Description

Technical Field

[0001] This utility model relates to the field of CNC machining technology, and in particular to a tensioning component, a motion module, and a machining equipment. Background Technology

[0002] In related technologies, processing equipment such as laser processing equipment, cutting machines, and 3D printers often use synchronous belts for transmission. The two ends of the synchronous belt are connected to a driving pulley and a driven pulley, respectively. The portion of the synchronous belt between the driving and driven pulleys is connected to the processing head. Thus, the driving pulley rotates under the drive of the drive mechanism, and drives the processing head to translate via the synchronous belt, while the driven pulley rotates accordingly. However, after prolonged use, the synchronous belt can loosen, leading to decreased transmission stability. This results in delays and insufficient displacement accuracy of the processing head when the drive mechanism moves the synchronous belt. Utility Model Content

[0048] Please see Figures 1 to 5 This utility model proposes a tensioning assembly 30 for tensioning a synchronous belt 42 in a motion assembly. The tensioning assembly 30 includes: a mounting base 31, a movable member 32, an elastic member 33, and an adjusting structure 34. The movable member 32 is mounted on the mounting base 31 and can move relative to the mounting base 31 in a first direction. The movable member 32 is used to mount the driven wheel 41 in the motion assembly to drive the driven wheel 41 to move. The elastic member 33 is installed between the mounting base 31 and the movable member 32. Under the action of the elastic member 33, the movable member 32 has a tendency to move in the first direction. The adjusting structure 34 is mounted on the mounting base 31 and connected to the elastic member 33 to adjust the elastic force of the elastic member 33.

[0049] In this invention, the driven wheel 41 is mounted on the movable part 32, which is movably mounted on the mounting base 31. Under the action of the elastic member 33, the driven wheel 41 tends to move away from the drive mechanism 20 in the first direction. This allows the driven wheel 41 to adjust its position when the synchronous belt 42 becomes slack, indirectly under the action of the elastic member 33. This ensures that the driven wheel 41 can always keep the synchronous belt 42 taut, thereby ensuring the stability of the synchronous belt 42 and avoiding the problems of delayed response and insufficient displacement accuracy of the processing head 50. At the same time, the adjustment structure can adjust the elastic force of the elastic member so that the tensioning component can always have a good tensioning effect.

[0050] In some embodiments, when the stretch of the timing belt is too large and the movement of the movable member 32 under the elastic force of the elastic member is insufficient to bring the tension of the timing belt back to the ideal state, as long as the movable member has not reached the limit position of its stroke, the adjustment structure 34 can still be adjusted to further increase the compression or tension of the elastic member 33, provide greater tension, and bring the tension of the timing belt back to the ideal state.

[0051] The mounting base 31 can be a plate-shaped, block-shaped, or frame-shaped structure, and can be made of materials such as plastic or metal. The elastic element 33 can be a compression spring, tension spring, torsion spring, elastic rubber block, bellows, rubber band, or other structures. There are various specific implementations of the adjustment structure 34. The adjustment structure 34 can be an electrically driven structure, such as a linear motor or an electro-hydraulic cylinder. One, two, or even more adjustment structures 34 can be provided, depending on the specific circumstances.

[0052] There are many specific ways to install the aforementioned movable part 32 on the mounting base 31. For example, the two can be connected by a sliding rail and groove structure. Or the movable part 32 can be connected to the sliding rail of the mounting base 31 by a roller. In this way, rolling friction is generated when the two move relative to each other, and the friction force is small.

[0053] The movable member 32 and the mounting base 31 can be disposed on opposite sides of the elastic member 33 in the first direction. Specifically, the driven wheel 41 is connected to the side of the movable member 32 away from the mounting base 31, and the elastic member 33 is a tension spring or a compression spring. In this way, the tension spring pulls the movable member 32 or the compression spring pushes the movable member 32, thereby achieving tension of the synchronous belt 42. In some embodiments of this utility model, the movable member 32 includes a body 320 and a receiving part 321. The body 320 is slidably connected to the mounting base 31, and the receiving part 321 is connected to the side of the body 320 perpendicular to the first direction. The elastic member 33 abuts against the receiving part 321. Through the above scheme, the space around the mounting base 31 can be fully utilized, avoiding spatial interference between the elastic member 33 and other components, making the structure of the entire tensioning assembly 30 more compact and the spatial layout more reasonable, which is conducive to miniaturization.

