Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrophoresis component production, and in particular to a hanger for electrophoresis component production. Background Technology
[0002] Electrophoretic coating parts production refers to the manufacturing process of using electrophoretic coating technology to treat metal or conductive parts for corrosion and rust prevention. This process is widely used in the surface treatment of metal parts in industries such as automobiles, home appliances, hardware, and electronics.
[0003] The current technology for producing electrophoretic parts uses fixed hangers, which have the disadvantages of large footprint and the need to match various models of hangers according to different product sizes, resulting in a large variety of prefabricated hangers. At the same time, the current electrophoretic part hangers mostly use two-end slot-type disassembly hangers, which are difficult to disassemble and cause paint to accumulate at both ends during electrophoretic coating, resulting in paint contamination.
[0004] Therefore, a fixture for the production of electrophoretic components is proposed to solve the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a hanger for the production of electrophoretic parts. By setting a sleeve connection between the main rod and the auxiliary rod of the hanger, the conductivity problem of the detachable main rod and auxiliary rod of the hanger is solved. At the same time, the workload of hanger maintenance is reduced. It is suitable for most electrophoretic parts of various sizes, occupies little space, has low investment cost, is easy to maintain, and is easy to pick up and can be operated with one hand.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A fixture for producing electrophoretic components includes a vertically arranged main rod.
[0008] The main rod of the hanging device has several connecting blocks welded on its side from bottom to top;
[0009] Each of the connecting blocks has a U-shaped fork welded to its side;
[0010] It also includes several horizontally arranged hanger sub-rods, and each hanger sub-rod has two sleeves welded to its side;
[0011] A gap is formed between the two sleeves, and a sleeve hole is opened at the bottom of the sleeve. The two sleeves are sleeved on the outside of one of the U-shaped forks through the sleeve hole.
[0012] The top of the main rod of the hanger is fixedly equipped with a hoisting and locking structure, and a crossbeam is provided above the hoisting and locking structure;
[0013] The hoisting locking structure includes a base set on the upper end face of the main rod of the hanger, a central seat set on the upper end face of the base, and sliding grooves on both sides of the central seat, with clamping pieces slidably arranged in both sliding grooves.
[0014] Furthermore, the U-shaped fork has a U-shaped structure and is integrally formed; the U-shaped fork is integrally bent using a tubular component with a diameter of 6 mm.
[0015] Furthermore, the top of the sleeve hole is closed and an opening is formed below it, and the inner diameter of the sleeve hole is 7 mm.
[0016] Furthermore, the clamping piece is U-shaped and its bottom slides within the groove.
[0017] Furthermore, the hoisting locking structure also includes two internal threaded sleeves fixedly installed at the bottom of the center seat. Each of the two internal threaded sleeves is threaded with a bolt. The bottom of the center seat has two holes. Both bolts pass through the internal threaded sleeves and the center seat and extend to abut against the bottom of the clamping plate.
[0018] Furthermore, each of the hanging rods is fixedly provided with several bolts, which are arranged in an array along the transverse direction of the hanging rod; each bolt is fitted with a bolt washer and an electrophoresis component body, the electrophoresis component body is arranged in a circular shape at its center and fitted outside the bolt, and a nut is threaded onto the bolt.
[0019] In summary, this utility model has the following beneficial effects:
[0020] 1. By setting a U-shaped fork with an inner diameter of 6MM on the side of the main rod of the hanger, and cooperating with a sleeve with an inner diameter of 7MM on the side of the auxiliary rod of the hanger, in actual use, the sleeve is inserted into the U-shaped fork by gravity and suspended, forming a mechanical self-locking state. The connection between the two is stable and reliable, which can ensure the stability of the electrophoretic component body during electrophoresis.
[0021] 2. When the sleeve is fitted over the U-shaped fork, a small gap is formed between the closed sleeve and the U-shaped fork. The enclosed air in this gap is difficult to escape, so the coating liquid in this area cannot enter during the electrophoresis process, thus forming an "air bag", which is a natural coating shielding area. This prevents the electrophoretic paint from adhering to the contact surface, and ultimately, this area will not be painted during processing. Compared with traditional adhesive, oil brushing or manual masking processes, this reduces labor costs, avoids pollution, improves production efficiency and consistency, and avoids the phenomenon of paint accumulation and liquid contamination at both ends of the traditional two-end slotted disassembly fixture during electrophoretic coating.
