Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, and in particular to an electroplating device for engine bearing bushings. Background Technology

[0002] The engine bearing bushing electroplating device is a specialized equipment system used to electroplat the surface of the engine's core component—the bearing bushing (a sleeve-like part that reduces bearing friction, provides positioning support, and buffers vibration). Its core function is to deposit one or more layers of metals with specific properties (such as hard chrome, nickel-phosphorus alloy, copper alloy, etc.) on the surface of the bushing substrate through electrochemical principles. This improves the bushing's wear resistance, corrosion resistance, dimensional repair capability, or surface hardness, thereby extending the service life of the engine bearing assembly and ensuring the engine's operational stability.

[0003] Existing engine bearing bushing electroplating equipment typically places the bearing bushing into an electroplating tank after being clamped by a fixture, and then electroplats it with an electroplating solution. However, the clamping efficiency of the fixture is low, and the loading and unloading process is cumbersome, which reduces the electroplating efficiency of the bearing bushing. Utility Model Content

[0004] The purpose of this invention is to provide an electroplating device for engine bearing bushings, which solves the problems of low clamping efficiency of existing engine bearing bushing electroplating devices, cumbersome loading and unloading processes, and thus reduced electroplating efficiency.

[0005] To achieve the above objectives, an electroplating device for engine bearing bushings is provided, comprising: an electroplating tank, a support leg fixedly connected to the bottom of the electroplating tank, a support rod fixedly connected to the top of the electroplating tank, a top plate fixedly connected to the top of the support rod, a servo motor fixedly installed on the top of the top plate on the right side, a lead screw fixedly connected to the output end of the servo motor via a coupling, and a lifting block movably connected to the outer wall of the lead screw and the support rod to facilitate the lifting and lowering of the basket, thereby facilitating the electroplating and unloading of the bearing bushings;

[0006] An installation plate is fixedly connected to the inner side of the two lifting blocks. A drive motor is fixedly installed on the top of the installation plate. A vertical rod is fixedly connected to the output end of the drive motor via a coupling. An insert is provided at the bottom end of the vertical rod. A sleeve is fitted on the outer wall of the insert. A placement basket is fixedly connected to the bottom end of the sleeve, which facilitates the installation and disassembly of the placement basket, thereby facilitating the removal of the bearing bushing.

[0007] According to the aforementioned electroplating device for engine bearing bushings, a second drive motor is fixedly installed on one side of the electroplating tank, and a rotating shaft is fixedly connected to the output end of the second drive motor via a coupling. A stirring rod is fixedly connected to the outer wall of the rotating shaft, thereby improving the electroplating effect of the bearing bushing.

[0008] According to the aforementioned electroplating device for engine bearing bushings, a controller is provided on the front side of the electroplating tank, and the servo motor, drive motor one, and drive motor two are all electrically connected to the controller.

[0009] According to the aforementioned electroplating device for engine bearing bushings, a screw hole is provided at the top center of the lifting block on the right side. The inner wall of the screw hole and the outer wall of the lead screw are both provided with threads. The lead screw and the screw hole are engaged with each other through threads, which facilitates the lifting of the lifting block and the basket.

[0010] According to the aforementioned electroplating device for engine bearing bushings, each of the lifting blocks has a guide hole at its top, and the lifting block is slidably connected to the outer wall of the support rod through the guide hole, which facilitates the limiting of the lifting block.

[0011] According to the aforementioned electroplating device for engine bearing bushings, a rotating shaft seat is fixedly installed on the top of the electroplating tank, and the bottom end of the lead screw is rotatably connected to the rotating shaft seat to facilitate the rotation of the lead screw.

[0012] According to the aforementioned electroplating device for engine bearing bushings, the shape and size of the insert block are matched with the shape and size of the sleeve, and the insert block and the sleeve are movably connected to facilitate the installation of the basket.

