Description

Technical Field

[0001] This utility model relates to the field of spray painting hanger technology, and in particular to a spray painting hanger based on magnetic force to restrict the rotation of small workpieces. Background Technology

[0002] In the field of automated spraying of small workpieces (such as motor housings, small metal shells, and other workpieces with lifting points), in order to achieve efficient and continuous spraying operations, a suspended conveyor line is often used in conjunction with a lifting device to complete the transport and spraying of the workpieces. However, due to their light weight and single lifting point, small workpieces are prone to circumferential rotation during transport, resulting in chaotic posture during spraying, uneven spraying coverage, inconsistent thickness, and seriously affecting the appearance quality and protective performance of the finished product.

[0003] Small workpieces are lightweight and have a single lifting point. Existing lifting devices cannot effectively limit their circumferential rotation during transportation, resulting in inconsistent spraying posture, which directly affects the uniformity of spraying and the quality of finished products. At the same time, rigid limit lifting devices have poor compatibility and are prone to missed spraying; lifting devices without active limit devices have unstable posture; lifting devices with fixed magnetic components cannot be adjusted flexibly, and it is difficult to hang and pick up workpieces, resulting in extremely low efficiency in production changeover and daily operation. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that the lifting device cannot effectively limit the circumferential rotation of the workpiece during the transportation process, resulting in inconsistent spraying posture and directly affecting the uniformity of spraying and the quality of the finished product. Therefore, this invention proposes a spraying lifting device based on magnetic force to limit the rotation of small workpieces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a spraying hanger based on magnetic force to restrict the rotation of small workpieces, comprising a hanging plate, a U-shaped iron plate at the bottom of the hanging plate, a disk at the bottom of the U-shaped iron plate, a convex screw penetrating through the center of the disk and the U-shaped iron plate, a screw groove at the bottom of the hanging plate near the center, the top of the convex screw being embedded in the screw groove and threadedly connected thereto, a convex plate inside the U-shaped iron plate, a fixing plate fixedly connected to the bottom of the convex plate, a square hole on the surface of the fixing plate, a V-shaped plate hanging inside the square hole, and a hook fixedly connected to the bottom of the V-shaped plate.

[0006] Preferably, the surface of the mounting plate has a circular hole.

[0007] Preferably, the bottom of the convex screw is provided with a cross groove.

[0008] Preferably, the two ends and near the sides of the U-shaped iron plate are chamfered, and the four corners of the fixing plate are chamfered.

[0009] Preferably, two circular grooves are formed at both ends of the convex plate, and through holes are formed on both side walls of the U-shaped iron plate, with the through holes aligned with the circular grooves.

[0010] Preferably, one end of the V-shaped plate is longer than the other end.

[0011] Preferably, a motor housing is attached to the surface of the hook.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the magnetic attraction of the disk to the U-shaped iron plate, combined with the synergy of the convex plate, the fixing plate and other structures, can stably restrict the circumferential rotation of small workpieces, ensure the consistent posture of the workpieces during the spraying process, and greatly improve the uniformity of spraying.

[0013] 2. In this utility model, the V-shaped plate can be easily hung through the square hole, which can adapt to small workpieces of different shapes and sizes; the magnetic connection between the disk and the U-shaped iron plate, and the thread adjustment of the convex screw, can flexibly adjust the position and range of the magnetic force to meet the limiting requirements of various workpieces.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1, such as Figure 1-7 As shown, this utility model provides a spraying hanger based on magnetic force to restrict the rotation of small workpieces, including a hanging plate 1, a U-shaped iron plate 7 at the bottom of the hanging plate 1, a disk 6 at the bottom of the U-shaped iron plate 7, a convex screw 4 passing through the center of the disk 6 and the U-shaped iron plate 7, a screw groove 3 at the bottom of the hanging plate 1 near the center, the top of the convex screw 4 being embedded in the screw groove 3 and threadedly connected to it, a convex plate 8 inside the U-shaped iron plate 7, a fixing plate 11 fixedly connected to the bottom of the convex plate 8, a square hole 12 on the surface of the fixing plate 11, a V-shaped plate 13 hanging inside the square hole 12, and a hook 14 fixedly connected to the bottom of the V-shaped plate 13.

