Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for electrophoresis processing, specifically to a hanger for electrophoresis processing with a spacing adjustment structure. Background Technology

[0002] Electrophoretic coating is a process in which metal parts are placed on a fixture, which then immerses the parts in an electrolyte solution. The metal parts are coated and protected by electroplating, and the coated parts are then removed. The fixture is an essential part of the electrophoretic coating process.

[0003] However, existing electrophoresis processing fixtures still have certain problems:

[0004] For example, a hanger for electrophoretic powder spraying of small workpieces, application number CN202322613271.1, relates to the field of electrophoretic hanger technology; the hanger for electrophoretic powder spraying of small workpieces includes a fixed rod, the upper end of which is connected to a hook, and multiple sets of plug-in components are provided at both the front and rear ends of the fixed rod. The upper ends of the multiple sets of plug-in components are connected to a crossbar, the front end of which is connected to multiple sets of hanging rods, the lower end of the fixed rod is provided with a connecting block, the lower end of which is plugged into a fixed block, and the two sides of the fixed block are connected to support devices;

[0005] Existing electrophoretic processing fixtures are usually fixed structures with fixed spacing between suspension positions, which can only accommodate workpieces of specific sizes. When different sizes of workpieces need to be processed, different fixtures often need to be changed, which not only increases production costs but also makes the operation cumbersome and affects processing efficiency.

[0006] Therefore, we propose a fixture for electrophoresis processing with a spacing adjustment structure to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this utility model is to provide a hanger for electrophoretic processing with an adjustable spacing structure, so as to solve the problem that the electrophoretic processing hangers mentioned in the background art are usually fixed structures with fixed spacing of the suspension positions, which can only adapt to workpieces of specific sizes. When it is necessary to process workpieces of different sizes, different hangers often need to be changed, which not only increases production costs, but also makes the operation cumbersome and affects processing efficiency.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a hanger for electrophoresis processing with an adjustable spacing structure, comprising a hanger body and a hook. The top of the hanger body is welded with a hook. Two sets of first sliding grooves are symmetrically opened on the inner side of the hanger body. Four layers of suspension rods are provided in the middle of the hanger body. First sliders are fixed at both ends of the four layers of suspension rods, and the first sliders are slidably connected to the first sliding grooves. Sliding sleeves are welded to both ends of the suspension rods. First locking bolts are threaded through and threaded onto the outer surface of the sliding sleeves, and the ends of the first locking bolts are tightly fitted and connected to the outer surface of the hanger body. A mounting base is slidably connected to the outer surface of the suspension rods. A hook is welded to the outer side of the mounting base. A second locking bolt is threaded through and threaded onto the rear end face of the mounting base, and the ends of the second locking bolts are tightly fitted and connected to the rear end face of the suspension rods.

[0009] Using the above technical solution, the suspension rod moves up and down as a whole by sliding the first slider in the first groove, and the position is fixed by the first locking bolt; the mounting seat slides on the suspension rod and is fixed by the second locking bolt, thereby adjusting the hook spacing. The hook spacing can be flexibly adjusted according to workpieces of different sizes, avoiding workpiece collision and obstruction, improving the quality and efficiency of electrophoretic processing, and adapting to diverse workpiece suspension needs.

[0010] Preferably, the hanger body has a rectangular frame structure, and the bottom of the hanger body is a triangular support structure.

[0011] The above technical solution provides a stable basic framework for the fixture, ensuring the regularity and strength of the overall structure. The bottom adopts a triangular support structure, which utilizes the stable geometric properties of triangles. The three sides of the triangle support each other to form a stable structure, which enhances the overall stability of the fixture and prevents it from shaking or tipping over due to the weight of the workpiece or external forces during the electrophoretic processing.

[0012] Preferably, the sliding sleeve has a hollow rectangular structure, and the sliding sleeve is fitted onto the outer surface of the hanger body and is in close sliding connection with the outer surface of the hanger body.

[0013] By adopting the above technical solution, the hollow rectangular sliding sleeve is slidably connected to the outer surface of the fixture body, allowing the suspension rod to move flexibly on the fixture body through the sliding sleeve, which facilitates the adjustment of the suspension position according to the workpiece size; and the close sliding ensures the smoothness of movement, avoids shaking, and improves the stability of workpiece suspension during electrophoresis.

[0014] Preferably, the upper end face of the suspension rod is provided with a second sliding groove along the length direction of the suspension rod, and the upper end face of the suspension rod is provided with a plurality of positioning holes at equal intervals, and the plurality of positioning holes are designed to communicate with the second sliding groove, and the diameter of the positioning holes is greater than the width of the second sliding groove.

