Abstract
The utility model discloses a main shaft component of a digital controlled lathe, and belongs to the machinery field. The main shaft component of the digital controlled lathe comprises a cutter handle, a pop-rivet, a main shaft, a pull rod, a belleville spring, steel balls, an end-front key and a taper hole, wherein the taper hole being 7:24 is formed in the front end of the main shaft, the cutter handle is clamped in the taper hole and is located through the end-front key, the four steel balls are arranged in a radial hole in the front end of the pull rod and clamped in an annular groove of the pop-rivet, an upper cavity of a hydraulic cylinder is connected with return oil, a spring pushes a piston to move upwards, the pull rod moves upwards under the effect of the belleville spring, and the piston, the hydraulic cylinder, a travel switch, a compressed air pipe connector, a travel switch and the spring are arranged at the tail portion of the main shaft component. The main shaft component of the digital controlled lathe has the advantages that using is convenient, working efficiency is improved, an automatic cutter clamping device is arranged in the main shaft so that automatic assembling and disassembling of a cutter can be achieved, cuttings or dirt can be removed through the compressed air pipe connector, and accuracy of clamping the cutter is ensured.
Description
Technical field
The utility model belongs to mechanical field, relates in particular to a kind of spindle of numerical control lathe parts.
Background technology
Machine tool chief axis refers to the axle that drives workpiece or cutter rotation on the lathe.Usually form spindle unit by main shaft, bearing and driving member (gear or belt wheel) etc.In machine, be mainly used to support driving parts such as gear, belt wheel, transmit motion and moment of torsion, as machine tool chief axis; What have is used for clamping workpiece, as axle.Except main motions such as planer, broaching machine were straight-line lathe, most of lathes had spindle unit.The kinematic accuracy of spindle unit and the rigidity of structure are the key factors that determines crudy and stock-removing efficiency.The index of weighing the spindle unit performance mainly is running accuracy, rigidity and velocity adaptive.A lot of machine tool chief axis all can not be realized the automatic loading and unloading of cutter on the present market, use inconvenience.
The utility model content
The purpose of this utility model is to provide a kind of spindle of numerical control lathe parts, can effectively address the above problem.
The utility model is realized by following scheme:
The utility model comprises handle of a knife, blind rivet, main shaft, pull bar, spring b, steel ball, the preceding key of end, taper hole, front-end of spindle has the taper hole of 7:24, the handle of a knife clamping is in taper hole, by key location before the end, 4 steel balls are arranged in the pull bar front end radial hole, be stuck in the annular groove of blind rivet, the hydraulic cylinder epicoele is connected oil return, move on the spring a push piston, pull bar moves up under the effect of spring b, at the afterbody of spindle unit, design has piston, hydraulic cylinder, travel switch, compressed air pipe joint, travel switch, spring a.
Described spindle unit is to realize the location of cutter holder and clamping by the axle journal of tensioning mechanism tension taper shank cutter holder tail end.
Described knife bar pull bar relies on frictional force to be fastened on the main shaft.
Described compressed air is blown in the taper hole by the central through hole of pipe joint through piston and pull bar.
Described two travel switches are responsible for sending signal.
The beneficial effects of the utility model are: easy to use, increase work efficiency, and be provided with the cutter automatic clamping device in the main shaft, can realize the automatic loading and unloading of cutter, the compressed air pipe joint can be removed smear metal or foul totally, to guarantee the clamping precision of cutter.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Among the figure: the 1-handle of a knife; The 2-blind rivet; The 3-main shaft; The 4-pull bar; 5-spring b; The 6-piston; The 7-hydraulic cylinder; The 8-travel switch; 9-compressed air pipe joint; The 10-travel switch; 11-spring a; The 12-steel ball; Key before the 13-end; The 14-taper hole.
The specific embodiment
Further specify the utility model below in conjunction with Figure of description.
As shown in the figure, front-end of spindle has the taper hole 14 of 7:24, is used for clamping handle of a knife 1.Key 13 had both been made cutter positioning usefulness before the end, can pass through its transmitting torque again.This lathe is to realize the location of cutter holder and clamping by the axle journal of tensioning mechanism tension taper shank cutter holder tail end.When clamping cutter holder, hydraulic cylinder 7 epicoeles are connected oil return, move on the spring a11 push piston 6, are in shown position, and pull bar 4 moves up under the effect of spring b5.Be contained in 4 steel balls 12 in the pull bar 4 front end radial holes and enter in people's main shaft 3 holes less taper hole 14 places of diameter and be forced to radially draw in and stick in the annular groove of blind rivet 2, thereby 4 tensions of knife bar pull bar, rely on frictional force to be fastened on the main shaft 3.In the time of cutter holder need being unclamped before the tool changing, pressure oil enters hydraulic cylinder 7 epicoeles, and piston 6 pushing drawing rods 4 move down, and spring b5 is compressed.When steel ball 12 is displaced downwardly to pull bar 4 when entering taper hole 14 places that diameter is bigger in main shaft 3 holes, it just no longer can retrain the head of blind rivet 2, and then the shoulder end face of pull bar 4 front end endoporus is run into blind rivet 2, cutter holder top pine, this moment, travel switch 10 sent signal, and tool-changing mechanical arm takes off with being about to cutter holder.Compressed air is blown in the main shaft 3 dress tool bores by the central through hole of pipe joint 9 through piston 6 and pull bar 4, smear metal or foul is removed totally, to guarantee the clamping precision of cutter.After manipulator was loaded onto main shaft 3 to new cutter, hydraulic cylinder 7 was connected oil return, and spring b5 strains cutter holder again.After the cutter holder tension, travel switch 8 sends signal.