[0020] The overall effect of embodiment 1 is as follows: a U-shaped iron plate 7 is provided at the bottom of the hanging plate 1, a disk 6 is provided at the bottom of the U-shaped iron plate 7, and a convex screw 4 passes through the center of the disk 6 and the U-shaped iron plate 7. This allows the convex screw 4 to pass through the disk 6 and the U-shaped iron plate 7 and be embedded in the screw groove 3, thus fixing the disk 6 and the U-shaped iron plate 7. A screw groove 3 is provided at the bottom of the hanging plate 1 near the center. The top of the convex screw 4 is embedded in the screw groove 3 and threadedly connected to it, thus screwing the convex screw 4 into the screw groove 3. A convex plate 8 is provided inside the U-shaped iron plate 7. A fixing plate 11 is fixedly connected to the bottom of the convex plate 8. A square hole 12 is provided on the surface of the fixing plate 11. A V-shaped plate 13 is hung inside the square hole 12. A hook 14 is fixedly connected to the bottom of the V-shaped plate 13, thus hanging the V-shaped plate 13 in the square hole 12.

[0021] Example 2, as Figure 1-7As shown, the surface of the hanging plate 1 has a round hole 2; the bottom of the convex screw 4 has a cross groove 5; both ends and near the sides of the U-shaped iron plate 7 are chamfered, and the four corners of the fixing plate 11 are also chamfered; both ends of the convex plate 8 have two round grooves 10, and both sides of the U-shaped iron plate 7 have through holes 9, which are aligned with the round grooves 10; one end of the V-shaped plate 13 is longer than the other end; and the surface of the hook 14 is covered with a motor cover 15.

[0022] The overall effect of embodiment 2 is as follows: the circular holes 2 on the surface of the hanging plate 1 provide an installation interface for the lifting device; the cross grooves 5 at the bottom of the convex screw 4 facilitate rotation of the convex screw 4; the chamfered ends and near the sides of the U-shaped iron plate 7, and the chamfered corners of the fixing plate 11 prevent the sharp corners of the U-shaped iron plate 7 and the fixing plate 11 from injuring the installer; the two circular grooves 10 at both ends of the convex plate 8, and the through holes 9 on both sides of the U-shaped iron plate 7, which are aligned with the circular grooves 10, facilitate the installation and fixation of the convex plate 8; the V-shaped plate 13, with one end longer than the other, facilitates hanging the V-shaped plate 13 on the square hole 12; and the motor cover 15 is hung on the surface of the hook 14, allowing the motor cover 15 to be held in place.

[0023] Working principle: First, the entire hanger is installed at the designated position on the suspended conveyor line through the round hole 2 on the surface of the hanging plate 1; then, a tool is inserted into the cross groove 5 at the bottom of the convex screw 4 and rotated, so that the top of the convex screw 4 is screwed in or out along the screw groove 3 of the hanging plate 1, adjusting the distance between the disk 6 and the U-shaped iron plate 7, thereby adjusting the magnetic attraction force (the distance is reduced to enhance the magnetic force when strong limiting is required, and the distance is increased when flexible operation is required); next, the convex plate 8 is embedded into the U-shaped iron plate 7, so that the through holes 9 on both sides of the U-shaped iron plate 7 are aligned with the round groove 10 of the convex plate 8 (pins can be inserted to strengthen the connection stability, or the magnetic attraction and structural cooperation can be relied upon to maintain it); then, according to the shape and size of the workpiece to be sprayed, a suitable V-shaped plate 13 is selected and hung in the square hole 12 of the fixing plate 11 (using... The V-shaped plate 13, with one end longer than the other, is used to stably suspend the workpiece within the square hole 12. Then, the workpiece is hung on the hook 14 via its own suspension point. At this time, the disk 6 exerts a magnetic attraction on the U-shaped iron plate 7, restricting the circumferential rotation of the U-shaped iron plate 7, the convex plate 8 below, the fixed plate 11, the V-shaped plate 13, the hook 14, and the workpiece, ensuring the workpiece's stable posture when transported to the spraying area. When it is necessary to change the workpiece or adjust the hanger, the magnetic attraction of the disk 6 to the U-shaped iron plate 7 can be released (or the magnetic force can be directly overcome), and the V-shaped plate 13 can be removed, quickly completing the hanging and retrieval of the workpiece or the replacement of the V-shaped plate 13, making operation convenient. During the spraying process, the stable posture allows the spraying equipment to uniformly and completely spray the workpiece surface, avoiding problems such as missed spraying or uneven spraying caused by rotation. The wiring diagram of disk 6 in this utility model is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to actual use, so the control method and wiring layout of disk 6 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
