[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] Please refer to Figures 1-4 The technical solutions provided by the utility model are as follows:

[0022] Embodiment 1

[0023] In this embodiment, a press fitting device with displacement prevention function, including press machine 1, the top of the outer wall of press machine 1 is provided with air cylinder 2, the output end of air cylinder 2 is installed with press rod 3, one end of press rod 3 is connected with linkage rod 4, the outer wall of linkage rod 4 is provided with mounting frame 5 on both sides, the inner wall of mounting frame 5 is movably installed with linkage wheel 6, the outer wall of linkage wheel 6 is installed with fixed frame 7 through coupling on both sides, one end of fixed frame 7 is installed with telescopic rod 8, the outer wall of telescopic rod 8 is installed with spring 9, one end of telescopic rod 8 is installed with fixed plate 10.

[0024] In this embodiment, the outer wall of fixed plate 10 is provided with gasket 11, and the outer wall of press machine 1 is provided with placement table 12.

[0025] In this embodiment, the outer wall of linkage rod 4 is provided with a gear slot on both sides, the gear slot of linkage rod 4 is engaged with the gear slot of linkage wheel 6, and the gear slot of linkage rod 4 drives the linkage wheel 6 movably installed in the inner wall of mounting frame 5 to rotate.

[0026] In this embodiment, one end of fixed frame 7 is connected with the inner wall of linkage wheel 6 through coupling, the other end of fixed frame 7 is fixedly installed with telescopic rod 8, and linkage wheel 6 drives fixed frame 7 to rotate when rotating, and fixed plate 10 installed at one end of telescopic rod 8 is clamped to the part and the mold when fixed frame 7 rotates.

[0027] In this embodiment, the outer wall of fixed plate 10 is connected with gasket 11, the material of gasket 11 is rubber, and gasket 11 provided on the outer wall of fixed plate 10 can increase the friction between fixed plate 10 and the mold to prevent the mold from slipping.

[0028] In the embodiment, the linkage wheels 6 are arranged on both sides of the outer wall of the linkage rod 4, and the linkage wheels 6 are aligned with the tooth grooves of the linkage rod 4. Since the tooth grooves are arranged on both sides of the outer wall of the linkage rod 4, the tooth grooves of the linkage rod 4 drive the linkage wheels 6 movably arranged on the inner wall of the mounting frame 5 to rotate.

[0029] Working principle: in use, first, the user places the parts and the mold on the placement table 12, and then starts the cylinder 2. After the cylinder 2 is started, the pressure assembly rod 3 is driven to press down. One end of the pressure assembly rod 3 is connected with the linkage rod 4, and at this time, the linkage rod 4 is synchronously pressed down to press the parts and the mold. At the same time of moving the linkage rod 4, since the tooth grooves are arranged on both sides of the outer wall of the linkage rod 4, the tooth grooves of the linkage rod 4 drive the linkage wheels 6 movably arranged on the inner wall of the mounting frame 5 to rotate. When the linkage wheels 6 rotate, the fixed frame 7 is driven to rotate, and the fixed plate 10 installed at one end of the telescopic rod 8 is clamped to the parts and the mold. Since the size of the mold is different, the fixed plate 10 generates pressure while clamping, and the pressure drives the telescopic rod 8 and the spring 9 to contract, so that the fixed plate 10 can tightly adhere to the outer wall of the mold of different sizes. In addition, the gasket 11 arranged on the outer wall of the fixed plate 10 can increase the friction between the fixed plate 10 and the mold, prevent the mold from slipping, and keep the linkage rod 4 aligned with the parts during the pressing of the parts, thereby preventing the displacement of the parts and the mold, avoiding damage to the machine and the parts, and improving the stability while maintaining the efficiency of the pressing. Thus, the utility model is completed.
