Description

Technical Field

[0001] This application relates to the field of clamping and processing technology for small-sized thin-walled materials, and in particular to a vacuum suction cup device. Background Technology

[0002] Standard vacuum chucks have poor adaptability to parts of different sizes and irregular shapes, lacking versatility. They often require different conversion discs to be designed for different workpieces, increasing production costs and preparation time. Existing standard chucks have a hole diameter of φ12mm and a hole center distance of 18mm. While the chuck can achieve adsorption when machining parts larger than 12mm, it cannot completely adsorb irregularly sized parts with local dimensions smaller than 12mm. When machining thin-walled, brittle materials, it is prone to breakage or fragmentation. Utility Model Content

The second adsorption holes that are alternately arranged with the first adsorption holes are adapter adsorption holes. The connecting groove is formed on the adapter plate to conduct the adapter adsorption holes and the first adsorption holes.

[0012] In one feasible implementation, the groove depth of the connecting groove is 0.15 mm to 0.3 mm; and / or

[0013] The width of the connecting groove is 3mm to 5mm.

[0014] In one feasible implementation, the vacuum suction cup device further includes:

[0015] The area formed by the arrangement of multiple connecting holes and multiple second adsorption holes is the workpiece adsorption area.

[0038] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided by this invention. However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.

[0039] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0040] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0041] like Figures 1 to 5 As shown in the figure, this application embodiment proposes a vacuum suction cup device, including: a vacuum suction cup body 110, on which a plurality of first suction holes 111 and first assembly holes 112 are formed; an adapter plate 120, on which a plurality of second suction holes 121 and second assembly holes 122 are formed, the adapter plate 120 being used to connect to the vacuum suction cup body 110 through the first assembly holes 112 and the second assembly holes 122; wherein, the aperture of the first suction holes 111 is different from the aperture of the second suction holes 121.

[0042] The vacuum suction cup device provided in this application embodiment includes a vacuum suction cup body 110 and an adapter plate 120. A first suction hole 111 is formed on the vacuum suction cup body 110, and a second suction hole 121 is formed on the adapter plate 120. The adapter plate 120 can be connected to the vacuum suction cup body 110 through a first mounting hole 112 and a second mounting hole 122. When adsorbing tools, it can provide a negative pressure environment for the vacuum suction cup body 110. The vacuum system body can adsorb the workpiece through the first suction hole 111. When the aperture of the first suction hole 111 does not match the workpiece specifications, the adapter plate 120 can be assembled onto the vacuum suction cup body, which also provides a negative pressure environment for the vacuum suction cup body 110. The negative pressure acts on the second suction hole 121 of the adapter plate 120 through the first suction hole 111, and the workpiece can be adsorbed through the second suction hole 121. This increases the versatility of the vacuum suction cup device and can ensure the reliability of workpiece adsorption.

[0043] In one feasible implementation, the diameter of the first adsorption hole 111 is the standard suction cup diameter, which is 10 to 14 mm, and the diameter of the second adsorption hole 121 is smaller than that of the first adsorption hole 111.

[0044] In this technical solution, the specifications of the first adsorption hole 111 and the second adsorption hole 121 are further provided. The diameter of the first adsorption hole 111 can be the diameter of a standard suction cup, such as 12mm. However, considering the actual use scenario, it is difficult for the first adsorption hole 111 to adsorb small parts. Therefore, the diameter of the second adsorption hole 121 can be smaller than the diameter of the first adsorption hole 111. For example, the diameter of the second adsorption hole 121 can be 3mm to 8mm, preferably 4mm. Based on this, the second adsorption hole 121 can better adsorb smaller workpieces, which can avoid damage to the workpiece due to improper adsorption and ensure the yield rate.

[0045] like Figure 4 As shown, in one feasible embodiment, the adapter plate 120 further includes a connecting groove 123. When the adapter plate 120 is connected to the vacuum suction cup body 110, a plurality of second suction holes 121 are arranged opposite to the first suction holes 111 on the vacuum suction cup body 110, and another portion of the second suction holes 121 are alternately arranged with the first suction holes 111 on the vacuum suction cup body 110. The second suction holes 121 that are alternately arranged with a suction hole are the adapter suction holes. The connecting groove 123 is opened on the adapter plate 120 to conduct the adapter suction holes and the first suction holes 111.

