Description

Technical Field

[0001] The utility model belongs to the technical field of helical gear processing, and in particular relates to a helical gear precision milling processing positioning device. Background Art

[0002] In the existing helical gear processing, when the helical gear groove is precisely polished, the position of the helical gear needs to be manually adjusted. After visually checking that the helical gear marking position is directly above the processing equipment, the broaching process is performed, which is time-consuming and labor-intensive. Among them, the "A helical gear processing positioning device" disclosed in the application number "CN.202023202293.1" is also an increasingly mature technology. The helical gear is mounted on the mold body through the positioning shaft by embedding the positioning shaft into the inner hole of the helical gear, and the axis of the positioning shaft is perpendicular to the right end face of the mold body. The helical gear is installed on the mold body through the positioning shaft. The positioning assembly is arranged on the top surface of the mold body through a mounting seat, and the end of the positioning assembly is embedded in the tooth groove of the helical gear. The positioning assembly plays a positioning role for the helical gear, preventing the helical gear from shaking during the processing and improving the processing accuracy. However, the device also has the following defects: due to jitter, the clamping point of the claw block is offset, resulting in the subsequent position of the helical gear being offset, affecting the processing accuracy of the helical gear. At the same time, the helical gear with a position offset cannot be repositioned. After the fixed end of the helical gear is loosened, the clamping force is insufficient, which easily causes the helical gear to fall off. Utility Model Content

[0003] The purpose of the utility model is to provide a helical gear precision milling positioning device, which aims to solve the problem in the prior art that due to jitter, the clamping point of the claw block is offset, resulting in the subsequent position of the helical gear being offset, affecting the helical gear processing accuracy, and at the same time, the helical gear with a position offset cannot be repositioned. After the fixed end of the helical gear is loosened, the clamping force is insufficient, which easily causes the helical gear to fall off.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: it includes a base, the four corners of the base are provided with bow-shaped movable slide grooves, a bow-shaped clamping block is slidably connected in the bow-shaped movable slide groove, movable grooves are provided on both sides of the bottom of the base, a clamping pneumatic telescopic rod is provided on one side of the inner wall of the movable groove, a movable slider is slidably connected in the movable groove, a Y-shaped push rod is provided at the bottom of the movable slider, a movable groove is provided at the bottom of the bow-shaped clamping block, both ends of the Y-shaped push rod are slidably connected in the movable groove, a gear limiting hole is provided in the middle of the base, and a gear pressure rod is threadedly connected in the gear limiting hole.

[0007] In an implementation scheme of a helical gear precision milling positioning device of the present utility model, a first air pressure control valve is provided at the bottom of one end of the clamping pneumatic telescopic rod.

[0008] In this solution, the first air pressure control valve is used to make the clamping pneumatic telescopic rod move synchronously. At the same time, the first air pressure control valve controls the output air pressure of the clamping pneumatic telescopic rod to keep the air pressure at the output end in a balanced state. The four clamping pneumatic telescopic rods are extended at the same time and the air pressure is kept consistent, so that the bevel gear is clamped at the center position of the base by the four clamping ends, avoiding the position of the bow-shaped clamping block from shifting.

[0009] In an implementation scheme of a helical gear precision milling positioning device of the present utility model, a second air pressure control valve is provided at the bottom of one end of the auxiliary pneumatic telescopic rod.

[0010] In this solution, the gear pressure rod is installed into the gear limiting hole, the top of the fixed helical gear is pressed against it, and the helical gear is clamped on the top of the base. At the same time, the auxiliary pneumatic telescopic rod extends out of the limiting clamping block and presses against the bottom of the gear pressure rod to fix the position of the gear pressure rod and prevent the gear pressure rod from shifting in the process of clamping the helical gear.

[0011] In an implementation scheme of a helical gear precision milling positioning device of the present utility model, air pressure detection gauges are provided at the bottoms of the first air pressure control valve and the second air pressure control valve.

[0012] In this solution, the air pressure values ​​controlled by the first air pressure control valve and the second air pressure control valve are detected by an air pressure detection meter, thereby improving the accuracy of the air pressure.

[0013] In an implementation scheme of a helical gear precision milling positioning device of the utility model, a non-slip clamping block is provided on one side of the top of the bow-shaped clamping block.

[0014] In this solution, when the bow-shaped clamping block clamps the side wall of the helical gear, the anti-slip clamping block presses against the side wall of the helical gear to prevent positional deviation during the clamping process of the helical gear.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1) The two ends of the Y-shaped push rod move in the moving groove on the bow-shaped clamping block, pushing the bow-shaped clamping block to move in the bow-shaped moving slide. The bow-shaped clamping block moves in the bow-shaped moving slide to clamp the helical gear on the base. The first air pressure control valve is used to make the clamping pneumatic telescopic rod move synchronously. At the same time, the first air pressure control valve controls the output air pressure of the clamping pneumatic telescopic rod to keep the output end air pressure balanced. The four clamping pneumatic telescopic rods are extended at the same time and the air pressure is kept consistent, so that the helical gear is clamped at the center of the base by the four clamping ends, avoiding the position of the bow-shaped clamping block from shifting, facilitating the repositioning of the helical gear, and slightly adjusting the position of the helical gear being processed by maintaining consistent air pressure.

[0017] 2) The auxiliary pneumatic telescopic rod extends the limit clamping block and presses against the bottom of the gear pressure rod to fix the position of the gear pressure rod, thereby preventing the gear pressure rod from positional deviation during the process of clamping the helical gear and improving the stability during the helical gear processing.
