Description

Threading, die head chasing, piercing machine

The utility model relates to a kind of multi-functional tapping, mantle fiber, drilling machine, belongs to the Small Universal plant equipment of processing various screws, screw and boring, is applicable to single-piece and batch process.

Existing tapping machine, die head threading machine and drilling machine are the equipment of function singleness, as replacing attacking die head threading machine with bench drill usually in China factory, pull positive and negative switch tapping and mantle fiber with hand.Its weak point is easily overheated burning out of motor, and switch is fragile, and screw tap easily breaks, inconvenient operation, and labour intensity is big, inefficiency.

The purpose of this utility model is to propose a kind of easy and simple to handlely, need not to pull positive and negative switch, only need after changing chuck, control crank press down and on lift, just can the multi-functional tapping of auto reversive general small-size, mantle fiber, drilling machine.

The purpose of this utility model is achieved in that this tapping, mantle fiber, drilling machine press from both sides folder, drill chuck, column, big arm, forearm, base, workbench and control crank etc. by vertical shaft, elevating screw, jackshaft, drilling rod axle, transmission device, tapping-head, quick change and form.On the base that column is contained in workbench links to each other, vertical shaft links to each other with crossbeam, and elevating screw drives big arm and rises or descend, and big arm is enclosed within rotatable 360 degree on the column.The utility model feature: 1. increased the forearm of linking 200 degree on the big arm, rotatable by jackshaft; 2. newly designed tapping-head, quick chuck and drill chuck, changing tapping-head and quick chuck on the drilling rod axle can tapping, mantle fiber, changes drill chuck and can hole.

The utility model has the advantages that: 1. adopt replaceable tapping-head, quick chuck, drill chuck, realize tapping, mantle fiber, boring, a tractor serves several purposes.2. use quick chuck both drillstock can be installed, again tap holder can be installed, changes easy, rapid, so when on same workpiece, processing the hole of different size or screw, need not pull workpiece and can once finish processing.3. big arm can revolve three-sixth turn, and forearm can rotate the flexible rotation of 200 degree, so convertible processing distance.4. the control crank screw tap can automatic positive and negative rotation, need not stir switch anyway, and is easy to operate, can reduce labor intensity, and compared with prior art, can improve 1～2 times of work efficiency.5. screw tap is driven by friction plate, and when having served as the carrying row, friction plate skids, thereby not fragile screw tap.
