Detailed Implementation

[0014] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0015] Please see Figures 1 to 3The present invention provides a workpiece clamping fixture, comprising a fixed plate 1, several limiting components 2 and several pressure plates 3; The limiting component 2 is disposed on the side surface of the fixed plate 1. The limiting component 2 is fixedly connected to the fixed plate 1. Several limiting components 2 are arranged sequentially along the periphery of the fixed plate 1. The pressure plate 3 is connected to the limiting component 2 to fix the external workpiece 100 to the limiting component 2. Each of the limiting components 2 includes a left clamp 21, a right clamp 22, and a bottom support 23. The left clamp 21, the right clamp 22, and the bottom support 23 are all disposed on the side surface of the fixing plate 1, and the left clamp 21, the right clamp 22, and the bottom support 23 are arranged in a triangular shape. The distance between the left clamp 21 and the right clamp 22 is set, the distance between the left clamp 21 and the bottom support 23 is set, and the distance between the right clamp 22 and the bottom support 23 is set.

[0016] Specifically, in this embodiment, the fixing disk 1 is cuboid in shape, and there are sixteen limiting components 2. Each side surface of the fixing disk 1 is provided with four limiting components 2. Each limiting component 2 includes a left clamp 21, a right clamp 22, and a bottom support 23. The left clamp 21, right clamp 22, and bottom support 23 are arranged in a triangular shape. The left clamp 21, right clamp 22, and bottom support 23 protrude from the side surface of the fixing disk 1 at the same height. The external workpiece 100 is roughly butterfly-shaped. The structure in which the left clamp 21, right clamp 22, and bottom support 23 are spaced apart in pairs pre-fixes the external workpiece 100. The thickness of the workpiece 100 is greater than the thickness of the bottom support 23 protruding from the fixing disk. The height of the side surface is 1. The number of pressure plates 3 is four, with one pressure plate 3 corresponding to one side surface of the fixed plate 1. The working principle is as follows: First, a workpiece 100 is placed in a limiting component 2 with the surface 1a to be processed of the workpiece 100 facing upwards, thus completing the pre-positioning of sixteen workpieces 100. Then, the pressure plate 3 is fixedly connected to the limiting component 2 by external screw connectors to clamp the workpiece 100. Then, the combination of the fixed plate 1, the external workpiece 100 and the pressure plate 3 is moved to the external processing station. The external processing drill bit processes a preset number of blind holes on the workpiece 100, which satisfies the purpose of rapid fixing of batch workpieces 100 and synchronous processing of blind holes, thereby improving production efficiency.

[0017] By installing several limiting components 2 on the side wall of the fixed plate 1, each limiting component 2 consists of a left clamp 21, a right clamp 22 and a bottom support 23. The left clamp 21, right clamp 22 and bottom support 23 are arranged in a triangular shape. One limiting component 2 pre-fixes one external workpiece 100. Several external workpieces 100 are clamped between the fixed plate 1 and the pressure plate 3. The external processing drill bit simultaneously processes several blind holes 1b on the surface 1a to be processed of several workpieces 100, thereby improving production efficiency while ensuring processing accuracy and meeting production requirements.

[0018] The right clamp 22 of the limiting component 2 is connected to the left clamp 21 of the adjacent limiting component 2 to form a flat protrusion 24. This structure has the effect of saving space. The flat protrusion 24 is integrally formed with the fixed plate 1, which improves the positioning accuracy of different batches of workpieces 100.

[0019] The left clamp 21 and right clamp 22, located on adjacent side surfaces of the fixed disk 1, are integrally formed into an L-shaped protrusion 25. The L-shaped protrusion 25 is integrally formed with the fixed disk 1, which improves the positioning accuracy of workpieces 100 in different batches.

[0020] The limiting component 2 is provided with a threaded hole 201, which is located on the flat plate protrusion 24 and / or the bottom support 23. The pressure plate 3 is provided with a through hole 301, which penetrates the pressure plate 3 along the thickness direction. The central axis of the through hole 301 coincides with the central axis of the threaded hole 201. Two adjacent threaded holes 201 are arranged vertically, and three adjacent threaded holes are arranged in a triangular shape to improve the firmness of the connection between the pressure plate 3 and the limiting component 2, thereby satisfying the stability of fixing the external workpiece 100.

[0021] The fixed plate 1 is provided with a first upper groove 101, which is located directly above the flat plate protrusion 24 and / or the L-shaped protrusion 25. The first upper groove 101 is provided on the upper surface of the fixed plate 1. The pressure plate 3 is provided with a second upper groove 302, which is provided on the upper surface of the pressure plate 3. The first upper groove 101 and the second upper groove 302 are connected. This structure facilitates the clamping of external workpieces 100.

[0022] The fixture for clamping the workpiece also includes a base 4, which is connected to the fixed plate 1. The side of the base 4 protrudes from the side of the fixed plate 1. This structure improves the overall height and stability of the fixture for clamping the workpiece and facilitates connection with the connecting parts of the external workstation.

[0023] The base 4 and the fixing plate 1 are integrally formed to avoid processing errors caused by assembly errors and improve processing accuracy.

[0024] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
