Description

Technical Field

[0001] This application belongs to the field of surface treatment technology, and in particular relates to a hanger for surface treatment of sheet metal. Background Technology

[0002] Metal sheet metal components, as fundamental building blocks of modern industry, are widely used in many fields such as automobile manufacturing, aerospace, electronics and communications, and home appliances and furniture. Their surface treatment processes (such as spraying, electroplating, anodizing, phosphating, cleaning, and polishing) are crucial for improving the corrosion resistance, aesthetics, functionality, and added value of products.

[0003] During the surface treatment process, the sheet metal needs to be fixed on the rack first, and then the rack is placed into a special equipment for surface treatment. However, the existing fixtures on the racks are usually activated by a drive rod or button, which requires the operator to hold the sheet metal with one hand and operate the drive rod or button with the other, making the operation inconvenient. Utility Model Content

[0004] The purpose of this application is to provide a hanging rack for surface treatment of sheet metal, which aims to solve the problem of inconvenient operation when using existing hanging racks to clamp sheet metal.

[0005] This application embodiment is implemented as follows: a hanger for surface treatment of sheet metal, the hanger comprising:

[0006] The fixing frame has a fixing rod;

[0007] A rotating frame is rotatably mounted on the fixed rod, and the rotating frame rotates relative to the fixed rod to have a first position and a second position;

[0008] A clamping assembly is provided on the rotating frame, the clamping assembly including two clamping jaws that cooperate with each other;

[0009] A drive assembly includes a drive rack slidably disposed on the rotating frame. The drive rack and the clamping assembly are connected by a transmission assembly so that when the drive rack slides, it drives the two grippers to clamp or release the gripping action. A drive gear that meshes with the drive rack is rotatably disposed on the rotating frame. An eccentric wheel is fixedly disposed on the fixed rod. When the rotating frame rotates from the first position to the second position, the eccentric wheel abuts against the drive gear to drive the drive gear to rotate, thereby driving the two grippers to perform a clamping action.

[0010] A locking component for locking the rotating frame in a second position.

[0011] In some preferred embodiments of this application, an elastic element is provided between the drive gear and the rotating frame.

[0012] In some preferred embodiments of this application, the eccentric wheel is configured such that when the rotating frame is in the first position, the eccentric wheel does not abut against the drive gear, and when the rotating frame rotates from the first position to the second position, the eccentric wheel gradually abuts against the drive gear.

[0013] In some preferred embodiments of this application, the drive rack has an abutment portion located between the two grippers.

[0014] In some preferred embodiments of this application, a sliding rod is fixedly provided on the rotating frame, and the two grippers are slidably disposed on the sliding rod.

[0015] In some preferred embodiments of this application, the transmission assembly includes an intermediate shaft, and a first gear and a second gear fixedly disposed on the intermediate shaft. The intermediate shaft is rotatably disposed on the rotating frame. The gripper is provided with a rack portion. The first gear meshes with the rack portion, and the second gear meshes with the drive rack.

[0016] In some preferred embodiments of this application, the locking assembly includes a limiting member slidably disposed on the fixed rod, the limiting member having a limiting portion for abutting against the rotating frame, the limiting member sliding along the axial direction of the fixed rod so that the limiting portion enters or exits the rotation path of the rotating frame.

[0017] This application provides a hanging bracket for surface treatment of sheet metal. The sheet metal is placed between two grippers, and force is applied to it. This force is transmitted to a rotating frame, causing the frame to rotate from a first position to a second position. During rotation, an eccentric wheel abuts against a drive gear, driving the drive gear to rotate, which in turn drives the two grippers to perform a clamping action. This eliminates the need for the operator to use one hand to activate the clamping assembly, facilitating operation. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0030] The specific implementation of this application will be described in detail below with reference to specific embodiments.

[0031] like Figure 1 The diagram shown is a structural schematic of a hanging bracket for surface treatment of a plate 10 provided in an embodiment of this application, including: a fixed bracket 100, a rotating bracket 200, a clamping assembly 300, a driving assembly 400, and a locking assembly.

[0032] The mounting bracket 100 has a fixing rod 110 and is used to fix it on a transfer vehicle or directly inside the surface treatment equipment.

[0033] The rotating frame 200 is rotatably mounted on the fixed rod 110, and the rotating frame 200 rotates relative to the fixed rod 110 to have a first position and a second position. Specifically, Figure 1 The position shown is the second position, in which the clamping component 300 is in a vertical state. (Refer to...) Figure 1 From the perspective of the rotating frame 200, the rotating frame 200 rotates 90 degrees clockwise relative to the fixed rod 110 to reach the first position. In the first position, the clamping component 300 is in a horizontal state, and the clamping jaw of the clamping component 300 faces the horizontal direction, which makes it convenient for the operator to install the plate 10.

[0034] The clamping assembly 300 is disposed on the rotating frame 200, and the clamping assembly 300 includes two clamping jaws 310 that cooperate with each other.

[0035] like Figures 1 to 3As shown, the drive assembly 400 includes a drive rack 410 slidably disposed on the rotating frame 200. The drive rack 410 and the clamping assembly 300 are connected by a transmission assembly so that when the drive rack 410 slides, it drives the two grippers 310 to clamp or release. A drive gear 420 that meshes with the drive rack 410 is rotatably disposed on the rotating frame 200. An eccentric wheel 430 is fixedly disposed on the fixed rod 110. When the rotating frame 200 rotates from the first position to the second position, the eccentric wheel 430 abuts against the drive gear 420 to drive the drive gear 420 to rotate, thereby driving the two grippers 310 to perform a clamping action.

