Manual clamping of single parts has several drawbacks: the small size of the parts makes clamping difficult, time-consuming, labor-intensive, and prone to worker fatigue; manual clamping is inefficient; and improper clamping can damage the product. Therefore, solving the clamping problem is of paramount importance for the processing of small die-cast parts. Summary of the Invention

[0051] In this invention, the positioning fixture includes a positioning base 8, a plurality of positioning slots disposed on the positioning base 8, a rotating block 11 disposed within the positioning slots, and a first spring 13. The positioning slots are used to accommodate the product to be processed. A rotating shaft 12 is disposed through the rotating block 11, and the rotating shaft 12 is the rotation center of the rotating block 11, supporting the rotation of the rotating block 11. Under the elastic force of the first spring 13, the rotating block 11 rotates around the rotating shaft 12 to laterally push and place the product to be processed within the positioning slot.

[0052] In this invention, the CNC automated machining equipment for small die-cast parts further includes an inclined top mechanism, wherein the inclined top mechanism cooperates with the rotating block to position the product to be processed into the positioning groove, and to place the processed product and the positioning groove in a gap state.

The inclined top plate 10 is located below the positioning base 8. The fourth dual-axis cylinder 9 pushes the inclined top plate 10 to the right, and the inclined top plate 10 pushes the rotating block 11 to rotate counterclockwise around the rotating shaft 12. A gap is formed between the rotating block 11 and the side wall of the positioning groove of the positioning base 8, through which the product to be processed enters the positioning groove. The fourth dual-axis cylinder 9 pushes the inclined top plate 10 to the left, and the rotating block 11, under the elastic force of the first spring 13, rotates clockwise around the rotating shaft 12, pressing and positioning the product to be processed in the positioning groove.

[0054] In this invention, the floating cover plate assembly 1 includes an upper cover plate 17, a lower cover plate 18, a second spring 19 located between the upper cover plate 17 and the lower cover plate 18, and a pressure block 20; wherein, a plurality of through slots are correspondingly provided on the upper cover plate 17 and the lower cover plate 18, each pressure block 20 is correspondingly disposed in each through slot, and each pressure block 20 is correspondingly fitted with a second spring 19, the pressure block 20 moves in the through slot under the action of the second spring 19, wherein the pressure block 20 is used to press the product to be processed in the positioning slot.

[0055] exist Figure 8 In the embodiment shown, the floating cover plate assembly 1 uses screws to combine the upper cover plate 17 and the lower cover plate 18 together to form a floating pressure holding mechanism, which achieves the pressing of each product when processing the product to be processed on the positioning fixture.

[0056] In this invention, the floating cover assembly pick-and-place device includes a first dual-axis cylinder 3 and a second dual-axis cylinder 4 connected to the CNC spindle. Electromagnets 14 are provided at the top of both the first dual-axis cylinder 3 and the second dual-axis cylinder 4. Under the control of the CNC spindle, the first dual-axis cylinder 3 and the second dual-axis cylinder 4 drive the corresponding electromagnets 14 to attract the floating cover assembly 1 onto the positioning fixture, and press the pressure block 20 against the product to be processed in the positioning groove; and the first dual-axis cylinder 3 and the second dual-axis cylinder 4 drive the corresponding electromagnets 14 to remove the processed floating cover assembly 1 from the positioning fixture. Figure 6 As can be seen in the illustrated embodiment, the electromagnet 14 is positioned at the top of either the first dual-axis cylinder 3 or the second dual-axis cylinder 4. That is, the first dual-axis cylinder 3 and the second dual-axis cylinder 4 are respectively used in conjunction with the electromagnet 14 to clamp the floating cover assembly; the electromagnet 14 achieves the attraction and release of the floating cover assembly through the magnetization and demagnetization controlled by the PLC program.

[0057] In this invention, the CNC automated machining equipment for small die-cast parts further includes a base plate 15, rotary cylinders 16 disposed on both sides of the base plate 15, and a cover plate placement platform 2. The base plate 15 supports the positioning fixture and the inclined lifting mechanism. The rotary cylinders 16 apply a Y-axis clamping force to the floating cover plate assembly 1 and the positioning fixture.

[0058] The cover plate placement platform 2 is used to place the floating cover plate assembly 1. Before loading and unloading, the floating cover plate assembly 1 is placed on the cover plate placement platform 2 without affecting the normal loading and unloading of products.

