Description

Technical Field

[0001] The present invention relates to the technical field of valve body processing, and specifically to an efficient valve body processing method. Background Art

[0002] The valve body is a main component in a valve; there are different mechanical manufacturing methods according to the pressure grade. The definition of a "valve" is a device used to control the direction, pressure, and flow rate of a fluid in a fluid system. A valve is a device that enables the medium (liquid, gas, powder) in a piping and equipment to flow or stop and can control its flow rate. However, in the prior art, the valve body is prepared by casting or machining. Due to potential factors such as processing flow design, reference coordination and conversion, and cutting amount distribution, the product is prone to deformation, and the out-of-tolerance rate of the form and position tolerances of the valve body is relatively high. Therefore, the product dimensions are also unstable, and finally the production efficiency of the valve body is very low. In view of this, we propose an efficient valve body processing method. Summary of the Invention

[0003] To make up for the above deficiencies, the present invention provides an efficient valve body processing method.

[0004] The technical solution of the present invention is as follows:

[0005] An efficient valve body processing method includes the following steps:

[0006] Step 1: Obtain a valve body blank through 3D printing, and sequentially place the valve body blanks in batches into a processing box for processing;

[0007] Step 2: Set a fixture structure in the processing box, perform a first clamping on the valve body blank, and then sequentially mill both sides of the valve body blank through a processing power structure, and process through holes and flange connection holes;

[0008] Step 3: When rotating the fixture structure to reverse the valve body blank, replace the processing tool on the processing power structure, and then sequentially process through holes on the upper and lower end faces of the valve body blank to obtain the valve body of an efficient reversing valve;

[0009] Step 4: When performing the first clamping and reversing, a light source lamp with horizontal light passing through the through hole of the valve body blank is provided in the processing box. The horizontal light emitted by the light source lamp passes through and is located at the axis of the through hole of the valve body blank, and an inductor for receiving the horizontal light emitted by the light source lamp is provided in the processing box. An alarm for receiving light is provided on the inductor to perform reference positioning on the processing of the valve body blank.

[0010] Further, observation windows one and two are respectively provided on both sides of the processing box, and two symmetrical push plates are slidably installed in the middle of the bottom of the processing box. A pusher is fixedly provided on each push plate.

[0011] Further, a movable door is slidably installed in the middle above the processing box body. A handle is fixedly installed on the movable door, and the movable door is transparent.

[0012] Further, the light source lamps are all installed on the first observation window, and the sensors are all installed on the second observation window.

[0013] Further, the fixture structure includes:

[0014] Two connecting pieces. A first power source for driving the rotation of the two connecting pieces is arranged on the outer sides of the two connecting pieces. Three fixture pieces are fixedly connected between the two connecting pieces, and a valve body blank is clamped on each fixture piece.

[0015] Further, the processing power structure includes:

[0016] Two moving plates. Guide members are arranged at the upper ends of the two moving plates. A second power source for driving the movement of each moving plate is arranged at the lower end of each moving plate, and the lower end of each moving plate is slidably installed at the bottom end inside the processing box body.

[0017] Further, a circulating component is arranged on each moving plate, and a single-thread power head, multiple thread power heads and milling cutter heads which are symmetrically arranged up and down are slidably arranged on the circulating component.

[0018] Further, a first slider is fixedly connected to the rear end of the single-thread power head, and a connecting plate is fixedly sleeved at the power head at the front end of the single-thread power head. First sliding rods are slidably sleeved on both sides of the connecting plate.

[0019] Further, a second slider is fixedly connected to the rear end of the multiple thread power heads. The area of the second slider is larger than that of the first slider. Three second sliding rods are slidably sleeved at the multi-cutter head at the front end of the multiple thread power heads.

[0020] Further, a third slider is fixedly connected to the rear end of the milling cutter head. The area of the third slider is the same as that of the first slider.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. By setting the light source lamp, the sensor and the alarm, during the first clamping and commutation of the valve body, the horizontal light rays emitted by the light source lamp penetrate and are located at the axis of the through hole of the valve body blank.

Finally, the valve body of the high-efficiency reversing valve is obtained, ensuring the accuracy of valve body production. BRIEF DESCRIPTION OF THE DRAWINGS

Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention

[0041] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention

[0042] Please refer to Figure 1-10 the following embodiments of the present invention will be used to elaborate the above technical solutions

[0043] An efficient valve body processing method is realized through the cooperation of the following equipment and steps

[0044] The processing box 1 is provided with an observation window one 11 and an observation window two 12 on both sides respectively. Two symmetrical push plates 13 are slidably installed in the middle of the bottom of the processing box 1, and a pusher is fixedly arranged on each push plate 13. The light source lamps 111 are all installed on the observation window one 11, and the sensors 121 are all installed on the observation window two 12

[0045] By setting the first observation window 11 and the second observation window 12, workers can observe the machining situation of the valve body at any time to ensure the normal progress of the entire machining process. A light source lamp 111 is set, and the horizontal light emitted by it passes through and is located at the axis of the through hole of the valve body blank 34. Then, the light emitted by the light source lamp 111 is received by the sensor 121. At the same time, in cooperation with the alarm on the sensor 121, if the light is not received or is offset, the alarm can give an alarm reminder, thereby ensuring the axial positioning when machining the through hole of the valve body, avoiding the deviation of the axis of the through hole, and improving the machining quality of the valve body. By setting the push plate 13, the waste generated in the machining box 1 can be discharged from the bottom, which is convenient for centralized treatment.

