Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-3 This utility model provides a technical solution to achieve this: a parts hoisting clamp for parts processing, characterized in that: it includes a lifting ring 1, a plurality of first shaft plates 2, a plurality of second shaft plates 3, a plurality of rotating shafts 4, and a clamping mechanism 5. The first shaft plates 2 are arranged opposite each other on the left and right and staggered front and back at the bottom of the lifting ring 1. The second shaft plates 3 are staggered below each first shaft plate 2. The rotating shafts 4 are arranged at the intersection of the lifting ring 1 and the first shaft plate 2 and the intersection of the first shaft plate 2 and the second shaft plate 3. The clamping mechanism 5 is arranged below the second shaft plate 3.
[0024] The core clamping mechanism 5 includes a clamping plate 51, a rotating ramp 52, a hinge slot 53, several hinges 54, a clamping plate 55, an anti-slip pad 56, several fixing blocks 57, several high-strength dampers 58, and a universal joint 59. The clamping plate 51 has an arc-shaped structure and is arranged in a staggered manner with each second shaft plate 3. The rotating ramp 52 is located at the front and rear ends of the bottom of each clamping plate 51. The hinge slot 53 is located at the bottom of each clamping plate 51 and between the rotating ramps 52 at the front and rear ends. The several hinges 55... 4 are arranged in an upper and lower structure inside the hinge slot 53. The clamping plate 55 is arranged on the hinge 54. The anti-slip pad 56 is arranged on the opposite side of each clamping plate 55. The fixing block 57 is evenly arranged at the front and rear ends of the clamping plate 51. One end of the strong damper 58 is arranged on the fixing block 57 and the other end extends towards the nearest clamping plate 55. The universal joint 59 is arranged at the front and rear ends of the side of each clamping plate 55 facing the nearest fixing block 57 and is connected to the nearest strong damper 58.
[0025] Specifically, each hinge 54 has a connecting block 541 on the end away from the other hinge 54, and the connecting block 541 is integrally formed with the clamping plate 51.
[0026] In detail, the clamping plate 55 has a clamping groove 551 inside, which has an arc-shaped structure, and anti-slip pads 56 are located on the left and right sides of each anti-slip pad 56.
[0027] The fixing block 57 has a right-angled trapezoidal structure. The fixing blocks 57 are distributed diagonally in an upper and lower structure, and each vertical surface of the fixing block 57 faces the direction of the fixing block 57. Each fixing block 57 is inclined towards the lower half of the clamping plate 55. The fixing block 57 and the clamping plate 51 are integrally formed.
[0028] This design incorporates a novel clamping mechanism 5. The clamping plate 55 can rotate via hinge 54, increasing the maximum circumference of the clamping slot 551, thus enabling the clamping of parts of various sizes. Furthermore, during clamping, the clamping force causes the clamping plate 55 to apply force to the high-strength damper 58, effectively clamping parts of different sizes without reducing the clamping strength. When the clamping plate 55 is flipped, the universal joint 59 ensures smooth rotation. This design effectively expands the applicability of the part lifting clamp and significantly improves the clamping effect.
[0029] Working principle: When hoisting cylindrical or cylindrical parts of different specifications, the suspended clamping plate 51 is manually opened and clamped onto the current part. If the current part is large, as it comes into contact with the surface of the part, the clamping plate 55 will be opened by a larger arc and rotated through the hinge 54. The rotation ramp 52 provides sufficient rotation space for the clamping plate 55. As rotation continues, it is opened to an angle suitable for the part under the current manual force. Then, the hoisting is controlled, and the upward pulling force straightens the first shaft plate 2 and the second shaft plate 3, which in turn drives the clamping plate 51 to clamp the part. Under the action of the strong damper 58 and the universal joint 59, the part is finally tightly clamped and lifted.
[0030] The components of this utility model are: 1-lifting ring; 2-several first shaft plates; 3-several second shaft plates; 4-several rotating shafts; 5-clamping mechanism; 51-clamping plate; 52-rotating ramp; 53-hinge groove; 54-several hinges; 541-connecting block; 55-clamping plate; 551-clamping groove; 56-anti-slip pad; 57-several fixing blocks; 58-several high-strength dampers; 59-universal shaft. These components are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is that existing parts lifting clamps for parts processing have significant limitations when clamping cylindrical or cylindrical objects. They can only clamp objects of fixed specifications and cannot clamp cylindrical or cylindrical objects of various specifications. This reduces production efficiency and the work efficiency of workers during periods of high production pace. This utility model effectively improves the applicability of parts lifting clamps and effectively improves the clamping effect.
