[0034] The telescopic clamping assembly includes mounting ears 502 fixedly arranged at both ends of the loading rod 501, and a guide column 503 is slidingly set on the mounting ears 502, and an elastic member 504 is sleeved on one end of the guide column 503, and the guide column 503 is fixedly connected to the linkage rod 505 at one end away from the loading rod 501, and the top of the linkage rod 505 is fixedly connected to the fixed rod 506, and the top side wall of the fixed rod 506 is fixedly connected to the marking rod 510; in actual use, the hydraulic cylinder is placed in the loading rod 501, and when a certain amount of gas is filled in the hydraulic cylinder, the piston rod of the hydraulic cylinder will extend from the cylinder body and move by pushing the linkage rod 505, thereby driving the guide column 503 to move, and the elastic member 504 will be compressed.

[0035] The rotating support assembly includes a rotating arm 508 rotatably arranged on both sides of the bottom of the loading rod 501, a torsion spring 509 is sleeved on the rotating shaft of the rotating arm 508, and the end of the rotating arm 508 is fixedly connected to the load-bearing rod 507; when actually used, the hydraulic cylinder body can be supported under the action of the load-bearing rod 507. When the hydraulic cylinder is subjected to a downward thrust, when the thrust reaches a certain value, the load-bearing rod 507 drives the rotating arm 508 to rotate.

[0036] The leakage measurement assembly includes a conversion motor 616 fixedly arranged on one side of a movable rod 617, the output shaft end of the conversion motor 616 is fixedly connected to a rotating seat 618, the side wall of the rotating seat 618 is fixedly connected to a support rod 612, a plurality of support rods 612 are provided, the outer wall of the support rod 612 is fixedly connected to an elastic sleeve 615, the telescopic end of the elastic sleeve 615 is fixedly connected to a movable push rod 613, and the support rod 612 between the elastic sleeves 615 is fixedly connected to a sensor controller 614; the side wall of the movable rod 617 away from the conversion motor 616 is fixedly connected to an electric push rod 620, the telescopic end of the electric push rod 620 is fixedly connected to a screening rod 619, and the electric push rod 620 corresponds to the sensor controller 614; In actual use, if the cylinder body of the hydraulic cylinder does not leak, the telescopic end of the hydraulic cylinder will not move after inflation. On the contrary, if the hydraulic cylinder leaks, the linkage rod 505 will drive the telescopic end of the hydraulic cylinder to contract under the action of the elastic member 504. In this process, the fixed rod 506 corresponding to the leaking hydraulic cylinder will move toward the side close to the loading rod 501, and the fixed rod 506 corresponding to the non-leaking hydraulic cylinder will not move. Therefore, during the rotation process, the rotation radius of the fixed rod 506 corresponding to the leaking position is smaller, and the rotation radius of the non-leaking fixed rod 506 is larger. When the fixed rod 506 rotates to the side of the movable push rod 613, the movable rod 617 will drive the movable push rod 613 on one side to move. Since the radius without leakage is larger, when the movable push rod 613 moves toward the side close to the fixed rod 506, if the hydraulic cylinder does not leak, the movable push rod 613 will not move with the fixed rod 506. Contact, on the contrary, if the hydraulic cylinder leaks, the movable push rod 613 will contact the fixed rod 506, the movable push rod 613 will squeeze the elastic sleeve 615, the movable push rod 613 will contact the sensor controller 614, the sensor controller 614 drives the electric push rod 620 to extend, and the screening rod 619 at the bottom of the electric push rod 620 pushes down the hydraulic cylinder to detect and screen the leaking hydraulic cylinder. At the same time, the marking rod 510 on one side of the fixed rod 506 will leave a mark on the movable push rod 613. During continuous testing, since the leakage conditions of multiple hydraulic cylinders may be different, the amplitude of the reset movement of the fixed rod 506 will also be different within the same time. In this case, when a batch of hydraulic cylinders are tested, the device can accurately record the corresponding leakage degree of each hydraulic cylinder, which is convenient for operators to rework the hydraulic cylinders according to the situation, thereby improving the convenience and efficiency of subsequent processing.

[0037] The linkage assembly includes a linkage arm 602 fixedly arranged on the top of the fixed column 603, and one end of the linkage arm 602 close to the movable rod 617 is fixedly connected to the fixed arm 604, and the end of the fixed arm 604 is rotatably connected to the transmission rod 606, and one end of the transmission rod 606 is hinged to the movable rod 617.

[0038] The lifting drive assembly includes an electric lifting rod 4 fixedly arranged on one side of the base plate 1, the telescopic end of the electric lifting rod 4 is fixedly connected to the linkage column 8, a through groove 10 is provided on the side wall of the enclosure 2 on one side of the linkage column 8, a transmission plate 9 is slidably arranged on the through groove 10, one end of the transmission plate 9 is fixedly connected to the linkage column 8, and the end of the transmission plate 9 away from the linkage column 8 is fixedly connected to the linkage arm 602; in actual use, the electric lifting rod 4 can drive the linkage column 8 to move downward, and the linkage column 8 drives the linkage arm 602 at the bottom of the transmission rod 606 to move downward, and the linkage arm 602 moves downward During the process, the fixed columns 603 on both sides of the corresponding bottom can be driven to move downward, and the elastic telescopic cylinder 611 at the bottom of one of the fixed columns 603 drives the installation rod 610 to move downward, and the inflation head 609 at the bottom of the installation rod 610 is docked with the air inlet head at the bottom of the hydraulic cylinder, and the inside of the hydraulic cylinder is inflated under the action of the pump air box 621. The fixed column 603 on the other side drives the hydraulic cylinder that has passed the inspection to move downward through the unloading rod 607. Through the above process, the hydraulic cylinder can be inflated, inspected and screened and unloaded at the same time, thereby improving the processing efficiency of the hydraulic cylinder.

