[0143] An elephant-shaped anode support device comprises a base frame and three movable support blocks on the base frame, such as Figure 1 The above is a schematic diagram of the assembly of the structure applied to the crankshaft electroplating production line: the chassis 11 is a chassis welded by channel steel and angle steel, and the upper end is connected to three fixed support blocks, namely, support block I2, crankshaft support block 5, and support block II10, wherein the upper ends of the fixed support blocks of support block I2 and support block II10 are semi-cylindrical curved surface grooves, and the grooves are fully in contact with the non-electroplated cylindrical surface of the crankshaft to achieve positioning and conduction. In addition, the upper end of the chassis is fixedly connected to two slide rails (slide rail I8 and slide rail II9), and the groove clearance of the slide rail I8 and the lower end of the anode support slider I4 (small end pictographic anode support slider) is matched to complete the support and positioning function of the object anode. Similarly, the slide rail II9 and the anode support slider II7 can complete the support and positioning function of another pictographic anode. Pictographic anode pictographic anode I3 and pictographic anode II6 are respectively connected to the small end pictographic anode support slider anode support slider I4 and the large end pictographic anode support slider anode support slider II7 by φ8 bolts (detachable). When designing the bracket, first ensure that the centers of the two pictographic anodes are at the same height after assembly. Then, by adjusting the positions of the anode support slider I4 and the anode support slider II7 on the guide rail, the inner hole of the pictographic anode is concentric with the electroplated outer cylindrical surface corresponding to the crankshaft. Tighten the M8 bolts at the lower ends of the anode support slider I4 and the anode support slider II7 to press against the corresponding slide rail (a φ8 shallow hole can be drilled at the tightening position of the guide rail for quick and accurate positioning). Figure 4 .

[0144] The lower pictographic anode (reference Figure 5 ) is a separate type, and its inner surface diameter is 20 mm larger than the corresponding crankshaft electroplated cylindrical surface, and during installation, it is ensured that the inner surface formed by the two petals of the anode is concentric with the corresponding cylindrical surface of the workpiece.

[0145] The pictographic anode and the support slider are connected by bolts (refer to Figure 6 ), which not only ensures the position accuracy but also makes it removable for electroplating tooling of other parts.

[0146] There is a gap groove between the anode support slider and the slide rail. In addition, a long groove with a width of 8 mm is processed on one side of the slide rail. It cooperates with the M8 bolt under the support slider to complete the anti-falling (the bolt only extends into the side groove half of the depth during sliding) and precise positioning (the bolt is screwed to the inner wall of the side groove of the slide rail to support the slide rail during electroplating). Please refer to Figure 4 .

[0147] Fixed support block support block I2 and support block II10 (reference Figure 7) The upper end is designed as a semi-cylindrical hole-like curved surface, and its arc radius is slightly larger by 0.5 to 1.5 mm than the corresponding non-electroplated cylindrical surface of the workpiece. Firstly, it ensures the automatic centering effect under the action of gravity. Secondly, since the eccentricity of the two electroplated cylindrical surfaces after the crankshaft is processed has a deviation of 2 mm, it is easy for the workpiece to be stuck on both sides of the curved surface instead of falling to the bottom. In addition, the support block II10 can be fixedly connected to the base frame, and the support block I2 can be floatingly connected to the base frame (there can be 2 to 3 mm of movement perpendicular to the axis of the crankshaft). This structure fully solves the positioning problem of electroplating multiple surfaces of crankshaft parts at one time.

[0148] The pictographic anode support structure can solve the one-time electroplating positioning problem of large and complex parts by adding a multi-layer base frame (similar to a multi-layer shelf), adding vertical, left and right, front and back multi-station slide rails and corresponding pictographic anodes.

[0149] The bracket structure design reflects the workpiece-centered design concept, while taking into account the universality of multiple reuse of parts such as slide rails, creating a new approach for the electroplating tooling design of large parts.

[0150] The slide rail structure of the bracket structure design can provide a wide range of adjustment space for the nearly flat separated pictographic anode, and can cooperate with the electroplating process parameters such as current and voltage to better control the coating thickness and electroplating time on the electroplating surface, thereby improving the electroplating quality and reducing the electroplating cost.

[0151] Embodiment 22:

[0152] See also Figures 1 to 10 , a slide rail type pictographic anode support device, the main technical contents include:

[0153] The invention discloses an elegantic anode support device, which is an electroplating process equipment with convenient disassembly and accurate adjustable position, and comprises a base frame, three movable support blocks on the base frame, and an elegantic anode sliding positioning device (a detachable elegantic anode slider, a slider positioning and anti-falling device).

[0154] like Figure 1The above is a schematic diagram of the assembly of the structure applied to the crankshaft electroplating production line: the chassis 11 is a chassis welded by channel steel and angle steel, and the upper end is connected to three fixed support blocks, namely, support block I2, crankshaft support block 5, and support block II10, wherein the upper ends of the fixed support blocks of support block I2 and support block II10 are semi-cylindrical curved surface grooves, and the grooves are fully in contact with the non-electroplated cylindrical surface of the crankshaft to achieve positioning and conduction. In addition, the upper end of the chassis is fixedly connected to two slide rails (slide rail I8 and slide rail II9), and the groove clearance of the slide rail I8 and the lower end of the anode support slider I4 (small end pictographic anode support slider) is matched to complete the support and positioning function of the object anode. Similarly, the slide rail II9 and the anode support slider II7 can complete the support and positioning function of another pictographic anode. Pictographic anode pictographic anode I3 and pictographic anode II6 are respectively connected to the small end pictographic anode support slider anode support slider I4 and the large end pictographic anode support slider anode support slider II7 by φ8 bolts (detachable). When designing the bracket, first ensure that the centers of the two pictographic anodes are at the same height after assembly. Then, by adjusting the positions of the anode support slider I4 and the anode support slider II7 on the guide rail, the inner hole of the pictographic anode is concentric with the electroplated outer cylindrical surface corresponding to the crankshaft. Tighten the M8 bolts at the lower ends of the anode support slider I4 and the anode support slider II7 to press against the corresponding slide rail (a φ8 shallow hole can be drilled at the tightening position of the guide rail for quick and accurate positioning). Figure 4 .

