[0003] At present, the flange plate is usually inconvenient to position during installation, and the bolt cannot be accurately inserted into the mounting hole on the flange plate during bolt fixing, so that the installation efficiency is reduced, and meanwhile, after installation, there is a certain gap between the flange plate and the mounting component, which will cause the flange plate connection to be loose in the long-term working state of the robot, and further cause the parts to fall off. SUMMARY

[0004] The utility model discloses a flange plate convenient to position and good in sealing property is provided aiming at the above problems in the prior art.

[0005] The utility model discloses a flange plate, including flange plate main part, the left side of flange plate main part is set up with installation slot, positioning pin hole and mounting hole respectively, the right side of flange plate main part is integrative and has flange cylinder, the right side of flange cylinder outer surface is set up with thread cut -groove, the outer ring of flange plate main part right side is set up with washer groove, the inside of washer groove is provided with sealing washer, the inner chamber of flange plate main part is inlayed and is installed with spring, the inner side of spring is fixedly connected with connecting rubber ring, the inner ring of connecting rubber ring is fixedly connected with sealing rubber ring.

[0006] By setting sealing rubber ring in the inside of flange plate main part, the stable connection between the mounting piece and flange plate main part is realized, the stability during connection is ensured, and the sealing property during installation is improved, so that the lubricating oil is prevented from seeping into and causing the installation to be loose and fall off.

[0007] In the above flange plate, the inner ring of the left side of the flange plate main part is provided with a chamfer groove one, and the outer ring of the right side of the flange cylinder is provided with a chamfer groove two. The setting of the chamfer groove one enables the mounting piece to be more conveniently inserted into the inside of the flange plate main part, achieving the effect of convenient installation, and the setting of the chamfer groove two enables the components outside the flange cylinder to be more quickly sleeved on the surface of the flange cylinder.

[0008] In the above-mentioned flange plate, the number of the mounting slot, the positioning pin hole and the mounting hole is three, and they are evenly staggered, and the mounting slot is through to the outside of the flange plate body. The setting of the mounting slot can facilitate the insertion and installation of the robot parts, effectively improve the installation adaptability of the flange body, the mounting hole can facilitate the screw to pass in, so as to fix the flange plate body on the surface of the mounting part, and the positioning pin hole can facilitate the insertion of the positioning pin, and facilitate the positioning during installation.

[0009] In the above-mentioned flange plate, the edge of the left side of the sealing rubber ring is chamfered, and the sealing rubber ring is made of natural rubber material. The chamfering treatment can make the sealing rubber ring open outward when the mounting part contacts with the sealing rubber ring, so as to facilitate the insertion of the mounting part into the sealing rubber ring.

[0010] In the above-mentioned flange plate, the inner cavity of the flange plate body is provided with an installation groove for installing the spring, the connecting rubber ring and the sealing rubber ring, and the sealing rubber ring is in sliding contact with the inner wall of the installation groove. The setting of the spring can apply a spring force to the sealing rubber ring, so that it is always located on the surface of the mounting part and does not shake, and the connecting rubber ring can better support the sealing rubber ring and improve the stability of the sealing rubber ring.

[0011] Compared with the prior art, the flange plate has the advantages that: the three positioning pin holes can effectively position the flange plate body during installation, can make the bolt stably inserted into the mounting hole on the flange plate body during installation, achieve the effect of rapid installation, and after the positioning pin is inserted into the positioning pin hole, the stability of the flange plate body during installation is improved, and the flange plate body is prevented from shaking. The sealing rubber ring is installed in the flange plate body, and the sealing rubber ring is in close contact with the surface of the mounting part, which can ensure the sealing between the flange plate body and the mounting part, and further improve the stability of the installation, so that the flange plate body is prevented from falling off.

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figures 1-5 As shown, this flange includes a flange body 1. The left side of the flange body 1 is provided with a mounting slot 3, a positioning pin hole 6 and a mounting hole 7. The right side of the flange body 1 is integrally formed with a flange cylinder 4. The right side of the outer surface of the flange cylinder 4 is provided with a threaded groove 5. The outer ring of the right side of the flange body 1 is provided with a gasket groove 8. A sealing gasket 9 is provided inside the gasket groove 8. A spring 10 is embedded in the inner cavity of the flange body 1. A connecting rubber ring 11 is fixedly connected to the inner side of the spring 10. A sealing rubber ring 12 is fixedly connected to the inner ring of the connecting rubber ring 11.

[0020] To elaborate further, the inner ring on the left side of the flange body 1 has a chamfered groove 2, and the outer ring on the right side of the flange cylinder 4 has a chamfered groove 2. There are three mounting slots 3, three locating pin holes 6, and three mounting holes 7, which are evenly and alternately distributed. One side of the mounting slot 3 extends to the outside of the flange body 1.

[0021] The left edge of the sealing ring 12 is chamfered, and the sealing ring 12 is made of natural rubber. The inner cavity of the flange body 1 is provided with a mounting groove for installing the spring 10, the connecting ring 11 and the sealing ring 12. The sealing ring 12 is in sliding contact with the inner wall of the mounting groove.

[0022] In practical applications, the flange body 1 is placed in the installation position. First, the locating pin hole 6 is aligned with the installation position, and a locating pin is inserted into the locating pin hole 6 to position the flange body 1. Then, a screw is inserted into the mounting hole 7 to fix it in the installation position. During this process, the surface of the mounting part penetrates into the interior of the flange body 1, causing the surface of the mounting part to press against the inclined surface on the left side of the sealing ring 12, thereby pushing the sealing ring 12 outward until the mounting part completely passes through the sealing ring 12. At this point, the sealing ring 12 is pushed open and fills the inner wall of the mounting groove, thereby achieving a sealing effect and ensuring a stable connection between the mounting corner and the flange body 1.

[0023] What is not described in detail in the specification belongs to the prior art known to those skilled in the art. The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
