[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The following is based on Figures 1-13 This invention describes a digital information chemical tool model for brake valve components provided in an embodiment of the present invention.

[0031] Please see Figure 1 and Figure 2 The digital information chemical tool model of the brake valve includes a training platform 4 and a screwdriver 10. The training platform 4 includes a platform body 41, which is a table-like structure. Support legs 43 are fixed at the four corners of the platform body 41 to support the platform body 41. A storage cabinet 44 is provided on one side of the lower part of the platform body 41, and a drawer 42 is provided on the other side of the lower part of the platform body 41 for storing valve body parts.

[0032] Preferably, the dimensions of the platform 41 are 1300*700mm*50mm.

[0033] Preferably, the support leg 43 is made of square tubing with dimensions of 40*40*1.2 mm.

[0034] The aforementioned screwing machine 10 is located above the training platform 4. The main component of the screwing machine 10 is a motor. A screwing head is assembled at the power output end of the motor. The shape and size of the screwing head are compatible with the assembly bolt. When the screwing machine 10 is working, it can provide torque to the assembly bolt of the valve. That is, when assembling the valve, the screwing machine 10 is used to tighten the assembly bolt, so that the assembly bolt can connect the various parts of the valve.

[0035] Continue to refer to Figure 1 In order to control the torque and rotation angle of the digital screwdriver 10 when it applies torque to the assembly bolt, a human-machine interaction screen 3 is also set up here. The human-machine interaction screen 3 is located above the training platform 4. The torque value and number of rotations of the screwdriver 10 can be input through the human-machine interaction screen 3, so that the screwdriver 10 applies torque to the assembly bolt according to the preset torque value and number of rotations.

[0036] To obtain the final torque value and number of turns of the assembly bolt, the airtightness of the assembled valve is also tested on training platform 4. When the airtightness test result is qualified, it indicates that the tightening machine 10 has applied torque to the assembly bolt. The torque value and number of turns at this time are the final tightening values. For example, if the torque value is initially input as 30 N·m and the number of turns as 5 on the human-machine interface screen 3, the tightening machine 10 will tighten the assembly bolt according to this data. After tightening, the airtightness of the valve is tested. If the airtightness test is unqualified, it needs to be tightened again, and the torque needs to be input again. The torque value is 35 N·m, and the number of turns is 6. The tightening machine 10 uses this data to tighten the assembly bolts again. After tightening, the airtightness of the valve is tested again. If the airtightness test fails, the torque value and the number of turns need to be changed and the bolts are tightened again. When the airtightness test passes, it is considered that the assembly bolts are finally tightened. Finally, the final tightening data is obtained. For example, if the final tightening data is a torque value of 40 N·m and a number of turns of 7, then the same type of brake valve assembly bolts can be tightened using a torque value of 40 N·m and a number of turns of 7.

[0037] Combination Figures 1-3 As shown, the specific method for airtightness testing is as follows: An operating panel 6 is set up on the training platform 4. The operating panel 6 serves as the assembly location for valve components; that is, the valve components are located on the operating panel 6 during valve assembly and when the screwdriver 10 tightens the assembly bolts. For example… Figure 2 In this configuration, the air brake valve 7 is located on the upper surface of the control panel 6. A rubber pad 61 is provided on one side of the upper surface of the control panel 6. The space on the upper surface of the rubber pad 61 serves as the location for testing the air tightness of the valve. That is, when testing the air tightness, the valve is located on the rubber pad 61, and the end of the valve with the air port should be at the bottom so that the air port can be sealed by the rubber pad 61, facilitating subsequent air tightness testing. An inflation head 13 is also provided, which penetrates the control panel 6 and is located in the area where the rubber pad 61 is located. One end of the inflation head 13 is connected to the air pump 14, and the other end of the inflation head 13... Insert the air head 13 into one of the air ports of the valve and use it to inflate the valve. The rubber gasket 61 can seal the other air ports. So when the air head 13 finishes inflating one of the valve ports of the air brake valve 7, the air pressure inside the air brake valve 7 will not change because the other valve ports are sealed by the rubber gasket 61. The air pressure inside the air brake valve 7 can be detected by using the air pressure gauge 11. The air pressure gauge 11 is set on the training table 4 and connected to the air head 13. A pipe fitting (not shown) should be installed between the two. The air pressure gauge 11 is used to detect the air pressure inside the valve.

