Abstract
The utility model discloses a combined type air cylinder pad with a sealing ring. The combined type air cylinder pad with the sealing ring comprises a pad body, wherein the sealing ring is arranged on the pad body, air cylinder holes, threaded installation holes, positioning holes and water holes are distributed in the pad body inside the sealing ring, a sealing convex rib and a cylinder hole retainer are arranged at the edge of each air cylinder hole, tappet holes are formed in one side of the pad body at the outer side of the sealing ring, a silicon rubber sealing layer coats each tappet hole, air discharging holes and kidney-shaped limiting holes are distributed in the pad body outside the sealing ring, and arc positioning clamping grooves are distributed in one end of the pad body at intervals. The combined type air cylinder pad with the sealing ring is reasonable in design, convenient to machine and manufacture and low in manufacturing cost due to the structure of the single-layer pad body. Through the structure of the arc positioning clamping grooves and the positioning holes, the combined type air cylinder pad with the sealing ring is convenient to install and position. Due to the structure of the convex ribs and the cylinder hole retainers at the air cylinder holes and the structural design of the silicone rubber sealing layers on the tappet holes, the combined type air cylinder pad with the sealing ring improves the sealing performance and prolongs the service life.
