[0001] The utility model relates to the technical field of lathe clamps, in particular to a multi-directional positioning clamp for horizontal lathe processing. Background Art

[0002] As a kind of mechanical tool, the fixture has a history of hundreds of years. The original fixture was simply handmade and had a short service life. With the continuous advancement of manufacturing technology and the development of industrialization, the manufacturing process of the fixture has gradually become more refined, intelligent and automated. At present, the fixture is still one of the four indispensable tools (tools, fixtures, gauges, and molds) in the manufacturing of electromechanical products. The fixture is gradually forming a small industry that is dependent on the machine tool industry or independent at home and abroad.

There are no auxiliary components to adjust the clamping angle, and the processing angle of the parts cannot be changed. When processing other positions, fixtures with different angles need to be replaced. This method is more cumbersome, which affects the processing efficiency. Utility Model Content

When the connecting rod 6 rotates, the meshing gear set 71 can be driven to rotate. A fixed shaft 72 is fixedly connected to one side of the surface of the meshing gear set 71. When the meshing gear set 71 rotates, the fixed shaft 72 can be rotated. One end of the fixed shaft 72 is fixedly connected to a right-angle gear 73. There are two right-angle gears 73 on the same side and they are horizontal with the vertical line. When the fixed shaft 72 rotates, the lower side can be The right angle gear 73 on the right side rotates, and the surface of the right angle gear 73 is meshed with the timing tooth belt 74.

When the upper right angle gear 73 rotates, the clamping block 13 can be driven to rotate. One side of the surface of the wheel 73 is fixedly connected with a fixed rod 15, and when the right-angle gear 73 on one side rotates, the fixed rod 15 can be driven to rotate. The surface of the fixed rod 15 is sleeved with a casing 16, and both sides of the inner cavity of the casing 16 are provided with a slide groove 8.
