Description

Technical Field

[0001] The present application relates to the technical field of push rod motor protection, and in particular to a push rod motor installation protection device. Background Art

[0002] A push rod motor, also known as a linear motor or linear motor, is a common motor used to perform linear motion. It is usually used in automation equipment or industrial applications that require precise control of linear displacement. The structure of this motor usually includes a motor, a lead screw, a nut and other components. The motor rotates to drive the lead screw and nut pair to convert rotary motion into linear motion.

[0003] During the operation of the existing push rod motor, the output rod end of the push rod is easy to roll the contact object into the push rod motor. Moreover, since the push rod motor is often used in a humid environment, it is easy for water to condense at the output rod end and enter the inside of the push rod motor, causing corrosion to the device.

[0004] After searching, for example, the patent with publication number CN114172299A specifically discloses a push rod motor installation protection device. The patent wipes the output rod end of the push rod motor body with a sponge block to remove condensed water droplets on the surface of the output rod end of the push rod motor body.

[0005] However, after being used for a certain period of time, the sponge in the above patent absorbs a certain amount of water, and it is difficult to remove the water droplets condensed on the surface of the output rod end. At this time, when the output rod of the motor is extended and retracted again, the adsorbed water on the sponge will be carried out, and the carried water droplets will enter the interior of the push rod motor and cause corrosion to the device. Therefore, it is necessary to provide a push rod motor installation protection device to solve the above problem.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0007] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide a push rod motor installation protection device to ensure the water absorption of the sponge ring and prevent the output shaft from carrying out the water adsorbed on the sponge ring and causing corrosion to the device.

Detailed implementation manners

[0031] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine with the embodiments to detail this application.

[0032] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0033] Such as Figure 1As shown in the figure, the present application provides a protective device for installing a push rod motor, including the body 1 of the push rod motor. The body 1 has an output shaft 11. At the same time, a protective mechanism 2 is provided on the outer side of one end of the output shaft 11 close to the body 1. The protective mechanism 2 is used to protect and clean the output shaft 11.

[0034] As Figures 2 - 3 shown, the protective mechanism 2 has a fixing member 21 installed on the outer side of the body 1. The shape of the fixing member 21 is the same as the shape of the outer shell of the body 1. The fixing member 21 has a first fixing plate 211 and a second fixing plate 212 that can be assembled. One end between the first fixing plate 211 and the second fixing plate 212 is hinged, so that the fixing member 21 can be opened and closed;

[0035] At the same time, the other end of the second fixing plate 212 is connected with a screw rod 213. A threaded sleeve 215 is threadedly connected to the screw rod 213. And a clamping plate 214 is fixedly installed at the other end of the first fixing plate 211. An installation groove (not marked in the figure) is opened at one side end of the clamping plate 214. In the present application, when the first fixing plate 211 and the second fixing plate 212 are assembled, the screw rod 213 can be rotated into the installation groove;

[0036] And protective plates 22 are fixedly installed at the side ends of the first fixing plate 211 and the second fixing plate 212 away from the body 1. Clamping plates 23 are fixedly installed on the opposite surfaces of the protective plates 22. In the present application, the clamping plates 23 are arranged in an arc shape. Therefore, when the first fixing plate 211 and the second fixing plate 212 are assembled, the two groups of clamping plates 23 at this time are circular and are attached to the outer side of the end of the output shaft 11, so as to protect the connection between the body 1 and the output shaft 11;

[0037] It should be noted that rubber pads are installed on the opposite surfaces of the clamping plates 23. The rubber pads can improve the sealing performance of the connection between the clamping plates 23 and the output shaft 11.

[0038] Therefore, when installing the protective mechanism 2, first loosen the threaded sleeve 215 to the outer end of the screw rod 213, then open the first fixing plate 211 and the second fixing plate 212 and sleeved them on the outer shell of the body 1 to make them fit. At this time, rotate the screw rod 213 into the installation groove of the clamping plate 214, and then tighten the threaded sleeve 215. At the same time, the clamping plates 23 will be assembled, and the protective plates 22 will be sleeved on the outer side of the output shaft 11.

