Description

Technical Field

[0001] This utility model relates to the field of cutting tool transportation technology, and more specifically to a gear-driven cutting tool placement and transportation vehicle. Background Technology

[0002] In the production of gears and splines, gear hobbing cutters are required. As a core piece of equipment in the industrial production of gears and splines, the machining accuracy of gear hobbing cutters directly affects key quality indicators such as tooth profile error and cumulative pitch deviation. Gear hobbing cutters are hollow in the middle, resembling a long shaft, making them bulky, inconvenient to handle, and susceptible to damage. Different gear and spline production requirements necessitate different gear hobbing cutters. Therefore, developing a dedicated transport vehicle for hollow long-shaft gear hobbing cutters has significant technological value for improving gear machining quality and reducing enterprise operating costs. Utility Model Content

[0003] This utility model provides a gear cutting tool placement and transport vehicle, which solves the problems of large size, inconvenient handling, and inability to withstand impacts of gear hobbing tools.

[0004] A gear hobbing cutter transport vehicle includes a frame with casters fixed at all four corners. A U-shaped frame is fixed to the bottom of the frame, and multiple hinged frames are fixed to the U-shaped frame. A hinge shaft is fixed to the opposite face of each pair of adjacent hinged frames. An iron cylinder for inserting a gear hobbing cutter is rotatably connected between each pair of opposite hinged shafts. An arc-shaped plate that can fit against the vertical iron cylinder is fixed to the U-shaped frame between each pair of adjacent hinged frames. A locking mechanism is provided on the U-shaped frame to cooperate with the arc-shaped plate to restrict the rotation of the iron cylinder. A portal frame for supporting the gear hobbing cutter is fixed to the upper end of the frame away from the U-shaped frame.

[0005] The locking mechanism includes a rotating rod with multiple limiting plates corresponding to the iron cylinder fixedly connected to it. Each hinge frame has a hinge seat fixedly connected to it. The rotating rod is rotatably connected to multiple hinge seats. A sliding groove is provided at the edge of the frame.

Detailed Implementation

[0018] See Figures 5 to 7 A schematic diagram of an embodiment of transporting gear hobbing tools according to the present invention is shown;

[0019] A gear cutting tool placement and transport vehicle includes a frame 101 with universal wheels 102 fixed at each of its four corners. The universal wheels 102 have a self-locking function. A U-shaped frame 201 is welded and fixed to the bottom surface of the frame 101. Multiple hinge frames 202 are welded and fixed to the U-shaped frame 201. A hinge shaft 203 is fixed to the opposite surface of each pair of adjacent hinge frames 202. An iron cylinder 204 for inserting a gear hobbing tool is rotatably connected between each pair of opposite hinge shafts 203. An arc-shaped plate 210 that can fit against the vertical iron cylinder 204 is fixed to the U-shaped frame 201 between each pair of adjacent hinge frames 202. A locking mechanism is provided on the U-shaped frame 201 to cooperate with the arc-shaped plate 210 to restrict the rotation of the iron cylinder 204. A portal frame 106 for supporting gear hobbing tools is fixed to the upper end of the frame 101 away from the U-shaped frame 201.

[0020] Multiple iron cylinders 204 can be used to hold different types of gear hobbing cutters. The iron cylinders 204 located between two hinge shafts 203 can rotate. Under normal conditions, the lower end of the gear hobbing cutter is inserted into the iron cylinder 204, and the upper end of the gear hobbing cutter rests on the gantry frame 106. The whole is stored on the transport vehicle in an inclined state. The iron cylinders 204 and the gantry frame 106 work together to support the inclined gear hobbing cutter. At this time, there is no need for a locking mechanism to limit and fix the iron cylinders 204.

[0021] When the cutting tool is to be used, the top of the tool is manually lifted, so that the tool and the iron cylinder 204 are placed vertically. At this time, one side of the iron cylinder 204 is attached to the arc plate 210, and the other side of the iron cylinder 204 needs to be fixed by a locking mechanism, thus keeping the iron cylinder 204 and the cutting tool in a vertical position. Therefore, during the process of tilting the tool to a vertical position, the locking mechanism prevents the tool from falling over, improving the safety of tool use and placement. After the tool is vertical, the transport cart is pushed and placed on the tool gripping end of the machine tool, and the machine tool automatically grips and fixes the tool for use. When the machine tool needs to change tools, the transport cart is placed directly on the tool gripping end, and then the empty machine tool places the tool directly into the iron cylinder 204. This transport cart can be operated by one person, with high production efficiency; it solves the problems of large size, inconvenient handling, and inability to be bumped when hobbing tools.

