Description

Technical Field

[0001] The utility model belongs to the technical field of drilling machine fixtures, in particular to a drilling machine fixture. Background Art

[0002] Drilling machine fixtures are devices used to fix workpieces on drilling machines. Drilling machine fixtures play a vital role in drilling machine processing. They can not only ensure processing accuracy and improve production efficiency, but also expand the scope of use of machine tools and reduce labor intensity. They are an indispensable and important tool in modern mechanical processing.

[0003] For example, Chinese patent publication number CN219967138U discloses a drilling machine fixture, comprising a fixture table, a clamping assembly provided on the fixture table, and an ejection assembly provided on the fixture table. The clamping assembly comprises four rotating rods rotatably connected to the top inner wall and the bottom inner wall of the fixture table, a drive shaft rotatably connected to one side of the fixture table, and four clamping plates slidably sleeved within the fixture table. A worm is fixedly sleeved on the outer side of the drive shaft, a driven worm gear is fixedly sleeved on the outer side of one of the four rotating rods, and the worm and the driven worm gear are meshed. A sprocket and a cam are fixedly sleeved on the outer side of each of the four rotating rods. The utility model has the following advantages and effects: the workpiece can be clamped and fixed in the front, back, left, and right directions, making the clamping more secure, and an avoidance hole is provided to prevent the drill bit from colliding with the top of the fixture table.

[0004] The above patent has the following problems:

[0005] This patent has some shortcomings when used. For example, when this device clamps a workpiece, because the four clamping plates move simultaneously toward the center of the workbench, when clamping a rectangular workpiece, only two clamping plates can clamp the rectangular workpiece, and the other two clamping plates cannot play a clamping role, resulting in reduced clamping stability. In addition, when the workpiece to be clamped is soft, the workpiece may deform during the clamping process, thereby damaging the workpiece. In view of this, we propose a drilling machine fixture.
