Description

Technical Field

[0001] The utility model relates to the technical field of orifice chamfering, and particularly to a floating chamfering head and an automatic chamfering device. Background Art

[0002] Before welding holes on a board surface, it is common to chamfer the hole walls to ensure the subsequent welding quality. For chamfering operations on holes on a general board surface, manual processing can be used to complete.

[0003] However, for a perforated plate with a huge number of holes, the labor intensity of manual chamfering also increases correspondingly, and the quality stability is poor.

[0004] In addition, although robots or automatic chamfering devices are also used for automatic chamfering operations in the prior art, due to factors such as the positioning accuracy of the robot and the error accumulation between multiple components, the chamfering tool of the automatic chamfering device cannot be in complete contact with the hole wall, resulting in situations where some hole walls are not chamfered, the chamfering of the hole wall is severely eccentric or severely inclined, and even the automatic chamfering accuracy is not as good as the manual chamfering accuracy.

[0011] Optionally, the base is a shell structure, and the movable seat is a rotary body structure member and is inserted into the base.

[0012] The first limiting structure member includes:

[0025] Optionally, the driving mechanism is a pneumatic motor.

[0026] In addition, the present utility model also provides an automatic chamfering device, including the floating chamfering head described above.

[0027] The technical effects of the present utility model at least include:

[0028] The utility model utilizes the execution end of the automatic chamfering device to approach the chamfering hole of the hole plate to be chamfered. At the same time, the driving mechanism can be started to rotate the chamfering tool, and the chamfering tool is continued to chamfer the specified hole through the execution end. When the chamfering tool is not concentric with the hole, by using the characteristic that the bottom end of the movable seat can swing towards any side direction only within a set angle range by the first limiting structural component, the chamfering tool drives the movable seat to swing towards the corresponding side direction, realizing the floating swing of the chamfering tool, so that the chamfering tool is in full contact with the hole wall. Under the rotation of the driving mechanism, the hole wall obtains a relatively uniform chamfer. And during this process, the elastic deformation member always stably pushes the movable seat downward. Due to the limitation of the first limiting structural component, the bottom end of the movable seat can only swing towards any side direction within a set angle range. When the movable seat swings, the elastic deformation member undergoes slight elastic deformation, and the movable seat will not move upward too much, thus avoiding excessive deformation of the elastic deformation member and ensuring the smooth progress of the chamfering operation. After the chamfering operation is completed, the elastic deformation member pushes the movable seat downward to reset the movable seat. In this way, through the mutual cooperation of the base, the movable seat, the elastic deformation member, the driving mechanism and the chamfering tool, the floating chamfering of the holes on the hole plate is realized, ensuring that the chamfering tool of the automatic chamfering device is in full contact with the hole wall, preventing the situation of serious eccentricity or serious inclination of the hole wall chamfer, and avoiding the occurrence of un-chamfered parts of the hole wall.

[0040] See Figures 1 to 4 , this embodiment provides a floating chamfering head, and the floating chamfering head includes:

[0041] A base 1, disposed at the execution end of the automatic chamfering device;

[0042] A movable seat 2, disposed below the base 1, and the movable seat 2 is in clearance fit with the base 1 through a first limit structural member 3. Through the limitation of the first limit structural member 3, the bottom end of the movable seat 2 can only swing towards any side direction within a set angle range;

[0043] A resilient deformation member 5, cooperating with the movable seat 2 and the base 1 respectively, and the resilient deformation member 5 is used to push the movable seat 2 downward; and

[0044] A driving mechanism 6, disposed below the movable seat 2, the driving mechanism 6 is connected to the movable seat 2, and the driving mechanism 6 is used to drive the chamfering tool 61 below it to rotate.

[0045] It should be noted that the driving mechanism 6 in this embodiment can be a pneumatic motor or a driving motor, as long as it can drive the chamfering tool 61 below it to rotate.

[0046] In addition, the first limiting structure member 3 may be an eaves structure stacked on top of each other. One form is, for example, the circular groove 31 and the circular eaves 32 mentioned in the following text of this embodiment. Another form may be that the movable seat 2 is also a housing structure, the bottom of the base is a cylindrical structure, and an eaves is provided at its bottom end. The eaves structure is stuck inside the movable seat 2, and the eaves and the movable seat 2 are in clearance fit, so that the movable seat 2 can swing relative to the base 1 in any direction, that is, "the bottom end of the movable seat 2 swings only within a set angle range towards any side direction".

