Description

TECHNICAL FIELD

[0001] The utility model relates to the field of part processing especially relates to a new energy axle housing carburizing shielding auxiliary tool. BACKGROUND

[0002] Carburizing is a common heat treatment process of metal material, which refers to the process of making carbon atoms penetrate into the surface layer of steel. It is also to make the surface layer of low-carbon steel workpiece have high-carbon steel surface layer, and then quenching and low-temperature tempering to make the surface layer of workpiece have high hardness and wear resistance. The effective depth of carburizing can be controlled to 0.4-0.8mm. However, if the part structure that does not need carburizing is carburized, the carburized layer needs to be removed after carburizing, which increases the workload of the part. SUMMARY

[0003] The utility model solves the technical problem that the part structure does not need carburizing.

[0004] To solve the above technical problem, the utility model provides a new energy axle housing carburizing shielding auxiliary tool, which comprises a sleeve, a first sealing plate is arranged at one end of the sleeve, a second sealing plate is arranged at the other end of the sleeve, a through hole is arranged on the second sealing plate, the second sealing plate is sealingly connected with a shaft penetrating through the through hole, a connecting rod penetrating through the shaft is arranged on the first sealing plate, a gland pressing one end of the shaft and a nut are arranged at one end of the connecting rod.

[0005] In the preferred scheme, a bottom hole not penetrating through is arranged on the first sealing plate, and the connecting rod is screw-connected on the bottom hole.

[0006] In the preferred scheme, a notch is arranged around the first sealing plate, the sleeve is screw-connected in the notch, and high-temperature-resistant sealing glue is further arranged at the bottom of the sleeve in contact with the notch.

[0007] In the preferred scheme, the second sealing plate is screw-connected with the sleeve, high-temperature-resistant sealing glue is arranged at the place where the second sealing plate contacts with the end surface of the sleeve; the through hole is gap-fitted with the shaft, and high-temperature-resistant sealing glue is arranged in the through hole.

[0008] The utility model has the advantages that the utility model sets a new energy axle housing carburizing shielding auxiliary tool, the part structure of the shaft that does not need carburizing is installed in the sleeve by setting a sealing sleeve assembly, which protects the part structure of the shaft that does not need carburizing. BRIEF DESCRIPTION OF DRAWINGS

[0009] The utility model will be further described in connection with the drawings and examples as follows:

[0010] Figure 1 It is the installation sectional view structure diagram of the utility model example.

[0011] Reference signs: shaft 101; sleeve 1; first sealing plate 12; bottom hole 121; notch 122; second sealing plate 13; through hole 131. DETAILED DESCRIPTION

[0012] Please refer to Figure 1 As shown in the drawings, the embodiment of the application provides a technical scheme: a new energy bridge shell carburizing shielding auxiliary tool, comprising a sleeve 11, a first sealing plate 12 is arranged at one end of the sleeve 11, a second sealing plate 13 is arranged at the other end of the sleeve 11, a through hole 131 is arranged on the second sealing plate 13, the second sealing plate 13 is sealingly connected with the shaft 101 passing through the through hole 131, a connecting rod 14 passing through the shaft 101 is arranged on the first sealing plate, a gland and a nut 15 pressing one end of the shaft 101 are arranged at one end of the connecting rod 14.

[0013] In this way, the part of the shaft 101 that does not need to be carburized is installed in the sleeve 11, and the part that needs to be carburized is protruding out of the sleeve 11, so that carbon atoms cannot enter the sleeve 11 to carburize part of the shaft 101, achieving the purpose of process requirement and avoiding the need for processing the excess carburized layer in the later stage.

[0014] In the preferred scheme, a bottom hole 121 not penetrating through the first sealing plate 12 is arranged, and the connecting rod 14 is threadedly connected to the bottom hole 121.

[0015] The bottom hole 121 can be provided with a thread, and the connecting rod 14 is provided with a thread, and the two are connected through the threads.

[0016] In the preferred scheme, a notch 122 is arranged around the first sealing plate 12, and the sleeve 11 is threadedly connected in the notch 122, and high-temperature-resistant sealing glue is further arranged at the bottom of the sleeve 11 in contact with the notch 122.
