Description

Deep hole precision machining equipment Technical Field The utility model relates to the technical field of deep hole machining, in particular to deep hole precision machining equipment. Background In the machining, the deep hole machining is a machining process of holes with the hole depth and the aperture ratio not smaller than 5, and is suitable for machining of precision parts. Because the drill bit is longer in deep hole processing, the drill bit is easy to shake in the high-speed rotation and feeding process, so that the size deviation exists in the bore diameter of the drilled hole, the drill bit is seriously and even broken, and the processing quality is influenced. Disclosure of Invention The utility model aims to overcome the existing defects, and provides deep hole precision machining equipment which can effectively reduce the shaking of a drill bit in the machining process, improve the drilling precision and the machining quality, prolong the service life of the drill bit and effectively solve the problems in the background technology. In order to achieve the purpose, the deep hole precision machining equipment comprises a motor and a drill bit, wherein the drill bit is arranged at the output end of the motor, the motor is fixed on a fixing plate, at least one group of locating rib groups are arranged on the outer side face of the drill bit, locating ribs in the locating rib groups are uniformly distributed around the central axis of the drill bit, locating sleeves are arranged on the outer side face of the locating rib groups, grooves matched with the locating ribs are formed in the inner side face of the locating sleeves, an outer sleeve is arranged on the outer side face of the locating sleeves, a bearing is arranged between the locating sleeves and the outer sleeve, a support is arranged at the lower end of the outer sleeve, and is fixed on a supporting plate through bolts and integrally connected with the fixing plate. As a preferable technical scheme of the utility model, the supporting plate is provided with two rows of mounting holes, and the mounting holes correspond to the positions of the bolt holes on the support. As a preferable technical scheme of the utility model, the lower end of the fixed plate is provided with a sliding frame capable of horizontally moving. As a preferred embodiment of the present utility model, the fixing plate is connected to the carriage by a bolt. As a preferable technical scheme of the utility model, the lower end of the sliding frame is slidably connected in the sliding seat, the sliding seat is fixed on the upper surface of the mounting plate, one side of the sliding frame is connected with the telescopic end of the hydraulic telescopic rod, the fixed end of the hydraulic telescopic rod is fixed on the vertical plate, and the vertical plate is fixed on the upper surface of the mounting plate. Compared with the prior art, the deep hole precision machining equipment has the beneficial effects that the positioning ribs are uniformly distributed on the drill bit, the positioning sleeve is in close plug-in fit with the positioning ribs through the grooves in the positioning sleeve, the positioning sleeve is in rotary connection with the outer sleeve through the bearing, and the outer sleeve is fixed on the supporting plate, so that the drill bit can drive the positioning sleeve to rotate together in the rotary process, and the outer sleeve is motionless, so that radial runout in the rotary process of the drill bit is limited through the positioning sleeve, the shaking of the drill bit is effectively reduced, the position of the positioning sleeve can be adjusted according to the length of the drill bit, or the number of the positioning sleeves is increased, the drill bit is effectively limited, and the drilling precision is ensured.
