Description

Technical Field

[0001] This utility model relates to the field of electrophoretic part processing, and in particular to a multi-pore shielding rapid repair tool. Background Technology

[0002] Electrophoresis is a separation technique that uses an electric field to move charged particles (such as ions or molecules) within that field. This process relies on the ability of charged substances to migrate in an electric field, typically by using an electric current to facilitate migration in a medium (such as water, gel, or other electrolyte solutions), thereby achieving the separation of different substances. In the coating industry, electrophoresis refers to an electrophoretic coating technique (or electrophoretic painting), which uses an electric field to deposit charged particles from the coating onto a metal surface, forming a uniform coating. This coating method is commonly used in industries such as automotive and home appliances to improve the adhesion, uniformity, and corrosion resistance of coatings.

[0003] In the electrophoretic coating process, the workpiece passes through an electrophoretic pool, where an electric field is applied to cause the coating to be deposited uniformly on the workpiece surface. For workpieces with holes or complex structures, the holes usually need to be shielded. In industrial automation equipment and control systems, shielding holes are used to prevent external electromagnetic interference from affecting sensors and control modules, thereby protecting internal circuits from electrostatic and electromagnetic interference, ensuring the normal operation of the equipment and the stability of data transmission.

[0004] Electrophoretic coating requires strict shielding of the holes. High-temperature adhesive tape or silicone plugs are typically used to seal the holes, preventing electrophoretic coating from entering. However, the defect rate of shielded holes after electrophoresis is high, necessitating rework to remove excess paint. This process typically involves scraping away excess paint with a utility knife, a tedious and skill-intensive procedure. Furthermore, this method cannot guarantee the tolerance range of the shielding position. Ensuring the paint surface is within the shielding hole tolerance range minimizes exposed substrate and prevents corrosion, making it crucial for the quality of the electrophoretic coating. More importantly, the use of utility knives in the field poses safety hazards, potentially causing cuts and increasing production risks and management difficulties. Therefore, this paper proposes a multi-aperture shielding rapid rework tool to address these issues. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-aperture shielded quick repair tool, which realizes the quick installation of tungsten carbide blades through a quick-release structure, and uses the stepped cutting edge of the tungsten carbide blades to remove the paint from the machining holes of electrophoretic parts.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A multi-aperture shielding quick repair tool includes a quick-release assembly, on which a positioning rod is mounted. The bottom end of the positioning rod has a rectangular groove, and a tungsten carbide blade body is clamped in the rectangular groove. Two sets of bolts are externally threaded onto the positioning rod, and holes are opened on the tungsten carbide blade body corresponding to the positions of the bolts. The bolts pass through the tungsten carbide blade body and extend to the other side of the positioning rod.

[0008] The tungsten carbide blade body has a trapezoidal sheet structure and several stepped cutting edges are provided on both sides. The stepped cutting edges are distributed in a stepped manner and the dimensions on both sides are symmetrically arranged.

[0009] The quick-release assembly includes an outer sleeve, which is cylindrical and has a cavity inside. A positioning ring is embedded at the bottom of the outer sleeve, and several clamping pieces are arranged around the top of the positioning ring along its center.

[0010] The positioning ring has a through-hole;

[0011] The clamping plates are separated sheet-like cones and are formed by equally dividing a complete cone;

[0012] An adjusting cylinder is rotatably disposed inside the outer sleeve. The inner wall of the adjusting cylinder has a hole and an inner conical surface is formed at the hole wall.

[0013] Furthermore, the other end of several of the clamping pieces is fixedly disposed with a positioning ring; several positioning grooves are formed around the center of the positioning ring.

[0014] Furthermore, the inner bottom wall of the outer sleeve is provided with a plurality of insert blocks protruding around its center, and the plurality of insert blocks are sequentially corresponding to the positioning grooves and the two are inserted into each other.

[0015] Furthermore, the inner wall of the top of the outer sleeve is provided with a second thread, and the outer side of the adjusting cylinder is provided with a first thread, the first thread and the second thread being threadedly engaged.

[0016] Furthermore, the angle of the inner conical surface opened on the inner wall of the adjusting cylinder is adapted to the conical surface of the clamping piece, and the inner conical surface can surround several clamping pieces.

[0017] Furthermore, a gripping rod is fixedly provided at the top of the adjusting cylinder, and a gripping groove is provided on the outside of the outer sleeve.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. The tungsten carbide blade body, arranged in a stepped shape, works in conjunction with the stepped cutting edge on the tungsten carbide blade body. When the tungsten carbide blade body passes through the shielding hole of the electrophoretic part, the stepped cutting edge can contact the surface of the shielding hole. When the user rotates the quick-release assembly, the tungsten carbide blade body installed in the quick-release assembly will rotate synchronously. When the tungsten carbide blade body rotates one revolution, the stepped cutting edge can scrape off the paint on the surface of the shielding hole during the rotation, ensuring the smoothness and consistency of the electrophoretic part surface. At the same time, the stepped cutting edge can automatically adapt to shielding holes of different diameters and perform rework, thereby greatly improving the speed of rework of shielding holes.

