Abstract
Description
Technical Field
[0001] This utility model relates to the field of chamfering technology for welding and cutting, and more specifically, to a floating chamfering head and intelligent chamfering equipment equipped with a limit sensor. Background Technology
[0002] In the welding and cutting process, to improve the cutting quality of the workpiece, it is necessary to chamfer the edges of the cut workpiece to meet the requirements of subsequent processing techniques. Although manual chamfering is commonly used in current technologies, it is inefficient.
[0003] To address this, an automatic chamfering device was designed, equipped with a floating chamfering head for adaptive floating chamfering. However, because the floating direction of the floating chamfering head is a superposition of arbitrary swing direction and vertical movement, its degree of freedom is complex, making it impossible to effectively install limit sensors to monitor its vertical floating range. In particular, for floating chamfering heads equipped with spherical bearings, due to their wide omnidirectional swing range, ordinary limit switches cannot directly and effectively detect the combined motion range of the chamfering head composed of vertical floating and arbitrary swing direction. Utility Model Content
[0004] To solve the above problems, this utility model provides a floating chamfering head equipped with a limit sensor, comprising:
[0005] A sliding sleeve is provided inside which a drive shaft is connected to the bottom of the drive shaft, and the sliding sleeve is used to drive the drive shaft to move up and down.
[0006] A spherical bearing mechanism is fitted outside the sliding sleeve, and the spherical bearing mechanism is used to make the drive shaft swing in any direction;
[0007] A support rod is vertically installed at the top or bottom of the bearing in the spherical bearing mechanism;
[0008] A retaining mechanism, which cooperates with the support rod, is used to keep the support rod in contact with the top or bottom of the bearing;
[0009] A limit sensor is disposed adjacent to the support rod, the limit sensor being located at the sliding sleeve or the support rod; and

[0013] Optionally, a cross arm is provided on the top of the base, the base is disposed on the baffle, the first guide hole is opened at the cross arm, a circular limiting protrusion is provided on the side wall of the support rod, the elastic element is a spring, and the elastic element is disposed between the cross arm and the circular limiting protrusion.
[0014] Optionally, a guide rod is erected on the top of the base, the limiting member is a long strip structure, one end of the limiting member is connected to the top of the support rod, the limiting member has a second guide hole, the guide rod is inserted into the second guide hole, and the other end of the limiting member is positioned above the limiting sensor.
[0015] Optionally, the floating chamfering head further includes a sensor mounting base, which is an upright plate-shaped component. The sensor mounting base is detachably connected to the top of the baffle, and the limit sensor is a limit switch inserted into the plate of the sensor mounting base.
[0016] Optionally, the top of the drive shaft is provided with a plurality of mounting bolts, which connect the drive shaft to the flange. The support rod is inserted into one of the mounting bolts, the bottom of the support rod extends out of the mounting bolt and keeps in contact with the top of the bearing, and the top of the support rod extends out of the top of the mounting bolt and is connected to the limiting member.
[0017] Optionally, there are two limit sensors, which are arranged one above the other.
[0018] Optionally, the floating chamfering head further includes a spring mechanism that cooperates with the drive shaft. The spring mechanism is used to reset the drive shaft to a set position after the drive shaft moves up and down and / or swings in any direction.
[0019] In addition, this utility model also provides an intelligent chamfering device, including the aforementioned floating chamfering head.
[0020] The technical effects of this utility model include at least the following:
[0021] During the chamfering process, the chamfering cutter is driven by a drive shaft to chamfer the steel plate. A sliding sleeve drives the drive shaft to move up and down, while a joint bearing mechanism allows for oscillation in any direction. This creates a composite motion of the chamfering head's vertical movement and oscillation. For limit monitoring, a retaining mechanism is used to maintain contact between the support rod and the top or bottom of the bearing. This ensures that regardless of how the bearing in the joint bearing mechanism oscillates or rotates relative to the bearing seat, the support rod can move up and down relative to the sliding sleeve, achieving a complex motion. To simplify the process, limit sensors and limit components are respectively installed at the sliding sleeve and the support rod. When the limit component moves up and down relative to the spherical bearing mechanism, and the sliding sleeve moves up and down relative to the spherical bearing seat to a set limit (i.e., after the chamfering cutter contacts the steel plate and the chamfering device drives the chamfering cutter to move up and down relative to the spherical bearing seat), the limit component approaches the limit sensor and triggers the limit sensor, causing the automatic chamfering device to stop moving the sliding sleeve and chamfering cutter up and down. This effectively monitors the floating range of the chamfering cutter by installing a limit sensor. Attached Figure Description

[0034] See Figures 1 to 5 This embodiment provides a floating chamfering head equipped with a limit sensor, comprising:
[0035] A sliding sleeve 1 is provided inside which a drive shaft 14 is provided. A chamfering cutter 15 is connected to the bottom of the drive shaft 14. The sliding sleeve 1 is used to drive the drive shaft 14 to move up and down.