[0013] According to the aforementioned electroplating device for engine bearing bushings, both the insert and the sleeve have positioning holes on their sides, and the two positioning holes are connected by fixing bolts and nuts, which facilitates the installation and disassembly of the basket, thereby facilitating the removal of the bearing bushing.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. This engine bearing bushing electroplating device uses a basket to hold the bearing bushings to be electroplated. Simultaneously, a servo motor drives the lead screw to rotate, which in turn drives the lifting block to rise and fall, thus facilitating the raising and lowering of the basket. The output end of the drive motor is fixedly connected to a vertical rod and an insert block. The bottom end of the insert block is movably connected to a sleeve. The sleeve and the insert block are connected by fixing bolts and nuts, which facilitates the installation and removal of the basket and the loading and unloading of the bearing bushings.

[0016] 2. The engine bearing bushing electroplating device can drive the vertical rod and sleeve to rotate via a drive motor 1, which facilitates the rotation of the basket. At the same time, the drive motor 2 can drive the rotating shaft and stirring rod to rotate, so that the electroplating solution in the electroplating tank is always in a flowing state. This facilitates full contact between the bearing bushing in the basket and the electroplating solution in the electroplating tank, thereby improving the electroplating effect of the bearing bushing.

The servo motor 6 can drive the lead screw 7 to rotate, thereby driving the lifting block 9 and the placement basket 18 to rise and fall.

[0027] Two lifting blocks 9 are fixedly connected to the inner side of the mounting plate 12. The top of the mounting plate 12 is fixedly installed with a drive motor 13. The output end of the drive motor 13 is fixedly connected to a vertical rod 14 through a coupling. The bottom end of the vertical rod 14 is provided with an insert block 15.

The sleeve 17 and the insert block 15 are connected by fixing bolts and nuts, which facilitates the installation and disassembly of the placement basket 18, thereby facilitating the removal of the bearing bushing.

[0028] A drive motor 219 is fixedly installed on one side of the electroplating tank 1. The output end of the drive motor 219 is fixedly connected to a rotating shaft 20 via a coupling. A stirring rod 21 is fixedly connected to the outer wall of the rotating shaft 20. The drive motor 219 can drive the rotating shaft 20 and the stirring rod 21 to rotate, thereby making the electroplating solution in the electroplating tank 1 flow, which facilitates full contact between the bearing bush and the electroplating solution.

[0029] A controller 3 is installed on the front of the electroplating tank 1. The servo motor 6, drive motor 13 and drive motor 2 19 are all electrically connected to the controller 3.

[0030] A screw hole 10 is provided at the top center of the right lifting block 9. The inner wall of the screw hole 10 and the outer wall of the lead screw 7 are both provided with threads. The lead screw 7 and the screw hole 10 are engaged with each other through threads.

[0031] Each lifting block 9 has a guide hole 11 on its top. The lifting block 9 is slidably connected to the outer wall of the support rod 4 through the guide hole 11. The support rod 4 can guide and limit the lifting block 9, thereby improving the stability of the lifting block 9 and the basket 18 during the lifting process.

[0032] A rotating shaft seat 8 is fixedly installed on the top of the electroplating tank 1, and the bottom end of the lead screw 7 is rotatably connected to the rotating shaft seat 8 to facilitate the rotation of the lead screw 7.

[0035] Working principle: The bearing sleeve to be electroplated is placed in the placement basket 18. The servo motor 6 drives the lead screw 7 to rotate forward, which in turn drives the lifting block 9 and the placement basket 18 to descend until the bearing sleeve in the placement basket 18 is completely immersed in the electroplating solution in the electroplating tank 1. During the electroplating process of the bearing sleeve, the drive motor 13 drives the vertical rod 14 and the sleeve 17 to rotate, which in turn drives the placement basket 18 to rotate. The drive motor 19 drives the rotating shaft 20 and the stirring rod 21 to rotate, so that the electroplating solution in the electroplating tank 1 is in a flowing state and the bearing sleeve is in full contact with the electroplating solution, thereby improving the electroplating effect of the bearing sleeve. After the electroplating is completed, the servo motor 6 rotates in the reverse direction, driving the lifting block 9 and the placement basket 18 to rise. The fixing bolts and nuts on both sides of the sleeve 17 can be removed to remove the placement basket 18, which facilitates the removal of the bearing sleeve.
