[0003] When deburring industrial products such as die-cast parts, injection molded parts, and machined parts, a grinding device is often required to provide axial force. However, existing grinding devices are too large, lack precision when grinding small workpieces, and are also costly, which is not conducive to mass production. Utility Model Content

[0014] In a preferred embodiment, a limiting block is also included, and only one piston rod is provided along the sliding guide direction of the slide rail. The limiting block and the piston rod are respectively provided on both sides of the slider along the sliding guide direction of the slide rail.

[0015] In a preferred embodiment, the sliding seat is provided with a plurality of vent holes to enhance the sensitivity of the piston rod. The vent holes are connected to the piston hole and are located on the extended side of the piston rod.

[0033] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0035] Example 1

[0036] This utility model embodiment provides an axial floating device for deburring robots, such as... Figure 1 and Figure 2 As shown, the device includes a fixed plate 2 and a sliding seat 1 that are slidably connected to each other. The fixed plate 2 is used to connect with an industrial robot, and the sliding seat 1 is used to connect with a grinding mechanism. A slider 7 is fixedly mounted on the fixed plate 2, and a slide rail 8 is fixedly mounted on the sliding seat 1. The slider 7 is slidably connected to the slide rail 8. A piston hole 11 is provided inside the sliding seat 1, and a piston rod is slidably connected to it inside the piston hole 11. An air inlet plug 13 is provided on the sliding seat 1. One end of the air inlet plug 13 is connected to the inside of the sliding seat 1, and the other end is connected to an external air pump to drive the piston rod to move. When the axial floating device of this utility model is used to connect the grinding mechanism to perform deburring operations on the workpiece, the grinding mechanism applies a force to the workpiece. Correspondingly, the workpiece applies a reaction force to the grinding mechanism. The grinding mechanism transmits this force to the sliding seat 1. The sliding seat 1 is also subjected to the pushing force of the piston rod along the guiding direction of the slide rail 8. When the relative magnitude of the above two forces changes, the sliding seat 1 can slide relative to the fixed plate 2 accordingly, producing an axial floating effect. It can not only adapt to the workpiece plane in real time, but also has a compact structure, low cost, and is easy to mass-produce.

[0037] Furthermore, such as Figure 3 and Figure 4 As shown, in this embodiment, the piston rods are arranged in pairs, along the sliding guide direction of the slide rail 8, and are respectively located on both sides of the slider 7. For easy distinction, the two piston rods are defined as the first piston rod 5 and the second piston rod 9. Figure 4 The piston rods are positioned such that the first piston rod 5 and the second piston rod 9 extend out of the piston hole 11, clamping the fixing plate 2, thereby placing the sliding seat 1 in the center position of the fixing plate 2. To reduce weight and ensure good processing performance, the fixing plate 2 in this embodiment is made of aluminum alloy. However, the aluminum alloy fixing plate 2 is prone to deformation after being repeatedly pushed by the piston rods on both sides, leading to reduced strength and even preventing the sliding process from being completed normally. Figure 2 or Figure 4 As shown, a steel plate 6 is provided between the piston rod and the fixed plate 2 to prevent the fixed plate 2 from being repeatedly pushed and worn. One side of the steel plate 6 is fixedly connected to the slider 7, and the other side is used to abut against the piston rod.

[0038] like Figure 3As shown, the sliding seat 1 has several vent holes 12, which are used to enhance the sensitivity of the piston rod and reduce exhaust noise. The vent holes 12 are connected to the piston hole 11 and are located on the extended side of the piston rod. More preferably, the inner wall of the piston hole 11 and the surface of the piston rod are both provided with a Teflon coating. Based on the properties of Teflon itself, the Teflon coating can effectively reduce the coefficient of friction and provide wear resistance, ensuring the sensitivity and axial floating effect of the piston rod.

[0039] like Figure 2 As shown, the axial floating device in this embodiment also includes a sealing plate 3, which covers the sliding seat 1, with one end abutting against the sliding seat 1 and the other end abutting against the fixed plate 2. The sealing plate 3 can cover the internal structure of the device exposed due to sliding, providing dustproof and waterproof effects and improving the aesthetic effect. It also includes a cover plate 4, which is detachably connected to the sliding seat 1 and used to seal the piston hole 11 to ensure stable internal air pressure.

[0040] More preferably, the axial floating device in this embodiment also includes a precision pressure regulating valve, which is connected to the air inlet plug 13 and is used to adjust the air pressure. It can adjust the air pressure according to the required floating effect in actual process, thereby changing the piston rod thrust.

[0041] When the axial floating device of this embodiment is used to connect the grinding mechanism to perform deburring on the workpiece, the grinding mechanism applies a force to the workpiece, and correspondingly, the workpiece applies a reaction force to the grinding mechanism. The grinding mechanism transmits this force to the sliding seat 1. The sliding seat 1 is also subjected to the pushing force of the piston rods on both sides along the guide direction of the slide rail 8. When the relative magnitude of the reaction force of the workpiece and the pushing force of the piston rods on both sides changes, the sliding seat 1 can slide relative to the fixed plate 2 accordingly, producing an axial floating effect. It can not only adapt to the workpiece plane in real time, but also has a compact structure, low cost, and is easy to mass-produce.

[0042] Example 2

[0043] This embodiment is an alternative implementation method that differs from Embodiment 1, and the repeated parts will not be described in detail here.

[0044] Please refer to the following: Figures 5 to 7 This embodiment can be seen as an adjustment based on the axial floating device in Embodiment 1. Specifically, the piston hole 11 on the second piston rod 9 and the sliding seat 1 used to accommodate the second piston rod 9 in Embodiment 1 is removed, and an additional limiting block 10 is added. The limiting block 10 and the first piston rod 5 are respectively disposed on both sides of the slider 7 along the sliding guide direction of the slide rail 8. The axial floating principle of this embodiment is the same as the axial floating principle in Embodiment 1.

[0045] In summary, this utility model relates to an axial floating device for deburring robots. It comprises a fixed plate 2 and a sliding seat 1 that are slidably connected to each other. The fixed plate 2 is used to connect with an industrial robot, and the sliding seat 1 is used to connect with a grinding mechanism. A slider 7 is fixedly mounted on the fixed plate 2, and a slide rail 8 is fixedly mounted on the sliding seat 1. The slider 7 is slidably connected to the slide rail 8. A piston hole 11 is provided inside the sliding seat 1, and a first piston rod 5 is slidably connected thereto within the piston hole 11. An air inlet plug 13 is provided on the sliding seat 1, with one end connected to the interior of the sliding seat 1 and the other end connected to an external air pump. When the grinding mechanism is connected to the axial floating device of this utility model to perform deburring operation on the workpiece, the grinding mechanism applies a force to the workpiece, and the workpiece applies a reaction force to the grinding mechanism. The grinding mechanism transmits this force to the sliding seat 1. The sliding seat 1 is also subjected to the pushing force of the first piston rod 5 along the guide direction of the slide rail 8. When the relative magnitude of the two forces changes, the sliding seat 1 can slide relative to the fixed plate 2 to produce an axial floating effect. It can not only adapt to the workpiece plane in real time, but also has a compact structure, low cost, and is easy to mass-produce.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
