Description

Technical Field

[0001] This utility model relates to the field of servo electric cylinders, specifically a dustproof servo electric cylinder. Background Technology

[0002] Servo electric cylinders are modular products that integrate servo motors and electric cylinders. They convert the rotary motion of the servo motor into the linear motion of the lead screw, achieving precise speed and position control. They are characterized by low cost and flexible configuration.

[0003] Existing servo electric cylinders, such as the one proposed in patent application number "CN202221369909.0", consist of a servo motor, an electric cylinder body, a transmission device, and a feedback device. The electric cylinder body houses the transmission device, and the transmission device is equipped with a feedback device, which includes an encoder. The encoder is connected to a human-machine interface (HMI) for detecting and controlling the servo electric cylinder. By setting an encoder connected to the HMI interface, the position of the push rod can be monitored in real time, making the push rod movement more accurate, reducing the risk of push rod damage, and providing a simple, safe, and reliable structure.

[0004] However, existing technologies have drawbacks. When the lead screw of the electric cylinder body of the servo electric cylinder slides and extends, the surface of the lead screw is easily contaminated with dust on the outside of the electric cylinder body. The dust can easily slide into the inside of the electric cylinder body with the lead screw, thereby corroding or wearing the internal parts of the electric cylinder body and reducing the life of the servo electric cylinder. Therefore, a dustproof servo electric cylinder is proposed. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] A dustproof servo electric cylinder, such as Figures 1-6 As shown, the device includes a connecting seat 3, which has a structure inside for linking the servo motor 2 and the electric cylinder 1. The electric cylinder 1 and the servo motor 2 are fixedly connected to one side of the connecting seat 3. A lead screw 4 is slidably connected to one end of the electric cylinder 1. A dustproof component for cleaning the side wall of the lead screw 4 is snapped onto one end of the electric cylinder 1. The lead screw 4 passes through the middle of the dustproof component. The dustproof component includes an annular cleaning pad 8, which is snapped onto one end of the electric cylinder 1. The inner wall of the annular cleaning pad 8 is in contact with the outer wall of the lead screw 4. An outer protective plate 10 for pressing and installing the annular cleaning pad 8 is snapped onto one end of the electric cylinder 1. A cleaning brush 15 for cleaning the side wall of the lead screw 4 is fixedly connected to the inner wall of the outer protective plate 10.

[0027] By providing a dustproof component for cleaning the sidewall of the lead screw 4 at one end of the electric cylinder body 1, when the surface of the lead screw 4 is covered with dust and needs cleaning, the lead screw 4 retracts into the electric cylinder body 1. Both the cleaning brush 15 and the annular cleaning pad 8 have sliding friction with the surface of the lead screw 4. The cleaning brush 15 removes filamentous impurities or large impurities from the surface of the lead screw 4, preventing filamentous impurities or large impurities from sticking to the surface of the annular cleaning pad 8 and affecting the cleaning of the annular cleaning pad 8. The annular cleaning pad 8 wipes the sidewall of the lead screw 4, preventing small dust particles from entering the electric cylinder body 1. This servo electric cylinder has a dustproof function, effectively preventing the lead screw 4 from carrying dust into the electric cylinder body 1.

[0028] like Figures 2-6 As shown, the electric cylinder body 1 has multiple sets of slots 5 at one end, which are arranged in a circular array. The cross-sectional shape of each set of slots 5 is "L". Each set of slots 5 has a through slot 6 at one end. Multiple sets of connecting plates 11 are fixed to one side of the outer protective plate 10. Each set of connecting plates 11 has a locking block 12 fixed to its end. The locking block 12 is inserted into the through slot 6 and engaged with the slot 5.

[0029] When installing the outer protective plate 10, align the locking block 12 with the through slot 6 and insert it into one end of the slot 5. Then rotate the outer protective plate 10 at a certain angle so that the locking block 12 slides into the slot 5. The locking block 12 engages with the slot 5, and the connecting plate 11 cannot detach from the electric cylinder body 1, making installation convenient.

[0030] like Figures 2-6 As shown, one end of the electric cylinder body 1 is provided with a slot 7, and a plug 9 is fixedly connected to one side of the annular cleaning pad 8. The plug 9 is inserted into the slot 7. Multiple sets of pressure plates 14 are fixedly connected to one side of the outer protective plate 10. All sets of pressure plates 14 are pressed and cooperated with one side of the annular cleaning pad 8.

[0031] The annular cleaning pad 8 has an opening, which makes it easy to put the annular cleaning pad 8 onto the lead screw 4. The insert block 9 of the annular cleaning pad 8 is inserted into the slot 7 to position and install the annular cleaning pad 8 on the electric cylinder body 1. One side of the annular cleaning pad 8 is squeezed by the outer protective plate 10 to prevent it from falling off.

[0032] like Figures 2-6 As shown, the annular cleaning pad 8 has an annular groove 22 on the side away from the electric cylinder 1. The annular groove 22 fits against the side wall of the lead screw 4. Multiple anti-slip blocks 13 are fixed to the side of the outer protective plate 10.

[0033] The annular groove 22 collects dust, and the presence of the anti-slip block 13 facilitates the unscrewing of the outer protective plate 10.

[0034] like Figure 5 As shown, a retaining ring 16 is snapped onto one side of the outer protective plate 10, and a sealing ring 17 is fixed to one side of the retaining ring 16. One side of the sealing ring 17 is in contact with the side wall of the lead screw 4.

[0035] The sealing ring 17 is installed on the outer protective plate 10 via the retaining ring 16. The sealing ring 17 is set at an angle to prevent external dust from entering the interior of the outer protective plate 10, and can pre-scrape the surface of the lead screw 4 to reduce the workload of the cleaning brush 15.

[0036] like Figure 1 , Figure 7 As shown, a base 19 is fixedly connected to one side of both the connecting seat 3 and the electric cylinder body 1. Multiple sets of adjusting columns 21 are rotatably connected to the lower end of the base 19, and the multiple sets of adjusting columns 21 are threaded into the adjusting holes 20 of the mounting seat 18.

[0037] The servo electric cylinder is installed through multiple sets of mounting bases 18. The base 19 and the adjusting column 21 integrate the mounting base 18 and the servo electric cylinder. By using a screwdriver or other parts to enter the adjusting hole 20 and turn the adjusting column 21, the height of the adjusting column 21 can be changed, thereby adjusting the installation height of the servo electric cylinder.

[0038] The working principle of the dustproof servo electric cylinder provided by this utility model is as follows:

[0039] By providing a dustproof component for cleaning the sidewall of the lead screw 4 at one end of the electric cylinder body 1, when the surface of the lead screw 4 is contaminated with dust and needs to be cleaned, the lead screw 4 retracts into the electric cylinder body 1. The sealing ring 17 pre-cleans the surface of the lead screw 4, the cleaning brush 15 removes filamentous impurities or large impurities from the surface of the lead screw 4, and the annular cleaning pad 8 wipes the sidewall of the lead screw 4 to prevent small dust particles from entering the electric cylinder body 1. This servo electric cylinder has a dustproof function, effectively preventing the lead screw 4 from carrying dust into the electric cylinder body 1.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
