Abstract
Description
Technical Field
[0001] The embodiments of the utility model relate to a positioning device, and in particular to a positioning assembly and a positioning tool. Background Art
[0002] Chains, as a commonly used power transmission component or a conventional connecting component, have 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, it is necessary to electroplate the chain, such as chrome plating, nickel plating, copper plating, zinc plating, etc.
[0003] When electroplating a chain, the chain needs to be immersed in a plating tank containing a plating solution, and the portion of the chain to be plated is connected to the cathode, while the plating material acts as the anode. During the electroplating process, the metal ions of the plating material are reduced to metal atoms through electrode reactions under the action of an external electric field and transferred to the portion of the chain to be plated, thereby forming a metal deposition process on the portion of the chain to be plated. However, the inventors have discovered that since the chain is composed of multiple annular structures connected in sequence, it is inevitable that two adjacent annular structures will come into contact during the electroplating process, resulting in the contact portions of the inner side surfaces of the chain's annular structures being unable to be precipitated by the anode material, which can lead to uneven plating or plating failure on the inner side surfaces of the chain's annular structures. Utility Model Content
[0004] The purpose of the embodiment of the present utility model is to design a positioning component and a positioning tool so that when the chain is electroplated, the two adjacent annular structural parts of the chain can be completely separated to avoid direct contact, thereby ensuring the uniformity of the electroplating of the inner side surfaces of each annular structural part of the chain and improving the yield rate of the chain during electroplating.
[0005] In order to achieve the above-mentioned object, an embodiment of the present utility model provides a positioning assembly, which is used to position any annular structure of a chain, and the positioning assembly includes:
[0006] The first positioning assembly and the second positioning assembly are arranged opposite to each other along a preset straight line direction and are used to clamp and fix the annular structure of the chain;
[0007] The first positioning assembly is provided with a first slot on one side relative to the second positioning assembly, the first slot being used to engage the annular structure. The first positioning assembly is also movably connected to one of the support beams of the positioning fixture and is movable relative to the second positioning assembly.
[0008] The second positioning component is provided with a second slot on one side relative to the first positioning component, and the second slot is used to clamp the annular structure. The second positioning component is also movably connected to another support beam of the positioning tooling and is movable relative to the first positioning component.
[0009] In addition, an embodiment of the present utility model further provides a positioning tool, which is used to position the chain, and the positioning tool includes:
[0010] Four support beams, arranged in pairs in parallel and opposite to each other; the direction in which the two support beams in one group are opposite to each other is perpendicular to the direction in which the two support beams in another group are opposite to each other;
[0011] Several positioning components as described above are respectively arranged on four support beams; wherein, the number of the positioning components arranged on each of the support beams of any group is the same, and they are uniquely arranged, and any one of the positioning components is clamped with one of the annular structural parts of the positioning chain with another uniquely arranged positioning component.
[0012] Compared with the prior art, the embodiments of the present invention are as follows: since the positioning component includes: a first positioning component and a second positioning component, and the first positioning component and the second positioning component are arranged relative to each other along a preset straight line direction, at the same time, the first positioning component is provided with a first card slot on one side relative to the second positioning component, and similarly, the second positioning component is provided with a second card slot on one side relative to the first positioning component. In addition, the first positioning component and the second positioning component are movable relative to each other, so that the first positioning component and the second positioning component can respectively clamp any one of the annular structures of the chain through the first card slot and the second card slot, thereby ensuring that the annular structures of the chain are fixed during electroplating. Therefore, by clamping and fixing the annular structures, the annular structures of the chain can be separated from each other, avoiding direct contact between two adjacent annular structures, thereby ensuring the uniformity of electroplating on the inner side surfaces of the annular structures of the chain and improving the yield rate of the chain during electroplating.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clearly apparent, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will appreciate that many technical details are provided in the embodiments of the present invention to help readers better understand the present application. However, even without these technical details and the various variations and modifications based on the following embodiments, the technical solutions claimed in the present application can still be implemented.
[0020] Example 1
[0021] The first embodiment of the present invention relates to a positioning assembly, such as Figure 1 and Figure 2 As shown, the positioning assembly 1 is used to position any annular structure 101 of the chain 10, and, in combination with Figure 3 and Figure 4 As shown, the positioning assembly 1 includes a first positioning assembly 11 and a second positioning assembly 12. The first positioning assembly 11 and the second positioning assembly 12 are arranged opposite to each other along a preset straight line direction and are used to clamp and fix the annular structure 101 of the chain 10.
[0022] And, in some embodiments, as Figure 3 As shown, the first positioning component 11 is provided with a first slot 111 on one side of the second positioning component 12, which can be engaged with the annular structure 101. The first positioning component 11 is also movably connected to one of the support beams 2 of the positioning fixture, and the first positioning component 11 is also movable relative to the second positioning component 12. Figure 4 As shown, the second positioning component 12 is provided with a second slot 121 that can be clamped to the annular structure 101 on one side relative to the first positioning component 11, and the second positioning component 12 is also movably connected to another support beam 2 of the positioning tooling, and the second positioning component 12 is movable relative to the first positioning component 11.
