[0002] A carburetor is a mechanical device that mixes gasoline and air in a specific ratio under the vacuum generated by the engine. As a precision mechanical device, the carburetor utilizes the kinetic energy of the intake airflow to atomize the gasoline. The carburetor automatically prepares and outputs the appropriate mixture concentration based on the engine's operating conditions. To ensure a relatively uniform mixture, the carburetor also atomizes the fuel for proper engine operation. Therefore, high precision is required in the positioning and installation of the carburetor components to guarantee effective fuel atomization through improved assembly quality.

Detailed Implementation

[0021] like Figures 1-8As shown, this embodiment provides a foam tube assembly device, including a frame 5 and an assembly mechanism 1. The assembly mechanism 1 includes a locking wire assembly seat 101, an assembly bit 102, and an assembly drive mechanism. The locking wire assembly seat 101 is disposed on the frame 5. An assembly hole 103 is provided in the middle of the locking wire assembly seat 101. The locking wire assembly seat 101 is provided with a first limiting slide 104 and a second limiting slide 105 communicating with the assembly hole 103. The first limiting slide 104 and the second limiting slide 105 are respectively located on the left and right sides of the locking wire assembly seat 101, and the first limiting slide 104 is located below the second limiting slide 105.

[0022] like Figure 2 and Figure 3 As shown, a first feeding slider 106 is slidably disposed within the first limiting slide 104. The first feeding slider 106 has a first feeding hole 107 adapted to the foam tube. The first feeding slider 106 is connected to a first driving mechanism 108. The first driving mechanism 108 is used to drive the first feeding slider 106 to slide along the first limiting slide 104 so that the first feeding hole 107 is coaxial with the assembly hole 103. The first driving mechanism 108 is usually a cylinder. The first driving mechanism 108 drives the first feeding slider 106 to move to one end of the first limiting slide 104, at which point feeding is performed, and the foam tube is inserted into the first feeding hole 107. The first driving mechanism 108 then drives the first feeding slider 106 to move to the other end of the first limiting slide 104, at which point the first feeding hole 107 is coaxial with the assembly hole 103.

[0023] A second feeding slider 109 is slidably disposed within the second limiting slide 105. The second feeding slider 109 has a second feeding hole 110 adapted to the main measuring orifice tube. The second feeding slider 109 is connected to a second driving mechanism 111. The second driving mechanism 111 is used to drive the second feeding slider 109 to slide along the second limiting slide 105 so that the second feeding hole 110 is coaxial with the assembly hole 103. The second driving mechanism 111 is usually a cylinder. The second driving mechanism 111 drives the second feeding slider 109 to move to both ends of the second limiting slide 105, at which point feeding is performed, and the main measuring orifice tube is inserted into the second feeding hole 110. The second driving mechanism 111 then drives the second feeding slider 109 to move to the other end of the second limiting slide 105, at which point the second feeding hole 110 is coaxial with the assembly hole 103.

[0024] The assembly drive mechanism is connected to the assembly bit 102. The assembly drive mechanism drives the assembly bit 102 to extend into the assembly hole 103 and contact the main measuring orifice tube, and drives the foam tube to rotate to achieve the assembly of the main measuring orifice tube and the foam tube. After the first feeding hole 107, the second feeding hole 110, and the assembly hole 103 are coaxial, the assembly drive mechanism drives the assembly bit 102 to move downwards and contact the main measuring orifice tube. Then, the assembly drive mechanism drives the assembly bit 102 to rotate, causing the assembly bit 102 to rotate with the main measuring orifice tube, thus achieving the threaded assembly of the main measuring orifice tube and the foam tube.

[0025] This invention enables the automatic assembly of the main measuring tube and the foam tube, which not only reduces the cost of manual labor but also avoids the problems of manual omissions and misassemblies, effectively improving the production efficiency of foam tube components. It can meet the needs of large-scale production and is well applicable to various types of production lines.

[0026] like Figure 3 As shown, in this embodiment, a material discharge slider 112 is provided at the bottom of the assembly hole 103. The material discharge slider 112 has a material discharge hole 113. A third driving mechanism 114 is connected to the material discharge slider 112. A first driving mechanism 108 is used to drive the material discharge slider 112 to slide radially along the assembly hole 103 so that the material discharge hole 113 is coaxial with the assembly hole 103. Preferably, the locking wire assembly seat 101 has a third limiting slide 115 communicating with the assembly hole 103. The material discharge slider 112 is slidably disposed within the third limiting slide 115. The third limiting slide 115 is perpendicularly connected to the assembly hole 103. When the material discharge slider 112 slides to one end of the third limiting slide 115, it blocks the assembly hole 103 to prevent the foam tube assembly from falling out. After the foam tube assembly is assembled, the material drop slider 112 slides a distance along the third limit slide 115, so that the material drop hole 113 is coaxial with the assembly hole 103, and the foam tube assembly falls from the assembly hole 103.

[0027] Below the assembly hole 103 is a material separating mechanism 4, which is used to separate qualified and unqualified products for feeding. Figure 8As shown, specifically, the material distribution mechanism 4 includes a material distribution slide plate 401 and a material distribution baffle 402. The material distribution slide plate 401 has a material distribution hole, and the material distribution baffle 402 is connected to a material distribution drive mechanism 403. The material distribution drive mechanism 403 is used to drive the material distribution baffle 402 to slide along the material distribution slide plate 401 to open or cover the material distribution hole, thereby separating qualified and unqualified products for material distribution. The material distribution slide plate 401 has a U-shaped structure, and the material distribution baffle 402 has an L-shaped structure. Both the material distribution slide plate 401 and the material distribution baffle 402 are inclined and rely on the gravity of the product for material distribution. The material distribution drive mechanism 403 typically uses a cylinder. When the material distribution drive mechanism 403 drives the material distribution baffle 402 to cover the material distribution hole, the qualified foam tube assembly falling from the assembly hole 103 slides along the material distribution baffle 402 and the material distribution slide plate 401 to achieve material feeding. When the material distribution drive mechanism 403 drives the material distribution baffle 402 to slide away from the material distribution hole, the unqualified foam tube assembly falling from the assembly hole 103 passes through the material distribution hole to be fed, which facilitates the collection of qualified and unqualified products.