[0022] 3. The fixture of this application does not require additional fasteners or clips during overall use, which simplifies the assembly process and is suitable for batch production on assembly lines. At the same time, the plug-in structure facilitates disassembly, maintenance or replacement of parts in the later stage, and the overall structure is stable and reliable. Attached Figure Description

[0030] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.
[0031] First embodiment;
[0032] Reference Figure 1-5 As shown, this is a hanging fixture for producing electrophoretic components in a preferred embodiment of the present invention, including a vertically arranged main hanging rod 1;
[0033] Several connecting blocks 2 are welded to the side of the main rod 1 from bottom to top;
[0034] Each connecting block 2 has a U-shaped fork 3 welded to its side;
[0035] It also includes several horizontally arranged hanger auxiliary rods 4, and each hanger auxiliary rod 4 has two sleeves 5 welded to its side;
[0036] A gap is formed between the two sleeves 5, and a sleeve hole 51 is opened at the bottom of the sleeve 5. The two sleeves 5 are sleeved on the outside of one of the U-shaped forks 3 through the sleeve hole 51.
[0037] A hoisting locking structure 6 is fixedly installed at the top of the main pole 1 of the hanger, and a crossbeam 10 is installed above the hoisting locking structure 6;
[0038] The hoisting locking structure 6 includes a base 61 set on the upper end face of the main rod 1 of the hanger. A center seat 62 is set on the upper end face of the base 61. Slide grooves 63 are opened on both sides of the center seat 62. Clamping pieces 64 are slidably arranged in both slide grooves 63.
[0039] In this embodiment, a U-shaped fork 3 with an inner diameter of 6 mm is provided on the side of the main rod 1 of the hanger, and a sleeve 5 with an inner diameter of 7 mm is provided on the side of the auxiliary rod 4 of the hanger. In actual use, the sleeve 5 is inserted into the U-shaped fork 3 by gravity and suspended, forming a mechanical self-locking state. The connection between the two is stable and reliable, which can ensure the stability of the electrophoresis component body 9 during electrophoresis.
[0040] Second embodiment;
[0041] Reference Figure 1-2 As shown, the U-shaped fork 3 has a "U" shaped structure and is integrally set; the U-shaped fork 3 uses a tubular component with a diameter of 6MM that is integrally bent.
[0042] In this embodiment, the U-shaped forks 3 can be installed on the side of the connecting block 2 by welding, and the connecting block 2 is also installed on the side of the main rod 1 of the hanger by welding. In use, the U-shaped forks 3 are arranged in an array at intervals along the vertical range of the main rod 1 of the hanger.
[0043] Third embodiment;
[0044] Reference Figure 3 As shown, the top of the sleeve hole 51 is closed and an opening is formed below it. The inner diameter of the sleeve hole 51 is 7 mm.
[0045] In this embodiment, the sleeve 5 can be fitted onto the outside of the U-shaped fork 3 through the sleeve hole 51; the distance between two adjacent sleeves 5 is adapted to the installation distance between the U-shaped forks 3.
[0046] Furthermore, when the sleeve 5 is fitted onto the outside of the U-shaped fork 3, a small gap is formed between the closed sleeve 5 and the U-shaped fork 3. The enclosed air in this gap is difficult to be expelled, so the coating liquid in this area cannot enter during the electrophoresis process, thus forming an "air bag", that is, a natural coating shielding area, which prevents the electrophoretic paint from adhering to the contact surface. Ultimately, this area will not be painted during processing. Compared with traditional adhesive, oil brushing or manual masking processes, it reduces labor costs, avoids pollution, improves production efficiency and consistency, and avoids the phenomenon of paint accumulation and liquid contamination at both ends of the traditional two-end slotted disassembly fixture during electrophoretic coating.
