Description

Technical Field

[0001] This utility model relates to the field of vacuum pneumatic clamp technology, specifically a vacuum suction cup pneumatic clamp. Background Technology

[0002] In existing technologies, the machining of ordinary workpieces requires the use of fixtures for clamping, and then the use of cutting tools to machine the parts of the workpiece outside the clamping part. The number of fixtures designed can vary depending on the size of the area to be machined. Usually, the entire surface of the workpiece is machined. The installation and clamping of the workpiece on the fixture is an important factor affecting the machining accuracy. Furthermore, after being clamped by commonly used fixtures, some sides will be obstructed to some extent, affecting the machining. At the same time, there will be situations where it is not compatible with the clamping and fixing of workpieces of different sizes. Therefore, there is an urgent need to provide a vacuum suction cup pneumatic fixture. Utility Model Content

[0003] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0004] Therefore, the purpose of this utility model is to provide a vacuum suction cup pneumatic clamp, in which the external negative pressure end acts on the negative pressure hole through the connecting pipe and the branch pipe, and the equally spaced branch pipes can ensure that the negative pressure is evenly applied to the negative pressure hole, so that the negative pressure generated at the negative pressure hole is in a balanced state, making the workpiece body more firmly fixed, reducing the deformation of thin plate parts, effectively ensuring the processing quality, and improving the production efficiency.

[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0006] A vacuum suction cup pneumatic clamp, comprising:

[0007] As a connecting plate for connecting substrates, the connecting plate has multiple sets of negative pressure holes;

[0008] The negative pressure component is connected to the connecting plate and includes a negative pressure cover connected to the top of the connecting plate and multiple sets of sealing sleeves connected to the negative pressure holes.

[0025] This utility model provides a vacuum suction cup pneumatic clamp. Please refer to [link / reference]. Figure 1-3 It includes a connecting plate 100 and a negative pressure component 200;

[0026] Please continue reading. Figure 1-3 The connecting plate 100, which serves as the connecting substrate, has multiple sets of negative pressure holes 110. The multiple sets of negative pressure holes 110 are arranged in a rectangular equidistant manner along the connecting plate 100, and internal thread grooves 111 are provided in the negative pressure holes 110. The two ends of the connecting plate 100 are symmetrically and integrally connected to the connecting seat 120.

[0027] Please continue reading. Figure 1-3 The negative pressure component 200 is connected to the connecting plate 100, including a negative pressure cover 210 connected to the top of the connecting plate 100, and multiple sets of sealing sleeves 230 connected to the negative pressure holes 110. The outer side of the sealing sleeve 230 is provided with an external thread groove 231 that is screwed into the internal thread groove 111. The negative pressure cover 210 is provided on the outer side of the multiple sets of negative pressure holes 110, and the negative pressure cover 210 is sealed to the top of the connecting plate 100.

[0028] The top of the negative pressure cover 210 is connected to the main pipe 220. The outer side of the main pipe 220 is connected to the connecting pipe 222, which is connected to the external negative pressure end. The bottom of the main pipe 220 is connected to the multi-component pipe 221, which is connected to the negative pressure cover 210. The multi-component pipe 221 is arranged linearly and equidistantly from left to right along the bottom of the outer side of the main pipe 220.

[0029] The external negative pressure end acts on the negative pressure hole 110 through the connecting pipe 222 and the branch pipe 221. The equally spaced branch pipes 221 ensure that the negative pressure is evenly applied to the negative pressure hole 110, so that the negative pressure generated at the negative pressure hole 110 is in a balanced state. At the same time, the negative pressure hole 110 and the sealing sleeve 230 are connected by the internal thread groove 111 and the external thread groove 231. While ensuring the connection is sealed, the screw connection method is convenient for disassembly and assembly, and facilitates subsequent operations such as replacement of the sealing sleeve 230.

[0030] Working principle: When in use, the external negative pressure end acts on the negative pressure hole 110 through the connecting pipe 222 and the branch pipe 221. The equidistant branch pipes 221 ensure that the negative pressure is evenly applied to the negative pressure hole 110, so that the negative pressure generated at the negative pressure hole 110 is in a balanced state, making the workpiece body more firmly fixed, reducing the deformation of thin plate parts, effectively ensuring processing quality, and improving production efficiency. At the same time, the negative pressure hole 110 and the sealing sleeve 230 are connected by the internal thread groove 111 and the external thread groove 231, which ensures the connection is sealed. The screw connection method is convenient for disassembly and assembly, and facilitates subsequent operations such as replacement of the sealing sleeve 230.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
