Technical Field
[0001] The utility model relates to the field of die-casting part-taking devices, in particular to a gear-driven jaw. Background Technique
[0002] Die casting is a precision forming process, which is widely used in the manufacturing of complex parts in the fields of automobiles, motorcycles, communications, and general machinery. With the development of die-casting related technologies, the parts produced are becoming more and more complex and diverse. After the die-casting parts are cooled, they enter the mold-taking stage. At present, some manufacturers use manipulators for automatic part-taking, and use the jaws on the manipulator to clamp the die-cast products and send the products to a trimming machine for trimming operations. However, the existing jaw structures have limitations, with insufficient opening degree and span, and are not suitable for products with a large span. Moreover, the existing jaw structures are complex, with high manufacturing costs and inconvenient maintenance. Content of the Utility Model
[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a gear-driven jaw with a large clamping span, which can clamp die-cast products with a large span, and the structure of the gear and rack is simple, convenient for maintenance, and has low manufacturing costs.
[0004] A gear-driven jaw provided by the utility model includes:
[0005] A base, a first fixed seat arranged on the top of the base, a first rack and a second rack arranged horizontally side by side up and down, and a gear located between the first rack and the second rack;
[0006] Both the first rack and the second rack penetrate through the first fixed seat and are slidably connected to the first fixed seat. Both the first rack and the second rack are meshed and connected with the gear. One end of the first rack is fixedly connected with a first jaw, and the other end is connected with a driving member for driving its horizontal movement. One end of the second rack far away from the first jaw is fixedly connected with a second jaw. The telescopic movement of the driving member can drive the first jaw and the second jaw to move away from or close to each other.
[0007] Further, there are two first fixed seats symmetrically arranged about the gear.
[0008] Further, a second fixed seat is arranged between the two first fixed seats, and the gear is rotatably connected to the second fixed seat.
[0009] Further, two third fixed seats are symmetrically arranged about the gear on the top of the base. The third fixed seats are located on the side of the first fixed seat far away from the gear. A guiding column is fixedly arranged between the two third fixed seats. The guiding column sequentially penetrates through the first jaw and the second jaw, and both the first jaw and the second jaw are slidably connected to the guiding column.
[0010] Further, the driving member is a cylinder, the cylinder is fixed on the third fixing seat, and the telescopic end of the cylinder penetrates through the third fixing seat and is fixedly connected to one end of the first rack.
[0011] Further, protective plates are symmetrically arranged on the side surface of the base.
[0012] Further, the tops of the first clamping jaw and the second clamping jaw extend above the protective plate, and a first baffle and a second baffle are arranged above the protective plate between the first clamping jaw and the second clamping jaw.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0016] When the present utility model clamps a die-casting product, the driving member drives the first rack to move horizontally away from the driving member. The first rack drives the gear meshing with it to rotate, and the rotation of the gear drives the second rack meshing with it to move horizontally in the opposite direction of the movement of the first rack. The first rack and the second rack move in opposite directions, thereby driving the first clamping jaw and the second clamping jaw to move away from each other. The first clamping jaw and the second clamping jaw act synchronously, which is convenient for clamping die-casting products with a large span; the structure of the driving member driving and the gear-rack transmission is simple, which is convenient for realizing the span adjustment between the first clamping jaw and the second clamping jaw, and the manufacturing cost of the equipment is low.
