Description

Technical Field

[0001] This utility model relates to the technical field of crankshaft processing, and in particular to a crankshaft shot blasting machine with automatic loading and unloading. Background Technology

[0002] The crankshaft is the most important component in an engine. It bears the force transmitted from the connecting rod and converts it into torque, which is then output through the crankshaft to drive other accessories on the engine. The crankshaft is subjected to the combined effects of centrifugal force from the rotating mass, periodically changing gas inertial force, and reciprocating inertial force, which subject the crankshaft to bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surface must be wear-resistant, have uniform operation, and good balance. Shot blasting the crankshaft surface can effectively improve the surface roughness and hardness, thereby improving the crankshaft's wear resistance and service life.

[0003] When shot blasting crankshafts, the crankshafts must be manually placed into the machine and removed after shot blasting. This increases the labor intensity of workers and reduces work efficiency. Therefore, robotic arms or lifting devices are usually used to assist in loading and unloading. However, these methods have many problems: on the one hand, they are complex in structure, cumbersome in operation, and costly; on the other hand, when using robotic arms, the positioning accuracy of the crankshaft is extremely high. If the positioning is inaccurate, the crankshaft is easily damaged during shot blasting, affecting the shot blasting effect. In addition, the robotic arm needs to be adjusted for crankshafts of different sizes, and the number of crankshafts that can be loaded at one time is limited, making it difficult to achieve efficient batch processing. When using lifting devices for loading and unloading, the crankshaft needs to be suspended on the lifting device, which prevents the contact surface between the crankshaft and the lifting device from being shot blasted, affecting the shot blasting effect. Furthermore, the use of lifting devices also poses safety hazards. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1-4 As shown, the present invention proposes a crankshaft shot blasting machine with automatic loading and unloading, comprising a shot blasting machine 1 and a conveying mechanism 2.

[0017] The conveying mechanism 2 includes a baffle 21, a support frame 22, a first motor 23, a conveyor belt 24, a second motor 25, a perforated turning belt 26, and a pusher plate 27. The baffle 21 is located on one side of the shot blasting machine 1, the support frame 22 is located on the outer wall of the baffle 21, the first motor 23 is located on the outer wall of the baffle 21, the conveyor belt 24 is connected to the shaft of the first motor 23, the second motor 25 is located on the outer wall of the shot blasting machine 1, the perforated turning belt 26 is connected to the shaft of the second motor 25, and the pusher plate 27 is located on the outer wall of the perforated turning belt 26. It should be noted that the aperture of the perforated turning belt 26 should be slightly larger than the diameter of the shot to ensure that the shot can pass through smoothly and fall below for collection.

[0018] In one embodiment of this application, such as Figure 3 As shown, an isolation assembly 3 is installed on the outer wall of the shot blasting machine 1. The isolation assembly 3 includes a fixed plate 31, a cylinder 32, a push plate 33, and an isolation plate 34; the fixed plate 31 is disposed on the outer wall of the shot blasting machine 1, the cylinder 32 is disposed on the fixed plate 31, the push plate 33 is connected to the output end of the cylinder 32, and the isolation plate 34 is disposed on the bottom wall of the push plate 33.

[0019] In one embodiment of this application, such as Figure 3 As shown, a slider 35 is provided on the outer wall of the isolation plate 34, and a guide rail 36 is provided on the outer wall of the shot blasting machine 1. The slider 35 and the guide rail 36 make the isolation plate 34 move more smoothly, avoiding damage to the shot blasting machine 1 due to shaking or deviation. At the same time, they also improve the accuracy of the isolation plate 34 in closing and opening the inlet and outlet, ensuring the smooth progress of shot blasting.

[0020] In one embodiment of this application, such as Figure 4 As shown, an anti-blocking plate 4 is provided on the outer wall of the baffle 21. By providing the anti-blocking plate 4, the crankshaft is effectively prevented from getting stuck between the conveyor belt 24 and the perforated turning belt 26 during the feeding and discharging process.

[0021] In one embodiment of this application, such as Figure 1As shown, a control cabinet 5 is installed on the outer wall of the shot blasting machine 1. As the control center of the entire equipment, the control cabinet 5 not only controls the start, stop and operation of the first motor 23 and the second motor 25, but also handles the data processing and feedback of the monitor 7. Operators can monitor the operating status of the equipment and the progress of shot blasting in real time through the display screen on the control cabinet 5.

