Description

Technical Field

[0001] The embodiments of the present invention belong to the field of chain electroplating, and in particular relate to a positioning component, a positioning tool, a chain electroplating device and a chain positioning method. Background Art

[0002] Chain, as a commonly used power transmission part or as a conventional connecting part, has been widely used in various fields. In some fields, in order to enhance the mechanical properties, wear resistance and / or rust resistance of the chain, the chain needs to be electroplated, such as chrome plating, nickel plating, copper plating, zinc plating, etc.

[0003] When electroplating a chain, the chain needs to be immersed in an electroplating tank containing an electroplating solution, and the part of the chain to be electroplated is connected to the cathode, and the electroplating material is used as the anode. During the electroplating process, the metal ions of the electroplating material are reduced to metal materials through electrode reactions under the action of an external electric field, and transferred to the part of the chain to be electroplated, so that a metal deposition process is formed at the part of the chain to be electroplated. However, the inventors have found that since the chain is composed of a plurality of annular structural parts connected in sequence, it is inevitable that two adjacent annular structural parts will come into contact during the electroplating process, resulting in the contact parts of the inner side surfaces of the annular structural parts of the chain being unable to be precipitated by the anode, which will cause uneven electroplating or electroplating failure on the inner side surfaces of the annular structural parts of the chain. Summary of the invention

[0004] The purpose of the embodiments of the present invention is to design a positioning assembly, a positioning tool, a chain electroplating device and a chain positioning method, so that when the chain is electroplated, two adjacent annular structures of the chain can be completely separated to avoid direct contact, thereby ensuring the uniformity of the electroplating on the inner side surfaces of each annular structure of the chain, thereby improving the yield rate of the chain during electroplating.

[0005] In order to achieve the above object, an embodiment of the present invention provides a positioning assembly, which is used to clamp any annular structure of a positioning chain, and the positioning assembly includes:

[0006] The first clamping member and the second clamping member are arranged opposite to each other, so that the annular structure is clamped between the first clamping member and the second clamping member, and at least the inner side of the annular structure is exposed outside the first clamping member and the second clamping member, and is used to receive the metal material formed by electrode reaction reduction from the anode;

[0007] Wherein, the first clamping member and the second clamping member are both insulating components, and the first clamping member and / or the second clamping member are also used to be penetrated by the cathode so that the cathode abuts against the annular structure.

[0008] In addition, an embodiment of the present invention further provides a positioning tool, comprising:

[0009] Several positioning assemblies as described above; each of the positioning assemblies is sequentially connected along the length direction of the chain, and the number of the positioning assemblies is the same as the number of the annular structural members of the chain, and they are uniquely arranged, and each of the positioning assemblies is also respectively engaged with the uniquely arranged annular structural member;

[0010] Wherein, each two adjacent positioning components are arranged crosswise and perpendicularly to each other, and each two adjacent annular structures are clamped and fixed in directions perpendicular to each other, so that each two adjacent annular structures are separated from each other.

[0011] In addition, an embodiment of the present invention further provides a chain electroplating device, wherein the chain positioning device comprises:

[0012] The positioning tool as described above; wherein each of the positioning components of the positioning tool is respectively clamped with the only corresponding annular structural members along the length direction of the chain;

[0013] Cathode assembly; the cathode assembly comprises: a plurality of cathode parts, the number of the cathode parts is the same as the number of the positioning components, and they are uniquely corresponding; each of the cathode parts is partially inserted into the uniquely corresponding positioning component and abuts against the uniquely corresponding annular structure; each of the cathode parts is also partially exposed outside the uniquely corresponding positioning component and is externally connected to a power source;

[0014] The anode assembly is arranged on the positioning fixture so that the metal material formed after reduction by electrode reaction is transferred to the inner side surface of each of the annular structural members.

