Abstract
Claims
1. A gear clamping and positioning tool for gear hobbing machines, comprising a fixed seat (1), characterized in that: The top side of the fixed base (1) near the edge is provided with multiple fixing holes, which are arrayed around the central geometric point of the fixed base (1). A through hole is provided at the center of the top side of the fixed base (1). Multiple arc-shaped connecting plates (2) are fixedly connected to the top side of the fixed base (1), which are arrayed around the through holes. A circular receiving plate (3) is fixedly connected to the top side of the multiple arc-shaped connecting plates (2). Multiple sliding grooves (4) are provided on the top side of the circular receiving plate (3), which are arrayed around the central geometric point of the circular receiving plate (3). A sliding hole is provided at the center of the top side of the circular receiving plate (3). A clamping and positioning component (5) is provided on the circular receiving plate (3) to clamp and position the gear.
2. The gear clamping positioning tool for gear hobbing machines according to claim 1, characterized in that: The clamping and positioning assembly (5) includes a telescopic cylinder (51), which is fixedly installed at the center of the bottom side of the circular support plate (3) and is located in the middle of multiple arc-shaped connecting plates (2). The piston rod of the telescopic cylinder (51) slides in the sliding hole, and a circular drive plate (52) is fixedly connected to the piston rod end of the telescopic cylinder (51).
3. The gear clamping positioning tool for gear hobbing machines according to claim 2, characterized in that: The outer side of the circular drive plate (52) is hinged with a plurality of extrusion strips (53), the plurality of extrusion strips (53) are arrayed around the central geometric point of the circular drive plate (52), the other end of the extrusion strips (53) is hinged with a sliding strip (54), and the sliding strip (54) is slidably connected in the sliding groove (4), and the top end of the sliding strip (54) is fixedly connected with an extrusion plate (55).
4. The gear clamping positioning tool for gear hobbing machines according to claim 3, characterized in that: An extrusion block (56) is fixedly connected to the outer side of the sliding strip (54), and the extrusion block (56) is close to the top side of the circular support plate (3). A first extrusion surface is provided on the extrusion block (56). A frustum-shaped extrusion ring (57) is sleeved on the outer side of the multiple sliding strips (54). A second extrusion surface is provided on the inner side of the frustum-shaped extrusion ring (57) near the circular support plate (3).
5. The gear clamping positioning tool for gear hobbing machines according to claim 4, characterized in that: The circular drive plate (52) is driven to move vertically upward by the telescopic cylinder (51). The circular drive plate (52) squeezes multiple extrusion strips (53), while multiple sliding strips (54) slide in multiple sliding grooves (4) respectively. At the same time, multiple extrusion blocks (56) squeeze the frustum-shaped extrusion ring (57), causing the frustum-shaped extrusion ring (57) to move vertically upward.
