Swing type hydraulic actuator

Abstract

This utility model relates to the field of hydraulic actuators and provides a swing-type hydraulic actuator. The actuator includes: a body; an oil inlet disposed on one side of the body, and a connecting pipe fixedly disposed at one end of the oil inlet. In use, by inserting the sleeve into the interior of the connecting pipe, the two limiting plates are further inserted into the interior of the two fixing plates. The two fixing blocks are squeezed by the inner walls of the two fixing plates, which further causes the two second sleeve rods to slide into the interior of the two first sleeve rods, thus fixing the sleeve and the connecting pipe together. During disassembly, by pressing the two fixing blocks upward, the two fixing blocks are further slid into the interior of the two limiting plates. At this time, the sleeve can be removed from the connecting pipe. Thus, when using the actuator, the installation method between the oil chamber pipe and the body is simple, and installation and disassembly do not require turning screws, reducing the maintenance time of the actuator.

Description

Technical Field

[0001] This application relates to the field of hydraulic actuators, and in particular to a swing-type hydraulic actuator. Background Technology

[0002] In the field of hydraulic technology, swing hydraulic actuators are widely used in various mechanical equipment as driving devices. Traditional swing hydraulic actuators have a relatively simple structure. Their main function is to drive the actuator to complete the swing motion of an object through hydraulic oil. Typically, such actuators include a hydraulic chamber, a hydraulic oil inlet, and an output end that drives the swing.

[0003] Hydraulic actuators transmit power through hydraulic oil in the oil chamber. The hydraulic oil enters the oil chamber through the inlet and, within the oil chamber, pushes the actuator's piston or output end to perform corresponding actions through hydraulic pressure. Utilizing the high-pressure characteristics of hydraulic oil, it can provide strong driving force to drive the output end to complete the required swinging motion. In traditional swing-type hydraulic actuators, the connection between the oil chamber and the actuator is usually fixed with screws. Although this screw connection method is relatively simple, it requires certain operating steps and time during installation and disassembly, and is especially troublesome during maintenance. Secondly, the screw connection is prone to loosening, which may lead to poor sealing or leakage problems over long-term use, affecting the normal operation of the actuator. Moreover, the quality of the hydraulic oil largely determines the working efficiency and lifespan of the actuator. If the oil contains impurities, these impurities may cause wear on the components in the hydraulic system, thereby affecting the operation of the entire system. Utility Model Content

[0004] This application provides a swing-type hydraulic actuator. When using the actuator, the installation method between the oil chamber pipe and the body is simple, and installation and disassembly are carried out without turning screws, which reduces the maintenance time of the actuator. It also filters impurities in the oil to prevent impurities from damaging the actuator and increases the service life of the actuator.

[0005] To achieve the above objectives, this application adopts the following technical solution: a swing-type hydraulic actuator, the actuator comprising:

[0006] ontology;

[0007] An oil inlet is located on one side of the main body, and a connecting pipe is fixedly installed at one end of the oil inlet;

[0008] Two fixing plates are fixedly installed on the outer surface of the connecting pipe, and a limiting plate is movably embedded in the inner wall of each fixing plate;

[0009] Two support plates are fixedly installed on one side of the two limiting plates, and sleeves are fixedly installed on the opposite side of the outer surface of the two support plates.

[0010] As a further improvement of this application: a first sleeve rod is fixedly provided on one side of the inner wall of each of the two limiting plates, and a second sleeve rod is movably embedded in the inner wall of each of the two first sleeve rods.

[0011] As a further improvement of this application: a fixing block is fixedly provided on one side of each of the two second sleeve rods, and a spring is movably sleeved on the outer surface of each of the two second sleeve rods.

[0012] As a further improvement of this application: the two fixing blocks are movably embedded in the inner walls of the two limiting plates, and the sleeve is movably embedded in the inner wall of the connecting pipe.

