Description

Technical Field

[0001] This utility model relates to the field of automotive radiators, and in particular to a side-biting device for radiator side panels. Background Technology

[0002] A car radiator is an important component in a vehicle, used to dissipate the heat generated during operation. To improve the radiator's cooling efficiency, a fan is usually installed to accelerate heat removal. A side panel is typically required for mounting the fan on the radiator.

[0003] Chinese Patent Publication No. CN215109130U discloses a side-biting mechanism for an automotive radiator side panel. The mechanism includes a biting support on the top of an operating platform, a fixed base mounted on a mounting groove at the right end of the top of the operating platform, a lifting cylinder mounted on the fixed base, a support column mounted on the top of the lifting cylinder via the fixed base, a positioning screw mounted on one side of a slider, a crossbar slidably mounted on the support column via the slider, a driving hydraulic cylinder connected to the top of an upper template, the upper template mounted below the driving hydraulic cylinder via a first guide column and a second guide column, an alignment plate mounted below the upper template, a lower template mounted below the alignment plate, and a biting blade mounted at the bottom of the lower template. This side-biting device can accurately position the biting area of ​​the automotive radiator side panel by aligning the upper and lower templates, improving biting efficiency, providing a good biting effect, and facilitating operation.

[0004] However, the above technical solution has the following shortcomings: the device will generate vibration when performing edge biting treatment on the side plate. Since the guide fixing plate only performs simple limiting clamping by the mutual squeezing of the first limiting frame and the second limiting frame, the vibration generated during edge rolling can easily cause the placement table to shift, thereby reducing the processing quality of the side biting part of the side plate. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a side-biting device for radiator side panels, which can avoid the displacement of the processing platform caused by vibration during the biting process of radiator side panels, thereby ensuring the processing quality of the biting.

[0006] The technical solution of this utility model is a side-biting device for a radiator side plate, including a worktable and a clamping mechanism; a placement plate is provided on the worktable; the clamping mechanism includes two symmetrically distributed limiting clamps, a rotating shaft rotatably connected inside the worktable, a driving component for driving the limiting clamps to move horizontally, and a locking component for restricting the axial rotation of the rotating shaft. The locking component includes a rectangular block slidably disposed inside the rotating shaft, a first spring with its two ends respectively disposed on the rectangular block and the worktable, a connecting shaft rotatably connected inside the rectangular block, a connecting plate disposed on the connecting shaft, and two symmetrically disposed pins on the connecting plate. The worktable is provided with a groove for the pins to be inserted.

[0007] Preferably, a retaining ring is coaxially provided on the connecting shaft, and the retaining ring is rotatably disposed inside the rotating shaft.

[0008] Preferably, the rotating shaft is provided with two limiting rods, and a positioning post is coaxially provided on the limiting rod. The connecting plate is provided with a limiting hole for the positioning post to be inserted, and a first grip is provided on the connecting plate.

[0009] Preferably, the rotating shaft is provided with a first threaded portion and a second threaded portion with opposite thread directions. The drive assembly includes two symmetrically distributed threaded blocks that are threadedly connected to the first threaded portion and the second threaded portion respectively, a connecting rod with both ends respectively provided on the threaded blocks and the limiting clamping plate, and a rotating wheel provided on the rotating shaft. The threaded blocks are slidably connected to the worktable.

[0010] Preferably, a stabilizing mechanism is provided on the workbench. The stabilizing mechanism includes a support frame on the workbench, a pull rod slidably mounted on the support frame, a second handle and a pressure plate respectively mounted on both ends of the pull rod, and a second spring mounted on the support frame and the pressure plate respectively and sleeved on the outside of the pull rod.

[0011] Preferably, the pressure plate is provided with multiple rollers arranged in a linear array.

[0012] Preferably, a mounting frame is provided on the workbench, and a hydraulic cylinder is provided on the mounting frame. The hydraulic cylinder drives a seaming machine located above the placement plate.

[0013] Preferably, the seam-sealing machine is provided with two guide rods that are vertically slidably connected to the mounting bracket.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] This utility model can quickly fix the placement plate at the processing position of the worktable through the set drive component, and the set locking component can restrict the axial rotation of the connecting shaft, so as to avoid the vibration generated by the edge biting knife during the edge biting processing of the side plate, which would cause the rotating shaft to deflect, and then the threaded block would drive the limit clamping plate to shift, thus affecting the processing accuracy of the edge biting of the side plate. It has good practicality and is simple and convenient to operate. Attached Figure Description

[0021] Example 1

[0022] like Figure 1-Figure 4 As shown in the figure, the heat sink side plate edge biting device proposed in this embodiment includes a workbench 1 and a clamping mechanism; a placement plate 2 is provided on the workbench 1.

