[0026] Figure 1-3 The utility model provides a clamping device for automobile assembly, including a base 1, two first telescopic cylinders 2, and two clamping plates 3. The two first telescopic cylinders 2 are installed on the base 1 through a mounting plate 7, and the telescopic rods of the two are arranged relatively to each other and are connected and fixed to the corresponding clamping plates 3. The utility model also includes a rotating mechanism and a lifting plate 4. The rotating mechanism is arranged on the clamping plate 3 to drive the clamping plate 3 to rotate longitudinally. A groove is opened on the base 1. The lifting mechanism is arranged on the base 1, and its lifting end is connected to the lifting plate 4 to drive the lifting plate 4 to move up and down in the groove.

[0027] In this embodiment, the automobile parts to be assembled are placed on the lifting plate 4, and the two first telescopic cylinders 2 (the first telescopic cylinders 2 are air cylinders or electric push rods) are started. The extension of the telescopic rods of the first telescopic cylinders 2 can drive the two clamping plates 3 to approach each other until they abut against the two ends of the automobile parts, so that the automobile parts can be clamped and fixed. When the automobile parts need to be turned over, the lifting plate 4 is driven down by the jacking mechanism, and then the two clamping plates 3 are driven to rotate by the rotating mechanism, so that the automobile parts can be turned over, which is convenient for subsequent processing of multiple surfaces. After the turning is completed, the lifting plate 4 is driven up again by the jacking mechanism until the lifting plate 4 contacts the bottom end of the automobile parts, which plays a supporting role for the automobile parts.

[0028] Specifically, the rotating mechanism includes a rotating column 51 and a limiting assembly. The rotating column 51 is fixed on the clamping plate 3 and is rotatably connected to the telescopic rod of the first telescopic cylinder 2 through a bearing. The limiting assembly is located below the rotating column 51. The rotating column 51 is provided with a plurality of limiting grooves 525 adapted to the limiting assembly, so that the limiting assembly can limit the rotating column 51 at multiple angles. More specifically, the limiting assembly includes a limiting seat 521, a limiting column 522, a spring 523 and a pressing block 524. The limiting seat 521 is located below the rotating column 51. A cavity is provided in the limiting seat 521. The limiting column 522 penetrates the upper end of the limiting seat 521 and extends into the cavity. One end of the spring 523 abuts against the limiting column 522 and the other end is connected to the base 1. The limiting seat 521 is provided with an opening. The pressing block 524 passes through the opening and is fixedly connected to the limiting column 522. The limiting column 522 is adapted to the limiting groove 525.

[0029] When the rotating column 51 rotates to the specified position, the limiting column 522 extends into the corresponding limiting groove 525, so that the rotating column 51 can be limited and fixed. If the rotating column 51 needs to be further rotated later, the staff presses the pressing block 524, the spring 523 is compressed, and the limiting column 522 disengages from the limiting groove 525. At this time, the rotating column 51 can continue to rotate.

[0030] Preferably, a plurality of anti-slip protrusions are provided on the surface of the pressing block 524 .

[0031] The anti-slip protrusions can increase the friction force on the surface of the pressing block 524 .

[0032] Specifically, the lifting mechanism includes a plurality of second telescopic cylinders 61 . The second telescopic cylinders 61 are all disposed in the grooves, and the telescopic rods of the second telescopic cylinders 61 are all connected and fixed to the lifting plate 4 .

[0033] The second telescopic cylinder 61 is started (the second telescopic cylinder 61 is a hydraulic cylinder or an electric cylinder), and the telescopic rod of the second telescopic cylinder 61 is extended and retracted to drive the lifting plate 4 to move up and down in the groove.

[0034] The working principle of this utility model:

[0035] The automobile parts to be assembled are placed on the lifting plate 4, and the two first telescopic cylinders 2 are started. The extension of the telescopic rod of the first telescopic cylinder 2 can drive the two clamping plates 3 to approach each other until they abut against the two ends of the automobile parts, so that the automobile parts can be clamped and fixed. When the automobile parts need to be flipped, the second telescopic cylinder 61 is started, and the contraction of the telescopic rod of the second telescopic cylinder 61 can drive the lifting plate 4 to descend in the groove. Then the staff presses the pressing block 524, the spring 523 is compressed, and the limiting column 522 is separated from the limiting groove 525. At this time, the rotating column 51 can drive the two clamping plates 3 and the automobile parts to continue to rotate. After rotating to the specified position, the staff releases the pressing block 524. Under the action of the spring 523, the limiting column 522 extends into the corresponding limiting groove 525, and the rotating column 51 can be limited and fixed, which is convenient for subsequent processing of multiple surfaces. After the flipping is completed, the lifting plate 4 is driven to rise again by the second telescopic cylinder 61 until the lifting plate 4 contacts the bottom end of the automobile parts, which plays a supporting role for the automobile parts.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
