Description

Technical Field

[0001] This utility model relates to electronic digital display indicators in geometric measurement instruments, specifically an electronic digital display indicator moving grid base and measuring rod mounting structure. Background Technology

[0002] Electronic digital display dial indicators are a widely used type of general-purpose measuring instrument for geometric measurement. In practical applications, the gap between the moving and fixed gratings, as well as the parallelism between the moving and fixed gratings during movement, have a significant impact on the measurement accuracy of electronic digital display dial indicators.

[0003] In the prior art, the fixed grid is set in the digital display motherboard of the electronic digital display, while the moving grid is installed on the moving grid seat of the measuring rod. When measuring the workpiece, the moving grid moves up and down with the measuring rod.

[0004] For example, in the technical solution of the "High-precision electronic digital display meter with large range and small shape" authorized announcement number CN204154318U, the measuring rod passes through the moving grid seat. The moving grid seat is screwed with two screws, one upper and one lower, into the measuring rod to fasten the moving grid seat to the measuring rod. The parallelism requirement between the moving grid seat and the measuring rod depends on the accuracy of the through hole on the moving grid seat, which is difficult to process. Utility Model Content

[0005] The purpose of this invention is to propose an easy-to-manufacture and adjust electronic digital display indicator mounting structure for the moving grid and measuring rod.

[0006] This utility model relates to an electronic digital display indicator moving grid base and measuring rod mounting structure. Its technical solution includes a moving grid base and a measuring rod, the difference being:

[0007] 1. The moving grid seat includes a grid plate and a grid seat disposed at the front and rear inside the watch case.

[0008] 2. The grid seat has upward and downward rod holes, and the radius of the rod holes is greater than the distance from the center of the holes to the front end face of the grid seat, thus forming a slot on the grid seat.

[0009] 3. The measuring rod passes through the rod hole and protrudes from the groove.

[0010] 4. The grid plate is attached to the exposed measuring rod so that there is a gap between the grid plate and the grid seat. The screws symmetrically arranged on the left and right between the grid seat and the grid plate fasten the grid plate, the grid seat and the measuring rod together.

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

[0012] 1. In the installation structure of the moving grid seat and measuring rod of the electronic digital display indicator of this utility model, the moving grid seat is designed as a split structure, so that the grid plate directly rests on the measuring rod, ensuring the parallelism and dimensional requirements of the center line of the grid plate and the measuring rod, and reducing the parallelism error between the grid plate and the measuring rod.

[0013] 2. In the installation structure of this utility model, the grid plate directly rests on the measuring rod to maintain the gap between the grid plate and the grid seat, so as to ensure that the connection between the grid plate and the measuring rod is flexible and reliable, and to facilitate the adjustment of the parallelism between the grid plate and the fixed grid. By changing the thickness of the grid plate, the gap between the grid plate and the fixed grid can be easily adjusted, thereby ensuring the gap between the moving and fixed grids.

[0014] 3. In the installation structure of this utility model, when the left and right screws are tightened, the measuring rod can be reliably connected to the grid seat by means of the slight deformation of the slotted rod hole. Attached Figure Description

[0021] The technical solution of this utility model will be further described below with reference to the embodiments shown in the accompanying drawings.

[0022] The present invention relates to an electronic digital display indicator moving grid seat and measuring rod mounting structure, including a moving grid seat disposed inside the case 5, the moving grid seat being mounted on the measuring rod 1, the upper and lower ends of the measuring rod 1 being slidably fitted into the rod sleeves 8 at the upper and lower ends of the case 5, the moving grid seat having a moving grid mounted on the front end face, and a fixed grid (disposed inside the digital display main board) corresponding to the moving grid being disposed in the front case face of the case 5, and a guide member 6 being screwed onto the left or right side of the measuring rod 1, the guide member 6 being slidably mounted in the upper and lower slide rails via a slider 7, as shown in Figures 4(a) and 4(b).

[0023] The movable grid base includes a grid plate 2 at the front and a grid base 3 at the rear. A rod hole slightly forward is centrally located inside the grid base 3. The radius of the rod hole is greater than the distance from the center of the hole to the front end face of the grid base 3, forming an upward and downward groove on the grid base 3. Symmetrical screw holes (smooth holes) are formed on the left and right sides of the rod hole, extending forward and backward. The grid base 3 is fitted onto the measuring rod 1, with the measuring rod 1 exposed through the groove on the front end face of the grid base 3. Figure 3 As shown.

[0024] Each screw hole on the grid seat 3 is aligned with a threaded hole extending forward and backward on the grid plate 2. The movable grid is located on the front end face of the grid plate 2, and the rear end face of the grid plate 2 is attached to the exposed rod body of the measuring rod 1. A certain gap is maintained between the grid plate 2 and the grid seat 3. Screws 4 are inserted through each screw hole of the grid seat 3, and each screw 4 is screwed into the corresponding threaded hole on the grid plate 2. After rotating the grid plate 2 to adjust the parallelism between the movable and fixed grids, each screw 4 is tightened (the rod hole slightly deforms under tension to clamp the measuring rod 1) to secure the grid plate 2 and the grid seat 3 to the measuring rod 1. The required gap between the movable and fixed grids can be achieved by changing the thickness of the grid plate 2. Figure 1 , Figure 2 , Figure 3 As shown.

[0025] As shown in Figures 4(a) and 4(b), the measuring rod 1 drives the split moving grid seat to move up and down inside the case 5 through the guiding action of the slider 7 and the guide 6. The gap and parallelism between the moving grid and the fixed grid are guaranteed by the assembly relationship of the grid plate 2, the grid seat 3 and the measuring rod 1.
