Description

Technical Field

[0001] This utility model relates to the field of water turbine installation technology, specifically a rotating column sleeve for a tooling fixture for installing a water turbine. Background Technology

[0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy. It belongs to the category of turbine machinery in fluid machinery. When installing a water turbine, it needs to be installed and fixed using tooling fixtures. The rotating sleeve is a protective structure for the rotating part of the tooling fixture.

[0003] For example, Chinese patent CN217291449U discloses a rotatable clamping fixture for batch processing of plunger sleeve workpieces, which solves the problem of low processing efficiency caused by clamping plunger sleeves one by one in the prior art. A rotatable clamping fixture for batch processing of plunger sleeve workpieces includes a bridge plate. Two clamping plates are fixedly connected to the top of the bridge plate. Several pressure plates with an L-shaped structure are fixedly connected to the top of the clamping plates. Limiting blocks are provided directly below the pressure plates. A movable block is fixedly connected to the bottom of each limiting block. Slide grooves corresponding to the movable blocks are formed inside the clamping plates. The movable blocks are elastically slidably connected to the clamping plates via springs, with the springs located within the slide grooves. Two symmetrically distributed side plates are fixedly connected to the outer side of the bridge plate, and support shaft seats are installed on the outer sides of the two side plates. This utility model, through the cooperation of armor plates, multiple pressure plates and limiting blocks, can achieve the effect of batch clamping plunger sleeves, effectively improving processing efficiency. Traditional rotating plunger sleeves protect the rotating structure of the tooling, but the connection between the rotating structure and the rotating plunger sleeve is prone to wear due to long-term rotational friction, which can easily lead to gaps at the connection and reduce the protective effect on the rotating structure. Therefore, a rotating plunger sleeve for tooling fixtures for installing water turbines is proposed to solve the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 The present invention provides the following technical solution: a rotating column sleeve for a tooling fixture for installing a water turbine, comprising a sleeve 1, wherein an upper seat 3 is provided at the bottom end of the sleeve 1, and an interface 32 is provided on the outer surface of the center of the upper seat 3;

[0023] In this embodiment, a collar 33 is embedded in the bottom of the interface 32 and is rotatably connected to the inner wall of the interface 32. The outer surface of the collar 33 is provided with a groove and a plurality of balls 34 are provided inside the groove. During rotation, the collar 33 drives the inner wall balls 34 to roll, reducing wear on the interface 32.

[0024] The interface 32 has a three-step structure, which increases the sealing of the upper seat 3 connection and prevents impurities from entering the sleeve 1.

[0025] In this embodiment, the base 2 is set at the bottom end of the sleeve 1. Reinforcing blocks 11 are welded to both the upper and lower ends of the sleeve 1. The reinforcing blocks 11 at the upper and lower ends are fixedly connected to the outer surfaces of the upper seat 3 and the base 2, respectively. Fixing grooves 35 are opened on the outer surfaces of the upper seat 3, the base 2 and the reinforcing blocks 11. Reinforcing blocks 11 are installed on both ends to increase the support strength of the base 2 and the upper seat 3.

[0026] The upper seat 3 and the base 2 are fixedly installed with a connecting pipe 31 at one end. The two ends of the sleeve 1 are provided with connecting grooves 12 that match the connecting pipe 31. The upper seat 3 and the base 2 are connected by inserting the connecting pipe 31 into the connecting grooves 12 at the upper and lower ends of the sleeve 1. Then, they are connected to the reinforcing block 11 by bolts or welding, which facilitates the installation of the upper seat 3 and the base 2.

[0027] The working principle of this embodiment is as follows:

[0028] The sleeve 1 is supported by base 2 and upper seat 3 installed at both ends. At the same time, reinforcing blocks 11 are installed on both sides of both ends to increase the support strength of base 2 and upper seat 3. The interface 32 inside the upper seat adopts a three-step structure, which increases the sealing of the connection of upper seat 3 and prevents impurities from entering the sleeve 1. A collar 33 is installed on the inner wall of the interface 32. During rotation, the collar 33 drives the inner wall ball 34 to roll, reducing the wear on the interface 32.

[0029] The upper seat 3 and the base 2 are connected by inserting the connecting pipe 31 into the connecting groove 12 at both ends of the sleeve 1, and then connected to the reinforcing block 11 by bolts or welding, which facilitates the installation of the upper seat 3 and the base 2.
