Abstract

The utility model provides a motor vehicle skylight glass framework based on tool positioning. The motor vehicle skylight glass framework comprises a front framework, a rear framework, a middle transverse beam and a guide rail, wherein positioning pins of workpieces at the two ends of the guide rail are used for positioning and replacing cylinder positioning of the front framework and the rear framework so as to control the dimensional tolerance in the X direction; the dimensional tolerance in the Y direction is controlled through a first positioning groove in the center of the front framework; the position degree tolerance of a chain pipe hole of the rear framework is controlled through a second positioning groove in the center of the rear framework. According to the motor vehicle skylight glass framework based on the tool positioning provided by the utility model, the dimensional tolerance in the X direction and the dimensional tolerance in the Y direction of the skylight glass framework are reduced; meanwhile, the position degree tolerance of the chain pipe hole of a skylight is reduced.

Description

Self-propelled vehicle skylight glass framework based on tool locating

Technical field

The utility model relates to self-propelled vehicle skylight assembly technical field, relates in particular to the self-propelled vehicle skylight glass framework based on tool locating.

Background technology

In prior art, the dimensional control of self-propelled vehicle skylight glass framework is to realize by the feature on part, concrete, the dimension limit of the cylinder control directions X (see figure 1) based on front baffle and rear frame; The dimension limit of the groove control Y-direction (see figure 1) based on guide rail, this groove can allow front frame to have certain amount of movement in Y-direction, confines position inaccurate before causing; In the position degree control of the Y-direction of after-frame chain pore, wherein the Y-direction position degree of a side is determined by the registration mast of opposite side, and because this size span is very large, causes tolerance very large.

Utility model content

The purpose of this utility model is to provide a kind of self-propelled vehicle skylight glass framework based on tool locating, reduces the dimension limit of skylight glass framework directions X and Y-direction, and reduces the Tolerance of Degree of position of skylight chain pore.

To achieve these goals, the utility model adopts following technical scheme:

A self-propelled vehicle skylight glass framework based on tool locating, comprises front baffle, rear frame, center member and guide rail, replaces the cylinder of front baffle and rear frame to locate to control the dimension limit of directions X by the locating dowel pin location of described guide rail two ends frock; Control the dimension limit of Y-direction by first positioning groove at described front baffle center; Control the Tolerance of Degree of position of rear frame chain pore by second positioning groove at described rear frame center.

The self-propelled vehicle skylight glass framework of the utility model based on tool locating, controls the dimension limit of directions X by the locating dowel pin of guide rail two ends frock, and the tolerance of locating dowel pin is much smaller than the tolerance with part feature location, has therefore reduced the dimension limit of directions X; Control the dimension limit of Y-direction by first positioning groove at described front baffle center, can make leading dimensions tolerance mean allocation to both sides, and there is no the movement of Y-direction, therefore reduced the dimension limit of Y-direction; Control the Tolerance of Degree of position of rear frame chain pore by second positioning groove at described rear frame center, can make the position degree mean allocation of the driving tube of both sides or the Y-direction of plastics guiding pore to both sides, and because size span reduces half, can make this Tolerance of Degree of position be reduced to the half of prior art, therefore reduce the Tolerance of Degree of position of skylight chain pore.

Brief description of the drawings

Fig. 1 is the structural representation of the self-propelled vehicle skylight glass framework of the utility model based on tool locating.

Detailed description of the invention

Below in conjunction with brief description of the drawings detailed description of the invention of the present utility model.

As shown in Figure 1, a kind of self-propelled vehicle skylight glass framework based on tool locating, comprise front baffle 1, rear frame 2, center member 3 and guide rail 4, replace the cylinder of front baffle 1 and rear frame 2 to locate to control the dimension limit of directions X by locating dowel pin 5 location of described guide rail 4 two ends frocks; Control the dimension limit of Y-direction by first positioning groove 6 at described front baffle 1 center; Control the Tolerance of Degree of position of rear frame chain pore 8 by second positioning groove 7 at described rear frame 2 centers.

The self-propelled vehicle skylight glass framework of the utility model based on tool locating, control the dimension limit of directions X by the locating dowel pin 5 of guide rail 4 two ends frocks, and the tolerance of locating dowel pin 5 is much smaller than the tolerance with part feature location, therefore reduce the dimension limit of directions X; Control the dimension limit of Y-direction by first positioning groove 6 at described front baffle 1 center, can make leading dimensions tolerance mean allocation to both sides, and there is no the movement of Y-direction, therefore reduced the dimension limit of Y-direction; Control the Tolerance of Degree of position of rear frame chain pore 8 by second positioning groove 7 at described rear frame 2 centers, can make the position degree mean allocation of the driving tube of both sides or the Y-direction of plastics guiding pore to both sides, and because size span reduces half, can make this Tolerance of Degree of position be reduced to the half of prior art, therefore reduce the Tolerance of Degree of position of skylight chain pore 8.

More than that better enforcement of the present utility model is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and the distortion that these are equal to or replacement are all included in the application's claim limited range.

Claims

1. the self-propelled vehicle skylight glass framework based on tool locating, comprise front baffle, rear frame, center member and guide rail, it is characterized in that: the locating dowel pin location by described guide rail two ends frock replaces the cylinder of described front baffle and described rear frame to locate to control the dimension limit of directions X; Control the dimension limit of Y-direction by first positioning groove at described front baffle center; Control the Tolerance of Degree of position of rear frame chain pore by second positioning groove at described rear frame center.
