Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a spring mounting device for a tube assembly machine. Background Technology

[0002] The fuel filler pipe assembly of this technology includes a filler pipe body 100 and a filler pipe cap 200, which are important components of the automotive fuel system. The filler pipe cap is a component that covers the fuel filler neck of the vehicle, primarily serving to allow the fuel nozzle to enter, conceal the fuel tank filler neck (anti-theft), and for decorative purposes. During assembly of the fuel filler pipe assembly, the filler pipe cap pivot 300 and the torsion spring 400 need to be installed on the filler pipe body 100 and the filler pipe cap 200, respectively. Currently, existing technologies still rely on manual operation using tools such as vises, which is inefficient, especially since the torsion spring 400 is difficult to install. The torsion spring 400 requires rotation to apply torque before the filler pipe cap pivot 300 can be installed. However, there is currently no suitable assembly equipment available in the existing technology.

[0003] Therefore, there is an urgent need to propose a spring mounting device for a tube assembly machine that is simple in structure, easy to operate, and reliable. Utility Model Content

[0037] like Figures 1 to 13 As shown, this embodiment provides a nozzle assembly machine, which installs an oil port cover shaft 300 and a torsion spring 400 at the connection between the nozzle body 100 and the nozzle cover 200, and assembles them to obtain a nozzle assembly 10. Specifically, the spring mounting device of the nozzle assembly machine includes a lower worktable 1, an upper protective cover 2 and a worktable surface 4 disposed on the lower worktable 1, an industrial control computer 3 disposed on the upper protective cover 2, and a nozzle assembly clamping assembly 5 and a torsion spring mounting assembly 6 disposed on the worktable surface 4.

[0038] In this embodiment, the nozzle body 100 and nozzle cap 200 are reliably fixed vertically, horizontally, and laterally using the nozzle assembly clamping component 5. Specifically, the nozzle assembly clamping component 5 includes a clamping fixture mounting base 501 and a first column 512 mounted on the worktable 4, a front clamping support 502, a rear clamping support 507, and a side compression mechanism mounted on the clamping fixture mounting base 501, a first upper mounting plate 513 fixed on the first column 512, an upper compression mechanism mounted on the first upper mounting plate 513, and a rear compression mechanism mounted on the rear clamping support 507. The nozzle body 100 and nozzle cap 200 are placed on the front clamping support 502 and the rear clamping support 507 and are compressed by the side compression mechanism, the upper compression mechanism, and the rear compression mechanism.

[0039] Here, the side-clamping mechanism includes a first side-clamping mounting base 503 fixed to the clamping fixture mounting base 501, a first side-clamping cylinder 504 fixed to the first side-clamping mounting base 503, a first side-clamping linkage frame 505 connected to the first side-clamping cylinder 504, and a first side-clamping positioning post 506 fixed to the first side-clamping linkage frame 505 and clamping onto the nozzle cover 200. Additionally, the upper-clamping mechanism includes a first longitudinal cylinder 514 fixed to the first upper mounting plate 513 in the longitudinal direction, and a first upper clamping seat 515 disposed at the bottom of the first longitudinal cylinder 514. The first upper clamping seat 515 clamps onto the nozzle body 100. Finally, the rear extrusion mechanism includes a second cylinder mounting base 508 fixed on the rear clamping support 507, a second cylinder 509 disposed on the second cylinder mounting base 508, a second slider 510 disposed on the second cylinder 509, and a rear extrusion block 511 disposed on the second slider 510 and extruding onto the nozzle body 100. In this way, the nozzle body 100 and the nozzle cover 200 can be reliably fixed to facilitate the installation of the oil port cover shaft 300 and the torsion spring 400.

[0040] In this embodiment, the torsion spring 400 needs to be subjected to torque and installed on the port body 100 and port cover 200 so that it can be opened by the port cover 200 during refueling. Here, the torsion spring mounting assembly 6 includes a torsion spring rotation drive mechanism 62 fixed on the worktable surface 4, and a torsion spring locking mechanism 61 provided on the torsion spring rotation drive mechanism 62. The torsion spring rotation drive mechanism 62 is used to apply torque to the torsion spring 400 and press down the port cover shaft 300.

