Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, and in particular to a steel collar electroplating fixture. Background Technology

[0002] Before use, steel rings are usually electroplated to improve their hardness, wear resistance, and corrosion resistance, thereby extending their service life.

[0003] When electroplating steel rings, a mounting bracket is typically used to fix the steel ring to the bracket, then immerse it in the electroplating solution. Electroplating is then performed by applying electricity. Currently used mounting brackets include an electroplating device with patent number CN202221610814.3 that can homogenize the plating thickness of the inner ring of a steel ring track. This device includes a steel ring cathode holder, a base anode, an auxiliary anode, an anode support, and an auxiliary anode column. The cathode holder supports the steel ring base, the auxiliary anode is located in the inner ring of the steel ring track, and is fixed to the auxiliary anode column. The cathode holder is electrically connected to the negative terminals of both the base DC power supply and the auxiliary DC power supply, while the base anode is electrically connected to the positive terminal of the base DC power supply. The voltage difference between the inner ring of the track and the auxiliary anode is greater than the voltage difference between the steel ring and the base anode. Thus, after electroplating, the metal plating thickness on the inner ring surface of the track is greater than the plating thickness on the outer surface of the track. If the outer ring shape of the auxiliary anode is designed to correspond to the shape of the inner ring of the steel ring, and an equal pressure gap is maintained between them, the uniformity of the plating thickness of the inner ring can be improved, ensuring the final roundness and surface quality of the inner ring. Using steel ring cathode holders to fix the steel ring results in uneven electroplating on the surface, leading to low product quality. Furthermore, installation requires clamping the steel ring between multiple cathode holders, making the installation process slow.

[0004] To address the aforementioned problems, this utility model document proposes a steel collar electroplating fixture. Utility Model Content

[0005] This utility model provides a steel collar electroplating fixture, which improves the uniformity of the electroplating layer on the surface of the steel collar, ensures product quality, and at the same time increases the clamping speed of the steel collar, thereby improving work efficiency.

[0006] This utility model provides the following technical solution:

[0007] A steel collar electroplating fixture includes a main rod with a conductive hook at the top. Multiple positioning plates are evenly arranged along the height of the main rod, and the middle of each positioning plate is fixed to the main rod. The positioning plate near the top of the main rod has upper clamping members symmetrically arranged at both ends to press the steel collar, while the positioning plate near the bottom of the main rod has lower support members symmetrically arranged at both ends to support the steel collar. The positioning plate between these two positioning plates has lower support members and upper clamping members symmetrically arranged at both ends.

[0008] Furthermore, the lower support includes a first mounting plate with a first mounting hole, and symmetrical support plates on opposite sides of the first mounting plate. One side of the support plate is connected to the first mounting plate, and the other symmetrical side has a first positioning groove. The angle between the support plate and the first mounting plate is 60° to 120°.

[0009] Furthermore, the upper clamping member includes a "U"-shaped elastic connecting plate. One end of the elastic connecting plate is provided with a second mounting plate, and the other end is provided with an adjusting plate. The second mounting plate has a second mounting hole, and the adjusting plate has a positioning hole. A third mounting plate is inserted into the positioning hole, and the third mounting plate is located on the downward adjusting side. One side of the third mounting plate is provided with a locking block that matches the positioning hole, and the opposite side is provided with a pressure plate. One side of the pressure plate is connected to the third mounting plate, and the opposite side has a second positioning groove. The position of the pressure plate corresponds to the middle of the lower support member.

[0010] Furthermore, the positioning plate is a strip-shaped structure with a third mounting hole in the middle and a fourth mounting hole symmetrically opened near both ends. The two ends of the positioning plate rotate relative to the central axis of the positioning plate, with an angle of 60°~90° with the middle, and the two ends are symmetrically arranged relative to the middle.

[0011] Furthermore, a connecting hook is provided at the bottom end of the main rod.

[0012] Furthermore, the main rod is provided with a plurality of fifth mounting holes evenly distributed along the height direction.

