Description

Technical Field

[0001] The present invention relates to the technical field of mechanical automation equipment, and in particular to an anti-stuck cylinder locking positioning mechanism. Background Art

[0002] In industrial automation production environments, especially those involving heavy-duty mold exchange systems, the precise stopping and positioning of the trolley after horizontal movement becomes one of the key factors in ensuring the efficiency and quality of the entire production line. Traditionally, in order to achieve precise positioning of the trolley, the method of motor deceleration and braking is often used. However, when high-precision positioning requirements of 0.5mm level need to be met, this method often cannot meet actual needs. Since it is difficult for the motor control system to stop quickly and accurately within such a fine range after high-speed operation, and under heavy load conditions, the braking torque is limited, it is easy to cause position slippage, thereby affecting the accuracy and stability of positioning. In order to solve this problem, an existing locking positioning mechanism uses a V-shaped positioning pin inserted into a V-shaped positioning plate fixed to the ground or track base to achieve rigid locking, which greatly improves positioning accuracy and stability.

[0003] However, in dusty working environments, large amounts of dust will continuously fall and accumulate in the positioning slots. Over time, this dust accumulation not only changes the size and shape of the positioning slots but also creates significant resistance when inserting the positioning pins, causing them to jam during insertion. This can lead to locking failures and affect the normal operation of the system, necessitating urgent improvements. Summary of the Invention

At this time, the second air pump 19 is started, and the second air pump 19 extracts the air in the dust collection box 16 through the second conveying pipe 20, so that a negative pressure is formed in the dust collection box 16, and the air pressure at one end of the collection cover 17 is greater than the air pressure in the dust collection box 16, so that the dust at the collection cover 17 is sucked into the collection cover 17 through the first conveying pipe 18, realizing efficient dust collection, effectively preventing dust accumulation from causing deformation of the slot 6, reducing the insertion resistance of the positioning pin 10, and avoiding jamming; start the cylinder 9, and the cylinder 9 drives the positioning pin 10 to move downward, so that the positioning pin 10 is inserted into the slot 6 of the positioning plate 5, completing precise alignment and locking.
