Abstract
An improved bamboo hat-typed knife bin relates to a knife change mechanism of a central processing machine, comprises a knife bin, a carriage, a reducer, a motor and a reducer drive axle, can simplify and harmonize smooth acceleration and deceleration, and decreases movement inertia effectively, leading reciprocating movement to be processed stably at high speed and a majority of impact and noise to be eliminated; in particular the disadvantages of low efficiency and time consumption caused by buffering steps needed by traditional mechanism are overcome, thus increasing knife change speed effectively.
Description
One, technical field:
The utility model relates to the umbrella shape cutter storehouse in the processing machine of a kind of center, particularly relates to the umbrella shape cutter storehouse of a kind of reciprocal time weak point, high efficiency.
Two, background technology:
Press, be provided with various cutting tools in the processing machine of center, carry out machining so that after setting procedure, can take suitable cutter in regular turn.It is umbrella shape cutter storehouse that a kind of cutter-exchange mechanism is arranged in the early stage center processing machine, because this umbrella shape cutter storehouse has tool changing advantage reliable, accurate and with low cost, so use till today always.It is that power is back and forth grabbed cutter that pneumatic cylinder is adopted in umbrella shape cutter storehouse, because pneumatic cylinder is difficult for being adjusted to optimal state, so its buffering effect is not good, when being calibrated for buffering when big, before back and forth grabbing cutter long cushion stroke (deceleration time is long) will be arranged, its stroke action time is elongated relatively, thereby influences tool-changing speed, whole working (machining) efficiency is reduced; If when buffering turned down, then reciprocating stroke shortens (deceleration time is short), makes cutter-exchange mechanism easily produce bump, and successively decreases and can not effectively reduce the mobile inertia in cutter storehouse through back cushion effect after a while, so that the error when causing tool changing to grab cutter becomes greatly, influences tool changing.
Back and forth grab the cutter stroke if adopt gear, tooth bar or linkage, then need utilize frequency converter to carry out the acceleration and deceleration action at initiating terminal or anchor point, and the staged acceleration and deceleration hop count of frequency converter is limited, though can reduce impulsive force to mechanism, but still can't high-speed cruising, and its manufacturing cost is higher, obviously is not a desirable mechanism.
In view of this, the inventor is with its rich experiences that manufacture and design for many years to be accumulated of being engaged in associated machines, and analyses in depth research and through long-term endeavour, development and Design goes out the improved umbrella shape cutter of the utility model storehouse finally.
Three, summary of the invention:
The purpose of this utility model promptly is to provide a kind of short umbrella shape cutter storehouse of reciprocal time, to improve its tool changing efficient.
To achieve these goals, the utility model utilizes cutter storehouse, bracing frame, reductor, motor and reductor driving-shaft assembly to constitute a kind of improved umbrella shape cutter storehouse.Top, cutter storehouse is provided with slide, and its each pivot of opening port upper and lower side angle is tied a roller bearing, and the cutter holder pawl is grabbed in common rank knot one bracing frame, front end binding between upper and lower roller bearing; The bracing frame lateral surface is equipped with reductor and links a motor, and the reductor output is connected with driving-shaft assembly and penetrates bracing frame; The slide medial surface is provided with upright rail bar, and its hypomere is an arc location segmental arc; The reductor drive assembly passes bracing frame perforation back string and ties in turn body one end, turn body end is in addition tied in relaying body central hole with the gim peg bolt, the centre bore both sides respectively is provided with a side opening, setting-in one eccentric roller bearing in the side opening of wherein corresponding upright rail bar hypomere location segmental arc outer arc portion, another side opening is setting-in one positive roller bearing then, and two roller bearings are connected to the both sides of upright rail bar respectively.
But tool-changing speed, reduction tool change time also can effectively be improved in the umbrella shape cutter storehouse of said structure except that the level and smooth acceleration and deceleration of simple harmonic quantity and most of impact of elimination and noise.
Be described in further detail below in conjunction with the technical characterictic of specific embodiment the improved umbrella shape cutter of the utility model storehouse.
Four, description of drawings:
Fig. 1 is a decomposing schematic representation of the present utility model.
Fig. 2 is one of combination perspective of the present utility model and action schematic diagram.
Fig. 3 is two of an action schematic diagram of the present utility model.
Fig. 4 is three of an action schematic diagram of the present utility model.
Five, the specific embodiment:
With reference to shown in Figure 1, the improved umbrella shape cutter of the utility model storehouse mainly is made of cutter storehouse 1, bracing frame 2, reductor 3, motor 4 and driving-shaft assembly 5.The top in cutter storehouse 1 is provided with a slide 12, and slide 12 opening port upper and lower side angles are located each pivot and had roller bearing 13,14, the bracing frame 2 of 13,14 common rank knot one riser shapes of upper and lower roller bearing; The lateral surface of bracing frame 2 is equipped with reductor 3 and links has motor 4, reductor 3 outputs to be connected with driving-shaft assembly 5 and to penetrate bracing frame 2; Slide 12 medial surfaces are provided with upright longitudinally rail bar 15, its hypomere is the location segmental arc 151 of arc, reductor 3 driving-shaft assemblies 5 pass perforation default on the bracing frame 2 21 back strings and tie in an end of sheet turn body 30, the other end of turn body 30 is then tied centre bore 320 places in a sheet of relaying body 32 with gim peg 31 bolts, wing position, centre bore 320 both sides respectively is provided with a side opening 321,322, side opening 321 setting-ins one eccentric roller bearing 33 corresponding to upright rail bar 15 hypomeres location segmental arc 151 outer arc portions, 322 setting-ins of another side opening, one positive roller bearing 34, eccentric roller bearing 33 and positive roller bearing 34 are connected to the both sides of upright rail bar 15 respectively.
With reference to figure 2, Fig. 3 and Fig. 4, bracing frame 2 front-end A can be installed and grab cutter holder pawl (not shown), and during reciprocating action, eccentric roller bearing 33 utilizes its eccentric potential difference that one precompressed effect is provided, to eliminate the drive gap that may cause vibration.Transmission along with reductor 3, make turn body 30 return back to 90 °, 180 ° positions successively by 0 °, the upright rail bar 15 in 32 edges of relaying body moves and makes slide 12 and grabs the cutter holder pawl and advance, and finishes 1/2 stroke of reciprocating action, then counteragent is promptly finished in addition 1/2 stroke and is set back.Wherein, when location segmental arc 151 places of upright rail bar 15 lower ends of passing through, can make and grab the cutter accurate positioning and grab cutter (tool changing) program.
By the structure in above-described improved umbrella shape cutter storehouse as can be known, but the acceleration and deceleration smoothly of the utility model simple harmonic quantity effectively reduce movement inertia, make to move back and forth high-speed smooth and carry out and eliminate most impact and noise; Particularly importantly, can overcome traditional mechanism and need carry out step of buffering and cause efficient not high, time-consuming shortcoming effectively improves tool-changing speed.Test confirms, the reciprocal time during this mechanism tool changing only is 1.5 seconds, improves more than the several times than traditional mechanism, has effectively shortened tool change time.
In sum, the utlity model has stronger practicality and higher industrial utilization, be to propose patent application in accordance with the law, would like to ask the examination and approval early of an ancient unit of weight office.
