Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a tooling for pressurizing and machining hydraulic cylinders for frame components. Background Technology

[0002] In the field of machining, workpieces with poor rigidity are prone to deformation, and traditional fixtures can easily cause the workpiece to bend as a whole when applying force. Although they can be temporarily flattened during machining, the elastic rebound of the material after release causes the machined surface to lose its accuracy, seriously affecting the flatness, parallelism and other geometric tolerances. Existing hydraulic tooling mostly adopts overall synchronous clamping, which cannot adapt to machining areas that require local avoidance, and lacks effective support in hollow parts of the workpiece, which can easily cause cutting vibration. Summary of the Invention

[0003] (a) Technical problems to be solved In view of this, the present invention provides a hydraulic cylinder pressurization tooling for frame components, which achieves coordinated operation of main clamping and auxiliary clamping through multiple sets of hydraulic pressure plates, and can provide support force for the workpiece from bottom to top, ensuring high-precision processing requirements.

[0004] This utility model also provides an auxiliary hydraulic pressure plate assembly. The three-point hinge design allows the pressure plate to open and close smoothly under the drive of the telescopic rod, and also allows for adaptive fine-tuning of the angle. This ensures uniform distribution of the clamping force, avoids stress concentration, reduces workpiece damage, and significantly improves the reliability of the pressing operation.

[0005] To solve the above problems, a hydraulic tooling with zoned pressure regulation capability is needed. This tooling uses multiple independently controlled hydraulic pressure plates to achieve coordinated operation between the main clamping zone and the auxiliary clamping zone, thereby systematically controlling deformation and springback issues and ensuring high-precision machining requirements.

[0006] (II) Technical Solution The embodiments in this specification provide the following technical solutions: A hydraulic cylinder pressurization tooling for frame components, characterized in that it includes a base, a workpiece placement seat on the base, and a hydraulic pressure plate for applying downward pressure to thin workpieces around the workpiece placement seat; a support cylinder is provided at the bottom of the workpiece placement seat, and a support push rod extends from the support cylinder, the support push rod passing through the workpiece placement seat from bottom to top; the workpiece placement seat has a through hole matching the support push rod; the hydraulic pressure plate includes a main hydraulic pressure plate assembly and an auxiliary hydraulic pressure plate assembly, both of which are provided with cylinders and pressure plates; the main hydraulic pressure plate assembly includes a main telescopic rod, a fixing nut is provided at the top of the main telescopic rod, and the fixing nut, the pressure plate, and the main telescopic rod are connected in sequence; the auxiliary hydraulic pressure plate assembly includes a support bracket and a secondary extension... The auxiliary hydraulic pressure plate assembly comprises a retractable rod, the top of which is connected to the end of the pressure plate, the bottom of which is connected to the top wall of the hydraulic cylinder, and the top of which is connected to the middle of the pressure plate. The workpiece placement seat includes a first boundary extending along the length direction and a second boundary opposite to the first boundary. The main hydraulic pressure plate assembly cooperates with the first boundary, and the auxiliary hydraulic pressure plate assembly cooperates with either the first or second boundary. When processing a thin workpiece, the support push rod extends out of the upper surface of the workpiece placement seat and applies an upward supporting force to the thin workpiece. The main hydraulic pressure plate assembly, which cooperates with the first boundary, applies a continuous downward pressure to the thin workpiece. When processing reaches the area corresponding to the first or second boundary of the auxiliary hydraulic pressure plate assembly, the auxiliary hydraulic pressure plate assembly's auxiliary retractable rod retracts, and the side of the pressure plate away from the auxiliary retractable rod is raised.

[0007] In the above technical solution, the main hydraulic pressure plate assembly is the main clamping plate, and the auxiliary hydraulic pressure plate assembly is the auxiliary clamping plate. The first boundary is set with the main hydraulic pressure plate assembly and the auxiliary hydraulic pressure plate assembly. The main hydraulic pressure plate assembly does not lift or extend during processing and continuously applies downward pressure to the thin workpiece. The second boundary is used to set the auxiliary hydraulic pressure plate assembly, which lifts or extends according to the processing path during processing. The fixing nut of the main hydraulic pressure plate assembly is used to lock the pressure plate to the top of the main telescopic rod, making the pressure plate of the main hydraulic pressure plate assembly easier to replace and maintain. The support cylinder is set at the bottom of the workpiece placement seat, and its support push rod can extend upward to support the middle of the workpiece being processed and prevent the blade from vibrating during processing.

[0008] Furthermore, the auxiliary hydraulic pressure plate assembly includes a first auxiliary hydraulic pressure plate assembly, a second auxiliary hydraulic pressure plate assembly, and a third auxiliary hydraulic pressure plate assembly; multiple first auxiliary hydraulic pressure plate assemblies are provided and placed around the workpiece placement seat.

[0010] Furthermore, both the second auxiliary hydraulic pressure plate assembly and the third auxiliary hydraulic pressure plate assembly include a clearance portion disposed on the pressure plate.

[0011] In the above technical solution, the avoidance part is used to avoid the processing equipment.

[0012] Furthermore, a non-processing area and a processing area are provided on the first boundary side of the thin workpiece; a processing area is provided on the second boundary side of the thin workpiece; the main hydraulic pressure plate assembly is matched with the non-processing area of ​​the first boundary; and an auxiliary hydraulic pressure plate assembly is matched with the processing area of ​​the first boundary and the processing area of ​​the second boundary.

[0013] More specifically, the processing area on the first boundary side of the thin workpiece includes a concave arc-shaped processing area, a convex arc-shaped processing area, and a first linear processing area arranged in sequence; the processing area on the second boundary side includes a second linear processing area; the first linear processing area and the second linear processing area on the first boundary side and the second boundary side are respectively provided with a matching first auxiliary hydraulic pressure plate assembly; the concave arc-shaped processing area is provided with a matching second auxiliary hydraulic pressure plate assembly; and the convex arc-shaped processing area is provided with a matching third auxiliary hydraulic pressure plate assembly.

[0014] Furthermore, the workpiece placement seat is provided with a workpiece positioning block, and the side of the thin workpiece is in contact with the workpiece positioning block.

[0015] In the above technical solution, the workpiece positioning block plays a positioning and placement role when a thin workpiece is placed on the workpiece placement seat.

[0016] Furthermore, the workpiece placement seat includes a pad groove and a pad disposed within the pad groove.

[0017] In the above technical solution, different types of workpieces can be adapted by replacing different pads, without replacing the entire workpiece placement seat, thus improving the versatility of the tooling.

[0018] Furthermore, the pad includes a T-shaped pad and a strip-shaped pad, and the pad groove is matched and connected to the pad.

[0019] In the above technical solution, the T-shaped pad can improve the specific support shape, and the strip pad is used to provide a support plane.

[0020] Furthermore, the base is internally equipped with a pipe connecting the hydraulic pressure plate and the supporting oil cylinder.

[0021] In the above technical solution, the pipeline is used to connect the hydraulic pressure plate to the external control equipment.

[0023] In the above technical solution, the auxiliary hydraulic pressure plate assembly is hinged to the lower end of the support bracket via the bracket mounting protrusion on the cylinder mounting seat, forming a second hinge point. At the same time, the upper end of the support bracket is hinged to the middle of the pressure plate via a first pin, forming a first hinge point. This triangular support structure greatly enhances the stability and overall structural strength of the pressure plate during the pressure process, and can effectively prevent lateral displacement and torsion. The end of the pressure plate is connected to the top of the telescopic rod via a third hinge point, so that the pressure plate can open and close smoothly under the drive of the telescopic rod, and can also adaptively fine-tune the angle.
