Abstract
The utility model relates to machine tool machining equipment, in particular to a machine tool machining deep blind hole boring head device, aiming at solving the problem of scratching workpieces when the deep blind hole boring head withdraws. The device comprises springs, an adjustable tool post and a rotating tool holder, wherein the rotating tool holder is fixed on the adjustable tool post by a pin shaft and is provided with a fixed tool post, the two springs are arranged on one side of the adjustable tool post, an adjustment screw is positioned between the two springs and is provided with an adjustment nut, the fixed tool post is fixed on a boring bar and is provided with support strips on both sides. When the boring head withdraws, the rotating tool holder can turn along with the pin shaft to avoid damaging the surfaces of the process holes due to collision, and can also feed radially by trimming to realize accurate processing of the inner holes of the workpieces.
Description
Technical field
The utility model relates to a kind of machine tooling equipment, specifically is the dark blind hole boring head of a kind of machine tooling device, to solve the problem of pulling workpiece when the processing deep blind-hole boring head withdraws from workpiece.
Background technology
At present, in field of machining, during the processing parts deep via, all be to adopt to advance from an end boring, take out boring head from the other end, withdraw from the operation of knife bar then, but for the processing of dark blind hole, boring head can only be by same end advance and retreat, boring head is when withdrawing from workpiece, cutter is easy to pull the workpiece inwall, causes waste product, has strengthened production cost.
Summary of the invention
The utility model is for overcoming above-mentioned the deficiencies in the prior art part, a kind of dark blind hole boring head device is provided, but but have the boring head device that the rotor seat reaches the radiai adjustment knife rest, but the rotor seat is fixed on by bearing pin and regulates on the knife rest, in a side of regulating knife rest two springs are arranged, control to adjust knife rest and workpiece applying degree by spring, regulate its bore hole size by adjustable nut, when boring head withdraws from, but the rotor seat can rotate with bearing pin, the hole surface of avoiding damaging, but also can radially finely tune feeding, realize accurate processing to the workpiece endoporus.
The purpose of this utility model realizes with following technical scheme: a kind of dark blind hole boring head device, it is characterized in that: it comprises spring, regulates knife rest, but the rotor seat is fixed on by bearing pin and regulates on the knife rest, but on the rotor seat immovable support is arranged, in a side of regulating knife rest two springs are arranged, there is adjusting screw(rod) the centre of two springs, and adjusting nut is arranged on the adjusting screw(rod), immovable support is fixed on the boring bar, and there is support strip the immovable support both sides.
On the described adjusting screw(rod) adjusting nut is arranged, can regulate the boring cutter radial dimension.
But described rotor seat is fixed on by bearing pin and regulates on the knife rest, but the rotor seat can rotate around pin.
The utility model has the advantages that: this apparatus structure is simple, and is easy for installation, but described rotor seat can rotate with bearing pin, the hole surface of avoiding damaging, but also can radially finely tune feeding is realized the accurate processing to the workpiece endoporus.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model structural representation:
Fig. 2 is the vertical view of Fig. 1:
Fig. 3 is the revolved view of Fig. 1:
Among the figure: 1, spring, 2, regulate knife rest, but 3 rotor seats, 4, immovable support, 5, support strip, 6, adjusting nut, 7, adjusting screw(rod), 8, spring, 9, bearing pin.
The specific embodiment
As shown in the figure: a kind of dark blind hole boring head device, it comprises spring 1, regulates knife rest 2, but rotor seat 3 is fixed on by bearing pin 9 and regulates on the knife rest 2, but immovable support 4 is arranged on the rotor seat 3, have the centre of 8, two springs of two springs that adjusting screw(rod) 7 is arranged in a side of regulating knife rest 2, adjusting nut 6 is arranged on the adjusting screw(rod), immovable support 4 is fixed on the boring bar, and there is support strip 5 the immovable support both sides, influences the surface of the work crudy to avoid boring bar because of shake takes place the rigidity deficiency in the boring process.
On the described adjusting screw(rod) 7 adjusting nut 6 is arranged, can regulate the boring cutter radial dimension.
But described rotor seat 3 is fixed on by bearing pin 9 and regulates on the knife rest 2, but rotor seat 3 can make boring cutter remain slight the contact with the workpiece inwall around pin 9 rotations, is unlikely and pulls work piece inner surface.
