High-performance automobile hood transferring gripper structure

Abstract

A high-performance automobile hood transferring gripper structure comprises a bearing frame, a first clamping unit, a first positioning unit, a second clamping unit, a first supporting unit, a third clamping unit, a second positioning unit, a fourth clamping unit, a third positioning unit, a second supporting unit and a fifth clamping unit; and all the units are fixedly connected with the bearingframe through connection pieces. According to the high-performance automobile hood transferring gripper structure, the multiple units are subjected to modularized combining, and each unit is compact in structure, comprehensive in function and high in structural strength; for the clamping positions of a compact space, the clamping and positioning functions of all the units are subjected to integrated treatment, so that a gripper mechanism has the higher functionality; and the units of the gripper mechanism is subjected to angle adjusting, and the gripper structure is suitable for the positioning clamping functions of workpieces different in type and is high in applicability.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a handling handle structure for a high-performance automobile front cover. Background technique [0002] The large-scale production of automobiles in my country is developing rapidly, the market competition is increasingly intensified, and the diversification and individualized development of customers and market demands. Automobile production is transitioning from the traditional single-variety and mass-production mode to multi-species and small-volume production mode. . In order to speed up product launch and reduce project risks, planning a flexible production platform has become the consensus of major car companies. In the process of automobile manufacturing and production, there is a process of assembling various parts of the body shell. The technology currently used has replaced the production form of manual operation with the form of mechanized production line. The...

Problems solved by technology

[0004] (1) The form of the bearing frame used as the gripper mechanism adopts a square tube as a supporting profile, and forms a stable bearing frame structure by connecting the fittings to the adapter, or forms a fixed structure bearing frame structure in the form of direct welding, and the bearing frame The production and assembly process is complicated, the structure is fixed, and the bearing frame cannot be disassembled and replaced

[0005] (2) The clamping unit is fixedly connected with the carrier frame, and the assembly of each clamping unit realizes the clamping of the workpiece, but the parameters such as the position and angle of the clamping unit cannot be flexibly adjusted, and only one type of workpiece structure can be adjusted For clamping, it is not suitable for clamping multiple types of workpieces

[0006] (3) For the positioning points of different positioning units, there are different positioning methods. In the existing structure, there is a structure for limiting the position of the positioning pin, so that the positioning process of the positioning pin is not accurate during the expansion and contraction process. When positioning When the pin fails too much and is inserted into the positioning hole of the car front cover, the positioning unit does not limit the stroke of the positioning pin, so as to achieve the purpose of protecting the function of the car front cover

[0007] (4) The existing clamping units are all connected to the bearing frame through the connecting structure. When strengthening the clamping and fixing of local parts, multiple sets of clamping units are required to clamp at the same time, which increases the manufacturing cost of the gripper mechanism. At the same time, the structural volume of the gripper device is increased at the clamping unit

[0008] (5) In the positioning process of key parts, the control of the stroke distance of the positioning pin is the most important link, but for the positioning structure of complex workpieces, the positioning structure needs to be adjusted, the accuracy of positioning is insufficient, and the stroke of the positioning pin Less accurate distance control

[0009] (6) The clamping process of the existing general technology all works through the cooperation of the clamping unit and the positioning unit, but when there is a narrow operating space or a key processing part, the clamping unit and the positioning unit cannot work alone, and it is necessary to The functions of the two are integrated to form a more compact operating unit
