Description

Technical Field

[0001] The utility model relates to the technical field of shape correction fixtures, in particular to a hydraulic shape correction fixture for a sub-frame blank. Background Art

[0002] The subframe can be regarded as the skeleton of the front and rear axles, and is a component of the front and rear axles. The subframe is not a complete frame, but a bracket that supports the front and rear axles and suspension, so that the axles and suspension are connected to the "main frame" through it, and it is customarily called the "subframe". The function of the subframe is to block vibration and noise and reduce their direct entry into the car compartment, so it mostly appears on luxury cars and off-road vehicles, and some cars also install subframes for the engine. The traditional load-bearing body without a subframe has its suspension directly connected to the body steel plate. Therefore, the suspension rocker arm mechanism of the front and rear axles is a loose part, not an assembly. After the birth of the subframe, the front and rear suspensions can be assembled on the subframe first to form an axle assembly, and then this assembly can be installed on the body together. New energy is the main trend of transformation and upgrading of the global automotive industry and green development, and it is also a strategic choice for the leapfrog development of my country's automotive industry. Lightweighting the chassis is an inevitable choice for energy conservation and emission reduction. However, during the casting, placement and subsequent heat treatment of the integral aluminum alloy chassis casting, the overall frame is very easy to deform, and the deformation trend of each part is inconsistent, which makes detection and identification extremely difficult. After the flow to the machining process, the deformed products have thin bushing hole walls, skewed holes, and processing without light, which affects the processing efficiency and wastes processing costs. Through structural analysis, the deformed parts are found, and then the telescopic movement of the hydraulic cylinder is used to correct the deformed parts of the overall frame. At this stage, there is no recognized and effective aluminum alloy chassis subframe correction process in the industry. Some use wooden hammers to press the parts, some use screw tensioning mechanisms to press the deformed parts, and some use hydraulic cylinders to correct them.

[0003] As disclosed in the authorization announcement number CN220739084U, a subframe correction and detection fixture is disclosed, wherein the support clamping mechanism includes a support column (4) and a fixed platform (5), a pressure plate (6) is arranged on the top of the fixed platform (5), and the pressure plate (6) is located above the support column (4), the support column (4) and the fixed platform (5) are respectively mounted on a base plate (1), a group of side blocks (2) are mounted on the base plate (1), a detection rod (7) is hinged on the top of the deformation detection platform (3), and the deformation detection platform (3) is mounted on the base plate (1), and the correction mechanism includes a transverse cylinder (8) and a vertical cylinder (9), and correction clamps (10) are respectively arranged on the ends of the piston rods of the transverse cylinder (8) and the vertical cylinder (9), and the transverse cylinder (8) and the vertical cylinder (9) are respectively mounted on the base plate (1). The utility model has the advantages of ensuring that the blanks sent to the machining process can meet the processing requirements, greatly improving the comprehensive product qualification rate and machining efficiency, and greatly reducing costs. However, it cannot achieve precise correction during use. For this reason, we propose a hydraulic correction fixture for the subframe blank to solve the problem that traditional equipment cannot achieve precise correction. Utility Model Content
