Description

Technical Field

[0001] The present application relates to the technical field of aluminum material clamps, and in particular to a clamp and a clamping device. Background Art

[0002] Aluminum has the advantages of light weight, strong toughness, good electrical and thermal conductivity, etc. It is widely used in industries such as construction, aviation, automobiles, photovoltaic power generation and electronic equipment. However, the chemical properties of aluminum are relatively active and it is easily corroded when exposed to the air for a long time. Therefore, aluminum needs to be anodized to form a dense oxide film on the surface of the aluminum to significantly improve the corrosion resistance and wear resistance of the aluminum and extend the service life of the aluminum. In the process of anodizing, the aluminum needs to be clamped by a clamping device and placed in an oxidation tank for anodizing. However, the number of aluminum pieces that can be clamped by the clamping device at a time is small, resulting in low work efficiency. Summary of the invention

[0052] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0053] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0054] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0055] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0056] Aluminum has the advantages of light weight, strong toughness, good electrical and thermal conductivity, etc. It is widely used in industries such as construction, aviation, automobiles, photovoltaic power generation and electronic equipment. However, due to the active chemical properties of aluminum, it is easy to corrode when exposed to the air for a long time. Therefore, the aluminum needs to be anodized to form a dense oxide film on the surface of the aluminum, which can significantly improve the corrosion resistance and wear resistance of the aluminum and extend the service life of the aluminum. When performing anodizing, it is necessary to use a clamping device to clamp the aluminum and drive the aluminum to move into the electrolyte for reaction. However, the clamping device in the related art can clamp a small number of aluminum sheets at a time, resulting in low working efficiency of the clamping device.

[0057] To solve the above technical problems, Figure 1 and Figure 2 As shown, the present application provides a clamp 12 and a clamping device 1 including the clamp 12. The clamping device 1 also includes an oxidized beam 11, and the clamp 12 is installed on the oxidized beam 11. The clamp 12 is used to clamp a workpiece 2 to be clamped, and the oxidized beam 11 can drive the clamp 12 to move, thereby driving the workpiece 2 to be clamped to move to a preset position.

[0058] Among them, Figure 3 and Figure 4As shown, the clamp 12 may include a base 121 and three clamping parts 122 disposed on the base 121, the three clamping parts 122 are distributed along the length direction X of the clamp 12, or two of the three clamping parts 122 are distributed along the length direction X of the clamp 12, and the other clamping part 122 and the other two clamping parts 122 are distributed along the width direction Y of the clamp 12.

[0059] like Figure 2 and Figure 4 In the illustrated embodiment, the three clamping portions 122 on the clamp 12 are distributed along the length direction X of the clamp 12. In this embodiment, by providing three clamping portions 122 on the clamp 12, the clamp 12 can clamp three workpieces to be clamped at a time. At the same time, when a fixed number of clamps 12 can be placed on the oxidation beam 11, the number of workpieces to be clamped that can be clamped by a single clamp 12 at a time is increased, thereby significantly increasing the single clamping amount of the clamping device 1 as a whole, thereby greatly improving the working efficiency of the clamping device 1.

[0060] like Figure 1 and Figure 3 In the illustrated embodiment, two of the three clamping portions 122 are distributed along the length direction X of the clamp 12, and the other clamping portion 122 and the other two clamping portions 122 are distributed along the width direction Y of the clamp 12. In this embodiment, three clamping portions 122 are provided on the clamp 12, so that the clamp 12 can clamp three workpieces 2 to be clamped at a time. At the same time, by distributing a part of the clamping portions 122 and another part of the clamping portions 122 along the width direction Y of the clamp, the volume of a single clamp 12 along the length direction X of the clamp can be reduced, so that more clamps 12 can be arranged when the length of the oxidation beam 11 is constant, thereby further improving the single clamping amount of the clamping device 1 as a whole, thereby significantly improving the working efficiency of the clamping device 1.

[0061] Among them, the length direction X of the clamp 12 , the width direction Y of the clamp 12 , and the height direction Z of the clamp 12 in the embodiment of the present application can be defined as directions when the clamp 12 is installed on the oxidized beam 11 .

[0062] In the embodiment of the present application, there is no special limitation on the specific form of the workpiece 2 to be clamped. For the convenience of description, the following description takes the workpiece 2 to be clamped as an aluminum material as an example.

[0063] In the above embodiment, Figures 3 to 6 As shown, the clamping portion 122 may include a fixed clamp 122a and a movable clamp 122b, wherein the fixed clamp 122a is fixedly connected to the base 121, and the movable clamp 122b is movably connected to the base 121. The clamping portion 122 may also include an operating portion 126, which is used to drive the movable clamp 122b to move toward or away from the fixed clamp 122a.

