Abstract
The utility model relates to a grease injecting head for a crawler-type pin shaft. The grease injecting head comprises two polyurethane blocks, two semi-circular conical sleeves and a flange; wherein the polyurethane blocks are fixed on the conical sleeve by a bolt; the rear end of the conical sleeve is connected on the flange by a bolt; the combination surface of the two conical sleeves are connected by a spring; a metal pipe is arranged in a grease injection hole of the conical sleeves in a form of interference fit; the metal pipe extends into polyurethane block counter-bores; guide holes connected with the polyurethane block counter-bores and pin holes are arranged in the polyurethane blocks. The grease injecting head is simple in structure, reliable in property, good in sealing effect and long in service life; with the adoption of the grease injecting head to inject the grease, the grease is inexistent at both ends of the pin, in this way, the service life of the crawler is greatly prolonged.
Description
Technical field
The utility model relates to crawler bearing pin grease filling machine field, especially a kind of greasing head that is applied in the crawler bearing pin grease filling machine.
Background technique
Crawler bearing pin grease filling machine is a kind ofly to be injected into the equipment between pin and the guide to grease, and it mainly comprises greasing pump, grease pouring valve and greasing head.Crawler belt bearing pin grease filling machine is when work; Only need be placed on crawler belt bearing pin and axle sleeve on the feed slideway; Machine can be got crawler belt bearing pin and axle sleeve automatically and bearing pin and axle sleeve are fitted together, and in the gap of crawler belt bearing pin and axle sleeve, injects the oil quantity of setting then.The sealing of greasing head is relatively poor at present, and after grease filling machine had been annotated grease, the pin two ends had a large amount of greases, had had a strong impact on the life-span of crawler belt.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the above-mentioned existing technology, and the crawler bearing pin greasing head of a kind of simple in structure, reliable performance, good sealing effect is provided.
The technological scheme of the utility model is:
A kind of crawler bearing pin greasing head; It is characterized in that: comprise two polyurethane blocks, two semicircle tapered sleeves and a flange plate, polyurethane block is fixed by bolts on the tapered sleeve, and the rear end of tapered sleeve is connected on the flange plate with bolt; Adopt spring to connect between the junction plane of two tapered sleeves; Interference fit is installed a metal tube in the greasing hole of tapered sleeve, and this metal tube reaches in the polyurethane block counterbore, makes the pod apertures of a connection polyurethane block counterbore and pinhole in the polyurethane block.
And described metal tube outside coaxial package one is used for the rubber washer of sealed metal tube and polyurethane block counterbore.
And described flange plate is connected on the oil cylinder head of grease filling machine through spring and screw.
The utlity model has following advantage and good effect:
When 1, two tapered sleeves in this greasing head were closed, two polyurethane blocks had a contour projector, therefore can constitute the space of a sealing with guide, and this moment, grease was pressed onto in the pin guide through the greasing hole under pressure.
2, tapered sleeve greasing hole of this greasing head and metal tube interference fit, metal tube reaches in the polyurethane block counterbore, rubber washer and metal tube interference fit; Rubber washer is forced in the counterbore of polyurethane block; Connect through bolt, rubber washer is extruded, and has so just constituted the space of a sealing.
3, adopt spring to connect between the two tapered sleeve junction planes of this greasing head, flange plate adopts spring, screw to be connected with the oil cylinder head.Polyurethane block can constitute the space of a sealing with guide during greasing, guarantees oil-proof; Separately, pin can be inserted between the polyurethane block two tapered sleeves very smoothly during greasing next time under the spring force effect under the normal state.
4, the utility model be a kind of simple in structure, volume is little, reasonable in design, reliable performance, long service life, cost is low and the extraordinary crawler bearing pin of sealing greasing head; Use the pin two ends after the greasing of this greasing head not have grease, greatly prolonged the working life of crawler belt.

Embodiment
Be described in detail the embodiment of the utility model below in conjunction with accompanying drawing; Need to prove that present embodiment is narrative, is not determinate, can not limit the protection domain of the utility model with this.
A kind of crawler bearing pin greasing head; Comprise two polyurethane blocks 1, two semicircle tapered sleeves 3 and flange plate 4; Polyurethane block is fixed by bolts on the tapered sleeve; The rear end of tapered sleeve is connected on the flange plate with bolt, and flange plate is connected to through spring and screw on the oil cylinder head of grease filling machine, adopts spring 7 to connect between the junction plane of two tapered sleeves.
Interference fit is installed a metal tube 5 in the greasing hole 6 of tapered sleeve, this metal tube outside co-axial seal suit one rubber washer 2, and this rubber washer is used for sealed metal tube and polyurethane block counterbore between tapered sleeve and polyurethane block.Metal tube reaches in the polyurethane block counterbore 9, makes the pod apertures 8 of a connection polyurethane block counterbore and pinhole in the polyurethane block.
The working procedure of the utility model is:
Tapered sleeve halts when sealing block touches guide along with oil cylinder advances during greasing.Spring between this moment flange plate and the oil cylinder, the spring between two tapered sleeves also in the raw.Oil cylinder moves on, and the spring between flange plate and the oil cylinder, the spring between two tapered sleeves begin compression, and tapered sleeve has certain angle of inclination, so two tapered sleeve junction planes can auto-closing.When two polyurethane blocks were compressed and constitute the space of a sealing with guide, oil pump was started working, and the greasing time one of setting arrives, and the greasing action finishes.Oil cylinder is return, and separately, pin can be inserted between two polyurethane blocks two tapered sleeves very smoothly during greasing next time under the effect of spring force.So just can guarantee that the pin two ends of having annotated fat do not have grease.
