[0022] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:

[0023] 1. The inner rubber ring installation device designed by the present invention utilizes the movement of the positioning push rod in the compression chamber to deform the inner rubber ring, and the overall volume is reduced in the clamping groove. The clamping groove ensures the accuracy of the position of the inner rubber ring until the inner rubber ring loses the constraint of the compression chamber after moving into the pipe fitting, and returns to its original shape, completing the installation of the inner rubber ring. This design has a simple overall structure and a small volume.

In this way, the inner rubber ring is not easily damaged, and the assembly effect after installation can be guaranteed, and the production efficiency of the product can be guaranteed.

[0024] 2. In the process of working, the space between the annular boss on the positioning push rod and the opening part of the compression chamber is relatively large. In the process of squeezing the inner rubber ring to deform, the inner rubber ring can easily slip out of the space, causing the inner rubber ring to fail to deform and shrink, or even cause damage to the inner rubber ring. The push sleeve can compensate for this space, ensuring that the inner rubber ring can deform and shrink smoothly and normally in the clamping groove, ensuring the normal installation of the inner rubber ring, and also protecting the inner rubber ring to prevent damage to the inner rubber ring.

[0025] 3. The design of the channel in the positioning push rod and the spray hole in the clamping groove of the present invention can spray lubricating liquid into the clamping groove to lubricate the inner rubber ring in the clamping groove, so that it can move and deform smoothly in the compression chamber, which is convenient for the installation of the inner rubber ring.

[0026] 4. The design of the rubber ring installation machine of the present invention has a simple overall structure, small size, light weight, convenient transportation, simple use and high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings.

[0040] Embodiment 1:

[0041] like Figure 1-Figure 5 As shown, a rubber ring installation machine includes a base 15, on which an inner rubber ring installation device is installed, and a loading device 16 is arranged next to the inner rubber ring installation device for conveying the inner rubber ring into the inner rubber ring installation device, and a first slide device 17 for fixing a push sleeve 2 9 is installed on the base 15, a second slide device 18 for fixing a push sleeve 7 is installed on the first slide device 17, and a third slide device 19 for fixing a positioning push rod 5 is installed on the second slide device 18, and the push sleeve 2 9, the push sleeve 7 and the positioning push rod 5 are located on the same axis.

[0042] The feeding device 16 mainly comprises a vibrating plate.

[0043] The push sleeve 2 9, the push sleeve 7 and the positioning push rod 5 transport the inner rubber ring 35 in the inner rubber ring installation device to the pipe fitting 33. The specific scheme is as follows.

[0044] like Figure 3 and Figure 4 As shown, the inner rubber ring installation device includes a mold jacket 1, a feed plate 4 and a positioning push rod 5. The mold jacket 1 is installed at the front end of the base 15 and protrudes from the upper end surface of the base 15. An inner rubber ring assembly channel 34 is formed in the mold jacket 1. One end of the inner rubber ring assembly channel 34 is a compression chamber 2, and the other end of the inner rubber ring assembly channel 34 is a release chamber 3. The compression chamber 2 is inclined along the inner wall so that the width of the compression chamber 2 is narrowed toward the release chamber 3; the feed plate 4 is tightly attached to the rear end surface of the mold jacket 1, and a feeding channel 32 is opened in the feed plate 4, and is connected to the loading device 16. The inner rubber ring 35 falls along the feeding channel 32 to the discharge port 8 at the lower end of the feed channel, and the discharge port 8 is arranged at the port of the compression chamber 2. A third slide device 19 is also provided on the base 15, and the rear end of the positioning push rod 5 is installed on the third slide seat 24, and the front end of the positioning push rod 5 is placed at the discharge port 8, so that the single inner rubber ring 35 at the discharge port 8 can be pushed into the compression chamber 2, and then the inner rubber ring 35 can be constrained and deformed in the positioning groove 6 at the front end of the positioning push rod 5 through the compression chamber 2. After the volume is reduced, the positioning push rod 5 sends the inner rubber ring 35 into the pipe fitting 33 in the release chamber 3 to complete the internal installation of the inner rubber ring 35.

