An oil hole and a connection port are opened inside the connection valve. A fully enclosed oil-sealing mechanism is arranged inside the connection port. A tubing is slidably connected inside the connection port. A sleeve is fixedly connected to the middle section of the tubing body. A sealing gasket is embedded on one side of the sleeve close to the connection valve, and the sealing gasket contacts the connection valve. A top frame is fixedly connected to one end of the sleeve located inside the connection port. An installation sleeve is fixedly connected to the side of the connection valve and located outside the sleeve. A limit ball is slidably connected inside the installation sleeve.

[0004] However, through the exploration of the inventor, it is found that this technical solution still has at least the following defects:

[0005] In actual use, it is found that in the above technical solution, the hydraulic component is squeezed and fixed by a limit ring, and the limit ring is a plane.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0040] Embodiment 1:

[0041] As Figures 1 to 8 shown, a hydraulic component table position quick-change device includes a connection valve body 1.

[0042] A flipping and pressing assembly is installed on the connection valve body 1. The flipping and pressing assembly includes a pressure roller 2, and a pressing groove 223 and a flipping groove 224 for guiding the position of the pressure roller 2. The two ends of the pressure roller 2 are inclinedly installed with pressure arms 21, and the ends of the pressure arms 21 are movably connected to the pressing groove 223 and the flipping groove 224; when the pressure arms 21 slide along the flipping groove 224, the pressure arms 21 drive the pressure roller 2 to rotate above the hydraulic component, and when the pressure arms 21 slide along the flipping groove 224 to the pressing groove 223, at this time, the horizontal sliding of the pressure arms 21 drives the pressure roller 2 to move downward, and at this time, the pressure roller 2 is in mutual extrusion contact with the hydraulic component, and finally, hydraulic components of different heights can be clamped and fixed.

[0043] A locking assembly is also installed on the connection valve body 1. The locking assembly includes a positioning plate 4 horizontally inserted into the side wall of the pressure roller 2 and used for locking the pressure roller 2. By separating the positioning plate 4 from the pressure roller 2, the unlocking operation of the pressure roller 2 can be performed;

[0044] A sealing assembly is installed on the oil inlet of the connecting valve body 1. The sealing assembly includes a sealing piston 52 inserted into the oil inlet and a guide plate 511 for guiding the movement of the sealing piston 52. A sealing rod 5 is installed on the sealing piston 52, and the sealing rod 5 is slidably connected to a ramp 512 formed on the guide plate 511. The length of the ramp 512 is adapted to the length of the flipping groove 224. When the pressing arm 21 slides in the flipping groove 224, the ramp 512 on the guide plate 511 drives the sealing rod 5 and the sealing piston 52 to move upward, thereby opening the oil inlet. Finally, the effect that the inlet oil is open when the hydraulic component needs to be installed is achieved, avoiding the entry of dust during idle time and reducing the workload of later cleaning.

[0045] A driving assembly is installed on the connecting valve body 1. The driving assembly is used to drive the flipping and pressing assembly to move, and indirectly drives the sealing assembly to unlock the oil inlet.

[0046] As Figures 1 to 8 shown, in the specific implementation, a hydraulic component installation groove 11 is formed at the central position of the connecting valve body 1. The hydraulic component installation groove 11 is adapted to the hydraulic component to be processed. The pressing rollers 2 are placed on both sides of the hydraulic component installation groove 11 to ensure that the pressing rollers 2 do not contact the side wall of the hydraulic component at the initial stage. The extension line of the pressing groove 223 intersects with the hydraulic component installation groove 11. When the pressing rollers 2 rotate to the same plane as the pressing groove 223, the pressing rollers 2 can be placed above the hydraulic component, facilitating later extrusion and fixation.

[0047] As Figures 1 to 8 shown, further, an oil inlet pipe 12 is installed on the bottom side wall of the connecting valve body 1. A sealing cover 121 is connected and communicated with the oil inlet pipe 12. The diameter of the sealing cover 121 is larger than the diameter of the oil inlet pipe 12. The sealing piston 52 is slidably connected to the sealing cover 121, and the length of the sealing piston 52 is greater than the height of the sealing cover 121. The sealing rod 5 is slidably connected to the sealing cover 121, ensuring that the sealing piston 52 can slide completely in the sealing cover 121, and can better open the oil inlet pipe 12.

