Description

Technical Field

[0001] This invention relates to the field of assembly technology for shaft-mounted Glyd rings, and in particular to an assembly process for shaft-mounted Glyd rings. Background Technology

[0002] A shaft Glyd ring is generally composed of an O-ring and a PTFE ring (outer ring). During operation, the O-ring applies force, and the Glyd ring is a double-acting piston seal. It has the characteristics of low friction, no creep, low starting force, high pressure resistance, and good wear resistance, and is widely used in hydraulic or similar hydraulic piston motion devices.

[0003] The installation of a Glyd ring on a shaft involves installing the Glyd ring into the corresponding mounting slot on the shaft. Since the inner diameter of the Glyd ring is smaller than the diameter of the shaft, the outer ring of the Glyd ring needs to be expanded to a size slightly larger than the shaft diameter before it can be installed into the mounting slot.

[0004] Currently, when assembling Glyd rings for shafts, the outer ring is immersed in a heated liquid (water or oil) (approximately 80℃-120℃) for a certain period of time before the inner ring is enlarged and inserted into the mounting groove. This method has the following main disadvantages:

[0005] 1. The installation of the outer ring of the shaft-mounted Glyd ring must be quick, generally within 10-15 seconds. If it takes more than 15 seconds, the outer ring hardens due to temperature drop, reducing its elasticity and making it difficult to install or causing it to break. When heating the outer ring with liquid (water or oil), after heating to the predetermined temperature and removing it, the liquid adhering to the outer ring must be thoroughly cleaned. This process typically takes 2-5 seconds, further shortening the installation time. This is the main reason why using liquid heating can cause the outer ring to break or fail to return to the required dimensions after assembly.

[0006] 2. The installation of the outer ring of the shaft-mounted Glyd ring requires speed, so the heating fluid should be placed near the installation area. Since pistons and cylinders are precision parts, the assembly area must be a dust-free, dry, and isolated zone. Water heating generates steam, significantly increasing humidity in the assembly area, making parts, equipment, and instruments prone to rust. Oil heating produces fumes, and prolonged work in an isolated, fume-filled area poses a significant health risk to personnel.

[0007] 3. The liquid is heated to 80℃-120℃, and the heating source is close to the installation area, which poses a safety risk of liquid spillage and burns to personnel. Summary of the Invention

[0008] In view of the above, the present invention provides a process for assembling a shaft-mounted Glyd ring, which aims to overcome the shortcomings pointed out in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0018] in:

[0019] The parts to be installed include a piston and a piston rod that are connected to each other. The piston has a first mounting groove and a second mounting groove on its circumferential side for mounting a shaft Glyd ring.

[0020] The assembly fixture includes a guide sleeve and a push ring sleeve. The guide sleeve includes a tapered portion and a straight portion connected to each other. The tapered portion has a first hole, and the straight portion has a second hole communicating with the first hole. The diameter of the second hole is larger than the diameter of the first hole. The inner wall of the second hole can slide in contact with the circumferential side of the piston. One end face of the push ring sleeve has a central hole, and the inner diameter of the other end can be varied.

[0021] The calibration fixture includes a calibration section and a diameter reduction section that are connected to each other; the inner diameter of each part of the calibration section is the same, and the inner wall of the calibration section can slide in contact with the circumferential side of the piston; the diameter reduction section is flared, and the minimum inner diameter of the diameter reduction section is the same as the inner diameter of the calibration section.

[0022] In some embodiments of the present invention, step S4 includes:

[0023] The outer ring of the Gladius ring is suspended and placed in an electric heating drying oven for constant temperature heating.

[0024] In some embodiments of the present invention, installing the outer ring of the Glydette in the second mounting groove includes:

[0025] Quickly place the heated outer ring of the Glyd ring onto the conical part, and immediately use the push ring sleeve to push the outer ring of the Glyd ring quickly to assemble the outer ring of the Glyd ring into the second mounting groove. Quickly remove the push ring sleeve and guide sleeve, and rotate the outer ring of the Glyd ring so that the O-ring accurately contacts the corresponding groove of the outer ring of the Glyd ring.

