DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 6 As shown, the utility model provides a speed control device for process gas injection of a coating equipment, comprising a coating box 1, a bracket 21 is arranged inside the coating box 1, a storage box 2 is fixedly installed at the rear end of the coating box 1, an air pump 3 is fixedly installed at the top of the storage box 2, an air pipe 4 is fixedly installed at the output end of the air pump 3, and both ends of the air pipe 4 extend downward to the interior of the storage box 2;

[0025] The gas control mechanism is arranged at the left and right ends of the storage box 2. The gas control mechanism includes an air pipe 5, which is fixedly connected to the left and right ends of the storage box 2. The left and right ends of the coating box 1 are fixedly installed with connecting blocks 6. The opposite sides of the connecting blocks 6 are provided with air inlet holes 7. The other end of the air pipe 5 is fixedly connected to the air inlet hole 7. The top of the connecting block 6 is provided with a slide groove 8. The inside of the slide groove 8 is provided with a baffle 9. The left and right sides of the two connecting blocks 6 are fixedly installed with a fixed shell 10. The internal elastic connection of the fixed shell 10 A spring 11 is connected, and an extrusion rod 12 located inside the fixed shell 10 is fixedly installed on the top of the spring 11. The opposite sides of the top of the extrusion rod 12 are fixedly connected to the two sides of the baffle 9. A square shell 14 is fixedly installed on the top of the baffle 9. A limiting rod 15 is fixedly installed inside the square shell 14. A slider 16 is slidably connected to the surface of the limiting rod 15. Motors 17 are fixedly installed on the left and right ends of the coating box 1, and a push rod 18 is fixedly installed on the output end of the motor 17. The other end of the push rod 18 is hinged to the inside of the slider 16.

[0026] The above scheme is adopted: the operator fixes the workpiece on the surface of the bracket 21, and then the coating box 1 enters a sealed state, and then the air pump 3 can be driven, and then the gas generated by the air pump 3 will enter the interior of the air pipe 1 4, and then the gas inside the air pipe 1 4 will enter the interior of the storage box 2, and then the air pressure inside the storage box 2 will increase, and then the argon and acetylene inside the storage box 2 will enter the interior of the air pipe 2 5 respectively, and then the argon and acetylene inside the air pipe 2 5 will enter the interior of the coating box 1 through the air inlet 7, and then the cathode power supply can be driven, so that the target material inside the device will react with the argon and acetylene, and then a Cr layer and a DLC layer will be formed on the surface of the workpiece, so that the hardness and wear resistance of the workpiece can be increased;

[0027] When the flow rate of the gas needs to be controlled, the motor 17 can be driven to rotate the push rod 18. Since one end of the push rod 18 is hinged to the inside of the slider 16, when the push rod 18 rotates, it will drive the slider 16 to move on the surface of the limit rod 15, and then the push rod 18 will push the limit rod 15 and the square shell 14 down, and then the square shell 14 will drive the baffle 9 to go down, and then the baffle 9 will drive the extrusion rod 12 to go down, and then the extrusion rod 12 will squeeze the spring 11, and then the baffle 9 will block the surface of the air inlet 7, so as to reduce the flow rate of the gas, thereby improving the uniformity and adhesion of the coating;

[0028] When it is necessary to increase the flow of gas, the motor 17 can be driven to make the push rod 18 rotate in the opposite direction, and then the slider 16 will be reset, and then the compressed spring 11 will push the extrusion rod 12 and the baffle 9 to rise, and then the surface of the baffle 9 will move away from the surface of the air inlet 7, and then the flow of gas can be increased.

[0029] like Figure 4As shown, a partition plate 19 is fixedly installed inside the storage box 2, and the partition plate 19 is designed to be square. Pressure gauges 20 are fixedly installed on the left and right ends of the storage box 2, and the pressure gauges 20 are designed to be longitudinally symmetrical about the center of the coating box 1.

