Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] EMBODIMENT

[0024] Please refer to Figures 1 to 4 For the embodiments of the present application, the embodiments provide a technical solution: a hole expanding mechanism, comprising

[0025] The frame 31 is fixedly installed on the inner side of the conical hole end milling machine frame 2, the speed reducer motor 32 is installed on the bottom surface of the frame 31, the rotating disc 33 is rotatably installed on the top of the frame 31 and connected with the output shaft of the speed reducer motor 32, the inclined support block 34 is fixed on the top of the rotating disc 33, the hole expanding tool bit 35 is fixed on the side surface of the inclined support block 34 and protrudes from the top of the frame 31, the top end of the hole expanding tool bit 35 is inserted into the conical hole at the bottom of the workpiece main body 4, and in actual operation, the speed reducer motor 32 drives the rotating disc 33 to rotate after being started, and the hole expanding tool bit 35 at the top end of the inclined support block 34 will cut the conical hole at the bottom of the workpiece main body 4 when the rotating disc 33 rotates, so as to achieve the hole expanding effect.

[0026] A workpiece clamping structure of a conical hole end milling machine applied to a hole expanding mechanism, comprising

[0027] The guide sleeve 12 is welded on the side of the taper hole end milling machine rack 2, the sliding rod 11 is slidably arranged on the side of the taper hole end milling machine rack 2 and penetrates the guide sleeve 12, the movable plate 13 is welded on the bottom surface of the sliding rod 11, the nut seat plate 15 is welded on the bottom of the movable plate 13, the threaded rod 14 is screwed through the nut seat plate 15 and is rotationally connected with the movable plate 13 at the top end, the T-shaped shaft block 19 is welded on the top surface of the sliding rod 11, the rotating sleeve 16 is rotatably arranged on the T-shaped shaft block 19, and the pressing plate 17 is welded on the side of the rotating sleeve 16 and is pressed on the top of the workpiece body 4.

[0028] The adjusting assembly is arranged between the pressing plate 17 and the T-shaped shaft block 19, and includes the U-shaped shifting block 110 movably arranged on the top surface of the pressing plate 17, the limiting clamping rod 111 welded on the side of the U-shaped shifting block 110, and the plurality of limiting clamping grooves 112 formed in the top surface of the T-shaped shaft block 19, wherein the end of the limiting clamping rod 111 is inserted into one of the limiting clamping grooves 112 to stably limit the pressing plate 17. The adjusting assembly further includes the T-shaped sliding groove 113 formed in the top surface of the pressing plate 17, the T-shaped sliding block 114 and the spring 115 arranged in the T-shaped sliding groove 113, wherein the top end of the T-shaped sliding block 114 extends out of the top surface of the pressing plate 17 and is fixed with the U-shaped shifting block 110. Under the pushing action of the spring 115, the end of the limiting clamping rod 111 can be stably inserted into the limiting clamping groove 112 in the daily use process, so as to ensure the limiting stability of the pressing plate 17.

[0029] The end of the T-shaped sliding groove 113 is provided with a cylindrical recess, and one end of the spring 115 is inserted into the cylindrical recess, so that the spring 115 is limited and cannot deviate.

[0030] The surface of the rotating sleeve 16 is provided with a circular sleeve hole, and the rotating sleeve 16 is sleeved on the bottom end of the T-shaped shaft block 19 through the circular sleeve hole, so that the rotating sleeve 16 can rotate on the T-shaped shaft block 19 smoothly.

[0031] The bottom surface of the pressing plate 17 is further glued and fixed with an antiskid pad 18, and the antiskid pad 18 is closely attached to the top surface of the workpiece body 4. The antiskid pad 18 is made of rubber material and is provided with a plurality of antiskid grooves at the bottom, which can achieve a certain antiskid effect, so that the pressing plate 17 can stably fix the top of the workpiece body 4 and ensure the clamping stability.

[0032] The surface of the nut seat plate 15 is provided with a threaded hole, and the threads on the inner wall of the threaded hole are matched with the threads on the surface of the threaded rod 14, so that the threaded rod 14 can rotate and screw on the nut seat plate 15 smoothly.
