When the workpiece 8 between the two sets of clamping blocks 61 is pushed out by the subsequent workpiece 8, the pushed workpiece 8 moves onto the inclined rack 7 and slides away from the positioning block 3 along the inclined direction of the inclined rack 7, thereby facilitating the collection of the workpiece 8.
The implementation principle of the embodiment is as follows: in the drilling process, the workpieces 8 are sequentially placed into the material cylinder 42, and the workpiece 8 on the lowest side of the material cylinder 42 is the machined workpiece 8; under the action of the gravity of the workpieces 8, the first group of workpieces 8 at the lowest side fall onto the workbench 1, and at the moment, the push rod 52 is driven by the air cylinder 51 to move, so that the first group of workpieces 8 on the workbench 1 are pushed into the transverse through hole 31.
Then, the air cylinder 51 is retracted and extended again, so that the second group of workpieces 8 falling from the barrel 42 is pushed into the transverse through hole 31, and the second group of workpieces 8 pushes the first group of workpieces 8 out of the transverse through hole 31; the first group of workpieces 8 will move against the two groups of guide surfaces 611 and urge the two groups of clamping blocks 61 away from each other; when the first group of workpieces 8 are located between the two groups of clamping blocks 61, the two groups of second springs 63 urge the corresponding clamping blocks 61 to abut against the side walls of the workpieces 8, and at this time, the first group of workpieces 8 are clamped and fixed, so that the first group of workpieces 8 and the push rod 52 can be clamped together on the second group of workpieces 8 in the transverse through hole 31.
In the process that the second group of workpieces 8 are pushed into the transverse through hole 31, the pushing surface 531 will abut against the abutting column 34 and urge the abutting column 34 to approach the workpieces 8 in the transverse through hole 31; when the second group of workpieces 8 are completely pushed into the transverse through hole 31, the pushing surface 531 abuts against the abutting column 34, and the elastic block 35 is urged to abut against the side wall of the workpiece 8 in the transverse through hole 31, so that the workpiece 8 is not easy to shake in the drilling process.
When the second group of workpieces 8 are drilled, the air cylinder 51 is retracted and extended again, and the push rod 52 pushes the third group of workpieces 8 falling from the material cylinder 42 into the transverse through hole 31; at this time, the third group of workpieces 8 will push the second group of workpieces 8 to be separated from the transverse through hole 31, so that the second group of workpieces 8 is clamped by the two groups of clamping blocks 61, and the second group of workpieces 8 will push the first group of workpieces 8 to be separated from the clamping blocks 61, so that the first group of workpieces 8 slide along the inclined direction of the inclined frame 7. The operation is repeated continuously, so that the full-automatic loading and unloading and drilling of the workpiece 8 can be realized, and the drilling efficiency of the workpiece 8 is greatly improved.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