[0054] In some embodiments of this utility model, the mounting base 31 is provided with an assembly part 313 and a sliding groove 316. The sliding groove 316 extends through both sides in the first direction, and the main body 320 is slidably installed in the sliding groove 316. The assembly part 313 is located on one side of the sliding groove 316 perpendicular to the first direction and is positioned opposite to the abutment part 321. The adjustment structure 34 is connected to the assembly part 313 and the abutment part 321. The sliding groove 316 provided in the mounting base 31 extends through both sides in the first direction. On the one hand, the main body 320 of the movable part 32 can easily slide into and be installed in the sliding groove 316 from one side, making assembly more convenient. On the other hand, the processing technology of the sliding groove 316 is relatively simple, which helps to reduce manufacturing costs. The main body 320 can slide smoothly along the first direction in the sliding groove 316, so that the movable part 32 can remain stable during movement, reducing shaking and displacement.

[0055] In some embodiments of this utility model, the assembly part 313 is provided with an assembly space 3130. An avoidance hole 3131 is provided on one side wall of the assembly space 3130 in the first direction. The adjustment structure 34 partially passes through the avoidance hole 3131 into the assembly space 3130, and the elastic member 33 is assembled within the assembly space 3130. The installation of the elastic member 33 and the adjustment structure 34 within the assembly space 3130 makes the layout of the entire tensioning assembly 30 more regular and orderly. Furthermore, both are restricted and protected by the assembly space 3130, making them less prone to displacement or deformation, thus ensuring the stability of their performance. In addition, the avoidance hole 3131 facilitates operation by the operator through the exposed structure of the adjustment structure 34. When it is necessary to adjust the elastic force of the elastic member 33, the operator can directly operate the adjustment structure 34 through the avoidance hole 3131 without disassembling too many parts, improving the convenience of adjustment.

[0056] In some embodiments of this utility model, the assembly space 3130 is at least partially through the side wall away from the clearance hole 3131 in the first direction to avoid the adjustment structure 34 or the elastic member 33. This provides additional operating space for the installation and removal of the adjustment structure 34 and the elastic member 33, avoiding installation difficulties caused by limited space; on the other hand, the overall size of the mounting base 31 does not need to be considered to accommodate the maximum extension length of the adjustment structure 34, so the size of the mounting base 31 can be smaller, which is beneficial to improving the compactness of the structure.

[0057] There are various ways to connect the adjustment structure 34 to the assembly part 313. For example, the adjustment structure 34 is an electric actuator. The housing of the electric actuator can be fixed to the assembly part 313 by welding, screw connection, or other means. It can also be connected by sliding, rotating or other movable means.

[0058] Please see Figures 6 to 10 In some embodiments of this utility model, the adjusting structure 34 includes a connecting member 341 and an adjusting bolt 343. The connecting member 341 is disposed on the assembly part 313 and can slide relative to the assembly part 313. The connecting member 341 has a threaded hole, and the adjusting bolt 343 is threadedly connected to the threaded hole. The elastic member 33 is connected between the abutting part 321 and the connecting member 341. In this way, by rotating the adjusting bolt 343, the displacement of the connecting member 341 can be precisely controlled, thereby precisely adjusting the compression or tension of the elastic member 33, achieving precise adjustment of the elastic force of the elastic member 33, which helps to improve the stability and reliability of the synchronous belt 42 transmission. Among them, the assembly part 313 can constrain the rotation of the connecting member 341, so that when the adjusting bolt 343 rotates, the connecting member 341 will move along the first direction.

[0059] In some embodiments of this utility model, the receiving part 321 is provided with a clearance opening, and the adjusting bolt 343 passes through the clearance hole 3131, the clearance opening and the threaded hole in sequence. In this way, the two ends of the elastic member 33 are pressed by the receiving part 321 and the connecting member 341, and the periphery is limited by the adjusting bolt 343 and the wall of the assembly space 3130, so that the elastic member 33 can stably deform as expected, with high reliability.

[0060] In some embodiments of this utility model, the assembly space 3130 forms a sliding notch 3132 through the sidewall along the second direction, and the abutting part 321 is located within the sliding notch 3132, so that the abutting part 321 can slide within the sliding notch 3132 along the first direction. The abutting part 321 can slide freely within the sliding notch 3132 along the first direction, avoiding obstruction by other components.

[0061] In some embodiments of this utility model, the adjusting structure 34 includes a connector 341, an adjusting bolt 343, and a stop member 342. The connector 341 is connected to the assembly part 313 and has a threaded hole. The adjusting bolt 343 passes through the clearance hole 3131 and is threaded into the threaded hole. One end of the adjusting bolt 343 located in the assembly space 3130 is rotatably connected to the stop member 342. The stop member 342 is slidably assembled in the assembly space 3130 and can slide along a first direction. The elastic member 33 is connected between the abutting part 321 and the stop member 342. When it is necessary to adjust the elastic force of the elastic member 33 to change the tension of the synchronous belt 42, the operator can rotate the adjusting bolt 343. Since the adjusting bolt 343 is threadedly connected to the threaded hole on the connecting piece 341, rotating the adjusting bolt 343 will cause it to move along the first direction. One end of the adjusting bolt 343 located in the assembly space 3130 is rotatably connected to the abutment 342. The axial movement of the adjusting bolt 343 will cause the abutment 342 to slide along the first direction in the assembly space 3130. The sliding of the abutment 342 will compress or stretch the elastic member 33 connected between the abutting part 321 and the abutment 342, thereby changing the elastic force of the elastic member 33, and finally realizing the adjustment of the tension of the synchronous belt 42. The adjustment process is also relatively convenient.