[0041] Here, the torsion spring rotation drive mechanism 62 includes several second mounting columns 6201 fixed on the worktable 4, a second mounting base 6202 fixed on the second mounting columns 6201, a first sliding module 6203 and a second slide rail 6204 fixed on the second mounting base 6202, a second slider 6205 slidably sleeved on the second slide rail 6204, a second sliding plate 6206 fixed on the second slider 6205 and connected to the first sliding module 6203, a second sliding module 6207 and a third slide rail 6208 fixed on the second sliding plate 6206, and a set... A third slide plate 6209 is mounted on the third slide rail 6208 and connected to the second sliding module 6207. A vertical mounting plate 6210 is mounted on the third slide plate 6209. A longitudinal sliding module 6211 is mounted on the vertical mounting plate 6210. A fourth slide plate 6212 is mounted on the longitudinal sliding module 6211. A motor 6213 and a rotating bearing support 6214 are fixed to the fourth slide plate 6212. A rotating connecting shaft passes through the rotating bearing support 6214 and is connected to the motor 6213. A torsion spring torsion head 6217 is located at the bottom of the rotating connecting shaft. The motor 6213 drives the torsion spring torsion head 6217 to rotate the torsion spring 400. Additionally, a first pressing seat 6215 and a second pressing seat 6216 are located at the bottom of the fourth slide plate 6212. When the torsion spring 400 rotates and applies torque, the second pressing seat 6216 presses against the nozzle body 100. When the oil port cover shaft 300 is inserted, the first pressing seat 6215 is used to press down and install the oil port cover shaft 300.

[0042] In this embodiment, after the torsion spring 400 is rotated and torque is applied, it needs to be locked, and then the oil port cover rotating shaft 300. Therefore, the torsion spring locking mechanism 61 includes a first mounting base 6101 disposed on the second mounting base 6202, a horizontal sliding assembly disposed on the first mounting base 6101 in the horizontal direction, a first return spring mounting base 6103 disposed at the rear end of the first mounting base 6101, a second return spring mounting base 6105 disposed on the horizontal sliding assembly, a return spring 6106 disposed between the first return spring mounting base 6103 and the second return spring mounting base 6105, a torsion spring pressing seat 6108 disposed at the front end of the horizontal sliding assembly and pressed against the rotated torsion spring 400, a locking fixing head 6111 disposed on the horizontal sliding assembly, a locking head pushing cylinder 6109 fixed in the longitudinal direction on the first mounting base 6101, a locking movable head 6110 connected to the locking head pushing cylinder 6109 and pressed against the locking fixing head 6111, and a pushing handle 6107 disposed on the horizontal sliding assembly. The horizontal sliding assembly includes several first slide rails 6102 fixed horizontally on the first mounting base 6101, and a first slide plate 6104 slidably sleeved on the first slide rails 6102; the second reset spring mounting base 6105, the push handle 6107 and the torsion spring compression base 6108 are disposed on the first slide plate 6104.

[0043] When the nozzle body 100 and nozzle cap 200 are fixed to the nozzle assembly clamping assembly 5, the torsion spring 400 is placed at the connection and installation point of the nozzle body 100 and nozzle cap 200. The motor 6213 drives the torsion spring torsion head 6217 to rotate, applying torque to the torsion spring 400. The push handle 6107 is manually pushed, causing the torsion spring compression seat 6108 to press against the torsion spring 400 after the torque is applied, preventing it from elastically returning to its original position. Then, the locking head push cylinder 6109 pushes the locking movable head 6110 to lock onto the rear end of the locking fixed head 6111. At this time, the return spring 6106 is in a stretched state. The longitudinal sliding module 6211 lifts the torsion spring torsion head 6217, allowing the oil port cap shaft 300 to be inserted into the connection position where the torsion spring 400 is located. The connection is then completed by pressing and installing it using the first compression seat 6215.

[0044] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any changes made based on the design principles of this utility model, or any non-creative changes made on this basis, shall fall within the scope of protection of this utility model.
