specific Embodiment approach 1

[0032] Embodiment 1: a positioning device for rollers; it includes a roller clamping mechanism 1, a motor 2, and a pulley 3, and a side end surface of one end of the roller clamping mechanism 1 is provided with a plurality of pulleys 3, and a plurality of pulleys 3 The outer edge of the roller is connected by a belt, the rotor of the motor 2 is connected with the belt, and the motor 2 is fixed on the roller clamping mechanism 1.

[0033] A plurality of pulleys are connected with the motor to realize the first-stage deceleration of the pulleys and the transmission of the pulleys. The number and distribution positions of the pulleys are affected by the deceleration ratio of the first-stage deceleration.

specific Embodiment approach 2

[0034] Embodiment 2: There are two pulleys 3 on the upper end of the roller clamping mechanism 1, and the axes of the two pulleys 3 are arranged horizontally and parallel.

[0035] Other implementation manners are the same as the specific implementation manner 1.

[0036] Two belt pulleys are set on the top to meet the simultaneous processing requirements of two sets of mixed wheels, ensuring the consistency and precision of the two rollers, thereby ensuring the machining accuracy of the bearing ring.

specific Embodiment approach 3

[0037] Embodiment 3: The bottom end of the roller clamping mechanism 1 is provided with an electromagnetic chuck.

[0038] Other implementation manners are the same as the specific implementation manner 1.

Abstract

The invention belongs to the field of machining, particularly relates to a roller positioning device and a method for grinding an outer circle of a roller through the roller positioning device, and aims to solve problems that in a traditional roller machining process, precision of an inner diameter of the roller influences precision of an outer diameter, and errors exist in secondary installationof the roller. A roller and a pressing rolling shaft are combined and then installed on a set of positioning driving device to be driven by a driving motor to rotate, then the whole set of device is fixed to a workbench of a reciprocating type surface grinding machine through an electromagnetic chuck, the reciprocating workbench drives the positioning driving device to do the reciprocating motion,and a grinding wheel feeds in the radial direction to grind the outer diameter of the roller. The method is advantaged in that a precision error between the inner diameter of the roller and a pressing rolling shaft and the error of the roller installed on the pressing rolling shaft are overcome, the error caused by the mutual relation between the inner diameter of the roller and the pressing rolling shaft is avoided, the roller and the pressing rolling shaft are machined after being combined, consistency and precision of the roller are guaranteed, and thereby machining precision of the bearing ring is guaranteed.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a positioning device for a roller and a method for grinding the outer circle of the roller by using the same. Background technique [0002] In the grinding process of miniature bearings, the use of rollers for clamping and driving is a commonly used structure. The accuracy of the roller directly affects the processing accuracy of the product, so the trimming of the roller is an important link to ensure the accuracy of the product. The current process for grinding rollers is to use a universal cylindrical grinder to grind the outer circle of the roller. It is to hold the roller on the workpiece shaft by a special fixture, and use the outer circle of the emery wheel to grind. [0003] Since this method relies on the inner diameter of the roller for radial positioning, the machining accuracy of the inner diameter of the roller and the positioning accuracy of the inn...
