Description

Technical Field

[0001] This utility model relates to the field of constant flow valve manufacturing technology, and in particular to a constant flow valve assembly frame. Background Technology

[0002] The constant flow valve is one of the core components of a lighter. Its main function is to precisely control the flow rate of combustible gas. To achieve efficient assembly of the constant flow valve, existing production lines typically use dedicated automated assembly equipment.

[0003] Considering the high requirements for operational safety during the assembly of constant flow valves, a closed cover is usually installed on the assembly machine. The cover can effectively isolate the external environment and prevent operators from accidentally touching the high-speed rotating mechanism.

[0004] To facilitate regular maintenance, troubleshooting, and necessary parts replacement of internal mechanisms, machine covers are usually equipped with access doors. However, traditional access door designs often only consider partial opening, making it difficult for operators to perform comprehensive and unobstructed maintenance. The frame structure of the machine cover itself, especially the top beams or supports, still forms a physical barrier after the access door is opened, preventing operators from extending their arms or tools into the area above the machine. This makes it very difficult to inspect, clean, calibrate, or replace the upper mechanisms.

[0005] Based on this, in order to improve the comprehensiveness of the inspection and maintenance of the mechanism above the machine, we propose a constant flow valve assembly frame. Summary of the Invention

[0006] The purpose of this utility model is to address the shortcomings of existing technologies, such as the difficulty for operators to perform comprehensive and unobstructed maintenance operations, and to propose a constant flow valve assembly frame.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Design a constant flow valve assembly rack, including:

[0009] The machine platform and the cover placed above the machine platform;

[0010] A number of positioning components are installed on the top of the machine, the machine cover and the number of positioning components are positioned and connected, and the positioning components and the machine cover are connected by a locking pin assembly;

[0011] The inner side of the hood is also equipped with several support components.

[0012] Furthermore, the positioning element has an L-shaped structure, and four positioning elements are matrix-distributed on the upper surface of the machine tool.

[0013] Furthermore, the locking pin assembly includes a insert rod that passes between the frame and the positioning element of the hood;

[0014] A locking rod is movably inserted inside the insertion rod, and at least one limiting bead is movably inserted outside the insertion rod. The outer side of the locking rod has an annular groove for accommodating the limiting bead. A spring is installed between the locking rod and the insertion rod.

[0015] Furthermore, the outer end of the insertion rod is formed with an outwardly expanding step, which stops on the outside of the frame, and the limiting bead stops on the inside of the positioning member.

[0016] Furthermore, the insert rod has a stepped section inside, the locking rod has a T-shaped cross-section, and the spring is placed between the stepped section and the end of the locking rod.

[0017] The outer side of the insertion rod is provided with a slot, and the outer side of the locking rod is provided with a guide that slides in the slot.

[0018] Furthermore, the support assembly includes a sleeve fixedly installed inside the frame of the hood, a support column slidably connected inside the sleeve, and a locking member for locking the support column on the outside of the sleeve.

[0019] Furthermore, a support platform is fixedly installed on the side of the machine base, and a clearance space is provided on the side of the machine cover, with the clearance space and the support platform being arranged opposite to each other.

[0020] Furthermore, at least one side of the hood is provided with an openable access door.

[0021] The present invention proposes a constant flow valve assembly frame, which has the following advantages: Based on the existing maintenance door, the frame structure of the present invention adopts a locking pin assembly and positioning component design to realize the positioning and disassembly connection of the entire machine cover. In this way, when it is necessary to perform comprehensive maintenance and repair on the assembly mechanism on the machine, the entire machine cover can be directly disassembled and separated, thus avoiding interference with the maintenance operation on the machine and greatly improving the convenience of equipment maintenance.

[0027] 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.

[0028] Reference Figure 1-4 As an embodiment of the present utility model, a constant flow valve assembly frame is disclosed. Specifically, the frame includes a machine base 1 and a machine cover 2 placed above the machine base 1. The machine cover 2 is used to protect the assembly mechanism on the machine base 1.

[0029] A plurality of positioning components 3 are installed on the top of the machine base 1. The machine cover 2 and the plurality of positioning components 3 are positioned and connected, and the positioning components 3 and the machine cover 2 are connected by a locking pin assembly 4.

[0030] The inner side of the casing 2 is also equipped with several support components 5.

[0031] In some embodiments, the positioning element 3 of this utility model has an L-shaped structure, and four positioning elements 3 are distributed in a matrix on the upper surface of the machine base 1. Of course, two adjacent positioning elements 3 are distributed in a symmetrical structure. Preferably, the positioning element 3 in this embodiment can be set as a profile, and the profile is fixed to the machine base 1 by fasteners such as bolts.

[0032] Furthermore, in this embodiment, the locking pin assembly 4 includes a rod 41 that passes through the frame 21 and the positioning member 3 of the cover 2, that is, through holes adapted to the rod 41 are provided on the end faces of the frame 21 and the positioning member 3.

[0033] A locking rod 42 is movably inserted into the inside of the insertion rod 41, and at least one limiting bead 43 is movably inserted into the outside of the insertion rod 41. That is, a ball hole adapted to the limiting bead 43 is opened on the end face of the insertion rod 41. Of course, the diameter of the ball hole should be smaller than the diameter of the limiting bead 43 to prevent the limiting bead 43 from falling out of the hole. The outer side of the locking rod 42 has an annular groove 44 to accommodate the limiting bead 43. A spring 45 is installed between the locking rod 42 and the insertion rod 41.

