Embodiment Construction

[0021] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] see Figure 1-4 , a pneumatic clamping mechanism for automobile body welding, which includes a pressing unit 1, a hinged plate 2, a cylinder rotation limiter 3, a cylinder 4, a connecting plate 5, a support 6, and a positioning block 7, wherein the hinged plate and The connection plate is hinged, the positioning block is fixed on the connection plate, and the connection plate is fixed on the support; the cylinder is connected to the compression unit. When working, the workpiece is clamped between the positioning block and the compression unit. A cylinder rotation limiter 3 is arranged between them, and the cylinder rotation limiter is fixedly connected to the connecting plate; the pressing unit is hinged to the hinge plate. The cylinder rotation limiter is L-shaped, one end of which is fixed on the upper end of the cylinder block, and the other e...

Abstract

The invention relates to a pneumatic clamp pressing mechanism for automotive body welding, comprising a pressing unit, a hinge plate, a cylinder rotation limiter, a cylinder, a connecting plate, a support and a locating block. The hinge plate is hinged with the connecting plate, and the locating piece is fixedly connected on the connecting plate which is fixedly connected on the support; the cylinder is connected with the pressing unit, when the pneumatic clamp pressing mechanism for automotive body welding works, a workpiece is clamped between the locating block and the pressing unit, and the cylinder rotation limiter is arranged between the connecting plate and the cylinder and fixedly connected on the connecting plate; and the pressing unit is hinged with the hinge plate. According to the pneumatic clamp pressing mechanism for automotive body welding, the one clamp pressing unit can clamp more than two planes capable of forming a certain angle with each other, so that the arrangement of the more clamp units is avoided, the cost is saved, simultaneously, a larger welding space is provided for the welding production line, and the process feasibility and the operating convenience can be enhanced.

Description

technical field [0001] The invention relates to a compression structure of a pneumatic clamp, in particular to a compression mechanism of a pneumatic clamp for automobile body welding. Background technique [0002] In the body welding production process of the automobile manufacturing plant, the welding fixtures on the welding production line are mostly pneumatic fixtures, so as to ensure the accurate positioning and effective clamping of the workpiece by the fixture. Usually, the same clamp pressing unit (the pressing unit derived from a pneumatic unit and its connecting mechanism are taken as a whole and called a clamp pressing unit, which may contain one or more pressing blocks, such as figure 1 In the clamping unit 1, it contains two clamping blocks) only has the function of clamping one surface of the workpiece. In the fixture design process, the main rotation center of each motion unit ( image 3 The selection of 11 and the lower rotation center of the hinge plate 2) ...
