Description

Technical Field

[0001] This utility model belongs to the technical field of performance testing equipment. Background Technology

[0002] Manual pumps, also known as manual hydraulic pumps, are widely used as a simple and convenient hydraulic power source in various fields such as shipbuilding, coal mining machinery, petrochemicals, metallurgy, power generation, and heavy machinery. They are widely accepted by users due to their small size, light weight, portability, and high safety. Their function is to convert the mechanical energy of a power source (such as an electric motor or internal combustion engine) into the pressure energy of a liquid. To ensure the safety and stable operation of manual pumps during use, their performance undergoes comprehensive testing before being released to the market. See [link / reference needed]. Figure 28 This is a commonly used manual hydraulic pump in our company. The two pictures are side views. The entire manual pump consists of two parts: the oil tank M1 and the oil pump M2. Its performance is mainly affected by the joint between the two parts and the sealing performance of some mounting components on the oil pump M2.

[0053] See Figure 1 The entire work frame consists of a platform support A and a support frame B. There are three sets of testing mechanisms of this utility model on the work frame, which can simultaneously test three manual pumps.

[0054] See Figure 2This is a layout diagram of a single testing mechanism placed on workbench 1. Workbench 1 is merely a platform for placing various components. On workbench 1 are installed the side thread testing component 2, the reversing component 3, the testing machine pressurizing device 4, the positioning component 5, and the air pressure regulating component 7. A sealing component 6 is installed under workbench 1 at the manual pump clearance hole 506 corresponding to the positioning component 5. The layout of each component is as follows: Figure 1 The positioning component 5, used to fix the manual pump, is located at the center and foremost end of the workbench 1. A reversing component 3 is installed on the workbench to the left of the manual pump, corresponding to the positioning component 5. The reversing component 3 corresponds to the straight valve core Y on the manual pump and is used to rotate and adjust the straight valve core Y. A side-detection threaded component 2 is installed on the workbench to the right of the manual pump, corresponding to the lateral mounting threaded hole Q of the manual pump, and is used to detect the side threaded hole of the manual pump. A laterally movable testing machine pressurizing device 4 is installed on the workbench to the front of the manual pump (the rear side of the single-unit testing mechanism of this utility model), corresponding to the positioning component 5. 4 is divided into two parts, each capable of performing two-step operations. The first part, the force-applying mechanism, controls the manual pump handle P, used to adjust and test the working performance of the small piston rod sub-assembly inside the manual pump chamber. The second part, the front hole detection component, corresponds to the longitudinal groove Z mounted laterally on the oil pump, used to detect the threaded hole on the top of the manual pump. Above the manual pump mounted on the positioning component 5, an air detection and pressure regulating component 7 is installed. The air detection and pressure regulating component 7 is divided into two parts: an air detection component and a pressure regulating component, which extend into the oil pump M2 through the detection oil inlet N to perform air detection and pressure regulation, respectively. Below the workbench 1 below the manual pump mounted on the positioning component 5, a sealing component 6 is installed, used to seal the oil inlet and outlet X connected to the vehicle body.

[0055] S1. Side thread inspection component 2: The side thread inspection component 2 is installed on the right side between the pressurizing device 4 and the positioning component 5 of the inspection machine; the side thread inspection component 2 is installed on the worktable 1 through two guide rod brackets 201. The tail end of the cylinder body 204 of the thread inspection component is fixedly installed on one guide rod bracket 201, and the top end of the piston rod 202 of the thread inspection component is fixedly installed on the other guide rod bracket 201. A transverse motion platform 210 is installed on the cylinder body 204 of the thread inspection component. A front upright plate 208 and a rear upright plate 207 are fixedly installed on the transverse motion platform 210. The thread inspection component motor 205 is fixedly installed on the rear side of the rear upright plate 207. The motor shaft of the thread inspection component motor 205 passes through the rear upright plate 207 and is connected to the inspection machine through the thread inspection component coupling 203. The tail end of the thread-measuring drive shaft 217 is mounted on the front plate 208 via a bearing. A thread-measuring drive pulley 211 is mounted on the thread-measuring drive shaft 217. A thread-measuring driven shaft 215 is mounted on the front plate 208 via a thread-measuring bearing 214. A thread-measuring driven pulley 212 is mounted on the thread-measuring driven shaft 215 on the side corresponding to the thread-measuring drive pulley 211. A thread hole detection shaft 209 is mounted on the outside of the thread-measuring driven shaft 215 via a mounting pin 216. The thread-measuring drive pulley 211 and the thread-measuring driven shaft 215 are connected by a belt. A side thread detection probe is inserted into the thread hole detection shaft 209.

[0056] The side threaded hole (oil pump transverse mounting threaded hole Q) is a hole with internal threads used to mount the pump body to the vehicle body with bolts and to mate with the bolts. Since the manual pump needs to be operated countless times after installation, its installation needs to be extremely stable. Therefore, the matching requirements between the threaded hole and the bolt are relatively high. Therefore, this utility model sets up a threaded hole detection part (side thread detection component 2 and front thread detection component, the front thread detection component is the front hole detection assembly 401, this paragraph describes the side threaded hole detection part).

[0057] See Figure 2 The side-mounted threaded component 2 is installed on the right side of the overall structure. See details for its structure. Figure 3 and Figure 4The threaded component detection motor 205 is the power source, connected to the threaded component drive shaft 217 via the threaded component detection coupling 203. As shown in the figure, when the threaded component detection motor 205 is working, its motor shaft drives the threaded component coupling 203 and the threaded component drive shaft 217 to rotate simultaneously. Consequently, the threaded component drive pulley 211 also rotates synchronously. Since the threaded component driven pulley 212 is connected to the threaded component drive pulley 211 via a belt, the rotation of the threaded component drive pulley 211 also drives the threaded component driven pulley 212 to rotate synchronously. Simultaneously, the threaded component driven shaft 215, which is fixedly mounted on the threaded component driven pulley 212, also rotates. The manual pump shown in the figure has two side threaded holes (oil pump transverse mounting threaded holes Q), therefore... Figure 3 and Figure 4 Two sets of the side thread hole detection mechanism (including thread hole detection shaft 209, thread detection component passive shaft 215, and thread detection component passive pulley 212) are provided.

