Problems solved by technology

[0004] 1. High design and procurement costs and long lead times;
[0005] 2. It is inconvenient to use and maintain. The addition of a special chuck and its driving cylinder on the rotating spindle makes the structure of the entire spindle complex and increases the difficulty of later maintenance and repair. On the other hand, because quenching water will be sprayed during quenching, During the heating process, impurities such as scale will also be produced, which will cause corrosion and jamming on the surface and inside of the chuck, which will seriously shorten the service life of the chuck and increase maintenance costs;
[0006] 3. The types of processing parts are limited, and the structure of the special chuck is single, which cannot meet the diverse processing needs

Embodiment Construction

[0024] combine figure 1 As shown, a quenching and pressing positioning tool for the inner hole of shaft parts includes a spindle rotation assembly 1, a part positioning assembly 2, a rotating clamping assembly 5, a quenching coil and a spray device 4, a pressing arm and an auxiliary positioning assembly 6,

[0025] The tooling adopts a vertical structure, the axis of the parts is vertical, and it is installed on the work table of the machine tool as a whole. The lower part of the table is the spindle drive motor, which provides the rotating power of the parts;

[0026] The main shaft rotation assembly 1 meshes with the drive motor gear of the machine table to provide rotational power;

[0027] Part positioning assembly 2 is installed on the main shaft, on which adjustable axial positioning and radial positioning elements are installed. The positioning element makes the parts to be processed have the only correct position on the positioning pallet;

[0028] The quenching coil...

Abstract

The invention provides a shaft part inner hole quenching and pressing tool. The tool comprises a main shaft rotating assembly, a part positioning assembly, a rotary clamping assembly, a quenching coil, a spraying device, a pressing arm and an auxiliary positioning assembly. The positioning tool has the advantages that reliable pressing force and positioning precision can be provided, so that the whole machining precision is controllable, the process stability and reliability of shaft inner hole quenching machining are effectively guaranteed, and the machining quality and the production efficiency are improved.

Description

technical field [0001] The invention relates to a quenching and pressing positioning tool for the inner hole of shaft parts, which is suitable for positioning and clamping of shaft and disk parts such as the outer ring of a hub bearing when the inner holes are quenched and tempered. Background technique [0002] When using induction hardening heating technology, the quenching coil needs to extend into the inner hole of the part. If the conventional axis reference method is used to tighten and fix the parts, the induced current in the quenching coil will generate a radial force on the parts in the coil during processing, forcing the parts to deviate from the positioning axis and affecting the uniformity of the quenching process And consistency, increase the defects of shaft inner hole quenching processing, there are quality and safety risks. [0003] In response to the above problems, domestic and foreign equipment manufacturers use a rotary cylinder to push a special chuck ...
