Technical Field

[0001] This utility model relates to a gripper, and more particularly to a gripper device for vertically flipping shell-type parts, belonging to the field of shell-type parts processing technology. Background Technology

[0002] The shell is a sheet-like structure formed by inner and outer curved surfaces. Its thickness t is much smaller than the minimum radius of curvature R of the middle surface and the plane size. It is a general term for thin shells and medium-thick shells. The main types on the market are plastic shells, aluminum profile shells, sheet metal shells, stainless steel shells, etc. During the processing of shell parts, it is necessary to use a gripper to grasp them in order to process them at different angles.

[0003] However, existing grippers for shell-type parts have high maintenance costs, low gripping and part flipping positioning accuracy, and are not convenient for clamping both sides of the shell at the same time, resulting in unstable clamping force and failing to meet the processing requirements of production line equipment for shell-type parts at different angles.

[0004] To address the aforementioned technical problems, a gripper device for vertically flipping shell-type parts is proposed. Utility Model Content

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figure 1-5 As shown, this utility model embodiment provides a gripper device for vertically flipping shell-type parts, which consists of a frame 1, a clamping assembly 2, a flipping assembly 3, and a positioning clamping plate assembly 4;

[0030] The clamping assembly 2 is installed on one side of the frame 1, the flipping assembly 3 is installed on one side of the clamping assembly 2, and the positioning clamping plate assembly 4 is installed at the output end of the flipping assembly 3.

[0031] The clamping assembly 2 includes a linear guide rail 21 installed on the bottom surface of the frame 1. Two sets of left and right clamping sliding base plates 22 are installed on the lower part of the linear guide rail 21. The two sets of left and right sliding base plates 22 are connected by a ratchet mechanism 23. A connecting block 24 is fixedly installed on the right sliding base plate 22. The connecting block 24 is driven by a clamping cylinder 25. The clamping cylinder 25 is fixedly installed on the bottom surface of the frame 1. The frame 1 is equipped with three sets of proximity sensors 26 to sense the loosened position, the position with a part clamped, and the position without a part clamped, respectively.

[0032] The flipping assembly 3 consists of two sets, left and right, including a flipping body 31 installed at the lower part of the clamping assembly 2, a flipping cylinder 32 installed at the top of the flipping body 31, the flipping cylinder 32 connected to a drive toothed guide shaft 33, the toothed guide shaft 33 meshing with a flipping gear shaft 34, and the flipping gear shaft 34 driving the flipping follower limit block 35 to flip through a tension sleeve; a positioning block 36 is installed on the side of the flipping body 31, and angle adjustment limit bolts 37 are installed on both the upper and lower sides of the positioning block 36, and angle monitoring sensors 38 are installed on both the upper and lower sides of the positioning block 36, and the angle monitoring sensors 38 sense the flipping follower limit block 35.

[0033] The positioning clamping plate assembly 4 consists of a left positioning structure and a right positioning structure. The left positioning structure includes a left positioning plate 411 connected to the flipping gear shaft 34. A left contour clamping block 412 for clamping shell-type parts is installed on the left positioning plate 411.

[0034] The right positioning structure includes a right positioning plate 421 connected to the flip gear shaft 34, and a right contour clamping block 422 for clamping shell-type parts is mounted on the right positioning plate 421.

[0035] The ratchet mechanism 23 includes a ratchet 231 and a connecting rod 232. The two connecting rods 232 are respectively installed at both ends of the ratchet 231. One end of the connecting rod 232 is connected to the sliding base plate 22. When the clamping cylinder 25 retracts, the connecting block 24 drives the right sliding base plate 22 to move to the left. The right sliding base plate 22 drives the right connecting rod 232 to make the ratchet 231 swing clockwise around the center point. That is, the right connecting rod 232 moves to the left, the left connecting rod 232 moves to the right, and the left connecting rod 232 drives the left sliding base plate 22 to move to the right, which can realize the clamping action. When the clamping cylinder 25 extends, the right sliding base plate 22 moves to the right, and the left sliding base plate 22 moves to the left, which realizes the releasing action.

[0036] In operation, this utility model achieves the following: During clamping, the clamping cylinder 25 drives one side sliding base plate 22, which in turn drives the other side sliding base plate 22 via the ratchet mechanism 23, thus clamping both sides simultaneously. When the clamping cylinder 25 retracts, it works with the connecting block 24 to move the right sliding base plate 22 to the left. The right sliding base plate 22 then drives the right connecting rod 232 to make the ratchet 231 swing clockwise around the center point. That is, the right connecting rod 232 moves to the left, the left connecting rod 232 moves to the right, and the left connecting rod 232 drives the left sliding base plate 22 to the right, thus achieving the clamping action. When the clamping cylinder 25 extends, the right sliding base plate 22 moves to the right, and the left sliding base plate 22 moves to the left, thus achieving the releasing action. This provides reliable clamping force and smooth operation. During flipping, the flipping cylinder 32 drives the toothed guide shaft 33 to drive the flipping gear shaft 34, which in turn drives the positioning clamping plate assembly 4 to perform a 180° flipping action.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
