[0018] The utility model is further described below in conjunction with the accompanying drawings: As shown in the figure, the automatic deburring device for circumferential wall holes includes a base plate 1 and a crossbeam 2, and also includes a clamp assembly 3, which is arranged on the base plate and is used to contact the circumferential outer wall of the workpiece 9; the deburring assembly 4 is installed on the crossbeam and has a pressure head 42 driven by a power source 41, and the pressure head makes a linear reciprocating motion along the radial direction of the workpiece and is used to at least partially contact the hole 91 of the workpiece to flatten the burrs. After the workpiece is positioned by the clamp assembly (it does not need to be clamped too tightly, just contact it, just do preliminary positioning), the pressure head of the deburring assembly is extended to contact the hole on the workpiece to flatten the burrs around the hole. The pressure head can be driven by a cylinder to extend and retract. Multiple pressure heads can be set, which can be set according to the number of holes, generally four, and can be extended and retracted synchronously. It should be noted that for ease of use, the column 15 can be designed as a liftable column, and the structure of CN206144922U can be selected.

[0019] In this embodiment, as shown in the figure, the pressure head includes a rod body 40, and the outer wall of the rod body is provided with a chamfered portion 421 for contacting the hole. By flattening the chamfered portion, the use effect is better.

[0020] In this embodiment, as shown in the figure, the power source is a linear drive, which can be a hydraulic cylinder or a pneumatic cylinder.

[0021] In this embodiment, as shown in the figure, the deburring assembly further includes a housing, the housing includes a chassis 43, a radially arranged slide groove 431 is provided in the chassis, a sliding block 432 is provided in the slide groove, the rod body is connected to the sliding block and part of the rod body extends out of the chassis. The sliding block is provided with the rod body, and when it moves, it will also drive the rod body to move.

[0022] In this embodiment, as shown in the figure, a driving rod 45 connected to the power source is further included, the driving rod is provided with a first push block 451, and the slider is provided with a second push block 433 that matches the inclined surface of the first push block. The driving rod can be provided with multiple first push blocks to push the second push blocks on different sliders forward to achieve synchronous deburring of multiple holes.

[0023] In this embodiment, as shown in the figure, a receiving groove 46 is further provided in the chassis, and an elastic member 461 is provided in the receiving groove for applying force to push the slider backward, so as to reset the pressure head.
