DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] Embodiment 1:

[0020] See also Figure 1-4: In this embodiment, a light machine tool spindle box includes a spindle box 1 and a straight plate 4. The left and right sides of the bottom of the spindle box 1 are respectively fixedly connected to the top of the straight plate 4. How to operate and use the spindle box 1 is already existing technology, and no further elaboration is given. The model is selected according to usage requirements. The output end of the spindle box 1 is connected to a mounting structure 2, and the outer wall of the straight plate 4 is connected to a supporting structure 3. The top of the supporting structure 3 is fixedly connected to the bottom of the spindle box 1, and the bottom of the supporting structure 3 is connected to a base plate 6.

[0021] The mounting structure 2 includes a first straight cylinder 201 and a straight rod 202. The rear end face of the first straight cylinder 201 is fixedly connected to the output end of the spindle box 1. The inner wall of the first straight cylinder 201 is plugged into the rear of the outer wall of the straight rod 202. The straight rod 202 can be pulled forward by force to detach from the inner wall of the first straight cylinder 201. The front of the straight rod 202 is fixedly connected to a second straight cylinder 203. The top of the first straight cylinder 201 is threadedly connected to a first screw rod 204. The first screw rod 204 is forced to rotate up and down through the top of the first straight cylinder 201. The top of the first screw rod 204 is fixedly connected to a handle 205, which is convenient for driving the first screw rod 204 to rotate;

[0022] The second straight cylinder 203 is initially installed by plugging the outer wall of the straight rod 202 into the inner wall of the first straight cylinder 201 through the installation structure 2. Then, the first screw rod 204 is rotated downward through the first straight cylinder 201 through the handle 205, so that the bottom of the outer wall of the first screw rod 204 is plugged into the top circular opening 7 of the straight rod 202 to complete the fixation. The installation of different components can be changed through the second straight cylinder 203, eliminating the use limitations of the light machine tool spindle box and reducing the difficulty of using the light machine tool spindle box.

[0023] The four corners of the top of the bottom plate 6 are respectively processed with round openings, and the supporting structure 3 includes a base frame 301 and a cylinder 302. The outer wall interlayer of the base frame 301 is slidably engaged with the outer wall of the straight plate 4, and the straight plate 4 slides up and down through the outer wall interlayer of the base frame 301 under force, and the bottom of the inner wall of the base frame 301 is rotationally connected to the bottom of the outer wall of the cylinder 302. The bottom of the outer wall of the cylinder 302 is rotated through the bearing at the bottom of the inner wall of the base frame 301 under force, and the inner wall of the cylinder 302 is threadedly connected with a second screw 303, and the top of the second screw 303 is fixedly connected to the bottom of the spindle box 1, and the bottom of the base frame 301 is fixedly connected to the top of the bottom plate 6, and a circular groove 5 is processed at the bottom of the inner wall of the base frame 301.

[0024] Working principle:

[0025] When using the spindle box 1, first make the bottom of the base plate 6 fit with the connection of the light machine tool, then the bolt passes through the circular opening 7 on the top of the base plate 6 and fixes it to the connection to complete the installation of the spindle box 1, then plug the rear of the outer wall of the straight rod 202 with the inner wall of the first straight cylinder 201 to complete the preliminary installation of the second straight cylinder 203, and then use the handle 205 to make the first screw 204 rotate downward through the first straight cylinder 201, so that the bottom of the outer wall of the first screw 204 is plugged with the top circular opening of the straight rod 202 to complete the fixation, and the installation of different components can be changed through the second straight cylinder 203. When the height of the spindle box 1 does not match, the cylinder 302 can be rotated at the bottom of the inner wall of the base frame 301, and the rotating cylinder 302 causes the second screw 303 to move upward, thereby causing the spindle box 1 to move upward to complete the height adjustment to meet the use requirements.

[0026] Embodiment 2:

[0027] See also Figure 1-4 : In this embodiment, a light machine tool spindle box also includes a bent rod 8, a thread 9 and a ring 10. The right side of the bent rod 8 is fixedly connected to the left side of the cylinder 302, the bottom of the outer wall of the bent rod 8 is slidably engaged with the inner wall of the circular groove 5, the outer wall of the bent rod 8 is processed with a thread 9, and the outer wall of the thread 9 is threadedly connected with a ring 10.

[0028] Working principle:

[0029] After the cylinder 302 completes its rotation, the ring 10 rotates downward on the outer wall of the thread 9 so that the bottom of the ring 10 is pressed against the bottom of the inner wall of the base frame 301, and the friction force generated by the ring 10 and the base frame 301 limits the cylinder 302 and achieves fixation.

[0030] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
