[0022] 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 protection scope of the present utility model.

[0023] Please see Figure 1-6This utility model provides a floor-type milling and boring machine capable of limiting workpieces of different sizes. It includes a bed 1, with a movable seat 2 on one side of the top of the bed 1. The movement of the movable seat 2 drives the machining table 3 to move horizontally. The movable seat 2 has a rotating mechanism inside, which drives the machining table 3 to rotate for machining. The machining table 3 is located at the top of the movable seat 2. A lead screw 4 is rotatably mounted inside the machining table 3. Both ends of the lead screw 4 are threadedly connected to sliding plates 5 via lead screw nuts. Rotation of the lead screw 4 allows the two sliding plates 5 to adjust towards each other along the surface of the lead screw 4. Combined with the column 6, the position of the slide rod 7 and the clamping plate 8 can be adjusted. The position of the clamping plate 8 can be adjusted according to the size requirements of the workpiece. The slide plate 5 is fixed with columns 6 on both sides. The top of the column 6 is slidably equipped with the slide rod 7. One end of the slide rod 7 is fixed with the clamping plate 8. A square box 9 is fixed on one side of the column 6. The inside of the square box 9 is equipped with a moving component 11 for moving the slide rod 7. The moving component 11 can drive the slide rod 7 to move and adjust. One end of the lead screw 4 is equipped with a rotating component 12. The rotating component 12 can drive the lead screw 4 to rotate in the forward or reverse direction.

[0024] The moving assembly 11 includes a fixed plate 1101, which is fixedly installed in the middle of the inside of the square box 9. A threaded rod 1102 is threadedly connected to the middle of the fixed plate 1101. A moving block 10 is rotatably provided at one end of the threaded rod 1102. One side of the moving block 10 is fixedly connected to the other end of the slide rod 7. The moving block 10 is slidably connected to the inner wall of the square box 9. Four evenly spaced guide rods 1103 are slidably provided on the surface of the fixed plate 1101. One end of the guide rod 1103 is fixedly connected to the other side of the moving block 10. A rotating rod 1104 is fixedly provided at the other end of the threaded rod 1102. A rotating handle 1105 is fixedly provided at one end of the rotating rod 1104. Through the moving assembly 11, the rotating handle 1105 drives the threaded rod 1102 to rotate. Combined with the guide rods 1103, the moving block 10 and the slide rod 7 move in the horizontal direction.

[0025] The rotating assembly 12 includes a support rod 1201, which is fixedly installed at one end of the lead screw 4. A housing 1202 is fixedly installed in the middle of one side of the processing table 3. One end of the support rod 1201 passes through the processing table 3 and is rotatably connected to the inner wall of the housing 1202. A worm gear 1203 is fixedly installed in the middle of the support rod 1201. A worm 1204 is meshed with one side of the worm gear 1203. The bottom end of the worm 1204 is fixedly connected to the bottom end of the inner wall of the housing 1202. The top of the worm gear 1204 is fixedly mounted on the box body 1202 and a second throttle 1205 is fixed thereon. The worm gear 1204 is rotated and adjusted by the rotating component 12 and the second throttle 1205. The worm gear 1203 is meshed and connected, which in turn drives the worm gear 1203 to rotate. Due to the rotation of the worm gear 1203, this linkage mechanism can drive the lead screw 4 to be adjusted in the forward or reverse direction, and can also play a self-locking role on the lead screw 4 to effectively prevent it from rotating.

[0026] The threads at both ends of the lead screw 4 turn in opposite directions. The inner wall of the clamping plate 8 is fixedly provided with an anti-slip pad, and the anti-slip pad is made of rubber. Two limiting plates 13 are symmetrically slidable between the two sliding plates 5. The bottom end of the limiting plate 13 is fixedly connected to the inner wall of the processing table 3. Since the threads at both ends of the lead screw 4 turn in opposite directions, the two sliding plates 5 are driven to adjust synchronously in opposite directions during the rotation of the lead screw 4. The anti-slip pad is made of rubber, which can play an anti-slip protection role during the workpiece clamping process. The limiting plate 13 can limit and guide the movement of the two sliding plates 5, effectively ensuring that the two sliding plates 5 are adjusted synchronously in opposite directions.

[0027] A spindle box 15 is slidably provided on the other side of the top of the bed 1, and a cutting tool 16 for machining the workpiece is provided in the middle of one side of the spindle box 15. Support plates are fixed on both sides of the bottom of the bed 1. The spindle box 15 and the cutting tool 16 provided thereon are existing known equipment that can perform machining operations on the workpiece.

[0028] A guide plate 14 is fixedly provided on the top of one side of the clamping plate 8. One end of the guide plate 14 passes through the column 6 and extends to one side of the column 6. The guide plate 14 can limit and guide the movement of the clamping plate 8 and ensure the stability of the clamping plate 8 during movement.

[0029] When using this device, first, place the part to be processed securely on top of the processing table 3. Then, adjust the positions of the four clamping plates 8 according to the size and specifications of the part. Specifically, by turning the throttle 1205, the worm gear 1204 is rotated. The rotation of the worm gear 1204 drives the worm wheel 1203, which meshes with it, to rotate synchronously. With the help of this linkage mechanism, the lead screw 4 can be adjusted in the forward or reverse direction. It is worth mentioning that this design also has a self-locking function, which can effectively prevent the lead screw 4 from rotating accidentally after adjustment. Since the threads at both ends of the lead screw 4 turn in opposite directions, when the lead screw 4 rotates, the two sliding plates 5... The relative movement controls the distance between the four columns 6. After the position adjustment is completed, the threaded rod 1102 is rotated by turning the throttle 1105. Under the synergistic effect of the guide rod 1103, the moving block 10 and the slide rod 7 move smoothly in the horizontal direction, so that the four clamping plates 8 are tightly attached to the four corners of the workpiece to be processed and squeezed against each other, thus achieving a stable clamping of the workpiece. In this process, reliable limiting and fixing of workpieces of different sizes can be achieved, greatly reducing the limitations in the processing process. Finally, the clamped and fixed parts can be precisely processed by controlling the spindle box 15 and the cutting tool 16.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
