Description

Gear shaping clamping tool for internal spline shaft

Technical Field

The utility model relates to the field of tools, in particular to an internal spline shaft gear shaping clamping tool.

Background

Wind power generation has been rapidly developed in recent years due to the advantages of no pollution, low construction cost, and the like.

In the wind power gear box, the internal spline shaft is subjected to gear shaping processing together with the gear baking. As wind power gearboxes continue to increase in reliability requirements, the spline shaft needs to be nitrided to enhance performance and wear resistance. This requires a separate gear shaping of the spline shaft.

Because a great offset force is generated during processing, a more stable tool is required to clamp the internal spline shaft so as to ensure the processing precision.

Disclosure of utility model

The utility model provides an internal spline shaft gear shaping clamping tool, which aims to solve the defects in the prior art, firmly clamp an internal spline shaft and ensure the machining precision of the internal spline shaft gear shaping.

The technical scheme adopted for solving the technical problems is as follows:

Internal spline shaft gear shaping presss from both sides tight frock, its characterized in that:

The tooling bracket is fixedly connected to the workbench through a screw;

The lower end face of the internal spline shaft is horizontally arranged on the upper end face of the fixture bracket;

More than 3 equal-height blocks are placed on the upper end face of the fixture bracket;

The lower pressing plate is pressed on the end face of the lower step of the inner spline shaft, the stud passes through the through hole of the lower pressing plate and the through hole of the equal-height block and then is screwed into the screw hole of the fixture bracket, and the nut is screwed on the stud and presses the lower pressing plate;

placing a sleeve on the upper surface of the lower pressing plate, and screwing a bolt into a screw hole formed in the upper surface of the sleeve;

two ends of the strip pressing plate are respectively pressed on the upper end face of the bolt and the upper step end face of the internal spline shaft;

after the stud passes through the through hole of the strip pressing plate, the stud is screwed into the screw hole of the lower pressing plate, and the nut is screwed on the stud and presses the strip pressing plate.

The equal-height blocks are uniformly distributed on the upper end face of the fixture bracket in circumference.

The lower pressing plate pressed on the end face of the lower step of the inner spline shaft is an annular pressing plate, and the shaft hole of the annular pressing plate is sleeved outside the inner spline shaft.

The sleeve circumference is evenly distributed on the upper surface of the annular pressing plate.

The lower end face of the strip pressing plate is flush with the upper step end face of the internal spline shaft.

The utility model has the advantages that:

According to the utility model, the two pressing plates are matched with the double-headed screw rod to be tensioned, so that the upper and lower step end surfaces of the internal spline shaft are pressed, thereby providing more stable double support for the vertical internal spline shaft, clamping the internal spline shaft on a workbench, overcoming great offset force generated during processing, and clamping the internal spline shaft to ensure the processing precision.

Drawings

The utility model will be further described with reference to the drawings and examples.
