Technical Field

[0001] This utility model relates to the technical field of deburring equipment for machining, specifically an automatic grinding and deburring fixture. Background Technology

[0002] During machining, burrs are often generated on the surface of the workpiece. These burrs not only affect the appearance quality of the workpiece, but may also have an adverse effect on subsequent assembly and use.

[0003] Chinese patent CN219188875U provides an automatic deburring and polishing fixture, including a polishing tool fixing device, workpiece contour scanning devices on both sides of the polishing tool fixing device, and a dust collection device below the polishing tool fixing device. The polishing tool fixing device includes a polishing column and a J-shaped polishing frame horizontally mounted on the polishing column. Pneumatic files are respectively mounted at both ends of the polishing frame, with the blades of both pneumatic files facing inwards towards the polishing frame. This automatic deburring and polishing fixture, by using two opposing pneumatic files, can polish burrs from both above and below the workpiece, avoiding the need for industrial robots to reverse and reposition the workpiece, thus greatly improving the efficiency of burr removal from drilled holes. However, the size of the polishing frame in the above technical solution is not adjustable, making the fixed spacing between the two pneumatic files unsuitable for workpieces of different sizes.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0024] like Figure 1-3 As shown, this embodiment provides an automatic grinding and deburring fixture, including a collection box 1, a support frame 2 vertically arranged in the middle of the collection box 1, a grinding mechanism 3 arranged on the top of the support frame 2, and data acquisition devices 4 arranged on both sides of the grinding mechanism 3.

[0025] In this embodiment, the grinding mechanism 3 includes a horizontally arranged housing 31. A support 32 is located at one end of the housing 31, and a pneumatic file 33 with its grinding head facing upwards is located at the outward-facing end of the support 32. A telescopic mechanism 34 is located inside the housing 31. The extended end of the telescopic mechanism 34 extends from the other end of the housing 31 and is equipped with an upwardly curved J-shaped support 35. The end of the support 35 is equipped with the pneumatic file 33 with its grinding head facing downwards. This design, by using two opposing pneumatic files, satisfies the need to grind burrs at the drilled holes from both ends of the workpiece, avoiding the need for the industrial robot to reverse and reposition the workpiece, greatly improving the efficiency of burr removal at the drilled holes. Furthermore, the telescopic mechanism 34 can accommodate grinding needs of workpieces of different sizes, demonstrating good adaptability. In this embodiment, the telescopic mechanism 34 is an electrically controlled telescopic rod.

[0026] In this embodiment, a sealing ring 37 is provided at one end of the housing 31 facing the bracket 35. The protruding end of the telescopic mechanism 34 passes through the sealing ring 37 and is in close contact with the inner wall of the sealing ring 37 to prevent dust and other impurities from entering the interior of the housing 31 and to ensure the normal operation of the telescopic mechanism 34.

[0027] In this embodiment, a ring 39 is provided at the outward end of the housing 31 via a mounting bracket 38. Brush bristles 391 are provided on the inner side of the ring 39. The brush bristles 391 contact the extended end of the telescopic mechanism 34 to further clean impurities on the surface of the extended end of the telescopic mechanism 34.

[0028] In this embodiment, a plurality of air nozzles 392 are evenly distributed on the outward side of the ring 39. The air nozzles 392 are connected to the air supply device through the air pipe 393. The air nozzles 392 spray air to clean impurities on the surface of the extended end of the telescopic mechanism, ensuring smooth movement of the telescopic mechanism 34.

[0029] In this embodiment, baffles 36 are provided on the outer sides of the outward-facing ends of bracket 1 32 and bracket 2 35 to prevent debris from flying during the grinding process and to protect the safety of the operators.

[0030] In this embodiment, the data acquisition device 4 includes a column 41 arranged in a ring around the grinding mechanism 3. The top of the column 41 is provided with an inward-facing acquisition camera 42, which is used to collect information such as the shape and size of the workpiece to provide data support for the grinding operation.

[0031] In this embodiment, a rotating mechanism 7 is provided below the column 41. The rotating mechanism 7 includes an annular base 71, with several supporting legs 72 evenly distributed on the bottom of the base 71. An annular groove 73 is provided on the upper surface of the base 71, and an annular turntable 74 is rotatably mounted within the annular groove 73. Several universal rollers 75 are evenly distributed on the bottom of the annular turntable 74, and the upper surface of the annular turntable 74 is fixedly connected to the bottom of the column 41. The operator can manually rotate the annular turntable 74 to adjust the position and angle of the acquisition camera 42, thereby acquiring workpiece information more comprehensively and accurately. In this embodiment, the column 41 is an electrically controlled telescopic rod.

[0032] In this embodiment, a funnel-shaped cover 5 is provided around the periphery of the grinding mechanism 3, and the inner side of the cover 5 is connected to the support frame 2 via a connecting rod 51. The funnel-shaped cover 5 can collect the dust generated during the grinding process into the collection box 1, thereby improving the working environment.

[0033] The working principle of the above technical solution is as follows:

[0034] First, the operator manually rotates the annular turntable 74, causing the column 41 and the top-mounted acquisition camera 42 to adjust their position and angle. The acquisition camera 42 collects data such as the shape and size of the workpiece and transmits the data to the industrial robot that grips the workpiece. This provides the industrial robot with precise contour data and workpiece dimensions, enabling the robot to perform precise movements based on the workpiece data, thus providing a basis for subsequent grinding operations and ensuring grinding accuracy. Next, the control system controls the telescopic mechanism 34 to extend and retract based on the collected data, adjusting the distance between the two relatively positioned pneumatic files 33 to meet the workpiece placement requirements. The industrial robot moves the workpiece according to the positions of the two pneumatic files and the drilled holes on the workpiece, grinding the burrs at the drilled holes from both ends of the workpiece. Unlike traditional methods, there is no need to reverse and reposition the workpiece, greatly improving burr removal efficiency. During the grinding process, the funnel-shaped cover 5 collects the generated dust into the collection box 1 to prevent dust dispersion and maintain a clean working environment. At the same time, the air nozzle 392 sprays air, combined with the bristles 391, to clean the extended end of the telescopic mechanism 34, ensuring the normal operation of the telescopic mechanism 34.

[0035] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