[0058] Regarding the connection between the threaded hole detection shaft 209 and the driven shaft 215 of the threaded component: The driven shaft 215 is a cavity structure with a sealed rear end and an open end. A spring is placed inside the cavity. The threaded hole detection shaft 209 is inserted into the driven shaft 215 from the open end. A longitudinal groove is formed on the driven shaft 215, through which the mounting pin 216 passes and is mounted on the threaded hole detection shaft 209. In this way, the threaded hole detection shaft 209 is not only installed inside the driven shaft 215, but can also extend and retract within it. The amount of extension and retraction is limited by the length of the groove. The front end of the threaded hole detection shaft 209 has a thread that matches the side threaded hole. The thread settings are the same as those of the bolts installed on the vehicle body. That is to say, if the thread length, number of threads, and other data of the front end of the threaded hole detection shaft 209 are qualified for the side threaded hole (oil pump transverse mounting threaded hole Q), then the bolts can be installed securely.

[0059] The detection part of the side thread detection component 2 is mounted on the transverse motion platform 210. The movement of the transverse motion platform 210 is accomplished by the moving mechanism below it, which can also be called a slide cylinder. The two guide rod brackets 201 on both sides of the slide cylinder are fixed on the worktable 1. The cylinder body of the slide cylinder (the cylinder body 204 of the thread detection component) can move laterally under the adjustment of air pressure (this utility model). Figure 4 (The direction is determined in the middle), and through this movement, the transverse motion platform 210 mounted on the cylinder body of the slide cylinder and the detection part mounted on it are moved simultaneously.

[0060] S2, Reversing Component 3: The reversing component 3 is installed on the left side between the pressurizing device 4 and the positioning component 5 of the testing machine; the reversing component 3 is installed on the worktable 1 through two reversing component guide rod frames 307, the tail end of the reversing component slide cylinder body 304 is fixedly installed on one reversing component guide rod frame 307, the top end of the reversing component slide cylinder piston rod 306 is fixedly installed on the other reversing component guide rod frame 307, a reversing component slide plate 303 is fixedly installed on the reversing component slide cylinder body 304, a reversing fixing plate 305 is installed on the reversing component slide plate 303, the housing of the right-angle planetary reducer 302 is fixedly installed on the reversing fixing plate 305, the shaft of the right-angle planetary reducer 302 is connected to the reversing fixing plate 305 through bearings, and a reversing rod 308 is installed at the front end of the shaft of the right-angle planetary reducer 302.

[0061] See Figure 2 The commutator 3 is installed on the left side of the overall structure, and its detailed structure is shown in [reference needed]. Figure 7 and Figure 8 This mechanism corresponds to the straight valve core Y on the manual pump. The straight valve core of the manual pump only requires adjustment in two directions. Therefore, the reversing component 3 of this invention adjusts the straight valve core of the manual pump to the corresponding angle, and then checks the oil flow and sealing of the oil circuit within the pump body under the two straight valve core states. The reversing adjustment part of the reversing component 3 is also placed on the slide cylinder, used to adjust the left and right movement of the reversing adjustment part of the reversing component 3 (this left and right movement is based on...). Figure 8 The direction of movement is determined, and its structure and working principle are the same as those of the slide cylinder of the threaded component 2 on the side of section

[0020] .

A floating joint 417 of the force-applying mechanism is installed at the end of the piston rod of the linear motion cylinder 415 that passes through the rear upright plate of the pressure table 402 of the testing machine. A linear motion cylinder 415 of the force-applying mechanism is installed at the front end of the floating joint 417. The motion support block 418, the linear motion support block 418 of the force-applying mechanism, and the linear sliding sleeve 409 of the force-applying mechanism are installed at the bottom of the force-applying mechanism platform 407. The rear upright plate 412 of the force-applying mechanism is installed on the rear side of the force-applying mechanism platform 407. The motor shaft of the force-applying mechanism servo motor 414 passes through the force-applying mechanism reducer 413, passes through the rear upright plate 412 of the force-applying mechanism, and is connected to the torque sensor 411 and the serpentine coupling 408. The serpentine coupling 408 is connected to the force-applying device, and the torque sensor 411 is installed on the force-applying mechanism platform 407.

[0064] See the booster mechanism Figure 10 The existing force-applying mechanism servo motor 414, force-applying mechanism reducer 413, serpentine coupling 408, and torque sensor 411 are connected. A force-applying device is then installed on the serpentine coupling 408 at the front end. This device is then mounted on the force-applying mechanism platform 407 via two supports (front upright plate 406 and rear upright plate 412). The connection to both supports is via bearings. A mechanism capable of forward and backward movement is installed under the force-applying mechanism platform 407. As shown in the diagram, this mechanism includes two power sources (one motor and one cylinder). The force-applying mechanism servo motor 414 drives the front force-applying device to rotate (its rotation principle is described in the section on force-applying devices below). The force-applying mechanism linear motion cylinder 415 drives the force-applying mechanism platform 407 and the force-applying mechanism on it to move forward and backward (see...). Figure 13 When the piston rod of the linear motion cylinder 415 of the force-adding mechanism extends or retracts, it will simultaneously move the linear motion support block 418 of the force-adding mechanism back and forth. This will cause the platform 407 of the force-adding mechanism, which is fixedly connected to it, to move back and forth. However, the direction of this back and forth movement is restricted by the cooperation between the linear slide sleeve 409 and the linear slide rail 410 of the force-adding mechanism. In other words, the back and forth movement of the platform 407 of the force-adding mechanism can only be linear in the direction set by the linear slide rail 410 of the force-adding mechanism.

