Description

Technical Field

[0001] The invention relates to the technical field of surface heat treatment of mechanical metal parts, in particular to a surface heat treatment processing device for mechanical metal parts. Background Art

[0002] Mechanical metal parts are an indispensable part of mechanical engineering. They are usually made of various metal materials and are used to realize various functions and performances of machinery. Mechanical metal parts include shafts, gears, screws and nuts, bearings and other metal parts. After production, mechanical metal parts need to undergo surface heat treatment before they can be put into use.

[0003] In mechanical engineering, heat treatment is a key technical means to optimize the performance of metal components and enhance their durability. In particular, surface heat treatment focuses on significantly improving the hardness, wear resistance and corrosion resistance of metal components by adjusting the physical and chemical properties of the surface, thereby extending their service life. For key transmission components such as gears, existing surface heat treatment technologies include surface quenching, carburizing quenching, induction heating quenching and other methods. As an efficient and precise heat treatment method, induction heating quenching works based on the electromagnetic induction phenomenon. In this process, high-frequency current passes through the inductor to excite eddy currents on the surface of the gear. The heat generated by these eddy currents quickly heats the surface of the gear to the austenite transformation temperature, and then quickly cools it.

[0004] However, when the gears are heat treated by induction heating quenching, the gears can only be heat treated individually, and when the gear surfaces are heat treated, the gears cannot be quickly installed and fixed, resulting in reduced heat treatment efficiency of the gears.

[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] Embodiment: A surface heat treatment device for a mechanical metal part, such as Figure 1-Figure 7 As shown, it includes a mounting body 1 and a heating ring 6 arranged above the mounting body 1. By providing the heating ring 6, the surface of the gear can be quickly heated to achieve heat treatment of the gear surface. It is worth noting that the heating ring 6 is a prior art that generates eddy currents on the gear surface through the principle of electromagnetic induction, so that the gear surface is quickly heated to the austenitizing temperature. A rotating part 2 is provided inside the mounting body 1. By providing the rotating part 2, the gear that needs to be heat treated can be driven to change position and can be driven to rotate, thereby ensuring the purpose of uniform heating of the gear surface.

[0032] Among them, the rotating part 2 includes a driving tooth 201, and a motor 202 is fixedly installed on the lower surface of the driving tooth 201. By setting the driving tooth 201 and the motor 202, the driving tooth 201 can be driven to rotate synchronously by the rotation of the motor 202; it is worth noting that only one-fourth of the surface of the driving tooth 201 is provided with meshing teeth; a protrusion 203 is fixedly installed on the upper surface of the driving tooth 201, and the protrusion 203 is an arc-shaped structure. By setting the protrusion 203, a lifting effect can be achieved; both ends of the protrusion 203 are provided with inclined surfaces, and the inclined surfaces are smoothly connected to the upper surface of the driving tooth 201. By setting the inclined surfaces smoothly connected to the upper surface of the driving tooth 201, the parts in contact with the upper surface of the driving tooth 201 can be moved to the upper end of the protrusion 203 through the inclined surfaces, thereby achieving the purpose of lifting.

[0033] Among them, a baffle 204 is fixedly installed on the upper surface of the protrusion 203, and the shape of the baffle 204 is adapted to the protrusion 203. By setting the baffle 204, it can play a guiding and limiting role; an outward expansion opening 2041 is opened at one end of the baffle 204, and by opening the outward expansion opening 2041, it is convenient for parts to enter the interior of the baffle 204 from the outward expansion opening 2041; the inner wall of the baffle 204 is provided with teeth 205, and by providing the teeth 205, it can play a role of meshing drive.

[0034] Combined with attachment Figure 1 -Attached Figure 7 , the internal rotation of the installation body 1 is equipped with a transposition mechanism 3 for transposing the gear to be heat treated, so that the gear can be automatically transposed during the heat treatment process of the gear, thereby accelerating the processing efficiency of the gear; the transposition mechanism 3 includes a turntable 301, which is embedded in the interior of the installation body 1 and can rotate. By setting the turntable 301, the gear to be heat treated can be driven to rotate to achieve the purpose of transposition; a hollow rod 302 is fixedly mounted on the lower surface of the turntable 301, and the lower end of the hollow rod 302 is rotatably connected to the bottom surface of the installation body 1. By setting the hollow rod 302, it can play a role of connection and limit, so that the transposition mechanism 3 can rotate normally;

[0035] The top of the rotary table 301 is provided with a screw thread 303, and the screw thread 303 is fixed to the bottom surface of the rotary table 301. The screw thread 303 is fixed to the bottom surface of the rotary table 301, and the screw thread 303 is fixed to the bottom surface of the rotary table 301. The heating ring 6 is connected to the positioning rod 303, so that the heating ring 6 is in a fixed position; the surface of the hollow rod 302 is sleeved with a driven tooth 304, and the driven tooth 304 is meshed with the driving tooth 201, so that when the driving tooth 201 rotates, it can drive the driven tooth 304 to rotate synchronously, and then drive the turntable 301 to start rotating; it is worth noting that since only one-fourth of the surface of the driving tooth 201 is provided with meshing teeth, it can only drive the driven tooth 304 to rotate one-fourth, and the area on the surface of the driving tooth 201 where the meshing teeth are provided can be set as needed.

[0036] Combined with attachment Figure 1 -Attached Figure 7 By setting a lifting mechanism 4 for lifting the gears to be heat treated, each group of gears can be quickly lifted into the interior of the heating ring 6 for heating after being shifted; the lifting mechanism 4 includes multiple groups of carrier plates 401, and the multiple groups of carrier plates 401 are equidistantly distributed in the grooves opened on the surface of the turntable 301. The plane structure of the carrier plates 401 is an inverted T-shaped structure. By setting the carrier plates 401, the gears to be heat treated can be carried; a cavity 4011 is opened inside the carrier plate 401, and multiple groups of recesses 4012 are equidistantly opened on the surface of the carrier plate 401, and the recesses 4012 are connected to the cavity 4011 through through holes. By setting the recesses 4012, it can play a storage role.

