Abstract
The utility model relates to a milling cutter, in particular to a milling cutter with a replaceable cutter bit. The milling cutter comprises a cutter body, the cutter bit and a cutting edge, the cutting edge is arranged on the cutter bit, a groove is disposed at the front end of the cutter body, more than two clamping blocks are arranged in the groove, a through hole is disposed between the cutter body and the groove, and screwing devices are arranged in the through hole and connected with the clamping blocks. After the structure is adopted, the milling cutter with the replaceable cutter bit has the advantages that the quantity of milling cutters can be reduced, production cost is lowered, and machining efficiency is improved.
Description
Technical field
The utility model relates to a kind of milling cutter, the milling cutter that particularly a kind of cutter head can change.
Background technology
Milling cutter is the most frequently used machining tool in the process of workpiece, so the quality of milling cutter is very important to the processing of workpiece.Workpiece is being added man-hour, sometimes because the structural requirement of workpiece self adopts different milling cutters.So just need in the process of processing, change milling cutter again, because the price of milling cutter self will inevitably make production cost increase.If the cutter head of milling cutter can be changed, just do not want diversified milling cutter, only need milling cutter tip miscellaneous just passable.Add man-hour, only need milling cutter tip be fixed in the milling cutter body and get final product.
Summary of the invention
The utility model technical issues that need to address provide the milling cutter that a kind of cutter head can change.
For solving above-mentioned technical problem, the interchangeable milling cutter of the cutter head of the utility model comprises cutter hub, cutter head and cutting edge, and said cutting edge is arranged on the cutter head, and said cutter hub front end has groove, is provided with plural grip block in the said groove; Have through hole between said cutter hub and the groove; But be provided with winding device in the said through hole, but said winding device links to each other with grip block.
But said winding device is a through-hole wall is provided with screw thread, has the screw rod that is complementary with screw thread to pass through hole; One end of said screw rod is fixedly connected with grip block, and the other end of said screw rod is provided with the polygon projection.
But said winding device has the handle of screwing that adapts with it, and an end of the said handle of screwing has the polygon groove that is complementary with the polygon projection.
Said grip block is three, is evenly distributed on the tangent plane circumference of groove.
The clamping end face of said grip block is provided with salient point.
After adopting said structure, the interchangeable milling cutter of the cutter head of the utility model can reduce the quantity of milling cutter, has reduced production cost, has improved working (machining) efficiency.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
But Fig. 2 is the structural representation of the utility model winding device.
Among the figure: 1 is cutter hub, and 2 is grip block, and 3 is screw rod, and 4 is groove
The specific embodiment
The interchangeable milling cutter of cutter head as depicted in figs. 1 and 2 comprises cutter hub 1, cutter head and cutting edge; Said cutting edge is arranged on the cutter head; It is characterized in that: said cutter hub 1 front end has groove 4; Be provided with plural grip block 2 in the said groove 4, clamp cutter head through the grip block 2 that is distributed on groove 4 circumference like this.Have through hole between said cutter hub and the groove 4; But be provided with winding device in the said through hole, but said winding device link to each other with grip block 2, but winding device be used for adjusting the distance between grip block 2 and the cutter hub 1, make grip block 2 well fix cutter head.
But said winding device is a through-hole wall is provided with screw thread, has the screw rod 3 that is complementary with screw thread to pass through hole; One end of said screw rod 3 is fixedly connected with grip block 2, and the other end of said screw rod 3 is provided with the polygon projection, the polygonal projection grip block 2 that helps to screw.
But said winding device has the handle of screwing that adapts with it, and an end of the said handle of screwing has the polygon groove that is complementary with the polygon projection, rotary handle is enclosed within the grip block 2 of just can screwing on the polygon projection clamps cutter head.When needing tool changing, as long as through rotary handle screw rod 3 is screwed out from through hole, becoming flexible will appear in cutter head like this, and cutter head is taken out from through hole, changes other cutter head and fixes and get final product.
Said grip block 2 is three, is evenly distributed on the tangent plane circumference of groove, can better fix cutter head like this.
The clamping end face of said grip block 2 is provided with salient point, like this can be better fixing cutter head.
Certainly, but described winding device can change the device of other uses into, and the quantity of grip block 2 also can be more than 3, and such conversion all drops within the scope of the utility model protection.
Claims (5)
1. the interchangeable milling cutter of cutter head comprises cutter hub, cutter head and cutting edge, and said cutting edge is arranged on the cutter head, it is characterized in that: said cutter hub front end has groove, is provided with plural grip block in the said groove; Have through hole between said cutter hub and the groove; But be provided with winding device in the said through hole, but said winding device links to each other with grip block.
2. according to the interchangeable milling cutter of the described cutter head of claim 1, it is characterized in that: be provided with screw thread but said winding device is a through-hole wall, have the screw rod that is complementary with screw thread to pass through hole; One end of said screw rod is fixedly connected with grip block, and the other end of said screw rod is provided with the polygon projection.
3. according to the interchangeable milling cutter of the described cutter head of claim 2, it is characterized in that: but said winding device has the handle of screwing that adapts with it, and an end of the said handle of screwing has the polygon groove that is complementary with the polygon projection.