[0013] As a further improvement of this application: a sealing gasket is provided on the inner wall of the connecting pipe, and an oil cavity pipe is installed on one side of the sleeve.

[0014] As a further improvement of this application: a plurality of round rods are fixedly provided on one side of the connecting pipe, and an mounting plate is movably embedded on the outer surface of the plurality of round rods.

[0015] As a further improvement of this application: the sleeve is fixedly embedded with a baffle, and a filter screen is fixedly installed on the inner wall of the mounting plate.

[0016] As a further improvement of this application: a plurality of through holes are provided on one side of the mounting plate, and any one of the round rods matches any one of the through holes.

[0017] Compared with the prior art, the advantages and positive effects of this application are as follows:

[0018] This application, by inserting the sleeve into the interior of the connecting pipe, and the elasticity of the sealing gasket, further allows the two limiting plates to be inserted into the interior of the two fixing plates. The two second sleeve rods can slide inside the two first sleeve rods respectively. The two fixing blocks are squeezed by the inner walls of the two fixing plates, further causing the two second sleeve rods to slide into the interior of the two first sleeve rods, thus fixing the sleeve and the connecting pipe together in one step. During disassembly, by pressing the two fixing blocks upward, the two fixing blocks are further slid into the interior of the two limiting plates. At this time, the sleeve can be removed from the connecting pipe. Therefore, when using the actuator, the installation method between the oil chamber pipe and the body is simple, and installation and disassembly do not require turning screws, reducing the maintenance time of the actuator.

[0025] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways than those described herein, and therefore this application is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1, such as Figure 1 , Figure 2 and Figure 5As shown, this application provides a swing-type hydraulic actuator, which includes: a body 1; an oil inlet 2, disposed on one side of the body 1, with a connecting pipe 201 fixedly disposed at one end of the oil inlet 2; two fixing plates 202, fixedly disposed on the outer surface of the connecting pipe 201, with a limiting plate 203 movably embedded in the inner wall of each of the two fixing plates 202; and two support plates 204, respectively fixedly disposed on one side of the two limiting plates 203, with a sleeve 205 fixedly disposed on the opposite side of the outer surface of the two support plates 204. A first sleeve rod 206 is fixedly installed on one side of each wall. A second sleeve rod 207 is movably embedded in the inner wall of each of the two first sleeve rods 206. A fixing block 208 is fixedly installed on one side of each of the two second sleeve rods 207. A spring 209 is movably sleeved on the outer surface of each of the two second sleeve rods 207. The two fixing blocks 208 are movably embedded in the inner wall of the two limiting plates 203. A sleeve 205 is movably embedded in the inner wall of the connecting pipe 201. A sealing gasket 211 is provided on the inner wall of the connecting pipe 201. An oil cavity pipe 210 is installed on one side of the sleeve 205.

[0028] By adopting the above technical solution, the two limiting plates 203 can slide on the inner walls of the two fixing plates 202 respectively, and the sleeve 205 can slide inside the sealing gasket 211. By inserting the sleeve 205 into the connecting pipe 201, the sealing gasket 211 has elasticity. At this time, the sealing gasket 211 is fitted on the outer surface of the sleeve 205 to prevent oil leakage. This further allows the two limiting plates 203 to be inserted into the interior of the two fixing plates 202. The two second sleeve rods 207 can slide inside the interior of the two first sleeve rods 206 respectively. One side of the two fixing blocks 208 is inclined, and the two fixing blocks 208 are squeezed by the inner walls of the two fixing plates 202. The first step causes the two second sleeve rods 207 to slide into the interior of the two first sleeve rods 206, compressing the two springs 209. When the two fixing blocks 208 slide out of the interior of the two fixing plates 202, the elastic force generated by the two springs 209 compresses the two fixing blocks 208, causing the two fixing blocks 208 to slide out of the interior of the two limiting plates 203, locking the positions of the two limiting plates 203, and further fixing the sleeve 205 and the connecting pipe 201 together. During disassembly, by pressing the two fixing blocks 208 upward, the two fixing blocks 208 are further slid into the interior of the two limiting plates 203. At this time, the sleeve 205 can be removed from the connecting pipe 201.

