Description

Technical Field

[0001] The utility model relates to the field of numerically controlled machine tools, in particular to a clamping tool for a multi-station numerically controlled machine tool. Background Art

[0002] At present, a Chinese utility model with the announcement number CN217991759U discloses a multi-station clamping tool for aluminum profile processing, which relates to the field of clamping tool technology. The multi-station clamping tool for aluminum profile processing includes a workbench, a base is fixedly installed on the upper surface of the workbench, and an adjustment mechanism is arranged inside the base. The adjustment mechanism includes a dual-axis motor, a clamping seat and an adjustment knob 1. The dual-axis motor is fixedly installed on the inner wall of the base, and the bottom end of the clamping seat is fixedly installed on the upper surface of the threaded sleeve. In order to improve the adjustment force of the device on the aluminum profile, the multi-station clamping tool for aluminum profile processing is provided with an adjustment mechanism, which cooperates with the drive motor, the adjustment screw 2 and the threaded transmission plate, so that the staff can change the height of the adjustment seat, so that the aluminum profile can be adjusted accordingly to complete more complex aluminum profile processing operations, reduce the number of times the staff disassembles and assembles, and thus improve the overall processing efficiency of the device.

[0003] The existing clamping tooling cannot adjust the position of the clamping mechanism. Generally, multiple groups of clamping mechanisms are installed on the clamping tooling, and the clamping mechanisms are fixedly installed on the tooling, resulting in a fixed spacing between the clamping mechanisms, which is difficult to adjust. During processing, due to the different sizes of the workpieces being processed, if the spacing between the clamping mechanisms is small, it is difficult to process. If the spacing is large, the processing time is increased, which is inconvenient to use and to replace the clamping mechanism. During processing, it is often necessary to select the required fixture according to the processed parts, and the fixture is generally fixed to the tooling with bolts. When replacing, tools are required to disassemble and assemble it. The disassembly and assembly process is relatively cumbersome, which increases the workload and reduces the work efficiency. In order to solve the above-mentioned problems, we propose a clamping tool for a multi-station CNC machine tool. Utility Model Content