[0155] The design of the pictographic anode support structure first designs the positioning state of the crankshaft in space, then designs the pictographic anode, then designs the supporting slider and positioning block, then designs the slide rail, and finally designs the base frame. The center lines of each channel steel (angle steel) of the base frame correspond to the center lines of the three fixing blocks and two slide rails (a total of 4 channel steels and 1 angle steel), refer to Figure 8 and Fig. 9 During manufacturing and installation, the shape and position tolerance of the chassis and the flatness of the upper surface must be ensured first, because the chassis is the positioning basis of the entire bracket structure.

[0156] The design of the pictographic anode support structure has a total of 3 fixed support blocks. Because the eccentricity of the two electroplated cylindrical surfaces of different workpieces after crankshaft processing is 2 mm, it is easy for some workpieces to get stuck on both sides of the curved surface and not fall to the bottom. The following is the connection plan for the chassis: support block II10 (two M 8 threaded connection) is fixedly connected to the chassis, and 8×10mm (two places) rectangular holes are processed at the connection between the support block I2 and the chassis on the upper surface of the chassis, and the chassis and the support block I2 are loosely connected with bolts: a countersunk threaded hole is processed at the bottom of the support block I2, which is tightened with the hexagonal headless M8 bolt, and a T-type 13mm socket wrench is used to assemble the anti-loosening washer and the M8 thin nut at the countersunk head of the inner hole to tighten the bolt under the support block I2. The bolt extends about 20mm below the support block I2, and two M8 thin nuts are used to connect the hexagonal nuts at the bottom of the chassis. The upper surface of the upper nut is screwed to 0.5-1mm away from the lower surface of the chassis, and the lower nut is tightened with the upper nut to prevent the two nuts from loosening. This ensures that the bolt can move slightly in the rectangular hole of the chassis, thereby ensuring that the support block I2 can have a movement of about 2 mm in the direction perpendicular to the axis of the crankshaft. The crankshaft support block 5 is the support block in the middle of the crankshaft. Because it is in contact with the middle curved surface of the crankshaft, the accuracy of the middle curved surface is relatively low. Therefore, the connection method between the crankshaft support block 5 and the base frame is the same as that of the support block I2. The size of the corresponding rectangular hole should be determined according to the on-site debugging and installation conditions and the consistency of the shape of the middle curved surface of the crankshaft. It is necessary to prevent the middle of the crankshaft from sinking and over-positioning (the crankshaft support block 5 will raise the middle of the workpiece). The inclined surface at the upper end of the crankshaft support block 5 can be used to adjust the vertical position of the middle of the crankshaft. Its function is similar to that of the wedge installed at the bottom of the machine tool. Please refer to Fig.10 .

[0157] The design of the pictographic anode support structure and the on-site commissioning and installation are very important, and the steps are as follows:

[0158] 1) Place the chassis on the platform with the support surface facing upward.

[0159] 2) Arrange the support block I2, crankshaft support block 5, slide rail I8, slide rail II9, support block II10 according to Figure 1 and Figure 3 The corresponding positions are placed on the channel steel (angle steel) corresponding to the bracket, and the symmetry axis of each part should be aligned with the center line of the channel steel (angle steel) as much as possible.

[0160] 3) The fitter presses the crankshaft Figure 1 and Figure 3The position is placed above the support block I2, crankshaft support block 5, slide rail I8, slide rail II9, and support block II10, and the position of each part is further fine-tuned. Then take 4-5 crankshafts to repeat the above steps, and determine the position of the two axis centers of the crankshafts above the slide rail I8 and the slide rail II9 according to the average value of the eccentricity of several crankshafts, and draw the projection line of the center line at the corresponding positions on the slide rails I8, II9 and the chassis, draw the projection line of the symmetry axis line of each part on the chassis, and then remove each part, design the connection position at the marked part of the chassis, compare the support block I2, crankshaft support block 5, slide rail I8, slide rail II9, and support block II10 to determine the position, and drill holes in the chassis with a diameter of φ6.7 (M8 threaded bottom hole size, two places for each piece), and then turn the chassis over to drill the threaded bottom holes corresponding to the support block I2, crankshaft support block 5, slide rail I8, slide rail II9, and support block II10. Finally, the fitter marks, arranges holes and files rectangular holes to install the support block I2 and the crankshaft support block 5, and then expands the φ6.7 hole of the base frame to φ8.2-φ8.3.

[0161] 4) When designing the bracket, first ensure that the centers of the two pictographic anodes are at the same height after assembly. Then, by adjusting the positions of the anode support slider I4 and the anode support slider II7 on the guide rail, make the inner hole of the pictographic anode concentric with the electroplated outer surface corresponding to the crankshaft. Tighten the M8 bolts at the lower ends of the anode support slider I4 and the anode support slider II7 so that they are pressed against the corresponding slide rail (a φ8 shallow hole can be drilled at the tightening position of the guide rail for quick and accurate positioning). Refer to Figure 4 .
