Description
Technical Field
[0001] The invention relates to a high-performance clutch master cylinder and a detection device, belonging to the technical field of clutch pumps. Background Art
[0002] The clutch master cylinder refers to the part that is connected to the clutch pedal and the clutch booster through an oil pipe. Its function is to collect pedal stroke information and disengage the clutch through the booster. The clutch master cylinder converts the force generated by the clutch pedal into hydraulic pressure and outputs it to the clutch slave cylinder. The clutch slave cylinder converts the hydraulic pressure into thrust, pushing the clutch release bearing, thereby disengaging the clutch.
[0003] The conventional clutch adopts a conventional sealing structure for the fluid supply pipe, that is, a sealing ring, a sealing sheet and the like are used for sealing. This type of seal is prone to aging after the clutch pump is used for a long time, which affects the sealing performance of the pump and is prone to leakage. Summary of the invention
[0004] The technical problem to be solved by the present invention is to provide a high-performance clutch master pump and a detection device, which solves the problem in the prior art that a conventional sealing structure is mostly used between the liquid supply pipe of the pump and the pump body, that is, a sealing ring, a sealing sheet and other structures are used for sealing. This type of seal is prone to aging after the clutch pump is used for a long time, which affects the sealing performance of the pump and is prone to leakage.
[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical scheme: a high-performance clutch master pump, comprising a clutch pump, a liquid supply pipe, a mounting groove, a fixed sleeve, a sliding cavity, a sliding ring and a flexible sealing sleeve, wherein the liquid supply pipe is arranged on the clutch pump and communicated with the inside of the clutch pump, the mounting groove is arranged around the inner wall of the liquid supply pipe, the fixed sleeve is fixed in the mounting groove, the sliding cavity is arranged in the fixed sleeve, the sliding cavity is arranged around the fixed sleeve, a side of the sliding cavity away from the clutch pump is provided with an annular opening arranged around the inner wall of the fixed sleeve, the sliding ring is arranged in the sliding cavity along the axial direction of the fixed sleeve for sliding, the radial section of the flexible sealing sleeve is annular, the flexible sealing sleeve is arranged in the sliding cavity and one end is fixed on the side of the sliding ring away from the clutch pump, the other end of the flexible sealing sleeve extends to the inner side of the fixed sleeve through the annular opening, the end of the flexible sealing sleeve extending to the inner side of the fixed sleeve is retracted along the radial direction of the fixed sleeve toward the axis of the fixed sleeve, a pipeline structure is inserted into the liquid supply pipe, the retracted end of the flexible sealing sleeve abuts against the pipeline structure, and the flexible sealing sleeve is used for sealing between the pipeline structure and the fixed sleeve.
[0006] By adopting the above technical solution, after the pipeline structure is inserted into the liquid supply pipe, the pipeline structure abuts against the part of the flexible sealing sleeve located on the inner side of the fixed sleeve, so that the fixed sleeve interferes with the movement of the pipeline structure. In the process of the pipeline structure being gradually inserted into the liquid supply pipe, the flexible sealing sleeve is gradually withdrawn from the sliding cavity, and the flexible sealing sleeve pulls the sliding ring to move in the direction away from the clutch pump. At this time, the air pressure on the side of the sliding ring facing the clutch pump in the sliding cavity decreases and is less than the atmospheric pressure. Under the action of the atmospheric pressure, the force required to withdraw the flexible sealing sleeve from the sliding cavity increases. At this time, the pressure between the retracted end of the flexible sealing sleeve and the pipeline structure also increases, which can avoid the oil The oil seeps out through the gap between the flexible sealing sleeve and the pipeline structure. At the same time, the contact area between the flexible sealing sleeve and the pipeline structure is larger than that of the traditional sealing ring and sealing sheet. When part of the flexible sealing sleeve is aged, the remaining aged part can still be sealed, which is beneficial to improve the sealing effect at the fixed sleeve, thereby improving the sealing effect at the liquid supply pipe and avoiding oil leakage in the liquid supply pipe when the clutch pump is in use. When the pipeline structure is pulled out of the liquid supply pipe, the sliding ring can reset towards the direction of the clutch pump under the action of atmospheric pressure, so that the flexible sealing sleeve can be used repeatedly, reducing the use cost of the flexible sealing sleeve.
