Description

Technical Field

[0001] The utility model belongs to the technical field of automobile sheet metal parts detection, and specifically relates to an automobile sheet metal parts inspection tool. Background Art

[0002] When inspecting automobile sheet metal parts, it is necessary to install a device and mechanism for positioning the automobile sheet metal parts on the inspection frame, and to position the automobile sheet metal parts for inspection by forming a positioning surface on the inspection frame. However, the device for positioning the automobile sheet metal parts on the inspection frame can only detect the positioning of a single automobile sheet metal part, and cannot realize the positioning and inspection of multiple automobile sheet metal parts by a single inspection frame. However, with the continuous development of the vehicle market, the vehicle model is updated faster and faster, and the number of newly developed automobile parts is increasing. Each new vehicle model requires the production of multiple new inspection frames. However, the cost of developing a separate inspection frame for each automobile sheet metal product for inspection is high, and it is time-consuming and labor-intensive, wasting manpower and material resources. Utility Model Content

[0003] The utility model provides an automobile sheet metal parts inspection tool, which is intended to be combined to form a positioning surface for realizing the positioning of various automobile sheet metal parts.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] like Figures 1 to 6 The illustrated automobile sheet metal inspection fixture has a support block 12 disposed at the upper end of a circular guide column 10, a detection block 11 fixed on the upper part of the support block 12, a through hole 21 for the circular guide column 10 to pass through the lower part of the base 20, and the circular guide column 10 and the through hole 21 form a dynamic fit, the upper end of the through hole 21 is a non-circular shaped hole 22 with a horizontal cross-section of the hole wall, the contour of the vertical circumferential surface of the support block 12 is consistent with the hole shape of the shaped hole 22, the support block 12 can be in a position where the vertical circumferential surface of the support block 12 coincides with the hole wall of the shaped hole 22 and falls to a low position in the shaped hole 22, or when it is lifted to a high position and the vertical circumferential surface of the support block 12 is misaligned with the hole wall of the shaped hole 22, the support block 12 is placed at the upper edge of the shaped hole 22.

[0011] First of all, it should be explained that the automobile sheet metal inspection fixture in this application is generally fixed on a plurality of automobile sheet metal inspection brackets, and the automobile sheet metal is placed on the inspection block 11. The upper top surfaces of the plurality of inspection blocks 11 form a positioning surface to position the automobile sheet metal for inspection.

[0012] In the above scheme, a support block 12 is provided at the upper end of the circular guide column 10, and the detection block 11 is fixed on the upper part of the support block 12. The lower part of the base 20 is provided with a through hole 21 for the circular guide column 10 to pass through, and the circular guide column 10 and the through hole 21 form a dynamic fit. The contour of the vertical circumferential surface of the support block 12 is consistent with the hole shape of the special-shaped hole. By rotating the circular guide column 10 so that the support block 12 is in a position where the vertical circumferential surface of the support block 12 is consistent with the hole wall of the special-shaped hole 22, the support block 12 will fall to the low position in the special-shaped hole 22. At this time, the detection block 11 is placed at the upper edge of the special-shaped hole 22, that is, the avoidance position of the detection block 11 when not detecting. When the circular guide column 10 is pushed upward along the through hole 21 to lift the support block 12 to a high position, and then the circular guide column 10 is rotated so that the vertical circumference of the support block 12 is misaligned with the wall of the special-shaped hole 22, the support block 12 will be placed on the upper edge of the special-shaped hole 22 so that the detection block 11 is in a high position, that is, the detection position of the detection block 11.

[0013] Therefore, in actual production, technicians only need to use the circumferential and axial movements of the circular guide column 10 and the through hole 21 to make the required detection block 11 in a high position and the unnecessary detection block 11 in a low position, and they can use various different combinations of the detection blocks 11 to form positioning surfaces of various automobile sheet metal parts, thereby performing positioning detection on automobile sheet metal parts.

[0014] Furthermore, the base 20 includes a base 20a and a limiting seat 20b on the upper part of the base 20a, the through hole 21 is located in the base 20a, the special-shaped hole 22 is located in the limiting seat 20b, and the through hole 21 and the special-shaped hole 22 are arranged coaxially.

[0015] Furthermore, in order to facilitate the placement of the detection block 11 and the support block 12 at the upper edge of the special-shaped hole 22 perpendicular to the long diameter direction of the special-shaped hole 22, and to facilitate processing, the horizontal cross-sections of the vertical circumferences of the detection block 11 and the support block 12 have consistent rectangular contours, and the contours of the projections of the detection block 11 and the support block 12 on the horizontal plane are cross-shaped.

[0016] Preferably, the special-shaped hole 22 on the limiting seat 20b is a hole with a rectangular hole wall contour, and a groove area with a groove opening facing upward and a groove length intersecting the long diameter direction of the special-shaped hole 22 is provided on the long side of the upper end edge of the special-shaped hole 22.

[0017] In the above scheme, a depression 23 is provided on the long side of the upper edge of the special-shaped hole 22. When the detection block 11 is in a low position, the detection block 11 is placed in the depression 23. When the detection block 11 is in a high position, the support block 12 is placed in the depression 23. The groove walls on both sides of the depression 23 constrain and limit the support block 12, thereby avoiding the support block 12 from rotating randomly at the upper edge of the special-shaped hole 22, and ensuring the support stability of the detection block 11.

[0018] Furthermore, in order to facilitate matching with the detection block 11 and the support block 12 , the groove area formed by the depression 23 is located in the middle of the long diameter direction of the special-shaped hole 22 and the groove length direction is perpendicular to the long diameter direction of the special-shaped hole 22 .

[0019] Furthermore, in order to facilitate the manipulation of the circular guide column 10 to rotate circumferentially or move axially along the through hole 21 , a ball head 13 is connected to the lower end of the circular guide column 10 .

[0020] The preferred round guide column 10 is provided with a spring 30 on the column body below the base 20a, the upper end of the spring 30 abuts against the lower bottom surface of the base 20a, and the lower end of the spring 30 abuts against the ball head 13. When the detection block 11 is in a high position, the spring 30 is in a compressed state, and the elastic force provided by the spring 30 makes the support block 12 fit tightly with the bottom of the groove of the low concave portion 23, thereby ensuring the stability of the detection block 11.
