DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example
[0019] See also Figure 1-4 The utility model provides a technical solution: an integrated screw steel module structure, including a base 100 made of high carbon steel, one end of the base 100 is fixedly installed with a rear end plate 120 by a first fixing screw 110, and the other end of the base 100 is fixedly installed with a motor base 140 by a second fixing screw 130. One end of the motor base 140 is installed with a bearing 170 through a bearing cover 150 and a locking nut 160. A rolling screw 200 is installed between the bearing 170 and the rear end plate 120, and an external sliding sleeve of the rolling screw 200 is provided with a slide 300. Both the slide 300 and the base 100 are provided with a raceway 400. The interior of the slide 300 is connected to the rolling screw 200 in a rolling manner by a steel ball return mechanism 310 provided therein in cooperation with a plurality of steel balls. The slide 300 is also connected in a sliding manner to the raceway 400 through a steel ball reflux mechanism 320 provided therein.
[0020] Specifically, the base 100 can be integrally formed of steel material, and the base 100 is used as the cornerstone of the entire module structure. The rear end plate 120 and the motor base 140 can be fixedly mounted on both ends of the base 100 by first fixing screws 110 and second fixing screws 130, respectively, to form the basic framework of the module.
[0021] The bearing 170 is installed at one end of the motor base 140 through the cooperation of the bearing cover 150 and the locking nut 160, and then the rolling screw 200 is installed between the bearing 170 and the rear end plate 120 to form a rotatable shaft system. When the motor drives the rolling screw 200 to rotate, the slide 300 sleeved on its outside starts to move, and the slide 300 and the raceway 400 on the base 100 cooperate with the steel ball to provide a guide for the linear motion of the slide 300. Compared with the screw and the screw in the transmission screw module, the The matching method of the nut and the set steel ball return mechanism 310 can make the screw steel module structure more compact and realize structural integration; and the steel ball return mechanism 310 and the steel ball reflux mechanism 320 inside the slide 300 work together to ensure that the rolling connection between the slide 300 and the rolling screw 200 is stable and reliable, thereby efficiently converting the rotational motion of the rolling screw 200 into the precise linear motion of the slide 300 along the base 100, realizing effective power transmission and precise displacement conversion.
[0022] In the present invention, the steel ball return mechanism 310 includes a spiral steel ball groove 311 provided inside the slide 300 , and a first nut steel ball return device 312 and a second nut steel ball return device 313 are respectively installed at both ends of the spiral steel ball groove 311 .
[0023] Specifically, the steel ball return mechanism 310 can replace the screw nut of the traditional screw module, wherein the spiral steel ball groove 311 can provide a storage and running channel for the steel ball, and at the same time provide space for the rolling of the steel ball. During the rotation of the rolling screw 200, the steel ball rolls in the spiral steel ball groove 311. When the steel ball rolls to the end of the spiral steel ball groove 311, the first nut steel ball returner 312 or the second nut steel ball returner 313 plays a role, which can flexibly change the rolling direction of the steel ball, so that the steel ball can continue to circulate and roll in the spiral steel ball groove 311, ensuring a stable rolling connection between the slide 300 and the rolling screw 200, and at the same time enabling the rotational motion of the rolling screw 200 to be accurately converted into the linear motion of the slide 300, ensuring the accuracy and stability of the module during operation.
[0024] In this embodiment: the steel ball reflux mechanism 320 includes a first steel ball reflux groove 321 and a second steel ball reflux groove 322 respectively located at both ends of the slide 300 by screws, and a steel ball return device 323 is installed between the first steel ball reflux groove 321 and the second steel ball reflux groove 322 and the slide 300. The steel ball return device 323 is connected to the steel ball flow channel 324 provided inside the slide 300, and the steel ball return device 323 is also connected to the raceway 400.
[0025] Specifically, when the slide 300 slides with the base 100, the slide 300 can slide along the raceway 400, and the steel balls circulate between the steel ball return groove, the steel ball flow channel 324 and the raceway 400. During the circulation process, the steel balls continuously provide support for the slide 300 and effectively reduce the friction between the slide 300 and the raceway 400, ensuring the smoothness and accuracy of the movement of the slide 300, making the operation of the module in the automated equipment more reliable and meeting the high-precision movement requirements.
[0026] In this embodiment, two scrapers 325 are provided at one end of the second steel ball return channel 322 , and the two scrapers 325 are also fixedly connected to the slide seat 300 by screws.
[0027] Specifically, during the operation of the module, when the slide 300 slides on the raceway 400, impurities or dust are prevented from entering the steel ball return groove. The scraper 325 can scrape off impurities that may enter the steel ball return groove to prevent impurities from interfering with the normal rolling and circulation of the steel balls.
[0028] In this embodiment, a mounting position for a stepper motor or a servo motor is reserved inside the motor base 140 , and one end of the rolling screw 200 is transmission-connected to the output shaft of the stepper motor or the servo motor via an encoder.
[0029] Specifically, the set mounting position can be used to install a stepper motor or a servo motor. When the motor starts to rotate, the encoder can accurately measure the speed, rotation angle, and rotation direction of the motor output shaft. The precise measurement information can be fed back to the control system in real time. Based on this feedback information, the control system uses advanced algorithms to accurately control the rotation of the motor to ensure the operating accuracy of the module.
[0030] In this embodiment, a grating scale or a magnetic scale is installed on the outer side of the base 100 .
[0031] Specifically, when the slide 300 makes a linear motion on the raceway 400 of the base 100, the grating scale or magnetic scale will generate a corresponding signal according to the displacement of the slide 300, and then feed it back to the control system. The control system is used to control the motor movement, ensuring the high-precision operation of the entire module in the automation equipment.
