Description

Technical Field

[0001] The utility model relates to the technical field of workpiece grinding auxiliary positioning equipment, in particular to a grinding tool for an oil supply ring of a gear box. Background Art

[0002] At present, with the rapid development of the wind power double-fed speed increaser industry, the design requirements for the output stage oil supply ring are also increasing. In order to meet these requirements, the oil supply ring is designed as a ring structure with a protrusion. Figure 1 As shown, the outer ring of the oil supply ring has a top surface that protrudes upward from the upper side of the oil supply ring, while the inner ring is provided with an annular protrusion that protrudes downward. This design is intended to add a sealing ring groove to the sealing structure of the gearbox to achieve a better sealing effect.

[0003] In actual application, although the oil supply ring is manufactured according to the requirements of the drawing, there is still a certain margin on the top surface. When assembling the oil supply ring, it is necessary to grind the top surface of the oil supply ring according to the actual measured size. The top surface of the oil supply ring is the matching grinding surface. Usually a grinder is used for grinding. When grinding, the bottom of the oil supply ring is adsorbed on the grinder, and then the matching grinding surface of the oil supply ring is grinded by the grinding mechanism of the grinder.

[0004] However, there are some problems with the grinding process of this oil supply ring with a protrusion. First, because the grinding surface of the oil supply ring faces upward during grinding, the protrusion needs to be supported on the grinder, which causes the grinder to exert a large force on the oil supply ring during grinding, resulting in a large interaction force between the protrusion of the oil supply ring and the grinder, which makes the protrusion of the oil supply ring easily deformed, and then makes the oil supply ring unusable. Secondly, the design requires that the lower side of the oil supply ring be used as the reference surface for grinding, but in actual operation, only the protrusion can be used as the reference for grinding, which cannot meet the requirements of the drawing. Utility Model Content

[0005] In view of the above defects, the technical problem solved by the utility model is to provide a grinding tool for a gearbox oil supply ring, which can position the oil supply ring with an annular protrusion on a grinding machine and avoid contact between the protrusion and the grinding machine, thereby preventing deformation of the protrusion.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A grinding tool for a gearbox oil supply ring includes a positioning ring, a pad and a pressure plate, wherein the pad is fixedly connected to the inner side of the positioning ring, the pressure plate is located above the pad, and the pressure plate is connected to the pad by at least one locking bolt. The positioning ring and the pressure plate are used to clamp the upper and lower sides of the oil supply ring together.

[0008] By adopting the above scheme, in the initial state, the locking bolt is disengaged from the pad, and the pressure plate is separated from the positioning ring. When in use, the lower side of the oil supply ring is supported on the positioning ring, and the protrusion of the oil supply ring is located on the inner side of the positioning ring. The pressure plate is fixed to the pad by bolts, so that the pressure plate and the positioning ring clamp the upper and lower sides of the oil supply ring together, thereby fixing the oil supply ring. The grinding tool is installed as a whole on the grinder, so that the grinding surface of the oil supply ring faces upward, which is convenient for the grinding mechanism to grind the grinding surface of the oil supply ring. Since the lower side of the oil supply ring is supported by the positioning ring, and since the pad separates the protrusion of the oil supply ring from the grinder, during the grinding process, no friction is generated between the protrusion of the oil supply ring and the grinder, thereby avoiding damage to the protrusion of the oil supply ring. In addition, since the lower side of the oil supply ring is supported on the positioning ring, it means that the positioning reference of the oil supply ring is the lower side of the oil supply ring, not the lower side of the protrusion, which is consistent with the design requirements of the drawing and meets the design requirements.

[0009] The utility model is further configured such that at least one adjusting hole is provided on the side of the positioning ring, and an adjusting bolt is threadedly connected to the adjusting hole, and one end of the adjusting bolt abuts against the side of the backing plate. Through the adjusting bolt, on the one hand, the backing plate and the positioning ring can be fixed together; on the other hand, since the protrusions of different oil supply rings protrude from the lower side of the oil supply ring at different heights, after loosening the adjusting bolt, the backing plate can move along the axial direction of the positioning ring, thereby adapting to the protrusions of different heights on different oil supply rings.

[0010] The utility model is further configured that the adjustment holes are provided with a plurality of intervals along the axial direction of the positioning ring, and an adjustment bolt is threadedly connected in each of the adjustment holes. The backing plate can be fixed at different positions of the positioning ring along the axial direction by the plurality of adjustment bolts, thereby expanding the range of movement of the backing plate along the axial direction of the positioning ring, thereby expanding the adaptation range to the oil supply ring.

