Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and in particular to a positioning and cutting device and method for processing plastic fuel tanks. Background Technology

[0002] Plastic fuel tanks, especially multi-layered plastic fuel tanks for automobiles, are widely used in the modern automotive industry due to their advantages such as light weight, corrosion resistance, and high design flexibility. After blow molding, these fuel tanks require precise openings in their bodies to install components such as fuel pumps, floats, valves, and various sensors. These openings have strict requirements for positional accuracy, dimensional precision, and cut quality to ensure the correct installation of subsequent components and the sealing and safety of the entire fuel system.

[0003] Currently, the industry generally uses traditional manual methods to process the openings of plastic fuel tanks. Specifically, operators first use templates or experience to mark lines on the surface of the fuel tank for positioning, and then use handheld cutting tools (such as jigsaws, vibrating knives, or heat guns) to cut along the marked lines.

[0004] However, in the aforementioned existing technologies, human cutting errors are large, which can easily cause the opening position to deviate from the design benchmark. This not only affects the installation of subsequent components, but may even cause the entire fuel tank to be scrapped due to incorrect positioning, resulting in economic losses. Summary of the Invention

[0005] The purpose of this invention is to provide a positioning and cutting device and method for processing plastic fuel tanks, aiming to solve the technical problem in the prior art where large human errors easily lead to the opening position deviating from the design benchmark. This not only affects the installation of subsequent components, but may even cause the entire fuel tank to be scrapped due to incorrect positioning, resulting in economic losses.

[0006] To achieve the above objectives, the present invention employs a positioning and cutting device for processing plastic fuel tanks, comprising a worktable, a cutting assembly, a clamping assembly, and a receiving assembly. The cutting assembly includes a side column, a slider, a mounting bracket, a drive motor, a quick-release head, a shaped blade, a driving component, and auxiliary components. The cutting assembly, the clamping assembly, and the receiving assembly are respectively connected to the worktable. The side column is fixedly connected to the worktable and located above it. The slider is slidably connected to the side column and located on the inner side wall of the side column. The mounting bracket is fixedly connected to the slider and located on the outer side wall of the slider. The drive motor is detachably connected to the mounting bracket and located above it. The quick-release head is fixedly connected to the drive motor and located at its output end. The shaped blade is detachably connected to the quick-release head and located below it. The driving component is connected to the side column and the slider respectively. The auxiliary components are connected to the mounting bracket and the worktable respectively.

[0007] The cutting assembly further includes a slide and a locking bolt. The slide is detachably connected to the quick-release head and is located below the quick-release head. The slide is in contact with the shaped blade, and the locking bolt passes through the shaped blade and is threadedly connected to the slide.

[0008] The cutting assembly further includes a support frame and a buffer pad. The support frame is fixedly connected to the worktable and located above the worktable, and the buffer pad is fixedly connected to the support frame and located above the support frame.

[0009] The driving component includes a threaded rod and a stepper motor. The threaded rod is rotatably connected to the side column and is located on the inner side wall of the side column. The threaded rod is threadedly engaged with the slider. The stepper motor is detachably connected to the side column and is located above the side column. The output end of the stepper motor is fixedly connected to the threaded rod and is located above the threaded rod.

[0010] The auxiliary component includes a slide rod and a connecting ring. The slide rod is fixedly connected to the worktable and located above the worktable. The connecting ring is fixedly connected to the mounting bracket and located on one side of the mounting bracket. The connecting ring and the slide rod are slidably engaged.

[0011] The receiving assembly includes a support net and a receiving bin. The support net is fixedly connected to the workbench and is located on the inner side wall of the workbench. The receiving bin is fixedly connected to the workbench and is located below the workbench.

[0012] The clamping assembly includes a right-angle plate, a cylinder, and a pressure plate. The right-angle plate is fixedly connected to the worktable and located above the worktable. The cylinder is fixedly connected to the right-angle plate and located above the right-angle plate. The pressure plate is fixedly connected to the cylinder and located at the output end of the cylinder.

