Summary of the invention

The purpose of the utility model is the deficiency to prior art, and a kind of simple in structure, milling head that action has the automatic indexing function accurately is provided.

The purpose of the utility model realizes through following technical scheme:

A kind of milling head with automatic indexing function; Comprise the milling head seat, vertically be arranged in vertical drive shaft on the milling head seat, can rotate and can be arranged at movably vertically revolving sleeve on the milling head seat, be fixedly set in main shaft housing, horizontal main axis, automatic indexing mechanism and the automatic loading and unloading cutter mechanism of horizontal arrangement on the main shaft housing on the revolving sleeve around vertical drive shaft; It is characterized in that: said automatic indexing mechanism comprises the oil cylinder that is arranged on the milling head seat, be fixedly installed in fixed gear on the vertical drive shaft, be fixedly installed in the free gear that can be meshed with fixed gear on the revolving sleeve, be fixedly installed in fixed gear plate on the milling head seat, be fixedly installed in the movable fluted disc that can be meshed with fixed gear plate on the oil cylinder piston body; The piston body of said oil cylinder is fixedly connected with revolving sleeve and but the driving rotational cover vertically moves between rotary position and fixed position; When revolving sleeve is in rotary position, fixed gear is meshed with free gear, fixed gear plate separates with movable fluted disc; When revolving sleeve is in a fixed position, fixed gear separates with free gear, fixed gear plate is meshed with movable fluted disc.

Further, said automatic loading and unloading cutter mechanism, comprise the interior push rod that is movably set in the main shaft, be arranged in the push rod front end pulling claw, be sheathed on the push rod butterfly spring, connect push rod in driving along main shaft moves axially and disk spring shrinks oil cylinder.

Further, said main shaft housing is connected with revolving sleeve through Connection Block, is provided with bearing block in the Connection Block, and bearing block is provided with the bearing that matches with vertical drive shaft.

The utlity model has following beneficial effect:

Automatic indexing mechanism adopts oil cylinder, fixed gear, free gear, fixed gear plate and movable fluted disc; The moving up and down of oil cylinder piston body can drive free gear, movable fluted disc and revolving sleeve and move simultaneously; Be arranged to when fixed gear and free gear engagement; Fixed gear plate separates with movable fluted disc; Fluted disc is used to realize the fixing of revolving sleeve, and gear is used for then the transmission of power of vertical drive shaft is realized the revolution of revolving sleeve to revolving sleeve that both match and can realize the accurate adjustment of revolving sleeve angle of revolution; Adopt the automatic loading and unloading cutter mechanism, can realize the quick replacing of milling cutter.

Description of drawings

Below in conjunction with accompanying drawing the utility model is done further explain.

Fig. 1 is the structural representation of the utility model.

The specific embodiment

With reference to shown in Figure 1; A kind of milling head with automatic indexing function; Comprise milling head seat 1, vertically be arranged in vertical drive shaft 8 on the milling head seat 1, can rotate and can be arranged at movably vertically revolving sleeve 2 on the milling head seat 1, be fixedly set in main shaft housing 4, horizontal main axis 6, automatic indexing mechanism and the automatic loading and unloading cutter mechanism of horizontal arrangement on main shaft housing 4 on the revolving sleeve 2 around vertical drive shaft 8; Main shaft housing 4 is connected with revolving sleeve 2 through Connection Block 3; Be provided with bearing block 5 in the Connection Block 3, bearing block 5 is provided with the bearing 51 that matches with vertical drive shaft 8, passes through

bevel gear

81,61 mutual transmissions between vertical drive shaft 8 and the main shaft 6.

Automatic indexing mechanism comprises the oil cylinder that is arranged on the milling head seat 1, be fixedly installed in fixed gear 95 on the vertical drive shaft 8, be fixedly installed in the free gear 94 that can be meshed with fixed gear 95 on the revolving sleeve 2, be fixedly installed in fixed gear plate 91 on the milling head seat 1, be fixedly installed in the movable fluted disc 92 that can be meshed with fixed gear plate 91 on the oil cylinder piston body 93; The piston body 93 of oil cylinder is fixedly connected with revolving sleeve 2 and but driving rotational cover 2 vertically moves between rotary position and fixed position; Being provided with spring 96 in the oil cylinder is used to make piston body 93 to descend fast; When needs adjustment main shaft 6 angles, the piston body 93 of oil cylinder moves down, and makes revolving sleeve 2 be moved downward to rotary position; At this moment fixed gear 95 is meshed with free gear 94, fixed gear plate 91 separates with movable fluted disc 92; Vertical drive shaft 8 slowly rotation driving rotational cover 2 rotates, and when reaching the target location, the piston body 93 of oil cylinder moves up; Make revolving sleeve 2 be moved upward to the fixed position; At this moment fixed gear 95 separates with free gear 94, fixed gear plate 91 is meshed with movable fluted disc 92, and revolving sleeve 2 is fixing, accomplishes the revolution action.

The automatic loading and unloading cutter mechanism, comprise the interior push rod 72 that is movably set in the main shaft 6, be arranged in push rod 72 front ends pulling claw 71, be sheathed on the push rod 72 butterfly spring 73, connect in driving push rod 72 along the oil cylinder 74 that main shaft 6 moves axially and disk spring 73 shrinks, when tool changing; Push rod 72 moved forward and disk spring 73 compressions in oil cylinder 74 drove; At this moment pulling claw 71 unclamps, and takes off old cutter, then the handle of a knife 7 of new milling cutter is put into pulling claw 71; Under the elastic force effect of oil cylinder 74 and disk spring 73; Interior push rod 72 moves backward, and pulling claw 71 clamps the handle of a knife 7 of milling cutter, accomplishes the tool changing action.

The above; Be merely the utility model preferred embodiment; So can not limit the scope that the utility model is implemented with this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
