Description

Technical Field

[0001] This utility model relates to the field of induction hardening technology, specifically a turntable device for induction hardening. Background Technology

[0002] In induction hardening, turntables often serve to support, fix, and rotate the workpiece. They are widely used in the hardening of large parts such as the inner and outer rings of wind turbine bearings and rotary gear rings. Currently, bearings and gear rings are becoming increasingly larger, with more and more large-diameter bearings and gear rings being widely used, posing challenges to the turntable's load-bearing capacity and rotational accuracy. In previous turntables, the maximum diameter they could support was often 6 to 8 meters, and the weight of the workpiece would cause slight deformation at the end of the turntable support arm, affecting the indexing accuracy of the turntable and the hardening quality. Sometimes, the turntable's torque transmission was insufficient, resulting in insufficient workpiece rotation speed, further impacting the hardening quality.

[0003] Chinese patent documents “A Single-Gantry Quenching Machine Tool for Induction Quenching” (patent application number: 202321529118.4) and “A Quenching Equipment for Slewing Bearing Raceway Without Soft Belt” (patent application number: 201910546961.5) respectively disclose a turntable device, but the above-mentioned turntable devices have not solved the technical problems of load-bearing capacity and rotational accuracy. Utility Model Content

[0004] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a turntable device for induction hardening, which can solve the problems of load-bearing capacity and rotation accuracy, and can be applied to workpieces with diameters of 3-20 meters.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a turntable device for induction hardening, comprising a turntable, at least one annular ground rail and several support arms; each annular ground rail is arranged concentrically around the outside of the turntable, and the diameter of each annular ground rail is larger than the diameter of the turntable; each support arm is radially distributed on the turntable, and the end of each support arm extends out of the turntable and is provided with a support roller corresponding to each annular ground rail.

[0006] A further improvement is that the turntable includes a base, a turntable is provided on the top of the base, and a drive component for driving the turntable to rotate is provided on the side of the base.

[0007] A further improvement is that the edge of the turntable is provided with reinforcing arms corresponding to each support arm.

[0008] A further improvement is that: a radial guide rail is provided on the support arm, and a slide block is slidably provided on the radial guide rail, and a support column for supporting and positioning the workpiece is provided on the slide block.

[0009] A further improvement is that at least one support arm has a scale on its side, and the slide has a pointer corresponding to the scale.

[0010] A further improvement is that a sealing plate is installed between each pair of adjacent support arms.

[0011] A further improvement is that a mounting plate is provided at the bottom of the support arm.

[0012] A further improvement is that the circular ground track is composed of several arc-shaped splicing bodies.

[0013] A further improvement is that the top of the arc-shaped splice is provided with an arc-shaped slide rail, and the bottom of the arc-shaped splice is provided with feet and anchors.

[0014] A further improvement is that the arc-shaped splice body has weight-reducing holes.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. In this utility model, a support roller is installed on the bottom surface of the support arm, which can maintain the stability of the workpiece during the rotation of the workpiece and improve the quenching quality; the support roller is on the turntable ground rail and plays a role in sharing part of the workpiece weight at the far end of the support arm, which can increase the maximum load capacity of the turntable device as a whole; the rolling of the support roller on the ground rail reduces the torque of the support arm, improves the rotation accuracy of the turntable device, and improves the quenching quality.

[0017] 2. In this utility model, each annular ground rail is arranged concentrically around the outside of the turntable, which reduces the workpiece mass carried by a single support arm and improves the indexing accuracy of the turntable device. Attached Figure Description
