Technical Field

The present application relates to the field of sealing ring installation, and in particular to a sealing ring installation device and installation method.

Background technique

In the prior art, a sealing ring needs to be installed on the outer periphery of the shaft to achieve a sealing effect.

In a second aspect, an embodiment of the present application discloses a method for installing a sealing ring, using a sealing ring installation device, and the installation method includes:

The first slide rail drives the transfer mechanism to move to the top of the sealing ring, and the second slide rail drives the transfer mechanism to move downward a certain distance;

The telescopic member drives the sleeve rod downward to be inserted into the sealing ring. When the outer circumference of the equal diameter section contacts the inner circumference of the sealing ring, the telescopic member drives the sleeve rod upward. After the push surface of the push sleeve contacts the sealing ring, negative pressure is created in the annular suction channel, and the annular suction channel adsorbs the sealing ring.

The second slide rail drives the transfer mechanism to move downward. After the lower end face of the sleeve rod hits the upper end face of the shaft body, the second slide rail drives the transfer mechanism to continue to move downward. The sleeve rod, the push sleeve and the outer sleeve perform relative dislocation movement. The lower end face of the push sleeve pushes the sealing ring to move downward until the sealing ring is sleeved on the outer periphery of the shaft body. Then the annular suction channel releases the adsorption of the sealing ring, thereby completing the installation of the sealing ring, and the push sleeve and the outer sleeve are lifted up.

The installation device of the embodiment of the present application includes a support, a slide rail mechanism and a transfer mechanism. The slide rail mechanism includes a first slide rail, a first slider, a second slide rail and a second slider; the transfer mechanism includes a sleeve rod, a telescopic member, a push sleeve and an outer sleeve; the sleeve rod includes a tapered section and an equal-diameter section. When the sealing ring needs to be installed, the first slide rail drives the transfer mechanism to move horizontally to the top of the sealing ring to pick up the material, and then the second slide rail drives the transfer mechanism to drop to a certain height, and then the telescopic member drives the sleeve rod to move downward, and the tapered section of the sleeve rod is inserted downward onto the sealing ring. The sealing ring is finally sleeved on one end of the equal-diameter section close to the tapered section. There are two advantages to sleeve the sealing ring to be installed in this position. First, the outer circumference of the equal-diameter section can be used to support the sealing ring to be installed, so that it can be smoothly sleeved onto the external shaft body. Second, the sealing ring only needs to be slightly pushed downward, and the sealing ring will enter the sleeve. The tapered range of the rod can make the inner periphery of the sealing ring break away from the contact with the outer periphery of the sleeve rod, thereby reducing the possibility of the sealing ring flanging and twisting during the installation process. On the other hand, an annular suction channel is formed between the push sleeve and the outer sleeve in the embodiment of the present application, and the annular suction channel can absorb the sealing ring to be installed to ensure the stability of the sealing ring and avoid its twisting or flanging. When installing the sealing ring, the lower end surface of the push sleeve can act as a pushing surface. Driven by the second slide rail, the pushing surface pushes the sealing ring and the sleeve rod to move in an offset manner, and pushes the sealing ring to the outer periphery of the shaft body, thereby completing the installation of the sealing ring.

The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

The installation device in the application embodiment can install the sealing ring 5 on the shaft body 6, and can ensure that the sealing ring 5 will not have undesirable phenomena such as flanging or twisting during the installation process.

As shown in FIG1 , the sealing ring in the embodiment of the present application is a special-shaped sealing ring 5, which includes an elliptical sealing ring 5a or a square sealing ring 5b, and the cross-sectional shape of the sealing ring 5 can be circular. Among them, FIG1 (a) shows an elliptical sealing ring 5a, and FIG1 (b) shows a square sealing ring 5b.

The sealing ring installation device in the embodiment of the present application includes a support 1, a slide rail mechanism 2 and a transfer mechanism 3, and the specific structure is described as follows, as shown in Figures 2 to 5:

As shown in FIG. 2 , the support 1 is arranged on the ground or a work surface, and the support 1 is used to support other structures.

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

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

As shown in FIG5 , the sleeve rod 31 is slidably inserted into the second slider 24 along the height direction, and the sleeve rod 31 can slide up and down relative to the second slider 24; the sleeve rod 31 is divided into two sections along its axial direction (i.e., the height direction), the upper section is an equal-diameter section 312 (cylindrical), and the lower section is a conical section 311, the small end face (top face) of the conical section 311 faces downward, and the lower end face of the equal-diameter section 312 is configured as the large end face of the conical section 311 (i.e., the bottom face of the conical section 311).

