Embodiment 2

[0037] This embodiment discloses a laser cladding machine tool, such as Figure 2-Figure 3 As shown, the workpiece clamping device for the laser cladding machine tool described in Embodiment 1 is installed, the main shaft of the laser cladding machine tool is connected to the first fixing member 7, and the tailstock is installed on the laser cladding machine tool On the tail sub-spindle 10 of the body, both the tailstock and the sub-spindle are slidingly connected with the bed, and the laser cladding machine tool also includes a three-axis moving table 9 and a laser cladding head 8 installed thereon, as well as electric control, communication Lines and peripheral equipment such as cooling, dust removal, powder feeding, and protection. The above-mentioned equipment is the terminal and body for processing, which determines the stability and safety of the processing process and the final quality of the processed workpiece. The existing structure and scheme can be used. Its specif...

Embodiment 3

[0049] This embodiment discloses a working method of the laser cladding machine tool described in Embodiment 2:

[0050] Such as Figure 4 As shown, in the processing process, the main control system of the laser cladding machine tool calculates the constant torque required by the sub-spindle in advance according to the geometric parameters and material parameters of the workpiece, and sends this torque command to the sub-spindle servo motor, and interpolates at the same time Calculate and issue the position or speed commands of the servo motors connected to other axes, and each servo motor will act according to the commands. The tailstock applies a set axial load to the workpiece through the second fixture, and the main control system periodically sends a constant torque command to the sub-spindle servo motor through the bus, and the sub-spindle servo motor responds to the command to achieve constant axial force control .

[0051] The first fixing part rotates under the dri...

Abstract

The invention relates to a workpiece clamping device, machine tool and method for laser cladding. The workpiece clamping device comprises a first fixing part and a second fixing part which can be fixed to the two ends of a workpiece, wherein the first fixing part is used for being connected with a main shaft of the machine tool; the second fixing part is rotationally connected with a tail frame; the second fixing part can apply constant pressure or tension in the axis direction of the workpiece to the workpiece according to the gravity and heat influence conditions of the workpiece; the tail frame is fixedly connected with a moving part; the moving part can be in sliding connection with a machine tool body of the machine tool; the moving part is connected with a lead screw; and the lead screw is connected with a drive part capable of outputting constant torque. By the adoption of the clamping device, machine tool and method, the technical defects and potential safety hazards caused bydeformation generated by the composite influence of gravity and heat in the workpiece cladding process can be avoided.

Description

technical field [0001] The invention relates to the technical field of processing equipment, in particular to a workpiece clamping device, machine tool and method for laser cladding. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Laser cladding technology is a material surface treatment technology that has gradually emerged in the field of laser processing in recent years. It integrates multidisciplinary content such as machinery, electronics, materials, optics, and control, and has the characteristics of high efficiency and good quality. The principle of laser cladding is to use high-power, high-density laser beams to focus on the surface of the workpiece, quickly and simultaneously melt the base material and the cladding material, and obtain high hardness, high wear resistance, corrosion resistance, and high temperature resistant modified materi...
