CN106391377A - Automatic positioning method for spray gun of spray workshop - Google Patents

Abstract

The invention discloses an automatic positioning method for a spray gun of a spray workshop. The automatic positioning method includes the following steps that firstly, a scale ruler and a spray gun angle ruler are additionally arranged at the outer portion of a spray gun reciprocator; secondly, parameters of the gun position and the angle of the spray gun are recorded in the process of spraying of each kind of wheel type; thirdly, the numerical value records of the gun position and the angle are input to an equipment system, and therefore a parameter value for controlling the gun position and the angle is added in equipment; and fourthly, when the wheel type is switched, the gun position parameter of the corresponding wheel type is selected manually, and gun position adjustment is automatically completed through the equipment. By the adoption of the above technical scheme, according to the automatic positioning method for the spray gun of the spray workshop, a worker can quantize the gun position and the angle of the spray gun for each kind of wheel type, the parameters are fixed, and therefore the fixed gun position and the fixed angle are used during spraying; and when the wheel type is switched, the gun position parameter of the corresponding wheel type is selected manually, gun position adjustment can be automatically completed through the equipment, and the phenomenon that sprayed appearances are not consistent when different online workers adjust the gun position of the spray gun manually is avoided.

Description

A kind of painting workshop spray gun automatic positioning method

Technical field

The present invention relates to a kind of painting workshop spray gun automatic positioning method, belong to automotive hub production process equipment technology neck Domain.

Background technology

Aluminium alloy wheel hub is so that it is elegant in appearance, safety and comfort the features such as won the favor more carrying out many private car owners.Now, Almost all of new model all employs aluminium alloy wheel hub.The manufacture method of aluminium alloy wheel hub include multiple, wherein, low pressure casting The most basic method producing aluminium alloy wheel hub, also both economical it is simply that molten metal is cast in mould molding hard Change；Counter pressure casting is relatively advanced casting method, and the suction being produced with fine vacuum, metal inspiration mould, is conducive to keeping permanent Gentle despumation, does not have pore and even density, intensity is very high in foundry goods；Forging is the most advanced of manufacture aluminium alloy wheel hub Method, with the pressure of 62.3MN one block of aluminium ingot in hot state, be pressed into a wheel hub, this aluminium alloy wheel hub strong Degree is 3 times of general aluminium wheels, and the former is also lighter by 20% than the latter.After casting aluminium alloy wheel hub or forging molding, it is Avoid easily corroding in moist atmosphere, typically will be surface-treated.At present, automotive hub is typically sprayed using paint Apply, go up metallic paint again after needing first under-coating varnish after automobile wheel hub surface cleaning, finally go up finishing varnish again, need to spray through three roads Apply operation, and spraying coating process is higher to the spraying technology requirement of spraying workman.The application of wheel be by air cannon, static gun and Rotation cup completes jointly, wherein controls the parameter of these spray guns to have a lot, and most parameters include telling paint amount, air pressure, quiet Piezoelectric voltage, electric current etc. are all that PLC directly controls, and the position of only spray gun manually adjusts, therefore not only fixed every time Position is all inaccurate, and manuallys locate less efficient.

Content of the invention

Therefore, it is an object of the invention to overcoming defect of the prior art, provide a kind of painting workshop spray gun automatically fixed Method for position.

To achieve these goals, a kind of painting workshop spray gun automatic positioning method of the present invention, comprises the following steps：

1）Outside in spray gun reciprocating engine increases graduated scale and angle of gun scale；

2）Record position of lances and angle parameter during spraying each wheel-type；

3）Rifle position and angular values record are input in the middle of device systems, thus equipment increases by one controls rifle position and angle Parameter value；

4）When switching wheel-type, the rifle position parameter of the corresponding wheel-type of artificial selection, equipment will be automatically performed rifle position adjustment.

Using technique scheme, the painting workshop spray gun automatic positioning method of the present invention, each can be taken turns by operator Type spray gun rifle position and angular quantification, and preset parameter, thus robbing position and angle in spraying using fixing, when switching wheel-type When, the rifle position parameter of the corresponding wheel-type of artificial selection, equipment will be automatically performed rifle position adjustment, it is to avoid different online assignment employee's handss During dynamic adjustment position of lances, spraying outward appearance is inconsistent.

Specific embodiment

Below by way of specific embodiment, the present invention is described in further detail.

The present embodiment provides a kind of painting workshop spray gun automatic positioning method, comprises the following steps：

1）Outside in spray gun reciprocating engine increases graduated scale and angle of gun scale；

2）Record position of lances and angle parameter during spraying each wheel-type；

3）Rifle position and angular values record are input in the middle of device systems, thus equipment increases by one controls rifle position and angle Parameter value；

4）When switching wheel-type, the rifle position parameter of the corresponding wheel-type of artificial selection, equipment will be automatically performed rifle position adjustment.

Using technique scheme, the painting workshop spray gun automatic positioning method of the present invention, each can be taken turns by operator Type spray gun rifle position and angular quantification, and preset parameter, thus robbing position and angle in spraying using fixing, when switching wheel-type When, the rifle position parameter of the corresponding wheel-type of artificial selection, equipment will be automatically performed rifle position adjustment, it is to avoid different online assignment employee's handss During dynamic adjustment position of lances, spraying outward appearance is inconsistent.

Obviously, above-described embodiment is only intended to clearly illustrate example, and the not restriction to embodiment.For Change or the change of other multi-forms for those of ordinary skill in the art, can also be made on the basis of the above description Dynamic.There is no need to be exhaustive to all of embodiment.And the obvious change thus extended out or change Move among still in the protection domain of the invention.
