Description

Technical Field

[0001] The utility model relates to the technical field of vacuum furnace charge racks, in particular to a vacuum furnace charge rack with up and down adjustment functions. Background Art

[0002] A vacuum furnace uses a vacuum system to discharge some of the materials in the furnace cavity, making the pressure in the furnace cavity less than a standard atmospheric pressure, thereby achieving a vacuum state in the furnace cavity.

[0003] At present, most vacuum furnaces need to be used in conjunction with vacuum furnace racks when in use, and the molds to be processed are placed on the racks for processing. However, when stacking, most vacuum furnace racks generally adjust the distance between several layers of rack plates by installing a number of sleeves on the four sleeve rods set on the rack plates, so that the rack plates can be placed in multiple layers. However, since the sleeves are individually manufactured, their heights are fixed and cannot be adjusted. Even if the height can be adjusted by stacking multiple sleeves, the adjusted height is increased by multiples of the fixed value, and the height cannot be fine-tuned. The molds placed on the rack plates are of different heights, and the existing height adjustment method cannot accurately adapt to the heights of different molds, which often results in insufficient utilization of the internal space of the vacuum furnace and waste of space between multiple layers of racks. Therefore, it is necessary to design a vacuum furnace rack that can fine-tune the height and better adapt to molds of different heights to solve the above problems. Utility Model Content

[0020] The following diagrams illustrate various embodiments of the present invention. For clarity, many physical details will be included in the following description. However, it should be understood that these physical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these physical details are not essential. Furthermore, to simplify the illustrations, some commonly used structures and components are depicted in a simplified schematic manner.

[0021] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0022] In the description of this technology, it should also be noted that, unless otherwise specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this technology based on the specific circumstances.

[0023] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0024] See also Figure 1-3The utility model includes a material rack base plate 01 and a material rack stack 011. Limiting components are provided at the four corners of the top of the material rack base plate 01. The material rack stack 011 is arranged between the limiting components. An adjusting component is provided on the outer surface of the limiting component. The adjusting component is used to adjust the height of the material rack stack 011; measuring components are provided on both sides of the material rack base plate 01, and the measuring components are used to measure the height after adjustment by the adjusting component.

[0025] See also Figure 2 In this embodiment, in order to better connect the rack stack 011 with the threaded rod 021, the limiting assembly includes mounting holes 02 and threaded rods 021. The mounting holes 02 are opened at the four corners of the top of the rack base plate 01. The mounting holes 02 do not penetrate the rack base plate 01. The top surfaces of the rack base plate 01 and the rack stack 011 are evenly penetrated with ventilation holes 012. The ventilation holes 012 are hexagonal.

[0026] There are several threaded rods 021 and they are respectively arranged in several mounting holes 02. Docking holes are opened at the four corners of the top of the material rack stack 011 corresponding to the threaded rods 021. The diameter of the docking hole is larger than the diameter of the threaded rod 021. Several threaded rods 021 are perpendicular to the bottom of the inner cavity of the mounting hole 02. Preferably, there are four mounting holes 02 and docking holes.

[0027] When it is necessary to dock the rack stack 011 with the threaded rod 021, first align the docking holes at the four corners of the rack stack 011 with the four threaded rods 021 and snap them in, so that several layers are formed between the rack stack 011 and the rack base plate 01, which makes it convenient for the staff to place the molds separately and prevent deformation caused by stacking the molds.

[0028] See also Figure 1 It should be noted that in order to better adjust and limit the height of the material rack stack 011, the adjustment component includes an adjusting nut 03 and a limit spring 031. There are several adjusting nuts 03 and they are all threadedly connected to the outer surface of the threaded rod 021. The outer diameter of the adjusting nut 03 is larger than the diameter of the mounting hole 02. The limit spring 031 is sleeved on the outer surface of the threaded rod 021 below the adjusting nut 03, and the bottom end of the limit spring 031 is inserted into the inner cavity of the mounting hole 02.

[0029] When the cam 03 is in the closed position, the cam 03 is tightened and the screw 03 is tightened, so that the cam 03 is tightened and the screw 03 is tightened.

[0030] See also Figure 1 and Figure 3 Specifically, in order to enable the staff to more accurately adjust the four adjustment threads to the same height when turning the adjustment nut 03, the measuring assembly includes a turntable 04, a ruler 041, an inner rod 05 and a limit block 051. There are two groups of turntables 04, and each group has two turntables. Each group of turntables 04 is respectively set at positions corresponding to the center of the threaded rod 021 on both sides of the material rack base plate 01. The turntable 04 and the material rack base plate 01 are connected and fixed by a damping bearing;

[0031] The scales 041 are arranged on opposite sides of each set of turntables 04 and are distributed up and down. The outer surfaces of the scales 041 are all provided with scale lines. Permanent magnets that attract each other are arranged between each set of scales 041.

[0032] Each set of scales 041 has a movable cavity at one end away from the turntable 04, and the inner rod 05 is movably inserted into the movable cavity. The limit block 051 is set at the end of the inner rod 05 away from the turntable 04, and the outer surface of the inner rod 05 is also provided with scale lines.

[0033] When the staff needs to adjust the height of the four adjusting nuts 03, first turn the scales 041 on both sides of the material rack base plate 01 upwards through the turntable 04, so that the scales 041 are perpendicular to the material rack base plate 01, and the four adjusting nuts 03 can be adjusted to the same height value by referring to the scale lines on the scales 041. When the height of the scale 041 is not enough, the inner rod 05 can be pulled out through the limit block 051, and the height reference can be continued through the scale lines on the inner rod 05. After use, it will be installed in the order of folding from bottom to top, and fixed by the permanent magnet between the two scales 041, so that the scale 041 is placed more firmly.

[0034] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
