Abstract
The invention provides a kind of tap wrench balancing radial force, can conveniently check tapping depth, to reach to prevent screw tap from fractureing, improve the purpose of work efficiency simultaneously.Screw in during preformed hole at screw tap, not only need axial force to rotate screw tap, in addition it is also necessary to apply certain radial force, owing to operator's both hands exert oneself unbalanced to cause screw tap to tilt, it is easy to make to fracture with the screw tap in access aperture.The present invention limits the radial force of screw tap by sleeve so that it is during tapping, smoothness is stable, is not easily broken.
Description
Technical field
The present invention relates to a kind of machining tool, a kind of tap wrench preventing screw tap from fractureing, belong to mechanical mounting techniques neck
Territory.
Background technology
In the installation production process of engineering goods, often use tap wrench that hole is carried out tapping, in order to install solid
The various parts of fixed output quota product.Traditional tap wrench is typically all made up of simple chuck and cantilever inserted link, passes through inserted link
Increase moment of torsion, make in screw tap advances through hole.During screw tap screws in preformed hole, not only need axial force to rotate screw tap, go back
Need to apply certain radial force, owing to operator's both hands exert oneself unbalanced to cause screw tap to tilt, it is easy to make to have been enter in hole
Screw tap fracture.During processing blind hole screw thread, screw tap will moment at the bottom of contact hole, operator is not it is realized that still by not arriving
Screwing speed at the bottom of hole is sent into, and will also result in screw tap and fractures.Being partially left in hole of fractureing is difficult to take out, and loses time and material
Material, has a strong impact on the efficiency of work.
Summary of the invention
In order to solve the problem fractureed at tapping process plug tap, the invention provides a kind of tapping balancing radial force and pull
Hands, can conveniently check tapping depth, to reach to prevent screw tap from fractureing, improve the purpose of work efficiency simultaneously.
A kind of tap wrench preventing screw tap from fractureing: mainly have by with the expansion link of ratchet chuck, the sleeve of outside and
Afterburning inserted link composition.It is carved with scale on expansion link, facilitates operator to read the degree of depth shooting screw thread.Sleeve is mainly used in limiting footpath
Xiang Li, prevents screw tap from tilting to fracture.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention each parts of a kind of tap wrench preventing screw tap from fractureing.
Fig. 2 be the present invention a kind of prevent screw tap from fractureing tap wrench work time diagrammatic sectional view.
In figure: 1 expansion link, 2 through holes, 3 inserted links, 4 ratchet chucks, 5 screw taps, 6 quarters
Degree, 7 sleeves, 8 end caps, 9 symmetrical openings, 10 springs, 11 thrust ball bearings.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is specifically described:
As depicted in figs. 1 and 2, the present invention provides a kind of tap wrench, and main body is made up of the sleeve 7 of expansion link 1 and outside, and two
Connected by spring 10 and thrust ball bearing 11 between person.There is through hole 2 expansion link 1 upper end, facilitates the installation of inserted link 3, lower end with
Ratchet chuck 4, can fix the screw tap 5 of different-diameter during work.Expansion link 1 shaft indicates scale 6, facilitates the reading of tapping depth
Take.Sleeve 7 has screw thread inside lower end, is used for being screwed into end cap 8, and end cap 8 can limit sliding scale and the reinforcing sleeve of expansion link 1
The stability that cylinder 7 contacts with work surface.In the rectangle symmetrical openings 9 that a pair width of leaning to one side near sleeve 7 lower end is moderate,
Operator is facilitated to observe tapping situation.
During tapping, fix screw tap 5 with ratchet chuck 4, catch 7 screw taps 5 of sleeve to be directed at preformed hole, mild pressure on the other hand
Lower sleeve 7 so that it is under along 8 and absorption surface, sleeve 7 is vertical with workpiece planarization.Expansion link 1, screw tap 5, sleeve 7 and preformed hole four
Person is concentric.Then another hands rotates inserted link 3 with certain pressure, makes flexible contracting bar 1 drive in screw tap 5 threaded through bores.In work
During, observed the situation of tapping by the symmetrical openings 9 on sleeve 7, read screw thread by the scale 6 on expansion link 1
The degree of depth.Due to the restriction of sleeve, the expansion link 1 accompanying screw tap 5 can only slide up and down, thus eliminates screw tap 5 unbalance stress
Weighing apparatus, causes inclination to fracture.Scale 6 on expansion link allows operator have one to the depth of thread and estimates well, it is to avoid processing
During blind hole, screw tap 5 fractures with contacting at the bottom of hole to cause.
