Description
Technical Field
[0001] This utility model relates to the field of work technology, and in particular to a precise positioning device for a pulley drive in blade processing. Background Technology
[0002] In the field of cutting tool manufacturing, as the manufacturing industry's requirements for the precision and quality of cutting tools continue to rise, the precise positioning device of the pulley drive plays a crucial role. The cutting tool manufacturing process involves multiple steps such as cutting, grinding, and polishing. In these steps, the pulley drive mechanism needs to accurately deliver the cutting tool to the processing position to ensure that the processing accuracy is controlled within a very small tolerance range. For example, in the edge grinding stage of precision cutting tools, if the positioning deviation exceeds ±0.01mm, it may lead to uneven edge angle, which will seriously affect the cutting performance and service life of the tool.
[0003] Currently, common precision positioning devices using pulley drives inevitably experience vibrations during operation. These vibrations occur due to factors such as uneven mass distribution, belt tension variations, and the coordinated operation with other components of the cutting tool processing equipment. These vibrations are transmitted to the base via the pulley drive mechanism, causing the entire device to shake. Traditional positioning device bases are mostly rigid structures, relying solely on simple rubber feet or low-strength shock-absorbing pads for vibration reduction, which is insufficient to effectively suppress vibration transmission. On one hand, vibration can cause slight displacement deviations during pulley drive, making it difficult to guarantee the positioning accuracy of the cutting tool during processing. This ultimately affects key quality indicators such as the dimensional accuracy and surface roughness of the cutting tool. On the other hand, long-term vibration can also accelerate the wear of various components in the device, shortening the belt's lifespan. Frequent belt replacements not only increase production costs but also affect processing efficiency. Utility Model Content

This device can solve the problem that vibration can cause slight displacement deviations during the pulley drive process, making it difficult to guarantee the positioning accuracy of the blade during processing. Ultimately, this affects key quality indicators such as the dimensional accuracy and surface roughness of the blade. On the other hand, long-term vibration can also cause accelerated wear of various components of the device, resulting in a shortened belt life. Frequent belt replacement not only increases production costs but also affects processing efficiency.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a precise positioning device for blade processing using a pulley drive, comprising a mounting base 1, a mounting plate 2, and a pulley drive mechanism 3;
[0030] The mounting base 1 is equipped with a shock-absorbing component inside;
[0031] The damping assembly includes a sliding connecting seat 5 and three dampers 13. A sliding connecting seat groove 16 is formed on the upper surface of the mounting base 1. All three dampers 13 are installed inside the sliding connecting seat groove 16. The outer wall of the sliding connecting seat 5 is slidably connected to the inside of the sliding connecting seat groove 16. The ends of the three dampers 13 closest to the sliding connecting seat 5 are fixedly connected to the lower surface of the sliding connecting seat 5. Six fixing rod grooves 15 are formed inside the sliding connecting seat groove 16. The six fixing rod grooves 15 are arranged in groups of three, and each group of three fixing rod grooves 15 has a fixing rod fixedly connected inside. The outer walls of the two sets of fixed rods 9 are slidably connected to movable seats 11. The upper ends of the two sets of movable seats 11 are rotatably connected to connecting rods 10. The lower surface of the sliding connecting seat 5 is fixedly connected to six fixed seats 12, which are in groups of three. The outer walls of the two sets of connecting rods 10 away from the movable seats 11 are rotatably connected to the lower ends of the corresponding fixed seats 12. The outer walls of the two sets of fixed rods 9 are fitted with buffer springs 14. The two ends of the two sets of buffer springs 14 are fixedly connected to the inner walls of the corresponding fixed rod grooves 15 and the outer walls of the movable seats 11, respectively.
[0032] Two T-shaped blocks 6 are fixedly connected to the lower surface of the mounting base plate 2. The leather wheel transmission mechanism 3 is fixedly installed on the upper surface of the mounting base plate 2. Two T-shaped block grooves 7 are opened on the upper surface of the sliding connection seat 5. The outer walls of the two T-shaped blocks 6 are slidably connected to the interior of the corresponding T-shaped block grooves 7. A fixing bolt groove 8 is opened on the inner wall of one end of each of the two T-shaped block grooves 7. Two fixing bolts 4 are threadedly connected to the upper surface of the mounting base plate 2. The ends of the two fixing bolts 4 near the fixing bolt grooves 8 are threaded to the outside of the mounting base plate 2 and the T-shaped blocks 6 and are respectively threadedly connected to the interior of the corresponding fixing bolt grooves 8.
[0033] Furthermore, when using this device, it is started by connecting to an external power source. During the blade processing, the pulley transmission mechanism 3 is fixedly installed on the upper surface of the mounting base plate 2. The pulley transmission enables power transmission and precise positioning of the blade processing. The mounting base plate 2 is slidably connected to the T-shaped block groove 7 on the sliding connecting seat 5 via the T-shaped block 6 on its lower surface. Then, the fixing bolt 4 passes through the mounting base plate 2 and the T-shaped block 6 and is threadedly connected to the fixing bolt groove 8 on the sliding connecting seat 5, thus firmly installing the mounting base plate 2 on the sliding connecting seat 5. Next, the pulley transmission mechanism 3 is installed in the designated position via the mounting seat 1. Then, when the device is subjected to external vibration or vibration generated during processing, the vibration is first transmitted to the mounting base plate 2, and then transmitted to the sliding connecting seat 5 via the mounting base plate 2. The moving connecting seat 5 moves up and down within the sliding connecting seat groove 16. The three dampers 13 function by consuming vibration energy through their own damping characteristics, thus reducing the vibration amplitude of the sliding connecting seat 5. The vibration of the sliding connecting seat 5 is transmitted to the connecting rod 10 through the fixed seat 12. The connecting rod 10 drives the moving seat 11 to slide on the fixed rod 9, compressing or stretching the buffer spring 14. The buffer spring 14 absorbs and stores vibration energy through deformation, further buffering the vibration. The sliding of the moving seat 11 and the fixed rod 9, the rotation of the connecting rod 10, and the deformation of the buffer spring 14 work together to enable the entire shock absorption assembly to effectively absorb and disperse vibration, reduce the impact of vibration on the pulley transmission mechanism 3, and ensure that the pulley transmission mechanism 3 works in a stable environment, thereby achieving precise positioning of the cutting tool.