[0011] The utility model is further configured such that the outer diameter of the positioning ring is larger than the outer diameter of the oil supply ring. Since the outer diameter of the positioning ring is larger than the outer diameter of the oil supply ring, the upper side surface of the positioning ring is equivalent to the lower side surface of the oil supply ring, which is convenient for locating the lower side surface of the oil supply ring by a depth gauge and measuring the distance between the lower side surface and the upper side surface of the oil supply ring, thereby facilitating determination of whether the grinding is in place.

[0012] The utility model is further configured such that at least one measuring groove is provided on the side of the positioning ring. Due to the provision of the measuring groove, the upper and lower sides of the oil supply ring can be clamped with a caliper to determine whether the oil supply ring is polished in place. By using a variety of detection tools to detect whether the oil supply ring is polished in place, errors caused by using a single detection tool can be avoided, thereby improving measurement accuracy.

[0013] The utility model is further configured that the measuring grooves are provided with a plurality of intervals along the circumference of the positioning ring. Since the measuring grooves are provided with a plurality of intervals, a plurality of measuring points are provided for the caliper to measure the oil supply ring. By measuring a plurality of points on the oil supply ring with a caliper, the grinding detection of the oil supply ring is made more accurate.

[0014] The utility model is further configured such that at least one mounting hole is formed on the pressure plate, a connecting hole corresponding to the mounting hole is formed on the backing plate, and the locking bolt is passed through the mounting hole and is threadedly connected to the connecting hole. The distance between the pressure plate and the backing plate can be adjusted by the locking bolt, thereby adjusting and adapting to oil supply rings of different thicknesses.

[0015] The utility model is further configured that the mounting holes are multiple and evenly distributed on the pressure plate. The multiple locking bolts are connected to the multiple connecting holes in a one-to-one correspondence through the multiple mounting holes, thereby enhancing the stability between the pad and the pressure plate.

[0016] The utility model is further configured that the mounting hole is a countersunk hole. Since the mounting hole is a countersunk hole, the head of the locking bolt can be received in the mounting hole, thereby preventing the head of the locking bolt from affecting the grinding process.

[0017] The utility model is further configured that the pad and the pressure plate are both circular plates. The pad and the pressure plate are circular plates, which makes the adaptability with the annular oil supply ring higher.

[0018] In summary, the present invention provides a gearbox oil supply ring grinding tooling having at least the following features:

[0019] Beneficial effects:

[0020] 1. The oil supply ring can be positioned on the grinder, and the protruding portion of the oil supply ring can be separated from the grinder to prevent the protruding portion from being damaged by the grinder.

[0021] 2. It can provide support for the oil supply ring. The positioning reference of the oil supply ring is the lower side of the oil supply ring, not the lower side of the protrusion. This is consistent with the design requirements of the drawing and meets the design requirements.

[0022] 3. The overall structure is simple and the operation is simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] See also Figure 1-3 The present embodiment provides a grinding tool for a gearbox oil supply ring, comprising a positioning ring 1, a pad 2 and a pressure plate 3. The pad 2 and the pressure plate 3 are both circular plates. The positioning ring 1, the pad 2 and the pressure plate 3 are concentrically arranged, and the pressure plate 3 is located above the pad 2.

Specifically, at least one adjustment hole is provided on the side of the positioning ring 1, and an adjustment bolt 5 is threadedly connected to the inner side of the adjustment hole, and one end of the adjustment bolt 5 is against the side of the pad 2. The side of the pad 2 is pressed against the adjustment bolt 5, so that the pad 2 and the positioning ring 1 are fixed together. The positioning ring 1 and the pressure plate 3 are used to clamp the upper and lower sides of the oil supply ring 9 together. Specifically, the diameter of the pressure plate 3 is larger than the inner diameter of the oil supply ring 9.

Since the lower side of the oil supply ring 9 is supported by the positioning ring 1, and since the pad 2 separates the protrusion 11 of the oil supply ring 9 from the grinding machine, no friction will be generated between the protrusion 11 of the oil supply ring 9 and the grinding machine during the grinding process, thereby avoiding damage to the protrusion 11 of the oil supply ring 9. In addition, since the lower side of the oil supply ring 9 is supported on the positioning ring 1, it means that the positioning reference of the oil supply ring 9 is the lower side of the oil supply ring 9, not the lower side of the protrusion 11, which is consistent with the design requirements of the drawing and meets the design requirements. By adjusting the bolt 5, on the one hand, the pad 2 and the positioning ring 1 can be fixed together; on the other hand, since the protrusions 11 of different oil supply rings 9 protrude from the lower side of the oil supply ring 9 at different heights, after loosening the adjusting bolt 5, the pad 2 can move along the axial direction of the positioning ring 1, so as to adapt to the protrusions 11 of different heights on different oil supply rings 9.