[0064] In this embodiment, by providing a fixed clamp 122a and a movable clamp 122b, it is convenient to control the clamping or separation of the aluminum material by the clamping portion 122. The clamping portion 122 may also be provided with an operating portion 126. When the operating portion 126 drives the movable clamp 122b to move toward the fixed clamp 122a, the clamping portion 122 is in a clamping state, and can clamp the aluminum material, so that the oxidized beam can drive the aluminum material to move through the clamp 12. After the aluminum material is anodized, the operating portion 126 can drive the movable clamp 122b to move away from the fixed clamp 122a, so that the clamping portion 122 is in a separated state, canceling the clamping of the aluminum material, so that the aluminum material can be removed for subsequent use.

[0065] Among them, the fixing clamp 122a can be made of copper alloy, specifically copper T1 alloy, so that the fixing clamp 122a is made of corrosion-resistant and highly conductive copper alloy material, which improves the oxidation resistance and corrosion resistance of the fixing clamp 122a, extends the service life of the fixing clamp 122a, and can also meet the use requirements under conditions of large current values, and can improve the conductive effect of the fixing clamp 122a to improve the oxidation effect of aluminum, thereby improving product quality.

[0066] In the above embodiments, Figure 3 and Figure 4 As shown, the clamping portion 122 may be provided with side plates 127 on both sides along the length direction X of the clamp 12 , the side plates 127 are fixedly connected to the base 121 , and the operating portion 126 may be rotatably connected to the side plates 127 via a rotating shaft.

[0067] In this embodiment, by providing side plates 127 at both ends of the clamping portion 122, the operating portion 126 can be rotatably connected to the side plates 127 via a rotating shaft, so that the operating portion 126 can rotate around the rotating shaft toward or away from the base 121. When the operating portion 126 rotates away from the base 121, the operating portion 126 can drive the movable clamp 122b away from the fixed clamp 122a, so that the clamping portion 122 is in a separated state. When the operating portion 126 rotates toward the base 121, the operating portion 126 can drive the movable clamp 122b to move toward the fixed clamp 122a, so that the clamping portion 126 is in a clamped state.

[0068] The side plate 127 can be made of titanium steel, which has good corrosion resistance. When the clamping portion 122 clamps the aluminum material and puts it into the electrolyte, part of the side plate 127 structure can be simultaneously extended into the electrolyte to ensure that the entire structure of the aluminum material is immersed in the electrolyte, thereby avoiding the phenomenon that part of the aluminum material structure is not oxidized. Titanium steel also has good physical stability, thereby ensuring that the side plate 127 does not deform during long-term use, thereby extending the service life of the side plate 127.

[0069] In a specific embodiment, Figures 3 to 6 As shown, the clamp 12 may further include at least one elastic member 129 , and two ends of the elastic member 129 are respectively connected to the base 121 and the operating portion 126 .

[0070] In this embodiment, when the operating part 126 is driven to rotate around the rotation axis away from the base 121, the clamping part 122 is switched to a separated state, and the elastic member 129 is stretched. When the operating part 126 is stopped, the operating part 126 can automatically move around the rotation axis toward the base 121 under the action of the elastic force of the elastic member 129, so that the clamping part 122 is automatically switched to a clamped state. By providing at least one elastic member 129, the clamping part 122 can be automatically switched to a clamped state under the action of the elastic force of the elastic member 129, which can simplify the operation steps. At the same time, the provision of the elastic member 129 in this embodiment also has the advantages of simple structure and easy implementation.

[0071] Among them, Figures 3 to 6 As shown, when the clamp 12 in the embodiment of the present application includes three clamping parts 122, two elastic members 129 can be provided. While meeting the use requirements, compared with the solution in the related art in which one clamping part 122 corresponds to one elastic member 129, the solution provided in the embodiment of the present application can also reduce the number of elastic members 129 set and reduce costs.

[0072] In a specific embodiment, Figure 3 and Figure 5 As shown, the three clamping portions 122 may be a first clamping portion 123, a second clamping portion 124 and a third clamping portion 125. The first clamping portion 123 and the second clamping portion 124 may be distributed along the length direction X of the clamp 12, the third clamping portion 125 may be located below the first clamping portion 123 and the second clamping portion 124 along the width direction Y of the clamp 12, and the third clamping portion 125 is located between the first clamping portion 123 and the second clamping portion 124 along the length direction X of the clamp 12.

