[0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When using it to achieve reciprocating motion, the reduction device can be eliminated, and there is no transmission gap, and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines. 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. The buffer device and the exhaust device depend on the specific application, and other devices are indispensable. The hydraulic cylinder needs to be fixed during the production and processing process. The following problems exist in the existing technology:

[0012] Compared with the prior art, the utility model adopts the above structure to achieve the following beneficial effects:

[0013] 1. Through the setting of the positioning mechanism, the two-way telescopic cylinder drives the two sets of connecting plates and the connecting rod to move towards each other at the same time, and the connecting rod drives the two sets of clamping plates to move towards each other to clamp the bottom end of the hydraulic cylinder and position it in the middle position;

[0014] 2.

[0020] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. The present utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-4 As shown, the utility model provides a positioning and clamping tool for the production and processing of hydraulic cylinders, including a base 1, a support column 2 and a support sleeve 3 are arranged on the base 1, a positioning mechanism 4 is arranged in the support sleeve 3, two groups of support columns 2 are arranged and are located on both sides of the support sleeve 3, a sliding sleeve 5 is provided on the support column 2, and a support column 6 is connected to the side end of the sliding sleeve 5, an upper sleeve 7 is connected between the two groups of support columns 6, and a clamping mechanism 8 is arranged in the upper sleeve 7; the positioning mechanism 4 includes a two-way telescopic cylinder 9 and a clamping plate 10, a bracket 11 is arranged at the middle position of the top side end of the base 1, and the two-way telescopic cylinder 9 is installed on the bracket 1 1, both sides of the output ends of the two-way telescopic cylinder 9 are connected with connecting plates 12, and the ends of the connecting plates 12 are connected with connecting rods 13. The connecting rods 13 are movably arranged through the side walls of the supporting sleeve 3. Two groups of clamps 10 are arranged and movably arranged in the supporting sleeve 3. The two groups of clamps 10 are respectively connected to the ends of the two groups of connecting rods 13. The bottom end of the hydraulic cylinder is placed between the two groups of clamps 10 of the supporting sleeve 3. The two-way telescopic cylinder 9 drives the two groups of connecting plates 12 and the connecting rods 13 to move toward each other at the same time. The connecting rods 13 drive the two groups of clamps 10 to move toward each other to clamp the bottom end of the hydraulic cylinder and position it at the middle position.

[0023] like Figure 1-4 As shown, the clamping mechanism 8 is arranged in four groups in a circular array, and the clamping mechanism 8 includes a screw 14 and a positioning plate 15. The screw 14 is threaded through the side wall of the upper sleeve 7, and the positioning plate 15 is movably arranged on the inner side of the upper sleeve 7 and is screwed to the end of the screw 14. A limiting rod 17 is connected to the outer wall of the positioning plate 15, and the limiting rod 17 is movable through the side wall of the upper sleeve 7. The limiting rod 17 limits the positioning plate 15 to prevent the positioning plate 15 from rotating with the screw 14 when the screw 14 is rotated. When the screw 14 is rotated, the positioning plate 15 is driven to move to one side of the hydraulic cylinder under the threaded transmission action of the screw 14, and the four groups of positioning plates 15 clamp the hydraulic cylinder and position it.

[0024] like Figure 1-4 As shown, the positioning plate 15 is an arc-shaped plate structure, and the clamping plate 10 is a V-shaped plate structure.

[0026] During specific use, the bottom end of the hydraulic cylinder is placed between the two groups of clamping plates 10 of the supporting sleeve 3, and the two-way telescopic cylinder 9 is started. The two-way telescopic cylinder 9 drives the two groups of connecting plates 12 and the connecting rod 13 to move toward each other at the same time. The connecting rod 13 drives the two groups of clamping plates 10 to move toward each other to clamp the bottom end of the hydraulic cylinder and position it in the middle position.