[0047] In addition, the elastic deformation member 5 may be a spring, a disc spring or a sealed cylinder piston structure. As long as the elastic deformation member 5 can achieve elastic reset after being compressed.

[0048] In addition, the set angle range may be within 0 to 8°, preferably within 2° to 5°.

[0049] In addition, the swing in any side direction may be a swing in one direction among forward, backward, left, and right, or a swing in a certain direction such as left front, left rear, right front, etc.

[0050] During use, the execution end of the automatic chamfering device is brought close to the chamfering hole of the hole plate. At the same time, the driving mechanism 6 can be started to rotate the chamfering tool 61, and the chamfering tool 61 is used to chamfer the specified hole through the execution end. When the chamfering tool 61 is not concentric with the hole, taking advantage of the characteristic that the bottom end of the movable seat 2 can swing only within a set angle range towards any side direction by the first limiting structure member 3, the chamfering tool 61 drives the movable seat 2 to swing in the corresponding side direction, realizing the floating swing of the chamfering tool 61, so that the chamfering tool 61 is in full contact with the hole wall. Under the rotation of the driving mechanism 6, the hole wall obtains a relatively uniform chamfer. And during this process, the elastic deformation member 5 always stably pushes the movable seat 2 downward. Due to the limitation of the first limiting structure member 3, the bottom end of the movable seat 2 swings only within a set angle range towards any side direction. When the movable seat 2 swings, the elastic deformation member 5 undergoes slight elastic deformation, and the movable seat 2 will not move upward by too large an amplitude, thus avoiding excessive deformation of the elastic deformation member 5 and ensuring the smooth progress of the chamfering operation. After the chamfering operation is completed, the elastic deformation member 5 pushes the movable seat 2 downward to reset the movable seat 2. In this way, through the mutual cooperation of the base 1, the movable seat 2, the elastic deformation member 5, the driving mechanism 6 and the chamfering tool 61, floating chamfering of the holes on the hole plate is realized, ensuring that the chamfering tool 61 of the automatic chamfering device is in full contact with the hole wall, preventing the situation of serious eccentricity or serious inclination of the hole wall chamfer, and avoiding the occurrence of non-chamfered parts of the hole wall.

[0051] It should be noted that although the chamfered hole wall machined by the chamfering tool 61 is in a slightly inclined state when the chamfering tool 61 is not concentric with the hole, for example, inclined by 2° to 5°, this inclined state is only within the set angle range, so as to ensure that the chamfering tool 61 and the circumferential surface of the hole wall are in contact, so as to ensure that any point at the top of the hole wall is chamfered. And chamfering is usually an auxiliary process before hole plate welding, and its tolerance requirements are not high, which fully meets the requirements of conventional hole chamfering.

[0052] See Figures 1 to 4 , further, the floating chamfering head also includes an extension connecting member 7, which is arranged between the driving mechanism 6 and the movable seat 2, and the extension connecting member 7 is used to extend the distance between the movable seat 2 and the driving mechanism 6.

[0053] When the bottom end of the movable seat 2 swings towards a side direction, such as the left side, the right side of the first limit structure member 3 becomes the fulcrum, and the movable seat 2, the driving mechanism 6 and the chamfering tool 61 form a lever. The longer the lever is, the easier it is for the chamfering tool 61 at the distal end of the lever to perform floating swing, improving the swing sensitivity of the chamfering tool 61.

[0054] For this reason, the extension connecting member 7 is added between the driving mechanism 6 and the movable seat 2, so as to extend the distance between the movable seat 2 and the driving mechanism 6. Improve the floating swing sensitivity of the chamfering tool 61, so that the chamfering tool 61 is easier to be in full contact with the hole wall.

[0055] In addition, the extension connecting member 7 can be a rod member, a sleeve member, or a steel beam structure, as long as it can extend the distance between the movable seat 2 and the driving mechanism 6.

