Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a floating mechanism. Background Technology

[0002] On automated production lines, robotic arms, conveyors, or other actuators need to precisely mount, insert, or press one workpiece onto another stationary workpiece. However, due to manufacturing tolerances, positioning errors, cumulative errors, or equipment wear, there is always a slight deviation in the relative positions of workpiece A and workpiece B (e.g., a few tenths of a millimeter offset in the X and Y directions).

[0003] However, if a completely rigid fixture or connector is used, such a small deviation can cause the workpiece to collide with another workpiece in a tilted or offset posture, resulting in jamming, scratching, and inability to assemble. Even if assembly is barely successful, the connection part will generate huge internal stress, which may cause workpiece deformation or damage, or greatly reduce product life and reliability. Furthermore, excessive interference force will have a reaction effect on expensive robotic arms or actuators, causing them to overload alarm, decrease in accuracy, or even mechanical damage. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a floating mechanism.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A floating mechanism includes: a mounting cover, a positioning cover, a floating cross disc, a transverse sliding plate, a transverse return spring pin, a transverse slide block, a longitudinal sliding plate, a longitudinal return spring pin, and a longitudinal slide block. The mounting cover and the positioning cover are fixedly connected. The floating cross disc is disposed inside the mounting cover. The transverse sliding plate is fixedly mounted on the upper side of the floating cross disc. The transverse slide block is fixedly mounted inside the positioning cover and is slidably connected to the transverse slide block. The longitudinal sliding plate is fixedly mounted on the lower side of the floating cross disc. The longitudinal slide block is fixedly mounted inside the mounting cover and is slidably connected to the longitudinal slide block. The transverse return spring pin is disposed on the mounting cover and cooperates with the transverse ends of the floating cross disc. The longitudinal return spring pin is disposed on the positioning cover and cooperates with the longitudinal ends of the floating cross disc.

[0007] Preferably, the mounting cover is provided with a first deep groove, and shallow grooves are provided on both sides of the first deep groove. The longitudinal slide is fixedly installed in the first deep groove, and the shallow groove is provided with screw mounting holes and a first spring pin mounting hole. The mounting cover is fixedly connected to the mounting reference surface through the screw mounting holes, and the transverse reset spring pin is fixedly connected to the first spring pin mounting hole.

[0008] Preferably, the positioning cover is provided with a second deep groove, and second spring pin mounting holes are provided on both sides of the second deep groove. The transverse slide is fixedly installed in the second deep groove, and the longitudinal reset spring pin is fixedly connected to the second spring pin mounting holes.

[0009] Preferably, the floating cross disc includes: a mounting part and a flange part, the mounting part and the flange part are an integral structure, the flange part is provided with four sets, adjacent flange parts are arranged perpendicularly to each other on the outside of the mounting part, the upper side of the mounting part is fixedly connected to the longitudinal sliding plate, the lower side of the mounting part is fixedly connected to the transverse sliding plate, and the outer side of the flange part is provided with a groove for cooperating with the transverse return spring pin and the longitudinal return spring pin.

[0010] Preferably, the transverse sliding plate has the same structure as the longitudinal sliding plate, the transverse return spring pin has the same structure as the longitudinal return spring pin, and the transverse slide block has the same structure as the longitudinal slide block.

[0011] Preferably, the transverse slide includes a fixed block and a convex ball slide plate, the convex ball slide plate being fixedly connected to the fixed block, and the fixed block being slidably connected to the outer side of the transverse sliding plate through a groove provided by the convex ball slide plate.

[0012] Preferably, the upper part of the pin portion of the transverse reset spring pin is a hemisphere, and the lower part is a cone with a narrow opening at the bottom and a wide opening at the top.

[0013] The advantages of this invention are as follows: By installing this floating mechanism between the actuator (such as the end of a robotic arm) and the workpiece, when one workpiece approaches another, even if there is a positional deviation, the floating cross disc will automatically yield, sliding along the X or Y direction to absorb the deviation. This allows the workpiece to flexibly and stress-free find the correct relative position with another workpiece, achieving smooth assembly or connection. It reduces costs, allowing the use of robotic arms and conveyors with ordinary precision, eliminating the need to upgrade to expensive ultra-high precision equipment. It improves efficiency, reduces downtime, alarms, and manual intervention time caused by inaccurate positioning, enhances the cycle time and automation level of the production line, strengthens robustness, and increases the system's tolerance to interference factors such as incoming material tolerances and equipment vibration, resulting in more stable and reliable operation.
