Description

Technical Field

[0001] This utility model relates to the field of feeding technology for CNC machining centers, specifically a feeding device for CNC machining centers. Background Technology

[0002] When placing heavy workpieces into a machining center, the current practice is to use forklifts. Forklifts lift the workpieces using straps or forks and transfer them to the machining table inside the machining center. However, due to the large range of motion of the forklift forks, placing workpieces into the machining center using forklifts is difficult. Furthermore, the limitations of the forks prevent precise adjustments to the workpiece's position during placement, requiring further adjustments by operators. This results in low workpiece loading efficiency and affects processing efficiency. Utility Model Content

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0017] like Figure 1-5 As shown, a feeding device for a CNC machining center includes: The mounting bracket includes a first support part 1 and a second support part 2, which are arranged vertically. The translation part is mounted on the first support part 1 on the mounting frame and is capable of moving on the first support part 1. The winding section is located on the translation section. The output end of the winding section is equipped with a manual permanent magnet chuck 3, which can drive the permanent magnet chuck 3 to move up and down.

[0018] Furthermore, both the first support part 1 and the second support part 2 are made of profiles, and a placement platform 4 is provided at the bottom of the junction of the first support part 1 and the second support part 2.

[0019] The workpieces that can be transferred by this type of feeding device need to be magnetically attracted by the permanent magnet chuck 3. The permanent magnet chuck 3 has a handle to control its magnetic force switch. By turning the handle, the permanent magnet chuck 3 can have the ability to magnetically attract workpieces and lose the ability to magnetically attract workpieces. Since the weight of the workpieces transferred into the machining center 5 through this feeding device is generally heavy, the magnetic force that the permanent magnet chuck 3 can provide is at least enough to stably attract workpieces weighing 150kg. The permanent magnet chuck 3 with appropriate attraction force can also be selected according to actual needs.

[0020] Before the workpiece is attracted by the permanent magnet chuck 3, it needs to be transferred to the placement table 4. After the workpiece is placed on the placement table 4, it can be attracted by the permanent magnet chuck 3.

[0021] Furthermore, the translation part includes a mounting frame 6, which is slidably connected to the first support part 1. A fixed seat 7 is provided inside the mounting frame 6. A lead screw 8 is provided between the first support part 1 and the second support part 2. The lead screw 8 is threadedly connected to the fixed seat 7. A motor 9 for driving the lead screw 8 to rotate is provided on the first support part 1.

[0022] Furthermore, a partition 10 is provided inside the mounting frame 6 to improve the stability of the mounting frame 6.

[0023] Furthermore, the inner surface of the mounting frame 6 is provided with a through groove 11, and a fixed pulley 12 is provided inside the mounting frame 6 and on one side of the through groove 11. A winding wheel 13 is provided inside the mounting frame 6, and a motor 14 for driving the winding wheel 13 to rotate is provided inside the mounting frame 6. It also includes a rope 15, one end of which is connected to the permanent magnet chuck 3, and the other end of which passes around the fixed pulley 12 and is wound and fixed on the winding wheel 13. A through hole is provided on the partition plate 10 for the rope 15 to pass through.

[0024] After the workpiece is attracted by the permanent magnet chuck 3, in order to transfer the workpiece to the machining table inside the machining center 5, First, motor 14 needs to be started. Motor 14 drives the winding wheel 13 to rotate, and winds the rope 15 through the fixed pulley 12, raising the height of the permanent magnet chuck 3 and the workpiece. When the height of the workpiece is higher than the height of the machining table inside the machining center 5, motor 14 stops. Motor 14 has a reducer and a brake to ensure stable winding of the rope 15. At the same time, when winding the rope 15 stops, the brake can also suspend the workpiece in the air. After the workpiece is suspended in the air, motor 9 is started, and motor 9 drives the lead screw 8 to rotate. Then, the threaded connection between the lead screw 8 and the fixed seat 7, and the sliding connection between the mounting frame 6 and the first support part 1, allow the fixed seat 7 and the mounting frame 6 to move linearly along the lead screw 8, so that the front end of the mounting frame 6 and the workpiece below it can enter the machining center 5. After the workpiece moves to the top of the machining table, the placement position of the workpiece can be controlled by controlling the unwinding of the rope 15. After the workpiece is completely placed on the machining table, the permanent magnet chuck 3 can be separated from the workpiece by rotating the handle on the permanent magnet chuck 3, and then the mounting frame 6 can be removed from the machining center 5.

[0025] Motor 1 (9) and Motor 2 (14) can be controlled by a handheld controller. Signals can be transmitted via signal lines, Bluetooth, or a local area network. The handheld controller allows for convenient control of the start and stop of Motor 1 (9) and Motor 2 (14), thereby facilitating the control of the workpiece's movement position and lifting.

[0026] Two limit switches can be installed on the first support part 1, respectively set at the two limits of the movement range of the fixed base 7, to improve the safety of using the feeding device.

[0027] The rope 15 can be a metal chain or a nylon belt, and it needs to be able to withstand a large weight without severe deformation. When bearing a weight of 150kg, the deformation per meter of the rope 15 should not exceed 2%.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