[0023] like Figure 1-Figure 3 As shown, the clamping mechanism includes two symmetrically distributed limiting clamps 3, a rotating shaft 4 rotatably connected inside the worktable 1, a driving assembly for driving the limiting clamps 3 to move horizontally, and a locking assembly for restricting the axial rotation of the rotating shaft 4. The locking assembly includes a rectangular block 8 slidably disposed inside the rotating shaft 4, a first spring 16 with its two ends respectively disposed on the rectangular block 8 and the worktable 1, a connecting shaft 9 rotatably connected inside the rectangular block 8, a connecting plate 11 disposed on the connecting shaft 9, and two inserts 12 symmetrically disposed on the connecting plate 11. The worktable 1 is provided with a groove for the inserts 12 to be inserted.

[0024] like Figure 3 As shown, a retaining ring 10 is coaxially mounted on the connecting shaft 9. The retaining ring 10 is rotatably mounted inside the rotating shaft 4 and is used to limit the axial position of the connecting shaft 9 within the rectangular block 8. Two limiting rods 13 are provided on the rotating shaft 4, and positioning pins 14 are coaxially mounted on the limiting rods 13. The connecting plate 11 is provided with limiting holes 15 for the positioning pins 14 to be inserted, and a first grip 17 is provided on the connecting plate 11.

[0025] like Figure 2 As shown, the rotating shaft 4 is provided with a first threaded part and a second threaded part with opposite screw directions. The drive assembly includes two symmetrically distributed threaded blocks 5 that are threadedly connected to the first threaded part and the second threaded part respectively, a connecting rod 6 with both ends respectively set on the threaded blocks 5 and the limiting clamping plate 3, and a rotating wheel 7 set on the rotating shaft 4. The threaded blocks 5 are slidably connected to the worktable 1.

[0026] In this embodiment, when it is necessary to fix the placement plate 2, the placement plate 2 is first placed at the processing position of the workbench 1, and then the rotating wheel 7 is held and the rotating shaft 4 is rotated. The first threaded part and the second threaded part are screwed with the two threaded blocks 5, and then the two threaded blocks 5 drive the two limiting clamps 3 to move closer to each other until the limiting clamps 3 fix the placement plate 2 at the processing position.

[0027] The axial rotation of the rotating shaft 4 can be restricted by the insertion post 12 set on the connecting plate 11 and the groove on the worktable 1, avoiding the vibration generated during edge biting that causes the rotating shaft 4 to deflect, which in turn causes the threaded block 5 to drive the limiting clamping plate 3 to shift. Before rotating the rotating shaft 4, hold the first handle 17 and pull the connecting plate 11. The connecting plate 11 drives the rectangular block 8 to move through the connecting shaft 9 and the retaining ring 10. When the insertion post 12 disengages from the groove, rotate the connecting plate 11, then align the limiting hole 15 with the positioning post 14 on the limiting rod 13 and release the first handle 17. Under the action of the first spring 16, the positioning post 14 is inserted into the limiting hole 15, and the connecting shaft 9 can be rotated. When the limiting clamping plate 3 is fixed to the placement plate 2, the insertion post 12 is inserted into the groove. It has good practicality and is simple and convenient to operate.

[0028] Example 2

[0029] like Figure 1 and Figure 4 As shown, the heat sink side plate edge-biting device proposed in this embodiment has a stabilizing mechanism on the workbench 1 compared to the first embodiment. The stabilizing mechanism includes a support frame 18 on the workbench 1, a pull rod 19 slidably mounted on the support frame 18, a second handle 20 and a pressure plate 21 respectively mounted on both ends of the pull rod 19, and a second spring 22 mounted on the support frame 18 and the pressure plate 21 respectively and sleeved on the outside of the pull rod 19. The pressure plate 21 is provided with a plurality of linearly arrayed rollers 23.

[0030] In this embodiment, when the side plate is placed in front of the placement plate 2, the pull rod 19 is pulled upward by the second handle 20. The pull rod 19 drives the pressure plate 21 to rise and compresses the second spring 22. After the side plate is placed, the second handle 20 is slowly released. Under the action of the second spring 22, the pressure plate 21 presses down on the side plate, ensuring the stability of the pressure plate 21 in the vertical direction. At the same time, the rollers 23 facilitate the horizontal movement of the side plate.

[0031] Example 3

[0032] like Figure 1 As shown in this embodiment, a side-edge biting device for a radiator side panel is proposed. Compared to Embodiment 1, in this embodiment, a mounting frame 24 is provided on the workbench 1, and a hydraulic cylinder 25 is provided on the mounting frame 24. The hydraulic cylinder 25 drives an edge biting machine 26 located above the placement plate 2. When the side panel to be processed is correctly placed on the placement plate 2, the edge biting machine 26 is driven to descend by the hydraulic cylinder 25, and the edge biting knife (not shown) performs edge biting processing on the side panel to be processed. The edge biting machine 26 is provided with two guide rods 27 that are vertically slidably connected to the mounting frame 24. The guide rods 27 guide the lifting and lowering of the edge biting machine 26.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
