Description

Technical Field

[0001] The present invention relates to the field of engine component assembly equipment, and particularly to a quick-detachable locking and rotating device. Background Art

[0002] The urea injection device is an accessory of a diesel engine, and is composed of components such as a pot body, a high-pressure pump, and a pipeline. During the assembly process of the urea injection device of the engine, it is necessary to fix the pot body and then install each component on the pot body. Since the installation positions are distributed at various positions of the pot body, the pot body needs to be rotated during assembly to complete the installation of each component. The existing urea injection device assembly equipment fixes the support frame on a tray that can rotate 360° for assembly. However, when it is necessary to replace with different new types of urea injection devices for assembly, it is necessary to disassemble the existing support frame and replace it with a matching support frame. Since the sizes of different types of urea injection devices are different, the sizes of the support frames are also different, and the installation hole positions are different and cannot be quickly installed, resulting in high labor intensity for replacing the support frame during the assembly process of the urea injection device, poor adaptability, difficult disassembly, and low assembly efficiency.

[0020] The present invention will be further described in detail below in conjunction with specific embodiments. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0021] As Figures 1 to 7 shown, a quick-detachable locking and rotating device, characterized in that: it includes a rotating base 1, a positioning plate 2, a cover plate 3, a retaining ring 4 and a clamping block 5. The rotating base 1 is circular in shape, and a relief hole 6 is provided at the center of the rotating base 1 for making way for the rotating shaft 7 on the tray. The rotating base 1 is fixed on the body 15 of the tray. The positioning plate 2 is circular in shape, and a U-shaped groove 8 is provided at the front part of the positioning plate 2. A rotating shaft mounting position 9 is provided at the center of the positioning plate 2 for connecting the rotating shaft 7 on the tray, and the rotating shaft 7 drives the positioning plate 2 to rotate. The cover plate 3 is circular in shape and has a U-shaped opening 10 in the middle. The cover plate 3 is cooperatively connected with the positioning plate 2 to cover the U-shaped groove 8 to form a limiting cavity 11 for installing the clamping block 5. The middle part of the retaining ring 4 is hollow, and an opening is provided at the upper part thereof. The retaining ring 4 is installed outside the positioning plate 2. A number of threaded holes 12 are evenly provided on the retaining ring 4, and a positioning groove 13 is provided at the bottom of the threaded hole 12. A support threaded post 14 is installed on the positioning groove 13, and the retaining ring 4 is fixed on the body 15 of the tray by cooperating bolts with the threaded holes 12 and the support threaded post 14. The clamping block 5 is U-shaped, and a connecting column 16 is provided at the front part of the clamping block 5. A support frame mounting position 17 is provided on the connecting column 16 for connecting the support frame. An extension end 18 is provided at the upper part of the clamping block 5, and a bearing 19 is installed on the extension end. The clamping block 5 cooperates with the limiting cavity 11, and the bearing 19 cooperates with the inner side of the retaining ring 4.

[0022] Furthermore, the U-shaped openings 10 of the cover plate 3 and the U-shaped grooves 8 of the positioning plate 2 correspond to each other and the notch openings are all upward. The consistent notch openings facilitate the installation of the clamping block 5 in the limiting cavity 11. The size of the U-shaped opening 10 of the cover plate 3 is smaller than the size of the U-shaped groove 8 of the positioning plate 2, and chamfers 20 are provided on both sides of the U-shaped opening 10 of the cover plate 3.

[0023] The working principle of the present invention is as follows: The support frame for fixing the kettle body of the urea injection device is fixed on the connecting column 16. The clamping block 5 cooperates with the limiting cavity 11 to support the support frame. The rotating shaft 7 of the tray is connected to the positioning plate 2. When it is necessary to rotate the support frame, the rotating shaft 7 drives the positioning plate 2 to rotate and drives the clamping block 5 in the limiting cavity 11 to rotate, so as to realize the rotation of the support frame connected to the clamping block 5. During the rotation process, the bearing 19 on the clamping block 5 cooperates with the inner side of the retaining ring 4 to limit the clamping block 5, preventing the clamping block 5 from sliding out of the limiting cavity 11 during the rotation process. Each type of support frame is equipped with a clamping block 5. When it is necessary to change the type, the clamping block 5 can be loaded and unloaded in the limiting cavity 11, and the support frame can be quickly installed on the tray, realizing the quick loading and unloading of the support frame.