[0048] Example 2:

[0049] Based on Example 1, the difference from this example is: As Figures 1 to 8As shown in the figure, a connecting seat 211 is rotatably installed at the end of the pressing arm 21. A collar 22 is installed on the connecting seat 211. A positioning roller 222 is movably installed through the inside of the collar 22. Fixing seats 225 are installed at both ends of the positioning roller 222. The bottom of the fixing seat 225 is welded to the connecting valve body 1, and the fixing purpose is achieved through the fixing seat 225. Pressing grooves 223 and flipping grooves 224 are formed on the positioning roller 222. The pressing grooves 223 and the flipping grooves 224 communicate with each other. The pressing groove 223 is a straight groove, and the flipping groove 224 is a spiral groove. The pressing groove 223 is closer to the outer edge side of the connecting valve body 1 than the flipping groove 224. A protrusion 221 is installed inside the collar 22, and the protrusion 221 is slidably arranged in the flipping groove 224, reducing the frictional force during the sliding process through the protrusion 221.

[0050] As Figures 1 to 8 shown, in the specific implementation manner, a sliding sleeve 231 is rotatably installed on the outer wall of the collar 22. A synchronous plate 23 is installed on the sliding sleeve 231. The synchronous plate 23 is horizontally slidably connected to the connecting valve body 1, and the synchronous plate 23 is connected to the output end of the driving component. A limiting rod 24 is installed on the synchronous plate 23. A limiting seat 241 is movably installed on the side wall of the limiting rod 24. The limiting seat 241 is installed on the connecting valve body 1. The end of the limiting rod 24 is connected to the guiding plate 511. The driving component includes a lead screw shaft 31. A lead screw sleeve 232 is meshed and installed on the side wall of the lead screw shaft 31. The lead screw sleeve 232 is connected to the synchronous plate 23. A support platform 32 is installed on the connecting valve body 1. A synchronous motor 3 is installed on the support platform 32. The output end of the synchronous motor 3 is connected to one end of the lead screw shaft 31, and an installation seat 311 is installed at the other end of the lead screw shaft 31. The installation seat 311 is connected to the connecting valve body 1. By driving the rotation of the lead screw shaft 31 connected to the output shaft by the synchronous motor 3, at this time, the lead screw shaft 31 rotates on the installation seat 311, and the lead screw sleeve 232 on the lead screw shaft 31 slides out synchronously. The lead screw sleeve 232 drives the connected synchronous plate 23 to slide at this time. The limiting rod 24 on the synchronous plate 23 slides in the limiting seat 241, achieving the limiting purpose, and the guiding plate 511 connected to the end of the limiting rod 24 slides out synchronously at this time, and the sliding sleeve 231 can be pulled to slide out synchronously at this time.

[0051] Example 3:

[0052] Based on Example 2, the difference from this example is: As Figures 1 to 8As shown in the figure, a sliding cavity 421 is formed inside the connecting valve body 1. A sliding plate 422 is slidably installed inside the sliding cavity 421. A guiding block 42 is installed on the sliding plate 422. The end of the guiding block 42 is inserted into the hydraulic component installation groove 11. A return spring 423 is sleeved on the side wall of the guiding block 42. One end of the return spring 423 is clamped on the sliding plate 422, and the other end of the return spring 423 is clamped on the sliding cavity 421. A push plate 41 is installed on the sliding plate 422. The top of the push plate 41 is connected to the positioning plate 4. The side wall of the push plate 41 is slidably connected to a sliding groove 411 formed on the connecting valve body 1. A guiding rod 412 is installed on the inner side wall of the sliding groove 411, and the guiding rod 412 is slidably connected to the push plate 41. When the hydraulic component is being installed in the hydraulic component installation groove 11, first, the side wall of the hydraulic component will be squeezed by the guiding block 42. At this time, the guiding block 42 with a chamfered surface will slide into the sliding cavity 421, driving the sliding plate 422 in the sliding cavity 421 to slide synchronously. Furthermore, at this time, the return spring 423 is stretched. By means of the return spring 423, it is convenient to maintain the initial state, and the stretched return spring 423 is convenient for later reset. During the sliding process of the sliding plate 422, the push plate 41 on the sliding plate 422 slides in the sliding groove 411 at this time, and the horizontal sliding of the push plate 41 is ensured by the guiding rod 412. The positioning plate 4 at the top of the push plate 41 starts to slide outwards at this time, and finally the positioning plate 4 is separated from the pressure roller 2, thereby unlocking the pressure roller 2.

[0053] As Figures 1 to 8 shown, in the specific implementation manner, a straight plane 513 is installed on the top of the guiding plate 511. One end of the straight plane 513 is connected to the highest point of the slope 512. The sealing rod 5 movably penetrates through the gap between the guiding plates 511. A sliding rod 51 is installed at the end of the sealing rod 5. The sliding rod 51 is slidably connected to the side wall of the guiding plate 511. The sliding rod 51 can slide more stably on the side wall of the guiding plate 511, reducing the sliding friction force.

