Description

Technical Field

[0001] This utility model relates to the field of casting straightening technology, specifically to a testing device for an integral front subframe. Background Technology

[0002] Lightweight chassis design is an inevitable choice for the country's development of new energy vehicles to reduce energy consumption and emissions. More and more automakers are choosing Al-Si alloy casting to manufacture subframes. Currently, Al-Si alloy subframes are mainly of two types: split and integral. Whether split or integral, castings are prone to deformation during casting, placement, and subsequent heat treatment, leading to issues such as thin walls, misaligned holes, and lack of luster during machining. This affects machining efficiency and wastes machining costs. Therefore, it is necessary to check the machining allowance of each machined part of the integral frame blank to ensure the quality of the casting. Utility Model Content

Furthermore, if terms such as "first" or "second" appear in the description of this utility model, they are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] As shown in the attached drawings, the present invention includes a movable straightening table 1. The top of the movable straightening table 1 is provided with a set of fixed support positioning columns 2 and quick-pressing clamps 3 for pressing the front subframe, a movable support positioning seat 4 for Y-axis positioning of the front subframe, a conformal positioning support seat 5 for X-axis positioning of the front subframe, and a set of go and no-go gauges 6 for inspecting the front subframe.

[0023] The quick-pressing clamp 3 presses the front subframe downwards from the Z-axis direction, the movable support positioning seat 4 positions the side of the front subframe from the Y-axis direction, and the conformal positioning support seat 5 is located at the bottom of the front subframe, so it positions the front subframe in the X-axis direction. The above three components work together to position the shape of the front subframe.

[0024] After the front subframe is positioned, a set of six go / no-go gauges are used to check the deformation of each machining point to ensure the machining allowance.

[0025] The bottom of the mobile orthopedic table 1 is equipped with a pair of directional wheels and a pair of omnidirectional wheels. Each pair of omnidirectional wheels is equipped with a braking device, which can fix the table in place when braked.

[0026] Specifically, there are three fixed support positioning columns 2 and three quick-pressing clamps 3, located below and above the corresponding front subframe, respectively.

[0027] The fixed support positioning column 2 and the quick-pressing clamp 3 are distributed on three of the four corners of the front subframe, that is, one corner is fixed and the other corner is movable. After the front subframe is placed and fixed, it is convenient to check whether each point of the movable corner is within the machining allowance range.

[0028] Furthermore, a side guide limit plate 8 is provided on one side of the go / no-go gauge 6 located below the two steering knuckles. One side of the side guide limit plate 8 is inclined, which facilitates the smooth positioning of the two steering knuckles when the front subframe is placed downwards.

[0029] Preferably, the movable support positioning seat 4 includes a positioning central shaft 10 and a movable positioning plate 11. The two ends of the movable positioning plate 11 are symmetrically provided with positioning posts 12. The middle part of the movable positioning plate 11 is rotatably connected to the positioning central shaft 10. The movable orthopedic table 1 is provided with a pair of limiting seats 13 that cooperate with the outer sides of the two ends of the movable positioning plate 11.

[0030] The movable support positioning seat 4 is located at the front center of the front subframe. The movable positioning plate 11 can swing left and right on the positioning center axis 10. During positioning, the two positioning posts 12 can adjust their positions to fit against the side wall of the front end of the front subframe. The limiting seat 13 is used to limit the maximum swing angle of the movable positioning plate 11.

[0031] Preferably, the conformal positioning support 5 includes a base 15 and a tapered positioning pin 16. The tapered positioning pin 16 has a guide post at its bottom. The base 15 has a guide post mounting hole, and a guide sleeve 18 is provided in the guide post mounting hole. A telescopic spring 19 is provided at the bottom of the guide post mounting hole. The tapered positioning pin 16 is movably inserted into the base 15 through the guide post and the guide sleeve 18.

[0032] There is an inverted V-shaped fork at the bottom center of the front subframe. During positioning, a tapered locating pin 16 engages with the inverted V-shaped fork to center the front of the front subframe along the X-axis. The tapered locating pin 16 can extend and retract vertically, providing some clearance for quick positioning of the front subframe.

[0033] Furthermore, the go / no-go gauges 6 located above and on the side of the front subframe are movably mounted on the mobile orthotic table 1 via hinge supports 20.

[0034] The go / no-go gauge 6 located at the bottom of the front subframe is fixed, while the go / no-go gauges 6 located above and to the side of the front subframe are movable, allowing sufficient clearance for the front subframe during positioning. Specifically, during positioning, the go / no-go gauges 6 located above and to the side of the front subframe are all tilted to one side to provide installation space. After positioning, the go / no-go gauges 6 located above and to the side of the front subframe are manually reset, and the machining points on the top of the side of the front subframe are inspected.
