Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: the clamping device comprises a workbench 1, a support 2, a driving rod 3, a torsion spring 4, a second clamping block 5, a first clamping groove 6, a second clamping groove 7, a through hole 8, a connecting rod 9, a protrusion 10, a first connecting rod 11, a pin shaft 12, a second connecting rod 13, a through groove 14, a limiting groove 15, a limiting block 16 and a first clamping block 17.
The embodiment is substantially as shown in figures 1, 2 and 3 of the accompanying drawings: the double-sided chamfering machine holder comprises a workbench 1, wherein a support 2 is arranged on the upper end face of the workbench 1, and the support 2 is connected with the workbench 1 through bolts. The upper end face of the workbench 1 is provided with a first clamping block 17, and the first clamping block 17 is connected with the workbench 1 through a bolt. Support 2 upper portion is equipped with second grip block 5, and second grip block 5 and the vertical sliding fit of support 2, 2 lateral parts of support are equipped with drive second grip block 5 along support 2 gliding drive division from top to bottom. Specifically, the drive division includes actuating lever 3, 3 middle parts of actuating lever are connected through round pin 12 rotation with support 2, actuating lever 3 includes first connecting rod 11 and second connecting rod 13, first connecting rod 11 is equipped with logical groove 14, first connecting rod 11 and second connecting rod 13 tip are articulated through the connecting pin, first connecting rod 11 is equipped with spacing groove 15 with second connecting rod 13 articulated tip, second connecting rod 13 tip be equipped with spacing groove 15 complex stopper 16, actuating lever 3 is equipped with torsional spring 4 with support 2 junction. The second clamping block 5 is provided with a protrusion 10, the protrusion 10 is welded with the second clamping block 5, and the protrusion 10 is clamped in the through groove 14 and can slide along the through groove 14.
The clamping device further comprises a connecting rod 9, a through hole 8 is formed in the upper portion of the support 2, the connecting rod 9 penetrates through the through hole 8 and is in sliding fit with the through hole 8, and the end portion of the connecting rod 9 is fixedly connected with the second clamping block 5 through a screw.
