In the precision gear hobbing of PEEK gears, the use of specialized mounting fixtures is crucial for ensuring machining accuracy and stability.
[0003] Precision hobbing of PEEK gears requires a high-precision, stable mounting fixture to ensure machining quality and efficiency. Fixture design must consider factors such as material selection, machining accuracy, and thermal stability to meet the machining requirements of PEEK gears.
[0004] Traditional fixture clamping mechanisms are often not fully adaptable to the requirements of different specifications of PEEK gears, which may result in insufficient precision control of the gears during the machining process, affecting the meshing accuracy, surface quality and precision of the gears. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a mounting fixture for precision hobbing of PEEK gears, aiming to improve the problem that the gear mounting fixtures in the traditional technology cannot fully adapt to the requirements of different specifications of PEEK gears, resulting in reduced gear meshing accuracy and gear quality.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mounting fixture for precision hobbing of PEEK gears, including a worktable, a machining tool fixedly connected to the top of the worktable, a clamping mechanism provided at the bottom of the worktable, the clamping mechanism being used to fix the gear during machining, and a heat dissipation mechanism provided inside the worktable, the heat dissipation mechanism being used to cool the gear during machining.
[0007] The clamping mechanism includes a base, the bottom of which is fixedly connected to the inner bottom of the worktable. An electric push rod is rotatably connected to the inner bottom of the worktable. A connecting shaft is fixedly connected to the output end of the electric push rod. A turntable is rotatably connected to the top of the connecting shaft. Three rotating shafts are rotatably connected to the inner bottom of the worktable. A slide rod is rotatably connected to the outside of each rotating shaft. A limit sleeve is slidably connected to the outside of each slide rod.

[0010] As a further description of the above technical solution:
[0011] The limiting sleeve is slidably connected between the base and the turntable.
[0012] As a further description of the above technical solution:
[0013] The top of the base is fixedly connected to three stabilizing shafts, and the tops of the three stabilizing shafts are slidably connected to the bottom of the turntable.
[0014] As a further description of the above technical solution:
[0015] The heat dissipation mechanism includes a water tank, which is fixedly connected inside the workbench. A cool air blower is fixedly connected to the rear side of the workbench. A water pump is fixedly connected to the outside of the cool air blower. A water inlet pipe is fixedly connected to the input end of the water pump. The side of the water inlet pipe away from the water pump is fixedly connected to the outside of the water tank. A cold water pipe is fixedly connected to the output end of the water pump.

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, when clamping the gear, the electric push rod is activated to rotate the turntable through the connecting shaft, which causes the limiting shaft to drive the limiting sleeve to rotate between the base and the turntable. The rotating shaft causes the three sliding rods to rotate relative to each other, and the three clamping wheels to converge and clamp and fix the gear. This achieves the effect of clamping and fixing the gear during the installation process through the clamping mechanism. It can be applied to more specifications of PEEK gears, ensuring the meshing accuracy of the gear and improving the quality of the gear.
[0024] 2. In this utility model, during gear installation and processing, a water pump is started to draw water from inside the water tank and deliver it through a cold water pipe to the heat dissipation fins for cooling. A cooling fan draws cold air into the cooling box and then blows it onto the working surface of the gear for air cooling. The cooled water is delivered through a conveying pipe to an atomizing nozzle for water cooling of the gear. Excess water flows back into the water tank through a water tank to avoid waste. This achieves the effect of cooling the gear during the gear installation and processing through a heat dissipation mechanism, preventing the gear from deforming due to overheating and improving the gear processing accuracy.

The slide rods 8 are rotatably connected to the outside of the rotating shafts 7. The slide rods 8 are slidably connected to the outside of the slide rods 8. The limit sleeve 9 limits the movement of the slide rods 8. A clamping wheel 10 is rotatably connected to the side of the slide rod 8 away from the rotating shafts 7. The clamping wheel 10 acts as a clamp. The top of the base 3 is rotatably connected to three limiting shafts 11, which serve as limiting slide rods 8. All three limiting shafts 11 pass through the interior of the limiting sleeve 9. The tops of the three limiting shafts 11 are rotatably connected to the bottom of the turntable 6. The limiting sleeve 9 is slidably connected between the base 3 and the turntable 6. The top of the base 3 is fixedly connected to three stabilizing shafts 12, and the tops of the three stabilizing shafts 12 are slidably connected to the bottom of the turntable 6.
[0034] Specifically, the electric push rod 4 drives the connecting shaft 5 to rotate the turntable 6, causing the slide rod 8 to slide inside the limiting sleeve 9, so that the three clamping wheels 10 are relatively gathered together and the gear is fixed on the upper part of the worktable, and then the gear can be installed and processed by the machining machine 2.
[0035] Reference Figure 1 and Figure 3 - Figure 4The heat dissipation mechanism includes a water tank 13, which stores water and is fixedly connected to the inside of the workbench 1.

A water pump 16 is fixedly connected to the outside of the cool air blower 14, which pumps water. A water inlet pipe 17 is fixedly connected to the input end of the water pump 16, which delivers water. The side of the water inlet pipe 17 away from the water pump 16 is fixedly connected to the outside of the water tank 13.

[0037] Working principle: The gear is placed on the upper part of the workbench 1 and installed and processed by the machining tool 2. When clamping the gear, the electric push rod 4 is activated, which causes the turntable 6 to rotate through the connecting shaft 5. This causes the limiting shaft 11 to drive the limiting sleeve 9 to rotate between the base 3 and the turntable 6. Through the rotating shaft 7, the three sliding rods 8 rotate relative to each other, and the three clamping wheels 10 come together to clamp and fix the gear.
