The utility model relates to a fixture for machining an inner hole of an oil shaft sleeve, which comprises a sleeve cavity arranged in a sleeve fixture and an end cover sleeve fixture. The sleeve cavity is a cylindrical cavity, and a sleeve through hole coaxial with the sleeve cavity is arranged at the left end of the sleeve cavity. The cross-section diameter of the through hole of the sleeve is smaller than the diameter of the sleeve cavity, and the sleeve fixture is provided with a sleeve through hole. The outer right edge of the clamp is provided with external threads; the right end of the end cover is provided with a circular cavity coaxial with the central hole; the inner wall of the circular cavity is provided with internal threads matching the external threads of the clamp sleeve; and the left end of the sleeve clamp is clamped with a three-jaw chuck. The utility model has the advantages of simple structure, safety and reliability, and greatly improves the production efficiency after use.

一种石油轴套加工内孔夹具
本技术涉及石油轴套内孔磨削产品加工的夹具,具体涉及一种石油轴套加工内孔夹具。
技术介绍
现有的异型产品尤其对于大批量的石油轴套产品,在深加工磨削内孔过程中,大多数采用卡盘装夹的方式单件加工磨削内孔,这样加工的优点是精度能够保证,但是缺点是效率低,适合加工小批量产品,对于大批量产品而言,生产加工效率低,不能够满足生产需要,同时卡盘装夹打表找正对于操作工有较高的技术水平要求。
技术实现思路
针对上述问题,本技术提供了既可以保证产品加工精度,又能够提高加工效率的轴套加工内孔夹具,本技术的技术方案是:一种石油轴套加工内孔夹具,包括套筒夹具和端盖,套筒夹具内设有套筒型腔,套筒型腔为圆柱形型腔,在套筒型腔的左端还设有与套筒型腔同轴的套筒通孔,该套筒通孔的截面直径小于套筒型腔,套筒夹具的右部外缘设有外螺纹;端盖右端设有供内圆磨头通过中心孔,左端设有与中心孔同轴的圆形腔,圆形腔的内壁上设有与夹具套筒的外螺纹相匹配的内螺纹,套筒套筒夹具的左端部采用三爪卡盘装夹。所述的中心孔小于套筒通孔的圆截面直径。套筒型腔的直径小于端盖圆形腔的直径。对于操作工的水平要求不高, ...
