TECHNICAL FIELD
[0001] The utility model relates to bearing seat processing technical field, concretely relates to a bearing seat inclined oil hole processing frock. BACKGROUND
[0002] As Fig. 1-2 The bearing seat 1 has a feature that a plurality of inclined oil holes 11 are arranged on one end surface of the bearing seat 1, and the inclined oil holes 11 are inclined through the inner conical surface of one end of the bearing seat 1. Since the inclined oil holes 11 have a certain inclination angle (30°) relative to the bearing seat axis, it is not easy to process using ordinary machine tools. If a high-end machine tool such as a five-axis numerical control machine tool is used, it can be processed, but most machine processing enterprises do not have such equipment conditions, and the cost of purchasing equipment is too high. Therefore, it is necessary to design a frock to cooperate with ordinary machine tools to complete the processing of the inclined oil holes of the bearing seat. SUMMARY
[0003] The utility model discloses a bearing seat inclined oil hole processing frock, solves the processing problem of the inclined oil hole of bearing seat end part.
[0004] To achieve the above object, the utility model adopts the following technical scheme:
[0005] A bearing seat inclined oil hole processing frock, including base, automatic rotary workbench, the base has the inclined installation surface, and the automatic rotary workbench is fixed on the inclined installation surface, and the angle of the inclined installation surface is same with the inclination angle of the inclined oil hole, the flange hole of the automatic rotary workbench is connected with a locating disc, and the locating disc is used to install the bearing seat to be processed, and the positioning hole on the locating disc is adapted with the flange hole of the end part of the bearing seat.
[0006] Further, the center axis of the locating disc is perpendicular to the inclined installation surface, and is coaxially arranged with the rotation center of the automatic rotary workbench.
[0007] Further, the locating disc is a hollow disc body, and the outer edge of the hollow disc body is provided with a plurality of positioning holes, and the positioning holes are distributed along the circumference.
[0008] Further, the inclination angle of the inclined installation surface is 30°.
[0009] Further, the one end of the bearing seat is provided with 12 inclined oil holes which are uniformly distributed along the circumference.
[0010] Further, the power mechanism of the automatic rotary workbench is a servo motor.
[0011] The utility model has the advantages of:
[0012] This utility model's fixture for machining inclined oil holes in bearing housings involves bolting one end of the bearing housing to a positioning plate via a flange connection. Because the base has an inclined surface with the same angle as the inclined oil hole, the installed bearing housing can be directly drilled using a conventional machine tool such as a drilling machine. The drill bit can simply move straight up and down, and the inclined oil holes distributed along the circumference are machined sequentially using the indexing function of the automatic rotary table. This fixture, utilizing an inclined base and an automatic rotary table, allows for the drilling of these inclined holes on a conventional machine tool, without relying on high-end CNC machine tools. The automatic rotary table is a relatively mature product, thus solving the machining problem without significantly increasing costs. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art are within the protection scope of the present utility model.
[0019] Embodiments of this utility model:
[0020] like Fig. 1-4As shown, a bearing seat inclined oil hole processing tooling includes a base 2, an automatic rotating table 3, the base 2 has an inclined installation surface, and the automatic rotating table 3 is fixed on the inclined installation surface. The base 2 includes a bottom plate 21, two vertical plates 22 and an installation plate 23, the upper side of the vertical plate 22 is an inclined surface for placing the installation plate 23. The upper side of the installation plate 23 forms the inclined installation surface. The angle of the inclined installation surface is the same as the inclined angle of the inclined oil hole 11, and in the embodiment, the angle of the inclined installation surface is 30°. The installation plate 23 is provided with a bolt hole, and a T-shaped groove can also be provided, which is used to connect the automatic rotating table 3, and the connection of the two parts is relatively easy to realize, and other existing connection modes can also be used.
[0021] The automatic rotating table 3 is a purchased part, which is mainly used for accurate indexing, because the bearing seat 1 is provided with 12 inclined oil holes 11 uniformly distributed along the circumference, and after one hole is processed, the bearing seat 1 needs to be rotated by a certain angle by means of the automatic rotating table 3. The automatic rotating table 3 can adopt a workbench with a model of OBR-255. The power mechanism of the automatic rotating table 3 is a servo motor, which can accurately index according to needs. The structure and principle of the automatic rotating table 3 are relatively mature, so the utility model is not limited in specific model, and other models of the automatic rotating table 3 can also be used. The price of the automatic rotating table 3 is about 5000 yuan, which not only solves the problem of processing the inclined oil hole 11, but also can be used in other workpiece processing scenes. Therefore, it is easy for most processing enterprises to configure, and the machining problem is met without high cost.
[0022] In order to better adapt to the bearing seat 1 to be processed, a positioning disc 4 is designed. The positioning disc 4 is a hollow disc body, and a plurality of positioning holes are arranged on the outer edge of the hollow disc body and are distributed along the circumference. One end surface of the positioning disc 4 is connected to the flange hole 12 on the automatic rotating table 3, the center axis of the positioning disc 4 is perpendicular to the inclined installation surface, and the center axis of the automatic rotating table 3 is coaxially arranged with the center of rotation of the automatic rotating table 3.
[0023] The other end surface of the positioning disc 4 is used for mounting the bearing seat 1 to be processed, and the positioning holes on the positioning disc 4 are adapted to the flange holes 12 at the end of the bearing seat 1; the number of the positioning holes can be less than the number of the flange holes 12 on the bearing seat 1, but the circumference where the flange holes 12 are located and the spacing of the flange holes 12 are adapted.
[0024] In the processing and use, the bearing seat 1 is fixed by means of a bolt. The end of the inclined oil hole 11 to be processed of the bearing seat 1 is located outward, and the other end cooperates with the positioning disc 4. Because the base 2 has a 30° inclined surface, the installed bearing seat 1 can be directly drilled by using a common machine tool such as a drilling machine, and the drill bit can be straight up and straight down, and the indexing of the automatic rotating table 3 is used to sequentially process each inclined oil hole 11.
