Description

Technical Field

[0001] The utility model specifically relates to the technical field of multi-angle adjustment of clamps, in particular to a multi-directionally adjustable rotating clamp for a lathe. Background Art

[0002] When a lathe processes a workpiece, it is necessary to adjust the workpiece at multiple angles to meet the processing needs and operation requirements of different angles, provide convenience for the processing of complex workpieces, and adjust the clamped workpiece at multiple angles through the adjustment structure to effectively and accurately control the angle and position of the workpiece to ensure the accuracy and size of the workpiece processing.

[0003] At present, traditional lathes usually fix the workpiece during the processing process and achieve the processing effect by moving the tool. This may cause the tool to have a large stroke during the processing. When the tool moves for a long time and a long distance, the processing accuracy of the lathe may be reduced and the processing accuracy of the workpiece cannot be effectively guaranteed. In addition, when clamping the workpiece, the traditional lathe needs to repeatedly adjust the positioning of the workpiece on the workbench, which reduces the work efficiency.

[0004] After searching, Chinese patent publication number CN202320632546.3 discloses a fixture that facilitates multi-angle adjustment; it includes a support base, a support leg fixed to the bottom of the support base, a groove formed on the upper surface of the support base, an adjustable angle support plate disposed within the groove, a set of extrusion pads rotating within the support plate, and a threaded rod provided on the outer wall of the support plate to control the rotation of the extrusion pads;

[0005] When the clamp in the above patent is adjusting the angle, the support plate rotates in the arc groove through the limit rods at both ends to achieve a certain adjustment of the workpiece fixed on the two extrusion pads. The support plate is installed inside the groove, so that when the angle is adjusted, the adjustment angle of the support plate will be subject to a certain limit, and the extrusion pad in the above patent is clamped on the workpiece through the limit spring. In this way, during the processing, when the workpiece comes into contact with the processing tool, the workpiece will vibrate violently, and the processing accuracy cannot be effectively guaranteed, and even the workpiece may fall off. Utility Model Content

[0006] The purpose of the present utility model is to provide a multi-directional adjustable rotary clamp for a lathe. In this structure, the workpiece is mounted on the clamping jaw, and the clamping jaw can drive the workpiece to rotate through a third drive motor. The mounting seat is cooperated and installed in a dovetail groove provided on the support plate, which is convenient for replacing the clamping jaw. The support plate is driven to rotate by a rotating drum to realize circular rotation of the support plate. In this way, when processing the workpiece, the stroke of the processing tool is reduced by a certain amount, thereby effectively improving the processing efficiency. The second drive motor drives the rocker arm to swing at a certain angle, thereby realizing the overall angle adjustment of the second adjustment component. The first adjustment component moves linearly along the slide rail, effectively realizing the adjustment of the position of the workpiece, greatly improving the processing efficiency; so as to solve the problems of the above-mentioned background technology.
