DETAILED DESCRIPTION

[0018] The application relates to a deformable lubricant nozzle for milling a commercial vehicle wheel hub.

[0019] In the first embodiment of the application, as shown in Figure 1 and Figure 2 The deformable lubricant nozzle for milling a commercial vehicle wheel hub (hereinafter referred to as the application) comprises a wide nozzle deformation assembly 1, a soft nozzle 2, a main nozzle 3, a liquid supply pipe interface 4, a jet nozzle 5, a telescopic control machine 6 and a telescopic rod 6-1. The soft nozzle 2 is fixedly connected to the rear part of the main nozzle 3, and the telescopic control machine 6 is fixedly installed at the rear part of the main nozzle 3. The telescopic control machine 6 controls the telescopic movement of the jet nozzle 5. The main nozzle 3 is provided with two wide nozzle deformation assemblies 1 at equal intervals on the side close to the soft nozzle 2, and the liquid supply pipe interface 4 is connected to the side of the main nozzle 3.

[0020] The application with the application publication number CN103639081A (hereinafter referred to as the patent) can control the flow rate, but cannot change the spraying mode of the milling liquid, and cannot flush the metal scraps on the surface of the workpiece in time, especially the jet nozzle cannot accurately direct the water flow under the interference of the piston part, and the effect is not good in the milling process. The application uses the deformable soft nozzle 2, cooperates with the wide nozzle deformation assembly 1 and the jet nozzle 5 to change the shape and size of the nozzle of the soft nozzle 2, changes the flow rate and spraying form of the milling liquid, effectively adapts to the working state of the milling process, and improves the lubricating, cooling and flushing efficiency.

[0021] The second embodiment is basically the same as the first embodiment, and the difference lies in that, as shown in Figure 3 and Figure 4As shown, the wide nozzle deformation assembly 1 includes a pressure rod 1-1 and a pressure rod control motor 1-4. The pressure rod connecting arm 1-2 is movably mounted on the surface of the main nozzle 3 via a bracket. The front end of the pressure rod connecting arm 1-2 is fixedly connected to the pressure rod 1-1, and the rear end is connected to the control terminal 1-3 via a hinge. The output shaft of the pressure rod control motor 1-4 is screwed to the control terminal 1-3 via a screw. The jet nozzle 5 includes a jet nozzle 5-1 and a control base 5-5. Three or four triangular elastic flaps 5-2 are evenly spaced on the side of the base ring 5-3 facing the soft nozzle 2. The ends of the elastic flaps 5-2 are fixedly connected to the jet nozzles 5-1. When the three or four jet nozzles 5-1 are closed, they form a small nozzle. The other side of the base ring 5-3 is connected to the control base 5-5 via a control connecting rod 5-4. The telescopic rod 6-1 of the telescopic control machine 6 is fixedly connected to the control base 5-5.

[0022] To further optimize the working efficiency of this application and to make the pipeline connection more stable, the liquid supply pipe interface 4 is provided with a milling fluid pipe connection port with a rib ring. To improve the flow directionality of the milling fluid, the soft nozzle 2 is provided with guide fins on the inner side of the nozzle orifice.

[0023] To use, install the deformable nozzle for lubricant suitable for commercial wheel hub milling, then replace the original nozzle and connect the control terminal; the equipment is then ready for use.

[0024] When this utility model is used, its specific operation is as follows:

[0025] In use, if it is needed to flush the cutter head with medium-speed milling liquid, the wide-nozzle deformation assembly 1 and the jet-flow nozzle 5 are in the reset state, and the milling liquid is directly sprayed by the soft nozzle 2; when it is needed to speed up the flow rate of the milling liquid, the motor built in the telescopic control machine 6 drives the tooth belt on the telescopic rod 6-1 to make the telescopic rod 6-1 extend, or the transmission shaft of the motor drives the screw rod to make the telescopic rod 6-1 extend, so that the telescopic rod 6-1 extends to push the control base 5-5, the control connecting rod 5-4 and the base ring 5-3 to push the elastic flap 5-2 to move forward, the elastic flap 5-2 is folded under the converging action of the soft nozzle 2 after moving forward to the soft nozzle 2, and then the jet-flow nozzle 5-1 at the end of the elastic flap 5-2 is folded to form a nozzle with a smaller aperture, the pressure of the spray head is increased, and the spraying force of the milling liquid is increased, wherein, since the soft nozzle 2 is soft, the farther the jet-flow nozzle 5 extends, the greater the pressure received by the jet-flow nozzle 5-1 and the elastic flap 5-2, and the sealing performance can be further improved by the sealing rubber strip at the edges of the jet-flow nozzle 5-1 and the elastic flap 5-2, so that the milling liquid can only be sprayed from the nozzles formed by the folding of the jet-flow nozzle 5-1. When it is needed to flush the debris with the milling liquid in a wider water flow, the screw rod is driven by the pressure-rod control motor 1-4, the control terminal 1-3 is driven up and down by the screw rod, the control terminal 1-3 drives the pressure-rod connecting arm 1-2 to form a seesaw structure, drives the pressure rod 1-1 to be pressed downward, the two pressure rods 1-1 are folded to each other and press the soft nozzle 2 from top to bottom, so that the nozzle of the soft nozzle 2 changes from a circular hole to a waist shape, so that the milling liquid can directly clean the workpiece in a wider spray flow.

[0026] In conclusion, the lubricating liquid deformable nozzle suitable for milling of a commercial vehicle hub can change the flow rate and spraying form of the milling liquid by replacing the original nozzle with the soft nozzle 2, changing the shape and size of the nozzle of the soft nozzle 2 by the wide-nozzle deformation assembly 1 and the jet-flow nozzle 5, so that the milling liquid supply system of the milling equipment can run at a constant power, the spray flow control is only controlled by the nozzle, the milling efficiency can be effectively improved, and the working pressure of the pump and the electric control valve is reduced.
