Description

Technical Field

[0001] This utility model belongs to the field of testing technology for split-type rotary oil distributor valves, and specifically relates to a processing inspection tool for split-type rotary oil distributor valves. Background Technology

[0002] Split-type rotary distributor valves, as core components in hydraulic systems for multi-circuit distribution and reversal, are widely used in engineering machinery, marine power, metallurgical equipment, and other fields. Their performance directly affects the operational stability and efficiency of the entire hydraulic system. This type of distributor valve consists of a valve body and a valve core, which work together precisely to achieve oil circuit switching during rotary motion. Therefore, extremely high requirements are placed on the fitting accuracy and dynamic sealing performance. Specifically, the key quality parameters of split-type rotary distributor valves include the inner diameter and outer diameter of the valve body.

[0003] The current announcement is for Chinese utility model patent CN216159782U, which discloses a device for detecting the inner diameter of copper parts. The device includes a sliding plate, a vertical plate, a sliding assembly, and a detection rod. One end of the sliding plate is vertically bolted to the vertical plate, and the sliding assembly is connected to both the vertical plate and the sliding plate. The sliding assembly includes a cylinder, a slider, a horizontal plate, two limiting plates, a guide rod, and a clamping block. The cylinder is bolted to the side wall of the vertical plate, and the piston rod of the cylinder slides through the vertical plate and connects to one of the limiting plates. The two limiting plates are symmetrically fixed to both sides of the horizontal plate. The slider is fixed to the lower surface of the horizontal plate, and a groove is formed on the lower end of the slider, which fits onto a guide rail on the sliding plate. A guide rod is symmetrically fixed between the two limiting plates, and a clamping block is slidably connected to the guide rod. A spring is sleeved on the guide rod, and the spring is located between the clamping block and one of the limiting plates. The upper end of the clamping block clamps the detection rod.

[0004] This patent can only detect the inner diameter, but it cannot detect the specific value of the inner diameter. It can only rely on whether the detection rod can be inserted into the inner hole to determine whether the hole diameter is qualified. Its detection efficiency is low and its accuracy is low. Utility Model Content

[0005] The purpose of this utility model is to provide a split-type rotary oil distributor valve processing inspection tool, which solves the problem that the existing split-type rotary oil distributor valve processing inspection tool can only detect the inner diameter and cannot detect the specific value of the inner diameter. It can only rely on whether the detection rod can be inserted into the inner hole to judge whether the hole diameter is qualified, which has low detection efficiency and low accuracy.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a split-type rotary oil separator processing inspection tool, including a worktable, a sliding mechanism is provided on the worktable, a detection mechanism is provided on the sliding mechanism, a fixing mechanism is provided on one side of the sliding mechanism, and a valve body is provided on the fixing mechanism; The sliding mechanism includes a mounting frame, a fixed column, a limiting groove, a limiting block, a sliding block, and a cylinder. The mounting frame is fixedly mounted on the worktable. There are several mounting frames arranged linearly. The fixed column is fixedly mounted inside the mounting frame. The limiting groove is formed on the surface of the fixed column. The limiting block is slidably connected to the limiting groove. The sliding block is fixedly mounted on the limiting block. The detection mechanism is mounted on the sliding block. The cylinder is mounted on the mounting frame. The telescopic shaft of the cylinder is fixedly connected to the sliding block.

[0007] By adopting the above technical solution, and by setting up a worktable, a sliding mechanism, a detection mechanism, a fixing mechanism, and a valve body, in use, the worktable first fixes the sliding mechanism and the detection mechanism, then the fixing mechanism fixes the valve body to prevent the valve body from shifting during detection, and then the sliding mechanism drives the detection mechanism to move, so that the detection mechanism can detect the inner and outer diameters of the oil inlet and outlet on the valve body. The sliding mechanism includes a mounting frame, a fixing column, a limiting groove, a limiting block, and a sliding block. In use, the mounting frame is fixed on the worktable, and then the fixing column is fixed on the mounting frame. The sliding block is moved by a cylinder, which in turn moves the detection mechanism. While the sliding block is moving, the limiting block and the limiting groove cooperate to limit the sliding block, so that the sliding block can only move on the fixing column.