[0013] In this invention, the steel ring is placed on the lower support and then pressed onto the lower support by the upper clamping member to complete the clamping and fixing of the steel ring. This greatly improves the clamping speed of the steel ring and increases the work efficiency of the workers. In addition, it reduces the coverage area of ​​the steel ring surface when fixing the steel ring, which is more conducive to the uniform electroplating layer on the surface of the steel ring during electroplating and improves product quality.

[0029] Example:

[0030] Reference Figure 1 and Figure 2As shown, a steel collar electroplating fixture includes a main rod 1. The top of the main rod 1 is provided with a conductive hook 5. Multiple positioning plates 2 are evenly arranged along the height direction of the main rod 1. The middle part of the positioning plate 2 is fixed on the main rod 1. The two ends of the positioning plate 2 near the top of the main rod 1 are symmetrically provided with upper clamping members 4 to press the steel collar. The two ends of the positioning plate 2 near the bottom of the main rod 1 are symmetrically provided with lower support members 3 to support the steel collar. The two ends of the positioning plate 2 located between the two positioning plates 2 are symmetrically provided with lower support members 3 and upper clamping members 4.

[0031] The conductive hook 5 is used to connect to an external flybar and can be powered on. The steel ring is supported by the lower support member 3, and then the steel ring is pressed onto the lower support member 3 by the upper clamping member 4, thus completing the clamping of the steel ring. During the clamping process, the worker only needs to lift the upper clamping member 4, place the steel ring on the lower support member 3, and then release the upper clamping member 4, which greatly improves the clamping speed of the steel ring and improves the work efficiency.

[0032] Reference Figure 3 As shown, the lower support member 3 includes a first mounting plate 301, on which a first mounting hole 303 is opened. Support plates 302 are symmetrically arranged on opposite sides of the first mounting plate 301. One side of the support plate 302 is connected to the first mounting plate 301, and the other side is provided with a first positioning corner groove 304. The included angle between the support plate 302 and the first mounting plate 301 is 60°~120°.

[0033] The first mounting plate 301 is fixed to the positioning plate 2 by bolts and nuts through the first mounting hole 303. The two support plates 302 support the steel ring, improve the stability of the steel ring, and greatly reduce the occlusion area on the surface of the steel ring, which is beneficial to the uniformity of electroplating. The first positioning corner groove 304 on the support plate 302 is used to hold the steel ring, ensuring that the edge of the steel ring will not slip when placed in the first positioning corner groove 304.

[0034] The included angle between the support plate 302 and the first mounting plate 301 is used to adjust the angle of the first positioning angle groove 304, further improving the stability of the steel ring after it is placed in the first positioning angle groove 304, and ensuring that the steel ring will not move in the first positioning angle groove 304 under the action of the upper clamping member 4.

[0035] Reference Figure 4 , Figure 5 and Figure 6As shown, the upper clamping member 4 includes a "U"-shaped elastic connecting plate 401. One end of the elastic connecting plate 401 is provided with a second mounting plate 402, and the other end is provided with an adjusting plate 404. The second mounting plate 402 has a second mounting hole 403, and the adjusting plate 404 has a positioning hole 405. A third mounting plate 406 is inserted into the positioning hole 405, and the third mounting plate 406 is located on the downward adjusting side. One side of the third mounting plate 406 is provided with a locking block 407 that matches the positioning hole 405, and the opposite side is provided with a pressure plate 408. One side of the pressure plate 408 is connected to the third mounting plate 406, and the opposite side has a second positioning corner groove 409. The position of the pressure plate 408 corresponds to the middle of the lower support member 3.

[0036] The second mounting plate 402 is fixed to the positioning plate 2 through the second mounting hole 403 with bolts and nuts, thereby fixing the position of the elastic connecting plate 401. The third mounting plate 406 is fixed to the adjusting plate 404 at the upper end of the elastic connecting plate 401 through the cooperation of the locking block 407 and the positioning locking hole 405. The edge of the steel ring is locked in the second positioning corner groove 409 on the pressure plate 408 to prevent the steel ring from being unstable due to the elastic force of the elastic connecting plate 401.

[0037] The position of the pressure plate 408 corresponds to the middle of the lower support 3, ensuring that the force received by the steel ring is balanced, thereby ensuring the stability of the steel ring position and improving the stability of the steel ring clamping.

