Description

Technical Field

[0001] The utility model relates to the technical field of musical instrument surface treatment, in particular to a musical instrument rack plating device. Background Art

[0002] As an important tool for artistic performance, the aesthetics and durability of musical instruments directly impact the performance and value of the instrument itself. Some components on instruments like trumpets and saxophones undergo electroplating before use. These components are often cylindrical in structure, and surface plating not only enhances the instrument's aesthetics but also its durability. However, existing rack plating devices typically hang the instrument parts to be plated on a plating rack, then place the rack with the parts in a energized plating solution to electroplate the workpieces. For example, a height adjustment device for rack plating, published as CN217173934U, includes a base frame with a guide post secured to a rack. A vertically movable guide member is slidably connected to the guide post, the guide member being equipped with a motor that drives a first gear meshing with the rack. A support post is secured to the guide member, and a support hook is provided to secure the rack. This device facilitates the adjustment of the height of the plating rack during the electroplating process. During the electroplating process, the rack will be placed in the plating solution, and then the energized electrolyte will electroplate the workpiece. However, the electroplating layer obtained by such a stationary plating is poorly uniform, resulting in quality deviations in the workpiece.

[0003] Therefore, it is necessary to develop a musical instrument hanging plating device for the above-mentioned defects. Utility Model Content

[0031] In one embodiment, Figures 1 to 4 As shown, the fixing fixture 4 includes a lifting ring 401, a hanging column 402, and a splint 403. The lifting ring 401 is suspended at the lower end of the hook 322. The lifting ring 401 is fixedly connected to the hanging column 402 as an integrated structure. The lower end of the hanging column 402 is installed on the fixing plate 404. The upper end surface of the fixing plate 404 is provided with a first fixing seat 405. The first fixing seats 405 are evenly distributed at three locations. The first fixing seat 405 is hinged to a first connecting rod 406. The other end of the first connecting rod 406 is hinged to the lower end surface of the splint 403. The upper end surface of the splint 403 is hinged to a second connecting rod 408. The other end of the second connecting rod 408 is hinged to a second fixing seat 407. The upper end surface of the second fixing seat 407 is provided with a sliding plate 409. The sliding plate 409 and the second fixing seat 407 are an integrated structure. The sliding plate 409 passes through the hanging column 402 and slides on the hanging column 402. A plastic plate is bonded to the outside of clamping plate 403. The plate is made of electroplating-grade material, which is both conductive and prevents scratches on the instrument's parts. A baffle 4011 is fixedly mounted on the suspension post 402 at the top of the sliding plate 409. Baffle 4011 is located at the bottom of the suspension ring 401. A spring 4010 is installed between the baffle and sliding plate 409, driving the spring 4010 to move the sliding plate 409 downward.

[0032] In one embodiment, Figures 1 to 4 As shown, the upper end surface of the sliding plate 409 is provided with two hooks to facilitate the removal of the fixing fixture 4 from the musical instrument parts.

[0033] In one embodiment, Figures 1 to 4As shown, the instrument further includes a fan assembly 8, which includes a blower 801, a pipe 802, and an air outlet 803. The blower 801 is mounted on the upper end surface of the support frame 2, and the pipe 802 is connected to the air outlet of the blower 801. The pipe 802 passes through the upper end surface of the support frame 2 and is connected to the air outlet 803. The air outlet 803 is located at the lower end of the support frame 2 and is tilted. The air outlet 803 is directed at the musical instrument parts in time to blow off the residual plating solution on the musical instrument parts, thereby preventing the plating solution from staying on the musical instrument parts for a long time and affecting the quality of the musical instrument parts.

[0034] The operation process of the instrument plating device of the present invention is as follows: the instrument parts to be electroplated are hung on the plating rack 3. According to the size of the instrument parts, the number and fixed positions of the adjustment racks 32 to be installed are selected, and the adjustment racks 32 are fixed to the through holes 313 on both sides of the frame 31 by screws. The instrument parts are then fixed with the fixing fixture 4 and hung on the hooks 322 at the lower ends of the adjustment racks 32. The two hooks on the upper end surface of the sliding plate 409 are pulled upward to compress the spring 4010, and the distance between the clamps 403 on the fixing fixture 4 is reduced, and the fixing fixture 4 is placed in the inner cavity of the instrument parts. The hooks are released, and driven by the spring 4010, the sliding plate 409 slides downward, reducing the distance between the first connecting rod 406 and the second connecting rod 408. The first connecting rod 406 and the second connecting rod 408 are hinged together with the clamps 403, so that the clamps 403 are opened outward and fit against the inner cavity wall of the instrument parts, so that the fixing fixture 4 firmly grasps the instrument parts. A plastic plate is bonded to the outside of the clamping plate 403. The plastic plate is made of electroplating-grade material. It is conductive and increases friction, while also preventing the surface from being too hard and scratching the instrument parts. The clamped instrument parts are hung on the hook 322. The plating rack 3 with the instrument connection is clamped to the support rods 503 at both ends of the fixed block 502 via the hanging feet 311. Limit blocks 504 are installed at both ends of the support rod 503, and the hanging feet 311 are clamped in the limit blocks 504 to prevent shaking during operation. Start the second motor 601, which will drive the screw rod 602 to rotate, causing the crossbeam 7 mounted on the screw rod 602 to move downward. The plating rack 3 is immersed in the electroplating solution. At the same time, start the first motor 501, which will drive the fixed block 502 to rotate, causing the plating rack 3 to rotate accordingly. The instrument parts to be electroplated are immersed in the electroplating solution and fully combine with the electroplating solution. Under the action of the rotation of the plating rack 3, the electroplating solution is prevented from precipitating and affecting the electroplating effect. After electroplating is complete, the second motor 601 is activated, driving the crossbeam 7 upward, freeing the instrument parts from the plating solution. The blower 801 at the top is activated, and the air outlet 803 blows off any residual plating solution from the parts. During this process, the first motor 501 continues to operate, drying the instrument parts on the plating rack 3 as quickly as possible. This prevents the plating solution from remaining on the parts for extended periods, which could affect their quality. After drying, the plating rack 3 is removed and the drying process proceeds to the next step.

[0035] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Reference can be made to the common and similar parts between the various embodiments. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the method description.

[0036] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
