Description

Technical Field

[0001] This utility model relates to the field of palletizing machine technology, and in particular to a palletizing machine mechanism for loading and unloading machine tools. Background Technology

[0002] In the field of mechanical processing technology, machine tool processing is a common processing method. Machine tool processing requires mounting the workpiece onto the machine tool's worktable, waiting for the machine to process it, and then removing the processed workpiece from the worktable. Manual loading and unloading of workpieces is inconvenient, especially for large and heavy workpieces, where it is very costly and may even require multiple people to work together, resulting in high labor costs. Utility Model Content

[0003] In order to solve the above-mentioned problems in the prior art, this utility model provides a palletizing machine structure for loading and unloading machine tools that is easy to use, has a high load capacity, and greatly reduces labor costs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A palletizing machine structure for loading and unloading machine tools includes a ground rail and a base that can slide along the ground rail in the X direction. A frame is fixed on the base. A lifting seat that can slide in the Z direction is provided on the front side of the frame. A slide table that can slide in the Y direction is provided on the lifting seat. A connecting arm is provided on the slide table. The inner end of the connecting arm is rotatably connected to the slide table. A fork is rotatably provided on the outer end of the connecting arm. A first rotational power for driving the connecting arm to rotate is provided on the slide table. A second rotational power for driving the fork table to rotate is provided on the outer end of the connecting arm. A plurality of limiting pins for limiting the pallet are provided on the top surface of the fork table.

[0006] By adopting the above technical solution: when in use, this palletizer is installed between the machine tool and the silo. The fork can move in three directions (X, Y, and Z), and the angle of the fork can be adjusted by the first and second rotational forces. The fork has five degrees of freedom of movement, making its movement very flexible and better adaptable to loading and unloading of materials in the silo and machine tool. The fork directly picks up the pallet assembly with the workpiece and transfers the pallet assembly and workpiece together into the machine tool and connects to the machine tool's worktable. After the workpiece is processed, the pallet assembly and the processed workpiece are moved and transferred to the silo, thereby realizing rapid transfer of workpieces between the silo and the machine tool, greatly reducing labor costs.

[0007] Preferably, the ground rail has slide rails on both sides, the base is slidably connected to the slide rails, the ground rail has racks distributed parallel to the slide rails, and the base has a first motor with gears meshing with the racks. The first motor drives the gears to move along the racks, enabling switching between different machine tools.

[0008] Preferably, the bottom of the sliding seat is provided with a roller brush wheel and a grease injection pipe for supplying lubricating grease to the roller brush wheel. A rotary joint is provided between the roller brush wheel and the grease injection pipe, and the side of the roller brush wheel contacts the tooth surface of the rack. The grease injection pipe is connected to the roller brush wheel through the rotary joint, ensuring sufficient lubricating grease on the rack during movement, ensuring lubrication of the gear and rack, and reducing wear.

[0009] Preferably, sensors are installed at both ends of the ground rail, and sensing plates are installed on the sliding seat at corresponding positions to the sensors. When the sensor detects the sensing plate, the first motor stops moving. Anti-collision seats are installed at both ends of the ground rail, and shock-absorbing blocks are installed on the anti-collision seats. The sensing plates, in conjunction with the sensors, serve as safety limiters; when the sensors fail, the shock-absorbing blocks can further mitigate the impact force, thus providing overall safety protection.

[0010] Preferably, the frame is configured as a gantry frame, with a reinforcing frame between the rear of the frame and the base. The frame is equipped with a lifting mechanism for driving the Z-axis movement of the lifting seat. The lifting mechanism includes a vertically distributed Z-axis lead screw and a second motor that drives the Z-axis lead screw to rotate. A Z-axis lead screw seat is fixed to the lifting seat, and the Z-axis lead screw passes through the Z-axis lead screw seat to form a threaded connection. The gantry frame has high strength and good stability, and the reinforcing frame further increases the overall strength of the gantry frame. The rotation of the Z-axis lead screw driven by the second motor drives the Z-axis lifting seat to move in the Z-axis direction.

