Description

Gear straddling distance detection device

Technical Field

The utility model particularly relates to a gear cross bar distance detection device, and belongs to the technical field of measuring calipers.

Background

In the gear production process, the inter-rod distance of the inner gear ring is required to be measured and checked frequently; in the measuring process of the rod spacing of the ring gear, two measuring rods are respectively arranged at the tooth profile, and simultaneously, the rod spacing of the ring gear is measured and checked by using vernier caliper isotopy; in order to improve the work efficiency of quality inspection personnel and simultaneously reduce the working strength of quality inspection personnel and workshop workman, design stick interval contrast slide caliper rule.

Chinese patent application is a vernier caliper with internal spline bars at intervals, and application number is 200810020772.6, and discloses a vernier caliper comprising a ball measuring head, an auxiliary ruler and a main ruler. The main scale is a right-angle component, scales are arranged on the cross rod of the main scale, and the drop rod is a left measuring claw. The auxiliary ruler is also a right-angle-shaped component, the drop rod is a right measuring claw, scales are arranged on the surface of the cross rod of the drop rod, and the auxiliary ruler main body is sleeved on the cross rod of the main ruler and can move left and right. The outer sides of the left measuring jaw and the right measuring jaw are provided with ball measuring heads, and the two ball measuring heads are positioned on the same axis and parallel to the cross rod of the main ruler.

When the measuring ball is replaced, the measuring ball is more troublesome, and the measuring ball needs to be replaced more conveniently and stably because the measuring ball needs to be replaced with different measurement.

Disclosure of Invention

The utility model mainly aims to provide a gear cross rod distance detection device for solving the problems of inconvenient measurement and ball replacement.

The aim of the utility model can be achieved by adopting the following technical scheme:

the gear stick span detection device comprises a vernier caliper and a measuring ball arranged on an outer measuring claw of the vernier caliper, wherein the measuring ball is connected with the outer measuring claw of the vernier caliper through a fixed clamping sleeve.

Preferably, a groove into which the outer measuring claw of the caliper is inserted is formed in the fixing clamping sleeve.

Preferably, the two sides of the fixing clamping sleeve are connected with fastening screws in a threaded manner

Preferably, a protective pad is mounted on the end of the fastening screw contacting the outer measuring jaw.

Preferably, the protection pad is annular.

Preferably, the measuring ball is in threaded connection with the fixing clamping sleeve.

Preferably, a limiting plate is arranged on the inner side of the fixing clamping sleeve.

The beneficial technical effects of the utility model are as follows:

1. specific numerical values do not need to be measured, so that the operation is simpler and the hand is easier to get up; the working difficulty and strength of workshop workers and quality inspection workers can be greatly reduced by comparing the use of the scales, and the working efficiency is improved;

2. through setting up fixed cutting ferrule, the outer measuring jaw of installation measuring ball and slide caliper that can be more convenient.