[0039] The material receiving assembly 7 includes a defective box 703 rotatably arranged on one side of the fixed plate 11, a telescopic air guide cylinder 706 is hinged between the defective box 703 and the bottom end and the fixed plate 11, the air outlet end of the telescopic air guide cylinder 706 is connected to the telescopic air guide tube 707, the outer wall of the fixed plate 11 is fixedly connected to the pneumatic lifting cylinder 704, the air inlet end of the pneumatic lifting cylinder 704 is connected to the air outlet end of the telescopic air guide tube 707, and a counting rod 705 is provided on the side wall of the telescopic rod of the pneumatic lifting cylinder 704; the side wall of the fixed plate 11 on one side of the defective box 703 is fixedly connected to the expansion arm 701, and one end of the expansion arm 701 is fixedly connected to the good box 702; when actually in use, the leaking hydraulic cylinder will fall into the defective box 703, and the hydraulic cylinder that does not leak will fall into the good box 702, thereby realizing active classification.

[0040] During the implementation of the present invention, the hydraulic cylinder to be tested is placed on the loading rod 501. Under the action of the loading rod 507, the support of the hydraulic cylinder body can be achieved. Under the action of the driving motor 3, the loading rod 501 on the loading plate 13 can be driven to rotate intermittently through the rotating column 12. During the movement, the electric lifting rod 4 can drive the linkage column 8 to move downward, and the linkage column 8 drives the linkage arm 602 at the bottom of the transmission rod 606 to move downward. During the downward movement of the linkage arm 602, the fixed columns 603 on both sides of the corresponding bottom can be driven downward. The elastic telescopic cylinder 611 at the bottom of one of the fixed columns 603 is provided with The movable mounting rod 610 moves downward, and the inflation head 609 at the bottom of the mounting rod 610 docks with the air inlet head at the bottom of the hydraulic cylinder. Under the action of the pump air box 621, the hydraulic cylinder is inflated. After the inflation is completed, the electric lifting rod 4 moves upward and resets. The inflated loading rod 501 rotates to the bottom of the screening rod 619, and the linkage arm 602 moves downward again. Under the action of the fixed arm 604 and the transmission rod 606, the movable rod 617 can be driven to move horizontally. During the movement, the fixed rod 506 corresponding to the leaking hydraulic cylinder will move to the side close to the loading rod 501, and the fixed rod 506 corresponding to the non-leaking hydraulic cylinder will move to the side close to the loading rod 501. If no movement occurs, the fixed rod 506 corresponding to the leaking position will have a smaller rotation radius during the rotation process, and the fixed rod 506 without leakage will have a larger rotation radius. When the fixed rod 506 rotates to the side of the movable push rod 613, since the radius without leakage is larger, when the movable push rod 613 moves toward the side close to the fixed rod 506, if the hydraulic cylinder does not leak, the movable push rod 613 will not contact the fixed rod 506. On the contrary, if the hydraulic cylinder leaks, the movable push rod 613 will contact the fixed rod 506, and the movable push rod 613 will squeeze the elastic sleeve 615, and the movable push rod 613 will contact the transmission rod 506. The sensor controller 614 contacts the electric push rod 620, and the sensor controller 614 drives the electric push rod 620 to extend. The screening rod 619 at the bottom of the electric push rod 620 pushes the hydraulic cylinder downward, and the hydraulic cylinder will be loosened into the defective box 703. On the contrary, if the hydraulic cylinder is qualified, it will continue to rotate with the carrier plate 13 to the top of the good box 702, and the fixed column 603 will drive the unloading rod 607 to move downward, and the qualified hydraulic cylinder will be pushed into the good box 702. This process not only realizes the continuous and rapid detection of the air tightness of the hydraulic cylinder, but also can classify the hydraulic cylinder according to the detection results, which is convenient for the subsequent classification and processing of the hydraulic cylinder. At the same time, as the number of hydraulic cylinders in the defective box 703 increases, the defective box 703 will rotate, thereby driving the telescopic air guide cylinder 706 to contract, and the gas in the telescopic air guide cylinder 706 is sent into the pneumatic lift cylinder 704 through the telescopic air guide tube 707. The pneumatic lift cylinder 704 will extend, and the number of defective products can be counted under the action of the counting rod 705. For multiple batches of hydraulic cylinders, the device can realize simultaneous detection by batch, and by comparing the lifting and lowering of the counting rod 705, the defective rate is compared, which is convenient for connecting the air tightness of the hydraulic cylinder, and timely adjusting the situation of the hydraulic cylinder production line, solving the problem of insufficient air tightness from the source of production, and improving the production yield of the hydraulic cylinder; at the same time, during the detection process, if the air tightness of the hydraulic cylinder is unqualified, the movable push rod 613 will contact the marking rod 510 to record the information of the defective products, which is convenient for maintenance personnel to classify and process them according to the leakage of the hydraulic cylinder.

[0041] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