[0030] The above scheme is adopted: through the design of the partition plate 19, argon and acetylene can be pumped into the interior of the storage box 2, and then the partition plate 19 will separate the argon and acetylene into two parts, thereby preventing the argon and acetylene from mixing together and affecting the coating of the device; through the design of the pressure gauge 20, when the argon and acetylene are pumped into the interior of the storage box 2, the pressure gauge 20 will display the pressure inside the storage box 2, thereby avoiding excessive pressure and causing damage to the storage box 2.

[0031] like Figure 1 and Figure 3 As shown, an air inlet pipe 23 is fixedly installed on the top of the storage box 2, and a valve 24 is arranged on the surface of the air inlet pipe 23. There are two air inlet pipes 23 and two valves 24. A door panel 13 is arranged at the front end of the coating box 1. The coating box 1 and the door panel 13 are hinged by a hinge chain 22.

[0032] The above scheme is adopted: through the design of the air inlet pipe 23 and the valve 24, argon and acetylene can be injected into the interior of the storage box 2 from the two air inlet pipes 23 respectively. After the injection is completed, the valve 24 can be closed to prevent argon and acetylene from flowing out from the interior of the storage box 2; through the design of the door panel 13 and the hinge chain 22, after the workpiece is fixed, the hinge chain 22 can be rotated to make the coating box 1 enter a sealed state to prevent leakage after the argon and acetylene are stored in the storage box 2.

[0033] like Figure 1 and Figure 5 As shown, there are four fixed shells 10 and springs 11, and each group of two fixed shells 10 and springs 11 is located at the left and right ends of the connecting block 6; the slide groove 8 and the baffle plate 9 are both U-shaped in design, and the surface of the baffle plate 9 contacts the inner wall of the slide groove 8.

[0034] The above scheme is adopted: through the design of the fixed shell 10 and the spring 11, when the baffle 9 is reset, the four springs 11 will simultaneously push the two extrusion rods 12 and the baffle 9 to move, thereby increasing the stability of the movement of the baffle 9; through the design of the slide groove 8 and the baffle 9, since both the slide groove 8 and the baffle 9 are U-shaped designs, the baffle 9 can enter the interior of the slide groove 8, thereby controlling the flow rate of the gas.

[0035] The working principle and use process of this utility model:

[0036] First, the operator can draw argon and acetylene from the air inlet pipe 23 into the storage box 2, and then the partition plate 19 can separate the two gases. After the gas addition is completed, the workpiece can be fixed on the surface of the bracket 21, and then the storage box 2 can enter the sealing device, and then the air pump 3 can be driven to extract the gas, and then the gas will enter the storage box 2 to increase the pressure of the storage box 2, and then the argon and acetylene inside the storage box 2 will enter the inside of the air pipe 25 respectively, and then the gas will enter the inside of the coating box 1, and then the cathode power supply can be driven to make the target react with the argon and acetylene, and then a Cr layer and a DLC layer will be formed on the surface of the workpiece, thereby increasing the hardness and wear resistance of the workpiece;

[0037] When the flow rate of the gas needs to be controlled, the motor 17 can be driven to rotate the push rod 18, and then the push rod 18 will push the slider 16 to move on the surface of the limit rod 15, and then the push rod 18 will push the square shell 14 and the baffle 9 to descend, and the baffle 9 will enter the inside of the slide groove 8, and then the baffle 9 will drive the extrusion rod 12 to descend and squeeze the spring 11, and then the surface of the baffle 9 will block the air inlet 7, which can reduce the flow rate of the gas, thereby improving the uniformity and adhesion of the coating;

[0038] When the gas flow rate needs to be restored, the motor 17 can be driven to make the push rod 18 rotate in the opposite direction, and then the compressed spring 11 will push the extrusion rod 12 and the baffle 9 to rise, and then the baffle 9 will move away from the surface of the air inlet 7, and then the device will restore the gas flow rate, and finally complete the operation process.