[0046] Moving door 2, a moving door 2 is slidably installed in the middle above the machining box 1. A handle is fixedly installed on the moving door 2, and the moving door 2 is transparent.

[0047] By setting the open moving door 2, the valve body can be freely placed into the machining box 1 for machining. At the same time, it can also ensure that the entire machining box 1 is in a closed state during machining to avoid accidental injury.

[0048] Fixture structure 3, the fixture structure 3 includes: two connecting pieces 32. On the outer sides of the two connecting pieces 32, a first power source for driving their rotation is provided. Three sets of fixture parts 33 are fixedly connected between the two connecting pieces 32, and a valve body blank 34 is clamped on each fixture part 33.

[0049] In this embodiment, it should be supplemented that both of the two connecting pieces 32 are composed of a U-shaped frame and a connecting shaft. The two connecting shafts are rotatably installed on the side wall of the machining box 1. The two first power sources are both rotary motors 31. One end of each of the two connecting shafts is fixedly connected to the rotary motor 31, and the two rotary motors 31 are both installed inside the side wall of the machining box 1;

[0050] It should also be supplemented that the three fixture parts 33 are fixedly connected to each other. Each fixture part 33 includes: two symmetric U-shaped seats 331. A resisting seat 332 is installed on each of the two U-shaped seats 331. A clamping seat 333 is rotatably installed on one side of the upper end of each U-shaped seat 331, and the other side is connected to the clamping seat 333 by a screw. The inner side of each resisting seat 332 is trapezoidal, and an anti-wear pad is fixedly installed on the inner side of each resisting seat 332. The anti-wear pad is engaged with the lower end of the valve body. The lower end of each clamping seat 333 is in a semi-circular shape, and the arc-shaped part of the clamping seat 333 is engaged with the upper end of the valve body.

[0051] First, obtain the valve body blank 34 through 3D printing. The amount left for machining is small, the material removal amount is also small, which saves costs and has little deformation. Then, manually place each valve body blank 34 on the corresponding low-grade seat 332, and then manually tighten the screws. Press the clamping seat 333 against the upper part of each valve body blank 34. Thus, each valve body blank 34 is clamped on each fixture part 33, ensuring the stability during the machining process of the valve body blank 34. Thereby, the valve body blanks 34 can also be grouped into three for batch machining, reducing the machining deformation of the product and improving the machining efficiency. After the two sides of the valve body blank 34 are machined, start the rotary motors 31 on both sides to drive the two connecting shafts to rotate. Then, the two connecting shafts drive the two U-shaped frames and the fixture parts 33 to rotate together. Thus, the upper and lower end faces of the valve body clamped on the fixture part 33 can be rotated to the horizontal state for further machining. Thereby, the number of clamping times can be reduced, the machining speed can be increased, and the labor intensity of the staff can be reduced at the same time.

[0052] The machining power structure 4 includes: two moving plates 41. Guide members are provided at the upper ends of the two moving plates 41. A second power source for driving the movement of each moving plate 41 is provided at the lower end of each moving plate 41, and the lower end of each moving plate 41 is slidably mounted on the inner bottom end of the machining box body 1. A circulating member 44 is provided on each moving plate 41. A single threaded power head 45, a plurality of threaded power heads 46, and a milling cutter head 47 which are symmetrically arranged up and down are slidably provided on the circulating member 44. A slider one 451 is fixedly connected to the rear end of the single threaded power head 45, and a connecting plate 452 is fixedly sleeved at the power head at the front end of the single threaded power head 45. Slide rods one 453 are slidably sleeved on both sides of the connecting plate 452. A slider two 461 is fixedly connected to the rear end of the plurality of threaded power heads 46. The area of the slider two 461 is larger than the area of the slider one 451. Three slide rods two 462 are slidably sleeved at the multi-cutter head at the front end of the plurality of threaded power heads 46. A slider three is fixedly connected to the rear end of the milling cutter head 47, and the area of the slider three is the same as the area of the slider one 451.

[0053] In this embodiment, it is worth supplementing that the guide member is composed of two guide rods 42. The two guide rods 42 are slidably connected to the two moving plates 41, and both ends of the two guide rods 42 are fixedly installed at the upper ends of the side walls of the machining box body 1. Each second power source is an electric cylinder 43. The piston rod of each electric cylinder 43 is fixedly connected to the lower end of each moving plate 41, and each electric cylinder 43 is installed inside the bottom of the machining box body 1.

