comprises nut and blind rivet two parts, and nut part and blind rivet part all need the eave tile spanner of corresponding specification and fork spanner to install and dismantle, but the handle of a knife still has specification problems such as JT40, JT50 among the actual work, and this eave tile spanner and solid wrench that just needs several kinds of different specifications, and current eave tile spanner comprises two eaves, has phenomenon such as the contact surface is little, the atress is uneven, drops easily, has certain potential safety hazard. A digit control machine tool uses the unfavorable safety of multiple instrument, lean production and 6S on-the-spot settlement management, uses different instruments when changing the handle of a knife moreover, and the operation is wasted time and energy, has increased the additional time for actual production, influences work efficiency.

Disclosure of Invention

The utility model aims at solving the technical deficiencies, provide a simple structure, reasonable in design, low in manufacturing cost, convenient to use can be used for numerical control machine tool's multipurpose hand tool spanner.

The utility model provides a scheme that its technical problem took is: a tool wrench is characterized in that a circular groove is formed in the left end of the wrench, 6 protruding hook heads are uniformly distributed in the groove, the width of each protruding hook head is smaller than that of a tool shank nut groove needing to be turned, a gap in working is effectively guaranteed, when the tool wrench is used, the six protruding hook heads are stressed simultaneously, the phenomena of slipping and groove disengaging can be prevented, and corners of the protruding hook heads are in arc transition, so that the strength of the protruding hook heads is enhanced, and the phenomenon of fracture is prevented; a round corner rectangular hole for JT40 knife handle blind rivet is arranged on the right side of the circular groove; the spanner middle part is equipped with the special tetragonal hole of hand awl (by M16~ M6), replaces the hand awl spanner, the unequal interval arrangement in tetragonal hole guarantees each side hole working strength, realizes that the hand awl taper hole only needs a instrument to solve, and the spanner afterbody is equipped with JT50 handle of a knife fillet rectangular hole for the blind rivet, and two fillet rectangular holes of spanner circular recess right side and spanner afterbody all are slightly bigger than handle of a knife blind rivet size, realize the clearance fit of two fillet rectangular holes and blind rivet, realize that fillet rectangular hole and blind rivet atress are even during the use, rotate the blind rivet more easily, realize clamping and uninstallation to the cutter.

The utility model relates to a rationally, simple structure can replace current two eave tile spanners and corresponding fork spanner, can not appear skidding, the grooving phenomenon, has increased the hand awl square hole moreover, consequently, not only possesses the function of ordinary eave tile spanner, also possesses the function of fork spanner, hand awl spanner moreover for aspects such as digit control machine tool handle of a knife and work piece hand awl, operation labour saving and time saving, convenience safe in utilization, the range of application is wide.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

The labels in the figure are: 1. circular groove, 2, protruding eave tile, 3, JT40 handle of a knife is fillet rectangular hole for the blind rivet, 4, square hole, 5, JT50 handle of a knife is fillet rectangular hole for the blind rivet.

Detailed Description

As shown in fig. 1: a tool wrench is characterized in that a circular groove 1 is formed in the left end of the wrench, six protruding hook heads 2 are uniformly distributed in the groove, the width of each protruding hook head 2 is smaller than that of a tool shank nut groove needing to be turned, a gap in working is effectively guaranteed, when the tool wrench is used, the six protruding hook heads 2 are stressed simultaneously, the phenomena of slipping and groove disengaging can be prevented, and the corners of the protruding hook heads are in arc transition, so that the strength of the protruding hook heads is enhanced, and the occurrence of a fracture phenomenon is prevented; the right side of the circular groove 1 is provided with a JT40 rounded rectangular hole 3 for a tool holder blind rivet; the spanner middle part is equipped with special tetragonal hole 4 of hand awl (by M16~ M6), replaces the hand awl spanner, 4 unequal interval arrangements in tetragonal hole guarantee each tetragonal hole 4 working strength, realize that the hand awl hole only needs a instrument to solve, the spanner afterbody is equipped with JT50 handle of a knife blind rivet and uses fillet rectangular hole 5, JT40 handle of a knife blind rivet is with fillet rectangular hole 3 and JT40 handle of a knife blind rivet all compare system handle of a knife blind rivet size slightly bigger with fillet rectangular hole 5, realize JT40 handle of a knife blind rivet with fillet rectangular hole 3 and JT40 handle of a knife blind rivet with fillet rectangular hole 5 and the clearance fit of blind rivet, realize fillet rectangular hole 3 during the use, fillet rectangular hole 5 is even with the blind rivet atress, rotate the blind rivet more easily, realize the clamping and the uninstallation of tool setting.

During the use, embolia six recesses on the digit control machine tool handle with six colluding heads (1, 2) in the head is circular, clockwise rotation tool spanner, the nut is screwed, and the nut is lifted off to anticlockwise rotation handle of a knife, embolias cutter body blind rivet department with fillet rectangular hole when fillet rectangular hole (3, 5) use, and clockwise rotation spanner, locking blind rivet, anticlockwise rotation spanner lift off the blind rivet, realize the blind rivet loading and unloading. In the using process of the square hole 4, a screw tap is placed into the corresponding square hole, and two hands forcibly rotate two ends of the tool wrench to realize tapping.

The utility model discloses simple structure can replace current two eave tile spanners and corresponding fork spanner, can not appear skidding moreover, the grooving phenomenon, has increased the hand awl square hole moreover, from this, not only possesses the function of ordinary eave tile spanner, also possesses the function of fork spanner, hand awl spanner moreover for aspects such as digit control machine tool handle of a knife and work piece hand awl, operation labour saving and time saving, convenience safe in utilization, the range of application is wide.