[0007] The present invention is further configured as follows: an abutment block is fixed to one end of the flexible sealing sleeve extending to the inner side of the fixed sleeve, the abutment block is arranged in a circular ring shape and fits tightly with the inner wall of the fixed sleeve, a pressure chamber is opened on the side of the abutment block away from the clutch pump, and the abutment block can abut against the pipeline structure to seal between the pipeline structure and the fixed sleeve.
[0008] By adopting the above technical solution, when the pipeline structure abuts against the abutment block during the process of inserting the pipeline structure into the liquid supply pipe, the pipeline structure continues to insert, and at this time the abutment block is pressed toward the clutch pump by the pipeline structure. Since the air pressure on the side of the sliding ring facing the clutch pump in the sliding cavity is getting lower and lower, under the action of atmospheric pressure, the force driving the sliding ring to move in the direction away from the clutch pump becomes larger, thereby increasing the pressure between the abutment block and the pipeline structure. Since the side of the pressure chamber opening provided by the abutment block abuts against the pipeline structure, the pipeline structure closes the pressure chamber at this time, and the gas in the pressure chamber cannot be discharged, and As the pressure increases, the abutment block gradually undergoes structural deformation, which reduces the volume of the pressure chamber and increases the air pressure in the pressure chamber. When the pipeline structure is inserted into the liquid supply pipe to the limit position, the air pressure in the pressure chamber is greater than the air pressure inside the clutch pump. At this time, even if leakage occurs at the abutment point between the abutment block and the pipeline structure, under the action of the pressure difference, the oil is not likely to leak from the abutment point between the abutment block and the pipeline structure. When the air pressure in the pressure chamber is reduced due to leakage, the leaked oil will fill the pressure chamber. At this time, the flexible sealing sleeve fits tightly against the pipeline structure to avoid oil leakage, which can greatly improve the oil sealing at the liquid supply pipe.
[0009] The present invention is further configured as follows: the pipeline structure includes a threaded end cap, a connecting hose and a connecting rigid pipe, the connecting hose is sleeved on one end of the connecting rigid pipe, the threaded end cap is arranged at the opening of the liquid supply pipe and is threadedly connected to the outer side surface of the liquid supply pipe, and the end of the connecting rigid pipe away from the connecting hose passes through the threaded end cap and is inserted into the inner side of the liquid supply pipe.
[0010] By adopting the above technical solution, even if the oil leaks from the joint between the flexible sealing sleeve and the connecting hard pipe, the leaked oil only remains in the internal space of the liquid supply pipe. At this time, the user can directly observe the presence of oil at the opening of the liquid supply pipe through the threaded end cap. At this time, it can be determined that the pump has a leak. In this way, the user can be prompted to perform maintenance before the oil completely leaks from the liquid supply pipe, thereby avoiding the complete leakage of the oil into the working environment and causing damage to other equipment.
[0011] The present invention is further configured as follows: a slot is provided on a side of the threaded end cap away from the liquid supply pipe, a sealing cover is sleeved at the connection between the connecting hose and the connecting rigid pipe, a clamping block is fixedly provided on the side of the sealing cover facing the threaded end cap, the clamping block extends into the slot to clamp the sealing cover and the threaded end cap, an expansion structure is provided on the sealing cover, and after the expansion structure expands, the sealing cover clamps the connection between the connecting hose and the connecting rigid pipe inwardly.
[0012] The present invention is further configured as follows: the expansion structure includes an inflation channel, an inflation chamber and an inflation layer; the inflation chamber is arranged in a surrounding manner inside the sealing cover; the side of the inflation chamber facing the axis of the sealing cover penetrates the sealing cover; the inflation layer is fixed at the opening of the inflation chamber to close the inflation chamber; the inflation channel is fixed on the side of the sealing cover away from the threaded end cover; one end of the inflation channel extends into the inflation chamber and communicates with the inflation chamber; the inflation channel only allows gas to enter the expansion chamber in one direction.
