Detailed Description
The technical scheme of the utility model is further described below with reference to the accompanying drawings.
Referring to fig. 1-3, the sealing ring mounting device comprises a center support arm 1, two compression support arms 2 and a transmission device for controlling the two compression support arms to open and close and rotate, wherein the transmission device comprises a ratchet device 3, a rotary stretching head 9 positioned below the ratchet device and an adjusting screw rod 10. The ratchet device 3 controls the two compaction support arms 2 to rotate, and the rotary stretching head 9 and the adjusting screw rod 10 are matched to drive the two compaction support arms 2 to open and close. The center support arm 1 is fixed below the ratchet device 3 through an adjusting screw rod 10, namely the adjusting screw rod 10 is arranged between the ratchet device and the center support arm 1. Two hold-down arms 2 are distributed on both sides of the adjusting screw 10. The ratchet 3 upper end is equipped with ratchet shaft 5, inside be equipped with ratchet shaft rotate two output shafts 5 of being connected, ratchet shaft 5 and two output shafts 6 pass through the gear box cooperation and connect, and the rotation direction of two output shafts is opposite, is equipped with handle 4 on the ratchet shaft, rotates handle 4 and drives ratchet shaft 5 rotation, and then drives two output shafts 6 reverse rotation, and two output shafts 6 link to each other with two compaction support arms 2 through ball joint formula universal joint 7 respectively to make two compaction support arms reverse rotation simultaneously. The lower end of the compaction support arm 2 is provided with a compaction end 11 in an outward protruding mode, and the compaction end 11 rotates around the central axis of the compaction support arm under the condition that the compaction support arm rotates. The ratchet device 3 further comprises a direction adjusting knob 8 for adjusting the ratchet rotation direction of the ratchet shaft, and when the rotation direction of the pressing support arm needs to be adjusted, the direction adjusting knob 8 is adjusted, so that the ratchet shaft can reversely rotate under the rotation of the handle. The periphery of the adjusting screw rod 10 is provided with threads, and the rotary stretching head 9 is sleeved on the outer side of the adjusting screw rod 10 and is in threaded connection with the adjusting screw rod.
As shown in fig. 5, the rotary stretching head 9 is provided with spiral slideways 12 at two sides of the adjusting screw rod respectively, and the two spiral slideways are opposite in rotation direction, and the two compaction support arms are respectively positioned in the two spiral slideways. When the pressing support arms need to be rotated, the rotation Zhong Zhangtou is kept not to rotate, and the two pressing support arms rotate in the spiral channel under the rotation of the ratchet shaft 5, the gear box and the output shaft, so that the pressing ends are driven to rotate. When the compression support arm needs to be opened, the rotary stretching head 9 is rotated, two spiral channels in the rotary stretching head rotate, the compression support arm is extruded, and the two compression support arms are opened back and forth to form a certain angle under the action of the spherical hinge type universal coupling.
The working principle of the utility model is as follows: the center support arm 1 is propped against the outer wall of the sealing ring, the two pressing support arms are inserted into the sealing ring, the handle 4 is rotated, the handle 4 drives the ratchet shaft 5 to rotate, and then drives the gear box meshed with the ratchet shaft 5 inside the ratchet 3 to rotate, and further drives the two pressing support arms to reversely rotate simultaneously, and the two pressing ends rotate around the central axis of the pressing support arms, so that the sealing ring is extruded and deformed, as shown in fig. 4. And after the sealing ring is extruded to a proper size, placing the extruded sealing ring in the cylinder barrel arm, and aligning the groove to be installed. At this time, the direction adjusting knob 8 of the ratchet 3 is adjusted, and the handle 4 is rotated to reversely loosen the sealing ring by the two pressing arms, so that the sealing ring is rebounded into a ring shape and enters the required installation groove.
