Description

Technical Field

[0001] This utility model relates to the field of guide rails, and specifically to a belt tension adjustment guide rail. Background Technology

[0002] Synchronous belt modules are widely used in industrial automation production and numerous mechanical equipment to achieve precise linear motion and power transmission. During prolonged continuous operation, synchronous belts are prone to loosening due to repeated stretching, friction, and mechanical vibration. Once the synchronous belt loosens, it severely affects the accuracy of equipment operation, causing deviations in the transmission coordination between mechanical components and reducing the overall performance of the equipment.

[0003] Currently, the conventional approach to resolving timing belt loosening issues is to remove the timing belt from the equipment and then readjust its position within the module to restore its tension. However, this method is cumbersome, requiring specialized personnel with specific tools for disassembly and reinstallation, resulting in significant time and labor costs. Therefore, developing a belt tensioning guide that allows for convenient and quick tension adjustment without disassembling the timing belt is of substantial practical importance.

The side end of the guide rail slider is provided with a locking bolt. The position of the clamping block is fixed by the locking bolt.

[0006] In a further improvement, the guide rail slider has a through groove inside, and the upper end of the groove has a position adjustment groove. The clamping block includes a pre-tightening part and a sliding part. The sliding part is integrally fixed to the lower end of the pre-tightening part. The pre-tightening part is located in the position adjustment groove. The pre-tightening part has a stepped through hole.

[0017] The following describes the embodiments and appendices. Figures 1-3 The technical solution of this utility model will be further described below.

[0018] Example 1

[0019] A belt tension adjustment guide rail includes: a guide rail slider 1 and a clamping block 2. The clamping block 2 is symmetrically slidably disposed on both sides of the guide rail slider 1. The clamping block 2 has a toothed belt clamping groove 21 inside. The upper end of the guide rail slider 1 is provided with a clamping bolt 11. By screwing in the clamping bolt 11, the clamping block 2 is pushed to clamp the belt located in the toothed belt clamping groove 21. The side end of the guide rail slider 1 is provided with a locking bolt 12. The position of the clamping block 2 is fixed by the locking bolt 12.

[0020] like Figures 1-3 As shown, the working principle of this utility model is as follows:

[0021] This belt tension adjustment guide mainly consists of a guide rail slider 1 and a clamping block 2. The clamping block 2 is symmetrically slidably disposed on both sides of the guide rail slider 1. The clamping block 2 has a toothed belt clamping groove 21 inside, which is used to place and clamp the timing belt.

[0022] A locking bolt 12 is provided on the side end of the guide rail slider 1. Tightening the locking bolt 12 makes it engage with the threaded hole on the side end of the guide rail slider 1, fixing the position of the clamping block 2 and preventing it from shifting during equipment operation, thus ensuring that the synchronous belt always maintains a suitable tension. After the position of the synchronous belt is defined, a clamping bolt 11 is provided on the upper end of the guide rail slider 1. When the clamping bolt 11 is tightened, it will push the clamping block 2 downward, thereby clamping the synchronous belt located in the toothed belt clamping groove 21, ensuring the stability of the synchronous belt.

[0023] This structural design allows for adjustment of the timing belt tension in its original position without removing it from the equipment. The operation is simple, requiring only the rotation of the tightening and locking bolts, significantly saving time and labor costs. Simultaneously, it enables precise adjustment of the timing belt tension, ensuring equipment operating accuracy and improving overall equipment performance and stability.

[0024] As a further preferred embodiment, the guide rail slider 1 has a through groove 11 inside, and the upper end of the groove 11 is provided with a position adjustment groove 12. The clamping block 2 includes a pre-tightening part 23 and a sliding part 22. The sliding part 22 is integrally fixed to the lower end of the pre-tightening part 23. The pre-tightening part 23 is located in the position adjustment groove 12. The pre-tightening part 23 is provided with a stepped through hole 231. The position adjustment groove 12 is provided with a threaded hole 31 coaxial with the stepped through hole 231. The locking bolt 12 passes through the stepped through hole 231 and is threaded into the threaded hole 31. The head of the locking bolt 12 is located in the stepped through hole 231.

[0025] The locking bolt 12 is threaded into the threaded hole 31. The sliding part 22 is located in the slide groove 11. The toothed belt clamping groove 21 is located in the sliding part 22. The top of the guide rail slider 1 is provided with a threaded hole 32. The lower end of the threaded hole 32 extends into the slide groove 11. The clamping bolt 11 is threaded into the threaded hole 32.

[0026] When adjusting the tension of the timing belt, first loosen the clamping bolt, then loosen the locking bolt. Next, move the clamping block along with the timing belt within the groove of the guide rail slider to adjust the tension. After adjusting to the appropriate position, pre-tighten the locking bolt, then pre-tighten the clamping bolt. This design further optimizes the connection and adjustment method between the clamping block and the guide rail slider. The groove and position adjustment groove ensure smoother and more precise movement of the clamping block, guaranteeing even force distribution on the timing belt during clamping and preventing damage from excessive localized force. Simultaneously, the threaded connection used to fix the locking bolt and clamping bolt ensures stability after adjustment and improves the reliability of equipment operation.

[0027] As a further preferred embodiment, two sets of threaded holes 31 are symmetrically arranged on each side of the position adjustment groove 12. Two sets of threaded holes 32 are symmetrically arranged on the top of the guide rail slider 1 on each side.

[0028] When adjusting the tension of the timing belt, the symmetrical locking bolts on both sides engage with the pre-tightening part of the clamping block through their corresponding threaded holes. When adjusting the position of the clamping block, loosen the locking bolts on both sides and adjust the position of the clamping block by rotating the clamping bolts. After adjustment, tighten the locking bolts on both sides to simultaneously clamp the belt from both sides; the two symmetrical clamping bolts act simultaneously on the pre-tightening part of the clamping block. Rotating these two clamping bolts causes them to push the clamping block downwards synchronously, moving it evenly inwards and clamping the timing belt.

[0029] The two sets of symmetrically arranged threaded holes and locking bolts enable the clamping block to be subjected to more even force when fixed, preventing the clamping block from tilting or shifting due to unilateral force, further improving the stability and accuracy of synchronous belt tension adjustment, and ensuring long-term stable operation of the equipment.

[0030] The two sets of symmetrically arranged threaded holes and clamping bolts ensure that the clamping blocks are pushed to clamp the timing belt, and the force is uniform and balanced. This avoids the problem of the timing belt twisting or excessive local force during clamping due to uneven force, thus better protecting the timing belt, improving the service life of the timing belt and the stability of equipment operation.

[0031] As a further preferred embodiment, the guide rail slider 1 has guide rail grooves 13 on both sides inside. The guide rail slider is mounted on the guide rail by sliding and fitting together in a way that achieves stable sliding.

[0032] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
