DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example 1

[0021] like Figure 1As shown, this embodiment includes a connecting rod base 10 and a fixture base 100 arranged above the connecting rod base 10; in this embodiment, the connecting rod base 10 is installed on the pull rod of the lathe; and the fixture base 100 is installed on the base of the lathe.

[0022] like Figure 2 As shown, a connecting rod pressure cover 20 is provided on the connecting rod base 10. In this embodiment, the connecting rod pressure cover 20 is fixedly connected to the connecting rod base 10 by bolts.

[0023] like Figure 3 As shown, an inner groove 21 is provided at the bottom of the connecting rod pressure cover 20, and the inner groove 21 is an elliptical groove; a first through hole 22 connected to the inner groove 21 is provided at the top of the connecting rod pressure cover 20; in this embodiment, the first through hole 22 is an elliptical through hole; and the diameter of the inner groove 21 is greater than the diameter of the first through hole 22.

[0024] like Figure 4 As shown, a connecting rod guide block 25 is provided in the inner groove 21. The connecting rod guide block 25 is smaller than the inner groove 21, so that the connecting rod guide block 25 can slide left and right in the inner groove 21. At the same time, it is fixedly connected to the connecting rod base 10 by bolts through the connecting rod pressure cover 20, which can limit the displacement of the connecting rod guide block 25 in the inner groove 21 and on the connecting rod base 10.

[0025] A connecting rod 26 is disposed on the connecting rod guide block 25. In the present embodiment, the connecting rod guide block 25 and the connecting rod 26 are integrally formed.

[0026] like Figure 5-6 As shown, the clamp base 100 is provided with a second through hole 110 corresponding to the first through hole 22, and the clamp base 100 is provided with a transverse slider guide rail 120. In this embodiment, the transverse slider guide rail 120 extends from the upper end of the second through hole 110;

[0027] The transverse slider rail 120 is provided with a slider 130, so that the slider 130 can slide on the transverse slider rail 120, and a threaded hole is provided on the slider 130, and the transverse slider rail 120 also has a threaded hole, so that the slider 130 can be fixed on the transverse slider rail 120 by screws;

[0028] The slider 130 is provided with a shaft sleeve 140, and the shaft sleeve 140 is provided with an elastic chuck 150;

[0029] A guide rail stopper 160 is provided at one end of the transverse slider guide rail 120, and a gauge block 170 is provided between the guide rail stopper 160 and the slider 130; in this embodiment, after the processing eccentricity is adjusted, the slider 130 can be fixed on the transverse slider guide rail 120 by screws, and the gauge block 170 can be removed from between the guide rail stopper 160 and the guide rail stopper 160.

[0030] When replacing products with different eccentricities, the slider 130 can be moved on the transverse slider guide rail 120 by loosening the screws, so that the gauge blocks 170 of different sizes can be replaced to adjust the processing eccentricity.

[0031] The upper end of the connecting rod 26 passes through the first through hole 22, the second through hole 110, the transverse slider guide 120, the slider 130, the sleeve 140 in sequence and is fixedly connected to the bottom of the elastic clamp 150; thereby, the connecting rod base 10 is pulled by the pull rod of the lathe, so that the connecting rod base 10 pulls the elastic clamp 150 to clamp the product 200 to be processed.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the technical solution of the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the spirit and scope of the technical solution of each embodiment of the utility model.
