Description

Technical Field

[0001] This utility model relates to a workpiece clamping or positioning device, and in particular to a combined limiting component. Background Technology

[0002] In machining, ensuring the positioning accuracy of the workpiece is a crucial foundation for producing qualified finished products. Limiting components are commonly used to restrict and adjust the workpiece's position. Common limiting components include V-blocks and rectangular steps. V-blocks restrict the radial movement of cylindrical workpieces and are frequently used in the machining of cylindrical workpieces. Rectangular steps are typically used to limit the movement of square workpieces with a rectangular cross-section.

[0003] Because the size of the limiting component is fixed, the number of workpieces it can be matched with is limited, and the applicable range of the limiting component is small. Because there are many types of workpieces with different external dimensions, the limiting component needs to be frequently replaced as the workpiece changes. Moreover, the replacement of the limiting component requires re-alignment. Such frequent adjustment and calibration work reduces the limiting efficiency.

[0004] Therefore, there is an urgent need for a limiting component that has a wide range of applications and high limiting efficiency. Summary of the Invention

[0022] The first I-shaped groove 4 includes an I-shaped groove wall 10 and an I-shaped groove bottom 11. The I-shaped groove wall 10 is perpendicular to the first limiting surface 2, and the I-shaped groove bottom 11 is parallel to the first limiting surface 2.

[0023] This utility model also includes a second limiting surface 5, which is the same as the first limiting surface 2. The second limiting surface 5 can be any side of the body 1 other than the first side surface W, such as... Figure 2 As shown, the second side surface X is selected as the second limiting surface 5 in this embodiment.

[0024] The second limiting surface 5 is provided with a second V-groove 6. The second V-groove 6 includes two intersecting V-groove walls 8 and a V-groove bottom 9, wherein the V-groove walls 8 are perpendicular to the second limiting surface 5, and the V-groove bottom 9 is parallel to the second limiting surface 5.

[0025] A second I-groove 7 is provided on the side of the second limiting surface 5 near the opening of the second V-groove 6, perpendicular to the direction of the opening of the second V-groove 6. For example... Figure 2 As shown, in this embodiment, the second V-shaped groove 6 opens towards the third side Y, and the second I-shaped groove 7 is disposed at the intersection of the second side X and the third side Y.

[0028] To broaden the applicability of the combined limiting component, V-grooves and / or I-grooves of different sizes can be provided on the four sides of the main body 1.

[0030] In use, the combination of the limiting component body 1 can be adjusted according to the shape and size of the workpiece. For cylindrical workpieces, such as...
