As the adjusting bearing moves, the distance between the two groups of adjusting bearings on both sides of the linear guide can be flexibly adjusted.

This adjustability enables the linear module to flexibly respond to different transportation scenarios, whether it is a small load or a large load, to ensure stable operation of the load, thereby improving the versatility of the linear module; and the mounting holes on the connecting block and the expansion block provide a convenient and firm connection for the installation of the load device, further improving the stability of the linear module.

[0017] 3. Through the setting of the adjustment component, when the linear module is used, by starting the second electric telescopic rod, the contact state between the two groups of first adjustment plates and the toothed belt can be switched, so that the toothed clamps on one group of first adjustment plates contact the toothed belt, and the toothed belt is clamped between the friction block and one group of first adjustment plates, so that the two groups of sliders can switch between the same direction movement or relative movement; this flexible movement mode switching function enables the linear module to be suitable for different working occasions. In some production lines that require synchronous movement, the same direction movement mode can be selected; and in situations where the load needs to be stretched or compressed, it can be switched to the relative movement mode, which solves the problem of lack of flexibility of traditional linear modules. This dual-drive function not only improves the scope of application of the linear module, but also provides a more flexible solution for the production needs of users, thereby improving the flexibility of the linear module.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but cannot be used to limit the scope of protection of the present invention.

[0021] Embodiment 1: As shown in the attached Figures 1 to 13 As shown: The present invention provides an adjustable dual-drive linear module, including a slide 101, two groups of slidable sliders 102 are arranged on the top of the slide 101, a linear guide 103 is arranged inside the slide 101, and the bottoms of the two groups of sliders 102 are provided with sliding components that are slidably connected to the linear guide 103. The sliding components include two groups of adjustment bearings 201, and the bottoms of the sliders 102 are respectively provided with two groups of adjustment bearings 201 connected to the linear guide 103. This dual-slider structure not only improves the stability of the whole machine, but also realizes the dynamic adjustment of the hugging force of the linear guide 103 by adjusting the contact pressure of the two groups of adjustment bearings 201, which can effectively avoid the load change. and the precision deviation caused by it; at the same time, two groups of first gears 104 and a group of toothed belts 105 are also provided inside the slide 101, and the two ends of the toothed belts 105 are respectively mounted on the two groups of first gears 104, and a driving motor 106 is provided at the bottom of the slide 101.

The two groups of sliders 102 are connected to the toothed belts 105 through adjustment components; in addition, expansion components are provided on the two groups of sliders 102.

[0022] Please refer to Figure 3 and Figure 4 As shown, in addition to two groups of adjustable adjusting bearings 201, the sliding assembly also includes four groups of fixed bearings 202. Fixed bearings 202 are arranged on both sides of the two groups of adjusting bearings 201. Four groups of fixing columns 203 are arranged at the bottom of the slider 102 corresponding to the four groups of fixed bearings 202. The four groups of fixing columns 203 are connected with screws to firmly fix the four groups of fixed bearings 202 at the bottom of the slider 102. At the same time, guide shafts 204 are arranged on both sides of the linear guide 103. The grooves of the four groups of fixed bearings 202 and the grooves on the two groups of adjusting bearings 201 are respectively engaged with the two groups of guide shafts 204. This multi-bearing support structure improves the rigidity and stability of the linear module, and further ensures the stability and positioning accuracy of the slider 102 running on the linear guide 103 through the setting of the guide shaft 204. At the same time, due to the adjustability of the adjusting bearing 201, the user can flexibly adjust the contact pressure of the slider 102 according to different load requirements, thereby improving reliability.

[0023] Please refer to Figure 4 and Figure 5 As shown, a first mounting groove 205 is provided at the bottom of the slider 102, and two sets of slidable sliding rails 206 are arranged inside the first mounting groove 205. The two sets of sliding rails 206 are installed in the first mounting groove 205, providing a stable sliding basis for subsequent components; each set of sliding rails 206 is equipped with a set of slidable racks 207, through which the racks 207 can slide smoothly on the sliding rails 206; at the same time, a rotatable second gear 208 is also provided inside the first mounting groove 205, and the second gear 208 forms a meshing fit with the two sets of racks 207. When the second gear 208 rotates, the transmission between the second gear 208 and the two sets of racks 207 can drive the two sets of racks 207 to slide left and right along the sliding rails 206; the second gear 208 is rotated by an external control device to adjust the position of the rack 207, which further affects the state of other components connected to the rack 207, thereby adjusting the operating parameters of the linear module.

[0024] Please refer to Figure 4 and Figure 5As shown, a fixing cylinder 209 is provided at one end of the two sets of racks 207. The two sets of adjusting bearings 201 are tightly connected to the bottom ends of the two sets of fixing cylinders 209 by means of a reliable connection method of two sets of screws.

In this groove, a first electric telescopic rod 210 is installed. One end of the first electric telescopic rod 210 is connected to one of the sets of racks 207. When the first electric telescopic rod 210 is started, a driving force is generated. This driving force can push the corresponding rack 207 to move left and right along the sliding track 206. With the movement of the rack 207, since the rack 207 and the adjusting bearing 201 are tightly connected by the fixing cylinder 209 and the screws, the distance between the two sets of adjusting bearings 201 is adjusted accordingly. By controlling the connection between the two sets of adjusting bearings 201 and the linear guide 103 The contact pressure can effectively solve the sliding or offset problems that are prone to occur in traditional linear modules when the load changes. In traditional linear modules, when the load changes, it is often difficult to maintain a stable operating state, and instability is prone to occur, affecting work efficiency and accuracy.

Whether it is light load or heavy load, it can maintain stable operation, thereby improving the reliability and adaptability of the linear module. In addition, this structure can also enable the linear module to adapt to different working environments. By adjusting the contact pressure between the adjusting bearing 201 and the linear guide 103, the linear module can maintain stable performance in different working environments, ensuring the stability of the linear module under load, and providing reliable support for various complex work tasks.
