Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing tooling, in particular to a rubber bearing outer circle processing tooling. Background Art

[0002] Rubber bearings are bearings with rubber as the main component, used to support the shaft. Many shaft systems on ships require rubber bearings. At present, the shaft systems on ships have eccentricity problems during rotation due to processing or installation errors. The solution is to correct the eccentricity of the shaft system by installing eccentric rubber bearings. At present, the bearing outer circle processing equipment on the market can generally only process rubber bearings with no eccentricity on the outer circle, and cannot process the outer circle of rubber bearings into an eccentric structure. Utility Model Content

[0003] In order to overcome the shortcomings of the background technology, the utility model provides a rubber bearing outer circle processing tool, which solves the problem that the existing bearing outer circle processing device cannot process the rubber bearing outer circle into an eccentric structure.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A rubber bearing outer circle processing tool, comprising:

[0006] A mandrel, one end of which is provided with an eccentric hole;

[0007] A No. 1 stop plate is arranged at the other end of the core shaft, and the front and rear ends of the No. 1 stop plate are respectively provided with a clamping portion and a No. 1 protrusion for matching with the rubber bearing hole;

[0008] A second limiting plate is arranged on the core shaft, the second limiting plate is provided with a through hole for cooperating with the core shaft, and the second limiting plate is provided with a second protrusion for cooperating with the rubber bearing hole;

[0009] The locking piece is arranged on the core shaft and is used to act on the second limiting plate.

[0010] A threaded section is provided at one end of the core shaft away from the first limiting plate, and the locking member is an adjusting nut used to cooperate with the threaded section.

[0011] A washer sleeve is provided between the adjusting nut and the second limiting plate.

[0012] One end of the core shaft is provided with a connecting piece for threaded cooperation with the core shaft, and the eccentric hole is arranged on the connecting piece.

[0013] The first limiting plate and the second limiting plate are both provided with anti-skid patterns on the sides in contact with the rubber bearing.

[0014] An elastic pin is arranged at the through hole, and a groove for cooperating with the elastic pin is arranged on the core shaft.

[0015] The first limiting plate and the second limiting plate are both circular plates, and the diameters of the first limiting plate and the second limiting plate are both smaller than the outer diameter of the rubber bearing.

[0016] The beneficial effects of the utility model are:

[0017] The No. 2 limit plate can move on the core shaft. When the two ends of the rubber bearing are respectively fitted with the No. 1 limit plate and the No. 2 limit plate, the No. 1 raised part and the No. 2 raised part cooperate with the rubber bearing hole to ensure that the rubber bearing is set in the center. Then the locking piece acts on the No. 2 limit plate to position the rubber bearing. Finally, the chuck of the machine tool clamps the clamping part, and the ejector pin presses the eccentric hole to perform eccentric processing on the outer circle of the rubber bearing. The tooling is simple and convenient for eccentric processing of the outer circle of the rubber bearing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0023] In the embodiment, Figure 1 , Figure 2 As shown, a rubber bearing outer circle processing tool comprises:

[0024] A mandrel 1, one end of which is provided with an eccentric hole 2;

[0025] A first stop plate 3 is arranged at the other end of the core shaft 1, and the front and rear ends of the first stop plate 3 are respectively provided with a clamping portion 4 and a first protrusion 5 for matching with the rubber bearing hole;

[0026] A second limiting plate 6 is arranged on the core shaft 1, the second limiting plate 6 is provided with a through hole 7 for cooperating with the core shaft 1, and the second limiting plate 6 is provided with a second protrusion 8 for cooperating with the rubber bearing hole;

[0027] The locking member 9 is arranged on the core shaft 1 and is used to act on the second limiting plate 6 .

[0028] The No. 2 limiting plate 6 can move on the core shaft 1, and when the two ends of the rubber bearing are respectively fitted with the No. 1 limiting plate 3 and the No. 2 limiting plate 6, the No. 1 raised portion 5 and the No. 2 raised portion 8 cooperate with the rubber bearing hole to ensure that the rubber bearing is centrally arranged, and then the No. 2 limiting plate 6 is acted on by the locking member 9 to position the rubber bearing; finally, the chuck of the machine tool clamps the clamping portion 4, and the ejector pin pushes against the eccentric hole 2 to perform eccentric processing on the outer circle of the rubber bearing. The tooling is simple and convenient for eccentric processing of the outer circle of the rubber bearing.

[0029] In the embodiment, Figure 1 , Figure 2 As shown, the end of the mandrel 1 away from the first limiting plate 3 is provided with a threaded section 10, and the locking member 9 is an adjusting nut for cooperating with the threaded section 10. The first limiting plate 3 can be tightened or loosened by rotating the adjusting nut, which is convenient for adjustment.

[0030] In the embodiment, Figure 1 , Figure 2 As shown, a washer sleeve 11 is provided between the adjusting nut and the second limiting plate 6. By replacing the washer sleeve 11 of different lengths, rubber bearings of different lengths can be limited.

[0031] In the embodiment, Figure 1 , Figure 2 As shown, one end of the mandrel 1 is provided with a connector 12 for threaded cooperation with the mandrel 1, and the eccentric hole 2 is arranged on the connector 12. The connector 12 can be a bolt, and by replacing the bolts arranged at different positions of the eccentric shaft 2, it is suitable for processing different rubber eccentric bearings, and has good universality.

[0032] In the embodiment, Figure 1 , Figure 2 As shown, the first and second limit plates 3 and 6 are provided with anti-skid patterns 13 on the sides in contact with the rubber bearing. The anti-skid patterns 13 increase the friction force after the first and second limit plates 3 and 6 clamp the rubber bearing, preventing the rubber bearing from rotating relative to the first and second limit plates 3 and 6 during processing, thereby affecting the processing accuracy.

[0033] In the embodiment, Figure 1 , Figure 2 , Figure 3 As shown, the through hole 7 is provided with an elastic pin 14, and the core shaft 1 is provided with a groove 15 for cooperating with the elastic pin 14. The elastic pin 14 cooperates with the groove 15 to ensure that the second limit plate 6 does not rotate circumferentially, thereby preventing the second limit plate 6 from driving the rubber bearing to rotate relative to the core shaft 1, thereby ensuring the processing accuracy.

[0034] In the embodiment, the first limit plate 3 and the second limit plate 6 are both circular plates, and the diameters of the first limit plate 3 and the second limit plate 6 are both smaller than the outer diameter of the rubber bearing. When the outer circle of the rubber bearing is eccentrically processed, the cutter head will not act on the first limit plate 3 and the second limit plate 6.

[0035] Obviously, the above embodiments of the present invention are merely examples for illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to provide all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still fall within the scope of protection of the present invention.
