Description

Technical Field

[0001] The utility model relates to a double-servo receiving device for die-casting parts. Background Art

[0002] With the increasing degree of industrial automation, automated production has been achieved in many industries, especially the die-casting industry. In the die-casting industry, the grasping of die-cast parts is often accomplished using an automated material-retrieving mechanical gripper. For example, the automatic material-retrieving mechanical arm for die-casting, published as CN212218472U, includes a cross plate, a support rod, a hinge, a clamping block, a fixed block, a connecting block, a sleeve, an inner rod, a limit block, a clamping strip, a first motor, a base, a rotating block, a fixed rod, a rotating shaft, a coupling, a finger cylinder, a collet, an infrared sensor, a second motor, a hydraulic push rod, and a third motor. The overall design of the retrieving robot arm is reasonable. The bottom of the entire robot arm is fixed by a clamping bar and a fixing bolt. The first motor drives the fixed rod and the support rod to rotate, which is convenient for adjusting the retrieving direction of the entire robot arm. The rotation of the third motor can adjust the tilt angle of the support rod and change the height of the crossbar and the claw. At the same time, the angle between the cross plate and the support rod is adjusted by a hinge, and then the clamping block is fixed. The infrared sensor detects the distance to the die-casting part. The hydraulic push rod drives the coupling downward to use the claw to grasp the die-casting part. The grasping angle of the claw can be adjusted by the second motor, which has achieved the effect of convenient use. However, the retrieving robot arm has only one mechanical claw. Die-cast products are often diverse. When a die-casting machine produces multiple different types of products, the mechanical claw can only grasp one type of die-casting part. If you want to grasp other die-casting parts, you need to replace the corresponding mechanical claw, which is very inconvenient, time-consuming and labor-intensive, and costly. Utility Model Content

Two connecting blocks 44 are symmetrically installed at the left and right ends of the rotating rod 43, and a receiving tray 5 is fixedly installed on the two connecting blocks 44. Three supporting blocks 45 are fixedly installed at the rear end of the second movable frame 32, one of the supporting blocks 45 is installed at the end of the rear end of the second movable frame 32, and the two supporting blocks 45 are symmetrically installed on the left and right sides of the rear end of the second movable frame 32 to support the receiving tray 5 so that it can maintain a horizontal state. It should be noted that the support blocks 45 have no connection relationship with the receiving tray 5, so that the receiving tray 5 can be flipped outward along the rotating rod 43 to pour out different types of die-castings received in the receiving tray 5 onto the conveyor belt.

[0034] Furthermore, a first fixing frame 6 is provided on the inner side of the frame 1 , and two support rods 7 are symmetrically provided on the first fixing frame 6 .

[0035] In this embodiment, a first fixed frame 6 is fixedly installed on the inner side of the frame 1, and two support rods 7 are symmetrically installed on the first fixed frame 6. When the first servo motor 24 drives the first movable frame 22 to move downward, the support rod 7 can pass through the first movable frame 22, the support frame 23 and the second movable frame 32, and contact the bottom of the receiving tray 5 until the receiving tray 5 is lifted up and tilted outward along the rotating rod 43, so as to facilitate pouring different types of die-castings received in the receiving tray 5 onto the conveyor belt.

[0036] Furthermore, a second fixing frame 8 is provided on the outer side of the frame 1 , and a buffer 9 is provided on the second fixing frame 8 .

[0039] In this embodiment, first limit switches 10 are installed on the left and right sides of the first linear guide pair 21, that is, on the frames 1 on the left and right sides of the first linear guide, to limit the up and down movement distance of the first movable frame 22, thereby ensuring the safe operation of the device. Second limit switches 11 are installed on the left and right sides of the second linear guide pair 31, that is, on the support frames 23 on the left and right sides of the second linear guide, to limit the left and right movement distance of the second movable frame 32, thereby further ensuring the safe operation of the device.

[0040] Furthermore, a drag chain 12 is provided on the rack 1 .

[0041] In this embodiment, a drag chain 12 is installed on the front side of the frame 1, and the connected lines can be passed through the drag chain 12 to prevent the lines from being excessively bent and damaged during the operation of the device, thereby providing certain protection for the connected lines.

[0042] During use, after the hydraulic press completes trimming of the die-cast product, the die-cast product will remain on the trimming die. At this time, the first servo motor 24 is controlled to drive the first movable frame 22 to move upward along the frame 1 on the first linear guide pair 21, until the first movable frame 22 drives the receiving tray 5 to rise to a height matching the trimming die. Then the second servo motor 34 is controlled to drive the screw rod pair 33 to drive the second movable frame 32 to move on the second linear guide pair 31. The second movable frame 32 drives the receiving tray 5 to extend into the interior of the hydraulic press. At this time, the trimming die releases the die-cast product, and the die-cast product falls into the receiving tray 5. Then the second servo motor 34 is controlled to drive the screw rod pair 33 to drive the second movable frame 32 to move on the second linear guide pair 31. The second servo motor 34 drives the threaded screw pair 33 to drive the second movable frame 32 to move in the opposite direction to the initial position on the second linear guide pair 31, and finally controls the first servo motor 24 to drive the first movable frame 22 to move downward along the frame 1 on the first linear guide pair 21. The bottom of the receiving tray 5 contacts the support rod 7 and lifts the receiving tray 5, so that the receiving tray 5 is flipped and tilted outward along the rotating rod 43, and the die-cast products automatically slide onto the product conveyor belt, thereby realizing the reception of different types of die-cast products. There is no need to replace the mechanical claws due to the different types of die-cast products received, which saves time and effort and reduces production costs.
