Problems solved by technology

And existing grinder machine is to use diamond pen to grind and handle the flatness of its surface to restore the flatness of its surface mostly after unloading the superhard emery wheel, promptly carry out material reduction and repair on the basis of emery wheel wearing and tearing, in certain The use efficiency of the grinding wheel is reduced to a certain extent, the number of replacements of the grinding wheel is increased, and the overall resources of the society are wasted; and in the repair process, the adjustment of the grinding wheel is poor, and it is impossible to perform repair actions on all sides of the grinding wheel. Change the position of the grinding wheel according to the position to be repaired and then fix it again, the process is more cumbersome
In addition, the existing equipment cannot realize the integration of manufacturing and dressing of the grinding wheel, even for the three situations of dressing: the outer circle is not round, it needs to be rounded; the surface of the grinding wheel is passivated after grinding, and this layer of abrasives Remove; the grinding wheel itself is not passivated, but because the ground material is blocked on the surface of the grinding wheel, it cannot continue grinding; multiple installations and multi-step operations are required, and the operation process is relatively complicated, and the processing complexity is high. low efficiency

Embodiment 1

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Unless otherwise specified, the instruments or materials used in the present invention are commercially available. The application scenarios of the present invention are: manufacturing grinding wheels, grinding wheel dressing, laser sharpening and laser dressing.

[0047] Manufacture of grinding wheels: Additive manufacturing of grinding wheels and simultaneous laser sharpening and laser dressing.

[0048] Grinding wheel dressing: directly carry out laser sharpening and shaping on the worn grinding wheel, or first partially add material to repair, and then laser sharpening and shaping can be carried out simultaneously.

[0049] Laser sharpening uses the optical system to focus the laser beam into a very small spot, and acts on the surface of the grinding wheel, which can melt and vaporize the bonding material on the local surface of th...

Embodiment 2

[0087] like Figures 5 to 6 As shown, the synchronous processing device for adding and subtracting materials in this embodiment is roughly the same as that in Embodiment 1, except that:

[0088] 1. The number of gantry beams 42 is two. The laser material addition module 7 and the laser material subtraction module 8 are respectively installed on the two gantry beams 42 and are driven by different horizontal driving devices 17 to move in the horizontal direction.

[0089] The movement of the X-axis (along the length direction of the first horizontal ball screw 173 ) and the Z-axis of the laser material addition module 7 and the laser material reduction module 8 are independent of each other, realizing more complex processing.

[0090] 2. Two sets of vertical driving devices 18 are installed inside the upper part of each gantry column 41 , and the two sets of vertical driving devices 18 are respectively used to drive two gantry beams 42 . The gantry column 41 is provided with in...

Abstract

The invention discloses a material increasing and decreasing synchronous machining device capable of rapidly manufacturing or trimming a grinding wheel, which comprises a fixed base, a portal frame, a laser material increasing module, a laser material decreasing module and a workbench, the portal frame and the workbench are positioned on the fixed base, and the portal frame comprises portal frame upright posts and a portal frame cross beam; the laser material adding module and the laser material reducing module are located on a cross beam of the portal frame and conduct material adding machining and material reducing machining on a grinding wheel to be processed respectively, the small stand columns are located on the workbench, the grinding wheel spindle is horizontally arranged, and the small stand columns are arranged at the two ends of the grinding wheel spindle. The grinding wheel spindle rotates to drive a to-be-processed grinding wheel. The method has the advantages of high machining precision and long service life of the treated grinding wheel.

Description

technical field [0001] The invention relates to the field of desktop laser processing equipment, in particular to a method and device for synchronous processing of adding and subtracting materials that can rapidly manufacture or dress grinding wheels. Background technique [0002] With the rapid development of my country's manufacturing industry, the demand for customization of new mechanical equipment is increasing day by day, and the structural integration and complexity of various parts and components are constantly increasing. At the same time, high-precision, high-efficiency , low cost, low energy consumption and integration and integration requirements. This provides a broad development platform for additive / subtractive composite manufacturing technology. [0003] In order to further improve the processing accuracy and surface processing quality of the parts, the laser subtractive processing link needs to be set in the subtractive module of the additive / subtractive com...
