Detailed Description
Referring to fig. 1 to 4, fig. 1 to 4 are schematic structural views of an embodiment of the present invention.
As shown in fig. 1 to 4, a clamping tool suitable for workpieces of multiple specifications comprises an upper positioning panel 1 and a lower positioning panel 2 which are horizontally arranged, wherein the upper positioning panel 1 is located above the lower positioning panel 2, and the upper positioning panel 1 is fixedly connected with the lower positioning panel 2 through a support plate 3; the top surface of the upper positioning panel 1 is fixedly provided with an installation auxiliary plate 4, and the installation auxiliary plate 4 is provided with a central hole 41 with a vertical axis; still include the dabber 5 and the cap bolt 6 of the vertical setting of axis, the lower extreme of dabber 5 is fixed set up in the centre bore 41, the nut of cap bolt 6 up, the upper end of dabber 5 is provided with the cooperation centre gripping screw 51 of 6 lower extremes of cap bolt, just the nut of cap bolt 6 with be provided with U groove parallel washer 61 between the upper end of dabber 5.
Specifically, a fixing hole 11 with a vertical axis is arranged on the upper positioning panel 1, and the fixing hole 11 is located right below the central hole 41; the lower end of the mandrel 5 is provided with a fixing screw hole 52 with a vertical axis, the fixing hole 11 is internally provided with a mounting stud 7, the upper end of the mounting stud 7 is matched with the fixing screw hole 52, and the lower end of the mounting stud 7 is matched with a mounting nut 71 positioned at the bottom of the upper positioning panel 1.
