Technical Field

[0001] The utility model relates to the technical field of metal parts spraying operation, in particular to a rotary hanger for parts spraying. Background Art

[0002] There are many metal parts in a car, and these parts are usually hung on a spray hanger for spraying. Most of the existing hangers suspend the parts in the air by hooks. Since the hooks cannot completely fix the parts during hanging, the parts may shake, so the spraying is easily uneven due to the shaking of the parts during spraying.

[0003] According to a publicly disclosed rotating hanger for spraying automobile parts (Announcement No.: CN108816582B), in the above application, an electromagnet is provided on the hanger, and the ferromagnetic metal parts can be fixed by the electromagnet when in use. The second bracket has two fulcrums for supporting the parts, which can fix the ferromagnetic metal parts firmly together with the electromagnet.

[0004] However, in actual use of the above equipment, since the spray hanger is generally placed on the rotating shaft of the driving device after hanging the parts, the hanger is driven to rotate slowly, and the parts hung on the hanger are easily offset and tilted outward due to the centrifugal force generated by the rotation, which in turn affects the stable spraying effect of the parts on the hanger; in view of this, we propose a rotary hanger for parts spraying. Utility Model Content

[0005] The utility model aims to provide a rotary hanger for parts spraying to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a rotary hanger for spraying parts, comprising a base, a vertical rod fixedly mounted on the upper surface of the base, a hanging rod detachably connected to the arc-shaped outer wall of the vertical rod, a limit assembly is arranged on the outer wall of the hanging rod, and the limit assembly comprises:

[0007] A positioning ring, a positioning ring is sleeved on the arc-shaped outer wall of the hanging rod, an inner rotating ring is rotatably installed on the side wall of the positioning ring, an elastic telescopic rod is fixedly connected to the arc-shaped outer wall of the inner rotating ring, and the top end of the elastic telescopic rod is movably connected to a limit ring;

[0008] A rotating rod, a swing groove is provided on the arc-shaped outer wall of the limiting ring, a rotating rod is rotatably installed on the inner wall of the swing groove, a clamping block passes through the rotating rod, and the clamping block is fixedly connected to the rotating rod, a volute spring is sleeved on the arc-shaped outer wall of the rotating rod, and a drainage groove is provided on the outer wall of the clamping block close to the positioning ring.

[0009] Preferably, there are two groups of inner swivel rings and limit rings, and the two groups of inner swivel rings and limit rings are mirror-imaged on the left and right sides of the positioning ring, thereby limiting the position of the automobile parts in the horizontal direction.

[0010] Preferably, an inclined surface is provided on the outer wall of the clamp block on one side close to the positioning ring, so as to guide the spraying material and also facilitate the staff to move the clamp block to install and remove automobile parts.

[0011] Preferably, the drainage groove is arranged in a wave shape to increase the gap size of the drainage groove, thereby reducing the contact area with the automobile parts while ensuring the limiting effect of the clamping block on the automobile parts.

[0012] Preferably, a lever assembly is provided on the outer wall of the positioning ring, the lever assembly includes a convex ring, a convex ring is provided on the arc-shaped outer wall of the positioning ring, and an arc-shaped plate is connected to the arc-shaped outer wall of the convex ring.

[0013] Preferably, the end of the arc plate is hinged to the limit ring through a retractable thin rod, and the hinge part between the convex ring and the arc plate is located at the center of the arc plate, so that when the vertical rod rotates and the automobile parts are affected by centrifugal force and deflected, its outer wall will drive the arc plate to deflect.

[0014] Compared with the prior art, the utility model provides a rotary hanger for parts spraying, which has the following beneficial effects:

[0015] 1. The rotating parts spraying hanger is provided with a limit assembly, and the base and the vertical pole are driven to rotate by an external driving device. Under the action of centrifugal force, the automobile parts will deflect left and right on the positioning ring. At this time, through the setting of the clamping block, the automobile parts will not be separated from the positioning ring even if they are deflected. In addition, since the inner rotating ring and the limit ring are integrally connected to the positioning ring, the combination of the automobile parts and the inner rotating ring and the limit ring will rotate slightly relative to each other during the rotation of the vertical pole, so that the contact part of the automobile parts can obtain a better spraying effect, thereby improving the spraying efficiency of the device.

[0016] 2. The rotary hanger for parts spraying is provided with a lever assembly. When the vertical rod rotates and the automobile parts are deflected by the centrifugal force, the outer wall of the lever will drive the arc plate to deflect, thereby causing the arc plate to form a lever effect to lift the limit ring on one side of the positioning ring and expand the size of the blocking area of ​​the limit ring, thereby effectively preventing the automobile parts placed on the hanging rod from detaching during rotary spraying, thereby ensuring the spraying operation effect of the device.

[0026] Furthermore, threaded holes are provided on the arc-shaped outer wall of the vertical pole 2, and threads matching the threaded holes are provided on the end outer wall of the hanging rod 3, so that the hanging rod 3 can be installed on the vertical pole 2 according to operational requirements. At the same time, a plurality of threaded holes are provided on the arc-shaped outer wall of the vertical pole 2, and three threaded holes are grouped in a circular array evenly distributed on the arc-shaped outer wall of the vertical pole 2. At the same time, multiple groups of threaded holes are arranged on the outer wall of the vertical pole 2 in a linear array in the vertical direction.

