[0026] The mounting component 6, the middle part of the mounting component 6 is arranged inside the dividing table body 1, the mounting component 6 includes a connecting rod 61, a spring 62, and an L-shaped plate 63. The number of the connecting rods 61 is two, which are symmetrically arranged on both sides of the dividing table body 1, and the two ends of the spring 62 are respectively fixedly connected to the ends of the two connecting rods 61, and the top of the L-shaped plate 63 is fixedly installed to the side of the connecting rod 61.

[0027] The top of the indexing table body 1 is rotatably connected to a rotating platform 2, a driving motor 4 is fixedly installed on the side of the indexing table body 1, and a driving camshaft 5 is fixedly connected to the output end of the driving motor 4.

[0028] The mounting assembly 6 further includes a frame plate 60, an electric push rod 64, and a gasket 65. The side of the frame plate 60 is fixedly mounted to the outer surface of the indexing table body 1, and the outer surface of the connecting rod 61 is slidably mounted to the inner surface of the frame plate 60. The bottom of the electric push rod 64 is fixedly mounted to the inner surface of the bottom of the L-shaped plate 63, and the bottom of the gasket 65 is fixedly mounted to the top of the electric push rod 64.

[0029] By setting the gasket 65, after the L-shaped plate 63 is engaged with the cross section of the work surface, the electric push rod 64 can be controlled to extend to push the top gasket 65 upward so that the top of the gasket 65 contacts the bottom of the work surface, thereby improving the stability of the fixation of the L-shaped plate 63 and the work surface.

[0030] Embodiment 2: As shown in the attached Figure 3 , including a cam adjusting assembly 3, the top of the cam adjusting assembly 3 is fixedly mounted on the bottom of the rotating platform 2, and the bottom is meshed with the driving cam shaft 5.

[0031] Among them, the cam adjustment assembly 3 includes a cam plate 30, a connecting roller 31, a connecting plate 34, and a cam body 35. The top of the cam plate 30 is fixedly installed on the bottom of the rotating platform 2, the middle part of the connecting roller 31 is slidably installed on the inner surface of the cam plate 30, the middle part of the connecting plate 34 is threadedly connected to the bottom end of the connecting roller 31, the cam body 35 is arranged on the outside of the bottom end of the connecting roller 31, and the inner surface of the bottom of the cam body 35 is sleeved and installed on the outer surface of the connecting plate 34.

[0032] The cam adjustment assembly 3 further includes a latch post 32 and a spring 1 33.

[0033] By setting a spring 33, the spring 33 mainly uses its own elastic force, so that after the connecting roller 31 is moved by the paddle on the surface of the connecting roller 31, the connecting roller 31 is moved back to its original position through the reset effect of the spring 33, so that it is clamped and fixed with the top end of the connecting roller 31 inserted into the cam plate 30.

[0034] The working process of the utility model is as follows:

[0035] During the use of the rotary indexing table, the L-shaped plates 63 arranged on both sides of the bottom of the indexing table body 1 can be pulled outward, so that the connecting rod 61 connected to the top of the L-shaped plate 63 moves horizontally along the inner surface of the indexing table body 1 and the inner surface of the frame plate 60 until the L-shaped plate 63 is clamped with the cross section of the work table surface. At the same time, the L-shaped plate 63 on the other side is also processed in the same way. When the connecting rods 61 on both sides stretch the spring 2 62 connected in the middle, the spring 2 62 will also pull the connecting rods 61 connected at both ends due to its own elastic force, thereby clamping the L-shaped plate 63 with the work table surface on which the rotary indexing table is placed, making the fixing of the rotary indexing table convenient and easy to operate, thereby improving the actual use effect of the rotary indexing table.

[0036] When the internal cam body 35 needs to be adjusted and replaced, the cam plate 30 fixed to the rotating platform 2 by bolts can be separated first, and then, the block connected to the outer surface of the end of the latch column 32 close to the spring 33 can be pushed to separate the latch column 32 from the inside of the connecting roller 31. At this time, the connecting roller 31 and the cam body 35 installed at its bottom end can be moved downward to separate the connecting roller 31 from the inner surface of the cam plate 30, and then, the cam body 35 can be moved upward to slide along the outer surface of the connecting roller 31 and separate from the top of the connecting roller 31, and then the worn outer surface of the cam body 35 can be polished or the cam body 35 can be replaced to improve the convenience of adjusting the cam body 35.
