Description

A quick positioning structure for steering gear ECU housing

Technical Field

The utility model relates to the technical field of steering systems, in particular to a quick positioning structure for a steering machine ECU housing.

Background Art

During the assembly process of the steering gear ECU housing, there are certain shape and position deviations in the plastic injection molding box of the housing. In order to meet the precise positioning requirements of the subsequent processing and assembly procedures, the robot will first grab the housing from the material box and place it on a pre-positioning tool for initial positioning, and then grab the housing from the pre-positioning tool and place it on the precision positioning tray for subsequent processes. This makes the robot's operating path long and complicated, resulting in a waste of beats.

Summary of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a quick positioning structure for a steering gear ECU housing, optimizes the shape structure of a precision positioning tray so that it can be compatible with the shape and position deviation of an injection molded plastic box, and completes the precise positioning of housing parts, thereby ultimately reducing the production cycle.

Now the robot can directly place the material from the material box onto the precision positioning pallet, eliminating the path for the robot to run to the pre-positioning tooling and reducing the cycle time of the entire station.

In order to achieve the above-mentioned purpose, a quick positioning structure for the steering gear ECU housing is designed, including a tray and a turntable guide rod, and its characteristics are: the turntable guide rods are respectively connected to the bottom of the tray, and a pre-positioning structure is provided in the center of the tray, and the pre-positioning structure is a circular ring structure; a plurality of housing positioning pins are provided on the inner side of the pre-positioning structure; and clamping claw guide blocks are respectively provided on the left and right sides of the pre-positioning structure.

The pre-positioning structure is composed of three arc-shaped bosses, both ends of the arc-shaped bosses are slope-shaped structures, a rectangular groove is arranged in the middle of the arc-shaped bosses, and a circular arc-shaped groove is arranged inside the rectangular groove.

The gap formed by two adjacent arc-shaped bosses is a pre-positioning guide area.

One side of the arc-shaped boss is a block-shaped boss structure, and the other side of the arc-shaped boss is an L-shaped boss structure.

The tray is a rectangular structure.

There are at least two housing positioning pins, and the housing positioning pins are embedded in the L-shaped boss structure of the pre-positioning structure.

The clamping jaw guide block is provided with a guide hole, and the clamping jaw guide block is connected with the guide pin of the manipulator through the guide hole.

Compared with the prior art, the utility model provides a quick positioning structure for a steering gear ECU housing, optimizes the shape structure of a precision positioning tray, makes it compatible with the shape and position deviation of an injection molding box, and completes the precise positioning of housing parts, thereby ultimately reducing the production cycle.

DETAILED DESCRIPTION

The utility model is further described below with reference to the accompanying drawings.

As shown in Figures 1 and 2, turntable guide rods 5 are connected to the bottom of the tray 1 on all sides, and a pre-positioning structure 3 is provided in the center of the tray 1. The pre-positioning structure 3 is a circular ring structure; a number of shell positioning pins 2 are provided on the inner side of the pre-positioning structure 3; and clamping claw guide blocks 4 are provided on the left and right sides of the pre-positioning structure 3.

The pre-positioning structure 3 is composed of three arc-shaped bosses 3-1. The two ends of the arc-shaped boss 3-1 are sloped structures. A rectangular groove 3-2 is provided in the middle of the arc-shaped boss 3-1, and a circular arc-shaped groove 3-2 is provided inside the rectangular groove 3-2.

The gap formed by two adjacent arc-shaped bosses 3 - 1 is a pre-positioning guide area 3 - 4 .

One side of the arc-shaped boss 3 - 1 is a block-shaped boss structure, and the other side of the arc-shaped boss 3 - 1 is an L-shaped boss structure.

The tray 1 is a rectangular structure.

At least two housing positioning pins 2 are provided, and the housing positioning pins 2 are embedded in the L-shaped boss structure of the pre-positioning structure 3 .

A guide hole 4 - 1 is provided on the clamping jaw guide block 4 , and the clamping jaw guide block 4 is connected with a guide pin of the manipulator through the guide hole 4 - 1 .

As shown in Figure 1, the pallet 1 is positioned by the turntable guide rod 5 and the processing turntable, and the clamp guide block 4 thereon is used for guiding and positioning of the manipulator. As shown in Figure 2, the three circled structures of the pre-positioning structure 3 (i.e., the pre-positioning guide area 3-4) play a major pre-positioning role. When placing the shell parts, as shown in Figure 3, the three plastic columns under the shell will be guided by the smooth large chamfer on the gap and then inserted into the gap to correct the position deviation of the material in the material box and perform initial positioning of the shell. When the manipulator grabs the shell material and places it 5mm above the pallet, it will release the material. During the free fall of the shell, after the pre-positioning structure 3 corrects the position of the shell, the shell positioning pin 2 will be introduced into the process positioning hole of the shell to complete the precise positioning and meet the position requirements of the subsequent processing and assembly process.

Through this structure, the original process of the robot grabbing the material for pre-positioning and then grabbing for precise positioning is combined into one step to meet the assembly positioning requirements, optimize the robot's operation path, and reduce the operation rhythm.

The utility model has a simple structure, is easy to understand, and is easy to implement. It has been successfully applied to the assembly and production of steering gear ECU, and the use results meet the requirements.