[0045] The inner wall of the release chamber 3 is designed in a stepped shape so that pipes 33 of different specifications can be installed in the release chamber 3, thereby improving the applicability of the equipment.

[0046] The design of the rubber ring installation machine of the present invention has a simple overall structure, a small volume, a light weight, is convenient for transportation, is simple to use and has high efficiency.

[0047] At the same time, if Figure 5-Figure 7 As shown, more than one pushing sleeve 7 is sleeved on the positioning push rod 5, and the pushing sleeve 7 moves with the positioning push rod 5 and pushes the inner rubber ring 35. The pushing sleeve 7 is separated from the positioning push rod 5 after being pushed forward to the limit position; when the pushing sleeve 7 is in the limit position, its front end basically fits the inner wall of the compression chamber 2. This embodiment adopts two pushing sleeves, namely the pushing sleeve 7 and the pushing sleeve 2 9.

[0048] The inner rubber ring installation device designed by the present invention utilizes the movement of the positioning push rod 5 and the push sleeve in the compression chamber 2 to deform the inner rubber ring 35, and the overall volume is reduced in the positioning groove 6 until the inner rubber ring 35 loses the constraint of the compression chamber 2 after moving into the pipe 33, and returns to the original shape, completing the installation of the inner rubber ring 35. This design has a simple overall structure and a small volume. At the same time, the cooperation of the positioning push rod 5 and the compression chamber 2 acts on the inner rubber ring 35 as a whole, causing it to deform as a whole, rather than locally, so that the inner rubber ring 35 is not easily damaged, and the assembly effect after installation can be guaranteed, and the production efficiency of the product can be guaranteed.

[0049] like Figure 2 and Figure 3 As shown, the first slide device 17 is movably arranged on the base 15 through the guide rail 1 26 , and the push sleeve 2 9 moves along with it, and the front end of the positioning push rod 5 is movably placed in the push sleeve 2 9 .

[0050] The first slide device 17 includes a first driving member 27 and a first slide plate 28. The first driving member 27 is installed on the base 15. The first slide plate 28 is slidably set on the guide rail 1 26. The push sleeve 2 9 is set at the front end of the first slide plate 28. The first driving member 27 drives the push sleeve 2 9 to move horizontally on the base 15 through the first slide plate 28 to realize the separation of the inner rubber ring 35 in the feed channel.

[0051] The design of the push sleeve 2 9 of the present invention can place a single inner rubber ring 35 in the push sleeve 2 9, and then connect the compression chamber 2, so that the inner rubber ring 35 in the push sleeve 2 9 can accurately enter the compression chamber 2. At the same time, the push sleeve 2 9 can block the subsequent inner rubber rings 35, ensuring that a single inner rubber ring 35 is installed each time, ensuring the normal progress of the installation process, and ensuring installation efficiency.

[0052] The second slide device 18 is arranged on the first slide device 17 through the guide rail 29, the rear end of the push sleeve 7 is installed at the front end of the second slide device 18, and the front end of the push sleeve 7 is movably arranged in the push sleeve 2 9, and the movement of the push sleeve 7 is used to push the inner rubber ring 35 away from the push sleeve 2 9.

[0053] The second slide device 18 includes a second driving member 30 and a second slide plate 31. The second driving member 30 is installed on the first slide plate 28. The second slide plate 31 is slidably set on one of the guide rails 29 on the first slide plate 28. The second driving member 30 drives the second slide plate 31 to slide, thereby realizing the movement of the push sleeve 7 inside the push sleeve 7.

[0054] like Figure 6As shown, during the operation, there is a large space between the annular boss 13 on the positioning push rod 5 and the opening part of the compression chamber 2. During the process of squeezing the inner rubber ring 35 to deform, the inner rubber ring 35 can easily slip out of the space, causing the inner rubber ring 35 to fail to deform and shrink, or even cause damage to the inner rubber ring 35. The push sleeve 7 can compensate for this space, ensuring that the inner rubber ring 35 can deform and shrink smoothly and normally in the positioning groove 6, ensuring the normal installation of the inner rubber ring 35, and also protecting the inner rubber ring 35 to prevent damage to the inner rubber ring 35.

