Description

Technical Field

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

[0002] In the electroplating process of diamond wire rings, the fixture is a key tool for carrying and fixing the wire rings to be plated. Its design rationality and ease of use directly affect production efficiency, product quality and the level of production automation.

[0003] Currently, the diamond wire loop electroplating fixture commonly used in the industry typically involves the following steps: First, the diamond wire loops are manually bound together one by one using copper wire to form a ring structure with a fixed wire spacing. Then, the bound rings are fixed and suspended on a cross-shaped iron frame assembled from multiple sheet metal pieces using screws using dovetail clamps. Finally, the entire fixture with the suspended rings is placed on the electroplating machine for subsequent electroplating processing.

[0004] However, the process of manually binding the loops with copper wire is time-consuming, resulting in low overall wire-binding efficiency. Furthermore, during mass production, especially in the electroplating solution environment, the relatively soft copper wire cannot provide sufficient support and isolation, causing adjacent loops to easily stick and squeeze together.

[0005] Based on this, in order to optimize the applicability of existing electroplating fixtures, we propose a diamond toroidal electroplating fixture. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the time-consuming process of manually binding loops with copper wire, and to propose a diamond loop electroplating fixture.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Design a diamond toroidal electroplating fixture, including:

[0009] The tooling rod and the fixing plate fixed below the tooling rod;

[0010] The outer side of the fixed plate has several connection positions, and a limiting block is fixedly installed at the connection position and an inner clamp is movably connected thereto. The limiting block is equipped with a locking structure for locking the inner clamp.

[0011] The inner clamp is rotatably connected to the outer clamp at its bottom, and the diamond ring wire is clamped between the inner clamp and the outer clamp. A fixing structure is also provided between the inner clamp and the outer clamp.

[0012] Furthermore, the fixing plate has a cross-shaped structure;

[0013] Each leg end of the fixing plate is bent downward to form the connection position, wherein at least two positioning rods are fixedly installed on the end face of the connection position, and the inner clamp and the positioning rods pass through each other.

[0014] Furthermore, the locking structure includes a pressure block rotatably connected to one side of the limiting block, a wing bolt passing through the end face of the pressure block, the wing bolt being threadedly connected to the end face of the limiting block, and at least a portion of the pressure block stopping on the outside of the inner clamp.

[0015] Furthermore, the fixing structure includes a locking rod passing through the outer clamp and locking heads and limiting heads fixed at both ends of the locking rod;

[0016] An clearance hole is provided on the end face of the inner clamp for the lock head to pass through. The lock head enters along the clearance hole and stops at the back end of the inner clamp after rotation.

[0017] Furthermore, the lock head has a rectangular structure, and a rotating groove communicating with the clearance hole is provided at the back end of the inner clamp. The lock head can rotate in the rotating groove, and a stop protrusion is formed on the step position between the rotating groove and the clearance hole.

[0018] Furthermore, toothed plates are formed on the opposing surfaces of the inner and outer clamps, with the tips of the two toothed plates facing each other, and the diamond ring wire is clamped in the tooth groove formed by the two toothed plates.

[0019] Furthermore, a rotating sleeve is rotatably connected to the top of the tool rod via a bearing. The bottom of the rotating sleeve has a frustum-shaped surface and an inwardly narrowed opening on its outer side.

[0020] Furthermore, the jig rod and the fixing plate are detachably connected by fasteners.

[0021] The diamond toroidal wire electroplating fixture proposed in this utility model has the following advantages: The electroplating fixture is simple to operate. When clamping the diamond toroidal wire, only the outer clamp needs to be rotated, and the outer and inner clamps are connected by a fixing structure. During clamping, the spacing of the toothed plates ensures the distance between the diamond toroidal wire coils, and the diamond toroidal wire can be quickly clamped simply by rotating the fixing structure. Furthermore, subsequent disassembly is simple, meeting the needs of automated loading and unloading and processing, effectively improving production efficiency, product quality, and yield.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-3 As one embodiment of the present utility model, a diamond toroidal electroplating fixture is disclosed, specifically the fixture includes a jig rod 1 and a fixing plate 2 fixed below the jig rod 1;

[0028] The outer side of the fixed plate 2 has several connection positions 20. A limiting block 3 is fixedly installed at the connection position 20 and an inner clamp 4 is movably connected thereto. The limiting block 3 is equipped with a locking structure 5 for locking the inner clamp 4.

[0029] The inner clamp 4 is rotatably connected to the outer clamp 6 at its bottom, and the diamond ring wire is clamped between the inner clamp 4 and the outer clamp 6. A fixing structure 7 is also provided between the inner clamp 4 and the outer clamp 6.

[0030] In some embodiments, the fixing plate 2 in this invention has a cross-shaped structure;

[0031] Each leg end of the fixing plate 2 is bent downward to form the connection position 20. In this embodiment, there are four connection positions 20, which can realize the installation connection of four inner clips 4. At least two positioning rods 21 are fixedly installed on the end face of the connection position 20, and the inner clips 4 and the positioning rods 21 pass through each other.

[0032] When installing the inner clamp 4 and the outer clamp 6, first align the two holes on the inner clamp 4 with the two positioning rods 21 and insert them to achieve the installation and positioning of the inner clamp 4. Then, the inner clamp 4 can be clamped and fixed by the locking structure 5, thus quickly completing the fixing of the inner clamp 4.

