Abstract
The utility model provides a device for boring a slotted hole of an eccentric shaft. The device comprises a shaft sleeve seat and an eccentric shaft sleeve mounted on the shaft sleeve seat and accommodated in two through-holes formed on the shaft sleeve seat, wherein a rotary processing shaft is accommodated inside the eccentric shaft sleeve, a cutter is arranged at the front end of the rotary processing shaft and used for boring a slotted hole, a driving wheel is fixedly connected with one end of the eccentric shaft sleeve, and the driving wheel drives the eccentric shaft sleeve to rotate around the axes of the through-holes; and a first rotating bearing, a snap ring, a spring and a second rotating bearing are connected in sequence to the eccentric shaft sleeve and in the position between the two through-holes of the shaft sleeve seat. The device has a simple structure, is smart and applicable, improves the accuracy of boring slotted holes of spring hinges, and is a practical device for automatic production of spring hinges.
Description
Technical field
The utility model relates to the component of machine manufacture field, especially the catapult shell is carried out the device or the structure in slot boring hole.
Background technology
Picture frame on the glasses can adopt the catapult shell to be connected with the active connection place between the mirror leg, and the profile work in-process of catapult shell need be used slot boring hole operation, promptly the catapult shell is carried out the reaming action in slot boring hole, makes the catapult shell meet specification requirement; Before this, this work is finished by operation manually mostly, not only wastes time and energy, and has directly influenced the production efficiency of catapult shell, is unfavorable for the automation that the catapult shell is produced; Thereby be necessary further to be improved on this basis.
The utility model content
The purpose of this utility model is for the precision that improves catapult shell slot boring hole and the slotted eye pore size rationally is set, and a kind of eccentric shaft slot boring aperture apparatus that provides.
The technical solution of the utility model is achieved in that
A kind of eccentric shaft slot boring aperture apparatus is provided, it is characterized in that: a sleeve block is arranged, be equipped with one on the sleeve block and be placed in the excentric sleeve in the two through hole on the sleeve block, a ccontaining rotation processing axle in the described excentric sleeve, rotation processing axle front end is provided with cutter and uses as the slot boring hole; The affixed drive of excentric sleeve one end, drive drive excentric sleeve serves as that axle rotates with the axle center of through hole; Excentric sleeve is positioned at the position part between the sleeve block two through hole, has first rolling bearing, snap ring, spring, second rolling bearing of being arranged on the excentric sleeve to connect in regular turn; After the tensioned, first rolling bearing and second rolling bearing are close to the upright piece inboard of sleeve block, give horizontal location with excentric sleeve, and the clearance control when drive is rotated is in machining accuracy.
Aforesaid eccentric shaft slot boring aperture apparatus is characterized in that: described excentric sleeve is positioned at the position part between the sleeve block two through hole, is provided with the excentric sleeve elastic positioning device.Its effect is about to excentric sleeve and gives horizontal location as hereinbefore, and the clearance control when drive is rotated is in machining accuracy
When the utility model used, excentric sleeve was that axle rotates with the two through hole, and rotation processing axle carries out the operation of slot boring hole, because the radius of turn that rotation processing axle is fixed a cutting tool is less, the aperture in slot boring hole is limited, behind the employing excentric sleeve, strengthen the radius in cutter slot boring hole, and improved machining accuracy.
The utility model is simple in structure, and dexterous being suitable for improved the precision in catapult shell slot boring hole, for the production automation of catapult shell provides a kind of practical equipment.
