Description

Technical Field

[0001] This invention relates to the field of machining, and more specifically to a clamp. Background Technology

[0002] The inventors learned that the processing of products such as liquid reservoirs and gas-liquid separators requires fixing with specially designed fixtures before further surface treatment. Since these products require anti-corrosion and anti-rust treatments, surface treatment often involves spraying or painting. This surface treatment process requires the fixture to expose as much of its surface as possible for painting. Because different surface treatment processes have different requirements for the fixtures, if the liquid reservoirs and gas-liquid separators are not surface treated with spraying or painting, additional specialized fixtures need to be designed.

[0014] The embodiments are described below with reference to the accompanying drawings.

[0015] Please refer to Figures 1-4 As shown, a clamp 100 includes a bracket 1 and at least one clamping component 2, which is fixedly disposed with the bracket 1. The clamping component 2 includes a top section 21, a middle section 22, and a bottom section 23. The top section 21 is bent relative to the middle section 22, and the bottom section 23 is bent relative to the middle section 22. Alternatively, the bracket can only include the top and bottom sections, with the top section fixed to the bracket and the bottom section fixed to the bracket, thus achieving the fixation of the clamping component to the bracket.

[0016] The top segment 21 has a first limiting portion 211, and the bottom segment 23 has a second limiting portion 231. The second limiting portion 231 faces the top segment 21. Along the axial direction of the clamping member 2, at least a portion of the first limiting portion 211 is disposed opposite to the second limiting portion 231 and / or the center line of the first limiting portion 211 is disposed opposite to the second limiting portion 231, so that the part can be limited between the first limiting portion and the second limiting portion.

[0017] in, Figure 1 In the Y direction, which is the axial direction of the clamping component 2, when a part is assembled in the clamp 100, the first limiting part 211 and the second limiting part 231 can be used to limit the part. In this embodiment, in the axial direction of the clamping component, the center line of the first limiting part is arranged opposite to the second limiting part, so that the first limiting part and the second limiting part can limit the part. Of course, depending on the actual situation, at least a part of the first limiting part can be arranged opposite to the second limiting part.

[0018] In this embodiment, the middle section 22 is fixedly disposed with the bracket 1, and the top section 21 has a cover 212 and a protrusion 213. The protrusion 213 is integrally disposed with the middle section 22, and the protrusion 213 is bent relative to the middle section 22. The cover 212 and the protrusion 213 are fixedly disposed.

[0019] The cover includes a bottom wall and / or a side wall, with a first limiting portion located on the bottom wall or the side wall. In this embodiment, the cover 212 includes a side wall 2122, and the first limiting portion 211 is located on the side wall 2122. This arrangement allows the part to be partially placed inside the cover 212, which can relatively enhance the stability of the part during installation. Of course, depending on the actual situation, the cover can also include a bottom wall, with the first limiting portion located on the bottom wall, the bottom wall facing the protrusion, and the bottom wall fixed to the protrusion, which can also limit the part between the cover and the second limiting portion; or, the cover includes a bottom wall and a side wall, with the first limiting portion located on the bottom wall or the side wall, the bottom wall facing the protrusion, the bottom wall connected to the side wall, and the bottom wall fixed to the protrusion, which can also limit the part between the cover and the second limiting portion; or, the part can also be limited between the protrusion and the second limiting portion.

[0020] In this embodiment, the cover 212 has a sidewall 2122, which is not parallel to the axial direction of the clamping member 2. The sidewall 2122 has a first end 2122' and a second end 2122"". The distance between the first end 2122' and the bottom segment 23 is smaller than the distance between the second end 2122" and the bottom segment 23. The sidewall 2122 radially contracts from the first end 2122' to the second end 2122". Radial refers to the diameter direction of the first end 2122' and the second end 2122".

[0021] The first limiting part 211 is located on the side wall 2122 of the cover 212, and the first limiting part 211 is located between the first end 2122' and the second end 2122". This arrangement can relatively enhance the stability of the part being clamped between the cover 212 and the second limiting part 231.

[0022] The second end 2122” is annular, and the protrusion 213 is welded and fixed to the second end 2122”. The cover 212 has a first opening 2123 and a second opening 2124. The first opening 2123 is located at the first end 2122’, and the second opening 2124 is located at the second end 2122”. The equivalent diameter of the second opening 2124 is smaller than the equivalent diameter of the first opening 2123, and the width of the protrusion 213 is smaller than the equivalent diameter of the second opening 2124, so that the solution can enter the cover 212 through the second opening 2124, thereby allowing the upper part of the part to react with the solution.

[0023] Of course, depending on the actual situation, the sidewall can be provided with one or more openings, and one or more openings are located between the first limiting part and the second end, so that the solution can enter the body through the openings on the sidewall, react with the upper part of the part, and increase the coating area.

