the measuring rod of the dial indicator can drive the dial indicator to change in number when the dial indicator stretches out and draws back, so that depth measurement is carried out; because the measurement precision is difficult to ensure when the dial indicator 1 is operated by hands, other auxiliary fixing structures are needed; the connecting cylinder 3 has the effects that the connecting cylinder can be fixed with the lower end of a dial indicator, and meanwhile, the position stability of a workpiece 9 to be measured in the measurement process is improved by utilizing the clamping groove 4; as shown in fig. 5, the measurement principle is that the upper end of the workpiece 9 to be measured is clamped into the clamping groove 4, the hole position is aligned with the measuring rod part of the dial indicator 1, the measuring rod naturally falls down to pass through the inclined hole touching the workpiece 9 to be measured in the vertical state, and the depth of the inclined hole can be calculated by reading the values of the measuring rod at the two ends of the inclined hole; the first inclined surface 401 is attached to the upper end surface of the workpiece 9 to be measured, so that the stability of the workpiece 9 to be measured can be obviously improved; on one hand, the workpiece 9 to be measured is kept stable by the clamping force between the workpiece 9 and the clamping groove 4, on the other hand, the middle section of the workpiece 9 to be measured can be held by one hand to be fixed in an auxiliary manner in the measuring process, and the workpiece 9 to be measured is placed to slip; meanwhile, the connecting cylinder 3 can adjust the position of the inclined hole to be parallel to the measuring rod by utilizing the included angle between the inclined surface 401 and the telescopic direction of the measuring rod, so that the smooth operation of measuring the inclined hole is ensured.
As shown in fig. 3, the clamping groove 4 is a through groove structure with two ends communicated with each other, so that the workpiece 9 to be measured can be smoothly clamped into the clamping groove 4 from any end in a lateral direction, and the clamping matching efficiency is improved.
As shown in fig. 1 and 2, the bracket 2 further includes a mounting assembly 6; the mounting assembly 6 comprises a cross bar 61 and a turning block 62; the cross rod 61 and the dial indicator 1 are connected with the steering block 62; the steering block 62 is provided with an adjusting hole 621 in a penetrating way; the cross rod 61 is in nested fit with the adjusting hole 621; a fastening screw is further embedded in the steering block 62; the fastening screw is screwed into the adjusting hole 621 to press the cross bar 61 tightly;
by utilizing the steering block 62, the dial indicator 1 can be rotationally adjusted around the cross rod, so that the measuring rod can be recovered and released by utilizing gravity; meanwhile, the position of the dial indicator 1 can be fixed at any rotating position by utilizing the tightness adjustment of the fastening screw, so that the efficient continuity of the operation action is realized.