[0037] Among them, a round rod 402 is fixedly installed at the lower end of the carrier plate 401, which can play a guiding and limiting role; a matching tooth 403 is fixedly installed at the lower end of the round rod 402, and the matching tooth 403 can enter the interior of the baffle 204 and can be engaged with the tooth 205, and then can rotate under the action of the tooth 205 and drive the round rod 402 to rotate synchronously; an insertion rod 404 is inserted into the interior of the round rod 402, and by setting the insertion rod 404, the round rod 402 can be raised and lowered inside; it is worth noting that the lower end of the insertion rod 404 is located below the matching tooth 403;

[0038] Among them, a spherical head 405 is fixedly installed at the lower end of the insertion rod 404, and the surface of the spherical head 405 is in contact with the upper surface of the driving tooth 201, and the surface of the spherical head 405 is squeezed and fitted with the inclined surfaces opened at both ends of the protrusion 203. By setting the spherical head 405, when the driving tooth 201 rotates synchronously with the motor 202, it can better contact with the inclined surface and form a backlog effect, so that the spherical head 405 can drive the insertion rod 404 to rise and fall inside the round rod 402; a disc 406 is fixedly installed at the upper end of the insertion rod 404, and by setting the disc 406, it can move synchronously with the insertion rod 404; the disc 406 is elastically connected to the inner wall of the cavity 4011 through a return spring 4061. By setting the return spring 4061, when the disc 406 moves up synchronously with the insertion rod 404, the return spring 4061 will begin to stretch, causing the return spring 4061 to deform and generate a reaction force, so as to subsequently drive the disc 406 to reset.

[0039] Combined with attachment Figure 1 -Attached Figure 7 , also includes a positioning member 5 for fixing the gear to be heat treated, so that the gear can be fixed during the heat treatment to prevent the gear from moving during the heat treatment process, resulting in uneven heating and deformation; the positioning member 5 includes a plurality of connecting rods 501 movably connected to the surface of the disk 406. By setting the connecting rods 501, it can play a connecting role; the end of the connecting rod 501 is movably connected to the telescopic rod 502, and the end of the telescopic rod 502 passes through the through hole and extends to the inside of the recess 4012. By setting the telescopic rod 502, when the disk 406 moves upward, it will drive the connecting rod 501 to move upward and rotate synchronously, and begin to push the telescopic rod 502 to begin to extend from the inside of the cavity 4011; it is worth noting that by setting the telescopic rod 502, gears of different specifications can be fixed, increasing the practicality of the device; the end of the telescopic rod 502 is fixedly installed with an arc block 503. By setting the arc block 503, it will move synchronously with the telescopic rod 502 and begin to extend to fix the gear to be heat treated.

[0040] Specifically, when heat treating the gears, the gears are first placed one by one on the surface of multiple groups of carrier plates 401, and then the motor 202 is started, and the driven teeth 304 engaged with the driving teeth 201 start to rotate a quarter of a turn, so that one group of gears can move to the bottom of the heating ring 6; as the motor 202 continues to rotate, the driving teeth 201 and the driven teeth 304 are no longer engaged, and at the same time, the inclined surface opened at one end of the protrusion 203 will begin to contact and squeeze the spherical head 405. When the spherical head 405 moves to the middle position of the inclined surface, the spherical head 405 will drive the insertion rod 404 and the disc 406 inside the round rod 402. The spherical head 405 moves upward synchronously, and when the spherical head 405 moves to the middle position of the inclined surface, the upper end of the spherical head 405 begins to contact the lower surface of the matching tooth 403, and the upward-moving disc 406 begins to stretch the reset spring 4061, and at the same time drives the multiple groups of connecting rods 501 movably connected to the upper surface of the disc 406 to start rising and rotating. The rising and rotating connecting rods 501 begin to squeeze the telescopic rods 502 movably connected at the ends to start moving from the inside of the cavity 4011 to the outside, and drive the arc block 503 that is initially located inside the notch 4012 to move synchronously, and begin to contact the inner wall of the gear to be heat-treated, thereby fixing the gear;

[0041] After the gear is fixed, as the driving tooth 201 continues to rotate, the spherical head 405 will move from the middle position of the inclined surface to the upper end of the protrusion 203, and then drive the round rod 402 and the carrier plate 401 to start moving upward synchronously, so that the fixed gear begins to enter the interior of the heating ring 6 for heating; when the spherical head 405 moves to the upper end of the protrusion 203, the matching tooth 403 will enter the interior of the baffle 204 from the outer expansion opening 2041, and at the same time, the matching tooth 403 will also begin to contact and mesh with the tooth 205, so that as the driving tooth 201 rotates, the matching tooth 403 will drive the round rod 402, the carrier plate 401 and the fixed gear to start rotating inside the heating ring 6, so that the gear can be heated evenly, thereby accelerating the heat treatment efficiency of the gear;

[0042] When the driving tooth 201 drives the other set of inclined surfaces of the protrusion 203 to contact the spherical head 405, as the driving tooth 201 rotates, the mating tooth 403 will begin to separate from the tooth 205. At the same time, the spherical head 405 begins to drive the insertion rod 404 and the disc 406 to move down and reset, and drives the telescopic rod 502 and the arc block 503 to reset through the connecting rod 501 movably installed on the surface of the disc 406, thereby releasing the fixation of the gear that has been heat-treated, so that the gear can be removed and replaced with a new gear to be heat-treated.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
