Description

Technical Field

[0001] This utility model relates to the field of LNG cylinder perforation technology, and in particular to a perforation device for sealing the end cap of a vehicle-mounted LNG cylinder. Background Technology

[0002] LNG cylinders are a key component of liquefied natural gas vehicles (LNGVs), primarily used for storing and supplying fuel. They are typically horizontally designed with a high-vacuum, multi-layered insulated structure.

[0003] Vehicle-mounted LNG cylinders are typically equipped with overfill protection devices, which consist of an overfill protection cylinder and an overfill protection end cap, forming an independent chamber. A small hole is located at the bottom of the overfill protection cylinder. Its function is to ensure that when the inner chamber is initially filled with liquid, the amount of liquid flowing into the gas tank is very small due to the small hole diameter, thus maintaining a certain safe gas phase space.

[0004] However, in practical applications, due to the diverse needs of customers, the drilling location is not limited to the central part of the bottom of the gas cylinder. This necessitates multiple adjustments to the position of the gas cylinder bottom during drilling to ensure accurate hole placement. These frequent adjustments complicate and cumbersome the process, leading to an increase in overall working time.

[0005] Therefore, this application provides an opening device for the sealing head of a vehicle-mounted LNG cylinder to meet the requirements. Utility Model Content

[0039] 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.

[0040] like Figure 1 - Figure 2 As shown, this utility model provides a technical solution: an opening device for sealing the end cap of a vehicle-mounted LNG cylinder, comprising:

[0041] The workbench 1 and the workpiece 7 are connected together. A punching machine 2 for punching holes is fixedly connected to the top of the workbench 1.

[0042] The workbench 1 is the foundation of the entire device, used to support and fix the workpiece 7 and other components to ensure accuracy and safety during the processing. The punching machine 2 is responsible for performing precise punching operations on the gas cylinder end caps. It is driven by a motor and can provide sufficient torque and speed to penetrate the metal end caps. The workpiece 7 refers to the LNG gas cylinder end caps that need to be punched. These end caps are usually made of high-strength metal materials to withstand high-pressure gas.

[0043] like Figure 3 - Figure 4 As shown, drive assembly 3 includes a motor 31 fixedly connected to both sides of the top of the worktable 1. The drive end of the motor 31 is fixedly connected to a support column 35. The top of the support column 35 is fixedly connected to a lead screw 32. The outer side of the lead screw 32 is threadedly connected to a drive block 33. The outer side of the lead screw 32 near the worktable 1 is threadedly connected to a positioning connection block 34. The top of the support column 35 contacts the bottom of the positioning connection block 34.

[0044] Motor 31 is the power source of drive assembly 3 and is fixedly connected to both sides of the top of worktable 1. Support column 35 provides a stable support point. The rotational motion of lead screw 32 is converted into linear motion by the drive of motor 31, thereby achieving precise positioning of workpiece 7. Drive block 33 moves along the axial direction of lead screw 32 as lead screw 32 rotates. Positioning connecting block 34 acts as a limiter for bottom clamping plate 42. The top of support column 35 contacts the bottom of positioning connecting block 34 to ensure that positioning connecting block 34 can avoid downward movement and maintain a stable support point when it is stable.

[0045] like Figure 1 , Figure 3 and Figure 4As shown, the positioning component 4 includes a top clamping plate 41 that engages with the top of the workpiece 7, a bottom clamping plate 42 at the bottom of the workpiece 7, an outer side of the driving block 33 that is rotatably connected to the top clamping plate 41, and an outer side of the positioning connecting block 34 that is fixedly connected to the bottom clamping plate 42.

[0046] The top clamping plate 41 engages with the top of the workpiece 7. This design allows the workpiece 7 to remain stable during the drilling process, ensuring the accuracy of the drilling position. The bottom end of the top clamping plate 41 is provided with a protruding part that matches the shape of the top of the workpiece 7 to achieve a firm engagement. The bottom clamping plate 42 is located at the bottom of the workpiece 7 and works in conjunction with the top clamping plate 41 to provide fixation for the workpiece 7 in both the upper and lower directions. The top end of the bottom clamping plate 42 is provided with a recessed part that matches the shape of the bottom of the workpiece 7 to achieve a firm engagement. The outer side of the drive block 33 is rotatably connected to the top clamping plate 41, so that the drive block 33 has an angle adjustment effect when it is adjusted up and down. When one of the motors 31 rotates, it can drive the workpiece 7 to achieve angle adjustment. The positioning connecting block 34 is fixedly connected to the bottom clamping plate 42 and works in conjunction with the drive block 33 to achieve precise positioning of the workpiece 7.

[0047] like Figure 4 As shown, the pressure support assembly 5 includes a damping column 51 fixedly connected to the top of the bottom plate 42. The top of the damping column 51 is in contact with the bottom of the top plate 41. A spring 52 is sleeved on the outside of the damping column 51. One end of the spring 52 is fixedly connected to the bottom plate 42, and the other end of the spring 52 is fixedly connected to the top of the damping column 51.

[0048] The damping column 51 is a key component in the pressure support assembly 5. It is fixedly connected to the top of the bottom clamping plate 42. The design of the damping column 51 needs to take into account its load-bearing capacity and stiffness to support the top clamping plate 41. When used in conjunction with the bottom clamping plate 42, it can fix the workpiece 7. The function of the spring 52 is to provide elastic support during the processing, allowing the workpiece 7 to move within a certain range.

[0049] like Figure 3 As shown, the rotating assembly 6 includes a second motor 61 fixedly connected to the worktable 1, and a support column 62 fixedly connected to the drive end of the second motor 61. The top end of the support column 62 contacts the bottom end of the workpiece 7.

[0050] Motor 61 is the power source for the rotating assembly 6, and support column 62 is an intermediary component connecting motor 61 and workpiece 7, with its top end contacting the bottom end of workpiece 7. This ensures that workpiece 7 can be stably supported and rotated during the rotation of motor 61.

[0051] Working principle: such as Figure 1-4 As shown, the workpiece 7 is first placed on the bottom clamping plate 42, and then the two motors 31 are started. The motors 31 drive the lead screw 32 to rotate through the support column 35. Then, the drive block 33 on the lead screw 32 will drive the top clamping plate 41 to move to the bottom until it engages with the top of the workpiece 7. At this time, the top of the damping column 51 will be in contact with the top clamping plate 41, which will prevent the drive block 33 from drooping due to excessive rotation, thus ensuring the stability of clamping the workpiece 7. Then, when angle adjustment is required, one of the motors 31 is started. When motor 1 31 drives the lead screw 32 and drives the drive block 33 to move, since the other end of the drive block 33 is fixed, the drive block 33 at this end will move up and down under the drive of motor 1 31. At this time, the drive block 33 at the other end will squeeze the spring 52 to ensure that it will not jam. When it is necessary to rotate the workpiece 7, the workpiece 7 is locked by the top clamping plate 41, and then motor 2 61 is started. Under the action of gravity, the bottom end of the workpiece 7 is fixed on the support column 62 and rotates.

[0052] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