[0023] It is not difficult to see from the above content that since the positioning component 1 includes: a first positioning component 11 and a second positioning component 12, and the first positioning component 11 and the second positioning component 12 are arranged relative to each other along a preset straight line direction, at the same time, the first positioning component 11 is provided with a first card slot 111 on one side relative to the second positioning component 12, and similarly, the second positioning component 12 is provided with a second card slot 121 on one side relative to the first positioning component 11, and in addition, the first positioning component 11 and the second positioning component 12 are movable relative to each other, so that the first positioning component 11 and the second positioning component 12 are movable relative to each other. The positioning component 12 can respectively clamp any annular structure 101 of the chain 10 through the first clamping groove 111 and the second clamping groove 121, thereby ensuring that the annular structures 101 of the chain 10 are fixed during electroplating. Therefore, by clamping and fixing the annular structures 101, the annular structures 101 of the chain 10 can be separated from each other, avoiding direct contact between two adjacent annular structures 101, thereby ensuring the uniformity of electroplating on the inner side surfaces of the annular structures 101 of the chain 10 and improving the yield rate of the chain 10 during electroplating.
[0024] Specifically, in some embodiments, Figure 3 As shown, the first positioning assembly 11 includes: a first movable rod 112, a first clamping member 113, a first head end locking member 114 and a first tail end locking member 115. The first movable rod 112 has a first head end 1121 and a first tail end 1122 away from the first head end 1121 along a preset straight line direction. Secondly, the first clamping member 113 is set at the first head end 1121 of the first movable rod 112. At the same time, as shown in FIG. Figure 3 and Figure 4 As shown, the first clamping member 113 is provided with a first clamping slot 111 on a side away from the first head end 1121. In addition, in some embodiments, as shown in FIG. Figure 3 and Figure 4 As shown, the first head end locking piece 114 and the first tail end locking piece 115 are arranged opposite to each other along the length direction of the first movable rod 112, and the first head end locking piece 114 and the first tail end locking piece 115 are both threadedly connected to the first movable rod 112, so that the first head end locking piece 114 and the first tail end locking piece 115 can be rotated around the axis direction of the first movable rod 112 respectively, and the first movable rod 112 can be rotated by the first head end locking piece 114 and the first tail end locking piece 115 respectively, so that the first movable rod 112 can move linearly along its length direction, and when the first movable rod 112 moves to the appropriate position, the first movable rod 112 can be locked on the support beam 2 by rotating the first head end locking piece 114 and the first tail end locking piece 115, so that the first clamping piece 113 can realize the clamping of the annular structure 101.
[0025] Similarly, corresponding to the structure of the first positioning component 11, the second positioning component 12 can adopt the same structure as the first positioning component 11, specifically, as follows Figure 3 and Figure 4 As shown, the second positioning assembly 12 includes: a second movable rod 122, a second clamping member 123, a second head end locking member 124 and a second tail end locking member 125. The second movable rod 122 has a second head end 1221 and a second tail end 1222 away from the second head end 1221 along a preset straight line direction. Secondly, the second clamping member 123 is provided at the second head end 1221 of the second movable rod 122. At the same time, a second clamping groove 121 is provided on the side of the second clamping member 123 away from the second head end 1221. In addition, in some embodiments, as Figure 1 As shown, the second head end locking piece 124 and the second tail end locking piece 125 are arranged opposite to each other along the length direction of the second movable rod 122, and the second head end locking piece 124 and the second tail end locking piece 125 are both threadedly connected to the second movable rod 122, so that the second head end locking piece 124 and the second tail end locking piece 125 can be rotated around the axis direction of the second movable rod 122 respectively, and the second movable rod 122 can be rotated by the second head end locking piece 124 and the second tail end locking piece 125 respectively, so that the second movable rod 122 can move linearly along its length direction, and when the second movable rod 122 moves to the appropriate position, the second movable rod 122 can be locked on the support beam 2 by rotating the second head end locking piece 124 and the second tail end locking piece 125, so that the second clamping piece 123 can realize the clamping of the annular structure 101.
[0026] It is not difficult to see from this that through the relative linear movement of the first movable rod 112 and the second movable rod 122, and when they move to the appropriate position, the first movable rod 112 and the second movable rod 122 can be locked, thereby ensuring the stability of the first clamping member 113 and the second clamping member 123 when clamping the annular structure 101.