In the embodiment of the present application, the conical section 311 is provided so that the sleeve rod 31 can be accurately and quickly sleeved in the sealing ring 5, reducing the difficulty of aligning the sealing ring 5 and the sleeve rod 31, and the equal diameter section 312 of the sleeve rod 31 can round the sealing ring 5, so as to facilitate the subsequent sleeve of the sealing ring 5 on the outer circumference of the shaft body 6. Among them, the outer diameter of the equal diameter section 312 is greater 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 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 present application, if the sealing ring 5 is an elliptical sealing ring 5, the outer diameter of the equal diameter section 312 is greater 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 greater than the long side of the square sealing ring 5b. In the embodiment of the present application, the outer diameter of the equal diameter section 312 of the sleeve rod 31 is equal to the outer diameter of the shaft body 6.

In some preferred schemes, as shown in FIG. 6 , the sealing ring 5 to be installed is sleeved on one end of the equal diameter section 312 close to the cone section 311. Specifically, in the height direction, the lower end surface C ₁ of the equal diameter section 312 (i.e., the bottom surface of the cone section 311) is located between the upper surface C ₂ and the lower surface C ₃ of the sealing ring 5 to be installed. In this way, the sealing ring 5 to be installed can be sleeved at the transition position (i.e., the tapered position 31a) between the equal diameter section 312 and the cone section 311. The sealing ring 5 to be installed is sleeved at the tapered position 31a, which can ensure that the sealing ring 5 is in a rounded state and minimize the contact between the sealing ring 5 and the outer circumference of the equal diameter section 312 in the process of pushing the sealing ring 5 downward for installation, thereby avoiding distortion or flanging during the installation of the sealing ring 5. The principle is as follows: since the roughness of each position on the outer circumference of the equal-diameter section 312 cannot be completely consistent, and the sealing ring 5 needs to be pushed downward from the equal-diameter section 312 and transition to the shaft body 6 (that is, the inner circumference of the sealing ring 5 needs to move relative to the outer circumference of the equal-diameter section 312), therefore, selecting the sleeve position of the sealing ring 5 at the tapered position 31a between the equal-diameter section 312 and the tapered section 311 can not only ensure that the sealing ring 5 is rounded, but also minimize the contact area and contact time between the equal-diameter section 312 and the sealing ring 5 during relative movement, thereby reducing the probability of distortion or flanging of the sealing ring 5.

It should be noted that, since the position of the sealing ring 5 to be installed is known and fixed before it is put on by the sleeve rod 31, it is only necessary to control the downward insertion depth of the sleeve rod 31 to easily put the sealing ring 5 to be installed on the tapered position 31a between the equal diameter section 312 and the tapered section 311, which is simple and quick.

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

As shown in Fig. 7, the push sleeve 33 is coaxially sleeved on the outer circumference of the equal diameter section 312, and the inner circumference of the push sleeve 33 is gap-matched with the equal diameter section 312, and the size of the gap is, for example, 0.1mm to 1mm. The lower end surface of the push sleeve 33 is configured as a push surface 33a, which is a horizontal surface. The push surface 33a can contact the upper surface of the sealing ring 5, thereby pushing the sealing 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 through a connecting component.

As shown in Figures 7 and 8, the outer sleeve 34 is coaxially sleeved on the outer circumference of the push sleeve 33, and an annular suction channel 3a is formed between the inner circumference of the outer sleeve 34 and the outer circumference of the push sleeve 33, and the annular suction channel 3a is used to absorb the sealing ring 5 to be installed, so that the sealing ring 5 maintains a circular posture. Among them, the reason why the annular suction channel 3a can generate suction is that the annular suction channel 3a is connected to the external negative pressure unit, and the negative pressure unit is used to create a negative pressure in the annular suction channel 3a, thereby sucking the sealing ring 5 to be installed. In the embodiment of the present application, a plurality of channels 33b are provided on the push sleeve 33, one end of the channel 33b is connected to the annular suction channel 3a, and the other end of the channel 33b is connected to the external negative pressure unit.

