Description

Technical Field

[0001] This utility model relates to the field of CNC machine tools, and in particular to a machine tool auxiliary feeding device. Background Art

[0002] In the field of modern mechanical manufacturing, CNC machines, as highly efficient and precise machining equipment, are widely used in the processing of various workpieces. To ensure machining accuracy and efficiency, the workpiece must be accurately fed into the machine tool's fixture and fixed, and then the cutting tool performs the predetermined cutting or shaping operation.

[0003] However, in actual production, the loading process often relies on manual operation, especially when handling heavy or bulky workpieces. This step becomes a significant bottleneck restricting production efficiency and safety. Traditional manual loading methods not only increase the labor intensity of operators, leading to low work efficiency, but also pose high safety risks during handling, such as accidental slippage of workpieces potentially causing equipment damage or personnel injury. Furthermore, frequent manual intervention can affect processing consistency and product quality. Utility Model Content

[0004] In order to improve the quality and efficiency of laser marking, this utility model provides a machine tool auxiliary feeding device.

[0005] The auxiliary feeding device for machine tools provided by this utility model adopts the following technical solution:

[0006] A machine tool auxiliary loading device includes a loading platform and a workpiece docking platform. The loading platform is a liftable structure with a sliding groove. The workpiece docking platform is disposed in the sliding groove and can slide within it. One end of the workpiece docking platform can extend out of the loading platform. A first guide roller is provided on the loading platform, with its axis parallel to the moving direction of the workpiece docking platform. A second guide roller is provided on the workpiece docking platform, with its axis perpendicular to the axis of the first guide roller.

[0007] The above technical solution, by designing the loading platform as a liftable structure and incorporating a chute on it, allows the workpiece docking platform to slide within the chute and extend out of the loading platform, thereby achieving automatic workpiece positioning and conveying. This significantly improves the accuracy and efficiency of workpiece loading, reduces manual intervention, lowers the operator's workload, and avoids safety hazards caused by improper manual handling. Furthermore, the placement of the first and second guide rollers ensures the stability and accuracy of the workpiece during conveying, preventing workpiece deviation or jamming during movement.

[0008] As a preferred embodiment of this utility model, a workpiece clamping mechanism is provided on the workpiece docking platform. The workpiece clamping mechanism includes a cylinder and a pressure plate, and the piston rod of the cylinder is connected to the pressure plate through a connecting rod.

[0009] The above technical solution effectively fixes the workpiece on the workpiece docking platform by connecting the piston rod of the cylinder to the pressure plate. This design not only ensures the stability of the workpiece during transportation and prevents displacement during movement, but also improves the positioning accuracy of the workpiece, ensuring the accuracy of subsequent processing.

[0010] As a preferred embodiment of this invention, the pressure plate and the connecting rod form a detachable structure.

[0011] The detachable structure between the pressure plate and the connecting rod, achieved through the aforementioned technical solution, allows for rapid replacement of the pressure plate according to the size and shape of different workpieces, improving the flexibility and adaptability of the device. This not only simplifies the operation process and shortens changeover time but also reduces maintenance costs. In actual production, different workpieces vary significantly in size and shape; the detachable pressure plate design allows for quick adjustment to meet the needs of different workpieces, improving the versatility and production efficiency of the device.

[0012] As a preferred embodiment of this utility model, a guide groove is further provided at the bottom of the chute, a guide block is provided at the bottom of the workpiece docking platform, the guide block is provided in the guide groove, a lead screw is also provided in the guide groove, the lead screw is connected to the guide block, and the lead screw is also connected to a drive motor provided on the loading platform.

[0013] The above technical solution ensures the precise movement of the workpiece docking table within the chute, improving the stability and accuracy of workpiece conveying. By controlling the rotation of the lead screw with a drive motor, automated movement of the workpiece docking table is achieved, reducing manual operation errors and increasing production efficiency. Furthermore, the combined use of guide grooves and guide blocks effectively prevents the workpiece docking table from shifting during movement, ensuring precise workpiece positioning.

[0014] As a preferred embodiment of this invention, it also includes a base, which is connected to the loading platform via a fork and a hydraulic cylinder.

[0015] The above technical solution connects the base and the loading platform via a fork and hydraulic cylinder, enabling the loading platform to move vertically. The extension and retraction of the hydraulic cylinder allows for flexible adjustment of the loading platform's height to accommodate machine tools and workpieces of varying heights. This not only expands the device's applicability but also ensures stable workpiece transport at different heights, preventing workpiece damage or processing errors caused by height mismatches. Furthermore, the use of the fork increases the device's structural strength, improving overall stability and reliability.

[0016] As a preferred embodiment of this invention, a caster wheel is also provided on the base.

[0017] By incorporating casters into the base, the entire device can be easily moved to different work positions, improving its flexibility and portability. It is suitable for production environments requiring frequent changes in processing positions, allowing for rapid repositioning and saving transportation time and labor.

[0018] As a preferred embodiment of this invention, a storage battery and a handle are also provided on the base.

[0019] By incorporating a battery and handle into the base, the device can operate independently without an external power source, enhancing its autonomy and convenience. Especially in situations without a fixed power source, such as temporary processing sites or outdoor operations, battery power ensures normal operation, freeing it from power limitations. The handle design facilitates maneuvering, improving operability and portability. This not only simplifies the device's use but also expands its application range, making it more suitable for various production environments.

[0020] As a preferred embodiment of this utility model, the workpiece docking platform is located in the middle of the loading platform, and first guide rollers are provided on both sides of the loading platform of the workpiece docking platform.

[0021] By placing the workpiece docking platform in the center of the loading platform using the above technical solution, workpieces can approach the platform evenly from both sides. Regardless of whether the workpiece enters from the left or right, it can be easily aligned with the docking platform, reducing adjustment time and difficulty during loading. Secondly, this layout optimizes space utilization, making the space on both sides of the loading platform more symmetrical, facilitating operation from different directions and improving operational flexibility and comfort. Furthermore, the central position of the workpiece docking platform better balances the load distribution on the loading platform, reducing structural deformation and damage caused by uneven loading, and improving the stability and durability of the device.

[0022] In summary, this utility model has at least one of the following beneficial technical effects:

[0023] This utility model's machine tool auxiliary feeding device designs the feeding platform as a liftable structure and sets up a sliding groove on the feeding platform, allowing the workpiece docking table to slide within the groove and extend out of the feeding platform, thereby achieving automatic workpiece positioning and conveying. This significantly improves the accuracy and efficiency of workpiece feeding. Compared to traditional manual feeding, it not only reduces manual intervention and the operator's workload but also avoids safety hazards caused by improper manual handling.
