Description

Technical Field

[0001] The utility model relates to the technical field of shape correction tools, in particular to a shape correction tool for detecting aluminum alloy die castings. Background Art

[0002] Aluminum alloy die castings refer to aluminum alloy equipment and devices obtained by casting. Generally, they are made by pouring heated liquid aluminum alloy into the mold cavity using a sand mold or a metal mold. The crossbeams and tube beams on the car and other cylindrical or slender die castings are also made of aluminum alloy die casting. Since aluminum alloy die castings are softer than steel and iron parts, they are easy to deform, especially the slender structure is easy to bend during the subsequent processing and placement process, resulting in product deformation and waste of processing costs. In the prior art, the processed aluminum alloy die castings are often installed on the inspection tooling first, and the hole position is inspected by the inspection tooling. If the hole position detection is unqualified, the aluminum alloy die casting is moved to the correction tooling for correction. After correction, the aluminum alloy die casting is installed on the inspection tooling again for inspection until it passes the inspection. In the process of inspection and correction, the aluminum alloy die castings need to be constantly moved back and forth, which increases the labor intensity of inspection and correction, and the operation process is cumbersome, affecting the efficiency of inspection and correction.

The clamping block is symmetrically arranged between the brackets, and the top of the clamping block is threadedly sleeved with the bidirectional screw, and the bottom is slidably connected to the bracket. Rotating the bidirectional screw can drive the clamping blocks to move closer to or away from each other.

The cylindrical or slender aluminum alloy die castings are provided with a plurality of through holes along their length direction. Since the aluminum alloy die castings are relatively soft, during the subsequent heating or processing, the cylindrical or slender aluminum alloy die castings will bend upward or downward, and the positions of the through holes on the deformed aluminum alloy die castings will also change, making the product unqualified. Therefore, it is necessary to inspect and correct the deformed aluminum alloy die castings through the inspection and correction tool of the present application, so that they can be corrected into qualified products to avoid wasting processing costs.

[0031] The aluminum alloy die casting inspection and correction tooling of the present application comprises a workbench 1, a positioning and clamping assembly 2, a plurality of hole position detection assemblies 3 and a correction assembly 4; wherein the positioning and clamping assembly 2 is arranged on the workbench, and is used to position and fix the aluminum alloy die casting to be inspected, the hole position detection assembly 3 is arranged on one side of the positioning and clamping assembly 2, and the number of the hole position detection assemblies 3 corresponds to the number of through holes on the aluminum alloy die casting to be inspected, and each group of hole position detection assemblies 3 comprises a mounting frame 31 and a hole position detection pin 32, wherein the mounting frame 31 corresponds to the position of the through hole on the aluminum alloy die casting, and the mounting frame 3 1 is provided with a reference hole for the hole position detection pin 32 to penetrate, and the hole position detection pin 32 penetrates the reference hole and is inserted into the through hole to detect the hole position; the shape correction component 4 is also arranged on the workbench 1, including an upper shape correction member 41 and a lower shape correction member 42 symmetrically arranged up and down, wherein the upper shape correction member 41 and the lower shape correction member 42 have the same structure, both of which include a shape correction block 411, a telescopic member 412, a column 413 and a cylinder 414, the column 413 is arranged on the workbench 1, the telescopic member 412 is hinged to the column 413, and one end of the telescopic member 412 close to the positioning detection component 2 is fixed to the shape correction block 411 The first end of the upper and second ends of the lower and third ... Correction; when the cylindrical aluminum alloy die-casting is bent downward, the correction block of the upper correction piece 41 is located above the cylindrical aluminum alloy die-casting to play a supporting role, and the correction block 411 is driven by the cylinder 414 of the lower correction piece 42 to hit the deformation position for correction; after the correction is completed, the through-hole position is detected again by the hole position detection pin 32. If multiple hole position detection pins 32 can penetrate the corresponding through holes, it means that the product is qualified. If some hole position detection pins 32 cannot penetrate the through holes, it is necessary to correct the position again until all the hole position detection pins 32 can penetrate the through holes. The workbench 1 of the utility model is provided with a hole position detection component 3 and a correction component 4 at the same time. During the whole detection process, the aluminum alloy die-casting is fixed and kept motionless, which is convenient for detection and correction, avoiding the need to carry multiple groups of aluminum alloy die-castings during detection and correction, improving the convenience of detection and correction, saving time and effort, and improving the efficiency of detection and correction.

[0033] In this embodiment, positioning holes are provided on the aluminum alloy die-casting. Before detection, the positioning holes of the aluminum alloy die-casting are first inserted into the positioning pins 22 to complete the positioning of the aluminum alloy die-casting. The clamping member 23 is fixedly connected to the positioning seat 21 to fix the positioned aluminum alloy die-casting to prevent the aluminum alloy die-casting from shaking during the subsequent shaping process.
