Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of numerical control machining, in particular to a double-station high-efficiency numerical control machining machine. BACKGROUND

[0002] A numerical control machine tool is an automatic machine tool equipped with a computer numerical control system, which accurately controls the movement, speed, position and machining process of the machine tool through digital instructions to achieve efficient and high-precision machining of complex parts. However, in practical applications, there are still some defects in numerical control machine tool machining: (1) When the existing numerical control machine tool processes workpieces, the mechanical hand usually grabs the material from the storage bin to the numerical control machine tool for processing. However, when the material in the tray is all processed, the tray needs to be pulled out of the storage bin and manually reloaded. The manual reloading link in this cycle forces the production line to stop and wait, and the production line must wait for the tray to be ready before it can continue to operate. This process becomes a bottleneck that restricts the overall production efficiency; (2) In order to improve the grabbing efficiency, multiple clamps are usually provided on the mechanical hand, which can clamp multiple workpieces. These clamps usually use rotary cylinders for position exchange. However, due to the mechanical structure gap of the rotary cylinder, the compressibility of the pneumatic system and other problems, the repeatability of the rotary cylinder is limited, and it is difficult to achieve high-precision arbitrary angle positioning, which makes it difficult for the clamp to rotate to the specified position for clamping.

[0037] As shown in Figures 3 to 5 to realize the alternate feeding function of the double material discs 2, the first moving unit 3 specifically comprises two groups of first guide rails 31 installed on the storage bin 1, each group of first guide rails 31 is slidably connected with a first sliding block 32, and the first sliding block 32 of each group of first guide rails 31 is provided with a moving frame 33, and the two material discs 2 are correspondingly placed on the two moving frames 33, the moving frame 33 and the material disc 2 can move back and forth along the first guide rail 31, when one of the material discs 2 is exhausted, the staff pulls out the material disc 2 through the moving frame 33 for preparation; Preferably, each group of the first guide rails 31 in the embodiment has a plurality of guide rail stations, the number of which can be determined according to the size of the moving frame 33, and the embodiment preferably adopts two guide rail stations as a group, which are arranged on both sides of the bottom of the moving frame 33 to ensure the stable movement of the moving frame 33.

[0038] Meanwhile, the tray 2 is provided with a plurality of storage openings 24 for placing workpieces 100, which are arranged in an array. In order to facilitate the grabbing of the manipulator 6, the moving frame 33 of the embodiment is further connected with a driving mechanism 34, which can drive the moving frame 33 to move forward and backward when one row of workpieces 100 on the tray 2 is exhausted, so that the next row of workpieces 100 moves to the grabbing position of the manipulator 6.
