Convenient and fast is changed to this structure, and firm in connection can not take place to become flexible in high -speed the rotation simultaneously.
Description
Technical field
The utility model relates to a kind of cutter head structure of lathe.
Background technology
Lathe, owing to completing the variation of function, often needs to change different cutter heads and carries out different patterns and the processing of precision, and therefore cutter head needs to be designed to changeable type, so just can need to change cutter head at any time according to processing.Cutter head fixed structure of the prior art is also is mostly changeable types, but it has defect is exactly for the ease of changing, its bonding strength may be affected, and may loosen under the running up of cutter head rotating shaft, and then has had influence on the machining accuracy of lathe.
Utility model content
In order to solve Problems existing in background technology, the utility model provides a kind of interchangeable cutter head structure of automatic lathe, and this structure is changed convenient and swift, is connected firmly simultaneously, can not loosens in high-speed rotation.
For achieving the above object, the utility model adopts following technical scheme:
A kind of interchangeable cutter head structure of automatic lathe, comprise rotating shaft, cutter head fixed block and cover plate, one end of described rotating shaft is connected with the output shaft of lathe motor, the other end is provided with fixed head, the both sides of fixed head are provided with vertical panel towards outer lug boss, and the centre of two lug bosses is mounting groove, and the bottom of mounting groove arranges clamping sheet, the central authorities of clamping sheet are provided with bolt hole, and two lug bosses on mounting groove top are provided with towards the projection of mounting groove; Cutter head fixed block is rectangular bulk, and its bottom center arranges stay bolt hole, and stay bolt is rotary with stay bolt in hole, and stay bolt has bolt head, and bolt head is provided with cannelure; The two bottom sides of cutter head fixed block is provided with tiltedly convex, the top of cutter head fixed block has vertical protrusion and inclined-plane, inclined-plane is provided with the screw perpendicular to inclined-plane, cutter head is arranged near vertical protrusion and is fixed by clamping piece, and clamping piece is fixed on inclined-plane by bolt; Cover plate has the profile identical with fixed head, and cover plate surrounding is provided with multiple bolt hole, and cover plate is fixed on fixed head by bolt.
Distance between described two oblique convex outsides is equal with the width of mounting groove
The beneficial effects of the utility model are: change convenient and swift, bonding strength is high, not fragile, can not loosen under running up,
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated
Fig. 1 is the schematic diagram of interchangeable cutter head structure described in the utility model;
Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and with detailed description of the invention, the utility model to be further described:
Embodiment 1
A kind of interchangeable cutter head structure of automatic lathe, as shown in Figure 1, comprise rotating shaft 1, cutter head fixed block 5 and cover plate 3, one end of rotating shaft 1 is connected with the output shaft of lathe motor, the other end is provided with fixed head 2, the both sides of fixed head 2 are provided with vertical panel towards outer lug boss 25, the centre 23 of two lug bosses 25 is mounting groove 21, the bottom of mounting groove 21 arranges clamping sheet 23, the central authorities of clamping sheet 23 are provided with bolt hole 24, and two lug bosses 25 on mounting groove 21 top are provided with towards the projection 22 of mounting groove 21.
Cutter head fixed block 5 is rectangular bulk, and its bottom center arranges stay bolt hole 53, is rotary with stay bolt 4 in stay bolt hole 53, and stay bolt 4 has bolt head 41, bolt head 41 is provided with cannelure 42.
The two bottom sides of cutter head fixed block 5 is provided with tiltedly convex 52, distance between two oblique convex outsides is equal with the width of mounting groove 21, the top of cutter head fixed block 5 has vertical protrusion 56 and inclined-plane 54, inclined-plane 54 is provided with the screw perpendicular to inclined-plane 54, cutter head 6 is arranged near vertical protrusion 56 and is fixed by clamping piece 55, and clamping piece 55 is fixed on inclined-plane 54 by bolt.
Cover plate 3 has the profile identical with fixed head 2, and its surrounding is provided with multiple bolt hole.Cover plate 3 is fixed on fixed head 2 by bolt.
The installation process of this structure is: be stuck in by cutter head fixed block 5 in mounting groove 21, then stay bolt 4 passed from the bolt hole 24 of clamping sheet 23 and be screwed into the stay bolt hole 53 bottom cutter head fixed block 5, be rotated further stay bolt, until tiltedly convex 52 of cutter head fixed block 5 hold out against with projection 22.Then cover plate 3 is bolted on fixed head 2 and namely completes.
When cutter head changed by needs, cover plate 3 of dismantling, loosers a bolt 4, cutter head fixed block 5 can be taken out, then more change jobs.
It will be recognized by those skilled in the art, under the prerequisite not departing from protection scope of the present invention, various amendment, change and combination can be carried out to above-mentioned embodiment, and think that this amendment, change and combination are within the scope of originality thought.
