Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, in particular to a vacuum suction cup tooling for lathe processing. Background Art

[0002] The traditional clamp-type workpiece fixing method has flexible workpiece clamping and easy clamp disassembly, but the positioning accuracy of the workpiece is not high and it has great restrictions on the workpiece itself. It is only suitable for clamping workpieces with regular shapes. For some thin-walled shell parts, the walls are thin and the rigidity is poor, which are easy to deform during processing. Due to the structural characteristics of such parts, their appearance is an overall slope structure. If the traditional three-jaw chuck is used to clamp the workpiece, there is no space for clamping. If the reverse tightening method of screws is used, it is time-consuming and labor-intensive, and the production efficiency is low, which is not suitable for batch processing.

[0003] Therefore, it is urgent to design a vacuum suction cup tooling for lathe processing, which can quickly clamp and position thin-walled shell parts and reduce the processing deformation of parts. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a vacuum suction cup tooling for lathe processing, which is convenient for clamping and positioning of workpieces, reduces the influence of clamping force on deformation of workpieces, and improves production efficiency and machining quality stability.

[0005] The utility model solves the technical problem by adopting the following technical solutions:

[0006] A vacuum suction cup tool for lathe processing, characterized in that it comprises:

[0007] A vacuum suction cup body and a quick-insert connector, wherein the vacuum suction cup body comprises a supporting portion and a clamping portion, wherein both the clamping portion and the supporting portion are cylindrical, wherein the upper surface of the clamping portion is integrally connected to the supporting portion, wherein an annular air passage is provided in the supporting portion, wherein sealing plugs are respectively installed at both end surfaces of the annular air passage, wherein an adsorption chamber is passed through the upper portion of the annular air passage, wherein the adsorption chamber is connected to the supporting bottom surface of the supporting portion;

[0008] A cylindrical air duct is vertically opened at the center of the clamping part, the top of the cylindrical air duct is connected with the annular air duct, and a quick-connect connector is installed at the bottom of the cylindrical air duct, which is connected to the cylindrical air duct and the annular air duct inside the vacuum suction cup body.

[0009] Moreover, the material of the vacuum chuck body is brass H62.

[0010] Moreover, the cross-sectional area of ​​the clamping portion is smaller than the cross-sectional area of ​​the supporting portion.

[0011] Moreover, the adsorption chamber is in a circular ring shape, and a sealing rubber pad is installed on the adsorption chamber.

[0012] Furthermore, a support limiting end surface is also arranged on the support bottom surface.

[0013] The advantages and positive effects of the utility model are:

[0014] The utility model provides a vacuum air source by connecting an external vacuum pump air source air pipe through a quick-insert connector. After the vacuum air source is connected, the parts are tightly adsorbed and fixed by using the principle of atmospheric pressure difference. Since the clamping force of the vacuum suction cup is uniform and stable, the clamping deformation of the parts will not be caused, thereby realizing rapid clamping and positioning of the parts.

[0015] The utility model realizes a vacuum suction cup tooling for lathe processing. The whole equipment has a simple and compact structure and low manufacturing cost. It realizes the rapid clamping and positioning of parts, reduces the deformation influence of the clamping force on the workpiece, and improves the production efficiency and the stability of machining quality.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely descriptive and not restrictive, and the protection scope of the present invention cannot be limited thereto.

[0022] A vacuum suction cup tooling for lathe processing, comprising:

[0023] The vacuum suction cup body and the quick-insert connector 6, the vacuum suction cup body includes a supporting portion 3 and a clamping portion 5, the clamping portion 5 and the supporting portion 3 are both cylindrical, the upper surface of the clamping portion 5 is integrally connected to the supporting portion 3, an annular air duct 10 is provided in the supporting portion 3, and sealing plugs 4 are respectively installed on both end surfaces of the annular air duct 10 for closing the air duct, an adsorption chamber 9 passes through the upper portion of the annular air duct 10, the adsorption chamber 9 is connected to the supporting bottom surface 8 of the supporting portion 3, and the supporting bottom surface 8 is clamped with a part 2; after the adsorption chamber 9 is connected to the vacuum air source, the principle of atmospheric pressure difference is used to tightly adsorb and fix the part 2, and because the clamping force of the vacuum suction cup is uniform and stable, it will not cause the clamping deformation of the part 2, thereby realizing the rapid clamping and positioning of the part 2.

[0024] A cylindrical air passage 11 is vertically opened at the center of the clamping portion 5, the top of the cylindrical air passage 11 is connected to the annular air passage 10, and a quick-connect connector 6 is installed at the bottom of the cylindrical air passage 11. The quick-connect connector 6 is connected to the cylindrical air passage 11 and the annular air passage 10 inside the vacuum suction cup body, and is externally connected to the vacuum pump air source pipe to provide a vacuum air source. The entire vacuum suction cup body is fixed on the three-jaw chuck of the lathe through the clamping portion 5 for subsequent lathe processing.

[0025] The material of the vacuum chuck body is brass H62.

[0026] The cross-sectional area of ​​the clamping portion 5 is smaller than the cross-sectional area of ​​the supporting portion 3 .

[0027] The adsorption chamber 9 is annular, and a sealing rubber pad 7 is installed on the adsorption chamber 9. Since the center of the component 2 is a through-hole structure, the sealing rubber pad 7 is used to seal and isolate the adsorption chamber 9 from the component 2, thereby meeting the airtightness requirement.

[0028] The support bottom surface 8 is also provided with a support limit end surface 1 , and the support limit end surface 1 is connected to the outer edge of the part 2 to achieve positioning support for the part 2 .

[0029] Working principle:

[0030] When processing parts, first stop the external vacuum air source of the quick-plug connector, load the parts into the vacuum suction cup body, and then connect the external vacuum air source of the quick-plug connector, and the parts are fixed by vacuum adsorption; after the lathe completes the inner cavity size of the parts, stop the external vacuum air source of the quick-plug connector again, remove the parts, and complete a single processing process.

[0031] This reciprocating cycle process realizes the rapid clamping and positioning of parts, thereby reducing the influence of clamping force on workpiece deformation, greatly improving production efficiency, ensuring product quality, and realizing batch processing.