[0056] See Figures 1 to 4 , further, the base 1 is of a shell structure, and the movable seat 2 is a rotary body structure member and is inserted into the base 1.

[0057] The first limit structure member 3 includes:

[0058] A circular groove 31, which is arranged in the base 1; and

[0059] A circular ring retaining edge 32, which is sleeved on the side wall of the movable seat 2, and the circular ring retaining edge 32 is arranged in the circular groove 31 with a gap, and the circular groove 31 is used to prevent the circular ring retaining edge 32 from disengaging from it.

[0060] By using the circular ring retaining edge 32 arranged in the circular groove 31 with a gap, it can not only prevent the movable seat 2 from detaching from the base 1, but also enable the bottom end of the movable seat 2 to swing towards any side direction only within the set angle range.

[0061] See Figures 1 to 4 Furthermore, the floating chamfering head further includes a second limiting structure 4, which is respectively arranged at the base 1 and the movable seat 2, and the second limiting structure 4 is used to prevent the movable seat 2 from rotating relative to the base 1.

[0062] See Figures 1 to 4 Furthermore, the second limiting structure 4 includes:

[0063] A plurality of first through holes 41, evenly distributed on the circumference of the circular ring eaves 32; and

[0064] A plurality of pins 42, evenly distributed along the circumference of the circular groove 31 on the bottom surface of the circular groove 31, the pins 42 are inserted into the first through holes 41 one by one, and the pins 42 and the first through holes 41 are in clearance fit.

[0065] By inserting the pins 42 into the first through holes 41 one by one, the rotation of the movable seat 2 relative to the base 1 can be prevented. Moreover, the pins 42 and the first through holes 41 are in clearance fit, which can prevent the pins 42 from hindering the swing of the bottom end of the movable seat 2.

[0066] See Figures 1 to 4 Furthermore, the base 1 includes:

[0067] The base 1 body, which is a shell structure, has an open end at its lower end, and the circular groove 31 is opened at the open end; and

[0068] A bottom plate 13, with a second through hole 132 opened in the center, the movable seat 2 is inserted into the second through hole 132, a plurality of the pins 42 are evenly distributed around the second through hole 132 on the top surface of the bottom plate 13, the bottom plate 13 covers the open end, and the bottom plate 13 is detachably connected to the base 1 body.

[0069] By using the detachable connection between the bottom plate 13 and the base 1 body, it is convenient to install the circular ring eaves 32 in the circular groove 31 and improve the assembly efficiency.

[0070] Preferably, the bottom plate 13 is a circular ring-shaped structural member.

[0071] See Figures 1 to 4 Furthermore, a first circular protrusion 131 is arranged at the bottom plate 13, the first circular protrusion 131 is arranged around the second through hole 132, the first circular protrusion 131 protrudes upward, and a plurality of the pins 42 are evenly distributed along the circumference on the top surface of the first circular protrusion 131;

[0072] The outer edge of the circular ring retaining edge 32 is provided with a second circular ring protrusion 321, the second circular ring protrusion 321 protrudes downward, and the second circular ring protrusion 321 is sleeved outside the first circular ring protrusion 131.

[0073] By providing a first circular ring protrusion 131 at the bottom plate 13, a second circular ring protrusion 321 is provided at the outer edge of the circular ring retaining edge 32, and the second circular ring protrusion 321 is sleeved outside the first circular ring protrusion 131, so that the first circular ring protrusion 131 and the second circular ring protrusion 321 are used to play an auxiliary positioning role for the movable seat 2.

[0074] See Figures 1 to 4 , further, the elastic deformation member 5 is a spring.

[0075] See Figures 1 to 4 , further, the driving mechanism 6 is a pneumatic motor. When the pneumatic motor stalls due to overload, a pressure relief valve is provided in the corresponding pneumatic pipeline, so as to protect the pneumatic motor. When the driving motor stalls due to overload, the driving motor will be damaged or even burned.

[0076] See Figures 1 to 4 , further, this embodiment also provides an automatic chamfering device, including the floating chamfering head. The automatic chamfering device can be a robotic arm type robot.

[0077] Since the technical effects obtained by the automatic chamfering device are the same as those of the floating chamfering head, the automatic chamfering device will not be further explained.

[0078] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the protection scope of the present invention.
