Description

A kind of groove instrument that is used for CNC milling machine

Technical field

The utility model relates to a kind of groove instrument that is used for CNC milling machine.

Background technology

A lot of special toolings in the factory like drill jig, marking-off plate etc., need be carved datum line on drill jig, marking-off plate; To guarantee the frock service precision, the manual line of existing baseline methodology employing at quarter, groove cause graduating accuracy low; Graduating accuracy is about 0.5mm; Especially on inclined-plane or curved surface during groove, precision is difficult to guarantee that working (machining) efficiency is low.

The utility model content

The problem that the utility model is low for solution baseline methodology graduating accuracy at existing quarter, working (machining) efficiency is low, and then a kind of groove instrument that is used for CNC milling machine is provided.

The utility model is to solve the problems of the technologies described above the technical scheme of taking to be:

The groove instrument that is used for CNC milling machine of the utility model comprises knife bar, sleeve, groove pin, end cap, first spring, second spring and lock-screw; Said knife bar is processed with ladder hole vertically, and at the bottom of an end of sleeve was provided with tin, the tube bottom of sleeve was inserted in the ladder hole; Sleeve is affixed through lock-screw and knife bar; The end that said first spring is positioned at the sleeve and first spring contacted with the tube end, and said groove pin is made up of great circle shell of column, roundlet shell of column and groove head, and said great circle shell of column, roundlet shell of column and groove head fix as one successively; Said big column section is positioned at sleeve; The other end of first spring contacts with the great circle shell of column, and said second spring is installed on the roundlet shell of column and an end of second spring contacts with the great circle shell of column, is processed with centre bore on the said end cap; Said end cap passes on the openend that the roundlet shell of column is packed in sleeve, and the other end of second spring contacts with end cap.

The beneficial effect of the utility model is: first spring and second spring that the groove instrument that is used for CNC milling machine of the utility model is provided with; The groove pin can free elastic telescopic along the length direction of sleeve in sleeve; When having guaranteed groove drypoint line stressed evenly, avoided the groove head of groove pin stressed excessive and cause fracture; Because the groove pin can free elastic telescopic along the length direction of sleeve in sleeve, on inclined-plane or curved surface, during groove, guaranteed inclined-plane or curved surface graduating accuracy, improved working (machining) efficiency greatly.

Description of drawings

Fig. 1 is that the master of the groove instrument that is used for CNC milling machine of the utility model looks cutaway view.

The specific embodiment

The specific embodiment one: as shown in Figure 1; The groove instrument that is used for CNC milling machine of this embodiment comprises knife bar 1, sleeve 2, groove pin 3, end cap 4, first spring 5, second spring 6 and lock-screw 7; Said knife bar 1 is processed with ladder hole 1-1 vertically, a 2-1 at the bottom of an end of sleeve 2 is provided with tin, and the tube bottom of sleeve 2 is inserted in the ladder hole 1-1; Sleeve 2 is affixed through lock-screw 7 and knife bar 1; The end that said first spring 5 is positioned at the sleeve 2 and first spring 5 contacts with tube end 2-1, and said groove pin 3 is made up of great circle shell of column 3-1, roundlet shell of column 3-2 and groove head 3-3, and said great circle shell of column 3-1, roundlet shell of column 3-2 and groove head 3-3 fix as one successively; Said great circle shell of column 3-1 is positioned at sleeve 2; The other end of first spring 5 contacts with great circle shell of column 3-1, and said second spring 6 is installed on the roundlet shell of column 3-2 and an end of second spring 6 contacts with great circle shell of column 3-1, is processed with centre bore 4-1 on the said end cap 4; Said end cap 4 passes roundlet shell of column 3-2 and is packed on the openend of sleeve 2, and the other end of second spring 6 contacts with end cap 4.

During use with groove instrument clamping on machine tool chief axis, set the CNC milling machine program according to required groove track, then according to the CNC milling machine program of setting through groove instrument groove on workpiece.

The specific embodiment two: as shown in Figure 1, the said end cap 4 of this embodiment is threaded with the openend of sleeve 2.So design is through being threaded convenient disassembly.Other composition and annexation are identical with the specific embodiment one.

The specific embodiment three: the said groove head of this embodiment 3-3 is a carbide alloy groove head.So design, carbide alloy groove head has very high hardness and wearability, long service life.Other composition and annexation are identical with the specific embodiment one or two.