[0036] A joint bearing mechanism 2 is fitted outside the sliding sleeve 1, and the joint bearing mechanism 2 is used to make the drive shaft 14 swing in any direction.
[0037] The support rod 3 is vertically installed at the top or bottom of the bearing 21 of the joint bearing mechanism 2;
[0038] The retaining mechanism 4 cooperates with the support rod 3, and the retaining mechanism 4 is used to keep the support rod 3 in contact with the top or bottom of the bearing 21;
[0039] Limit sensor 5 is disposed adjacent to the support rod 3, and the limit sensor 5 is located at the sliding sleeve 1 or the support rod 3; and
[0040] The limiting component 6 is used to trigger the limiting sensor 5, and the limiting component 6 is disposed at the support rod 3 or the sliding sleeve 1.
[0041] It should be noted that the limit sensor 5 is located at the sliding sleeve 1 or the support rod 3, and the limit member 6 is located at the support rod 3 or the sliding sleeve 1; that is, when the limit sensor 5 is located at the sliding sleeve 1, the limit member 6 is located at the support rod 3, and when the limit sensor 5 is located at the support rod 3, the limit member 6 is located at the sliding sleeve 1.
[0042] In addition, the support rod 3 here can be vertically installed at the top or bottom of the bearing 21 of the joint bearing mechanism 2 as needed.
[0043] Alternatively, the drive shaft 14 can be an electric spindle, and the chamfering tool 15 is detachably connected to the electric spindle via a BT30 tool holder.
[0044] In addition, the limiting component 6 here can be a limiting block or a limiting piece, while the limiting sensor 5 can be a limiting switch. By blocking the limiting sensor 5 with the limiting component 6, the limiting sensor 5 can be triggered.
[0045] During the chamfering process, the chamfering cutter 15 is driven by the drive shaft 14 to chamfer the steel plate, and the drive shaft 14 is moved up and down by the sliding sleeve 1. At the same time, the joint bearing mechanism 2 allows for swinging in any direction, realizing a composite motion of up-and-down floating and swinging of the chamfering head. When performing limit monitoring, the retaining mechanism 4 cooperates with the support rod 3 to keep the support rod 3 in contact with the top or bottom of the bearing 21. In this way, no matter how the bearing 21 of the joint bearing mechanism 2 swings or rotates relative to the bearing seat, the support rod 3 can move up and down relative to the sliding sleeve 1, realizing the simplification of complex motion. The process involves setting the limit sensor 5 and the limit member 6 at the sliding sleeve 1 and the support rod 3, respectively. When the sliding sleeve 1 moves up and down relative to the joint bearing mechanism 2, and the sliding sleeve 1 moves up and down relative to the joint bearing seat to a set limit (i.e., after the chamfering cutter 15 contacts the steel plate), and the chamfering device drives the chamfering cutter 15 to move up and down relative to the joint bearing seat, the limit member 6 approaches the limit sensor 5 and triggers the limit sensor 5. This stops the automatic chamfering device from driving the sliding sleeve 1 and the chamfering cutter 15 to continue moving up and down, effectively monitoring the floating range of the chamfering cutter 15 using the limit sensor 5.
[0046] Furthermore, a retaining 12 is provided on the top of the sliding sleeve 1, the limiting sensor 5 is located at the retaining 12, the support rod 3 passes through the retaining 12 and maintains contact with the top of the bearing 21, and the limiting member 6 is connected to the support rod 3.
[0047] By placing the limit sensor 5 and the limit member 6 on the baffle 12 above the sliding sleeve 1, the limit sensor 5 is kept away from the chamfering cutter 15, thus preventing damage to the limit sensor 5.
[0048] Furthermore, the retaining mechanism 4 includes a base 41 and an elastic member 44. The base 41 is connected to the baffle 12. The base 41 has a first guide hole 45. The top end of the support rod 3 passes through and extends out of the first guide hole 45. The limiting member 6 is connected to the top end of the support rod 3. The elastic member 44 cooperates with the base 41 and the support rod 3 respectively. The elastic member 44 is used to push the support rod 3 downward.
[0049] Furthermore, a cross arm 42 is provided on the top of the base 41, the base 41 is provided on the eaves 12, the first guide hole 45 is opened at the cross arm 42, a circular limiting protrusion 31 is provided on the side wall of the support rod 3, the elastic member 44 is a spring, and the elastic member 44 is provided between the cross arm 42 and the circular limiting protrusion 31.
[0050] A spring is used between the cross arm 42 and the annular limiting protrusion 31 to ensure that the spring always exerts downward pressure on the annular limiting protrusion 31, thereby keeping the support rod 3 in contact with the top or bottom of the bearing 21.
