Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and in particular to a tooling for loading gear parts for carburizing and quenching. Background Technology

[0002] Gears are widely used transmission components. Their meshing mechanism requires gears to possess characteristics such as low impact resistance, low vibration and noise, high strength, good wear resistance, and long service life. Therefore, during gear manufacturing, heat treatment of the gear surface profile is necessary to improve its strength and wear resistance.

[0003] Gear parts require carburizing and quenching processes during production to improve surface hardness and wear resistance. The rationality of the loading tooling directly affects the uniformity of carburizing, the amount of quenching deformation, and production efficiency. The traditional quenching method involves using a carburizing furnace to quench gear parts.

[0004] However, the traditional quenching method uses a stacked placement, with the gear tooth surfaces in contact with each other, resulting in insufficient carburized layer thickness in the contact area. Furthermore, the gears need to be removed one by one after quenching, which is quite troublesome and reduces the gear unloading efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a tooling for loading gear parts for carburizing and quenching, which solves the problems of traditional quenching methods that use stacked placement, where gear tooth surfaces come into contact with each other, resulting in insufficient carburized layer thickness in the contact area, and the need to remove the gears one by one after quenching, which is troublesome and reduces the unloading efficiency of the gears.

[0006] To achieve the above objectives, this utility model provides a tooling for loading gear parts for carburizing and quenching, including a load-bearing base, a height adjustment component at the upper end of the load-bearing base, a bearing rod between the height adjustment components, a plurality of hanging rod limiting grooves evenly arranged at the upper end of the bearing rod, the hanging rod limiting grooves being spaced at the same distance, and a gear limiting component being arranged inside the hanging rod limiting groove.

[0007] The height adjustment component includes four support rods. The four support rods are located at the four corners of the upper end of the load-bearing base. Several spacing adjustment sliders are slidably arranged at the outer ends of the four support rods. The bearing rods are arranged between the spacing adjustment sliders. By sliding the spacing adjustment sliders on the support rods, the spacing between each layer of gears can be easily adjusted.

[0008] The outer end of the spacing adjustment slider is provided with a positioning hole, and a positioning bolt is threaded into the inside of the positioning hole. By inserting the positioning bolt into the positioning hole and tightening it, the height of the spacing adjustment slider can be fixed.

[0009] The gear limiting assembly includes a gear hanger rod, with a gear hanger rod inside the hanger rod limiting groove. The two ends of the gear hanger rod are connected to limiting blocks by threads. The outer end of the gear hanger rod is evenly provided with several gear limiting grooves. The gear hanger rod is designed to facilitate hanging gears on it, and the gear limiting grooves are designed to limit the gears, ensuring that the spacing between gears is the same, preventing contact between gears, and ensuring that the tooth surfaces are fully exposed.

[0010] Each of the four support rods has a fixing rod at its upper end, and a lifting ring is provided at the upper end of the fixing rod. The lifting ring facilitates the use of lifting equipment to lift the entire fixture into the carburizing and quenching furnace for quenching.

[0011] The load-bearing base has four support feet evenly distributed on its outer end. The lower end of each of the four support feet is provided with an anti-slip seat. The load-bearing base is placed stably by the four support feet. The anti-slip seat at the lower end of the support feet increases the friction and prevents the tooling from sliding.

[0012] The gear rod is engaged with the front and rear ends of the gear rod in the front and rear rod limiting grooves. The gear limiting grooves at the outer ends of the gear rod are spaced at the same distance. The diameter of the limiting block is larger than the rod limiting groove.

[0013] This utility model discloses a tooling for loading gear parts for carburizing and quenching.

The two ends of the gear hanger are engaged in the hanger limiting grooves of the front and rear support rods.

[0023] In this embodiment, the preferred height adjustment component 2 includes four support rods 21. The four corners of the upper end of the load-bearing base 1 are provided with four support rods 21. The outer ends of the four support rods 21 are slidably provided with a plurality of spacing adjustment sliders 22. The bearing rods 3 are arranged between the spacing adjustment sliders 22. By sliding the spacing adjustment sliders 22 on the support rods 21, it is convenient to adjust the spacing between each layer of gears.