[0026] In some embodiments of the present invention, step S3, when fitting the straight portion of the guide sleeve onto the piston, includes:

[0027] First, place the adjusting fixture at the bottom of the second hole, then fit the straight part onto the piston:

[0028] The adjusting fixture includes a first pad, a second pad, and an adjusting rod; the diameters of the first pad and the second pad are both larger than the diameter of the first hole, the first pad and the second pad are arranged in parallel, and the adjusting rod is used to adjust the distance between the first pad and the second pad.

[0029] In some embodiments of the present invention, the adjusting rod is threadedly connected to the first pad, and one end of the adjusting rod is rotatably connected to the second pad.

[0030] In some embodiments of the present invention, installing the outer ring of the Glydette in the first mounting groove includes:

[0031] Adjust the distance between the first and second pads to expose the first mounting groove. Quickly place the heated outer ring of the Glyd ring on the conical part. Immediately use the push ring sleeve to quickly push the outer ring of the Glyd ring to assemble it into the first mounting groove. Rotate the outer ring of the Glyd ring so that the O-ring accurately contacts the corresponding groove of the outer ring of the Glyd ring.

[0032] In some embodiments of the present invention, the adjusting fixture further includes:

[0033] An extension rod, fixedly connected to the adjusting rod, can pass through the central hole;

[0034] The sliding sleeve is slidably connected to the extension rod.

[0035] The connecting rod is hinged at one end to the sliding sleeve and at the other end to the slider;

[0036] The slider is slidably connected to the second pad.

[0037] The clamping plate is fixed to the slider at one end, and the other end extends into the piston after passing through the second pad.

[0038] The limiting sleeve is threaded to one end of the extension rod. The limiting sleeve contacts one end of the sliding sleeve. The limiting sleeve has an extension portion, the diameter of which is larger than the diameter of the central hole.

[0039] In some embodiments of the present invention, the diameter of the end of the piston rod furthest from the piston is smaller than the diameter of the piston; in step S6, when calibrating the outer ring of the Glyd ring using a calibration fixture, the following is included:

[0040] Step S61: After installing the outer ring of the Glyd ring in the second mounting groove and the first mounting groove, keep the push ring sleeve, guide sleeve and piston connected, so that the reduced diameter part faces the piston, and put the correction fixture on the piston from the piston rod end;

[0041] Step S62: Thread the limiting sleeve onto the extension rod, turn the limiting sleeve, push the sliding sleeve through the limiting sleeve, and the sliding sleeve will then drive the clamping plate to move away from the adjusting rod. The clamping plate and the straight part cooperate to clamp the piston.

[0042] The extension of the limiting sleeve is used to prevent the push ring sleeve from detaching from the guide sleeve;

[0043] Step S63: Suspend the piston rod in the air-cooling equipment to accelerate the cooling of the outer ring of the Glyd ring using air cooling; the suspended piston rod can rotate around its own axis.

[0044] The guide sleeve can prevent the vertically placed calibration fixture from moving downwards.

[0045] In some embodiments of the present invention, in step S7, the degree of jamming when the piston rotates relative to the calibration fixture is used to determine whether the outer ring of the Gladius ring has been completely cooled and shrunk.

[0046] In some embodiments of the present invention, in step S7, the rotation of the calibration fixture is first restricted, and then the extension rod is rotated to drive the piston to rotate through the clamp and the straight part, so that the piston rotates relative to the calibration fixture.

[0047] The embodiments of the present invention have at least the following advantages or beneficial effects:

[0048] First, the use of electric hot air heating solves the problems of increased humidity in the assembly environment and easy rusting of equipment parts caused by water heating, the problem of oil fumes caused by oil heating, and the safety risk of burns from heating with liquids (water and oil).

[0049] Second, after heating the outer ring of the Glyd ring, there is no need to clean the outer ring of the Glyd ring, thus saving time and improving assembly efficiency and pass rate.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0072] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0073] Example 1

[0074] Firstly, please refer to Figure 1 This embodiment provides a component to be installed, including a piston 11 and a piston rod 12 connected to each other. The circumferential side of the piston 11 has a first mounting groove 111 and a second mounting groove 112 for mounting a shaft Glyd ring. The diameter of the end of the piston rod 12 away from the piston 11 is smaller than the diameter of the piston 11.