[0051] Furthermore, a guide rod 43 is erected on the top of the base 41, and the limiting member 6 is a long strip structure. One end of the limiting member 6 is connected to the top of the support rod 3. The limiting member 6 has a second guide hole 61, and the guide rod 43 is inserted into the second guide hole 61. The other end of the limiting member 6 is positioned above the limiting sensor 5.
[0052] The guide rod 43 ensures that the limiting member 6 moves up and down relative to the sliding sleeve 1. In addition, the elongated structure of the limiting member 6 increases its effective length, enabling it to accurately trigger the limiting sensor 5.
[0053] Furthermore, the floating chamfering head also includes a sensor mounting base 13, which is a vertically arranged plate-shaped component. The sensor mounting base 13 is detachably connected to the top of the baffle 12. The limit sensor 5 is a limit switch, which is inserted into the plate of the sensor mounting base 13.
[0054] The limit sensor 5 is fixed using the sensor mounting base 13.
[0055] Furthermore, the top of the drive shaft 14 is provided with a plurality of mounting bolts 7, which connect the drive shaft 14 to the flange 12. The support rod 3 is inserted into one of the mounting bolts 7, the bottom of the support rod 3 extends out of the mounting bolt 7 and keeps in contact with the top of the bearing 21, and the top of the support rod 3 extends out of the top of the mounting bolt 7 and is connected to the limiting member 6.
[0056] By inserting the support rod 3 into a mounting bolt 7, it is not necessary to open mounting holes for the support rod 3 at the drive shaft 14 and the flange 12. Only a through hole needs to be opened at the mounting bolt 7, which simplifies the installation of the support rod 3 and saves space at the drive shaft 14.
[0057] Furthermore, there are two limit sensors 5, which are arranged one above the other.
[0058] It should be noted that the two limit sensors 5 here can be set with a gap between them, or the two limit sensors 5 can be set adjacent to each other.
[0059] When the two limit sensors 5 are spaced apart vertically, and the limit member 6 is placed between the two limit sensors 5, the two limit sensors 5 serve as the upper limit position and lower limit position of the chamfering tool 15 floating vertically.
[0060] When two limit sensors 5 are set adjacent to each other, the limit member 6 is located above or below the two limit sensors 5. In this way, the limit sensor 5 adjacent to the limit member 6 serves as the working indicator sensor. When the limit member 6 triggers this sensor, the chamfering cutter 15 floats within the normal floating range. When the limit member 6 triggers the other limit sensor 5, the chamfering cutter 15 has reached the limit position. At this time, the automatic chamfering equipment can drive the chamfering cutter 15 to lift or reset to the normal working range.
[0061] Furthermore, the floating chamfering head also includes a spring mechanism that cooperates with the drive shaft 14. The spring mechanism is used to reset the drive shaft 14 to a set position after the drive shaft 14 moves up and down and / or swings in any direction.
[0062] Preferably, the elastic mechanism includes a radial reset mechanism 81 and a vertical reset mechanism 82;
[0063] The radial reset mechanism 81 includes: a circular base and a plurality of elastic pushing mechanisms. The circular base is connected to the base 41. The circular base is located below the joint bearing mechanism 2. The bottom of the drive shaft is inserted into the circular base. The plurality of elastic pushing mechanisms are arranged at intervals along the circumference of the drive shaft at the circular base. Each elastic pushing mechanism pushes the drive shaft radially.
[0064] The vertical reset mechanism 82 includes: a guide sleeve, a baffle, multiple guide posts, multiple upper push springs, and multiple lower pressure springs. The guide sleeve is disposed within the bearing 21 of the spherical bearing mechanism 2, and the drive shaft is fixed within the guide sleeve. The guide sleeve is used to move up and down within the bearing 21. The baffle covers the top surface of the guide sleeve and is connected to it. A through hole is provided on the top surface of the baffle, and the drive shaft is inserted into the through hole. Multiple guide posts are vertically inserted into the baffle, and the bottom end of each guide post is connected to the bearing seat of the spherical bearing mechanism 2. A limit mechanism is provided at the top of each guide post, and the baffle is used to move up and down along the guide post. Multiple upper push springs are correspondingly sleeved on the outside of the guide posts, and the upper push springs are placed between the baffle and the bearing seat. The upper push springs are used to push the baffle upwards. Multiple lower pressure springs are correspondingly sleeved on the outside of the guide posts, and the lower pressure springs are placed between the baffle and the limit mechanism. The lower pressure springs are used to press the baffle downwards, and the limit mechanism is used to restrict the upward movement of the lower pressure springs.
[0065] In addition, this embodiment also provides an intelligent chamfering device, including the aforementioned floating chamfering head. Since the technical effects achieved by this intelligent chamfering device are the same as those of the aforementioned floating chamfering head, the intelligent chamfering device will not be further explained.
[0066] Although the present invention has been disclosed above, its scope of protection 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 invention, and all such changes and modifications will fall within the scope of protection of the present invention.
