[0002] On some products with upper and lower split structures, the upper body needs to be processed with a light hole for the connection hole and a groove, and the lower body has a threaded hole. When the workshop marks the assembly holes of the upper shell, it usually first marks the position of the assembly light hole on the middle surface of the upper shell according to the situation of the blank, then uses the drilling machine to process the holes of the upper body, and then uses the holes of the upper body to drill the assembly screw holes on the middle surface of the lower body.

[0003] Often when marking the upper shell, due to the irregularity of the blank, it is impossible to check the situation after drilling in advance. This often results in the blank being deviated too much when marking after drilling and drilling, resulting in unforeseen quality problems such as too thin wall thickness, pin hole obstruction, exposed marking hole, etc., and this quality problem has already occurred and cannot be repaired. Generally, it has to be left to the user's product, affecting the appearance quality and damaging the user's image of the company's quality. Utility Model Content

[0011] The utility model provides an assembled hole anti-scratch pre-inspection tool. By setting a freely adjustable lower positioning plate, it can be freely adjusted according to the thickness of the material to be inspected. The tip of the upper ejector pin is aligned with the punching point position drawn on the center dividing surface. Then, the lower positioning plate is moved up and down to check the scratching condition of the irregular blank below. If there may be quality problems with the size of the scratches in the future, the position of the punching point on the center dividing surface can be appropriately corrected, so as to ensure that our processing meets the design requirements at one time and avoid some quality problems that may occur later in advance, so as to ensure quality and improve efficiency.

[0019] See also Figures 1 to 5 As shown, according to an embodiment of the utility model, a pre-inspection tool for anti-scratch of an assembled hole is provided, comprising a support rod 1, an upper positioning plate 2 is connected along its radial direction at one end of the support rod 1, a lower positioning plate 3 is also sleeved on the support rod 1, the lower positioning plate 3 can slide along the axial direction of the support rod 1, and a first through hole is provided along its radial direction at one end of the upper positioning plate 2 away from the support rod 1, an upper ejector 4 is slidably arranged in the first through hole, and a lower ejector 5 is fixedly arranged on the lower positioning plate 3, and the axis of the upper ejector 4 is collinear with the axis of the lower ejector 5. By setting a freely adjustable lower positioning plate, it can be freely adjusted according to the thickness of the material to be inspected, and the tip of the upper ejector 4 is aligned with the punching point position drawn on the center dividing surface, and then the lower positioning plate 3 is moved up and down to check the scratching of the irregular blank below. If there may be quality problems with the size of the scratching in the future, the position of the sample punching point on the center dividing surface can be appropriately corrected, so as to ensure that our processing meets the design requirements at one time, and avoid some quality problems that may occur later in advance, so as to ensure quality and improve efficiency.

[0020] In a specific embodiment, along the axial direction of the support rod 1, the outer wall of the support rod 1 has a slide groove, and one end of the lower positioning plate 3 sleeved with the support rod 1 has a first threaded hole 31, and a screw passes through the first threaded hole 31 and is adapted to the slide groove, so that the lower positioning plate 3 can slide along the axial direction of the support rod 1. Through the cooperation of the screw and the slide groove, the lower positioning plate 3 can be ensured to move axially along the support rod 1, and the lower positioning plate 3 can be prevented from rotating, so that the upper and lower ejector pins are always kept on the same axis, thereby improving the positioning accuracy.

[0021] In a specific embodiment, along the axial direction of the upper ejector pin 4, the outer wall of the upper ejector pin 4 has a groove, the upper positioning plate has a second threaded hole, and a screw is passed through the second threaded hole and adapted to the groove, so that the upper ejector pin 4 can slide along the groove. The groove and the screw are matched to allow the upper ejector pin 4 to slide in the groove without leaving the groove, thereby achieving the positioning of the upper ejector pin. In addition, the structures of the materials to be tested are different, and the surface to be tested may be irregular in shape. The sliding upper ejector pin can adapt to contact surfaces of more shapes.

[0022] In a specific embodiment, the upper positioning plate 2 is further provided with a magnet installation hole 22 for installing a magnet. The addition of the magnet arrangement enables the upper positioning plate 2 to fit more closely and stably with the material to be inspected, thereby improving the detection accuracy.