[0020] 2. In actual use, through the mutual movement and cooperation of multiple structures set in the quick-release assembly, the quick-release assembly can quickly clamp positioning rods of different lengths. By clamping and installing the positioning rods, users can quickly replace positioning rods of different lengths within the quick-release assembly. Thus, by changing the positioning rods, the processing position of the tungsten carbide blade body can be changed according to the requirements. For example, when reworking shielding holes in different positions, a positioning rod with a longer dimension can allow the tungsten carbide blade body to better approach the shielding hole and rotate it to remove paint.

[0021] 3. By installing the quick-release assembly and the positioning rod, the user can hold the gripping rod on the quick-release assembly, which allows for easy rotation control of the positioning rod. Through the installation between the positioning rod and the tungsten carbide blade body, the positioning rod can ultimately drive the tungsten carbide blade body to rotate, thus completing the repair of the shielding hole.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] 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.

[0028] First embodiment;

[0029] Reference Figure 1-3 As shown, a multi-aperture shielded quick repair tool according to a preferred embodiment of the present invention includes a quick-release assembly 1, a positioning rod 2 mounted on the quick-release assembly 1, a rectangular groove with a tungsten carbide blade body 4 clamped in the rectangular groove; two sets of bolts 3 are threadedly connected to the external of the positioning rod 2, and holes are opened on the tungsten carbide blade body 4 corresponding to the positions of the bolts 3; the bolts 3 pass through the tungsten carbide blade body 4 and extend to the other side of the positioning rod 2;

[0030] The tungsten carbide blade body 4 has a trapezoidal sheet structure and several stepped cutting edges 41 are provided on both sides. The stepped cutting edges 41 are distributed in a stepped manner and the dimensions on both sides are symmetrically arranged.

[0031] The quick-release assembly 1 includes an outer sleeve 11, which is cylindrical and has a cavity inside. A positioning ring 13 is embedded at the bottom of the outer sleeve 11, and a number of clamping pieces 15 are arranged around the top of the positioning ring 13 along its center.

[0032] A through hole 131 is provided on the positioning ring 13;

[0033] Several clamping plates 15 are separate plate-shaped cones and are formed by equally cutting a complete cone;

[0034] An adjusting cylinder 16 is rotatably installed inside the outer sleeve 11. The inner wall of the adjusting cylinder 16 has a hole and an inner conical surface 18 is provided at the hole wall.

[0035] In this embodiment, the tungsten carbide blade body 4 is arranged in a stepped shape, and the stepped cutting edge 41 is opened on the tungsten carbide blade body 4. When the tungsten carbide blade body 4 passes through the shielding hole of the electrophoretic part, the stepped cutting edge 41 can contact the surface of the shielding hole. When the user rotates the quick-release assembly 1, the tungsten carbide blade body 4 installed in the quick-release assembly 1 will rotate synchronously. When the tungsten carbide blade body 4 rotates one revolution, the stepped cutting edge 41 can scrape off the paint on the surface of the shielding hole during the rotation, ensuring the smoothness and consistency of the surface of the electrophoretic part. At the same time, the stepped cutting edge 41 can adapt to shielding holes of different diameters and perform rework, thereby greatly improving the rapid rework of shielding holes.

[0036] Preferably, in actual factory testing, the tungsten carbide blade body 4 of this application solves the problem of the inability to quickly repair the paint on the edge of the hole, while the tolerance range of the paint surface after repair can be fully guaranteed. At the same time, the overall repair operation is simple, requiring only holding the quick-release component 1 and rotating the tungsten carbide blade body 4 one revolution. It does not require the skill of the repair personnel, and the overall operation is highly expandable. For shielding holes of different diameters, it is only necessary to quickly replace the tungsten carbide blade body 4 of different sizes.

[0037] Furthermore, in practical use, through the mutual movement and cooperation of multiple structures set within the quick-release assembly 1, the quick-release assembly 1 can quickly clamp positioning rods 2 of different lengths. By clamping and installing the positioning rods 2, the user can quickly replace positioning rods 2 of different lengths within the quick-release assembly 1. Thus, by replacing the positioning rods 2, the processing position of the tungsten carbide blade body 4 can be changed according to requirements. For example, when reworking shielding holes in different positions, a positioning rod 2 with a longer dimension allows the tungsten carbide blade body 4 to better approach the shielding hole and rotate it to remove paint. At the same time, a positioning rod 2 with a longer dimension allows the operator to better grip the quick-release assembly 1 and control the rotation of the positioning rod 2.

[0038] It should be noted that the tungsten carbide blade body 4 can be quickly installed and removed from the positioning rod 2 through the plug-in connection between the positioning rod 2 and the tungsten carbide blade body 4. When the tungsten carbide blade body 4 is worn, the user can choose to install a new tungsten carbide blade body 4 and plug it back into the positioning rod 2. At the same time, the two sets of bolts 3 are passed through the positioning rod 2 in sequence and inserted into the tungsten carbide blade.

