Description

Technical Field

[0001] The present invention belongs to the field of manufacturing and processing of fiber composite products, and particularly relates to a finishing device and processing method for a rotary body lug. Background Art

[0002] Fiber composite gas cylinders are increasingly used in various industries due to their excellent characteristics of light weight, high strength, and corrosion resistance. With the development of fields such as rail transit, new energy, and automobiles, in order to improve energy storage and achieve the best energy efficiency, the application demand for storing compressed gas is increasing. Fiber composite gas cylinders often need to be assembled and fixed to the equipment they carry to ensure the safety and stable performance of the gas cylinders during use. Especially for gas cylinders with high-pressure performance requirements or equipment with limited installation space, it is more necessary to ensure the accuracy of the gas cylinder assembly.

[0003] Whether it is a cylindrical, spherical, or annular gas cylinder, they all have a rotary body structure. In order to ensure the continuity of the fiber and the high performance and safety of the gas cylinder, an integrated molding design of continuous winding and embedded metal lugs is currently adopted. However, during the winding molding process and the curing process of the embedded metal lugs, the installation position will be affected by the winding tension and curing stress and undergo micro-displacements, which will affect the assembly accuracy and even make it impossible to assemble. This poses a design requirement for how to achieve and ensure the accuracy of the assembly interface of gas cylinders with high-precision assembly requirements without causing damage to the interface between the lugs and the gas cylinders.

Specific implementation mode

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. It should be noted that, without conflict, the embodiments and features in the embodiments of the present invention can be combined with each other. The described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0030] See Figure 1-7 In this embodiment, a rotary body lug finishing device includes an upper processing positioning frame 1, a lower fixed protective frame 2 and a front joint gas nozzle hole 5. The upper processing positioning frame 1 and the lower fixed protective frame 2 are connected at the lug 3. The gas cylinder 3 is located in the cavity formed by the upper processing positioning frame 1 and the lower fixed protective frame 2. The upper processing positioning frame 1 abuts against the front joint gas nozzle hole 5 of the gas cylinder tooling, and the lower fixed protective frame 2 is used to protect the rear head 11 of the gas cylinder 3.

[0031] On the upper processing positioning frame 1, there are designed a positioning shaft 19, a rib plate 20, an ear piece positioning surface 21, an ear piece positioning and processing hole 22, a lower connection hole 25, and a positioning scribed line 26. The rib plate 20 is trapezoidal, and the positioning shaft 19 runs horizontally through the top. The cooperation between the positioning shaft 19 and the front joint air nozzle hole 5 ensures the axial consistency between the rotary body ear piece finishing device and the gas cylinder 3. The middle scribed line on the gas cylinder ear piece 4 and the scribed line 26 on the lower fixed protective frame 2 ensure the circumferential position consistency between the gas cylinder 3 and the rotary body ear piece finishing device. The length of the rib plate 20 is designed according to the installation position of the ear piece on the gas cylinder. While meeting the ear piece installation dimensions, the hollow design is conducive to observing the state of the gas cylinder and performing machining operations. On both sides of the bottom of the rib plate 20, there are installed ear piece positioning surfaces 21, and on the ear piece positioning surfaces 21, there are provided ear piece positioning and processing holes 22 and lower connection holes 25.

[0032] On the lower fixed protective frame 2, there are designed a bottom support plate 12, a base 13, a rear head protective plate 14, a rear joint placement groove 15, a support block 16, an ear piece processing protective hole 17, a support rib 18, and an upper connection hole 24. At one end of the base 13, two support ribs 18 are vertically installed, and at the other end, a support block 16 is installed. On each support rib 18, a bottom support plate 12 is vertically installed. The base 13 is provided with a concave arc surface, and on the concave arc surface, there is provided a rear head protective plate 14. The rear head protective plate 14 cooperates with the rear head 11 of the gas cylinder 3. The placement groove 15 designed on the rear head protective plate 14 can place the rear joint 6 on the lower fixed protective frame 2 in a non-contact manner, and during the process of moving and processing the gas cylinder, it will not cause damage to the externally exposed metal rear joint 6. The rear head protective plate 14 is a hard rubber pad, which will not cause damage to the gas cylinder when moving the gas cylinder and can buffer and dampen vibration during machining the gas cylinder.

[0033] The length of the support rib 18 is designed according to the installation position of the ear piece on the gas cylinder. While meeting the ear piece installation dimensions, it supports and protects the gas cylinder, bears the machining force, and avoids damage between the metal parts and the composite material interface during the machining process. On the bottom support plate 12, there are provided an ear piece processing protective hole 17, an upper connection hole 24, and a positioning scribed line 26. The ear piece protective hole 17 is larger than the ear piece positioning and processing hole 22 on the upper processing positioning frame 1, and it will not affect the operation and movement of the machining tool during machining.

