Problems solved by technology

The existing intermediate frequency quenching machine tools use bent steel plates as columns, and the rigidity of the machine tool is poor; the cylindrical optical axis is used as the guide rail, which has poor rigidity and is easy to deform; these two reasons lead to obvious vibration of the workpiece during work, which affects the quenching accuracy; The motor that rotates the workpiece is under the workpiece, so it is not easy to be waterproof and easily affected by moisture, and the motor is often burned out; the lower end of the screw is not equipped with a thrust ball bearing, resulting in frequent damage to the deep groove ball bearing and the screw pair

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Such as Figure 1-Figure 5 As shown in the figure, the motor-driven intermediate frequency quenching machine tool fixes the base 1 on the ground and adjusts the level by 0.06mm / 1000mm.

[0026] Install the guide rail Ⅲ93 and the guide rail Ⅳ98 on the column Ⅰ9 to ensure that the two planes A are on the same plane, the flatness error is not more than 0.08mm / 2000mm, and the parallelism error of the two sides is not more than 0.08mm / 2000mm. Drill the positioning pin hole and install it. Cylindrical pin VII100.

[0027] Install the guide rail Ⅰ86 and guide rail Ⅱ90 on the column Ⅱ50, ensure that the two planes B are on the same plane, the flatness error is not more than 0.08mm / 2000mm, and the parallelism error of the two sides is not more than 0.08mm / 2000mm, drill the positioning pin hole, install Cylindrical pin X109.

[0028] Install the column ...

Abstract

The invention discloses an intermediate-frequency quenching machine tool driven by motors. The intermediate-frequency quenching machine tool comprises a base which is fixedly connected with a stand column I and a stand column II which are perpendicular to the base. A quenching device lifting platform is arranged on the stand column I, a lower centre rotating device is fixed to the lower portion of the stand column II, and an upper centre lifting device is arranged on the upper portion of the stand column II. According to the intermediate-frequency quenching machine tool, joist steel and box iron are used as the stand columns of the machine tool, ascending and descending of a sensor and ascending and descending of an upper centre are achieved through rectangular guide rails, the rigidity of a machine tool body and the guide rails is improved, and therefore the quenching stability and precision are improved. The motors driving a workpiece to rotate are arranged on the back faces of the stand columns, water and moisture resistance is effectively conducted, and the damage rate of the motors is greatly reduced. A deep groove ball bearing and a thrust ball bearing are installed at the lower end of a screw rod, the screw rod is stressed axially to act on the thrust ball bearing, and therefore axial movement of the screw rod is effectively prevented, and the deep groove ball bearing and a screw rod pair are protected.

Description

technical field [0001] The invention relates to a motor-driven intermediate frequency quenching machine tool, which is applied to the heat treatment of shaft parts in the machining industry, and relates to mechanical basic parts. Background technique [0002] Shaft parts are commonly used parts in various machinery. After the surface is quenched by intermediate frequency, the hardness is significantly improved, and the wear resistance of the surface is improved, thereby prolonging the service life of the parts. The existing intermediate frequency quenching machine tools use bent steel plates as columns, and the rigidity of the machine tool is poor; the cylindrical optical axis is used as the guide rail, which has poor rigidity and is easy to deform; these two reasons lead to obvious vibration of the workpiece during work, which affects the quenching accuracy; The motor that rotates the workpiece is under the workpiece, so it is not easy to be waterproof and easily affected b...
