Abstract
The invention relates to a dynamic sealing device for a single shaft of a casting mold numerical control machine. A metal cover and an organ cover are combined, and a double-layer protective mode is adopted, thus an excellent dust-proof effect can be achieved. In the device provided by the invention, components such as a guide rail, a screw rod and the like through which dust can invade the interior of a motive system are omitted, and the service life of the device is improved; and the device has the advantages of simplicity and convenience in installation, convenience in maintenance, capability of adapting to the severe environment with high content of dust, and the like.
Description
Technical field
The present invention relates to be used for the construction and device of the moving system sealing and dustproof of casting mold processing, belong to the non-traditional machine tool field of accessories.
Background technique
Sealing is to prevent fluid or the measure of solid particle from leaking and prevent the precision parts in the intrusion machinery equipments such as introduced contaminants such as dust and moisture between adjacent junction plane.Its basic demand be good airproof performance, safe and reliable, the life-span is long, should make every effort to compact structure, system is simple, makes easy to maintenance, with low cost.
Motive sealing at present can be divided into rotary seal and two kinds of fundamental types of reciprocation sealing.But in the structure of all moving system sealing, mostly be the sealing between axle and the hole, this motion is for rotatablely moving, or is short-range cylindricality to-and-fro motion.Seldom relate to than the sealing between the linear reciprocating motion component of big stroke.At present in the sealing configuration form of the linear reciprocating motion of big stroke, have only simple organ bell-type sealing or steel-belt type sealing.In the casting mold course of working, produce a large amount of antiquated sands that splashes and cutting dust, can not reach good dust sealing effect in this simple sealing means process, can not satisfy usage requirement.
Summary of the invention
Purpose of the present invention is exactly at the existing casting mold processing existing deficiency of straight-line motion mechanism sealing technique, and the device of the single shaft motion sealing that is used for the casting mold numerical control machine tool of two kinds of complex forms is provided, and concrete form is as follows:
The dynamic seal apparatus that is used for the single shaft of casting mold numerical control machine tool comprises the pedestal that leading screw, guide rail can be housed, and the top that constitutes enclosed space with pedestal has the metal covering of the elongated slot that can move around for slide block, the organ cover that links to each other with slide block.
The organ cover can with pedestal constitute confined space metal covering above, fully metal covering is covered;
The organ cover also can be below metal covering, and metal covering covers the organ cover;
The sealing device can also comprise steel band, and steel band passes on the elongated slot that slide block covers metal covering;
Metal covering can link to each other with pedestal with sunk screw, and periphery is shut with sealer;
Metal covering can be provided with flanging, and the bottom of organ cover is encased;
The elongated slot of metal covering is provided with different quantity according to the width of metal covering;
Metal covering have elongated slot near stiffening rib is set or the thickness of metal covering is thickeied to 2mm;
Single shaft motion seal arrangement of the present invention constitutes the space of two-layer relative closure on total, formed double-deck protection, can effectively stop the invasion of dust, reach the protection of moving systems such as leading screw, guide rail, the very little even not friction of friction between self component at the volley of described sealing protective device has long service life, and is easy for installation, safeguard advantages such as simple, and can satisfy the requirement of in the rugged environment that sand and dust fly upward, working.

Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments:
Be used for the dynamic seal apparatus of the single shaft of casting mold numerical control machine tool, it is characterized in that, this device is made up of pedestal 1, guide rail 2, dustproof construction and slide mechanism etc.Described dustproof construction is made up of metal covering 4 and organ cover 5, pedestal 1 maintains static, guide rail 2 is fixed on the pedestal 1, and slide block 3 is formed sliding pair with guide rail 2, and contiguous block 6 links to each other with guide rail, realize contiguous block 6 along guide rail 2 direction to-and-fro motion, one side of described organ cover links to each other with pedestal 1, and a side links to each other with contiguous block 6, and the organ cover can carry out free shrink along with moving around of contiguous block, described metal covering 4 is fixing with pedestal 1, and periphery is all shut with pedestal is airtight.Described dust sealing device comprises two kinds of combining forms, first kind: dustproof construction is made up of organ cover 5 and metal covering 4, organ cover 5 is following, metal covering 4 is last, described metal covering 4 can intercept a large amount of dust outside, a spot of dust enters between metal covering 4 and the organ cover 5, and can walk around the dust that the organ bottom is advanced into protecting component inside on circling round does not at last almost have; Second kind: dustproof construction is made up of organ cover 5 and metal covering 4, metal covering 4 is following, organ cover 5 is last, most dust intercepts outside organ cover 5, low amounts of dust can enter between organ cover 5 and the metal covering 4 from organ cover bottom, since self gravitation effect, fall after rise in the Vertical Channel of most dusts between organ cover 5 and metal covering 4, can walk around Vertical Channel at last and can almost not have by the dust that steel band protection enters protecting component inside;
Connecting plate 11 has flat mouthful in the position concordant with metal covering 4, and inside has steel band 10 to pass; Described steel band 10 overlaps with the slotting position of metal covering, the fluting overwhelming majority of metal covering 4 is sealed by steel band 10 like this, the quantity of steel band and elongated slot can be adjusted (is 1,2,4 etc. as the quantity of elongated slot) according to the structure of the width of metal covering 4 and inner contiguous block 6, be accompanied by the increasing of quantity of elongated slot, the opening area of elongated slot can reduce thereupon, has effectively stopped entering of dust.
Metal covering adds stiffening rib 12 on the internal structure of metal covering under the thin situation of thickness of slab.
Servomotor 9 drives leading screws 8 rotations, rotatablely moving of leading screw can be converted into straight line motion with leading screw 8 nut engaged 7 and drive slide blocks 6 to move around along the direction of guide rail 2; Slide blocks 6 drives organ cover 5 simultaneously and (descend) free back and forth convergent-divergent on stainless steel cage 4; In the whole process between inside and the outside, organ cover, metal covering and pedestal form two relative enclosed spaces, form double-deck protection, can keep the cleaning, pollution-free of inner body.
In sum, the present invention can be splashed seriously at the scrap particle, dust concentration is high, work under the environment of inclement condition, has the reliability height, and is easy for installation, characteristics such as easy maintenance.
More than be schematically to the description of the present invention and mode of execution thereof, do not have restricted.So, if those of ordinary skill in the art is enlightened by it, under the situation that does not break away from the invention aim, carry out other embodiments, all should belong to protection scope of the present invention.
