Description

Clutch roller matching device and method Technical Field The invention relates to the technical field of clutches, in particular to a clutch roller matching device and a method. Background The clutch is an important transmission assembly, and the structure of the clutch generally comprises an outer ring, an inner ring and a retainer arranged between the outer ring and the inner ring, wherein a plurality of rollers are uniformly arranged on the retainer along the circumferential direction of the retainer. In order to realize the control of power transmission, the inner peripheral wall of the outer ring is always provided with cam grooves which are in one-to-one correspondence with a plurality of rollers, and the depth of the cam grooves is changed along the circumferential direction and generally comprises a large end and a small end which are communicated with each other. The working principle of the clutch is based on the position change of the roller in the cam groove, when the clutch is in a combined state, the roller is wedged into the small end of the cam groove under the action of a spring or other force application elements to form gapless rigid contact with the inner ring roller paths so as to drive the outer ring and the inner ring to synchronously rotate to realize torque transmission, when the clutch is in a separated state, the roller moves to the large end of the cam groove, and a specific gap, namely a play called in the industry, is reserved between the roller and the inner wall of the large end of the cam groove of the outer ring so as to ensure free relative rotation between the inner ring and the outer ring and realize power cutting. However, in the existing manufacturing process, the cam groove is used as a special-shaped curved surface structure on the inner wall of the outer ring, and the shape is not regular, so that the critical dimensions such as the large end depth, the contour curve and the like are difficult to perform high-precision rapid measurement. In the actual production process, the play is often detected after the clutch is integrally assembled. Once the play is found to be unacceptable, the play can only be adjusted by disassembling and replacing rollers of different specifications for reassembly, as the size of the cam groove is difficult to correct online. The assembly-detection-reworking process seriously affects the continuity of the production line, not only increases the cost of repeated labor, but also greatly reduces the overall assembly efficiency of the clutch. Disclosure of Invention The invention aims to solve the technical problems that in the prior art, the clearance can be detected only after the whole assembly of a clutch is finished, and once the clearance is found to be unqualified, the clearance can be adjusted only by disassembling and replacing rollers with different specifications for reassembling, so that the cost of repeated labor is increased, the whole assembly efficiency of the clutch is greatly reduced, and the clutch roller matching device and method are provided. In order to solve the technical problems, the invention adopts the following technical scheme that the clutch roller matching device comprises: A base; the central cone gauge is provided with a conical surface on the peripheral wall, and the central cone gauge is elastically lifted above the base and has an initial position in an initial state; The roller assembly comprises a roller seat fixed above the base and sleeved outside the central cone gauge and a plurality of detection rollers arranged inside the roller seat at intervals along the circumferential direction of the roller seat, a workpiece is sleeved outside the roller seat, the detection rollers can roll inwards under the extrusion of the working face of the workpiece to press the central cone gauge downwards from an initial position to a first position, or the detection rollers can roll outwards under the extrusion of the central cone gauge to be attached to the working face of the workpiece, and the central cone gauge can move upwards from the initial position to a second position; And the measuring assembly is in interference with the central cone gauge and is used for measuring the position of the central cone gauge. Further, the lifting assembly is used for driving the workpiece to lift so as to enable different axial positions of the working face of the workpiece to be in contact with the detection roller. Further, the jacking component comprises a tray, a supporting column supported between the tray and the workpiece, a guide sleeve supported at the bottom of the tray, a cam mechanism for driving the guide sleeve to lift and fall, and an anti-rotation mechanism for limiting the guide sleeve to rotate along with the cam mechanism.
