Description

Technical Field

[0001] This utility model relates to the field of engine blade electroplating technology, specifically to an engine blade electroplating support frame. Background Technology

[0002] Aero-engine blades operate under high temperature and pressure environments, requiring excellent corrosion resistance and wear resistance. Therefore, electroplating technology is widely used for blade surface treatment. Electroplating not only improves the surface hardness and durability of blades but also enhances their oxidation resistance and corrosion resistance. Commonly used electroplating materials include metals such as nickel and chromium, which can form a dense protective layer, effectively extending the blade's service life. Furthermore, with the development of aero-engine technology, electroplating processes are constantly being improved to meet higher performance requirements and environmental standards.

[0003] The utility model patent with application number CN201920485428.8 and publication number CN209144297U (hereinafter referred to as "Prior Art 1") discloses an electroplating bracket for an aero-engine compressor rotor blade used in electroplating equipment. The bracket includes at least one electroplating unit. The electroplating unit includes two parallel horizontal bars and two vertical bars vertically connected between the two horizontal bars. The upper edge of each horizontal bar is used to engage the weight reduction groove of the rotor blade. Several elastic elements are uniformly fixed to the lower edge of each horizontal bar. Each elastic element is vertically arranged, and its free end is used to hold the tip of the blade. The elastic elements and the corresponding lower horizontal bars cooperate to hold the blade, so that the blade is fixed and electroplated. The elastic elements, vertical bars and horizontal bars are all conductive.

[0004] The specification of prior art 1 discloses an electroplating bracket for an aero-engine compressor rotor blade used in an electroplating equipment. In use, the rotor blade is clamped to keep it upright during the electroplating process, so that the area of ​​the blade to be electroplated can be completely electroplated. However, in actual applications, the blade is fixed by only the elastic element, which causes the blade to be unstablely installed on the bracket, resulting in the blade falling off the bracket and affecting the electroplating of the blade. Summary of the Invention

[0005] This utility model provides an electroplating support frame for engine blades, aiming to solve the problem that the existing blade electroplating support frame is unstable because it only supports the blades through elastic elements.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An electroplating support frame for engine blades includes a mounting assembly and a traction assembly. The mounting assembly is used to fix the blade body, and the traction assembly is used to traction the mounting assembly.

[0008] The installation components include a frame and a clamping structure. The frame is used to install in the electrolytic cell and is rotatably connected to the electrolytic cell. The frame has several installation areas, each of which is used to install a blade body. There are several sets of clamping structures, each set of clamping structures is used to clamp a blade body, and each set of clamping structures is used to install in an installation area.

[0009] The traction assembly includes a first winding device and a first motor. Both the first motor and the first winding device are mounted on the electrolytic cell. The first winding device is fixedly connected to the output shaft of the first motor. A first rope is wound on the first winding device. One end of the first rope is fixedly connected to the bottom of the frame, and the other end is wound on the first winding device and fixedly connected to the first winding device.

[0010] Furthermore, the frame is slidably engaged with the electrolytic cell via a sliding assembly.

[0011] Furthermore, the sliding assembly includes a waist-shaped groove, a connecting rod, and a sliding block. The waist-shaped groove is provided on both sides of the electrolytic cell. The connecting rod is set on the frame. The sliding block is slidably installed inside the waist-shaped groove. The connecting rod and the sliding block are rotatably connected.

[0012] Furthermore, the traction assembly also includes a traction slide, a second motor, and a second cable reel. The traction slide is located on one side of the electrolytic cell. The second motor is mounted on the ground, and a shaft is provided at the end of the second motor. The shaft is rotatably connected to the traction slide. The second cable reel is fixedly mounted on the shaft, and a second rope is wound on the second cable reel. One end of the second rope is connected to the top of the frame, and the other end is fixedly connected to the second cable reel. After the first rope and the second rope are taut, the position of the frame is fixed.

[0013] Furthermore, the sliding assembly also includes two limiting rails, which are arranged on both sides of the traction slide. The sliding area of ​​the traction slide is connected to the sliding area on the waist-shaped slide groove, and the sliding block is used to slide in the limiting rails.

[0014] Furthermore, connecting plates are provided on both sides of the limiting track, and the rotating shaft is rotatably connected to the connecting plates.

[0015] Furthermore, the clamping structure includes a mounting plate, a top block, and a screw. Each mounting area has two mounting plates, and the screw is threadedly connected to one of the two mounting plates. A top block is provided at the end of the screw, and a top block is also provided on the mounting plate. The two top blocks in the same mounting area are arranged opposite each other, and the two opposing top blocks are used to clamp the blade body.