[0024] In this embodiment, the outer end of the preferred spacing adjustment slider 22 is provided with a positioning hole 23, and a positioning bolt 24 is threadedly connected inside the positioning hole 23. By inserting the positioning bolt 24 into the positioning hole 23 and tightening it, the height of the spacing adjustment slider 22 can be fixed.

[0025] In this embodiment, the preferred gear limiting component 5 includes a gear hanging rod 51. The gear hanging rod 51 is provided inside the hanging rod limiting groove 4. The two ends of the gear hanging rod 51 are connected to limiting blocks 52 by threads. The outer end of the gear hanging rod 51 is evenly provided with a plurality of gear limiting grooves 53. The setting of the gear hanging rod 51 facilitates the hanging of gears on the gear hanging rod 51. The setting of the gear limiting grooves 53 facilitates the limiting of gears, so that the spacing between gears is the same, avoiding contact between gears and ensuring that the tooth surface is fully exposed.

[0026] In this embodiment, preferably, the upper ends of the four support rods 21 are all provided with fixing rods 6, and the upper ends of the fixing rods 6 are provided with lifting rings 7. The lifting rings 7 facilitate the use of lifting equipment to lift the entire tooling into the carburizing and quenching furnace for quenching.

[0027] In this embodiment, the outer end of the preferred load-bearing base 1 is evenly provided with four support feet 8, and the lower end of the four support feet 8 is provided with an anti-slip seat 9. The load-bearing base 1 is placed stably by the four support feet 8, and the anti-slip seat 9 at the lower end of the support feet 8 increases the friction and prevents the tooling from sliding.

[0028] In this embodiment, preferably, the front and rear ends of the gear rod 51 are engaged in the rod limiting grooves 4 on the front and rear sides, the gear limiting grooves 53 at the outer ends of the gear rod 51 are spaced at the same distance, and the diameter of the limiting block 52 is larger than the rod limiting groove 4.

[0029] Working principle:

[0030] The load-bearing base 1 is stably placed by four support feet 8. The anti-slip seats 9 at the lower end of the support feet 8 increase the friction and prevent the tooling from sliding. Four support rods 21 are fixed at the four corners of the upper end of the load-bearing base 1. According to the gear height requirements, the spacing adjustment sliders 22 on the sliding support rods 21 are moved to the appropriate position. Multiple spacing adjustment sliders 22 can be set on each support rod 21. The spacing adjustment sliders 22 are fixed by tightening the positioning bolts 24 through the positioning holes 23. Then, the bearing rods 3 are installed between the corresponding spacing adjustment sliders 22 on both sides to form a multi-layer bearing structure. The two ends of the gear hanging rod 51 are inserted into the hanging rod limiting grooves 4 of the front and rear bearing rods 3. The hanging rod limiting grooves 4 are evenly distributed to ensure that the gear hanging rod 51 is horizontal and stable. Limiting blocks 52 are installed at both ends of the gear hanger 51. The diameter of the limiting blocks 52 is larger than that of the hanger limiting groove 4 to prevent the gear hanger 51 from falling out of the groove. The gear parts are sequentially fitted onto the gear hanger 51. The inner hole of the gear is clearance-fitted with the gear hanger 51. The teeth of each gear are inserted into the corresponding gear limiting groove 53. The gear limiting grooves 53 are evenly spaced, which can separate 5-8 gears to avoid contact between gears and ensure that the tooth surface is fully exposed. The entire fixture is lifted into the carburizing and quenching furnace using the lifting ring 7 at the upper end of the fixing rod 6. After processing, the fixture is lifted out, and the limiting blocks 52 at both ends of the gear hanger 51 are released. The gear hanger 51 and the gears can then be removed from the hanger limiting groove 4 to achieve batch unloading.
