Description

Technical Field

[0001] This invention relates to the field of chamfering tool technology, and more particularly to a chamfering anti-splash combination tool. Background Technology

[0002] In actual high-end mechanical manufacturing, after drilling parts, it is often necessary to chamfer the edges of the drilled holes to improve the processing quality. Chamfering tools are mainly used for chamfering the edges of holes, deburring, countersunk holes, and forming tapered holes. When performing chamfering, it is necessary to avoid damage from chamfering debris. Current chamfering anti-splash combination tools are not convenient for automatic control to prevent the accumulation of splashes, nor are they convenient for automatic control to prevent secondary burrs. Traditional fixed tools, especially when the chamfering angle is small, are prone to secondary burrs, which further affects the chamfering quality. It is not convenient to automatically control the trimming after chamfering, and it is also not convenient to detect tool eccentricity, which can easily affect the tool processing quality.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figures 1 to 9 :

[0034] This invention proposes a chamfered anti-splash combination tool, including a tool holder mounting component 1, on which an anti-splash device 2 is installed; the anti-splash device 2 is used to prevent cutting splashes; an eccentric indicator component 3 is installed inside the tool holder mounting component 1; the eccentric indicator component 3 and the tool holder mounting component 1 are concentric; a torsion chamfer component 4 is installed at the bottom of the tool holder mounting component 1; the torsion chamfer component 4 is used to prevent secondary burrs; the tool holder mounting component 1 includes: a tool holder 101 and an indicator light 1011, the indicator light 1011 is fixedly installed on the tool holder 101; the bottom of the tool holder 101 is an octagonal column structure.

[0035] In this embodiment, the tool holder mounting component 1 further includes: a sliding sleeve 102, a spring 1021, a mounting head 103, and a retaining ring 104. The sliding sleeve 102 is slidably sleeved on the bottom of the tool holder 101; the spring 1021 is sleeved inside the sliding sleeve 102; the spring 1021 is connected between the sliding sleeve 102 and the bottom of the tool holder 101; a button battery is provided at the bottom of the tool holder 101; the mounting head 103 is threadedly connected to the bottom of the sliding sleeve 102; the retaining ring 104 is fixedly sleeved on the mounting head 103; the bottom of the mounting head 103 has a beveled structure; and a wire hole is provided on the tool holder 101. The tool holder mounting component 1 further includes: a painted surface 1041, which is provided on the bottom side of the mounting head 103; the painted surface 1041 is used to indicate wear; the rotational contour of the painted surface 1041 is smaller than the rotational contours of the first chamfered block 401 and the second chamfered block 402; the splash guard 2 includes: a fixing bracket 201 and a housing 202, the fixing bracket 201 is fixedly sleeved on the tool holder 101; the housing 202 is fixedly installed on the bottom of the fixing bracket 201, and the housing 202 is provided with a through groove; the fixing bracket 201 is sleeved on the mounting head 103; the housing 202 is sleeved on the retaining ring 104. The outer side; a groove is provided on the sleeve 202 for the flow of cutting fluid; the sleeve 202 is used to prevent cutting debris from splashing; the splash guard 2 also includes: a rubber ring 203, which is fixedly installed at the bottom of the sleeve 202, and the rubber ring 203 has a beveled structure; the rubber ring 203 is used to adhere to the workpiece. The splash guard 2 can realize automatic control of splash prevention, which can effectively avoid damage from splashing objects. At the same time, it can realize automatic control of protection during chamfering. After chamfering is completed, the cutting debris inside the sleeve 202 can be automatically discharged to prevent internal cutting of the sleeve 202. With excessive debris, the structure is more reasonable, avoiding blockage that could affect the discharge of chamfered chips. The structure is simple to control, making it more flexible to use. It avoids the impact of factors such as forgetting to clean the cutting process. At the same time, the paint surface 1041 allows workers to more intuitively understand the wear or detachment of the chamfered part 4. The wear of the paint surface 1041 can be used as an indicator, making it more intuitive. As drilling is completed, when the tool holder 101 is lifted, the spring 1021 can push the retaining ring 104 down to push out any accumulated cutting chips inside the housing 202, preventing accumulation.

[0036] In this embodiment, the eccentric indicator 3 includes: a rotating mounting block 3011 and a rotary arm 301. The rotating mounting block 3011 is fixedly mounted inside the sliding sleeve 102. The rotary arm 301 is rotatably mounted on the rotating mounting block 3011. The rotary arm 301 and the rotating mounting block 3011 are electrically bonded together. The eccentric indicator 3 also includes: a swing ball 302 and a contact ring 303. The swing ball 302 is fixedly mounted at the bottom of the rotary arm 301. The swing ball 302 is used for counterweight. The contact ring 303 is fixedly sleeved inside the sliding sleeve 102. The swing ball 302 is located inside the contact ring 303. A gap is provided between the contact ring 303 and the swing ball 302. The rotating mounting block 3011, the indicator light 1011, the contact ring 303, and the button battery at the bottom of the mounting handle 101 are connected in series by a wire. The swing ball 302 is used to connect with the contact ring 303. The device uses an eccentricity indicator 3 to indicate eccentricity during the rotation and swing of the mounting head 103. This eccentricity detection eliminates the need for manual measurement, preventing undetected eccentric deformation of the mounting head 103 after long-term use. It enables automatic detection and alerts, improving safety while ensuring actual chamfering accuracy. The alert method is simple and intuitive, utilizing the dynamic centrifugal force during high-speed rotation of the chamfer to amplify accuracy deviations and increase detection sensitivity. It can quickly detect deformation of the mounting head 103 itself or movement due to factors such as insecure workpiece clamping. Furthermore, the compact structure ensures that if the eccentricity deviation is large, the centrifugal forces on the rotating arm 301 and the swing ball 302 will no longer be balanced. The rotating arm 301 will rotate on the rotating mounting block 3011, at which point the swing ball 302 will contact the electrical contact ring 303 for power connection, thus controlling the indicator light 1011 to illuminate.