[0013] The present invention also provides a positioning and cutting method for processing plastic fuel tanks, comprising the following steps: The plastic fuel tank is placed on the support net and clamped and fixed using the cylinder and the pressure plate. The stepper motor and the drive motor are linked together to make the irregularly shaped blade cut holes in the plastic oil tank; The support net is used to collect the debris generated during the cutting process into the receiving bin, thus completing the cutting of the plastic oil tank.

[0014] This invention discloses a positioning and cutting device and method for processing plastic fuel tanks. In use, the plastic fuel tank is placed on the worktable and fixed using the clamping assembly. The driving component moves the slider downwards along the inner wall of the side column. Simultaneously, the driving motor is activated, causing the quick-release head to rotate, thereby driving the shaped blade to cut holes in the plastic fuel tank. The material collection assembly collects the debris generated during the cutting process, and the auxiliary component improves the stability of the mounting bracket as it moves downwards. This method solves the problem of large human cutting errors, which easily lead to deviations from the design reference for the opening position. This not only affects the installation of subsequent components but may even cause the entire fuel tank to be scrapped due to incorrect positioning, resulting in economic losses.

[0026] This invention provides a positioning and cutting device for processing plastic fuel tanks, including a worktable 101, a cutting assembly, a clamping assembly, and a receiving assembly. The cutting assembly includes a side column 102, a slider 103, a mounting bracket 104, a drive motor 105, a quick-release head 106, a shaped blade 107, a slide block 108, a locking bolt 109, a support frame 110, a buffer pad 111, a driving component, an auxiliary component, and a reinforcing component. The driving component includes a threaded rod 112 and a stepper motor 113. The auxiliary component includes a slide rod 114 and a connecting ring 115. The receiving assembly includes a support net 116 and a receiving bin 117. The clamping assembly includes a right-angle plate 118, a cylinder 119, and a pressure plate 120. The reinforcing component includes a connecting frame 121, a roller body 122, and a side plate 123.

[0027] The cutting assembly, the clamping assembly, and the receiving assembly are respectively connected to the worktable 101; the side column 102 is fixedly connected to the worktable 101 and located above the worktable 101; the slider 103 is slidably connected to the side column 102 and located on the inner side wall of the side column 102; the mounting bracket 104 is fixedly connected to the slider 103 and located on the outer side wall of the slider 103; the drive motor 105 is detachably connected to the mounting bracket 104 and located above the mounting bracket 104; the quick-release head 106 is fixedly connected to the drive motor 105 and located at the output end of the drive motor 105; the shaped blade 107 is detachably connected to the quick-release head 106 and located below the quick-release head 106; the driving component is connected to the side column 102 and the slider 103 respectively; and the auxiliary component is connected to the mounting bracket 104 and the worktable 101 respectively.

[0028] In this embodiment, the plastic oil tank is placed on the workbench 101 and fixed using the clamping assembly. The driving component drives the slider 103 to move downward along the inner wall of the side column 102. At the same time, the drive motor 105 is started, causing it to rotate the quick-release head 106, thereby driving the irregular blade 107 to cut the plastic oil tank. The material collection assembly is used to collect the debris generated during the cutting process. The auxiliary component is used to improve the stability of the mounting bracket 104 as it moves downward. This method solves the problem that human cutting errors are large and can easily cause the opening position to deviate from the design benchmark. This not only affects the installation of subsequent components, but may even cause the entire oil tank to be scrapped due to incorrect positioning, resulting in economic losses.

[0029] Furthermore, the slide 108 is detachably connected to the quick-release head 106 and is located below the quick-release head 106. The slide 108 is in contact with the shaped blade 107, and the locking bolt 109 passes through the shaped blade 107 and is threadedly connected to the slide 108.

[0030] In this embodiment, the slide 108 can move laterally with the quick-release head 106. After being adjusted to a suitable position, it is locked and fixed by the locking bolt 109, thereby realizing the adjustment of the irregular blade 107 and making it convenient for workers to cut holes of different diameters.

[0031] Furthermore, the support frame 110 is fixedly connected to the workbench 101 and is located above the workbench 101, and the buffer pad 111 is fixedly connected to the support frame 110 and is located above the support frame 110.

[0032] In this embodiment, the support frame 110 is used to limit the downward movement distance of the mounting frame 104, and the buffer pad 111 is made of rubber material to relieve the pressure generated by the contact between the mounting frame 104 and the support frame 110, thereby extending the service life of the support frame 110.