[0065] S311, Force-applying device: A front upright plate 406 is installed on the force-applying mechanism platform 407; the force-applying device bushing 405 is mounted on the front upright plate 406 via bearings; the force-applying rod 404 is inserted into the force-applying device bushing 405 and is axially fixed by the cooperation of the force-applying rod groove 419, the force-applying rod locking pin 418, and the bushing inner groove 430; the force-applying rod threaded hole 425 at the bottom of the force-applying rod 404 is tightened onto the force-applying locking pin 417 by the force-applying rod nut 416; the two ends of the force-applying locking pin 417 are correspondingly placed in the bushing sliding groove 431 at the bottom of the force-applying device bushing 405; the portion of the force-applying rod 404 protruding from the force-applying device bushing 405 is sleeved. The device is equipped with a force-applying spring 426. The rear end of the force-applying spring 426 abuts against the surface of the force-applying device bushing 405, and the front end of the force-applying spring 426 abuts against the force-applying spring clip 424 on the force-applying rod 404. The top end of the force-applying rod 404 is a sleeve mounting head 421. The mounting slot 423 at the rear end of the sleeve 403 is connected to the sleeve mounting head 421 and is fixed with a pin through the corresponding sleeve mounting head pin hole 420 and sleeve pin hole 422. The rear end of the force-applying device bushing 405 is inserted into the inner shaft 432 of the serpentine coupling 408 and is axially fixed by the cooperation of the bushing groove 427, the bushing clip 428 and the inner groove 433 of the coupling.

[0066] See Figure 11 and Figure 12 This section details the structure of the force-applying device, which is mounted on the foremost serpentine coupling 408. The force-applying device bushing 405 is connected to the front vertical plate 406 via bearings. The rear end of the force-applying device bushing 405 is inserted into the inner shaft 432 of the serpentine coupling 408, and is axially fixed by the engagement of the inner groove 433 of the coupling, the bushing retainer 428, and the bushing groove 427. Specifically, half of the bushing retainer 428 is placed in the bushing groove 427, and the other half is placed in the inner groove 433 of the coupling, thus axially fixing the force-applying device bushing 405 to the inner shaft 432 of the coupling. The inner shaft 432 rotates coaxially with the force-applying device bushing 405. The force-applying device bushing 405 and the serpentine coupling 408 will not be pulled out. This part is restricted by the front upright plate 406. Because the distance between the front upright plate 406 and the rear upright plate 412 of the force-applying mechanism is fixed, and the force-applying device bushing 405 and the front upright plate 406 are installed through bearings, they can only rotate and cannot move back and forth. Therefore, after installation, the force-applying device bushing 405 is always inserted in the serpentine coupling 408 and will not fall out.

[0067] The force-adjusting rod 404 is inserted into the inside of the force-adjusting device bushing 405 from the front end (that is, inserted into the inner hole 429 of the force-adjusting device bushing 405), and the force-adjusting locking pin 417 is installed on the threaded hole (force-adjusting rod threaded hole 425) at the bottom of the force-adjusting rod 404 through the force-adjusting rod nut 416 from the rear end of the force-adjusting device bushing 405. An inner groove 430 is formed along the inner edge of the inner hole 429. The inner groove 430, the force-adjusting rod groove 419, and the force-adjusting rod locking pin 418 are axially locked together, so that the force-adjusting rod 404 rotates synchronously when the force-adjusting device bushing 405 rotates. To prevent the force-adjusting rod 404 from dislodging from inside the force-adjusting device bushing 405, a corresponding notch (shoulder groove 431) is formed at the rear end of the force-adjusting device bushing 405. This notch basically matches both ends of the force-adjusting locking pin 417, that is, both ends of the force-adjusting locking pin 417 are placed within the notch. Figure 11 and Figure 12 As can be seen from the diagram, this utility model sets the force-applying pin 417 in the form of a rectangular cube. The left and right sides of the force-applying pin 417 match the notch, but the axial direction of the notch is greater than the front and rear width of the force-applying pin 417. In this way, the force-applying pin 417 can move back and forth within the notch, but is limited by the length of the notch. Through this structure, the force-applying rod 404 can perform telescopic movement, but will not come out. The front opening of the sleeve 403 corresponds to the manual pump handle P. The small piston rod sub-assembly in the manual pump chamber is adjusted by the manual pump handle P. During manual pump testing, the sleeve 403 rotates with the manual pump handle P to pressurize the chamber, thus detecting whether the manual pump assembly is working properly. The sleeve 403 is installed on the sleeve mounting head 421 at the front end of the force-applying rod 404 through the sleeve pin hole 422, the sleeve mounting head pin hole 420, and the engagement of the pin. After the force-applying rod 404 is inserted into the sleeve 405 of the force-applying device, one end is on the outside of the sleeve 405. A spring (force-applying spring 426) is fitted on this part. The two ends of the spring are respectively pressed between the top of the sleeve 405 and the clamp 424 on the force-applying spring. When the top of the force-applying rod 404 is pushed, the force-applying rod 404 moves with the force-applying clamp 417 in a way that restricts the movement of the sleeve groove 431 (the force-applying clamp 417 can only move within the sleeve groove 431 and neither end will come out, that is, the movement distance of the force-applying rod 404 will not exceed the length of the sleeve groove 431). At this time, the spring is compressed. After the sleeve 403 is connected to the small piston rod sub-assembly, the spring will pressurize the sleeve 403, thereby ensuring that the sleeve 403 is in close contact with the manual pump handle P.

