Abstract
A tape sleeve expander fixture of a numerical-control lathe is provided with a fixed seat, a connecting rod is mounted in a fixed seat inner hole, a disc-shaped spring is sleeved on the tail portion of the connecting rod, the disc-shaped spring supports between a baffle ring at the tail end of the connecting rod and an end face of a fixed seat expanding hole, a movable pushing sleeve is sleeved on the periphery of the front portion of the fixed seat, a connecting pin is fixed at the front end of the connecting rod, the connecting pin penetrates through a slide hole on the fixed seat to be connected with the movable pushing sleeve, an expander is sleeved on the outer periphery of the movable pushing sleeve, contact surfaces between the movable pushing sleeve and the expander are conical surfaces corresponding to each other, an end face of the inner side of the expander is butted onto a projection of the fixed seat, a lock nut is arranged at the end of the fixed seat, and the lock nut is abutted onto an end face of the outer side of the expander. Processing of spigots, end faces and chamfers at two ends of a motor shell is completed via clamping of the taper sleeve expander fixture in one step, runout of an inner cavity of the motor shell on axes of the spigots at two ends is effectively controlled, and production efficiency is greatly improved while processing cost is reduced.
Description
Technical field:
The utility model relates to a kind of anchor clamps, and especially a kind of numerically controlled lathe tapered sleeve expander anchor clamps clamp it when being used to process motor casing both ends of the surface and seam.
Background technology:
The conventional machining process of motor casing both ends of the surface and seam is with end seam location, processing other end seam; Perhaps with the inner chamber location, motor casing two ends seam is processed in tune at twice.Not only working (machining) efficiency is low, and labor strength is big, the processing cost height, and, cause defectives such as motor noise is big, heating because the error that processing mode is improper and resetting causes makes the motor casing inner chamber very poor to beating of two ends seam axis.
Summary of the invention:
The purpose of this utility model provides a kind of numerically controlled lathe tapered sleeve expander anchor clamps, solves to reverse end for end to process the defective of bringing that working (machining) efficiency is low, labor strength is big, processing cost is high, error is big in original motor casing both ends of the surface and the seam processing technology at twice.
The purpose of this utility model realizes as follows: a holder is arranged, the holder endoporus is equipped with extension bar, the extension bar rear portion is with disk spring, disk spring supports between the end face of the baffle ring of extension bar rear end and holder reaming, be with mobile pushing sleeve on the anterior cylindrical of holder, the fixedly connected pin of extension bar front end, the slide opening that connecting pin passes on the holder is connected with mobile pushing sleeve, mobile pushing sleeve periphery is with expander, the contact-making surface of mobile pushing sleeve and expander is the corresponding conical surface, the expander inner side end leans against on the boss of holder, and the holder end is provided with locking nut, and locking nut leans on the end face of the expander outside.In released or when compression when disk spring, extension bar drives mobile pushing sleeve and moves, and makes expander harmomegathus, and motor casing is enclosed within on the expander clamped or unclamp.When expander anchor clamps tensioner motor casing inner chamber, can process motor casing two ends seam, end face and chamfering simultaneously.
Clamping of the utility model finishes the processing of motor casing two ends seam, end face, chamfering, effectively controlled the motor casing inner chamber to the beating of two ends seam axis, and significantly improved production efficiency, reduced processing cost.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
With reference to accompanying drawing, a holder 1 is arranged, holder 1 endoporus is equipped with extension bar 4, extension bar 4 rear portions are with disk spring 7, disk spring 7 is supported between the end face of reaming of the baffle ring of extension bar 4 rear ends and holder 1, be with mobile pushing sleeve 3 on the holder 1 anterior cylindrical, the fixedly connected pin 5 of extension bar 4 front ends, the slide opening that connecting pin 5 passes on the holder 1 is connected with mobile pushing sleeve 3, mobile pushing sleeve 3 peripheries are with expander 2, mobile pushing sleeve 3 is the corresponding conical surface with the contact-making surface of expander 2, expander 2 inner side ends lean against on the boss of holder 1, holder 1 end is provided with locking nut 6, and locking nut 6 leans on expander 2 outside end faces, and holder 1 end is provided with back tightening nut and leans locking nut 6 and prevent to become flexible.To the clamping of workpiece with unclamp, be to realize by disk spring 7 as main clamping force.When promoting extension bar 4 and compressing disk spring 7, extension bar 4 moves in holder 1, releases mobile pushing sleeve 3 by connecting pin 5, and expander 2 shrinks, and expander 2 external diameters diminish, and workpiece is released; After the external force that promotes extension bar 4 was removed, disk spring 7 promoted extension bar 4, and extension bar 4 retracts mobile pushing sleeve 3 by connecting pin 5, and expander 2 expands, and expander 2 external diameters increase, and workpiece is clamped.
