Abstract
The invention provides a method for processing slewing bearing roller paths and a double-tool rest. The method comprises the steps as follows: two slewing bearing blanks are superposed and clamped on a vertical lathe from top to bottom, wherein both the degree of parallelism of an upper end face and a lower end face and the thickness tolerance of the slewing bearing blanks meet the technological requirements; two lathe tools which are arranged on the same tool rest are applied to processing the roller paths on both the upper and the lower blanks respectively. By adopting the method for processing slewing bearing roller paths disclosed by the invention, the efficiency of processing roller paths can be doubled and the consistency of the slewing bearing roller paths can be increased greatly on condition that the existing equipment is hardly modified; in addition, the double-tool rest disclosed by the invention is special for the method for processing slewing bearing roller paths, therefore, the double-tool rest also has the beneficial effect that the efficiency of processing the roller paths is doubled.
Description
Technical field
The present invention relates to engineering machinery field, particularly a kind of pivoting support raceway processing method and double-pole frame,
Background technology
The processing of pivoting support raceway turning at present generally once can only be processed a workpiece, and working (machining) efficiency is low, and equipment needed thereby, place are dropped into many, causes fund, manpower, device resource waste.Because pivoting support is the main pivoting part of engineering machinery, wind power equipment, the deficiency of production capacity can have a strong impact on the development of engineering machinery, wind-powered electricity generation industry.Therefore, need a kind of new processing method in a hurry, on the limited basis of equipment, improve the working (machining) efficiency of pivoting support, guarantee good quality simultaneously.
Summary of the invention
In view of this, the present invention is intended to propose a kind of pivoting support raceway processing method, on the limited basis of equipment, significantly improves working (machining) efficiency, and guarantees good crudy.
For achieving the above object, technical scheme of the present invention is achieved in that
A kind of pivoting support raceway processing method; With two thickness deviations and the upper and lower end face depth of parallelism all the pivoting support blank of according with process requirements superpose clamping up and down on vertical lathe, simultaneously two blanks are up and down carried out raceway processing respectively with two lathe tools that are contained on the same knife rest.
Further, saidly two blanks are up and down carried out the program of raceway processing and blank to single pivoting support respectively to carry out the program that raceway processes consistent.
Further, all downward order stack of the datum level of said two blanks up and down installs additional and is clipped on the said vertical lathe.
Another object of the present invention is to propose a kind of double-pole frame; Comprise the knife rest main body that is used for mounting cutter and be used for the knife rest main body is installed to the positioning cylinder on the lathe; Said knife rest main body is provided with the first cutter installation position and the second cutter installation position that is parallel to each other, and the said first cutter installation position is with in the said second cutter installation position is arranged on the same plane vertical with said knife rest main body.
Further, the said second cutter installation position is the open slot that is provided with on the said knife rest main body, and said open slot is parallel with the said first cutter installation position.
Further, be provided with a plurality of screws that are used for fixing cutter in the part between the first cutter installation position and the second cutter installation position on the said knife rest main body.
With respect to prior art, the present invention has following advantage: pivoting support raceway processing method of the present invention is not done under the prerequisite of change at existing equipment basically, can the raceway working (machining) efficiency be doubled, and can significantly improve the uniformity of pivoting support raceway; And double-pole frame of the present invention is exclusively used in above-mentioned pivoting support raceway processing method, therefore also has the beneficial effect that the raceway working (machining) efficiency is doubled.

The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the present invention can make up each other.Below with reference to accompanying drawing and combine embodiment to specify the present invention.
Pivoting support raceway processing method of the present invention be with two thickness deviations and the upper and lower end face depth of parallelism all the pivoting support blank of according with process requirements superpose clamping up and down on vertical lathe; Two lathe tools with being contained on the same knife rest carry out raceway processing respectively to two blanks up and down simultaneously, so just can the raceway working (machining) efficiency be doubled.Detailed process is following:
When blank is rough turn before the raceway manufacturing procedure according to technological requirement; The depth of parallelism of control blank thickness tolerance and upper and lower end face; Then on vertical lathe to the workpiece centering that superposes, require circle jumping degree≤0.15mm, the mode of stack is as shown in Figure 1; The datum level of workpiece I, II is downward, superposes in order, centering.After folding workpiece, workpiece is fixed, press-fits process and will prevent that the workpiece play from causing processing defective, make full use of the vertical lathe four paws.After clamping workpiece is accomplished,, add man-hour through programming, set cutting line according to the operating process operation of numerical control vertical lathe; Use special-purpose double-pole frame, the knife rest of two lathe tools promptly is housed simultaneously, call the raceway program of single-piece work; Operation just can be accomplished the two part raceway processing of pivoting support; Move a secondary program at same vertical lathe, can once accomplish the processing of two pivoting support workpiece, and the consistent size of two workpiece raceways.Owing to the knife rest that adopts special use, two lathe tools of while clamping, thus can guarantee the raceway correctness of symmetry assurance rolling element contact angle in raceway of circular arc up and down, easy to implement the method, reliable in quality.
Fig. 2 to Fig. 5 is the relevant drawings of above-mentioned double-pole frame; Shown in figure; This double-pole frame comprises the knife rest main body that is used for mounting cutter and is used for the knife rest main body is installed to the positioning cylinder 1 on the lathe that the knife rest main body is provided with the first cutter installation position 3 and the second cutter installation position 2 that is parallel to each other, and the first cutter installation position 3 is in the vertical same plane of knife rest main body with 2 settings of the second cutter installation position; The second cutter installation position 2 is for being provided with the open slot on the knife rest main body; Therefore this open slot is parallel with the first cutter installation position 3, is provided with nine screws 4 that are used for fixing cutter in the part between the first cutter installation position 3 and the second cutter installation position 2 on the knife rest main body, two cutters of clamping firmly; Guarantee the positioning accuracy of lathe tool, satisfy the pivoting support raceway processing request.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