[0062] In some embodiments of this utility model, the assembly space 3130 has an installation opening on one side in the third direction, and the movable component 32 also includes a cover 325, which is connected to one side of the body 320 and covers the installation opening. During installation, these components can be directly placed into the assembly space 3130 through the installation opening without complicated operations or additional disassembly steps, thus improving installation efficiency. The cover 325 is connected to the body 320, which can limit the swaying or offset of the adjustment structure 34 in the third direction and prevent the adjustment structure 34 from falling out, resulting in high structural stability.

[0063] In some embodiments of this utility model, the movable member 32 further includes a sliding hook portion 326, and the mounting base 31 has a hook groove 317 on the side opposite to the movable member 32. One end of the sliding hook portion 326 is connected to the end of the cover portion 325 away from the body 320, and the other end of the sliding hook portion 326 is slidably engaged with the hook groove 317, which extends along the first direction. This arrangement ensures that the movable member 32 can move strictly along the first direction under the elastic force of the elastic member 33 or under the adjustment of the adjustment structure 34, avoiding lateral deviation and making the tensioning operation of the driven wheel 41 on the synchronous belt 42 by the movable member 32 more precise. Moreover, the sliding hook portion 326 connects the cover portion 325 of the movable member 32 to the mounting base 31, forming a relatively stable connection between the movable member 32 and the mounting base 31. While ensuring that the movable member 32 can slide relative to the mounting base 31, it also ensures that the two maintain a certain degree of structural integrity, which helps to improve the structural stability of the entire tensioning assembly 30.

[0064] To further improve the structural compactness, in some embodiments of this utility model, the main body 320 is provided with a mounting groove 323 for mounting the driven wheel 41. The driven wheel 41 can be mounted in the mounting groove 323. The mounting groove 323 has rotating holes 3231 on the opposite sides of the groove wall in the third direction for rotatably connecting the two ends of the axle 412 of the driven wheel 41. The assembly part 313 is provided on one side of the slide groove 316 in the second direction. The third direction, the second direction and the first direction are perpendicular to each other. In this way, the internal space of the moving part 32 is fully utilized for mounting the driven wheel 41, which greatly improves the structural compactness.

[0065] In some embodiments of this utility model, the tensioning assembly 30 further includes a screw connector 35. The body 320 has a limiting hole 322, and the bottom wall of the slide groove 316 also has a positioning hole 314. The screw connector 35 passes through the limiting hole 322 and connects to the positioning hole 314. The limiting hole 322 or the positioning hole 314 extends along a first direction, i.e., the limiting hole 322 or the positioning hole 314 is strip-shaped, so that the screw connector 35 can slide relative to the mounting base 31 along the first direction. The screw connector 35, restricted by the limiting hole 322 and the positioning hole 314, can only slide along the first direction, which helps improve the accuracy of the tension adjustment of the driven wheel 41 on the synchronous belt 42, ensuring that the synchronous belt 42 always maintains a suitable tension and guaranteeing the stability and accuracy of the transmission. In addition, the use of screw connector 35 improves the reliability and service life of tensioning assembly 30. During equipment operation, even if subjected to external forces such as vibration and impact, moving part 32 will not easily fall off the mounting base 31 or shake significantly, reducing the probability of equipment failure.

[0066] In some embodiments of this utility model, two adjusting structures 34 and two elastic elements 33 are provided. The two adjusting structures 34 are respectively located on opposite sides of the body 320 in the second direction. One adjusting structure 34 is connected to one elastic element 33. The second direction is perpendicular to the first direction. Two abutting parts 321 are provided. The two abutting parts 321 are respectively connected to opposite sides of the body 320. One elastic element 33 abuts against one abutting part 321. In this way, the two adjusting structures 34 can ensure that the tension of the synchronous belt 42 on both sides of the driven wheel 41 is balanced, avoiding the problem of the synchronous belt 42 shifting or loosening due to excessive or insufficient tension on one side, and thus improving stability.

[0067] Please see Figure 2 and Figure 3 This utility model also proposes a motion module 10', including a base 10, a drive mechanism 20, a motion component 40, and a tensioning component 30 as described in any of the above embodiments; a mounting base 31 is mounted on the base 10; the motion component 40 includes a drive wheel, a driven wheel 41, and a timing belt 42.

In this way, the drive mechanism 20 drives the timing belt 42 to move, and the driven wheel 41 rotates accordingly.