[0038] Preferably, the air pump 14 is installed inside the storage cabinet 44.

[0039] Combination Figure 4As shown, a toolbox 2 is also provided. The toolbox 2 includes a box body 21. One side of the box body 21 has a flow box 23 arranged vertically. The flow box 23 contains valve components, such as valve sleeves, air plungers, springs, etc., so that the internal components of the valve can be directly taken out from the corresponding flow box 23 when the operator assembles the valve. On the other side of the box body 21, there is a toolbox 22 arranged vertically. The toolbox 22 contains the tools required for valve assembly, such as wrenches and screwdrivers. These tools are used to remove the assembly bolts after the sealing is found to be insufficient, so as to facilitate changing to a new set of tightening data and retightening with the tightening machine 10. These tools are also used to assemble the various components of the flow box 23.

[0040] The aforementioned process box 23 includes a relay valve process box, a shut-off valve process box, an air brake valve process box, a JZ-7 self-operated valve process box, a JZ-7 single valve process box, a secondary valve process box, a main valve process box, and an emergency vent valve process box; the tool box 22 includes a relay valve tool box, a shut-off valve tool box, an air brake valve tool box, a JZ-7 self-operated valve tool box, a JZ-7 single valve tool box, a secondary valve tool box, a main valve tool box, and an emergency vent valve tool box.

[0041] Preferably, a handle 24 is provided on the upper side of the box 21, and a walking wheel 25 is installed on the lower part of the box 21.

[0042] In actual operation, to facilitate multi-directional operation of the screwdriver 10, a horizontal movement component 5 is also provided, combined with... Figure 1 and Figure 2 The horizontal moving component 5 is installed on the training platform 4. The horizontal moving component 5 includes a column 51, an X-axis guide rod 52, an X-axis sliding block 53, and a Y-axis sliding plate 54.

[0043] There are two columns 51, which are distributed on both sides of the upper surface of the platform 41. The X-axis guide rod 52 is fixed between the upper ends of the two columns 51. The X-axis sliding block 53 is slidably disposed on the X-axis guide rod 52. The Y-axis slide plate 54 is disposed below the X-axis sliding block 53 and can slide along the Y-axis on the X-axis sliding block 53. The Y-axis slide plate 54 serves as the power output end of the horizontal moving component 5. That is, when the X-axis sliding block 53 slides on the X-axis guide rod 52, the Y-axis slide plate 54 slides along the X-axis guide rod 52. The Y-axis slide plate 54 can also slide along the Y-axis on the X-axis sliding block 53, so that the screwing machine 10 below it can move on both the X-axis and the Y-axis.

[0044] Preferably, a T-shaped groove is provided on the upper surface of the Y-axis sliding plate 54, and a T-shaped slider that matches the T-shaped groove is provided on the lower surface of the X-axis sliding block 53.

[0045] Combination Figure 1 , Figure 2 and Figure 5As shown, in order to realize the vertical movement of the screwdriver 10, a Z-axis moving assembly 8 is also provided. The Z-axis moving assembly 8 includes a cylinder 81, a telescopic rod 82 located at the lower end of the piston rod of the cylinder 81, and a fixed plate 83 installed at the lower end of the telescopic rod 82. The cylinder 81 is installed on the upper surface of the Y-axis slide plate 54, and the screwdriver 10 is installed below the fixed plate 83. When the cylinder 81 extends, the telescopic rod 82 can move downward, thereby driving the fixed plate 83 to move downward. Conversely, when the cylinder 81 shortens, the fixed plate 83 can rise, which is used to change the vertical position of the screwdriver 10 so as to tighten the assembly bolts of the valve at different heights.

