[0002] In the fixture design industry, many supporting mechanisms need to be operated in a very small space with the least number of operating steps to achieve simultaneous operation of multiple actions, ensure simultaneous contact of the pressing surface, and prevent the contact surface from tilting. When designing the existing pressing structure, it is often encountered that the pressing blocks are distributed in different areas, which will cause multiple actions during operation, and will also cause asynchronous situations, the surface of the pressed product is inconsistent in the hands, and the product is crushed. In today's era of advanced technology, it is necessary to avoid the complicated operation procedures of operators and the limitations of the operating space, reduce unnecessary damage and crushing of products, or separate the pressure cover and the carrier, and remove the pressure cover to prevent the product from being pressed again. This method requires manual or multiple groups of manipulators to perform multiple operations to complete loading and unloading, and cannot achieve the linkage of product loading and unloading and the opening and closing of the pressing structure. The efficiency is low and does not meet the needs of enterprises for efficient production. If a simple structure, convenient operation, symmetrical structure can be designed to achieve simultaneous opening and closing, avoid tilting of products at different times, and convert horizontal movement into oblique opening and closing, and a more applicable linkage symmetrical pressing structure, the above problems can be solved.

DETAILED DESCRIPTION

[0014] like Figures 1 to 7As shown, in this embodiment, the present invention includes a base 1, a bevel-shaped push plate 2 and a pressure block module 3, the pressure block module 3 includes a left pressure block 31 and a right pressure block 32, both ends of the base 1 are provided with a plurality of mounting inclined holes 4 extending toward the bottom center, the left pressure block 31 and the right pressure block 32 are respectively slidably matched with the plurality of mounting inclined holes 4 at both ends of the base 1 through a plurality of linear bearings 5, the bevel-shaped push plate 2 is arranged at the lower end of the base 1, both side ends of the bevel-shaped push plate 2 are provided with bevel-shaped grooves 6 inclined in the same direction, rolling bearings 7 are arranged on both sides of the lower ends of the left pressure block 31 and the right pressure block 32, the bevel-shaped push plate 2 drives the left pressure block 31 and the right pressure block 32 to respectively cooperate with the plurality of bevel-shaped grooves 6 so that the left pressure block 31 and the right pressure block 32 are pressed together or away from the carrier 8 at the upper end of the base 1. It can be seen that the rolling bearing 7 rolls on the bevel-shaped groove 6 to realize the lifting and lowering of the pressure block module 3 in the height direction, and the mounting inclined hole 4 and the linear bearing 5 realize the oblique opening and pressing of the left pressure block 31 and the right pressure block 32, so that the base 1 can be loaded and unloaded in the vertical direction without being interfered by the pressure block, and the left pressure block 31 and the right pressure block 32 move synchronously, which can ensure that the pressure at both ends of the carrier 8 is evenly applied.

[0015] like Figure 4 and Figure 5 As shown, in this embodiment, an inclined spring 9 is disposed between the left pressing block 31 and the right pressing block 32 and both ends of the base 1, and the inclined spring 9 has the same inclination angle as the inclined mounting hole 4. It can be seen that the same inclination angle of the inclined spring 9 and the inclined mounting hole 4 can ensure that the buffering and resetting force of the sliding pressing are more uniform, thereby reducing friction.

[0016] like Figure 1 and Figure 2 As shown, in this embodiment, a push block 10 is provided at one end of the bevel-shaped push plate 2, and the push block 10 drives the bevel-shaped groove 6 on the bevel-shaped push plate 2 to cooperate with the pressing block module 3. It can be seen that the push block 10 makes it more convenient for manual or mechanical hands to operate the bevel-shaped push plate 2, and the sliding process of the bevel-shaped push plate 2 is more stable.

[0017] like Figures 3 to 5 As shown, in this embodiment, a plurality of floating springs 11 are provided at one end of the bevel-shaped push plate 2 away from the push block 10, and the bevel-shaped push plate 2 cooperates with the corresponding end of the base 1 through the plurality of floating springs 11. It can be seen that the plurality of floating springs 11 provide buffering for opening and tension for the bevel-shaped push plate 2 in the pressed state.

[0018] like Figures 1 to 5As shown, in this embodiment, a lower cover plate 12 is provided at the lower end of the base 1, and the yoke-shaped push plate 2 is provided between the base 1 and the lower cover plate 12 and slidably cooperates with the base 1. It can be seen that the lower cover plate 12 enables the yoke-shaped push plate 2 to slide stably at the lower end of the base 1 without deflection or falling off.

[0019] like Figures 1 to 3 As shown, in this embodiment, the upper end of the base 1 is provided with a carrier profiling groove 13, and the carrier 8 is limitedly matched with the carrier profiling groove 13. It can be seen that the carrier profiling groove 13 realizes the limitation of the carrier 8 to prevent deviation during the pressing process.

[0020] like Figure 6 As shown, in this embodiment, the left pressing block 31 and the right pressing block 32 are both provided with pressing extension blocks 14 at the pressing ends, and the pressing extension blocks 14 are matched with the two ends of the upper end surface of the carrier 8. It can be seen that the pressing extension blocks 14 are in contact with the edge of the carrier 8, so that the carrier 8 is fixed on the carrier profiling groove 13.

[0021] like Figure 6 As shown, in this embodiment, a flexible buffer layer is provided at the bottom of the pressing extension block 14. It can be seen that the flexible buffer layer can prevent the surface of the carrier 8 from being scratched.

[0022] The working principle of the present invention is as follows: before the pressing and positioning, a manual or mechanical arm pushes the oar-shaped push plate 2 inward through the push block 10, and the rolling bearings 7 on the left pressure block 31 and the right pressure block 32 roll to the high position of the oar-shaped groove 6 under the action of the oar-shaped groove 6, and the left pressure block 31 and the right pressure block 32 move obliquely outward under the guidance of the linear bearing 5 and the mounting inclined hole 4, and the carrier 8 is placed in the carrier profiling groove 13, and the push block 10 is released. The oar-shaped push plate 2 is reset under the action of the floating springs 11, and at the same time, the inclined tension springs 9 pull the left pressure block 31 and the right pressure block 32 to reset and press down, and the pressing extension blocks 14 on the left pressure block 31 and the right pressure block 32 contact and press at both ends of the carrier 8 to achieve the linkage and symmetrical downward pressure on the carrier 8.

[0023] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