[0068] S32, Front Surface Inspection Component 401: The front surface inspection platform 40108 is mounted on the front surface inspection slide mechanism. The front surface inspection slide mechanism has the same structure as the slide mechanism of the side surface inspection thread component 2. A front surface inspection front upright plate 40104 and a front surface inspection rear upright plate 40106 are mounted on the front surface inspection platform 40108. A front surface inspection front adjustment window 40117 and a front surface inspection rear adjustment window 40121 are respectively opened on the front surface inspection front upright plate 40104 and the front surface inspection rear upright plate 40106. The sill and upper part of the front hole inspection adjustment window 40117 and the front hole inspection rear adjustment window 40121 are both equipped with sill rails 40115 and upper window rails 40119. The front hole inspection pre-adjustment block 40116 and the front hole inspection rear adjustment block 40118 are respectively installed inside the front hole inspection pre-adjustment window 40117 and the front hole inspection rear adjustment window 40121, and their upper and lower ends are respectively engaged with the sill rail 40115 and the upper window rail 40119 via sliding grooves; the front hole inspection motor 40107 is installed... Mounted on the front inspection post-adjustment block 40118, the motor shaft of the front inspection motor 40107 passes through the front inspection post-adjustment block 40118 and is connected to the front inspection post-adjustment block 40118 via a bearing. The rear end of the front inspection drive shaft 40105 is connected to the motor shaft of the front inspection motor 40107 via the front inspection coupling 40113, and the front end of the front inspection drive shaft 40105 is connected to the front inspection adjustment block 40116 via the front inspection drive shaft bearing 40101. 40105 has a front hole inspection drive pulley 40111; the front hole inspection thread hole detection shaft 40103 is mounted on the front hole inspection front plate 40104 via the front hole inspection passive shaft bearing 40102, and the front hole inspection passive pulley 40112 is mounted on the front hole inspection thread hole detection shaft 40103. The front hole inspection drive pulley 40111 and the front hole inspection passive pulley 40112 are connected by a belt; the front hole inspection thread detection probe is inserted into the front hole inspection thread hole detection shaft 40103.

[0069] See Figure 14 , Figure 15 , Figure 16 , Figure 17 The working principle of the front hole detection component 401 is the same as that of the side thread detection component 2, both detecting data such as thread length and number of threads in the threaded hole, except that it corresponds to detecting the three threaded holes Z on the front of the oil pump M2. This part adds a belt tensioning function, see... Figure 15The tensioning function is achieved through structural adjustments of the overall mechanism via active power input. In other words, the overall mechanism with active power input is installed on a structure that can provide tension. The structure for adjusting the tensioning function includes: front-face inspection adjustment block 40116, front-face inspection rear adjustment block 40118, window sill slide rail 40115, and upper window slide rail 40119. The front-face inspection adjustment block 40116 and the front-face inspection rear adjustment block 40118 are two parallel plates, and they are respectively positioned at the openings of the front-face inspection front upright plate 40104 and the front-face inspection rear upright plate 40106 (front-face inspection front adjustment window 40106). The front inspection adjustment block 40116 and the front inspection adjustment block 40118 move laterally within the window opening. In order to keep the front inspection adjustment block 40116 and the front inspection adjustment block 40118 within the window opening, sliding grooves are opened at both ends of the front inspection adjustment block 40116 and the front inspection adjustment block 40118. The sliding grooves at both ends are respectively opened on their respective window sill sliding rails 40115 and window upper sliding rails 40119. In this way, the front inspection adjustment block 40116 or the front inspection adjustment block 40118 can only move laterally within the window opening along their respective window sill sliding rails 40115 and window upper sliding rails 40119, and will not fall out of the window opening. The power input mechanism of the front hole inspection component 401 of this utility model can be installed on the front hole inspection adjustment block 40116 and the front hole inspection rear adjustment block 40118 respectively through bearings. Therefore, when the front hole inspection adjustment block 40116 and the front hole inspection rear adjustment block 40118 move laterally, the power input mechanism also moves laterally. That is, it causes the front hole inspection active pulley 40111 to extend outward, thereby stretching the belt connected between the front hole inspection active pulley 40111 and the front hole inspection passive pulley 40112 (since this utility model corresponds to the inspection of three holes, the front hole inspection passive pulley 40112 and its mounting mechanism are set as three sets), thereby achieving the tensioning function.

[0070] The structure of the three threaded holes Z on the front of the oil pump M2 is the same as the single structure of the transverse mounting threaded hole Q of the oil pump in the side threaded component 2. This step will not be described in detail. The only difference is that the single unit of the transverse mounting threaded hole Q of the oil pump in the side threaded component 2 has two corresponding holes Q, while the single unit of the front threaded hole Z has three corresponding holes Z.

[0071] See Figure 9 To facilitate the movement of the front face inspection component 401, a slide cylinder is installed under the front face inspection table plate 40108 of the front face inspection component 401. This slide cylinder is the same as the slide cylinder of the side face inspection thread component 2 in section

[0020] .

[0072] S4, Positioning component 5: A manual pump lower inspection clearance hole 506 is opened on the positioning base plate 504. A positioning plate 505 is fixedly installed at the front end of the positioning base plate 504. A cylinder fixing plate 502 is installed at the rear end of the positioning base plate 504. The cylinder body of the positioning component cylinder 501 is fixedly installed on the cylinder fixing plate 502. The piston rod of the positioning component cylinder 501 passes through the cylinder fixing plate 502.

[0073] See Figure 18 and Figure 27 As can be seen, positioning component 5 is the device that fixes the manual pump to be tested in the middle position of the entire testing mechanism. See Figure 27 First, align one end of the manual pump body M2 with the positioning plate 505, and position the manual pump handle P on the pump body M2 against the notch in the positioning plate 505. This allows the manual pump handle P and the three threaded holes Z on the pump body M2 to protrude through the notch, which corresponds precisely to the pressurizing device 4 of the testing machine. This facilitates the pressurizing device 4 of the testing machine to adjust the manual pump handle P or test the three threaded holes Z. To ensure that the positioning plate 505 does not obstruct the various components or holes on the manual pump, multiple clearance notches are provided on the positioning plate 505. After the manual pump is placed on the positioning plate 505, the positioning component cylinder 501 is activated, and its piston rod extends forward until it hits the rear end of the manual pump M. The piston rod, in cooperation with the positioning plate 505, securely clamps the manual pump M. As can be seen from the figure, the bottom of the fixed manual pump M (this side is the oil inlet and oil outlet X side) corresponds exactly to the manual pump bottom inspection clearance hole 506. Through this clearance, the sealing connector 606 of the sealing assembly 6 below can pass through the manual pump bottom inspection clearance hole 506 and connect with the oil inlet and oil outlet X.