[0046] Preferably, a rotating disk 84 is rotatably mounted below the fixed disk 83. The rotating disk 84 can rotate about the center of the fixed disk 83. Pins are provided on both sides of the screwdriver 10. The screwdriver 10 is rotatably mounted on the rotating disk 84 through the pins, so that the screwdriver 10 can be operated at multiple angles.

[0047] In practice, it was found that relying solely on the weight of the valve itself to press the air port onto the rubber gasket 61 during the air tightness test resulted in poor sealing. Therefore, a pressure-down component 12 was incorporated here, combined with... Figures 5-8 As shown, the pressing component 12 is axially mounted on the fixed plate 83. When the pressing component 12 moves downward, it can apply pressure to the valve, thereby pressing the air port of the valve onto the rubber pad 61 more tightly, and further sealing the air port of the valve under pressure.

[0048] Specifically, the pressing assembly 12 here includes a top ring 122, which is located above the fixed plate 83. A threaded cylinder 121 is rotatably installed at the lower edge of the top ring 122. The outer surface of the threaded cylinder 121 has external threads and the inner surface has internal threads. The fixed plate 83 is provided with a ball nut 831 that is adapted to the external threads. A threaded rod 124 is connected to the internal threads. A lower ring 123 is fixed at the lower end of the threaded rod 124 and is located below the fixed plate 83. The lower ring 123 is used to press against the upper surface of the valve.

[0049] In this embodiment, when the top ring 122 moves downward, each of the threaded cylinders 121 below also moves downward. When the threaded cylinder 121 passes the ball nut 831, the threaded cylinder 121 will rotate. When the threaded cylinder 121 rotates, its internal thread can generate thread force with the threaded rod 124. Since the threaded rod 124 is restricted by the lower ring 123 below, it cannot rotate but can only move downward. Therefore, compared with the downward displacement of the threaded cylinder 121, the threaded rod 124 will also generate an additional downward displacement, thereby pressing the lower ring 123 against the upper surface of the valve.

[0050] Reference Figure 5 and Figure 9As shown, in order to enable the top ring 122 to move downwards, a return component 9 is also provided. The return component 9 is located above the pressing component 12 and is assembled on the Y-axis slide plate 54. The cylinder 81 drives the screwdriver 10 to the highest position of the valve component. Figure 11 and Figure 12 The state shown) and the least significant bit ( Figure 10 When the area between the states shown moves up and down, the return component 9 does not move, and the cylinder 81 drives the screwdriver 10 to move upwards beyond the highest position of the valve (as shown). Figure 13 (As shown) The return component 9 can push the pressing component 12, causing the pressing component 12 to press down on the valve, forming a state where the valve is pressed against the rubber pad 61, so that the air port of the valve is sealed by pressure.

[0051] In this embodiment, the return component 9 relies on the action of the cylinder 81 to press down the valve of the pressing component 12, without the need for an additional power structure.

[0052] Combination Figure 5 and Figure 9 As shown, the aforementioned return component 9 includes a support platform 95, a drive gear 92, an acceleration gear 93, and a gear plate 91.

