Embodiment Construction

[0015] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0016] Such as Figures 1 to 4 As shown, a checker for detecting the processing size of a gear includes a cylindrical shell with a closed bottom, the inner wall of the cylindrical shell is provided with a groove meshing with the gear, and the bottom of the cylindrical shell is provided with a gear shaft. The holes match the cylindrical protrusions, and the two sides of the cylindrical shell are hinged with a measuring device for measuring the depth of the gear teeth. The measuring device includes an L-shaped base and a movable plate connected to the L-shaped base. With chute.

[0017] Preferably, the depth of the cylindrical shell is equal to the thickness of the gear, and the thickness of the gear can be known according to the depth of the cylin...

Abstract

The invention discloses a checking fixture for detecting the machining dimension of a gear. The checking fixture comprises a cylindrical housing with a closed bottom. The inner wall of the cylindrical housing is provided with a groove engaged with the gear. The bottom of the cylindrical housing is provided with a cylindrical protrusion matching a gear shaft hole. Both sides of the cylindrical housing are hinged to a measuring device for measuring the depth of gear teeth. The measuring device comprises an L-shaped base and a movable plate connected to the L-shaped base. The L-shaped base is provided with a chute. When the machining dimension of the gear is detected, the gear is placed in the cylindrical housing. If the gear is engaged with the groove and is flush with the surface of the cylindrical housing, the shaft hole internal diameter, the external diameter, the thickness and inter-gear distance of the gear satisfy requirement. The movable plate of the measuring device is adjusted so as to be tightly clamped to the gear, thus, the depth of gear teeth can be known through scales. The checking fixture can easily and quickly detect the machining dimension of the gear, is simple in structure and convenient in operation.

Description

technical field [0001] The invention relates to a checking tool, in particular to a checking tool for testing gear processing dimensions. Background technique [0002] Inspection fixture is a simple tool used by industrial production enterprises to control various sizes of products, improve production efficiency and control quality, and is suitable for mass-produced products. When testing whether the gear is qualified, it is necessary to detect the inner diameter of the shaft hole of the gear, the outer diameter of the gear, the thickness of the gear, and the spacing and depth of the gear teeth. There are many testing procedures, which are time-consuming and labor-intensive. For this reason, we propose a checking tool for testing the processing size of gears. Contents of the invention [0003] The main purpose of the present invention is to provide a checking tool for detecting the processing size of gears, which can conveniently and quickly detect whether the gears are q...
