Description

Technical Field

[0001] This utility model relates to the field of automotive exhaust system component testing technology, specifically to an electronic measuring tool for the flatness of a beveled pipe. Background Technology

[0002] Beveled pipes are prone to defects during production because the flatness of the bevel side is difficult to guarantee. Currently, traditional inspection tools are used to check the flatness of the bevel side, which is complicated and inefficient. Utility Model Content

[0003] The purpose of this invention is to provide a reasonably structured and reliable electronic measuring tool for the flatness of oblique pipes, solving the problems of complex operation and low efficiency in traditional inspection, and significantly improving the accuracy and efficiency of inspection.

[0004] The technical solution of this utility model is:

[0005] An electronic measuring fixture for the flatness of a beveled pipe includes a base plate. The key technical features are: a positioning seat is provided on the base plate, and a U-shaped positioning groove is provided on the upper surface of the positioning seat. An electromagnet assembly is embedded in the bottom surface of the U-shaped positioning groove. A flatness detection block is provided on the front side of the positioning seat. The flatness detection block has an oblique limiting surface that contacts the beveled opening of the beveled pipe. Four first proximity sensors are embedded within the flatness detection block, facing the oblique limiting surface. The detection ports of the first proximity sensors are arranged on an annular contact trajectory that contacts the beveled opening of the beveled pipe.

[0006] The aforementioned oblique tube flatness electronic measuring fixture has four detection ports of the first proximity sensor arranged in a cross shape on the annular contact trajectory.

[0007] The aforementioned electronic measuring fixture for the flatness of oblique-mouthed pipes has a pressing mechanism on the rear side of the positioning seat. The pressing mechanism includes a support fixed to the base plate and a push-pull mandrel mounted on the support. The center line of the push-pull mandrel coincides with the center line of the oblique-mouthed pipe. The front end of the push-pull mandrel is provided with an expansion pressing plate corresponding to the oblique-mouthed pipe, and the rear end is provided with a pusher.

[0008] The aforementioned electronic measuring fixture for the flatness of oblique pipes has an indicator light button assembly on its base plate that is linked to four first proximity sensors. The indicator light button assembly consists of a green illuminated button that lights up when all four first proximity sensors provide feedback signals, and a red illuminated button that lights up when one or more of the four first proximity sensors do not provide feedback signals. The control switch of the electromagnet assembly is linked to the red illuminated button.

[0009] In the aforementioned electronic measuring fixture for the flatness of oblique-mouthed pipes, the detection distance of the first proximity sensor is 1 mm.

[0010] The aforementioned electronic measuring fixture for the flatness of the oblique tube also includes a second proximity sensor and a third proximity sensor for detecting whether the pressing mechanism is in position. The detection axes of the second proximity sensor and the third proximity sensor are perpendicular to each other to detect the horizontal position of the push-pull spindle of the pressing mechanism in the X and Y directions.

[0011] The beneficial effects of this utility model are:

[0012] 1. In use, after the oblique limiting surface of the flatness detection block contacts the oblique opening of the oblique tube, the flatness is detected by using four first proximity sensors to detect the height difference between four points on the oblique opening. The detection range is within 1mm. When all four first proximity sensors simultaneously provide feedback signals, it indicates that the flatness is qualified, the electromagnet assembly does not activate, and the green indicator button lights up. When one or more of the four first proximity sensors do not provide feedback signals, it indicates that the flatness is unqualified. The electromagnet assembly is energized to generate magnetic attraction to fix the oblique tube, and the red indicator button lights up to remind the operator. Only when the operator presses the red indicator button will the electromagnet assembly be de-energized, allowing the unqualified oblique tube to be removed, facilitating product classification. This utility model can achieve rapid identification of the flatness of the oblique opening side of the oblique tube, with high detection accuracy and efficiency.

[0013] 2. Highly directional measurement. Qualified products can be quickly removed after testing, while unqualified products will be held in place by the electromagnet assembly, making it easy for staff to distinguish between them. Attached Figure Description

[0017] The present invention will be described in detail with reference to the accompanying drawings.