[0059] The specific processing procedure of the CNC automated machining equipment for small die-cast parts provided by this invention includes five steps: loading, placing the floating cover plate assembly, machining, removing the floating cover plate assembly, and unloading. Details are as follows:

[0060] Loading process: Structures in the loading state, such as Figure 3 As shown, the floating cover assembly 1 is placed on the cover placement platform 2. The first dual-axis cylinder 3 and the second dual-axis cylinder 4 connected to both sides of the main shaft are in the retracted state, while the third dual-axis cylinder 5 connected in the middle is in the extended state. Four suction cups 6 are connected to the third dual-axis cylinder 5. Controlled by the PLC program, the suction cups 6 are used to pick up the products to be processed from the material tray 7 placed on the four axes and transport them to the positioning base 8 in the positioning fixture. At this time, the fourth dual-axis cylinder 9 installed on the left side of the three-axis worktable is in the extended state, driving the inclined top plate 10 used for loading to move to the right, pushing the rotating block 11 in the positioning fixture to rotate counterclockwise around the rotating shaft 12, so that a certain gap is formed between the rotating block 11 and the side wall of the positioning base, and the product can be smoothly loaded into the positioning slot. Figure 4 As shown. After all products in the tray are loaded into the fixture, the dual-axis cylinder 9 is retracted, and the inclined top plate is moved to the left. Under the action of the spring force of the spring 13, the rotating block rotates clockwise around the rotating shaft, pressing the products. The third dual-axis cylinder 5 is then retracted, and the suction cup 6 is returned to a position that does not affect processing. At this point, the loading steps are all completed.

[0061] The process of installing the floating cover assembly: At this time, if Figure 7 As shown, the third dual-axis cylinder 5 is in the retracted state, controlling the extension of the first dual-axis cylinder 3 and the second dual-axis cylinder 4, and controlling the electromagnets 14 at the top of the first dual-axis cylinder 3 and the second dual-axis cylinder 4 to be magnetized. Driven by the main shaft, the first dual-axis cylinder 3 and the second dual-axis cylinder 4 use the electromagnets 14 installed at their tops to pick up the magnetic floating cover assembly placed on the cover plate placement platform 2 and place it on the positioning base 8, pressing the product down. The four rotating pressing cylinders 16 installed on both sides of the base plate 15 are controlled to retract, pressing the floating cover assembly 1 tightly.

[0062] Processing steps: During processing, due to the large number of products to be processed, each product may have inconsistent heights. Therefore, each slot held by the floating cover assembly is made to be floating. For example... Figure 8 As shown, each pressure block 20 is installed in the cavity formed by the upper cover plate 17 and the lower cover plate 18. After the second spring 19 is installed, each pressure block 20 can slide up and down, so that the product in each slot can be completely pressed.

[0063] The floating cover assembly removal process: After processing, as follows... Figure 9 As shown, the rotary cylinder 16 is in the extended state, and the first dual-axis cylinder 3 and the second dual-axis cylinder 4 are in the extended state. This process is exactly the opposite of the process of placing the floating cover plate assembly, but the working principle is the same. The movement of the main shaft drives the first dual-axis cylinder 3 and the second dual-axis cylinder 4 in the extended state, as well as the electromagnet 14 controlled by the PLC system, to pick up the floating cover plate assembly located on the positioning base 8 and place it on the cover plate placement platform 2.

[0064] Material handling process: Control the first dual-axis cylinder 3 and the second dual-axis cylinder 4 to be in the retracted state, the third dual-axis cylinder 5 to be in the telescopic state, and the fourth dual-axis cylinder 9 on the side to be in the extended state. Move the rotating block 11 to make it form a certain gap with the processed product. Under the drive of the third dual-axis cylinder 5, the suction cup 6 transfers the processed product from the positioning base to the material tray 7.

[0065] As can be seen from the above embodiments, the CNC automated machining equipment for small die-cast parts provided by the present invention, in which the floating cover plate assembly, positioning fixture, material handling assembly, floating cover plate assembly handling device, and CNC machine tool cooperate with each other to achieve automated machining. The spindle drives the movement of the suction cup to realize the loading and unloading of products; the spindle drives the movement of the electromagnet to realize the handling of the cover plate; the floating pressure of the cover plate realizes the clamping of products in each cavity; and the positioning fixture and rotating mechanism realize the side-pushing clamping of products. The entire machining process requires no operator intervention. The switching action of the cylinder, the electromagnet handling of the cover plate assembly, and the automatic loading and unloading of the suction cup are all controlled by the PLC program, thereby solving the problems of high clamping difficulty, time-consuming and labor-intensive clamping, easy worker fatigue, low clamping efficiency, and easy damage to products in the current machining of small die-cast parts.