[0008] Furthermore: the detection mechanism includes a connecting sleeve, a connecting column, a three-jaw chuck, a measuring plate, a displacement sensor, and a probe. The connecting sleeve is fixedly mounted on the sliding block, the connecting column is fixedly mounted on the connecting sleeve, the three-jaw chuck is fixedly mounted on one end of the connecting column, the measuring plate is mounted on the moving block on the three-jaw chuck, the displacement sensor is mounted on the three-jaw chuck, the probe is mounted on the displacement sensor, and the other end of the probe is mounted on the measuring plate.

[0009] Using the above technical solution, by setting up a connecting sleeve, connecting column, three-jaw chuck, measuring plate, displacement sensor, and probe, in use, the three-jaw chuck is connected to the moving block through the cooperation of the connecting sleeve and connecting column. The three-jaw chuck is existing technology (by turning a wrench, the moving block on the three-jaw chuck moves synchronously in the same or opposite directions). Then, the measuring plate is fixedly connected to the moving block on the three-jaw chuck, so that the measuring plate moves synchronously in the same or opposite directions. In the initial state, the displacement sensor detects a displacement of 0. When measuring the inner diameter, the measuring plate is brought into the interior of the oil inlet or outlet, and then the three-jaw chuck moves the measuring plate away until the measuring plate contacts the inner hole wall. At this time, the inner diameter is (displacement data plus measuring plate thickness) * 2. When measuring the outer hole diameter, the inner wall of the measuring plate contacts the outer wall of the hole. At this time, the outer diameter is displacement data * 2. It can accurately measure the diameter of the inner and outer holes and can measure multiple oil outlets simultaneously.

[0010] Furthermore: the fixing mechanism includes a fixing platform, a clamping plate, a spring groove, a sliding groove, a spring, and a pressing block. The fixing platform is fixedly mounted on the worktable, the clamping plate is fixedly mounted at both ends of the fixing platform, the spring groove is formed on the side wall of the clamping plate, the number of spring grooves is several and evenly distributed, the sliding groove is located at one end of the spring groove, the spring is fixedly mounted inside the spring groove, the pressing block is slidably mounted in the sliding groove, and one end of the spring is fixedly connected to the pressing block.

[0011] By adopting the above technical solution, and by setting up a fixed platform, a clamping plate, spring grooves, sliding grooves, springs, and a pressing block, the valve body is placed on the fixed platform during use. The fixed platform can raise the height of the valve body, aligning the oil inlet and outlet of the valve body with the detection mechanism. Then, the clamping plate fixes the valve body. When the valve body enters the clamping plate, the valve body presses against the pressing block, causing the pressing block to move in the sliding groove. Then, the pressing block presses against the spring in the spring groove. The force of the spring restoring its deformation acts in the opposite direction on the valve body, thus fixing the valve body. Since there are several spring grooves and they are evenly arranged, the force of multiple springs restoring their deformation further improves the stability of the valve body.

[0012] Furthermore, the workbench is equipped with a data processing and display component, which is electrically connected to the displacement sensor.

[0013] By adopting the above technical solution, a data processing and display component is set up. In use, the data processing and display component is electrically connected to the displacement sensor. The displacement sensor converts the displacement into a standard current signal through the principle of electromagnetic induction. Then, it is converted into a processable voltage signal through a current-to-voltage conversion circuit. The converted voltage signal is quantized and calculated by the processor, converted into an actual distance value, and displayed on the data processing and display component.

[0014] Furthermore, the end of the card plate near the valve body is provided with an inclined portion.

[0015] By adopting the above technical solution and setting an inclined part, the valve body can be easily placed between the two clamping plates during use.

[0016] Furthermore: a support column is fixedly installed on the lower surface of the workbench, and the number of the support columns is four and they are arranged symmetrically. The support columns are provided with anti-slip pads.

