Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a timing belt clamp. Background Technology

[0002] As a core component of precision transmission systems, the tensile strength of synchronous belts directly determines the reliability and stability of equipment operation. Under rated load, synchronous belts must withstand dynamic tension and accurately transmit power. If insufficient fracture resistance is caused by material defects or manufacturing errors, transmission failure may occur. For example, a broken synchronous belt in industrial automation equipment can lead to production line shutdown, while a failure of the timing system in a car engine can cause serious mechanical accidents. Therefore, verifying the mechanical properties of synchronous belts through tensile testing is a crucial step in ensuring the safe operation of equipment.

[0003] Most existing timing belt clamps still use the traditional planar clamping block method when clamping and fixing timing belts.

[0004] However, during tensile testing, the planar structure of the clamping block is difficult to perfectly match the tooth profile of the timing belt, resulting in insufficient contact area and uneven pressure distribution during clamping. This localized stress concentration can easily cause the timing belt to slip, which not only reduces testing efficiency but may also cause tooth surface wear due to slippage friction, causing the test results to deviate from the true value and making it impossible to effectively evaluate the actual performance of the timing belt.

The clamping component is used to clamp and fix the timing belt. The outer sleeve is provided with a driving component for driving the clamping component to complete the clamping action.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0023] Example: A timing belt clamp, such as Figures 1-4 As shown, the device includes an outer sleeve 1, a sleeve 2, a timing belt 001, a clamping assembly, and a drive assembly. The sleeve 2 is fixedly connected to the rear side of the outer sleeve 1. The clamping assembly is provided on the outer sleeve 1, and the timing belt 001 is provided on the clamping assembly. The clamping assembly is used to clamp and fix the timing belt 001. The outer sleeve 1 is provided with a drive assembly for driving the clamping assembly to complete the clamping action. The sleeve 2 and the outer sleeve 1 are coaxially arranged, and the sleeve 2 and the outer sleeve 1 are fixedly connected by welding or integral molding to ensure the connection strength and coaxiality between the sleeve and the outer sleeve, making the overall structure more stable and able to withstand greater tensile force.

[0024] like Figure 1 , Figure 2 and Figure 4As shown, the clamping assembly includes clamping blocks 3, toothed clamping plates 4, pressure blocks 5, screws 6, and guide shafts 7. A triangular mounting groove is provided in the middle of the outer sleeve 1. Clamping blocks 3 are movably mounted on both sides of the triangular mounting groove. A toothed clamping plate 4 is fixedly connected to the right side wall of the left clamping block 3. The synchronous belt 001 is clamped and fixed between the toothed clamping plate 4 and the right clamping block 3. The tooth profile of the toothed clamping plate 4 matches the tooth profile of the synchronous belt 001 to ensure good meshing between the toothed clamping plate 4 and the synchronous belt 001. Pressure blocks 5 are provided on both the left and right sides of the outer sleeve 1. Two screws 6 are connected to each pressure block 5 at intervals. Each screw 6 can be screwed into the outer sleeve 1 to fix the pressure block 5 to the outer sleeve 1. The screws 6 are hexagonal socket head cap screws, tightened and loosened using an hexagonal socket head cap wrench. The operation is convenient for workers to install and disassemble, and the tightening torque is controllable, ensuring the reliability of the connection. Guide shafts 7 are fixedly connected to both clamping blocks 3. The guide shafts 7 and clamping blocks 3 are integrally formed, which enhances the connection strength between the guide shafts and clamping blocks and improves the reliability and durability during use. The bottom of both pressure blocks 5 is provided with sliding grooves 8 that cooperate with the adjacent guide shafts 7. The side walls of the triangular mounting grooves are inclined surfaces, which match the contact surfaces of the clamping blocks 3. The adjacent inclined surfaces and sliding grooves 8 have the same inclination angle, thereby guiding the movement of the two clamping blocks 3. The outer sleeve 1, clamping blocks 3, toothed clamping plates 4 and pressure blocks 5 are all made of steel. Steel has high strength and hardness, which can ensure that the clamping components are not easily deformed or damaged when clamping the timing belt.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the drive assembly includes a T-shaped pull rod 9, a connecting shaft 10, a pressure rod 11, and an elastic element 12. The T-shaped pull rod 9 is slidably mounted on the outer sleeve 1. The connecting shaft 10 is slidably mounted on the rear side of the T-shaped pull rod 9. The pressure rod 11 is rotatably connected to the connecting shaft 10. An elastic element 12 is connected between the T-shaped pull rod 9 and the outer sleeve 1. The elastic element 12 is a return spring. The elastic element 12 is sleeved on the T-shaped pull rod, and both ends of the elastic element 12 abut against the T-shaped pull rod and the outer sleeve, respectively. When the external force is removed, the elastic element 12 can push the T-shaped pull rod to return to its original position.

[0026] Working principle: First, the operator assembles the fixture, connecting the elastic element 12, connecting shaft 10, and pull rod, and then inserts the pull rod into the outer cylinder. Next, the pressure rod 11 is connected to the pull rod at the connecting shaft 10. Then, two clamping blocks 3 are placed on the left and right sides of the triangular mounting groove on the outer sleeve 1. The front side of the T-shaped pull rod 9 passes through the openings in the two clamping blocks 3. The left clamping block 3 is fixedly equipped with a toothed clamping plate 4. Finally, the two pressure blocks 5 are fixed to the outer sleeve 1 with screws 6. On both sides, align the groove 8 on the bottom plate of the pressure plate with the guide shaft 7 on the adjacent pressing block, and finally connect the sleeve 2 to the external tensioning instrument to complete the assembly process. In use, press the pressure rod 11 forward, thereby prying the T-shaped pull rod 9 backward through the connecting shaft 10. At this time, the elastic element 12 is compressed, and the two pressing blocks also move backward along with the T-shaped pull rod 9. While the pressing blocks move backward, due to the cooperation of the guide shaft 7 and the groove 8, the two pressing blocks are driven to move backward... While moving, the clamp opens to the left and right sides, allowing the synchronous belt 001 to be placed between the toothed clamp 4 and the clamping block 3 on the right. Then, the pressure rod 11 is released, and under the reset action of the elastic element 12, the T-shaped pull rod 9 pushes the two clamping blocks 3 forward to reset. Simultaneously, under the cooperation of the guide shaft 7 and the sliding groove 8, they move closer together, fixing and clamping the synchronous belt 001. A tensile test can then be performed. Because the toothed clamp 4 meshes with the synchronous belt 001, the contact area between the clamp and the synchronous belt 001 is increased, ensuring that the tensile force is evenly distributed on each tooth, increasing the clamping force, and preventing slippage. This also avoids measurement errors caused by localized stress concentration. During tensile testing, the combination of toothed meshing and wedge-shaped pressure reduces direct pressure damage to the surface of the synchronous belt 001 while avoiding damage caused by sudden excessive pressure. Because the clamping is more stable and uniform, the synchronous belt 001 is less prone to shifting or breaking during the test, thus improving the reliability and repeatability of the test results.
