Abstract
The utility model relates to a flexible tap for the tapping of a combined machine tool. The flexible tap comprises a transition rod (1), a connecting rod (2), a sleeve (3), a peaking shaft (4), a spring (5), a spherical pin (6) and a tap (7) and the like; the spring (5) is installed in a spring hole of the transition rod (1); one end of the sleeve (3) is sleeved on the transition rod (1) and the other end of the sleeve is sleeved on the connecting rod (2); the tap (7) is arranged at the other end of the connecting rod (2); the peaking shaft (4) and the spherical pin (6) are arranged between the transition rod (1) and the connecting rod (2) in the sleeve (3); a cylindrical surface of the spherical pin (6) is of a sphere shape; one end of the peaking shaft (4) stretches into the spring hole of the transition rod (1) and is pushed against the spring (5); and the spherical pin (6) is arranged between the peaking shaft (4) and the connecting rod (2). As the flexible tap disclosed by the utility model is provided with the spring (5) and the spherical pin (6) and should make up a certain out-of-tolerance range of eccentricity between the tap and a screw hole, the flexible tap has the characteristics of improving work efficiency and avoiding occurrence of tap broken situations.
Description
Technical field:
The utility model relates to the flexible screw tap that a kind of building-block machine tapping is used.
Background technology:
At present; In tapping on the building-block machine all is that the screw tap of usefulness is contained in directly tapping on the anchor clamps of lathe, and when tapping, the degree of eccentricity at center, screw tap centrally aligned silk hole has certain requirement; This just requires operating personnel that higher operant level will be arranged, and has influenced operating efficiency.When particularly on building-block machine, attacking a plurality of holes simultaneously, complicated operation has greatly influenced work efficiency.Overproof because of screw tap in addition with the silk hole degree of eccentricity, be prone to cause the phenomenon of fracture of wire awl to take place.
Summary of the invention:
The purpose of the utility model is the tapping for building-block machine, and particularly carrying out a plurality of tapping simultaneously provides a kind of flexible screw tap.
For realizing above purpose, the technical scheme of the utility model is: include transiting rod, connecting rod, sleeve pipe, apical axis, spring, ball pin, screw tap etc.One end of transiting rod is provided with spring eye, and spring is contained in the spring eye, and an end of sleeve pipe is sleeved on this end of transiting rod; The other end of sleeve pipe is sleeved on the connecting rod; Screw tap is contained on the other end of connecting rod, in sleeve pipe, between transiting rod and the connecting rod, apical axis, ball pin is housed, and the face of cylinder of ball pin is ball-type; One end of apical axis puts in the spring eye of transiting rod and withstands spring, and ball pin is contained between apical axis and the connecting rod.
During use, the other end of transiting rod is contained on the jig, drives transiting rod by jig, transiting rod drives connecting rod through sleeve pipe, and connecting rod drives screw tap and carries out the tapping operation.Because the utility model is provided with spring and ball pin, should be able to remedy certain screw tap and the overproof scope of the silk hole degree of eccentricity; Owing to be provided with spring, before screw tap carries out tapping to the silk hole, produce a pretightning force in addition, can guarantee that also a plurality of screw taps carry out the tapping operation simultaneously.Can increase work efficiency and avoid the generation of fracture of wire awl phenomenon greatly.
Description of drawings
Accompanying drawing 1 is the utility model sketch map.
The specific embodiment:
An embodiment for the utility model includes transiting rod 1, connecting rod 2, sleeve pipe 3, apical axis 4, spring 5, ball pin 6, screw tap 7 etc.One end of transiting rod 1 is provided with spring eye; Spring 5 is contained in the spring eye, and an end of sleeve pipe 3 is sleeved on transiting rod 1 this end, the other end is sleeved on the connecting rod 2, and screw tap 7 is contained on the other end of connecting rod 2; In sleeve pipe 3, between transiting rod 1 and the connecting rod 2, apical axis 4, ball pin 6 are housed; The face of cylinder of ball pin 6 is ball-type, and an end of apical axis 4 puts in the spring eye of transiting rod 1 and withstands spring 5, and ball pin 6 is contained between apical axis 4 and the connecting rod 2.Apical axis 4 withstands ball pin 6 under the effect of spring 5, ball pin 6 is withstood connecting rod 2.Because the face of cylinder of ball pin 4 is the ball-type face, connecting rod 2 can be along the certain angle of ball-type face swing of ball pin 4.
During use, the other end of transiting rod 1 is contained on the jig, drives transiting rod 1 by jig, transiting rod 1 drives connecting rods 2 through sleeve pipe 3, and connecting rod 2 drives screw taps 7 and carries out the tapping operation.Because the utility model is provided with spring 5 and ball pin 6, should be able to remedy certain screw tap and the overproof scope of the silk hole degree of eccentricity; Owing to be provided with spring 5, before tapping is carried out in 7 pairs of silk holes of screw tap, produce a pretightning force in addition, can guarantee that also a plurality of screw taps 7 carry out the tapping operation simultaneously.Therefore the utlity model has and increase work efficiency, avoid the characteristics such as generation of fracture of wire awl phenomenon.
