Referring to fig. 1-7, the present invention relates to an installation tool 100. Only the structure and operation of the installation tool 100 according to the present invention will be described in detail.
Referring to fig. 1 to 3, the installation tool 100 of the present invention includes a housing 4 and a driving mechanism 5 disposed in the housing 4. The housing 4 includes a first case 41 and a second case 42 that are independent of each other, the first case 41 is provided with a first claw portion 410, and the second case 42 is provided with a second claw portion 420. At least one of the first housing 41 and the second housing 42 is movable away from the other to increase the distance between the first claw 410 and the second claw 420 by the driving force of the driving mechanism 5. The mounting tool provided by the invention utilizes the driving mechanism 5 to drive the first claw part 410 and the second claw part 420 to perform flaring action on the stainless steel ring, so that the convenience of mounting is improved.
Referring to fig. 1 to 3, the driving mechanism 5 includes a first cylinder 51, a first piston rod 510, a second cylinder 52, and a second piston rod 520. The first cylinder 51 and the second cylinder 52 are disposed at a distance from each other and opposite to each other, the first piston rod 510 has a first free end 5101 exposed from the first cylinder 51 and protruding toward the second cylinder 52, the second piston rod 520 has a second free end 5201 exposed from the second cylinder 52 and protruding toward the first cylinder 51, and the first free end 5101 is in contact with the second free end 5201. Since the first free end portion 5101 is kept in contact with the second free end portion 5201 for a long time, when oil/gas is pumped into the first cavity 5100 and the second cavity 5200 by the pumping tool, the oil pressure/gas pressure increases the volume of the first cavity 5100 and the second cavity 5200, and when the first piston rod 510 and the second piston rod 520 are fixed, the oil pressure/gas pressure on both sides is respectively applied by the combined force of the first piston rod 510 and the second piston rod 520, so that the first cylinder 51 moves to the left side as shown in fig. 1 to 7 and the second cylinder 52 moves to the right side as shown in fig. 1 to 7, the first cylinder 51 moves while the first housing 41 is driven, and the second cylinder 52 moves while the second housing 42 is driven. Thus, in use of the present invention, the first cylinder 51 and the second cylinder 52 move, and the first piston rod 510 and the second piston rod 520 are stationary.
Referring to fig. 1 to 3, at least one guide plate 6 is disposed on the housing 4, and the guide plate 6 connects the first housing 41 and the second housing 42 to perform a guiding function during a relative moving away of the first housing 41 and the second housing 42. Specifically, the guide plate 6 includes a first guide plate 61 and a second guide plate 62, and the first guide plate 61 and the second guide plate 62 are distributed on opposite sides of the first cylinder 51 and the second cylinder 52. Therefore, the first guide plate 61 and the second guide plate 62 provide a moving track of the first cylinder 51 and the second cylinder 52, and the first cylinder 51 and the second cylinder 52 do linear reverse movement along the track, thereby ensuring the smoothness of movement.
Referring to fig. 3, the first cylinder 51 and the first housing 41, and the second cylinder 52 and the second housing 42 are respectively positioned by means of a shoulder 7, so that the cylinders 51, 52 are stably and reliably positioned with the housing 4.
Referring to fig. 3, the first piston rod 510 has a first tail end 5102 opposite to the first free end 5101 and embedded in the first cylinder 51, and a first cavity 5100 is provided between the first cylinder 51 and the first tail end 5102. The second piston rod 520 has a second tail end 5202 disposed opposite to the second free end 5201 and embedded in the second cylinder 52, and a second cavity 5200 is provided between the second cylinder 52 and the second tail end 5202. It is apparent that the first cavity 5100 and the second cavity 5200 are used for pumping oil/gas to be able to power the first cylinder 51 and the second cylinder 52.
Referring to fig. 4 and 5, the initial state between the first jaw 410 and the second jaw 420 may be a closed state of zero distance (d0=0), in which case the moving away can change the closed state between the first jaw 410 and the second jaw 420 from the closed state of zero distance d0=0 to an open state separated by a distance Dn > d0=0.
Referring to fig. 6 and 7, the initial state between the first jaw 410 and the second jaw 420 may be a first open state spaced apart by a first distance (D1 > 0), in which case the moving away can change the first open state between the first jaw 410 and the second jaw 420 from a first open state spaced apart by a first distance D1>0 to a second open state spaced apart by a second distance D2> D1> 0.
The difference between the above two cases is only that the initial state is different between the first claw 410 and the second claw 420 (d0=0 in embodiment 1 or D1>0 in embodiment 2), and the final effect is the same, or that the stainless steel ring is flared by the increase of the distance between the first claw 410 and the second claw 420 (Dn > D0 in embodiment 1 or D2> D1 in embodiment 2).
