Description

Technical Field

[0001] The invention relates to a jet processing device. Background Art

[0002] Jet processing is a special processing technology. Its equipment uses the principle of liquid supercharging. Through a specific device (supercharging port or high-pressure pump), the mechanical energy of the power source is converted into pressure energy. The water with huge pressure energy passes through the small hole nozzle, and then the pressure energy is converted into kinetic energy, thus forming a high-speed and high-energy jet. Due to the advantages of high precision, high power, miniaturization and low requirements for part shape, jet processing is widely used in the cutting, perforation and surface material removal of materials in important fields such as machinery manufacturing, aerospace and military equipment. With the continuous development of modern manufacturing industry, the demand for jet processing equipment in specific mechanical processing fields is constantly refined, and its role is becoming more and more important. Therefore, the quality of material processing in the jet process greatly affects the overall quality of many industrial and agricultural products.

[0041] like Figure 5 As shown, the turntable 14 of the present invention is provided with a speed change slot 16, and the stirring grid 12 is fixed on the speed change slot 16 by a fixing pin 15. The stirring grid is fixed on the turntable by a hinged rotating rod and a fixing pin, and moves with the turntable.

In addition, a laser distance measuring device is provided on the outside of the nozzle to measure the distance from the nozzle to the surface of the sample, which is conducive to the knife setting operation of the sample.

[0046] The present invention also includes a numerical control device 28 which is electrically connected to the motion device 100 , the acceleration device 8 and the stirring device 101 .

[0047] The working principle of the present invention is as follows:

[0048] The present invention can realize different forms of jet processing, such as uniform jet processing and deterministic jet processing. The working process of uniform jet processing is as follows: first, the sample is installed on the sample table, and the sample surface is leveled by the laser distance measuring device on the nozzle. The protective cover is installed, and then the shape and size of the nozzle are adjusted, and the angle of the nozzle pipeline is adjusted by the electromagnetic steering device, especially the workpiece with a free-form surface. The working liquid is poured into the stirring tank, the turntable is started, and the stirring grid is driven to stir the working liquid uniformly. After stirring, the cylinder is started, the corresponding heating / cooling or normal temperature switch outlet is opened, and the working liquid is sucked into the first-stage acceleration pump. When the cylinder moves to the right, the piston of the first-stage acceleration pump compresses the sucked liquid to enter the acceleration pipeline. At this time, the piston in the second-stage acceleration pump moves to the right under the drive of the connecting rod, and the air pressure is reduced, and the working liquid of the acceleration pipeline is sucked into the second-stage acceleration pump. When the cylinder moves to the right, the piston of the second-stage acceleration pump is driven to compress the working liquid so that it comes out from the acceleration outlet. Then enter the nozzle pipeline and prepare for processing. Set the rotation speed of the sample table, and then start processing.

[0049] The working process of deterministic jet machining is as follows: first, the sample is mounted on the sample table, and the sample surface is leveled by the laser distance measuring device on the nozzle. Then, various parameters of machining are determined, namely, machining speed, machining temperature, working liquid type, machining angle, etc. (known to those skilled in the art). After the parameters are determined, the removal efficiency is measured. After the removal efficiency of the given parameters per unit time is measured, the CNC code of deterministic machining is obtained in combination with the surface morphology of the sample surface, and poured into the CNC system. Then, the shape and size of the nozzle are adjusted, and the angle of the nozzle pipeline is adjusted by the electromagnetic steering device, especially for workpieces with free-form surfaces. Pour the working liquid into the mixing tank, start the turntable, and drive the mixing grid to stir the working liquid evenly. After stirring, start the cylinder, open the corresponding switch outlet for heating / cooling or normal temperature use, and suck the working liquid into the first-stage accelerator. When the cylinder moves to the right, the piston of the first-stage acceleration pump compresses the sucked liquid to enter the acceleration pipeline. At this time, the piston in the second-stage acceleration pump moves to the right driven by the connecting rod, and the air pressure is reduced, and the working liquid of the acceleration pipeline is sucked into the second-stage acceleration pump. When the cylinder moves to the right, it drives the piston of the secondary accelerator pump to compress the working fluid and make it come out from the accelerator outlet. Then it enters the nozzle pipe and starts to prepare for processing. Set the rotation speed of the sample table, read the CNC code, and control the machine tool to start processing.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
