Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0029] Example 1

[0030] See Figure 1As shown, this embodiment provides a floating force-controlled calibration and limiting chamfering processing device, which includes: a moving mechanism 100; a chamfering mechanism 200, the chamfering mechanism 200 including a drive shaft 220 and at least one cutter 230, the drive shaft 220 being connected to the moving mechanism 100 and moving within the processing space via the moving mechanism 100, the at least one cutter 230 being connected to the working end of the drive shaft 220 and rotatable around the axis of the drive shaft 220 to chamfer the edge of the element 500 to be processed; and a calibration mechanism 300, the calibration mechanism 300 being sleeved on the drive shaft 220 and arranged around the at least one cutter 230, the calibration mechanism 300 including a fixed seat 310 and an adjusting seat 320, the fixed seat 310 being connected to the drive shaft 220, and including a first body 312 and a pointer. 313, the pointer 313 is connected to the outer surface of the first body 312 and is spaced apart from the outer surface of the first body 312 in the cross-sectional direction of the first body 312; the adjustment seat 320 includes a second body 321 and a support component 322. The second body 321 is slidably connected to the first body 312 along its height direction. The outer wall of the second body 321 is provided with a plurality of scale protrusions 3214 arranged along its height direction. The pointer 313 abuts against the scale protrusions 3214 to mark the preset chamfering depth. The support component 322 is connected to the bottom of the second body 321 and includes a plurality of bullseye balls 3222. The bullseye balls 3222 roll and support the surface of the element 500 to be processed to form a hard limiting structure for the actual chamfering depth.

[0031] The floating force-controlled calibration and limiting chamfering processing equipment described in this embodiment uses a moving mechanism 100 to drive the chamfering mechanism 200 and the calibration mechanism 300 to move synchronously. The chamfering depth is precisely adjusted through the cooperation between the pointer 313 and the scale protrusion 3214 in the calibration mechanism 300. Simultaneously, a hard limiting structure for a fixed chamfering depth is formed by the support component 322, thereby ensuring that the cutter 230 can perform a stable chamfering process on the workpiece 500 during the chamfering process. Compared to conventional chamfering processing technologies, this application has higher adjustment accuracy and a more stable limiting structure, making it suitable for high-precision machining scenarios. Furthermore, it also boasts advantages such as high controllability, ease of operation, high product yield, and stable production process, making it a novel chamfering processing technology with broad application prospects.

[0032] See Figure 1As shown, to achieve the connection between the various structures, this embodiment also includes a support mechanism 400, which provides an installation and connection platform for the moving mechanism 100, the chamfering mechanism 200, and the calibration mechanism 300. The support mechanism 400 includes a mounting surface 410 and a processing table 420. The moving mechanism 100 and the processing table 420 are respectively disposed on the mounting surface 410. The processing table 420 is provided with at least one fixing block 421 to fix the component 500 to be processed. Further, in this embodiment, the moving mechanism 100 includes a robotic arm 110 and a floating force control module 120. The floating force control module 120 is disposed at the working end of the robotic arm 110, and the chamfering mechanism 200 is connected to the working end of the floating force control module 120 through a connecting frame 210. The floating force control module 120 can realize real-time automatic adjustment of the specific chamfering force, thereby improving the processing stability of this equipment.

[0033] See Figure 2 and Figure 3 As shown, in this embodiment, the chamfering mechanism 200 is connected to the working end of the floating force control module 120 via a connecting frame 210. Specifically, the connecting frame 210 is rotatably fixed to the working end of the floating force control module 120, and the drive shaft 220 passes through the connecting frame 210, thereby improving its flexibility of use. In this embodiment, the drive shaft 220 is preferably a rotary electric shaft, which can drive the cutter 230 connected to its working end to rotate via electrical control, thereby realizing the chamfering process of the edge of the component 500 to be processed. Furthermore, this embodiment provides two symmetrically arranged cutters 230, thereby improving its chamfering efficiency. In different embodiments, the cutters 230 can be set to different shapes or different numbers according to actual usage requirements, and the present invention does not impose specific limitations on this.

[0034] See Figures 4 to 6 As shown, in this embodiment, the calibration mechanism 300 surrounds the cutter 230. The fixed seat 310 and the cutter 230 are relatively fixed in position, while the adjusting seat 320 and the cutter 230 are relatively movable. Thus, by adjusting the relative position between the fixed seat 310 and the moving seat, the exposed length of the cutter 230 can be precisely adjusted. At the same time, the support mechanism achieves hard limiting during the chamfering process, thereby ensuring the accuracy and stability of the processing.

