Description
Technical field
The present invention relates to a kind of open and close control valve, relate in particular to the coolant control valve door that prevents the cooling liquid obstruction that a kind of tooth bar automation grinding that is applied to the fluid-link steering machine is used.
Background technique
At present; In each tame auto parts and components manufacturing enterprise; In the fluid-link steering machine tooth bar course of working to one of key component of its fluid-link steering machine assembly; Extensively adopted a kind of automation grinding technique, the automation grinding technique is the key areas in the advanced manufacturing technology, is to realize High-speed machining, precision machining, the most effective, the most widely used basic technology technology of ultraprecise processing in the modern mechanical manufacturing.
When the automation grinding of fluid-link steering machine tooth bar, when automatic charging operation or automatic blanking operation, need close the supply of cooling liquid, and before to the tooth bar grinding process, must in time open cooling liquid.Because when the tooth bar grinding; Cooling liquid must be arranged to the tooth bar workpiece and the equipment for grinding that is in contact with it fully cools off and lubricated, like the supply of no cooling liquid, can the generation dry abrasive cutting between tooth bar workpiece and the equipment for grinding; And this kind dry abrasive cutting meeting damages the emery wheel of tooth bar workpiece and equipment for grinding; When serious even possibly directly damage lathe, have to equipment is carried out shutdown maintenance, greatly reduce manufacturing efficiency.
We find in actual production process, and the main cause that above-mentioned cooling liquid does not have supply condition is described below:
Because the particularity of fluid-link steering machine tooth bar processing; Common liquid in-out valve can't directly be used for this fluid-link steering machine tooth bar manufacture field, and the sand grains of the emery wheel of equipment for grinding was constantly coming off when reason just was grinding, and the metal granule of the powdery that grinds can't filter out fully; Make the sand grains that some are trickle and the metal granule of powdery be blended in the cooling liquid; Cooling liquid is when recycling, and is as shown in Figure 1, and the metal granule that the barrier film pressure balance type Electromagnetic Control valve that existing technology adopts can cause trickle sand grains and powdery is in the pressure balance chamber interior of electromagnetic action deposit at valve; Make valve blocked; Cause cooling liquid to supply with, thereby cause dry abrasive cutting, and maybe follow-up possible manufacturing mechanism damage, problem such as shutdown.
As shown in Figure 2; Through the barrier film pressure balance type Electromagnetic Control valve under the present technology is done further analysis, we find that it causes cooling liquid to supply with, and causes the reason of dry abrasive cutting; Relevant with the body structure of valve under the existing technology, its concrete reason is described below:
The steel of the valve under the existing technology silently is fixed together through contiguous block and rubber diaphragm separator.A pressure release aperture is arranged on the contiguous block.There is pressure release aperture rubber the spool underpart silently.Spool couples together through connecting spring or extension spring and contiguous block.A pressure compensation opening is arranged on the rubber diaphragm separator, water-inlet cavity and pressure equalizing chamber are connected.
When the solenoid valve dead electricity: silently water outlet and relief hole are closed through connecting spring promotion steel under the effect of spool at pressure spring with rubber diaphragm separator.At this moment the water of water-inlet cavity is closed water outlet through pressure compensation opening entering pressure equalizing chamber more reliably.
When solenoid valve was switched on, spool moved up, and opens relief hole, and at this moment pressure equalizing chamber and water chamber are communicated with, and the indoor pressure of pressure balance descends rapidly, at this moment under the effect that connects spring force with valve open.
But we find because relief hole and pressure compensation opening are less from practical situations; Therefore the metal granule of trickle sand grains in the feed pressure balance cylinder and powdery mixes and can't discharge; Just be deposited on that this is indoor cumulative, cause spool blocked, thereby cause that the valve open and close are malfunctioning; Cause the cooling liquid can't normal supply, caused the origin cause of formation of dry abrasive cutting.
In order to address the above problem; Though exist in the existing technology through setting up poker, setting up measure such as anti-blocking baffle plate and prevent to stop up the cooling liquid that causes and do not supply with; But above-mentioned means can't be applicable to the structure of Electromagnetic Control valve; Or can't match with other equipment of grinding with the processing of fluid-link steering machine tooth bar, so this problem can not get solving effectively always.
So press for a kind of novel nonclogging cooling liquid valve at present; Can let fluid-link steering machine tooth bar add man-hour, can not take place because the trickle sand grains and the metal granule of powdery are sneaked into cooling liquid, and cause the problem of valve blockage; Make cooling liquid supply with smoothly, produce and carry out smoothly.