[0074] pass Figure 1 , Figure 2 and Figure 27 As can be seen from the installation position, the positioning component 5, which has the manual pump installed, is located in the middle of the entire workbench 1. To its left is the reversing component 3, which is used to adjust the direction of the straight valve core Y. To its right is the side detection thread component 2, which detects the side hole Q of the pump body M2. Behind it is the testing machine pressurization device 4, which has the function of pressurizing by adjusting the manual pump handle P and detecting the front hole detection thread Z. Above it is the air detection and pressure regulating component 7, which has the functions of air detection and pressure regulation. Below it is the sealing component 6, which has the functions of sealing and oil injection. Through the matching and correspondence of these positions, the entire manual pump M can be tested in all aspects with one machine.

[0075] S5, Blocking Component 6: A blocking component fixing plate 605 is fixed on the workbench 1, and a blocking component support plate 611 is installed on the lower part of the blocking component fixing plate 605; a blocking component linear guide rail 604 is installed on both sides of the surface of the blocking component fixing plate 605, a blocking component linear slide sleeve 603 is matched and installed on the blocking component linear guide rail 604, a blocking component sliding plate 602 is fixedly installed on the blocking component linear slide sleeve 603, and a blocking component blocking push block 608 is installed on the blocking component sliding plate 602; the cylinder body of the multiplier cylinder 601 is fixedly installed on the blocking component support plate 611. Below, the piston rod of the multiplier cylinder 601 passes through the sealing assembly support plate 611, and a floating push head 609 is installed at the end of the piston rod. The floating push head 609 corresponds to the bottom of the sealing assembly linear slide sleeve 603. A sealing head hook block 607 is installed on the upper surface of the sealing assembly fixing plate 605 between the two sealing assembly linear guide rails 604. The sealing connector 606 is inserted into the sealing through groove of the sealing head hook block 607 from the upper end of the sealing head hook block 607 through the sealing connector hook groove 613. The bottom protruding end of the sealing connector 606 corresponds to the top of the sealing push block 608 of the sealing assembly.

[0076] See Figure 19 and Figure 20 The sealing component 6 is used to seal the oil inlet and outlet X, and is also a device for supplying or discharging oil into the manual pump body through the oil inlet and outlet X. In the figure, there are two sealing heads (sealing connectors 606), corresponding to the oil inlet and outlet respectively. The two sealing heads are hung on the sealing head hook block 607 from the top. That is to say, the sealing heads can extend upwards, but cannot fall downwards. The groove 613 on the sealing connector 606 is similar to a hook. After the sealing connector 606 is inserted into the through groove of the sealing head hook block 607 from the top, it is hung on the sealing head hook block 607 through this groove 613. However, the bottom part of the sealing connector 606 extends out, leaving the oil passage hole 612 exposed. This oil passage hole 612 is connected to the oil reservoir through a hose, which facilitates the flow of oil in the pump body back to the oil reservoir or the injection of oil from the oil reservoir into the pump body.

[0077] In the stationary, non-working state, the two plugs on the plugging assembly 6 are disconnected from the oil inlet and outlet. To achieve sealing, a plugging push block 608 is located below the plugging connector 606. The plugging push block 608 moves upward and pushes the bottom of the plugging connector 606 until both plugging connectors 606 are pushed into the oil inlet or outlet respectively for sealing. The upward pushing of the plugging push block 608 is accomplished by a multiplier cylinder 601. The upper end of the piston rod of the multiplier cylinder 601 is connected to the bottom of the plugging push block 608. When the piston rod of the multiplier cylinder 601 extends, it pushes the plugging push block 608 upward. The sealing component fixing plate 605 and the sealing component support plate 611 are brackets used to install the entire mechanism, while the sealing component sliding plate 602, the sealing component linear sliding sleeve 603, and the sealing component linear guide rail 604 are set to ensure that the sealing component sealing push block 608 can only rise smoothly according to the limited position of the linear guide rail.

[0078] S6, Gas pressure regulating component 7: The bottom of the gas pressure regulating component bracket 706 is fixed on the workbench 1. The gas pressure regulating component mounting plate 705 is mounted on the gas pressure regulating component bracket 706. The gas pressure regulating component moving mechanism is mounted on the gas pressure regulating component mounting plate 705.

[0079] The air pressure regulating component 7 for the manual pump has two functions: one is to perform an air pressure test on the pump body to check for sealing, and the other is to connect to the oil filling port N for testing (this port is only used for testing; in actual use, it is sealed with a plug and is not actually used). Oil is injected through this port to test the sealing of the oil passage within the pump body M2 after gradual pressurization (at this point, the plugging component 6 is sealing the inlet and outlet oil ports, and initial oil filling has been completed, meaning the pump body is full of oil, but the pressure may be insufficient). This allows for the detection of the sealing and pressure resistance after oil filling within the pump body. These two tests further confirm that the manual pump meets all safety performance standards for operation.

[0080] S61. Gas Pressure Regulator Moving Mechanism: The gas pressure regulator moving motor 707 is fixedly mounted on the gas pressure regulator mounting plate 705. The gas pressure regulator lead screw 708 is connected to the motor shaft of the gas pressure regulator moving motor 707. Both ends of the gas pressure regulator lead screw 708 are mounted on the lead screw bracket 713 via bearings. The lead screw bracket 713 is mounted on the gas pressure regulator mounting plate 705. A matching... A slider 715 for the gas detection and pressure regulating component; a slide rail 704 for the gas detection and pressure regulating component is installed on the mounting plate 705 on both sides of the lead screw 708 of the gas detection and pressure regulating component, and a sliding sleeve 714 for the gas detection and pressure regulating component is installed on the slide rail 704; a moving platform 709 for the gas detection and pressure regulating component is installed on the sliding sleeve 714 and the slider 715 of the gas detection and pressure regulating component, and a gas detection component and a pressure regulating component are installed on the moving platform 709 of the gas detection and pressure regulating component.

