Description

Technical Field

[0001] This utility model relates to the field of rack plating fixtures, specifically a rack plating fixture with stable transmission. Background Technology

[0002] Rack plating is a process in which the workpiece is clamped on a rack and the rack and workpiece are immersed together in an electroplating solution for electroplating. Since the electroplating process involves steps such as electroplating, degreasing, cleaning, etc., the rack plating system is used to move the rack between multiple solution pools to transfer the rack and workpiece to each workstation where the operation needs to be performed.

[0003] According to a published application for a stable plating fixture (publication number: CN216550795U), the aforementioned application uses multiple clamping elements to clamp the mounting hooks in both directions, increasing the friction between the mounting hooks and the crossbar. This reduces the probability that the square frame will rotate on the crossbar due to inertia when the crossbar moves horizontally, and also reduces the probability that the square frame will sway and shake when the crossbar moves. This makes the horizontal movement and transmission of the square frame and the plating parts more stable, reducing the probability that the plating layer will be scratched due to mutual friction caused by swaying between the plating parts, or that the plating parts will fall off the hooks due to swaying.

[0004] However, the clamping component relies on the elastic force of the compression spring to push the mounting hook and the crossbar together. The compression spring is in a state of compression for a long time, and its elastic force is easily reduced due to metal fatigue. Especially under the inertial impact of frequent start-stop of the plating system, the elastic force decreases faster, which will directly reduce the tightness between the mounting hook and the crossbar, resulting in reduced frictional resistance and decreased stability. Utility Model Content

[0005] The purpose of this invention is to provide a plating fixture with stable transmission to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stable plating fixture, comprising a square frame, a groove at the top of the square frame, multiple arrays of horizontal bars fixedly connected to the inner wall of the square frame, multiple arrays of hooks fixedly connected to both sides of the horizontal bars, a mounting hook one and a mounting hook two hinged to the top of the square frame, a support assembly provided between the mounting hook one and the mounting hook two, the support assembly including a traction plate, two sets of traction plates, the two sets of traction plates respectively hinged to the opposite back sides of the mounting hook one and the mounting hook two, through holes opened on the side walls of the two sets of traction plates, and connecting rods inserted into the through holes, protrusions fixedly connected to both ends of the connecting rods, through holes opened on the surfaces of the two sets of protrusions, a lead screw one threadedly connected to the through hole of one set of protrusions, one end of the lead screw one rotatably connected to the inner wall of the groove, and a rotating wheel one fixedly connected to the other end of the lead screw one.

[0012] Compared with the prior art, this utility model provides a plating fixture with stable transmission, which has the following beneficial effects:

[0013] 1.

Detailed Implementation

[0019] like Figures 1-3 As shown, this utility model provides a technical solution: a stable plating fixture, including a square frame 1, a groove 11 on the top of the square frame 1, multiple arrays of horizontal bars 2 fixedly connected to the inner wall of the square frame 1, multiple arrays of hooks 21 fixedly connected to both sides of the horizontal bars 2, and a first mounting hook 3 and a second mounting hook 4 hinged to the top of the square frame 1. The opening directions of the first mounting hook 3 and the second mounting hook 4 are opposite. The first mounting hook 3 and the second mounting hook 4 are used to install the square frame 1 on the rod of the plating system. The opposite opening directions of the first mounting hook 3 and the second mounting hook 4 can clamp the rod from both sides, avoiding tilting or falling off caused by installation on one side, and initially improving the installation stability.

