Description

A positioning drilling fixture

Technical Field

The present application relates to the technical field of parts processing, and in particular to a positioning drilling fixture.

Background technique

In the automobile market, manufacturers set different configurations for the same model to meet the needs of different consumers for automobile products. For example, for the front bumper of a car, a high-configuration bumper of the same model can be equipped with a front vehicle radar or camera, while a low-configuration bumper has nothing. For the bumper, when assembling a radar or camera, there must be mounting holes on the bumper product to meet the installation requirements. Therefore, the same bumper product has two states: with holes and without holes.

In the prior art, in order to meet the needs of a product in two different states (with or without holes), there are two methods: the first method is to develop a mold for each state of the product, develop a mold for the product without the need for mounting holes, and the produced product has no mounting holes; a mold is also developed for the product with the need for mounting holes, and the mold with mounting holes is directly formed by the mold, but this method requires the development of an additional mold, and the production cost of the product is high; the second method is to develop only a mold with mounting holes, and then develop a mounting hole plugging mold. When the corresponding product has the need for mounting holes, it can be directly produced by the mold; when the corresponding product has no need for mounting holes, the mounting hole of the product can be plugged with a plugging cover. Compared with the first method, the second method will save the development cost of a bumper mold in terms of mold development cost, but it still needs to develop a small plugging mold. Both of the above methods require the use of molds for products with mounting holes. However, during the production of molds for products with mounting holes, the risk of injection defects (welding marks, air marks) will be brought due to the presence of mounting holes, and defects cannot be avoided.

Utility Model Content

In view of the above shortcomings of the prior art, the purpose of this application is to provide a positioning drilling fixture to solve the problem that molds for products with mounting holes in the prior art have injection molding defects during production and cannot avoid defects.

In order to achieve the above-mentioned purpose and other related purposes, the present application provides a positioning drilling fixture, which includes:

A support assembly, used to support and position the product;

Positioning components, used for drilling and positioning products;

The support assembly comprises a support base, on which a support block for supporting a drilling portion of the product and a positioning groove for positioning are arranged, the support blocks are symmetrically distributed, and the positioning groove is arranged between the support blocks;

The positioning assembly includes two symmetrically arranged positioning bases, the positioning base includes a first positioning base and a second positioning base, the first positioning base and the second positioning base are connected by a connecting piece, the first positioning base is provided with a first positioning pin for positioning, the bottom of the first positioning base is provided with a first positioning surface conforming to the product structure, the first positioning base is also provided with a first positioning hole for drilling positioning, the second positioning base is provided with a second positioning pin for positioning, the bottom of the second positioning base is provided with a second positioning surface conforming to the product structure, the second positioning base is provided with a second positioning hole for drilling positioning and a mounting hole for positioning.

It is worth noting that, in this embodiment, the product 27 here refers to a car bumper. The bumper product 27 has a non-hole state and a hole state. The first positioning surface 12 and the second positioning surface 16 follow the shape of the product 27 structure, such as the BOSS column, the clamping angle and other structures, and can be changed according to the actual structure of the bumper product 27. The first positioning surface 12 and the second positioning surface 16 are fitted with the product 27 to perform structural positioning, thereby ensuring that the first positioning hole 2 and the second positioning hole 8 coincide with the drilling position of the product 27. The structural changes of the product 27 itself do not affect the implementation of this solution, so there are no excessive restrictions on the specific structure of the product 27.

In this embodiment, please refer to Figures 1 and 2. One end of the first positioning seat 1 is an inclined end 4, and the other end extends vertically in the vertical direction to form an extended end 28. The extended end 28 is connected to the second positioning seat 9. A first positioning pin 3 is provided on the inclined end 4, and a first positioning surface 12 is provided at the bottom of the inclined end 4.
