Description

Technical Field

[0001] The present invention belongs to the technical field of machining equipment, and particularly relates to a double-station cyclic machining device and a cutting machine using this device. Background Art

[0002] In the current booming modern manufacturing industry, the requirements for production efficiency, product quality, and production cost control are becoming increasingly stringent, which makes the application of automated machining equipment in industrial production crucial. Especially in the field of machining processes such as plasma arc cutting, how to achieve efficient, precise, and stable production has become a key problem that urgently needs to be solved.

[0003] Most traditional machining equipment adopts a single-station machining mode. In this mode, when the equipment is performing machining operations, it is impossible to perform the loading and unloading of workpieces simultaneously. For example, when a workpiece is being subjected to plasma arc cutting, it is necessary to wait until the workpiece is processed and removed before a new workpiece can be loaded and processed. This results in the equipment being idle during the period of loading and unloading workpieces, greatly reducing the effective operating time of the equipment, and severely restricting the overall production efficiency, making it difficult to meet the market demand for large-scale and high-efficiency production.

[0004] In addition, existing single-station machining equipment usually lacks an effective cyclic machining mechanism. When faced with the machining tasks of a large number of identical or similar workpieces, a series of operations such as loading and unloading, positioning, and machining need to be continuously repeated, which not only increases the labor intensity of operators but also easily causes operation errors due to human factors, thereby affecting the stability of product quality.

[0005] In terms of the clamping and positioning of workpieces, traditional equipment also has many deficiencies. For some workpieces with complex shapes and high dimensional accuracy requirements, existing clamping methods are difficult to provide sufficient stability and precise positioning. Taking plasma arc cutting as an example, if the workpiece undergoes a slight displacement or vibration during the cutting process, it may cause the cutting path to deviate, resulting in frequent problems such as uneven cutting surfaces and dimensional deviations, seriously affecting the qualification rate and machining quality of products.

[0006] In the material conveying link, traditional conveying devices often cannot be seamlessly connected with machining equipment. The conveying speed, conveying accuracy, and stability during the conveying process of materials are difficult to meet the requirements of efficient machining. For example, during the conveying process, materials may experience jams, collisions, etc., resulting in damage to the surface of workpieces and even affecting the normal operation of the entire production line. Moreover, existing material conveying devices lack sufficient flexibility and versatility when dealing with workpieces of different specifications and shapes, and frequently require adjusting equipment parameters or replacing conveying components, increasing production costs and the difficulty of equipment maintenance.

[0018] Beneficial effects: The invention has reasonable design, simple and stable structure, strong practicability, and has the following beneficial effects:

[0019] 1. The core design of the double-station cycle processing device is the coordinated operation of the hollow rotating platform, the follower frame and the clamping device. During the processing, when the workpiece on one clamping device is in the processing state, the other clamping device can perform loading and unloading operations simultaneously. This parallel working mode greatly reduces the idle time of the equipment due to loading and unloading workpieces. Compared with traditional single-station processing equipment, it can complete the processing of more workpieces in the same time, effectively improve the equipment utilization rate, and can fully meet the actual needs of large-scale production;

[0020] 2. The first clamping assembly of the clamping device is exquisitely designed. The L-shaped plate cooperates with the first guide groove on the connecting plate through the first slider on the outer wall to ensure stability and accuracy when adjusting the clamping position. The first cylinder drives the first clamping plate to cooperate with the first clamping block on the inner side of the L-shaped plate and the second clamping block on the first clamping plate. It can be flexibly and firmly clamped according to the shape and size of the workpiece. Whether it is a workpiece of regular shape or special shape, it can ensure that there is no displacement or shaking during the processing, thereby significantly improving the processing accuracy and stability;

[0021] 3. The loading and unloading device realizes the precise lifting and lowering of the lifting plate through the first driving component. The transmission of the first screw and the ball nut, as well as the cooperation of the guide rod and the linear bearing, make the lifting plate move smoothly and accurately in the vertical direction. The second clamping component adopts a bidirectional cylinder to drive the second clamping plate, which can quickly and accurately grab and place the workpiece. At the same time, the concave design of the lifting plate and the layout of the second clamping component enable it to better adapt to the loading and unloading needs of workpieces of different shapes, and closely cooperate with the double-station cycle processing mode, greatly improving the loading and unloading efficiency;

[0022] 4. The rotating shaft of the material conveying device is rotated by the second driving assembly. The meshing transmission of the worm and the worm gear and the cooperation of the gear parts ensure the stability of the rotating shaft rotation and the reliability of the power transmission. The rollers in the guiding assembly can reduce the friction of the material during the conveying process, enabling the material to move smoothly. The positioning plate positions the first frame and the second frame, thereby playing a role in limiting the workpiece, ensuring the position accuracy of the material during the conveying process. The setting of the limiting block effectively prevents excessive material conveying and avoids problems such as material accumulation or dropping, comprehensively ensuring the stability and accuracy of material conveying;

[0023] 5. The frame structure of the follower frame is solid. The combined design of the chassis and the side frame provides stable support. The protective shell can not only protect key components inside, such as the clamping device and the motor, from the influence of the external environment, such as dust and debris, but also play a role in sound insulation and heat insulation to a certain extent. It not only extends the service life of the equipment but also reduces the interference of external factors on the processing process, ensuring that the equipment always maintains a stable and reliable working state during long-term operation;

[0024] 6. The X-axis translation module, Y-axis translation module, and Z-axis translation module equipped on the cutting machine enable the cutting head to move precisely in three main dimensions to achieve processing of different positions of the workpiece. The axial rotation module and the rotation module endow the cutting head with the ability to rotate, enabling it to cut the workpiece from different angles. This multi-axis linkage design can meet the processing requirements of various complex-shaped workpieces, greatly improving the cutting accuracy and cutting quality, and broadening the application range of the equipment;

[0025] 7. The design of each device component fully considers the processing requirements of workpieces of different specifications. For example, the transmission method of the ball nut in the first driving assembly and the cooperation of the guiding rod and the linear bearing can adjust the stroke and speed of the lifting plate according to actual needs to adapt to the loading and unloading operations of workpieces of different heights. The first frame and the second frame of the guiding assembly can be adjusted in position through the meshing transmission of the third gear and the rack to adapt to the conveying requirements of workpieces of different widths. This flexible design enables the equipment to adapt to the processing, conveying, loading, and unloading operations of workpieces of various specifications, enhancing the versatility and adaptability of the equipment;

[0026] 8. The modular design of each component of the equipment, such as the clamping device, the loading and unloading device, the material conveying device, etc., facilitates quick disassembly and replacement when a certain component fails. At the same time, the structural design of each device is reasonable, and the key parts are easy to inspect and maintain, reducing the maintenance time and labor costs.
