Description

Technical Field

[0001] This utility model relates to the field of motor housing processing technology, and in particular to a hoisting and transfer tooling for motor housing processing. Background Technology

[0002] Currently, during the processing of motor housings, a transfer device is needed to move the motor housing to the corresponding workstation. Some motor housings have pre-drilled suspension holes for connection with hooks, which facilitates motor hoisting. However, motor housings without suspension holes are inconvenient for hoisting. Therefore, a hoisting fixture for motor processing is designed to facilitate the hoisting of motors without suspension holes. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a hoisting and transfer fixture for machining motor housings.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A hoisting and transfer fixture for machining motor housings includes a transfer frame, on both sides of which multiple support blocks are installed. A support arm is vertically fixed to one side of each support block, and a limit frame is fixed to the other side. A rubber rod is rotatably mounted on the bottom of the support arm via a rotating seat. A bushing is installed inside the rubber rod, and a slider is installed inside the bushing for limiting. One side of the slider is connected to the inner wall of the bushing via a spring, and the other side is connected to a hook via a chain. After being removed, the hook is hooked onto the crossbar on the limiting frame.

[0005] In addition, a preferred configuration is that the bottom of the transfer frame is equipped with self-locking casters.

[0006] Furthermore, a preferred structure is that multiple crossbars are installed in the middle of the limiting frame.

[0007] Furthermore, in a preferred configuration, the slider slides along the inner wall of the bushing to achieve lateral displacement.

[0008] Furthermore, a preferred structure is that the middle part of the rubber rod is concave and has an arc-shaped structure.

[0009] In addition, a preferred structure is that a limiting rod is provided below the rotating seat.

[0010] The beneficial effects of this utility model are as follows: In this utility model, the closed-loop hoisting structure composed of rubber rods, chains, hooks, and crossbars can achieve hoisting by passing through the motor housing without dedicated hoisting holes. At the same time, the hooks can be freely picked up and put down, hooked, and reset and stored in the rubber rods under the action of springs, effectively improving hoisting efficiency and ensuring hoisting stability.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figure 1-5 A hoisting and transfer fixture for processing motor housing includes a transfer frame 1, with multiple support blocks 2 installed on both sides of the transfer frame 1. A support arm 4 is vertically fixed to one side of the support block 2, and a limit frame 3 is fixed to the other side. A rubber rod 5 is rotatably mounted on the bottom of the support arm 4 via a rotating seat 51. A bushing 53 is installed inside the rubber rod 5. A slider 55 is installed inside the bushing 53 for limiting. One side of the slider 55 is connected to the inner wall of the bushing 53 via a spring 54, and the other side is connected to the hook 6 via a chain 56. After the hook 6 is removed, it is hooked onto the crossbar 31 on the limiting frame 3.

[0015] The rubber rod 5 has a groove in the middle to accommodate the bushing 53. One end of the bushing 53 narrows inward, which limits the movement of the slider 55 while ensuring its normal range of motion and preventing it from detaching. This structure is a conventional design in the field and will not be described in detail.

[0016] The bottom of the transfer frame 1 is equipped with self-locking casters 7 to enable the transfer frame 1 to move. The self-locking caster wheel 7 is readily available on the market and is a standard accessory in this field. Its specific structure and installation process are common knowledge to those skilled in the art.

[0017] The limiting frame 3 has multiple crossbars 31 in the middle, and each crossbar is designed to form a stable hook connection with the hook 6 to achieve reliable fixation of the suspension system.

[0018] The slider 55 slides on the inner wall of the bushing 53 to achieve lateral displacement.

[0019] The middle part of the rubber rod 5 is concave and has an arc-shaped structure.

[0020] A limiting rod 52 is provided below the rotating seat 51 to limit the lowest rotation position (angle) of the rotating seat 51 and prevent it from swinging down excessively. This is easy to understand intuitively and will not be explained further.

[0021] In this embodiment, the operator pushes the transfer frame 1 and moves the equipment to the target workstation using the self-locking casters 7 at its bottom. The operator then adaptively rotates and adjusts the rubber rod 5 as needed, inserts the rubber rod 5 into the motor housing, and passes it out from the other end.

[0022] Then pull the hook 6 on the side of the rubber rod 5. After the hook 6 extends, it is securely hooked onto the crossbar 31 of the limit frame 3, forming a complete hoisting system.

[0023] In practical applications, the rubber rod 5, due to its flexible material properties, can effectively avoid damaging the motor housing, and the internal bushing 53 can provide support while allowing the internal slider 55 to slide, so as to meet the needs of the hook 6 for picking up and putting down. During the lifting and lowering process, the hook 6 will drag the slider 55 to move via the chain 56, and the slider 55 will simultaneously pull the spring 54 to deform and stretch. Then, after the hook 6 is removed from the crossbar 31, the spring 54 deforms to drive the chain 56 and the hook 6 to reset, causing the hook 6 to cover the side wall of the rubber rod 5 again.

[0024] Chain 56 provides hook 6 with greater degree of adjustment freedom.

[0025] The closed-loop hoisting structure composed of rubber rod 5, chain 56, hook 6, and crossbar 31 forms a stable hoisting system, which can hoist motor housings without dedicated hoisting holes.

[0026] Its flexible connection structure ensures load-bearing capacity while effectively avoiding structural damage to the shell caused by traditional rigid hoisting.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
