Description

Positioning device and assembly method thereof

The invention provides a positioning device and an assembling method thereof, in particular, it can be applied to a plate with a thin thickness or at a corner, and the inclined convex surface of the fixture working table is used to make the annular convex body of the positioning element sleeve. When the shape changes, it is fixed on the plate, so that the positioning element and the plate are firmly combined, and the plate will not be deformed or damaged.

Press. When assembling and joining general plates (board-to-board), they are locked by positioning screws with knobs, collars, and screws. The screws and collars are first fixed on the outer panel and rotated first. The knob is used for the screw to lock the inner panel to form a preset position. After the screw is tightened with a hand tool, the outer panel and the inner panel are locked into one body. The locking mode of this multilayer board is It can be used for working machine or other board-to-board connection; however, these working machines need to use the plate to lock the joints. Most of them are power devices or speed adjustment devices. Various power devices and speed adjustment devices are located in Inside the space formed by the implement shell, you can use the plate to assemble, lock, and disassemble. When the power unit is down, malfunctioned, or damaged, or the rate adjustment device is used to change or adjust the rate, the plate is removed. To perform related maintenance and adjustment operations, and the plate is locked by a plurality of positioning screws, so it is easy to cause the positioning screws to fall off and lose during the disassembly process. , You can not re-locking plate back into place, the impact of inconvenience and trouble assembling, dismantling operations.

That is to say, in order to solve the shortcomings of the locking screws that are easy to be lost, some manufacturers have developed a fixing device consisting of a cap, a screw part and a positioning base. The part is locked on another sheet to form a fixing. When the user removes the sheet, the fixing device can still be fixed in the perforation of the sheet through the positioning seat, so that the fixing device does not fall off or be lost.

However, the structural strength at the corners of sheet materials is generally poor, and today's machines, mainframes, etc. are developing to be lighter and thinner, so the sheets are becoming thinner and thinner, so that when the positioning seat is formed on the sheet by riveting, The plate is prone to bending deformation or cracking, which results in the positioning seat cannot be riveted firmly to the plate, and the problem of loosening or detachment may occur, thereby affecting the plate, assembly and disassembly operations.

When the inclined convex surface of the fixture working table is used to process the annular convex body, the annular convex body will be deformed, and The positioning ring body card is fixed at the opposite two side surfaces of the board so as to have vertical and horizontal position-limiting effects and prevent the positioning element from being easily detached from the board, thereby increasing the overall structure and shear resistance The purpose of strength.

The secondary purpose of the present invention is that the pressing surface of the working table is inclined. When the pressing surface is in contact with the annular convex body, the inclined pressing surface can be used to reduce the area of the force to make the annular convex The body is more prone to deformation, which can reduce the pressing force of the clamping block of the jig to prevent the board from being deformed or damaged due to excessive force. This allows the positioning element and the jig to be applied to thinner thicknesses. Or it is located on the board at the corners, so that the purpose of improving the convenience and breadth of the positioning element can be achieved.

Another object of the present invention is that the outer diameter of the locking portion of the fastener is larger than the inner diameter of the limiting convex ring of the perforation. When the positioning element is reversely placed in the die hole of the working table, the perforation limit is limited. The convex ring will stop at the locking portion of the locking member to prevent the locking member from detaching from the perforation of the sleeve, thereby achieving the purpose of improving the smoothness of the assembly operation.
