Description

Technical Field

[0001] This utility model relates to the field of impeller machining technology, and in particular to a positioning fixture for impeller machining. Background Technology

[0002] Diving originally referred to activities such as underwater exploration, salvage, repair, and underwater engineering, involving entering the water below the surface with or without specialized tools. However, with societal development, diving has gradually evolved into an activity primarily focused on underwater activities. During diving, a large amount of diving equipment is typically used, such as wetsuits and oxygen tanks. Among these, the diving propulsion device is one of the most common pieces of equipment, mainly used to assist divers in moving underwater. The most important component of this equipment is the impeller, which propels the diving device forward through its rotation.

[0003] When producing impellers, blades need to be welded to the impeller. However, the existing welding equipment is not perfect in the impeller positioning process. When blades in different positions need to be welded, the entire impeller needs to be disassembled and reinstalled, which greatly reduces work efficiency.

[0004] Therefore, a positioning fixture for impeller machining is proposed. Utility Model Content

[0005] To address the issue of needing to disassemble and reinstall the entire impeller when welding blades at different locations, this invention provides a positioning fixture for impeller processing.

[0006] This utility model provides a positioning fixture for impeller machining, which adopts the following technical solution:

[0007] A positioning fixture for impeller machining includes a worktable, the lower surface of which is provided with legs, and the upper surface of which is provided with two guide rails;

[0008] A mounting plate is provided on one side of the lower part of the workbench. An opener / closer is provided on one side of the mounting plate. A self-locking slider is slidably provided on the surface of the guide rail. A mounting seat is provided on the upper surface of the self-locking slider. A pressing mechanism is provided on the upper surface of the mounting seat.

[0009] By adopting the above technical solution, the guide rail can be adjusted laterally on the mounting base. The opening and closing device can control the guide rail. After the mounting base is adjusted, the opening and closing device is controlled to close, so that the self-locking slider cannot slide on the surface of the guide rail. The pressing mechanism can press and clamp the impeller to avoid the impeller from shifting during processing.

[0010] Optionally, the opener / closer is connected to the guide rail.

[0011] By adopting the above technical solution, the movement of the self-locking slider can be effectively controlled, preventing the self-locking slider from sliding randomly on the guide rail surface during processing.

[0012] Optionally, the upper surface of the mounting base is concave, and a rotating groove is formed on the inner side of the mounting base.

[0013] By adopting the above technical solution, the impeller can be effectively rotated. When the impeller is being processed, the rotating groove enables the impeller to rotate, thereby enabling processing of different positions and directions of the impeller, avoiding the need for single-mode processing, and also avoiding the need to disassemble the impeller again.

[0014] Optionally, a placement cylinder is provided at the concave surface of the upper surface of the mounting base.

[0015] By adopting the above technical solution, the inner circle of the impeller can be embedded into the inside of the placement cylinder. The placement cylinder can achieve the positioning effect of the inner circle of the impeller, thereby avoiding the phenomenon of the inner circle of the blades lifting up when the blades of the impeller are processed.

[0016] Optionally, the outer annular surface of the placement cylinder is embedded inside the rotating groove.

[0017] By adopting the above technical solution, the impeller can be effectively rotated. The rotation of the impeller is achieved by rotating the placement cylinder, thereby enabling processing at different positions of the impeller.

[0018] Optionally, the pressing mechanism includes:

[0019] Mounting plate two is disposed on the upper surface of the mounting base;

[0020] A pressure plate is located on one side of the pressing and holding mechanism;

[0021] The pressure block is located below one side of the pressure plate;

[0022] The grip is located on the other side of the pressing mechanism;

[0023] The connecting shaft connects the pressure plate to the handle.

[0024] By adopting the above technical solution, the impeller blades can be effectively pressed and held. When processing a certain blade, all blades can be pressed and held, avoiding the phenomenon of blades lifting up during processing.

[0025] Optionally, three pressing mechanisms are provided, with the three pressing mechanisms surrounding the annular edge of the upper surface of the placement cylinder.

[0026] By adopting the above technical solution, it is possible to press and hold blades in different positions and orientations, thus avoiding the phenomenon of blades tilting or shifting in different positions or orientations during processing.

[0027] Optionally, the placement tube is a retractable structure.

[0028] By adopting the above technical solution, the inner circle of the impeller can be effectively clamped, further preventing the impeller from shifting.

[0029] In summary, this utility model has the following beneficial effects:

[0030] This invention utilizes a rotating groove and a placement cylinder. The placement cylinder is a telescopic structure, with its outer annular surface embedded inside the rotating groove. By placing the inner circle of the impeller inside the placement cylinder, the impeller is positioned, preventing it from shifting during blade processing. Furthermore, when other blades of the impeller need to be processed, the placement cylinder can be rotated directly to achieve impeller rotation, avoiding the need to disassemble the entire impeller for processing other blades.