[0013] By adopting the above technical scheme, when the sealing cover is put on the connection between the connecting hose and the connecting hard pipe, gas is introduced into the expansion chamber through the inflation channel to increase the air pressure in the expansion chamber. Under the action of the air pressure, the expansion layer expands and deforms, thereby increasing the pressure at the connection between the expansion layer and the connecting hose and the connecting hard pipe, thereby clamping the connecting hose and the connecting hard pipe and being able to clamp and seal the connection between the connecting hose and the connecting hard pipe. When the clamping block enters the clamping groove, the sealing cover is clamped with the threaded end cover. At this time, the sealing cover cannot move axially, and at this time, the end of the connecting hard pipe is inserted into the liquid supply pipe to the limit position, thereby completing the installation operation of the connecting hard pipe, ensuring that the connecting hard pipe is always connected to the liquid supply pipe during the use of the clutch pump, and ensuring that the oil will not spray out due to the falling off of the connecting hard pipe.
[0014] A detection device for a high-performance clutch master cylinder comprises a base plate, a connecting block, a sliding rod, a threaded rod, a movable clamping plate, a fixed clamping plate and an adjusting structure. The base plate is arranged horizontally in a rectangular shape, the connecting blocks are respectively fixed at the four corners of the base plate, the threaded rod is rotatably arranged between two opposite base plates, the sliding rod is fixedly arranged between the other two opposite base plates, the sliding rod and the threaded rod are parallel, the fixed clamping plate is vertically fixedly arranged on the base plate, the two ends of the fixed clamping plate in the extension direction are respectively penetrated by the sliding rod and the threaded rod, the movable clamping plate is arranged parallel to the fixed clamping plate, the sliding rod and the threaded rod respectively penetrate the two ends of the movable clamping plate in the extension direction, the threaded rod is threadedly connected to the movable clamping plate, the clutch pump is arranged between the fixed clamping plate and the movable clamping plate, the adjusting structure is arranged on the side of the fixed clamping plate away from the movable clamping plate, and the adjusting structure is used to adjust the depth of the pipeline structure inserted into the liquid supply pipe.
[0015] The present invention is further configured as follows: the adjustment structure includes a second fixed block, an adjustment screw, an adjustment motor, an adjustment plate and an adjustment chamber, the second fixed block is fixedly arranged on the bottom plate, the adjustment chamber is opened in the second fixed block, the adjustment screw is rotatably arranged in the adjustment chamber, the axial direction of the adjustment screw is parallel to the axial direction of the liquid supply pipe, the adjustment plate is slidably arranged in the adjustment chamber along the axial direction of the adjustment screw, the adjustment screw passes through the adjustment plate and is threadedly connected to the adjustment plate, the adjustment motor is fixed on the outside of the second fixed block, the adjustment motor is dynamically connected to the end of the adjustment screw, the adjustment plate is connected to the pipeline structure, and the pipeline structure moves with the adjustment plate.
[0016] By adopting the above technical scheme, during the detection process, the liquid supply pipe is placed toward the side away from the bottom plate, and then the threaded rod is rotated. Under the action of the threaded structure, the movable clamping plate moves along the axial direction of the threaded rod toward the fixed clamping plate, so that the fixed clamping plate and the movable clamping plate clamp the clutch pump, and then the adjustment plate is connected to the pipeline structure. After the adjustment motor is started, it drives the adjustment screw to rotate, so that under the action of the threaded structure, the adjustment plate slides along the axial direction of the adjustment screw, and then the depth of the pipeline structure inserted into the liquid supply pipe is adjusted, so that the detection device can detect the air tightness of different positions in the clutch pump and the liquid supply pipe, avoid missed detection, and greatly improve the detection accuracy of the device.
