Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises an element.

The mounting device in the embodiment of the application can mount the sealing ring 5 on the shaft body 6, and can ensure that the sealing ring 5 cannot have adverse phenomena such as flanging or twisting in the mounting process of the sealing ring 5.

As shown in fig. 1, the seal ring in the embodiment of the present application is a special-shaped seal ring 5, where the special-shaped seal ring 5 includes an oval seal ring 5a or a square seal ring 5b, and the cross-sectional shape of the seal ring 5 may be circular. Here, (a) in fig. 1 illustrates an elliptical seal ring 5a, and (b) in fig. 1 illustrates a square seal ring 5b.

The mounting device of the sealing ring in the embodiment of the application comprises a support 1, a sliding rail mechanism 2 and a transferring mechanism 3, and the specific structure is introduced as follows, as shown in fig. 2 to 5:

as shown in fig. 2, the support 1 is arranged on the ground or a working surface, and the support 1 is used for carrying other structures.

As shown in fig. 3, the slide rail mechanism 2 is configured to drive the transfer mechanism 3 to adjust a working position, where the slide rail mechanism 2 includes a first slide rail 21, a first slide block 22, a second slide rail 23, and a second slide block 24; the first slide rail 21 is arranged on the support 1, the length direction of the first slide rail 21 is configured to be in a first horizontal direction, the first slide block 22 is arranged on the first slide rail 21, and the first slide block 22 can be driven to move in the first horizontal direction through the first slide rail 21; the second slide rail 23 is provided on the first slider 22, and a length direction of the second slide rail 23 is arranged in a height direction; the second slide block 24 is disposed on the second slide rail 23, and the second slide block 24 can be driven to move in the height direction by the second slide rail 23.

As shown in fig. 4, the transfer mechanism 3 is disposed on the second slider 24, where the transfer mechanism 3 includes a sleeve rod 31, a telescopic member 32, a push sleeve 33, and an outer sleeve 34, which is specifically described as follows:

As shown in fig. 5, the loop bar 31 is slidably disposed on the second slider 24 along the height direction, and the loop bar 31 can slide up and down relative to the second slider 24; the sleeve 31 is divided into two sections in the axial direction (i.e., the height direction) thereof, the upper section is a constant diameter section 312 (cylindrical shape), the lower section is a tapered section 311, the small end face (top face) of the tapered section 311 is downward, and the lower end face of the constant diameter section 312 is configured as the large end face (i.e., the bottom face of the tapered section 311) of the tapered section 311.

In the embodiment of the application, the tapered section 311 is arranged to enable the sleeve rod 31 to be accurately and quickly sleeved in the sealing ring 5, so that the alignment difficulty of the sealing ring 5 and the sleeve rod 31 is reduced, and the constant diameter section 312 of the sleeve rod 31 can circle the sealing ring 5, so that the sealing ring 5 is conveniently sleeved on the outer circumference of the shaft body 6 in the follow-up process. Wherein, the outer diameter of the equal diameter section 312 is larger than the inner diameter of the sealing ring 5 (for example, the outer diameter of the equal diameter section 312 is 1.1 to 1.5 times of the inner diameter of the sealing ring 5), so as to play the effect of rounding the sealing ring 5, in the embodiment of the application, if the sealing ring 5 is an elliptical sealing ring 5, the outer diameter of the equal diameter section 312 is larger than the long axis of the elliptical sealing ring 5, and if the sealing ring 5 is a square sealing ring 5b, the outer diameter of the equal diameter section 312 is larger than the long side of the square sealing ring 5 b. In the embodiment of the present application, the constant diameter section 312 of the rod 31 has an outer diameter equal to the outer diameter of the shaft body 6.