[0034] In other words, when actually assembling the machine cover 2, first align the bottom of the frame 21 of the machine cover 2 with the four positioning pieces 3 and insert them until they are completely placed above the machine base 1. After that, the insertion rod 41 can be inserted between the frame 21 and the positioning pieces 31. In this embodiment, the locking pin assembly 4 is also set to four.

[0035] During the insertion process, the locking rod 42 needs to be pressed to move inward. When the locking rod 42 retracts, its annular groove 44 will move to the lower side of the limiting bead 43. At this time, the limiting bead 43 has an inward space and can slide inward. In this state, the insertion rod 41 can be inserted.

[0036] Based on the above embodiments, in this embodiment, the outer end of the insertion rod 41 is formed with an outwardly expanding step 411, the outwardly expanding step 411 stops on the outside of the frame 21, and the limiting bead 43 stops on the inside of the positioning member 3.

[0037] Once the insertion rod 41 is inserted into the frame 21 and the positioning member 3, the pressure on the locking rod 42 can be released. Under the resistance of the spring 45, the locking rod 42 moves outward and resets. At the same time, its annular groove 44 disengages from the limiting bead 43 and protrudes outward from the outer plane of the locking rod 42 against the limiting bead 43. At this time, the outward expansion step 411 and the limiting bead 43 respectively abut against the sides of the frame 21 and the positioning member 3, thus completing the connection and locking of the cover 2 and the positioning member 3.

[0038] Conversely, when it is necessary to disassemble the machine cover 2 to carry out a comprehensive overhaul of the assembly mechanism on the machine base 1, press the locking rod 42 inward to control the limit bead 43 to retract inward. In this state, pull out the insertion rod 41 to complete the disassembly operation, and then lift the machine cover 2 upward to separate it.

[0039] It is worth noting that since components such as switches, touch screens, and warning lights will be installed on the top of the housing 2, in order to meet the separation requirements of the above-mentioned devices when the housing 2 is completely disassembled, the connecting wires of the above-mentioned devices can be designed to be detachable using a connector, such as an aviation plug, a plug-in terminal, or a wiring terminal. In this way, when the housing 2 is disassembled, it is only necessary to disconnect the wires of the corresponding devices, which will not affect the disassembly and separation operation of the housing 2.

[0040] Preferably, in this embodiment, the insert rod 41 is further formed with a stepped position 412 inside, the locking rod 42 has a T-shaped cross-section, and the spring 45 is placed between the stepped position 412 and the end of the locking rod 42.

[0041] The outer side of the insertion rod 41 is provided with a slot 413, and the outer side of the locking rod 42 is provided with a guide 421 that slides in the slot 413.

[0042] Preferably, the guide 421 described in this embodiment is a bolt. Specifically, the insertion rod 41 and the locking rod 42 described in this embodiment are detachable. When disassembling, only the guide 421 needs to be removed to take out the locking rod 42 and the spring 45 from the inside of the insertion rod 41. This design greatly improves the assembly convenience of the entire locking pin assembly 4.

[0043] In some embodiments, the support component 5 of this utility model includes a sleeve 51 fixedly installed inside the frame 21 of the machine cover 2, and a support column 52 slidably connected inside the sleeve 51. The support column 52 has a T-shaped structure, and a locking member 53 for locking the support column 52 is provided on the outside of the sleeve 51. Preferably, in this embodiment, four sleeves 51 and four support columns 52 can be adapted to be provided.

[0044] Of course, the locking component 53 described in this embodiment is also set as a bolt. The bolt is threadedly connected to the sleeve 51 and abuts against the support column 52. The purpose of using this support component 5 in this embodiment is to make it easier to place the machine cover 2 on the ground when it is disassembled. In this embodiment, the adjustable support column 52 is provided. When disassembling, the support column 52 can be pulled out from the inside of the sleeve 51 and then locked and fixed by the locking component 53. In this way, after the machine cover 2 is disassembled, it can be placed on the ground by the support column 52 to improve the convenience of its placement after disassembly.

[0045] It should be noted that in this embodiment, a support platform 11 is fixedly installed on the side of the machine base 1, and a clearance space 22 is provided on the side of the machine cover 2. The clearance space 22 and the support platform 11 are arranged opposite to each other. In this embodiment, the support platform 11 can be used to place components such as the feeding tray, and the clearance space 22 is used to provide installation space for external mechanisms to enter the interior of the machine cover 2.

[0046] Of course, in order to meet the needs of convenient routine maintenance, at least one side of the machine cover 2 in this embodiment is provided with an openable maintenance door 23. The maintenance door 23 can also be a glass door to avoid observing the working status inside the entire machine cover 2.

[0047] In summary, the frame structure of this utility model, based on the existing maintenance door 23, adopts the design of locking pin assembly 4 and positioning component 3 to realize the positioning and disassembly connection of the entire machine cover 2. Thus, when it is necessary to perform comprehensive maintenance and repair on the assembly mechanism on the machine base 1, the entire machine cover 2 can be directly disassembled and separated, thereby avoiding interference with the maintenance operation on the machine base 1 and greatly improving the convenience of equipment maintenance.

[0048] 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 disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
