Description

Technical Field

[0001] This utility model relates to the field of electrophoresis hanger technology, specifically a convenient electrophoresis hanger. Background Technology

[0002] As described in the published patent "Electrophoretic Hanger" with publication number CN207418888U, electrophoretic paint has superior mechanical properties and corrosion resistance, excellent paint film surface quality, and good resistance to over-baking and yellowing. Therefore, it is widely used in the coating of workpieces with high corrosion resistance requirements, such as automobile bodies, frames, wheels and their parts.

[0003] During the electrophoresis process, since the workpieces to be coated have different sizes and heights, in order to accommodate all workpiece sizes and heights, the distance between the hooks should be designed to be as large as possible. This will reduce the number of workpieces that can be electrophoretically coated at one time, thus affecting production efficiency.

[0004] As described in the published patent CN220317997U, "An Electrophoretic Hanger for Zinc Removal," electrophoresis is short for electrophoretic phenomenon, referring to the phenomenon where charged particles move towards an electrode with the opposite charge under the influence of an electric field. When performing electrophoretic treatment on workpieces, the workpiece needs to be placed on a hanger. To address the electrophoretic problem in galvanized products, a zinc removal and rust prevention process is employed, which requires the use of an electrophoretic hanger for zinc removal.

[0005] Although the existing technology has enabled the suspension of workpieces in electrophoresis processing, the spacing between the hanging rods 102 cannot be adjusted during use, making it unsuitable for suspending workpieces of different sizes. The electrophoresis hanger has a limited range of applications, and the hooks of the electrophoresis hanger lack a limiting mechanism, making it easy for the workpiece to fall off the hook, resulting in poor workpiece suspension stability.

[0006] In summary, some existing electrophoresis hangers have the problem of inconvenient adjustment of the hanging rods, making them unsuitable for suspending workpieces of different sizes. Utility Model Content

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-9 A convenient electrophoresis hanger includes a bracket 100 with a suspension hook 101 fixed at the upper end, and a plurality of hanging rods 102 are evenly hung on the bracket 100 along the length direction.

[0035] The rear end of the hanging rod 102 is fixedly provided with a snap-fit ​​assembly 103 that engages with the bracket 100, and the front end of the hanging rod 102 is fixedly provided with a clamping assembly 104 for clamping the workpiece.

[0036] The snap-fit ​​assembly 103 includes an L-shaped hook 105 fixedly connected to the rear end of the hanging rod 102. The lower end of the hook is provided with a first snap-fit ​​rod 106 that retracts inward. The first snap-fit ​​rod 106 abuts against the lower bottom surface of the bracket 100. The inner side of the L-shaped hook 105 is provided with a second snap-fit ​​rod 107 that abuts against the upper top surface of the bracket 100.

[0037] The clamping assembly 104 includes a clamp 110 connecting rod 108 fixedly connected to the front end of the hanging rod 102. A U-shaped connector 109 is fixedly connected to the front end of the clamp 110 connecting rod 108, and a clamp 110 for clamping workpieces is fixedly connected to the end of the U-shaped connector 109.

[0038] With the innovative snap-fit ​​assembly 103 (L-shaped hook 105, inwardly retracting first snap-fit ​​rod 106 and inner second snap-fit ​​rod 107), the hanging rod 102 can be quickly and easily disassembled and re-snapped along the length of the bracket 100. Users can freely adjust the distance between adjacent hanging rods 102 according to the specific dimensions (especially height and width) of the workpiece to be processed without tools. This completely solves the problem that traditional fixed-spacing hangers cannot adapt to workpieces of different sizes, greatly expands the versatility of the hangers, and one set of hangers can meet the suspension needs of workpieces of various specifications without the need for frequent replacement of special hangers.

[0039] The design of the snap-fit ​​assembly 103 provides dual limiting and fixing. The inwardly rolled structure of the first snap-fit ​​rod 106 allows it to firmly hook and abut against the bottom surface of the bracket 100, forming the main load-bearing and anti-slip constraint. At the same time, the second snap-fit ​​rod 107 abuts against the top surface of the bracket 100, effectively preventing the hanging rod 102 from accidentally flipping sideways or coming off upward during use (such as entering or exiting the electrophoresis tank or shaking). This dual snap-fit ​​mechanism ensures that the hanging rod 102 remains extremely stable in the dynamic environment of the electrophoresis process after being adjusted to the required position, avoiding workpiece collision or spacing changes due to the displacement of the hanging rod 102.

