Abstract
The utility model provides a special machine for drilling four holes in a bearing sleeve. The special machine comprises a lathe bed, a power device and drilling bits. The special machine is characterized in that a drilling template is fixedly connected to the lathe bed, wherein, a core shaft hole and the four holes are formed on the drilling template; drilling sleeves are arranged in the four holes; a fixed core shaft is mounted in the core shaft hole in a penetrating manner; a screw rod is arranged at one end part of the core shaft and connected with a pressure plate through a nut; a backing plate stuck to the drilling template is arranged at the same time; a core shaft penetrating hole is formed on the backing plate; and a chip removing slot is formed on the periphery of the backing plate. A four-hole drilling template positioning manner is adopted, and the four holes are processed at the same time, so that the accuracy of forms and positions is guaranteed, the production efficiency is improved and the labor intensity is reduced.
Description
Technical field
The utility model belongs to a kind of machining equipment, particularly a kind ofly is used for the special equipment that the automotive axle bearing holder (housing, cover) is processed four holes. and it can improve four hole site precision, reduces labor intensity, and boosts productivity.
Background technology
Using four holes of machine tooling bearing holder (housing, cover) at present, is the technology that adopts positioning of rotating, single hole processing, and shortcoming is that positioning accuracy is poor, and labour intensity is big, and production efficiency is low.
Summary of the invention
The purpose of the utility model provides a kind of bearing holder (housing, cover) and bores four hole special machines, adopts four hole drill Template Location, and four holes process simultaneously, guarantees the accuracy of form and position, enhances productivity, and has alleviated labour intensity.
The purpose of the utility model realizes through following technical scheme: it comprises lathe bed, power set, drill bit, it is characterized in that: on lathe bed, be fixedly connected bushing plate, mandrel hole and four holes are set on the bushing plate; In four holes, drill bushing is set, installs fixing mandrel in the mandrel hole, the end of mandrel is provided with screw rod; Connect pressing plate through nut; The backing plate that is affixed on bushing plate is set simultaneously, and backing plate is provided with the mandrel perforation, and periphery has chip area.
The good effect of the utility model is: adopt four hole drill Template Location, four holes process simultaneously, guarantee the accuracy of form and position, enhance productivity, and have alleviated labour intensity.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 bores four hole localization part structural representations.
Fig. 3 is the right view of Fig. 2.
Component serial number among the figure: power set 1, drill bit 2, bushing plate 3, lathe bed 4, mandrel 5, drill bushing 6, workpiece 7, pressing plate 8, backing plate 9, chip area 9-1.
The specific embodiment
See Fig. 1-3, concrete structure is following: on lathe bed 4, press four drill bits 2 that prior art is assembled power set 1 and passed through its drive.On lathe bed 4, be fixedly connected bushing plate 3; Mandrel hole and four holes are set on the bushing plate 3, drill bushing 6 is set in four holes, install fixing mandrel 5 in the mandrel hole; The end of mandrel 5 is provided with screw rod; Connect pressing plate 8. through nut the backing plate 9 that is affixed on bushing plate is set simultaneously, backing plate 9 is provided with the mandrel perforation, and periphery has chip area 9-1.
During use, power set 1 drive four drill bits 2, through the drill bushing on the bushing plate 36, workpiece 7 are carried out the processing of four holes simultaneously, and workpiece 7 relies on bushing plate 3, mandrel 5 to position, and pressing plate 8 clamps, thereby obtains machining accuracy.