[0015] In addition, an embodiment of the present invention further provides a chain positioning method, comprising the following steps:

[0016] Provide positioning tooling;

[0017] The positioning components of the positioning tool are sequentially clamped to the annular structures of the chain along the length direction of the chain, so that the inner side surface of each annular structure is at least exposed outside the positioning components;

[0018] Among them, the number of the positioning components is the same as the number of the annular structures, and they are uniquely arranged. Every two adjacent positioning components are arranged crosswise and perpendicularly to each other, and every two adjacent annular structures are clamped and fixed in directions perpendicular to each other, so that every two adjacent annular structures are separated from each other.

[0019] Compared with the prior art, the embodiments of the present invention have a positioning component that includes a first clamping member and a second clamping member, and the first clamping member and the second clamping member are arranged opposite to each other, so that the annular structure can be clamped between the first clamping member and the second clamping member. Therefore, when any annular structure of the chain is clamped and fixed by the first clamping member and the second clamping member, the inner side surface of the annular structure can be exposed outside the first clamping member and the second clamping member. In addition, since the first clamping member and the second clamping member are both insulating components, the metal material formed by the anode member after reduction by the electrode reaction can be isolated by the first clamping member and the second clamping member, so that the metal material cannot be transferred to the part covered by the first clamping member and the second clamping member, but can only be transferred to the inner side surface of the annular structure, thereby completing the electroplating of the inner side surface of the annular structure and ensuring the uniformity of the electroplating of the inner side surfaces of each annular structure of the chain.

[0020] In addition, since the positioning tooling includes a plurality of positioning components, and each positioning component is connected in sequence along the length direction of the chain, and the number of positioning components is the same as the number of annular structures of the chain, and they are uniquely arranged, and at the same time, each two adjacent positioning components are arranged crosswise and perpendicularly to each other, before electroplating the chain, each positioning component can be respectively clamped with the uniquely corresponding annular structure, so that each two adjacent annular structures can be clamped and fixed in a direction perpendicular to each other, so that each two adjacent annular structures of the chain can be separated from each other, thereby ensuring the uniformity of the electroplating on the inner side of each annular structure, thereby improving the yield rate of the chain during electroplating.

[0034] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present invention, many technical details are provided to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can be implemented.

[0035] Embodiment 1

[0036] A first embodiment of the present invention relates to a positioning assembly, such as Figure 1 , Figure 2 and Figure 3 As shown, the positioning assembly 1 is used to clamp any annular structure 101 of the positioning chain 10 , and the positioning assembly 1 includes: a first clamping member 11 and a second clamping member 12 .

[0037] In some embodiments, in combination Figure 1 , Figure 2 and Figure 3As shown, the first clamping member 11 and the second clamping member 12 are arranged opposite to each other, so that the annular structure 101 is clamped between the first clamping member 11 and the second clamping member 12, and at least the inner side surface 1011 of the annular structure 101 is exposed outside the first clamping member 11 and the second clamping member 12, for receiving the metal material formed by electrode reaction reduction from the anode member 21.

[0038] In addition, in some embodiments, the first clamping member 11 and the second clamping member 12 are both insulating components, and are combined with Figure 3 and Figure 6 As shown, the first clamping member 11 and / or the second clamping member 12 is also used to be penetrated by the cathode member 31 so that the cathode member 31 abuts against the annular structure member 101 .

[0039] It is not difficult to see from the above content that since the positioning assembly 1 includes the first clamping member 11 and the second clamping member 12, and the first clamping member 11 and the second clamping member 12 are arranged opposite to each other, the annular structure 101 can be clamped between the first clamping member 11 and the second clamping member 12, so that when any annular structure 101 of the chain 10 is clamped and fixed by the first clamping member 11 and the second clamping member 12, the inner side 1011 of the annular structure 101 can be exposed outside the first clamping member 11 and the second clamping member 12, and since the first The clamping member 11 and the second clamping member 12 are both insulating components, so that the metal material formed by the reduction of the anode member 21 through the electrode reaction can be isolated by the first clamping member 11 and the second clamping member 12, so that the metal material cannot be transferred to the part covered by the first clamping member 11 and the second clamping member 12, but can only be transferred to the inner side surface 1011 of the annular structure 101, thereby completing the electroplating of the inner side surface 1011 of the annular structure 101, and ensuring the uniformity of the electroplating of the inner side surface 1011 of each annular structure 101 of the chain 10.

