DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0029] like Figure 1 As shown, this embodiment provides a part grasping device, including a grasping unit 1 and a cooling unit 2; the grasping unit 1 includes two grasping clamps 11, a horizontal displacement mechanism 12 and a vertical displacement mechanism 13, the grasping clamp 11 is a double-layer structure including a grasping clamp inner wall 111 and a grasping clamp outer wall 112, an installation cavity 113 is arranged between the grasping clamp inner wall 111 and the grasping clamp outer wall 112, and the cooling unit 2 is arranged in the installation cavity 113.

[0030] The grabbing unit 1 of this embodiment takes grabbing plate-shaped parts as an example, and the two grabbers 11 of the grabbing unit 1 are arranged horizontally opposite to each other. The cross-section along the vertical direction is two "concave" shapes with openings opposite to each other. The area between the "concave"-shaped grabber inner wall 111 and the grabber outer wall 112 is the part grabbing area 114, and the grasped part is located in the part grabbing area 114. A plurality of grooves 115 are arranged on the upper and side surfaces of the grabber inner wall 111, and a U-shaped closed installation cavity 113 is provided between the two grabber inner walls 111 and the grabber outer wall 112 for installing the cooling unit 2.

[0031] The horizontal displacement mechanism 12 is located above the gripper 11, and includes a mounting frame 121, a bidirectional screw 122, a connecting rod 123, a motor 124, and a guide rod 125; the bidirectional screw 122 is horizontally arranged, and its two ends are rotatably connected to the mounting frame 121; the guide rod 125 is located below the bidirectional screw 122 and is horizontally arranged, and its two ends are fixedly connected to the mounting frame 121, and the surface of the guide rod 125 is smooth. The motor 124 is fixed on the mounting frame 121, and is connected to one end of the bidirectional screw 122 through a gear, and can drive the bidirectional screw 122 to rotate. The two connecting rods 123 are vertically arranged, one end of which is fixedly connected to the two grippers 11 respectively, and the other end is respectively sleeved on the two bidirectional screws 122 and the two guide rods 125. The two connecting rods 123 are threadedly connected to the bidirectional screw 122 and distributed on both sides of the bidirectional screw 122, and are respectively slidably connected to the guide rods 125.

[0032] When implementing the grasping task, the starting motor 124 drives the bidirectional screw 122 to rotate forward or reverse. The rotation of the bidirectional screw 122 drives the two connecting rods 123 to move. Since the connecting rods 123 are guided and restricted by the guide rods 125, the two connecting rods 123 can only approach or move away from each other in the horizontal direction, thereby making the grasping clamps 11 connected to them approach or move away from each other, thereby realizing the grasping or releasing action of the parts.

[0033] The vertical displacement mechanism 13 is located above the horizontal displacement mechanism 12 and is a hydraulic telescopic mechanism. The output end of the hydraulic telescopic mechanism is fixedly connected to the mounting frame 121 and can be used to drive the horizontal displacement mechanism 12 to move along the vertical direction together with the gripper 11. In some other embodiments, the vertical displacement mechanism 13 can also be replaced by other structures that can achieve vertical displacement.

[0034] like Figure 2As shown, the cooling unit 2 includes an air cooling component 21, and the air cooling component 21 includes an air inlet 211, an air outlet 212 and an air cooling channel 213. The two air inlets 211 are respectively located at the other end of the opening of the two grippers 11, and the two air inlets 211 are connected to the fan. The air outlet 212 is arranged in each groove 115, and the channel between the air inlet 211 and the air outlet 212 is the air cooling channel 213. The cold air generated by the fan enters the air cooling channel 213 from the air inlet 211, and then is ejected toward the part from the air outlet 212 to cool the gripping component of the part.

[0035] Furthermore, the cooling unit 2 also includes a water cooling component 22, which includes a water cooling pipe 221 and a coolant 222. The water cooling pipe 221 is built into the installation cavity 113 and is in close contact with the inner wall of the installation cavity 113. Both ends of the water cooling pipe 221 are located on the outer wall 112 of the gripper outside the installation cavity 113 and are connected to a water pump. The coolant 222 is located in the water cooling pipe 221. The coolant 222 circulates under the action of the water pump. When passing through the area where the installation cavity 113 is located, the installation cavity 113 can be cooled. The coolant 222 absorbs the heat of the installation cavity 113. After further heat exchange through the externally connected radiator, the temperature of the coolant 222 is reduced, thereby playing a role of circulating cooling. Since the cooling pipe 221 is in close contact with the inner wall of the installation cavity 113, the surface temperature of the installation cavity 113 can also be reduced. On the one hand, the temperature of the part gripping area 114 can be reduced, and at the same time, the bottom of the part it contacts can also be cooled.

[0036] It should be noted that, in the present embodiment, the cross-sections of the two installation cavities 113 are U-shaped with openings facing each other. In some other embodiments, installation cavities 113 with other shapes and structures may be selected according to the needs of the parts.