[0075] Secondly, please refer to Figures 1-3 This embodiment provides an assembly fixture, including a guide sleeve 21 and a push ring sleeve 22.

[0076] The guide sleeve 21 includes a tapered portion 211 and a straight portion 212 connected to each other. The tapered portion 211 has a first hole 2111, and the straight portion 212 has a second hole 2121. The diameter of the second hole 2121 is larger than the diameter of the first hole 2111, and the second hole 2121 communicates with the first hole 2111 to form a stepped hole. The inner wall of the second hole 2121 can slide in contact with the circumferential side surface of the piston 11.

[0077] The push ring 22 has a central hole 221 on one end face and multiple notches 222 distributed in a circle on the other end, so that the inner diameter of the push ring 22 at this end can be varied.

[0078] When using the assembly fixture, first install the O-ring 52 in the second mounting groove 112 and the first mounting groove 111, then put the straight part 212 of the guide sleeve 21 onto the piston 11, put the outer ring 51 of the glyph onto the tapered part 211, and then use the end of the push ring sleeve 22 with the notch 222 to push the outer ring 51 of the glyph from the tapered part 211 onto the straight part 212. After pushing the outer ring 51 of the glyph from the straight part 212, the outer ring 51 of the glyph can automatically enter the first mounting groove 111 or the second mounting groove 112.

[0079] Thirdly, please refer to Figures 1-5 This embodiment provides a calibration fixture, which includes a calibration part 31 and a diameter reduction part 32 connected to each other; the inner diameter of each part of the calibration part 31 is the same, and the inner wall of the calibration part 31 can slide in contact with the circumferential side of the piston 11; the diameter reduction part 32 is flared, and the minimum inner diameter of the diameter reduction part 32 is the same as the inner diameter of the calibration part 31.

[0080] After completing the installation of the outer ring 51 of the Glyd ring, quickly put the calibration fixture on the piston 11 and use the calibration fixture for calibration. The purpose of calibration is to use the principle of thermal expansion and contraction to make the outer ring 51 of the Glyd ring shrink back to its original size (the outer ring 51 of the Glyd ring shrinks back to its original size after cooling).

[0081] Fourthly, please refer to Figures 1-5 This embodiment provides a process for assembling a shaft-mounted Glyd ring, including the following steps:

[0082] Step S1: Clean the assembly environment, assembly fixtures, calibration fixtures, and parts to be assembled;

[0083] Cleaning the assembly environment includes cleaning the assembly table;

[0084] The cleaning process for parts to be assembled includes cleaning the piston 11 and inspecting the mounting surface of the piston 11.

[0085] Step S2: Install O-rings 52 in the second mounting groove 112 and the first mounting groove 111;

[0086] Step S3: Fit the straight part 212 of the guide sleeve 21 onto the piston 11;

[0087] Step S4: Heating the outer ring 51 of the Gladley ring with electric hot air, including:

[0088] Place the outer ring 51 of the Gladley ring (make sure to check that it does not have an O-ring 52) into the electric heating drying oven by hanging it, set the temperature of the electric heating drying oven to 95℃, and heat at a constant temperature for 30 minutes.

[0089] When multiple outer rings 51 of a glyph are heated at one time, a gap of 10 mm is made between the multiple outer rings 51 of the glyph.

[0090] Step S5, Installing the outer ring 51 of the Glyd ring, includes: taking one heated outer ring 51 from the electric heating drying oven, quickly placing it on the conical part 211, immediately using the push ring sleeve 22 to quickly push the outer ring 51 of the Glyd ring, assembling the outer ring 51 of the Glyd ring into the first mounting groove 111 or the second mounting groove 112, quickly removing the push ring sleeve 22 and the guide sleeve 21, rotating the outer ring 51 of the Glyd ring two turns, so that the O-ring 52 accurately contacts the corresponding groove of the outer ring 51 of the Glyd ring (the outer ring 51 of the Glyd ring has a groove for contacting the O-ring 52).

[0091] Step S6: Use a calibration fixture to calibrate the outer ring 51 of the Glyd ring. This includes quickly placing the calibration fixture on the piston 11 after the installation of the outer ring 51 of the Glyd ring is completed, and using the calibration fixture for calibration. The purpose of calibration is to use the principle of thermal expansion and contraction to make the outer ring 51 of the Glyd ring shrink back to its original size (the outer ring 51 of the Glyd ring shrinks back to its original size after cooling).

