Abstract

The utility model discloses a lathe clamp for machining a gear. The lathe clamp for machining the gear comprises a connection flange plate. A through hole is formed in the center of the connection flange plate. An elastic clamping sleeve is connected to the front end face of a transition flange plate. The center of the front end face of the elastic clamping sleeve extends outwards and is provided with a positioning boss. The outer edge of the elastic clamping sleeve extends outwards in the axial direction and is provided with a plurality of clamping claws. The clamping claws are evenly distributed around the central axis of the elastic clamping sleeve. A plurality of sets of pin rollers are distributed on the inner circumferences of the clamping claws which are evenly distributed. The pin rollers are fixed through a retainer. An inner circle arc formed by the clamping claws is matched with an outer circular arc formed by the pin rollers. The clamp is designed to be a pitch circle clamp capable of being applied on a lathe, the sets of elastic pin rollers in the retainer are used for clamping a pitch circle of the gear, the clamping force can be evenly adjusted along with tooth forms of the gear, return error does not exist, the clamp is of a micro-motion clamping return high-precision clamp, a positioning standard of a gear end face is good, clamping is convenient during a machining process, a machined tooth-formed surface is not damaged, and meanwhile the requirement for perpendicularity of an inner hole of the gear and the end face of the gear is met.

Description

A kind ofly add the turning attachment that work gear is used

Technical field

The utility model relates to a kind of anchor clamps that work gear is used that add, and especially a kind ofly adds the turning attachment that work gear is used.

Background technology

In the process of processing automobile engine gear and idle gear component, traditional method is at grinding machine spring chuck clamping work pieces, can only finish the processing of grinding out, its end face and other operation need to process at lathe, repeatedly the location has caused the position degree in end face and hole overproof, its clamping is the size instability after trouble, inefficiency, the processing also, can not satisfy production in enormous quantities.

Summary of the invention

The utility model proposes a kind of turning attachment that work gear is used that adds, its purpose satisfies any gear and idle gear component product all can be processed at lathe, has also solved the problem that size after existing anchor clamps clamping trouble, inefficiency, the processing is unstable and can not satisfy production in enormous quantities.

In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: a kind ofly add the turning attachment that work gear is used, comprise mounting flange, it is characterized in that: the center of mounting flange is provided with through hole, be connected with elastic ferrule on the front end face of counter flange dish, the center of the front end face of elastic ferrule is outward extended with positioning boss, and the outer rim of elastic ferrule is outward extended with a plurality of claws vertically, and claw is around the central axis circumference uniform distribution of elastic ferrule; Be distributed with many group rollers at uniform claw inner periphery, roller is fixed by retainer, and the external arc that the interior circular arc that claw forms and roller form adapts.

Beneficial effect: the utility model becomes jig Design a kind of pitch-line chuck can be applied on the lathe, utilize the pitch circle of the elastic roller group clamping gear in the retainer, its clamping force can be regulated evenly with tooth-formation of gear, no return error, belong to fine motion and clamp the return high-accuracy clamp, the location benchmark of gear face is good, process is easy to setup, and do not hinder the toothed surfaces that processes, guarantee simultaneously the perpendicularity requirement of bore and end face again, improved benefit, reduced percent defective, simultaneously, tooth-formation of gear teeth directional and runout tolerance all are guaranteed, and are fit to produce in enormous quantities.

Fig. 2 is right view of the present utility model.

1 is the counter flange dish among the figure, the 2nd, and through hole, the 3rd, elastic ferrule, the 4th, positioning boss, the 5th, claw, the 6th, roller, the 7th, retainer, the 8th, gear.

The specific embodiment

As illustrated in fig. 1 and 2, a kind ofly add the turning attachment that work gear is used, comprise counter flange dish 1, the center of counter flange dish 1 is provided with through hole 2, be connected with elastic ferrule 3 on the front end face of counter flange dish 1, the center of elastic ferrule 3 front end faces is outward extended with positioning boss 4, and the outer rim of elastic ferrule 3 is outward extended with a plurality of claws 5 vertically, and claw 5 is around the central axis circumference uniform distribution of elastic ferrule 3; Be distributed with many group rollers at uniform claw 5 inner peripherys, every group of roller is made up of 2 ~ 4 rollers 6, and roller 6 is fixing by retainer 7, and the external arc that the interior circular arc that claw 5 forms and roller 6 form adapts.

Elastic ferrule described in the utility model refers to be subjected to behind the active force elastic deformation to take place, and can recover a kind of cutting ferrule of original state.

The utility model operation principle: with a kind of add turning attachment that work gear uses and machine tool chief axis be connected after, main shaft push rod on the lathe passes the through hole on the counter flange dish, to the elastic ferrule applied thrust, the thrust that the main shaft push rod acts on the elastic ferrule causes the elastic ferrule distortion, claw opens, the cogged retainer of the suit of packing into, push rod resets, the thrust that acts on this moment on the elastic ferrule disappears, the elasticity chuck is by elastic reset, claw restores to the original state, and retainer is clamped, thereby has clamped the gear on the retainer.

Claims

1. one kind adds the turning attachment that work gear is used, comprise mounting flange, it is characterized in that: the center of mounting flange is provided with through hole, be connected with elastic ferrule on the front end face of counter flange dish, the center of the front end face of elastic ferrule is outward extended with positioning boss, the outer rim of elastic ferrule is outward extended with a plurality of claws vertically, and claw is around the central axis circumference uniform distribution of elastic ferrule; Be distributed with many group rollers at uniform claw inner periphery, roller is fixed by retainer, and the external arc that the interior circular arc that claw forms and roller form adapts.
