[0004] However, the above-mentioned gear punching device does not have the function of centering the gear when punching the gear, which may cause the gear to shift during the punching operation, resulting in inaccurate punching position and affecting product quality. In view of this, a gear punching device with a positioning mechanism is proposed. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a gear punching device with a positioning mechanism, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a gear punching device with a positioning mechanism, comprising a workbench, an L-beam fixed above the workbench, a hydraulic press fixed above the L-beam, a hydraulic rod fixed to the output end of the hydraulic press, the hydraulic rod passing through and sliding above the L-beam, a connecting cylinder fixed to the upper sleeve of the hydraulic rod, a stamping die sleeved on the upper sleeve of the connecting cylinder, a die frame fixed above the workbench, a motor fixed to the workbench, a screw fixed to the output end of the motor, the screw passing through and rotating on the workbench, a clamping device provided on the workbench, a pressing device provided on the workbench, and an air blowing device provided on the workbench; The clamping device includes a sliding seat, a sliding spring, a sliding plate, a sliding column, an extrusion spring, an extrusion plate, a roller, a rotating rod, a torsion spring and a rotating plate. The sliding seat is threadedly connected to the screw rod, and the sliding seat slides in a slot on the workbench.

[0007] According to the above technical solution, a sliding plate slides on the notch of the sliding seat, a sliding spring is fixed on the sliding plate, and an end point of the sliding spring is fixed to the inner wall of the notch on the sliding seat.

[0008] According to the above technical solution, a sliding column slides in the slot on the sliding plate, an extrusion plate is fixed at the end point of the sliding column, a sliding spring is fixed on the extrusion plate, the end point of the sliding spring is fixed on the sliding plate, and a roller is rotatably connected in the slot on the extrusion plate.

[0009] The gear train is fixed on the gear and the roller is pressed downwards to move the sliding plate, so that the sliding plate is fixed on the gear train, and the roller is pressed downwards to move the sliding plate, so that the sliding plate is fixed on the gear train, and the roller is pressed downwards to move the sliding plate, so that the sliding plate is pressed downwards to move the roller. The endpoints are close to each other, so that the gear on the mold frame is centered, and the extrusion plate and roller are cooperated to make the gear centered and fixed above the mold frame. The sliding spring gives the sliding plate more displacement space, which allows the clamping device to adapt to the processing of gears of different sizes. When the gear processing is completed, the motor is controlled to reverse, so that the two sets of sliding seats move away from each other, and the two sets of sliding seats move away from each other, carrying the two sets of sliding plates and the two sets of sliding springs away from each other. The two sets of sliding plates move away from each other, carrying the two sets of sliding columns, two sets of extrusion springs, two sets of extrusion plates, two sets of rollers, two sets of rotating rods, two sets of torsion springs, and two sets of rotating plates away from each other. The extrusion plates and rollers no longer contact the gears, and the sliding columns are reset under the action of the extrusion springs. The sliding column is reset, and the rotating plate is reset with the rotating rod under the action of the torsion spring. The clamping device no longer contacts the gear, and the workers transport the stamped gears.

[0010] According to the above technical solution, the clamping device includes a connecting rod, a slide, a sleeve, a support spring, a T-shaped rod and a lower pressure plate. The connecting rod is fixed on the sliding seat, the slide slides on the workbench, and the connecting rod slides in the groove on the slide.

[0011] When the two sets of sliding seats are moved away from each other, the sliding seat brings the two sets of connecting rods closer to each other, so that the connecting rod pulls the slide plate downward, and the downward movement of the slide brings the sleeve downward, and the downward movement of the sleeve brings the support spring downward, and the downward movement of the support spring pulls the T-rod and the lower pressure plate downward, so that the lower pressure plate presses the gear. When the stamping is completed and the two sets of sliding seats move away from each other, the sliding seat brings the two sets of connecting rods away from each other, so that the connecting rod pulls the slide plate to reset upward, and the upward reset of the slide brings the sleeve upward, and the upward reset of the sleeve brings the support spring upward, and the upward reset of the support spring brings the T-rod and the lower pressure plate upward, so that the lower pressure plate no longer presses the gear downward.

[0012] According to the above technical solution, the blowing device includes a connecting spring, a pull plate, a piston rod, a piston plate, an air box and an air pipe. The connecting spring is fixed in a slot on the slide. The end point of the connecting spring is fixed with a pull plate, and the pull plate slides in the slot on the slide.

[0013] When the slider moves upward, the slider pulls the connecting spring to move upward, and the connecting spring pulls the pull plate downward, and the pull plate moves downward with the piston rod, and the piston rod moves downward with the piston plate, so that the piston plate slides upward on the inner wall of the air box, and the piston plate compresses the air in the air box, so that the air flows out from the air pipe, and the outgoing gas blows off the debris on the mold frame.

[0014] The present invention provides a gear punching device with a positioning mechanism. It has the following beneficial effects: (1) The present invention is provided with a clamping device, which drives the sliding seat to slide by rotating the screw rod, so that the sliding seat drives two sets of sliding plates, and the extrusion plates are close to each other to clamp the gear and fix the gear position, thereby preventing the gear from being displaced during punching and causing the gear punching to be offset, thereby reducing the loss of the gear; and when the two sets of sliding plates are close to each other, the extrusion plates squeeze the gear, so that the extrusion plates drive the sliding columns to squeeze the rotating plate, so that the rotating plate rotates on the rotating rod, and the two sets of rotating rods squeeze the gear so that the gear is centered under the assistance of the roller, so that the gear is in the center of the mold frame, thereby reducing the gear placement position offset, reducing the punching error, and improving the yield rate.

[0015] (2) The present invention is provided with a clamping device. When the two sets of sliding seats approach each other, the connecting rod pulls the slide plate downward, so that the sleeve on the slide plate moves downward with the T-plate and the pressure plate, so that the pressure plate presses the gear downward, so that the gear is placed horizontally on the mold frame, avoiding excessive deviation by the staff. The gear is placed obliquely on the mold frame, so that the stamping mold deviates from the predetermined position when punching, thereby reducing gear loss.

[0016] (3) The present invention is provided with an air blowing device. When the two sets of clamping devices are separated after the gear stamping is completed, the slide moves upward, so that the piston rod and the piston plate squeeze the air in the air box and blow it out from the air pipe. The gas in the air pipe blows out the debris dropped on the mold frame during the stamping, so that the subsequent gears will not be affected by the debris when they are placed, pressed and flat, thereby improving the accuracy of subsequent stamping and improving the yield rate.
