Problems solved by technology

In order to distribute lubricating oil to the entire working surface of the bearing and the shaft, oil holes are usually provided in the non-load-bearing area of ​​the inner ring of the bearing, and the oil holes are used for oil passage and oil supply. For the processing of inclined oil holes, if the ordinary hole processing method is used for direct drilling, since the center of the hole is not perpendicular to the drilling plane, the force on one side of the drill bit acts on the radial force on the cutting edge of the drill bit. The component force will make the axis of the drill bit bend to one side, causing the drill bit to shift and slip, it is difficult to ensure the verticality of the hole drilling, and the drill bit is easy to chip or break

specific Embodiment approach 1

[0048] Specific implementation mode one: combine Figure 10 to Figure 13 Describe this embodiment mode, a kind of oblique oil hole drilling template described in this embodiment comprises drilling template body 13, pressure plate 14, nut 15 and bolt 16, and the upper surface of drilling template body 13 is provided with processing groove 13-1, and bolt 16 vertical It is directly arranged in the processing groove 13-1, and the pressing plate 14 and the nut 15 are successively set on the top of the bolt 16. The drill template body 13 is a cylinder with a regular hexagonal cross section, and three non-adjacent outer walls of the drill template body 13 A guide through hole 18 is provided in each case.

[0049] The jig body 13 is designed as a hexahedral structure. When drilling the inclined oil hole 8, the workpiece is placed in the processing groove 13-1, and the positioning pin 19 is inserted into the end surface of the workpiece from the dowel hole 17 at the bottom of the jig b...

specific Embodiment approach 2

[0050] Specific implementation mode two: combination Figure 10 to Figure 13 To illustrate this embodiment, the angle a between the outer wall 18 - 1 and the horizontal plane corresponding to each guide through hole 18 of an inclined oil hole drilling jig described in this embodiment is 37°±5′. This angle setting is used to ensure the angle of drilling inclined oil holes. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0051] Specific implementation mode three: combination Figure 10 to Figure 13 To illustrate this embodiment, the processing groove 13-1 of the inclined oil hole drilling jig described in this embodiment is a circular groove. The inner contour of the processing groove 13-1 is adapted to the outer contour of the workpiece, and is used for placing the workpiece to be processed. Other components and connections are the same as those in the first embodiment.

Abstract

The invention relates to a drilling jig device for a oblique oil hole of an inner ring double-flange roller bearing and a method for machining the oblique oil hole of the inner ring bearing through the oblique oil hole drilling jig, in particular to an oblique oil hole drilling jig and a method for machining an inner ring bearing oblique oil hole through the oblique oil hole drilling jig, and belongs to the field of mechanical bearing machining. The problem that in the oblique oil hole machining process in the prior art, the position of the hole and the perpendicularity requirement of drillingcan hardly be guaranteed, so that oblique oil hole machining is difficult is solved. The oblique oil hole drilling jig comprises a drilling jig body, a pressing plate, a nut and a bolt. A machining groove is formed in the upper surface of the drilling jig body, the bolt is vertically arranged in the machining groove, and the pressing plate and the nut sequentially sleeve the upper portion of thebolt. The drilling jig body is a column with an orthohexagonal cross section, and a guide through hole is formed in each of three non-adjacent outer walls of the drilling jig body.

Description

technical field [0001] The invention relates to the field of mechanical bearing processing, in particular to a drilling mold device for an inclined oil hole of an inner ring double rib roller bearing and a method for processing the inclined oil hole of the inner ring bearing by the inclined oil hole drilling mold. Background technique [0002] Roller bearings are a type of rolling bearings and are one of the most widely used components in modern machinery. It relies on the rolling contact between the main elements to support the rotating parts. In order to distribute lubricating oil to the entire working surface of the bearing and the shaft, oil holes are usually provided in the non-load-bearing area of ​​the inner ring of the bearing, and the oil holes are used for oil passage and oil supply. For the processing of inclined oil holes, if the ordinary hole processing method is used for direct drilling, since the center of the hole is not perpendicular to the drilling plane, ...
