Problem.
Detailed description of the invention
The drawings herein are incorporated into the specification and forms part of this specification, and shows and meets implementation of the invention
Example, and be used to explain the principle of the present invention together with specification.
Fig. 1 is upper spraying feed arrangement figure；
Fig. 2 is lower Multifunctional rotary fixture figure.
Specific embodiment
Below in conjunction with attached drawing, technical scheme in the embodiment of the invention is clearly and completely described.
Multifunctional spraying coating device be divided into it is 2 most of, upper spraying feed arrangement shown in FIG. 1 and it is shown in Fig. 2 under it is multi-functional
Rolling clamp.It is upper spraying feed arrangement mainly by can integral elevating rack 11, be fixed on rack 11 spray equipment, spraying fill
The spout 12 set is fixed on the equal composition of grinding wheel 13 of spray equipment end.Lower Multifunctional rotary fixture mainly by workbench 21,
Rotary table top 22, the lower section of rotary table top 22 end face bearing 25, driving motor 23, retarder 24, be fixed on rotary table top 22 3
Pawl sleeve 26, three-jaw sleeve 26 are externally provided with the composition such as high frequency coil 27.Wherein, multiple bearing shell workpiece to be sprayed can (left set in groups
Cylinder and right sleeve) formed it is cylindrical after be put into three-jaw sleeve 26, every group due directly to gravity tightly stacks.
Specific working principle is described below:
(1) it the clamping of workpiece: is automatically positioned and is clamped using three-jaw sleeve, effectively complete the orderly clamping of multiple bearing shells.Rotation
It is disposed with face screw thread on revolving worktable face, three-jaw sleeve can be taken to and along radial feed or exited together, be automatically performed and be put into set
Centering positioning between multiple workpiece of cylinder.
(2) spraying of workpiece: on the one hand, the workpiece after clamping, can be under the driving of driving motor and retarder
Sleeve does principal rotating motion together；On the other hand, upper spray equipment is slowly put into working internal with liftable upper stage.Due to
Only simple relative motion up and down between upper spray equipment and lower three-jaw sleeve, equipment precision that can simply according between
Relative position is carried out to determine.After spraying mouth reaches most three-jaw sleeve bottom, the ascending motion and lower rotation of upper table surface are utilized
The rotary motion of table top can complete spraying mouth to the spraying operation of inner surface of bearing bush.
(3) drying of workpiece: using the high frequency coil being fixedly installed outside three-jaw sleeve, the heating that can complete bearing shell is made
Industry makes spray coated workpiece that can carry out heating, drying operation without secondary movement, and the surface after making spraying is more smooth.It should
Part uses high-frequency heating principle, i.e., first according to Faraday's electromagnetic induction law, when metallic conductor is in a high-frequency alternating electricity
It is internal to generate induced electromotive force in, since the resistance of conductor is small to generate big electric power road.Determined again by joule Lenz
Rule causes kelvin effect, frequency is higher, induced current it is found that alternating magnetic field will make in conductor electric current tend to conductive surface circulation
Density concentrates on the surface of conductor, i.e. kelvin effect is more serious, is brought rapidly up conductive surface.It is different from general high-frequency quenching
, the workpiece heating temperature in the present invention is set in conventional between 100-230 DEG C of bearing shell baking oven, and opposite to quench processing temperature inclined
It is low.
(4) work polishing: when work drying time reach setting value after, using spout lower part setting grinding wheel it is upper
The rotary motion of lower movement and lower rotary table top, can surface effectively to bearing shell carry out polishing operation.The track that it is polished is similar
The honing technique of cylinder makes the roughness value of bearing shell sprayed surface reach OK range.Bearing shell sprayed surface is set to deposit
A small amount of lubricating oil is stored up, the service life of spray coating is increased.
(5) disassembly to work: after rising spray equipment, using the take-up of three-jaw barrel set, work is made to be in pine
Relaxation state, then from facilitating taking-up work between the gap of three-jaw sleeve.
Described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the present invention
In embodiment, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