[0029] Example 2, as Figure 2 and Figure 3As shown, a plurality of round rods 3 are fixedly installed on one side of the connecting pipe 201, and an mounting plate 301 is movably embedded on the outer surface of the plurality of round rods 3. A baffle 304 is fixedly embedded in the sleeve 205. A filter screen 302 is fixedly installed on the inner wall of the mounting plate 301. A plurality of through holes 303 are opened on one side of the mounting plate 301, and any round rod 3 matches any through hole 303.

[0030] By adopting the above technical solution, the oil inside the oil chamber tube 210 enters the body 1 through the oil inlet 2, driving the output end of the actuator. The oil passes through the filter screen 302, which filters impurities in the oil. When disassembling the body 1 and the oil chamber tube 210, the through hole 303 can be removed from the inside of the sleeve 205. At this time, the impurities on the filter screen 302 can be cleaned. The multiple round rods 3 can slide on the inner wall of the through hole 303. When the sleeve 205 is inserted into the connecting pipe 201, the multiple round rods 3 are inserted into the multiple through holes 303. One side of the mounting plate 301 is tightly attached to one side of the baffle 304, fixing the position of the mounting plate 301 and further fixing the filter screen 302 inside the sleeve 205.

[0031] Working principle: When using the hydraulic actuator, the two limit plates 203 can slide on the inner walls of the two fixed plates 202 respectively, and the sleeve 205 can slide inside the sealing gasket 211. By inserting the sleeve 205 into the connecting pipe 201, the sealing gasket 211, which has elasticity, is fitted onto the outer surface of the sleeve 205 to prevent oil leakage. This further allows the two limit plates 203 to be inserted into the two fixed plates 202, and the two second sleeve rods 207 can slide inside the two first sleeve rods 206 respectively. One side of the two fixed blocks 208 is inclined. The fixing block 208 is pressed by the inner walls of the two fixing plates 202, which further causes the two second sleeve rods 207 to slide into the interior of the two first sleeve rods 206, compressing the two springs 209. When the two fixing blocks 208 slide out of the interior of the two fixing plates 202, the elastic force generated by the two springs 209 compresses the two fixing blocks 208, causing the two fixing blocks 208 to slide out of the interior of the two limiting plates 203, locking the positions of the two limiting plates 203, and further fixing the sleeve 205 and the connecting pipe 201 together. During disassembly, by pressing the two fixing blocks 208 upwards, further... Two fixing blocks 208 slide into the interior of two limiting plates 203. At this time, the sleeve 205 can be removed from the connecting pipe 201. This simplifies the installation of the oil chamber pipe 210 and the body 1 during actuator use, eliminating the need to rotate screws for installation and disassembly, thus reducing actuator maintenance time. During actuator use, oil inside the oil chamber pipe 210 enters the body 1 through the oil inlet 2, driving the actuator's output. The oil passes through the filter screen 302, which filters impurities from the oil. Furthermore, when disassembling the body 1 and the oil chamber pipe 210, [the following steps can be taken]. The through hole 303 can be removed from the inside of the sleeve 205. At this time, the impurities on the filter screen 302 can be cleaned. The multiple round rods 3 can slide on the inner wall of the through hole 303. When the sleeve 205 is inserted into the connecting pipe 201, the multiple round rods 3 are inserted into the multiple through holes 303. One side of the mounting plate 301 is tightly attached to one side of the baffle 304 to fix the position of the mounting plate 301. The filter screen 302 is further fixed inside the sleeve 205. Thus, when using the actuator, impurities in the oil are filtered to prevent impurities from damaging the actuator and to improve the service life of the actuator.
