[0003] The existing patent document with the publication number CN220128120U provides a multi-mode numerical control machine tool processing tabletop and a numerical control machine tool. In this utility model, first, the round rod is rotated. The round rod drives the first bevel gear to rotate. The first bevel gear drives the second bevel gear to rotate. The second bevel gear drives the rotating rod to rotate. The rotating rod drives the gear to rotate. The gear drives the first rack and the second rack on both sides to move outwards respectively. The first rack and the second rack drive the cross bar to move outwards respectively. Then the cross bar drives the positioning block to move. Subsequently, the workpiece to be processed is placed on the fixed seat. Then the round rod is released. The elastic force of the spring drives the corresponding first rack and second rack to reset, so that the positioning block performs central positioning on the workpiece.

[0004] However, when the existing multi-mode numerical control machine tool processing tabletop is in use, it is not convenient to ensure the stability of the workpiece placement during the processing process.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figure 1 - Figure 4 , the present invention provides a technical solution: A processing table of a multi-mode numerical control machine tool includes a main body mechanism 1 and a protective mechanism 2. The protective mechanism 2 is located below the main body mechanism 1. The main body mechanism 1 includes a main body 101 of the machine tool processing table and a positioning motor 102. The positioning motor 102 is fixedly installed at the right end of the inner end of the main body 101 of the machine tool processing table;

[0026] The main body mechanism 1 further includes a double-sided screw rod 103, a connecting bearing 104, a movable sleeve 105 and a positioning plate 106. The double-sided screw rod 103 is fixedly installed at the transmission end of the left end of the positioning motor 102. The connecting bearing 104 is fixedly installed at the left end of the inner end of the machine tool processing table body 101. The left end of the double-sided screw rod 103 is rotatably connected to the connecting bearing 104. The movable sleeve 105 is threadedly connected to the left and right ends of the outer end of the double-sided screw rod 103. The positioning plate 106 is fixedly installed at the front end of the movable sleeve 105. When using the machine tool processing table body 101 to perform workpiece processing operations, the staff places the workpiece to be processed above the machine tool processing table body 101, and makes the machine tool processing table body 101 located in the middle of the positioning plate 106 and the positioning block 206. The positioning motor 102 works to drive the double-sided screw rod 103 to rotate. The rotation of the double-sided screw rod 103 causes a threaded movement at the connection between the movable sleeve 105 and it. The movable sleeve 105 drives the two groups of positioning plates 106 to move towards the middle, so that the positioning plates 106 are in full contact with the workpiece and position it.

[0027] The protection mechanism 2 includes a rectangular connecting block 201 and a round rod 202. The rectangular connecting block 201 is fixedly installed at the front end of the positioning plate 106, and the round rod 202 is fixedly installed at the inner end of the machine tool working table body 101. The rectangular connecting block 201 is slidably connected to the round rod 202. The protection mechanism 2 further includes side plates 203, which are fixedly installed in the middle of the front and rear ends of the upper end of the machine tool working table body 101. The side plates 203 are located outside the double-sided screw rod 103 and the round rod 202. The protection mechanism 2 further includes an electric push rod 204, which is fixedly installed at the outer end of the side plate 203. The transmission end at the inner end of the electric push rod 204 is located inside the side plate 203. The protection mechanism 2 further includes a push rod 205 and a positioning block 206. The push rod 205 is fixedly installed at the transmission end of the inner end of the electric push rod 204, and the positioning block 206 is fixedly installed at the inner end of the push rod 205. The protection mechanism 2 further includes a base 207 and a shock absorber 208. The base 207 is located below the machine tool working table body 101, and the shock absorber 208 is fixedly installed at the upper end of the base 207. The upper end of the shock absorber 208 is fixedly connected to the machine tool working table body 101. The protection mechanism 2 further includes a support sleeve 209 and a support rod 210. The support sleeve 209 is fixedly installed at the lower end of the machine tool working table body 101, and the support rod 210 is fixedly installed at the upper end of the base 207. The support rod 210 is movably connected to the support sleeve 209. When the electric push rod 204 works, it pushes the positioning block 206 to fully contact the workpiece, further reinforcing it, so that the workpiece is stably placed at the center above the machine tool working table body 101, and then the processing operation of the workpiece can be carried out. During the processing of the workpiece, the machine tool working table body 101 moves downward under force, causing the support sleeve 209 to slide outside the support rod 210. The shock absorber 208 buffers the impact force received by the machine tool working table body 101, reduces the shaking and wear brought to the processed workpiece, and ensures its stability during the processing process.

[0028] Working principle: When using the machine tool processing table body 101 to perform workpiece processing operations, the staff place the workpiece to be processed above the machine tool processing table body 101, and make the machine tool processing table body 101 located in the middle of the positioning plate 106 and the positioning block 206. The positioning motor 102 works to drive the double-sided screw rod 103 to rotate. The rotation of the double-sided screw rod 103 causes a threaded movement at the connection between the movable sleeve 105 and it. The movable sleeve 105 drives the two groups of positioning plates 106 to move towards the middle. The positioning plate 106 drives the rectangular connecting block 201 to slide on the round rod 202, so that the positioning plate 106 is in full contact with the workpiece to position it. Then, the electric push rod 204 is started to push the positioning block 206 to be in full contact with the workpiece to further reinforce it, so that the workpiece is stably placed at the center above the machine tool processing table body 101, and then the workpiece processing operation can be carried out. During the processing of the workpiece, the machine tool processing table body 101 moves downward under force, causing the support sleeve 209 to slide outside the support rod 210. The shock absorber 208 buffers the impact force received by the machine tool processing table body 101, reduces the shaking and wear brought to the processed workpiece, and ensures its stability during the processing process.

[0029] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than a limitation on the protection scope of the present invention. Any simple modification or equivalent replacement of the technical solution of the present invention by those of ordinary skill in the art shall not depart from the essence and scope of the technical solution of the present invention.
