Description

Technical Field

[0001] This utility model relates to the field of floating unit technology, specifically to an XY direction floating compensation unit based on aerodynamic principles. Background Technology

[0002] Floating units primarily achieve adaptive adjustment through elastic deformation. Their main functions include: adaptive adjustment, where elastic elements such as springs and rubber deform when subjected to external forces or workpiece displacement, allowing the device to float within a ±1-5mm range and automatically adjust its position or angle to maintain stable contact; buffering protection, where elastic elements absorb impact or vibration energy, reducing workpiece deformation or equipment damage caused by rigid impacts and extending service life; pressure distribution, where floating structures disperse pressure in stamping, assembly, and other scenarios, preventing localized overloads such as cracking of electronic components and improving processing accuracy; and simplified installation, where some floating devices can be installed without precise alignment, reducing operational difficulty, such as in electrical connection scenarios for communication equipment or industrial equipment.

[0003] However, traditional floating cells have the following drawbacks:

[0004] (1) Currently, floating units are mainly divided into floating units based on elastic elements, floating units based on pneumatic or hydraulic propulsion, and floating units based on the principle of guide rail sliders. Floating units based on elastic elements have a stable structure and can buffer vibration and impact, but the positioning accuracy is low and they are not suitable for rigid connections. In heavy load or anti-torsion scenarios, deformation occurs, which reduces stability.

[0005] (2) The floating principle based on guide rails and sliders is achieved through the cooperation of cross guide rails and sliders. It has high precision, but also high cost and difficult assembly. Utility Model Content

Currently, floating units are mainly divided into floating units based on elastic elements, floating units based on pneumatic or hydraulic propulsion, and floating units based on guide rails and sliders. Floating units based on elastic elements experience deformation, which reduces stability.

During assembly, these requirements must be followed to ensure the normal operation and functional realization of the equipment.

It uses air pressure to control the floating and locking states, and achieves error compensation through precision-machined mechanical structure, meeting the dual requirements of flexibility and precision of the end effector in industrial automation. In practical applications, it is necessary to combine the parameters of the robotic arm control system and adjust the air pressure value and compensation stroke to achieve the best compensation effect.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-5 This utility model provides an XY direction floating compensation unit based on pneumatic principles, including a base plate 1, a lower housing 2 at the top of the base plate 1, a middle housing 3 at the top of the lower housing 2, and an upper housing 4 at the top of the middle housing 3. A piston 6 is fixedly installed inside the lower housing 2, and a sliding block 7 is fixedly installed in the middle of the bottom end of the base plate 1. A magnetic switch unlocked state interface 16 is opened on the surface of the middle housing 3, and a magnetic switch locked state interface 17 is opened on the middle housing 3 below the magnetic switch unlocked state interface 16. The magnetic switch unlocked state interface 16 and the magnetic switch locked state interface 17 indicate that these positions are used for installing magnetic switches, and there are specific requirements for the state of the magnetic switches. During assembly, these requirements must be followed to ensure the normal operation and functional realization of the equipment.

[0023] One end of the middle housing 3 is provided with an A unlocked state interface 13, which is a locking air port.

[0024] A B-locked state interface 14 is provided in the middle of one side of the middle housing 3. The B-locked state interface 14 is a floating air port.

[0025] The other end C of the middle housing 3 stores the position status interface 15. The user only opens the required air interface and seals the unnecessary air interface with a suitable blind plug.

[0026] Both sides of the bottom of the upper housing 4 are fixedly installed with stop posts 5, and both sides of the top of the middle housing 3 are provided with stop grooves 10. The two stop grooves 10 are respectively set with the two stop posts 5. The upper housing 4 is assembled with the middle housing 3 through the stop posts 5 and the stop grooves 10.

[0027] The lower housing 2 has first slots 8 on both sides of the bottom end, and two first posts 9 are fixedly installed in the middle of the top of the base plate 1. The two first slots 8 are respectively set to correspond to the two first posts 9. The lower housing 2 is connected to the base plate 1 through the first slots 8 and the first posts 9.

[0028] A second locking post 12 is fixedly installed on one side of the inner wall of the lower housing 2, and a second locking groove 11 is opened on one side of the bottom end of the middle housing 3. The second locking groove 11 is correspondingly set with the second locking post 12, and the lower housing 2 is connected to the middle housing 3 through the second locking post 12 and the second locking groove 11.

[0029] In this embodiment, the user uses an Allen wrench to fix the product to the end effector of the robot. The cylindrical pin can be used to center the product. The lower housing 2 is connected to the base plate 1 through the first slot 8 and the first pin 9. The lower housing 2 is connected to the middle housing 3 through the second pin 12 and the second slot 11. The upper housing 4 is assembled with the middle housing 3 through the stop pin 5 and the stop groove 10. The user only opens the required air interface. For the unnecessary air interface, a suitable blind plug is used to seal it. The magnetic switch unlocked state interface 16 and the magnetic switch locked state interface 17 indicate that these positions are used to install the magnetic switch and there are specific requirements for the state of the magnetic switch. During assembly, the operation must be carried out according to these requirements to ensure the normal operation and function realization of the equipment.

[0030] With a compensation stroke of ±2.5mm and a repeatability positioning accuracy of 0.1mm, this typically refers to the movable stroke range designed in a mechanical system to compensate for specific displacements, errors, or deformations. Its core function is to offset positional deviations caused by factors such as process flow, temperature changes, and assembly errors through active or passive mechanical / pneumatic / hydraulic means, ensuring system accuracy and stability. With a rated load of 30N, this floating mechanism, through pneumatic drive ports, high-precision dimensional tolerances, and standardized installation interfaces, constructs an XY plane position compensation unit suitable for the end effector of a robotic arm. It utilizes pneumatic pressure to control the floating and locking states and achieves error compensation through a precision-machined mechanical structure, meeting the dual requirements of flexibility and accuracy for end effectors in industrial automation. In practical applications, it is necessary to adjust the pneumatic pressure and compensation stroke in conjunction with the robotic arm control system parameters to achieve the best compensation effect.

[0031] According to the design principle of the mechanism, when the two pistons 6 inside the compensation unit move downward, they push the conical pin to cooperate with the conical hole to achieve zero positioning and lock the position and angle offset. When the pistons 6 are pushed upward, the gap between the conical pin and the conical hole allows the flexible disk and the fixed disk to offset the position and angle.

[0032] The mechanical interface is fixed to the end flange of the robotic arm through 4x M4 screw holes to achieve two-dimensional floating in the XY plane. The air circuit connection lock port and floating port are connected to the pneumatic control system of the robotic arm through air pipes to adjust the compensation force and locking status in real time.

[0033] The locking compensation unit applies pressure to the magnetic switch locking state interface 17 to lock the position storage device, pushes the magnetic switch into the profile groove until it switches; fixes the magnetic switch in this position with the screws on the magnetic switch; and performs unlocking and locking operations on the position storage device.

[0034] Unlock the compensation unit, apply pressure to the unlocked magnetic switch interface 16, unlock the position storage device, push the magnetic switch into the profile groove until it switches, fix the magnetic switch in this position with the screw on the magnetic switch, and perform the unlock and lock operation on the position storage device.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
