CN201392162Y - A tool for detecting the position degree of teeth or tooth grooves on a gear shaft - Google Patents

Abstract

The utility model discloses an upper tooth or tooth slot position detecting tool of a gear shaft, which has the advantages of high efficiency, direct reading, easy operation and the like; the structure comprises a detecting tool; the detecting tool is matched with a screw plug; and both ends of the detecting tool are provided with detecting devices. The detection method is as follows: the detecting tool positions with two symmetrical tooth surfaces of a tooth of a gear ring and a tooth slot in the middle; measuring points of the tool are pressed on a normal upper surface of the tooth of the gear ring which has technical requirements by a measuring meter; first a standard part is used to adjust the detecting tool to the zero, and then the detecting tool is used to detect a work piece to be processed, so as to read the deviation value and the offset direction of the processed work piece, and finally measure the processing error.

Description

A tool for detecting the position degree of teeth or tooth grooves on a gear shaft

technical field

The utility model relates to a tool for detecting the position degree of teeth or tooth grooves on a gear shaft.

Background technique

At present, there is a gear shaft with two ring gears, but the number of teeth is different. The design requires that one tooth or tooth slot of one ring gear and one tooth or tooth slot of the other ring gear have positional requirements, as shown in Figure 1. Show. At present, most processing manufacturers take the workpiece down to the three-coordinate measuring machine or inspection platform for measurement. Because the position accuracy is too high, the position will change after it is removed from the machine tool and reinstalled, that is, the repeated installation accuracy makes the position accuracy very high. Difficult to achieve and low measurement efficiency.

Utility model content

The purpose of this utility model is to solve the above problems and provide a detection tool for the position degree of teeth or tooth grooves on the gear shaft with high efficiency, intuitive reading and easy operation.

In order to achieve the above object, the utility model adopts the following technical solutions:

The utility model relates to a tool for detecting the position degree of a tooth or a tooth groove on a gear shaft, which includes a test body, which cooperates with a screw plug, and a detection device is arranged at both ends of the test body.

The detection device is a pair of dial gauges, which are respectively installed in the bushing at the end of the detection body through screws.

A spring is arranged inside the plug, and the spring cooperates with the positioning pin.

The detection method of the detection tool of the utility model is that it utilizes the symmetrical two tooth surfaces of the teeth of one ring gear and the middle one tooth groove to locate, and the measuring point of the tool adopts a dial indicator to press on the tooth of the other ring gear that has technical requirements. In the normal direction, first use the standard parts to set the zero position of the inspection tool, and then use the inspection tool to detect the processed workpiece, so as to read the deviation value and offset direction of the processed workpiece, and finally measure the machining error.

The beneficial effects of the utility model are: the inspection tool adopts the symmetrical two tooth surfaces of the teeth of a ring gear and the positioning of a tooth groove in the middle and the positioning of a section of the shaft diameter of the gear shaft, so that the positioning is stable and the measurement is accurate; the inspection tool of the utility model adopts detection The table compares the readings of standard parts, and the deviation value and offset direction can be read directly, which is convenient and intuitive.
