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

The detection frock of tooth or tooth slot position degree on a kind of gear shaft

Technical field

The utility model relates to the detection frock of tooth on a kind of gear shaft or tooth slot position degree.

Background technology

At present, a kind of gear shaft is arranged, two gear rings are arranged above, but number of teeth difference, the tooth or the teeth groove of tooth of a gear ring of designing requirement or teeth groove and another one gear ring have position degree requirement, see shown in the accompanying drawing 1.The producer of great majority processing at present takes down make a return journey three coordinate measuring machine or verifying bench to workpiece and measures, because the status requirement precision is too high, load onto the position after lifting down once more and just change above lathe, promptly repeat installation accuracy and make position degree requirement be difficult to reach, efficiency of measurement is also low.

The utility model content

The purpose of this utility model is exactly in order to address the above problem, and the detection frock of tooth on a kind of high-level efficiency, the reading a kind of gear shaft directly perceived, maneuverable or tooth slot position degree is provided.

For achieving the above object, the utility model adopts following technical scheme:

The detection frock of tooth or tooth slot position degree on a kind of gear shaft, it comprises a cubing body, the cubing body cooperates with plug screw, is provided with pick-up unit at the two ends of cubing body.

Described pick-up unit is a pair of dial gauge, and they are installed in the lining of cubing end of body by screw respectively.

Described plug screw inside is provided with spring, and spring matches with register pin.

The method that detection frock of the present utility model detects is, it utilizes symmetry two flank of tooth and the middle teeth groove location of the tooth of a gear ring, the frock measurement point adopts dial gauge to be pressed in another gear ring to be had above the normal direction of tooth of technical requirement, give the check frock to zero-bit with standardized element earlier, utilize this check frock to detect processing work again, thereby read the amount of deflection and the offset direction of processing work, finally measure mismachining tolerance.

The beneficial effects of the utility model are: one section diameter of axle location of symmetry two flank of tooth of the tooth of a gear ring of check frock employing and middle teeth groove location and gear shaft, and the location is firm, and measurement is accurately; Check frock of the present utility model adopts and detects table contrast standard part reading, and the amount of deflection and offset direction can directly be read, and be convenient directly perceived.

Wherein, 1. cubing body, 2. plug screw, 3. dial gauge, 4. lining, 5. screw, 6. spring, 7. register pin.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.

Concrete structure of the present utility model such as Fig. 1, Fig. 2, shown in Figure 3, it comprises a cubing body 1, cubing body 1 cooperates with plug screw 2, is provided with pick-up unit at the two ends of cubing body 1.Pick-up unit is a pair of dial gauge 3, and they are installed in the lining 4 of cubing body 1 end by screw 5 respectively.Plug screw 2 inside are provided with spring 6, and spring 6 matches with register pin 7.

Claims

1. the detection frock of tooth or tooth slot position degree on the gear shaft is characterized in that it comprises a cubing body, and the cubing body cooperates with plug screw, is provided with pick-up unit at the two ends of cubing body.

2. the detection frock of tooth or tooth slot position degree is characterized in that on the gear shaft as claimed in claim 1, and described pick-up unit is a pair of dial gauge, and they are installed in the lining of cubing end of body by screw respectively.
