Description

Technical Field

[0001] This utility model relates to the field of dry ice cleaning technology, and in particular to a multi-angle dry ice cleaning fixture. Background Technology

[0002] After a product is formed, burrs will appear on the edges of the workpiece. These burrs affect the product's appearance and quality. The presence of burrs not only affects the product's appearance but may also adversely affect its performance and lifespan. Therefore, burr removal is essential. Existing dry ice cleaning equipment has an ice outlet pipe. By connecting nozzles of different shapes and sizes and adjusting the ice output, the cleaning effect can be changed. However, a single nozzle can only clean one location on the product at a time. If multiple locations need to be cleaned, multiple dry ice cleaning machines or robotic arms are required, resulting in a complex, costly, and inefficient deburring process.

[0003] Therefore, how to improve the efficiency of dry ice cleaning products is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a multi-angle dry ice cleaning fixture that can improve the efficiency of dry ice cleaning products and reduce the cost of cleaning products.

[0012] Preferably, the guide through hole on the first fastener or the guide through hole on the second fastener is provided with a first countersunk hole, which is used to accommodate the end of the guide post.

[0013] Preferably, the base, the first fastener, and the second fastener are all cuboid structures. The two corners of the base are provided with second countersunk holes diagonally. The first fastener and the second fastener are provided with third countersunk holes corresponding to the positions of the second countersunk holes. The second countersunk holes can be connected with the third countersunk holes to install positioning pins.

[0014] Preferably, the base is detachably connected to the first or second fastener by two fixing bolts, which are arranged diagonally.

[0018] Compared with the above-mentioned background technology, the present invention provides a multi-angle dry ice cleaning fixture, comprising: a fixing component and two bases; the fixing component includes a first fastener and a second fastener, the first fastener being able to dock with the second fastener to form a receiving cavity for fixing the product, and the product having a cleaning gap with the inner wall of the receiving cavity, and both the first fastener and the second fastener having a dry ice inlet communicating with the cleaning gap on their side walls; the two bases are respectively detachably installed on the opposite sides of the first fastener and the second fastener, and the bases have a connecting through hole communicating with the dry ice inlet in the middle, the connecting through hole being used to install an ice outlet tube.

[0019] In this embodiment, the fixing component includes two assembleable fasteners, a first fastener and a second fastener. When assembled, they form a cavity that can accommodate and fix the product to be cleaned.

[0039] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0041] The purpose of this invention is to provide a multi-angle dry ice cleaning fixture that can improve the efficiency of dry ice cleaning products and reduce the cost of cleaning products.

[0042] To achieve the above objectives, the present invention provides the following technical solution:

[0043] Please see Figures 1 to 9 This embodiment provides a multi-angle dry ice cleaning fixture, including: a fixing component and two bases 200; the fixing component includes a first fastener 110 and a second fastener 120, the first fastener 110 can be connected with the second fastener 120 to form a receiving cavity 130 for fixing product 01, and a cleaning gap 140 is left between product 01 and the inner wall of the receiving cavity 130, and the side walls of the first fastener 110 and the second fastener 120 are provided with dry ice inlets 150 communicating with the cleaning gap 140; the two bases 200 are detachably installed on the opposite sides of the first fastener 110 and the second fastener 120, and the middle of the base 200 is provided with a connecting through hole 210 communicating with the dry ice inlet 150, the connecting through hole 210 is used to install an ice outlet pipe.

[0044] In this embodiment, the fixing component includes two assembleable first fasteners 110 and second fasteners 120. Both have the same structural dimensions and can be symmetrically assembled into a single unit. After assembly, the unit forms a receiving cavity 130 that can accommodate and fix the product 01 to be cleaned. Specifically, the shape of the receiving cavity 130 matches the shape of the workpiece to be cleaned. In this embodiment, the receiving cavity 130 has a cylindrical structure; that is, both the first fastener 110 and the second fastener 120 have cylindrical grooves in their middle portions. When the two grooves are joined together, they form a complete receiving cavity 130. After the fixed components are assembled and installed, the product 01 to be cleaned will be confined to the bottom of the receiving cavity 130. However, a cleaning gap 140 is left between the product 01 and the inner wall of the receiving cavity 130. The existence of the cleaning gap 140 facilitates the entry of dry ice to clean the area around the product 01. The dry ice in the cleaning gap 140 will be introduced through the dry ice inlet 150. Specifically, on both sides of the first fastener 110 and the second fastener 120, there are dry ice inlets 150 that communicate with the receiving cavity 130, that is, they communicate with the cleaning gap 140.

