Pressure head of disposable built-in needle

Abstract

The invention discloses a pressure head of a disposable built-in needle. The pressure head comprises a pressure head of the built-in needle. The pressure head of the built-in needle comprises a pressure shaft and a gear shaft; the gear shaft is a cylinder, and limiting teeth are formed in the outer surface of the front end of the gear shaft; the limiting teeth are uniformly distributed on the outer side wall of the gear shaft; and the pressure shaft is a hollow cylinder. A conventional roller pin assembling mode is fully overturned. The pressure head of the built-in needle is composed of the pressure shaft and the gear shaft. The limiting teeth are formed in the outer surface of the front end of the gear shaft, and a groove is formed between every two limiting teeth for storing a roller pin; when a ring of roller pins is arranged fully on the gear shaft, a power source pushes the pressure shaft toward a bearing retaining rack and the roller pins will climb upward along the bevels formed between the limiting teeth and low toothed surfaces so as to enter a bearing retaining rack window, so that the roller pins can be fully pressed into the retaining rack at one time without damagingthe retaining rack. The rate of finished products is considerably high, and the labor intensity of workers is alleviated greatly and the production efficiency is improved greatly, too.

Description

technical field [0001] The invention belongs to the technical field of bearing processing, and in particular relates to a pressure head with a disposable inner needle. Background technique [0002] Needle roller bearings are roller bearings with cylindrical rollers that are thin and long relative to their diameter. This type of roller is called a needle roller. Although it has a small cross-section, the bearing still has a high load-bearing capacity. The needle roller bearing is equipped with thin and long rollers, so the radial structure is compact, and its inner diameter size and load capacity Same as other types of bearings, the outer diameter is the smallest, especially suitable for support structures with limited radial installation dimensions, and in the assembly process of needle roller bearings with inner needles. [0003] At present, most of the needles are pressed in one by one manually with a vise, and some companies use a semi-automatic mechanism to drive the ne...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a disposable indenter with internal needles to solve the above-mentioned background technology. At present, most of them are manually pressed in with vise one by one, and some companies use semi-automatic mechanisms to press the needles one by one. It is punched in, and the existing assembly method is very labor-intensive and has extremely high requirements for the equal division of the cage window, so the yield and efficiency are extremely low in the assembly process
