[0024] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.
[0025] It has to be understood that the terms "comprising", "having", "including" and "containing" and any variations thereof in the present application and in the accompanying claims are intended to cover both the case where the step or unit is present and the case where it is not present, i.e. the case where the step or unit is not included.
[0026] The application will be further described below with reference to the drawings. Figures 1-3 The application will be further described below with reference to the drawings.
[0027] Reference is made to Figures 1-3 A tool buffering device, comprising: a fixed plate 100, a floating bottom plate 200, an elastic member 300, a limiting mechanism and a fixing mechanism, the floating bottom plate 200 is suspended directly above the fixed plate 100, the elastic member 300 is arranged between the fixed plate 100 and the floating bottom plate 200; the limiting mechanism is used for limiting the movement of the floating bottom plate 200, so that the floating bottom plate 200 can only make lifting movement; the fixing mechanism is used for fixing the tool placed on the floating bottom plate 200, so that when in use, the device is installed on the equipment, and the required tool is installed on the floating bottom plate 200, the fixing mechanism is used for fixing the tool, in the initial state, the floating bottom plate 200 keeps the state of floating upward under the action of the elastic member 300 (as shown in Figure 2 ), that is, there is a certain distance of downward floating allowance, when the tool is subjected to pressure, the floating bottom plate 200 is synchronously subjected to pressure, the floating bottom plate 200 moves downward, and the elastic member 300 is compressed (as shown in Figure 3 ), thereby providing buffering for the tool, so as to reduce the probability of the case that the tool and the product on the tool are damaged due to hard pressure.
[0028] As Figures 1-3As shown, in order to limit the movement of the floating bottom plate 200, the limiting mechanism includes a plurality of guide assemblies, which are uniformly distributed in the horizontal direction of the floating bottom plate 200. The guide assembly specifically includes a guide shaft 400 and a linear bearing 500. The linear bearing 500 is provided on the fixed plate 100, and the guide shaft 400 is provided at the linear bearing 500. The top end of the guide shaft 400 is connected to the floating bottom plate 200. The movement of the guide shaft 400 is limited by the linear bearing 500 and the guide shaft 400. Since the top end of the guide shaft 400 of the plurality of guide assemblies is connected to the floating bottom plate 200, the movement of the floating bottom plate 200 is limited, so that the floating bottom plate 200 can only move up and down, ensuring the accuracy of the workpiece machining. The limiting mechanism also includes a limiting plate 600 arranged below the fixed plate 100. The bottom of the plurality of guide shafts 400 is connected to the limiting plate 600. The position of the floating bottom plate 200 is limited by the limiting plate 600.
[0029] As shown in Figures 1-3 The fixing mechanism is provided with two, which are arranged on both sides of the floating bottom plate 200. The fixing mechanism includes a bolt 700 and a lifting ring nut 800. The bottom end of the bolt 700 is connected to the floating bottom plate 200, and the lifting ring nut 800 is screwed on the bolt 700. In this way, when installing the tooling, the tooling is arranged between the two bolts 700. By screwing the lifting ring nut 800, the lifting ring nut 800 moves from top to bottom until the lifting ring nut 800 is pressed against the top surface of the tooling on both sides, completing the fixation of the tooling, and facilitating the disassembly and assembly of the tooling. The bolt 700 is rotatably connected to the floating bottom plate 200. The rotation direction of the two bolts 700 is towards each other or away from each other. When installing the tooling, the two bolts 700 are rotated to the two sides, the tooling is arranged on the floating bottom plate 200, and then the two bolts 700 are rotated to the side close to each other, and the lifting ring nut 800 is screwed to fix it. In order to realize the rotation of the bolt 700 relative to the floating bottom plate 200, the two sides of the floating bottom plate 200 are provided with a rotating shaft 210. The bolt 700 is a fish-eye bolt, and the annular end of the bolt 700 is sleeved on the rotating shaft 210. In this way, the bolt 700 can rotate around the rotating shaft 210.
[0030] Further optimization is as shown in Figures 1-3 In order to facilitate the positioning of the tooling during installation, the top surface of the floating bottom plate 200 is provided with a plurality of positioning pins 220. The installation position of the tooling relative to the floating bottom plate 200 is determined by the plurality of positioning pins 220.
[0031] Further optimization is as shown in Figures 1-3As shown, the floating of the floating bottom plate 200 mainly depends on the elastic force of the elastic member 300, in order to achieve this purpose, the elastic member 300 can be composed of a plurality of springs, a plurality of rubber columns or a plurality of elastic sheets, and can also be composed of a combination of springs, rubber columns and elastic sheets.
[0032] Further optimization is that, as shown, in order to facilitate the installation of the device on the equipment, a plurality of mounting holes 110 are arranged on both sides of the fixing plate 100, and the fixing plate 100 can be fixed on the equipment through the plurality of mounting holes 110. Figure 1
[0033] In summary, in use, the device is installed on the equipment, and the required tooling is installed on the floating bottom plate 200, and the fixing tooling is fixed by the fixing mechanism, in the initial state, the floating bottom plate 200 is kept in the state of floating upward under the action of the elastic member 300, that is, it has a certain distance of downward floating margin, when the tooling is subjected to pressure, the floating bottom plate 200 is synchronously subjected to pressure, the floating bottom plate 200 moves downward, compresses the elastic member 300, and further provides buffer for the tooling, thereby reducing the probability of damage to the tooling and the product on the tooling caused by hard pressure.