[0016] Furthermore, a handle is provided on the frame, and the end of the second rope is fixedly connected to the handle.

[0017] Furthermore, a rotating part is installed at the end of the screw away from the top block.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model mainly includes an installation component and a traction component. In actual use, the operator controls the first motor to rotate, which in turn drives the first winding device to rotate. The first winding device winds the first rope. Since the frame is installed in the electrolytic cell, when the first rope is wound up, it pulls the frame, causing it to rotate in the electrolytic cell until it is raised. Then, the operator uses a clamping structure to clamp the blade body, ensuring that one blade body is installed in each installation area. After installation, the operator controls the first motor to rotate in the opposite direction. At this time, the first motor drives the first winding device to rotate in the opposite direction, releasing the first rope. The frame rotates towards the bottom of the electrolytic cell under the influence of gravity until all blade bodies are inside the electrolytic cell. At this point, the electrolyte inside the electrolytic cell completely immerses all blade bodies, finally completing the electroplating of the blade bodies. The advantage of this design is that the traction component rotates the frame, making it easier to install the blade bodies. At the same time, the clamping structure can fix the blade bodies, making them more stable during electroplating. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the embodiments. The described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention.

[0026] Please see Figure 1-3 As shown, this embodiment discloses an electroplating support frame for engine blades, including an installation component and a traction component. The installation component is used to fix the blade body 104, and the traction component is used to traction the installation component.

[0027] The installation components include a frame 101 and a clamping structure. The frame 101 is used to install in the electrolytic cell 102 and is rotatably connected to the electrolytic cell 102. The frame 101 has several installation areas 103. Each installation area 103 is used to install a blade body 104. There are several sets of clamping structures. Each set of clamping structures is used to clamp a blade body 104, and each set of clamping structures is used to install in an installation area 103.

[0028] The traction assembly includes a first winding reel 105 and a first motor 106. Both the first motor 106 and the first winding reel 105 are mounted on the electrolytic cell 102. The first winding reel 105 is fixedly connected to the output shaft of the first motor 106. A first rope 107 is wound on the first winding reel 105. One end of the first rope 107 is fixedly connected to the bottom of the frame 101, and the other end is wound on the first winding reel 105 and fixedly connected to the first winding reel 105.

[0029] This utility model mainly includes an installation component and a traction component. In actual use, the operator controls the first motor 106 to rotate. After the first motor 106 rotates, it drives the first winding device 105 to rotate. After the first winding device 105 rotates, it winds the first rope 107. Since the frame 101 is rotatably installed in the electrolytic cell 102, when the first rope 107 is wound up, it pulls the frame 101, causing the frame 101 to rotate in the electrolytic cell 102 until the frame 101 is raised. Then, the operator clamps the blade body 104 using the clamping structure, so that one blade body 104 is installed in each installation area 103. After installation, the operator controls the first motor 106 to rotate in the opposite direction. When the first motor 106 drives the first winding device 105 to reverse, the first winding device 105 releases the first rope 107, and the frame 101 rotates towards the bottom of the electrolytic cell 102 under the action of gravity until all the blade bodies 104 are inside the electrolytic cell 102. At this time, the electrolyte inside the electrolytic cell 102 completely soaks all the blade bodies 104, and finally the electroplating of the blade bodies 104 is completed. The advantage of this setting is that the frame 101 is rotated by the traction component, making it easier to install the blade bodies 104. At the same time, the clamping structure can fix the blade bodies 104, making the blade bodies 104 more stable during electroplating.

[0030] In some embodiments, the frame 101 is slidably engaged with the electrolytic cell 102 via a sliding component.

[0031] In actual use, the purpose of setting up the sliding component is to limit the sliding of the frame 101, so that the frame 101 is more stable and smooth during the sliding process.

[0032] In some embodiments, the sliding assembly includes a waist-shaped groove 108, a connecting rod 109, and a sliding block 110. The waist-shaped groove 108 is provided on both sides of the electrolytic cell 102. The connecting rod 109 is provided on the frame 101. The sliding block 110 is slidably installed inside the waist-shaped groove 108. The connecting rod 109 and the sliding block 110 are rotatably connected.

[0033] In actual use, the traction component pulls the frame 101 to fix its position. When the first rope 107 pulls the frame 101, the frame 101 drives the connecting rod 109 to rotate on the sliding block 110.

