Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of methods and apparatus consistent with certain aspects of the present application, as detailed in the appended claims.

As shown in fig. 1, an exemplary embodiment shows a fixture for positioning and milling an automobile door handle, which includes a fixture body 1, two sets of positioning holes 2 are formed in the fixture body 1 in an axial direction, the two sets of positioning holes 2 are arranged in a left-right symmetry manner to process the automobile door handle with a symmetrical shape, and a step of manufacturing a symmetrical fixture is omitted. The positioning row holes 2 comprise a plurality of positioning holes 21, a user can select and use a proper positioning hole 21 to position and fix the door handle according to the size of the door handle, corresponding fixtures do not need to be designed for different door handles, and a large amount of time is avoided being spent on the design and processing of the fixtures, so that the universality is high. In addition, in some embodiments, the positioning hole 21 may be replaced with or combined with a bolt connecting through hole to fix the door handle according to the shape characteristics of the processed door handle.

As shown in fig. 2 and 3, in some embodiments, an anti-inversion structure 3 is provided adjacent to at least one of the positioning row holes 2 to prevent the symmetrically arranged door handles of the vehicle from being inverted. The anti-reverse structure 3 comprises two limiting columns 31 symmetrically arranged with the positioning row holes 2.

In actual work, need program according to door handle data and anchor clamps data before processing to the door handle, compare with prior art, this application is the axisymmetric structure, and has designed two and has avoided the anti-spacing post 31 of putting of automobile door handle. When the symmetrical vehicle door handle is machined, a programmer can directly carry out symmetrical processing on the clamp in data, the obtained symmetrical structure is consistent with the clamp body 1, and accurate and reliable positioning of a symmetrical workpiece can be guaranteed.

As shown in fig. 1 and 4, in some embodiments, the fixture body 1 is further provided with a cork positioning hole 4, and the cork positioning hole 4 is disposed on the opposite surface of the positioning row hole 2 to match with a cork positioning system of the workbench.

Because for the operating condition of assembly line when door handle adds man-hour, anchor clamps need bear the wearing and tearing that periodic dismantlement installation process brought, consequently in some embodiments, each downthehole round pin 22 that still is equipped with the connection of dismantling of location round hole 2 to reinforcing this application stand wear and tear ability and precision, in addition, round pin 22 is easily changed, has avoided the too early elimination of anchor clamps, has prolonged life. Meanwhile, the bottom of each hole of the positioning row holes 2 is provided with a limiting structure 23 so as to limit the pin sleeve 22 to fall.

As shown in fig. 3 and 4, in some embodiments, the bottom of the fixture body 1 is further provided with nut avoiding structures 24 corresponding to the positioning row holes 2 one to one, where the nut avoiding structures 24 are grooves having a depth greater than the height of the nuts, so as to ensure that the nuts do not affect the flatness of the bottom surface of the fixture body 1 after the door handle is fixed by using the bolts, thereby facilitating processing. Meanwhile, the nut avoiding structure 24 reserves enough operating space to facilitate the rotation of the nut.

In some embodiments, as shown in fig. 2, each positioning row of holes 2 has 4 holes, and the holes are arranged in a line along the length direction of the automobile door handle, so that the door handle structure is suitable for most of the existing automobile door handle structures, and the universality is stronger.