[0017] By adopting the above technical solution, and by setting up support columns and anti-slip pads, the support columns can increase the ground clearance of the workbench during use, making it easier to operate and providing support for the workbench. The anti-slip pads can increase the friction between the support columns and the ground, further improving the stability of the workbench.

[0018] Furthermore, the measuring plate is composed of polytetrafluoroethylene.

[0019] By adopting the above technical solution, the material of the measuring plate is designed to have low hardness and low coefficient of friction, so that it will not produce scratches when in contact with the inner hole, and it has good dimensional stability and minimal deformation at room temperature, so as not to cause measurement errors.

[0020] Furthermore, the contact surfaces of the limiting groove and the limiting block are smoothly configured.

[0021] By adopting the above technical solution, the friction between the contact surfaces of the limiting groove and the limiting block can be reduced by making the limiting groove and the limiting block smooth, so that the limiting block can move better in the limiting groove.

[0022] In summary, this utility model has the following beneficial effects: By setting up a sliding mechanism, during use, the mounting frame is fixed on the worktable, and then the fixed column is fixed on the mounting frame. The sliding block is moved by the cylinder, which in turn moves the detection mechanism. While the sliding block is moving, the sliding block is limited by the cooperation of the limit block and the limit groove, so that the sliding block can only move on the fixed column.

[0023] By setting up a detection mechanism, during use, the three-jaw chuck is connected to the moving block through the cooperation of the connecting sleeve and the connecting column. The three-jaw chuck is existing technology (by turning the wrench, the moving block on the three-jaw chuck moves synchronously in the same or opposite directions). Then, the measuring plate is fixedly connected to the moving block on the three-jaw chuck, so that the measuring plate moves synchronously in the same or opposite directions. In the initial state, the displacement sensor detects a displacement of 0. When measuring the inner diameter, the measuring plate is brought into the interior of the oil inlet or outlet, and then the three-jaw chuck moves the measuring plate away until the measuring plate contacts the inner hole wall. At this time, the inner diameter is (displacement data plus measuring plate thickness) * 2. When measuring the outer hole diameter, the inner wall of the measuring plate contacts the outer wall of the hole. At this time, the outer diameter is displacement data * 2.

[0024] Based on the above improvements, the overall technical effect achieved by this device is that it can measure the specific values ​​of the inner and outer diameters through displacement sensors, and can simultaneously measure multiple oil outlets, thereby improving detection efficiency.

The sliding mechanism 2 includes a mounting frame 201, a fixed column 202, a limiting groove 203, a limiting block 204, a sliding block 205, and a cylinder 206. The mounting frame 201 is fixedly mounted on the workbench 1. There are several mounting frames 201 arranged linearly. The fixed column 202 is fixedly mounted inside the mounting frame 201. The limiting groove 203 is opened on the surface of the fixed column 202. The limiting block 204 is slidably connected in the limiting groove 203.

The telescopic shaft of the cylinder 206 is fixedly connected to the sliding block 205.

[0029] By setting up a worktable 1, a sliding mechanism 2, a detection mechanism 3, a fixing mechanism 4, and a valve body 5, in use, the worktable 1 first fixes the sliding mechanism 2 and the detection mechanism 3, and then the fixing mechanism 4 fixes the valve body 5 to prevent the valve body 5 from shifting during detection. Then, the sliding mechanism 2 drives the detection mechanism 3 to move, so that the detection mechanism 3 can detect the inner and outer diameters of the oil inlet and outlet on the valve body 5. The sliding mechanism 2 includes a mounting frame 201, a fixing column 202, a limiting groove 203, a limiting block 204, and a sliding block 205. In use, the mounting frame 201 is fixed on the worktable 1, and then the fixing column 202 is fixed in the mounting frame 201. The cylinder 206 drives the sliding block 205 to move, thereby activating the detection mechanism 3. While the sliding block 205 is moving, the limiting block 204 and the limiting groove 203 cooperate to limit the sliding block 205, so that the sliding block 205 can only move on the fixing column 202.

