Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical feeding, in particular to a long-sized thin plate material clamp. Background Art

[0002] Sheet metal is a commonly used raw material in mechanical automation production. For the convenience of processing and production needs, the loading end often uses long and thin sheets. Due to the long size, the sheet metal will bend and sink due to gravity, so during transportation or loading, the sheet metal will bend and the positioning cannot be controlled.

[0003] At present, multi-point clamping is generally adopted, that is, multiple clamping mechanisms are set on the long side of the sheet. However, this method requires very high coordination accuracy, so that several clamping mechanisms must cooperate uniformly, or there will still be problems with positioning that cannot be controlled. At the same time, because the clamping mechanism is relatively small and the clamping force is limited, when the sheet is heavy, there is a risk of falling. Summary of the Invention

[0004] In order to solve the above technical problems, a technical solution adopted by the present invention is:

[0005] A long thin plate fixture comprises a frame body and at least two sets of clamping assemblies mounted on the frame body, wherein the two sets of clamping assemblies are symmetrically arranged;

[0006] The frame body is provided with a first clamping portion, and the first clamping portion is used to cooperate with the clamping assembly for clamping;

[0007] The clamping assembly includes a driving element and a driving plate mounted on the output end of the driving element, the clamping assembly also includes a clamping plate and a plurality of groups of guide posts, the driving plate is provided with a plurality of driving holes, the driving holes are provided with driving posts, the driving posts are fixedly connected to the clamping plate, the driving holes are tilted downward along the horizontal direction of the driving plate, and the second group of driving holes are tilted and mirrored;

[0008] The clamping plate is provided with a second clamping portion and a guide hole for accommodating the guide column. When the driving plate moves leftward / rightward along the horizontal direction, the clamping plate can be driven to open / clamp on the guide column.

[0009] Furthermore, several groups of limit plates are installed on the frame body, the limit plates are provided with limit columns, and the drive plate is provided with limit holes for accommodating the limit columns. When the drive element drives the drive plate to move, the limit columns in the limit holes can limit the movement distance of the drive plate.

[0010] Furthermore, the driving hole has an inclination angle of 15-25°.

[0011] Furthermore, the driving element is a cylinder.

[0012] Beneficial effects of the utility model:

[0013] The utility model uses two sets of symmetrically arranged driving plates to simultaneously drive the clamping part to open and clamp, forming an ultra-long clamping structure, which can clamp the entire long side of the long-sized sheet material, greatly enhancing the clamping force of the clamping assembly and preventing the sheet material from falling. At the same time, the clamping part is integrally formed, which is convenient for positioning control and improves the feeding accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
