Description

Technical Field

[0001] This utility model belongs to the field of machinery, and specifically relates to a special hoisting tool. Background Technology

[0002] The 24-position tool turret is specifically designed for CNC lathes. When machining crankshafts, the tool holder positions are arranged according to the machining sequence and tool life. The tool turret is typically replaced every 3 or 4 shifts. The entire tool turret weighs around 100 kg when fully loaded, and some larger sizes weigh even more. Therefore, overhead cranes are required to assist in changing or transporting the tool turret. During transport, it is difficult to maintain the balance of the tool turret using ordinary ropes or hoisting methods, which cannot guarantee that the cutting tools on the tool turret will not be damaged by impact or injure people, posing a significant safety hazard. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a dedicated hoisting tool.

[0004] The technical solution of this utility model is implemented as follows: A special lifting tool includes a cutter head, a central hole in the middle of the cutter head, and positioning pin positioning holes A and B on the same horizontal line on both sides of the central hole. A lifting plate is provided above the cutter head, and a lifting ring is provided above the lifting plate. A fixing plate is provided below the cutter head, and a fixing pin hole is provided in the middle of the fixing plate. Positioning pin holes are provided on the same horizontal line on both sides of the fixing pin hole. A connecting plate is provided below the fixing plate, and connecting holes are provided in the middle and at both ends of the connecting plate. A rotating shaft is provided in the positioning pin hole, and a positioning pin is provided at the upper end of the rotating shaft. The lower end of the rotating shaft passes through the knurled handle of the connecting plate and is connected. A fixing sleeve is provided on the outside of the rotating shaft, and a spring is provided between the lower end of the fixing sleeve and the knurled handle. Positioning pin grooves are provided on both positioning pin positioning holes A and B. A fixing pin shaft is provided in the fixing pin hole. The fixing pin shaft is connected and fixed to the connecting plate, the fixing plate, the cutter head, and the lifting plate.

[0005] Preferably, the positioning pin, under the action of the knurled handle and the spring, cooperates with the positioning pin grooves on the positioning pin positioning hole A and positioning pin positioning hole B to perform positioning and retraction.

[0006] Preferably, the fixing pin hole, the center hole, and the connecting hole in the middle of the connecting plate are located on the same vertical center line, and the two positioning pin holes are located on the same vertical center line as the positioning pin positioning hole A and positioning pin positioning hole B on the cutter head, respectively.

[0007] The beneficial effects of this utility model are: the lifting tool of this utility model is simple in design, easy to manufacture and easy to operate in practical applications, with a low failure rate. It can not only ensure that the cutter head blades are not damaged during transportation, but also reduce the labor intensity and operational risk of the operator. Furthermore, cutter head lifting tools of different specifications can be designed and manufactured. Attached Figure Description

Detailed Implementation

[0015] 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.

[0016] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] See attached document Figure 1A special lifting tool includes a cutter head 3, with a central hole 15 in the middle. Positioning pin holes A11 and B12 are respectively located on the same horizontal line on both sides of the central hole 15. A lifting plate 2 is located above the cutter head 3, and a lifting ring 1 is located above the lifting plate 2. A fixing plate 14 is located below the cutter head 3, with a fixing pin hole 13 in the middle. Positioning pin holes 16 are respectively located on the same horizontal line on both sides of the fixing pin hole 13. A connecting plate 8 is located below the fixing plate 14, with connecting holes in the middle and at both ends. The fixing pin hole 13, the connecting holes, and the central hole 15 of the cutter head 3 are located at the same vertical center. Online, the two positioning pin holes 16 are respectively located on the same vertical center line as the positioning pin positioning holes A11 and B12 on the cutter head 3. A rotating shaft 5 is provided in the positioning pin hole 16. The upper end of the rotating shaft 5 is provided with a positioning pin 4. The lower end of the rotating shaft 5 passes through the connecting plate 8 and is connected to the knurled handle 7. A fixing sleeve 10 is provided on the outside of the rotating shaft 5. A spring 6 is provided between the lower end of the fixing sleeve 10 and the knurled handle 7. Positioning pin grooves 17 are provided on both the positioning pin positioning holes A11 and B12. A fixing pin shaft 9 is provided in the fixing pin hole 13. The fixing pin shaft 9 is connected and fixed to the connecting plate 8, the fixing plate 14, the cutter head 3, and the hanging plate 2.

[0018] Specific usage method: In the early stage, the center of gravity of the cutter head in the full cutting state can be analyzed by 3D software. During the actual lifting, the positioning pin positioning holes A11 and B12 on the cutter head 3 are the lifting ports reserved in the design of the cutter head. Both are equipped with positioning pin grooves 17. When disassembling and operating the cutter head 3, the lifting plate 2 is suspended by the lifting rope through the lifting ring 1. The fixing pin shaft 9 is fixedly connected to the lifting plate 2, the cutter head 3, the fixing plate 14 and the connecting plate 8. Hold the knurled handle 7 with both hands and align the two rotating shafts 5 with the positioning pin grooves 17 of the positioning pin positioning holes A11 and B12 on the cutter head 3 respectively. Then, use the elastic deformation of the spring 6 to push the knurled handle 7 forward. After the positioning pin 4 passes through the cutter head 3, rotate the knurled handle 7 90°. At this time, the spring returns to its original position, so that the positioning pin 4 is stuck on the back of the cutter head 3, preventing the rotating shaft 5 from coming out of the cutter head body during the lifting process. Since the center of gravity of the cutterhead 3 and tooling had been calculated in advance, the cutterhead remained vertical during hoisting, and both hands only needed to grip the knurled handle 7. When it was necessary to remove the lifting equipment, simply turn the handle 7 with both hands to the positioning pin 4 and the lifting ports A and B, and then remove it to complete the entire hoisting process.

[0019] This lifting device is simple in design, easy to manufacture, and easy to operate in practical applications. It has a low failure rate, reduces the labor intensity of operators, and can also be designed and manufactured in different specifications of cutterhead lifting devices.

[0020] 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 of the present utility model based on the technical solution and the inventive concept of the present utility model are covered within the protection scope of the present utility model.