[0081] Both the gas detection and pressure regulation components are mounted on the moving platform 709 of the gas detection and pressure regulation components. To facilitate the movement of these components to their corresponding positions on the manual pump, a traveling mechanism is installed beneath the moving platform 709 of the gas detection and pressure regulation components. (See...) Figures 21-24 When the moving motor 707 of the air pressure regulating component is turned on, the motor shaft drives the lead screw 708 of the air pressure regulating component to rotate. This causes the slide block 715 of the air pressure regulating component, which is threadedly matched with the lead screw 708, to move laterally on the lead screw 708. This, in turn, causes the moving platform 709 of the air pressure regulating component, which is fixedly connected to the slide block 715, to also move laterally. The slide rail 704 and the sliding sleeve 714 of the air pressure regulating component are designed to make the moving platform 709 of the air pressure regulating component move more smoothly and provide guidance during lateral movement.

[0082] S611, Gas Detection Component: The gas detection component bracket 701 is fixedly installed on the gas detection pressure regulating component moving platform 709. The cylinder body of the gas detection component cylinder 712 is fixed on the gas detection component bracket 701. An inflation chamber 710 is installed under the piston rod of the gas detection component cylinder 712. The inflation chamber 710 is connected to the gas supply equipment through a pipeline. The lower end of the inflation chamber 710 has an inflation pipe 711 connected to it. The inflation pipe 711 is fitted with a sealing ring.

[0083] The gas detection assembly is installed on the left side of the gas detection pressure regulating assembly's moving platform 709 (see...). Figure 21The air detection component bracket 701 is an L-shaped bracket. The cylinder body of the air detection component (air detection component cylinder 712) is fixed on the air detection component bracket 701. The piston rod of the cylinder moves up and down, pushing the lower air chamber 710 and air pipe 711 to rise or fall. When it rises, it is in an idle state. When it falls, it will insert into the oil filling port N for testing (at this time, there is no oil in the pump body M2, but the sealing component 6 has already blocked the oil inlet and outlet). At the same time, the oil filling port N for testing is blocked, and then the air is filled through the air port on the air chamber 710 (see...). Figure 22 The round hole on the side of the inflation chamber 710 (which is connected to the air source and air pump via a hose) is used to inflate the pump body M2 through the inflation chamber 710 and the inflation pipe 711 in sequence to test the sealing performance of the entire pump body.

[0084] S612, Pressure Regulating Component: The cylinder body of the pressure regulating component slide cylinder 702 is fixedly mounted on the moving platform 709 of the air pressure regulating component. A pressure regulating component slide plate 70302 is mounted on the slide 70301 of the pressure regulating component slide cylinder 702. A pressure regulating component servo motor bracket 70305 and a pressure regulating component hanger 70308 are located on the pressure regulating component servo motor 70304. The housing of the pressure regulating component servo motor 70304 is fixed to the pressure regulating component servo motor. On bracket 70305, the motor shaft of the voltage regulating component servo motor 70304 passes through the voltage regulating component servo motor bracket 70305 and is connected to the top end of the voltage regulating component regulating shaft 70307 via the voltage regulating component coupling 70306. The voltage regulating component regulating shaft 70307 is mounted on the voltage regulating component bracket 70308 via bearings. The lower end of the voltage regulating shaft 70307 is hexagonal and is inserted into the inner hexagonal sleeve 70313. 3. The pressure regulating component oil reservoir 70310 is fixedly installed at the lower end of the connecting sleeve 70309, which is placed inside the connecting sleeve 70309. The upper end of the connecting sleeve 70309 is fixedly fixed to the lower surface of the pressure regulating component bracket 70308. The pressure regulating rod mounting base is composed of the pressure regulating rod end 70311 and the hexagonal end 70316 of the pressure regulating rod, which is integrated with the pressure regulating rod end 70311. The hexagonal end 70316 of the pressure regulating rod is placed inside the inner hexagonal sleeve 70313. A pressure regulating rod extension spring 70314 is placed inside the internal hexagonal sleeve 70313 between the pressure regulating end 70316 and the pressure regulating shaft 70307 of the pressure regulating assembly; a reducing joint 70317 is located at the lower end of the oil reservoir 70310 of the pressure regulating assembly, and the outer diameter of the pressure regulating rod end 70311 is in clearance contact with the inner diameter of the reducing joint 70317. A longitudinal oil flow groove 70315 is opened on the pressure regulating rod end 70311, and the bit 70312 is installed on the pressure regulating rod mounting seat.

[0085] The pressure regulating component is the next step after the air pressure testing component has checked the seal. The pressure regulating component is installed on the right side of the moving platform 709 of the air pressure testing component (see...). Figure 21The pressure regulating component slide cylinder 702 is an existing device. Its main structure is that the piston drives the slide to slide on the cylinder surface. The cylinder is fixed on the moving platform 709 of the air pressure regulating component. The entire hydraulic pressure regulating mechanism is installed on the sliding plate 70302 of the pressure regulating component on the sliding plate 70301. The sliding plate 70302 and the entire hydraulic pressure regulating mechanism move up and down with the up and down movement of the sliding plate 70302. (Same as the air pressure component, the upward movement is the idle state and the downward movement is the working state.)

