[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] like Figures 1-3 As shown, a CNC indexing plate position adjustment mechanism is disclosed, comprising a fixed base 1, a movable base 2 on the upper surface of the fixed base 1, and both the fixed base 1 and the movable base 2 having hollow bottoms. An indexing plate body 3 is fixedly mounted on the upper surface of the movable base 2. A first lead screw 4 is rotatably connected to the two side walls of the movable base 2 via bearings, and an internal thread block 5 is rotatably connected to the surface of the first lead screw 4 via a thread. A strip-shaped opening 101 is opened on the top wall of the fixed base 1. A second lead screw 7 is rotatably connected to the side wall of the fixed base 1 via bearings. An L-shaped rod 6 is rotatably connected to the surface of the second lead screw 7 via a thread. The end of the L-shaped rod 6 away from the second lead screw 7 passes through the strip-shaped opening 101 and is fixedly connected to the lower surface of the internal thread block 5. The L-shaped rod 6 is slidably connected to the strip-shaped opening 101. A collection box 9 is provided inside the fixed base 1. A side opening 102 is opened on the side of the fixed base 1 away from the second lead screw 7. One end of the collection box 9 passes through the side opening 102 and is fixedly connected to a side plate 10.

[0023] Both the end of the first lead screw 4 located outside the movable seat 2 and the end of the second lead screw 7 located outside the fixed seat 1 are fixed with nuts.

[0024] The second lead screw 7 and the strip opening 101 are both perpendicular to the first lead screw 4.

[0025] By installing nuts on the ends of the first lead screw 4 and the second lead screw 7, it is easy to rotate the first lead screw 4 and the second lead screw 7 through the nuts. When the second lead screw 7 is rotated, it drives the L-shaped rod 6 to move laterally along the strip opening 101, thereby moving the internal thread block 5 and changing the position of the moving seat 2. When the first lead screw 4 is rotated, since the internal thread block 5 cannot move along the direction of the first lead screw 4, the moving seat 2 will move along the direction of the first lead screw 4. Therefore, by rotating the first lead screw 4 and the second lead screw 7, the moving seat 2 can be moved in both the X and Y directions, thereby adjusting the horizontal position of the indexing plate body 3.

[0026] The fixed seat 1 is internally fixed with a guide rod 8, and the guide rod 8 is parallel to the second screw rod 7, the guide rod 8 penetrates through the L-shaped rod 6 and is in sliding connection with the L-shaped rod 6.

[0027] The guide rod 8 can stabilize and guide the movement of the L-shaped rod 6.

[0028] The side plate 10 is fixed with a handle 11 away from the fixed seat 1, and the top end of the side plate 10 and the surface of the fixed seat 1 are both fixed with a magnet 12.

[0029] Through the attraction of the two magnets 12, the side plate 10 can be attached to the outer wall of the fixed seat 1, so that the collecting box 9 is fixed at the bottom of the fixed seat 1, and the collecting box 9 can be directly pulled out from the bottom of the fixed seat 1 through the handle 11, which is convenient for cleaning the debris in the collecting box 9.

[0030] The moving seat 2 is provided with a plurality of hemispherical grooves 21 at the bottom of the side edge, and each hemispherical groove 21 is rotatably connected with a ball 22, and the bottom end of the ball 22 is attached to the upper surface of the fixed seat 1.

[0031] The balls 22 can support the moving seat 2 at the bottom of the moving seat 2, so that the downward force acting on the L-shaped rod 6 is avoided, and the rolling of the balls 22 can reduce the friction between the moving seat 2 and the upper surface of the fixed seat 1.

[0032] The fixed seat 1 is fixed with two mounting plates 13 at the bottom of the two sides, and the mounting plates 13 are provided with mounting holes. The adjusting mechanism can be mounted on the lathe through the mounting holes, and the mounting method is as follows: align the mounting holes on the mounting plates 13 with the mounting holes on the lathe, and screw the bolts into the mounting holes.

[0033] Working principle: when in use, first install the adjusting mechanism on the lathe through the mounting plates 13, when it is necessary to adjust the position of the index plate body 3, rotate the first screw rod 4 or the second screw rod 7, rotating the second screw rod 7 drives the moving seat 2 to move along the direction of the strip-shaped opening 101, and rotating the first screw rod 4 drives the moving seat 2 to move along the direction of the first screw rod 4, thereby realizing the movement of the index plate body 3 in two directions. When the lathe processes the workpiece fixed on the surface of the index plate body 3, part of the debris falls on the surface of the fixed seat 1, the moving seat 2 and the index plate body 3, and part of the debris falls into the collecting box 9 through the strip-shaped opening 101. When cleaning, the debris on the surface of the fixed seat 1, the moving seat 2 and the index plate body 3 is swept into the strip-shaped opening 101, and the debris is collected by the collecting box 9. After use, the collecting box 9 is pulled out from the bottom of the fixed seat 1, and the debris in the collecting box 9 is poured out.

[0034] The preferred embodiments disclosed above are only used to help describe the utility model. The preferred embodiments do not describe all the details and do not limit the utility model to the specific implementation. Obviously, according to the content of the specification, many modifications and changes can be made. The specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the utility model, so that the person skilled in the art can well understand and utilize the utility model. The utility model is limited by the claims and the whole scope and equivalents thereof.