[0020] A support assembly 5 is provided between mounting hook 3 and mounting hook 4. The support assembly 5 includes a traction plate 51. There are two sets of traction plates 51. The two sets of traction plates 51 are respectively hinged to the opposite back sides of mounting hook 3 and mounting hook 4. The side walls of the two sets of traction plates 51 are provided with through holes, and connecting rods 52 are inserted into the through holes. Both ends of the connecting rods 52 are fixedly connected to protrusions 53. Through holes are provided on the surfaces of the two sets of protrusions 53. A lead screw 55 is threadedly connected to the through hole of one set of protrusions 53. One end of the lead screw 55 is rotatably connected to the inner wall of the groove 11, and the other end of the lead screw 55 is fixedly connected to a rotating wheel 56. A guide rod 54 is slidably connected to the through hole of the other set of protrusions 53. The bottom end of the guide rod 54 is fixedly connected to the inner wall of the groove 11. By rotating the first wheel 56, the first screw 55 rotates. Because it is threadedly connected to one set of protrusions 53, the first guide rod 54 restricts the movement direction of the other set of protrusions 53 to avoid deviation and ensure a smooth adjustment process. As a result, the two sets of protrusions 53 pull the traction plate 51 through the connecting rod 52, thereby adjusting the opening angle of the first mounting hook 3 and the second mounting hook 4, so that they fit tightly against the rod of the plating system.

[0021] A clamping assembly 6 is provided at the top of the square frame 1. The clamping assembly 6 includes a lifting plate 61, and a bonding plate 62 is fixedly connected to the surface of the lifting plate 61. Four sets of through holes are opened on the surface of the lifting plate 61, and guide rods 63 are slidably connected to each through hole. The guide rods 63 are fixedly connected to the top of the square frame 1. A lead screw 64 is rotatably connected to the top of the square frame 1. The lead screw 64 passes through and is rotatably connected to the surface of the lifting plate 61. A rotating wheel 65 is fixedly connected to the top of the lead screw 64. By rotating the rotating wheel 65, the lead screw 64 rotates, driving the lifting plate 61 to move up and down along the guide rods 63. The bonding plate 62 on the surface of the lifting plate 61 rises and falls together, which can fit against the bottom of the outer wall of the rod of the plating system. The mechanical clamping restricts the vertical displacement of the hanger and avoids shaking or deviation caused by vibration during transmission.

[0022] In this invention, during use, the first rotating wheel 56 drives the lead screw 55 to rotate according to the actual size of the plating system rod. Since the lead screw 55 is threadedly connected to a set of protrusions 53, and the other set of protrusions 53 can only move in a straight line under the restriction of the guide rod 54, the two sets of protrusions 53 will synchronously pull the two sets of traction plates 51 through the connecting rod 52, thereby causing the mounting hook 3 and mounting hook 4 to rotate around the hinge point, adjusting the opening size to match the rod diameter. After the opening angles of mounting hook 3 and mounting hook 4 are matched, they are inserted from both sides of the rod, using the opposite opening directions to clamp the rod from both sides, completing the initial fixation. At this time, the rotating wheel 56 is rotated again to further tighten the mounting hook 3 and mounting hook 4, so that their inner walls are tightly attached to the surface of the rod. The mechanical pulling force of the support component 5 ensures that there is no loose gap between the mounting hook and the rod, improving installation stability.

[0023] Then, rotating wheel 65 drives screw 64 to rotate. Under the threaded transmission of screw 64 and the limiting action of guide rod 63, lifting plate 61 rises vertically until the bonding plate 62 on the surface of lifting plate 61 is tightly attached to the bottom of the outer wall of the plating system rod. Through the mechanical abutment between the bonding plate 62 and the rod, the hanger is supported from below, limiting the vertical displacement of the hanger during transmission and preventing shaking or deviation caused by equipment vibration or transmission bumps.

[0024] After installation and fixing, the workpieces to be electroplated are sequentially hung on the hooks 21 on both sides of the crossbar 2. When the plating system is running, the first installation hook 3 and the second installation hook 4 stably clamp the bar from both sides, the support component 5 provides a continuous tightening force to prevent the installation hooks from loosening, and the clamping component 6 restricts the up-and-down swaying of the hanger from the bottom. The three work together to achieve the stability of the hanger during the transmission process, effectively ensuring the smooth progress of the electroplating operation and the electroplating quality of the workpieces.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