[0015] The above technical solution utilizes a second slide groove to provide a sliding track for the mounting base, allowing it to move along the length of the suspension rod. The positioning hole is connected to the second slide groove and has a larger diameter. When the mounting base moves to a suitable position, the positioning component is inserted into the positioning hole to position the mounting base. The second slide groove facilitates flexible adjustment of the position of the mounting base and hook to accommodate workpieces of different sizes. The positioning hole can accurately fix the mounting base, preventing it from sliding during electrophoresis processing, ensuring stable workpiece suspension, and improving processing quality.

[0016] Preferably, the outer surface of the mounting base is provided with a third sliding groove, a return spring is fixed to the top of the inner side of the third sliding groove, a connecting plate is fixed to the bottom end of the return spring, a positioning bolt is fixed to the bottom of the connecting plate, and the positioning bolt passes through the bottom end of the mounting base and engages with the positioning hole.

[0017] By adopting the above technical solution, relying on the elastic characteristics of the return spring, when an external force is applied to the connecting plate, the return spring is compressed, causing the positioning bolt to move upward and disengage from the positioning hole, allowing the mounting base to slide freely; after the external force is removed, the return spring returns to its deformation, pushing the connecting plate and the positioning bolt downward, allowing the positioning bolt to re-engage into the positioning hole. This allows for convenient and quick movement of the mounting base to adjust the hook position, adapting to workpieces of different sizes; at the same time, the engagement of the positioning bolt and the positioning hole can precisely fix the mounting base, preventing it from shaking during electrophoretic processing and ensuring processing stability.

[0018] Preferably, a second slider is fixed to the bottom of the mounting base, and the second slider is in a sliding connection with the second groove.

[0019] By adopting the above technical solution, the shape of the second slider matches the second slide groove, so that the second slider can be embedded in the second slide groove. When relative sliding occurs between the two contact surfaces, the mounting seat moves along the length of the suspension rod, providing a stable guide for the movement of the mounting seat, ensuring the linearity and smoothness of the movement of the mounting seat, facilitating precise adjustment of the hook position to adapt to different workpieces, and improving the flexibility and reliability of electrophoretic processing.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. The fixture body adopts a rectangular frame with a triangular structure support, which has good stability and can effectively resist the external force and workpiece weight during electrophoresis processing, preventing shaking and tipping. The first sliding groove on the inner side is symmetrical and slides in close contact with the first sliders at both ends of the suspension rod. With the assistance of the sliding sleeve, the suspension rod can move up and down smoothly. It is then fixed by the first locking bolt. The vertical spacing of the four suspension rods can be adjusted flexibly and accurately to adapt to workpieces of different sizes, avoid collision and obstruction, and improve processing quality and efficiency.

[0022] 2. The mounting base slides along the second slide groove on the suspension rod via the second slider at the bottom, allowing it to move flexibly along the rod and easily adjust the hook position according to the workpiece size. The positioning holes, which are evenly distributed and communicate with the second slide groove, along with the return spring, connecting plate, and positioning bolt, can quickly and accurately position the mounting base. The second locking bolt on the rear end face of the mounting base is then tightly fitted and fixed to the suspension rod, preventing the mounting base from shaking during electrophoresis, ensuring stable workpiece suspension, and improving processing quality and efficiency.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Please see Figures 1-4 This utility model provides a technical solution: an electrophoresis processing hanger with an adjustable spacing structure, comprising a hanger body 1 and a hook 2. The hook 2 is welded to the top of the hanger body 1. Two sets of first sliding grooves 3 are symmetrically opened on the inner side of the hanger body 1. Four layers of suspension rods 4 are arranged in the middle of the hanger body 1. First sliders 5 are fixed at both ends of the four layers of suspension rods 4, and the first sliders 5 are slidably connected to the first sliding grooves 3. Sliding sleeves 6 are welded to both ends of the suspension rods 4. The outer surface of the sliding sleeves 6 is threaded with first locking bolts 7, and the end of the first locking bolts 7 is tightly connected to the outer surface of the hanger body 1. The hanger body 1 has a rectangular frame structure, and the bottom of the hanger body 1 is a triangular support structure. The sliding sleeves 6 have a hollow rectangular structure, and the sliding sleeves 6 are fitted onto the outer surface of the hanger body 1 and are slidably connected to the outer surface of the hanger body 1.

