Description

Technical Field

[0001] This utility model relates to the technical field of vacuum suction cups, specifically a vacuum suction cup for fixing roller assemblies. Background Technology

[0002] A vacuum suction cup is a device that uses the principle of vacuum to adsorb objects. When the vacuum suction cup comes into contact with the surface of an object and removes the internal air, a low-pressure area (close to a vacuum state) is formed inside the suction cup. The external atmospheric pressure is greater than the internal pressure of the suction cup. According to the principle of pressure difference, the external atmospheric pressure will exert a pressure on the suction cup, thereby making the suction cup firmly adsorbed on the surface of the object. In the production and processing of roller assemblies, vacuum suction cups are needed to fix the roller assemblies.

[0003] Most existing vacuum suction cups are connected to the vacuum pump pipes by threads. However, threaded connections require good alignment. If the thread axis is not aligned, additional bending stress will be generated during tightening, affecting the stability of the suction cup connection and the sealing effect, and reducing the subsequent effect of fixing the roller assembly. Therefore, it is necessary to propose a vacuum suction cup for fixing the roller assembly. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum suction cup for fixing roller assemblies, so as to solve the problems mentioned in the background art.

[0006] The installation mechanism includes an insert plate, a sealing ring, a pipe, a fixing plate, a connecting plate, a rotating rod, a threaded rod, a locking plate, a rotating handle, a locking rod, an engaging plate, an insert block, and a slider. The insert plate is fixedly connected to the lower part of the suction cup body. The sealing ring is movably connected to the inner wall of the suction cup body. The pipe is fixedly connected to the inner wall of the sealing ring. The fixing plate is fixedly connected to the outer wall of the pipe.

One end of the rotating rod is fixedly connected to a threaded rod, and the locking plate is fixedly connected to one end of the rotating rod. The rotating handle is fixedly connected to one side of the locking plate, and the locking rod is movably connected to the inside of the locking plate.

[0007] Preferably, the outer wall of the positive and negative threaded rod is movably connected to a meshing plate, a plug is fixedly connected to one side of the meshing plate, and a slider is fixedly connected to the lower part of the meshing plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This vacuum suction cup for fixing roller assemblies, in conjunction with an installation mechanism, involves inserting the suction cup body through a hole in the support platform, connecting the insert plate to the fixing plate, and inserting a pipe into the suction cup body. Rotating the handle causes the rotating rod, locking plate, and positive and negative threaded rods to rotate. The engagement of the positive and negative threaded rods with the meshing plate, along with the angular limitation of the slider's movement within the support platform, moves the insert block and inserts it into the fixing plate, penetrating the insert plate. The locking rod is then sequentially connected to the through hole in the locking plate and the hole in the connecting plate, locking the positive and negative threaded rods and simultaneously locking the position of the insert block. This connects the suction cup body to the pipe, effectively improving the stability and sealing effect of the connection between the suction cup body and the pipe, enhancing the subsequent fixing effect of the roller assembly, and indirectly improving the processing effect of the roller assembly. This, in turn, enhances the practicality of the vacuum suction cup.

[0014] 2. This vacuum suction cup for fixing roller assemblies, through the setting of the support mechanism, allows the first ring body to be lower than the horizontal line of the suction cup body during the use of the vacuum suction cup, thereby enabling the steel wire rope to support the roller assembly, improving the stability of fixing the roller assembly, and improving the processing effect of the roller assembly, thus improving the applicability of the vacuum suction cup to a certain extent.

A rotating handle 309 is fixedly connected to one side of the locking plate 308. A locking rod 310 is movably connected inside the locking plate 308. The locking rod 310 passes through the interior of the locking plate 308 and extends to... Inside the connecting plate 305, the locking rod 310 is movably connected to the locking plate 308 and the connecting plate 305, improving the stability of locking the positive and negative threaded rod 307, thereby improving the stability of the engagement of the insert block 312 with the fixing plate 304 and the insert plate 301. The outer wall of the positive and negative threaded rod 307 is movably connected to the meshing plate 311, and the insert block 312 is fixedly connected to one side of the meshing plate 311. The insert block 312 penetrates the interior of the fixing plate 304 and extends into the interior of the insert plate 301.

[0023] In this embodiment, the support mechanism 4 includes a first ring body 401, a steel wire rope 402, and a second ring body 403. The first ring body 401 is fixedly connected to the top of the support platform 1, the steel wire rope 402 is fixedly connected inside the first ring body 401, and the second ring body 403 is fixedly connected to one end of the steel wire rope 402.

[0024] Working principle: When using the vacuum suction cup for fixing the roller assembly, firstly, insert the insertion plate 301 below the suction cup body 2 into the slot inside the fixing plate 304 and insert it through the hole inside the support platform 1, so that the insertion plate 301 penetrates through the inside of the fixing plate 304 and extends to the bottom of the fixing plate 304, thereby driving the pipe 303 to be inserted into the suction cup body 2. The connection between the suction cup body 2 and the pipe 303 is sealed by the sealing ring 302 on the outer wall of the pipe 303 and the fixing plate 304. Then, rotate the handle 309 to drive the rotation of the rotating rod 306, the locking plate 308 and the positive and negative threaded rod 307. Then, through the mutual engagement of the positive and negative threaded rod 307 with the threaded hole inside the engagement plate 311, and the movement of the slider 313 above the engagement plate 311 inside the support platform 1 to limit the angle of the engagement plate 311, the engagement plate 311 is driven to move against the outer wall of the positive and negative threaded rod 307. The suction cup is moved horizontally, causing the insertion block 312 to move and insert into the fixing plate 304 through the insertion plate 301. Then, the locking rod 310 is connected to the through hole inside the locking plate 308 and the hole inside the connecting plate 305 in sequence to lock the state of the positive and negative threaded rod 307 and lock the position of the insertion block 312. This completes the installation of the suction cup body 2 and the pipe 303. Then, the roller assembly is placed on the suction cup body 2, and the part of the suction cup body 2 extending from the support platform 1 contacts the roller assembly. Then, the air inside the suction cup body 2 is extracted through the vacuum pump and the pipe 303 to fix the roller assembly. The first ring 401 is lower than the horizontal line of the suction cup body 2, so that the steel wire rope 402 supports the roller assembly, improving the stability of fixing the roller assembly. In this way, the process of using the vacuum suction cup to fix the roller assembly is completed.