In some preferred solutions, please refer to FIG. 6 again, the lower end of the outer sleeve 34 extends downward relative to the push surface 33a of the push sleeve 33 to be provided with a limit ring portion 341, the projection of the limit ring portion 341 in the horizontal direction at least partially overlaps with the sealing ring 5 to be installed, and the limit ring portion 341, the push sleeve 33 and the sleeve rod 31 are coaxial. The inner circumference of the limit ring portion 341 and the outer circumference of the push sleeve 33 form the annular suction channel 3a.

In some preferred schemes, please refer to Figure 6 again, the lower end surface of the limiting ring portion 341 is set to an arc surface 34a, the curvature of the arc surface 34a matches the curvature of the outer periphery of the sealing ring 5 to be installed, and the arc surface 34a can be in close contact with the outer periphery of the sealing ring 5.

In the embodiment of the present application, the limiting ring portion 341 can be used to limit the outer diameter of the sealing ring 5 to ensure that the sealing ring 5 will not be flanging or twisting during the installation process. On the other hand, the pushing surface 33a and the arc surface 34a of the limiting ring portion 341 of the embodiment of the present application can restrict the sealing ring 5 from the height direction and the horizontal direction (i.e., the axial and radial directions) to avoid the posture of the sealing ring 5 from changing. At the same time, the annular suction channel 3a is used to absorb the sealing ring 5 so that the sealing ring 5 remains in a circular posture before it is installed in place, thereby avoiding the occurrence of undesirable phenomena such as flanging of the sealing ring 5.

In some preferred solutions, the outer sleeve 34 is detachably connected to the push sleeve 33, and the detachable method can be electromagnetic adsorption or threaded connection, etc. The specific detachable method can also refer to the connection method in the prior art. In the embodiment of the present application, the outer sleeve 34 is detachable so that it can be easily replaced according to actual needs, and then matched with the installation of sealing rings 5 of different specifications and shapes, and at the same time, it can be easy to change the width of the annular suction channel 3a.

As shown in FIG. 9 and FIG. 10 , the installation device of the embodiment of the present application further includes a feeding mechanism 4, which includes a vibration plate 41, a material conveying channel 42 and a cutting unit 43, and the specific form is as follows:

As shown in FIG10 , the vibration disk 41 can generate vibration, and the structure of the vibration disk 41 can refer to the existing structure. A spiral channel 44 spiraling upward is provided in the vibration disk 41, and the inlet end 44a of the spiral channel is correspondingly connected to the inner bottom surface of the vibration disk 41, so that the material (i.e., the sealing ring 5) of the vibration disk 41 can be shaken into the spiral channel 44 under the vibration of the vibration disk 41, and the sealing ring 5 moves upward along the spiral channel 44 to the outlet end 44b of the spiral channel under the vibration of the vibration disk 41.

As shown in FIG. 11 , the outlet end 44b of the spiral channel is connected to the inlet end 42a of the material conveying channel. The sealing ring 5 is shaken into the material conveying channel 42 from the outlet end 44b of the spiral channel and is shaken forward along the length direction of the material conveying channel 42 for transportation.

As shown in FIG12 , the cutting unit 43 includes a cutting block 431 and a cutting slide rail 432. The cutting block 431 is arranged at the outlet end 42b of the material conveying channel. The cutting block 431 is sequentially provided with a blocking edge 4311 and a receiving groove 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, thereby stopping the discharge of the material; when the receiving groove 4312 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, thereby stopping the discharge of the material; When the outlet end 42b of the material delivery channel corresponds in the first horizontal direction, the material receiving groove 4312 can play the role of connecting the material, that is, the material receiving groove 4312 can receive the sealing ring 5 coming out from the outlet end 42b of the material delivery channel, wherein a matching hole 4313 (circular hole) is provided on the inner bottom surface of the material receiving groove 4312, and the inner diameter of the matching hole 4313 is larger than the outer diameter of the equal diameter section 312, and the function of the matching hole 4313 is to provide a space for avoiding the sleeve rod 31, so as to facilitate the sleeve rod 31 to take the sealing ring 5 in the material receiving groove 4312.

In the embodiment of the present application, the cutting block 431 is driven to move in the second horizontal direction by the cutting slide rail 432, thereby switching the corresponding relationship between the blocking edge 4311 and the receiving groove 4312 and the outlet end 42b of the material conveying channel to achieve intermittent discharging.