[0034] Adjust the positions of the ear piece positioning and processing hole 22 on the upper processing positioning frame 1, the gas cylinder 3, the middle scribed line on the gas cylinder ear piece 4, and the scribed line 26 on the lower fixed protective frame 2 to be consistent. Fix and connect the upper processing positioning frame 1, the gas cylinder 3, and the lower fixed protective frame 2 through the connecting bolt 8 and the connecting nut 9 to ensure the axial and circumferential position consistency between the gas cylinder and the rotary body ear piece finishing device. Machine process the ear piece installation hole 23 through the ear piece positioning and processing hole 22 to achieve the finish machining of the ear piece of the gas cylinder 3.

[0035] The method for finish machining the earpiece of the rotary body specifically includes the following steps:

[0036] (1) Place the support block 16 of the lower fixed protective frame 2 on the operating platform, place the rear head 11 of the gas cylinder 3 on the base 13 of the lower fixed protective frame 2, so that the exposed metal part of the rear joint 6 is placed in the rear joint placement groove 15 of the lower fixed protective frame 2. The designed placement groove 15 on the rear head protective plate 14 can place the rear joint 6 on the lower fixed protective frame 2 in a non-contact manner, and will not cause damage to the externally exposed metal rear joint 6 during the process of moving and machining the gas cylinder. The rear head protective plate 14 is a hard rubber pad, which will not cause damage to the gas cylinder when moving the gas cylinder and can buffer and absorb shock during machining the gas cylinder. Place the composite rear head 11 on the rear head protective plate 14 of the lower fixed protective frame 2, place the earpiece 4 of the gas cylinder 3 on the bottom support plate 12, and the length of the support rib 18 is designed according to the installation position of the earpiece on the gas cylinder. While meeting the earpiece installation dimensions, it supports and protects the gas cylinder, bears the machining force, and avoids damage between the metal parts and the composite material interface during the machining process. Adjust the position of the gas cylinder 3 so that the earpiece 4 of the gas cylinder corresponds to the earpiece machining protection hole 17 of the lower fixed protective frame 2. The earpiece protection hole 17 is larger than the earpiece positioning machining hole 22 on the upper machining positioning frame 1, and will not affect the operation and movement of the machining tools during machining.

[0037] (2) Insert the positioning shaft 19 of the upper machining positioning frame 1 into the front joint nozzle hole 5 of the front joint 7, place the earpiece positioning surface 21 on the earpiece 4, and the length of the rib plate 20 is designed according to the installation position of the earpiece on the gas cylinder. The cooperation between the positioning shaft 19 and the front joint nozzle hole 5 ensures the axial consistency of the rotary body earpiece finish machining device and the gas cylinder. While the rib plate 20 meets the earpiece installation dimensions, the hollow design is conducive to observing the state of the gas cylinder and performing machining operations. Adjust the position of the upper machining positioning frame 1 so that the earpiece positioning machining hole 22 on the upper machining positioning frame 1 corresponds to the earpiece 4 of the gas cylinder, and make the connection hole 25 of the upper machining positioning frame 1 correspond to the connection hole 24 of the lower fixed protective frame 2. Insert the connection bolt 8 through the connection hole 25 of the upper machining positioning frame 1 into the connection hole 24 of the lower fixed protective frame 2, adjust the position of the gas cylinder 3 so that the middle engraved line on the earpiece 4 of the gas cylinder is consistent with the engraved line 26 on the lower fixed protective frame 2. The middle engraved line on the earpiece 4 of the gas cylinder and the engraved line 26 on the lower fixed protective frame 2 ensure the circumferential position consistency of the gas cylinder and the rotary body earpiece finish machining device. Tighten the connection nut 9 to complete the fixed connection between the upper machining positioning frame 1 and the lower fixed protective frame 2.

[0038] (3) The machining of the cylinder lug 4 is carried out by positioning the machining hole 22 through the lug on the upper machining positioning frame 1. After the machining is completed, the connecting nut 9 is removed, the connecting bolt 8 is taken out, the upper machining positioning frame 1 is removed, and the cylinder 3 is taken out, completing the machining of the installation hole 23 of the cylinder lug, and realizing the finish machining of the cylinder lug of the cylinder 3.

[0039] The embodiments of the present invention disclosed above are only used to help illustrate the present invention. The embodiments do not describe all the details in detail, nor limit the invention to the specific embodiments described. According to the content of this specification, many modifications and variations can be made.
