DETAILED DESCRIPTION

[0023] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present invention.

[0024] See also Figure 1-6 An embodiment of the present invention is as follows: a hanger for blind hole workpieces, comprising a hanger body 2; the hanger body 2 comprises a fixed frame 25 and a movable frame 26 that slides upward or downward on the fixed frame 25; the fixed frame 25 is also provided with a hook 27 for hanging the workpiece, and the movable frame 26 is provided with a lifting rod 28, and the movable frame 26 slides upward on the fixed frame 25 to allow the lifting rod 28 to flip the workpiece on the hook 27; the fixed frame 25 is provided with a first hook body 29, and the movable frame 26 is also provided with a second hook body 210, and the second hook body 210 is in contact with the facing surface of the first hook body 29, and the second hook body 210 is guided to slide through a limiting portion 211 provided on the first hook body 29.

[0025] To summarize, when the workpiece is placed on the hook 27 with the side with the blind hole facing outward, and then the movable frame 26 is lifted upward, the lifting rod 28 on the movable frame 26 is in contact with one side of the workpiece. As the lifting rod 28 continues to move upward, the workpiece can be flipped on the hook 27, thereby facilitating the pouring out of the liquid inside the blind hole of the workpiece; for example, the workpiece is a car caliper, the front of the caliper is placed in the bending area in front of the hook 27, and the rear end is placed in the straight area of ​​the hook 27. When the U-shaped lifting rod 28 moves upward, the rear end of the car caliper moves upward with the lifting rod 28, and the front of the car caliper rotates in the bending area under the action of its own weight, so that the liquid inside the blind hole of the car caliper can be poured out.

[0026] Based on this, users only need to hang the product on the hanger body, and there is no need to block the blind holes; while improving production efficiency, the workload and number of workers are greatly reduced.

[0027] At the same time, the limiting part 211 is used to guide the directional sliding, that is, the movable frame 26 can only slide upward or downward along the vertical direction of the fixed frame 25, so as to ensure the smooth pouring of the liquid while avoiding the phenomenon of the workpiece falling due to the left and right swinging of the fixed frame and the movable frame.

[0028] On the basis of the above scheme, a lifting assembly is further provided above the hanger body 2, and the lifting assembly includes a fixed beam 23 and a movable beam 21; wherein the first hook 29 is fixed on the fixed beam 23, and the second hook 210 is fixed on the movable beam 21. In summary, since the fixed frame 25 is fixed by the fixed beam 23 and moved by the movable beam 21, the movable frame 26 can slide on the fixed frame 25 as a whole, and in particular, the movable frame 26 can be driven by the movable beam 21 to move upward or downward synchronously on the fixed frame 25.

[0029] Furthermore, since both ends of the fixed beam 23 are provided with guide seats 22, and both ends of the movable beam 21 are provided with lifting hooks 20 sliding in the guide seats 22, the guide seats 22 can be used to guide the directional sliding of the lifting hooks 20, so that the movable frame 26 can move upward or downward more stably and reliably.

[0030] Furthermore, since a support beam 24 is also provided on the guide seat 22, when the two guide seats 22 are installed on the support beam 24, it can be ensured that the two guide seats 22 have sufficient structural strength. At the same time, the moving distance of the movable beam 21 is limited by the support beam 24, so the moving distance of the lifting hook 20 can be limited to avoid the workpiece falling from the hook 27 due to excessive movement of the lifting hook 20.

[0031] In addition, since the material of the fixed beam 23 is copper plate, the fixed beam 23 not only plays a supporting and fixing role, but also facilitates connection with the cathode. Therefore, the device can ensure the smoothness of the circuit while preventing the movable frame 26 from being difficult to move smoothly due to the wire dragging and hooking the movable frame 26.

[0032] In order to realize the automatic upward movement of the movable frame 26, the device moves the hook 1 upward to promote the upward movement of the lifting hook 20. That is, when the hook 1 is hooked on the lifting hook 20, as the hook 1 continues to move upward, the movable frame 26 can be driven to move upward, thereby promoting the workpiece to flip on the hook 27. In summary, the liquid inside the workpiece can be poured out while the device is lifted out of the electroplating tank by the hook 1. Based on this, the lifting efficiency of the workpiece can be improved while the movable frame 26 is automatically lifted.

[0033] Furthermore, a vertical rod 212 for mounting the lifting rod 28 is provided in the vertical direction of the movable frame 26, and a horizontal rod 213 for mounting the hook 27 is provided in the horizontal direction of the fixed frame 25. The number of the vertical rods 212 is multiple, and they are evenly spaced along the height direction of the movable frame 26, and the number of the lifting rods 28 is multiple, and they are evenly spaced along the height direction of the lifting rods 28; the number of the horizontal rods 213 is multiple, and they are evenly spaced along the height direction of the fixed frame 25, and the number of the hooks 27 is multiple, and they are evenly spaced along the length direction of the horizontal rod 213.

[0034] Through the above scheme, multiple lifting rods 28 can be distributed on the entire movable frame 26, and multiple hooks can also be provided on the fixed frame 25, so that the combined movable frame 26 and fixed frame 25 can hang more workpieces at the same time, thereby further improving the electroplating effect of the workpieces.

[0035] Furthermore, since the fixed frame 25 is also provided with a guide groove 214 for guiding the vertical rod 212 to slide upward or downward, the entire movable frame 26 can move reliably and directionally, avoiding the movable frame 26 from getting stuck, stagnant or stuck due to misalignment with the fixed frame 25 when moving, and the workpiece from falling off when the movable frame 26 moves.

[0036] In addition, since both the first hook 29 and the second hook 210 are provided with a fastener 215; when one end of the fastener 215 passes through the first hook 29 and is connected to the fixed beam 23, the fixed frame 25 can be fixed to avoid poor contact of the circuit due to the shaking of the first hook 29. At the same time, the fastener 215 can be loosened to achieve the disassembly and assembly of the fixed frame 25; similarly, another fastener 215 is used to pass through the second hook 210 and then be connected to the moving beam 21 to fix the movable frame 26 on the moving beam 21; wherein the fastener 215 is preferably a knob with a screw.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