[0086] See the hydraulic pressure regulating mechanism. Figure 25 The pressure regulating component servo motor bracket 70305 is a fixed bracket used to install the pressure regulating component servo motor 70304. The pressure regulating component bracket 70308 (two are provided in this invention) is a limiting bracket, which can both suspend the working part and limit its position. Both pressure regulating component brackets 70308 are connected to the pressure regulating component adjusting shaft 70307 via bearings. The pressure regulating component adjusting shaft 70307 can rotate relative to the pressure regulating component bracket 70308 via the bearings. See the hydraulic pressure regulating mechanism. Figure 26 (Power source removed) The servo motor 70304 and coupling 70306 of the pressure regulating component are the power sources for rotation. The pressure regulating shaft 70307 is the connecting transmission shaft for rotation. The connecting sleeve 70309 and oil storage tank 70310 of the pressure regulating component are used for connection to the oil storage tank (an oil inlet is opened on the oil storage tank 70310 of the pressure regulating component, see...). Figure 25The round hole on the oil storage tank 70310 of the pressure regulating component (this oil inlet is connected to the oil storage tank through a pipeline) provides an oil filling and pressurization tank. It is a fixed part that does not rotate. The connecting sleeve 70309 is connected to the oil storage tank 70310 of the pressure regulating component as a whole and is sealed. The top of the connecting sleeve 70309 is sealed and fixedly installed on the lower surface of the pressure regulating component bracket 70308 at the bottom end, and a sealing ring is installed to prevent the oil inside the connecting sleeve 70309 from being squeezed out from the top. During installation, the pressure regulating rod end 70311 is inserted from the upper end of the connecting sleeve 70309. The rod end of the pressure regulating rod end 70311 will protrude from the reducing joint 70317, while the hexagonal end 70316 of the pressure regulating rod is locked inside the oil reservoir 70310 of the pressure regulating assembly. The hexagonal end (hexagonal end 70316) of the pressure regulating rod end 70311 has two functions: one is to secure the pressure regulating rod end 70311 to the oil reservoir 70310. 11 is inserted into the oil reservoir 70310 of the pressure regulating component from the top. Secondly, the hexagonal shape matches the inner hexagonal shape of the inner hexagonal sleeve 70313 and is inserted into the inside from the bottom. The lower end of the pressure regulating shaft 70307 of the pressure regulating component is also hexagonal and is inserted into the upper end of the inner hexagonal sleeve 70313. In this way, when the pressure regulating shaft 70307 of the pressure regulating component rotates, the inner hexagonal sleeve 70313 and the pressure regulating rod end 70311 also rotate. An axial oil groove (longitudinal oil flow groove 70315) is formed on the wall of the pressure regulating rod end 70311. When the pressure regulating rod end 70311 is inserted into the oil reservoir 70310 of the pressure regulating assembly, one section (upper section) of this oil groove is placed inside the oil reservoir 70310, and the other section (lower section) extends out of the oil reservoir 70310. In this way, the oil injected into the oil reservoir 70310 of the pressure regulating assembly flows out through this oil groove. The screwdriver bit 70312 is connected to the pressure regulating valve in the manual pump. Since it is installed at the end of the pressure regulating rod end 70311, it rotates synchronously when the pressure regulating rod end 70311 rotates, thereby adjusting the pressure of the pressure regulating valve through rotation.

[0087] After the air pressure test is completed, when oil injection and pressure adjustment are required, the pressure regulating component of section S612 ( Figure 25Insert the fitting 70317 into the testing oil inlet N until it completely seals the reducing fitting. At this point, the pressure regulating rod end 70311 and the screwdriver bit 70312 are placed inside the pump body, and the screwdriver bit 70312 is connected to the pressure regulating valve inside the pump body. At this time, the sealing assembly 6 also seals the inlet and outlet oil ports. Then, the oil reservoir 70310 of the pressure regulating assembly and the sealing assembly 6 simultaneously inject oil into the pump body until it is full. Due to the oil pressure inside the pump body and the supply of the sealing assembly 6... When the oil pressure is the same, the sealing component 6 stops injecting oil, while the external hydraulic equipment of the pressure regulating component oil storage tank 70310 continues to slowly supply oil to increase the oil pressure inside the pump body. At this time, the pressure regulating component servo motor 70304 rotates, and at the same time, it drives the pressure regulating component coupling 70306, pressure regulating component pressure regulating shaft 70307, ​​internal hexagonal sleeve 70313, pressure regulating rod end 70311, and screwdriver bit 70312 to rotate synchronously, adjusting the pressure regulating valve inside the pump body to regulate the pressure.

[0088] All cylinders described in this utility model are connected to the air storage tank through air inlet and outlet pipes on the cylinder, and all oil cylinders are connected to the oil supply valve through oil pipes. Some require the addition of pressurized air supply or oil supply equipment.

[0089] This utility model has a tensioning wheel mechanism 206 installed on the front upright plate 208. The tensioning wheel 213 on the tensioning wheel mechanism 206 is located at the belt between the active belt pulley 211 of the detection thread component and the passive shaft 215 of the detection thread component. The structure of the tensioning wheel mechanism 206 is as follows: a half-width slide groove 20604 is opened at one corner of the front upright plate 208. An adjustment limit block 20603 is installed at the corner end of the front upright plate 208 at the outer end of the half-width slide groove 20604. An adjustment slider 20605 is placed in the half-width slide groove 20604 and is fixed to the front upright plate 208 by the adjustment positioning block and bolts. A long adjustment groove 20606 is opened on the front upright plate 208 corresponding to the half-width slide groove 20604. A shaft hole 20601 for mounting the tensioning wheel 213 is opened on the adjustment slider 20605 corresponding to the long adjustment groove 20606. The tensioning wheel 213 is mounted on the shaft 217 by bearings.

[0090] Because the driving pulley 211 of the thread detection component and the driven shaft 215 of the thread detection component are connected by a belt, the belt may loosen during long-term operation. Therefore, a tensioner is needed to adjust the belt tension. This part of the mechanism is designed to tension this belt. See [link / reference]. Figure 5 and Figure 6These two figures show that the tensioning mechanism is installed on both sides of the front upright plate 208. The half-width slide groove 20604 is a groove on the front upright plate 208, and its depth is the same as the thickness of the adjusting slider 20605. That is to say, after the adjusting slider 20605 is placed in the half-width slide groove 20604, its outer surface is flush with the front upright plate 208. The length of the half-width slide groove 20604 is the sliding groove for the adjusting slider 20605. When the adjusting slider 20605 is adjusted to the required tension position, the adjusting slider 20605 is fixed in the groove (half-width slide groove 20604) of the front upright plate 208 by the clamping block 20602 and bolts. The shaft hole 20601 is for mounting the axle 217. When the adjusting slider 20605 is dragged and slides within the half-width slide groove 20604, the axle 217 moves along the long adjusting groove 20606 within the shaft hole 20601. The higher it moves, the greater the tensioning pulley 213 on the axle 217 increases the tension on the belt, thereby increasing the belt tension. The tensioning pulley 213 is connected to the driving pulley 211 and the driven shaft 215 of the thread detection component via the same belt. The tensioning pulley 213 is mounted on the axle 217 via bearings.

