Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of machine tool bases, specifically a precision machine tool base with a driving positioning structure. Background Technology
[0002] The machine tool base is an important component of the machine tool. It bears the entire weight of the machine tool and supports other mechanical components such as the column and slide, ensuring the stability and accuracy of the machine tool during the machining process.
[0003] A search revealed that a typical example of an existing machine tool base is disclosed in CN220560893U, which describes an adjustable precision machine tool base. The base includes a lifting assembly at its bottom, with adjustment components installed at each of the four corners of the lifting assembly. Each adjustment component includes a screw mounted at the bottom of the lifting assembly, an adjustment sleeve threaded onto the screw, and a support block fixed to the center of the outer wall of the adjustment sleeve. Multiple support blocks are equipped with extension components. This invention, by setting multiple adjustment components, allows the adjustment sleeve outside the screw to rotate and move downwards in conjunction with the screw, causing the support block connected to the adjustment sleeve to contact a recess in the ground. Alternatively, further adjustment can lift one corner of the base upwards until the base is level. Since the four adjustment components are individually configured, the base can adapt to different ground conditions.
[0004] In summary, existing machine tool bases can only install and fix standard parts when positioning workpieces, and cannot position workpieces of different specifications, resulting in poor performance. Furthermore, they cannot clean up the waste generated inside during continuous processing, and the accumulation can easily affect the use. To address these issues, the existing equipment needs to be improved. Utility Model Content

[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 protection scope of the present utility model.
[0022] Please see Figure 1-4 This utility model provides a technical solution: a precision machine tool base with a driving positioning structure, according to... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a chip collection frame 2 is provided at the bottom of the lower end of the protective frame 1, and self-locking rollers 3 are symmetrically arranged on both sides of the lower end of the chip collection frame 2. The self-locking rollers 3 facilitate the movement of the machine tool base. At the same time, a moving positioning device 5 is provided on the inner side of the upper end of the protective frame 1. The lower end of the moving positioning device 5 forms a lifting structure with the protective frame 1 through symmetrically arranged electric hydraulic cylinders 4. The electric hydraulic cylinders 4 drive the moving positioning device 5 to move down, so that the moving positioning device 5 is located inside the protective frame 1, which makes it convenient to clean up the dust and debris generated during workpiece processing.
[0023] Specifically, the mobile positioning device 5 includes a positioning base 501. The positioning base 501 is slidably connected to the inner side of the protective frame seat 1 via symmetrically arranged guide rails 6 on both sides. A positioning support block 502 is provided in the middle of the upper end of the positioning base 501. The positioning support block 502 facilitates the support of the lower ends of the two placement horizontal seats 508 and also facilitates the positioning of the workpiece. At the same time, electric slide rails 503 are symmetrically arranged on both sides of the upper end of the positioning base 501 about the positioning support block 502. Electric slide blocks 504 are slidably connected to the electric slide rails 503. A support plate 505 is provided on the upper end of the electric slide block 504 near the positioning support block 502. Electric push rods 506 are provided on the support plate 505. The output end of the electric push rod 506 is connected to the corresponding positioning clamping plate 507. The electric push rod 506 pushes the positioning clamping plate 507 to move, which facilitates the adjustment of the position of the positioning clamping plate 507 according to the size of the workpiece, thereby enabling the clamping and positioning of workpieces of different sizes.
[0024] To further explain, a horizontal placement seat 508 is slidably connected to the inner side of the lower end of the support plate 505, and a movable protrusion 509 is provided on the lower end of the side of the horizontal placement seat 508 away from the positioning clamping plate 507. At the same time, the movable protrusion 509 is slidably connected to the groove opened on the inner side of the upper end of the corresponding electric slide seat 504. The upper surface of the horizontal placement seat 508 is at the same level as the lower bottom of the positioning clamping plate 507, and the lower bottom of the horizontal placement seat 508 is at the same level as the upper surface of the positioning support block 502. By moving the horizontal placement seat 508, the movable protrusion 509 at the lower bottom of the horizontal placement seat 508 moves inside the groove, so that the other ends of the two horizontal placement seats 508 are in contact with each other and with the upper end of the positioning support block 502, thereby facilitating the placement of the workpiece.
[0025] according to Figure 1 , Figure 3 and Figure 4 As shown, the lower end of the mobile positioning device 5 is staggered with buffer components between the electric hydraulic cylinders 4. The buffer components include a pressing protrusion 7, a buffer spring 8, and a locking seat 9. The lower end of the pressing protrusion 7 is connected to the locking seat 9 through the buffer spring 8. At the same time, the locking seat 9 is connected to the bottom of the inner end of the protective frame 1 through fixing screws. The outer diameter of the lower bottom of the pressing protrusion 7 is the same as the inner diameter of the upper middle of the locking seat 9. By moving the pressing protrusion 7 downward and pressing the buffer spring 8, the lower bottom of the pressing protrusion 7 is locked with the inner middle of the upper middle of the locking seat 9, so that the positioning base 501 has a certain function during use. It has a certain buffering effect to avoid damage to the protective frame base 1. At the same time, multiple vacuum cleaners 10 are installed on the rear side of the upper end of the protective frame base 1. The rear side of the vacuum cleaners 10 is connected to the rear side of the chip collection bottom frame 2 through the chip discharge pipe 11. The front of the chip collection bottom frame 2 is equipped with a sealing door 201 through a hinge. At the same time, multiple exhaust mesh strips 202 are symmetrically arranged on both sides of the sealing door 201. The dust and debris generated during processing are attracted by the airflow through the vacuum cleaners 10 and transported into the chip discharge pipe 11 to the inside of the chip collection bottom frame 2. The dust and debris are treated in time, ensuring that the processing position is clean and improving the practicality of use.
[0026] In use, the electric slide rail 503 is activated to move the electric slide block 504, which in turn moves the support plate 505, electric push rod 506, and positioning clamping plate 507 to the outer side above the positioning support block 502. This ensures that the distance between the two electric push rods 506 matches the size of the workpiece. Then, the placement crossbeam 508 is pushed so that the two placement crossbeams 508 fit together and are in contact with the upper end of the positioning support block 502. Next, the workpiece is placed in the middle of the upper end of the two placement crossbeams 508. Then, the electric push rod 506 is activated to push the positioning clamping plate 507 to clamp the workpiece. After completion, the electric hydraulic cylinder 4 is activated to move the moving positioning device 5 and the workpiece as a whole downward. At the same time, under the action of the guide slide rail 6, its lifting and lowering movement is highly stable until the downward pressing protrusion 7 at the lower end of the moving positioning device 5 squeezes the buffer spring 8 and engages with the locking seat 9. When processing the workpiece, the vacuum cleaner 10 is activated so that the dust and debris generated during processing are collected inside the chip collection bottom frame 2 through the chip discharge pipe 11.
