Description
Technical field
The utility model relates to the tapping field in machining, particularly relates to a kind of being specifically designed to and processes the tapping machine special of nominal diameter at the minor thread of 0.3 ~ 6mm.
Background technology
Tapping machine is a kind of machining equipment for work pieces process internal thread.When the minor thread using conventional tapping machine processing nominal diameter at 0.3 ~ 6mm, because the moment of torsion that can bear of corresponding screw tap is less, process plug tap is vulnerable to exceed the moment of torsion of this screw tap tolerance range and occurs that screw tap that screw tap fracture even can occur to rupture flies out the security incident of hurting sb.'s feelings.
For solving because screw tap moment of torsion is less, screw tap easy fracture, the screw tap that even can occur to rupture flies out the problem of the security incident of hurting sb.'s feelings, and those skilled in the art proposes a kind of tap chuck with overload protection function.As shown in Figure 1, the chuck 1 of overload protection function is with to comprise screw tap positioning sleeve 11, coupling body 12, steel ball 13, housing 14, butterfly spring 15 and adjusting nut 16.During work, adjusting nut 16 makes butterfly spring 15 produce pressure, coupling body 12 is coordinated to be locked at by steel ball 13 in the groove of coupling body 12, the groove of coupling body 12 and the ball on screw tap positioning sleeve 11 are cheated coordinate steel ball 13 is limited, when carrying out tapping operation, tapping spindle drives coupling body 12, and coupling body 12 drives screw tap positioning sleeve 11 by steel ball 13, thus drives screw tap to rotate tapping.When torsion suffered by screw tap is greater than the pressure of butterfly spring 15 generation; butterfly spring 15 is compressed; upper and lower two parts of coupling body 12 are got loose come; steel ball 13 just can shake off the restriction of butterfly spring 15; and cheated from coupling body 12 groove and ball on screw tap positioning sleeve 11 in the container cavity that matches and formed and extrude thus enter in the groove of housing 14; now; tapping spindle just can not drive screw tap positioning sleeve 11 to rotate when driving coupling body 12 to rotate again; there is screw tap skidding, thus play the effect of overload protection.
Because the use moment of torsion of different screw tap is different; the tapping machine of band overload protection function tap chuck is adopted to join a kind of corresponding tap chuck with regard to needing the screw tap for often kind of model; which not only adds the manufacturing cost of tapping machine; also need frequently to change tap chuck simultaneously, cause operating efficiency to reduce.In addition; because this tap chuck overload protection function is realized by the distortion of butterfly spring 15; and butterfly spring 15 elastic force after being repeatedly out of shape can diminish; need to do artificial adjustment by adjusting nut 16; to waste time and energy, and due to not data markers accurately, when tapping run into that material is hard, tapping is obstructed and the problem such as screw tap skidding time; adjusting nut 16 can only be regulated by rule of thumb to increase pressure, still have fracture screw tap or the inadequate risk of tapping torque.Therefore, when the screwed hole less to diameter carries out tapping, because screw tap moment of torsion is less, and the tap chuck degree of regulation of overload protection function is lower, easily occurs the accidents such as screw tap fractures, and can not meet minor thread processing request.
