Description

Technical Field

[0001] The utility model belongs to the technical field of grinding machines, and in particular relates to a five-axis flat hob grinder. Background Art

[0002] Hobs are gear cutting tools with teeth arranged in a spiral pattern along a cylinder or cone. They are used to generate cylindrical gears, worm gears, and other cylindrical toothed workpieces. Hobs are categorized by application, including gear hobs, worm gear hobs, non-involute generating hobs, and fixed hobs. Hobs are commonly used for machining external spur and helical cylindrical gears. Hob production typically requires the use of a hob blade grinder. The hob blade grinder is mainly used for manufacturing or grinding the cutting surface of the gear hob. It is a machine tool that uses a grinding tool to grind the surface of the workpiece. The hob blade grinder body has a base on the top wall, a hydraulic pump, a driving gear connected to the drive shaft of the hydraulic pump, a transmission shaft arranged under the base, a hydraulic oil tank arranged under the base and on one side of the transmission shaft, and a driven gear arranged on the transmission shaft. The driving gear and the driven gear are connected by a chain. The base is respectively provided with a first adjustment component and a second adjustment component for adjusting the movement of the hydraulic pump. However, when the grinder is driven by the hydraulic pump as the power source, insufficient oil pressure is likely to occur in cold winter weather, which leads to unstable power of the grinder and a defect that it is difficult to control the grinding accuracy of the grinder.

[0003] To this end, a hob blade grinder with the announcement number "CN116135455A" includes an operating table, a reciprocating device and a grinding device, the reciprocating device includes a supporting plate, a power mechanism, a driving seat and a tailstock of a machine tool, the supporting plate is slidably connected to the operating table, the power mechanism is connected to the operating table, the power mechanism is connected to the supporting plate to drive the supporting plate to slide back and forth, the driving seat is fixedly connected to the supporting plate, a tightening rod is rotatably connected to the driving seat, a reduction motor is installed on the driving seat, the reduction motor is transmission-connected to the tightening rod, and the tailstock of the machine tool is fixedly connected to the supporting plate; the grinding device is connected to the operating table, and the grinding device is used to grind the hob, which has the effect of reducing the possibility of affecting the stability of the power output of the grinder due to temperature changes, and facilitating the control of the grinding accuracy of the hob.

[0004] However, for the above-mentioned roller cutter grinder, although the staff can drive the lifting plate to rise and fall by rotating one end of the screw and turning the screw to adjust the height of the third motor and the first grinding wheel, thereby improving the convenience of adjusting the height of the first grinding wheel, the following more obvious defects still exist during use: However, during the process of grinding the flat roller cutter, the first grinding wheel cannot perform the grinding operation due to the different angular curvatures of the blade surface of the flat roller cutter, and thus the first grinding wheel cannot be adjusted and ground according to the different angles of the flat roller cutter.

Tool holders 3 for clamping and supporting the tool are provided on both sides of the end of the Z-axis transverse slide 2. The tool holder 3 can clamp and rotate the flat rolling tool 10 to be ground. A tool drive seat 4 for transmitting the clamped tool is provided on one side of the tool holder 3 and located at one end of the Z-axis transverse slide 2, driving the clamped flat rolling tool 10 to rotate for grinding operation;

[0020] The X-axis longitudinal slide 5 is slidably arranged at the center position of the rear side of the bed 1, and the grinding wheel 16 can be reciprocated back and forth to adjust the grinding depth of the grinding wheel 16. The upper end of the X-axis longitudinal slide 5 is provided with a servo rotating motor 6 for angle rotation adjustment through a vertical plate. The servo rotating motor 6 is intermittently rotated and started and stopped by an external PLC control, which is conducive to adjusting the angle of the grinding wheel 16. A Y-axis vertical slide 7 is vertically slid on the rotating shaft of the servo rotating motor 6, so that the grinding wheel 16 can be adjusted vertically in height according to the area and angle required to be ground by the flat rolling tool 10 to adapt to the adjustment of the grinding of the flat rolling tool 10 and avoid the phenomenon of damage to the flat rolling tool 10 caused by excessive grinding. The front end of the Y-axis vertical slide 7 is installed with a servo grinding motor 8 for tool grinding. The servo grinding motor 8 drives the flat grinding wheel 16 to rotate and grind the flat rolling tool 10.

[0021] The tool holder 3 is provided with a flat rolling tool 10, and the end of the tool holder 3 is provided with a clamping bearing tool seat 11 for clamping and rotating the rotating shafts at both ends of the flat rolling tool 10, so that the flat rolling tool 10 is clamped and rotated by the clamping bearing tool seat 11. A servo motor 12 is fixed through the tool driving seat 4 to drive the rotation of the clamping bearing tool seat 11, and one end of the rotating shaft of the servo motor 12 is connected to the clamping bearing tool seat 11 at one end of the Z-axis horizontal slide 2 through a connected coupling to realize the rotation grinding of the flat rolling tool 10.

[0022] An A-axis vertical plate 13 is provided at the end of the X-axis longitudinal slide 5, so that the servo rotary motor 6 is fixed on the A-axis vertical plate 13 to enhance its stability and firmness. The servo rotary motor 6 is fixed through the center position of one side of the A-axis vertical plate 13, and can realize the rotation adjustment of the grinding angle of the grinding wheel 16.
