DETAILED DESCRIPTION

[0028] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein.

[0029] As Figures 1 to 4 shown, an automatic feeding and pressing device is provided, comprising a positioning unit 1, a pressing unit 2, and a feeding mechanism 3. The positioning unit 1 comprises a base 11 and two positioning pieces 12 fixed to the base 11. The two positioning pieces 12 are symmetrically arranged on both sides of the pressing unit 2. The feeding mechanism 3 is arranged above the positioning unit 1 and is used to clamp and place the parts to be machined on the positioning pieces 12.

[0030] The positioning unit 1 of the present application comprises two positioning pieces 12, which can simultaneously accommodate two parts to be machined for numerical control machining. The pressing unit 2 is designed between the two positioning pieces 12. After the parts are placed in position, the pressing unit 2 can automatically rotate and descend, simultaneously pressing and fixing the parts to be machined, replacing the manual operation of placing and fixing the parts to be machined. The feeding mechanism 3 is arranged above the positioning unit 1, which can automatically clamp and place the parts to be machined prepared in advance on the positioning pieces 12, realizing automatic feeding of the integrated numerical control equipment. The present application replaces the manual feeding and fixing method, saves the time for placing and fixing the parts to be machined, and improves the machining efficiency and output of the integrated numerical control equipment.

[0031] As Figure 2 shown, the positioning piece 12 is provided with an inner recessed positioning part 121, which is engaged with the outer periphery of the part to be machined. The part to be machined is limited to move in the positioning part 121, and cooperates with the pressing unit 2 to realize the positioning and pressing of the part. The bottom surface of the inner recessed positioning part 121 is in contact with the bottom surface of the part to be machined, and there is a suitable distance space between the top surface of the positioning part 121 and the top surface of the part to be machined, so as to provide a space for the feeding mechanism 3 to clamp and place.

[0032] As Figure 2As shown, the pressing unit 2 includes a pressing drive 21 and a pressing arm 22 connected to the pressing drive 21. The pressing drive 21 can drive the pressing arm 22 to rotate back and forth and lift and lower. The middle of the pressing arm 22 is connected to the output end of the pressing drive 21. The two ends of the pressing arm 22 are provided with a pressing head 23, which is threadedly connected to the pressing arm 22.

After the loading mechanism 3 places the parts to be processed on the positioning members 12, the pressing drive 21 drives the pressing arm 22 to rotate 90 degrees, so that the pressing heads 23 at both ends of the pressing arm 22 are aligned with the two positioning members 12, and then drives the pressing arm 22 to move downward to press the parts to be processed. The bottom of the pressing head 23 that contacts the parts to be processed can be made of elastic material to avoid crushing the parts to be processed. The pressure head 23 and the pressure arm 22 are connected by a threaded connection, which makes it easy to adjust the height of the pressure head 23 according to the parts to increase compatibility; at the same time, it is easy to disassemble and replace the pressure head 23.

The transverse movement unit 32 controls movement between the gripping position and the placement position, the lifting unit 33 controls the lifting movement, and the gripping unit 34 controls the gripping and placement of parts. These three groups of drive units are controlled in a coordinated manner by a control program, thereby realizing the function of automatic gripping and loading.

[0034] like Figure 3 and Figure 4 As shown, the feeding mechanism 3 also includes an L-shaped first connecting plate 35 and a second connecting plate 36. The first connecting plate 35 includes a horizontal portion 351 and a vertical portion 352. The horizontal portion 351 is connected to the output end of the lifting unit 33, and one side of the vertical portion 352 is close to the surface of the lifting unit 33.

The gripping unit 34 is fixed to the second connecting plate. The first and second connecting plates 35, 36 realize the control of the lateral movement and elevation of the gripping unit 34.

[0035] like Figure 3 and Figure 4 As shown, two feeding mechanisms 3 are provided, and the two feeding mechanisms 3 are respectively used to clamp the parts to be processed and place them on the corresponding positioning members 12. By synchronously controlling the two feeding mechanisms 3, synchronous feeding of the two positioning members 12 is achieved.