[0033] Furthermore, the threaded rod 112 is rotatably connected to the side post 102 and is located on the inner side wall of the side post 102.

The output end of the stepper motor 113 is fixedly connected to the threaded rod 112 and is located above the threaded rod 112.

[0034] In this embodiment, the stepper motor 113 is started to drive the threaded rod 112 to rotate, and the slider 103 is driven to move downward along the side column 102 using the principle of the thread, thereby realizing the lifting and lowering of the irregular blade 107.

[0035] Furthermore, the slide bar 114 is fixedly connected to the worktable 101 and located above the worktable 101, the connecting ring 115 is fixedly connected to the mounting bracket 104 and located on one side of the mounting bracket 104, and the connecting ring 115 is slidably engaged with the slide bar 114.

[0036] In this embodiment, the connecting ring 115 is used to assist the mounting bracket 104 in moving along the slide bar 114, thereby improving the stability of the mounting bracket 104 during lifting and lowering and avoiding swaying.

[0037] Furthermore, the support net 116 is fixedly connected to the workbench 101 and is located on the inner side wall of the workbench 101, and the receiving bin 117 is fixedly connected to the workbench 101 and is located below the workbench 101.

[0038] In this embodiment, the support net 116 is used to place the plastic oil tank, and can also use the gaps between the mesh plates to collect the debris generated during the cutting process to the receiving bin 117, which is convenient for workers to clean up later.

[0039] Furthermore, the right-angle plate 118 is fixedly connected to the workbench 101 and located above the workbench 101, the cylinder 119 is fixedly connected to the right-angle plate 118 and located above the right-angle plate 118, and the pressure plate 120 is fixedly connected to the cylinder 119 and located at the output end of the cylinder 119.

[0040] In this embodiment, the cylinder 119 is activated, causing it to move the pressure plate 120 towards each other, clamping the outer wall of the plastic oil tank to fix the plastic oil tank, making it easier for the irregular blade 107 to cut.

[0041] Furthermore, the cutting assembly also includes a reinforcing member, which is connected to the side post 102 and the mounting bracket 104 respectively. The reinforcing member includes a connecting frame 121, a roller body 122, and a side plate 123. The side plate 123 is fixedly connected to the side post 102 and is located on the outer side wall of the side post 102. The connecting frame 121 is fixedly connected to the mounting bracket 104 and is located on one side of the mounting bracket 104. The roller body 122 is rotatably connected to the connecting frame 121 and is located on one side of the connecting frame 121. The roller body 122 and the side plate 123 are rotatably engaged.

[0042] In this embodiment, when the mounting bracket 104 moves downward, the roller body 122 on one side of the connecting bracket 121 rolls on the side plate 123, and the hook structure formed is used to improve the stability of the mounting bracket 104 lifting and lowering, share the pressure of the contact part between the slider 103 and the side column 102, and extend the service life of the slider 103.

[0044] Figure 5 This is a flowchart illustrating the steps of the positioning and cutting method for processing plastic fuel tanks according to the present invention. (Refer to...) Figure 5 The method includes the following steps: S100 Place the plastic oil tank onto the support net 116 and clamp and fix it using the cylinder 119 and the pressure plate 120; S200 uses the stepper motor 113 and the drive motor 105 to work together to make the irregular blade 107 cut holes in the plastic oil tank; S300 uses the support net 116 to collect the debris generated during the cutting process into the receiving bin 117, thus completing the cutting of the plastic oil tank.

[0045] In this embodiment, the plastic fuel tank is placed on the support net 116 and clamped and fixed using the cylinder 119 and the pressure plate 120. The stepper motor 113 and the drive motor 105 are linked to make the irregular blade 107 cut holes in the plastic fuel tank. The support net 116 collects the debris generated during the cutting process into the receiving bin 117, thus completing the cutting of the plastic fuel tank. This method solves the problem that human cutting errors are large and can easily cause the opening position to deviate from the design benchmark. This not only affects the installation of subsequent components, but may even cause the entire fuel tank to be scrapped due to incorrect positioning, resulting in economic losses.