[0024] Please refer to Figure 8 As shown, in the second embodiment, the cover 212' has a bottom wall 2121', which is welded and fixed to the protrusion 213. A first limiting part 211' is located on the bottom wall 2121', which has one or more orifices, allowing the solution to react with the upper part of the part and increase the coating area of ​​the part. The cover 212' has a side wall 2122, the radial dimension of which is greater than or equal to that of the bottom wall 2121', allowing the part to be partially placed inside the cover 212', and the upper end of the part to be limited by the cover 212'.

[0025] In this embodiment, the bottom segment 23 has at least one protrusion 232 extending along the width direction of the bottom segment 23. The projection of the protrusion 232 onto the top segment 21 along the axial direction of the clamping member 2 is located within the region of the top segment 21. The second limiting portion 231 is located on the protrusion 232, such that the contact area between the lower part of the part and the second limiting portion 231 is as small as possible, thereby relatively increasing the contact area between the part and the solution. In this invention, the region within the cover 212 includes the case where the middle part of the cover 212 is empty. The width direction of the bottom segment 23 is the direction with the smaller side length of the bottom segment 23.

[0026] In this embodiment, the bottom segment 23 includes at least a first protrusion 2321, a second protrusion 2322, and a recess 2323. The recess 2323 is located between the first protrusion 2321 and the second protrusion 2322. The first protrusion 2321 and the second protrusion 2322 extend along the width direction of the bottom segment 23, and the recess 2323 also extends along the width direction of the bottom segment 23. The projections of the first protrusion 2321 and the second protrusion 2322 onto the top segment 21 along the axial direction of the clamping member 2 are located within the area of ​​the cover 212, and the projection of the recess 2323 onto the top segment 21 along the axial direction of the clamping member 2 is also located within the area of ​​the cover 212. This ensures that the bottom of the part contacts the first protrusion 2321 and the second protrusion 2322, minimizing the contact area between the part and the bottom segment 23 and maximizing the contact area between the bottom of the part and the solution, thereby relatively increasing the coating area on the surface of the part.

[0027] Please refer to Figures 4-5As shown, in this embodiment, a portion of the second limiting part 231 is located at the first protrusion 2321, and a portion of the second limiting part 231 is located at the second protrusion 2322. This arrangement relatively reduces the contact area between the part and the bottom section 23, maximizing the contact area between the bottom of the part and the solution, thus relatively increasing the coating area on the part surface. Alternatively, depending on the actual situation, a portion of the second limiting part 231' can be located between the first protrusion 2321' and the recess 2323, and a portion of the second limiting part 231' can be located between the second protrusion 2322' and the recess 2323, with the center line of the recess 2323 coinciding with the center line of the cover 212. In this case, the contact area between the part and the bottom section is even smaller, further increasing the coating area on the part surface. Of course, the bottom section can also include three or more protrusions and two or more recesses.

[0028] Please refer to Figures 6-7 As shown, the thickness of the middle section 22 is w1, and the thickness of the bottom section 23 is w2, where 10mm≤w1≤40mm and 10mm≤w2≤40mm. Within this range, the stability of the part clamping can be enhanced. The width of the middle section 22 is t1, and the width of the bottom section 23 is t2, where 1mm≤t1≤1.5mm and 1mm≤t2≤1.5mm. Within this range, the load-bearing capacity and springback requirements of the bottom section can be met, ensuring that the bottom section is strong enough to support the weight of the parts while facilitating the clamping and installation of the parts.

[0029] The clamping component 2 is made of titanium, or the clamping component 2 is made of steel and the surface of the clamping component 2 is plated with titanium. This can meet the requirements of the clamping component for corrosion resistance, as well as the requirements of the clamping component for strength and resilience.

[0030] The bracket 1 includes a first plate 11, which includes a mounting part 111 and a hook part 112. The mounting part 111 and the hook part 112 are integrally formed. The middle section 22 is fixed to the mounting part 111, and the hook part 112 extends out of the clamping member 2.

[0031] The bracket 1 includes a first plate 11, a second plate 12, and at least two third plates 13. One end of the third plate 13 is fixed to the first plate 11, and the other end of the third plate 13 is fixed to the second plate 12. The at least two third plates 13 are spaced apart. There are multiple clamping components 2, and the middle section 22 of each clamping component 2 is fixed to at least two third plates 13.

[0032] Each of the two adjacent third plates 13 includes at least one through hole 131, the middle section 22 includes at least two through holes 221, and the clamp 100 also includes at least two screws 3, which pass through the through holes 131 and the through holes 221, thereby fixing the clamping component 2 to the bracket 1. Of course, depending on the actual situation, the middle section 22 and the third plate 13 can also be fixed by welding, which can also achieve the fixation of the clamping component 2 to the bracket 1. Of course, the hook portion 112 can be provided on the first plate 11, the second plate 12, or the third plate 13.

[0033] Although this specification has described the present invention in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to the present invention, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