[0092] Step S7: Assembly inspection, including after the outer ring 51 of the Glyd ring has completely shrunk, removing the calibration fixture, checking whether there are scratches or other defects on the surface of the outer ring 51 of the Glyd ring, and checking whether the protrusion of the outer ring 51 of the Glyd ring is uniform and meets the dimensional requirements.

[0093] In summary, the shaft-mounted Glyd ring assembly process provided in this embodiment has at least the following beneficial effects:

[0094] First, the use of an electric heating drying oven (electric hot air heating) solves the problems of increased humidity in the assembly environment and easy rusting of equipment parts caused by water heating, oil fumes, and the safety risks of burns from heating with liquids (water and oil).

[0095] Second, after heating the outer ring 51 of the Glyd ring, there is no need to clean the outer ring 51 of the Glyd ring, so as to save time, improve assembly efficiency and pass rate.

[0096] Third, the bottleneck problem of heating the outer ring 51 of the Glyd ring during the batch assembly process has been solved. An electric heating forced-air drying oven can simultaneously heat multiple Glyd rings 51 of different specifications (the heating equipment capacity can reach more than 50 pieces). At the same time, the electric heating forced-air drying oven has a constant temperature insulation function, ensuring uniform heating temperature of the outer ring 51. Damage to the outer ring 51 of the Glyd ring is virtually nonexistent during batch assembly.

[0097] Example 2

[0098] Please refer to Figures 1 to 7 Regarding the assembly process of the shaft-mounted Glyd ring, the difference between this embodiment and Embodiment 1 is as follows:

[0099] In step S3, when the straight portion 212 of the guide sleeve 21 is fitted onto the piston 11, the following steps are taken: first, the adjusting fixture is placed at the bottom of the second hole 2121 of the straight portion 212, and then the straight portion 212 is fitted onto the piston 11.

[0100] The adjustment fixture includes a first pad 41, a second pad 42, and an adjustment rod 43.

[0101] The diameters of the first pad 41 and the second pad 42 are both larger than the diameter of the first hole 2111. The first pad 41 and the second pad 42 are arranged in parallel. The adjusting rod 43 is used to adjust the distance between the first pad 41 and the second pad 42. Specifically, the adjusting rod 43 is threadedly connected to the first pad 41, and one end of the adjusting rod 43 is rotatably connected to the second pad 42. Rotating the adjusting rod 43 adjusts the distance between the first pad 41 and the second pad 42.

[0102] In step S5, installing the outer ring 51 of the Glydring includes: installing the outer ring 51 of the Glydring in the second mounting groove 112 and installing the outer ring 51 of the Glydring in the first mounting groove 111;

[0103] When installing the outer ring 51 of the Glydring in the second mounting slot 112, the following is included:

[0104] Take one heated Glyd ring outer ring 51 from the electric heating drying oven and quickly place it on the conical part 211. Immediately use the push ring sleeve 22 to quickly push the Glyd ring outer ring 51 to assemble it into the second mounting groove 112. Quickly remove the push ring sleeve 22 and the guide sleeve 21, and rotate the Glyd ring outer ring 51 two turns to make the O-ring 52 accurately contact the corresponding groove of the Glyd ring outer ring 51.

[0105] When installing the outer ring 51 of the Glydring in the first mounting slot 111, the following is included:

[0106] Rotate the adjusting rod 43 to adjust the distance between the first pad 41 and the second pad 42 to expose the first mounting groove 111. Take out one of the heated outer rings 51 from the electric heating drying oven and quickly place it on the conical part 211. Immediately use the push ring sleeve 22 to quickly push the outer ring 51 to assemble it into the first mounting groove 111. Rotate the outer ring 51 two turns to make the O-ring 52 accurately contact the corresponding groove of the outer ring 51.

[0107] When the adjusting rod 43 is rotated, pressure can be applied to the first pad 41 and the second pad 42 through the cooperation of the piston 11 and the guide sleeve 21, so as to prevent the first pad 41 and the second pad 42 from rotating with the adjusting rod 43, thereby easily adjusting the distance between the first pad 41 and the second pad 42 by rotating the adjusting rod 43.

