Description

Technical Field

[0001] This application belongs to the field of parts processing and clamping fixture technology, and specifically relates to a freezing suction cup. Background Technology

[0002] In the clamping of irregularly shaped parts, hollowed-out parts, non-metallic materials, flexible materials, and small parts, freezing suction cup equipment is generally used to fix the position before processing.

[0003] One existing technology involves a freezing suction cup with a mounting frame inside a cooling box. The surface of the mounting frame is covered with several evenly arranged thermoelectric coolers. These coolers conduct electricity to achieve cooling, freezing the water on the surface of the freezing plate and thus securing the parts to be fixed. However, the thermoelectric coolers generate a significant amount of heat during use. Although heat dissipation can be achieved by installing a heat sink inside the cooling box, the cooling effect is limited, and the generated heat still affects the freezing effect to some extent. Furthermore, adding heat dissipation structures increases the overall size of the freezing suction cup. In addition, this existing freezing suction cup also suffers from slow defrosting speed and high energy consumption. Utility Model Content

[0040] Example 1

[0041] A specific embodiment of this utility model is as follows: Figures 1 to 5 As shown, a frozen suction cup is disclosed, comprising:

[0042] Working surface layer 1;

[0043] The hot and cold layer 2, located below the working surface layer 1, is in direct contact with the lower surface of the working surface layer 1 and can transfer heat. The hot and cold layer 2 has a dual-loop structure. One loop supplies refrigerant to cool the freezing suction cup, while the other loop supplies circulating antifreeze to accelerate the thawing speed of the entire working surface layer 1 when the workpiece is thawed after processing. Specifically, the hot and cold layer 2 has a cooling channel 21 and a heating channel 22. The cooling channel 21 is configured to supply refrigerant when freezing adsorption is required to fix the working surface layer 1 to the workpiece to be fixed. The heating channel 22 is configured to supply antifreeze to accelerate the thawing of the working surface layer 1 and the workpiece to be fixed when thawing is required.

[0044] The base 4 is located below the hot and cold layer 2.

[0045] When it is necessary to freeze and fix the workpiece to the working surface layer 1, first spray a certain amount of water onto the working surface layer 1, then place the workpiece, and then supply refrigerant into the cooling channel 21. The refrigerant can freeze the working surface layer 1, quickly freezing the water on the working surface layer into ice. The strong adhesive properties of ice are used to fix the working surface layer 1 to the workpiece. After the workpiece is processed, it needs to be thawed, and the supply of refrigerant into the cooling channel 21 is stopped. Then, cutting fluid is sprayed onto the working surface layer and the workpiece, and simultaneously, thermal antifreeze is supplied into the heating channel 22. The thermal antifreeze has a high temperature and can heat the working surface layer 1, allowing it to thaw simultaneously from the upper and lower surfaces of the working surface layer and the workpiece. (Instruction manual ZSU240856CN)

[0046] To speed up the thawing process, once thawing is complete, the workpiece can be moved.

[0047] In one preferred embodiment, the refrigerant is a non-toxic and harmless refrigerant, such as liquid nitrogen, ethylene glycol, ethanol, etc., which are environmentally friendly and recyclable.

[0048] In one preferred embodiment, a heat insulation layer 3 is further provided between the hot and cold layer 2 and the base 4. By providing the heat insulation layer 3 between the working surface layer 1 and the hot and cold layer 2, heat transfer is reduced during freezing, accelerating the freezing speed. At the same time, due to the presence of the heat insulation layer 3, heat transfer is effectively avoided during processing, helping to keep the surface of the frozen suction cup at a low temperature and reducing energy consumption.

[0049] In this embodiment, the two ends of the refrigeration channel 21 are respectively provided with a refrigerant inlet 23 and a refrigerant outlet 24, and the two ends of the heating channel 22 are respectively provided with an antifreeze inlet 25 and an antifreeze outlet 26; the refrigerant inlet 23, the refrigerant outlet 24, the antifreeze inlet 25, and the antifreeze outlet 26 are provided on the side wall of the hot and cold layer 2.

