Description

Technical Field

[0002] A linear module is a linear transmission device that comes in two main forms. One consists of a ball screw and linear guide, and the other uses a synchronous belt and pulley. In the automation industry, it is a general term for devices that can achieve linear motion. Also known as positioning modules, linear modules can be considered a widely used intellectual product that mechanical engineers have developed through sharing experiences and knowledge through mechanical modification and development.

[0004] Although the linear module of the above patent has high precision, it uses a lead screw to control movement. Once the module stroke is long, a longer lead screw is required. However, the lead screw may not be strong enough for long-distance, heavy-load linear operation, resulting in vibration and jitter. In severe cases, the lead screw may bend, deform, or even break, thereby damaging the module. Therefore, it is necessary to design an efficient and precise linear module to solve the above problems.

[0027] During specific use, through the arrangement of guide rails 2, sliders 3, slides 4, motors 7, gears 9 and racks 10, the two sets of guide rails 2 and racks 10 are fixed to the upper surface of the base plate 1 by the first bolt and the fourth bolt respectively, which is easy to install and convenient to replace and maintain when damaged, saving costs. At the same time, the module can extend the guide rails 2 and racks 10 as needed, increasing the practicality of the module. The sliders 3 are slidably connected to the outer surface of the guide rails 2 to support and guide the slides 4 to prevent the slides 4 from offsetting when moving. The planetary reducer 6 is fixed to the upper surface of the slide 4 by the connecting plate 5 and the third bolt. Under the action of the motor 7 and the planetary reducer 6, the rotating rod 8 can be controlled to rotate, so that the gear 9 can move linearly on the outer surface of the rack 10. Since the rack 10 and the guide rails 2 can be spliced, the vibration and jitter caused by the insufficient strength of the lead screw linear module can be solved to the greatest extent. At the same time, the module has a stronger load-bearing capacity, more stable movement, and unrestricted movement distance, which expands the scope of use of the module.

[0028] In this embodiment, a sliding groove 11 is provided in the middle of the inner side surface of the guide rail 2 , and a rubber wheel 12 is slidably connected inside the sliding groove 11 . The rubber wheel 12 is rotatably connected to the slider 3 .

[0029] During specific use, through the setting of the slide groove 11 and the rubber wheel 12, when the slider 3 moves, the rubber wheel 12 on its inner side slides inside the slide groove 11, which can reduce the friction resistance encountered by the slider 3 during sliding, improve the working efficiency of the transmission, and the rubber wheel 12 can reduce the noise emitted by the slider 3, ensure the smoothness of the slider 3 during movement, and facilitate use by the staff.

[0031] During specific use, by setting the guide rails 2, the two groups of guide rails 2 are set relative to each other, so as to limit and guide the slider 3, prevent the slider 3 from shaking left and right when moving, and increase the stability of the movement.

[0032] In this embodiment, a connection block 13 is fixedly connected to one side of the upper surface of the slide 4 , and a connection hole 14 is formed on the upper surface of the connection block 13 .

[0033] During specific use, the connection block 13 and the connection hole 14 are arranged to cooperate with each other, so as to facilitate the connection between the module and external components and play a connecting role.

[0034] In this embodiment, a baffle 15 is fixedly connected to the edge of the upper surface of the bottom plate 1 .

[0035] During specific use, the baffle 15 is set and fixed at the edge of the upper surface of the base plate 1. Its inner side and the guide rail 2 form a placement area for placing the drag chain, ensuring the safety of the module when in use and avoiding clutter on the module surface.

[0037] During specific use, through the setting of the side panel 16, the side panel 16 is fixed to the two ends of the base plate 1 and the guide rail 2 by multiple fifth bolts, connecting and fixing the two while limiting the slide 4 to prevent it from detaching from the module. The trapezoidal plate 17 plays the role of supporting the buffer plate 18.

[0038] In this embodiment, a buffer plate 18 is fixedly connected to the inner side of the trapezoidal plate 17 , a rubber pad 19 is fixedly connected to the outer surface of the trapezoidal plate 17 , and a silicone pad 20 is fixedly connected to the outer surface of the slide 4 .

[0039] During specific use, through the setting of the buffer plate 18, before the slide 4 and the trapezoidal plate 17 contact each other, the silicone pad 20 and the rubber pad 19 first contact each other, and then under the action of force, the trapezoidal plate 17 is squeezed, and the buffer plate 18 buffers and unloads the generated force. The buffer plate 18 is deformed under force to limit and block the slide 4, thereby improving the reliability of the module and the safety of use.

[0042] Working principle: In use, first fix the four groups of sliders 3 to the lower surface of the slide 4, fix the planetary reducer 6 to the upper surface of the slide 4 through the connecting plate 5, adjust the spacing between the two guide rails 2 and the installation position of the rack 10 according to the position of the slider 3 and the gear 9, first install the side plate 16 at one end, then slide the slider 3 to connect it to the outer surface of the guide rail 2, and then install the side plate 16 on the other side. The four groups of mounting holes 22 are used in conjunction with the screws to fix the mounting plate 21, and install the module at the designated location. Under the action of the motor 7 and the planetary reducer 6, the rotating rod 8 is controlled to rotate so that the gear 9 meshes linearly with the outer surface of the rack 10. The rack 10 and the guide rail 2 can be spliced ​​together to solve the vibration and jitter caused by the insufficient strength of the screw linear module to the greatest extent. When the slider 3 moves, the rubber wheel 12 slides inside the slide groove 11, which can reduce the friction resistance of the slider 3 when sliding and improve the working efficiency of the transmission. Before the slide 4 and the trapezoidal plate 17 contact each other, the silicone pad 20 and the rubber pad 19 first contact each other, and then under the action of force, the trapezoidal plate 17 is squeezed, and the buffer plate 18 buffers and unloads the force generated. The buffer plate 18 is deformed under force to limit and block the slide 4, thereby improving the reliability of the module and the safety of use.