[0046] In this technical solution, considering the difference in aperture between the second adsorption hole 121 and the first adsorption hole 111, when the adapter plate 120 is connected to the vacuum suction cup body 110, some of the second adsorption holes 121 may be staggered with the first adsorption holes 111 on the vacuum suction cup body 110. In this case, these second adsorption holes 121 can be defined as adapter adsorption holes. For the adapter adsorption holes, a connecting groove 123 that communicates with the second adsorption holes 121 can be provided on the adapter plate 120. When the adapter plate 120 is connected to the vacuum suction cup body 110, the connecting groove 123 can communicate with the second adsorption holes 121 and the first adsorption holes 111, so that the negative pressure of the first adsorption hole 111 can act on the second adsorption hole 121, and the workpiece can be better adsorbed.

[0047] In one feasible implementation, the groove depth of the connecting groove 123 is 0.15 mm to 0.3 mm; and / or the groove width of the connecting groove 123 is 3 mm to 5 mm.

[0048] In this technical solution, the specifications of the connecting groove 123 are further provided. The groove depth of the connecting groove 123 is 0.15mm to 0.3mm, and the groove width of the connecting groove 123 is 3mm to 5mm. Preferably, the groove depth of the connecting groove 123 is 0.2mm and the groove width of the connecting groove 123 is 4mm. This setting ensures that the first adsorption hole 111 can communicate with the second adsorption hole 121, while avoiding the connecting groove 123 occupying too much of the thickness of the adapter plate 120, which facilitates the control of the thickness of the adapter plate 120 and facilitates the assembly of the adapter plate 120 onto the vacuum suction cup body 110.

[0049] In one feasible embodiment, the vacuum suction cup device further includes: a plurality of connecting holes 130, a workpiece adsorption area formed by a plurality of second adsorption holes 121 arranged in a manner, and a plurality of connecting holes 130 distributed on the periphery of the workpiece adsorption area, for connecting to the first adsorption hole 111 of the lead screw of the vacuum suction cup body 110.

[0050] In this technical solution, the adapter plate 120 can also be formed with multiple connecting holes 130. The multiple connecting holes 130 are distributed around the workpiece adsorption area formed by multiple second adsorption holes 121. When the adapter plate 120 is assembled on the vacuum suction cup body 110, the fixing of the adapter plate 120 can be more reliable.

[0051] In one possible implementation, the thickness of the adapter plate 120 is 2.5 mm to 4 mm; and / or the adapter plate 120 is made of aluminum; and / or the size of the adapter plate 120 is smaller than that of the vacuum suction cup body 110.

[0052] In this technical solution, a design for the adapter plate 120 is further provided. The thickness of the adapter plate 120 can be 2.5mm to 4mm, preferably 3mm, and it is made of aluminum. This allows the adapter plate 120 to be thinner and easier to assemble onto the vacuum suction cup body 110. The size of the adapter plate 120 is smaller than that of the vacuum suction cup body 110, thus preventing the adapter plate 120 from taking up excessive space in the vacuum suction cup body 110.

[0053] Understandably, the 120 adapter board, with its 3mm thickness, is relatively thin, making it particularly suitable for installation and use in equipment with limited space.

[0054] like Figure 3 As shown, in one feasible embodiment, the vacuum suction cup device further includes a contouring portion 140, which is formed on the side of the adapter plate 120 opposite to the vacuum suction cup body 110. The contouring portion 140 is adapted to the shape of the part to be processed or the processing technology. With this configuration, the contouring portion 140 makes the adsorption of the workpiece to the adapter plate 120 more reliable, further reducing damage to the workpiece due to adsorption transfer and ensuring a high yield rate.

[0055] like Figure 3 As shown, in one possible embodiment, the contouring part 140 includes: a positioning groove 141 formed around the periphery of a plurality of second adsorption holes 121; and / or a clearance hole 142 formed on the adapter plate 120.

[0056] In this technical solution, a contouring part 140 is further provided. The contouring part 140 may include a positioning groove 141 and a clearance hole 142. Based on this, the positioning groove 141 allows the workpiece to be pre-positioned when it is adsorbed by the adapter plate 120, making the adsorption of the workpiece more reliable. The clearance hole 142 allows the workpiece to be avoided at the machining location during grinding or milling, making the machining process smoother.

[0057] like Figure 2 and Figure 3 As shown, in one feasible embodiment, there are multiple first mounting holes 112 and second mounting holes 122. This arrangement makes the connection between the adapter plate 120 and the vacuum suction cup body 110 more reliable.

[0058] In some examples, both the first mounting hole 112 and the second mounting hole 122 can be threaded holes, and the adapter plate 120 can be fixed to the vacuum suction cup body 110 by screws.

[0059] In one feasible implementation, there are multiple adapter plates 120, and the diameters of the second suction holes 121 on the multiple adapter plates 120 are different. This arrangement allows for the selective selection of adapter plates 120 based on different components, further increasing the applicability of the vacuum suction cup device.