In some preferred embodiments, as shown in fig. 6, the sealing ring 5 to be installed is sleeved at one end of the constant diameter section 312 near the taper section 311, specifically, in the height direction, the lower end surface C ₁ of the constant diameter section 312 (i.e. the bottom surface of the taper section 311) is located between the upper surface C ₂ and the lower surface C ₃ of the sealing ring 5 to be installed, so that the sealing ring 5 to be installed can be sleeved at a transition position (i.e. the taper position 31 a) between the constant diameter section 312 and the taper section 311, and the sealing ring 5 to be installed is sleeved at the taper position 31a, so that the sealing ring 5 is in a supported round state, and meanwhile, the contact between the sealing ring 5 and the outer circumference of the constant diameter section 312 can be reduced as much as possible in the process of pushing the sealing ring 5 to be installed downwards, and thus, the defects such as twisting or flanging in the installation process of the sealing ring 5 can be avoided. The principle is as follows: because the roughness of each position of the outer circumference of the equal-diameter section 312 cannot be completely consistent, and the sealing ring 5 needs to be pushed downwards from the equal-diameter section 312 and transited to the shaft body 6 (namely, the inner circumference of the sealing ring 5 needs to perform relative motion with the outer circumference of the equal-diameter section 312), the sleeving position of the sealing ring 5 is selected at the taper position 31a between the equal-diameter section 312 and the taper section 311, so that the sealing ring 5 can be rounded, and the contact area and the contact time of the equal-diameter section 312 and the sealing ring 5 during relative motion can be reduced as much as possible, thereby reducing the probability of twisting or flanging of the sealing ring 5.

It should be noted that, because the position of the sealing ring 5 to be installed is known and fixed before the sealing ring 5 is sleeved by the sleeve rod 31, the sealing ring 5 to be installed can be easily sleeved at the taper position 31a between the constant diameter section 312 and the taper section 311 only by controlling the downward insertion depth of the sleeve rod 31, which is simple and fast.

The telescopic member 32 includes an actuator having telescopic capability, such as a servo cylinder, an electric push rod, or a telescopic cylinder. The telescopic piece 32 is arranged on the second sliding block 24, the telescopic direction of the telescopic piece 32 is configured to be the height direction, wherein the telescopic piece 32 and the sleeve rod 31 are coaxially arranged, and the telescopic end of the telescopic piece 32 is connected with the sleeve rod 31, so that the telescopic piece 32 can drive the sleeve rod 31 to move up and down.

As shown in fig. 7, the pushing sleeve 33 is coaxially sleeved on the outer circumference of the constant diameter section 312, and the inner circumference of the pushing sleeve 33 is in clearance fit with the constant diameter section 312, and the clearance is 0.1mm to 1mm, for example. The lower end surface of the push sleeve 33 is configured as a push surface 33a, the push surface 33a is a horizontal surface, and the push surface 33a can contact with the upper surface of the seal ring 5, so as to push the seal ring 5 to transition to the shaft body 6. The upper end of the push sleeve 33 is connected to the lower surface of the second slider 24 by a connecting member.

As shown in fig. 7 and 8, the outer sleeve 34 is coaxially provided on the outer circumference of the push sleeve 33, and an annular suction passage 3a is formed between the inner circumferential side of the outer sleeve 34 and the outer circumferential side of the push sleeve 33, the annular suction passage 3a being for sucking the seal ring 5 to be mounted so that the seal ring 5 maintains a circular posture. The reason why the annular suction passage 3a can generate suction is that the annular suction passage 3a communicates with an external negative pressure unit, and negative pressure is generated in the annular suction passage 3a by the negative pressure unit, thereby sucking the sealing ring 5 to be mounted. In the embodiment of the present application, the push sleeve 33 is provided with a plurality of holes 33b, one end of the holes 33b is connected to the annular suction channel 3a, and the other end of the holes 33b is connected to an external negative pressure unit.

In some preferred embodiments, referring to fig. 6 again, a limiting ring portion 341 extends downward from the lower end of the outer sleeve 34 opposite to the pushing surface 33a of the push sleeve 33, where a projection of the limiting ring portion 341 in a horizontal direction at least partially overlaps with the seal ring 5 to be mounted, and the limiting ring portion 341, the push sleeve 33 and the sleeve rod 31 are coaxial. Wherein the annular suction channel 3a is formed between the inner peripheral side of the limit ring portion 341 and the outer peripheral side of the push sleeve 33.

In some preferred embodiments, referring to fig. 6 again, the lower end surface of the limiting ring 341 is set to be a cambered surface 34a, and the radian of the cambered surface 34a is matched with the outer Zhou Hudu of the sealing ring 5 to be installed, so that the cambered surface 34a can be in contact with the outer periphery of the sealing ring 5.

