Detailed Embodiment
[0013] The following further describes the utility model with reference to the drawings.
[0014] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further details the utility model in combination with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.
[0015] Refer to Figure 1 , a clamping mechanism for a roller workpiece used in boring machine processing, including a base 1, a pair of vertical bearing blocks 2 are arranged on the base 1, a right-hand and left-hand screw 3 is arranged between the vertical bearing blocks 2, a handwheel 4 is arranged at one end of the right-hand and left-hand screw 3, a slide rail 5 is arranged between the vertical bearing blocks 2, a pair of slide blocks 6 are arranged on the slide rail 5, the right-hand and left-hand screw 3 is threadedly connected to a pair of clamping blocks 7, the bottoms of the clamping blocks 7 are respectively fixedly connected to the slide blocks 6, the opposite sides of the clamping blocks 7 are respectively an arc surface and a boring surface, the arc surfaces form a clamping groove 8 in combination, the boring surfaces form a boring extension groove 9 in combination, an installation groove 10 is opened inside the clamping block, and an internal clamping mechanism 11 is arranged in the installation groove 10. Specifically, place the roller workpiece in the clamping groove 8, and at the same time make the position of the boring prefabricated hole located inside the boring extension groove 3, then rotate the handwheel 4, the clamping blocks 7 move relatively through the rotation of the right-hand and left-hand screw 3, clamp the roller workpiece, realize the first clamping, and then realize the second clamping through the internal clamping mechanism 11.