[0017] The present invention is further configured as follows: a first fixed block is fixedly provided on one side of the adjustment chamber located in the extension direction of the fixed clamping plate, there is a gap between the first fixed block and the second fixed block, a plug-in block is provided in the gap, the plug-in block is slidably connected to the first fixed block on a side facing the second fixed block, a gas storage tank is detachably fixedly provided on the plug-in block, the gas storage tank is provided with an output end, an inflation pipe is fixedly connected to the output end, a connecting joint is plugged into the end of the inflation pipe away from the gas storage tank, and the connecting joint can be docked and connected with the pipeline structure.
[0018] By adopting the above technical scheme, the gas tank can be replaced after use by disassembling the plug-in block, so that the detection equipment does not need to rely on external equipment for multiple long-term detections, and the replacement operation of the gas tank is convenient. It only needs to slide the plug-in block out from the gap between the first fixed block and the second fixed block, and then the gas tank and the plug-in block can be disassembled and replaced, which is conducive to improving the convenience of use of the detection equipment. During the detection, the connecting joint is connected to the pipeline structure. On the premise that the pipeline structure is inserted into the liquid supply pipe, gas can be quickly introduced into the clutch pump to check the air tightness inside the clutch pump.
[0019] The beneficial effects of the present invention are:
[0020] 1. After the pipeline structure is inserted into the liquid supply pipe, the pipeline structure abuts against the part of the flexible sealing sleeve located on the inner side of the fixed sleeve, so that the fixed sleeve interferes with the movement of the pipeline structure. In the process of the pipeline structure gradually being inserted into the liquid supply pipe, the flexible sealing sleeve is gradually withdrawn from the sliding cavity, and the flexible sealing sleeve pulls the sliding ring to move in the direction away from the clutch pump. At this time, the air pressure on the side of the sliding ring facing the clutch pump in the sliding cavity decreases and is less than the atmospheric pressure. Under the action of the atmospheric pressure, the force required to withdraw the flexible sealing sleeve from the sliding cavity increases. At this time, the pressure between the retracted end of the flexible sealing sleeve and the pipeline structure also increases, which can prevent the oil from seeping through the gap between the flexible sealing sleeve and the pipeline structure. At the same time, the contact area between the flexible sealing sleeve and the pipeline structure is larger than that of the traditional sealing ring and sealing sheet. When part of the flexible sealing sleeve is aged, the remaining aged part can still be sealed, which is conducive to improving the sealing effect at the fixed sleeve, thereby improving the sealing effect at the liquid supply pipe, and avoiding the situation of oil leakage in the liquid supply pipe when the clutch pump is in use.
[0021] 2. When the pipeline structure is pulled out from the liquid supply pipe, the sliding ring can reset toward the direction of the clutch pump under the action of atmospheric pressure, so that the flexible sealing sleeve can be used repeatedly, reducing the use cost of the flexible sealing sleeve.

DETAILED DESCRIPTION
[0030] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific illustrations.
[0031] like Figures 3 to 7As shown, the high-performance clutch master cylinder includes a clutch pump 18, a fluid supply pipe 20, a mounting groove 40, a fixed sleeve 41, a sliding cavity 42, a sliding ring 43 and a flexible sealing sleeve 44. The fluid supply pipe 20 is arranged on the clutch pump 18 and communicates with the inside of the clutch pump 18. The mounting groove 40 is arranged around the inner wall of the fluid supply pipe 20. The fixed sleeve 41 is fixed in the mounting groove 40. The sliding cavity 42 is arranged in the fixed sleeve 41. The sliding cavity 42 is arranged around the fixed sleeve 41. The side of the sliding cavity 42 away from the clutch pump 18 is provided with an annular opening arranged around the inner wall of the fixed sleeve 41. The sliding ring 43 is arranged along the axis