[0040] The design of the clamping assembly 104 (clamp 110 connecting rod 108, U-shaped connector 109, special clamp 110) combined with the clamping force of the clamp 110 itself on the workpiece provides reliable constraint for the workpiece. Compared with a simple hook, this design can more effectively prevent the workpiece from rotating, swinging or falling off completely when it is subjected to liquid flow, electric field force or slight collision in the electrophoresis tank. It significantly improves the stability and safety of workpiece suspension and reduces the risk of defective products and production stoppages caused by workpiece falling.

[0041] The freely adjustable spacing of the hanging rods 102 means that workpieces of different sizes can be arranged more efficiently on the same hanger. For small workpieces, the spacing of the hanging rods 102 can be reduced to increase the number of workpieces processed at one time; for large workpieces, the spacing can be increased to ensure sufficient processing space and avoid interference. This ability to optimize on demand significantly improves the loading efficiency and equipment utilization of the electrophoresis production line, while reducing downtime caused by changing hangers, thus improving overall production efficiency and flexibility in responding to different production tasks.

[0042] This utility model of a convenient electrophoresis hanger achieves adjustable snap-fit ​​of the hanging rod 102 on the bracket 100 through an innovative snap-fit ​​component 103, which solves the problem of fixed spacing of the hanging rod 102 in the prior art and inability to adapt to workpieces of different sizes. At the same time, the clamping component 104 provides stable workpiece clamping and effectively prevents it from falling off, thereby improving the applicability and working efficiency of the electrophoresis hanger and enhancing the stability of workpiece suspension.

[0043] In this embodiment of the utility model, the clamp 110 includes a first gripping bending portion 111 fixedly connected to the U-shaped connector 109. A first clamping bending portion 112 is fixedly connected to the front end of the first gripping bending portion 111. A spring member 113 is fixedly connected to the rear end of the first clamping bending portion 112. A second clamping bending portion 114 symmetrical to the first clamping bending portion 112 is fixedly connected to the upper end of the spring member 113. A second gripping bending portion 115 symmetrical to the first gripping bending portion 111 is fixedly connected to the rear end of the second clamping bending portion 114.

[0044] The first gripping bend 111 and the second gripping bend 115, which are symmetrically arranged, form a stable gripping base. Combined with the spring 113, an adaptive elastic preload is provided, so that the first clamping bend 112 and the second clamping bend 114 can automatically adjust the opening and closing angle according to the thickness of the workpiece. While achieving a firm engagement, rigid clamping damage to the workpiece surface is avoided, which significantly improves the clamping stability and workpiece adaptability, and effectively prevents the workpiece from falling off due to the impact or vibration of the bath solution during the electrophoresis process.

[0045] In this embodiment of the utility model, the first locking rod 106 is inclined to the rear and lower, the second locking rod 107 is inclined to the front and upper, the second locking rod 107 and the first locking rod 106 are coplanar with the hanging rod 102, and the second locking rod 107 and the first locking rod 106 are parallel to each other.

[0046] The symmetrical design of the first locking rod 106 tilting downwards and backwards, and the second locking rod 107 tilting upwards and forwards, combined with their parallel and coplanar layout with the hanging rod 102, forms a two-way self-locking mechanical structure. The tilt angle of the first locking rod 106 strengthens the engagement with the bottom surface of the bracket 100, preventing the hanging rod 102 from floating and dislodging, while the tilt angle of the second locking rod 107 effectively strengthens the engagement with the top surface of the bracket 100, preventing the hanging rod 102 from rotating and dislodging. The parallel and coplanar design further ensures a uniform distribution of locking force, significantly improving the vibration resistance and overall stability of the hanging rod 102 in the dynamic electrophoresis environment, and eliminating the risk of accidental disengagement due to impact.

[0047] In this embodiment of the utility model, the bracket 100 is provided with a plurality of first snap-fit ​​grooves 116 and second snap-fit ​​grooves 117 that are respectively snap-fitted and engaged with the first snap-fit ​​rod 106 and the second snap-fit ​​rod 107 along the length direction.

