Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a lightweight linear module with built-in reinforcing ribs. Background Technology

[0002] The lightweight linear module is a high-efficiency transmission unit that integrates precision mechanical design and materials science. Its core lies in achieving a balance between strength and weight through a built-in reinforcing rib structure. While reducing the overall weight by using aluminum alloy materials, the mechanical optimization design of the reinforcing ribs enhances the resistance to deformation, ensuring stability and positioning accuracy during high-speed movement. As a key component in the field of automation, it can achieve precise linear or composite trajectory movement of the load through motor drive. It is widely applicable to 3C electronic assembly, medical device delivery, and precision testing equipment scenarios. It not only meets the modern industrial demand for lightweight and energy-saving equipment, but also supports the efficient operation of high-precision production processes with its micron-level positioning capability.

[0003] Existing lightweight linear modules fix the reinforcing ribs by welding them to the bottom of the module. However, the high temperature during welding can cause localized heating of the module, leading to thermal deformation, stress concentration, and even changes in the metallographic structure of the material, reducing the strength or toughness of the substrate. This is especially true for linear modules with high precision requirements, where deformation can directly affect transmission accuracy. Current technology uses screws to fix the reinforcing ribs, but vibrations during linear module operation can cause the screws to gradually loosen, reducing connection strength and even causing the reinforcing ribs to shift, affecting module rigidity and transmission accuracy. Summary of the Invention

[0004] To overcome the above deficiencies, this utility model provides a lightweight linear module with built-in reinforcing ribs, aiming to improve the problem in the prior art where vibration during operation of linear modules causes screws to gradually loosen, reducing connection strength and even causing the reinforcing ribs to shift, affecting module rigidity and transmission accuracy.

[0006] As a further description of the above technical solution:

[0007] The drive assembly includes a hexagonal nut mounted on the outside of a bolt. A worm gear is fixedly connected to the outer wall of the hexagonal nut. Multiple worm wheels are mounted on the bottom outer side of the worm gear. The bottom of the outer wall of the worm gear meshes with the top of the outer wall of the worm wheel. A lead screw is fixedly connected to the middle of the worm wheel. The front and rear ends of the outer walls of the multiple lead screws are rotatably connected to the inner wall of the machine body. The outer wall of the lead screw is threadedly connected to the inner wall of the fixed arc plate.

[0008] As a further description of the above technical solution:

[0009] The clamping mechanism includes a first clamping frame, which is mounted on the top of the machine body. A first linkage gear is mounted on the bottom of the outer wall of the first clamping frame, and the bottom of the outer wall of the first clamping frame meshes with the top of the outer wall of the first linkage gear. A second linkage gear is mounted on the left side of the outer wall of the first linkage gear, and the left side of the outer wall of the first linkage gear meshes with the right side of the outer wall of the second linkage gear. A second clamping frame is mounted on the top of the outer wall of the second linkage gear, and the top of the outer wall of the second linkage gear meshes with the bottom of the outer wall of the second clamping frame. A support shaft is rotatably connected to the middle of the second linkage gear, and a power component is mounted on the front end of the first linkage gear.

[0010] As a further description of the above technical solution:

[0011] The power assembly includes a triangular knob, which is mounted on the front end of the first linkage gear. A rotating shaft is fixedly connected to the rear side of the outer wall of the triangular knob. A ratchet is fixedly connected to the outer wall of the rotating shaft. A pawl bracket is mounted on the top outer side of the ratchet. A support is slidably connected to the bottom end of the first clamping frame. The rear end of the outer wall of the support is slidably connected to the bottom end of the second clamping frame.

[0012] As a further description of the above technical solution:

[0013] The bottom of the machine body is equipped with a rib, and the outer walls of the rib are fixedly connected to the left and right sides with fixing blocks.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the machine body is fixedly connected to the left and right sides with protective frames, and the top of each of the protective frames adopts a rectangular design.

Through the meshing of the worm gear and the worm wheel, the two worm wheels drive the lead screw welded in the middle to rotate synchronously on the inner wall of the machine body. The lead screw is connected to the fixed arc plate through a thread. Due to the rotation restriction of the two lead screws, the fixed arc plate can only slide inside the machine body along its axial diameter when the lead screw rotates. When the bolt passes through the fixing block and is inserted into the machine body, the reinforcing rib is fixed to the bottom of the machine body by the engagement of the fixed arc plate with the bolt groove.

