Description

Technical Field

[0001] This utility model relates to the field of linear module technology, and in particular to a linear module with good load-bearing performance. Background Technology

[0002] A linear module is a mechanical transmission device that can realize linear reciprocating motion. It is also commonly known as a linear module or electric slide table. As a transmission device that realizes linear reciprocating motion, it has a wide range of applications in many fields such as automated production, machining, and electronic equipment.

[0003] Currently, the support platform on existing linear modules, as a key load-bearing component, is prone to wear and deformation after long-term use, which affects the overall performance of the linear module. Furthermore, since the connection between the support platform and other parts of most linear modules is complex, maintenance of the support platform often requires the disassembly of a large number of parts, resulting in a large workload and cost. At the same time, the nut seat needs to bear a large load during the operation of the linear module, and it is prone to displacement during movement, which affects the motion accuracy and stability. Therefore, to solve these problems, designing a linear module with good load-bearing performance is something we need to consider. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a linear module with good load-bearing capacity. In terms of usage, it is equipped with a limiting component, which enables maintenance and replacement of the support platform. Replacement only requires manipulating two bolts, reducing maintenance workload and costs. It is also equipped with a sliding groove and pulley to guide and support the movement of the nut seat, which greatly improves the load-bearing capacity of the linear module and makes it highly practical.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A linear module with good load-bearing capacity includes a base with a movable groove at its upper end; a movable component including a motor mounted on the front side of the base, a ball screw rotatably connected between the inner walls of the front and rear sides of the movable groove, and a matching nut seat fitted on the outer wall of the ball screw; and a limiting component including a convex inner groove on the front side of the nut seat, a convex connecting block fitted in the convex inner groove, a support platform fixedly connected to the upper end of the convex connecting block, threaded grooves on both the left and right sides of the convex connecting block, and bolts on both the left and right sides of the nut seat.

[0007] Preferably, the front end of the ball screw passes through the front inner wall of the moving groove and is fixedly connected to the output shaft of the motor.

[0008] Preferably, the shank portions of both bolts penetrate the sidewall of the nut seat and are threadedly connected to the corresponding thread groove.

[0009] Preferably, rectangular inner grooves are provided on the inner walls of both the left and right sides of the moving groove, and sliding grooves are provided on the inner top and inner bottom of the two rectangular inner grooves.

[0010] Preferably, a fixing block is fixedly connected to both the left and right sides of the nut seat, and multiple pulleys are installed at the upper and lower ends of the two fixing blocks.

[0011] Preferably, each pulley is fitted with a corresponding groove.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] This utility model is equipped with a moving component and a limiting component. By starting the motor, the nut seat and the support platform move together, which can accurately drive the product on the support platform to perform linear motion, meeting the requirements of high-precision operation. At the same time, only two bolts on the left and right sides of the nut seat need to be removed to disconnect the connection between the convex connecting block and the nut seat, which greatly optimizes the maintenance process and efficiency of the linear module and significantly reduces the maintenance workload and maintenance cost.

[0014] In addition, the rolling of multiple pulleys in corresponding grooves not only provides precise guidance for the movement of the nut seat, ensuring that the entire linear module maintains high stability during operation, but also reasonably distributes the load borne by the nut seat, greatly enhancing the load-bearing capacity of the entire linear module, resulting in good overall practicality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0022] Reference Figures 1-2 A linear module with good load-bearing capacity includes a base 1, and a movable groove 2 is provided at the upper end of the base 1.

[0023] The system also includes a moving component, which includes a motor 3 mounted on the front side of the base 1. The motor 3 is a motor that can change the direction of rotation. A ball screw 4 is rotatably connected between the inner walls of the front and rear sides of the moving groove 2. The front end of the ball screw 4 passes through the inner wall of the front side of the moving groove 2 (a bearing is provided at the penetration point) and is fixedly connected to the output shaft of the motor 3. A matching nut seat 5 is sleeved on the outer wall of the ball screw 4. This is the prior art. Multiple balls are provided in the nut seat 5. As rolling elements, they roll between the ball screw 4 and the nut seat 5, thereby reducing friction and improving the actual transmission efficiency.

[0024] The system also includes a limiting component, which includes a convex inner groove 6 on the front side of the nut seat 5. A convex connecting block 7 is fitted inside the convex inner groove 6 and is slidably connected to the inner wall of the convex inner groove 6. A support platform 8 is fixedly connected to the upper end of the convex connecting block 7. Threaded grooves 9 are provided on both the left and right sides of the convex connecting block 7. Bolts 10 are provided on both the left and right sides of the nut seat 5. The threaded part of the two bolts 10 penetrates the side wall of the nut seat 5 and is threadedly connected to the corresponding threaded groove 9. By using a tool to remove the two bolts 10, the convex connecting block 7 and the support platform 8 can be pulled out for maintenance and replacement.

[0025] In this utility model, when in use, the starting motor 3 drives the ball screw 4 to rotate, which can drive the nut seat 5 and the support platform 8 to move back and forth synchronously, thereby realizing the precise linear motion of the product on the support platform 8.

[0026] When maintenance or replacement of the support platform 8 is required, the operator can use tools to remove the bolts 10 on both sides of the nut seat 5 in sequence. Since the threaded part of the bolt 10 penetrates the side wall of the nut seat 5 and is threadedly connected to the threaded grooves 9 on both sides of the convex connecting block 7, after removing the two bolts 10, the connection between the convex connecting block 7 and the nut seat 5 will be released. At this time, the convex connecting block 7 and the support platform 8 can be pulled forward for maintenance and replacement. After maintenance and replacement are completed, the convex connecting block 7 is reinserted into the convex inner groove 6. Finally, the two bolts 10 are used to fix the convex connecting block 7 and the nut seat 5. The entire loading, unloading and maintenance process can be completed by manipulating only two bolts 10. Compared with the traditional integrated structure or multi-bolt connection structure, this improves the maintenance workload and efficiency of the linear module and reduces maintenance costs. Example

[0027] Reference Figures 3-5 The difference between this embodiment and embodiment 1 is that, in this embodiment, rectangular inner grooves 11 are provided on the inner walls of both the left and right sides of the moving groove 2, and sliding grooves 12 are provided on the inner top and inner bottom of the two rectangular inner grooves 11. Fixing blocks 13 are fixedly connected to both the left and right sides of the nut seat 5, and multiple pulleys 14 are installed at the upper and lower ends of the two fixing blocks 13. Each pulley 14 cooperates with the corresponding sliding groove 12. When the nut seat 5 moves, the multiple pulleys 14 will move synchronously with the nut seat 5 in the corresponding sliding groove 12, thereby playing a guiding role and improving the load performance.

[0028] In this invention, when the nut seat 5 moves, multiple pulleys 14 move synchronously with the nut seat 5 in the corresponding grooves 12. The pulleys 14 roll along the grooves 12 to guide the nut seat 5, ensuring that the nut seat 5 moves stably in a predetermined direction. At the same time, the pulleys 14 can provide some support for the nut seat 5 during the movement, sharing part of the load borne by the nut seat 5, thereby improving the load-bearing performance of the entire linear module.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
