[0001] The utility model relates to the technical field of gear processing, in particular to a gear tooth surface quenching device. Background Art

[0002] Gear tooth surface quenching device is a device specially used for quenching gear tooth surface. The quenching device quickly heats and cools the gear tooth surface to improve its hardness and wear resistance. It is widely used in the automotive, steel, metallurgy, mining, aerospace, machine tools and other industries.

[0003] Existing gear tooth surface quenching devices, such as a large gear continuous quenching and cooling device disclosed in publication number CN220335257U, have the advantage of being able to perform all-round quenching operations on different surfaces of large gears by setting a quenching mechanism. However, this quenching and cooling device has a supporting structure composed of a rotating shaft, which makes it only convenient to install gears with circular holes of corresponding sizes in the gears, but is inconvenient to install and process gears such as gear rings and gear discs, resulting in insufficient adaptability. To this end, we propose a gear tooth surface quenching device. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0025] A gear tooth surface quenching device provided by some embodiments of the present invention will be described below with reference to the accompanying drawings. Example 1

[0026] Combine Figure 1-5 As shown, the present invention provides a gear tooth surface quenching device, comprising: a quenching device 100, an adjusting component 200; the quenching device 100 comprises a rotating disk 101 at its upper end, three groups of brackets 102 arranged and fixedly installed on the rotating disk 101, and a quencher 103 installed on one side thereof; the adjusting component 200 comprises a slide 201 provided in each bracket 102, a slider 202 movably installed in the slide 201, a restraining rod 203 movably installed at the inner end of the upper part of the slider 202, a top block 204 fixedly installed on the top of the restraining rod 203, a toothed belt 205 fixedly installed on both sides of the top of the bracket 102, a rack 206 fixedly installed on the bottom of the top block 204, a wiring harness 207 fixedly connected to one side of the slider 202 in the slide 201, and an outer portion of the bracket 102. A scale 215 is fixedly installed on each side of the rotating disk 101, and an indicator needle 216 is fixedly installed on one side of the top block 204. A winding disk 208 is movably installed at the center of the upper end of the rotating disk 101, and one end of the wiring harness 207 is fixed on the winding disk 208. A reduction motor 209 is fixedly installed at the bottom of the winding disk 208, and a protective cover 210 is movably installed on the outer end of the reduction motor 209. The reduction motor 209 and the protective cover 210 are fixedly connected to the rotating disk 101. A first spring 211 is fixedly installed between the outer side of the slider 202 in the slide 201 and the bracket 102, and a second spring 212 is movably installed in the slider 202. A positioning ring 213 is fixedly installed on the inner side wall of the slider 202, and rollers 214 are movably installed on both sides of the lower part of the slider 202.

[0027] Specifically, the gear tooth surface quenching device is a device that quickly heats and cools the gear tooth surface to improve its hardness and wear resistance. The top blocks 204 on the top of the three sets of brackets 102 in this quenching device 100 can automatically and synchronously adjust the top blocks 204 on the three sets of brackets 102 according to the radius of the gear to be quenched through the winding disk 208 driven by the central reduction motor 209 of the rotating disk 101, the indicator needle 216 on the outside of the top block 204 and the scale 215 on the outside of the bracket 102. 4, thereby increasing the convenience and accuracy of adjusting the position of the top block 204 in the gear support. At the same time, after the top block 204 is pressed by the gear, the rack 206 at the bottom will also be engaged with the upper ends of the toothed belts 205 on both sides of the bracket 102, thereby increasing the stability of the top block 204 in the support. The rack 206 and the toothed belt 205 are both small-sized structures. Even after the rack 206 and the toothed belt 205 are misaligned, they can still stably support the upper gear through a slight extrusion and misalignment movement. The rollers 214 movably mounted at both ends of the slider 202 in the groove 201 can also ensure the ease and stability of the slider 202 when being pulled by the harness 207, thereby reducing the friction during the sliding of the slider 202 and improving its service life. The protective cover 210 at the outer end of the reduction motor 209 is mainly used for providing safety protection on the outside of the reduction motor 209 when in use. The first spring 211 fixedly connected between the bracket 102 and the slider 202 in the slide groove 201 is mainly used for returning the top block 204 on the bracket 102 after use, thereby facilitating subsequent re-pulling and adjustment. The second spring 212 supporting the restraining rod 203 in the slider 202 is mainly used for supporting and separating the top block 204 on the slider 202 when not in use, so as to avoid engagement between its bottom rack 206 and the toothed belt 205 on the bracket 102. The positioning ring 213 fixedly mounted on the inner side wall of the slider 202 is mainly used for positioning the pressing position of the top block 204, thereby ensuring the stability of the top block 204 when being pressed.

[0028] The working principle and use process of this utility model:

[0029] When installing during gear quenching processing, first measure the radius of the gear to be processed, and start the reduction motor 209 at the center of the rotating disk 101 after the gear radius is measured. After the reduction motor 209 is started, the winding disk 208 at the top will be rotated. During the rotation of the winding disk 208, the wire harness 207 in the three groups of brackets 102 will be synchronously wound. During the winding of the wire harness 207, the sliders 202 and the top blocks 204 in the three groups of brackets 102 are synchronously pulled inward through the rollers 214 at both ends, and the position of the indicator needle 216 on the outside of the top block 204 on the scale 215 at the outer end of the bracket 102 is observed. After the three groups of top blocks 204 are adjusted to the same radius as the gear to be processed, the reduction motor 209 can be turned off to place the gear to be processed on the upper end of the three groups of adjusted top blocks 204. After the gear is placed, it will press the top block 204 at the bottom by its own weight. After the top block 204 is pressed, the rack 206 on one side of its bottom will engage with the toothed belt 205 on the bracket 102, thereby locking the top block 204 after being pressed to ensure the stability of the gear to be processed during placement. After the gear is placed, the tooth surface is quenched by the quencher 103 on the quenching equipment 100.

[0030] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