[0037] In Embodiment 2, based on Embodiment 1, the twist chamfering component 4 includes: a first chamfering block 401 and a first spring piece 4011. The first chamfering block 401 is provided with a chamfering blade; the bottom of the first chamfering block 401 is rotatably mounted on the mounting head 103; the chamfering blade on the first chamfering block 401 is used to trim the upper edge of the chamfer; the top of the first chamfering block 401 is used for rotational swinging; the first spring piece 4011 is fixedly mounted on the side of the first chamfering block 401; the end of the first spring piece 4011 is mounted on the mounting head 103; the twist chamfering component 4 further includes: a second chamfering block 402, the top of the second chamfering block 402 is rotatably mounted on the mounting head 103; the second chamfering block The second chamfering block 402 is equipped with a chamfering blade; the chamfering blade on the second chamfering block 402 is used to trim the lower edge of the chamfer; the bottom of the second chamfering block 402 is used for rotation and swinging; the torsion chamfering component 4 also includes: a second spring 4021, the second spring 4021 is fixedly installed on the side of the second chamfering block 402, and the end of the second spring 4021 is installed on the mounting head 103; the second spring 4021 is used to elastically support the second chamfering block 402. The torsion chamfering component 4 can realize rapid standard chamfering cutting, and at the same time, the torsion chamfering component 4 can prevent secondary burrs from being generated on the upper and lower edges of the chamfer during actual chamfering, and can realize automatic control of elastic rotation to adjust the chamfering angle. With the lower downward pressure when lifting and twisting the chamfering piece 4, burrs are avoided, and normal processing efficiency is not affected. It can achieve rotation and fit with the upper and lower edges of the chamfer. At the same time, the angle changes after rotation, ensuring the quality of deburring. The structure is more reasonable and no further finishing is required. It is especially effective in processing environments with large chamfer depths, effectively improving processing quality. The first chamfering block 401 and the second chamfering block 402 with opposite rotation directions automatically control the chamfering and deburring of the upper and lower edges after chamfering. When the mounting head 103 moves down and drives the first chamfering block 401 and the second chamfering block 402 to fit with the edge of the drill hole, under the stop of the drill hole edge, the first chamfering block 401 and the second chamfering block 402 retract and compress the first spring 4011 and the second spring 4021 respectively to achieve accurate chamfering turning precision. After the chamfering is completed, when the mounting head 103 is slowly pulled out, the mounting head 103 no longer provides downward pressure. With the elastic compression of the first spring 4011 and the second spring 4021, the first chamfering block 401 and the second chamfering block 402 rotate respectively to fit the upper and lower edges of the chamfer, ensuring that the upper and lower edges of the chamfer are deburred. It has better adaptability to different hole diameters. At the same time, the gradually rotating first chamfering block 401 and the second chamfering block 402 can avoid the recurrence of roughness, and the trimmed edge is smoother.

[0038] The working principle of this embodiment is as follows: First, after the tool holder 101 is installed on the tool holder, when the tool holder 101 drives the mounting head 103 to move down close to the edge of the drill hole, the spring 1021 is compressed, and the sleeve 202 can move down to cover the outside of the torsion chamfering member 4. The chips generated by the torsion chamfering member 4 can be blocked and protected. At the same time, as the drilling is completed, when the tool holder 101 is lifted, the spring 1021 can push the retaining ring 104 down to push out any accumulated cutting chips inside the sleeve 202, preventing accumulation. Meanwhile, during the actual use cycle of the first chamfering block 401 and the second chamfering block 402... Due to factors such as length, excessive wear will cause the chamfered edge to rub against the paint surface 1041 as it shrinks. Wear on the paint surface 1041 can be quickly observed manually, allowing for timely repairs. As the mounting head 103 rotates to chamfer, the oscillating ball 302 is also driven to rotate. Under standard conditions, the oscillating ball 302 remains in a fixed position. However, if the mounting head 103 experiences eccentric deformation, the rotating mounting block 3011 cannot remain concentric with the mounting tool holder 101 during rotation. If the eccentric deviation is large, the centrifugal forces on the rotating arm 301 and the oscillating ball 302 will no longer be balanced, causing the rotating arm 301 to... 1. The rotating head 103 will rotate on the rotating mounting block 3011. At this time, the oscillating ball 302 will be in contact with the contact ring 303 to receive power, thereby controlling the indicator light 1011 to light up, which can be observed by the operator in a timely manner. When the mounting head 103 moves down and drives the first chamfering block 401 and the second chamfering block 402 to fit against the edge of the drill hole, under the stop at the edge of the drill hole, the first chamfering block 401 and the second chamfering block 402 will retract and compress the first spring 4011 and the second spring 4021 respectively. After retraction, the first chamfering block 401 and the second chamfering block 402 can be pressed down with the rotation of the mounting head 103 to achieve accurate chamfering. As the chamfering is completed... When the mounting head 103 is slowly pulled out, the mounting head 103 no longer provides downward pressure. With the elastic compression of the first spring 4011 and the second spring 4021, the first chamfer block 401 and the second chamfer block 402 rotate respectively. By using the opposite rotation of the first chamfer block 401 and the second chamfer block 402, they are respectively attached to the upper and lower edges after chamfering. At this time, the mounting head 103 continues to rotate. At the same time, as the upward distance of the mounting head 103 increases, the first chamfer block 401 and the second chamfer block 402 will gradually rotate back to adapt to the upper and lower edges of the chamfer, ensuring that the upper and lower edges of the chamfer are deburred.
