Single-cylinder driven dual-pressing-head reinforced clamp self-locking, removal and jacking mechanism

Abstract

The invention discloses a single-cylinder driven dual-pressing-head reinforced clamp self-locking, removal and jacking mechanism which comprises a pressing arm I, a pressing arm II, a connecting plateI and a connecting plate II, wherein the connecting plate II is located on one side of the whole mechanism; the connecting plate I is arranged on one side of the connecting plate II; the pressing armI and the pressing arm II are arranged between the connecting plate II and the connecting plate I. The mechanism is scientific, reasonable, and safe and convenient to use, and solves the problems that a welding gun cannot complete consecutive welding at a time during welding production and local welding quality cannot be guaranteed since a clamping mechanism is large and complicated, and the positioning reliability and positioning strength are reduced since the mechanism is large in size and complicated to result in mutual negative effects when a pin pulling mechanism is matched with the clamping mechanism for use; an appearance of the mechanism adopts a square design; six surfaces can serve as mounting surfaces; the mechanism is flexible in actual use; and an application scope of the mechanism is enlarged.

Description

Technical field [0001] The invention relates to the technical field of tooling, in particular to a single-cylinder-driven double-indenter force-increasing clamping self-locking and simultaneously opening a belt jacking mechanism. Background technique [0002] In the field of tooling, the structure of the positioning and clamping mechanism is usually designed according to the shape and required functions of the workpiece to meet the requirements of positioning, clamping and loading and unloading of the workpiece. For some workpieces, it may need to be carried out in multiple directions at the same time. Clamping is fixed, and the material needs to be initially returned before manual pickup. The structure of the positioning and clamping mechanism is more complicated. For example, in the welding production of the energy absorbing box of the vehicle bumper and the welding process of the energy absorbing box, it is necessary before welding. Use the positioning clamping mechanism to po...

Problems solved by technology

[0002] In the field of tooling, the structural form of the positioning and clamping mechanism is usually designed according to the shape and required functions of the workpiece to meet the positioning, clamping and loading and unloading requirements of the workpiece. Clamping and fixing, and preliminary material return before manual pick-up, the structure of the positioning and clamping mechanism is more complicated. For example, in the welding production of vehicle bumper crash boxes and the welding process of crash boxes, before welding, it is necessary Use the positioning and clamping mechanism to position the energy-absorbing box. The positioning method is generally to make a fixed support structure and a movable pin pull mechanism under the energy-absorbing box, and then make two clamping mechanisms on both sides for positioning. Since the energy-absorbing box needs to be There are weld seams in welding, and the welding deformation is severe. In order to ensure the welding accuracy, the positioning mechanism needs to be reliable enough, which leads to a very cumbersome and bulky mechanism, which often affects the accessibility of the welding torch during welding, so that a few places are not welded in place or the welding quality is not good. In addition, because the bumper assembly is long, and the energy-absorbing box is at both ends and the welding seam is concentrated and deformed, it is very difficult for workers to pick up the parts after welding. The conventional solution is to make a movable pin pull mechanism under the energy-absorbing box This will make the positioning structure of the energy-absorbing box particularly cumbersome and cumbersome, and also increase the weight of the fixture, which will have a certain impact on the load and service life of the positioner, and also negatively affect the positioning reliability of the clamping mechanisms on both sides , because it takes up part of the space, the design space of the clamping mechanism is smaller, and its positioning reliability and strength level are reduced.