[0054] As Figures 1 to 8 shown, further, a clamping seat 531 is movably inserted on the side wall of the sealing rod 5. The clamping seat 531 is installed on the side wall of the connecting valve body 1. A top plate 53 is installed on the sealing rod 5. A limiting spring 532 is sleeved on the sealing rod 5 between the top plate 53 and the clamping seat 531. The two ends of the limiting spring 532 are respectively clamped on the top plate 53 and the clamping seat 531. When the sealing rod 5 moves upwards, the sealing rod 5 can slide on the clamping seat 531, and the distance between the clamping seat 531 and the top plate 53 becomes closer, thereby squeezing the limiting spring 532. By means of the squeezed limiting spring 532, it is convenient for later reset.

[0055] The implementation principle of a hydraulic component position quick-change device of the present invention is as follows:

[0056] When the hydraulic component needs to be operated, the operator can install the hydraulic component into the hydraulic component installation groove 11 in the connection valve body 1 so that the connection port of the hydraulic component corresponds to the connection port at the bottom of the hydraulic component installation groove 11.

[0057] During the installation of the above-mentioned hydraulic component in the hydraulic component installation groove 11, first, the side wall of the hydraulic component will be squeezed by the guide block 42. At this time, the guide block 42 with a chamfered surface will slide into the sliding cavity 421, driving the slide plate 422 in the sliding cavity 421 to slide synchronously. Furthermore, the reset spring 423 is stretched at this time. The reset spring 423 facilitates maintaining the initial state, and the stretched reset spring 423 facilitates later reset. During the sliding process of the slide plate 422, the push plate 41 on the slide plate 422 slides in the chute 411 at this time, and the horizontal sliding of the push plate 41 is ensured by the guide rod 412. The positioning plate 4 at the top of the push plate 41 starts to slide outwards at this time. Finally, the positioning plate 4 is separated from the pressure roller 2, thereby unlocking the pressure roller 2.

[0058] Then the operator starts the synchronous motor 3, and the lead screw shaft 31 connected to the output shaft is driven to rotate by the synchronous motor 3. At this time, the lead screw shaft 31 rotates on the mounting seat 311, and the lead screw sleeve 232 on the lead screw shaft 31 slides outwards synchronously. The lead screw sleeve 232 drives the connected synchronous plate 23 to slide at this time. The limit rod 24 on the synchronous plate 23 slides in the limit seat 241, serving the purpose of limiting, and the guide plate 511 connected to the end of the limit rod 24 starts to slide outwards synchronously at this time.

[0059] When the synchronous plate 23 slides, it can drive the sliding sleeve 231 to slide synchronously. The sliding sleeve 231 can exert a horizontal sliding force on the collar 22. At this time, the protrusion 221 on the collar 22 slides on the flipping groove 224. Through the guiding action of the flipping groove 224, the entire collar 22 can rotate at this time. The collar 22 drives the pressure arm 21 and the pressure roller 2 to rotate, so that the pressure roller 2 rotates above the installed hydraulic component.

[0060] During this process, the guide plate 511 is moving, and the sliding rod 51 on the sealing rod 5 slides on the slope 512 of the guide plate 511. Furthermore, the sealing rod 5 connected to the sliding rod 51 can be lifted, and thus the sealing piston 52 at the bottom of the sealing rod 5 slides upwards in the sealing cover 121, thereby opening the oil inlet pipe 12 and avoiding the harm caused by dust falling into the oil inlet pipe 12 during the idle period.

[0061] When the sealing rod 5 moves upwards, the sealing rod 5 can slide on the clamping seat 531. The distance between the clamping seat 531 and the top plate 53 becomes closer, thereby squeezing the limit spring 532. The squeezed limit spring 532 facilitates later reset.

[0062] When the collar 22 moves along the pressing groove 223, the sliding rod 51 on the sealing rod 5 slides on the linear plane 513 at this time, and the sealing assembly will not be driven to move. However, when the collar 22 slides linearly in the pressing groove 223, the end of the pressing arm 21 starts to slide to both sides at this time, and the pressing arm 21 drives the pressing roller 2 at the end to move vertically downward, and then the pressing roller 2 squeezes the hydraulic component at the bottom, and finally the purpose of locking can be achieved.

[0063] Finally, the operator can introduce hydraulic oil through the oil inlet pipe 12 to detect the hydraulic component through the connection valve body 1. The internal structure of the connection valve body 1 is prior art and will not be elaborated here.
