[0018] In order to make the technical scheme in the embodiments of the utility model clearer, the following will briefly introduce the drawings needed to be used in the embodiment description, and obviously, the drawings in the following description are only some embodiments of the utility model, and for those skilled in the art, other drawings can also be obtained according to these drawings without creative labor.

[0019] Referring to Figs. 1-3 An embodiment of the utility model discloses a kind of clamping jigs for the quick centering of workpiece, including the base (1) being equipped with through slot in the middle of upper surface, gasket (3) and tight screw (4);The through slot is used to place the workpiece;

[0020] The upper surface of the base (1) is marked with a plurality of size marks (2) along the length direction of the through slot, each size mark (2) is composed of a size value and a scale line, and all the size marks (2) take the middle scale line as a reference, and the distance between the scale line corresponding to the size mark and the middle scale line is taken as the size value corresponding to the size mark.

[0021] The side surface of the base (1) is provided with screw holes (6) for fixing workpieces by means of fixing screws (4); and the gaskets (3) are placed on the bottom of the through slot and tightly abut the fixing screws (4).

[0022] In the embodiment, the workpiece can be a mold, a copper public or other workpieces.

[0023] For example, Fig. 1 For example, Fig. 1 The length unit of the size value is cm, the workpiece is placed in the corresponding bottom gasket (3) according to the height of the workpiece during clamping, and the workpiece is clamped in the jig (1) according to the length of the workpiece, for example, a 40cm-long workpiece needs to align the right end of the workpiece to be machined with the 20cm scale line on the right side, and a 35cm-long workpiece needs to align the left end of the workpiece to be machined with the 17.5cm scale line on the left side; then the fixing screws (4) pass through the screw holes (6) and simultaneously top the side gaskets (3) and the workpiece to achieve the purpose of fixation, and finally the pneumatic fixing head (5) is inserted into the machine table, and then the fixed coordinates can be input to start machining the workpiece.

[0024] The embodiment of the utility model discloses a position scale table is engraved on the surface of jig, and quick centering can be realized according to the length of workpiece and the corresponding scale table position during clamping without table calibration, which is quick and convenient to operate, and can effectively reduce the clamping time and standby cost in actual machining.

[0025] In an alternative embodiment, the middlemost scale line among all the size marks (2) is located on the symmetry axis of the upper surface of the base (1).

[0026] In another alternative embodiment, the middlemost scale line among all the size marks (2) is taken as a boundary, the distance between the adjacent scale lines in one direction is A, and the distance between the adjacent scale lines in the other direction is B, and A is not equal to B.

[0027] For example, Fig. 1 For example, when the workpiece is clamped in the jig (1) according to the length of the workpiece, if the workpiece is 40cm long, the right end of the workpiece to be machined needs to be aligned with the 20cm scale line on the right side, and if the workpiece is 35cm long, the left end of the workpiece to be machined needs to be aligned with the 17.5cm scale line on the left side, so that at least two kinds of workpieces of different sizes can be quickly centered.

[0028] In another alternative embodiment, the gasket (3) is also placed on the bottom of the through slot of the base (1) for adjusting the height of the workpiece in the through slot.

[0029] In another alternative embodiment, the set screw (4) is a glass bead screw.

[0030] In another alternative embodiment, the bottom of the base (1) is fixed with a pneumatic fixing head (5) for fixing on the machining station of the corresponding machining equipment of the workpiece.

[0031] The content disclosed by the embodiments of the utility model only is the preferred embodiment of the utility model, and is used for explaining the technical scheme of the utility model, and is not limited to it; although the utility model is explained in detail by referring to the foregoing embodiments, those skilled in the art should understand that; it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement is carried out to part of technical features; and these modifications or replacements do not make the essence of the corresponding technical scheme deviate from the spirit and range of the technical scheme of the embodiments of the utility model.
