Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, specifically to a novel mobile milling, drilling, and boring machine with a tiltable, dual-rotation column. Background Technology

[0002] The milling and drilling machine is a machine tool that integrates the functions of a drilling machine and a milling machine. It can complete multiple processing operations such as drilling, milling, boring, and tapping on one machine tool, reducing the footprint and investment cost of the equipment, while improving production efficiency. It is suitable for processing various small and medium-sized parts. With precision manufacturing process and advanced control system, it can ensure high processing accuracy and surface quality, and can meet the processing needs of some parts with high precision requirements.

[0003] The utility model patent with announcement number CN220112717U discloses a column-tilting five-axis milling and drilling machine. The patent proposes that it "includes a base and a column. The base includes an X-axis lead screw feed device and a Y-axis lead screw feed device that are perpendicular to each other. A guide block is installed in the track groove of the Y-axis lead screw feed device. The two ends of the guide block are symmetrically provided with a left arched track and a right arched track. The bottom of the column is provided with a left arc-shaped track groove and a right arc-shaped track groove corresponding to the left and right arched tracks. The column is fixedly installed on the left and right arched tracks of the guide block in a detachable manner, and the column can tilt to the left or right at a certain angle to facilitate oblique drilling." However, this device has the following problems: the top of the column has a gap, making the structure of the device unstable and susceptible to deformation under cutting forces during processing, which reduces processing quality and equipment life. When processing materials with high hardness, column deformation will lead to increased processing errors. In terms of processing range, for workpieces that need to be processed at lower positions, it is not possible due to the structural limitations at the bottom of the column. Moreover, the sliding track is fixed by screws, which may loosen over time, affecting accuracy. Furthermore, due to the defect in the installation of the left arched track and the column, when components such as racks and drills are installed on the column, the rack cannot continue to move downwards, making it impossible to process lower parts, thus limiting its use.

[0004] For example, announcement number 206981833U discloses a magnetic side-pull rod positioning rotary universal milling machine, which includes a base, an electromagnet below the base, a column above the base, a slider on one side of the column, and a rotary milling head device on the slider. The rotary milling head device includes a side pull rod positioning plate and a milling head on the slider, and the milling head is connected to the slider through the side pull rod positioning plate. This utility model is small in size and easy to carry. It allows for 360° circumferential adjustment of the machining angle, with quick angle positioning. It is also easy to fix and install on steel, simplifying operation. The milling machine is securely mounted, and disassembly and repair are convenient, improving work efficiency. In this patent, one side of the slider 4 has a dovetail mounting block 24 and a rack 25, while the other side has a mounting surface 26. The mounting surface 26 has a positioning protrusion 27 with mounting screw holes 28. As can be seen from the text, the dovetail mounting block 24 and rack 25 are assembled separately. The rack and motor head are connected via a side pull rod positioning plate, resulting in higher costs in processing equipment and assembly. Furthermore, neither of the above two patents can achieve 360° rotation of the column, thus presenting certain defects in use. Therefore, this application proposes another technical solution to address this problem. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a novel mobile milling, drilling, and boring machine with a tiltable, dual-rotation column. This solves the problems of unreasonable column structure design and easy deformation under cutting forces in existing milling and drilling machines, while also addressing the issue of weak connection between the column and components, and allowing the machine head to move lower.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel mobile milling, drilling, and boring machine with a tiltable and dual-rotation column, comprising a base and a column. The front of the column is provided with a rack mounting groove, and the inner walls on the left and right sides of the rack mounting groove are provided with dovetail track grooves. Two track extension blocks are symmetrically installed at the bottom of the dovetail track grooves. The bottom of the rack mounting groove is an open structure, and the top of the rack mounting groove is provided with a connecting sealing plate.

[0007] Preferably, the connecting plate and the column are integrally formed.

[0008] Preferably, the dovetail track groove and the column are integrally formed.

[0009] Preferably, the track extension block extends downward along the column by a distance of 5-15cm.

[0010] Preferably, the track extension block and the column are integrally formed.

[0011] Preferably, a 360° rotation mechanism is also provided between the base and the column.

[0012] Preferably, the 360° rotating mechanism includes an upper rotating mechanism and a lower rotating mechanism. The upper rotating mechanism is provided with an upper dovetail track groove, an upper turntable, and an upper T-bolt insertion hole. The bottom of the upper turntable is provided with a protruding column. The lower rotating mechanism includes a lower turntable and a lower dovetail track groove. The lower turntable is provided with a T-slot and a round hole. The T-slot is provided with a T-bolt insertion hole.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects: This novel movable milling, drilling and boring machine with tiltable double rotation of the column overcomes the shortcomings of traditional screw-fixed steel bars, which are prone to loosening and reduced accuracy due to frequent use and vibration of the equipment, by integrating the dovetail track groove with the column. This makes the two a stable whole, greatly improving the structural stability and reliability. The two symmetrical long track extension blocks added below the column allow the track to slide downward, which is convenient for cutting at lower positions in actual work. It is especially suitable for workpieces that need to be milled and drilled at lower positions, effectively expanding the processing range. The use of connecting sealing plates to seal the top of the column enhances the rigidity of the column, enabling it to better resist external forces such as cutting forces during processing, reducing deformation, and thus improving processing accuracy.