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

In some preferred schemes, a frosted layer is provided on the upper surface of the spiral channel 44, and the spiral channel 44 contacts the material (sealing ring 5) through the frosted layer. The purpose of designing the frosted layer is to increase the friction between the spiral channel 44 and the material (sealing ring 5). When the sealing ring 5 is shaken and transported by the vibration disk 41, the friction between the spiral channel 44 and the sealing ring 5 is large, and the sealing ring 5 that is bonded together can be shaken apart. It should be noted that since the sealing ring 5 is generally made of a flexible material with a certain degree of viscosity, the sealing ring 5 in the vibration disk 41 may be bonded together, and the frosted layer designed in the embodiment of the present application has a certain degree of roughness and the vibration disk 41 vibrates continuously, so it is easier to shake the sealing ring 5 apart when the vibration disk 4 vibrates, and then the sealing ring 5 that is bonded together can be separated.

In some preferred solutions, as shown in FIG12 , the feeding mechanism 4 further includes a stopper 434, which is disposed on the cutting block 431, and at least a portion of the stopper 434 extends to one side of the receiving groove 4312. The stopper 434 is designed to prevent the sealing ring 5 from falling out of the receiving groove 4312, and plays a certain limiting role.

In some embodiments, since the sealing ring 5 may be blocked in the material conveying channel 42, in some preferred solutions, the feeding mechanism 4 also includes a blowing unit 45, please refer to Figure 10 again, the air outlet of the blowing unit 45 is connected to the material conveying channel 42, and the blowing direction of the blowing unit 45 is consistent with the length direction of the material conveying channel 42. The blowing unit 45 in the embodiment of the present application includes a high-pressure air pump, which can generate a high-pressure air column, and the ejection direction of the high-pressure air column is consistent with the length direction of the material conveying channel 42. The sealing ring 5 blocked in the material conveying channel 42 can be blown forward by high-pressure blowing to ensure the stable feeding work.

The embodiment of the present application further discloses a method for installing a sealing ring, which is installed by using the sealing ring installation device. The installation method includes:

Step S1: the material in the vibrating plate 41 is transported to the outlet end 42b of the material conveying channel along the spiral channel 44, the cutting slide rail 432 drives the receiving groove 4312 of the cutting block 431 to move to correspond to the outlet end 42b of the material conveying channel, a sealing ring 5 falls into the receiving groove 4312 from the outlet end 42b of the material conveying channel, and then the cutting slide rail 432 drives the retaining edge 4311 of the cutting block 431 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 top of the receiving trough 4312, and the second slide rail 23 drives the transfer mechanism 3 to descend to a certain height, and then the telescopic member 32 of the transfer mechanism 3 extends and drives the sleeve rod 31 to move downward, and the cone section 311 of the sleeve rod 31 is inserted downward into the sealing ring 5, and the sleeve rod 31 moves downward for a certain distance, so that the sealing ring 5 is sleeved at the transition position between the cone section 311 and the equal diameter section 312, and after the sealing ring 5 is rounded by the outer periphery of the equal diameter section 312, the sleeve rod 31 drives the sealing ring 5 to be lifted up;

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

Step S4: the first slide rail 21 drives the transfer mechanism 3 and the sealing ring 5 to be installed to move horizontally along the first horizontal direction to just above the shaft body 6, 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 downward, and the lower end surface of the sleeve rod 31 first hits the upper end surface of the shaft body 6. Due to the resistance of the shaft body 6 to the sleeve rod 31, the sleeve rod 31 and the sealing ring 5 move relative to each other, and the sleeve rod 31 also moves relative to each other with the push sleeve 33 and the outer sleeve 34, as shown in (b) of Figure 13;

The second slide rail 23 continuously drives the transfer mechanism 3 to move downward, so that the push surface 33a of the push sleeve 33 pushes the sealing ring 5 downward, and the annular suction channel 3a maintains the adsorption of the sealing ring 5. When the sealing ring 5 is downwardly sleeved on the predetermined position of the shaft body 6, the external negative pressure unit stops working, and the annular suction channel 3a releases the adsorption force on the sealing ring 5, so that the sealing ring 5 is sleeved on the outer periphery of the shaft body 6. At this time, the installation of the sealing ring 5 is completed, as shown in (c) of Figure 13;

Finally, the second slide rail 23 drives the transfer mechanism 3 to move upward.

The above is only a specific implementation of the present application. Those skilled in the art can clearly understand that for the convenience and simplicity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here. It should be understood that the protection scope of the present application is not limited to this. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in this application, and these modifications or replacements should be included in the protection scope of this application.