[0040] Specifically, in some embodiments, Figure 1 As shown, a first clamping groove 111 is provided on one side of the first clamping member 11 relative to the second clamping member 12, and a second clamping groove 121 is provided on one side of the second clamping member 12 relative to the first clamping member 11. Moreover, the groove wall of the first clamping groove 111 of the first clamping member 11 at least fits with the outer side of the annular structure 101, and the groove wall of the second clamping groove 121 of the second clamping member 12 at least fits with the outer side of the annular structure 101, so that an annular area 13 is formed between the first clamping member 11 and the second clamping member 12, which can be used for the metal material formed by the anode reduction through the electrode reaction and transferred to the inner side surface 1011 of the annular structure 101.

[0041] In addition, it is worth mentioning that in some embodiments, Figure 1 and Figure 4As shown, the first clamping member 11 and the second clamping member 12 clamp and position the annular structure 101 along the width direction of the annular structure 101. Fig.11 As shown, the first clamping member 11 and the second clamping member 12 can also clamp and position the annular structure 101 along the length direction of the annular structure 101. Figure 1 and Figure 4 As shown, the first clamping member 11 and the second clamping member 12 are also provided with a channel 14 connected to the annular area 13, through which the electrolyte solution in the liquid tank can enter the annular area 13, so that the metal material formed by each anode member 21 after reduction by the electrode reaction can enter the annular area 13 through the electrolyte solution and the channel 14 of each first clamping member 11 and the second clamping member, and be transferred to the inner side surface 1011 of the annular structure 101, thereby realizing the electroplating of the inner side surface 1011 of the annular structure 101.

[0042] Furthermore, it should be noted that, in some embodiments, the channel 14 may be provided on the first clamping member 11 and the second clamping member 12, respectively, or in other embodiments, such as Figure 1 and Figure 4 As shown, the channel 14 may also include: a first liquid tank 141 disposed on the first clamping member 11, and a second liquid tank 142 disposed on the second clamping member 12. Specifically, the first liquid tank 141 may be disposed on a side of the first clamping member 11 relative to the second clamping member 12, and the second liquid tank 142 may be disposed on a side of the second clamping member 12 relative to the first clamping member 11, so that when the first clamping member 11 and the second clamping member 12 complete the clamping of the annular structure 101, the first liquid tank 141 and the second liquid tank 142 may be opposite to each other and jointly enclose the channel 14, and the channel 14 may extend along the length direction of the chain 10, and the channel 14 may be used to allow the electrolyte solution to enter the annular region 13. Therefore, after the first clamping member 11 and the second clamping member 12 complete the clamping and fixing of the annular structure 101, the first liquid tank 141 and the second liquid tank 142 can jointly form a channel 14, so that the metal material formed by each anode member 21 after electrode reaction reduction can enter the annular area 13 through the electrolyte solution through the channel 14.

[0043] In addition, it is worth mentioning that in some other embodiments, such as Figure 4 , Figure 5 and Figure 6As shown, the first clamping member 11 and / or the second clamping member 12 are detachably provided with a locking member 15, and the locking member 15 is used to fix the anode member 21, so that a portion of the anode member 21 enters the annular area 13 surrounded by the first clamping member 11 and the second clamping member 12. For example, the locking member 15 can be a bolt, and the bolt is threadedly connected to the first clamping member 11 and / or the second clamping member 12, so that the locking member 15 can realize the locking and fixing of the anode member 21 on the first clamping member 11 and / or the second clamping member 12.

