Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, and in particular to a chamfering device for stone processing with adjustable angle. Background Technology

[0002] Stone beveling is a crucial process in architectural decoration, tombstone carving, and other fields. Traditional beveling equipment generally suffers from the following problems: 1. Limited angle adjustment: Most equipment uses manual adjustment of the beveling angle, relying on worker experience, making it difficult to guarantee consistent precision, and unable to quickly switch between complex angles (such as beveling polyhedral irregular shapes). 2. Lack of real-time angle detection and feedback mechanisms: During processing, angle deviations are easily caused by mechanical vibration or transmission errors, requiring repeated calibration. 3. Traditional equipment is difficult to be compatible with stones of different sizes and shapes, and tool interference or processing dead angles are prone to occur when beveling curved or inclined surfaces.

[0003] To address the aforementioned issues, while existing technologies have made some automation improvements (such as electric angle adjustment), they still suffer from shortcomings such as insufficient transmission accuracy, limited detection methods, and low levels of intelligence. There is an urgent need for a solution that integrates high-precision transmission, multi-dimensional detection, and intelligent control. Utility Model Content

[0025] In the attached diagram, all identical reference numerals refer to the same components.

[0026] like Figure 1-5 As shown, this utility model provides a chamfering device for stone processing with adjustable angle, comprising:

[0027] Base 1: A rectangular frame welded from high-strength steel plates, with linear guide rail mounting grooves on the surface for fixing the three-axis moving mechanism 2.

[0028] Please see the appendix Figure 5 The three-axis moving mechanism 2 includes: an X-axis slide 21 with a stroke of 1200 mm, driven by a ball screw, equipped with a grating ruler displacement sensor 24, and a positioning accuracy of ±0.02 mm; a Y-axis slide 22 with a stroke of 1000 mm, having the same structure as the X-axis, and a Z-axis lifting stage 23 installed in the middle; and a Z-axis lifting stage 23 with a stroke of 300 mm, driven vertically by a servo motor via a ball screw.

[0029] Please see the appendix Figure 3-4 The chamfering mechanism 3 includes: a fixed base 31 fixed to the side of the Z-axis lifting platform 23 by bolts, on which the following components are mounted: the output shaft of the angle drive motor 32 is connected to the drive pulley via a keyway; and a bearing housing 33 with a built-in deep groove ball bearing supporting the transmission shaft 324.

[0030] The angle adjustment base 34 includes the following components: a drive shaft 324 supported by a bearing housing 33 and connected to the driven pulley 323 via a key. The output shaft of the chuck drive motor 35 is connected to a triangular chuck 36 via a coupling. The triangular chuck 36 is a three-jaw self-centering chuck with a clamping range of φ10-φ50mm, and a chamfering cutter 37 is fixed by a quick-release clamp 361. The chamfering cutter 37 is cylindrical in shape and has a diamond coating on its surface.

[0031] The limiting component 38 includes: a limiting boss 381 connected to the side of the angle adjusting base 34 by bolts; and an angle limiting post 382: a cylindrical hard alloy post fixed to the fixed base 31 by bolts, with its surface covered with polyurethane.

[0032] The angle detection component 39 includes: an L-shaped light-shielding plate 391 vertically fixed to the edge of the limiting boss 381; and a through-beam photoelectric sensor 392 with a resolution of 0.1°, a detection distance of 10-50mm, and a signal output to the control module 5.

[0033] Please see the appendix Figure 5 Positioner 4: Rotary worktable 41: 800mm in diameter, driven by tilt adjustment mechanism 42. Tilting adjustment mechanism 42: driven by servo motor, tilt angle range -30° to +90°, repeatability ±0.1°.

[0039] 4.

[0041] This utility model is a chamfering device for stone processing with adjustable angle. Through the combination of modular design and intelligent control technology, it achieves high precision, high efficiency and high adaptability in stone chamfering processing, and can be widely used in architectural decoration, stone carving and other fields.
