Description

Technical Field

[0001] This utility model relates to a crankshaft assembly standing alignment machine, which belongs to the field. Background Technology

[0002] Currently, most longitudinal alignment machines use vibratory motors as their vibration source. However, these vibratory motors have some limitations in practical applications. The working principle of a vibratory motor is to generate centrifugal force through the rotation of an eccentric block, thereby causing the motor itself to vibrate. Since the mass and distribution of the eccentric block are fixed, the vibration amplitude and frequency of the vibratory motor are also relatively fixed, making it difficult to flexibly adjust according to different production needs. In some production scenarios requiring precise vibration control, this fixed vibration characteristic cannot meet the requirements for orderly material arrangement, leading to problems such as material accumulation, jamming, or uneven arrangement on the vibration platform, seriously affecting production efficiency and product quality.

[0003] The vibration direction of vibratory motors also has certain limitations. Typically, the vibration direction of a vibratory motor is a straight line along the motor axis. This single vibration direction is difficult to adapt to materials of different shapes, weights, and materials. In actual production, different materials have different sensitivities to vibration direction, and some materials may require multi-directional composite vibration to achieve a good arrangement effect. However, due to the limitations of its structure and operating principle, vibratory motors cannot provide multi-directional vibration, resulting in a significant reduction in the performance of the entire arrangement machine when handling such materials. Furthermore, during operation, the vibration direction of a vibratory motor is easily affected by factors such as motor installation accuracy and operating conditions, and long-term operation can easily lead to vibration direction deviations. This not only affects the material arrangement accuracy but may also cause collisions or friction between the vibratory platform and other parts of the equipment, thereby damaging the equipment, increasing maintenance costs, and reducing equipment downtime.

[0004] Besides the issues of vibration direction and effect, vibratory motors also face the risk of unstable vibration frequency during long-term operation. The stability of the vibration frequency is crucial for the normal operation of the material handling machine, directly affecting the material arrangement speed and accuracy. However, after prolonged operation, the vibration frequency of a vibratory motor often fluctuates due to wear and aging of internal components and interference from external environmental factors. This frequency instability leads to changes in the motion state of the material on the vibrating platform, resulting in inconsistent arrangement and unstable speed, severely impacting the continuity and stability of production. Simultaneously, vibratory motors have poor heat dissipation performance; after prolonged operation, the motor temperature rises, further accelerating the aging and wear of components, creating a vicious cycle that further reduces the reliability and lifespan of the equipment.

[0014] The present invention will be further described below with reference to specific embodiments, and the advantages and features of the present invention will become clearer as a result of the description. However, these embodiments are merely exemplary and do not constitute any limitation on the scope of the present invention. Those skilled in the art should understand that modifications or substitutions can be made to the details and form of the technical solution of the present invention without departing from the spirit and scope of the present invention, but all such modifications and substitutions fall within the protection scope of the present invention.

[0015] See Figures 1 to 3 This utility model relates to a crankshaft assembly standing alignment machine, including a bottom fixing plate 1, which is mounted on a frame; a vibration platform 2, with several support columns installed between the vibration platform 2 and the bottom fixing plate 1, and the vibration platform 2 is mounted on the support columns via linear guide bearings 3; a crankshaft fixing seat 4, fixed to the bottom fixing plate 1; and a crankshaft assembly 5, which includes a crankshaft and an upper crank cam block 51 and a lower crank cam block 52 mounted on the crankshaft, the crankshaft being rotatably mounted on the crankshaft fixing seat 4. The upper crank cam block 51 and the lower crank cam block 52 are mounted on the crankshaft; the upper crank cam block 51 is fixedly connected to the crankshaft, and the lower crank cam block 52 is rotatably engaged with the crankshaft; the upper traction block 6 is mounted on the lower end face of the vibration platform 2, and the upper crank cam block 51 is in rolling engagement with the upper traction block 6; the lower traction block 7 is mounted on the counterweight block 8, and the lower crank cam block 52 is hinged to the lower traction block 7; the vibration motor 9 drives the crankshaft assembly 5 to rotate through the transmission mechanism.

[0016] By using the rolling engagement between the upper crank cam block and the upper traction block, and the hinged engagement between the lower crank cam block and the lower traction block, the consistency between the vibration platform and the product's jumping direction is achieved, thereby improving the efficiency and accuracy of material arrangement.

[0017] The rotation of the crankshaft assembly drives the vibration platform and the counterweight to move in opposite directions, forming up-and-down opposing vibrations. This effectively balances the forces generated by the vibrations, making the equipment run more smoothly, reducing equipment sway and vibration, and improving the stability and service life of the equipment.

