Abstract
The utility model discloses a high-strength long cantilever cutter bar, which comprises a hard alloy rod 1, a steel component rod 2 and a bolt 3. The hard alloy rod 1 and the steel component rod 2 adopt a dovetail groove positioning mode. When the diameter of the cutter bar is less than or equal to 18mm, the position of a dovetail groove is connected and fastened in a welding mode. When the diameter of the cutter bar is more than 18mm, the vertical direction of the dovetail groove is connected and fastened by the bolt 3. According to the specific service condition, firstly the positioning and installing mode of a cutter head of the steel component rod 2 can be processed, and then the positioning and installing mode of the hard alloy rod 1 and a machine tool cutter holder or a cutter handle can be processed. The utility model can realize to carry out turning, drilling, boring and milling processing on the screw threads at the positions of a slender valve hole, an inner groove and a deep hole of which the length-diameter ratios can reach 25 times on the lathe, the milling machine, the boring machine and the processing center. The high-strength long cantilever cutter bar has the advantages of safety, reliability, simple structure and low cost.
Description
Technical field
The utility model relates to a kind of long cantilever knife bar, particularly a kind of high-strength and long cantilever knife bar.
Background technology
On some valve body and similar parts, place's screw thread is processed always comparatively difficulty, particularly some elongated valve openings, internal channel, deep hole place screw thread in the valve opening that draw ratio is bigger, internal channel, the deep hole.The employing steel knife bar manufacturing that common knife bar has, the employing high-speed steel manufacturing that has, but the quality of processing be difficult for to guarantee that all working (machining) efficiency is also low reach valve opening, internal channel, deep hole place screw thread more than 15 times for draw ratio, then can not process basically.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of high-strength and long cantilever knife bar, can be implemented in that lathe, milling machine, boring machine, machining center are got on the bus, brill, boring, Milling Process draw ratio can reach 25 times elongated valve opening, internal channel, deep hole place screw thread.
The utility model is to constitute like this:
Cemented carbide 1 is connected with steel component bar 2, interface mode adopts the dove-tail locate mode, when the knife bar diameter is less than or equal to 18mm, adopting welding manner to connect at the dovetail groove place tightens up, when knife bar diameter during, tighten up with screw 3 connected modes in the vertical direction of dovetail groove greater than 18mm.
Cemented carbide 1 can at first be processed the cutter head location and installation mode of steel component bar 2 according to concrete operating position with after steel component bar 2 is connected, secondly the location and installation mode of processing rigid rod of metal alloy 1 and lathe tool rest or handle of a knife.
The utility model is simple in structure, and is reliable, and cost is low, can be implemented in that lathe, milling machine, boring machine, machining center are got on the bus, brill, boring, Milling Process draw ratio can reach 25 times elongated valve opening, internal channel, deep hole place screw thread.
Description of drawings
Structural representation when Fig. 1 directly is less than or equal to 18mm for the utility model bar straight knife
Fig. 2 is the structural representation of the utility model knife bar diameter during greater than 18mm
The specific embodiment
Cemented carbide 1 is connected with steel component bar 2, cemented carbide 1 has two kinds with the connected mode of steel component bar 2, when the knife bar diameter is less than or equal to 18mm, adopt welding manner to connect, when knife bar diameter during greater than 18mm, adopt screw 3 radially to connect, interface mode all adopts the dove-tail locate mode.
Cemented carbide 1 is with after steel component bar 2 is connected, this knife bar can be according to actual needs, steel component bar 2 is processed the back corresponding cutter head of installation to be satisfied, on the mounting means of knife bar, according to the specific requirement of using lathe, can adopt spring clip cover clamping or be directly installed on the handle of a knife or after further processing, directly to be contained on the lathe tool rest with cemented carbide 1.
Claims (2)
1. high-strength and long cantilever knife bar, comprise cemented carbide and steel component bar, it is characterized in that: cemented carbide (1) is connected with steel component bar (2), connecting the back knife bar can be according to concrete operating position, at first process the cutter head location and installation mode of steel component bar (2), secondly the location and installation mode of processing rigid rod of metal alloy (1) and lathe tool rest or handle of a knife.
2. a kind of high-strength and long cantilever knife bar according to claim 1, it is characterized in that: cemented carbide (1) has two kinds with the connected mode of steel component bar (2), when the knife bar diameter is less than or equal to 18mm, adopt welding manner to connect, when knife bar diameter during greater than 18mm, adopt screw (3) radially to connect, interface mode all adopts the dove-tail location.