[0022] 2. In this utility model, rotating the triangular knob causes the rotating shaft on the rear side of its outer wall to rotate, which in turn drives the ratchet welded to the outer wall to rotate. The rotating shaft drives the first linkage gear to rotate. Through the meshing of the first linkage gear and the second linkage gear, the second linkage gear rotates on the support shaft. The first linkage gear drives the first clamping frame to move, and the second linkage gear drives the second clamping frame to move. The rotation of the rotating shaft causes the two clamping frames to move relative to each other, thereby achieving the clamping of the parts transported on the top of the moving block.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 3 and Figure 4 This utility model provides an embodiment of a lightweight linear module with built-in reinforcing ribs, comprising a body 1, with fixing mechanisms 2 installed at both the left and right ends of the body 1, and multiple fixing mechanisms 2 used to fix the reinforcing ribs; a clamping mechanism 3 is installed on the top of the body 1 for clamping components; each fixing mechanism 2 includes multiple bolts 201, which are respectively installed at the left and right ends of the body 1; a fixing arc plate 202 is installed on the rear side of the outer wall of the bolt 201; and a driving assembly 203 is installed on the outer side of the bolt 201. 03 includes a hexagonal nut 2031, which is installed on the outside of the bolt 201. A worm 2032 is fixedly connected to the outer wall of the hexagonal nut 2031. Multiple worm wheels 2033 are installed on the bottom of the outer side of the worm 2032. The bottom of the outer wall of the worm 2032 meshes with the top of the outer wall of the worm wheel 2033. A lead screw 2034 is fixedly connected to the middle of the worm wheel 2033. The front and rear ends of the outer walls of the multiple lead screws 2034 are rotatably connected to the inner wall of the machine body 1. The outer wall of the lead screw 2034 is threadedly connected to the inner wall of the fixed arc plate 202.

[0033] Specifically, rotating the hexagonal nut 2031 drives the worm gear 2032 on the outer wall to rotate, converting the operating force into rotational power. Through the meshing of the worm gear 2032 and the worm wheel 2033, the power is transmitted and its direction is changed, causing the two worm wheels 2033 to drive the lead screw 2034 in the middle to rotate synchronously on the inner wall of the machine body 1, ensuring the consistency of movement on both sides. The lead screw 2034 is internally connected to the fixed arc plate 202 through a thread, converting the rotational motion into linear motion. Due to the rotational limitation of the two lead screws 2034... When the lead screw 2034 rotates, the fixed arc plate 202 can only slide inside the body 1 along the axial diameter of the lead screw 2034, ensuring a stable movement trajectory. When the bolt 201 is inserted into the body 1 through the fixed block 5, the fixed arc plate 202 and the groove of the bolt 201 fit together to form a mechanical lock. Combined with the self-locking characteristics of the worm gear 2032 and the worm wheel 2033, reverse movement is prevented, thus fixing the reinforcing rib to the bottom of the body 1. The body 1 is made of alloy material, and through the cooperation with the reinforcing rib, the module can be lightweight while having high rigidity.

[0034] Reference Figure 1 , Figure 5 and Figure 6 The clamping mechanism 3 includes a first clamping frame 301, which is mounted on the top of the machine body 1. A first linkage gear 303 is mounted on the bottom of the outer wall of the first clamping frame 301, and the bottom of the outer wall of the first clamping frame 301 meshes with the top of the outer wall of the first linkage gear 303. A second linkage gear 304 is mounted on the left side of the outer wall of the first linkage gear 303, and the left side of the outer wall of the first linkage gear 303 meshes with the right side of the outer wall of the second linkage gear 304. A second clamping frame 302 is mounted on the top of the outer wall of the second linkage gear 304, and the top of the outer wall of the second linkage gear 304 meshes with the bottom of the outer wall of the second clamping frame 302. The second linkage gear 304 is rotatably connected to the middle of the support shaft 305. The front end of the first linkage gear 303 is equipped with a power assembly 306. The power assembly 306 includes a triangular knob 3061. The triangular knob 3061 is installed at the front end of the first linkage gear 303. The rear side of the outer wall of the triangular knob 3061 is fixedly connected to the rotating shaft 3062. The outer wall of the rotating shaft 3062 is fixedly connected to the ratchet 3063. The top of the outer side of the ratchet 3063 is equipped with a pawl bracket 3064. The bottom end of the first clamping frame 301 is slidably connected to the bracket 3065. The rear end of the outer wall of the bracket 3065 is slidably connected to the bottom end of the second clamping frame 302.

