Embodiment Construction

[0008] The specific implementation manner of the present invention will be described below with reference to the accompanying drawings. Such as figure 1 Shown: a backstop device, the device includes a bracket 1, a pin 2 is arranged on the bracket 1, the pin 2 is matched with the arc-shaped opening 4 on the swing crank 3, and can slide in the arc-shaped opening 4 , and the pin shaft 2 and the swing crank 3 are two sets, symmetrically arranged on both sides of the bracket 1.

[0009] The working process of the anti-retraction device in the embodiment of the present invention is as follows: the bracket 1 of the device is fixedly arranged in the way of workpiece transportation, the swing cranks 3 on both sides of the bracket 1 naturally droop under the action of their own weight, and their lower edges protrude With the outer contour of the bracket 1, the workpiece moves to the bottom of the bracket 1 under the action of the conveyor belt, and the workpiece will push up the lower ...

Abstract

The invention discloses a retaining device. The retaining device is characterized by comprising a support (1), pin shafts (2) are arranged on the support (1), the pin shafts (2) are arranged inside arc-shaped openings (4) which are formed in swing cranks (3), and the two sets of the pin shafts (2) and the swing cranks (3) are arranged symmetrically on two sides of the support (1). The retaining device is simple in structure, ingenious in design, and capable of using a simple dead weigh and crank mechanism to prevent a workpiece from moving reversely.

Description

technical field [0001] The invention relates to a position-limiting device, in particular to a back-stopping device for preventing reverse movement of workpieces. Background technique [0002] Buffer, roller bed and other conveying equipment are one of the necessary equipment for the automobile welding line. Due to the high requirements for its running stability and running precision, it is necessary to ensure high precision at the stop position. In the automobile welding production line, due to the high automation rate, the conveying device is required to have high accuracy. Traditionally, the detection switch is combined with the pneumatic clamping cylinder to ensure accurate positioning. However, this positioning device has high requirements in terms of cost, space, control, etc., and will bring high operating costs to the enterprise. Therefore, there is a need for a device or structure capable of solving the above-mentioned problems. Contents of the invention [0003...
