Abstract
The utility model discloses a main shaft bearing oil filler point processing frock, including upper cover plate, riser, location axle, drill bushing. The upper cover plate is provided with a positioning shaft and a drill bushing, the positioning shaft and the upper cover plate are connected through a nut, and the drill bushing is in interference fit. The upper cover plate and the vertical plate are welded. The tool can ensure the position degree of the oil filling hole during machining, and the drilling machining is directly installed on the installation hole of the outer ring of the main shaft bearing through the positioning shaft, so that the installation and positioning are simple and convenient, the machining efficiency is improved, and the production cost is reduced.
Description
Technical Field
The utility model relates to a hole processing frock, especially a main shaft bearing oil filler point processing frock.
Background
The main shaft bearing is a special tapered roller bearing and mainly comprises an outer ring, a first inner ring, a second inner ring, a retainer, a rolling body and the like. In order to protect the inner and outer ring raceways, an oil hole is formed in the outer ring, and oil is injected into the raceways through the outer ring oil hole after the bearing assembly is completed. Because the oil filler point is on the external diameter and the terminal surface of outer lane, need the setting-out alignment position when processing the hole. Therefore, manual line drawing wastes time and has large position error, and the end face oil filling hole is vertical to the outer diameter oil filling hole, so that the drill bit is easy to break during machining. Special tooling needs to be manufactured. The machining of the oil injection hole at the position 2 can be completed at one time by the tool, the machining time is prolonged, and the production cost is saved.
SUMMERY OF THE UTILITY MODEL
The utility model provides a main shaft bearing oil filler point processing frock to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a main shaft bearing oil filler point processing frock, includes riser, upper cover plate, drill bushing, location axle, nut. The vertical plate is provided with a drill bushing hole, and the upper cover plate is provided with a drill bushing hole and a positioning hole. In the spindle bearing oil injection hole machining tool, the drill bushing hole on the vertical plate is used for installing a drill bushing; and the drill bush hole and the positioning hole on the upper cover plate are used for installing the drill bush and the positioning shaft.
According to the main shaft bearing oil injection hole machining tool, the perpendicularity between the drill bushing on the vertical plate and the positioning shaft is phi 0.1mm, and the parallelism between the drill bushing on the upper cover plate and the positioning shaft is 0.1 mm.
The vertical plate and the upper cover plate are connected in a welding mode.
According to the main shaft bearing oil filler point processing tool, the drill bushing determines the size of the drill bushing according to the minimum aperture of the oil filler point, and the positioning shaft is determined according to the size of the mounting hole.
The beneficial effects of the utility model are that, fix a position through location axle and main shaft bearing outer lane mounting hole and be connected, process through the drill bushing on the riser to the last notes oilhole of main shaft bearing outer lane, a whole set of frock simple installation practices thrift setting-out and process time to improve the processing demand and guarantee compatibility, low cost.
Drawings
Fig. 1 is a schematic view of the structure of the present invention;
fig. 2 is a left side view structure diagram of the present invention.
In the figure: 1 vertical plate, 2 upper cover plates, 3 drill bushings, 4 nuts and 5 positioning shafts
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
The utility model provides a main shaft bearing oil filler point processing frock as shown in fig. 1-2, including riser 1, upper cover plate 2, drill bushing 3, nut 4, location axle 5. The vertical plate 1 is provided with a drill bush 3, and the upper cover plate 2 is provided with the drill bush 3 and a positioning shaft 5. The upper cover plate is connected with the vertical plate in a welding mode, and the positioning shaft is connected with the upper cover plate through a nut.
In order to ensure the position degree of the oil filling hole, an upper positioning shaft of an upper cover plate is connected and positioned with an installation hole on an outer ring of a main shaft bearing, a vertical plate is tangent to the outer diameter of the outer ring, and the upper cover plate is tangent to the end face of the outer ring.
In order to increase the durability of the tool, the drill sleeve needs heat treatment, and the heat treatment hardness is HRC 55-60.