[0022] See Figures 4 to 9 The diagram shows an embodiment of the limitation of the hobbing cutter angle according to the present invention;

[0023] The locking mechanism includes a rotating rod 206, on which multiple limiting plates 208 corresponding to the iron cylinder 204 are welded and fixed. Each hinge frame 202 is welded and fixed with a hinge seat 205. The rotating rod 206 is rotatably connected to multiple hinge seats 205. A sliding groove 104 is provided at the edge of the frame 101. An iron piece 207 is fixedly connected to the end of the rotating rod 206 and slidably connected in the sliding groove 104. A triangular locking block 105 for limiting the iron piece 207 is welded and fixed on one inner wall of the sliding groove 104. The iron piece 207 is located in the groove formed between the locking block 105 and the inner wall of the sliding groove 104.

[0024] When one side of the vertical iron cylinder 204 is attached to the arc plate 210 and the limiting piece 208 abuts against the other side of the iron cylinder 204, the iron piece 207 is restricted in the slot by the locking block 105. The iron piece 207 cannot rotate, and the limiting piece 208 on the rotating rod 206 will not rotate either. Therefore, the limiting piece 208 and the arc plate 210 work together to limit the vertical iron cylinder 204, so that the tool inserted in the iron cylinder 204 is also locked in the vertical position.

[0025] When it is necessary to release the locked state of the iron cylinder 204, the material of the iron plate 207 gives it a certain degree of toughness. When the iron plate 207 is pushed towards the principle block 105, the iron plate 207 disengages from the slot and slides out from the space between the block 105 and the side wall of the slide groove 104, which can drive the rotating rod 206 to rotate. The rotating rod 206 can then drive multiple limiting plates 208 to rotate away from the iron cylinder 204, thus no longer limiting the iron cylinder 204. At this time, the iron cylinder 204 is no longer locked in a vertical state, and the knife inserted in the iron cylinder 204 can lean against the gantry frame 106 at an angle.

[0026] When it is necessary to lock the vertical iron cylinder 204 again, push the iron piece 207 towards the direction of the locking block 105 again. The iron piece 207 will bend along the inclined surface of the locking block 105 and then be inserted into the slot. The locking block 105 limits the iron piece 207, thereby locking the vertical state of the tool.

[0027] Furthermore: the bottom surface of the iron cylinder 204 is hollowed out; a tray 103 is fixedly connected to the bottom surface of the frame 101. The lubricating oil of the cutting tool will flow downward under the action of gravity and be collected in the tray 103. The tray 103 contains the cutting tool lubricating oil, which can not only collect the lubricating oil on the cutting tool, but also facilitate manual replacement of the cutting tool, thus serving as a function of lubrication and maintenance of the cutting tool.

[0028] The tray 103 is tilted downwards toward the iron cylinder 204, causing the lubricating oil to accumulate on one side, making it easier to lubricate and change the cutting tools.

[0029] A handle 209 is fixedly connected to the upper end of the iron plate 207. This extends the lever arm of operating the iron plate 207, making operation easier.

[0030] A slotted frame 107 is fixedly connected to the gantry frame 106. The groove on the slotted frame 107 for placing the tool further limits the tool's position, preventing the tilted tool from swinging and improving the stability of the tool placement.

[0031] The slot frame 107 is made of wood. Wood is relatively soft, which can reduce direct collisions between the knife and hard surfaces such as metal and plastic, prevent the blade from becoming dull or chipped due to impacts, and also prevent the knife from rusting.

[0032] A handle 108 is fixedly connected to the gantry frame 106. This allows the tool to be moved to the vicinity of the machine tool by pushing the frame 101 through the handle 108.

[0033] A column 109 for auxiliary support of the grip 108 is fixed between the grip 108 and the frame 101, which increases the stability of the grip 108.
