Abstract
The invention relates to a spring jacket and the use thereof, in particular to a spring jacket used in a numerically controlled lathe and a hand lathe and the use of the spring jacket, and belongs to the field of machining manufacture. The outline of the spring jacket takes the shape of a straight cylinder, so as to be clamped with a workpiece, and be used for clamping a rod part. Due to the elasticity of spring steel, the radial force of a chuck plate claw or an expansion chuck exerts on the spring jacket to ensure the clamping of the spring jacket, when the chuck plate claw or the expansion chuck is released, the spring jacket and the workpiece can be mounted in or taken out together. When the spring jacket is used for clamping a workpiece of which the rod part is thinner and the head is large in diameter, the machining precision can be guaranteed, and the cost is reduced. A normal chuck plate claw (hard claw) only can clamp workpieces of diameters larger than 10 mm, and workpieces of diameters smaller than 10 mm can be turned and processed due to the adoption of the spring jacket while the machining precision is guaranteed, so as to avoid replacement with a tailor-made chuck jaw.
Description
Technical field
The present invention relates to a kind of spring chuck and uses thereof, relate to a kind of numerically controlled lathe and palm lathe concretely with spring chuck and uses thereof, it belongs to field of machining and machinebuilding technology.
Background technology
At present; Being applied to often has a kind of workpiece in the centre numerically controlled lathe processing work, tiny and the big and flat common employing of head diameter of bar portion is one section of lathe chuck pawl turning, just can not use when so just making the general workpiece of chuck jaws reface; Need change the normal chuck jaws of a cover in addition; Thereby increased expense, perhaps because diameter is too small, normal chuck jaws (hard pawl) can only the clamping diameter greater than the workpiece of 10mm; And diameter just can't be processed less than the workpiece of 10mm in clamping, needs to change special chuck jaw (as using soft pawl etc.); Instrument lathe and hand are pulled lathe and are mostly adopted collet to clamp fast, are applicable to the processing of finding in enormous quantities, can't clamping and head dimensions is processed the workpiece of the little blank of bar portion again greater than bar portion size.
Summary of the invention
In view of the defective that prior art exists, the objective of the invention is to provide a kind of and remain elasticity after utilizing spring steel heat treatment, can lock novel spring chuck of the mechanism design that resiles again after unclamping and uses thereof after the clamping.
For realizing above-mentioned purpose; The technical solution that the present invention adopted: a kind of spring chuck; It adopts the helical spring steel is chuck, and chuck inside is provided with through hole, and said chuck is provided with 8 the narrow grooves parallel with center line; Said narrow groove lays respectively on 8 bisectors of chuck, and wherein 4 narrow groove left ends that are positioned at 4 bisectors of anchor clamps open to apart from right-hand member 2 ~ 5cm place; All the other 4 narrow groove right-hand members open to apart from left end 2 ~ 5cm place.
Said narrow groove bosom equates with the distance of chuck end.
Said spring chuck is applied to the lathe in machining workpiece; Workpiece to be processed places chuck inner through through hole, and the workpiece to be processed end places the chuck outside, and lathe chuck clamps chuck; Chuck is through the clamping workpiece to be processed of narrow groove, and lathe tool is processed workpiece to be processed.
Said spring chuck is applied to palm lathe processing work; Workpiece to be processed places chuck inner through through hole, and the workpiece to be processed end places the chuck outside, and collet clamps chuck; Chuck is through the clamping workpiece to be processed of narrow groove, and lathe tool is processed workpiece to be processed.
Project organization of the present invention is simple; Using its profile is that right circular cylinder is convenient to chuck and is clamped with workpiece; So can be used for clamping bar portion, the present invention utilizes the elasticity of spring steel, and the radial load of chuck jaws or collet is done and is used for the spring chuck and makes its clamping work; Chuck jaws or collet are lax, the taking-up of can packing into together of spring chuck and workpiece.The workpiece that head diameter is big and flat for bar portion is tiny uses this spring chuck, can guarantee machining accuracy on the one hand; Reduced expense on the other hand; And for because diameter is too small, normal chuck jaws (hard pawl) can only the clamping diameter greater than the workpiece of 10mm, and diameter is less than the workpiece of 10mm; Use the present invention can make workpiece can reach the purpose of turning processing, and guarantee machining accuracy.Need not change special chuck jaw like this.