[0028] like Figure 3 As shown, the assembly drive mechanism includes an assembly drive motor 116 and an assembly drive cylinder 117. The output shaft of the assembly drive motor 116 is slidably engaged with the assembly bit 102. The assembly drive motor 116 drives the assembly bit 102 to rotate, and the assembly drive cylinder 117 drives the assembly bit 102 to extend and retract. Under the action of the assembly drive cylinder 117, the assembly bit 102 can slide up and down along the output shaft of the assembly drive motor 116, allowing the assembly bit 102 to move closer to or further away from the main measuring orifice tube. Simultaneously, the output shaft of the assembly drive motor 116 can rotate the assembly bit 102, thus assembling the main measuring orifice tube and the foam tube.

[0029] like Figure 2 As shown, in this embodiment, the locking wire assembly base 101 is provided with a first feeding head 118 and a second feeding head 119. The first feeding head 118 is connected to a foam tube feeding mechanism 2, and the second feeding head 119 is connected to a main measuring orifice tube feeding mechanism 3. The locking wire assembly base 101 has two through holes, which are respectively connected to the first feeding head 118 and the second feeding head 119. The foam tube feeding mechanism 2 is used to supply foam tubes to the first feeding head 118, and the foam tubes enter the first feeding hole 107 after passing through the corresponding through holes. The main measuring orifice tube feeding mechanism 3 is used to supply main measuring orifice tubes to the second feeding head 119, and the main measuring orifice tubes enter the second feeding hole 110 after passing through the corresponding through holes.

[0030] like Figure 4As shown, specifically, the foam tube feeding mechanism 2 includes a foam tube vibrating plate 201 and a foam tube distributor 202. The output end of the foam tube vibrating plate 201 is connected to the foam tube distributor 202. The foam tube distributor 202 is used to output foam tubes one by one. A foam tube unloading pipe is provided between the foam tube distributor 202 and the first feeding head 118, thereby conveying the foam tubes to the first feeding hole 107.

[0031] The main orifice tube feeding mechanism 3 includes a feeding unit 31, a moving unit 32, a drilling unit 33, a cleaning unit 34, a flow detection unit 35, and a laser marking unit 36. The feeding unit 31 provides the main orifice tube; the moving unit 32 moves the main orifice tube; the drilling unit 33 drills the main orifice tube to form a main orifice; the cleaning unit 34 cleans the main orifice; the flow detection unit 35 detects whether the flow rate of the main orifice meets the standard; and the laser marking unit 36 ​​laser marks the outer wall of the main orifice tube.

The main orifice tube feeding mechanism 3 integrates drilling, cleaning, inspection and laser marking functions. It adopts automatic feeding and automatic production, reducing labor costs.

[0032] like Figure 5 As shown, the feeding unit 31 includes a main orifice tube vibratory plate 311, a main orifice tube distributor 312, and an ejection mechanism 313. The output end of the main orifice tube vibratory plate 311 is connected to the main orifice tube distributor 312. The main orifice tube distributor 312 is used to output the main orifice tubes one by one. The ejection mechanism 313 is used to eject the main orifice tubes. The ejection mechanism 313 includes an ejection cylinder and a push block. The push block is located at the output end of the main orifice tube distributor 312. The ejection cylinder drives the push block to eject the main orifice tube to the waiting point, and then the moving unit 32 moves the main orifice tube to the corresponding workstation.

[0033] like Figure 6 As shown, in one specific embodiment, the moving unit 32 includes a lifting seat 321, a lifting drive mechanism 322, a slide rail 323, a sliding drive mechanism 324, and a clamping mechanism 325. The output end of the lifting drive mechanism 322 is connected to the lifting seat 321. The slide rail 323 is slidably engaged with the lifting seat 321. The sliding drive mechanism 324 is used to drive the slide rail 323 to slide on the lifting seat 321. The slide rail 323 is provided with four clamping mechanisms 325 for clamping the main measuring orifice tube. The lifting drive mechanism 322 is a cylinder, which drives the lifting seat 321 to move up and down, so that the clamping mechanisms 325 carry the main measuring orifice tube to move up and down.

[0034] like Figure 7 As shown, the drilling unit 33 includes a pneumatic chuck 331, a lifting module 332, and a drill bit mechanism 333. The pneumatic chuck 331 is used to fix the main measuring hole tube, the lifting module 332 is connected to the drill bit mechanism 333, and the drill bit mechanism 333 is used to drill the main measuring hole on the main measuring hole tube.

[0035] The cleaning unit 34 includes an upper air blowing mechanism 341 and a lower collection mechanism 342. The upper air blowing mechanism 341 is used to blow air into the main metering orifice, and the lower collection mechanism 342 is used to collect debris blown out of the main metering orifice. The upper air blowing mechanism 341 includes an air blowing head connected to a cylinder. The cylinder drives the air blowing head to press against the main metering orifice of the main metering tube, and then blows air.

[0036] The assembly process of the foam tube assembly in this utility model includes the following steps: 1.
