Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of numerical control machining, in particular to a pneumatic turbocharged deburring water gun. Background Art
[0002] In the complex multi-process CNC machining process, especially in the processing of deep and fine holes with cross-processing, there are more or less fine burrs in the cross holes. These burrs are difficult to remove, and if they are not removed, the quality of the parts will be seriously affected. Even after the main machine is assembled and run, the burrs will cause quality accidents, so they must be removed.
[0003] The current practice is to purchase a high-pressure deburring machine, which is a CNC machining center dedicated to deburring, and remove the burrs from the parts together. However, this approach is equivalent to adding a separate CNC machining process, which requires additional equipment, customized tools and fixtures, and the arrangement of dedicated personnel for transportation, operation and maintenance, which greatly increases production costs.

[0016] Figure 2 It is the internal structure diagram of the utility model. DETAILED DESCRIPTION
[0017] The technical solution of the present utility model will be further described below with reference to the accompanying drawings and embodiments.
[0018] Figure 1 and 2 The pneumatic turbocharged deburring water gun shown comprises a gun body 1 , wherein the gun body 1 is formed by two symmetrical gun body split structures connected by sealing bolts.
[0019] The gun body 1 is provided with a water cavity 2 and an air cavity 3 which are independent of each other and extend out of the gun body 1 at both ends.
[0020] One end of the water chamber 2 is connected to the water inlet pipe 4, and the other end is connected to the water outlet head 5. The water outlet head 5 is a high-pressure water outlet head. A water chamber turbine bearing bracket 6 is provided inside the water chamber 2, and a water chamber booster turbine 7 is connected.
[0021] One end of the air cavity 3 is connected to the air intake pipe 8, and the other end extends out of the gun body 1. The air cavity 3 is provided with an air cavity turbine bearing bracket 9 and is connected to an air cavity supercharged turbine 10. The water cavity supercharged turbine 7 is connected to the air cavity supercharged turbine 10 through a reduction gear set 11 to increase the torque.
[0022] An air chamber trigger piston 12 is provided in the air chamber 3. One end of the air chamber trigger piston 12 extends from the side wall of the air chamber 3 and is connected to a trigger 13. A spring 14 is provided between the trigger 13 and the gun body 1 in the extended position. When the spring 14 is expanded, the air chamber trigger piston 12 realizes air sealing in the air chamber 3. After the trigger 13 is pressed, the spring is compressed, and the air chamber trigger piston 12 moves and unseals the air chamber 3. After the air enters the air chamber 3, it drives the air chamber supercharger turbine 10 to rotate, and drives the water chamber supercharger turbine 7 to rotate through the reduction gear set 11. The reduction gear set 11 increases the torque to twice the original by the gear ratio of 12 / 24, driving the water chamber boost turbine 7 to rotate at low speed and high torque to draw water from the water inlet pipe 4 and discharge it through the water gun head 5. Since the conventional air pressure at the machine tool air inlet is 0.6MPa, the discharged water flow can be pressurized to 1.2MPa, about 12 kg / cm2, through the reduction gear set 11, and the water outlet diameter is only 2 mm. Theoretically, the water flow pressure at the outlet can reach more than 30 kg, which can completely remove small burrs.
[0023] The water chamber 2 and the air chamber 3 both enter from one side of the gun body 1 and exit from the other side. The water chamber 2 is located at the upper part of the gun body 1, and the air chamber 3 extends from the upper part to the lower part of the gun body 1. The middle part of the gun body 1 is hollowed out to form a hand-holding area. The air chamber trigger piston 12 extends from the air chamber 3 to the hand-holding area. The gun body 1 is provided with a trigger piston plug 15 at the other end of the air chamber trigger piston 12 opposite to the trigger 13. When the trigger 13 is pressed, the trigger piston plug 15 is limited.
[0024] An air intake valve piston 16 is further provided in the air cavity 3 . The air intake valve piston 16 extends out of the gun body 1 and is closed by an air intake valve plug 17 . An air intake regulating valve 18 and an air intake valve locking nut 19 are provided at the extended end.
[0025] The air cavity 3 is connected to the exhaust port silencer 20 through the gun body 1 .
