Description
Technical field:
The utility model belongs to the compression casting equipment technical field, relates in particular to a kind of injection travel displacement control device.
Background technology:
The development history of compression casting technology is exactly the logical process of the understanding that deepens continuously of each technological parameter of die casting being studied and each technological parameter is updated control.In traditional die casting control procedure, generally adopt travel switch or rotary encoder to come the injection travel displacement is controlled; No matter but be travel switch or rotary encoder, in injection travel displacement control procedure, all there is certain defective in various degree.Travel switch is lower to the control positioning accuracy of displacement point, the scope fluctuation is bigger, generally about ± 3mm, and the composite entity structure of travel switch and other part of die casting machine is too disperseed, be not easy to regulate, multistage if necessary injection control also has travel switch and interferes with each other and cause detecting and the drawback of output signal.Thereby can produce mechanical contact wear during rotary encoder work or beat and influence the transmission of the instability of accuracy of detection and detection signal; The composite entity structure of rotary encoder and other parts of die casting machine is too complicated and contact stress and contact wear arranged; In addition, in the injection process, die casting machine unavoidably has certain vibrations, and the rotary encoder shock resistance is poor, adds that the adverse circumstances in the actual production are polluted, thereby the easy fracture of the numeration dish of rotary encoder causes operational failure.
The utility model content:
The purpose of this utility model is intended to overcome the deficiencies in the prior art, provides a kind of simple in structure, can carry out the injection travel displacement control device of precise displacement control to the injection stroke in the die casting machine injection process.
The utility model is mainly realized goal of the invention by following technical solution:
A kind of injection travel displacement control device, it comprises bearing, is located at the limit switch bar on the bearing, be fixed at the magnetic railings ruler on the limit switch bar, be sheathed on the inductance loop on the limit switch bar, be located at the location-plate on the bearing, and be located at encoder and inductive switch on the bearing; Described limit switch bar is connected with piston rod by connecting plate, described location-plate with limit switch bar and piston rod positioned parallel in same horizontal plane.
Have elongated slot on the wherein said limit switch bar, magnetic railings ruler is fixed in the elongated slot.
Wherein said limit switch bar is arranged with protecting tube outward.
Wherein said encoder is provided with a panel beating protective cover outward.
Wherein said bearing also is provided with one lubricated mouthful, and lubricated mouthful is connected with the moving conduit of limit switch bar.
The utility model beneficial effect is: the utility model is simple in structure, and electrical equipment adopts non-contact type magnetic railings ruler and encoder, the position detection accuracy height, and precision can reach 0.1mm; The composite entity of the utility model machine components is simple in structure, compact and reasonable; In addition, because the utility model is adopted contactless induction detection mode, so induction control element shock resistance is strong, long working life.

The specific embodiment:
Below in conjunction with accompanying drawing the technical solution of the utility model is described further:
As shown in Figure 1 and Figure 2, a kind of injection travel displacement control device, it comprises bearing 7, be located at the limit switch bar 1 on the bearing 7, be fixed at the magnetic railings ruler 2 on the limit switch bar 1, in the present embodiment, have the elongated slot (not shown) on the limit switch bar 1, magnetic railings ruler 2 is fixed in the elongated slot, and the utility model is not limited to this fixed installation mode certainly; The main effect of magnetic railings ruler 2 is and is located at the displacement measurement that encoder 3 on the bearing 7 is finished piston rod 12 jointly, when the relevant scale on the magnetic railings ruler 2 passes through encoder 3, encoder 3 can collect related data and send to host computer, thereby can determine to take by force the height switching of power and the speed switching of speed according to the needs of product, to guarantee the quality of die-cast product; In addition, because be that contactless induction comes image data between magnetic railings ruler 2 and the encoder 3, so do not have contact stress and contact wear between them, testing result is accurate.
Be arranged with inductance loop 10 on the limit switch bar 1, it finishes jointly with the inductive switch of being located on the bearing 79 whether piston rod 12 is got back to the detection of injection starting point, inductance loop 10 is fixed on the limit switch bar 1, and inductive switch 9 positions are also fixed, before piston rod 12 injections, inductance loop 10 is corresponding with inductive switch 9 positions; When finishing once or repeatedly after the injection, piston rod 12 returns starting point, limit switch bar 1 will be got back to starting point synchronously, inductance loop 10 is got back to the position corresponding with inductive switch 9 again, inductive switch 9 returns relevant information to computer, thereby computer can send the order of carrying out other action according to this information to die casting machine; Because inductance loop 10 also adopts contactless work with inductive switch 9, also has the advantage that does not have contact wear.
Also be provided with a location-plate 8 on the bearing 7, it mainly acts on is that limit switch bar 1 is positioned, and behind location-plate 8 location, limit switch bar 1 is in the same horizontal plane in parallel to each other with piston rod 12; In addition, limit switch bar 1 is connected with piston rod 12, makes limit switch bar 1 and piston rod 12 keep synchronous shift by connecting plate 6; Only in this way, the displacement of the stroke of limit switch bar 1 could be equivalent with the stroke displacement of piston rod 12, in other words, just can obtain the travel displacement of piston rod 12 by the travel displacement of detectability bit switch bar 1.
The outer protecting tube 4 that is arranged with of limit switch bar 1, it mainly acts on and is limit switch bar 1 and the magnetic railings ruler 2 that is fixed on the limit switch bar 1 are effectively protected, and avoids because collision etc. are former thereby cause the damage of limit switch bar 1 and magnetic railings ruler 2.
Be provided with a panel beating protective cover 5 outside the encoder 3, mainly play the effect of protection encoder 3, avoid the on-the-spot rugged environment of die casting to pollute encoder 3.
Bearing 7 also is provided with one lubricated mouthful 11, and lubricated mouthful 11 is connected with the moving conduit of limit switch bar 1.The some machine works circulations of every process can be carried out effectively lubricating to limit switch bar 1 by drop into a certain amount of lubricant in lubricated mouthful 11, play the effect of safeguarding limit switch bar 1.
The above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