[0033] Preferably, in this embodiment, the locking structure 5 includes a pressure block 51 rotatably connected to one side of the limiting block 3, a wing bolt 52 is provided on the end face of the pressure block 51, the wing bolt 52 is threadedly connected to the end face of the limiting block 3, and at least a portion of the pressure block 51 stops on the outside of the inner clamp 4.

[0034] When fixing the inner clamp 4, rotate the pressure block 51 so that its bottom stops on the outside of the inner clamp 4. Then, lock and fix the pressure block 51 by the threaded connection of the wing bolt 52 and the limiting block 3. Then, clamp and fix the inner clamp 4 by the pressure block 51. This completes the installation of the entire inner clamp 4. Conversely, if it is necessary to disassemble the inner clamp 4 and the outer clamp 6, simply loosen the wing bolt 52, rotate the pressure block 51 in the opposite direction, and then pull the inner clamp 4 outward to remove it.

[0035] In a further embodiment, the fixing structure 7 in this embodiment includes a locking rod 71 passing through the outer clamp 6 and a locking head 72 and a limiting head 73 fixed at both ends of the locking rod 71;

[0036] An obstacle hole 41 is provided on the end face of the inner clamp 4 for the lock head 72 to pass through. The lock head 72 enters along the obstacle hole 41 and stops at the back end of the inner clamp 4 after rotation.

[0037] It should be noted that the lock head 72 in this embodiment has a rectangular structure. A rotating groove 42 communicating with the clearance hole 41 is also provided at the back end of the inner clamp 4. The lock head 72 can rotate in the rotating groove 42. A stop protrusion 43 is also formed on the step position between the rotating groove 42 and the clearance hole 41.

[0038] Specifically, when it is necessary to lock the outer clamp 6 onto the inner clamp 4, first rotate the outer clamp 6 to make it contact the inner clamp 4, and then hold the locking rod 71 to insert the lock head 72 along the clearance hole 41. Of course, the clearance hole 41 described in this embodiment should also be configured as a rectangular hole.

[0039] After the lock head 72 passes through the aforementioned clearance hole 41, the lock rod 71 can be rotated to make the lock head 72 rotate inside the rotating groove 42. After rotating ninety degrees, the lock head 72 is placed above the stop protrusion 43 to complete the positioning of the lock head 72. At this time, the connection and positioning of the inner clamp 4 and the outer clamp 6 can be completed.

[0040] Of course, considering that in order to maintain a tight connection between the inner clamp 4 and the outer clamp 6, the limiting head 73 described in this embodiment can be set as a nut, and the nut is threadedly connected to the locking rod 71. In a preferred embodiment, a spring can also be sleeved on the outside of the locking rod 71, and the two ends of the spring abut against the outer wall between the limiting head 73 and the outer clamp 6, so as to improve the connection stability of the outer clamp 6 during clamping.

[0041] In some embodiments, toothed plate portions 44 are formed on the opposing surfaces of the inner clamp 4 and the outer clamp 6 in this invention. The tips of the two toothed plate portions 44 face each other, and the diamond wire loop is clamped in the tooth groove formed by the two toothed plate portions 44. That is, when the inner clamp 4 and the outer clamp 6 are closed, the tips of the two toothed plate portions 44 face each other, and the tooth groove between the two toothed plate portions 44 is used to place the diamond wire loop. This ensures the separation and positioning of each turn of the diamond wire loop, thereby improving the stability of subsequent electroplating. The spacing of the toothed plate portions 44 ensures the distance between the diamond wire loop coils.

[0042] Optionally, in this embodiment, a rotating sleeve 8 is rotatably connected to the top of the jig rod 1 via a bearing. The bottom of the rotating sleeve 8 has a frustum-shaped surface 81 and an inwardly narrowed opening 82 on its outer side. Specifically, in this embodiment, a stepped position is formed at the top of the jig rod 1, and the rotating sleeve 8 is fitted and stopped on the stepped position. Then, a bearing is used to stop the rotating sleeve 8 and the top of the jig rod 1. A retaining spring and a limiting nut can also be configured to stop the position of the bearing to prevent the bearing from moving.

[0043] In this embodiment, the use of a rotating sleeve 8 allows the entire jig rod 1 to rotate freely. The rotating sleeve 8, with its frustum-shaped surface 81 and inwardly narrowed opening 82, ensures that the diamond toroidal electroplating jig is securely placed on the support plate during production and meets the requirements for automated material handling and clamping.

[0044] It should be noted that the tool rod 1 and the fixing plate 2 in this utility model are detachably connected by fasteners. Of course, the fasteners can be bolts, which can lock the fixing plate 2 and the tool rod 1 together, thereby improving the overall detachability and ease of maintenance.

[0045] In summary, the electroplating fixture of this invention is simple to operate. When fastening diamond wire loops, only the outer clamp 6 needs to be rotated, and the outer clamp 6 and inner clamp 4 are connected by the fixing structure 7. During clamping, the spacing of the toothed plate portion 44 ensures the distance between the diamond wire loop coils, and the diamond wire loops can be quickly clamped by simply rotating the fixing structure 7. At the same time, subsequent disassembly is simple, meeting the needs of automated loading and unloading and processing in the later stages, effectively improving production efficiency, product quality, and production yield.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
