Description

A kind of fine setting tool rest structure

Technical field

The utility model relates to a kind of fine setting tool rest structure, refers to that especially a kind of adjustment screw rod is positioned on the body by a lining, and lining is provided with the positioning component of adjustable seamless power, and makes cutter fine setting operation convenient.

Background technology

Milling machine processing is the normal processing method of using of part processing, it must install a cutting tool that can rotate at a high speed with power source in the rotating shaft of milling machine processing machine, and general cutting tool binds and is combined on the tool rest, be fixed in the rotating shaft of milling machine processing machine by tool rest again, make cutting tool rotate the machining part at a high speed with rotating shaft, and cutting tool has the dimensions specification, to process different apertures, the processing larger aperture must be changed large diameter cutting tool, even boring a hole of trace, also the cutting tool that must change suitable diameter carries out reaming, quite bother, and a kind of adjustable tool rest structure is arranged at present on the market (as Fig. 7, shown in Figure 8), it is mainly by a body 60, adjusting seat 70 and one adjustment bolt 80 constitutes;

These body 60 1 ends are provided with a joint portion 61 that can be positioned board, the end face central authorities of the other end are equipped with the storage tank 62 that axially runs through, can place for cutter 50, differ from joint portion 61 1 ends at this body 60 and be equipped with the axis hole 63 that radially runs through, the inner peripheral of these axis hole 63 1 ends then forms ring-type retaining edge 630;

This adjustment bolt 80 is to be contained in the axis hole 63 of body 60, this adjustment bolt 80 forms a fixed part 83 towards axis hole 63 retaining edge 630 1 ends, this fixed part 83 protrudes from body 60 outer rims, the other end then forms a threaded portion 82, adjust position, bolt 80 stage casing at this and form bulge loop 81, and these retaining edge 630 outsides are by posting a dish type reed 90 and a dial 91, this dial 91 is mounted in the fixed part 83 of adjusting bolt 80, make dish type reed 90 be the state of suffering oppression, the medial surface formation location of the bulge loop 81 of bolt 80 near retaining edge 630 adjusted in order;

This adjustment seat 70 is to be contained in the axis hole 63 of body 60, this adjusts the relative body 60 end storage tanks of seat 70 outer rims 62 positions, be equipped with an embedding hole 71 and insert the embedding location for cutter 50, and this adjustment seat 70 is concaved with a screw 72 towards an end of adjusting bolt 80 and screws togather with 80 formation of adjustment bolt, these body 60 outer rim spiral shells are provided with the plane that seat 70 outer rims are adjusted in location screw 64 packings again, and adjustment seat 70 is located;

Above-mentioned tool rest structure is adjusted bolt 80 with the rotation of instrument (not shown) when adjusting

cutter

50,70 drive cutters 50 of this adjustment seat move, and make cutter 50 axle center and body 60 joint portions 61 central shafts form skew, adds by this can reach the effect of boring a hole man-hour.

Yet though existing tool rest structure can be by adjusting cutter 50 positions, to reach the effect of boring a hole, operation in the use is difficulty quite;

Because, these adjustment bolt 80 outer rims convex with bulge loop 81 by being attached to the medial surface of axis hole 63 retaining edge 630, retaining edge 630 opposite sides then are sequentially provided with dish type reed 90 and dial 91, this dial 91 also is combined in the fixed part 83 of adjusting bolt 80, make dish type reed 90 pressurizeds form elasticity and support power, the bulge loop 81 that causes adjusting bolt 80 is near retaining edge 630 inboards, and 91 of this dish type reed 90 and body 60 and dials also produce high frictional force;

Therefore, existing cutter structure is quite required great effort when adjusting, and when especially trace was adjusted, regular meeting the application of force took place is difficult to control, produces that the application of force kicks the beam or too quickly, causes adjusting bolt 80 and rotates not enough or turn over the situation of head, and can't accurately adjust, and causes the puzzlement in the use.

Therefore, creator of the present utility model in view of present tool rest structure in the use, still exist the adjustment resistance big, the use puzzlement that can't accurately adjust, and be engaged in the production and marketing experience for many years of tool rest Related product with it, and at the problem that present adjustment tool rest exists, the road of deep thinking improvement, and after repeatedly improveing and testing, create a kind of fine setting tool rest structure finally.

Summary of the invention
