Description

Technical Field

[0001] The utility model relates to the technical field of waterproof bottom shell processing tooling, and more particularly, to a waterproof bottom shell processing tooling. Background Art

[0002] In the current field of waterproof bottom shell processing, the design and function of tooling equipment are crucial to improving production efficiency and processing quality. However, according to the description of the existing technology, these processing tools have some significant problems and limitations.

[0003] First of all, the existing waterproof bottom shell processing tooling usually adopts a relatively fixed structural design. This fixed structure is not flexible enough when it is necessary to perform milling grooves at different positions inside the bottom shell. The operator must frequently manually adjust the position of the bottom shell to adapt to the needs of different processing positions. This manual adjustment is not only time-consuming and labor-intensive, but also increases the workload of the operator. In a large-scale production environment, this inefficient operation method will significantly extend the production cycle and affect the overall production progress and cost control. More importantly, the positioning error that may be introduced during the manual adjustment process will directly affect the accuracy of the milling groove, thereby affecting the quality and function of the waterproof bottom shell.

[0004] Secondly, the processing of the waterproof bottom shell usually involves milling an inner groove on the inside of the bottom shell. Depending on different process requirements and processing locations, milling cutters of different specifications and types may need to be used. However, the tooling equipment in the existing technology shows obvious deficiencies in this regard. The equipment usually lacks a flexible tool changing mechanism, resulting in the operator having to stop the entire processing process when the milling cutter needs to be replaced and manually perform tedious milling cutter operations. This not only greatly prolongs the processing time, but also increases the complexity of the operation. Frequent tedious tool changing operations may also introduce additional errors, affecting the processing accuracy.

[0005] In order to solve the above problems, some equipment manufacturers have tried to adopt devices that can achieve quick tool change. These devices are designed to improve tool change efficiency and reduce processing interruption time. However, these quick tool change devices often have design defects. Their structure is relatively simple and they show insufficient stability in actual use. Specifically, after completing the tool change operation, these devices do not have an ideal fixing effect on the cutter disc. Under the action of high-speed rotation and cutting force, the fixing device is prone to vibration and impact, resulting in loose structure, and in severe cases, it may even fall off. This instability directly affects the working position of the milling cutter and causes deviations in processing accuracy. In the processing of waterproof bottom shells, precision deviations may cause the inner groove size to not meet the requirements, affecting the waterproof performance and overall quality of the final product.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the present invention provides a waterproof bottom shell processing tool with the following features:

[0019] Beneficial effects:

[0020] 1. The design of the processing device solves the problem of manual adjustment of the bottom shell position in the existing technology. By arranging the drive assembly, mounting frame, cutter head and milling cutter on the fixed frame and introducing a motor-driven screw system, the position of the bottom shell and drive assembly can be automatically adjusted.

The combination of horizontal and vertical movement enables the device to flexibly respond to the complex processing requirements inside the waterproof bottom shell and achieve all-round precise positioning. The setting of the slide rod further enhances the stability and accuracy of the movement process, ensuring the processing quality.

[0021] 2. The innovative design of the splicing device overcomes the defect of difficulty in replacing milling cutters in the existing technology. By introducing components such as splicing sleeves, adapter sleeves, movable plates, and splicing rods, the device realizes fast and convenient replacement of milling cutters. The design of the movable groove and adapter groove enables the movable plate to rotate flexibly, which is convenient for disassembly and installation of the splicing sleeve. This diversified splicing mechanism can not only quickly replace milling cutters of different specifications to adapt to different process requirements, but also greatly reduce tool change time while ensuring processing accuracy, thereby shortening downtime and improving overall processing efficiency.

[0022] 3. The design of the limiting mechanism solves the problem of poor stability of the rapid tool changing device in the existing technology. By introducing components such as a limiting sleeve, a limiting plate, a limiting rod, a fixed block, an arc groove, a circular groove, a movable block and a spring, the mechanism realizes the precise positioning and firm locking of the tool disc after tool change. The ingenious coordination of the limiting sleeve with the arc groove and the circular groove, combined with the dual protection of the limiting rod and the limiting plate, greatly improves the stability of the device. The setting of the push spring ensures the reliability and flexibility of the limiting process. This multiple locking mechanism effectively prevents the risk of structural loosening or falling off caused by vibration and impact under high-speed processing conditions, and ensures stability and accuracy during the processing.
