[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 it is used to achieve reciprocating motion, the deceleration 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.

[0003] When manufacturing hydraulic cylinders, parts need to be processed. For example, end covers need to be punched in a machining center, which requires fixed tooling. However, existing processing tools can only perform fixed processing on a single end cover, which reduces processing efficiency. In addition, the processing time of the machining center is relatively fast, so the operator needs to perform multiple clamping within ten minutes, which is too troublesome and makes the operator too tired. For this reason, we provide a new fixed tooling for hydraulic cylinder manufacturing. Utility Model Content

The screw rod 71 is arranged on the inner side of the clamping plate 5. The extrusion block 72 is threadedly connected to the surface of the screw rod 71 through a threaded hole. Two extrusion blocks 72 are provided and are symmetrically arranged along the longitudinal center line of the screw rod 71. The extrusion block 72 is conically arranged. The rotation support assembly 74 is movably connected to the left and right sides of the surface of the screw rod 71. The limit assembly 73 is fixedly connected to the top of the surface of the extrusion block 72.

[0024] As a technical optimization scheme of the utility model, by setting the extrusion mechanism 7, when the operator puts the workpiece into the processing groove 3 and needs to fix it, the operator rotates the screw rod 71, and then the rotating screw rod 71 drives the extrusion blocks 72 to move closer to each other through the limiting assembly 73, so that the extrusion blocks drive the clamping plates 5 to move, and then the clamping plates 5 move away from each other, so that the clamping plates 5 clamp and fix the workpiece, thereby ensuring the stability of the workpiece processing.

[0025] refer to Figure 3 The sliding assembly 6 includes a sliding block 61 , which is fixedly connected to the left and right sides of the bottom of the clamping plate 5 , and a sliding groove 62 for cooperating with the sliding block 61 is provided inside the tooling body 2 .

[0026] As a technical optimization solution of the utility model, by setting a sliding component 6, the clamping plate 5 is slidably connected to the tooling body 2 through the sliding block 61 and the sliding groove 62. When the extrusion block 72 pushes the clamping plate 5, the clamping plate 5 drives the sliding block 61 to move inside the sliding groove 62, thereby ensuring the stability of the movement of the clamping plate 5.

[0027] refer to Figure 1 The rotating support assembly 74 includes a bearing 741, which is movably connected to the left and right sides of the surface of the screw rod 71. A support frame 742 is fixed to the surface of the bearing 741 through a through hole, and the inner side of the support frame 742 is fixedly connected to the tooling body 2.

[0028] As a technical optimization scheme of the utility model, by setting a rotating support assembly 74, the support frame 742 is fixedly installed on the tooling body 2, and then the screw rod 71 is movably installed on the support frame 742 through the bearing 741, so that the bearing 741 and the support frame 742 provide stable support and rotation for the screw rod 71.

[0029] refer to Figure 1 The limiting assembly 73 includes a limiting block 731, which is fixedly connected to the top of the surface of the extrusion block 72. The extrusion block 72 is slidably connected with a limiting rod 732 through a through hole. The left and right ends of the limiting rod 732 are fixedly connected to the support frame 742.

[0030] As a technical optimization scheme of the utility model, by setting a limit assembly 73, when the extrusion block 72 is moved by rotating the screw rod 71, the extrusion block 72 drives the limit plate to slide on the surface of the limit rod 732, and then the limit rod 732 and the limit block 731 limit the movement of the extrusion block 72, thereby preventing the extrusion block 72 from rotating when the screw rod 71 rotates.

[0031] refer to Figure 1A wrapping pad 8 is pasted on the outer side of the clamping plate 5, and the material of the wrapping pad 8 is natural rubber.

[0032] As a technical optimization solution of the utility model, by setting a wrapping pad 8, when the clamping plate 5 contacts the workpiece, the wrapping pad 8 contacts the workpiece first, and then the wrapping pad 8 wraps the workpiece, thereby improving the stability of the clamping plate 5 clamping the workpiece.

[0033] refer to Figure 1 The right end of the screw rod 71 is fixedly connected with a rotating wheel handle 9, and the rotating wheel handle 9 is used in conjunction with the screw rod 71.

[0034] As a technical optimization solution of the utility model, by providing a rotating wheel handle 9, when the operator needs to use the screw rod 71, the operator can drive the screw rod 71 to rotate by shaking the rotating wheel handle 9, thereby making the rotating wheel handle 9 increase the contact area between the operator's hand and the screw rod 71, making it easier for the operator to use the screw rod 71.

[0035] The working principle and use process of the utility model are as follows: during use, when the operator needs to process the workpiece, the operator puts the workpiece into the processing groove 3, and then the operator shakes the rotating wheel handle 9 to drive the screw rod 71 to rotate through the bearing 741 and the support frame 742, and then the rotating screw rod 71 drives the extrusion block 72 to move closer to each other through the limit block 731 and the limit rod 732, so that the extrusion block 72 squeezes the clamping plate 5, and then the clamping plate 5 moves inside the clamping groove 4 through the sliding block 61 and the sliding groove 62, so that the clamping plates 5 are squeezed away from each other by the extrusion of the extrusion block 72, and then the clamping plate 5 can clamp and fix the workpiece, ensure the stability of the workpiece processing, and then multiple workpieces can be processed, thereby improving work efficiency.

[0036] To sum up: this kind of fixed tooling for manufacturing hydraulic cylinders, by setting up multiple processing grooves 3, when the operator needs to process the workpiece, the operator puts multiple workpieces into the processing grooves 3, and then the extrusion mechanism 7 squeezes the clamping plate 5, so that the clamping plate 5 moves inside the clamping groove 4 through the sliding component 6, and then the clamping plates 5 are moved away from each other, so that the clamping plate 5 clamps and fixes the multiple workpieces, ensuring the stability of processing while improving work efficiency, and solving the problem that the existing processing tooling can only fix and process a single end cover, reducing processing efficiency, and the processing time of the machining center is fast, so the operator needs to perform multiple clamping within ten minutes, which is too troublesome and makes the operator too tired.
