Abstract

The utility model relates to a multifunctional combined clamp which belongs to the utility model of the cutter collet on the lathe. The structure of the utility model is that a principal shaft is provided with an angle changing body, a circumrotation body and a group of collects, and the circumrotation body which is changed into the cutter is positioned and locked through the positioning device and the locking device. The utility model can be installed in tailstock of lathe, and provided with different cutters to accomplish the working procedures of the drilling, the broaching, the reaming, the tapping, etc. According to the requirements. The utility model is suitable for various types of lathe. The auxiliary time of the cutter changing can be saved, the effective availability of the lathe can be increased, the production efficiency can be raised and the labor intensity of the worker is reduced by the using of the utility model.

Description

Multi-functional built-up jig

Multi-functional built-up jig described in the utility model belongs to the improvement invention to universal cutter chuck on the tail stock, is a kind of multi-functional built-up jig of fast changeable cutter.

At present in machining is produced, all kinds lathe is finished by the knife rest that is contained on the tail stock operations such as boring that workpiece carried out, reaming, fraising, tapping.And at every turn can only a kind of cutter of clamping, then process for the workpiece of working procedures, exist whenever machine a procedure after, must change the processing work that cutter just can be finished next process, so exist to change that cutter is frequent, waste man-hour, operation inconvenience, use problems such as trouble.Therefore the multi-functional built-up jig of studying a kind of novel fast changeable cutter is very necessary.

In view of above-mentioned existing in prior technology problem task of the present utility model be design a kind of applicable to hole on the various model lathes, the novel clamp of work such as reaming, fraising, rose silk.This multi-functional built-up jig can be finished a processing job such as boring, reaming, fraising, tapping, drill centers according to three kinds of different cutters of a clamping of processing request of workpiece.No matter single-piece production or produce in batches and all can accomplish a required clamping of three kinds of cutters has reduced the non-cutting time of changing chuck and cutter, has increased the effective rate of utilization of lathe, thereby has improved productivity ratio, alleviated working strength of workers.Therefore the utility model is a kind of practical Multifunction built-up jig that is suitable for.

The utility model is a kind of multi-functional built-up jig, it is characterized in that being fixed with on main shaft the angle body, and rotary body is connected with the angle body by bearing.At the taper shank that is fixed with on the rotary body more than three or three, the center line of the center line of taper shank and main shaft coincides when Working position.The positioner of angle body of the present utility model and rotary body is made up of place kick, spring, housing screw, and the locking of back, location is finished by eccentric shaft, set lever.On each taper shank of the present utility model chuck is housed all, and on each chuck different cutters is housed all.

Multi-functional built-up jig described in the utility model belongs to the fix a cutting tool improvement invention of chuck of lathe.And be loaded on the tailstock of lathe, three different cutters can be installed as required, and then finish processing work such as boring, reaming, fraising, tapping, drill centers.The utility model is simple in structure, easy to manufacture and will pass by can only adorn on chuck the old technology of a cutter, changes into the employing modular fixture, and the new process of three cutters can be housed.The utility model is applicable to the lathe of various models, can finish kinds of processes such as boring, reaming, fraising, rose silk, drill centers, brill stepped hole on same workpiece.Because but each clamping three is different cutters, thus saved in single-piece or in producing in batches the replacing cutter non-cutting time, increased lathe effective rate of utilization, improved production efficiency, alleviated working strength of workers.So application of the present utility model will produce positive effect, for the processing of engine lathe has increased a kind of novel clamping cutter arrangement.

Accompanying drawing of the present utility model is multi-functional built-up jig structural representation.Among the figure: 1 main shaft, 2 angle bodies, 3 housing screws, 4 place kick, 5 springs, 6 rotary bodies, 7 taper shanks, 8 end caps, 9 nuts, 10 bearings, 11 chucks, 12 eccentric shafts, 13 set levers

Specific embodiment of the utility model as shown in drawings, its structure is to install an angle body [2] on the main shaft of Morse's taper [1] having.Rotary body [6] is contained in above the angle body [2], and can rotate around it by the effect of bearing [10].On rotary body [6], be fixed with three taper shanks [7], chuck [11] all is housed on each taper shank [7].Different cutters is housed to finish the needs of different processing technologys, as boring, reaming, fraising etc. respectively on three chucks [11].Bearing [10] fixedly be to finish by nut [9].And adopt end cap [8] that bearing [10] is encapsulated in the dead eye in case dust and other impurities falls into.When utilizing the utility model work, at first main shaft [1] is inserted in the tailstock of lathe, be seated by its Morse's taper.Rotate rotary body [6] then, making needs the cutter of work to put in place, and when the dead in line of tool axis and the main shaft [1] of processing, it is interior and locate that then place kick [4] is pushed locating slot by spring [5].The tight power size of giving of spring [5] is to be determined by the position of housing screw [3] screw-in.Set lever [13] is moved with hand in location back, presses eccentric shaft [12] and rotary body [6] is fastened on the angle body [2], at this moment just can realize the work of processing normally.Needs according to processing repeat above-mentioned action, just can realize changing different cutters, finish required processing technology requirement.

Claims

1 one kinds of multi-functional built-up jigs, it is characterized in that on main shaft [1], being fixed with angle body [2], rotary body [6] is connected with angle body [2] by bearing [10], on rotary body [6], be fixed with the taper shank [7] more than three or three, when Working position, the center line of the center line of taper shank [7] and main shaft [1] coincides.

2 multi-functional built-up jigs according to claim 1, the positioner that it is characterized in that angle body [2] and rotary body [6] is made up of place kick [4], spring [5] housing screw [3], and the locking of back, location is finished by eccentric shaft [12], set lever [13].

3 multi-functional built-up jigs according to claim 1 is characterized in that on each taper shank [7] chuck being housed all, and on each chuck different cutters are housed all.
