Description

Accurate gauge for drilling depth of automobile front wall plate Technical Field The utility model relates to the technical field of industrial measurement gauge, in particular to an accurate gauge for drilling depth of an automobile front coaming. Background The drilling depth detection of the automobile dash panel is an important link for ensuring drilling quality in the automobile manufacturing process, and because drilling can have certain taper or non-uniformity, in order to ensure the accuracy of a measurement result, measurement is carried out under stable environmental conditions, and the influence of factors such as temperature, humidity, vibration and the like on the measurement result is avoided. For example, the change of temperature can lead to the expend with heat and contract with cold of work piece and measuring tool to influence measurement accuracy, be provided with the drilling of multiple different degree of depth on the current dash board, current degree of depth measuring tool adopts the depth chi on the slide caliper to measure mostly, needs the hand to hold when the depth chi measures, rocks easily in the use, is difficult for reading the data, and it is not convenient enough to use, and measurement accuracy is not enough. The Chinese patent with the publication number of CN212674029U discloses an accurate drilling depth gauge for an automobile dash panel, which comprises a main board, a rotating ball, a measuring scale and a poking block, wherein a clamping groove is formed in the middle of the main board, and the rotating ball is movably clamped in the clamping groove. According to the utility model, the clamping groove is formed in the main plate, the rotating ball is movably clamped in the clamping groove, the freely movable measuring scale is clamped in the rotating ball, the measuring scale is arranged on the measuring scale, the measuring scale can be matched with the comparison scale on the comparison block for reading, the reading is more accurate, meanwhile, the comparison block is provided with a single-side opening, the reading of the measuring scale is convenient, the rotatable rotating ball can be adjusted in verticality in a certain range, the rotating ball is relatively parallel to a measuring drilling hole, the adsorption blocks on two sides can be used for stably placing the device, the phenomenon of manual placement and shaking is avoided, and the measuring device is good in use effect and accurate in measurement. But above-mentioned patent, when using, only can adjust the straightness that hangs down of dipperstick through the ball of rotation, but can not guarantee that the fixed subassembly of both sides can be symmetrical completely, can't guarantee that the dipperstick is in the central point of measuring the hole promptly, when the inner chamber bottom of measuring the hole is the cambered surface, can lead to measuring result inaccurate, the shape of the dash board of car is plane and cambered surface to combine together simultaneously, when measuring the hole on the cambered surface, the fixed subassembly of both sides is fixed unstable through the sucking disc, and the both sides highly is different, it is comparatively troublesome to adjust the straightness that hangs down of dipperstick. Disclosure of utility model The utility model aims to provide an accurate gauge for drilling depth of an automobile dash panel, which aims to solve the problems that in the background technology, the verticality of a measuring ruler can be adjusted only through a rotating ball, but the fixed assemblies at two sides cannot be guaranteed to be completely symmetrical, namely the measuring ruler cannot be guaranteed to be positioned at the center of a hole to be measured, when the bottom of an inner cavity of the hole to be measured is an arc surface, the measuring result is inaccurate, meanwhile, the shape of the dash panel of the automobile is the combination of a plane and the arc surface, when holes on the arc surface are measured, the fixed assemblies at two sides are unstable through sucking discs, the heights of the two sides are different, and the verticality of the measuring ruler is troublesome to adjust. In order to achieve the aim, the technical scheme is that the accurate drilling depth gauge for the automobile dash panel comprises a connecting plate, an adjusting piece, a measuring ruler and a holding rod, wherein the adjusting piece is located on the inner side of the connecting plate, the measuring ruler is located on the inner side of the adjusting piece, the holding rod is fixedly connected to two sides of the outer side wall of the adjusting piece, sliding rails are fixedly connected to four corners of the bottom of the connecting plate, sliding pieces are connected to the connecting ends of the sliding rails in a sliding mode, connecting rods are fixedly connected to the inner ends of the sliding pieces, clamping pieces are fixedly connected to the tail e