[0053] The support platform 95 is suspended on the Y-axis slide plate 54 of the horizontal moving assembly 5. The support platform 95 has a cavity in the middle. The upper end of the telescopic rod 82 passes through the cavity and is fixedly connected to the piston rod of the cylinder 81. The drive gear 92 is rotatably assembled on both sides inside the cavity. Toothed plates 96 are provided on both sides of the telescopic rod 82 near the lower part. When the cylinder 81 drives the screwdriver 10 to move upward to above the highest position of the valve, the toothed plates 96 can mesh with the drive gear 92 (e.g., Figure 12 Thus, when cylinder 81 continues to shorten, gear plate 2 96 can drive the drive gear 92 to rotate; acceleration gear 93 meshes with the side of drive gear 92 away from telescopic rod 82, and a driven gear 94 coaxial with acceleration gear 93 is also provided in the cavity. Drive gear 92 can drive acceleration gear 93 to rotate, and the speed of acceleration gear 93 is greater than that of drive gear 92. Therefore, the speed of driven gear 94 is greater than that of drive gear 92. Gear plate 1 91 is axially slidably mounted on support platform 95, and gear plate 1 91 and driven gear 94 are... The driven gear 94 rotates, which drives the toothed plate 91 to move downward, thereby accelerating the downward push of the pressing component 12. It should be noted that since the rotational speed of the driven gear 94 is greater than that of the driving gear 92, the downward movement speed of the toothed plate 91 is greater than the upward movement speed of the telescopic rod 82. This ensures that when the telescopic rod 82 moves upward a small distance, the pressing component 12 can move downward a large distance. In addition, the extra displacement of the threaded rod 124 ensures that the lower ring 123 can be pressed tightly against the valve.

[0054] Preferably, a tool mesh plate 1 is installed behind the upper surface of the platform 41 for hanging valve components and operating tools.

[0055] The working principle and usage process of this utility model are as follows: First, place the valve components on the operating panel 6, and also place the corresponding components from the process box 23 on the operating panel 6. Then begin assembly. Before assembly, input the torque value and rotation number of 5 turns of the tightening machine 10 onto the human-machine interface screen 3. The operator moves the tightening machine 10 to the required position and uses it to tighten the bolts according to the preset values ​​until the valve is fully assembled. At this point, transfer the valve to the upper surface of the rubber pad 61, with the side of the valve with the air port facing down. Insert the inflation head 13 into one of the air ports and move the tightening machine... Above the rubber pad 61, the cylinder 81 is shortened by controlling the telescopic rod 82, which drives the fixed plate 83 to move upward until it exceeds the highest threshold of the valve. At this time, the toothed plate 96 can mesh with the driving gear 92. When the cylinder 81 continues to shorten, the toothed plate 96 can drive the driving gear 92 to rotate. The driving gear 92 can drive the acceleration gear 93 to rotate, and the speed of the acceleration gear 93 is greater than that of the driving gear 92. Therefore, the speed of the driven gear 94 is greater than that of the driving gear 92. When the driven gear 94 rotates, it can drive the toothed plate 91 to move downward. Since the speed of the driven gear 94 is... The downward movement speed of the toothed plate 91 is greater than that of the drive gear 92, so the downward movement speed of the toothed plate 91 is greater than that of the telescopic rod 82. The downward movement of the toothed plate 91 pushes the top ring 122 downwards, and the various threaded cylinders 121 below also move downwards. When the threaded cylinder 121 passes the ball nut 831, it will rotate. During this rotation, the internal thread of the threaded cylinder 121 generates thread force with the threaded rod 124. Because the threaded rod 124 is restricted by the lower ring 123 below, it cannot rotate and can only move downwards. Therefore, compared to the downward displacement of the threaded cylinder 121, the threaded rod 82's downward movement is significantly faster. The threaded rod 124 will also generate additional downward displacement, thereby pressing the lower ring 123 against the upper surface of the valve. At this time, the air port of the valve is in a state of being pressed and sealed by the rubber gasket 61. Control the air pump 14 to work, and the air inflation head 13 inflates one of the valve ports of the valve. After inflation is completed, since the other valve ports are sealed by the rubber gasket 61, the air pressure inside the valve will not change when the assembly bolt is finally tightened. If the air pressure gauge 11 does not move, it means that the assembly bolt is finally tightened. If the air pressure gauge 11 changes, the data of the tightening machine 10 needs to be changed and the bolt needs to be tightened again until the air tightness is qualified in the subsequent test. This data is the final tightening data.