[0038] The adjusting plate 404 can adjust the angle of the pressing plate 408, thereby adjusting the clamping angle between the second positioning groove 409 and the steel ring, as well as the fitting angle between the upper clamping member 4 and the lower support member 3.

[0039] Reference Figure 7 As shown, the positioning plate 2 is a strip-shaped structure with a third mounting hole 201 in the middle and a fourth mounting hole 202 symmetrically opened near both ends. The two ends of the positioning plate 2 rotate relative to the central axis of the positioning plate 2, with an angle of 60°~90° with the middle, and the two ends are symmetrically arranged relative to the middle.

[0040] The positioning plate 2 is fixed to the main rod 1 by bolts and nuts through the third mounting hole 201. The fourth mounting hole 202 is used to install the upper clamping member 4 and the lower support member 3. The fourth mounting holes 202 are symmetrically arranged so that the upper clamping member 4 and the lower support member 3 installed on the positioning plate 2 are also symmetrically distributed, ensuring the balance of force on the main rod 1 and preventing the main rod 1 from tilting, which would affect the uniformity of electroplating.

[0041] The two ends of the positioning plate 2 are twisted by 60°~90°. On the one hand, this ensures that the lower support 3 can cooperate with the upper clamping part 4. On the other hand, it adjusts the clamping angle of the steel ring so that the weight of the steel ring acts on the lower support 3, preventing the steel ring from falling off the lower support 3 under the action of gravity.

[0042] The bottom of the main rod is equipped with a connecting hook 6.

[0043] The connecting hook 6 facilitates connecting multiple main rods 1 into a whole, meeting the needs of large-scale production in enterprises, preventing interference or even collisions between adjacent main rods 1, which would affect the normal electroplating process.

[0044] Reference Figure 8 As shown, the main rod 1 has multiple fifth mounting holes 101 evenly distributed along its height. The fifth mounting holes 101 facilitate the installation of the positioning plate 2.

[0045] In use, the first mounting plate 301 and the second mounting plate 402 are bolted through the first mounting hole 303, the second mounting hole 403 and the fourth mounting hole 202 and locked with nuts to the positioning plate 2. The positioning plate 2 is bolted through the third mounting hole 201 and the fifth mounting hole 101 and locked with nuts to fix the positioning plate 2 to the main rod 1. The steel ring is placed in the first positioning groove 304 of the support plate 302. The steel ring is supported by the two support plates 302. At the same time, the steel ring will compress the elastic connecting plate 401 upward. Then, the second positioning groove 409 on the pressure plate 408 is locked into the top edge of the steel ring. The steel ring can be pressed and fixed by the elastic force of the elastic connecting plate 401. Then, it is suspended on the external flybar through the conductive hook 5 into the main cylinder for electroplating operation.

[0046] In practical use, an insulating layer is provided on the surfaces of the main rod 1, positioning plate 2, first mounting plate 301, support plate 302, second mounting plate 402, elastic connecting plate 401, adjusting plate 404, and the bolts and nuts used for connection, so as to avoid the formation of an electroplating layer on the surface of the above components during electroplating, thus avoiding waste of resources.

[0047] A reinforcing rod is installed along the height of the main rod 1. Since the main rod 1 is made of copper busbar, it will soften over time, affecting the overall structure of the hanger. The reinforcing rod improves the structural strength of the main rod 1, thereby ensuring the stability of the overall structure of the hanger. The reinforcing rod is also covered within the insulation layer of the main rod 1.

[0048] The first mounting plate 301 and the support plate 302 are formed together, the second mounting plate 402, the elastic connecting plate 401, and the adjusting plate 404 are formed as one piece, and the pressure plate 408, the clamping block 407, and the third mounting plate 406 are formed as one piece. This facilitates processing and improves the overall structural strength.

[0049] This fixture facilitates the clamping and removal of steel rings, improving work efficiency. At the same time, it reduces the area of ​​the steel ring surface that is obscured, improves the uniformity of the electroplating layer on the steel ring surface, and enhances the product quality of the steel rings.

[0050] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
