[0002] As an important hydraulic component, the core function of the hydraulic cylinder is to convert the hydraulic energy in the hydraulic system into mechanical energy, thereby achieving linear reciprocating motion. Hydraulic cylinders play a key role in various mechanical equipment and industrial equipment, such as excavators, cranes, rolling mills, etc. Its working principle is based on the incompressibility of liquids. When the hydraulic oil is under pressure in the cylinder, the pressure will be evenly transmitted to the piston, causing the piston to produce linear motion. The hydraulic cylinder mainly consists of two parts: the hydraulic cylinder barrel and the movable rod, which is the piston rod. During assembly and processing, the movable rod needs to be inserted into the hydraulic cylinder barrel, and then sealed or oiled.

[0035] The clamping side of the clamping head 331 should be equipped with protective devices such as rubber gaskets to prevent damage to the workpiece surface during clamping.

[0036] Specifically, a piston 111 is fixedly mounted on the top of the movable rod 11, a thread head 112 is slidably disposed on the movable rod 11, and a thread groove 121 for threaded connection with the thread head 112 is correspondingly provided on the inner wall surface of the hydraulic cylinder 12. That is, during installation, the piston 111 is first inserted into the hydraulic cylinder 12, and then the thread head 112 and the thread groove 121 are screwed together.

[0037] Furthermore, the conveying structure also includes a screw sleeve 22 rotatably installed on the top of the mounting block 21 and a screw 23 threadedly connected to the screw sleeve 22. One end of the screw 23 close to the fixing mechanism 4 is rotatably installed on the frame 1. The other end of the screw 23 is provided with a motor 24. The motor 24 is fixedly installed in the frame 1, and the output end of the motor 24 is fixedly connected to the screw 23. The motor 24 is used to drive the screw 23 to rotate when starting, so that the screw sleeve 22 drives the mounting block 21 to slide.

[0038] In addition, if Figure 5As shown, two first rotating rods 32 are hinged at the bottom of the mounting block 21, and the two first rotating rods 32 are symmetrically arranged. One end of the first rotating rod 32 is hinged to the mounting block 21, and the other end of the first rotating rod 32 is hinged to the second rotating rod 33, one end of the second rotating rod 33 is hinged to the first rotating rod 32, and the other end of the second rotating rod 33 is fixedly connected to the clamping head 331, and a connecting block 35 is fixedly installed on the protruding end of the first electric push rod 31, and a fixing block 34 is fixedly installed on the connecting block 35, and the fixed connection between the second rotating rod 33 and the clamping head 331 is hinged to the fixing block 34, and the first electric push rod 31 is used to make the two clamping heads 331 approach each other when extending to clamp the movable rod 11.

[0039] In this embodiment, the first rotating rod 32, the second rotating rod 33, the clamping head 331 and the fixing block 34 are mirror-arranged at both ends of the connecting block 35, that is, two pairs of clamping heads 331 are provided. This arrangement enables the clamping mechanism 3 to have a better clamping effect on the movable rod 11.

[0040] In addition, the top shape of the support seat 42 is adapted to the shape of the hydraulic cylinder 12, and the bottom thereof is arranged in an inverted T shape, such as Figure 6 As shown, a second slide groove 44 for the support seat 42 to slide is provided at the bottom of the frame 1, and a limiting rod 43 for inserting into the opening at one end of the hydraulic cylinder 12 is fixedly installed on the frame 1. The limiting rod 43 is used to cooperate with the support seat 42 to clamp the hydraulic cylinder 12 for processing.

[0041] In a further embodiment, an oil filling hole 122 for injecting hydraulic oil is provided on the hydraulic cylinder 12, and an oil filling gun 13 for injecting hydraulic oil into the oil filling hole 122 is provided on the top of the frame 1. That is to say, after the movable rod 11 and the hydraulic cylinder 12 are assembled, the oil filling operation can be completed directly at the tooling, reducing the labor cost and time cost required for transportation.

[0042] It should be noted that the first slide groove 25 and the second slide groove 44 not only provide tracks for the sliding of the mounting block 21 or the support seat 42, but are also used to limit the mounting block 21 or the support seat 42 to prevent them from shifting during the sliding process.

[0043] It should be noted that the support seat 42 and the clamping head 331 should be at the same horizontal height to ensure that after the support seat 42 places the hydraulic cylinder 12 and the clamping head 331 clamps the movable rod 11, the axis of the movable rod 11 can coincide with the axis of the hydraulic cylinder 12 to avoid the problem of inaccurate holes during installation.

[0044] Working principle: When processing, first align the opening of the closed end of the hydraulic cylinder 12 with the limit rod 43 of the frame 1, then lift the closed end of the hydraulic cylinder 12 to retract the second electric push rod 41, and then put the hydraulic cylinder 12 down when the support seat 42 reaches the bottom of the hydraulic cylinder 12. At this time, the hydraulic cylinder 12 is limited by the support seat 42 and the limit rod 43, and then place the movable rod 11 between the clamping heads 331, open the first electric push rod 31, and extend the telescopic end of the first electric push rod 31. At this time, the first rotating rod 3 2, the ends away from the mounting block 21 are brought close to each other, so that the ends of the second rotating rod 33 close to the mounting block 21 are brought close to each other, so that the clamping heads 331 are brought close to each other, and the movable rod 11 is clamped. Then the motor 24 is started to drive the screw rod 23 to rotate. Since the screw sleeve 22 and the top of the mounting block 21 are rotatably connected, and the mounting block 21 is limited in the first slide groove 25, the screw sleeve 22 will rotate and drive the mounting block 21 to move, so that the piston 111 gradually enters the cavity of the hydraulic cylinder barrel 12, and then the thread head 112 and the thread groove 121 are screwed tightly. When the installation is completed, the oil injection gun 13 can be directly pulled down to inject hydraulic oil into the oil injection hole 122 to complete the oil injection operation.

[0045] It should be noted that, in the specific setting, a device with adjustable length of the electric push rod can be provided at the mounting block 21, so that the device can adapt to the assembly of the movable rod 11 and the hydraulic cylinder barrel 12 of hydraulic cylinders of more sizes and meet more production and processing requirements.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