[0091] The front inspection front panel 40104 and the front inspection rear panel 40106 of this utility model are equipped with a front inspection front and rear panel connecting plate 40110 on the window side; the front inspection front adjustment block 40116 and the front inspection rear adjustment block 40118 are synchronously positioned and installed through a synchronous positioning plate 40109; a drag thread hole 40120 and a bolt through hole 40114 are respectively opened at the corresponding positions of the synchronous positioning plate 40109 and the front inspection front and rear panel connecting plate 40110, and the drag bolt passes through the bolt through hole 40114 and is threadedly matched with the drag thread hole 40120.

[0092] See Figure 15When the belt needs to be tightened, the front inspection pre-adjustment block 40116 and the front inspection post-adjustment block 40118 need to move in parallel at the same time. However, since they are separate, they cannot achieve the same movement position. Therefore, the front inspection pre-adjustment block 40116 and the front inspection post-adjustment block 40118 are fixedly connected by a synchronous positioning plate 40109. In this way, when the synchronous positioning plate 40109 is dragged, the front inspection pre-adjustment block 40116 and the front inspection post-adjustment block 40118 will move synchronously and remain stable. However, dragging the synchronous positioning plate 40109 by hand is neither safe nor convenient. In this case, a front inspection front and rear upright plate connecting plate 40110 is set between the front and rear upright plates (front inspection front upright plate 40104 and front inspection rear upright plate 40106) to fix them. Then, a drag threaded hole 40120 is opened in the center of the corresponding synchronous positioning plate 40109, and a bolt through hole 40114 is also opened at the corresponding position of the front inspection front and rear upright plate connecting plate 40110. A drag bolt is installed in both the drag threaded hole 40120 and the bolt through hole 40114. When the drag bolt is rotated, due to the thread matching, the synchronous positioning plate 40109 will be pulled (rotated forward) or pushed (rotated backward) to move, while dragging the front inspection front adjusting block 40116 and the front inspection rear adjusting block 40118 to move synchronously.

[0093] The positioning plate 505 of this utility model has a clearance window and clearance notches corresponding to the various protruding parts on the manual pump; a nylon soft sleeve 503 is fitted on the piston rod end of the positioning component cylinder 501.

[0094] See Figure 27 , Figure 28 Because the manual pump has protruding parts, corresponding clearance notches are made at the corresponding positions to ensure the manual pump is securely mounted on the positioning plate 505. After the manual pump is installed on the positioning plate 505, the positioning component cylinder 501 is activated. The piston rod extends from the other end of the manual pump and engages with the positioning plate 505 to clamp the manual pump. However, because the piston rod end has a small cross-section and is made of steel, directly pressing against the rear end of the manual pump could easily damage it. Therefore, a soft nylon sleeve 503 is fitted onto the end of the piston rod to protect the manual pump.

[0095] In this invention, sealing push block limiting posts 610 are installed on the sealing component support plates 611 on both sides of the floating push head 609, with the top of the sealing push block limiting post 610 corresponding to the bottom of the sealing component sealing push block 608.

[0096] A circular shaft 614 is installed on the sliding plate 602 of the sealing component of this utility model, and the sealing push block 608 of the sealing component is fitted onto the circular shaft 614 through the central shaft hole.

[0097] See Figure 20 A typical manual pump has two inlet and outlet ports. This requires inserting two sealing connectors 606 into the sealing head mounting block 607. The sealing push block 608 must simultaneously push both connectors, ensuring a tight seal on both ports. However, in practice, due to external factors, even if the two sealing connectors 606 are on the same plane, the sealing push block 608 may become unbalanced while simultaneously pushing them. This could result in one connector being completely sealed while the other is not. To prevent this from happening, this utility model uses a push block central shaft 614 to install the sealing push block 608 and the sealing component sliding plate 602. In this way, the sealing push block 608 can swing left and right around the push block central shaft 614, and push the two sealing joints 606 arranged in a left-right manner to completely seal the two oil ports. At this time, the push block central shaft 614 is fixed on the sealing component sliding plate 602, while the sealing push block 608 is movable in a left-right swinging manner around the push block central shaft 614. When the sealing pusher 608 is not in operation, its possible flip position cannot be determined. In this case, two sealing pusher limiting posts 610 are installed parallel to each other on the sealing component support plates 611 on both sides of the floating pusher 609. When the floating pusher 609 pulls the pusher central shaft 614 and the sealing pusher 608 down to the idle state, the upper end of the sealing pusher 608 always corresponds to the lower end of the two sealing connectors 606. At this time, the floating pusher 609 is connected to the pusher central shaft 614, and the sealing pusher 608 is hung on the pusher central shaft 614 in the form of a shaft.

[0098] In this invention, an oil storage tank fixing bracket 70303 is installed on the surface of the slide table 70301 at the position corresponding to the oil storage tank 70310 of the pressure regulating component, and the side of the oil storage tank 70310 of the pressure regulating component is fixed on the oil storage tank fixing bracket 70303.

[0099] Since the oil storage tank 70310 of the pressure regulating component is a stationary part and is connected to the connecting sleeve 70309, and its suspension is accomplished by the connection between the upper end of the connecting sleeve 70309 and the pressure regulating component bracket 70308, it is very likely to fall off due to excessive force. In this case, a fixing frame (oil storage tank fixing frame 70303) is set up to help reduce the suspension force between the connecting sleeve 70309 and the pressure regulating component bracket 70308.
