Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a method for performing double-sided processing on difficult-to-adsorb parts by using a vacuum suction cup. Background Art

[0002] During the machining process, vacuum suction cups are mainly used for processing easily deformed plate parts. However, the adsorption force is small for parts that are difficult to adsorb and have many hollow parts. The parts are easy to loosen during machining, resulting in the scrapping of the parts. Moreover, only one side can be processed, which seriously affects the processing efficiency and quality of such parts. Summary of the invention

[0003] In view of this, the present invention provides a method for double-sided processing of difficult-to-adsorb parts using a vacuum suction cup. The double-sided group processing method using the vacuum suction cup can realize one-time processing of multiple pieces of difficult-to-adsorb parts on both sides using the vacuum suction cup, thereby expanding the range of parts processed by the vacuum suction cup and the processing efficiency. The processing method is simple and effective.

[0004] The technical solution of the present invention:

[0005] A method for double-sided processing of hard-to-absorb parts using a vacuum suction cup, the processing method comprising the following steps:

[0006] S101: Design the size of the blank for group processing of parts according to the size of the processed parts and the size of the vacuum suction cup;

[0007] S102: machining a positioning pin hole on the blank, adsorbing the blank on the suction cup based on the positioning of the positioning pin, and operating the CNC machine tool to complete the group processing of the first side of the part;

[0008] S103: removing the blank from the vacuum chuck, cleaning the first surface and pasting a layer of sticky tape or film on the first surface to make the tape or film adhere evenly;

[0009] S104: Based on the positioning of the positioning pin, the first surface after the tape or film is attached is adsorbed on the vacuum suction cup to complete the positioning and clamping of the second surface part processing;

[0010] S105: Operate the CNC machine tool to complete the second side processing of the part.

[0011] Furthermore, in the S101, the position and size of the positioning pin hole on the blank are designed to facilitate double-sided clamping and positioning of the blank.

[0012] Further, in S102, when processing the first surface of the blank, the portion of the first surface of the blank other than the part features is not processed in the depth direction.

[0013] Furthermore, in the S105, the process of operating the CNC machine tool to complete the second surface processing of the part also includes: removing the part other than the feature of the part by using the CNC machine tool.

[0014] Furthermore, when designing the blank, a plurality of groups of parts of the same specification arranged in an array are planned.

[0015] Furthermore, the parts are hollow parts.

[0016] Beneficial effects of the present invention:

[0017] The present invention proposes a method for performing double-sided processing by means of a vacuum suction cup for parts that are difficult to adsorb, and multiple pieces can be processed in groups at the same time. This method solves the problem that the parts are difficult to adsorb in their final state by leaving a margin for processing one side and then pasting a highly sticky tape or film. At the same time, the stickiness of the tape or film ensures that the parts are fixed after being separated from the material process handle, thereby realizing double-sided group processing.

[0033] S101: Designing the size of the blank 1 for group processing of the parts 4 according to the size of the processed parts 4 and the size of the vacuum suction cup 2;

[0034] S102: machining a positioning pin hole 11 on the blank 1, adsorbing the blank 1 on the suction cup based on the positioning of the positioning pin, and operating the CNC machine tool to complete the group processing of the first surface of the part 4;

[0035] S103: removing the blank 1 from the vacuum suction cup 2, cleaning the first surface and pasting a layer of adhesive tape 3 or film on the first surface, so that the tape 3 or film is pasted evenly;

[0036] S104: Based on the positioning of the positioning pin, the first surface after the tape 3 or the film is attached is adsorbed on the vacuum suction cup 2 to complete the positioning and clamping of the second surface part 4;

[0037] S105: Operate the CNC machine tool to complete the second surface processing of part 4.

[0038] In this embodiment, in S101, the position and size of the positioning pin hole 11 on the blank 1 are also designed to facilitate double-sided clamping and positioning of the blank 1.

[0039] In this embodiment, in S102 , when processing the first surface of the blank 1 , the portion of the first surface of the blank 1 other than the features of the part 4 is not processed in the depth direction.

[0040] In this embodiment, in S105, the process of operating the CNC machine tool to complete the second surface processing of the part 4 also includes: removing the part other than the feature of the part 4 by using the CNC machine tool.

[0041] In this embodiment, the blank 1 is designed to have multiple groups of parts 4 of the same specifications arranged in an array;

[0042] In this embodiment, the part 4 is a hollow part 4.

[0043] See also Figure 1-Figure 7 , this embodiment can be described based on the following steps:

[0044] 1. Design the size of the blank 1 and the locating pin hole 11 for group processing of the parts 4 according to the size of the parts 4 to be processed and the size of the vacuum suction cup 2.

[0045] 2. Process the positioning pin hole 11 on the material, use the positioning pin to position the material on the suction cup, operate the CNC machine tool to complete the group processing of the first side of part 4, and do not process the depth direction of the upper surface of part 4 except for the features of part 4 for the subsequent third step operation. Leave a certain margin in the depth direction of part 4 to avoid milling through (Note: the margin value is determined according to the features of part 4 on the second side).

[0046] 3. Remove the material from the vacuum suction cup 2, deburr the first side, clean it, and stick a layer of highly sticky tape 3 or film on the first side to ensure that the tape 3 or film is pasted flat (Note: The bonding force between the tape 3 or film and the part 4 should be as large as possible to ensure that the part 4 slides after being separated from the blank).

[0047] 4. Use the positioning pin to adsorb the first side after the tape 3 or film is pasted on the vacuum suction cup 2 to complete the positioning and clamping of the second side part 4 processing.

[0048] 5. Operate the CNC machine tool to complete the group processing of the second side of part 4, directly process part 4 into shape, and complete the one-time processing of multiple difficult-to-adsorb parts 4.

The adsorption area of ​​the vacuum suction cup 2 is small, and part 4 is easy to loosen during processing.

[0051] Step 1: Design the size of the blank 1 and the positioning pin hole 11 for group processing of the parts 4 according to the size of the parts 4 to be processed and the size of the vacuum suction cup 2. The size of the blank 1 is designed to be 7mm×400mm×450mm, and the pin hole diameter is 6mm. One blank 1 can process four parts 4. Figure 2 shown.

[0052] Step 2: Process the positioning pin hole 11 on the material, and use the positioning pin to position the material on the suction cup. The clamping diagram is as shown in the figure Figure 3 As shown; operate the CNC machine tool to complete the group processing of the first side of part 4, and the depth direction of part 4 is processed by 2.7mm. After the first side is processed, the state is as follows Figure 4 shown.

[0053] Step 3: Remove the material from the vacuum suction cup 2, remove the burrs on the first side, clean it, and stick a layer of adhesive tape 3 or film on the first side to ensure that the tape 3 or film is pasted flat. Figure 5 shown.

[0054] Step 4: Use the positioning pins to position the first side after the tape 3 or film is attached to the vacuum suction cup 2 to complete the positioning and clamping of the second side part 4. The clamping state is as follows: Figure 6 shown.

[0055] Step 5: Operate the CNC machine tool to complete the second side group processing of part 4, and directly process part 4 into shape. The final state of part 4 after processing is as follows Figure 7 As shown, the processing of four difficult-to-adsorb parts 4 is completed at one time.
