The principle of the utility model is as follows: one end of the bracket is the loading station, and the other end of the bracket is the unloading station; when the clamp is in the loading station, the two cylinders respectively drive the two clamping arms to clamp the material. After the material is clamped, the motor starts, the motor drives the gear, and the gear moves on the rack to drive the motor. The motor drives the clamp to move toward the unloading station through the mounting plate and the support plate. When the clamp reaches the unloading station, the two cylinders respectively drive the two clamping arms to release the material, thereby realizing automatic loading of the material.

[0005] As an improvement, first slide rails are provided on both sides of the top of the bracket, and first sliding blocks slidably matched with the first slide rails are provided at both ends of the support plate, and the first slide rails are arranged parallel to the rack.

[0006] As an improvement, a second slide rail perpendicular to the first slide rail is provided on the top of the support plate, and the clamping arm is slidably matched with the second slide rail via a second sliding block.

[0007] As an improvement, the clamp arm includes an L-shaped portion and a connecting portion, one end of the L-shaped portion is connected to the connecting portion by a bolt, the second slider is arranged at the bottom of the connecting portion, a connecting ear is provided on one side of the connecting portion, and the telescopic rod of the cylinder is connected to the connecting ear.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] The motor and the fixture can be moved as one through the meshing of the gear and the rack, and the movement response is fast and accurate; the two clamping arms are independently driven by two cylinders, and the clamping force of the fixture is adjustable; the longitudinal and lateral movements of the fixture are guided by the slide rails, and the stability is high.