of the fixed sleeve 41. The flexible sealing sleeve 44 is arranged in a sliding cavity 42, and the radial section of the flexible sealing sleeve 44 is annular. The flexible sealing sleeve 44 is arranged in the sliding cavity 42 and one end is fixed on the side of the sliding ring 43 away from the clutch pump 18. The other end of the flexible sealing sleeve 44 extends to the inside of the fixed sleeve 41 through the annular opening. The end of the flexible sealing sleeve 44 extending to the inside of the fixed sleeve 41 is retracted along the radial direction of the fixed sleeve 41 toward the axis of the fixed sleeve 41. A pipeline structure is inserted into the liquid supply pipe 20, and the retracted end of the flexible sealing sleeve 44 abuts against the pipeline structure. The flexible sealing sleeve 44 is used for sealing between the pipeline structure and the fixed sleeve 41. An abutment block 45 is fixed to one end of the flexible sealing sleeve 44 extending to the inside of the fixed sleeve 41. The abutment block 45 is arranged in an annular shape and fits tightly with the inner wall of the fixed sleeve 41. A pressure chamber 46 is opened on the side of the abutment block 45 away from the clutch pump 18. The abutment block 45 can abut against the pipeline structure to seal between the pipeline structure and the fixed sleeve 41. The pipeline structure includes a threaded end cap 30, a connecting hose 33 and a connecting hard pipe 34. The connecting hose 33 is sleeved on one end of the connecting hard pipe 34. The threaded end cap 30 is arranged at the opening of the liquid supply pipe 20 and is threadedly connected to the outer side of the liquid supply pipe 20. The end of the connecting hard pipe 34 away from the connecting hose 33 passes through the threaded end cap 30 and is inserted into the inner side of the liquid supply pipe 20. The end of the connecting hard pipe 34 facing the clutch pump 18 is inserted into the liquid supply pipe 20 and the end face is tightly abutted with the abutment block 45. The part of the flexible sealing sleeve 44 located in the fixed sleeve 41 fills the gap between the outer curved surface of the connecting hard pipe 34 and the inner side of the fixed sleeve 41, completing the sealing operation after the connecting hard pipe 34 is inserted into the liquid supply pipe 20. The extending direction of the connecting hard pipe 34 passes through the threaded end cap 30, and the gap between the connecting hard pipe 34 and the liquid supply pipe 20 and the threaded end cap 30 is filled and sealed by the sealing rings built into the inner side of the liquid supply pipe 20 and the threaded end cap 30. Under pump body working conditions with lower sealing requirements, the pipeline structure can also be set as an inserted tube, which directly passes through the threaded end cap 30 and extends into the liquid supply pipe 20. The gap between the inserted tube and the liquid supply pipe 20 and the threaded end cap 30 is filled by a sealing ring built into the liquid supply pipe 20 and the threaded end cap 30.
[0032] like Figure 3 to Figure 4As shown, a slot 31 is provided on the side of the threaded end cap 30 away from the liquid supply pipe 20, a sealing cover 32 is sleeved at the connection between the connecting hose 33 and the connecting hard pipe 34, a clamping block 39 is fixedly provided on the side of the sealing cover 32 facing the threaded end cap 30, the clamping block 39 extends into the slot 31 to clamp the sealing cover 32 and the threaded end cap 30, and an expansion structure is provided on the sealing cover 32, and after the expansion structure expands, the sealing cover 32 clamps the connection between the connecting hose 33 and the connecting hard pipe 34 inwardly. The expansion structure includes an inflation channel 35, an inflation chamber 37 and an inflation layer 38. The inflation chamber 37 is arranged in a surrounding manner inside the sealing cover 32. The inflation chamber 37 penetrates the sealing cover 32 on the side facing the axis of the sealing cover 32. The inflation layer 38 is fixed at the opening of the inflation chamber 37 to close the inflation chamber 37. The inflation channel 35 is fixed on the side of the sealing cover 32 away from the threaded end cover 30. One end of the inflation channel 35 extends into the inflation chamber 37 and is connected with the inflation chamber 37. The inflation channel 35 only allows gas to enter the inflation chamber 37 in one direction.