[0030] refer to Figure 2 The detection mechanism 3 includes a connecting sleeve 301, a connecting column 302, a three-jaw chuck 303, a measuring plate 304, a displacement sensor 305, and a probe 306. The connecting sleeve 301 is fixedly mounted on the sliding block 205, the connecting column 302 is fixedly mounted on the connecting sleeve 301, the three-jaw chuck 303 is fixedly mounted on one end of the connecting column 302, the measuring plate 304 is mounted on the moving block on the three-jaw chuck 303, the displacement sensor 305 is mounted on the three-jaw chuck 303, the probe 306 is mounted on the displacement sensor 305, and the other end of the probe 306 is mounted on the measuring plate 304.

[0031] By configuring a connecting sleeve 301, a connecting post 302, a three-jaw chuck 303, a measuring plate 304, a displacement sensor 305, and a probe 306, in use, the connecting sleeve 301 and the connecting post 302 cooperate to connect the three-jaw chuck 303 to the moving block. The three-jaw chuck 303 is existing technology (by turning a wrench, the moving blocks on the three-jaw chuck 303 can move synchronously in the same or opposite directions). Then, the measuring plate 304 is fixedly connected to the moving blocks on the three-jaw chuck 303, so that the measuring plate 304 can move synchronously in the same or opposite directions. In the initial state, the displacement sensor 305 detects a displacement of 0. When measuring the inner diameter, the measuring plate 304 is inserted into the oil inlet or outlet, and then the three-jaw chuck 303 moves the measuring plate 304 away until the measuring plate 304 contacts the inner hole wall. At this time, the inner diameter is (displacement data plus the thickness of the measuring plate 304) * 2. When measuring the outer hole diameter, the inner wall of the measuring plate 304 contacts the outer wall of the hole. At this time, the outer diameter is the displacement data * 2. It can accurately measure the diameter of the inner and outer holes and can measure multiple oil outlets simultaneously.

[0032] refer to Figure 4 The fixing mechanism 4 includes a fixing platform 401, a clamping plate 402, a spring groove 403, a sliding groove 404, a spring 405, and a pressing block 406. The fixing platform 401 is fixedly installed on the workbench 1. The clamping plate 402 is fixedly installed at both ends of the fixing platform 401. The spring groove 403 is opened on the side wall of the clamping plate 402. There are several spring grooves 403 and they are evenly arranged. The sliding groove 404 is installed at one end of the spring groove 403. The spring 405 is fixedly installed inside the spring groove 403. The pressing block 406 is slidably installed in the sliding groove 404. One end of the spring 405 is fixedly connected to the pressing block 406.

[0033] By setting up a fixed platform 401, a clamping plate 402, a spring groove 403, a sliding groove 404, a spring 405, and a pressing block 406, the valve body 5 is placed on the fixed platform 401 during use. The fixed platform 401 can raise the height of the valve body 5, aligning the oil inlet and outlet of the valve body 5 with the detection mechanism 3. Then, the clamping plate 402 fixes the valve body 5. When the valve body 5 enters the clamping plate 402, the valve body 5 presses the pressing block 406, causing the pressing block 406 to move in the sliding groove 404. Then, the pressing block 406 presses the spring 405 in the spring groove 403. The force of the spring 405 restoring its deformation acts in the opposite direction on the valve body 5, which has a fixing effect on the valve body 5. Since there are several spring grooves 403 and they are evenly arranged, the force of multiple springs 405 restoring their deformation further improves the stability of the valve body 5.

[0034] refer to Figure 1 The workbench 1 is equipped with a data processing and display component 6, which is electrically connected to the displacement sensor 305. When in use, the data processing and display component 6 is electrically connected to the displacement sensor 305. The displacement sensor 305 converts the displacement into a standard current signal through the principle of electromagnetic induction, and then converts it into a processable voltage signal through a current-to-voltage conversion circuit. The converted voltage signal is quantized and calculated by the processor, converted into an actual distance value, and displayed on the data processing and display component 6.

