Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described below are merely illustrative of this utility model. Key terms used in these descriptions, including "contour mimicking," "contour mimicking surface," "single row," and "double row," are simply customary names and are used for ease of description and simplification; therefore, they should not be construed as limitations on this utility model.

[0026] Since the rear support frame of two-wheeled electric vehicles has been changed from metal to plastic, its strength may be weakened. Using metal inserts can increase its strength. For example... Figure 1 As shown, the rear support frame P of the two-wheeled electric vehicle includes a backrest frame P1 and a seat cushion frame P2, which are injection molded as one piece. The backrest frame P1 bears the most concentrated force. Figure 2 The metal insert Q shown is embedded in the back frame P1 through injection molding to increase strength. The metal insert Q has a folded edge Q1 to enhance strength and a through hole Q2 to facilitate the secure injection molding of the embedded metal insert Q. This utility model relates to a testing fixture for metal inserts on the rear support frame of a two-wheeled electric vehicle. It is used to inspect the surface shape of the metal inserts on the rear support frame of a two-wheeled electric vehicle, enabling the use of metal inserts with intact surface shapes for injection molding, ensuring product quality. It includes an upper body S, a lower body T, guide posts S3, guide sleeves T3, a single-row positioning pin S5, a double-row positioning pin S9, a single-row positioning pin T10, a double-row positioning pin T9, a single-row support pin T6, a double-row support pin T5, a headless screw S7, and a headless screw T7, as shown. Figure 3-7As shown, the lower end face of the upper body S is provided with a step T4, the middle section of which is a contour surface S2, which is contoured to conform to the surface shape of the corresponding metal insert Q. The two ends of its lower end face are positioning surfaces S1. The contour surface S2 and the positioning surface S1 are smoothly connected. The guide post S3 is fixedly connected to the two positioning surfaces S1 of the upper body S by a headless screw S7. The guide post S3 is provided with a concave ring S4 on its outer periphery to reduce the contact area. The upper body S is also provided with screw holes S8 and mounting holes S6 for installing various pins. The single-row positioning pin S5 and the double-row positioning pin S9 are headless stepped screws with a nominal diameter of 4-6mm. They are fixedly screwed into the screw hole S8 through the mounting hole S6 using the step of the headless stepped screw, and protrude 1.5-3.5mm from the lower end face of the upper body S. The single-row positioning pin S5 is arranged separately, while the double-row positioning pin S9 is arranged in pairs side by side, both located at both ends of the contour surface S2 on the lower end face of the upper body S. The single-row positioning pin S5 and the double-row positioning pin S9 form a stable three-point positioning.

[0027] See Figure 8-9As shown, the middle section of the upper surface of the lower body T is a contour surface T2, which is contoured to conform to the surface shape of the corresponding metal insert Q. The two ends of its upper surface are positioning surfaces T1. The contour surface T2 and the positioning surface T1 are smoothly connected. The upper surface of the lower body T is provided with a step T4. The guide sleeve T3 corresponds to the guide post S3 on the upper body S. It is fixed to the two positioning surfaces T1 of the lower body T by tightening the headless screws T7. The lower body T is also provided with screw holes T11 and mounting holes T8 for installing various pins. The single-row positioning pins T10 and double-row positioning pins T9 are also headless stepped screws with a nominal diameter of 4-6mm. They correspond to the single-row positioning pins S5 and double-row positioning pins S9 of the upper body S. They are fixedly screwed into the screw holes T11 through mounting holes T8 and protrude 1.5-3.5mm from the upper end face of the lower body T. The single-row positioning pins T10 are arranged separately, while the double-row positioning pins T9 are arranged in pairs side by side, both located at both ends of the contour surface T2 on the upper end face of the lower body T. A stable three-point positioning is formed by the single-row positioning pins T10 and double-row positioning pins T9. The single-row support pins T6 and double-row support pins T5 also use headless stepped screws with a nominal diameter of 4-6mm. They are fixedly screwed into screw hole T11 via mounting hole T8, utilizing the step of the headless stepped screw, and protrude 1.5-3.5mm from the upper end face of the lower body T. The end faces of the single-row support pins T6 and double-row support pins T5 protruding from the upper end face of the lower body T are contoured to match the surface shape of the corresponding metal insert Q. The location of the single-row support pin T6 is separately arranged. The double-row support pins T5 are arranged in pairs side by side, both located in the middle section of the contour surface T2 on the upper end face of the lower body T. The guide post S3 of the upper body S corresponds to the guide sleeve T3 in which the lower body T is installed. They are limited by the positioning surface S1 of the upper body S and the positioning surface T1 of the lower body T. The single-row positioning pin S5 and the double-row positioning pin S9 of the upper body S abut against the single-row positioning pin T10 and the double-row positioning pin T9 of the lower body T, forming a gap K.

[0028] In use, the metal insert Q is first placed in the mounting hole corresponding to the lower body T's contour surface T2. It is positioned by the single-row positioning pins T10 and double-row positioning pins T9 of the lower body T. The folded edge Q1 of the metal insert Q is positioned on the step 4 of the lower body T. Then, the guide post S3 of the upper body S is aligned with the guide sleeve T3 of the lower body T. The upper body S's positioning surface S1 and the lower body T's positioning surface T1 limit their movement. The single-row positioning pins of the upper body S... S5 and double-row positioning pin S9 correspond to the single-row positioning pin T10 and double-row positioning pin T9 of the lower body T, ensuring that there is no movement in any direction. If the surface of the metal insert Q is intact, the single-row support pin T6 and double-row support pin T5 of the lower body T can fit well with the metal insert Q, and the gap K is normal. Otherwise, by checking the misfit between the single-row support pin T6 and double-row support pin T5 and the metal insert Q, the deformed part of the metal insert Q can be identified, and it can be removed and reshaped.

[0029] The above description is only a general embodiment of this utility model. For those skilled in the art, there are various other embodiments with modifications and variations, which will not be elaborated here. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model are included within the protection scope claimed by this utility model.