[0044] Furthermore, it should be noted that when the first clamping member 11 and the second clamping member 12 are clamped and positioned along the width direction of the annular structure 101, in order to enable the first clamping member 11 to clamp and fix the annular structure 101 through the first clamping groove 111, in some embodiments, such as Figure 6 As shown, the first clamping member 11 includes: a first upper shielding cover 112 and a first lower shielding cover 113, and the first upper shielding cover 112 and the first lower shielding cover 113 can be arranged relative to each other along the thickness direction of the annular structure 101, so that a first clamping groove 111 can be formed between the first upper shielding cover 112 and the first lower shielding cover 113. Therefore, when the annular structure 101 is clamped and fixed, the annular structure 101 can be embedded in the first upper shielding cover 112 and the first lower shielding cover 113 respectively, so that the first clamping member 11 can realize the clamping of the annular structure 101 through the first clamping groove 111.

[0045] Similarly, in order to enable the second clamping member 12 to clamp and fix the annular structure 101, in other embodiments, such as Figure 6 As shown, the second clamping member 12 includes: a second upper shielding cover 122 and a second lower shielding cover 123, and the second upper shielding cover 122 and the second lower shielding cover 123 can be arranged relative to each other along the thickness direction of the annular structure 101, so that a second clamping groove 121 can be formed between the second upper shielding cover 122 and the second lower shielding cover 123. Therefore, when the annular structure 101 is clamped and fixed, the annular structure 101 can be embedded in the second upper shielding cover 122 and the second lower shielding cover 123 respectively, so that the second clamping member 12 can realize the clamping of the annular structure 101 through the second clamping groove 121.

[0046] Embodiment 2

[0047] Embodiment 2 of the present invention relates to a positioning tool, such as Fig. 9 As shown, the positioning tooling includes: a plurality of positioning components 1 as described in the first embodiment. Among them, each positioning component 1 is sequentially connected along the length direction of the chain 10, and the number of the positioning components 1 is the same as the number of the annular structural members 101 of the chain 10, and they are uniquely arranged, and each positioning component 1 is also respectively clamped with the uniquely corresponding annular structural member 101.

[0048] Among them, Fig.10 As shown, every two adjacent positioning components 1 are arranged crosswise and perpendicularly to each other, and every two adjacent annular structures 101 are clamped and fixed in directions perpendicular to each other, so that every two adjacent annular structures 101 are separated from each other.

[0049] It is not difficult to see from the above content that since the positioning tooling includes a plurality of positioning components 1, and each positioning component 1 is connected in sequence along the length direction of the chain 10, and the number of positioning components 1 is the same as the number of annular structures 101 of the chain 10, and they are uniquely arranged, and at the same time, each two adjacent positioning components 1 are cross-arranged vertically with each other, before electroplating the chain 10, each positioning component 1 can be respectively clamped with the uniquely corresponding annular structure 101, so that each two adjacent annular structures 101 can be clamped and fixed in a direction perpendicular to each other, so that each two adjacent annular structures 101 of the chain can be separated from each other, thereby ensuring the uniformity of the electroplating of the inner side surface 1011 of each annular structure 101, thereby improving the yield rate of the chain 10 during electroplating.

[0050] Specifically, in some embodiments, along the length direction of the chain 10, the first clamping member 11 and the second clamping member 12 of each positioning component 1 are integrally formed along the length direction of the chain 10, so that each positioning component 1 can be fixed relative to each other along the length direction of the chain 10, so that after each positioning component 1 of the positioning tooling is clamped and fixed to each annular structure 101 of the chain 10, the position of each annular structure 101 is unique, so that every two adjacent annular structures 101 can be separated from each other, thereby ensuring the uniformity of the electroplating of the inner side surface 1011 of each annular structure 101, and improving the yield rate of the chain 10 during electroplating.

[0051] Of course, as an alternative, in other embodiments, such as Fig. 9 and Fig.10 As shown, along the length direction of the chain 10, the first clamping member 11 and the second clamping member 12 of each positioning component 1 are detachably connected along the length direction of the chain 10. For example, the positioning components 1 can be connected by clamping or by locking members. Therefore, after the positioning components 1 of the positioning tooling are clamped and fixed to the annular structures 101 of the chain 10, each two adjacent annular structures 101 can also be separated from each other, thereby ensuring the uniformity of the electroplating of the inner side surface 1011 of each annular structure 101 and improving the yield rate of the chain 10 during electroplating.