[0033] When the pipeline structure is inserted into the liquid supply pipe 20, the pipeline structure and the part of the flexible sealing sleeve 44 located on the inner side of the fixed sleeve 41 abut against each other, so that the fixed sleeve 41 interferes with the movement of the connecting hard pipe 34. In the process of the pipeline structure gradually being inserted into the liquid supply pipe 20, the flexible sealing sleeve 44 is gradually withdrawn from the sliding cavity 42, and the flexible sealing sleeve 44 pulls the sliding ring 43 to move in the direction away from the clutch pump 18. At this time, the air pressure on the side of the sliding ring 43 in the sliding cavity 42 facing the clutch pump 18 is reduced and is less than the atmospheric pressure. Under the action of the atmospheric pressure, the force required to withdraw the flexible sealing sleeve 44 from the sliding cavity 42 is increased. At this time, the pressure between the retracted end of the flexible sealing sleeve 44 and the pipeline structure is also increased, so that the oil can be prevented from seeping through the gap between the flexible sealing sleeve 44 and the pipeline structure. At the same time, the contact area between the flexible sealing sleeve 44 and the pipeline structure is larger than that of the traditional sealing ring and sealing sheet. When part of the flexible sealing sleeve 44 is aged, the remaining aged part can still be sealed. It is beneficial to improve the sealing effect at the fixed sleeve 41, thereby improving the sealing effect at the liquid supply pipe 20, avoiding oil leakage from the liquid supply pipe 20 when the clutch pump 18 is in use. When the pipeline structure is pulled out from the liquid supply pipe 20, the sliding ring 43 can reset toward the direction of the clutch pump 18 under the action of atmospheric pressure, so that the flexible sealing sleeve 44 can be used repeatedly, reducing the use cost of the flexible sealing sleeve 44.
[0034] When the pipeline structure abuts against the abutment block 45 during the process of inserting the pipeline structure into the liquid supply pipe 20, the pipeline structure continues to insert, and at this time the abutment block 45 is pressed toward the clutch pump 18 by the pipeline structure. Since the air pressure on the side of the sliding ring 43 in the sliding chamber 42 facing the clutch pump 18 is getting lower and lower, under the action of atmospheric pressure, the force driving the sliding ring 43 to move in the direction away from the clutch pump 18 becomes larger, thereby increasing the pressure between the abutment block 45 and the pipeline structure. Since the side of the abutment block 45 where the pressure chamber 46 is provided is abutted against the pipeline structure, the pipeline structure closes the pressure chamber 46 at this time, and the gas in the pressure chamber 46 cannot be discharged, and the abutment block 4 As the pressure increases, the structure gradually deforms, reducing the volume of the pressure chamber 46 and increasing the air pressure in the pressure chamber 46. When the pipeline structure is inserted into the liquid supply pipe 20 to the limit position, the air pressure in the pressure chamber 46 is greater than the air pressure inside the clutch pump 18. At this time, even if leakage occurs at the abutment between the abutment block 45 and the pipeline structure, under the action of the pressure difference, the oil is not easy to leak from the abutment between the abutment block 45 and the pipeline structure. When the air pressure in the pressure chamber 46 is reduced due to leakage, the leaked oil will fill the pressure chamber 46. At this time, the flexible sealing sleeve 44 is tightly fitted with the pipeline structure to prevent oil leakage, which can greatly improve the oil sealing performance at the liquid supply pipe 20.
[0035] Even if the oil leaks from the joint between the flexible sealing sleeve 44 and the connecting hard tube 34, the leaked oil only remains in the internal space of the liquid supply pipe 20. At this time, the user can directly observe the presence of oil at the opening of the liquid supply pipe 20 through the threaded end cap 30. At this time, it can be determined that the pump is leaking. In this way, the user can be prompted to perform maintenance before the oil completely leaks from the liquid supply pipe 20, thereby avoiding the complete leakage of the oil into the working environment and causing damage to other equipment.