[0030] The fixture body 1 adopts a rectangular frame structure, providing a regular and stable support frame for the whole. Its bottom end is designed as a triangular structure bracket, which utilizes the principle of triangle stability to enhance the overall stability of the fixture and prevent it from shaking or tipping over due to external forces or workpiece weight during electrophoresis. Two sets of first sliding grooves 3 are symmetrically opened on the inner side of the fixture body 1, which are in close contact with the first sliders 5 fixed at both ends of the suspension rod 4, allowing the suspension rod 4 to move up and down along the first sliding grooves 3 on the fixture body 1. This allows the vertical position of the suspension rod 4 to be flexibly adjusted according to workpieces of different sizes. Hollow rectangular sliding sleeves 6 welded to both ends of the suspension rod 4 are fitted onto the outer surface of the fixture body 1. The sliding surface of the sleeve 6 is closely fitted to ensure the smooth movement of the suspension rod 4. The first locking bolt 7, which is threaded through the outer surface of the sleeve 6, is tightly fitted to the outer surface of the fixture body 1. When the suspension rod 4 moves to the appropriate position, the first locking bolt 7 is tightened to increase the friction and fix the sleeve 6 and the suspension rod 4 to the fixture body 1. This ensures the stability of the suspension rod 4 during electrophoresis, thereby ensuring the reliability of the workpiece suspension, improving the quality of electrophoresis, and facilitating the adjustment of the height of the suspension rod 4 on the fixture body 1 according to the usage requirements. This adapts to the processing requirements of workpieces of different sizes, avoids workpiece collision and obstruction, and improves the quality and efficiency of electrophoresis.

[0031] A mounting base 10 is slidably connected to the outer surface of the suspension rod 4. A hook 11 is welded to the outer side of the mounting base 10. A second locking bolt 17 is threaded through and threaded onto the rear end face of the mounting base 10, and the end of the second locking bolt 17 is tightly fitted to the rear end face of the suspension rod 4. A second sliding groove 8 is formed on the upper end face of the suspension rod 4 along its length. Several positioning holes 9 are equally spaced on the upper end face of the suspension rod 4, and these positioning holes 9 are designed to communicate with the second sliding groove 8. The diameter of the positioning holes 9 is larger than the width of the second sliding groove 8. A third sliding groove 12 is formed on the outer surface of the mounting base 10. A return spring 13 is fixed to the top of the inner side of the third sliding groove 12. A connecting plate 14 is fixed to the bottom end of the return spring 13. A positioning bolt 15 is fixed to the bottom of the connecting plate 14, and the positioning bolt 15 passes through the bottom end of the mounting base 10 and engages with the positioning hole 9. A second slider 16 is fixed to the bottom of the mounting base 10, and the second slider 16 is slidably connected to the second sliding groove 8.

[0032] On the suspension rod 4, the mounting base 10 is slidably connected to the second sliding groove 8 on the upper end surface of the suspension rod 4 via a second slider 16 fixed at the bottom. This allows the mounting base 10 to move flexibly along the length of the suspension rod 4, so as to adjust the position of the hook 11 according to different workpiece sizes, meet the suspension requirements of workpieces of different sizes, avoid collisions between workpieces during electrophoresis, reduce workpiece damage, and improve workpiece processing efficiency. A return spring 13 is installed in the third sliding groove 12 on the outer surface of the mounting base 10. Its bottom end is connected to the connecting plate 14 and the positioning bolt 15. When the connecting plate 14 is pressed upward, a return spring 13 is installed. At time 4, the return spring 13 is compressed, and the positioning bolt 15 moves upward and disengages from the positioning hole 9. At this time, the mounting seat 10 can move freely. After being released, the return spring 13 returns to its original deformation and pushes the positioning bolt 15 into the positioning hole 9, which is equidistant and communicates with the second slide groove 8 and has a larger diameter, thus achieving precise positioning of the mounting seat 10. The second locking bolt 17, which is threaded through the rear end face of the mounting seat 10, has its end tightly fitted with the rear end face of the suspension rod 4. After tightening, it can further fix the mounting seat 10, prevent it from shaking during the electrophoretic processing, ensure the stability of the workpiece suspension, and improve the processing quality.

[0033] Working principle: For this type of electrophoretic processing fixture with a spacing adjustment structure, the fixture body 1 provides stable support for the whole. The first sliding groove 3 on its inner side slides against the first sliders 5 at both ends of the suspension rod 4, allowing the suspension rod 4 to move up and down. The sliding sleeves 6 at both ends slide against the fixture body 1 to ensure stability. After moving into place, the first locking bolt 7 is tightened to fix the suspension rod 4. On the suspension rod 4, the mounting seat 10 moves along the rod by sliding against the second sliding groove 8 through the second slider 16 at the bottom. Pressing the connecting plate 14 upward compresses the return spring 13, and the positioning bolt 15 disengages from the positioning hole 9, allowing the mounting seat 10 to move freely. After releasing, the return spring 13 pushes the positioning bolt 15 into the positioning hole 9 for precise positioning. Finally, the second locking bolt 17 on the rear end face of the mounting seat 10 is tightened for further fixation to prevent shaking during electrophoretic processing.
