Abstract
The utility model provides a pneumatic float support mechanism used for aluminum casting machining. The pneumatic float support mechanism includes a float support body and a support rod, wherein a spring mounting cover is fixed on the float support body; the spring mounting cover is buckled and connected with the lower end of the support rod; a long spring is accommodated inside the support rod; two ends of the long spring are propped between the spring mounting cover and the support rod; the float support body is further provided with a press plate; one end of the press plate is rotationally connected with the float support body through a hinge pin; two sides of the other end of the press plate are propped against one end of the spring and a top head respectively; the other end of the spring is propped against the float support body; the top head is mounted on a piston of a locking cylinder; and further, when the piston of the locking cylinder extends out, the press plate presses the support rod sidewards. The pneumatic float support mechanism has the advantages of simplicity and compactness in structure, economy and practicability, and excellent support function during aluminum casting machining.
Description
Technical field
The utility model relates to a kind of pneumatic over draft mechanism, especially a kind of pneumatic over draft mechanism that is used for aluminium casting processing.
Background technology
In machining, often need the air-actuated jaw of Design and Machining aluminium casting, some working position at workpiece in design need add the over draft support.Though the pneumatic over draft cylinder of standard is arranged now, because price is higher, the client is difficult to bear, and this just requires us to design a kind of is the practical again pneumatic over draft structure of economy.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art, and a kind of pneumatic over draft mechanism that is used for aluminium casting processing is provided, and workpiece is provided add the over draft support.
The technical scheme that provides according to the utility model; The said pneumatic over draft mechanism that is used for aluminium casting processing; Comprise over draft body and support bar, be fixed with the spring mounting cover on the said over draft body, the spring mounting cover is connected with support bar lower end buckle; Hold long spring in the support bar, said long both ends of the spring is against between spring mounting cover and the support bar; Also be provided with pressing plate on the said over draft body; One end of pressing plate is rotationally connected through joint pin and over draft body; The both sides of the pressing plate other end prop up an end and the top of spring respectively, and the said spring other end props up the over draft body, and said top is installed on the piston rod of locking cylinder; When the piston rod of locking cylinder stretches out, said pressing plate compresses the support bar side direction.
Be lined with circlip between said spring mounting cover and the over draft body.
Be with dust ring on the said support bar.
Said supporting bar top is fixed with the over draft head.
Said over draft body side surface is equipped with cover plate, and locking cylinder is installed on the said cover plate.
The utility model has the advantages that: simple and compact for structure, economical and practical, in aluminium casting processing, good supporting role is provided.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A profile of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Like Fig. 1; Shown in 2: the pneumatic over draft mechanism that is used for aluminium casting processing; Comprise over draft body 9 and support bar 1, it is characterized in that: be fixed with spring mounting cover 12 on the said over draft body 9, spring mounting cover 12 is connected with support bar 1 lower end buckle; Hold long spring 11 in the support bar 1, said long spring 11 two ends are against between spring mounting cover 12 and the support bar 1; Also be provided with pressing plate 6 on the said over draft body 9; One end of pressing plate 6 is rotationally connected through joint pin 8 and over draft body 9; The both sides of pressing plate 6 other ends prop up an end and top 4 of spring 3 respectively, and said spring 3 other ends prop up over draft body 9, and said top 4 is installed on the piston rod of locking cylinder 5; When the piston rod of locking cylinder 5 stretches out, said pressing plate 6 compresses support bar 1 side direction.Said support bar 1 top is fixed with over draft 14.Said over draft body 9 sides are equipped with cover plate 7, and locking cylinder 5 is installed on the said cover plate 7.
As shown in Figure 2, be lined with circlip 13 between said spring mounting cover 12 and the over draft body 9.Be with dust ring 10 on the said support bar 1.
This pneumatic over draft structure adopts support bar 1 long spring 11 freely to stretch, and can move to the correct position of workpiece pressing according to the workpiece shape automatically, produces coupling mechanism force locking support bar 1 by locking cylinder 5 at last, when cutting, plays a supporting role.
Concrete operating principle is following: behind workpiece 15 location; Over draft this moment 14 is fixed on the support bar 1, because the elastic force effect of 11 pairs of support bars 1 of long spring, makes over draft 14 and workpiece 15 keep in touch state; The main cylinder that clamps clamps earlier; Workpiece 15 is supported in the supporting, and workpiece 15 mobile makes over draft 14 also corresponding moving, under long spring 11 effects all the time with workpiece 15 surperficial contacts.After the main clamping cylinder clamping; Locking cylinder 5 piston rods stretch out action makes 4 pairs of pressing plates in top 6 produce thrust; Pressing plate 6 produces the side direction thrust around joint pin 8 rotation to support bar 1, thereby 1 can not make a concession adding the man-hour support bar, effectively plays the supplemental support effect to workpiece 15.
