Description

Technical Field

[0001] This utility model relates to the field of linear slide technology, and in particular to a lead screw linear module. Background Technology

[0002] Linear ball screw slides are commonly used transmission components in industrial automation. They are also called linear modules or electric slides and can convert the rotary motion of a motor into smooth linear motion. When linear screw slides are used, especially in dusty workshops, impurities and dirt generated during processing can easily enter the slide. These impurities can embed themselves in the gap between the screw nut and the guide rail slider, accelerating component wear, damaging the lubrication layer, causing operational jamming, reduced positioning accuracy, and in severe cases, leading to screw corrosion, motor overload, and shortening the slide's lifespan. Therefore, existing linear screw slides often use accordion-style protective covers to protect the internal components without affecting the normal operation of the linear screw slide. However, accordion-style protective covers are made of relatively soft material to achieve the telescopic function, making them prone to deformation and damage upon impact, thus losing their protective effect. Furthermore, repeated folding over a long period can lead to fatigue damage, requiring frequent replacement and increasing maintenance costs. Utility Model Content

[0003] The purpose of this invention is to provide a linear lead screw module that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A linear lead screw module includes a frame, in which a lead screw is rotatably connected. Two guide rails are symmetrically fixedly connected within the frame at positions front and rear of the lead screw. A slide table is slidably connected to the two guide rails. A bushing is fixedly connected to the lower end of the slide table and movably connected to the lead screw. A motor is fixedly connected to one side of the frame, and the output end of the motor is fixedly connected to one end of the lead screw. A protective cover is fixedly connected to the frame. Slide tracks are provided on both the front and rear sides of the protective cover. Side blocks are fixedly connected to the protective cover at positions on both sides of the slide tracks. Two rubber pads are fixedly connected to the front and rear sides of the protective cover near the slide tracks. Carrier plates are fixedly connected to the front and rear sides of the slide table and extend to the top of the protective cover.

[0005] As a further optimization of this utility model, the longitudinal cross-section of the two rubber pads is triangular, and the parts of the two rubber pads away from the connecting block will automatically close, so as to prevent external impurities and dirt from entering the frame.

[0006] As a further optimization of this utility model, the carrier plate has an L-shaped structure, and a connecting block is fixedly connected to one side of the carrier plate. The connecting block passes through one of the slide rails and is fixedly connected to the front or rear side of the slide table, thereby completing the assembly of the carrier plate and the slide table, and allowing the connecting block to slide within the slide rail via the slide table.

[0007] As a further optimization of this utility model, the connecting block is provided with a double-slope structure on both sides, so that when the connecting block separates the two rubber pads, the two rubber pads can fit together with the contact surfaces on both sides of the connecting block, reducing the gaps of the rubber pads on both sides of the connecting block and improving the protective effect.

[0008] As a further optimization of this utility model, a number of ball grooves are provided in the carrier plate located below the connecting block. A ball cap is threaded to one side of the ball groove, and a ball is rotatably connected in the ball groove. After the carrier plate is installed on the slide table through the connecting block, it will be located in the front or rear position of the protective cover, and the ball will slide against the front or rear position of the protective cover, thereby improving the stability of the carrier plate operation and the weighing capacity.

[0009] As a further optimization of this utility model, mounting bases are fixedly connected to the two carrier plates to enable the installation of external devices.

[0010] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the rigid protective cover avoids the problem of fatigue damage caused by traditional bellows-style protective covers, reducing maintenance and replacement costs. The triangular rubber pads on the cover can automatically close the slide, and the double-slope design of the connecting block further reduces gaps, effectively blocking impurities from entering and protecting core components such as lead screws and guide rails. This reduces wear, maintains lubrication, avoids operational jamming and decreased positioning accuracy, and extends the service life of the equipment. Attached Figure Description

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figures 1-5 As shown, the present invention provides a lead screw linear module, including a frame 1, a lead screw 2 rotatably connected inside the frame 1, two guide rails 3 symmetrically fixedly connected inside the frame 1 at the front and rear sides of the lead screw 2, a slide table 4 slidably connected on the two guide rails 3, a bushing 5 fixedly connected to the lower end of the slide table 4 and movably connected to the lead screw 2, a motor 6 fixedly connected to one side of the frame 1, the output end of the motor 6 fixedly connected to one end of the lead screw 2, a protective cover 7 fixedly connected to the frame 1, slide rails 8 opened on the front and rear sides of the protective cover 7, side blocks 9 fixedly connected to the protective cover 7 at the two sides of the slide rails 8, two rubber pads 10 fixedly connected to the front and rear sides of the protective cover 7 near the slide rails 8, and a carrier plate 11 fixedly connected to the front and rear sides of the slide table 4 and extending to the position above the protective cover 7.

[0015] like Figures 1-4 As shown, the longitudinal cross-section of the two rubber pads 10 is triangular, and the parts of the two rubber pads 10 away from the connecting block 12 will automatically close, so as to prevent external impurities and dirt from entering the frame 1.

[0016] like Figures 2-5 As shown, the carrier plate 11 has an L-shaped structure. A connecting block 12 is fixedly connected to one side of the carrier plate 11. The connecting block 12 passes through one of the slide rails 8 and is fixedly connected to the front or rear side of the slide table 4, thereby completing the assembly of the carrier plate 11 and the slide table 4. The connecting block 12 also slides within the slide rail 8 via the slide table 4. Both sides of the connecting block 12 are provided with a double-slope structure to ensure that when the two rubber pads 10 are separated, the contact surfaces of the two rubber pads 10 and the two sides of the connecting block 12 can fit together, reducing the position of the rubber pads 10 on both sides of the connecting block 12. The perforations enhance the protective effect. Several ball grooves 14 are provided in the carrier plate 11 located below the connecting block 12. A ball cap 15 is threaded to one side of the ball groove 14. A ball ball 16 is also rotatably connected in the ball groove 14. After the carrier plate 11 is installed on the slide table 4 through the connecting block 12, it will be located in the front or rear position of the protective cover 7. The ball ball 16 will slide against the front or rear position of the protective cover 7, thereby improving the stability of the carrier plate 11 and its load-bearing capacity. Mounting bases 13 are fixedly connected to the two carrier plates 11 to realize the installation of external equipment.

[0017] It should be noted that this utility model is a lead screw linear module. After the motor 6 is started, the output end of the motor 6 drives the lead screw 2 to rotate in the frame 1. The bushing 5, which is movably connected to the lead screw 2, generates axial displacement as the lead screw 2 rotates, thereby driving the slide table 4 to make a smooth linear motion along the two symmetrically arranged guide rails 3. When the slide 4 moves, the front and rear carrier plates 11 move synchronously through the connecting block 12. The connecting block 12 slides through the slide rail 8 of the protective cover 7. Therefore, the protective cover 7 provides protection for the core components such as the lead screw 2 and guide rail 3 inside the frame 1. The two triangular rubber pads 10 on the protective cover 7 are automatically closed under normal conditions to prevent dust and impurities from entering. When the connecting block 12 moves, its double-slope structure will smoothly separate the rubber pads 10 and fit tightly with the rubber pads 10 to reduce gaps and maintain the protective effect. When the carrier plate 11 moves, the balls 16 in the ball groove 14 below the carrier plate 11 slide against the surface of the protective cover 7, reducing the friction when the carrier plate 11 moves and improving the running stability and load-bearing capacity.