[0047] Fourth embodiment;
[0048] Reference Figure 4 As shown, the clamping piece 64 is U-shaped and its bottom slides in the groove 63; the hoisting locking structure 6 also includes two internal threaded sleeves 65 fixedly installed at the bottom of the center seat 62. Each of the two internal threaded sleeves 65 is threaded with a bolt 66. The bottom of the center seat 62 has two holes. Both bolts 66 pass through the internal threaded sleeves 65 and the center seat 62 and extend to abut against the bottom of the clamping piece 64.
[0049] In this embodiment, the user loosens the two bolts 66, which then disengages from the clamping piece 64, allowing the clamping piece 64 to slide freely within the groove 63. The user can adjust the spacing between the two clamping pieces 64 according to the width of the crossbeam 10, so that the two clamping pieces 64 can clamp the crossbeam 10. Subsequently, the user tightens the two bolts 66 again, so that the two bolts 66 pass through the center seat 62 until they are in close contact with the clamping piece 64. At this time, the clamping piece 64 is easily locked, while simultaneously clamping the crossbeam 10.
[0050] Furthermore, the crossbeam 10 can be set horizontally on the trolley or in the electrophoresis processing workshop, and the main rod 1 of the hanger can be locked on the crossbeam 10 by the hoisting and locking structure 6, so that the main rod 1 of the hanger is in a suspended position.
[0051] Fifth embodiment;
[0052] Reference Figure 1As shown, each hanger sub-rod 4 is fixedly provided with several bolts 7, and the several bolts 7 are arranged in an array along the transverse direction of the hanger sub-rod 4; each bolt 7 is fitted with a bolt washer 8 and an electrophoresis component body 9, the electrophoresis component body 9 is arranged in a circular shape at the center and is fitted outside the bolt 7, and a nut 71 is threadedly connected to the bolt 7.
[0053] In this embodiment, when the user needs to position the electrophoretic component body 9 and perform electrophoretic processing in a stable state on the hanger auxiliary rod 4, the bolt washer 8 is placed on the stud of the bolt 7, and then the electrophoretic component body 9 is placed on the bolt washer 8. After the electrophoretic component body 9 is placed, the nut 71 is used to lock the electrophoretic component body 9 on the bolt 7.
[0054] Furthermore, in one embodiment, the electrophoresis component body 9 is annular in the middle, with X-shaped support arms protruding from both sides of the annulus. The electrophoresis component body 9 can be fitted onto the outside of the bolt 7 using the annulus. The bolt 7 on the hanger auxiliary rod 4 can be welded to match different sizes and models of electrophoresis component bodies 9. During subsequent maintenance or replacement, only a single hanger auxiliary rod 4 needs to be disassembled, and hanger auxiliary rods 4 with different sizes of bolts 7 welded on them can be selected according to the size of the electrophoresis component body 9, thus achieving rapid adaptation to the electrophoresis component body 9.
[0055] Specific implementation process:
[0056] Step 1: Using the lifting and locking structure 6, the main rod 1 of the hanger is locked to the crossbeam 10, thus suspending the main rod 1. Multiple U-shaped forks 3 with a diameter of 6 mm are arranged on the main rod 1 to support the secondary rod 4. A sleeve 5 with an inner diameter of 7 mm is provided on one side of the secondary rod 4, which can be inserted into and fitted into the U-shaped forks 3 of the main rod 1. This structure utilizes the self-weight of the secondary rod 4 for stable positioning. With the insertion and connection between the sleeve 5 and the U-shaped forks 3, no additional fasteners are required, making installation simple.
[0057] Step 2: After the sleeve 5 is inserted into the U-shaped fork 3, its closed structure creates a relatively sealed air gap between the sleeve 5 and the U-shaped fork 3, preventing the penetration of the electrophoretic paint liquid and thus preventing the formation of an electrophoretic coating in this area. This creates an exposed and stable conductive contact area, ensuring that the current flows smoothly through the fixture to the workpiece being coated throughout the entire electrophoretic process, achieving excellent conductivity and coating consistency.
[0058] Step 3: Based on the structural requirements of different sized electrophoresis component bodies 9, the hanger auxiliary rods 4 can be inserted into different U-shaped slots as needed, flexibly configuring the number and position of the hangers. During subsequent maintenance or replacement, only a single hanger auxiliary rod 4 needs to be disassembled for quick replacement, avoiding affecting the stability of the entire hanger system.