[0045] Furthermore, a base 200 is installed on the outer side of both the first fastener 110 and the second fastener 120. A connecting through hole 210 for connecting the ice outlet tube is provided in the middle of the base 200. The size and cross-sectional shape of the connecting through hole 210 can be adjusted according to actual needs. In this embodiment, the connecting through hole 210 is circular and has internal threads, which facilitates connection with the external ice outlet tube. It should be noted that the connecting through hole 210 is connected to the dry ice inlet 150 of the first fastener 110 and the second fastener 120 respectively. The dry ice inlet 150 is connected to the cleaning gap 140. That is to say, the dry ice from the ice outlet tube will enter the receiving cavity 130 along the channel and perform deburring treatment on the product 01 in all directions in the cleaning gap 140.

[0046] With this setup, when product 01 needs to be cleaned, the first fastener 110 and the second fastener 120 are separated, product 01 is placed in place, the first fastener 110 and the second fastener 120 are then joined together, and dry ice is filled into the receiving cavity 130, which is the cleaning gap 140, to clean product 01. After cleaning, the first fastener 110 and the second fastener 120 are separated, and product 01 is removed. This significantly improves the efficiency of dry ice cleaning of product 01, reduces the difficulty of cleaning product 01, and improves the convenience of cleaning.

[0047] Preferably, the receiving cavity 130 includes a first chamber 131 and a second chamber 132, and the top of the first chamber 131 is provided with a snap-fit ​​portion for limiting the product 01.

[0048] Specifically, such as Figure 4 and Figure 7 As shown, in order to thoroughly clean all parts of product 01 and improve the cleaning effect, the cleaning gap 140 should not be too large. Therefore, the shape of the receiving cavity 130 should be adapted to the shape of product 01. Since product 01 in this embodiment has a stepped shaft structure, the receiving cavity 130 is provided with a first chamber 131 and a second chamber 132 with a diameter slightly larger than that of product 01. The second chamber 132 is located at the bottom, and the first chamber 131 is located at the top. At the same time, in order to prevent product 01 from falling out of the receiving cavity 130 during cleaning, an inwardly protruding snap-fit ​​part is provided on the inner wall of the top of the first chamber 131. The snap-fit ​​part will press against product 01 and effectively prevent product 01 from moving axially.

[0049] Preferably, the fixing assembly includes a first ice discharge channel 160 communicating with the first chamber 131 and a second ice discharge channel 170 communicating with the second chamber 132. The first ice discharge channel 160 and the second ice discharge channel 170 are perpendicular to each other and both communicate with the cleaning gap 140.

[0050] Understandably, the dry ice used to clean product 01 needs to be discharged. However, because the receiving cavity 130 is divided into a first chamber 131 and a second chamber 132 of different sizes to accommodate the shape of product 01, using only one channel for discharging the dry ice could easily lead to untimely discharge. Therefore, in this embodiment, the receiving cavity 130 is provided with two sets of channels communicating with the outside, namely a first ice discharge channel 160 and a second ice discharge channel 170. Figures 3 to 7As shown, the first ice discharge channel 160 is connected to the first chamber 131, and two channels are specifically provided, one on each side of the inner wall of the receiving chamber 130. The first ice discharge channel 160 extends axially along the inner wall of the first chamber 131, while the second ice discharge channel 170 is horizontally arranged and connected to the second chamber 132. The second ice discharge channel 170 is located at the bottom of the second chamber 132. With this arrangement, the dry ice in the first chamber 131 is discharged through the first ice discharge channel 160, and the dry ice in the second chamber 132 is discharged through the second ice discharge channel 170. The timely discharge of dry ice will not affect the cleaning quality of product 01.

[0051] Preferably, both the first fastener 110 and the second fastener 120 are provided with guide holes 180 in the middle, and guide posts 300 are installed in the guide holes 180. The first fastener 110 and the second fastener 120 are movably connected through the guide posts 300.

[0052] In this embodiment, to facilitate the assembly and opening of the first fastener 110 and the second fastener 120, that is, to facilitate the placement of product 01 into the receiving cavity 130, guide holes 180 are provided in the middle of both the first fastener 110 and the second fastener 120, and a guide post 300 is installed in the guide hole 180, specifically as follows: Figure 8 and Figure 9 As shown; of course, in this embodiment, the guide through hole 180 and the guide post 300 are symmetrically arranged in two sets, and the number of both can be adjusted according to actual needs. This article does not make specific limitations. With this arrangement, each time the first fastener 110 and the second fastener 120 are opened and closed, only one of them needs to be pulled, which reduces the time required for docking each time they are assembled and greatly improves the cleaning efficiency of product 01.

