Embodiment
[0030] see Figure 1 to Figure 5 , the present invention provides a locking mechanism, including a tensioning shaft 21, a clamping disc 22, a pushing mechanism and a guiding mechanism; wherein, the clamping disc 22 is provided with a through hole 221, and the upper end of the tensioning shaft 21 is provided with a pressing part, the shape of the pressing part matches the through hole 221; the guiding mechanism is arranged at the lower end of the tensioning shaft 21, and the pushing mechanism can drive the tensioning shaft 21 to move vertically and rotate along the guiding mechanism; when the pressing part and When the through hole 221 overlaps, the tensioning shaft 21 and the clamping disk 22 are in a loose state; when the pressing portion and the through hole 221 are staggered, the tensioning shaft 21 and the clamping disk 22 are in a clamping state.
[0031] Preferably, the profile of the through hole 221 is quincunx.
[0032] In addition, the outline of the through hole 22...

The invention relates to the technical field of machining tools, in particular to a locking mechanism. The locking mechanism comprises a tensioning shaft, a clamping disc, a pushing mechanism and a guiding mechanism, wherein a through hole is formed in the clamping disc, a pressing part is arranged at the upper end of the tensioning shaft, and the shape of the pressing part is matched with that of the through hole; the guide mechanism is arranged at the lower end of the tensioning shaft, and the pushing mechanism can drive the tensioning shaft to vertically move and rotationally move along the guide mechanism; the tensioning shaft and the clamping disc are configured in the mode that when the pressing part coincides with the through hole, the tensioning shaft and the clamping disc are in a loosened state; and when the pressing part and the through hole are staggered, the tensioning shaft and the clamping disc are in a clamping state. By the adoption of the locking mechanism, when the workbench is replaced, convenience and rapidness are achieved, the working efficiency is improved, the size precision of continuous machining of parts after the workbench is replaced is guaranteed, meanwhile, the manufacturing cost is reduced, and the practicability is improved.
Description
technical field [0001] The invention relates to the technical field of processing machine tools, in particular to a locking mechanism and an exchange workbench with the locking mechanism. Background technique [0002] The exchange workbench means that multiple workbenches can be quickly positioned and clamped on one or more bases to ensure positioning accuracy and clamping rigidity. The exchange workbench is applied to the workbench of the machining center and the automatic production line. When one part is processed, another part is clamped at the same time, or the workpiece is clamped once and transferred to different machine tools with the workbench to complete the entire process. Exchanging worktables can improve processing efficiency, save auxiliary time, and realize automation. [0003] At present, the typical structure of the exchange workbench adopts four positioning cones for positioning, which is difficult to manufacture. Only a few manufacturers can produce it, a...
