[0002] Current automotive parts products often have some CNC machined parts with complex shapes, such as Figure 1 A CNC welded aluminum profile part is shown, which has a bottom surface, a flange, side wings and a tail wing. A first threaded hole and a second threaded hole are arranged on the bottom surface, and the two threaded holes have reference position requirements. The flange has a plane and a curved surface connected to the plane, the plane has a circular hole extending in a direction perpendicular to the plane, and the curved surface has symmetrically arranged two cutouts with surface profile requirements.

[0003] In the prior art, for the size control, position and contour detection of the above-mentioned complex-shaped CNC welded parts, three-coordinate measuring machines are usually used to perform batch sampling to ensure the reliability of various indicators. The three-coordinate measuring machine is expensive, takes a long time to detect, and has low detection efficiency for small planes, so it is difficult to apply it to the mass production process of products.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A quick detection contour gauge for aluminum profiles comprises a base, on which a plurality of profiling components are mounted, each profiling component forms a frame on the base, and the internal shape of the frame formed by each profiling component profiles the external contour of the aluminum profile to be measured, the aluminum profile to be measured is accommodated inside the frame, wherein some of the profiling components are respectively mounted with reference positioning blocks on the inner wall of the frame for reference positioning of the aluminum profile to be measured; and further comprises a go-no-go detection plug gauge, which is used to detect the external contour of the aluminum profile to be measured in the frame.

[0007] Furthermore, the base is equipped with a plurality of calibration origin references as zero references, and the zero reference calibration of the entire gauge is achieved through the plurality of calibration origin references.

[0008] Furthermore, a plurality of reference positioning blocks are used to form a three-point reference positioning for the aluminum profile to be measured.

[0009] Furthermore, positioning pins are movably mounted on the base at positions corresponding to several of the profiling components. The positioning pins pass through the corresponding profiling components and extend into the frame, and the aluminum profile to be tested is positioned by the positioning pins.

[0010] In the utility model, the aluminum profile to be tested is placed in the frame surrounded by the profiling component, and the reference positioning block cooperates with the positioning pin to perform reference positioning on the aluminum profile to be tested, and the through-and-stop detection plug gauge is used to move in the frame to detect the outer contour of the aluminum profile to be tested. Before the test, the zero reference calibration of the entire inspection fixture is realized by calibrating the origin reference.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] Compared with the three-dimensional inspection machine for detecting surface contour, this inspection fixture sets a contour component frame that matches the shape of the aluminum profile to be inspected, and cooperates with the go-no-go inspection plug gauge to check the outer contour of the aluminum profile to be inspected. It can quickly detect whether the surface contour of the aluminum profile to be inspected is qualified, and can meet the quality inspection requirements of fast, batch and accurate inspection of the contour of the aluminum profile to be inspected.

[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 2 , Figure 3 As shown, this embodiment discloses a quick contour detection gauge for aluminum profiles, including a square and horizontally placed base 1, a plurality of feet 8 are fixed to the bottom of the base 1, a handle 7 is fixedly connected to one side of the base 1, and a plurality of contour-matching components 3 are arranged on the top surface of the base 1. This embodiment is described by taking four contour-matching components 3 as an example.

[0018] Each profiling component 3 is fixedly mounted on the base 1 by bolts and nuts, and four profiling components 3 are surrounded by a frame on the base 1, and the four profiling components 3 form an internal shape of the frame on the inner wall of the frame, and the internal shape of the frame is designed to imitate the shape of the outer contour of the aluminum profile to be tested according to the design drawing of the aluminum profile to be tested, and the aluminum profile to be tested is accommodated in the frame, and the gap between the outer walls around the aluminum profile to be tested and the corresponding frame walls inside the frame is designed to be 1 mm.

[0019] The back side profiling component 3 is respectively installed with reference positioning blocks 4 on the inner wall of the frame (i.e., the back side frame wall of the frame) and the right side profiling component is respectively installed with reference positioning blocks 4 on the inner wall of the frame (i.e., the right side frame edge of the frame). Specifically, the reference positioning block 4 is connected with a cylindrical pin and a conical screw on one side facing the inner wall of the corresponding profiling component 3, the cylindrical pin of the reference positioning block 4 is inserted into the positioning pin hole of the inner wall of the corresponding profiling component 3, and the conical screw of the reference positioning block 4 is locked by a nut after passing through the through hole of the corresponding profiling component 3, thereby fixing the reference positioning block 4 on the inner wall of the corresponding profiling component 3.

[0020] In this embodiment, a reference positioning block 4 is installed on the inner wall of the rear side profiling component 3 as the B-side reference, and two horizontally arranged reference positioning blocks 4 are installed on the inner wall of the right side profiling component as the A-side reference, thereby forming a three-point reference positioning for the aluminum alloy profile to be tested.

[0021] In this embodiment, the opposite side of the reference positioning block on each side is also provided with a positioning pin 6, which is used to cooperate with the reference positioning block to realize the positioning of the aluminum alloy profile to be measured. Specifically, the front position of the profiling component on the front side and the left position of the direction component on the left side of the base 1 are respectively fixed with mounting seats, and the mounting seats are respectively installed with guide channels, and the guiding direction of the guide channel is horizontally perpendicular to the corresponding side profiling component 3. The positioning pin 6 is installed in the guide channel, and the specific positioning pin 6 includes a cylindrical pin and a truncated cone tail at one end of the cylindrical pin, and a conical head at the other end of the cylindrical pin. The conical head of the positioning pin 6 extends into the frame along a horizontal direction perpendicular to the corresponding profiling component. Thus, the positioning pin on the left side cooperates with the two reference positioning blocks on the right side, and the positioning pin on the front side cooperates with a reference positioning block on the rear side to realize the positioning of the aluminum alloy profile to be measured.

[0022] In this embodiment, calibration origin references 2 are respectively installed at the four corners of the base 1.

The four calibration origin references 2 serve as zero position references, where the reference value is that the aluminum alloy profile to be tested is installed in the frame and the profiling component 3 is installed on the base, and the three-dimensional coordinate system is used to detect the zero point deviation of the calibration of the entire inspection fixture through the four calibration origin references.

[0023] This embodiment also includes a through-and-no-go detection plug gauge 5. The through-and-no-go detection plug gauge includes a through gauge, a stop gauge and a connecting rod, the through gauge is located at one end of the connecting rod, and the stop gauge is located at the other end of the connecting rod. When working, the aluminum alloy profile is placed in the profiling component 3, and the profile reference surface is aligned with the A reference (two blocks) and the B reference (1 block) in the reference positioning block 4 according to the drawing or the reference surface required by the customer. The positioning pin 6 on the left side and the two reference positioning blocks 4 (A reference) on the right side are matched for positioning, and the positioning pin 6 on the front side and a reference positioning block 4 (B reference) on the rear side are matched for positioning. The through gauge detected by the through-and-no-go gauge 5 is placed in the gap between the profiling component and the aluminum alloy profile, and can move in the frame along the contour of the aluminum alloy profile to be tested. The stop gauge performs the same operation, the through gauge can pass, and the stop gauge can stop, thereby realizing the detection of the entire outer contour of the aluminum alloy profile to be tested.
