Embodiment Construction

[0009] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.

[0010] figure 1 It shows the gear press-fit error prevention jig provided by the present invention, including the jig bottom plate 1, the jig bottom plate 1 is provided with a gear groove 2 for accommodating gears, and the bottom surface of the gear groove 2 is provided with a groove 3 matching the step height of the gear end surface , the bottom surface of the groove 3 is provided with a pressure sensor 4 , and the height of the pressure sensor 4 protruding from the bottom surface of the groove 3 is smaller than the depth of the groove 3 .

[0011] The depth of the gear groove 2 is the same as the thickness of the gear, and the radial dimension of the groove 3 is the same as the radial dimension of the step on the end face of the gear, for better positioning.

[0012] The above descriptions are only preferred emb...

Abstract

The invention discloses an error-proof fixture for press fitting of a gear and belongs to the technical field of fixtures. The error-proof fixture comprises a fixture base plate, wherein a gear slot for accommodating a gear is formed in the fixture base plate; a groove matched with the step height of the end face of the gear is formed in the bottom surface of the gear slot; a pressure sensor is arranged on the bottom surface of the groove; the height, protruded out of the bottom surface of the groove, of the pressure sensor, is smaller than the depth of the groove. When a stepped surface of the gear is enabled to be downwards placed in the groove, the press fitting can be started after the pressure sensor senses the pressure; if the stepped surface is upwards placed in the groove, the pressure sensor cannot sense the pressure, and the press fitting cannot be started. According to the error-proof fixture, the error-proof function of the fixture is realized, manual distinguishing is avoided, the press fitting error due to the fact that the gear is reversely placed on the clamp is prevented, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a gear press-fit error-proof fixture. Background technique [0002] The installation of the gear is usually to use a press-fitting machine to press-fit the gear to the main shaft. The difference between the front and back of the gear is only that one of the end faces has a step with a height of about 0.5mm. Every time you press-fit, you need to distinguish the front and back with the naked eye or feel. The gears are easy to be reversed on the fixture, and the press-fitting error rate is high. The reversed gears are difficult to disassemble, and it is easy to cause deformation of other parts such as the main shaft, or even be scrapped. Contents of the invention [0003] The purpose of the present invention is to provide a gear press-fit error-proof jig to solve the problem that the existing jig is difficult to distinguish the front and back of the gear, and the press-fit error ...