[0018] like Figure 1 , Figure 2As shown, the electronic measuring fixture for the flatness of the oblique-mouthed pipe includes a base plate 1. The base plate 1 is provided with a positioning seat 3, and the upper surface of the positioning seat 3 is provided with a U-shaped positioning groove. An electromagnet assembly 9 is embedded in the bottom surface of the U-shaped positioning groove. A flatness detection block 5 is provided on the front side of the positioning seat 3. The flatness detection block 5 has an oblique limiting surface that contacts the oblique opening of the oblique-mouthed pipe 4. Four first proximity sensors 11 are embedded in the flatness detection block 5 facing the oblique limiting surface. The detection ports of the first proximity sensors 11 are arranged on the annular contact trajectory 14 that contacts the oblique opening of the oblique-mouthed pipe 4.

[0019] In this embodiment, the detection ports of the four first proximity sensors 11 are arranged in a cross shape on the annular contact track 14. The detection distance of the first proximity sensors 11 is 1 mm, that is, the detection range is within 1 mm. The base plate 1 is provided with an indicator light button assembly that is linked to the four first proximity sensors 11. The indicator light button assembly consists of a green illuminated button 7 that lights up when all four first proximity sensors 11 provide feedback signals, and a red illuminated button 6 that lights up when one or more of the four first proximity sensors 11 do not provide feedback signals. The control switch of the electromagnet assembly 9 is linked to the red illuminated button 6.

[0020] A pressing mechanism is provided on the rear side of the positioning seat 3. The pressing mechanism includes a support 13 fixed to the base plate 1 and a pushable spindle 2 mounted on the support 13. The centerline of the pushable spindle 2 coincides with the centerline of the oblique tube 4. The front end of the pushable spindle 2 is provided with an enlarged diameter pressing plate corresponding to the oblique tube 4, and the rear end is provided with a push handle 12. This utility model also includes a second proximity sensor 10 and a third proximity sensor 8 for detecting whether the pressing mechanism is in position. The detection axes of the second proximity sensor 10 and the third proximity sensor 8 are perpendicular to each other to detect the horizontal position of the pushable spindle 2 of the pressing mechanism in the X and Y directions. The base plate 1 is provided with a fixing structure corresponding to the second proximity sensor 10 and the third proximity sensor 8, which is omitted in the figure.

[0021] Operating instructions:

[0022] The beveled tube 4 to be tested is placed in the U-shaped positioning groove of the positioning seat 3, and then the push-pull mandrel 2 is pushed. Under the pressure of the push-pull mandrel 2, the bevel of the tube 4 is brought into close contact with the beveled limiting surface of the flatness detection block 5. At this time, the second proximity sensor 10 and the third proximity sensor 8 are used to detect whether the push-pull mandrel 2 of the pressing mechanism has moved into place. After the second proximity sensor 10 and the third proximity sensor 8 return detection signals, it indicates that the beveled tube 4 has reached the detection position. At this time, the flatness of the bevel of the tube 4 is detected by the four first proximity sensors 11.

[0023] When the four first proximity sensors 11 simultaneously feedback signals, it indicates that the distances between the four first proximity sensors 11 and the bevel are all within 1 mm, the flatness of the bevel is qualified, the electromagnet assembly 9 does not actuate, and the green illuminated button 7 lights up.

[0024] When one or more of the four first proximity sensors 11 do not feedback signals, it indicates that the distance between one or more of the four first proximity sensors 11 and the bevel exceeds 1 mm, the flatness of the bevel is unqualified, the electromagnet assembly 9 is powered on to generate magnetic suction to fix the beveled tube 4, and at the same time the red illuminated button 6 lights up to remind the staff. The staff presses the red illuminated button 6, the electromagnet assembly 9 loses power, and the unqualified beveled tube 4 is removed and placed in the defective product area.

[0025] The measurement method of the present utility model uses the height difference between four points to achieve flatness detection, only determines whether the product is qualified or unqualified, and does not output specific values. It can quickly identify the quality of the product, significantly improve production efficiency, and increase production capacity.

[0026] The above has described the embodiments of the present utility model in detail, but the content described is only the preferred embodiments of the present utility model and cannot be considered as limiting the scope of implementation of the present utility model. All equivalent changes and improvements made within the scope of the creation of the present utility model shall still fall within the scope covered by this patent.