[0011] Preferably, the lifting base is equipped with a translation mechanism for driving the slide table to move in the Y direction. The translation mechanism includes a Y-axis lead screw and a third motor for driving the Y-axis lead screw to rotate. The slide sleeve is equipped with a Y-axis lead screw seat, and the Y-axis lead screw passes through the Y-axis lead screw seat to form a threaded connection. By driving the rotation of the Y-axis lead screw through the third motor, stable Y-axis translation of the slide sleeve is achieved.

[0012] Preferably, the rear side of the frame is provided with Z-axis distributed slide rods, and a counterweight is provided on the slide rods. The upper end of the frame is provided with a connecting seat, and a sprocket is provided on the connecting seat. A chain is provided on the counterweight, and the other end of the chain passes over the sprocket and connects to the lifting seat. The counterweight is slidably mounted on the slide rods, which plays a role in stabilizing the counterweight and reducing wear between the Z-axis lead screw and the Z-axis lead seat.

[0013] Preferably, the outer end of the fork is provided with a U-shaped groove, and the limiting pins are distributed along the edge of the U-shaped groove; the inner end of the top surface of the fork is provided with a card reader for reading the workpiece processing information corresponding to the pallet assembly. The U-shaped groove facilitates avoidance when inserting the pallet assembly, and the card reader is used to record the processing information of the corresponding workpiece on the chip on the pallet assembly, and to transfer the workpiece to the corresponding machine tool according to the workpiece processing information.

[0014] Therefore, this utility model has the beneficial effects of being easy to use, stable, heavy-duty, and greatly reducing labor costs. Attached Figure Description

[0025] The ground rail 1 has slide rails 11 on both sides, and the base 2 is slidably connected to the slide rails 11. The ground rail 1 has racks 12 distributed parallel to the slide rails 11. The base 2 has a first motor 212, and the first motor 212 has gears 213 that mesh with the racks 12. The bottom of the base 2 has a brush wheel 214 and a grease injection pipe 215 that provides lubricating grease to the brush wheel 214.

Sensors 13 are provided at both ends of the ground rail 1, and sensing plates 217 are provided on the base 2 at corresponding positions to the sensors 13. When the sensor 13 detects the sensing plate 217, the first motor 212 stops moving.

In some embodiments, sensor 13 is a proximity sensor or a proximity switch.

[0026] like Figure 3 and Figure 5 As shown, the frame 21 is configured as a gantry frame, and a reinforcing frame 211 is provided between the rear side of the frame 21 and the base 2. The frame 21 is provided with a lifting mechanism 221 for driving the lifting seat 22 to move in the Z direction. The lifting mechanism 221 includes a vertically distributed Z-direction screw 222 and a second motor 223 for driving the Z-direction screw 222 to rotate. A Z-direction screw seat is fixed on the lifting seat 22, and the Z-direction screw 222 passes through the Z-direction screw seat to form a threaded connection. The lifting seat 22 is provided with a translation mechanism 231 for driving the slide table 23 to move in the Y direction. The translation mechanism 231 includes a Y-direction screw 232 and a third motor 233 for driving the Y-direction screw 232 to rotate. A Y-direction screw seat is provided on the sliding sleeve, and the Y-direction screw 232 passes through the Y-direction screw seat to form a threaded connection.

[0027] The frame 21 has Z-shaped sliding rods 28 on its rear side, and a counterweight 281 on the sliding rods 28.

[0029] Referring to the accompanying drawings, the principle of this utility model is as follows: Figure 7 As shown, in use, the ground rail is set between the machine tool and the hopper 4. Multiple machine tools are located on one side of the ground rail, and the hopper 4 is on the other side. Multiple pallet assemblies 3 are installed in the hopper, each holding a workpiece to be processed. When the machine tool needs to load, the base moves along the X-axis, the lifting seat moves along the Z-axis, and the sliding sleeve moves along the Y-axis. The first and second rotational forces then drive the fork to move into the hopper and pick up a pallet assembly (the pallet assembly contains the workpiece to be processed, and a chip recording processing information is located on the side of the pallet assembly). The card reader reads the processing information from the chip and transfers the pallet assembly to the corresponding machine tool's worktable (an exchangeable worktable can be used, directly docking and locking with the pallet assembly). After the workpiece on the pallet assembly is processed by the machine tool, the fork directly transfers the pallet assembly and workpiece together into the hopper. Using this palletizer in conjunction with machine tool loading and unloading eliminates manual loading and unloading, greatly reducing labor costs.