[0055] The third slide device 19 includes a third driving member 23 and a third slide plate 24. The rear end of the positioning push rod 5 is fixed on the third slide plate 24. The third slide plate 24 is slidably set on the second guide rail 29. The third driving member 23 is fixed on the second slide plate 31. The third driving member 23 pushes the third slide plate 24 to slide.

[0056] The output end of the third driving member 23 is provided with a slide bar 25 , and the fixing position of the third slide plate 24 and the slide bar 25 is adjusted, thereby adjusting the length of the guide portion 12 extending into the release chamber 3 .

[0057] The design of the slide bar 25 can ensure that the device can be installed with the inner rubber ring 35 of various types of pipe fittings 33, thereby improving the adaptability.

[0058] In order to ensure that the inner rubber ring 35 can be deformed smoothly in the compression chamber 2, a lubrication channel 10 is opened in the positioning push rod 5, and a spray hole 11 connected to the lubrication channel 10 is opened at the bottom of the positioning groove 6. The lubricating oil can pass through the lubrication channel 10 and the spray hole 11 to lubricate the inner rubber ring 35 in the positioning groove 6.

[0059] The design of the lubrication channel 10 provided in the positioning push rod 5 and the spray hole 11 in the positioning groove 6 of the present invention can spray the lubricating liquid into the positioning groove 6 to lubricate the inner rubber ring 35 in the positioning groove 6, so that it can move and deform smoothly in the compression chamber 2, and the installation of the inner rubber ring 35 is convenient.

[0060] A guide portion 12 is formed at the front end of the positioning push rod 5, and an annular boss 13 is formed on the outer wall of the positioning push rod 5 at the rear end of the guide portion 12. The diameter of the guide portion 12 is slightly smaller than the annular boss 13. The positioning groove 6 is located between the guide portion 12 and the annular boss 13. The annular boss 13 moves laterally in the active cavity 14 in the pushing sleeve 7.

[0061] The guide portion 12 can ensure that the positioning push rod 5 can accurately extend into the pipe fitting 33, thereby ensuring accurate installation of the inner rubber ring 35.

[0062] On the one hand, the annular boss 13 is used to push the inner rubber ring 35 to move; on the other hand, the annular boss 13 cooperates with the end surface of the movable cavity 14 to limit the moving distance of the positioning push rod 5 in the pushing sleeve 7, thereby preventing the positioning push rod 5 from detaching from the rear end of the pushing sleeve.

[0063] like Figure 8 As shown, in order to further improve the applicability, an arc-shaped petal body 20 is provided at the front end of the base 15, one end of the arc-shaped petal body 20 is connected to the base 15, and the other end is suspended to form a pressing end 21, and a gap 22 is formed between the pressing end 21 and the base 15, and a fixed position is formed between the arc-shaped petal body 20 and the base 15, and the mold jacket 1 is installed in the fixed position. By rotating the bolt on the base 15, the lower end of the bolt is pressed against the pressing end 21. As the bolt rotates, the gap 22 can be reduced, thereby achieving the effect of reducing the fixed position, thereby fixing the mold jacket 1 in the fixed position. When the mold jacket 1 needs to be smoother, the mold jacket 1 can be removed by simply loosening the bolt. It is simple, convenient and quick to use.

[0064] The driving members mentioned above can all be cylinders.

[0065] Working principle:

[0066] like Figure 5-Figure 7 As shown, the end of the pipe 33 is manually placed into the release chamber 3, and then the first slide device 17 slides forward and abuts against the opening of the compression chamber 2, separating an inner rubber ring 35 at the discharge port 8 from the other inner rubber rings 35, and the inner rubber ring 35 is placed in the push sleeve 2 9 and sleeved in the positioning groove 6 of the positioning push rod 5, and the inner rubber ring 35 is lubricated at the same time; then the second slide device 18 works, and the push sleeve 7 pushes the inner rubber ring 35 in the push sleeve 2 9 into the compression chamber 2, and then the third slide device 19 works, and the guide portion 12 of the positioning push rod 5 extends into When the inner rubber ring 35 is in the pipe fitting 33, the annular boss 13 of the positioning push rod 5 continues to push the inner rubber ring 35, causing it to continue to deform under the action of the compression chamber 2 until the inner rubber ring 35 moves to the connection between the release chamber 3 and the compression chamber 2. At this time, the inner rubber ring 35 reaches the minimum state, and then the positioning push rod 5 pushes the inner rubber ring 35 into the pipe fitting 33. Thereafter, the third slide device 19, the second slide device 18 and the first slide device 17 return to their initial positions in sequence, completing the installation of the entire inner rubber ring 35. The above actions can then be repeated to repeat the installation of the inner rubber ring 35.

