detailed description

The design concept of the utility model is: the shape of the workpiece is regular, and the positioning and clamping conditions are suitable for the use of automatic equipment. The multi-layer linear silo is used to store more workpiece blanks. Each layer is set with a certain slope. Under the action of gravity, the workpiece automatically enters the feeding area, and the workpiece is pushed into the pneumatic chuck through the feeding cylinder for clamping. After completion, drive the receiving device closer, and the workpiece slides out along the special track for collection.

Below in conjunction with accompanying drawing, the utility model is described in further detail.

The structure of a kind of automatic loading and unloading device of the utility model is shown in Figure 1-3, comprises stand 1, slope slideway 2, feeding cylinder 3, pushing material cylinder 4, unloading cylinder 5, receiving material cylinder 6. The feeding cylinder 3, the material pushing cylinder 4, the blanking cylinder 5, and the material receiving cylinder 6 are of the same type, all of which are common telescopic cylinders.

The pushing cylinder 4 and the unloading cylinder 5 are arranged on the X direction of the platform 1, one end of them is fixed on the platform 1, and the other end (that is, the telescopic section) is relatively arranged, and the unloading cylinder 5 is arranged on the platform 1 Inside, the pusher cylinder 4 is arranged outside the stand 1 .

The function of the slope slideway is to guide the blank from the discharge inlet to the position of the chuck. It should be understood that any structure that can realize this function can be set as the slope slideway of the present invention. As a preferred structure of the present utility model, the shape of the slope slideway 2 is set as an L shape as shown in FIGS. 1 and 3 . The slope slideway 2 includes a sliding portion inclined downward along the X direction of the platform 1 , a docking portion parallel to the X direction of the platform 1 , and a transition portion connecting the sliding portion and the docking portion. The feeding cylinder 3 pushes the bottom of the sliding part to make the slope slide 2 translate along the Y direction of the platform 1, and the pushing cylinder 4 pushes the transition part to make the slope slide 2 translate along the X direction of the platform 1. To guide the blank to the collet 7. The above preferred structure of the slope slide of the utility model has the best matching effect with the cylinder, and the structure is the simplest. The entrance of the slope slideway 2 is used to put in blanks, and the outlet of the slope slideway 2 is aligned with the blanking cylinder 5 .

On the platform 1 between the blanking cylinder 5 and the outlet of the ramp slide 2, a chuck 7 is also fixedly arranged. The structure of the chuck belongs to common knowledge in this field. For example, you can refer to "Optimized Design of Spring Pneumatic Pipe Chuck, "Inner Mongolia Agricultural University", 2014, Zhao Qinghui", and will not repeat it here.

A feeding cylinder 3 is also fixedly arranged outside the platform 1 in the Y direction, and the feeding cylinder 3 is used to push the ramp slideway 2 to translate along the Y direction of the platform 1 . A material receiving cylinder 6 fixed to the stand 1 is also arranged below the material discharging cylinder 5 , and a material receiving tray 10 is connected to the material receiving cylinder 6 .

As a preferred structure of the present invention, a through hole 9 as shown in FIG. 1 can also be provided on the side of the transition portion of the slope slideway 2 opposite to the pushing cylinder 4 . When the pushing cylinder 4 stretches toward the slope slideway 2 and pushes the slope slideway 2 along the X direction, the front end of the telescopic rod of the pushing cylinder 4 is limited in the through hole 9, thereby facilitating the positioning of the pushing cylinder 4.

The working process of an automatic loading and unloading device of the utility model is as follows:

The feeding process is as follows: the blank in the silo enters the slope slide from the entrance of the slope slide by its own weight, and the feeding cylinder moves along the Y-axis to push the slope slide to translate along the Y-axis chuck direction, and sends the blank into the pusher. On the axis of the main shaft where the air cylinder and the blanking cylinder are located. The feeding cylinder stretches out to compress the disc spring, and the hole of the collet expands, waiting for the blank to enter. The telescopic rod of the pushing cylinder advances forward, pushing the slope slideway to translate along the X-axis chuck direction, so that the outlet of the slope slideway is aligned with the chuck hole, thereby pushing the blank into the collet hole. The feeding cylinder returns, the workpiece is clamped, and the feeding process is completed. The blanking mechanism is composed of a blanking mechanism and a receiving mechanism.

The blanking process is as follows: after the workpiece is processed, the blanking cylinder is stretched out, the disc spring is pressed down, the collet is released, the receiving cylinder moves to the bottom of the chuck, the workpiece is caught by the receiving tray, and the automatic blanking is completed process.

The complete automatic loading and unloading action sequence is: manual loading of the silo → feeding cylinder advance → feeding cylinder retreat → unloading cylinder advance → push cylinder advance → unloading cylinder retreat → workpiece clamping → push cylinder retreat → turning Processing→feeding cylinder enters→clamp loosens→feeding cylinder enters→workpiece pops out→feeding cylinder retracts→feeding cylinder retreats→cycle execution, the above automatic loading and unloading process can be designed by using SolidWorks software.