[0035] In this embodiment, the fixed base 310 and the adjusting base 320 are connected by a threaded connection. The outer surface of the first body 312 has an external thread structure, and the inner wall of the second body 321 has an internal thread structure connected to the external thread structure. The second body 321 can rotate relative to the first body 312 to adjust the preset chamfering depth. Specifically, to facilitate rotational adjustment, both the first body 312 and the second body 321 are provided with rotating insertion holes 3213. The calibration mechanism 300 also includes two round steel wrenches, which can be inserted into the rotating insertion holes 3213 on the first body 312 and the second body 321, allowing the second body 321 to rotate relative to the first body 312. Specifically, the operator can hold the round steel wrench inserted in the first body 312 with one hand and rotate the round steel wrench inserted in the second body 321 with the other hand, thereby achieving relative rotation between the first body 312 and the second body 321. In addition, the mounting base 310 in this embodiment also includes a mounting top cover 311 and an oil seal 314. The mounting top cover 311 is fixed to the drive shaft 220 on one side and connected to the first body 312 on the other side. It is used to realize the connection between the mounting base 310 and the drive shaft 220, and at the same time provide an installation and connection platform for the pointer 313. The oil seal 314 is disposed between the first body 312 and the second body 321 to improve the sealing strength of the connection between the two.

[0036] See Figure 7 As shown, the adjustment seat 320 in this embodiment includes a calibration part 3211 and an assembly part 3212 connected to each other. The calibration part 3211 is connected to the fixed seat 310, and the plurality of scale protrusions 3214 are disposed on the outer surface of the calibration part 3211. The assembly part 3212 is detachably connected to the support assembly 322. Specifically, the spacing between adjacent scale protrusions 3214 is at the millimeter level, thereby realizing the millimeter-level control adjustment of the extension length of the cutter 230. In this embodiment, the spacing between two adjacent scale protrusions 3214 is 1.0 mm. In different embodiments, different adjustment accuracies can be achieved by replacing scale protrusions 3214 with different spacing distances.

[0037] See Figure 8 and Figure 9As shown, in this embodiment, the support component 322 is used to support the surface of the component 500 to form a hard limiting structure for the working position of the cutter 230. Specifically, it includes a connecting ring 3221, which is hollow inside and has multiple ball bearing receiving grooves at its bottom. The multiple bullseye balls 3222 are detachably disposed in the multiple ball bearing receiving grooves. In this embodiment, the multiple bullseye balls 3222 are evenly spaced at the bottom of the connecting ring 3221, which can reduce the friction intensity between them and the surface to be processed by rolling support, thereby improving the surface protection effect of the component 500 while ensuring the supporting and limiting function.

[0038] See Figure 9 As shown, based on the above structural design, the pointer 313 and the scale protrusion can fit closely together during actual use. Thus, the operator can intuitively understand the actual chamfering depth by observing the relative position between the pointer 313 and the scale protrusion, thereby enabling this floating force control calibration limit chamfering processing equipment to be applicable to more precise processing scenarios.

[0039] Example 2

[0040] This embodiment provides a floating force control calibration and limiting chamfering processing method, which uses the above-mentioned floating force control calibration and limiting chamfering processing equipment to perform floating force control calibration and limiting chamfering processing. It includes: step S1, measuring the preset chamfering processing depth required for the component 500 to be processed; step S2, adjusting the calibration mechanism 300 so that the pointer 313 points to the scale protrusion 3214 corresponding to the preset depth; step S3, moving the chamfering mechanism 200 to the component 500 to be processed, so that the multiple bullseye balls 3222 in the support component 322 abut against the surface of the component 500 to be processed, and at the same time, making the cutter 230 abut against the edge of the component 500 to be processed. At this time, the length of the cutter 230 exposed outside the support component 322 is the same as the preset depth distance; step S4, driving the cutter 230 to rotate, and at the same time, driving the cutter 230 to move along the edge of the component 500 to be processed through the moving mechanism 100 until the circumferential chamfering processing of the component 500 to be processed is completed.

[0041] In summary, the floating force-controlled calibration and limiting chamfering processing equipment and method described in this invention uses the moving mechanism 100 to drive the chamfering mechanism 200 and the calibration mechanism 300 to move synchronously. Furthermore, the precise adjustment of the chamfering depth is achieved through the cooperation between the pointer 313 and the scale protrusion 3214 in the calibration mechanism 300. Simultaneously, the support component 322 forms a hard limiting structure for a fixed chamfering depth, thereby ensuring that the cutter 230 can perform a stable chamfering process on the workpiece 500 during the chamfering process. Compared to conventional chamfering processing technologies, this application has higher adjustment accuracy and a more stable limiting structure, making it suitable for high-precision machining scenarios. In addition, it also has advantages such as high controllability, ease of operation, high product yield, and stable production process, making it a novel chamfering processing technology with broad application prospects.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