[0027] In addition, the positioning ring 41 is fixed to the hanging rod 3, so that the hanging rod 3 and the positioning ring 41 will not rotate relative to each other. At the same time, there are two groups of inner rotating rings 42 and limiting rings 44, and the two groups of inner rotating rings 42 and limiting rings 44 are mirror-imaged on the left and right sides of the positioning ring 41, so as to limit the automobile parts in the horizontal direction to prevent them from falling off the hanging rod 3. Specifically, the elastic telescopic rod 43 is movably connected to the limiting ring 44, so that the limiting ring 44 can perform eccentric movement on the outside of the inner rotating ring 42. Furthermore, there are multiple groups of swing grooves and clamping blocks 46, and the multiple groups of swing grooves and clamping blocks 46 are evenly distributed in a circular array on the arc of the limiting ring 44. shaped outer wall to enhance the limiting effect of the limiting ring 44 on the side of the automobile parts. At the same time, circular grooves with a diameter larger than the outer diameter of the spiral spring 47 are opened on the inner walls on both sides of the swing groove, and the two ends of the spiral spring 47 are respectively fixedly connected to the bottom inner wall of the circular groove and the arc-shaped outer wall of the rotating rod 45, so that when the rotating rod 45 drives the clamping block 46 to rotate, it always has a movement tendency of reverse rotation to achieve reset, and in the initial state, due to the elastic force limitation of the spiral spring 47, the rotating rod 45 always has a movement tendency of driving the clamping block 46 to deflect toward the side of the positioning ring 41, so that the clamping block 46 can effectively limit the automobile parts sleeved on the outside of the positioning ring 41.

[0028] Specifically, there are multiple groups of drainage grooves 48, and the multiple groups of drainage grooves 48 are evenly distributed in a linear array on the outer wall of the clamp block 46 close to the center of the positioning ring 41, and an inclined surface is provided on the outer wall of the clamp block 46 close to the positioning ring 41, so as to guide the spraying material, and at the same time, it is convenient for the staff to bend the clamp block 46 to install and remove the automobile parts, thereby improving the processing effect of the device. At the same time, the drainage grooves 48 are arranged in a wave shape to increase the gap size of the drainage grooves 48, while ensuring the limiting effect of the clamp block 46 on the automobile parts, reducing the contact area with the automobile parts, thereby improving the spraying processing efficiency of the automobile parts. Further, the automobile When the automobile parts are sleeved on the outside of the positioning ring 41, the base 1 and the vertical rod 2 are driven to rotate by an external driving device. Under the action of centrifugal force, the automobile parts will deflect left and right on the positioning ring 41. At this time, through the setting of the clamping block 46, the automobile parts will not be separated from the positioning ring 41 even if they are deflected. In addition, since the inner rotating ring 42 and the limiting ring 44 are rotationally connected to the positioning ring 41 as a whole, the combination of the automobile parts, the inner rotating ring 42 and the limiting ring 44 will rotate slightly relative to each other during the rotation of the vertical rod 2, so that the contact part of the automobile parts can obtain a better spraying effect, thereby improving the spraying efficiency of the device.

[0029] In the embodiment of the utility model, a lever assembly 5 is provided on the outer wall of the positioning ring 41, and the lever assembly 5 includes a convex ring 51. A convex ring 51 is opened on the arc-shaped outer wall of the positioning ring 41, and an arc plate 52 is intersected on the arc-shaped outer wall of the convex ring 51. Specifically, the outer wall of the end of the arc plate 52 is movably connected to the inner wall of the limiting ring 44. Specifically, the end of the arc plate 52 is hinged to the limiting ring 44 through a retractable thin rod, and the hinge part between the convex ring 51 and the arc plate 52 is at the center of the arc plate 52. Therefore, when the vertical pole 2 rotates and the automobile parts are affected by the centrifugal force and deflected, its outer wall will drive the arc plate 52 to deflect, thereby prompting the arc plate 52 to form a lever effect, so as to lift the limiting ring 44 on one side of the positioning ring 41 and expand the size of the blocking area of ​​the limiting ring 44, thereby effectively preventing the automobile parts placed on the hanging rod 3 from being separated during rotary spraying, thereby ensuring the spraying operation effect of the device.

[0030] In the utility model, when in use, the staff first bends the clamping block 46 on the limiting ring 44 away from the side of the vertical pole 2 outward, so that the hole of the automobile part can pass through the limiting ring 44 and enter the outside of the positioning ring 41, and then releases the clamping block 46. Under the elastic force of the spiral spring 47, the limiting rings 44 on the left and right sides of the positioning ring 41 and their corresponding clamping blocks 46 will limit the automobile parts in the horizontal direction. After that, the automobile parts are hung on the hanging rod 3 on the outside of the vertical pole 2 in turn according to the above method, and then the base 1 is connected with the driving shaft of the external driving device, and the driving device is started to cooperate with the rotation of the driving shaft and the base 1 to drive the vertical pole 2 to rotate, and at the same time, the spraying equipment is started to spray the automobile parts placed on the hanging rod 3.