[0034] When the device is subjected to external vibration or vibration generated during processing, the vibration is first transmitted to the mounting base plate 2. At this time, the sliding connecting seat 5 moves up and down in the sliding connecting seat groove 16. The three dampers 13 play a role, consuming vibration energy through their own damping characteristics and reducing the vibration amplitude of the sliding connecting seat 5. At the same time, the sliding of the moving seat 11 and the fixed rod 9, the rotation of the connecting rod 10, and the deformation of the buffer spring 14 work together to enable the entire vibration damping assembly to effectively absorb and disperse vibration, reduce the impact of vibration on the pulley transmission mechanism 3, and ensure that the pulley transmission mechanism 3 works in a stable environment, thereby achieving precise positioning of the blade processing and improving the practicality of the equipment.
[0035] Structural Description: Mounting base 1: It is the basic load-bearing component of the entire device, providing installation support for other components. It is equipped with a shock-absorbing component inside, and the upper surface has a sliding connection seat groove 16 for installing the sliding connection seat 5 and other components in the shock-absorbing component. At the same time, it provides a positioning foundation for the installation of the mounting base plate 2, ensuring the stability of the overall structure of the device.
[0036] Sliding connecting seat 5: The outer wall of the sliding connecting seat 5 is slidably connected to the sliding connecting seat groove 16 on the mounting seat 1. It can move up and down in the groove. It is a key structure in the shock absorption assembly that connects the mounting base plate 2 and the shock absorption component. Its lower surface is connected to the damper 13 and the fixed seat 12, and its upper surface is connected to the mounting base plate 2 through the T-shaped block groove 7. It plays the role of transmitting and dispersing force during the shock absorption process.
[0037] Dampers 13: Three dampers 13 are installed inside the sliding connection seat groove 16, with one end fixedly connected to the lower surface of the sliding connection seat 5. The dampers 13 consume vibration energy through their own damping characteristics, reduce the vibration amplitude of the sliding connection seat 5, effectively suppress vibration transmission, and provide shock absorption and buffering function for the device.
[0038] Fixed rod 9: Two sets of fixed rods 9 are fixed in the six fixed rod slots 15 in the sliding connection seat slot 16, three in each set. The fixed rods 9 provide a sliding track for the moving seat 11 and also serve as a support component for the buffer spring 14. Together with the moving seat 11, connecting rod 10, fixed seat 12, etc., they form a shock absorption structure and assist the damper 13 in achieving the shock absorption effect.
[0039] Movable seat 11: Two sets of movable seats 11 are respectively fitted on the outer walls of two sets of fixed rods 9 and can slide along them. The upper end of the movable seat 11 is rotatably connected to the connecting rod 10. Through cooperation with the connecting rod 10 and the fixed seat 12, when the device is vibrated, it can move up and down along the fixed rod 9 to compress or stretch the buffer spring 14 and absorb and buffer the vibration energy.
[0040] Connecting rod 10: Two sets of connecting rods 10 are rotatably connected to the movable seat 11 and the fixed seat 12 respectively. During the movement of the movable seat 11, the angle is adjusted by rotation to ensure effective force transmission, so that the shock absorption structure can flexibly adapt to vibrations in different directions and enhance the shock absorption effect.
[0041] Fixed seat 12: Six fixed seats 12 are fixed in groups of three on the lower surface of the sliding connecting seat 5. They are used to rotate and connect with the connecting rod 10, and transmit the vibration of the sliding connecting seat 5 to the moving seat 11 and the buffer spring 14. They are important nodes for force transmission in the shock absorption structure.
[0042] Buffer spring 14: Two sets of buffer springs 14 are respectively sleeved on the outer walls of two sets of fixed rods 9, and their two ends are respectively fixedly connected to the inner wall of the fixed rod groove 15 and the outer wall of the movable seat 11. When the device is subjected to vibration, the buffer spring 14 absorbs and stores vibration energy by compression or stretching deformation. When the vibration weakens, it releases energy to restore the device to balance. It works in conjunction with the damper 13 to improve the vibration reduction performance.
[0043] Mounting base plate 2: Two T-shaped blocks 6 are fixedly connected to the lower surface and slidably connected to the T-shaped block groove 7 on the upper surface of the sliding connecting seat 5 to realize the connection between the mounting base plate 2 and the shock absorption component. The upper surface is fixedly mounted with the pulley transmission mechanism 3 and fixed to the sliding connecting seat 5 by two fixing bolts 4 to ensure the stability of the pulley transmission mechanism 3 during operation. The threaded connection between the fixing bolts 4 and the fixing bolt groove 8 can ensure that the mounting base plate 2 and the sliding connecting seat 5 are tightly connected to prevent loosening during vibration or operation.
[0044] Pulley transmission mechanism 3: Fixedly installed on the upper surface of mounting base plate 2, it is the core functional component for transmission and precise positioning during blade processing. Through the transmission characteristics of the pulley, power is transmitted to the blade processing area to achieve precise processing operation.
[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