In the embodiment of the application, the limiting ring part 341 can be used for limiting the diameter of the outer circle of the sealing ring 5, so that the sealing ring 5 is not turned over or twisted in the installation process, on the other hand, the pushing surface 33a and the cambered surface 34a of the limiting ring part 341 can be used for carrying out interference limitation on the sealing ring 5 from the height direction and the horizontal direction (namely the axial direction and the radial direction) so as to avoid the change of the posture of the sealing ring 5, and the annular suction channel 3a is used for adsorbing the sealing ring 5, so that the sealing ring 5 is kept in a circular posture before being installed in place, and further the adverse phenomena of turning over and the like of the sealing ring 5 are avoided.

In some preferred embodiments, the outer sleeve 34 is detachably connected to the push sleeve 33, and the detachable manner may be electromagnetic adsorption or threaded connection, etc., and the detachable manner may refer to the connection manner in the prior art. In the embodiment of the application, the outer sleeve 34 is detachably arranged, so that the outer sleeve can be conveniently replaced according to actual requirements, and then the outer sleeve is matched with sealing rings 5 with different specifications and shapes for installation, and meanwhile, the width of the annular suction channel 3a can be conveniently changed.

As shown in fig. 9 and 10, the mounting device according to the embodiment of the present application further includes a feeding mechanism 4, where the feeding mechanism 4 includes a vibration plate 41, a material conveying channel 42, and a material cutting unit 43, and the specific forms are as follows:

as shown in fig. 10, the vibration plate 41 is capable of generating vibration, and the structure of the vibration plate 41 can be referred to as an existing structure. The spiral channel 44 which spirals upwards is arranged in the vibration disc 41, the inlet end 44a of the spiral channel is correspondingly communicated with the inner bottom surface of the vibration disc 41, so that materials (namely the sealing ring 5) of the vibration disc 41 can be shaken into the spiral channel 44 under the vibration action of the vibration disc 41, and the sealing ring 5 moves upwards along the spiral channel 44 to the outlet end 44b of the spiral channel under the vibration of the vibration disc 41.

As shown in fig. 11, the outlet end 44b of the screw channel communicates with the inlet end 42a of the material conveying channel, and the seal ring 5 is shaken from the outlet end 44b of the screw channel into the material conveying channel 42 and is shake-transported forward along the length direction of the material conveying channel 42.

As shown in fig. 12, the cutting unit 43 includes a cutting block 431 and a cutting slide rail 432, the cutting block 431 is disposed at an outlet end 42b of the material conveying channel, the cutting block 431 is sequentially provided with a blocking edge 4311 and a receiving slot 4312 along the second horizontal direction, when the blocking edge 4311 corresponds to the outlet end 42b of the material conveying channel in the first horizontal direction, the blocking edge 4311 can block the outlet end 42b of the material conveying channel, so as to stop discharging; when the receiving groove 4312 corresponds to the outlet end 42b of the material conveying channel in the first horizontal direction, the receiving groove 4312 can play a role of receiving materials, namely, the receiving groove 4312 can receive the sealing ring 5 coming out of the outlet end 42b of the material conveying channel, wherein a matching hole 4313 (a round hole) is formed in the inner bottom surface of the receiving groove 4312, the inner diameter of the matching hole 4313 is larger than the outer diameter of the equal-diameter section 312, and the matching hole 4313 is used for providing a space for avoiding the sleeve rod 31 so that the sleeve rod 31 can sleeve the sealing ring 5 in the receiving groove 4312.

In the embodiment of the application, the cutting slide rail 432 drives the cutting block 431 to move in the second horizontal direction, so as to cut the corresponding relationship between the material edge 4311 and the material receiving groove 4312 and the outlet end 42b of the material conveying channel, thereby realizing intermittent discharging.

The cutting slide rail 432 is mounted below the material conveying channel 42 through the support 433, the sliding direction of the cutting slide rail 432 is configured to be the second horizontal direction, and the cutting slide rail 432 is connected with the cutting block 431, so that the cutting slide rail 432 can drive the cutting block 431 to move in the second horizontal direction. Wherein the first horizontal direction and the second horizontal direction vertically intersect in a horizontal plane.