[0108] By adjusting the tooling settings, it is easier to install the outer ring 51 of the Glyd ring in the second mounting slot 112 and the first mounting slot 111.

[0109] Example 3

[0110] Please refer to Figures 1-10 Regarding the assembly process of the shaft-mounted Glyd ring, the difference between this embodiment and Embodiment 2 is as follows:

[0111] The adjustment fixture also includes an extension rod 44, a sliding sleeve 45, a connecting rod 46, a slider 47, a clamping plate 48, and a limiting sleeve 49.

[0112] The extension rod 44 is fixedly connected to the adjusting rod 43, and the extension rod 44 can extend through the center hole 221 of the push ring sleeve 22 to the outside of the push ring sleeve 22.

[0113] The sliding sleeve 45 is slidably connected to the extension rod 44.

[0114] One end of the connecting rod 46 is hinged to the sliding sleeve 45, and the other end passes through the first pad 41 and is hinged to the slider 47.

[0115] The slider 47 is slidably connected to the second pad 42.

[0116] One end of the clamping plate 48 is fixed to the slider 47, and the other end passes through the second pad 42 and can extend into the piston 11.

[0117] The limiting sleeve 49 is threaded to one end of the extension rod 44. The limiting sleeve 49 is in contact with one end of the sliding sleeve 45. The limiting sleeve 49 has an extension portion 491, the diameter of which is larger than the diameter of the central hole 221.

[0118] In step S6, when calibrating the outer ring 51 of the Glydette using the calibration fixture, the following steps are included:

[0119] Step S61: After completing the installation of the outer ring 51 of the Glyd ring, keep the push ring sleeve 22, guide sleeve 21 and piston 11 connected, so that the reduced diameter part 32 of the calibration fixture faces the piston 11, and put the calibration fixture on the piston 11 from the piston rod 12 end.

[0120] Step S62: Thread the limiting sleeve 49 onto the extension rod 44, and screw the limiting sleeve 49. The limiting sleeve 49 pushes the sliding sleeve 45, and the sliding sleeve 45 then drives the clamping plate 48 to move away from the adjusting rod 43. The clamping plate 48 and the straight part 212 cooperate to clamp the piston 11.

[0121] The extension 491 of the limiting sleeve 49 is used to prevent the push ring sleeve 22 from disengaging from the guide sleeve 21.

[0122] Step S63: Suspend the piston rod 12 in the air-cooling equipment and use air cooling to accelerate the cooling of the outer ring 51 of the Glyd ring; the piston rod 12 is rotatably connected to the air-cooling equipment, and the suspended piston rod 12 can rotate around its own axis.

[0123] The extension section 491 can prevent the push ring sleeve 22 from disengaging from the guide sleeve 21, and the guide sleeve 21 can prevent the vertically placed correction fixture from moving downward.

[0124] In step S7, to confirm whether the outer ring 51 of the Glyd ring has completely shrunk, the rotation of the calibration fixture is first restricted, and then the extension rod 44 is rotated. The piston 11 is rotated through the clamping plate 48 and the straight part 212. The degree of jamming when the piston 11 rotates relative to the calibration fixture is used to determine whether the outer ring 51 of the Glyd ring has completely shrunk. If the degree of jamming when the piston 11 rotates relative to the calibration fixture is slight, it is determined that the outer ring 51 of the Glyd ring has completely shrunk; otherwise, it has not completely shrunk.

[0125] In summary, the shaft-mounted Glyd ring assembly process provided in this embodiment has at least the following beneficial effects:

[0126] First, during calibration, there is no need to disassemble the push ring sleeve 22 and the guide sleeve 21, which can improve efficiency.

[0127] Second, during calibration, the use of suspended air cooling can improve the cooling efficiency of the outer ring 51 of the Glyd ring, reduce the time occupied by the corresponding calibration fixture, and the waiting time of the assembly fixture used in conjunction with the calibration fixture.

[0128] Third, when confirming whether the outer ring 51 of the Glyd ring has completely shrunk, the degree of sticking when the piston 11 rotates relative to the calibration fixture is used to determine whether the outer ring 51 of the Glyd ring has completely shrunk, which is more intuitive than the timing method.

[0129] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Without conflict, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
