Innovation Solution
A deburring apparatus comprising a housing, a recovery rod, a tilting shaft, an elastic member, a holder, a rotary-to-rectilinear motion conversion mechanism, and a rotation transmission mechanism, which allows for controlled movement and separation of flange portions to mitigate vibration by converting rotational motion into linear motion and transmitting rotation to the tilting shaft, enabling effective cutting without excessive vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional deburring device uses a tilting shaft with flange portions forced together, then the device can maintain structural integrity, but vibration occurs during deburring operations
Solution Approach 1:
The invention converts the static forced-contact structure into a dynamic separated structure. The recovery rod and plunger mechanism enable the flange portions to separate during operation, transforming the rigid forced-contact state into a flexible separated state that reduces vibration while maintaining structural integrity through controlled motion.
Solution Approach 2:
The invention extracts the harmful vibration effect by introducing a separation mechanism. The recovery rod pulls the first flange portion away from the second flange portion, removing the source of vibration generated by forced contact between flanges, while the elastic member maintains overall structural coherence.
2Stability of the object's composition
If the recovery rod is forced toward the tilting shaft to maintain contact, then structural stability is maintained, but vibration and mechanical oscillation increase
Solution Approach 1:
The invention transforms the static forced-contact state into a dynamic separated state. The recovery rod mechanism allows the system to transition from a rigid forced-contact configuration to a flexible separated configuration, reducing mechanical oscillation while preserving structural stability through controlled separation and elastic restoration.
Solution Approach 2:
The invention converts the harmful forced-contact condition into a beneficial separated condition. By using the recovery rod to pull flange portions apart, the system eliminates the source of mechanical oscillation and vibration, transforming what was previously a harmful forced-contact state into a beneficial separated state that reduces harmful mechanical effects.
3Productivity
If the holder rotates relative to the tilting shaft during cutting, then cutting resistance can be utilized for motion conversion, but complex mechanical movement occurs
Solution Approach 1:
The invention introduces the plunger as an intermediary element between the holder and recovery rod. The plunger converts the rotational motion of the holder into linear motion that acts on the recovery rod, simplifying the mechanical movement chain while enabling effective utilization of cutting resistance for productive motion conversion.

AI summary
The present disclosure provides a deburring apparatus and a deburring method that does not require a positioning engagement part that is engaged with a fixed part of a machine tool. The deburring apparatus (10) includes a housing (1) with a shank (11), a transmission rod (3), a recovery rod (5), a tilting shaft (4), a spring (6), a holder (7), and a rotary-to-rectilinear motion conversion mechanism (9) with a plunger (8). The spring forces the recovery rod toward the tilting shaft. The holder for fixing the cutter (101) is arranged on the tilting shaft in a manner rotatable through a predetermined rotation angle. The rotary-to-rectilinear motion conversion mechanism separates the first flange portion from the second flange portion and brings the plunger into contact with the recovery rod on the tilting axis (43) when the holder rotates in a direction opposite to the rotation direction of the shank (11).