[0036] For details, see Figure 2 As shown, the drive rack 410 has a vertically oriented groove, and the rotating frame 200 is provided with a guide portion that cooperates with the groove. The drive rack 410 slides vertically under the cooperation of the guide portion and the groove. When the drive rack 410 slides upward, it drives the two grippers 310 to move towards each other through the transmission assembly to perform a clamping action. When the drive rack 410 slides downward, it drives the two grippers 310 to move away from each other through the transmission assembly to release the clamp.

[0037] See Figure 2 The rotating frame 200 is located in the second position, and a drive gear 420 that meshes with the drive rack 410 is rotatably mounted on the rotating frame 200. The outer periphery of the drive gear 420 abuts against the outer peripheral surface of the eccentric wheel 430. Figure 2 From this perspective, the rotating frame 200 needs to be rotated clockwise to the first position.

[0038] like Figure 1 As shown, the locking component is used to lock the rotating frame 200 in the second position.

[0039] In this embodiment, initially, the plate 10 is placed between the two grippers 310, and force is applied to the plate 10. The force is transmitted to the rotating frame 200, causing the rotating frame 200 to rotate from a first position to a second position. During the rotation, the eccentric wheel 430 abuts against the drive gear 420 to drive the drive gear 420 to rotate. Figure 2 As shown, the rotating frame 200 rotates counterclockwise from a horizontal first position to a vertical second position. The drive gear 420 rolls along the outer circumference of the eccentric wheel 430 to achieve counterclockwise self-rotation, which in turn drives the drive rack 410 to rise, causing the two grippers 310 to move towards each other, thus clamping and fixing the plate 10. This eliminates the need for the operator to use one hand to activate the clamping assembly 300, making operation convenient.

[0040] In this embodiment, an elastic element 440 is provided between the drive gear 420 and the rotating frame 200. Specifically, as shown... Figure 3 As shown, the elastic element 440 is a torsion spring, with one end fixed to the rotating frame 200 and the other end fixed to the drive gear 420. It can be understood that when the rotating frame 200 rotates from a horizontal first position to a vertical second position, the drive gear 420 rotates relative to the rotating frame 200, causing the elastic element 440 to accumulate elastic potential energy. When the locking assembly unlocks, the accumulated elastic potential energy causes the drive gear 420 to rotate. Since the drive gear 420 and the eccentric wheel 430 abut against each other, the rotating frame 200 automatically returns from the second position to the first position, and the two grippers 310 open, thus facilitating the next clamping of the plate 10.

[0041] In one embodiment of this application, the eccentric wheel 430 is configured such that when the rotating frame 200 is in the first position, the eccentric wheel 430 does not abut against the drive gear 420, and when the rotating frame 200 rotates from the first position to the second position, the eccentric wheel 430 gradually engages with the drive gear 420. This allows for convenient adjustment of the initial distance between the two grippers 310 in the first position.

[0042] In one example of this application, such as Figure 2 As shown, the drive rack 410 has an abutment portion 411 located between the two grippers 310. In this embodiment,

[0043] It is understandable that when the rotating frame 200 is in the first position, the eccentric wheel 430 and the drive gear 420 are not in contact, so under normal conditions, the rotating frame 200 cannot fully reach the first position. Therefore, in practical use, force can be applied to the plate 10 firstly to drive the rotating frame 200 to the first position, and then the abutment part 411 is pressed to move the drive rack 410 to the two grippers 310 to clamp the plate 10. Then, the rotating frame is rotated to the second position, and the grippers 310 are further clamped to the plate 10. In this embodiment, the grippers 310 are pre-clamped to the plate 10 first, so that the force can be transmitted from the plate 10 to the rotating frame 200, causing the rotating frame 200 to rotate to the second position.

[0044] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, a sliding rod 210 is fixedly mounted on the rotating frame 200, and two grippers 310 are slidably mounted on the sliding rod 210. In this embodiment, the sliding rod 210 guides the grippers 310, making the grippers 310 slide more smoothly.

[0045] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the transmission assembly includes an intermediate shaft 510, and a first gear 520 and a second gear 530 fixedly mounted on the intermediate shaft 510. The intermediate shaft 510 is rotatably mounted on the rotating frame 200. The gripper 310 is provided with a rack portion 540. The first gear 520 meshes with the rack portion 540, and the second gear 530 meshes with the drive rack 410. In this embodiment, gear transmission ensures the stability of motion transmission.

[0046] In some embodiments of this application, the locking assembly includes a limiting member 610 slidably disposed on the fixed rod 110, the limiting member 610 having a limiting portion 611 for abutting against the rotating frame 200, the limiting member 610 sliding along the axial direction of the fixed rod 110 so that the limiting portion 611 enters or exits the rotation path of the rotating frame 200.

[0047] Specifically, such as Figure 1 As shown, a spring is provided between the limiting member 610 and the fixing rod 110. The spring drives the limiting member 610 to slide axially along the fixing rod 110 so that the limiting part 611 enters the rotation path of the rotating frame 200. A handle is provided on the limiting member 610, which allows the operator to drive the limiting member 610 to slide until the limiting part 611 exits the rotation path of the rotating frame 200, thereby achieving contact locking.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
