Abstract
Description
Technical Field
[0001] This utility model relates to the field of bevel gear fixture technology, specifically a bevel gear tooling fixture. Background Technology
[0002] Bevel gears are suitable for mechanical equipment with complex transmissions. They can change the transmission ratio and achieve torque at different speeds, and are widely used in various industrial equipment.
[0003] The teeth of the bevel gear are located on the outer inclined surface, and the punching teeth on the inclined surface need to be positioned using special fixtures. However, after the existing bevel gear is punched into a rough blank, it is necessary to drill a hole in the middle and use bolts and other parts to fix the rough material after drilling. However, this clamping method is not conducive to adjusting the inclination angle of the top inclined surface of the rough material. In order to ensure that the top inclined surface of the rough material is compatible with the punching equipment, it is necessary to rely on other fixtures to adjust its angle. This method requires repeated disassembly and assembly of the rough material, which is not only time-consuming, but also results in errors in accuracy after each disassembly and assembly.
[0004] In view of this, a bevel gear tooling fixture was designed to solve the above problems. Utility Model Content

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0034] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0035] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a bevel gear tooling fixture. Example 1
[0036] Combination Figures 1-5 As shown, the present invention provides a bevel gear tooling fixture, including a gear blank 100, a support and rotation mechanism 200 disposed on one side of the gear blank 100, and an angle control mechanism 300 mounted on the support and rotation mechanism 200, wherein the angle control mechanism 300 is disposed on the other side of the gear blank 100. The support and rotation mechanism 200 is used to cooperate with the angle control mechanism 300 to fix the gear blank 100 on both sides and to adjust the tilt angle of the gear blank 100.
[0037] The support and rotation mechanism 200 includes a shaft 210 disposed on an external punch press and a pressure-bearing end 220 movably mounted on the shaft 210.
[0038] The end of the pressure-bearing end 220 away from the shaft 210 is adapted to fit onto the gear blank 100;
[0039] A load-bearing plate 230 is provided outside the shaft 210, a locking bolt 240 is installed at the bottom of the load-bearing plate 230, a first lever arm 250 is provided outside the locking bolt 240, and a second lever arm 290 is movably installed at the bottom end of the first lever arm 250.
[0040] An end rod is provided in the middle of the second lever arm 290;
[0041] The first lever arm 250 has a groove inside, and the base 260 is movably installed in the groove;
[0042] An adjusting nut 270 and a screw 280 are movably installed in the adjusting nut 270 on one side of the base 260.
[0043] The ring at the top of the screw 280 is movably mounted on the outside of the end rod;
[0044] The angle control mechanism 300 includes a locking assembly 380 adapted to fit the other side of the gear blank 100, a pressure boosting column 330 disposed outside the locking assembly 380, a limiting bolt 340 installed in the top threaded sleeve of the pressure boosting column 330, two pads 310 movably installed at the top of the second lever arm 290, and a pad shaft 320 installed between the two pads 310, with the pad shaft 320 movably installed in a groove inside the pressure boosting column 330;
[0045] The two feet 310 are provided with frame plates 350 on their exteriors;
[0046] The booster column 330 is adapted to penetrate into the frame plate 350;
[0047] A pad 360 and a lead screw 370 installed inside the pad 360 are mounted on the outer end of the frame plate 350.
[0048] A rotating wheel is installed at the outer end of the lead screw 370, and the inner end of the lead screw 370 is adapted to bear pressure on the end of the booster column 330.
[0049] After the shaft 210 is installed on the rotating platform of the punch press, the reinforcing nut inside the locking bolt 240 can be adjusted in sequence until the first lever arm 250 and the load-bearing plate 230 are fixed at the selected tilt angle. Then, the outer end wheel of the lead screw 370 is adjusted to rotate clockwise until the pressure column 330 is pressed and cooperates with the locking assembly 380 to fix the gear blank 100 in the center.
[0050] Next, use a wrench to adjust the adjusting nut 270 clockwise until the screw 280 is rotated and extends outward until the angle control mechanism 300 tilts the gear blank 100 along the bearing end 220 as the axis. Finally, the gear blank 100 in a fixed state can be freely adjusted for selective angle with the external punching equipment. Example 2
[0051] Combination Figures 3-5 As shown, based on Embodiment 1, the locking bolt 240 consists of a T-shaped stud and a reinforcing nut;
[0052] Anti-slip pads are installed on both end faces of the pressure-bearing end 220 and the pad 384 facing the gear blank 100;
[0053] The column head 381 has an annular groove on the guide rod that extends into the booster column 330, and the end of the limiting bolt 340 that extends into the booster column 330 is fitted and engaged in the annular groove of the guide rod.
[0054] The inside of the column head 381 is provided with a rectangular through hole, and the hexagonal end of the clamping nut 383 is located inside the rectangular through hole.
[0055] Preferably, a bearing can be installed in the horizontal hole at the top of the load-bearing plate 230, and the load-bearing plate 230 can be installed on the outside of the shaft 210 through the bearing. As the rotating platform inside the punch press drives the shaft 210 to rotate, the gear blank 100 after being pressed at the tilt angle will not have a deflection problem during rotation.
[0056] At this point, the pressure-bearing end 220 and the pad 384, which are pressurized and fixed on both sides of the gear blank 100, will not fall off during rotation. Example 3
[0057] Combination Figure 1 and Figure 5As shown, in the above embodiment, the locking assembly 380 includes a column head 381 movably mounted on one end of the pressure column 330, a spring 382 connected inside the column head 381, a clamping nut 383 movably mounted inside the column head 381, and a pad 384 installed inside the clamping nut 383.
[0058] Preferably, the spring 382 located inside the column head 381 can press the pad 384 toward the narrow face of the gear blank 100 in the initial state. After the wrench is used to rotate the clamping nut 383 through the rectangular through hole, the threaded section inside the pad 384 will be continuously pressed toward the gear blank 100 by the rotational thrust.
[0059] The working principle and usage process of this utility model are as follows: First, one end of the shaft 210 is installed on the punch press. At this time, the pressure-bearing end 220, which is movably installed on the other end of the shaft 210, can provide a pressure-bearing platform for the back of the gear blank 100. Then, the nut inside the locking bolt 240 is adjusted. After the nut inside the locking bolt 240 is loosened, the tilt angle of the control second lever arm 290 and the first lever arm 250 can be adjusted.
[0060] Next, the end of the pad 384 extending through the column head 381 is attached to the front of the gear blank 100. Then, the screw 370 is rotated clockwise. At this time, the pressure column 330 will be pressed and apply pressure to the locking assembly 380 as a whole until the second lever arm 290 and the first lever arm 250 after the tilt angle adjustment work together with the pressure column 330 and the locking assembly 380 to fix the center of both ends of the gear blank 100.
[0061] After the gear blank 100 is initially locked and fixed, the tightening nut 383 needs to be adjusted by wrench and rotated counterclockwise until the shim 384 and the pressure-bearing end 220 further fix the gear blank 100.
[0062] When it is necessary to perform tooth cutting on the inclined surface of the gear blank 100, the adjusting nut 270 can be adjusted by wrench. As the adjusting nut 270 rotates clockwise, the second lever arm 290 will drive the angle control mechanism 300 and the gear blank 100 to tilt along the bearing end 220 as the axis until the inclined surface at the top of the gear blank 100 is symmetrical with the external punching device in the horizontal direction. At this time, the gear blank 100 after the selected angle control can be easily punched quickly.
[0063] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