[0027] In addition, in order to further improve the stability of the first clamping member 113 and the second clamping member 123 when clamping the annular structure 101 of the chain 10, in some embodiments, Figure 3 and Figure 5 As shown, the first clamping member 113 includes: a first support plate 1131 and a first claw 1132. The first support plate 1131 is connected to the first head end 1121 of the first movable rod 112, and the first claw 1132 is set on the side of the first support plate 1131 away from the first head end 1121. At the same time, the first claw 1132 is provided with at least one first slot 111. The second clamping member 123 can adopt the same structure as the first clamping member 113, specifically, combined with Figure 4 and Figure 6As shown, the second clamping member 123 includes: a second support plate 1231 and a second clamping claw 1232. The second support plate 1231 is connected to the second head end 1221 of the second movable rod 122, and the second clamping claw 1232 is arranged on the side of the second support plate 1231 away from the second head end 1221. At the same time, the second clamping claw 1232 is provided with at least one second clamping groove 121. It is not difficult to find from the above that since the first clamping claw 1132 is provided with at least one first clamping groove 111 and the second clamping claw 1232 is provided with at least one second clamping groove 121, any annular structure 101 of the chain 10 can be stably clamped by the clamping of the first clamping claw 1132 and the second clamping claw 1232.
[0028] Furthermore, as a preferred solution, in other embodiments, two first slots 111 are provided, and the two first slots 111 are perpendicular to each other and staggered. Similarly, two second slots 121 are provided, and the two second slots 121 are perpendicular to each other and staggered, so that the first clamping member 113 and the second clamping member 123 can respectively realize the clamping connection of the annular structure 101 in two directions, thereby further facilitating the clamping connection of the first clamping claw 1132 and the second clamping claw 1232 to the annular structure 101. Furthermore, it should be noted that, in other embodiments, the first slot 111 and the second slot 121 are both U-shaped slots or V-shaped slots. Therefore, when the annular structure 101 is inserted into the first slot 111 of the first claw 1132 and the second slot 121 of the second claw 1232, the positioning effect of the first slot 111 and the second slot 121 on the annular structure 101 can be improved, thereby ensuring the uniqueness of the position of the annular structure 101 after being inserted into the first slot 111 and the second slot 121.
[0029] Example 2
[0030] The second embodiment of the present invention relates to a positioning tool, such as Figure 1 and Figure 2 As shown, the positioning tool is used to position the chain 10, and the positioning tool includes: four support beams 2, and several positioning components 1 as described in Example 1.
[0031] And, as Figure 1 and Figure 2 As shown, among the four support beams 2, two are arranged in parallel and opposite to each other in a group, and the direction in which the two support beams 2 in one group are opposite to each other is perpendicular to the direction in which the two support beams 2 in another group are opposite to each other.
[0032] In addition, in other embodiments, Figure 1 and Figure 2As shown, each positioning component 1 is respectively arranged on four support beams 2, and the number of positioning components 1 arranged on each support beam 2 of any group is the same, and they are uniquely arranged, and any positioning component 1 is clamped with one of the annular structural parts 101 of the positioning chain 10 with another positioning component 1 that is uniquely arranged.
[0033] It is not difficult to see from the above content that since each positioning component 1 is respectively arranged on each support beam 2, and the number of positioning components 1 arranged on each support beam 2 of any group is the same, and they are uniquely arranged, at the same time, any positioning component 1 is clamped with another positioning component 1 that is uniquely arranged to position one of the annular structures 101 of the positioning chain 10. By clamping and positioning the annular structures 101 of the chain 10, the annular structures of the chain can be separated from each other, thereby ensuring that the annular structures 101 of the chain 10 are fixed during electroplating. Therefore, by clamping and fixing the annular structures 101, direct contact between two adjacent annular structures 101 is avoided, thereby ensuring the uniformity of the electroplating of the inner side surfaces of the annular structures 101 of the chain 10, and improving the yield rate of the chain 10 during electroplating.
[0034] Specifically, combined Figure 3 and Figure 4 As shown, each support beam 2 is provided with a plurality of connection holes (not shown) through which the first positioning assembly 11 and the second positioning assembly 12 can pass. This allows the first movable rod 112 of the first positioning assembly 11 to move linearly along its length under the rotation of the first head-end locking member 114 and the first tail-end locking member 115. Simultaneously, the second movable rod 122 of the second positioning assembly 12 can also move linearly along its length under the rotation of the second head-end locking member 124 and the second tail-end locking member 125, thereby achieving the clamping and fixing of each ring-shaped structural member 101 of the chain 10.
[0035] In addition, in order to support and fix each support beam 2, in other embodiments, such as Figure 1 and Figure 2 As shown, the positioning fixture also includes: a first side plate 3 and a second side plate 4. The first side plate 3 is connected to one end of each support beam 2 along the length of each support beam 2. Simultaneously, the second side plate 4 is connected to the other end of each support beam 2 along the length of each support beam 2. By connecting the first side plate 3 and the second side plate 4 to both ends of each support beam 2, each support beam 2 can be supported and fixed, thereby ensuring uniform electroplating of the inner side surfaces of each annular structural member 101 of the chain 10 and further improving the yield rate of the chain 10 during electroplating.
[0036] Furthermore, it should be noted that, in some embodiments, each support beam 2 may be an insulating component, such as a plastic component, so that each support beam 2 can conveniently guide the cathode so that the cathode can abut against each annular structural component 101 of each chain 10.
[0037] Those skilled in the art will appreciate that the above embodiments are specific implementations of the present invention, and that in actual applications, various changes may be made in form and detail without departing from the spirit and scope of the present invention.