In some preferred embodiments, the upper surface of the spiral channel 44 is provided with a sanding layer, through which the spiral channel 44 is in contact with the material (sealing ring 5). The purpose of the sanding layer is to increase the friction between the spiral channel 44 and the material (sealing ring 5), and when the sealing ring 5 is shaken and conveyed by the vibrating disc 41, the sealing ring 5 bonded together can be shaken and separated due to the large friction between the spiral channel 44 and the sealing ring 5. It should be noted that, because the sealing ring 5 is generally made of a flexible material and has a certain viscosity, the sealing ring 5 in the vibration disc 41 may be bonded together, but the frosted layer designed in the embodiment of the application has a certain roughness and the vibration disc 41 continuously vibrates, so that the sealing ring 5 is more easily vibrated and dispersed when the vibration disc 4 vibrates, and the sealing ring 5 bonded together can be separated.

In some preferred embodiments, as shown in fig. 12, the feeding mechanism 4 further includes a stopper 434, where the stopper 434 is disposed on the blanking block 431, and at least a portion of the stopper 434 extends to one side of the receiving slot 4312. The function of the design stop 434 can prevent the sealing ring 5 from falling out of the material receiving groove 4312, and plays a certain limiting role.

In some embodiments, since the sealing ring 5 may block the material conveying channel 42, in some preferred embodiments, the feeding mechanism 4 further includes an air blowing unit 45, referring again to fig. 10, the air outlet of the air blowing unit 45 is in communication with the material conveying channel 42, and the air blowing direction of the air blowing unit 45 is consistent with the length direction of the material conveying channel 42. The air blowing unit 45 in the embodiment of the application comprises a high-pressure air pump, the high-pressure air pump can generate a high-pressure air column, the ejection direction of the high-pressure air column is consistent with the length direction of the material conveying channel 42, and the sealing ring 5 blocked in the material conveying channel 42 can be blown forwards in a high-pressure air blowing mode, so that the stable feeding operation is ensured.

The embodiment of the application also discloses a method for installing the sealing ring, which adopts the device for installing the sealing ring to install, and comprises the following steps:

Step S1: the material in the vibration disc 41 is conveyed to the outlet end 42b of the material conveying channel along the spiral channel 44, the material receiving groove 4312 of the material cutting block 431 is driven by the material cutting slide rail 432 to move to correspond to the outlet end 42b of the material conveying channel, one sealing ring 5 falls into the material receiving groove 4312 from the outlet end 42b of the material conveying channel, and then the material blocking edge 4311 of the material cutting block 431 is driven by the material cutting slide rail 432 again to block the outlet end 42b of the material conveying channel;

Step S2: the first slide rail 21 drives the transfer mechanism 3 to move to the position right above the receiving groove 4312, the second slide rail 23 drives the transfer mechanism 3 to descend by a certain height, then the telescopic piece 32 of the transfer mechanism 3 stretches out and drives the sleeve rod 31 to move downwards, the cone section 311 of the sleeve rod 31 is inserted into the sealing ring 5 downwards, the sleeve rod 31 moves downwards by a certain distance, the sealing ring 5 is sleeved at the transition position of the cone section 311 and the equal-diameter section 312, and after the sealing ring 5 is rounded by the periphery of the equal-diameter section 312, the sleeve rod 31 drives the sealing ring 5 to lift upwards;

Step S3: when the sleeve rod 31 drives the sealing ring 5 to lift up until the sealing ring 5 contacts with the pushing surface 33a of the pushing sleeve 33, the external negative pressure unit starts to work, so that the annular suction channel 3a between the pushing sleeve 33 and the outer sleeve 34 has suction force, and the sealing ring 5 to be installed is adsorbed, as shown in (a) in fig. 13;

Step S4: the first slide rail 21 drives the transfer mechanism 3 and the sealing ring 5 to be installed to transversely move to the position right above the shaft body 6 along the first horizontal direction, and the sleeve rod 31 is coaxial with the shaft body 6;

Step S5: the second slide rail 23 drives the transfer mechanism 3 and the sealing ring 5 to be installed to move downwards, the lower end surface of the sleeve rod 31 firstly touches the upper end surface of the shaft body 6, and the sleeve rod 31 and the sealing ring 5 do relative dislocation movement due to the collision of the shaft body 6 to the sleeve rod 31, and meanwhile, the sleeve rod 31, the push sleeve 33 and the outer sleeve 34 do dislocation movement, as shown in (b) in fig. 13;
