Abstract
The utility model discloses a round part clamp for a numerical control lathe. The round part clamp for the numerical control lathe comprises a chuck, a connecting seat, a connecting and limiting stud and a braking stud pin. A chuck locating hole is formed in the axial direction of the connecting seat, the locating hole is a through hole, the rear portion of the chuck is inserted into the chuck locating hole of the connecting seat and is locked through the braking stud pin, a clamping jaw used for clamping a round part is arranged on the head of the chuck, and internal threads in threaded connection with the connecting and limiting stud are arranged on the rear part of the chuck. When the round part clamp for the numerical control lathe is used, the connecting seat is directly connected with the numerical control lathe, the chuck is connected with a hydraulic pull rod of the numerical control lathe through the connecting and limiting stud, the automatic clamping process of the part is achieved, machining errors caused by mounting errors of the clamp and jumping of a main shaft of the lathe can be eliminated to the maximum extent, machining precision is high, clamping repeatability is good, and form and position error changes between parts are small.
Description
Technical field
The utility model relates to the round part clamp that a kind of numerically controlled lathe is used.
Background technology
Bearing ring part mill is processed as under the prerequisite that reaches maximal efficiency and higher surface quality, and mill allowance reduces year by year.Part Vehicle Processing morpheme error and surface quality have been proposed to requirements at the higher level.
At present, bearing ring part Vehicle Processing lathe mainly contains two kinds: a kind of is old-fashioned instrument lathe, and parts fixation repeatable accuracy is better, but Artificial Control dimensional accuracy, processing dimension scattered error is larger, and operation is long, labour intensity is large; One is numerically controlled lathe, adopts scroll chuck to carry out clamped one time one-shot forming Vehicle Processing, and dimensional accuracy is high, operation is single, can people's multi-machine operation, but is subject to chuck precision impact, and between part, morpheme error change is larger.
Utility model content
The purpose of this utility model is to provide the round part clamp that numerically controlled lathe that a kind of machining accuracy is high is used, for mill processing provides more excellent blank part.
The technical scheme that realizes the utility model object is: the round part clamp that a kind of numerically controlled lathe is used, comprises chuck, Connection Block, the spacing double-screw bolt of connection and braking stud pin; Described Connection Block be axially arranged with chuck locating hole; Described locating hole is through hole; Insert in the locating hole of Connection Block at the rear portion of described chuck, and by the locking of braking stud pin; The head of described chuck is provided with the jaw for clamping round part, and the rear portion of chuck is provided with and the internal thread that is connected spacing double-screw bolt and is threaded.
The inwall at the front end inlet place of the locating hole of described Connection Block is taper seat, and the neck of the jaw of chuck is the conical surface coordinating with it.
Described Connection Block rear portion is provided with and axially vertical locking hole; Described locking hole is through hole, and is provided with internal thread; Described braking stud pin is threaded with the locking hole of Connection Block; The outer wall at the rear portion of described chuck is provided with locking slot, and the width of locking slot is suitable with the diameter of braking stud pin.
Adopt technique scheme, the utlity model has following beneficial effect: (1) the utility model in use Connection Block is connected with the direct of numerically controlled lathe, chuck is connected with numerically controlled lathe hydraulic pressure draw-bar by connecting spacing double-screw bolt, realize the Automatic-clamping process of part, can eliminate to greatest extent the mismachining tolerance causing due to fixture alignment error and pulsation of machine tool main shaft, machining accuracy is high, and clamping repeatability is good, and between part, morpheme error change is little.
(2) the utility model makes the meeting dress precision of part reduced by the impact of main axis jerking, therefore can further improve part circularities.
