Description

Technical Field

[0001] This utility model belongs to the technical field of part positioning, and specifically relates to a positioning device for parts after laser cutting. Background Art

[0002] A part positioning device is a device used to determine the required position of a part or a machining tool in a specific space. Such a device plays a crucial role in many fields and is an important concept in mechanical engineering. It can be divided into various types according to different application scenarios and requirements. Among them, mechanical positioning is achieved by the mutual cooperation of mechanical parts or devices. Common mechanical positioning methods include pin positioning, wedge positioning, snap positioning, and spring positioning, etc. These methods mainly achieve accurate positioning of parts at specific positions through the contact and restriction of mechanical parts.

[0003] For workpiece positioning in mechanical processing and the like, it is now common to drive the corresponding positioning parts to move in two different directions through two different driving parts respectively, so that the two positioning parts hold the workpiece against two reference surfaces. However, the linkage requirements of the two driving parts are high, and it often occurs that after the positioning part and the reference surface fix the workpiece in one direction, it is difficult for the workpiece to move in the other direction, resulting in inaccurate part positioning and affecting the subsequent camera imaging verification work. Content of the Utility Model

[0004] The purpose of this utility model is to provide a positioning device for parts after laser cutting, which can limit three sides of the part, so that the part is limited and positioned within a limited range, and is helpful for the subsequent verification work of industrial camera imaging.

[0026] See also Figures 2-3A small rotating wheel 5 is provided at the top of the U-shaped bracket 3 corresponding to the position of the supporting legs at both ends. A first motor 7 is provided at the bottom of the small rotating wheel 5 at one end. The two small rotating wheels 5 are covered with a first pulley 6. The rotating wheel 5 is driven by the first motor 7 to make the first pulley 6 move. A first clamping seat 9 is installed on the first pulley 6, and one side of the first clamping seat 9 is fixed to the first guide block 8.

[0027] According to the above structure, when the first motor 7 drives the small pulley 5 to move, the small pulley 5 drives the first pulley 6 to move, and the first holder 9 installed on the first pulley 6 will move together with the moving path of the first pulley 6, and the positioning rod 10 installed at the bottom of the first guide block 8 fixed to the first pulley 6 also moves back and forth. When the positioning rod 10 reciprocates, the positioning paddle 11 adjusts the surface of the part to be flat on the conveyor belt 1. The positioning paddle 11 is close to the surface of the part, and the placement position of the part is preliminarily determined, thereby improving the accuracy of subsequent industrial camera photography.

[0028] See also Figures 3-4 A second rail 12 is provided between the two mounting frames 2, and a second guide block 17 is slidably connected to the second rail 12.

A cylinder 19 is installed on the L-shaped connecting plate 16 below the second clamping seat 18, and a limit plate 20 is fixed at the position of the telescopic end at the bottom end of the cylinder 19.

[0029] Based on the above structure, the first guide block 8 linked to the first rail 4 is the upper positioning structure, and the second holder 18 linked to the second rail 12 is the lower positioning structure. The operating principle of the upper positioning structure is consistent with that of the lower positioning structure. The difference is that a cylinder 19 is also installed on the L-shaped connecting plate 16, and the limit plate 20 at the telescopic end of the bottom end of the cylinder 19 can limit the position range of the part on the conveyor belt 1.