[0073] In this embodiment, the first clamping portion 123, the second clamping portion 124 and the third clamping portion 125 are staggered and distributed in a triangular shape. While increasing the number of clamping portions 122 of the clamp 12 to increase the number of clamped aluminum materials, the structural stability of the clamp 12 can also be improved, thereby improving the safety of the clamp 12 during operation.

[0074] In the above embodiment, the operating portion 126 may include a first pull rod 126a, a second pull rod 126b and a third pull rod 126c respectively connected to the movable clamp 122b of the first clamping portion 123, the second clamping portion 124 and the third clamping portion 125, and the first pull rod 126a is fixedly connected to the second pull rod 126b. The operating portion 126 may also include a first connecting rod 126d, and the third pull rod 126c is connected to the first pull rod 126a and the second pull rod 126b through the first connecting rod 126d.

[0075] In this embodiment, by providing a first pull rod 126a, a second pull rod 126b and a third pull rod 126c connected to the movable clamp 122b, the switching of the three clamping parts 122 states can be controlled by pulling the first pull rod 126a, the second pull rod 126b and the third pull rod 126c, which can improve the convenience and consistency of operation of the clamp 12. Specifically, the first pull rod 126a and the second pull rod 126b are fixedly connected, and the third pull rod 126c is fixedly connected to the first pull rod 126a and the second pull rod 126b through the first connecting rod 126d, so that the fixed connection between the first pull rod 126a, the second pull rod 126b and the third pull rod 126d can be achieved. Therefore, when the first pull rod 126a and / or the second pull rod 126b are driven to rotate, the three pull rods can be driven to rotate synchronously, and the rotation direction is consistent, so that the working states of the three clamping parts 122 can be switched synchronously, improving the consistency between the three clamping parts 122 of the clamp 12 and facilitating the control of the clamp 12.

[0076] In another specific embodiment, Figure 4 and Figure 6 As shown, the three clamping parts 122 may be a first clamping part 123 , a second clamping part 124 and a third clamping part 125 , and the first clamping part 123 , the second clamping part 124 and the third clamping part 125 may be distributed along the length direction X of the clamp.

[0077] In this embodiment, the first clamping portion 123, the second clamping portion 124 and the third clamping portion 125 are distributed along the length direction X of the clamp. While increasing the number of clamping portions 122 of the clamp 12 to increase the number of clamped aluminum materials, the structure of the clamp 12 can be simplified to reduce costs and assembly difficulty.

[0078] In the above embodiment, the operating portion 126 may include a first pull rod 126a, a second pull rod 126b and a third pull rod 126c respectively connected to the movable clamp 122b of the first clamping portion 123, the second clamping portion 124 and the third clamping portion 125. The operating portion 126 may also include a second connecting rod 126e, and the first pull rod 126a, the second pull rod 126b and the third pull rod 126c may be fixedly connected by the second connecting rod 126e.

[0079] In this embodiment, by providing the first pull rod 126a, the second pull rod 126b and the third pull rod 126c connected to the movable clamp 122b, the switching of the states of the three clamping parts 122 can be controlled by pulling the first pull rod 126a, the second pull rod 126b and the third pull rod 126c, which can improve the convenience and consistency of operation of the clamp 12. At the same time, by providing the second connecting rod 126e to achieve the fixed connection of the first pull rod 126a, the second pull rod 126b and the third pull rod 126c, when the second connecting rod 126e is driven to rotate, the rotation of the above three pull rods can be achieved, so that the working states of the three clamping parts 122 can be switched synchronously, the consistency between the three clamping parts 122 of the clamp 12 is improved, and the operation of the clamp 12 is convenient.

[0080] In the above embodiment, Figure 4 and Figure 6 As shown, an extension portion 126 f may also be provided at the end of the second connecting rod 126 e , and the extension portion 126 f extends away from the clamping portion 122 .

[0081] In this embodiment, by providing the extension portion 126f, the second connecting rod 126e can be controlled by the extension portion 126f to drive the movable clamp 122b of the clamping portion 122 to move away from the fixed clamp 122a. At the same time, the extension portion 126f is provided at the end of the second connecting rod 126e, and the extension portion 126f is extended away from the clamping portion 122, so that the extension portion 126f can be controlled to improve the convenience of operation.

[0082] In a specific embodiment, Figure 1 and Figure 8 As shown, a first mounting portion 111 may be provided on one side of the oxidation beam 11. When the clamp 12 is as shown in FIG. Figure 3 and Figure 5 In the structure shown in , a plurality of clamps 12 may be provided on the first mounting portion 111 .

