Description

A kind of side wall drilling fixture for cylindrical parts

technical field

The utility model belongs to the field of automobile parts processing, in particular to a drilling fixture.

Background technique

The plunger of the plunger pump for automobile oil supply has a similar cylindrical part, and its side wall needs to drill a small hole perpendicular to the centerline at the designated position.

Due to the cylindrical structure of the parts, it is difficult to clamp and locate, and it is also difficult to determine the position and direction of the drill bit. Usually, it can only be clamped and CNC processed by a precise multi-degree-of-freedom drilling machine, and ordinary drilling machines cannot be used.

However, such advanced equipment not only has high cost, inconvenient maintenance, but also inconvenient loading and unloading operations, which seriously affects the processing efficiency.

Utility model content

In order to solve the problem that the ordinary drilling machine is difficult to meet the processing requirements, and the multi-degree-of-freedom precision drilling machine has high cost and low efficiency, the utility model discloses a cylindrical part side wall drilling fixture, which is used to clamp and fix the parts. Ordinary drilling machine can meet the processing requirements.

To achieve the above object, the utility model adopts the following technical scheme:

A side wall drilling fixture for cylindrical parts, comprising a fixture body with a flat bottom surface, the body is provided with accommodating holes for accommodating parts along the horizontal direction, and the top surface of the body is provided with a through hole for a drill bit to pass vertically. One end of the accommodating hole is provided with a limit plate perpendicular to the center line of the accommodating hole.

Compared with the prior art, the utility model has the following beneficial effects:

When using, just put the through hole of the fixture facing the drill bit, fix the fixture, insert the part into the accommodating hole, clamp it with your hand and the limit plate, press the drill bit down through the through hole to drill the part. The hole operation can meet the processing requirements. Because the common radial drilling machine can be used, the cost is low, the fixture structure is simple, the loading and unloading is convenient, and the processing efficiency is significantly improved.

Other advantages, objects and features of the present invention will be apparent in part from the description below, and in part will be understood by those skilled in the art from the study and practice of the invention.

Description of drawings

Figure 1 is a schematic structural diagram of a cylindrical part sidewall drilling fixture of the present invention.

FIG. 2 is a schematic structural diagram of another angle of a side wall drilling fixture of a cylindrical part of the present invention.

The reference numerals in the drawings in the description include: a main body 1 , a accommodating part 2 , a positioning part 3 , a passing through hole 4 , and a limiting plate 5 .

Detailed ways

In order to make the technical means, creative features, achievement goals and functions realized by the present utility model clearer and easier to understand, the present utility model is further elaborated below in conjunction with the accompanying drawings and specific embodiments:

As shown in FIG. 1 , the present utility model discloses a side wall drilling fixture for cylindrical parts, comprising a fixture body 1 with a flat bottom surface. The body 1 is provided with accommodating holes for accommodating parts along the horizontal direction. The body 1 The top surface is provided with a passing through hole 4 for the drill bit to pass vertically through the receiving hole, and one end of the receiving hole is provided with a limiting plate 5 perpendicular to the center line of the receiving hole.

When in use, just place the through hole 4 of the fixture facing the drill bit, fix the fixture, insert the part into the accommodating hole, clamp it with the limit plate 5, press down the drill bit through the through hole 4 The parts are drilled to meet the processing requirements. Because the common radial drilling machine can be used, the cost is low, the fixture structure is simple, the loading and unloading is convenient, and the processing efficiency is significantly improved.

Preferably, the accommodating hole includes an upper accommodating part 2 and a lower locating part 3, the accommodating part 2 has a space for accommodating all the parts to be drilled into, and the locating part is gradually symmetrical from top to bottom. receive. The symmetrical structure of the limit part makes the parts inserted into the accommodating hole due to the action of gravity, and at the same time, under the symmetrical restrictions on both sides of the limit part, it is ensured that the center axis of the part intersects with the center axis of the through hole 4, thus further ensuring the processing precision.

Preferably, the accommodating portion 2 of the accommodating hole is a cylindrical shape with a diameter slightly larger than that of the component, and the positioning portion 3 is an inverted isosceles triangular column tangent to the cylindrical edge of the accommodating portion.

Preferably, the accommodating hole is a through hole, and the limiting plate 5 is detachably connected to the body 1 . After long-term use, the limit plate 5 may be worn, causing errors in the drilling position. In this case, only a new limit plate 5 can be replaced to solve the problem, and there is no need to replace the fixture as a whole.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should The technical solutions are modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and all of them should be included in the scope of the claims of the present invention.