[0036] When the sealing cover 32 is sleeved on the connection between the connecting hose 33 and the connecting hard tube 34, gas is introduced into the expansion chamber 37 through the inflation channel 35, so that the air pressure in the expansion chamber 37 increases. Under the action of the air pressure, the expansion layer 38 expands and deforms, thereby increasing the pressure at the connection between the expansion layer 38 and the connecting hose 33 and the connecting hard tube 34, thereby clamping the connecting hose 33 and the connecting hard tube 34 and being able to clamp and seal the connection between the connecting hose 33 and the connecting hard tube 34. When the clamping block 39 enters the clamping groove 31, the sealing cover 32 is clamped with the threaded end cover 30. At this time, the sealing cover 32 cannot move axially, and at this time, the end of the connecting hard tube 34 is inserted into the liquid supply pipe 20 to the limit position, thereby completing the installation operation of the connecting hard tube 34, ensuring that the connecting hard tube 34 is always connected to the liquid supply pipe 20 during the use of the clutch pump 18, and ensuring that the oil will not fall off and spray out due to the connection hard tube 34.
[0037] like Figure 1 to Figure 2As shown, a detection device for a high-performance clutch master cylinder includes a base plate 10, a connecting block 11, a slide bar 12, a threaded rod 13, a movable clamping plate 14, a fixed clamping plate 19 and an adjustment structure. The base plate 10 is horizontally arranged in a rectangular shape, the connecting blocks 11 are respectively fixed at the four corners of the base plate 10, the threaded rod 13 is rotatably arranged between two opposite base plates 10, the slide bar 12 is fixedly arranged between the other two opposite base plates 10, the slide bar 12 and the threaded rod 13 are parallel, and the fixed clamping plate 19 is vertically fixedly arranged on the base plate 10. The two ends of the fixed clamping plate 19 in the extension direction are respectively penetrated by the sliding rod 12 and the threaded rod 13, the movable clamping plate 14 is arranged parallel to the fixed clamping plate 19, the sliding rod 12 and the threaded rod 13 respectively penetrate the two ends of the movable clamping plate 14 in the extension direction, the threaded rod 13 is threadedly connected to the movable clamping plate 14, the clutch pump 18 is arranged between the fixed clamping plate 19 and the movable clamping plate 14, the adjustment structure is arranged on the side of the fixed clamping plate 19 away from the movable clamping plate 14, and the adjustment structure is used to adjust the depth of the pipeline structure inserted into the liquid supply pipe 20. The adjustment structure includes a second fixed block 17, an adjustment screw 21, an adjustment motor 22, an adjustment plate 23 and an adjustment chamber 27. The second fixed block 17 is fixedly arranged on the base plate 10. The adjustment chamber 27 is opened in the second fixed block 17. The adjustment screw 21 is rotatably arranged in the adjustment chamber 27. The axial direction of the adjustment screw 21 is parallel to the axial direction of the liquid supply pipe 20. The adjustment plate 23 is slidably arranged in the adjustment chamber 27 along the axial direction of the adjustment screw 21. The adjustment screw 21 passes through the adjustment plate 23 and is threadedly connected with the adjustment plate 23. The adjustment motor 22 is fixed on the outside of the second fixed block 17. The adjustment motor 22 is dynamically connected to the end of the adjustment screw 21. The adjustment plate 23 is connected to the pipeline structure, and the pipeline structure moves with the adjustment plate 23.
[0038] The adjusting plate 23 is connected or clamped with the sealing cover 32 in the pipeline structure by mortise and tenon. When the two are connected by mortise and tenon, a female groove is opened on the adjusting plate 23. The female groove is opened along the axial direction of the adjusting screw rod 21 but does not penetrate the adjusting plate 23 axially. The opening of the female groove faces the liquid supply pipe 20. A male head 36 is fixedly provided on the sealing cover 32. The male head 36 is inserted into the female groove to complete the mortise and tenon connection. After the adjusting plate 23 and the sealing cover 32 are connected by mortise and tenon, when the adjusting plate 23 moves toward the liquid supply pipe 20, the pressure of the adjusting plate 23 body applies pressure to the male head 36 toward the liquid supply pipe 20, so that the male head 36 drives the sealing cover 32 to press toward the liquid supply pipe 20, and then the clamping block 39 is inserted into the clamping groove 31 and clamped with the clamping groove 31. When the adjusting motor 22 is started in reverse and the adjusting plate 23 moves in the direction away from the liquid supply pipe 20, since the sealing cover 32 and the threaded end cover 30 have been engaged by the clamping block 39 and the clamping groove 31, the male head 36 will slide out of the female groove at this time, completing the separation of the adjusting plate 23 and the sealing cover 32, so that the detection device can adjust the insertion depth of the pipeline structure into the liquid supply pipe 20, and complete the installation of the sealing cover 32 during the process of detecting the air tightness of different positions inside the clutch pump 18, thereby reducing the subsequent assembly steps of the clutch pump 18 and helping to improve the efficiency of the detection and production of the clutch pump 18.