[0052] Furthermore, in order to ensure the stability of each positioning assembly 1 when it is clamped and positioned with the only corresponding annular structure 101, Figure 7 and Figure 8As shown, the positioning fixture further includes: a base 200, and the base 200 has a first mounting side 2001 and a second mounting side 2002, and the first mounting side 2001 and the second mounting side 2002 are perpendicular to each other. The first mounting side 2001 and the second mounting side 2002 can be used to respectively realize the installation and fixation of each positioning component 1, so that each two adjacent positioning components 1 can be arranged perpendicularly and staggered to each other, thereby improving the stability of each positioning component 1 when it is clamped and positioned to the unique corresponding annular structure 101, and ensuring the uniformity of electroplating of the inner side surface 1011 of each annular structure 101.

[0053] Embodiment 3

[0054] Embodiment 3 of the present invention relates to a chain electroplating device, such as Fig. 9 As shown, the chain positioning device includes: the positioning tool as described in the second embodiment, the cathode assembly 3 and the anode assembly 2.

[0055] Among them, Fig. 9 and Fig.10 As shown, each positioning assembly 1 of the positioning tool is respectively clamped with each corresponding annular structure 101 along the length direction of the chain 10, and the number of cathode components 31 is the same as the number of positioning assemblies 1, and they are uniquely corresponding. Each cathode component 31 is partially inserted into the uniquely corresponding positioning assembly 1 and abuts against the uniquely corresponding annular structure 101. At the same time, each cathode component 31 is also partially exposed outside the uniquely corresponding positioning assembly 1 and is externally connected to a power source.

[0056] In addition, in some other embodiments, Figure 1 As shown, the anode assembly 2 is disposed on a positioning fixture so that the metal material formed by the anode assembly 2 after electrode reaction reduction is transferred to the inner side surface 1011 of each annular structure 101 .

[0057] It is not difficult to see from the above content that since the positioning tooling includes a plurality of positioning components 1, and each positioning component 1 is connected in sequence along the length direction of the chain 10, and the number of positioning components 1 is the same as the number of annular structures 101 of the chain 10, and they are uniquely arranged, and at the same time, each two adjacent positioning components 1 are cross-arranged vertically with each other, before electroplating the chain 10, each positioning component 1 can be respectively clamped with the uniquely corresponding annular structure 101, so that each two adjacent annular structures 101 can be clamped and fixed in a direction perpendicular to each other, so that each two adjacent annular structures 101 of the chain can be separated from each other, thereby ensuring the uniformity of the electroplating of the inner side surface 1011 of each annular structure 101, thereby improving the yield rate of the chain 10 during electroplating.

[0058] Specifically, in some embodiments, Figure 8 and Fig. 9As shown, the anode assembly 2 includes: a plurality of anode pieces 21, and each anode piece 21 extends along the length direction of the chain 10, and is combined with Fig.11 As shown, at least one anode member 21 passes through the intersection area of ​​each two adjacent positioning components 1 .

[0059] Furthermore, in order to realize the positioning of each anode member 21 on the positioning tool, in other embodiments, such as Fig.11 As shown, the chain electroplating device further includes: a hanging assembly 4, and the hanging assembly 4 includes: a hanging member 41 and at least one positioning member 42. Among them, the hanging member 41 is hung on the positioning tooling, and, as shown in FIG. Fig.12 As shown, the hanging member 41 has a head end 411 and a tail end 412 away from the head end 411. Fig.11 As shown, the hanging member 41 has at least one bent portion 413 from the head end 411 to the tail end 412 , so that the head end 411 and the tail end 412 are opposite to each other.

