Technical Field

[0001] The utility model belongs to the technical field of mechanical clamps, in particular to an auxiliary mechanical clamp for a numerically controlled machine tool. Background Art

[0002] With the ever-changing market demand and increasingly fierce commodity competition, the cycle of mechanical product replacement is getting shorter and shorter, and the proportion of multi-variety and small-batch production is getting higher and higher. In order to meet the needs of this situation, at present, in the production of mechanical industry, it is often necessary to clamp the processed objects to ensure smooth production and processing. Therefore, the clamp plays a very important role in the production of mechanical industry.

[0003] Most of the existing clamps need to be turned manually to clamp the workpiece. When the workpiece is processed, the clamp must be unscrewed manually. This is not only time-consuming and labor-intensive, resulting in low work efficiency, but also creates safety hazards. The scope of use is small, and the workpiece cannot be positioned accurately.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0006] The utility model is an auxiliary mechanical fixture for a numerically controlled machine tool, comprising a box body; the four corners of the top of the box body are fixedly connected with L-shaped support plates;

[0007] The L-shaped support plate is fixedly connected to a first fixing strip relative to the inner wall; one side of the first fixing strip is fixedly connected to two mutually symmetrical hinge seats; the two hinge seats are rotatably connected to a connecting rod; the inner wall at the top end of the L-shaped support plate is fixedly connected to a first shaft seat; the first shaft seat is rotatably connected to a bidirectional threaded rod;

[0008] The bidirectional threaded rod is sleeved with two mutually symmetrical threaded sleeves on the circumferential side surface; a second hinge seat is fixedly connected to one side of the threaded sleeve; a triangular plate is fixedly connected to the other side of the threaded sleeve; an electric telescopic rod is fixedly connected to the inclined surface of the triangular plate; a second fixing strip is fixedly connected to the end of the electric telescopic rod; a splint is fixedly connected to one side of the two fixing strips.

[0009] Furthermore, the end of the connecting rod is hinged to the second hinge seat.

[0010] Furthermore, a second shaft seat matching with the bottom end of the bidirectional threaded rod is fixedly connected inside the bottom end of the box body; and a first bevel gear is fixedly connected to the peripheral side of the bidirectional threaded rod away from the second shaft seat.

[0011] Furthermore, two mutually symmetrical bidirectional motors are fixedly connected to the inner wall of the bottom end of the box body; a rotating shaft is connected to the rotating shaft end of the bidirectional motor; a second bevel gear is fixedly connected to the end of the rotating shaft; and the second bevel gear and the first bevel gear are mutually gear-driven.

[0012] Furthermore, the edges at both ends of the box body are provided with T-shaped sliding grooves matching with the bottom ends of the clamping plates.

[0013] The utility model has the following beneficial effects:

[0014] The utility model cooperates with a box body, an L-shaped supporting plate, a bidirectional threaded rod, a clamping plate and a bidirectional motor. The bidirectional motor drives the first bevel gear and the second bevel gear at the rotating shaft end to mesh with each other for transmission. The first bevel gear drives the bidirectional threaded rod to rotate. Two threaded sleeves are provided on the circumferential side of the bidirectional threaded rod to cooperate with the connecting rod, so that the two threaded sleeves can move in both directions. Finally, an electric telescopic rod is provided on one side of the two threaded sleeves to push the two clamping plates to clamp and fix the workpiece. The utility model has the advantages of accurate positioning, simple operation, improved work efficiency and strong practicality.
