[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1-5As shown, a signal transmission structure of a press machine includes a press machine body 10, to which a pressure cover 1 is fixedly connected, a connecting plate 2 is fixedly connected to the lower end of the pressure cover 1, two half-couplings 3 are fixedly connected to the lower end of the connecting plate 2, and a gasket 4 is installed between the two half-couplings 3. The press machine body 10 is also equipped with a transmission shaft 5 and a cam controller 9, the transmission shaft 5 is rotatably connected to the press machine body 10, the upper end of the transmission shaft 5 is fixedly connected to the half-coupling 3 located at the lower end, and the transmission shaft 5 and the cam controller 9 are connected through a transmission component. At this time, when the pressure cover 1 rotates, the half-coupling 3 and the gasket 4 are driven to rotate through the connecting plate 2, so that the gasket 4 transmits the transmission shaft 5. When the transmission shaft 5 rotates, the cam controller 9 is driven to work through the transmission component, and during the transmission process, the stress on the transmission shaft 5 during operation is reduced by the half-coupling 3 and the gasket 4, thereby reducing the probability of damage to the transmission shaft 5.

[0023] The gasket 4 is made of rubber, which has good buffering performance and can weaken the force it receives through its own material.

[0024] Among them, Figure 3-5 As shown, the half coupling 3 includes a coupling body 11, and three protrusions 12 in a ring array are fixedly connected to the edge position of the coupling body 11 close to the gasket 4. The gasket 4 includes a pad body 13, and six grooves 14 in a ring array are opened on the circumference of the pad body 13. The protrusions 12 are snapped into the inside of the grooves 14. At this time, by installing the protrusions 12 in the inside of the grooves 14, the rotational kinetic energy can be effectively transmitted between the half coupling 3 and the gasket 4.

[0025] Among them, Figure 2 As shown, the transmission assembly includes two sprocket wheels 7, one of which is installed at the upper end of the cam controller 9, and the other is installed at the lower end of the transmission shaft 5. Chains 8 are installed on the outer sides of the two sprocket wheels 7. When the transmission shaft 5 rotates, the sprocket wheel 7 at its lower end will be driven to rotate. When the sprocket wheel 7 rotates, the other sprocket wheel 7 will be driven to rotate through the chain 8, thereby inputting kinetic energy into the cam controller 9. Its structure is relatively simple and the transmission process is relatively stable.

[0026] Among them, a screw hole is opened at the lower end of the pressure cover 1, and a screw is installed on the connecting plate 2. The screw thread is connected to the inside of the screw hole, so that the connection is more stable and the installation is simpler.

[0027] At the same time, in order to reduce the wear of the transmission shaft 5 during rotation, a flange 6 is fixedly connected to the press body 10, and a ball bearing is installed inside the flange 6. The transmission shaft 5 is rotatably connected to the inside of the flange 6 through the ball bearing. The setting of the ball bearing can effectively reduce the wear of the transmission shaft 5 during rotation.

[0028] The working principle of the utility model is as follows: when the gland 1 rotates, it drives the half coupling 3 and the gasket 4 to rotate through the connecting plate 2, so that the gasket 4 transmits the transmission shaft 5, and when the transmission shaft 5 rotates, it drives the sprocket 7 at the lower end thereof to rotate, and when the sprocket 7 rotates, it drives another sprocket 7 to rotate through the chain 8, thereby inputting kinetic energy into the cam controller 9, and driving the cam controller 9 to work;

[0029] In summary, the structure adopts the connection form of connecting plate 2, half coupling 3, and gasket 4, which has a simple structure, is convenient for maintenance and disassembly, has low maintenance cost, greatly reduces the factory's own processing requirements, and also improves the installation accuracy, ensures the accuracy of transmission, and can eliminate the damage to the transmission shaft 5 caused by stress concentration, truly meeting the requirements of simple processing, easy installation, high installation accuracy and low failure rate of the signal transmission mechanism.

[0030] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
