Abstract

The utility model relates to a frock of interference bush is inlayed to work piece excircle heat in the machine-building process reduces the heat and inlays the unable risk of installing in place of bush in-process to improve production efficiency by a wide margin, promote product quality's slender axles and inlay set frock, both sides board and adjustable ring are connected through many double-end screw, and the adjustable ring is connected with the frock connecting plate. The advantages are that: firstly, the requirement that other equipment needs to assist in positioning and moving before traditional sleeve embedding is replaced by applying the tool, the tool can be directly applied to realize the positioning function of the sleeve in the process, so that the sleeve embedding process is more centralized, and the production efficiency is greatly improved; secondly, the situation of sleeve inserting error of the workpiece is reduced after the tool is applied, and the product quality is improved; thirdly, the tool is simple and convenient to use, the requirement of the skill level of operators is lowered, and the labor intensity of operators is reduced.

Description

Slender shaft bushing tool

Technical Field

The utility model relates to a frock of interference bush is inlayed to heat to work piece excircle in the machine-building process reduces the unable risk of installing in place of heat inlay bush in-process to improve production efficiency by a wide margin, promote product quality's slender axles and inlay a cover frock, belong to the machining and make field.

Background

In many fields such as maritime work, ship berth and the like, an interference fit bushing with the length of several hundred meters is often required to be hot-embedded on a long shaft, and the hot-embedding process has great difficulty and risk due to the fact that the shaft is easy to bend due to poor rigidity, the weight of the bushing is too heavy, the gap is too small after heating, the correction and the adjustment cannot be accurate and the like. In the traditional processing, gas heating modes such as an acetylene gun are generally adopted, and then the bushing is moved by manual positioning through a crane auxiliary hoisting bushing. Although the method can reduce the time for early preparation and other tools through the assistance of driving, the accidents of rapid cooling and blocking caused by the fact that the bushings are not mounted to the specified shaft positions when being hot-inlaid frequently occur due to the fact that the personnel in the bushing inlaying process are not coordinated, the correction and the adjustment are not accurate enough and the bushing heating cannot be uniform and continuous, and huge economic loss and product delivery delay are caused.

Disclosure of Invention

The design purpose is as follows: the defects in the background art are avoided, and the slender shaft bushing tool capable of stably and continuously heating and accurately controlling the bushing position in the bushing process is designed, so that the production efficiency is greatly improved, and the product quality is improved.

The design scheme is as follows: in order to achieve the above design objectives. The utility model adopts the technical proposal that the machine tool knife rest drives the bush to move, and ensures that two tops of the workpiece are positioned at the turning center of the machine tool. And a bolt adjusting mode is adopted between the other part of the tool hoop and the bushing, so that the bushing can be adjusted at any time in the heating process. The tool is suitable for bushings of shafts with various outer diameters and lengths.

The technical scheme is as follows: a slender shaft bushing tool is characterized in that two side plates and an adjusting ring are connected through a plurality of double-end screws, and the top of the adjusting ring is provided with a lifting ring assembly.

Compared with the prior art, the utility model has the advantages that firstly, the fixture is used to replace the requirement of other devices for auxiliary positioning and movement before the traditional sleeve embedding, and the fixture can be directly used to realize the positioning function of the sleeve in the process, so that the sleeve embedding process is more centralized, and the production efficiency is greatly improved; secondly, the situation of sleeve inserting error of the workpiece is reduced after the tool is applied, and the product quality is improved; thirdly, the tool is simple and convenient to use, the requirement of the skill level of operators is lowered, and the labor intensity of operators is reduced.

Drawings

Fig. 1 is a schematic structural view of an elongated shaft sleeve fitting tool.

Detailed Description

Example 1: reference is made to figure 1. A slender shaft bushing tool is characterized in that two side plates 1 and an adjusting ring 3 are connected through a plurality of double-end screws, and a lifting ring assembly 4 is arranged at the top of the adjusting ring 3. The adjusting ring 3 is provided with an adjusting screw 2, and the adjusting ring 3 adjusts the height and the center of the bushing through the adjusting screw 2. When the tool is used, the tool platform is connected with a screw rod of a tool rest component of a machine tool, and meanwhile, the tool adjusting ring 3 is tightly pressed through three key groove positioning pressing plates on the platform, so that the positioning and driving effects on the bushing tool are realized. In the implementation process, the requirements of bushing accuracy and safety are met, and in the bushing heating process, the bolt (adjusting screw) 2 on the adjusting ring 3 is continuously adjusted according to the heating expansion change of the bushing to enable the bushing and the slender shaft to be concentric.

In order to achieve the purpose of adjusting the position of the sleeve at any time in the sleeve embedding process, two M24 threaded holes are formed in the bottom of the adjusting ring 3, and a lengthened M24 bolt is installed to adjust the height and the front and back of the sleeve. In order to facilitate the installation and the disassembly of the tool, a hoisting hole and a hoisting ring component (tool connecting plate) 4 are arranged at the top of the tool adjusting ring 3.

It is to be understood that: although above-mentioned embodiment is right the utility model discloses a design has done more detailed word description, but these word descriptions, are only right the utility model relates to a simple word description of idea, rather than right the utility model relates to a restriction of idea, any do not surpass the utility model relates to a combination, increase or the modification of idea all fall into the utility model discloses a within the protection scope.
