[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] The excavator boom is the part that connects the boom to the bucket. Together with the boom, it bears the force of excavation. During the assembly and welding process of the excavator boom, the coordination between the rear side plate and the rear curved plate affects the assembly gap and welding quality, which in turn affects the service life of the product. The blanking quality of the side plate and the forming quality of the rear curved plate affect whether the rear side plate and the rear curved plate can be assembled and welded smoothly. The existing method is to use a tape measure to check and measure against the part drawing. For curved structures, when there are no relevant inspection positioning points, it is difficult to inspect the curve line type, arc size and angle, and the inspection accuracy is not high. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an inspection template for the rear side plate and rear bent plate of an excavator boom, which can improve inspection efficiency and accuracy by replacing tape measure measurement with inspection template measurement, and avoid rework and waiting caused by inaccurate dimensional accuracy during actual assembly due to inaccurate inspection.

[0007] Furthermore, it also includes a cross plate, which divides the conformable frame into four parts to form weight-reducing holes.

[0008] Furthermore, the positioning plate is a right-angled trapezoid.

[0009] Furthermore, the angle between the lower bottom and the waist of the positioning plate and the second arc-shaped edge are connected to form a first positioning point.

[0010] Furthermore, the right-angle waist of the positioning plate is perpendicular to the waist of the conformal frame to form a second positioning point.

[0011] Furthermore, the cross plate is cut integrally with the conformal frame.

[0012] Furthermore, the cross plate is used to strengthen the strength of the conformal frame.

[0013] Furthermore, the cross bar of the cross plate is connected to the bending point of the first arc-shaped side of the conformable frame, and the vertical bar of the cross plate is connected to the position below the waist to which the positioning plate of the conformable frame is connected.

[0014] Furthermore, the thickness of the conformal frame and the cross plate are consistent.

[0015] Furthermore, the thickness of the inspection sample body is 5 mm.

[0016] The beneficial effects of one or more of the above technical solutions are:

[0017] The inspection template disclosed in the present invention is clamped on the top of the rear bending plate by a positioning plate, the lower part of the inspection template is aligned with the bottom of the rear bending plate, and the first curved edge is used to measure the size of the bending curvature of the rear bending plate.

[0023] As introduced in the background technology, the existing method is usually to use a tape measure to check and measure against the part drawing. For curved structures, when there are no relevant inspection positioning points, it is difficult to inspect the curve line type, arc size and angle, and the inspection accuracy is not high. The rear side panel will have dimensional deviation and deformation due to the influence of cutting accuracy and heat, and the rear bent panel will also have deviation and deformation due to the influence of mold, bending force, angle and transportation. The rear part of the rear side panel and the rear bent panel are both curved structures, and conventional dimensional inspection is difficult and has low accuracy.

[0024] In order to solve the above technical problems, the utility model proposes an inspection template for the rear side plate and rear bent plate of an excavator boom. Measurement with the inspection template of the utility model replaces measurement with a tape measure, thereby improving inspection efficiency and inspection accuracy, and avoiding rework and waiting caused by inaccurate inspection and inaccurate dimensional accuracy during actual assembly.

[0025] like Figure 1-Figure 3 As shown, one embodiment of the utility model records an inspection template for the rear side plate and rear bend plate of an excavator boom, including: an inspection template body, the inspection template body includes a conformal frame and a cross plate 4, the conformal frame is a trapezoidal plate cut by laser from a 5 mm thick steel plate, which ensures the contour accuracy of the template and reduces the deformation of the template cutting. Similarly, the cross plate 4 is also cut by laser from a 5 mm thick steel plate. The cross plate 4 is cut integrally with the conformal frame; it can enhance the strength of the template and facilitate the removal of the template.

[0026] A positioning plate 3 is provided on one waist of the conformable frame, and the positioning plate 3 is a right-angled trapezoid; the waist of the conformable frame with the positioning plate 3 faces upward, and the other waist of the conformable frame faces downward and is parallel to the horizontal plane, so that the conformable frame can be tilted laterally; the upper bottom of the conformable frame is a first arc-shaped edge 1 bent outward, and the angle between the lower bottom of the conformable frame and the waist with the positioning plate 3 forms a second arc-shaped edge 2 bent inward.

[0027] The angle between the lower bottom and waist of the positioning plate 3 and the second arc-shaped edge 2 are connected to form a first positioning point 5; the right-angle waist of the positioning plate 3 is perpendicular to the waist of the conformal frame to form a second positioning point 6; the cross plate 4 divides the conformal frame into four parts to form weight-reducing holes, which can reduce the weight of the sample and reduce the work intensity.

[0028] The first arcuate edge 1 and the second arcuate edge 2 can be used to detect the dimensional accuracy of the bent portion of the rear side plate and the rear bent plate by a light transmission method or a feeler gauge, thereby preventing rework and waiting caused by inaccurate dimensional accuracy during actual assembly.

[0029] Working principle:

[0030] like Figure 2As shown, when inspecting the rear side panel, the waist of the conformal frame parallel to the horizontal plane is aligned with the bottom edge of the rear side panel, the first positioning point 5 is aligned with the top of the rear side panel, the second arc edge 2 and the first arc edge 1 are aligned with the curved part of the rear side panel, and a ruler is used to directly measure the deviation position size to measure the size of the bending curvature of the rear side panel.

[0031] like Figure 3 As shown, when inspecting the rear bent plate, put the conformable frame into the rear bent plate, align the waist of the conformable frame parallel to the horizontal plane with the bottom edge of the rear bent plate, clamp the upper end of the rear bent plate with the second positioning point 6 formed by the positioning plate 3 and the waist of the conformable frame, align the first arc edge 1 with the bent part of the rear bent plate, and use the light transmission method or feeler gauge to measure the size of the bending curvature of the rear side plate to check the overlap of the rear bent plate and the sample.

[0032] Although the above describes the specific implementation methods of the present disclosure in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present disclosure. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present disclosure, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present disclosure.
