Abstract
The utility model relates to a tool used for changing cutter of T72740 vertical fine boring and milling machine, which mainly aims to solving the problems of long time consumed in changing cutter and high working intensity in the existing T72740 boring and milling machine. The tool is characterized in that three upright posts (3) evenly distributed in circumference direction are connected on the upper part of a base (4); the tops of the upright posts (3) are connected with a circular support plate (1); the lower part of the inner side of the support plate (1) is provided with a lug boss (6) in circumference direction; and a locating bolt (5) vertical to an axis direction is connected on the side wall of the support plate (1). According to the tool, the structure is simple, and the cutter of the T72740 vertical fine boring and milling machine can be changed conveniently, so that the labor intensity of workers is reduced and the production efficiency is improved.
Description
Technical field
The utility model relates to mechanical field, a kind of specifically instrument that is used for the vertical right boring milling machine of T7240 cutter changing.
Background technology
Along with the development of aircraft industry, the aircraft that needs repairing is more and more, needs the workload of boring machine increasing.Wherein the vertical right boring milling machine of T7240 is a kind of equipment commonly used, needs often to change cutter, needs to need again in more than 1 hour the three people completion of cooperating jointly according to the method for routine replacement cutter at present, and this work just expends for a long time, and working strength is also very big.Certainly will the overall progress of processing parts be exerted an influence.
Summary of the invention
Change cutter length consuming time, deficiency that working strength is big in order to overcome existing T7240 boring and milling machine; The utility model provides the instrument of the vertical right boring milling machine of a kind of T7240 of being used for cutter changing; This tool construction is simple, the vertical right boring milling machine of replacing T7240 convenient cutter; And can reduce labor strength, increase work efficiency.
The technical scheme of the utility model is: the instrument of the vertical right boring milling machine of a kind of T7240 of being used for cutter changing; Comprise base; Described base top is connected with three columns that circumferentially are uniformly distributed with; The column top is connected with the supporting plate of annular, and described supporting plate lower inside circumferencial direction is provided with boss, and is connected with the bolt vertical with axis direction on the supporting plate sidewall.
Be connected through bolt between described column and supporting plate, described base be provided with and lathe between the draw-in groove that fixes.
The utlity model has following beneficial effect: owing to take such scheme; This instrument can be held the machine tool jig through supporting plate; Make the cutter radial location through the positioning of rotating bolt again; Damage cutter and main spindle multiple spline when avoiding the dismounting cutter, just can change cutter easily in conjunction with the elevating function of machine tool chief axis.Compare with the method for routine replacement cutter, can save for 3/4ths time, and a people just can independently accomplish, improve efficient, reduce labour intensity.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the vertical view of the utility model.
1-supporting plate among the figure, 2-bolt, 3-column, 4-base, 5-bolt, 6-boss, 7-draw-in groove.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
By Fig. 1 and shown in Figure 2, a kind of instrument that is used for the vertical right boring milling machine of T7240 cutter changing comprises base 4, base 4 be provided with and lathe between the draw-in groove 7 that fixes, bolt is passed draw-in groove 7 just can base 4 be fixed on the lathe.Described base 4 tops are connected with three columns that circumferentially are uniformly distributed with 3, can weld between column 3 and the supporting plate 1, also can connect through bolt 2.Column 3 tops are connected with the supporting plate 1 of annular; Described supporting plate 1 lower inside circumferencial direction is provided with boss 6; The internal diameter of supporting plate 1 is a bit larger tham the external diameter of machine tool jig; The internal diameter of boss 6 is then less than the machine tool jig, make cutter together pass supporting plate 1 with jig after, jig drops on the boss 6.And be connected with the bolt vertical 5 on supporting plate 1 sidewall, when mounting cutter,, cutter and machine tool chief axis aligned, avoid spline to damage through the bolt 5 of tightening different directions with axis direction.
When changing cutter, earlier machine tool chief axis is risen, this instrument is fixed on the lathe below of fixing a cutting tool; Main shaft then descends; The machine tool jig dropped on this instrument fix, again with the cutter jig by pulling down on the lathe, machine tool chief axis risen just can make the cutter jig separate with machine tool chief axis.When mounting cutter, get final product according to opposite operation in tandem.
Claims (2)
1. instrument that is used for the vertical right boring milling machine of T7240 cutter changing; Comprise base (4); It is characterized in that: described base (4) top is connected with three columns that circumferentially are uniformly distributed with (3); Column (3) top is connected with the supporting plate (1) of annular, and described supporting plate (1) lower inside circumferencial direction is provided with boss (6), and is connected with the bolt vertical with axis direction (5) on supporting plate (1) sidewall.
