Un-pressed part detection device for conical roller bearing

Abstract

The invention belongs to the technical field of bearings, and provides an un-pressed part detection device for a conical roller bearing. The un-pressed part detection device for the conical roller bearing is provided with a bottom plate fixed above the side of a bearing conveying belt. An air cylinder I used for detecting left-and-right movement of the device and an air cylinder II used for detecting up-and-down movement of the device are fixed to the bottom plate. The air cylinder I is located on one side of the bottom plate. An air cylinder body II of the air cylinder II is fixed to an air cylinder body I of the air cylinder I. The air cylinder II is arranged in two guide rods II in bilateral symmetry in a sleeving manner. The guide rods II are arranged vertically, and a base II capableof moving up and down along the guide rods II is arranged at the lower ends of the guide rods II. A clamping mechanism is fixed to the lower end of the base II. The detection device is further provided with an air blowing mechanism used for blowing an assembly in the bearing to rotate and a proximity switch used for detecting signals of a roller and a holder. According to the un-pressed part detection device, the problems that in batched production, screening of un-pressed parts is difficult, efficiency is low, and missing is prone to being caused by manual selection are solved, and operationcost is reduced.

Description

technical field [0001] The invention belongs to the technical field of bearings, and in particular relates to a detection device for unpressed parts used in tapered roller bearings. Background technique [0002] Small tapered roller bearings (inner diameter φ80 or less) are mostly used in automotive gearboxes and differentials. Due to their small size, light weight, and large processing batches, it is uneconomical to rely on manual identification of internal components that are leaking and pressing bad parts during processing. It is also easy to omit, and the unpressed parts are serious quality problems, which will cause the bearings to fall apart, which will seriously affect the assembly of the main engine of the car, resulting in huge claims. Therefore, there is an urgent need for an online automatic device to discriminate the unpressed parts produced during the processing. [0003] The pressing process of the inner components of the tapered roller bearing is shown in Fig...
