Technical Field

[0001] The utility model relates to the field of martensitic gas valves, in particular to a surface flaw detection processing device for martensitic gas valve steel bars. Background Technique

[0002] Martensite is a tissue name of ferrous metal materials, which is a supersaturated solid solution of carbon in α-Fe. Its three-dimensional tissue morphology is usually sheet-like or plate-like, but it usually appears needle-like in metallographic observation (two-dimensional). The crystal structure of martensite is a body-centered tetragonal structure (BCT). This tissue can usually be obtained by accelerating cooling in medium and high carbon steels. High strength and hardness are one of the main characteristics of martensite in steel. At the same time, the gas valve is a component used to control the gas inlet and outlet of the cylinder in the compressor. The lifting height or closing between the valve plate and the valve seat determines the size and tightness of the gas passage.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , where Figure 1 is a schematic structural diagram of a preferred embodiment of the surface flaw detection processing equipment for martensitic valve steel bars provided by the present utility model; Figure 2 is Figure 1 a schematic structural diagram of the positioning component shown; Figure 3 is Figure 1 a schematic structural connection diagram of the first positioning tube and the arc-shaped plate shown; Figure 4 is Figure 1 a schematic structural connection diagram of the moving plate and the second positioning tube shown; Figure 5 is Figure 1 a schematic structural connection diagram of the liquid storage tank and the spraying head shown. A surface flaw detection processing equipment for martensitic valve steel bars includes a detection box 1. The top of the detection box 1 is rotatably connected by a hinge with a transparent cover 2, and the front surface of the detection box 1 is fixedly connected with a liquid storage tank 3;

[0026] A positioning component 4 is arranged on one side of the detection box 1. The positioning component 4 includes a motor 41, a transmission disc 42, a first positioning tube 43 and a second positioning tube 44. A motor 41 is fixedly connected to one side of the detection box 1, the output end of the motor 41 is fixedly connected with a transmission disc 42, a first positioning tube 43 is fixedly connected to one side of the transmission disc 42, and a second positioning tube 44 is fixedly connected to one side of the inner wall of the detection box 1.

[0027] In the specific implementation process, as Figure 2 and Figure 3 shown, a first spring 5 is welded to one side of the inner wall of the first positioning tube 43. The side of the first spring 5 away from the first positioning tube 43 is welded with a clamping plate 6, and the outer side of the clamping plate 6 is slidably connected with the inner wall of the first positioning tube 43.

[0028] A lead screw mechanism 7 is arranged inside the clamping plate 6, and a moving strip 8 is arranged outside the lead screw mechanism 7.

[0029] The front surface of the moving strip 8 is fixedly connected with an arc-shaped plate 9. A soft plate 10 is arranged inside the inner circle of the arc-shaped plate 9, and the number of the moving strips 8 is set to two.

[0030] A groove 11 is opened inside the first positioning tube 43, and a convex block 12 is fixedly connected to the outer side of the clamping plate 6. The number of both the groove 11 and the convex block 12 is set to four.

[0031] It should be noted that when detecting the martensitic valve steel bar, first, the staff adjusts the position of the clamping plate 6 according to the length of the steel bar through the first spring 5. After the position of the clamping plate 6 is adjusted, the lead screw mechanism 7 starts to operate. Under the action of the lead screw mechanism 7, the two moving bars 8 on its outer side can be driven to move in opposite directions, so that the two moving bars 8 can approach or move away from each other. When the moving bar 8 moves, it can drive the arc-shaped plate 9 to move. Then, when the arc-shaped plate 9 moves, it can drive the flexible plate 10 to move, so that the inner circle of the flexible plate 10 is closely attached to the outer side of the martensitic valve steel bar, thereby fixing the martensitic valve steel bar. At the same time, the steel bars of different lengths can be positioned and fixed through the second spring 16 and the moving plate 17. After the steel bar is positioned, the motor 41 starts to work. Then, the motor 41 can drive the steel bar to rotate through the transmission disc 42 and the first positioning tube 43, so that the magnetic suspension liquid can be evenly sprayed on the outer side of the steel bar.

[0032] Reference Figure 2 、 Figure 4 and Figure 5 As shown in

[0033] On both sides of the inner wall of the detection box 1, inclined plates 13 are fixedly connected, and a collection groove 14 is opened inside the detection box 1.

[0034] An exhaust pipe 15 is arranged inside the detection box 1, and one side of the inner wall of the second positioning tube 44 is welded with a second spring 16.

[0035] A liquid replenishing pipe 18 communicates with the inside of the liquid storage tank 3, and a conveying pipe 19 is arranged inside the liquid storage tank 3.

[0036] One end of the conveying pipe 19 away from the liquid storage tank 3 communicates with a connecting pipe 20. A spraying head 21 communicates with the outside of the connecting pipe 20. A fixing frame 22 is fixedly connected to the outside of the connecting pipe 20, and the front surface of the fixing frame 22 is fixedly connected to the inner wall of the detection box 1.

[0037] It should be noted that by pushing the moving plate 17, the second spring 16 can be compressed, so that the steel bars of different lengths can be positioned and fixed. At the same time, when the magnetic suspension liquid is sprayed on the steel bar, part of the magnetic suspension liquid slides through the inclined plate 13 and is then collected by the collection groove 14. Then, the collected magnetic suspension liquid can be uniformly processed through the exhaust pipe 15. At the same time, the magnetic suspension liquid inside the liquid storage tank 3 can enter the inside of the connecting pipe 20 through the conveying pipe 19 and is then sprayed through a plurality of spraying heads 21, so that the outer side of the steel bar can be evenly sprayed, thereby improving the flaw detection operation of the martensitic valve steel bar.

[0038] The working principle of a surface flaw detection processing device for a martensitic valve steel rod provided by the present utility model is as follows:

[0039] When the staff needs to perform flaw detection processing operations on the martensitic valve steel rod through this device, first open the transparent cover 2, and then adjust the positions of the clamping plate 6 and the moving plate 17 according to the length of the steel rod through the first spring 5 and the second spring 16. After the steel rod is placed, the lead screw mechanism 7 starts to work. Under the action of the lead screw mechanism 7, the moving strip 8 can be driven to move, and then the moving strip 8 can drive the arc plate 9 to move. When the arc plate 9 moves, it drives the flexible plate 10 to move, so that the inner circle of the flexible plate 10 is closely attached to the outer side of the steel rod, thereby fixing and positioning the steel rod. After the steel rod is positioned, start the motor 41. Under the action of the motor 41, the first positioning tube 43 can be driven to rotate through the transmission disc 42. When the first positioning tube 43 rotates, the clamping plate 6 can be driven to rotate through the convex block 12, and then the steel rod can be driven to rotate through the flexible plate 10 with a certain friction. At the same time, the magnetic suspension liquid in the liquid storage tank 3 is transported through the delivery pipe 19 and the connecting pipe 20, so that the magnetic suspension liquid can be sprayed through the spray head 21, and the magnetic suspension liquid can be evenly sprayed on the outer side of the steel rod, thereby improving the efficiency of the surface flaw detection processing operation of the steel rod to a certain extent.

[0040] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present utility model.
