Description

Rotary positioning device and its rotating mechanism

The present invention provides a rotary positioning device, especially a positioning device that positions or separates two preset plates in a rotational manner. The base is fixed on the preset first plate, and a fixed base is installed and assembled on the preset first plate. On the second plate, the rotating part, the fixed base and the preset second plate are assembled on the base on the preset first plate to achieve the purpose of blocking or separating the rotation and the base.

According to general principles, when assembling and joining panels (board to panel), they are locked using positioning screws with knobs, collars and screws. The screws and collars are first fixed on the outer panel and then rotated. The knob allows the screws to be locked into the inner panel to form a preset position. After the screws are locked with hand tools, the outer panel and the inner panel are locked and integrated into one. The locking mode of this multi-layer panel is It can be used for work machines or other plates connected by plate to plate; however, these work machines need to use plates for locking joints, most of which are power devices or speed adjustment devices, and various power devices and speed adjustment devices are located at Inside the space formed by the machine tool shell, the plates can be assembled, locked, and disassembled. When the power device crashes, malfunctions, or is damaged, or when the speed adjustment device changes or adjusts the speed, the plates can be removed. To carry out related maintenance and adjustment operations, and the plate is locked through a plurality of positioning screws, so the positioning screws may easily fall off or be lost during the disassembly process, and the plate cannot be locked back to its original position, affecting assembly and disassembly. To solve the inconvenience and trouble of work, some operators try to solve the problem of locking screws. Due to the shortcoming of easy loss, a fixing device composed of a cap, a screw part and a positioning base was developed. The positioning base of the fixing device is first fastened into the perforation of the plate, and then the screw part is locked to another plate. It is fixed, and when the user removes the board, the fixing device can still be fixed in the perforation of the board through the positioning seat, so that the fixing device will not fall off or be lost. However, the user must still apply force or operate during the assembly process. Using hand tools (such as screwdrivers or wrenches, etc.) to control the locking or disassembly of fixtures still has many shortcomings and problems in practical applications.

In addition, when two opposite plates are combined by locking and fixing, under the current requirements of modularized mass production and processing efficiency, the tedious manual assembly process using screws will seriously affect the manufacturer's shipment progress. , and the screws are easy to be lost during the process of locking the two plates due to their small size, and may cause problems during assembly, alignment or locking due to the difference in the size of the screw holes at the screw locking positions or the discrepancy in the number of teeth and pitch of the screw holes. It is difficult, and the space between the two opposite plates for operating screws is quite narrow. That is, the screws are easily blocked by surrounding objects when assembling and disassembling the screws. Not only is it quite time-consuming and inconvenient, but it will also cause overall damage. Increased costs will increase the burden on businesses.

Therefore, how to solve the problems and troubles of the current fixing devices used in plate locking, which are easy to be loosened and detached due to incorrect rotation, and the fixing device requires force or the use of hand tools when assembling, is the trouble and inconvenience. Relevant manufacturers engaged in this industry are eager to study the direction of improvement.