[0022] In one embodiment of this application, such as Figure 1 As shown, a fixed bracket 6 is provided on the outer wall of the baffle 21. The fixed bracket 6 is used to install and fix the monitor 7, ensuring that the monitor 7 can stably count and monitor the crankshaft on the conveyor belt 24, thereby improving the automation level and accuracy of the equipment.

[0023] In one embodiment of this application, such as Figure 1 As shown, a monitor 7 is installed on the bottom wall of the fixed bracket 6. As the core component for counting and monitoring, the monitor 7 employs high-precision sensor technology to accurately monitor the number and position of crankshafts on the conveyor belt 24 in real time. This ensures that the number of crankshafts processed in each shot blasting operation reaches the preset value, avoiding uneven processing or low efficiency caused by too many or too few crankshafts. Simultaneously, the monitor 7 also has data processing and feedback functions, transmitting the monitored data to the control cabinet 5 in real time. The control cabinet 5 then judges and processes the data according to a preset program, achieving intelligent control and automated operation of the equipment.

[0024] The working principle of this utility model is as follows: When shot blasting is required on the crankshaft, the operator first places the crankshaft on the conveyor belt 24, and then starts the first motor 23 through the control cabinet 5. The output end of the first motor 23 drives the conveyor belt 24 to rotate, conveying the crankshaft to the perforated turning belt 26 inside the shot blasting machine 1. Then, the second motor 25 is started through the control cabinet 5. The output end of the second motor 25 drives the perforated turning belt 26 to reciprocate, so that the crankshaft rolls on the perforated turning belt 26, thereby performing shot blasting on the crankshaft from all directions, avoiding dead corners, and improving the uniformity and efficiency of shot blasting. After the crankshaft has undergone shot blasting, the second motor 25 stops reciprocating and begins unidirectional rotation. The output of the second motor 25 drives the perforated turning belt 26 for unidirectional conveying, transporting the processed crankshaft to the conveyor belt 24 on the other side of the shot blasting machine 1. The pusher plate 27 pushes the crankshaft from the perforated turning belt 26 onto the conveyor belt 24, preventing it from rolling and accumulating on the belt. Simultaneously, the control cabinet 5 and monitor 7 allow the control cabinet 5 to set the number of crankshafts processed per cycle. When the conveyor belt 24 transports the crankshaft into the shot blasting machine 1, the monitor 7 counts the number of crankshafts. When the preset number of crankshafts to be processed in a single run is reached, the control cabinet 5 will automatically stop the first motor 23 after a delay, ensuring that the last crankshaft is just delivered into the shot blasting machine 1, thus improving the level of automation. After the crankshafts are processed and the processed parts inside the shot blasting machine 1 are transported out of the machine, the control cabinet 5 will restart the first motor 23 to deliver the next crankshaft to be processed into the shot blasting machine 1. This cycle is repeated to achieve automated loading and unloading, greatly improving work efficiency without requiring machine downtime. Through the setting of the isolation component 3, when the shot blasting machine 1 is ready to perform shot blasting on the crankshafts, the control cabinet 5 will automatically control the machine to start the process. When cylinder 32 is started, its output end pushes push plate 33 to move. Push plate 33 drives isolation plate 34 to seal the inlet and outlet of shot blasting machine 1, preventing debris or shot blasting generated during the shot blasting process from splashing out and causing injury to operators, thus improving safety. After shot blasting is completed, control cabinet 5 automatically starts cylinder 32 again. The output end of cylinder 32 pulls push plate 33 to move in the opposite direction. Push plate 33 drives isolation plate 34 to open the inlet and outlet of shot blasting machine 1, facilitating the entry and exit of crankshaft, achieving the purpose of automated isolation, and further improving work efficiency and safety.

[0025] In summary, this utility model provides an automatic crankshaft shot blasting machine with automatic feeding and unloading. Through the conveying mechanism 2, the crankshaft only needs to be placed on the conveyor belt 24. The conveying mechanism 2 automatically transports the crankshaft into the shot blasting machine 1 for shot blasting and automatically transports it out of the machine after processing. No manual feeding or unloading is required, greatly improving work efficiency and reducing labor intensity. Furthermore, the perforated turning belt 26 allows the crankshaft to tumble during shot blasting, ensuring all-around shot blasting and avoiding dead zones, thus improving the uniformity and efficiency of the process. The number of crankshafts processed at one time can be set via the control cabinet 5, resulting in a high degree of automation. In addition, the conveyor belt 24 is suitable for crankshafts of different sizes, increasing the equipment's applicability and flexibility.