[0039] like Figure 1 to Figure 2 As shown, the regulating chamber 27 is located on one side of the extending direction of the fixed clamping plate 19 and is fixedly provided with a first fixed block 15. There is a gap between the first fixed block 15 and the second fixed block 17. A plug-in block 16 is provided in the gap. The plug-in block 16 is slidably connected to the side of the first fixed block 15 facing the second fixed block 17. A gas storage tank 26 is detachably fixedly provided on the plug-in block 16. The gas storage tank 26 is provided with an output end, and the output end is fixedly connected with an inflatable tube 24. The end of the inflatable tube 24 away from the gas storage tank 26 is plugged with a connecting joint 25, and the connecting joint 25 can be connected with the pipeline structure. The inflatable tube 24 can be directly connected with the inflatable channel 35 and fill the expansion chamber 37 with gas. The inflatable tube 24 is divided into two connection states. When the clutch pump 18 is installed on the detection device, the inflatable tube 24 is connected with the inflatable channel 35. When the clutch pump 18 starts to detect, the inflatable tube 24 is connected with the connecting joint 25. The connecting joint 25 is directly installed at the end of the connecting hose 33.
[0040] During the detection process, the liquid supply pipe 20 is placed toward the side away from the base plate 10, and then the threaded rod 13 is rotated. Under the action of the threaded structure, the movable clamping plate 14 moves axially along the threaded rod 13 toward the fixed clamping plate 19, so that the fixed clamping plate 19 and the movable clamping plate 14 clamp the clutch pump 18, and then the adjustment plate 23 is connected to the pipeline structure. After the adjustment motor 22 is started, it drives the adjustment screw 21 to rotate, so that under the action of the threaded structure, the adjustment plate 23 slides axially along the adjustment screw 21, and then the depth of the pipeline structure inserted into the liquid supply pipe 20 is adjusted, so that the detection device can detect the air tightness of different positions in the clutch pump 18 and the liquid supply pipe 20, avoid missed detection, and greatly improve the detection accuracy of the device.
[0041] By disassembling the plug-in block 16, the gas tank 26 can be replaced after use, so that the detection equipment does not need to rely on external equipment for multiple long-term detections, and the replacement operation of the gas tank 26 is convenient. It only needs to slide the plug-in block 16 out of the gap between the first fixed block 15 and the second fixed block 17, and then the gas tank 26 and the plug-in block 16 can be disassembled and replaced, which is beneficial to improving the convenience of use of the detection equipment. During the detection, the connecting joint 25 is connected to the pipeline structure. On the premise that the pipeline structure is inserted into the liquid supply pipe 20, gas can be quickly introduced into the clutch pump 18 to check the air tightness inside the clutch pump 18.
[0042] When the connecting rigid tube 34 is just inserted into the threaded end cap 30, the threaded end cap 30 is threadedly connected to the liquid supply tube 20. At this time, gas is introduced into the clutch pump 18 through the connecting rigid tube 34 to detect the air tightness of the connection between the liquid supply tube 20 and the threaded end cap 30. When the end of the connecting rigid tube 34 enters the inner side of the fixed sleeve 41, the end face of the connecting rigid tube 34 abuts against the abutment block 45. At this time, gas is introduced into the clutch pump 18 through the connecting rigid tube 34 to detect the air tightness of the connection between the connecting rigid tube 34 and the fixed sleeve 41. That is, the air tightness of two places can be detected at one insertion, which is beneficial to improving the detection efficiency.
