Description

Technical Field

[0001] The utility model relates to the technical field of camshaft processing, in particular to a supporting structure for camshaft quenching. Background Art

[0002] High-frequency quenching is a metal heat treatment method. The workpiece is placed in an inductor, which is generally a hollow copper tube that inputs medium-frequency or high-frequency alternating current (1000-300000Hz or higher). An induced current of the same frequency is generated in the workpiece. The distribution of this induced current in the workpiece is uneven. It is strong on the surface, very weak inside, and close to zero in the core. By using this skin effect, the surface of the workpiece can be quickly heated. The surface temperature rises to 800-1000℃ within a few seconds, while the temperature of the core rises very little, and then it is quickly cooled to complete the quenching. Quenching can produce martensitic structure in materials such as steel, thereby increasing its hardness and strength, as well as improving its wear resistance.

[0003] A Chinese invention patent [Publication No.: CN114561521A] discloses a high-frequency quenching device and a quenching process for a motor shaft, comprising a conveyor belt and a workbench arranged above the conveyor belt, a plurality of placement seats are evenly arranged on the conveyor belt, a clamping mechanism is slidably installed on the workbench, the clamping mechanism comprises a power unit, a support assembly, a clamping assembly and a locking assembly, the power unit is arranged on the workbench, the support assembly is slidably arranged on the workbench, the clamping assembly is arranged on the workbench and the support assembly, the locking assembly is arranged on the clamping assembly and the workbench, a high-frequency sensor is arranged at the bottom of the workbench, and a water pipe is arranged on one side of the high-frequency sensor on the workbench.

[0004] When the device is used to quench the camshaft, since the directions of the cams of the camshaft are not consistent, it is difficult to ensure the levelness of the camshaft after it is placed on the placement seat, resulting in difficulty in the clamping assembly to clamp the camshaft. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a support structure for camshaft quenching to solve the problem in the prior art that it is difficult to ensure the levelness of the camshaft after it is placed on the placement seat, resulting in difficulty in clamping the camshaft by the clamping assembly.

[0006] The utility model solves the above technical problems through the following technical means:

[0031] like Figure 1-Figure 3 As shown, a camshaft quenching support structure of the utility model includes a plurality of placement units 2 arranged on a conveyor belt 1, the placement unit 2 includes two placement components 3 with the same structure, the two placement components 3 are respectively located on both sides of the conveyor belt 1, and the placement components 3 include a placement seat 4, a mounting member 5 and a positioning rod 6. Among them,

[0032] A support groove 41 is provided on the placement seat 4, and the support groove 41 is used to place the shaft body of the camshaft 10. By supporting the shaft body of the camshaft 10, the axis of the camshaft 10 can be determined to ensure that the camshaft 10 is placed horizontally, so that the clamping assembly can clamp the camshaft 10 smoothly.

[0033] The mounting member 5 is fixedly mounted on the conveyor belt 1, and a through hole 42 is provided on the placement seat 4. The mounting member 5 is inserted into the through hole 42. The placement seat 4 is slidably sleeved on the mounting member 5 through the through hole 42, so as to realize the sliding connection between the placement seat 4 and the mounting member 5. A driving member is provided on the mounting member, and the driving member is used to drive the placement seat to slide. In this embodiment, the driving member is an elastic member, i.e., a compression spring. One end of the elastic member 51 abuts against the placement seat 4, and the other end abuts against the conveyor belt 1. In other embodiments, a cylinder, a motor plus a screw rod, etc. can be used as a driving member, but the cost is relatively high. In this embodiment, by providing the elastic member 51, after the clamping assembly clamps the camshaft 10, the placement seat 4 only needs to be moved downward to make the placement seat 4 disengage from the obstruction of the camshaft 10, and after the placement seat 4 moves downward, it can be automatically reset, effectively reducing the cost.

[0034] The first inclined surface 43 and the second inclined surface 44 are respectively provided on both sides of the placement seat 4. When the cam of the camshaft 10 clamped by the clamping assembly abuts against the placement seat 4, the placement seat 4 can be automatically pushed downward by the first inclined surface 43 or the second inclined surface 44, so that the placement seat 4 is freed from the obstruction of the cam of the camshaft 10, so that the clamping assembly can smoothly clamp the camshaft 10 and move, realizing the automatic downward movement of the placement seat 4, further reducing the cost.

[0035] The positioning rod 6 is fixedly mounted on the conveyor belt 1 , and a positioning hole 45 is opened on the placement seat 4 . The positioning rod 6 is slidably inserted into the positioning hole 45 to prevent the placement seat 4 from rotating with the mounting member 5 as the rotation axis, thereby ensuring the supporting effect of the placement seat 4 .

[0036] In this embodiment, a first limiting ring 52 is provided at the top of the mounting member 5, and a second limiting ring 421 is provided at the bottom of the through hole 42. It can be understood that the outer diameter of the first limiting ring 52 is larger than the outer diameter of the second limiting ring 421, and the first limiting ring 52 and the second limiting ring 421 are used to prevent the placement seat 4 from detaching from the mounting member 5.

[0037] The working principle of this utility model:

[0038] When the camshaft 10 is placed on the placement unit 2 , the shaft bodies at both ends of the camshaft 10 are respectively placed in the supporting grooves 41 of the placement seats 4 on both sides of the conveyor belt 1 .

[0039] The clamping assembly clamps the camshaft 10 to move. When the cam of the camshaft 10 abuts against the placement seat 4, the cam of the camshaft 10 squeezes the first inclined surface 43 or the second inclined surface 44, causing the placement seat 4 to compress the elastic member 51 and move downward along the axial direction of the mounting member 5 until the cam of the camshaft 10 passes through the placement seat 4.

[0040] The above embodiments are only used to illustrate the technical solution of the utility model and are not intended to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model. The technology, shape, and structure that are not described in detail in the utility model are all well-known technologies.
