Description

Technical Field

[0001] The utility model relates to the technical field of boring machine processing safety, in particular to a boring machine accessory capable of improving the production safety of cylinder sleeves. Background Art

[0002] A boring machine primarily uses a boring bar to drive a boring cutter, which then bores prefabricated holes in the workpiece. The inner wall of the cylinder liner must be smooth to reduce friction caused by the piston moving within the liner, so the boring cutter must machine the entire inner wall of the cylinder liner. During cylinder liner production, the boring cutter must penetrate deep into the liner for rotational machining. This results in the boring bar moving a long distance, placing significant pressure on the bar and causing it to vibrate during machining. If the vibration exceeds its tolerance limit, it can break, and flying parts can injure nearby workers. Utility Model Content

[0003] The purpose of the utility model is to provide a boring machine accessory that can improve the safety of cylinder liner production, so as to solve the problems raised in the above background technology.

[0004] The top end face of described sliding panel also is provided with an interlocking structure, and the interlocking structure of described sliding panel also is provided with an interlocking structure, and the interlocking structure of described sliding panel also is provided with an interlocking structure.

[0005] Preferably, the rotation groove is arranged around the guide cylinder, the cross section of the rotation groove is a T-shaped structure, and the inner walls at both ends of the control cylinder are rotatably connected to the rotation groove.

[0006] Preferably, the control plate is a T-shaped structure, both ends of the control plate pass through the guide cylinder, and a connecting spring is fixedly connected between the control plate and the outer side wall of the guide cylinder.

[0007] Preferably, the extrusion block and the control plate correspond one to one, the side end of the extrusion block is an arc-shaped structure, and the upper end of the connecting plate abuts against the side end of the extrusion block.

[0008] Preferably, a clamping groove is provided at the lower end of the control board, the rotating board is clamped in the clamping groove, and a pressure sensing head is fixedly connected to the inner wall of the upper end of the clamping groove.

[0009] Preferably, a scale is provided on the right side wall of the control cylinder, and a pointer is fixedly connected to the upper end of the guide cylinder.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: a guide cylinder is provided at the boring machine, and the boring bar moves inside the guide cylinder. When the boring bar vibrates during processing, the boring bar will squeeze the connecting wheel, thereby pushing the rotating plate to rotate. When the vibration amplitude of the boring bar exceeds the warning amplitude, the rotating plate will squeeze the pressure sensing head. At this time, the pressure sensing head senses the pressure and transmits the signal to the control motor of the boring machine, controlling the boring bar to stop processing, avoiding the boring bar from breaking, thereby ensuring the safety of the boring machine during processing.