[0083] In another specific embodiment, Figure 2 and Figure 7 As shown, the oxidized beam 11 may have a first mounting portion 111 and a second mounting portion 112 that are disposed opposite to each other along the width direction Y of the clamp 12. Figure 4 and Figure 6 In the structure shown in , the first mounting portion 111 and the second mounting portion 112 are both mounted with a plurality of clamps 12. Along the width direction Y of the clamps 12, the clamping portions of the clamps 12 on the first mounting portion 111 and the clamping portions of the clamps 12 on the second mounting portion 112 can be arranged opposite to each other.

[0084] In the present embodiment, the oxidized beam 11 has a first mounting portion 111 and a second mounting portion 112 which are relatively arranged along the width direction Y of the clamp 12, and a plurality of clamps 12 are installed on the first mounting portion 111 and the second mounting portion 112. Compared with the related art in which the clamp 12 can only be arranged on one side of the oxidized beam 11, more clamps 12 can be arranged on the oxidized beam 11 of the clamping device 1 in the embodiment of the present application, thereby further increasing the amount of aluminum materials clamped by the clamping device 1 at a single time, and significantly improving the working efficiency of the clamping device 1.

[0085] At the same time, the three clamping parts on the clamp 12 are distributed along the length direction X of the clamp 12, and the operating part includes an extension part 126f extending away from the clamping part. Therefore, along the width direction Y of the clamp 12, when the clamping part of the clamp 12 on the first mounting part 111 and the clamping part of the clamp 12 on the second mounting part 112 are arranged relatively, the extension part 126f of the clamp 12 on the first mounting part 111 and the extension part 126f of the clamp 12 on the second mounting part 112 can be staggered with each other and are both located between two adjacent clamps 122 along the length direction X of the clamp 12, avoiding interference between the extension parts 126f, thereby ensuring that the clamps on the first mounting part and the second mounting part can both work normally.

[0086] Among them, the clamping device 1 in the above embodiment can be used in conjunction with a double-sided flip frame (not shown in the figure). After the clamp 12 on the first mounting part 111 clamps the aluminum material, the flip frame can rotate the oxidized beam 11 180 degrees, so that the clamp 12 on the second mounting part 112 can clamp the aluminum material, thereby enabling the oxidized beam 11 to clamp the aluminum material on both sides of the width direction Y of the clamp 12.

[0087] In the above embodiments, Figure 2 , Figure 4 and Figure 7 As shown, a limiting portion 113 can be provided on the first mounting portion 111 and the second mounting portion 112, and a limiting matching portion 130 can be provided on the clamp 12. The limiting portion 113 and the limiting matching portion 130 are snap-fitted together, and the contact surface between the limiting portion 113 and the limiting matching portion 130 is arc-shaped.

[0088] In this embodiment, by providing a limiting portion 113 and a limiting matching portion 130 that can be snap-fitted, the clamp 12 can be detachably connected to the first mounting portion 111 and the second mounting portion 112, and the contact surface between the limiting portion 113 and the limiting matching portion 130 is arc-shaped, so that after the limiting portion 113 and the limiting matching portion 130 are snap-fitted, the limiting portion 113 and the limiting matching portion 130 are not completely fixed, thereby allowing relative movement between the clamp 12 and the first mounting portion 111 and the second mounting portion 112.

[0089] Specifically, the limiting portion 113 may be a U-shaped slot, and a through hole is provided in the middle for avoiding the base structure. The limiting matching portion 130 may be a circular ring provided on both sides of the base along the length direction X of the clamp 12. When the limiting portion 113 is engaged with the limiting matching portion 130, the circular rings on both sides are engaged in the U-shaped slot, and the base structure in the middle of the circular ring extends through the through hole, and fixes the clamp 12 on the oxidation beam 11 under the action of gravity. At the same time, the limiting portion 113 is a U-shaped slot, and the limiting matching portion 130 is a circular ring structure. When the clamping device 1 clamps the aluminum material in the electrolyte for anodizing treatment, when the electrolyte flows and pushes the aluminum material to move relative to the clamping device 1, the limiting matching portion 130 can move relative to the limiting portion 113 under the drive of the aluminum material to offset part of the driving force of the electrolyte on the aluminum material, and avoid deformation of the aluminum material under the driving force of the electrolyte, resulting in damage to the aluminum material.

[0090] In the above embodiments, the base 121 may be made of copper T1 alloy to improve the conductivity of the base 121, thereby improving the conductivity between the base 121 and the oxidized beam 11, and further improving the oxidation effect on the aluminum material.

[0091] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