[0050] The refrigerant inlet 23 is connected to a refrigerant source via a refrigerant supply pipe, and the refrigerant outlet 24 is connected to a refrigeration cycle system via a refrigerant discharge pipe. The antifreeze inlet 25 is connected to a thermal antifreeze source, and the antifreeze outlet 26 is connected to a thermal antifreeze circulation supply system.

[0051] In one optional embodiment, the hot and cold layer 2 is a cuboid structure with four vertical sidewalls. The refrigerant inlet 23, refrigerant outlet 24, antifreeze inlet 25, and antifreeze outlet 26 are located on the same vertical sidewall. The refrigerant inlet 23 and the antifreeze inlet 25 are arranged adjacent to each other and located at one edge of the vertical sidewall along its length. The refrigerant outlet 24 and the antifreeze outlet 26 are arranged adjacent to each other and located at the other edge of the vertical sidewall along its length.

[0052] Furthermore, the cooling channel 21 and the heating channel 22 have the same shape and are arranged adjacent to each other, which enables rapid and uniform defrosting. For example, both the cooling channel 21 and the heating channel 22 include multiple straight channels 27 and multiple connecting channels 28. The straight channels 27 are arranged in parallel, and adjacent straight channels 27 are connected at their ends by a connecting channel 28 perpendicular to the straight channels 27.

[0053] In one optional embodiment, the top surface of the working surface layer 1 is provided with a grid-like groove 11, the purpose and function of which are: 1. to allow the water sprayed on the working surface layer to have better fluidity and more uniform coverage, avoiding the problem of insufficient clamping force caused by the formation of local voids between some large workpieces and the working surface layer; 2. the design of the grid-like groove can increase the total surface area of ​​the working surface layer, which can both accelerate the freezing speed and improve the thawing speed; 3. the design of the grid-like groove also increases the contact area after freezing, improving the clamping strength after freezing, and the workpiece can be better clamped on the working surface layer.

[0054] In one alternative embodiment, the base 4 is made of ferrous magnetic material, enabling rapid clamping on some magnetically attached workpiece tables.

[0055] In one alternative embodiment, the working surface layer 1, the hot and cold layer 2, the heat insulation layer 3 and the base 4 are detachably connected, such as by bolts connecting adjacent layers.

[0056] Furthermore, the lower surface of the working surface layer 1 is provided with a slot, and the top surface of the hot and cold layer 2 is provided with a protrusion 29, which can be inserted into the slot.

[0057] For example, the top surface of the hot and cold layer 2 is provided with a cooling groove and a heating groove. When the working surface layer 1 is installed on the hot and cold layer 2, the top openings of the cooling groove and the heating groove can be sealed, thereby forming the cooling channel 21 and the heating channel 22.

[0058] In one alternative embodiment, the hot and cold layer 2 is a cuboid structure made of aluminum or copper, and the cooling groove and the heating groove are formed by machining, etching or injection molding.

[0059] Compared with the prior art, the freezing suction cup provided in this embodiment has the following beneficial effects:

[0060] 1. It can achieve stress-free clamping of products in machining, rapid freezing and clamping, and rapid thawing; the hot and cold layers have a dual-circuit structure. One circuit cools the freezing suction cup by supplying refrigerant, while the other circuit accelerates the thawing speed of the entire working surface layer by supplying circulating antifreeze when thawing the workpiece after machining.

[0061] 2. By setting a heat insulation layer between the working surface layer and the hot and cold layers, heat transfer is reduced during freezing, which accelerates the freezing speed. At the same time, due to the presence of the heat insulation layer, heat transfer is effectively avoided during processing, which helps to keep the surface of the frozen suction cup at a low temperature and reduces energy consumption.

[0062] 3. The base of the freezing suction cup is made of iron magnetic material, which enables quick clamping on some magnetic workpiece tables.

[0063] 4. The refrigerant can be non-toxic and harmless, such as liquid nitrogen, which is environmentally friendly and recyclable.

It should be understood that the above description is only a specific embodiment of this application and is not intended to limit the scope of protection of this application.