[0039] As Figures 2 - 4 shown, a cleaning ring 24 is arranged inside the protective plate 22. The cleaning ring 24 is located on the side of the clamping plate 23 away from the fixing member 21. A sponge ring 25 is arranged inside the cleaning ring 24. The sponge ring 25 cooperates with the output shaft 11. It can be understood that when the sponge ring 25 is sleeved on the outer side of the output shaft 11, it will be attached to the surface of the output shaft 11;

[0040] To prevent the sponge ring 25 from slipping out of the cleaning ring 24, a retaining ring 242 is fixedly installed at one end of the cleaning ring 24. The retaining ring 242 cooperates with the output shaft 11. And an extension ring 244 is installed at the other end of the cleaning ring 24. The width of the extension ring 244 is greater than the width of the cleaning ring 24, so as to protect both sides of the sponge ring 25. When installing, since the sponge ring 25 can be deformed, the sponge ring 25 can be squeezed and inserted into the retaining ring 242.

[0041] To facilitate the installation of the cleaning ring 24 into the protective plate 22, a card slot 221 is opened at one end of the protective plate 22 away from the fixing member 21. At the same time, engaging blocks 241 are fixedly installed at both ends of the cleaning ring 24. The engaging blocks 241 and the card slot 221 cooperate with each other. Therefore, when installing the cleaning ring 24, first sleeve the sponge ring 25 and the cleaning ring 24 on the output shaft 11, then push the cleaning ring 24 to make the engaging blocks 241 snap into the card slot 221, and finally push it until it stops.

[0042] Thus, when the output shaft 11 expands and contracts, the condensed water droplets on the output shaft 11 are removed by the sponge ring 25.

[0043] At the same time, a pressing member 26 is arranged on the side of the cleaning ring 24 away from the clamping plate 23. The pressing member 26 is used to squeeze the sponge ring 25. The pressing member 26 has a pressing plate 261. An installation hole 262 is opened on the pressing plate 261. The installation hole 262 is adapted to the output shaft 11. The pressing plate 261 can be sleeved on the output shaft 11 through the installation hole 262;

[0044] And a pressing ring 263 is fixedly installed at one end of the pressing plate 261 close to the cleaning ring 24. The pressing ring 263 is coaxially arranged with the installation hole 262. In this application, the diameter of the pressing ring 263 is smaller than the diameter of the extension ring 244. Therefore, the pressing ring 263 can slide in the extension ring 244, and the pressing ring 263 is attached to the sponge ring 25 under normal conditions.

[0045] At the same time, a plurality of groups of cooperation holes 222 are also opened at one end of the protective plate 22 away from the fixing member 21. And a plurality of groups of cooperation rods 264 are fixedly installed at one end of the pressing plate 261 close to the pressing ring 263. The cooperation rods 264 cooperate with the cooperation holes 222. Therefore, after the cleaning ring 24 and the sponge ring 25 are installed into the protective plate 22, the pressing plate 261 is sleeved on the output shaft 11 until the cooperation rods 264 are inserted into the cooperation holes 222.

[0046] In this application, a hole 243 is penetrated and opened at the lower end of the cleaning ring 24.

[0047] Therefore, after the push rod motor has been used for a period of time, the staff manually pushes the pressing plate 261 towards the cleaning ring 24, causing the mating rod 264 to slide within the mating hole 222. At the same time, the pressing ring 263 will squeeze the sponge ring 25, forcing the water inside the sponge ring 25 to be extruded outwards and flow outwards through the holes 243 on the cleaning ring 24, thereby ensuring the water absorption of the sponge ring 25 and preventing the water adsorbed on the sponge ring 25 from being carried out again when the output shaft 11 extends and retracts, and then entering the interior of the push rod motor, so as not to cause corrosion to the device.

[0048] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
