[0002] Machine tools refer to devices for manufacturing machines and machinery, also known as mother machines or machine tools, and are usually referred to as machine tools. All parts with high precision requirements and fine surface roughness requirements generally need to be finally processed on machine tools using cutting methods. Machine tools play a major role in the construction of national economic modernization. With the development of the economy, machine tool production lines need to be moved and fixed again during factory relocation or reconstruction.

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] Reference Figure 1-Figure 3, a fixed structure of a machine tool production line assembly platform, comprising a housing 1, a bottom plate 2 is fixedly connected to the housing 1, and a stabilizing mechanism is arranged on the bottom plate 2;

[0023] The stabilizing mechanism comprises a limiting column 4, a rack plate 5, a gear 6, a bidirectional screw rod 7, a nut seat 8, and a connecting block 9. A plurality of through holes are provided on the bottom plate 2, and a plurality of limiting columns 4 are slidably connected in the through holes. A plurality of rack plates 5 are fixedly connected to the side walls of the limiting columns 4, the bidirectional screw rod 7 is rotatably connected to the side wall of the housing 1, the gear 6 is fixedly connected to the bidirectional screw rod 7, the nut seat 8 is threadedly connected to the bidirectional screw rod 7, and the connecting block 9 is fixedly connected to the nut seat 8. A plurality of sliding grooves are provided on the bottom plate 2, and the connecting block 9 is slidably connected in the sliding groove. The limiting column 4 slides to drive the rack plate 5 to move, and the rack plate 5 moves to drive the gear 6 to move. The gear 6 moves to drive the bidirectional screw rod 7 to rotate, and the bidirectional screw rod 7 rotates the nut seat 8 to slide. The threads of the bidirectional screw rod 7 at both ends of the gear 6 are in opposite directions. When the limiting column 4 drives the gear 6 to move downward, the bidirectional screw rod 7 drives the two nut seats 8 to move in the direction close to the gear 6, and the two nut seats 8 drive the connecting block 9 to approach each other.

[0024] The stabilizing mechanism also includes a push plate 10, a push rod 11, and a buffer spring 12. The push rod 11 is slidably connected to the connecting block 9, the push plate 10 is fixedly connected to the side wall of the push rod 11, the buffer spring 12 is fixedly connected between the push plate 10 and the connecting block 9, and the buffer spring 12 is sleeved on the outer surface of the push rod 11. The connecting blocks 9 are close to each other, driving the push rods 11 to be close to each other, and driving the push plates 10 to be close to each other, thereby pushing and clamping the machine tool to make it slide toward the center. The buffer spring 12 can provide a certain clamping force and provide a certain buffer space so that it can clamp machine tools of different widths.

[0025] The upper end surfaces of the plurality of limit columns 4 are fixedly connected with a damping plate 3 , on which a plurality of positioning holes are provided. When in use, the machine tool is placed on the damping plate 3 , and the damping plate 3 moves downward to drive the limit columns 4 to move.

[0026] The side wall of the shock absorbing plate 3 is slidably connected with a positioning plate 13, and the side wall of the positioning plate 13 is fixedly connected with multiple positioning wheels 14. When in use, the machine tool is lifted by a sling, and the positioning plate 13 is fixed to the lower end surface of the machine tool by bolts, and then the positioning plate 13 is placed on the shock absorbing plate 3. The positioning wheels 14 enable the positioning plate 13 to slide on the shock absorbing plate 3.

[0027] A limit block is provided on the side wall of the push rod 11, which limits the push rod 11 to prevent it from being separated from the connecting block 9. The side wall hinge of the shell 1 is connected with a partition door. After the machine tool is placed, the partition door is opened and the limit column 4 is fixed by bolts to keep it stable.

[0028] A plurality of shock absorbing springs 15 are fixedly connected between the shock absorbing plate 3 and the base plate 2. The shock absorbing springs 15 are sleeved on the outer surface of the limit column 4. The shock absorbing springs 15 provide buffering when the shock absorbing plate 3 descends to prevent the machine tool from being damaged by hard contact with the ground.

[0029] In the utility model, when in use, first use a sling to lift the shell of the machine tool production line, install the positioning plate 13 to the bottom of the shell by bolts, and then put it on the shock-absorbing plate 3. The shock-absorbing plate 3 descends and drives the limit column 4 to descend. The shock-absorbing spring 15 provides a buffer when the shock-absorbing plate 3 descends to avoid damage caused by hard contact with the machine tool on the ground. The limit column 4 descends and drives the gear 6 to move downward, driving the two-way screw rod 7 to move so that the two nut seats 8 move in the direction close to the gear 6. The two nut seats 8 drive the connecting blocks 9 to approach each other. The connecting blocks 9 approach each other and drive the push rod 11 to approach each other, driving the push plate 1 0 are close to each other, thereby pushing and clamping the machine tool to slide toward the center of the shock-absorbing plate 3. When the positioning wheel 14 on the positioning plate 13 slides into the positioning hole, the machine tool has been placed in the center of the shock-absorbing plate 3. After the machine tool production line assembly platform is placed, the partition door is opened and the limit column 4 is fixed by bolts to keep it stable, so that the machine tool production line assembly platform automatically moves toward the center when placed, avoiding tipping to one side due to alignment with the center line during placement, causing damage to the machine tool production line assembly platform. The contents not described in detail in this description belong to the prior art known to professional and technical personnel in this field.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