[0060] In addition, in some other embodiments, Fig.11 and Fig.12 As shown, each positioning member 42 is arranged on the hanging member 41. Moreover, when there are multiple positioning members 42, each positioning member 42 is sequentially arranged from the head end 411 to the tail end 412, and each positioning member 42 is used to fix the anode member 21, so that the fixed anode member 21 is positioned in the intersection area of ​​each adjacent two positioning components 1 of the positioning tool.

[0061] Furthermore, it should be noted that in other embodiments, such as Fig.11 As shown, the bending portion 413 has several, for example, Fig.12 As shown, the bending portion 413 at least includes: a first side bending portion 413A, a second side bending portion 413B and a top bending portion 413C. Figure 1 and Figure 2 As shown, the first side bending portion 413A includes: a plurality of first bending segments 413A1 formed by bending several times from the head end 411 toward the top direction of the positioning tooling. Secondly, the second side bending portion 413B includes: a plurality of second bending segments 413B1 formed by bending several times from the tail end 412 toward the top direction of the positioning tooling. Finally, the top bending portion 413C is respectively connected to an end of the first side bending portion 413A away from the head end 411 and an end of the second side bending portion 413B away from the tail end 412. Through the multiple first bending segments 413A1 of the first side bending portion 413A and the multiple second bending segments 413B1 of the second side bending portion 413B, the head end 411 and the tail end 412 of the hanger 41 can be opposite to each other, and, in combination with Figure 1 and Figure 2 As shown, in other embodiments, combined with Fig.12As shown, the first side bending portion 413A, the second side bending portion 413B and the top bending portion 413C are also respectively provided with at least one positioning member 42, so that the hanging assembly 4 can respectively realize the positioning of multiple anode components 21 around the circumference of the positioning tooling, thereby further ensuring the uniformity of the electroplating of the inner side surface 1011 of each annular structural component 101 of the chain 10.

[0062] Of course, as an alternative, in other embodiments, such as Figure 7 As shown, each anode member 21 of the anode assembly 2 is partially guided into the gap formed between any two adjacent annular structures 101, so that the metal material formed by the electrode reaction of each anode member 21 is transferred to the joint of the inner side surfaces 1011 of the two adjacent annular structures 101.

[0063] Embodiment 4

[0064] Embodiment 4 of the present invention relates to a chain positioning method, such as Fig.13 As shown, the chain positioning method includes the following steps:

[0066] Step 1320 , clamp each positioning component 1 of the positioning tool to each annular structure 101 of the chain 10 in sequence along the length direction of the chain 10 , so that the inner side surface 1011 of each annular structure 101 is at least exposed outside each positioning component 1 .

[0067] Among them, the number of positioning components 1 is the same as the number of annular structures 101, and they are uniquely arranged. Every two adjacent positioning components 1 are arranged crosswise and perpendicularly to each other, and every two adjacent annular structures 101 are clamped and fixed in directions perpendicular to each other, so that every two adjacent annular structures 101 are separated from each other.

[0068] It is not difficult to see from the above content that since the positioning tooling includes a plurality of positioning components 1, and each positioning component 1 is connected in sequence along the length direction of the chain 10, and the number of positioning components 1 is the same as the number of annular structures 101 of the chain 10, and they are uniquely arranged, and at the same time, each two adjacent positioning components 1 are cross-arranged vertically with each other, before electroplating the chain 10, each positioning component 1 can be respectively clamped with the uniquely corresponding annular structure 101, so that each two adjacent annular structures 101 can be clamped and fixed in a direction perpendicular to each other, so that each two adjacent annular structures 101 of the chain can be separated from each other, thereby ensuring the uniformity of the electroplating of the inner side surface 1011 of each annular structure 101, thereby improving the yield rate of the chain 10 during electroplating.

[0069] Furthermore, it should be noted that this embodiment is an embodiment of the chain positioning method corresponding to the second embodiment, and this embodiment can be implemented in conjunction with the second embodiment. In addition, the relevant technical details mentioned in the second embodiment are still valid in this embodiment, and in order to reduce repetition, they are not repeated here. Accordingly, the relevant technical details mentioned in this embodiment can also be applied in the second embodiment.