[0048] By evenly opening first locking grooves 116 and second locking grooves 117 on the bracket 100 to precisely match the first locking rod 106 and the second locking rod 107, the fast and accurate positioning and double anti-disengagement locking of the hanging rod 102 are achieved. The uniform distribution of the locking grooves provides a standardized spacing adjustment benchmark, allowing the hanging rod 102 to flexibly select the locking point according to the workpiece size, ensuring the efficiency and consistency of the spacing adjustment. At the same time, the geometric fit between the locking groove and the locking rod significantly increases the contact area, and the interlocking effect of the mechanical interlock strengthens the biting strength between the hook and the bracket 100. This eliminates the error of manual visual positioning and effectively resists the impact of fluid and mechanical vibration in the electrophoresis tank, fundamentally eliminating the risk of displacement or disengagement of the hanging rod 102, and greatly improving the load-bearing stability and applicability of the hanger.

[0049] In this embodiment of the present invention, the first snap-fit ​​groove 116 is provided with a plurality of grooves evenly along the length of the lower bottom surface of the bracket 100 and engages with the first snap-fit ​​rod 106. The second snap-fit ​​groove 117 is provided with a plurality of grooves evenly along the length of the upper top surface of the bracket 100 and engages with the second snap-fit ​​rod 107. The first snap-fit ​​groove 116 and the second snap-fit ​​groove 117 are respectively inclined. The inclination angle of the first snap-fit ​​groove 116 is the same as that of the first snap-fit ​​rod 106, and the inclination angle of the second snap-fit ​​groove 117 is the same as that of the second snap-fit ​​rod 107.

[0050] A first locking groove 116 and a second locking groove 117 with precisely matched inclination angles are evenly opened on the bottom and top surfaces of the bracket 100, respectively. First, the inclination angles of the locking grooves and the corresponding locking rods are completely consistent, forming a geometrically conformal locking structure, maximizing the contact area and ensuring uniform stress distribution, significantly improving tensile strength and shear strength. Second, the parallel layout of the double grooves and the coplanar design with the hanging rod 102 ensure that the force transmission path of the locking is without deviation, completely eliminating the risk of local stress concentration or locking loosening caused by angular deviation. Third, the evenly distributed standardized grooves provide a high-precision positioning reference for the hanging rod 102, which simplifies the spacing adjustment operation and ensures the mechanical balance when multiple hanging rods 102 work together to bear the load. Thus, under harsh working conditions such as high-frequency vibration and fluid impact in the electrophoresis tank, the absolute stability of the fixture with zero displacement can still be maintained, greatly extending the service life of the equipment.

[0051] In this embodiment of the utility model, the front end of the hanging rod 102 is provided with a threaded connection hole 118, and the rear end of the clamp 110 connecting rod 108 is provided with a threaded connector 119 that is screwed into the threaded connection hole 118.

[0052] By creating a threaded connection hole 118 at the front end of the hanging rod 102 and threadedly engaging it with the threaded connector 119 at the rear end of the connecting rod 108 of the chuck 110, a high-rigidity, zero-clearance modular connection system is constructed. This design not only completely eliminates the risk of loosening of the clamping component 104 under vibration through the self-locking effect of the thread, ensuring stable torque transmission when the workpiece is under force, but also significantly improves maintenance flexibility due to its detachable nature. When the chuck 110 is worn or needs to be replaced, it can be quickly replaced simply by unscrewing the threaded connector 119, without scrapping the entire hanging rod 102, greatly reducing maintenance costs and downtime. At the same time, the precise engagement of the threads achieves micron-level assembly accuracy, fundamentally eliminating deformation deviations caused by traditional welding or riveting, ensuring that all clamping components 104 are always in the optimal working position, and comprehensively optimizing the reliability and service life of the electrophoresis fixture.

[0053] In this embodiment of the present invention, the end of the first snap-fit ​​rod 106 is provided with a backward-bent head 120;

[0054] A backward-bending bend head 120 is added to the end of the first clip rod 106. The smooth transition design at the end of the bend head 120 completely eliminates the sharp angle stress concentration point, making the hanger more resistant and avoiding scratching the surface coating of the bracket 100.

[0055] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