[0018] The vibration motor directly drives the crankshaft assembly to rotate through a transmission mechanism (such as a synchronous pulley and synchronous belt). This transmission method can reduce energy loss, improve transmission efficiency, and ensure that the vibration frequency and amplitude of the vibration platform are more stable, thereby improving the working efficiency and reliability of the entire machine.

[0019] The transmission mechanism includes a vibration motor synchronous pulley 91, a crankshaft assembly synchronous pulley 53, and a synchronous belt. The vibration motor synchronous pulley 91 is mounted on the power shaft of the vibration motor 9, and the crankshaft assembly synchronous pulley 53 is mounted on the crankshaft. The crankshaft assembly synchronous pulley 53 and the vibration motor synchronous pulley 91 are connected by a synchronous belt drive.

[0020] Synchronous belt drive can ensure accurate transmission ratio between the vibration motor and the crankshaft assembly, and ensure stable and consistent rotation speed of the crankshaft assembly and vibration frequency of the vibration platform, thereby improving the working accuracy and reliability of the entire machine.

[0021] Compared to other transmission methods such as gear transmission, synchronous belt transmission generates less noise during operation, which helps improve the working environment and reduce noise pollution to operators and the surrounding environment.

[0022] The linear guide bearings 3 are in four sets, symmetrically distributed between the vibrating platform 2 and the bottom fixed plate 1. This symmetrical distribution of the four sets of linear guide bearings significantly enhances the stability of the vibrating platform, ensuring smooth up-and-down movement during vibration. It avoids uneven material arrangement caused by platform tilting or swaying, thereby improving the working accuracy and reliability of the alignment machine.

[0023] It also includes an external protective cover 11, which surrounds the counterweight 8 and the vibration motor 9. The design of the external protective cover effectively enhances the safety of the equipment. It encloses critical components such as the counterweight and vibration motor, preventing operators from accidentally contacting these moving parts during equipment operation and reducing the risk of workplace accidents. At the same time, the protective cover also prevents external debris from entering the equipment, avoiding equipment malfunctions caused by foreign object interference, and improving the operational stability and service life of the equipment.

[0024] The rotation axis of the crankshaft assembly 5 is parallel to the plane of the bottom fixed plate 1. This structural design ensures that the crankshaft assembly can generate a stable vibration effect when rotating. Because the rotation axis is parallel to the bottom fixed plate, the motion trajectory of the vibration platform is more stable, reducing shaking and vibration during equipment operation. This results in a more uniform and orderly arrangement of materials on the vibration platform, improving the overall performance of the entire machine.

[0025] This utility model's crankshaft assembly standing alignment machine achieves efficient and stable material alignment through the synergistic effect of its various components. Its working principle is as follows: After the vibration motor 9 starts, it drives the crankshaft assembly 5 to rotate through the transmission mechanism. The transmission mechanism consists of the vibration motor synchronous pulley 91, the crankshaft assembly synchronous pulley 53, and the synchronous belt, ensuring that the power of the vibration motor 9 is accurately and stably transmitted to the crankshaft assembly 5. The crankshaft assembly 5 is the core component of the entire machine, consisting of a crankshaft, an upper crank cam block 51, and a lower crank cam block 52. When the crankshaft rotates, the upper crank cam block 51 rolls with the upper traction block 6 mounted on the lower end face of the vibration platform 2, pushing the vibration platform 2 up and down along the support column. At the same time, the lower crank cam block 52 is hinged to the lower traction block 7 mounted on the counterweight block 8, driving the counterweight block 8 to move in the opposite direction to the vibration platform 2. This up-and-down opposing vibration design effectively balances the force generated by the vibration, ensuring smooth operation of the equipment, reducing shaking and vibration, and improving the stability and service life of the equipment.

[0026] The vibrating platform 2 is mounted on the support column via four sets of symmetrically distributed linear guide bearings 3. This design not only enhances the stability of the vibrating platform 2's movement but also ensures its linearity and smoothness. The number and symmetrical distribution of the linear guide bearings 3 enable the vibrating platform 2 to remain stable during up-and-down vibration, avoiding problems such as uneven material arrangement caused by tilting or swaying.

[0027] In addition, the external protective cover 11 encloses key components such as the counterweight 8 and the vibration motor 9, which on the one hand prevents operators from accidentally contacting the moving parts and ensures operational safety; on the other hand, it prevents external debris from entering the equipment, avoids equipment failure, and improves operational stability.

[0028] The rotation axis of the crankshaft assembly 5 is parallel to the plane of the bottom fixed plate 1. This structural design ensures that the crankshaft assembly 5 can generate a smooth vibration effect when rotating. The motion trajectory of the vibration platform 2 is more stable, making the material arrangement on the vibration platform more uniform and orderly, thus improving the overall performance of the entire machine.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
