[0002] The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure difference on both sides; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. In the production process of the hydraulic cylinder, a drilling machine is required to drill a hole at the bottom of the cylinder barrel to facilitate the installation of the oil pipe for oil inlet. In the process of drilling, the hydraulic cylinder needs to be clamped to keep it stable and facilitate drilling work.

[0022] The movable block 5 forms a movable structure in the support frame 2 through the first movable groove 3, so that the movable block 5 can move in the first movable groove 3 and is limited and fixed by the first clamping groove 4, and the movable block 5 and the first movable groove 3 are both "T"-shaped, avoiding direct movement out of the support frame 2 when the movable block 5 is moved out of the first clamping groove 4, thereby limiting the movable range of the movable block 5.

[0023] The first clamping frame 7 and the second clamping frame 8 form a threaded movable structure on the drilling table 1 through the connecting block 14 and the second threaded rod 15, and the connecting block 14 and the second threaded rod 15 are threadedly connected, so that the rotation of the second threaded rod 15 drives the first clamping frame 7 and the second clamping frame 8 to move in the same direction, thereby driving the hydraulic cylinder to move, which is convenient for positioning the drilling position of the hydraulic cylinder. At the same time, the front side of the second threaded rod 15 is connected to the motor.

[0024] The extrusion plate 10 forms an extrusion structure in the first clamping frame 7 and the second clamping frame 8 through the first threaded rod 9 and the limit rod, so that the extrusion plate 10 can be driven by the first threaded rod 9 to move up and down, and the extrusion plate 10 is arc-shaped, and the first clamping frame 7 and the second clamping frame 8 have a circular structure inside, so that the extrusion plate 10 and the circular structure inside the first clamping frame 7 and the second clamping frame 8 form a clamping structure, thereby fixing the hydraulic cylinder.

[0025] The extrusion block 13 forms a movable structure in the first clamping frame 7 and the second clamping frame 8 through the second movable groove 11, so that the extrusion block 13 can move in the second movable groove 11 and is limited and fixed by the second card groove 12, and the end of the extrusion block 13 and the second movable groove 11 are in a "T" shape, avoiding direct movement out of the first clamping frame 7 and the second clamping frame 8 when the extrusion block 13 is moved out of the second card groove 12, thereby limiting the movable range of the extrusion block 13.

[0028] Working principle: When using the hydraulic cylinder bottom drilling fixture, first, pull the movable block 5 in the support frame 2 so that the movable block 5 is separated from the limit of the first clamping groove 4 at the bottom of the first movable groove 3, and then adjust it according to the thickness of the hydraulic cylinder to be processed, move the movable block 5 through the first movable groove 3, and then insert it into the corresponding first clamping groove 4, and then pull the extrusion blocks 13 on the first clamping frame 7 and the second clamping frame 8 respectively, so that the extrusion blocks 13 move in the second movable grooves 11 in the first clamping frame 7 and the second clamping frame 8, and adjust to the position corresponding to the thickness of the hydraulic cylinder;

[0029] Then, the hydraulic cylinder is inserted into the first clamping frame 7 and the second clamping frame 8 from one side of the support frame 2. During the insertion process, the limiting wheel 6 of the movable block 5 on the support frame 2 will rotate as the hydraulic cylinder is inserted while fixing the left and right positions of the hydraulic cylinder, thereby increasing the loading speed. After placement is completed, the first threaded rod 9 on the first clamping frame 7 and the second clamping frame 8 is rotated so that the extrusion plate 10 connected thereto fixes the hydraulic cylinder inside the first clamping frame 7 and the second clamping frame 8, and then the motor outside the second threaded rod 15 is started so that the second threaded rod 15 drives the connecting block 14 and the first clamping frame 7 and the second clamping frame 8 on the upper side to drive the hydraulic cylinder to move, thereby moving the position where drilling is required to be moved to the bottom of the drill bit, thereby realizing the positioning of the drilling position, and the debris generated during the drilling process will fall into the collection box 17 from the collection port 16 between the support frame 2 and the first clamping frame 7, thereby facilitating the collection of the debris, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
