Description

Technical Field

[0001] The utility model relates to the technical field of industrial automation, in particular to a miniaturized pneumatic friction travel clutch mechanism. Background Art

[0002] With the development of industrial automation, automated handling is becoming more and more popular. However, in some non-standard assembly fields, due to the poor consistency of workpieces and the deviation of surrounding positioning devices, the automated walking mechanism must be made into a disengagement mechanism, and when the friction wheel moves to a specific station, the transmission friction wheel mechanism will automatically drop down, causing the moving friction wheel to be off the track. At a specific station, manual operation is performed to grab the workpiece, and the deviation of the workpiece is corrected by people. After the workpiece is grasped, the friction wheel walking mechanism is then pushed into place by the cylinder, and the friction wheel walking mechanism then drags the handling manipulator to move automatically.

[0003] The traditional friction wheel travel mechanism is an integrated one, with the motor reducer, friction wheel and transmission mechanism integrated together. Through the clutch lifting mechanism, the entire mechanism is lifted and lowered to achieve the clutch of the friction wheel and the travel track. When it is lifted, the friction wheel contacts the track, and the entire equipment realizes automatic travel. The lifting mechanism is lowered, the friction wheel is disengaged from the track, and the entire travel mechanism is lowered to achieve disengagement and manual operation. The overall weight of the traditional friction wheel travel mechanism is 40-50KG. To achieve the smooth implementation of lifting and lowering, the lifting mechanism often uses a large cylinder with a cylinder diameter of 63, so that enough power can be generated to lift the entire travel mechanism into place and realize the contact between the friction wheel and the track. Since one end of the entire friction wheel travel mechanism is fixed on the frame, the design requires an eccentric structure. The 40-50K heavy travel mechanism needs to be lifted as a whole, and the lifting frequency is 1 time / 2 minutes. The entire rotating mechanism is very easy to be damaged, and the requirements for the lifting mechanism are also very high. The lifting mechanism is also a vulnerable part. The traditional friction travel mechanism has a high failure rate, unstable operation, and high maintenance cost.

[0004] In addition, the traditional friction clutch travel mechanism is electrically driven, while the pneumatic lifting mechanism is driven by compressed air. The electric + gas hybrid drive is relatively complicated in actual application, requiring two power sources, compressed air and power supply, which is relatively costly and complicated to install and maintain.

[0020] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0021] A miniaturized pneumatic friction travel clutch mechanism, a pulley 1, a tightening cylinder 2, an air motor 3, a friction wheel 4, a bearing 5, a rotating shaft 6, a coupling 7, an air motor base 8, a bearing cover 9 and a sleeve 10, and a friction wheel housing 11; wherein: the air motor 3 is mounted on the bottom of the air motor base 8 by bolts, and the rotating shaft of the air motor 3 extends into the interior of the air motor base 8; the interior of the air motor base 8 is equipped with a coupling 7, and the rotating shaft of the air motor 3 is connected to the rotating shaft 6 through the coupling 7; the air motor base 8 is provided ... The bottom of the pneumatic motor base 8 is bolted with a friction wheel housing 11, and the top and bottom of the friction wheel housing 11 are both installed with bearings 5. The top of the rotating shaft 6 is installed in the bearing 5 at the top of the friction wheel housing 11, and the bottom of the rotating shaft 6 is installed in the bearing 5 at the bottom of the friction wheel housing 11; the outer sleeve of the rotating shaft 6 is sleeved with a shaft sleeve 10, and the outer sleeve of the shaft sleeve 10 is sleeved with a friction wheel 4. A tightening cylinder 2 is installed on one side of the pneumatic motor base 8; a pulley 1 is installed on one side of the friction wheel housing 11. A bearing cover 9 for sealing is installed on the bearing 5 at the top of the friction wheel housing 11.

[0022] The top of the pulley 1 is hingedly connected to one side of the friction wheel housing 11, the top of the tightening cylinder 2 is hingedly connected to one side of the pneumatic motor base 8, and the bottom of the tightening cylinder 2 is hingedly connected to the top of the pulley 1 through a connecting rod.

[0023] The pulley 1 includes a pulley plate and a plurality of pulley wheels, the pulley wheels are arranged in pairs on both sides, and the pulley wheels are installed on both sides of the pulley plate through bearings, the top of the pulley plate is hingedly connected to one side of the friction wheel housing 11, and the top of the pulley plate is hingedly connected to the bottom of the tightening cylinder 2 through a connecting rod.

[0024] The pneumatic motor 3 of the friction wheel travel mechanism is connected to the friction wheel 4 through the bearing 5, the rotating shaft 6 and the coupling 7. Due to the use of a micro pneumatic motor, the entire friction travel mechanism is more compact, small and light compared to the original electric drive. The jacking cylinder 2 only needs to push the 15KG pneumatic friction travel mechanism, which greatly improves the lifting efficiency, and the entire mechanism is pneumatically driven, which greatly improves efficiency and cost.

[0025] The friction wheel travel mechanism, micro pneumatic motor + reducer mechanism, has a small motor weight and high power. The entire volume is one-fourth of the original electric motor friction travel mechanism. The pneumatic motor + reducer + friction wheel are integrated on a rotating shaft 6. The total mass of the entire pneumatic friction travel mechanism is 15KG, while the mass of the original electric friction travel mechanism is about 50KG. With its light volume and compact structure, the lifting cylinder lifts the 15KG pneumatic friction travel mechanism, which greatly reduces the load compared to the entire mechanism that lifts the 40-50KG weight of the electric friction mechanism. And the lifting time can reach 0.5 seconds, which is much better than the original 1-2 seconds, and the transmission efficiency is greatly improved. The weight of the mechanism that is frequently lifted is greatly reduced, and the load of the lifting mechanism is greatly reduced.

[0026] The traditional electric motor drive has been updated to a pneumatic motor mechanism. The entire friction walking mechanism only requires a 5Bar compressed air pipeline. Compared with the traditional electric + compressed air hybrid drive, the installation and maintenance costs are also greatly reduced.

[0027] The stability of the friction travel mechanism has been greatly improved, and the life of the lifting mechanism has been extended from half a year to more than 2 years. The new friction travel mechanism has greatly improved efficiency, extended the maintenance interval, and reduced maintenance costs. The social benefits are significant.
