A fully automatic testing machine for cross shaft universal joints

Abstract

The invention discloses a crossing shaft universal joint automatic detection machine, comprising a material conveying rack, a feeding device, a track on the rear end of the material conveying rack, a clamp rod, a plurality of clamps arranged on the clamp rod, a first vertical pushing member and a second transverse pushing member which are connected to the clamp rod, a plurality of measurement sensors, a third pushing member for fixing the measurement sensor and a central processor connected to the measurement sensor; the clamping block is connected to a vertical track and is provided with a vertical pushing member; the vertical guide rail is vertically connected to a horizontal movement block; the vertical movement block is connected to the horizontal pushing member; the clamping block is provided with a groove hole which is internally provided with an electromagnetic block; the electromagnetic block is connected to a gravity sensor; and the gravity sensor is connected to the central processor. The invention enables the position of the crossing shaft universal joint to be accurate when the crossing shaft universal joint enters the track, and can screen the crossing shaft universal joints having big difference in quality in advance through arranging the gravity sensor on the material feeding device.

Description

【Technical field】 [0001] The invention relates to the technical field of mechanical detection, in particular to the technical field of a cross-axis universal joint automatic detection machine. 【Background technique】 [0002] The universal joint is a machine that realizes variable-angle power transmission, and it is used to change the position of the transmission shaft. It is the "joint" part of the universal transmission of the automobile drive system. In the field of auto parts, the dimensional accuracy of the cross shaft universal joint is very high, and the cross shaft universal joint needs to be specially measured after the machining is completed. [0003] The main size indicators in the cross shaft universal joint are the outer diameter of the shaft head and the length of the shaft. At present, there is a cross shaft universal joint automatic detection machine (CN 201059950), which includes a vertically placed feeding rack, and a feeding rack The connected first transv...

Problems solved by technology

However, in the process of use, it often happens that the position of the cross-axis universal joint pushed into the track by the first transverse material is inaccurate, which affects subsequent measurements and cannot be pre-screened for cross-axis universal joints with large quality differences.
