Description

Technical Field

[0001] This utility model belongs to the field of gear processing technology, and in particular relates to a tooling structure for replacing the cutter bar of a gear milling machine. Background Technology

[0002] The tool holder is a key component of the gear milling machine's spindle box, serving as the connection between the spindle box's gear transmission system and the gear milling cutter head. To adapt to different workpiece processing requirements, the gear milling machine's cutter head needs to be replaced. This replacement process necessitates the disassembly and assembly of the tool holder. Furthermore, during long-term operation of the gear milling machine, the tool holder will eventually need replacement due to wear. Because the tool holder is horizontally mounted relative to the ground and is cylindrical, it is difficult to fix on a flat surface and hoisting is challenging. Tool holder replacement often relies on manual handling. When dealing with heavy tool holders, manual support is insufficient, and with limited manpower, it is difficult to smoothly assemble and install them with the cutter head. The installation process can easily damage spindle box components, resulting in low installation efficiency and significant safety hazards. Therefore, we provide a tooling structure for replacing gear milling machine tool holders to solve the aforementioned problems. Utility Model Content

[0005] This utility model is a tooling structure for replacing the tool holder of a gear milling machine, including a base, a linear guide, a slider, a tool holder support, a fixed support, and a limiting block. The linear guide is detachably connected to the base, the slider is slidably connected to the linear guide through a structural groove, the tool holder support is detachably connected to the slider, the fixed support is detachably connected to the base, and the limiting block is detachably connected to the base.

[0006] The present invention is further configured such that the linear guide is fixed at the center line position on the upper surface of the base, the fixing bracket is fixed at one end of the upper surface of the base, and the limiting block is fixed at the T-shaped hole on the upper surface of the base.

[0007] The present invention is further configured such that the lower surface of the tool holder and the upper surface of the slider are connected by screws.

[0008] The present invention is further provided that the fixed bracket has two fixing holes on its side.

[0009] The present invention is further provided that both vertical stiffeners of the tool holder are provided with arc grooves.

[0010] This utility model has the following advantages: The detachable tool holder and fixed bracket allow for replacement according to the tool holder and spindle box model. The base has a flat bottom surface, allowing it to be placed on a lifting platform or other devices for operation.

[0019] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1

[0021] Please see Figure 1-6This utility model is a tooling structure for replacing the cutter bar of a gear milling machine, including a base 1, a linear guide 2, a slider 3, a cutter bar support 4, a fixed support 5, and a limiting block 6. The linear guide 2 is detachably connected to the base 1, the slider 3 is slidably connected to the linear guide 2 through a structural groove, the cutter bar support 4 is detachably connected to the slider 3, the fixed support 5 is detachably connected to the base 1, and the limiting block 6 is detachably connected to the base 1.

[0022] Specifically: The top surface of base 1 has a connecting hole for linear guide 2, a connecting hole for fixed bracket 5, and a T-shaped hole for limiting block 6. The other end of base 1 has an upward folded edge. A support plate is welded to the bottom surface of base 1. Lifting lugs are welded to the side of base 1. A countersunk hole is opened on the center line of linear guide 2. The connecting hole for linear guide 2 on base 1 is located on the center line of the top surface of base 1 and is a through hole. The countersunk hole of linear guide 2 is connected to the through hole of base 1 with screws and nuts. The bottom plate of tool holder 4 has a connecting hole and contains three ribs perpendicular to the bottom plate. The three ribs are of equal width and parallel to each other. Two ribs on the same side are of equal height and have the same arc groove. The height of the other rib is lower than the previous two ribs. The hole on the bottom plate of tool holder 4 is connected to the top surface of slider 3 with screws. The bottom plate of fixed bracket 5 has a connecting hole and a center groove. The side plate has an arc groove and a connecting hole perpendicular to the bottom plate. The bottom plate and the side edge of the side plate are connected by welding ribs. The limiting block 6 is L-shaped and has a through hole on the bottom surface of the L-shaped block.