[0027] 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.

[0028] Please see Figures 1 to 13 This embodiment describes a novel mobile milling, drilling, and boring machine with a tiltable, dual-rotation column, comprising a base 1 and a column 2. The column 2 has a rack mounting groove 21 on its front side, and dovetail track grooves 22 on the inner walls of its left and right sides. The dovetail track grooves 22 are integrally formed with the column 2, facilitating more stable and precise sliding. Two track extension blocks 23 are symmetrically installed at the bottom of the dovetail track grooves 22. The track extension blocks 23 are integrally formed with the column 2, extending downwards along the column 2 by 5-15cm, which helps increase the downward movement range and processing area. The bottom of the rack mounting groove 21 is open, and the top of the rack mounting groove 21 is provided with a connecting sealing plate 24, which is integrally formed with the column 2, increasing its strength.

[0029] It should be noted that this new type of mobile milling, drilling, and boring machine with a tiltable, dual-rotation column overcomes the shortcomings of traditional screw-fixed steel bars, which are prone to loosening and reduced accuracy due to frequent use and vibration, by integrating the dovetail track groove 22 with the column 2. This makes the two a stable whole, greatly improving structural stability and reliability. The two symmetrical long track extension blocks 23 added below the column 2 allow the track to slide downwards, making it convenient to cut at lower positions during actual work. This is especially suitable for workpieces that need to be milled and drilled at lower positions, effectively expanding the processing range. The top of the column 2 is sealed with a connecting sealing plate 24, which enhances the rigidity of the column and makes it better able to resist external forces such as cutting forces during processing, reducing deformation and thus improving processing accuracy.

[0030] After improvement, some defects of the existing machine tool were overcome: 1. The dovetail track groove 22 and the column 2 are integrated, avoiding the problem of loosening and reduced accuracy caused by the frequent use and vibration of the existing screw-fixed steel bars. This makes the dovetail track groove 22 and the column 2 a stable whole, greatly improving the stability and reliability of the structure; 2. Two symmetrically distributed track extension blocks 23 are added below the column 2. The length of the track extension blocks 23 is longer than that of the existing technology, allowing the track to slide downwards. This makes it easier to cut at lower positions in actual work, expanding the processing range. It is especially suitable for some workpieces that need to be milled and drilled at lower positions, improving the versatility and processing flexibility of the equipment. The top of the column 2 is sealed with a connecting sealing plate 24, which increases the rigidity of the column 2. During the processing, it can better resist external forces such as cutting forces, reduce the deformation of the column 2, improve the processing accuracy and the stability of the equipment, and ensure the processing quality.

[0031] To facilitate the 360° rotation of the entire column 2, this utility model is further improved by providing a 360° rotation mechanism 3 between the base 1 and the column 2. Figure 3 , Figures 7 to 11 As shown, the 360° rotating mechanism 3 of this utility model includes an upper rotating mechanism 31 and a lower rotating mechanism 32. The upper rotating mechanism 31 is provided with an upper dovetail track groove 311, an upper turntable 312 and an upper T-bolt insertion hole 313. The bottom of the upper turntable 312 is provided with a protruding post 314. The lower rotating mechanism 32 includes a lower turntable 321 and a lower dovetail track groove 322. The lower turntable 321 is provided with a T-slot 323 and a round hole 324. The T-slot is provided with a T-bolt insertion hole 325.

[0032] The installation method is as follows: Specifically, an arc-shaped track 4 is provided between the column 2 and the base 1. For the installation method, please refer to the utility model with announcement number CN220112717U. To facilitate connection with the 360° rotating mechanism 3, a dovetail track 41 of the arc-shaped track is added to the bottom of the arc-shaped track 4. Figure 11 As shown.

[0033] Two T-bolts are inserted into the T-bolt insertion holes 323 of the lower turntable 321. The two T-bolts can slide within the T-slot 323. The principle is described in the patent with publication number 206981833U. Then, the two T-bolts are passed through the upper T-bolt insertion holes 313 respectively. At the same time, the protruding post 314 at the bottom of the upper turntable 312 is inserted into the round hole 324. The T-bolts 2 are locked with nuts. In this way, the upper rotating mechanism 31 and the lower rotating mechanism 32 are assembled together. When the nuts are locked, the upper rotating mechanism 31 and the lower rotating mechanism 32 will not rotate. When the nuts are loosened, the upper rotating mechanism 31 and the lower rotating mechanism 32 can rotate 360 ​​degrees. In order to facilitate reading the degree of rotation of the column 2, a scale is also installed on the upper turntable 312.

[0034] After the upper rotating mechanism 31 and the lower rotating mechanism 32 are installed, the upper dovetail track groove 311 of the upper rotating mechanism 31 is installed with the dovetail track 41 of the arc track, and the lower dovetail track groove 322 of the lower rotating mechanism 32 is installed with the dovetail track of the base 1. Then the electromagnet 5 is installed on the base 1. The locking of the other parts can be done with screws, nuts or by referring to the previously filed patent, so it will not be described in detail.