[0035] refer to Figure 1 The end of the card plate 402 near the valve body 5 is provided with an inclined part 7. By providing the inclined part 7, the valve body 5 can be easily placed between the two card plates 402 during use.

[0036] refer to Figure 1 The lower surface of the workbench 1 is fixedly provided with four support columns 8 arranged symmetrically. Anti-slip pads 9 are provided on the support columns 8. By setting the support columns 8 and the anti-slip pads 9, the support columns 8 can increase the ground clearance of the workbench 1 during use, making it easier to operate and providing support for the workbench 1. The anti-slip pads 9 can increase the friction between the support columns 8 and the ground, further improving the stability of the workbench 1.

[0037] refer to Figure 2 The measuring plate 304 is made of polytetrafluoroethylene. By choosing the material of the measuring plate 304, it has low hardness and low coefficient of friction, so it will not produce scratches when in contact with the inner hole. It also has good dimensional stability and minimal deformation at room temperature, so it will not cause measurement errors.

[0038] refer to Figure 2The contact surfaces of the limiting groove 203 and the limiting block 204 are smoothly designed. By making the surfaces of the limiting groove 203 and the limiting block 204 smooth, the friction between the contact surfaces of the limiting groove 203 and the limiting block 204 can be reduced, allowing the limiting block 204 to move better in the limiting groove 203.

[0039] Brief description of usage: In use, firstly, the mounting frame 201 is fixed on the workbench 1, then the fixing post 202 is fixed in the mounting frame 201. The cylinder 206 drives the sliding block 205 to move, thereby activating the detection mechanism 3. While the sliding block 205 moves, the limiting block 204 and the limiting groove 203 work together to limit the sliding block 205, ensuring it can only move on the fixing post 202. The connecting sleeve 301 and the connecting post 302 work together to connect the three-jaw chuck 303 to the moving block. The three-jaw chuck 303 is existing technology (by turning a wrench, the moving blocks on the three-jaw chuck 303 can move synchronously in the same or opposite directions). The measuring plate 304 is fixedly connected to the moving block on the three-jaw chuck 303, so that the measuring plate 304 moves synchronously in the same direction or in opposite directions. In the initial state, the displacement sensor 305 detects a displacement of 0. When measuring the inner diameter, the measuring plate 304 is brought into the interior of the oil inlet or outlet, and then the three-jaw chuck 303 drives the measuring plate 304 away until the measuring plate 304 contacts the inner hole wall. At this time, the inner diameter is (displacement data plus the thickness of the measuring plate 304) * 2. When measuring the outer diameter, the inner wall of the measuring plate 304 contacts the outer wall of the hole. At this time, the outer diameter is displacement data * 2. The diameters of the inner and outer holes can be accurately measured, and multiple oil outlets can be measured simultaneously. Then, the valve body 5 is placed on the fixed platform 401. The fixed platform 401 can raise the height of the valve body 5, so that the oil inlet of the valve body 5 is aligned with the oil outlet and the detection mechanism 3. Then, the valve body 5 is fixed by the clamping plate 402. When the valve body 5 enters the clamping plate 402, the valve body 5 squeezes the squeezing block 406, so that the squeezing block 406 moves in the sliding groove 404. Then, the squeezing block 406 squeezes the spring 405 in the spring groove 403. The force of the spring 405 restoring its deformation acts in the opposite direction on the valve body 5, which has a fixing effect on the valve body 5. Since there are several spring grooves 403 and they are evenly arranged, the force of multiple springs 405 restoring their deformation further improves the stability of the valve body 5. Finally, the data processing and display component 6 is electrically connected to the displacement sensor 305. The displacement sensor 305 converts the displacement into a standard current signal through the principle of electromagnetic induction, and then converts it into a processable voltage signal through a current-to-voltage conversion circuit. The converted voltage signal is quantized and calculated by the processor, converted into an actual distance value, and displayed on the data processing and display component 6.