[0038] The following description, in conjunction with the embodiments of this utility model, includes appendices. Figure 1-5The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] Please refer to Figure 1-5 A positioning fixture for impeller machining, wherein the lower surface of the worktable 1 is provided with a support leg 101 and the upper surface of the worktable 1 is provided with two guide rails 2;

[0040] A mounting plate 102 is provided on one side of the lower part of the workbench 1. An opener 103 is provided on one side of the mounting plate 102. A self-locking slider 201 is slidably provided on the surface of the guide rail 2. A mounting seat 3 is provided on the upper surface of the self-locking slider 201. A pressing mechanism 4 is provided on the upper surface of the mounting seat 3.

[0041] By keeping the opener 103 in the open / closed state, the self-locking slider 201 can move laterally on the surface of the guide rail 2, thereby driving the mounting base 3 to move laterally. When it moves to the designated position, the opener 103 is then closed by control, thereby locking the automatic slider 201 to the surface of the guide rail 2, thus preventing the self-locking slider 201 from moving during the processing.

[0042] Secondly, during processing, the blades of the impeller are pressed by the pressing mechanism 4, which effectively prevents the blades from lifting up during the processing of the impeller. At the same time, when processing the blades at the impeller, all the blades are pressed to prevent the other blades from shifting due to the force generated during the operation.

[0043] Reference Figure 2 The opener / closer 103 is connected to the guide rail 2;

[0044] When the position of the mounting plate 3 needs to be adjusted, the opening and closing device 103 is controlled to open it, and then the mounting plate 3 is moved so that it slides on the surface of the guide rail 2 via the self-locking slider 201, thus achieving the effect of lateral movement of the mounting plate 3. When it is moved to the designated position, the opening and closing device 103 is controlled to close it, so that the self-locking slider 201 is fixed on the surface of the guide rail 2, thereby preventing the self-locking slider 201 from moving on the surface of the guide rail 2 during processing.

[0045] Reference Figure 3 The upper surface of the mounting base 3 is concave, and a rotating groove 301 is formed on the inner side of the mounting base 3.

[0046] The rotating groove 301 effectively achieves the rotation of the impeller, enabling the processing of blades at different positions on the impeller and avoiding the need to disassemble and reinstall the impeller.

[0047] Reference Figure 1 The upper surface of the mounting base 3 is provided with a placement cylinder 5;

[0048] The outer annular surface of the placement cylinder 5 is embedded inside the rotating groove 301;

[0049] By placing the inner circle of the impeller inside the placement cylinder 5, the impeller is positioned, preventing the impeller from shifting during the processing of the impeller blades. At the same time, when other blades of the impeller need to be processed, the placement cylinder 5 can be rotated directly to achieve the rotation of the impeller, avoiding the need to disassemble the entire impeller to process other blades.

[0050] Reference Figure 5 The pressure holding mechanism 4 includes:

[0051] Mounting plate 2 401 is disposed on the upper surface of mounting base 3;

[0052] Pressure plate 402 is disposed on one side of pressure holding mechanism 4;

[0053] Pressure block 403 is disposed below one side of pressure plate 402;

[0054] The grip 404 is located on the other side of the pressing mechanism 4;

[0055] Connecting shaft 405 connects pressure plate 402 to handle 404;

[0056] There are three pressing mechanisms 4, which surround the edge of the upper surface ring of the placement cylinder 5;

[0057] After the inner circle of the impeller is placed inside the placement cylinder 5, press the handle 404 to drive the pressure plate 402 to work. The working of the pressure plate 402 drives the pressure block 403 to press down, thereby pressing the blades of the impeller to prevent other blades from lifting or shifting when processing the blades of the impeller.

[0058] Secondly, after processing a certain blade, the clamping of the blade can be released, and the placement cylinder 5 can be rotated to drive the impeller to rotate. When it rotates to the blade that needs to be processed, the blade is clamped by the clamping mechanism 4.

[0059] Reference Figure 1 The placement cylinder 5 is a retractable structure;

[0060] The retractable placement cylinder 5 can effectively place impeller inner circles of different diameters and clamp the inner circle of the impeller, preventing the inner circle of the impeller from shifting during the processing of the impeller blades.

[0061] The implementation principle of this utility model is as follows: First, the impeller to be processed is placed inside the placement cylinder 5. Then, the blades of the impeller are pressed by the pressing mechanism 4, and the blades are processed. After a blade is processed, the pressing mechanism 4 is released from pressing the blade. Then, the placement cylinder 5 is rotated so that the placement cylinder 5 rotates inside the rotating groove 301, thereby driving the impeller to rotate. When it rotates to the designated position, the pressing mechanism 4 is used to press the blades of the impeller again, and the blades are processed.

[0062] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
