Abstract

The utility model provides a spiral type guide sleeve structure without oil feeding, which is characterized in that a spiral type continuous groove is respectively milled on the inner and the outer surfaces of the guide sleeve, and molybdenum disulphide (MoS2) is buried in the groove; thereby, the contact surface of a guide post and the guide sleeve can be increased and be uniform, and the efficiency of lubrication and fluent actuation is achieved. An inner hole of the guide sleeve is ground and precisely honed, the outer diameter of a cylinder is ground, therefore the proper circle of the inner hole and the concentricity of inside and outside can be obtained exactly. The utility model has the advantages of simple structure, integral forming, convenient installation and assemblage, uniform lubrication, fluent movement and high work efficiency.

Description

Screw type does not have the structure of oil supply guide pin bushing

＜one〉technical field:

The utility model is relevant with the structure of guide sleeve device, mainly is generally to commonly use the use drawback of guide pin bushing, does an improvement and makes it more perfect, more detailed it, refer to that especially convenient the and screw type that start is smooth and easy of a kind of manufacturing do not have the structure of oil supply guide pin bushing.

＜two〉background technique:

The guide pin bushing structure that occurs on the market in the past, as shown in Figures 1 and 2, it makes this tradition does not have oil supply guide pin bushing structure when manufacturing, and is milled with the hole slot 11 of discontinuous on its guide pin bushing 10, buries molybdenum disulfide (MoS2) in the hole slot 11 of discontinuous underground, itself can't contact molybdenum disulfide (MoS2) with guide pillar fully, cause lubricated inequality, start has some setbacks, so that causes manufacturing efficiency not high, the market competitiveness reduces, and economic profit reduces relatively.

＜three〉summary of the invention:

A kind of screw type of the utility model does not have the structure of oil supply guide pin bushing, its main purpose is to utilize the guide sleeve device structure Design of the utility model, reach and make the quick start purpose smoothly that reaches, and the drawback of commonly using guide pin bushing is improved, the value that provides industrial circle to utilize makes it to have economic benefit.

A kind of screw type of the utility model does not have the structure of oil supply guide pin bushing, be primarily characterized in that: all mill out a screw type continuous channel on the inside and outside surface of this guide pin bushing, in this groove, bury molybdenum disulfide (MoS2) underground, by this, make guide pillar be in contact with it that face increases and average, and reach lubricated and start effect smoothly.

Wherein, after this guide pin bushing endoporus ground, precision was bore and grinded and is imposed cylinder again and grinds external diameter again, definitely reaches endoporus proper circle and with one heart inside and outside.

A kind of screw type of the utility model does not have the structure of oil supply guide pin bushing, and its advantage is:

1, simple for structure, one-body molded, process easy to assembly.

2, lubricated evenly, move smooth and easy, high working efficiency.

＜four〉description of drawings:

Fig. 1 commonly uses the three-dimensional cross-sectional schematic of guide pin bushing.

Fig. 2 A commonly uses vertical cross-sectional schematic of guide pin bushing.

Fig. 2 B commonly uses the horizontal cross-sectional schematic of guide pin bushing.

The three-dimensional cross-sectional schematic of Fig. 3 the utility model.

Vertical cross-sectional schematic of Fig. 4 A the utility model.

The horizontal schematic side view of Fig. 4 B the utility model.

Enforcement view after the guide pillar of Fig. 5 the utility model enters.

Number in the figure is as follows:

10 guide pin bushings, 11 hole slots, 20 grooves, 30 guide pillars

＜five〉embodiment:

See also Fig. 3 to shown in Figure 5, a kind of screw type of the utility model does not have the structure of oil supply guide pin bushing, be primarily characterized in that: all mill out a screw type continuous channel 20 on the inside and outside surface of this guide pin bushing 10, in this groove 20, bury molybdenum disulfide (MoS2) underground, by this, make guide pillar 30 be in contact with it that face increases and average, and reach lubricated and start effect smoothly.

When assembling was implemented, it was extremely shown in Figure 5 to continue to consult Fig. 3, makes because of guide pin bushing 10 of the present utility model is formed in one, not only very quick on processing procedure, and cooperated the combination of this guide pillar 30, can finish entire combination very easily.

During concrete enforcement, a kind of screw type of the utility model does not have the structure of oil supply guide pin bushing, the spiral continuous channel 20 that mills out inside and outside its guide pin bushing 10, and in groove 20, bury molybdenum disulfide (MoS2) underground, after endoporus grinds, precision is bore and grinded and is imposed cylinder again and grinds external diameter again, definitely reaches endoporus proper circle and with one heart inside and outside; What deserves to be mentioned is, after the groove 20 of the utility model is buried molybdenum disulfide (MoS2) underground with spiral design,, will make lubricated more smooth and easyly, also more can improve its lubricating efficiency because its surface of contact increases and be average; Because molybdenum disulfide (MoS2) can initiatively provide lubricated effect, make the frictional heat production few, and heat dissipation rate is fast, so the sintering that the punch press operation that can prevent to run up is produced is bitten phenomenon, can significantly improve the working life of mould.

Claims

1, a kind of screw type does not have the structure of oil supply guide pin bushing, it is characterized in that: all mill out a screw type continuous channel on the inside and outside surface of this guide pin bushing, bury molybdenum disulfide underground in this groove.
