Abstract
The utility model provides a thread tapper capable of being mounted on a conventional drilling machine. The thread tapper comprises a reducing rod, a screw tap fixing head and a connecting sleeve, the reducing rod is connected with the drilling machine and is connected with the screw tap fixing head by the connecting sleeve, two axial slide grooves are symmetrically arranged on the lower portion of the connecting sleeve, a dowel is transversely and perpendicularly connected to the upper portion of the screw tap fixing head, two ends of the dowel are mounted in the two axial slide grooves, and the screw tap fixing head can move up and down in the connecting sleeve. The connecting sleeve and the reducing rod are fixed by two first jackscrews symmetrically arranged. Two second jackscrews which are symmetrically arranged and used for fixing a screw tap are disposed on the screw tap fixing heads. When rotating, a drill pipe of the drilling machine drives the connecting sleeve, the screw tap fixing head and the screw tap to rotate, the screw tap starts tapping, once the screw tap contacts with a drilled hole, the screw tap can move downwards while tapping due to the fact that the screw tap fixing head can move up and down in the connecting sleeve, and at the moment, the screw tap automatically follows along with tapping operation. After tapping progress is completed, the drilling machine rotates reversely, the screw tap is withdrawn automatically, the drill pipe is lifted up, and an integral tapping process is completed.
Description
Technical field
The utility model relates to a kind of thread tapper that is contained on the conventional drilling machine, belongs to the machine tools technical field.
Background technology
Tapping at present mainly contains 3 kinds of methods: 1, hand is attacked: advantage is to be difficult for the fracture of wire awl, and shortcoming is slow, and labour intensity is big, and perpendicularity will be paid special attention to.2, tapping machine is attacked: advantage is a rapid speed, and quality has raising, flexibly (some occasion); Shortcoming is singly to buy a machine, and the price that has is more expensive.3, tap holder: advantage is a rapid speed, and quality has raising, and shortcoming is to need speed to cooperate, and requires the operative employee to be skilled in technique, the rapid wear silk, and the fracture of wire awl, the chuck requirements of making is high.
Summary of the invention
The purpose of the utility model is a kind of thread tapper that is contained on the conventional drilling machine of design, improves tapping speed, reduces labor intensity, and constantly screw tap does not decrease silk, make simply, and low cost, easy to operate.
The technical scheme of the utility model: the thread tapper that is contained on the conventional drilling machine of the utility model comprises reducing bar, the screw tap fixing head that is connected with drilling machine and is connected the reducing bar and the adapter sleeve of screw tap fixing head; The bottom symmetry of its adapter sleeve has two axial slides; Pin of the vertical connection of the upper lateral of screw tap fixing head; The two ends of pin are installed in two axial slides, and the screw tap fixing head can move up and down in adapter sleeve.
Described adapter sleeve and reducing bar are fixed by first jackscrew of two symmetric arrangement.
Fixedly two second jackscrews of the symmetric arrangement of screw tap are arranged on the described screw tap fixing head.
Described two groove millings that axial slide is long 60mm * 10mm.
The advantage of the utility model:
1, the utility model be let tapping-head be in can free up and down state, when tapping, bore moving main shaft and do not do the follow-up motion like this, just screw tap motion just can not damage screw thread.
2, connect in the many places of the utility model and the fastening jackscrew of using, make simply like this, the screw tap clamped condition is good, constantly screw tap.
3, whole device low cost of manufacture.
4, use regular tap or machine tapping awl, easy to operate.
The utility model can reach the fastest tapping speed of any chasing bar, attacks raising speed more than 10 times than hand, and has good quality, and workpiece can attacked after boring on the drilling machine, and simple to operate, has maloperation also unimportant.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the right view of Fig. 1.
The specific embodiment
Fig. 1, Fig. 2 are the structural representations of the utility model: the utility model be contained in the adapter sleeve 1 that thread tapper on the conventional drilling machine comprises reducing bar 2, the screw tap fixing head 3 that is connected with drilling machine and is connected reducing bar 2 and screw tap fixing head 3; The bottom symmetry of its adapter sleeve 1 has two axial slides 5; Pin 4 of the vertical connection of the upper lateral of screw tap fixing head 3; The two ends of pin 4 are installed in two axial slides 5, and the screw tap fixing head can move up and down in adapter sleeve 1.
Described adapter sleeve 1 is fixing by first jackscrew 6 of two symmetric arrangement with reducing bar 2.
Fixedly two second jackscrews 7 of the symmetric arrangement of screw tap 8 are arranged on the described screw tap fixing head 3.
Described two groove millings that axial slide 5 is long 60mm * 10mm.
The utility model links to each other with upright drill through reducing bar 2, and adapter sleeve 1 is fixing by first jackscrew 6 with reducing bar 2, cooperates tighter; Screw tap fixing head 34 is installed in the adapter sleeve 1 through pinning, and pin 4 can move up and down in two axial slides 5, and therefore, screw tap fixing head 3 can move up and down in adapter sleeve 1, but can not rotate with respect to adapter sleeve 1, but with adapter sleeve 1 rotation.Screw tap 8 is fixing by second jackscrew 7 with screw tap fixing head 3.
When the drilling machine drilling rod rotated, drilling rod drove adapter sleeve 1, screw tap fixing head 3, screw tap 8 rotations, and screw tap is once contact boring; The slight force degree; Screw tap 8 beginning tapping, stop to move down of reducing bar this moment, because screw tap fixing head 3 can move up and down in adapter sleeve 1; Move down in the time of the screw tap tapping, this moment, screw tap was along with the carrying out of tapping followed up automatically.When the tapping progress was accomplished, with the drilling machine counter-rotating, screw tap withdrawed from automatically, and drilling rod is mentioned, and whole tapping is accomplished.
The utility model does not have drilling rod to move downward in tapping process, makes tapping safety, the not bad screw thread of tapping.The jackscrew dynamics of fixed operating sleeve can make skids when tapping runs into when stopping, constantly screw tap.
