Description

Dial indicator fine tuning tool

Technical Field

The utility model relates to mechanical measurement technical field, in particular to percentage table fine setting frock.

Background

The dial indicator is a typical universal indicator gauge, and plays an important role in checking the shape accuracy of a part. In the inspection process of a machined workpiece, the fine adjustment dial indicator is an important link for accurately measuring the shape precision of the workpiece. The existing dial indicator extension bar with lower cost is not provided with a fine adjustment device, is very inconvenient to use, and has unstable state when adjusting a gauge head, thereby influencing the processing and inspection efficiency.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a dial indicator fine setting frock. This frock is finely tuned to the percentage table when using, and the regulation action is few, and stability is strong and improved the efficiency of inspection.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a dial indicator fine adjustment tool comprises an M-shaped adjustment block, wherein the M-shaped adjustment block comprises two branches and an elastic connection part between the two branches; the tail parts of the two branches are respectively provided with a threaded hole and a blind hole which are positioned in the same central axis, and the two branches are connected through a screw which passes through the threaded hole and the blind hole; the two branches comprise an upper branch and a lower branch, a mounting hole for mounting a dial indicator clamping handle is formed in the head positive end surface of the upper branch, and the central axis of the mounting hole is perpendicular to the central axis of the threaded hole; the tail part of the lower branch section is provided with an installation position of the dial indicator clamping device.

Furthermore, a locking screw for locking the dial indicator clamping handle is further arranged on the upper branch section, and the locking screw is located on the side of the mounting hole and extends into the mounting hole.

Furthermore, the locking screw is perpendicular to the central axis of the mounting hole.

The utility model adopts the beneficial effect that above-mentioned technical scheme produced lies in:

1. the utility model utilizes the principle of material deformation, adjusts the nut, drives the end part of the dial indicator to return to zero, and then the dial indicator is normally used and starts to move; the adjustment amplitude is smaller and more stable.

2. The utility model discloses effectively avoided at the in-process fish tail finished piece surface of adjusting the percentage table, reduced the regulation action, reduced the inspection degree of difficulty, reached the purpose that improves production efficiency.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Fig. 2 is a schematic structural diagram of the calibration block in fig. 1.

Fig. 3 is a schematic view of the structure of the usage state of the present invention.

In the figure: 1. the device comprises a calibration block, 2 percent meters, 3 percent meter clamping devices, 4 percent locking screws, 5 percent screws, 1.1 percent mounting holes, 1.2 percent blind holes, 1.3 percent mounting positions.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

The following is a more specific example:

referring to fig. 1, the present embodiment includes a screw 5, a locking screw 4, and an alignment block. Referring to fig. 2, the upper branch knot and the lower branch knot of the adjusting block are respectively provided with a threaded hole and a blind hole which are matched with the screw, the threaded hole is positioned on the lower branch knot, and the blind hole is positioned on the upper branch knot.

The two branches are connected through a screw penetrating through the blind hole 1.2 and the threaded hole; a mounting hole 1.1 for mounting a dial indicator clamping handle is formed in the head positive end face of the upper branch section, and the center line of the mounting hole is perpendicular to the center line of the screw hole; the tail of the lower branch of the adjusting block 1 is provided with an installation position of a dial indicator clamping device, and the installation position 1.3 is a through hole.

Referring to fig. 3, the using method of the embodiment is to install the dial indicator 2 and the dial indicator clamping device 3 in place respectively; the tip of the dial indicator touches the surface of the workpiece, the bolt is rotated, the dial indicator is slightly adjusted to return to zero by means of deformation of the workpiece, the workpiece is moved, and the workpiece is measured.

The above description is only an embodiment of the present invention, but the present invention is not limited to the embodiment. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit and principle of the invention, and the equivalents or substitutions are included in the scope defined by the claims of the present application.
