Abstract
The utility model relates to an automatic broach-lifting device of a broaching machine. The structure of the automatic broach-lifting device of the broaching machine is that a push broach frame is fixed on a machine tool sliding plate, a push broach base is connected to the push broach frame, and a pull broach is in the push broach base. A bolt is located in a guide hole of the push broach frame and a guide hole of the push broach base, wherein the two guide holes are coaxial. A spring is located in a step hole of the push broach frame, wherein one end of the spring contacts the step hole bottom, and the other end of the spring contacts a step of the bolt. The moving distance of the bolt is from the outer end face of the push broach frame to an annular groove at the tail end of the pull broach, and an armature inside an electromagnet contacts one end of the bolt. According to the automatic broach-lifting device of the broaching machine, the existing shortcomings of the method of lifting a broach directly by a hand and manual operation of a broach-lifting mechanism can be overcome, automation of both the lifting of the broach and the placing of the broach is achieved, a button is clicked, and a processing cycle can be automatically finished under the control of a procedure. Working efficiency is improved, at the same time, labor intensity is greatly reduced, and moreover, the automatic broach-lifting device of the broaching machine is good in working conditions, easy to operate, safe and reliable.
Description
Technical field
The utility model relates to a kind of parts of plant equipment, is specifically related to a kind of automatic lifting knife system of broaching machine.
Background technology
When adopting the forming surface of broaching method processing parts closed inner chamber, workpiece can only take out from the broaching tool top, just can finish so broaching tool must break away from the push broach device.When again broaching, broaching tool must be reloaded in the push broach device, this process is called griffes.
Before the present utility model, the method for griffing is a kind of to be directly portable, and another kind is that the manual operation Griffe mechanism is finished.The little general employing in aperture the former, the employing latter that the aperture is large, this is because the weight of broaching tool own is larger, manually can't finish, and can only rely on manually operated Griffe mechanism and finish.Both operating efficiencies are all very low, and labour intensity is large, work under bad environment, and easily maloperation has larger potential safety hazard.
Summary of the invention
The purpose of the present utility model overcomes defects exactly, develops a kind of automatic lifting knife system of broaching machine.
The technical solution of the utility model is:
A kind of automatic lifting knife system of broaching machine, its technical characteristics is that the push broach frame is fixed on the lathe slide plate, the push broach seat is connected on the push broach frame, broaching tool is in the push broach seat, and latch is positioned at push broach frame, the coaxial pilot hole of push broach seat, and spring is positioned at the stepped hole of push broach frame, one end contacts with at the bottom of the hole, the other end contacts with the step of latch, and the displacement of latch is from the outer face of push broach frame to broaching tool afterbody cannelure, the armature of electromagnet inside and latch one end in contact.
The utility model has the advantage of that griffing, put cutter all realizes automation, inching button is finished a fabrication cycles automatically by programme-control.When increasing work efficiency, greatly reduce labour intensity, good operation conditions, simple to operate, safe and reliable.
Other concrete advantages of the present utility model and effect will go on to say below.
Description of drawings
Fig. 1---the utility model structural principle schematic diagram.
Wherein: at the bottom of push broach frame 1, push broach seat 2, broaching tool top 3, the cylindrical hole 4, pilot hole 5, stepped hole 6, spring 7, latch 8, armature 9, electromagnet 10, cannelure 11, broaching tool 12, lathe slide plate 13.
The specific embodiment
As shown in Figure 1:
Push broach frame 1 is installed on the lathe slide plate 13, is provided with the space in the middle of the push broach frame 1, and push broach seat 2 is installed in the space of push broach frame 1; Latch 8 is positioned at the coaxial pilot hole 5 of push broach frame 1, push broach seat 2, contacts with at the bottom of the hole and spring 7 is positioned at stepped hole 6, one ends of push broach frame 1, and the other end contacts with the step of latch; Electromagnet 10 is installed in push broach frame 1 front, its end face is the step locating surface of latch 8, armature 9 and latch 8 one end in contact of electromagnet 10 inside, broaching tool 12 is positioned at the cylindrical hole at push broach seat 2 centers, the top 3 of broaching tool 12 with 4 contact the center of broaching tool 12 afterbody cannelures 11 and the dead in line of latch 8 at the bottom of the cylindrical hole of push broach seat 2.
The explanation of the utility model application process:
At first, broaching tool 12 is put into station, manual operation; Lathe slide plate 13 is come downwards to lower dead center, and so-called lower dead center refers to the set point of downstream station; At this moment, broaching tool 12 shanks have inserted in push broach seat 2 center cylindrical hole, broaching tool top 3 with 4 contact (as shown position) at the bottom of the cylindrical hole, electromagnet 10 energisings, armature 9 is pushing away latch 8 and is overcoming spring force left, inserts in the cannelure 11 of broaching tool 7, and slide plate 13 is up, latch 8 band broaching tools 12 are thereupon to top dead centre, and so-called top dead centre refers to the set point of up terminal; At this moment, manually fill cutter and finish, can carry out automatic operation.
The workpiece of packing into is pressed play button; Slide plate 13 is descending, and this moment, broaching tool 12 was also descending with slide plate 13 under the drive of latch 8; When broaching tool 12 touches workpiece and begins to broach, electromagnet 10 outage, 8 of latches promote the cannelure 11 that armature 9 breaks away from broaching tools 12 and also reset, to lower dead center under the effect of spring 7; Broaching is finished, and slide plate 13 is up, because latch 8 has broken away from the cannelure 11 of broaching tool 7 and resetted, thereby broaching tool 12 is not up with slide plate 13 this moment, thereby breaks away from push broach seat 2, formed can conveniently take out workpiece than large space, slide plate 13 stops uply during to the precalculated position, takes out workpiece; Press play button, slide plate 13 comes again downwards to lower dead center, and this moment, the shank of broaching tool 12 inserted in the cylindrical hole at push broach seat 2 centers, the top 3 of broaching tool 12 with 4 contact at the bottom of the cylindrical hole; At this moment, electromagnet 10 energisings, armature 9 is pushing away latch 8 and is overcoming spring force to left lateral, again inserts in the cannelure 11 of broaching tool 12, and slide plate 13 is up, and latch 8 band broaching tools 12 are accompanied to top dead centre.Once circulation finishes.
Select the diameter of several push broach seat 2 center cylindrical hole, the length of latch 8 is also opposed and should be changed, standard broaching tool tail shape, size, and all the broaching tool 12 of specification all can use.Broaching tool 12 moves up and down distance from the bottom to the top in the cylindrical hole of push broach seat 2.
