Description

Technical Field

[0001] The utility model relates to the technical field of clamping tables, in particular to a workpiece clamping table. Background Art

[0002] In mechanical processing, the workpiece needs to be clamped and fixed on the clamping table so that the machine tool can process it. At present, most of the existing clamping tables are fixed table settings with a low degree of automation. For workpieces with relatively complex structures, the processing technology will be more complicated. When processing such workpieces with complex structures, it may be necessary to constantly move their positions or change their angles. In this case, the staff usually completes the cumbersome processing technology by constantly changing their own positions or manually adjusting the angles of the workpieces to be processed. However, in some workshops with complex construction conditions, it is very inconvenient for the staff to move their positions, and their processing efficiency is greatly reduced due to environmental restrictions. At the same time, due to the discontinuous processing actions of the staff, it may lead to problems such as poor workpiece processing quality, low processing accuracy, and long processing time. Utility Model Content

[0003] The utility model discloses a workpiece clamping table, which solves the problem that traditional clamping tables are mostly fixed table settings with a low degree of automation. When processing workpieces with complex structures, it is very inconvenient for workers to move their positions, and the processing efficiency is greatly reduced due to environmental restrictions. At the same time, since the processing actions of the workers are discontinuous, the workpiece processing quality may be poor, the processing accuracy is not high, and the processing time is long.

[0004] In order to solve the above technical problems, the utility model specifically adopts the following technical solutions:

[0005] A workpiece clamping table comprises a base, a sliding mechanism is arranged on the top of the base, the sliding mechanism comprises an X-axis sliding mechanism and a Y-axis sliding mechanism which are arranged perpendicular to each other, the X-axis sliding mechanism is horizontally arranged on the top surface of the base and extends along the length direction of the base, the Y-axis sliding mechanism is horizontally arranged on the top surface of the X-axis sliding mechanism and enables the Y-axis sliding mechanism to move horizontally along the length direction of the base, a lifting mechanism is arranged on the top surface of the Y-axis sliding mechanism and enables the lifting mechanism to move horizontally along the length direction perpendicular to the base, a workbench for fixing the workpiece is horizontally arranged on the top surface of the lifting mechanism and enables the workbench to move in the vertical direction, and a second motor for driving the workbench to rotate around its own axis is arranged on the lifting mechanism.

[0006] Compared with the prior art, the utility model has the following beneficial effects:

[0007] The workpiece is placed on the workbench. When processing a workpiece with a complex structure, if the workpiece needs to be moved, the movement control of the workpiece in the horizontal direction can be realized through the X-axis sliding mechanism and the Y-axis sliding mechanism, and the movement control of the workpiece in the vertical direction can also be realized through the lifting mechanism, which effectively avoids the inconvenience of processing caused by the staff due to environmental restrictions; and if the processing angle of the workpiece needs to be changed, the workbench can be controlled to rotate around its own axis through the second motor, so that the staff does not need to frequently manually adjust the angle of the workpiece to be processed, which greatly improves the processing efficiency of the workpiece. The utility model has a high degree of automation and strong practicality. By setting the X-axis sliding mechanism, the Y-axis sliding mechanism, the lifting mechanism, the workbench and the second motor, the multi-directional movement and all-round rotation of the workpiece without dead angles can be realized quickly and accurately to adapt to the cumbersome processing steps of the workpiece with a complex structure, and effectively solves the problems of poor processing quality and low processing accuracy caused by the staff's own environmental restrictions and discontinuous processing actions, and also greatly improves the processing efficiency of the workpiece.