[0034] In some embodiments, the traction assembly further includes a traction slide 111, a second motor 112, and a second cable reel 113. The traction slide 111 is disposed on one side of the electrolytic cell 102. The second motor 112 is mounted on the ground. A rotating shaft is provided at the end of the second motor 112 and is rotatably connected to the traction slide 111. The second cable reel 113 is fixedly mounted on the rotating shaft. A second rope 114 is wound on the second cable reel 113. One end of the second rope 114 is connected to the top of the frame 101, and the other end is fixedly connected to the second cable reel 113. After the first rope 107 and the second rope 114 are taut, the position of the frame 101 is fixed.

[0035] In actual use, due to the relatively high height of the electrolytic cell 102, it is inconvenient for workers to install the blade body 104. Therefore, a traction slide 111 is set up. When the frame 101 is pulled up by the first rope 107, the second motor 112 rotates synchronously with the first motor 106. The second motor 112 controls the second winding device 113 to rotate, and the second winding device 113 winds up the second rope 114. The second rope 114 pulls the frame 101 to slide inside the waist-shaped slide groove 108. At this time, the sliding block 110 slides in conjunction with the waist-shaped slide groove 108, and the second rope 11... 4. The first rope 107 is kept taut at all times. The first motor 106 and the second motor 112 rotate at the same speed. The frame 101 slides from the waist-shaped slide groove 108 onto the traction slide 111. When the frame 101 moves to the lowest point of the traction slide 111, the operator fixes and clamps the blade body 104. Then, the frame 101 is reset by the rotation of the first motor 106 and the second motor 112. The advantage of this setting is that the frame 101 is at the lowest point under the action of the traction device, which makes it easier for the operator to install the blade body 104.

[0036] In some embodiments, the sliding assembly further includes two limiting rails 115, which are disposed on both sides of the traction slide 111. The sliding area of ​​the traction slide 111 is connected to the sliding area on the waist-shaped slide groove 108. The sliding block 110 is used to slide in the limiting rails 115.

[0037] In actual use, the limiting track 115 limits the lateral sliding of the sliding block 110, making the sliding block 110 more stable when sliding on the traction slide 111.

[0038] In some embodiments, connecting plates 116 are provided on both sides of the limiting track 115, and the rotating shaft is rotatably connected to the connecting plates 116.

[0039] In actual use, the purpose of setting the connecting plate 116 is to install the rotating shaft, and the two ends of the rotating shaft are rotatably connected to the two connecting plates 116 respectively.

[0040] In some embodiments, the clamping structure includes a mounting plate 117, a top block 118, and a screw 119. Each mounting area 103 has two mounting plates 117 inside, and the screw 119 is threadedly connected to one of the two mounting plates 117. The end of the screw 119 is provided with a top block 118, and the mounting plate 117 is also provided with a top block 118. The two top blocks 118 inside the same mounting area 103 are arranged opposite each other, and the two opposing top blocks 118 are used to clamp the blade body 104.

[0041] As an optional implementation, in this embodiment, there are six installation areas 103, arranged in groups of three. Two groups of installation areas 103 are longitudinally arranged on the frame 101. Each of these three installation areas 103 has five mounting plates 117. The first and second installation areas 103 each have two mounting plates 117, while the third installation area 103 has one mounting plate 117. The left mounting plate 117 of the first installation area 103 is threadedly connected to a screw 119, with a top block 118 at the end of the screw 119. The right mounting plate 117 is fixedly connected to the top block 118. The left mounting plate 117 of the second installation area 103... A top block 118 is fixedly installed on the mounting plate 117. Two screws 119 are threadedly connected to the mounting plate 117 on the right side. The ends of the two screws 119 are provided with top blocks 118. The top block 118 on one screw 119 is located in the first mounting area 103, and the top block 118 on the other screw 119 is located in the third mounting area 103. The third mounting area 103 is located on the mounting plate 117 on the right side, and the top blocks 118 are fixedly connected to it. In actual use, when it is necessary to clamp the blade body 104, the bottom of the blade body 104 has a clamping recess. After rotating the screws 119, the top blocks 118 on the two mounting plates 117 clamp the blade body 104.

[0042] In some embodiments, a handle 120 is provided on the frame 101, and the end of the second rope 114 is fixedly connected to the handle 120.

[0043] In actual use, the purpose of setting handle 120 is to facilitate the installation of the second rope 114.

[0044] In some embodiments, a rotating part 121 is installed at the end of the screw 119 away from the top block 118.

[0045] In actual use, the purpose of setting the rotating part 121 is to facilitate the operator to rotate the screw 119.

[0046] In some embodiments, a rotating roller is provided at the connection between the traction slide 111 and the electrolytic cell 102, and the frame 101 is used to contact the rotating roller.
