Abstract

The invention discloses an automatic assembling device for a needle roller bearing; the automatic assembling device comprises an automatic material loading mechanism, an automatic grease injection mechanism, an automatic needle loading mechanism and an automatic needle roller detecting mechanism, wherein a turntable I connected with a motor I is arranged on a bracket of a stand, a guardrail and a material outlet passage are arranged on the periphery of the stand, the guardrail is provided with a cross rod, the lower part of the cross rod is provided with guide plates; the automatic grease injection mechanism comprises a material conveying passage, a material pushing cylinder I, a locating cylinder I and a grease injection passage, and a clamping and locating seat is arranged in front of the locating cylinder I; the automatic needle loading mechanism is provided with a conveying belt device, a material pushing cylinder II is connected below a locating bottom plate; a locating cylinder II connected with a locating block is arranged above the locating bottom plate, a fixing block is mounted on the locating cylinder II, a needle roller guide block, a needle loading plate and an upper end cover are arranged above the locating block in sequence, a needle hole is formed in the upper end cover, a central shaft is arranged at the central part of the upper end cover, and the upper end of the central shaft is connected with a turntable II connected with a motor II; the automatic needle roller detecting mechanism comprises a detecting cylinder provided with a probe at the head part of the detecting cylinder and arranged on a small bracket outside the needle locating plate, a detecting hole is formed in the needle roller guide block, and a displacement sensor is arranged on the cylinder side. As materials are automatically loaded, greases are automatically injected and needles are automatically loaded, the automatic assembling device for the needle roller bearing, disclosed by the invention, has the advantages of high automation and stable quality.

Description

technical field [0001] The invention belongs to the technical field of bearing assembly equipment, and in particular relates to automatic assembly equipment for needle roller bearings. Background technique [0002] In the past, manual operation was generally used for the needle installation of constant-velocity drive shafts in the automotive industry, and four people were required to work together, including grease application, needle installation, wire retaining ring and needle roller retaining ring installation, and final assembly. This assembly The process efficiency is very low, and it is easy to cause phenomenon such as uneven grease application, inverted needles and missing needles, which affect product quality and production progress. Now, there is a semi-automatic needle loading machine on the market, which roughly adds needle rollers manually, the needle rollers are smoothed out by motor vibration, and then the needle rollers are sent into the needle rollers manuall...
