Abstract

The utility model relates to a fixing hoop type lathe main shaft centre, which comprises a centre, wherein the forepart of the centre is a cylinder and is provided with a hoop positioning device. The main shaft centre has the advantages that the main shaft centre solves the problem of fixing a hoop with a three-jaw chuck, effectively guarantees the stability of workpieces in a cutting process, has good self-locking performance and high positioning precision, can bear the semi-finish machining and finish machining of solid-axle workpieces, which are heavy, are provided with centre bores at two ends and have the diameter of inner bores not more than phi 40 millimeters, ensures part machining precision and product quality, can be directly arranged on a lathe main shaft, omits the workload of detaching the three-jaw chuck and installing a driver plate, reduces labor intensity, improves production efficiency, is simple in structure, convenient to load/unload, convenient for the semi-finish machining and finish machining of the workpieces supported by a front centre and a back centre, such as shaft sleeves which are positioned on small-taper cylindrical core shafts or spline core shafts, gears, worm gears, worms, screw rods, slender shafts and rod workpieces, is safe and reliable in use, good in effect and widely applicable to common lathes of various models such as C620, C620-1, CA6140, CA6150 and the like, and is easy to popularize and apply.

Description

Fixedly the clipping type lathe spindle is top
Technical field
The utility model belongs to engine lathe frock jig field, and it is top to relate to a kind of fixedly clipping type lathe spindle.
Background technology
The processing workpiece of the top support in front and back on engine lathe, generally adopt at present the processing method of clamping soft centre, be horizontal group of rod of existing clamp to be dialled on a pawl of scroll chuck, drive the workpiece rotation when being installed, because clamp is unfixing, obvious floating putting is under the effect of cutting the power of disappearing, clamp is trembled on scroll chuck, make surface of the work produce vibrations, the especially cutting of workpiece of installing on thin mandrel and thin axle, stock class workpiece all can not guarantee the stability of machining.
When finish turning leading screw, worm screw class workpiece, need positive revesal, when the main shaft rotating, horizontal group of rod of clamp can clash on the claw of scroll chuck back and forth, cause the soft centre change, whenever walking one stroke when just changeing cutting all will dial clamp in position again, owing to produce vibrations during cutting, workpiece surface roughness can not get ensureing, thereby influences crudy.
When processing heavier workpiece, soft centre can not load-bearing, the claw of scroll chuck uses through long-time, front end generally weares and teares into broadening formation, the weight of workpiece itself and under the effect of cutting force and the vibrations that produce all may make the soft centre of institute's clamping change to any direction, even small change, also can cause the circle of workpiece to beat, specification requirement such as circular shaft degree, end face squareness, the depth of parallelism overproof, can not guarantee the crudy of workpiece.
Generally need two people to install when the scroll chuck of removing stage makeup and costume, when changing dial, labour intensity is big, and production efficiency is low.
Summary of the invention
The purpose of this utility model is to provide a kind of fixedly clipping type lathe spindle top, solved the fixing problem of clamp and scroll chuck, guarantee the stability of workpiece machining, reliably guarantee the machining accuracy and the quality of workpiece, reduce labour intensity and enhance productivity.
The technical solution adopted in the utility model: a kind of fixedly clipping type lathe spindle is top, comprises toply, and described top front portion is a cylinder, and the clamp positioner is installed.
The positioning sleeve of described clamp positioner is slidingly installed on top anterior external diameter, is fixedly connected with shifting block on the positioning sleeve, on the inclined plane of shifting block jackscrew is installed, and lock-screw is installed on the positioning sleeve.
Described top rear portion is a Mohs 5#6# cone.
The positive beneficial effect that the utility model had:
1. solve the fixing problem of clamp and scroll chuck, effectively guaranteed the stability of workpiece when machining;
2. self-locking property is good, and the positioning accuracy height can carry heavier two ends and have semifinishing, the fine finishining that centre bore and diameter of bore are no more than the solid axle class workpiece of Φ 40mm scope, reliably guarantees part processing precision and product quality;
3. directly be contained on the machine tool chief axis and get final product, substituted the processing tool jig of existing soft centre, omitted the scroll chuck of removing stage makeup and costume, the workload of dial is installed, reduce labour intensity, enhance productivity;
4. simple in structure, easy to loading and unloading, the workpiece of top support before and after being convenient to, as: axle sleeve class, gear, the worm gear of on conelet degree cylindrical mandrel, spline mandrel, locating, the semifinishing of worm screw, leading screw, slender axles, rod workpieces, fine finishining;
5. safe and reliable, effective, be widely used in the engine lathe of multiple models such as C620, C620-1, CA6140, CA6150, be easy to apply.
Description of drawings
Fig. 1 is the front view of the utility model structural representation;
Fig. 2 is the right view of the utility model structural representation;
Fig. 3 is the utility model scheme of installation.
The specific embodiment
Consult Fig. 1, shown in Figure 2, a kind of fixedly clipping type lathe spindle is top, mainly comprises top 1, clamp positioner 2 etc.; Its top 1 material is 9CrSi, and rear portion 101 is a cone, and Mohs 5#6# is top identical with existing lathe spindle, and anterior 102 is cylinder, and clamp positioner 2 is installed.
Described clamp positioner 2 comprises shifting block 201, jackscrew 202, positioning sleeve 203, lock-screw 204 etc.; Its positioning sleeve 203 is slidingly installed on top 1 front portion 102 external diameters, be welded with shifting block 201 on the positioning sleeve 203, on 60 ° of inclined planes of shifting block 201, jackscrew 202 is installed, lock-screw 204 is installed on the positioning sleeve 203, be used for locking with top 1 front portion 102.
Consult shown in Figure 3, during installation, rear portion 101 with top 1 is installed in lathe spindle 3 taper holes and locatees, anterior 102 stretch out from scroll chuck 4 claws, and the clamp positioner 2 that is slidingly installed, by the jackscrew 202 fixing group rod formula workpiece clamps of dialling on scroll chuck 4 claws 5, lock gently with lock-screw 204, workpiece 6 is supported by lathe spindle top 1 and tailstock centre 7 front and back, make spindle top 1, workpiece 6, clamp 5, scroll chuck 4 be one, improved the stability of rigidity and machining.
