Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile component clamps, and more specifically, to an automobile component clamp. Background Art
[0002] In existing automobile manufacturing technology, automobile parts fixtures are special tools used to fix parts during assembly, processing or testing. They ensure the correct position and stability of parts during operation. However, since many automobile parts, such as body panels, hoods, fenders, etc., often have complex curved shapes, this poses a challenge to the design and use of fixtures. When fixing these curved parts, if only a single point is used for fixing, it is easy to cause excessive local pressure, which in turn causes deformation or damage to the parts. This single-point fixing method not only affects the dimensional accuracy and surface quality of the parts, but may also shorten the service life of the parts and even affect the performance and safety of the entire vehicle.

[0028] See also Figure 1-5A clamp for automobile parts includes a support frame 1, which is installed on an external device. An adjustment mechanism is arranged on the support frame 1, and the adjustment mechanism includes a moving mechanism, a connecting rod 2, a fixed sleeve 3, a push rod 4, an intermediate sleeve 5, a pushing mechanism, a side plate 6 and a pulling sleeve 7. The moving mechanism is cooperatively connected to the support frame 1 and the connecting rod 2, the fixed sleeve 3 is installed on the connecting rod 2, a telescopic hole 8 is opened in the fixed sleeve 3, and the push rod 4 is slidably connected in the telescopic hole 8, the intermediate sleeve 5 is installed in the fixed sleeve 3, and a lateral groove 9 is opened on the side wall of the intermediate sleeve 5, and the lateral groove 9 is slidably connected to the side plate 6, and the pushing mechanism is cooperatively connected to the fixed sleeve 3 and the side plate 6 The pull sleeve 7 is installed on the side plate 6, and the pull sleeve 7 is slidably connected to the side wall of the push rod 4. The pushing mechanism includes a threaded section 10 and a thrust bearing 11. The threaded section 10 is threadedly connected in the middle sleeve 5, and the thrust bearing 11 is fitted on the threaded section 10. A hexagonal groove 12 is opened in the threaded section 10, and the hexagonal groove 12 and the threaded section 10 are coaxially arranged. A plurality of reducing platforms 13 are provided on the side wall of the fixed sleeve 3, and the plurality of reducing platforms 13 are equidistantly arranged. A slider 14 is slidably provided on each reducing platform 13, and the side plate 6 is connected to the slider 14. Each slider 14 is provided with a push spring 15, and the plurality of push springs 15 respectively abut against the thrust bearing 11.
[0029] In this embodiment, when it is necessary to adjust the sliding force of multiple push rods 4, first insert the hexagonal wrench through the fixing sleeve 3 into the hexagonal groove 12, and then by rotating the threaded section 10, the thrust bearing 11 converts the thrust into a vertical thrust, and then the push spring 15 can drive the slider 14 to slide along the diameter reducing platform 13, so that multiple sliders 14 will shrink accordingly, and multiple pull sleeves 7 will also shrink accordingly. Since the pull sleeve 7 is slidably connected to the push rod 4, the sliding resistance of the push rod 4 can be increased. Then, when the push rod 4 contacts the automotive parts, when a single push rod 4 exceeds the sliding resistance, the push rod 4 will slide backward, and then multiple push rods 4 are respectively pressed against the side walls of the automotive parts, thereby completing the clamping process. Therefore, it can effectively adapt to the curved surface of the automotive parts without being performed, and can also reduce the pressure at a single point, thereby improving the use effect.
[0030] See also Figure 1 As an implementation method of the moving mechanism: the moving mechanism includes a pressing plate 16 and a folding plate 17, the pressing plate 16 is rotatably connected to the support frame 1, the connecting rod 2 is installed on the pressing plate 16, the folding plate 17 is rotatably connected to the support frame 1, a cylinder 18 is rotatably provided on the support frame 1, the protruding end of the cylinder 18 is rotatably connected to the folding plate 17, a pressing block 19 is provided on the folding plate 17, and the pressing block 19 abuts against the pressing plate 16.
[0031] More specifically, when the automobile parts need to be clamped, the folding plate 17 is driven to rotate by the cylinder 18. Since the folding plate 17 is rotatably connected to the support frame 1, it will drive the pressure block 19 to press on the pressure plate 16, and then drive the pressure plate 16 to rotate along the support frame 1, so that the push rod 4 contacts the automobile parts, thereby completing the clamping process.
[0032] In summary, when the overall equipment is in use or running: when it is necessary to adjust the sliding force of multiple push rods 4, first insert the hexagonal wrench through the fixing sleeve 3 into the hexagonal groove 12, and then by rotating the threaded section 10, the thrust bearing 11 converts the thrust into a vertical thrust, and then the push spring 15 can drive the slider 14 to slide along the diameter reducing platform 13, so that multiple sliders 14 will shrink accordingly, and multiple pull sleeves 7 will also shrink accordingly. Since the pull sleeve 7 is slidably connected to the push rod 4, the sliding resistance of the push rod 4 can be increased. Then, when the push rod 4 contacts the automotive parts, when a single push rod 4 exceeds the sliding resistance, the push rod 4 will slide backwards, and then multiple push rods 4 are respectively pressed against the side walls of the automotive parts, thereby completing the clamping process. Therefore, it can effectively adapt to the curved surface of the automotive parts without being performed, and can also reduce the pressure at a single point, thereby improving the use effect.
[0033] When the automobile parts need to be clamped, the folding plate 17 is rotated by the cylinder 18. Since the folding plate 17 is rotatably connected to the support frame 1, it will drive the pressure block 19 to press on the pressure plate 16, and then drive the pressure plate 16 to rotate along the support frame 1, so that the push rod 4 contacts the automobile parts, thereby completing the clamping process.
