Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 5 The utility model provides a technical solution: a heart-shaped clamp picking device, a track frame 1, characterized in that: the track frame 1 is installed with a lead screw 2 through the servo motor output end opened on the outside thereof, the lead screw 2 is connected to a first cylinder 3 through a nut opened on the surface thereof by bolts, the bottom of the first cylinder 3 is connected to one end of a connecting frame 4 by bolts, the other end of the connecting frame 4 is connected to a clamp bracket 5 by bolts, a cleaning piece 6 is opened below one side of the clamp bracket 5, and the clamp bracket 5 is connected to a clamping piece 8 through a pneumatic component 7 opened inside thereof.

[0024] The pneumatic assembly 7 includes a second cylinder 701, a rack 702 and a gear 703. The top of the rack 702 is welded to one end of the second cylinder 701. The gear 703 is respectively meshed and connected to the two ends of the rack 702. The gears 703 are respectively rotatably connected to the inside of the clamp bracket 5. The gear 703 is rotatably connected to the first connecting rod 704 through a connecting pin. The first connecting rod 704 is rotatably connected to the two ends of the outside of the clamp bracket 5. A second connecting rod 705 is opened between the first connecting rods 704. The second connecting rod 705 is a symmetrical part and one end is rotatably connected to the bottom wall of the outside of the clamp bracket 5. The other end of the second connecting rod 705 is connected to the clamping member 8 through a connecting pin.

[0025] In this embodiment, Figure 1 and Figure 2 As shown, the clamp bracket 5 forms a lifting structure through the first cylinder 3, and the first cylinder 3 forms a transmission structure on the surface of the track frame 1 through the screw 2; the structure for grasping the workpiece is combined with the structure of the first cylinder 3 and the track frame 1, which is convenient for the transportation of the workpiece. After the workpiece is grasped, the first cylinder 3 can drive the workpiece to rise and transmit it to the next processing point through the track frame 1, effectively avoiding the tediousness of manual picking.

[0026] In this embodiment, Figure 3 , Figure 4 and Figure 5 As shown, the rack 702 is slidably connected to the inner wall of the clamp bracket 5 through the second cylinder 701 to form a lifting structure, and the gear 703 forms a transmission structure through the rack 702, and the gears 703 move relative to each other; by adding the structure of the rack 702 and the gear 703, compared with directly driving the clamp through the second cylinder 701, the meshing structure can better convert the power of the second cylinder 701 into an effective gripping action, and can better control the gripping force of the bottom clamp 8, making it more accurate when gripping objects.

[0027] In this embodiment, Figure 3 , Figure 4 and Figure 5 As shown, the first connecting rods 704 are relatively distributed, and one end of the first connecting rod 704 is connected to the clamping member 8 through a connecting pin, and the first connecting rod 704 and the second connecting rod 705 are connected through a compression spring 706, and the first connecting rod 704 and the second connecting rod 705 form an opening and closing structure through a gear 703; the compression spring 706 between the first connecting rod 704 and the second connecting rod 705 provides effective support for the grasping of the bottom workpiece, so as to ensure that no excessive torque or unbalanced force transfer occurs during operation, thereby maintaining the stability and reliability of the workpiece grasping.

[0028] In this embodiment, Figure 3 , Figure 4 and Figure 6As shown, the clamping members 8 move relative to each other through the first connecting rod 704 and the second connecting rod 705, and the clamping members 8 form an opening and closing structure, and the clamping members 8 are heart-shaped when closed, and at the same time, the inner wall of the clamping member 8 is glued with a rubber friction-increasing pad 9; the transmission of the gear 703 can accurately control the running speed and force of the clamping member 8, so as to more accurately adjust the force and speed of grasping the object, and provide effective protection for aluminum alloy parts with complex shapes or thin walls, and can adapt to different workpieces and operation requirements, and the shape of the clamping member 8 can be surrounded in a surrounding manner, so that it can provide a more uniform pressure distribution when clamping the workpiece, which helps to reduce the probability of deformation of the workpiece surface, especially for aluminum alloy parts with complex shapes or thin walls. It is particularly important, and at the same time, it can adapt to aluminum alloy parts of different sizes and shapes. The external friction-increasing pad 9 increases the contact area between it and the workpiece, improves the friction coefficient, and ensures the stability of the workpiece during movement, and improves the versatility and flexibility of the clamp.

[0029] In this embodiment, Figure 1 As shown, the bottom of the cleaning piece 6 is provided with several cylindrical bodies with conical bottoms at equal distances; when the front end clamp is removed after clamping the workpiece, the several conical objects at the bottom of the cleaning piece 6 can correspondingly bring out the impurities generated during the die-casting process in the mold gap.

[0030] The use method and advantages of the utility model: When the heart-shaped clamp picking device is used, the working process is as follows:

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, first, the device can be connected between two devices to be connected by installing a track frame 1 and driving the lead screw 2 to rotate through a servo motor, so that the nut on the surface of the lead screw 2 drives the first cylinder 3 and the grabbing assembly below to move to the grabbing point, and the second cylinder 701 pushes the rack 702 to slide inside the fixture bracket 5. While the rack 702 descends, it engages with the gears 703 at both ends to form a transmission structure, thereby driving the first connecting rod 704 at both ends to open respectively. When the first connecting rod 704 opens, the second connecting rod 705 connected to it and the clamping member 8 below open at the same time. After docking with the workpiece, the second cylinder 701 is driven in the reverse direction to make the rack 702 rise, and the gear 703 at both ends of the rack 702 is engaged with the gears 703 at both ends to form a transmission structure. 03 While rotating in the opposite direction, the first connecting rod 704 and the second connecting rod 705 are retracted and the clamping member 8 is closed to cover the workpiece on the inner wall. If the clamped workpiece is too heavy, the workpiece is directly dragged from the processing table to the next processing point through the transmission structure of the screw 2. If the workpiece is small and light, the clamp bracket 5 that has clamped the workpiece can be driven to rise through the first cylinder 3, and then transmitted to the next processing point through the transmission structure. The equipment transports the grasped workpiece between equipment through the transmission structure, reducing the tediousness of manual transportation, and during the clamping movement of the front end clamping member of the clamp bracket 5, the cleaning member 6 at the bottom can correspondingly bring out impurities generated during the die-casting process in the mold gap.

Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
