Description

Technical Field

[0001] The present application relates to the technical field of sheet metal inspection, and in particular to an inspection tool for small sheet metal parts. Background Art

[0002] like Figure 1 As shown, small sheet metal parts refer to parts or products made by processing metal sheets (usually with a thickness of less than 6 mm). The metal sheets are bent, polished and other processes to form small sheet metal parts. The small sheet metal parts include a sheet metal body 101, a bent portion 102, an end 103, a first hole 104, a second hole 105 and a protrusion 106. The bent portion 102 is designed to be perpendicular to the sheet metal body 101, and the length design requirement of the end 103 must also be within a reasonable range. However, small sheet metal parts may be easily deformed during the processing due to factors such as raw materials, environment and operation. Therefore, after processing, the bending angle of the bent portion 102 of the sheet metal and the length of the end 103 need to be inspected. Traditional sheet metal inspection uses a detection ruler in combination with naked eye observation. However, the method of naked eye observation has low efficiency in detecting the shape of sheet metal parts. Utility Model Content

[0017] Preferably, the detection block is provided with a detection column for detecting the second hole position of the sheet metal part, and the detection column is plug-fitted with the second hole position.

[0018] By adopting the above technical solution, the detection column cooperates with the second hole on the sheet metal part, and the cooperation between the second hole and the detection column is observed to determine whether the second hole meets the standard.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1 -Attached Figure 4 This application is described in further detail.

[0031] The embodiment of the present application discloses a checking fixture for small sheet metal parts.

[0032] Reference Figure 2 and Figure 3 A small sheet metal inspection tool comprises a base plate 2 and a detection block 3 vertically arranged on the base plate 2. A first positioning pin 201 is vertically arranged on the base plate 2, and a positioning hole 301 matching the first positioning pin 201 is provided on the detection block 3. The detection block 3 is accurately set on the base plate 2 through the first positioning pin 201. The detection block 3 is also rotatably connected to the detection block 3 with a fixing bolt 302, and the fixing bolt 302 is threadedly connected to the base plate 2. The detection block 3 is detachably connected to the base plate 2 through the fixing bolt 302. Different detection blocks 3 can be replaced according to different sheet metal parts, thereby adapting to the detection needs of sheet metal parts of different sizes, thereby improving the versatility of the inspection tool.

[0033] Reference Figure 3 and Figure 4 A second positioning pin 202 for positioning the sheet metal is provided on the base plate 2, and a plug hole 203 that cooperates with the second positioning pin 202 is also provided on the base plate 2. The second positioning pin 202 and the plug hole 203 form a plug-in fit. The detection block 3 is also provided with a detection column 303 for detecting the second hole position 105. The detection column 303 is horizontally arranged on the detection block 3 and vertically arranged on the detection block 3. Before detection, the sheet metal is first installed, the second positioning pin 202 is removed, and the second hole position 105 is aligned with the detection column 303 for installation. After the first hole position 104 is aligned with the plug hole 203, the second positioning pin 202 is installed to fix the sheet metal.

[0034] Reference Figure 1 and Figure 4 The way the detection column 303 detects the second hole 105 is that if the detection column 303 cannot penetrate the second hole 105, the second hole 105 is too small and unqualified; if the detection column 303 can penetrate the second hole 105, observe the size of the gap between the second hole 105 and the detection column 303. If the gap is too large, it is also unqualified.

[0035] Reference Figure 1 and Figure 4 , a first detection rod 4 for detecting the bending angle of the sheet metal is also horizontally arranged on the detection block 3. The first detection rod 4 is perpendicular to the detection block 3 and is arranged through the detection block 3. The first detection rod 4 forms a sliding fit with the detection block 3. A second detection rod 5 for detecting the size of the end 103 of the sheet metal is also horizontally arranged on the detection block 3. The second detection rod 5 is perpendicular to the detection block 3 and is arranged through the detection block 3. The second detection rod 5 forms a sliding fit with the detection block 3. A first tightening bolt 6 and a second tightening bolt 7 are also threadedly connected to the detection block 3. The first tightening bolt 6 forms an abutment fit with the first detection rod 4, and the second tightening bolt 7 forms an abutment fit with the second detection rod 5.

[0036] Reference Figure 1 and Figure 4After the sheet metal is installed, adjust the position of the first detection rod 4 so that the end of the first detection block 3 close to the sheet metal is perpendicular to the sheet metal body 101 and forms an abutment fit, then tighten the first tightening bolt 6, observe the abutment between the bent portion 102 of the sheet metal and the side of the first detection block 3 to determine whether the bending angle of the bent portion 102 meets the standard.

[0037] Reference Figure 1 and Figure 4 , the second detection rod 5 is used to detect the size of the end 103 of the sheet metal. The position of the second detection rod 5 is set according to the size of the end 103 of the sheet metal. The end 103 is located between the first detection rod 4 and the second detection rod 5. Before the sheet metal is installed, the position of the second detection rod 5 is adjusted so that the second detection rod 5 is completely away from the side of the detection block 3 close to the sheet metal. After the sheet metal is installed, the second detection rod 5 is extended to the side close to the sheet metal. If the second detection rod 5 cannot be fully extended, or the gap between the end 103 and the second detection rod 5 after extension is too large, it is unqualified. After the position of the second detection rod 5 is determined, the second tightening bolt 7 is tightened to ensure the accuracy and repeatability of the detection. It can be judged whether the size of the end 103 of the measured sheet metal meets the standard.

[0038] Reference Figure 1 and Figure 3 The bottom plate 2 is provided with a groove 8 that matches the protrusion 106 of the sheet metal part. The protrusion 106 and the groove 8 form an embedded fit. During the inspection process, the protrusion 106 of the sheet metal part is embedded in the groove 8, which can make the position of the sheet metal part on the bottom plate 2 more stable. If the protrusion 106 of the sheet metal part cannot be embedded in the groove 8 or the gap after embedding is too large, it will fail the test.

[0039] The implementation principle of the embodiment of the present application is: use the second positioning pin 202 to install the sheet metal on the inspection fixture, adjust the first detection rod 4 so that it abuts against the sheet metal body 101 and then fix it, observe the abutment between the bent portion 102 and the side of the first detection rod 4, and judge whether the bending angle is qualified, then extend the second detection rod 5, observe the extension situation to judge whether the size of the end 103 is qualified.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
