Abstract
The invention relates to a guide device for nuclear power driving pipe seat deep hole machining, which comprises a shaft sleeve and a bush. A workpiece is tightly sheathed at one end of the shaft sleeve. The bush is arranged in the other end of the shaft sleeve. An oil seal is arranged between contact surfaces of the shaft sleeve and the workpiece. A drill bit is inserted into the bush for guide machining. A tightening bolt is arranged on the shaft sleeve. By using the guide device, effective guide can be realized, the problems of deviation and vibration which are apt to occur during machining are solved, the deep hole machining quality and the machining progress are guaranteed, the requirements on product size accuracy and surface roughness are satisfied, the problems of great chip removal difficulty, poor heat dissipation effect and the like are solved, and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of nuclear power and drive the frock clamp that the base deep hole machining is used, refer more particularly to the guider of using when processing drives the base deep hole.
Background technology
In the application of advanced Nuclear Power product, deep hole machining is different from the processing of general hole, and deep hole machining is than greater than 10 processing to the diameter in the length in hole and hole.General deep hole is aspect ratio L/d 〉=100 in most cases.Such as the axial oilhole of oil har opening, axle, gun tube of rocket bomb body and various cannons etc.The deep hole machining difficulty is high, and labor content is large, is the key operation in the machining.
For adapting to the deep hole machining of the new engineering material that kind is more and more many, difficulty of processing is more and more high, the method for deep hole machining develops into unconventional Cutting Process method by traditional cutting working method.Axis at the deep hole machining mesopore is easily crooked, this is that strength and stiffness are poor because deep hole tools is thinner, draws easily partially and vibration in the processing, also have cutter cooling heat dissipation condition poor, the chip discharge difficulty, knife bar is subjected to the restriction in aperture, and diameter is little, length is large, cause poor rigidity, easily produce vibration, ripple, tapering during the low cutting of intensity, and affect the linearity of deep hole and surface roughness etc.
Summary of the invention
Drive the problem that exists in the base deep hole machining process for solving above-mentioned nuclear power, the applicant designs a kind of nuclear power and drives the guider that the base deep hole machining is used, and namely nuclear power drives the guider of base deep hole machining.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of nuclear power drives the guider of base deep hole machining, comprises axle sleeve and lining, and axle sleeve one end cover clamping of workpieces arranges lining in the other end of axle sleeve, and axle sleeve arranges oil sealing with the end face that contacts of workpiece; Drill bit inserts the processing of leading in the lining; Arrange on the axle sleeve and tight a bolt.
This device is fixed on the machine tool chief axis when installing, and selects suitable lining according to the size of driving base deep hole to be processed, and selected suitable lining is inserted in the axle sleeve, confirms whether lining is in place; Check that oil sealing has or not breakage, confirm without after the breakage, axle sleeve is installed on the machine tool chief axis, then workpiece is installed in the axle sleeve, guarantee workpiece end face and oil sealing close contact and oil-proof; Tight a bolt, guarantee the axle sleeve clamping work pieces, drill bit carries out Drilling operation under the guide effect of lining.
The invention has the beneficial effects as follows: the application of the invention, can realize effective guiding, solved incidental drawing partially and vibration problem in the process, thereby solved in the easy crooked problem of the axis of deep hole machining mesopore.Guaranteed deep hole machining quality and processing progress, guaranteed the requirement to product size precision and surface roughness, reliability is high.Can also solve in process, occur collapse the difficult problems such as cutter and chip removal difficulty weak heat-dissipating, and this invention is installed, convenient disassembly, can manual adjustments, flexibility is very good, has greatly improved production efficiency.
Description of drawings
The present invention has accompanying drawing two width of cloth.
Fig. 1 is front view of the present invention,
Fig. 2 is side view of the present invention.
Among the figure: 1, workpiece, 2, axle sleeve, 3, oil sealing, 4, lining, 5, drill bit, 6, bolt.
The specific embodiment
Specify the present invention below in conjunction with embodiment.
Shown in Fig. 1 ~ 2, nuclear power provided by the invention drives the guider of base deep hole machining, comprises axle sleeve and lining, and axle sleeve one end cover clamping of workpieces arranges lining in the other end of axle sleeve, and axle sleeve arranges oil sealing with the end face that contacts of workpiece; Drill bit inserts the processing of leading in the lining; Arrange on the axle sleeve and tight a bolt.This device is fixed on the machine tool chief axis when installing, and selects suitable lining according to the size of driving base deep hole to be processed, and selected suitable lining is inserted in the axle sleeve, confirms whether lining is in place; Check that oil sealing has or not breakage, confirm that oil sealing is without breakage after, axle sleeve is installed on the machine tool chief axis, then workpiece is installed in the axle sleeve, guarantee workpiece end face and oil sealing close contact and oil-proof; Tight a bolt, guarantee the axle sleeve clamping work pieces, drill bit carries out Drilling operation under the guide effect of lining.
Through facts have proved, the nuclear power of processing with this device drives the base deep hole, and to have process technology reliable, and process is stable, and practical, high reliability has guaranteed the quality of production of this product well, and is final, reaches client's satisfaction.
The present invention is not limited to above-described embodiment, and protection scope of the present invention is all classified in any equivalent concepts or change in the technical scope that the present invention discloses as.