[0035] Specifically, rotating the triangular knob 3061 causes the shaft 3062 on the rear side of its outer wall to rotate, providing power for the clamping action. This, in turn, drives the ratchet 3063 on the outer wall to rotate. Simultaneously, the shaft 3062 drives the first linkage gear 303 to rotate. Through the meshing of the first linkage gear 303 and the second linkage gear 304, power is transmitted to the second linkage gear 304, causing the second linkage gear 304 to rotate on the support shaft 305. The support shaft 305 provides stable support for the second linkage gear 304, ensuring smooth rotation. Because the first linkage gear 303 drives... The first clamping frame 301 moves, and the second linkage gear 304 drives the second clamping frame 302 to move. The bottom ends of the first clamping frame 301 and the second clamping frame 302 slide within the bracket 3065. The bracket 3065 limits the movement trajectory of the two to prevent deviation. The rotation of the rotating shaft 3062 causes the first clamping frame 301 and the second clamping frame 302 to generate relative movement and adjust the distance between them. The pawl frame 3064 and the ratchet 3063 cooperate to limit the rotation of the rotating shaft 3062 in the opposite direction, maintain the stability of the clamping state, and finally achieve the clamping of the parts transported on the top of the moving block 7.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The bottom of the machine body 1 is equipped with a rib 4. The outer walls of the rib 4 are fixedly connected to the left and right sides of the rib 4. The outer walls of the machine body 1 are fixedly connected to the left and right sides of the rib 4. The top of the multiple protective frames 6 is rectangular. The top of the machine body 1 is provided with limit grooves 8 on the front and rear sides. The multiple limit grooves 8 are rectangular. The top of the machine body 1 is equipped with a moving block 7. The bottom of the outer wall of the moving block 7 is slidably connected to the inside of the limit groove 8. The clamping mechanism 3 is installed inside the moving block 7.

[0037] Specifically, the bottom of the machine body 1 has a rib 4 inside, and fixing blocks 5 are welded to its left and right sides to strengthen the connection between the rib 4 and the machine body 1 and maintain the installation stability of the rib 4. The outer wall of the machine body 1 has a protective frame 6 on both the left and right sides. The central rectangular design can place the drive component inside to avoid damage caused by external collisions. The top front and rear sides of the machine body 1 have limit grooves 8. The multiple limit grooves 8 are all rectangular in design to provide guidance for the sliding of the moving block 7. The support shaft 305 and the bracket 3065 are both fixed inside the moving block 7 to provide stable support for the transmission component in the clamping mechanism 3. The rotating shaft 3062 can rotate inside the moving block 7. All components cooperate with each other to ensure the structural stability of the machine body 1 and the smooth operation of the moving block 7.

[0038] Working principle: Rotating the hexagonal nut 2031 drives the worm 2032 on the outer wall to rotate. Through the meshing of the worm 2032 and the worm wheel 2033, the two worm wheels 2033 drive the lead screw 2034 welded in the middle to rotate synchronously on the inner wall of the machine body 1. The lead screw 2034 is connected to the inside of the fixed arc plate 202 by threads. Due to the rotation restriction of the two lead screws 2034, when the lead screw 2034 rotates, the fixed arc plate 202 can only slide inside the machine body 1 along the axial diameter direction of the lead screw 2034. When the bolt 201 is inserted into the machine body 1 through the fixing block 5, the reinforcing rib is fixed to the bottom of the machine body 1 by the groove fit between the fixed arc plate 202 and the bolt 201 and the self-locking characteristics of the worm 2032 and the worm wheel 2033.

[0039] Rotating the triangular knob 3061 causes the shaft 3062 on the rear side of its outer wall to rotate, which in turn drives the ratchet 3063 welded to the outer wall to rotate. The shaft 3062 drives the first linkage gear 303 to rotate. Through the meshing of the first linkage gear 303 and the second linkage gear 304, the second linkage gear 304 can rotate on the support shaft 305. Since the first linkage gear 303 can drive the first clamping frame 301 to move, and the second linkage gear 304 can drive the second clamping frame 302 to move, and the bottom ends of the first clamping frame 301 and the second clamping frame 302 slide within the bracket 3065, the rotation of the shaft 3062 causes the relative movement of the first clamping frame 301 and the second clamping frame 302. The pawl 3064 can cooperate with the ratchet 3063 to limit the rotation of the shaft 3062 in the opposite direction, ultimately achieving the clamping of the parts transported on the top of the moving block 7.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
