Description

Technical Field

[0001] The utility model relates to the technical field of drilling machines, in particular to a clamping fixture for drilling machines. Background Art

[0002] A drilling machine is a machine tool that mainly uses a drill to make holes on a workpiece. Usually, the rotation of the drill is the main motion, and the axial movement of the drill is the feed motion. The drilling machine has a simple structure and relatively low processing accuracy. It can drill through holes and blind holes. By replacing special tools, it can expand, countersink, ream holes or perform tapping and other processing. During the processing, the workpiece does not move, the tool moves, aligns the center of the tool with the center of the hole, and rotates the tool (main motion). The characteristic of a drilling machine is that the workpiece is fixed and the tool rotates.

[0003] In the field of lathe processing, many products need to be fixed by clamping the outer shape to facilitate subsequent processing. Existing clamping jigs usually achieve clamping through an external support mechanism. Specifically, the external support mechanism extends into the groove or hole of the product and then expands outward to support the groove wall or hole wall to achieve the purpose of fixing the product. It is easy to understand that the clamping jig is only applicable to products with grooves or holes, and for other products, the clamping jig cannot achieve effective fixation. In other words, the practicality of the clamping jig is poor.

[0004] Traditional clamping jigs are mostly used for manual clamping. Frequent switching of multiple batches leads to low processing efficiency. In addition, the contact area of ​​different clamping components is small, resulting in poor clamping stability of the drilling machine. For this reason, we propose a clamping jig for drilling machines. Utility Model Content