[0039] Second embodiment;

[0040] Reference Figure 2-3 As shown, the other ends of several clamping pieces 15 are fixedly disposed with a positioning ring 13; several positioning grooves 14 are formed around the center of the positioning ring 13. The positioning ring 13 is installed in the outer sleeve 11 by plugging in, so that the positioning ring 13 can be quickly removed and replaced from the outer sleeve 11.

[0041] Third embodiment;

[0042] Reference Figure 2-3 As shown, the inner bottom wall of the outer sleeve 11 has a plurality of protruding inserts 12 protruding around its center. The inserts 12 correspond sequentially to the positioning grooves 14 and are inserted into each other. The inserts 12 can be used to fit into the positioning grooves 14, so that the positioning ring 13 can be inserted and installed inside the outer sleeve 11.

[0043] Fourth embodiment;

[0044] Reference Figure 2-3As shown, the inner wall of the top of the outer sleeve 11 is provided with a second thread 19, and the outer side of the adjusting cylinder 16 is provided with a first thread 17. The first thread 17 and the second thread 19 are threadedly engaged. Through the threaded engagement between the first thread 17 and the second thread 19, the adjusting cylinder 16 can rotate within the outer sleeve 11.

[0045] Fifth embodiment;

[0046] Reference Figure 2 As shown, the angle of the inner conical surface 18 on the inner wall of the adjusting cylinder 16 is adapted to the conical surface of the clamping piece 15, and the inner conical surface 18 can surround several clamping pieces 15. When the adjusting cylinder 16 enters the outer sleeve 11, the inner conical surface 18 will gradually come into contact with the clamping pieces 15. Through the adaptation of the conical curvature of the inner conical surface 18 to the clamping pieces 15, the inner conical surface 18 can gradually surround several clamping pieces 15, thereby gradually tightening the several clamping pieces 15.

[0047] Furthermore, by adjusting the depth of the inner conical surface 18, the user can lock the positioning rod 2 with several clamping plates 15. Similarly, when the inner conical surface 18 moves away from the clamping plates 15, the clamping plates 15 will be in a relaxed state.

[0048] Sixth embodiment;

[0049] Reference Figure 1-3 As shown, a gripping rod 111 is fixedly installed on the top of the adjusting cylinder 16, and a gripping groove 110 is provided on the outside of the outer sleeve 11. The gripping rod 111 on the top of the adjusting cylinder 16 can be used to rotate the adjusting cylinder 16. At the same time, when the user holds the gripping groove 110, the positioning rod 2 can be quickly rotated, so that the positioning rod 2 can drive the tungsten carbide blade body 4 to rotate and complete the repair of the shielding hole.

[0050] Specific implementation process:

[0051] Step 1: When the user needs to install the tungsten carbide blade body 4, first select a positioning rod 2 of appropriate length and insert it into the insertion hole 131. At the same time, make the positioning rod 2 pass through the insertion hole 131 and several clamping pieces 15. At this time, the clamping pieces 15 will surround the outside of the positioning rod 2 and enclose it. Then, the user holds the outer sleeve 11 and rotates the holding rod 111. At this time, the adjusting cylinder 16 connected to the holding rod 111 will rotate synchronously. When the adjusting cylinder 16 rotates, the adjusting cylinder 16 can gradually enter into the outer sleeve 11 through the threaded engagement between the first thread 17 and the second thread 19.

[0052] Step 2: When the adjusting cylinder 16 enters the outer sleeve 11, the inner conical surface 18 will gradually come into contact with the clamping piece 15. Through the matching of the conical arc of the inner conical surface 18 with the clamping piece 15, the inner conical surface 18 can gradually surround several clamping pieces 15, so that several clamping pieces 15 can gradually tighten until the positioning rod 2 is clamped. At this time, the user can lock the positioning rod 2 by adjusting the inward stroke of the inner conical surface 18.

[0053] Step 3: After the positioning rod 2 is locked in the quick-release assembly 1, the user inserts the tungsten carbide blade body 4 into the rectangular groove at the bottom of the positioning rod 2. Then, the two sets of bolts 3 are passed through the threaded holes on the positioning rod 2. The two sets of bolts 3 will pass through the tungsten carbide blade body 4 and position it, preventing it from falling off the positioning rod 2. The simultaneous insertion of the two sets of bolts also prevents the tungsten carbide blade body 4 from rotating. The user then inserts the tungsten carbide blade body 4 at the bottom of the positioning rod 2 into the shielding hole of the electrophoresis component. The stepped design of the tungsten carbide blade body 4 and the stepped cutting edges 41 on both sides allow the tungsten carbide blade body 4 to adapt to shielding holes of different diameters. When the stepped cutting edges 41 on the tungsten carbide blade body 4 contact the shielding hole, the user rotates the tungsten carbide blade body 4 one turn. Through the contact between the stepped cutting edges 41 and the shielding hole, the excess paint on the shielding hole will be scraped off. After the repair is completed, a standard paint-free surface will be formed around the shielding hole.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
