[0025] like Figure 1 to Figure 3 As shown, in one embodiment of the utility model, a bidirectional differential transmission linear module is involved, including a T-shaped base 1, a first transmission assembly 2, a second transmission assembly 3, a drive assembly 4 and a differential synchronization assembly 5; the two sides of the T-shaped base 1 are respectively provided with a first transmission mounting surface 11 and a second transmission mounting surface 12, the first transmission assembly 2 includes a first transmission guide rail 21, a first transmission screw rod 22 and a first transmission seat 23 arranged on the first transmission mounting surface 11, the first transmission seat 23 is installed on the first transmission guide rail 21, the first transmission screw rod 22 is connected to the first transmission seat 23, and is used to drive the first transmission seat 23 to slide along the first transmission guide rail 21; the second transmission assembly 3 includes a second transmission assembly arranged on the second transmission mounting surface 12 The guide rail 31, the second transmission screw 32 and the second transmission seat 33, the second transmission seat 33 is installed on the second transmission guide rail 31, the second transmission screw 32 is connected to the second transmission seat 33, and is used to drive the second transmission seat 33 to slide along the second transmission guide rail 31; the driving end of the driving assembly 4 is connected to the first transmission screw 22; the differential synchronization assembly 5 includes a first synchronous wheel 51, a second synchronous wheel 52 and a synchronous belt 53, one end of the first synchronous wheel 51 is connected to the first transmission screw 22, the second synchronous wheel 52 is connected to the second transmission screw 32, and the synchronous belt 53 is used to synchronously drive the first synchronous wheel 51 with the second synchronous wheel 52, and the outer diameter of the first synchronous wheel 51 is smaller than the outer diameter of the second synchronous wheel 52. In this embodiment, the module realizes the bidirectional differential transmission capability through the design of the differential synchronization assembly 5. This means that the first transmission assembly 2 and the second transmission assembly 3 can move at different speeds, so that the module can flexibly respond to different processing requirements in industrial production. The arrangement of the first transmission rail 21 and the second transmission rail 31, and the connection of the first transmission screw 22 and the second transmission screw 32, ensure that the first transmission seat 23 and the second transmission seat 33 can slide accurately along the linear track. This design improves the motion accuracy of the module and is suitable for industrial application scenarios that require high-precision linear motion.

[0026] In the above embodiment, the driving end of the driving assembly 4 is connected to the first transmission screw 22, and then the power is transmitted to the second transmission screw 32 through the differential synchronization assembly 5, thereby achieving efficient power transmission. This design improves transmission efficiency and reduces energy loss. The design of the T-shaped base 1 makes the layout of each component compact, effectively utilizes the installation space, and improves the overall integration of the equipment. This is particularly important for industrial production sites with limited space.

[0027] In the above embodiment, since the outer diameters of the first synchronous wheel 51 and the second synchronous wheel 52 are different, a suitable synchronous wheel diameter can be selected according to actual needs to meet different speed and load requirements, so that the module can flexibly adapt to various working conditions and complete different differential transmission connections, thereby improving its versatility and applicability. The synchronous transmission of the synchronous belt 53 ensures the movement synchronization of the first transmission assembly 2 and the second transmission assembly 3, thereby making the module operation more stable and reliable, reducing the possibility of failure, and improving production efficiency.

[0028] The T-shaped base 1 includes a horizontal panel 13 and a vertical panel 14, and the horizontal panel 13 and the vertical panel 14 are formed into one body by extruding aluminum alloy. Specifically, the first transmission mounting surface 11 and the second transmission mounting surface 12 are respectively arranged on both sides of the vertical panel 14. In this embodiment, the horizontal panel 13 and the vertical panel 14 are formed into one body by extruding aluminum alloy, which improves the overall structural strength and stability of the T-shaped base 1. This design ensures that the linear transmission module can withstand a large load and inertial force during operation, thereby extending its service life. Aluminum alloy has good characteristics of absorbing vibration and reducing noise, so the structural design of the T-shaped base 1 helps to reduce the vibration and noise generated by the linear transmission module during operation, and improves the stability and comfort of the equipment. The compact design of the horizontal panel 13 and the vertical panel 14 of the T-shaped base 1 effectively utilizes the installation space, so that the linear transmission module occupies a smaller space during installation, which is suitable for industrial production sites with limited space.

[0029] Both ends of the first transmission screw 22 are provided with a first screw fixing plate 221, and the first transmission screw 22 can be rotatably connected to the first screw fixing plate 221. Specifically, both ends of the second transmission screw 32 are provided with a second screw fixing plate 321, and the second transmission screw 32 can be rotatably connected to the second screw fixing plate 321. In this embodiment, the first transmission screw 22 and the second transmission screw 32 are fixed by a fixing plate and are rotatably connected. This design enhances the stability of the transmission system. The fixing plate ensures that the screw will not loosen or deviate during the movement, thereby maintaining the transmission accuracy and reliability. The setting of the screw fixing plate helps to maintain the alignment and stability of the screw, and reduces the vibration and motion error during the transmission process. This is very critical for applications that require high-precision linear motion, such as precision machining and measuring equipment. The fixed plate design makes the installation and adjustment of the screw easier. The operator can easily adjust the position of the screw or replace the screw through the fixing plate without worrying about the stability and safety of the fixation.

[0030] A motor fixing plate 15 is provided at one end of the T-shaped base 1, and the drive assembly 4 is arranged on the motor fixing plate 15 and is connected to the first transmission screw 22 by driving. Specifically, the drive assembly 4 includes a drive motor 41 and a reducer 42, and the drive motor 41 is connected to the first transmission screw 22 through the reducer 42. In this embodiment, the drive assembly 4 includes a drive motor 41 and a reducer 42, and the speed of the motor is converted into a speed suitable for the first transmission screw 22 by the reducer 42. This design can accurately control the movement speed and force output of the linear transmission module to meet the accuracy requirements of different processing requirements. The reducer 42 effectively converts the high-speed and low-torque output of the drive motor 41 into a low-speed and high-torque output suitable for screw drive. This energy transmission method improves transmission efficiency and reduces energy loss, thereby saving energy and reducing operating costs. The drive motor 41 is fixed on the motor fixing plate 15, and combined with the precise transmission of the reducer 42, the stable and reliable long-term operation of the linear transmission module is ensured. This is particularly important for scenes that require continuous and stable operation in industrial automation production.

Specifically, the cross-sectional shape of the second transmission seat 33 is an L-shape, and a second connecting table 331 is provided on one side of the second transmission seat 33, and the second connecting table 331 is provided with a second connecting hole 332. In this embodiment, the L-shaped transmission seat cross-section provides good structural strength and stability, can effectively bear the force and pressure during the transmission process, and ensure the stable operation of the transmission system. The provision of the connecting table and the connecting hole enables the transmission seat to be accurately aligned and fixed to other equipment or structures. This design is particularly suitable for application scenarios that require high-precision position control, such as automated assembly lines or precision measuring equipment.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
