Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a hook hanger for an electrophoretic paint production line. Background Art

[0002] In an electrophoretic paint production line, in order to ensure the coating quality of parts, workers usually use hook hangers to hang the parts to be processed to ensure the stability of the parts during the coating process. Existing hook hangers usually consist of a connecting rod and a hook.

[0003] For example: The utility model with application number CN202121166698.6 discloses a hanger for electrophoretic coating of automobile steering knuckle, specifically including a steering knuckle and a hook. There are two hooks, and the two hooks are hung in the steering knuckle. A circular hole one is provided on the surface of the two hooks, and a connecting frame is provided above the two hooks. The bottom surfaces of the two connecting frames are concave with rectangular grooves, and the surfaces of the two connecting frames are provided with circular hole two that matches the circular hole one. When in use, the steering knuckle is hung on the two hooks, and the lower ends of the hooks are arc-shaped to prevent the steering knuckle and the hook from falling off, making the hanging more stable. The contact area between the two hooks and the steering knuckle is small, so that the electrophoretic effect of the steering knuckle is better. Since the upper ends of the two hooks are respectively arranged in the rectangular grooves, each group of circular holes one and circular holes two are plugged with plug rods, and the two hooks can swing, which is convenient for the installation of the hooks and the steering knuckle, and the operation is relatively convenient.

[0004] However, as far as the current traditional hook hangers are concerned, the parts to be processed are usually hung on the hooks. But when the weight of the parts on the hooks is unevenly distributed, the hook hangers that move with the production line are likely to shake as the production line moves. When the shaking amplitude is too large, the parts are likely to fall from the hooks, causing damage to the parts to be processed and affecting the efficiency of electrophoretic coating. Utility Model Content

[0005] In view of this, the utility model provides a hook hanger for an electrophoretic paint production line, which has a limit baffle that can block the hook when the part is hung on the hook. Under the action of the part's own gravity, the part will press down the control block to flip the control block and squeeze the reset spring. After the control block is flipped, the limit on the movable wedge seat will be released. At this time, the movable wedge seat will move with the rebound of the fixed spring. During the movement of the movable wedge seat, the control wedge seat will be squeezed to move the control wedge seat upward and squeeze the auxiliary spring. During the movement of the control wedge seat, the control rack will be driven to move. As the control rack moves, the control gear meshed with it will be driven to rotate. As the control gear rotates, the control shaft will be driven to rotate, so that the control shaft drives the limit baffle to flip and block the suspension rod, thereby preventing the parts from falling from the suspension rod.

[0006] The utility model provides a hook hanger for an electrophoretic paint production line, which specifically includes: a hanger connecting rod; a fixed base is fixedly connected to the bottom end surface of the hanger connecting rod; two fixed rotating shafts are symmetrically and rotatably connected inside the fixed base; a group of suspension hanging rods are fixedly connected to the outside of the two fixed rotating shafts; a hanger sliding rod is slidably connected inside the hanger connecting rod; a connecting spring is fixedly connected to the lower part of the hanger sliding rod; the end of the connecting spring is fixedly connected inside the hanger connecting rod; a first incomplete screw rod is fixedly connected to the top end surface of the hanger sliding rod; a group of moving wedge seats are slidably connected inside the two groups of suspension hanging rods; inclined surfaces are arranged on the inner sides of the two groups of moving wedge seats.

[0007] Optionally, a hanger hook is fixedly connected to the top end surface of the first incomplete screw rod; an incomplete hanging ring is hingedly connected to the end of the hanger hook; a second incomplete screw rod is fixedly connected to the end of the incomplete hanging ring; a locking nut is threadedly connected to the outside of the first incomplete screw rod.

[0008] Optionally, a double-sided rack is fixedly connected to the bottom end surface of the hanger sliding rod; a transmission gear is fixedly connected to the outside of each of the two fixed rotating shafts; both transmission gears are meshed with the double-sided rack.

[0009] Optionally, control blocks are rotatably connected inside the two groups of suspension hanging rods; return springs are fixedly connected to the outer sides of the two groups of control blocks; the ends of the two groups of return springs are respectively fixedly connected to the outside of the two groups of suspension hanging rods; fixed springs are fixedly connected to the outer sides of the two groups of moving wedge seats; the two groups of control blocks are respectively clamped inside the two groups of moving wedge seats; the ends of the two groups of fixed springs are respectively fixedly connected to the inside of the two groups of suspension hanging rods; a group of control levers are fixedly connected to the outside of the two groups of moving wedge seats; the two groups of control levers are respectively slidably connected inside the two groups of suspension hanging rods.

[0010] Optionally, control wedge seats are slidably connected inside the two groups of suspension hanging rods; fixing plates are fixedly connected inside the two groups of suspension hanging rods; auxiliary springs are fixedly connected to the bottom end surfaces of the two groups of fixing plates; the ends of the two groups of auxiliary springs are respectively fixedly connected to the top end surfaces of the two groups of control wedge seats.

[0011] Optionally, control racks are fixedly connected to the top end surfaces of the two groups of control wedge seats; control rotating shafts are rotatably connected to the upper parts of the two groups of suspension hanging rods; a group of control gears are fixedly connected to the outside of the two groups of control rotating shafts; the two groups of control gears are respectively meshed with the two groups of control racks; a limit baffle is coaxially fixedly connected to the outside of the two groups of control rotating shafts.

[0012] Beneficial effects

[0013] When the hook hanger is hung on the electrophoresis paint production line, under the action of its own gravity, the hanger connecting rod will slide downward along the hanger sliding rod, and then drive the suspension boom to turn through a series of transmissions, which is convenient for hanging parts. After the hook hanger is removed, under the action of the elastic potential energy of the connecting spring, the hanger connecting rod will be reset, making the above movement reverse, automatically folding the suspension boom, reducing the space occupied by the hook hanger, facilitating the storage of the hook hanger, and effectively improving the convenience of the hook hanger.

[0014] When hanging a part on the suspension boom, under the action of the part's own gravity, the control block will be pressed down to make the control block turn, and then drive the control gear to rotate through a series of transmissions. As the control gear rotates, it will drive the control shaft to rotate, so that the control shaft drives the limit baffle to turn to block the suspension boom, preventing the part from falling off the suspension boom, improving the production efficiency of the part, ensuring the quality of the product, and effectively improving the practicality of the hook hanger.