[0053] Preferably, the guide through hole 180 on the first fastener 110 or the guide through hole 180 on the second fastener 120 is provided with a first countersunk hole 181 at the end, the first countersunk hole 181 being used to accommodate the end of the guide post 300.

[0054] Understandably, in order to fix the guide post 300 to one of the first fastener 110 or the second fastener 120, the end of the guide post 300 in this embodiment is provided with a bolt head. However, since the base 200 is installed on the outside of both the first fastener 110 and the second fastener 120, in order to prevent the bolt head of the guide post 300 from affecting the installation of the base 200, the end of the guide through hole 180 in the first fastener 110 or the second fastener 120 is provided with a first countersunk hole 181 that can accommodate the bolt head.

[0055] Preferably, the base 200, the first fastener 110 and the second fastener 120 are all cuboid structures. The two corners of the base 200 are provided with second countersunk holes 190 diagonally. The first fastener 110 and the second fastener 120 are provided with third countersunk holes 220 corresponding to the positions of the second countersunk holes 190. The second countersunk holes 190 can be connected with the third countersunk holes 220 to install the positioning pin 400.

[0056] Specifically, such as Figure 8 and Figure 9 As shown, in this embodiment, the base 200, the first fastener 110, and the second fastener 120 are all cuboid structures. The two opposite corners of the base 200, the first fastener 110, and the second fastener 120 are respectively provided with a second countersunk hole 190 and a third countersunk hole 220. The second countersunk hole 190 and the third countersunk hole 220 can be connected after the base 200 is installed. In this embodiment, a positioning pin 400 is installed in the connected second countersunk hole 190 and third countersunk hole 220 to limit the position of the base 200 and the first fastener 110, as well as the base 200 and the second fastener 120.

[0057] Preferably, the base 200 is detachably connected to the first fastener 110 or the second fastener 120 by two fixing bolts 500, the two fixing bolts 500 being diagonally distributed.

[0058] Furthermore, in order to detachably connect the base 200 and the first fastener 110, the base 200 and the second fastener 120, in this embodiment, fixing bolts 500 are provided at the other two corners of the base 200, and the fixing bolts 500 are threaded to the first fastener 110 or the second fastener 120; in this way, with the cooperation of the positioning pin 400 and the fixing bolts 500, the base 200 can be easily connected to the first fastener 110 and the second fastener 120 respectively.

[0059] Preferably, a sealing ring 600 is installed between the base 200 and the first fastener 110 or the second fastener 120, and the sealing ring 600 is coaxial with the connecting through hole 210.

[0060] Understandably, in order to prevent dry ice leakage when it is filled from the through hole and the dry ice inlet 150, an annular sealing ring 600 is provided at the connection between the through hole and the dry ice inlet 150. Specifically, the first fastener 110 and the second fastener 120 are provided with annular grooves at corresponding positions to limit the position of the sealing ring 600 and prevent it from sliding. At the same time, the diameter of the sealing ring 600 is larger than the diameter of the through hole and the dry ice inlet 150, and the three are coaxially distributed. This arrangement can reduce dry ice leakage.

[0061] Preferably, the dry ice inlet 150 has an inverted T-shaped structure and includes a first hole 151 communicating with the first chamber 131 and a second hole 152 communicating with the second chamber 132.

[0062] Specifically, such as Figure 8 and Figure 9 As shown, the dry ice inlet 150 is an inverted T-shaped groove located on the side wall of the first fastener 110 or the second fastener 120. A first hole 151 and a second hole 152 communicating with the internal receiving cavity 130 are provided within this groove. The first hole 151 and the second hole 152 have the same and relatively small diameter, which facilitates the pressure exerted by the dry ice filling the receiving cavity 130, allowing it to clean the product 01. The arrangement of the first hole 151 and the second hole 152 ensures that the dry ice is filled into the first cavity 131 and the second cavity 132 as evenly as possible, thus preventing any leakage of the product 01. Furthermore, the number of the first hole 151 or the second hole 152 can be adjusted according to the difficulty of cleaning the product 01; no specific limitation is made here.

[0063] Preferably, the opening of the dry ice inlet 150 gradually widens on the side near the base 200.

[0064] Understandably, the end of the dry ice inlet 150 is chamfered to make the opening of the dry ice inlet 150 gradually widen, which is conducive to the smooth flow of dry ice.

[0065] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0066] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
