Technical Field

[0001] The invention relates to the technical field of propellers, and more particularly to a measuring tool for measuring the height of a propeller shell cuff. Background Art

[0002] The propeller shell is an important part of the propeller. It is used to fix all the propeller components and install the propeller on the engine shaft. It bears and transmits all the loads of the propeller. The design and quality of the propeller shell directly affect the overall performance of the propeller. Therefore, when designing the propeller shell, there are certain requirements for the error between the end faces of each propeller sleeve. However, there is currently no measuring tool for measuring the error of the propeller shaft end face.

[0003] Therefore, developing a measuring tool for measuring the height of the paddle shell cuff that is convenient and easy to operate is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0004] In view of this, the present invention provides a measuring tool for measuring the height of the cuff of a paddle shell which is convenient to measure and easy to operate.

[0009] The measuring meter is connected to the base, and the measuring contact of the measuring meter extends into the base and is located above the flat contact. The up and down movement of the flat contact will drive the measuring contact to move up and down.

[0010] The beneficial effect of adopting the above technical solution is that the ball contact of the measuring lever in the present invention contacts the end face of the paddle sleeve, the measuring lever is rotatably connected to the base, and the flat contact of the measuring lever drives the measuring contact to move up and down. By reading the value of the measuring meter, the value of the measuring meter is the distance that the flat contact moves upward, and then the height of the paddle sleeve end face can be calculated. The measurement is convenient and easy to operate.

[0011] Preferably, a measuring groove is provided inside the base, and the measuring lever is placed in the measuring groove and is rotatably connected to the inner wall of the measuring groove. The provision of the measuring groove makes the rotation process of the measuring lever more stable.

[0012] Preferably, a measuring channel is provided at the connection between the base and the measuring meter, the measuring contact is placed in the measuring channel, and the flat contact is placed below the measuring channel.

[0013] Preferably, a spring is provided between the flat contact and the measuring contact. The provision of the spring enables the flat contact to return to its original position after the measurement is completed.

[0014] Preferably, the measuring meter is connected with a bushing, which is placed in the measuring channel and sleeved on the outside of the flat contact.

[0015] Preferably, a first screw is disposed on the side of the base, and the first screw is passed through the measuring channel and tightens the bushing. The first screw can lock the bushing.

[0016] Preferably, a baffle is connected to the bottom of the base, and the baffle is located below the flat contact. The baffle can limit the position of the flat contact.

[0017] Preferably, a pad is provided at the bottom of the base, and the base and the pad are fixed by a second screw. The pad is used to ensure that the height of the measuring tool can meet the height of the end face of the paddle sleeve.

[0018] It can be seen from the above technical solutions that, compared with the prior art, the present invention discloses a measuring tool for measuring the height of the paddle shell cuff, which has the following beneficial effects:

[0019] (1) In the present invention, the ball contact of the measuring lever contacts the end face of the paddle sleeve, the measuring lever is rotatably connected to the base, and the flat contact of the measuring lever drives the measuring contact to move up and down. By reading the value of the measuring meter, the value of the measuring meter is the distance that the flat contact moves upward, and then the height of the paddle sleeve end face is calculated, which is convenient for measurement and easy to operate;

[0020] (2) The spring can reset the flat contact to facilitate the next measurement. BRIEF DESCRIPTION OF THE DRAWINGS
