The manufacture of the self-lubricating bearing is carried out at home and abroad by artificially inlaying graphite cylindrical particles. Generally, the graphite cylindrical particles are coated with epoxy resin glue by manpower, and then the graphite cylindrical particles are embedded into graphite holes of a copper-based shaft sleeve workpiece by manpower. In recent years, the domestic research and development of automatic assembling machines for self-lubricating bearings are involved, for example, in chinese patents, the patent application No. 201821527246.4 discloses an automatic glue dispensing device for gluing graphite holes of workpieces of self-lubricating bearing sleeves, the patent application No. 201821529039.2 discloses a two-component automatic glue dispensing device for graphite holes of workpieces of self-lubricating bearing sleeves, and the patent application No. 201821529037.3 discloses a creeping type glue dispensing device for graphite holes of workpieces of self-lubricating bearing sleeves. The glue dispensing head sprays the inner wall of the graphite hole through the glue dispensing hole, and the uniformity of glue coating is poor; in addition, when the glue is sprayed, the glue dispensing head must stay in the graphite hole, and the working efficiency is low.

In order to solve the technical problem, the utility model provides a technical scheme as follows: a multi-empty elastic dispensing head for automatically gluing a graphite hole of a self-lubricating bearing comprises the multi-empty elastic dispensing head. The surface of the multi-cavity elastic dispensing head is a multi-cavity elastic soft structure surface layer which is in contact with the graphite holes of the self-lubricating bearing to glue the inner wall of the corresponding graphite hole.
Further, the multi-empty elastic dispensing head is made of one material or multiple materials.
Furthermore, the overall dimension of the multi-hollow elastic dispensing head is larger than the dimension of a graphite hole of the self-lubricating bearing.

Compared with the prior art, the utility model relates to a many empty elasticity dispensing head for self-lubricating bearing graphite hole automatic gluing's advantage lies in: when glue is injected, glue is firstly injected into the surface layer of the multi-empty elastic soft structure on the surface of the multi-empty elastic dispensing head, so that when the multi-empty elastic dispensing head is injected with glue, the multi-empty elastic dispensing head can not stay in the graphite hole, the dispensing time can be shortened, and the working efficiency is improved. In addition, the surface layer of the multi-cavity elastic soft structure is in contact with the graphite hole of the self-lubricating bearing to glue the inner wall of the corresponding graphite hole, so that the contact area can be increased, and the glue can be uniformly smeared.
Drawings
Fig. 1 is a schematic structural diagram of a multi-empty elastic dispensing head for automatically gluing graphite holes of a self-lubricating bearing in the embodiment, which adopts two materials.
In the figure, a multi-hollow elastic dispensing head 100, a dispensing head inner core 110, a dispensing hole 110a and a multi-hollow elastic soft structure surface layer 120 are shown.
DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
The present invention will be described in further detail with reference to the following drawings and examples, wherein the specific examples are provided for illustration only and are not intended to limit the present invention.
As shown in fig. 1, the multi-empty elastic dispensing head for automatically gluing the graphite holes of the self-lubricating bearing is preferably made of two materials. The multi-space elastic dispensing head 100 comprises a dispensing head inner core 110 and a multi-space elastic soft structure surface layer 120. A porous, resilient, soft structural skin 120 overlies the dispensing head core 110. The dispensing head inner core 110 is a hollow structure. The dispensing hole 110a is opened at the front end of the dispensing head inner core 110, the glue in the dispensing head inner core 110 is injected into the multi-space elastic soft structure surface layer 120 through the dispensing hole 110a, and the multi-space elastic dispensing head 100 enters the graphite hole of the self-lubricating bearing workpiece under the pushing of the dispensing driving unit. The outer diameter of the porous elastic dispensing head 100 is larger than the aperture of the graphite hole, so that the porous elastic soft structure surface layer 120 can uniformly coat glue on the inner wall of the corresponding graphite hole under the extrusion of the graphite hole.
The dispensing head core 110 is generally made of a rigid material such as plastic or metal. The material of the porous elastic soft structure surface layer 120 may be made of porous sponge, or porous latex, or porous EVA, or porous PVA collodion, or porous rubber, or porous silica gel, or a novel porous elastic soft material.
The multi-gap elastomeric dispensing head 100 may be cylindrical or non-cylindrical in shape. The front end of the multi-space elastic dispensing head 100 generally adopts a guide structure with the size from small to large.
The dispensing head core 110 may be made of the same material as the porous elastomeric soft structural skin layer 120, such that the porous elastomeric dispensing head 100 is an integral part.
The utility model relates to a many empty elasticity dispensing head for self-lubricating bearing graphite hole automatic gluing's advantage lies in: glue is firstly injected into the multi-empty elastic soft structure surface layer 120 on the surface of the multi-empty elastic dispensing head 100 before glue injection, so that when the multi-empty elastic dispensing head 100 is subjected to glue injection, the multi-empty elastic dispensing head 100 can inject glue in the process of replacing one graphite hole with another graphite hole without stopping in the graphite hole, and therefore glue injection time can be shortened and work efficiency is improved. In addition, the porous elastic soft structure surface layer 120 coats the inner wall of the corresponding graphite hole by contacting with the graphite hole of the self-lubricating bearing, and the contact area can be increased, so that the glue is more uniformly coated.
The specific embodiments described herein are merely illustrative of the spirit of the invention; various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
