Abstract
The utility model provides a slewing bearing deep hole processing device for a through hole with the length-diameter ratio thereof greater than seven, wherein the processing method is modified and auxiliary equipment is additionally provided. Due to the adoption of the device, after one side of the through hole is drilled and positioned through a positioning pin, the other side of the through hole is docked and drilled. Therefore, the length-diameter ratio of a drill bit is reduced and the rigidity of the drill bit is improved. Meanwhile, during the processing procedure, chips are smoothly removed and the drill bit is not easily broken. Processed hole walls are good in smoothness and the diameters of processed holes are unified. The work efficiency and the precision of a numerical control high-speed drill are fully improved. The quality of products is ensured and the production efficiency is increased. The slewing bearing deep hole processing device comprises a workpiece, a positioning pin, a backing plate, a first compression bolt, a first compression nut, a second compression bolt, a second compression nut, a pressing plate and a support. The backing plate is arranged on the workbench of a machine tool. A circular ring-shaped workpiece is arranged on the backing plate. The workpiece and the backing plate are equipped with prepared holes correspondingly. The positioning pin is arranged inside the prepared holes. The slewing bearing deep hole processing device is simple in structure and convenient in operation. Due to the adoption of the device, the butt joint of deep holes can be easily realized and the requirement of the position accuracy of the holes is satisfied. The slewing bearing deep hole processing device is scientific, efficient, accurate and practicable.
Description
Technical field
The utility model relates to deep hole drilling apparatus, especially a kind of pivoting support deep hole drilling apparatus.
Background technology
At present, pivoting support is a kind ofly can bear the large size bearing of axial load, radial load and tilting moment simultaneously, generally on its lasso, all carries installing hole, is connected on the respective hosts through bolt.Therefore the processing of installing hole is just extremely important, and the position degree of installing hole correctly is the most important condition that guarantees that bearing is installed.The processing of now general pivoting support installing hole all is to adopt plain radial drilling machine line boring; Hole location is poor, hole wall is coarse, also can cause during drilling deep hole the hole to tilt, and chip removal difficulty during drilling deep hole, causes drill bit to fracture easily; Hole wall scratches, and whole efficiency is on the low side.For solving the difficulty of this class bearing deep hole machining, to enhance productivity, special method-rendezvous method of exploring a kind of high-efficiency high-quality satisfies production requirement.For the hole of draw ratio greater than 7 times, generally be difficult to numerical control and directly be drilled to, even in draw ratio during greater than 10 times, the rigidity of drill bit a little less than, can not carry out digital control processing.The method can make full use of the efficient and high characteristic of precision that High-speed CNC is bored, and not only guarantees the quality of product but also improved production efficiency.Be particularly suitable for the processing of large-size pivoting support end face deep hole
The utility model content
The purpose of the utility model is in order to overcome deficiency of the prior art, a kind of pivoting support deep hole drilling apparatus to be provided, for draw ratio greater than 7 through hole; Through changing processing mode, increase servicing unit, adopt a hole drill to locate with alignment pin the back well; The another side opposite bore reduces the draw ratio that adds used drill bit in man-hour, and the drill bit rigidity strengthens; It is smooth and easy to add the chip removal in man-hour, frangible not, and the hole wall fineness that processes is good; The aperture is unified, can fully improve work efficiency and precision that High-speed CNC is bored, guarantees the quality of product and has improved production efficiency.
The utility model adopts following technical scheme to achieve these goals: a kind of pivoting support deep hole drilling apparatus is by workpiece, alignment pin, and backing plate, first hold-down bolt and nut, second hold-down bolt and nut, pressing plate supports and constitutes; The top of platen is provided with backing plate, and the top of backing plate is provided with the workpiece of annular, and the corresponding reservation with backing plate of workpiece is porose, and alignment pin is set in the hole;
The corresponding reservation with platen of one side of backing plate is porose, and first hold-down bolt and nut are set in the hole; Backing plate inboard on the platen is provided with support, and the upper end of support is provided with pressing plate on the convexity of workpiece inboard; Corresponding preformed hole on the platen of pressing plate and below is provided with second hold-down bolt and nut in the hole.
The operation principle of the utility model is: 1. backing plate is positioned on the numerically controlled machine, fixes through hold-down bolt and nut; Institute's processing work is put on the backing plate, through hold-down bolt and nut and pressing plate, support fixation.The machining hole degree of depth is at least 1/2 of total length.
2. take off behind the workpiece hole of boring three, same diameter sizes corresponding at the fixing backing plate of correspondence, as the dowel hole behind the workpiece turn-over with position of mounting hole.
3. be not more than the alignment pin of 0.03mm with the gap, the workpiece behind the turn-over of having good positioning, the program processing by 1 step drills through connecting hole.
The beneficial effect of the utility model is: simple in structure, easy to operate, can accomplish the butt joint of deep hole through the method easily, and satisfy the position degree requirement in hole.This device and processing method are applicable to draw ratio greater than 7 large-size pivoting support through hole digital control processing, and the hole be circumference array be uniformly distributed with or the hole with the center line symmetry, instructions for use all can be satisfied in the position of mounting hole degree, the aperture that process.
Implement checking: through bearing 130.55.1647.03 outer ring installing hole is processed, the aperture is φ 36, hole depth 402, draw ratio 402/36=11.17; Process the A face earlier by scheme, drilling depth is 210, and turn-over drills through behind the location.Measure and know: double-edged hole location all is not more than 0.10mm, meets design requirement; Highly polished in the hole, there is not the phenomenon of scuffing, all can pass through smoothly by straight school rod, explain that the concentricity of butt hole overlaps.The scientific and efficient of this scheme and device, accurate feasibility have been verified.
