[0048] The utility model discloses a device for automatically clamping and expanding holes of a material.

[0049] like Figure 1 , Figure 2 , Figure 3 As shown, an embodiment of the utility model provides an automatic clamping and reaming device for a material, specifically, an automatic clamping and reaming device for a hinge plate, including a feeding unit, a processing unit, and a discharging unit.

[0050] Among them, the feeding unit includes a material box 21, a material pushing double-axis cylinder 22, a horizontal material feeding double-axis cylinder 31, a material lifting double-axis cylinder 32, and an electromagnetic suction cup 33. The material box 21 is used to accommodate the hinge plate 11 to be processed. The material pushing double-axis cylinder 22 is connected to the material box 21, and is used to push the hinge plate in the material box 21 to a specified position. The horizontal material feeding double-axis cylinder 31 is connected to the electromagnetic suction cup 33 to control the movement of the electromagnetic suction cup 33 in the horizontal direction. The material lifting double-axis cylinder 32 is connected to the electromagnetic suction cup 33 to control the movement of the electromagnetic suction cup 33 in the vertical direction. The electromagnetic suction cup 33 controls the suction and drop of the hinge plate 1 through magnetic force. The feeding unit transfers the hinge plate 1 to the processing unit.

[0051] The processing unit includes a hollow rotating table 411, a hollow rotating table driving motor 412, a material fixture 42, a material pressing cylinder 441, a material pressing device 442, a processing tool 45, a Z-axis linear guide 461, a Z-axis servo motor 462, a roller screw 48, an X-axis servo motor 491, and an X-axis linear guide 492. A compressed air inlet 413 is provided at the center of the hollow rotating table 411, and a compressed air inlet pipe is provided in the compressed air inlet 413 for inputting compressed air into the material pressing cylinder 441. The hollow rotating table driving motor 412 drives the hollow rotating table 411 to rotate. The material fixture 42, the material pressing cylinder 441, and the material pressing device 442 are all arranged on the hollow rotating table 411. The material fixture 42 is used to place the hinge plate to be processed. A positioning pin (not shown in the figure) is arranged in the center of the material fixture 42, and positioning guide plates 43 are arranged on both sides to realize the positioning of the hinge plate 1. The pressing cylinder 441 drives the pressing device 442 to clamp and fix the hinge plate 1 placed on the material fixture 42. The processing tool 45, the Z-axis linear guide 461, the Z-axis servo motor 462, the roller screw 48, the X-axis servo motor 491, the X-axis linear guide 492, etc. are all arranged on the tool holder column 47. The processing tool 45 realizes the cutting and expanding of the hinge plate 1. The Z-axis servo motor 462 drives the roller screw 48 to make the processing tool 45 move in the vertical direction of the Z axis along the Z-axis linear guide 461. The X-axis servo motor 491 drives the roller screw 48 to make the processing tool 45 move in the horizontal direction along the X-axis linear guide 492. The roller screw 48 is connected to the X-axis bearing seat 493. The processing unit realizes the cutting and expanding processing of the hinge plate.

[0052] The discharging unit includes a discharging trough 5. Driven by the horizontal feeding double-axis cylinder 31 and the material lifting double-axis cylinder 32, the electromagnetic suction cup 33 transfers the processed hinge plate to the discharging trough 5 to complete the discharging.

[0053] The hinge plate automatic clamping and hole enlarging device further comprises a workbench 71 and a frame 72. The feeding unit, the processing unit and the discharging unit are all arranged on the workbench 71, and the frame 72 provides fixed support for the workbench 71.

[0054] The specific implementation scheme of the automatic clamping and reaming device for medium-sized parts of the utility model is as follows:

[0055] like Figure 1 , Figure 2 , Figure 3As shown, an embodiment of the utility model provides an automatic clamping and reaming device for materials, wherein, during the operation of the device, the compressed air source is first turned on and the power supply of the electrical control box 6 is turned on, and various external sensors, CNC servo controllers, etc. are automatically scanned and detected to confirm whether the relevant components have faults. After the detection shows that there is no fault, the worker puts a certain number of hinge plates to be processed into the material box 21 in sequence, and turns on the automatic processing button on the electrical control box 6. Then, after the position sensor (not shown in the figure) in the feeding unit detects that the hinge plate 1 has been placed in the correct position in the material box 21, the material lifting double-axis cylinder 32 drives the electromagnetic suction cup 33 to descend to the set position, the electromagnetic suction cup 33 is energized and uses magnetic force to suck the hinge plate to be processed, and then the material lifting double-axis cylinder 32 drives the electromagnetic suction cup 33 to rise to the set height, and then the horizontal feeding double-axis cylinder 31 drives the electromagnetic suction cup 33 to move horizontally to the set position above the hollow rotating worktable 411. After the electromagnetic chuck 33 reaches the correct position above the hollow rotating worktable 411, the material lifting dual-axis cylinder 32 drives the electromagnetic chuck 33 to descend. After the sensor (not shown in the figure) arranged below the material lifting dual-axis cylinder 32 sends a signal to detect that the electromagnetic chuck 33 has descended to the set position, the electromagnetic chuck 33 is powered off, the magnetic force disappears, and the hinge plate 1 is placed in the material fixture 42. A positioning pin is arranged at the center of the material fixture 42, and positioning guide plates 43 are arranged on both sides to position the placed hinge plate 1. Then, the material lifting dual-axis cylinder 32 drives the electromagnetic chuck 33 to rise to the initial height, and the horizontal feeding dual-axis cylinder 31 drives the electromagnetic chuck 33 to move horizontally back to the initial position. At the same time, the pushing dual-axis cylinder 22 pushes another hinge plate to be processed to the bottom of the electromagnetic chuck 33.

[0056] After the hinge plate to be processed is transferred to the material fixture 42, the press cylinder 441 drives the press device 442 to clamp the hinge plate 1, and then the Z-axis servo motor 462 drives the roller screw 48 to make the processing tool 45 descend along the Z-axis linear guide 461, and when the processing tool 45 starts to descend, the hollow rotary table drives the motor 412 to start synchronously, driving the hollow rotary table 411 to rotate. After the processing tool 45 descends to the set height and contacts the hinge plate 1 to cut into the set depth, the X-axis servo motor 491 starts to drive the roller screw 48, so that the processing tool 45 moves in the horizontal direction along the X-axis linear guide 492 to perform cutting and expanding processing on the hinge plate 1. After the cutting and expanding processing is completed, the hollow rotary table drives the motor 412 to stop working, and the hollow rotary table 411 stops rotating and returns to the initial position and direction. At this time, the press cylinder 441 drives the press device 442 to relax and release the fixation of the hinge plate 1. Then, the electromagnetic chuck 33 is driven by the horizontal feeding double-axis cylinder 31 and the material lifting double-axis cylinder 32 in sequence, and the hinge plate 1 is taken out of the material clamp 42 by magnetic force. During the retraction process of the electromagnetic chuck 33, the electromagnetic chuck 33 is powered off and releases the magnetic force at the set position, so that the hinge plate 1 falls into the discharge chute 5, and the discharge is completed.

[0057] The utility model has the advantages of saving a lot of manpower, greatly reducing labor intensity and production costs; improving production and processing efficiency through automated settings; the processing accuracy is controlled by the machine, the product quality is stable, and the scrap rate is low.