[0067] The inner rubber ring is gradually pushed by the push sleeve 2, 9, push sleeve 7 and positioning push rod 5, and the compression chamber 2 is cooperated to realize the compression of the inner rubber ring. The overall compression effect is obvious, and the inner rubber ring is not damaged. It is simple and convenient to realize, and the installation efficiency is guaranteed.

[0068] Embodiment 2:

[0069] The structure of the second embodiment is basically the same as that of the first embodiment, and the difference lies in the related arrangement of the third slide device 19 , the second slide device 18 and the first slide device 17 .

[0070] The design of this embodiment is as follows:

[0071] like Figure 9-10 As shown, a third slide device 19 is slidably arranged on the base through a guide rail, and the first slide device 17 and the second slide device 18 are installed on the third slide device 19. The rear ends of the first slide device 17 and the first slide device 18 are connected to the rear end of the third slide device 19 through an elastic member 36. A limiting column 37 is arranged on the base 15, and the limiting column 37 limits the movement of the rear end of the first slide device 17 and the first slide device 18 respectively.

[0072] The third slide device 19 includes a driving member 3 23 and a third slide plate 24. The driving member 3 23 is installed on the base, and the output end is connected to the third slide plate 24. The end of the positioning push rod 5 is installed on the third slide plate 24. The driving member 3 23 drives it to slide on the base 15. The third slide plate 24 is provided with a slot 38 for avoiding the limit column 37. The slot 38 is mainly used to avoid the limit column 37, thereby realizing the limitation of the second slide plate 31.

[0073] The second slide device 18 includes a second slide plate 31, which is slidably mounted on the third slide plate 24 through a guide rail. The push sleeve 7 is mounted on the second slide plate 31, and an elastic member 36 is arranged on the side of the second slide plate 31, and the end of the elastic member 36 abuts against the third slide plate 24.

[0074] The second slide plate 31 is provided with a second slot 39 , which is located directly above the first slot 38 . The second slot 39 and the first slot 38 together avoid the limiting column 37 , thereby achieving the limiting of the first slide plate 28 by the limiting column 37 .

[0075] The first slide device 17 includes a first slide plate 28, which is slidably mounted on a second slide plate 31 through a guide rail. The push sleeve 29 is arranged on the first slide plate 28. An elastic member 36 is arranged on the side of the first slide plate 28. The end of the elastic member 36 abuts against the rear end of the third slide plate 24. The first slide plate 28 follows the second slide plate 31.

[0076] Specific movement mode: driving member 3 23 drives the third slide plate 24 to slide on the base 15, and the second slide device 18 and the first slide device 17 follow the third slide plate 24 to move. When the end of the push sleeve 29 abuts against the port of the compression chamber 2, the end of the first slide plate 28 abuts against the limit column 37, and the first slide plate 28 stops moving. At this time, the elastic member 36 is compressed, and the third slide plate 24 and the second slide plate 31 continue to slide. When the front end of the push sleeve 7 approaches the inner wall of the compression chamber 2, the front end of the second slide plate 31 abuts against the limit column 37 and stops moving. The third slide plate 24 continues to move forward until the positioning push rod 5 sends the inner rubber ring to the pipe fitting 33 in the release chamber to complete the installation of the inner rubber ring.

[0077] like Fig.10 As shown, the depths of the above-mentioned slot 1 38 and slot 2 39 are different, that is, the depth of slot 1 38 is greater than the depth of slot 2 39, thereby realizing the sequential limiting of the first slide plate 28 and the second slide plate 31 by the limiting column 37 to ensure the installation of the inner rubber ring.

[0078] The elastic member 36 may be a compression spring.

[0079] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
