Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring installation, and more specifically to a sealing ring adjustment device for a new energy precision servo actuator. Background Art

[0002] The action principle of the new energy precision servo actuator is that the hydraulic oil in the servo hydraulic actuator reciprocates to push the piston rod to move, realizing the control of the speed, direction, displacement and force of the load. The new energy precision servo actuator has been widely used in new energy vehicles, aerospace, aviation, power generation, steelmaking, shipbuilding, material testing and other fields. Its stability and safety are irreplaceable in the fields of experiments, production, testing and other fields.

[0003] New energy precision servo actuators work in high temperature and high pressure environments for a long time. Due to long-term movement, the end cover sealing ring is often fatigued and damaged and needs to be replaced frequently. The installation of the end cover sealing ring is an important process that is inevitable for actuator maintenance. For the installation and maintenance of the end cover sealing ring of the actuator, there is currently no perfect and safe installation method to ensure the success rate of the sealing ring installation.

[0004] In laboratories and workshops, maintenance workers usually force the end cover sealing ring into the actuator based on their experience and the feel of their hands. This installation method of squeezing and expanding the sealing ring requires a long time to recover to its original shape, as the sealing ring is squeezed and deformed, and sometimes it cannot even be restored to its original shape. As a result, the sealing ring is often pushed out of the cylinder after installation, causing damage to the actuator. Utility Model Content

[0005] The utility model aims to provide a sealing ring adjustment device for a new energy precision servo actuator to solve the problems in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model is implemented by adopting the following technical solutions:

[0007] A new energy precision servo actuator sealing ring adjustment device, comprising:

[0008] The guide support assembly 100 includes a guide ring 110 and a guide sleeve 120. The guide ring 110 is an annular member.

[0009] The movable set 200 comprises a set 210, a slider 220 and an elastic ring 230. The set 210 is an annular component formed by a plurality of arc blocks 211 which are arranged around the periphery of the guide ring 110 and are not connected to each other. The number of the sliders 220 is the same as the number of the arc blocks 211. The sliders 220 are arranged along the radial direction of the set 210, one end of which is vertically connected to the inner side of the arc block 211, and the other end of which passes through the guide groove 130 and extends into the guide ring 110.

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the utility model is described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, but not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 , Figure 2This embodiment provides a new energy precision servo actuator sealing ring adjustment device, including: a guide support assembly 100, a moving assembly 200 and a connecting rod reamer 300.

[0026] The guide support assembly 100 includes a guide ring 110 and a guide sleeve 120. The guide ring 110 is an annular member. The side edge of the guide ring 110 is circumferentially provided with radially extending guide grooves 130. The guide grooves 130 penetrate the guide ring 110 to connect the inner ring and the outer ring of the guide ring 110. The guide sleeve 120 is coaxially arranged with the guide ring 110 and is connected to the guide ring 110 via a support rod 140. The end of the guide sleeve 120 is provided with a threaded sleeve 150 with an internal thread.

[0027] In this embodiment, the guide ring 110 is composed of a first annular member 111 and a second annular member 112 that are relatively arranged. The first guide groove 131 and the second guide groove 132 that are distributed along the circumferential direction are arranged on the opposite end surfaces of the first annular member 111 and the second annular member 112. The first guide groove 131 and the second guide groove 132 extend radially along the first annular member 111 and the second annular member 112. The first guide groove 131 and the second guide groove 132 correspond one-to-one to form the guide groove 130.

[0028] The moving assembly 200 includes an assembly 210 , a slider 220 and an elastic ring 230 .

[0029] The assembly 210 is an annular component formed by a plurality of arc-shaped blocks 211 disposed around the periphery of the guide ring 110 and not connected to each other. The outer side surface of the assembly 210 is provided with a surrounding groove 212 .

[0030] The number of the sliders 220 is the same as the number of the arc blocks 211. The sliders 220 are arranged along the radial direction of the set 210, one end of which is vertically connected to the inner side of the arc block 211, and the other end passes through the guide groove 130 and extends into the guide ring 110, and can slide radially in the guide groove 130. A roller 240 is arranged on one end of the slider 220 located inside the guide ring 110, and a plurality of the rollers 240 surround a circular space.

[0031] The elastic annular member 230 is sleeved in the groove 212 on the outer side of the assembly 210 to provide a centripetal force of 500N for the assembly 210 .

[0032] The connecting rod reamer 300 includes a conical head 310 and a connecting rod 320. The connecting rod 320 is connected to the top end of the conical head 310. The connecting rod 320 is provided with an external thread. One end of the connecting rod 320 passes through the guide ring 110 and the guide sleeve 120 in sequence, so that the bottom surface of the conical head 310 is retained on one side of the first ring member 110. The external thread of the connecting rod 320 is threadedly matched with the threaded sleeve 150 at the end of the guide sleeve 120.

[0033] In order to facilitate the rotation of the connecting rod reamer 300, in this embodiment, the connecting rod reamer 300 also includes a handle member 330, and the handle member 330 is movably mounted on the end of the connecting rod 320 away from the conical head 310, and cooperates with the connecting rod 320 through a keyway to limit relative rotation.

[0034] The working principle of a new energy precision servo actuator sealing ring adjustment device provided in this embodiment is as follows:

[0035] By rotating the connecting rod 310 of the connecting rod reamer 300, the top thread of the connecting rod 310 is threadedly matched with the threaded sleeve 150 at the end of the guide sleeve 120, so that the rotation of the connecting rod reamer 300 is converted into linear motion, and the forward / reverse rotation of the connecting rod reamer 300 achieves the forward / backward movement of the connecting rod reamer 300. During the forward / backward movement of the connecting rod reamer 300, the conical head 310 of the connecting rod reamer 300 squeezes the roller 240 at the end of the slider 220 of the movable set 200. The set 210 is expanded radially outward, and at the same time, the elastic ring member 230 installed in the groove 212 on the side of the set 210 applies a coaxial centripetal force to the set 210 to achieve expansion and locking of the set 210; after the sealing ring of the new energy precision servo actuator is installed, the set 210 is placed in the sealing ring circle, and the connecting rod reamer 300 cooperates with the elastic ring member 230 to expand the set 210, physically stretch the sealing ring, and restore the sealing ring to its original shape, thereby ensuring that the sealing ring meets the installation requirements.

[0036] After the assembly 210 has supported the seal for a certain period of time, the sealing ring has completely recovered its original shape. At this time, the connecting rod reamer 300 is rotated in the opposite direction, and the conical head 310 no longer squeezes the roller 240. Under the action of the elastic ring 230, the assembly 210 contracts radially inward. At this time, the entire device can be removed to complete the installation and adjustment of the sealing ring.