[0054] It is also worth supplementing that the circulating component 44 includes: two transmission wheels 443, on each of the two transmission wheels 443, a rotating shaft is fixedly connected, the rotating shafts are all rotatably installed on the moving plate 41, and one of the transmission wheels 443 is fixedly connected with a stepping motor 441 through the rotating shaft, the stepping motor 441 is fixedly installed on the moving plate 41, and a transmission chain 442 is rotatably connected between the two transmission wheels 443, the transmission chain 442 is fixedly connected with each slider one 451, each slider two 461 and each slider three, guide blocks 444 are arranged at both the upper and lower ends of the transmission chain 442, both of the two guide blocks 444 are installed on the moving plate 41, and the guide blocks 444 are slidably connected with the slider one 451, the slider two 461 and the slider three.

[0055] After clamping a group of valve body blanks 34, then start the electric cylinder 43 to push the two moving plates 41. Under the action of the two guide rods 42, the two moving plates 41 can stably approach both sides of the clamped valve body blank 34, so that the single-thread power head 45, the multiple-thread power heads 46 and the milling cutter head 47 approach both sides of the valve body blank 34, facilitating the machining of both sides of the valve body blank 34; then start the stepping motor 441, control the speed variable of its rotation, and control the entire machining power structure 4 to pause for machining three times. Furthermore, the stepping motor 441 drives the rotating shaft fixedly connected to it to rotate. Since the rotating shaft is fixedly connected with the transmission wheel 443 and the two transmission wheels 443 are rotatably connected through the transmission chain 442, and since the transmission chain 442 is fixedly connected with each slider one 451, each slider two 461 and each slider three, the single-thread power head 45, the multiple-thread power heads 46 and the milling cutter head 47 that are symmetrically arranged up and down can pause for machining three times, and can move stably and cyclically under the action of the guide blocks 444, so as to perform preliminary machining on both sides of the valve body; however, for the upper and lower two end faces of the valve body, when rotated to the horizontal state, manually replace the power head of the single-thread power head 45 with the power head for machining the end face, and then repeat the above operation to perform fine machining on the upper and lower two end faces of the valve body, thereby obtaining the valve body of the high-efficiency reversing valve and ensuring the accuracy of valve body production.

[0056] During specific use, first obtain the valve body blank 34 through 3D printing, with less material left for machining, less material removal, cost savings, and small deformation; then manually place each valve body blank 34 on the corresponding low-resistance seat 332, and then manually tighten the screws to make the clamping seat 333 press against the upper part of each valve body blank 34. Furthermore, each valve body blank 34 is clamped on each fixture 33, ensuring the stability of the valve body blank 34 during the machining process, and thus it is also possible to group the valve body blanks 34 into three as a group for batch machining, reducing the product machining deformation and improving the product machining efficiency;

[0057] After clamping a group of valve body blanks 34, then start the electric cylinder 43 to push the two moving plates 41. Under the action of the two guide rods 42, the two moving plates 41 can stably approach both sides of the clamped valve body blank 34, so that the single-thread power head 45, the multiple-thread power heads 46 and the milling cutter head 47 approach both sides of the valve body blank 34, facilitating the machining of both sides of the valve body blank 34;

[0058] Then start the stepping motor 441, control the speed variable of its rotation, and control the entire machining power structure 4 to pause the machining three times. Then the stepping motor 441 drives the rotation of the rotating shaft fixedly connected to it. Since the rotating shaft and the transmission wheel 443 are fixedly connected, and the two transmission wheels 443 are rotationally connected by the transmission chain 442. Also, since the transmission chain 442 is fixedly connected to each slider one 451, each slider two 461 and each slider three, the single-thread power head 45, the multiple-thread power heads 46 and the milling cutter head 47 that are symmetrically arranged up and down can pause the machining three times and can move stably and cyclically under the action of the guide block 444, so as to perform preliminary machining on both sides of the valve body;

[0059] Then start the rotary motors 31 on both sides to drive the rotation of the two connecting shafts. Then the two connecting shafts drive the two U-shaped frames and the fixture parts 33 to rotate together, so that the upper and lower end faces of the valve body clamped on the fixture parts 33 can be rotated to the horizontal state. Synchronously, manually replace the power head of the single-thread power head 45 by hand, replace it with the power head for machining the end face, and then repeat the above machining operation to perform fine machining on the upper and lower end faces of the valve body, so as to obtain the valve body of the high-efficiency reversing valve, ensuring the accuracy of valve body production, improving the production efficiency of the valve body, and at the same time reducing the labor intensity of the staff;

[0060] During the machining process, by setting the light source lamp 111, the horizontal light emitted by it penetrates and is located at the axis of the through hole of the valve body blank 34. Then, the light emitted by the light source lamp 111 is received by the sensor 121. At the same time, in cooperation with the alarm on the sensor 121, if the light is not received or is offset, the alarm can give an alarm reminder, so as to ensure the axial positioning when machining the through hole of the valve body, avoid the deviation of the axis of the through hole, and improve the machining quality of the valve body; At the same time, by setting the moving door 2, the observation window one 11 and the observation window two 12, the operator can observe the machining situation of the valve body at any time to ensure the normal progress of the entire machining process;

[0061] Finally, by pushing open the push plate 13, the waste generated in the machining box body 1 can be discharged from the bottom, which is convenient for centralized treatment.

[0062] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present invention, and are not used to limit the present invention.
