TECHNICAL FIELD

[0001] The application relates to the technical field of grinding machining center, in particular to a multi-angle grinding precision gantry guide rail grinding machine. BACKGROUND

[0002] In the field of modern mechanical manufacturing, the precision machining of metal workpieces has become a core link. High-end manufacturing industries represented by aerospace, automobile manufacturing and mold machining have put forward strict requirements for workpiece surface precision and complex angle machining. Traditional single-function grinding and cutting equipment has low processing efficiency and large floor area due to independent function and scattered equipment. For example, the cylinder cover plane and side inclined angle of an automobile engine cylinder body need to be machined on a flat grinding device and an inclined grinding device respectively, which not only requires frequent equipment replacement, but also introduces positioning errors due to multiple clamping, affecting the precision of the workpiece.

[0003] Although early gantry machining centers have multi-axis linkage capability, most of the equipment can only realize single function of flat grinding or inclined grinding. The inclined surface machining demand cannot be met, and special inclined grinding equipment needs to be matched, resulting in increased production line equipment investment cost. At the same time, the traditional inclined grinding structure mostly adopts fixed-angle grinding wheel set, and the inclination angle of the grinding wheel is adjusted by a mechanical yoke, so the adjustment precision is low and it is difficult to meet the high-precision inclined angle machining requirement of the workpiece. Moreover, the polishing depth adjustment relies on manual screw rod, which cannot meet the depth control requirement in precision mold machining.

[0004] In addition, the convenience in maintenance is poor. The driving structure is integrated with the main frame, such as the main shaft driving group is fixed on the gantry stand, and the whole frame structure needs to be disassembled during maintenance, which takes a long time for single maintenance and seriously affects the production efficiency.

The limiting clamping plates 804 are fixedly installed at both ends of the moving seat plate 803 to clamp the rotating roller part 81, thereby driving the polishing assembly 8 to telescope, accurately controlling the polishing depth and improving the processing precision and efficiency.

[0038] Referring to Figure 6 and Figure 12As shown, the main shaft driving group 9 includes an angle grinder main shaft motor 91, a transmission rod 92 and a plug-in plate 93. The angle grinder main shaft motor 91 is fixedly installed on the upper end face of the main frame shell 71. One end of the transmission rod 92 is connected to the output end of the angle grinder main shaft motor 91. The plug-in plate 93 is fixedly installed on the other end of the transmission rod 92. A limiting sliding groove 811 is formed at the center of the upper end of the rotating roller part 81 for plug-in installation of the transmission rod 92 and the plug-in plate 93. The structure design of the angle grinder main shaft motor 91, the transmission rod 92 and the plug-in plate 93 of the main shaft driving group 9 provides rotating power for the polishing assembly 8. The angle grinder main shaft motor 91 is plug-in matched with the limiting sliding groove 811 of the rotating roller part 81 through the transmission rod 92 and the plug-in plate 93, and power is transmitted to the rotating roller part 81 to drive the polishing assembly 8 to rotate. This connection mode can ensure the stability and reliability of power transmission, and is also convenient for installation and disassembly, and facilitates maintenance and repair of the equipment.

[0039] Working principle: The multi-angle grinding and cutting gantry machining center includes the following steps when actually used.

[0040] Overall architecture and basic movement: The gantry 2 is composed of two groups of gantry uprights 21 and cross beams 22 to form a stable frame, which is vertically arranged above the machine tool 1 to provide stable support for the moving beam 3. The machine tool 1 adopts the structure of the bed 11 matched with the foot supports 12, which are evenly distributed on both sides of the lower end face of the bed 11 to disperse the weight of the machine tool 1 and enhance stability. The liquid static pressure guide rail 111 on the bed 11 supports the workbench 13 to slide, ensuring smooth operation of the workbench 13 with high precision and low friction characteristics, laying a precision foundation for workpiece machining. The moving beam 3 is driven to rise and fall by the two groups of servo motors 20 through worm gears, which can accurately position the height to meet the machining needs of different workpieces. At the same time, the first movable seat 31 and the second movable seat 32 independently rise and fall on both sides of the front end face of the moving beam 3, respectively driving the flat grinding wheel set 4 and the inclined grinding wheel set 5 to flexibly adjust the height, realizing the integration of flat grinding and inclined grinding functions, and improving the processing flexibility and efficiency.

[0041] During flat grinding, the flat grinding wheel set 4 is fixed to the front end face of the first movable seat 31 and is driven to rotate by the flat grinding main shaft motor 30 to provide power for flat grinding, ensuring the accuracy and quality of flat grinding.

[0042] When the inclined grinding is performed, the rotatable seat group 6 of the inclined grinding wheel set 5 is fixed at the front end of the second movable seat 32, and the integrated shell 7 is rotatably installed on the connecting disc seat 61 of the rotatable seat group 6 through the connecting shaft 62. The motor 601 in the driving assembly 1 drives the driving worm 602 to rotate, the driving worm wheel 603 cooperates with the driving worm 602, and the integrated shell 7 is driven to rotate around the connecting shaft 62, so that the inclined grinding angle is accurately adjusted. The polishing assembly 8 is slidingly installed at the lower end of the integrated shell 7, the motor 801 in the driving assembly 2 drives the driving screw 802 to rotate, the rotation is converted into linear motion through the cooperation of the threaded sleeve 805 and the moving seat plate 803, the moving seat plate 803 slides along the guide rail 723, and the polishing assembly 8 clamped by the limiting clamp plate 804 is extended and retracted, so that the polishing depth is adjusted. The angle grinding spindle motor 91 of the spindle driving assembly 9 is connected with the limiting sliding groove 811 of the rotating roller part 81 through the transmission rod 92 and the plug-in plate 93, and the power is transmitted to the polishing assembly 8, so that the polishing disc 84 is driven to rotate, and the inclined grinding is completed. In addition, the stability shaft seat 73 slides at the lower end of the main frame shell 71, the side wing plate 732 cooperates with the concave clamp seat 712, supports the polishing rod 83 during polishing, reduces vibration, ensures polishing accuracy and stability, and can be extended and retracted synchronously with the polishing assembly 8 to adapt to different polishing depth requirements.

For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
