Description

Technical Field

[0001] The utility model relates to a heat treatment transfer vehicle for an automotive air-conditioning compressor piston. Background Art

[0002] Heat treatment is a metal hot working process that heats, holds, and cools metal materials in a certain medium to control their properties by changing the metallographic structure on the surface or inside of the materials. Among them, the pistons of automotive air-conditioning compressors need to be heat-treated in a heat treatment furnace. When heat-treating the pistons, generally, the pistons are placed on a stacking rack, and then the stacking rack is pushed into the heat treatment furnace. In view of this, a stacking rack for piston heat treatment is disclosed in the patent document with the application number 201921934068.1. The height of the stacking rack in the above prior art cannot be adjusted, and it is necessary to replace the stacking rack with a corresponding height for the piston when heat-treating different pistons. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the above deficiencies existing in the prior art, and to provide a heat treatment transfer vehicle for an automotive air-conditioning compressor piston with a reasonable structural design.

[0004] The technical solution adopted by the utility model to solve the above problems is: the heat treatment transfer vehicle for an automotive air-conditioning compressor piston includes a bottom frame, a plurality of middle frames, and a top frame. Its structural characteristics are as follows: the bottom frame and the middle frames, between adjacent middle frames, and between the middle frame and the top frame are all connected by an adjusting mechanism; the adjusting mechanism includes a limit ring, an adjusting sleeve, a lifting rod, a lifting ring, a lifting block, a lifting groove, and an adjusting nut. Adjusting sleeves are provided at the tops of the bottom frame and the middle frames, limit rings are provided at the bottoms of the middle frames and the top frame, the lifting ring is sleeved outside the adjusting sleeve, the lifting rod is installed in the adjusting sleeve, the outer wall of the lifting rod is connected to the inner wall of the lifting ring through the lifting block, the lifting groove is provided on the side wall of the adjusting sleeve, the lifting block is located in the lifting groove, and the adjusting nut is threadedly connected to the adjusting sleeve.

[0005] Furthermore, wheels and a towing frame are provided on the bottom frame.

[0006] Furthermore, lifting rings are provided on the bottom frame, the middle frames, and the top frame.

[0007] Compared with the prior art, the utility model has the following advantages: when the heat treatment transfer vehicle for the piston of the automotive air-conditioning compressor performs heat treatment on pistons of different heights, by turning the adjusting nut forward, the adjusting nut can push the lifting ring upward, and then the height of the lifting rod exposed outside the adjusting sleeve can be adjusted. When the adjusting nut is turned backward, the lifting rod can fall under the action of gravity, so as to place and transfer pistons of different heights. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following further describes the utility model in detail with reference to the drawings and through embodiments. The following embodiments are explanations of the utility model and the utility model is not limited to the following embodiments.

[0015] Embodiment

[0016] Refer to Figures 1 to 4As shown, it should be noted that the structures, proportions, sizes, etc. shown in the drawings of this specification are only used to match the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the implementation conditions of this utility model. Therefore, they do not have technical essence. Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the effects that this utility model can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in this utility model. At the same time, if terms such as "upper", "lower", "left", "right", "middle", and "one" are cited in this specification, they are only for the convenience of clear narration and are not used to limit the implementation scope of this utility model. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the implementable scope of this utility model.

[0017] The heat treatment transfer vehicle for the piston of the automotive air conditioner compressor in this embodiment includes a bottom frame 1, a plurality of middle frames 2, and a top frame 3. The bottom frame 1 is connected to the middle frame 2, between adjacent middle frames 2, and between the middle frame 2 and the top frame 3 through adjusting mechanisms 4; wheels 5 and a towing frame 6 are arranged on the bottom frame 1, and lifting rings 7 are arranged on the bottom frame 1, the middle frames 2, and the top frame 3.

[0018] The adjusting mechanism 4 in this embodiment includes a limiting ring 41, an adjusting sleeve 42, a lifting rod 43, a lifting ring 44, a lifting block 45, a lifting groove 46, and an adjusting nut 47. Adjusting sleeves 42 are arranged at the tops of the bottom frame 1 and the middle frame 2, limiting rings 41 are arranged at the bottoms of the middle frame 2 and the top frame 3, the lifting ring 44 is sleeved outside the adjusting sleeve 42, the lifting rod 43 is installed inside the adjusting sleeve 42, the outer wall of the lifting rod 43 is connected to the inner wall of the lifting ring 44 through the lifting block 45, the lifting groove 46 is arranged on the side wall of the adjusting sleeve 42, the lifting block 45 is located in the lifting groove 46, and the adjusting nut 47 is threadedly connected to the adjusting sleeve 42.

[0019] Specifically, when the heat treatment transfer vehicle for the piston of the automotive air conditioner compressor performs heat treatment on pistons of different heights, the adjusting nut 47 can be screwed forward to make the adjusting nut 47 push the lifting ring 44 upward. When the adjusting nut 47 is screwed backward, the lifting rod 43 can fall by itself under the action of its own gravity. Furthermore, the height adjustment between adjacent frames can be realized. During adjustment, different height adjustments can be made between the bottom frame 1 and the middle frame 2, between adjacent middle frames 2, and between the middle frame 2 and the top frame 3 respectively, so as to place pistons of different heights and perform heat treatment on pistons of different specifications in the same heat treatment furnace.
