Description

Technical Field

[0001] This utility model relates to the field of electric cylinder technology, specifically an integrated electric cylinder. Background Technology

[0002] An electric cylinder is a device that converts the rotary motion of an electric motor into linear motion. It is typically designed with a servo motor and a lead screw, and is a mechatronic product. It enables high-precision linear motion control and is an ideal replacement for hydraulic and pneumatic cylinders.

[0003] Traditional electric cylinders are typically assembled from separate components such as a motor, reducer, and lead screw. The independent installation of these multiple parts results in a large overall size, making installation and maintenance inconvenient. Furthermore, traditional electric cylinders have limitations in transmission efficiency, precision control, and heat dissipation, making it difficult to meet the demands of modern industry for efficient, precise, and stable equipment. Utility Model Content

[0004] This invention provides an integrated electric cylinder, which solves the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: It includes a device housing, an inner cavity of which is fitted with a guide bearing; an outer wall of which is fixedly fitted with a servo motor; an inner cavity of which is movably fitted with a guide rod; an outer wall of which is fixedly fitted with an encoder; a power plug; an inner cavity of which is movably fitted with a drive screw; an outer wall of which is fixedly fitted with a telescopic rod; and an outer wall of which is fixedly fitted with a screw nut.

[0006] As a preferred technical solution of this utility model: the guide bearing is embedded in the inner cavity of the equipment housing, and the power output shaft of the servo motor is connected to the outer wall of the drive screw.

[0007] As a preferred technical solution of this utility model: the power plug is electrically connected to the encoder, and the outer wall of the drive screw is rotatably connected to the inner wall of the screw nut.

[0008] As a preferred technical solution of this utility model: the outer wall of the guide rod away from the screw nut is connected to the outer wall of the telescopic rod, the outer wall of the drive screw is provided with a threaded groove, and the inner cavity of the screw nut is equipped with balls.

[0009] As a preferred technical solution of this utility model: the encoder is electrically connected to the power plug, and the drive screw is made of high carbon steel.

[0010] As a preferred technical solution of this utility model: the guide bearing is a high-precision lubricated bearing, and the inner wall of the guide bearing is in contact with the outer wall of the guide rod.

[0011] This utility model has the following beneficial effects:

[0012] 1. This integrated electric cylinder, by incorporating a servo motor mounted on the outer wall of the equipment housing, effectively reduces the overall footprint of the equipment. The servo motor drives the lead screw, which in turn precisely drives the lead screw nut. As the lead screw nut moves, the guide rod also moves accordingly, ultimately achieving effective driving of the telescopic rod. This not only improves the operating efficiency of the equipment but also ensures operational accuracy and reliability.

[0013] 2. This integrated electric cylinder, through an encoder mounted on the outer wall of the equipment housing, can precisely control the rotation of the servo motor. This precise control mechanism enables the servo motor to drive the rotation of the lead screw more accurately. Furthermore, through this fine control of the lead screw rotation, we can achieve precise management of the movement of the lead screw nut. In this way, the extension and retraction length of the telescopic rod can achieve higher precision, thereby ensuring that the telescopic rod can achieve a more accurate effect when performing pushing tasks.

[0014] 3. This integrated electric cylinder reduces the overall length of the equipment by connecting the servo motor to the cylinder body, enabling the equipment to be installed and used under some special working conditions. This makes the equipment suitable for more working conditions, and its small footprint allows it to be installed on a wider variety of machines, greatly improving its applicability.

[0022] In the above structure, the lead screw nut 9 installed on the outer wall of the guide rod 8 and the servo motor 3 installed on the outer wall of the equipment housing 2 drive the drive screw 4 under the action of the servo motor 3. Thus, the drive screw 4 drives the lead screw nut 9 during rotation, thereby driving the telescopic rod 7 to move during the movement of the lead screw nut 9, thereby realizing the unfolding of the equipment.

[0023] In a preferred embodiment: the guide bearing 1 is embedded in the inner cavity of the equipment housing 2, and the power output shaft of the servo motor 3 is connected to the outer wall of the drive screw 4.

[0024] In the above structure, the guide bearing 1 installed in the inner cavity of the equipment housing 2 can guide the movement of the guide rod 8 under the action of the guide bearing 1, so that the guide rod 8 can move smoothly outward from the inner cavity of the equipment housing 2, so as to achieve the ejection effect under the action of the drive screw 4, and thus produce the corresponding working effect.

[0025] In a preferred embodiment: the power plug 6 is electrically connected to the encoder 5, and the outer wall of the drive screw 4 is rotatably connected to the inner wall of the screw nut 9.

[0026] In the above structure, the encoder 5 installed on the outer wall of the equipment housing 2 can precisely control the rotation of the servo motor 3 according to preset parameters and feedback signals, thereby enabling precise control of the extension and retraction of the telescopic rod 7 and achieving a better driving effect.

[0027] In a preferred embodiment: the outer wall of the guide rod 8 away from the lead screw nut 9 is connected to the outer wall of the telescopic rod 7, the outer wall of the drive lead screw 4 is provided with a threaded groove, and the inner cavity of the lead screw nut 9 is equipped with balls.

[0028] In the above structure, by the threaded groove on the outer wall of the drive screw 4 and the ball installed in the inner cavity of the screw nut 9, the screw nut 9 can be driven during the rotation of the drive screw 4, so that the ball can move in the threaded groove on the outer wall of the drive screw 4, thereby driving the telescopic rod 7.

[0029] In a preferred embodiment, the encoder 5 is electrically connected to the power plug 6, and the drive screw 4 is made of high carbon steel.

[0030] In the above structure, the power plug 6 installed on the outer wall of the servo motor 3 can supply power to the encoder 5, thereby adjusting the rotation of the servo motor 3 under the action of the encoder 5, so as to more accurately control the rotation of the drive screw 4, thereby better driving the screw nut 9, and making the extension distance of the telescopic rod 7 more accurate.

[0031] In a preferred embodiment: the guide bearing 1 is a high-precision lubricated bearing, and the inner wall of the guide bearing 1 is in contact with the outer wall of the guide rod 8.

[0032] In the above structure, the guide bearing 1 embedded in the inner cavity of the equipment housing 2 can restrict the movement of the guide rod 8 under the action of the guide bearing 1, so that the guide rod 8 can move smoothly outward from the inner cavity of the equipment housing 2 under the action of the guide bearing 1, thereby smoothly pushing the telescopic rod 7 outward.

[0033] Working principle: During use, the power cord is connected to the power plug 6. The power plug 6 and encoder 5 control the servo motor 3, causing it to rotate. Since the power output shaft of the servo motor 3 is connected to the outer wall of the drive screw 4, the servo motor 3 drives the drive screw 4 during rotation, causing the drive screw 4 to rotate within the inner cavity of the equipment housing 2. During the rotation of the drive screw 4, the screw nut 9 is driven, causing the balls in the inner cavity of the screw nut 9 to move along the threaded groove on the outer wall of the drive screw 4, thus enabling the screw nut 9 to move along the outer wall of the drive screw 4. During the movement of the screw nut 9, the guide rod 8 is driven. Since the outer wall of the guide rod 8 is connected to the outer wall of the telescopic rod 7, the telescopic rod 7 is driven, thus enabling the telescopic rod 7 to be extended.
