Abstract
The invention belongs to machining equipment technical fields, more particularly to a kind of big times of diameter step deep hole long axis smart car turning device, including the tool apron being connect with lathe, drill holder is installed on tool apron, gland is equipped with above drill holder, carbide cutter tool bar is cased with inside drill holder, carbide cutter tool boom end is equipped with structural steel knife bar, structural steel knife bar and hard alloy knife bar using interference fit；It is connect inside the left end of structural steel knife bar with elongation bar, elongation bar is connect with cooling stick, and cooling stick runs through counterweight damping block, and counterweight damping block both ends are cased with resilient sleeve respectively, and the right end of structural steel knife bar is connect with cutter head, and cutter head end is equipped with blade.The device can the inner hole to big times of high-intensitive diameter step deep hole long axis carry out one-pass molding turning, effectively avoid the chatter mark occurred in such part process, within Ra1.6, precision does not need to carry out secondary operation to long axis inner hole the roughness of long axis inner hole within 0.02mm after processing.
Description
Technical field:
The invention belongs to machining equipment technical fields, and in particular to a kind of big times of diameter step deep hole long axis smart car turning device.
Background technique:
In machining, long axis deep hole machining is the most important thing of Machining of Shaft-type Parts, and hole depth, diameter are small, and is closed
Processing, chip removal is difficult, and difficulty of processing is big, and most knife bars using structure steel making carry out turning in industry at present, and knife bar is rigid
Property is poor, is also easy to produce deformation and vibration in process, causes part overproof.So it is long to design a kind of big times of diameter step deep hole
Axis smart car turning device is very necessary.
Summary of the invention:
The object of the present invention is to provide a kind of big times of diameter step deep hole long axis smart car turning device, which can be to the big of high intensity
The inner hole of times diameter step deep hole long axis carries out one-pass molding turning, effectively avoids the vibration occurred in such part process
Line, within Ra1.6, precision does not need to carry out two to long axis inner hole the roughness of long axis inner hole within 0.02mm after processing
Secondary processing.
The technical solution adopted by the present invention are as follows: a kind of big times of diameter step deep hole long axis smart car turning device, including connect with lathe
The tool apron connect is equipped with drill holder on the tool apron, gland is equipped with above drill holder, is cased with hard alloy inside the drill holder
Knife bar, the carbide cutter tool boom end are equipped with structural steel knife bar, and structural steel knife bar is matched with hard alloy knife bar using interference
It closes；It is connect inside the left end of the structural steel knife bar with elongation bar, the elongation bar is connect with cooling stick, and the cooling stick runs through
Counterweight damping block, counterweight damping block both ends are cased with resilient sleeve respectively, and the right end of the structural steel knife bar is connect with cutter head, knife
Cephalic par is equipped with blade.
Further, the blade is diamond shape, and angle is 80 °, and relief angle is 0 °, and with a thickness of 4.76mm, the angle R is 0.2mm, material
Material is hard alloy.
Beneficial effects of the present invention: a kind of big times of diameter step deep hole long axis smart car turning device is provided, which can be to height
The inner hole of big times of diameter step deep hole long axis of intensity carries out one-pass molding turning, effectively avoids going out in such part process
Existing chatter mark, within Ra1.6, precision does not need within 0.02mm to long axis inner hole the roughness of long axis inner hole after processing
Secondary operation is carried out, structure is simple, and design is rationally, low in cost, and it is economic and practical, it is easy to promote and use on a large scale.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of embodiment one；
Fig. 2 is the partial structural diagram of A in Fig. 1.
Specific embodiment:
Embodiment one
Referring to Figures 1 and 2, a kind of big times of diameter step deep hole long axis smart car turning device, it is described including the tool apron 1 being connect with lathe
Drill holder 2 is installed on tool apron 1, gland 3 is equipped with above drill holder 2, is cased with carbide cutter tool bar 4, institute inside the drill holder 2
It states 4 end of hard alloy knife bar and structural steel knife bar 5, structural steel knife bar 5 and hard alloy knife bar 4 is installed using interference fit；
It is connect inside the left end of the structural steel knife bar 5 with elongation bar 6, the elongation bar 6 is connect with cooling stick 7, and the cooling stick 7 passes through
Counterweight damping block 8 is worn, 8 both ends of counterweight damping block are cased with resilient sleeve 9, the right end and cutter head of the structural steel knife bar 5 respectively
10 connections, 10 end of cutter head are equipped with blade 11.
Embodiment two, on the basis of one technical solution of embodiment, the blade 11 is designed as diamond shape, and angle is
80 °, relief angle is 0 °, and with a thickness of 4.76mm, the angle R is 0.2mm, and material is hard alloy.
According to embodiment 1 or big times of diameter step deep hole long axis smart car turning device as described in example 2, in turning due to knife
Bar is too long, can generate larger vibration, and the present invention is cooperated by the elongation bar, counterweight damping block and resilient sleeve, and vibration is existed
Digestion, guarantees the finish of piece surface inside device.
