Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, specifically a milling, drilling, and boring integrated machine with a column and spindle that can rotate 360 ​​degrees. Background Technology

[0002] Milling machines are essential general-purpose equipment in the machinery manufacturing industry and are the second most produced machine tool after lathes. A milling machine is a machine tool that uses a milling cutter to machine various surfaces of a workpiece. Typically, the milling cutter's rotation is the primary motion, while the movement of the workpiece and the cutter constitutes the feed motion. It can machine planes, grooves, various curved surfaces, gears, and more. Furthermore, in addition to milling planes, grooves, gear teeth, threads, and splined shafts, milling machines can also machine relatively complex profiles, making them widely used in machinery manufacturing and repair departments.

[0003] The prior art, CN206981833U, discloses a magnetic side-pull rod positioning rotary universal milling machine. It includes a base, an electromagnet below the base, a column above the base, and a slider on one side of the column. A rotary milling head device is mounted on the slider, comprising a side-pull rod positioning plate and a milling head, which are connected to the slider via the side-pull rod positioning plate. This device is small and portable, allowing for 360° circumferential adjustment of the machining angle with fast positioning. It is also easy to fix on steel, simplifying operation. The milling machine is securely installed, easy to disassemble, and convenient for maintenance and replacement, improving work efficiency. However, during use, a 30-Y axis lead screw feed device is added between the column and the base, resembling a sliding plate, increasing cost. Furthermore, the short track design between the column and the base limits the range of motion. Additionally, neither the column nor the spindle can rotate, which may not meet the requirements in certain applications, causing inconvenience.

[0004] For example, utility model patent with announcement number 206981833U discloses a magnetic side tie 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 tie rod positioning plate and a milling head on the slider, and the milling head is connected to the slider through the side tie rod positioning plate. This utility model is small in size and easy to carry. It allows for 360° circumferential adjustment of the machining angle, enabling quick angle positioning. It is also easy to fix and install on steel, simplifying operation. The milling machine is securely mounted, easy to disassemble, and convenient for maintenance and replacement, thus improving work efficiency. However, 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, with the rack and motor head connected via a side tie rod positioning plate, resulting in significant costs in processing equipment and assembly. Therefore, a milling, drilling, and boring integrated machine with a column and spindle capable of 360° rotation is proposed to solve the aforementioned problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides an integrated milling, drilling, and boring machine with a column and spindle that can rotate 360 ​​degrees, which has advantages such as easy adjustment and solves the problems in existing technologies.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a milling, drilling, and boring machine with a column and spindle that can rotate 360 ​​degrees, comprising a column, a base, a motor, and a spindle box. The column is equipped with a gear rod and a dovetail track groove. A rack is fitted into the dovetail track groove, and the rack meshes with the gear rod. A universal rotation adjustment mechanism is provided between the rack and the spindle box, allowing the spindle box to rotate 360° in both directions. A 360° rotation adjustment mechanism is provided between the column and the base, allowing the column to rotate 360° in both directions.

[0007] Preferably, the universal rotation adjustment mechanism includes an adapter plate disposed on the rack, a connecting plate disposed on the spindle box, a T-trapezoidal bolt, and a locking nut; the adapter plate is provided with a T-bolt through hole and a T-slot, the shape of the T-slot matching the shape of the T-bolt, and the T-trapezoidal bolt can rotate in the T-slot after entering the T-slot through the T-bolt through hole; the connecting plate is provided with a through hole, and the T-trapezoidal bolt placed in the T-slot passes through the through hole and is locked by the locking nut.

[0008] Preferably, the rack and the adapter plate are integrally formed; the spindle box and the connecting plate are integrally formed.

[0009] Preferably, there are two T-trapezoidal bolts and two locking nuts.

[0010] Preferably, the 360° rotation adjustment mechanism includes an upper rotation mechanism and a lower rotation mechanism. The upper rotation 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 rotation mechanism includes a lower turntable and a lower dovetail track groove. The lower turntable is provided with a lower T-slot and a lower circular hole. The lower T-slot is provided with a lower T-bolt insertion hole. The upper dovetail track groove cooperates with the dovetail track opened at the bottom of the column.

[0011] Preferably, the connecting plate and the upper turntable are each fitted with a graduated dial.

[0012] Preferably, an electromagnet is also provided below the base.

[0013] Compared with the prior art, the milling, drilling, and boring integrated machine of this utility model, in which the column and spindle can rotate 360 ​​degrees, has the following beneficial effects:

[0014] This integrated milling, drilling, and boring machine, with a column and spindle capable of 360-degree rotation, eliminates the need for the original 30-Y axis lead screw feed device by directly opening a dovetail slide on the column base, allowing it to cooperate with the slider installed below the column, thus achieving cost reduction and efficiency improvement. The connection between the rack and spindle, compared to the original side tie rod connection, also achieves cost reduction and efficiency improvement. In addition, this invention adds two rotation adjustment mechanisms, allowing both the column and spindle to be adjusted 360° in both directions, improving the flexibility of use and meeting the needs of different scenarios.

[0024] 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.

[0025] Please see Figures 1 to 9 This embodiment discloses a milling, drilling, and boring machine with a column and spindle that can rotate 360 ​​degrees. It includes a column 1, a base 2, a motor 3, and a spindle box 4. The column 1 is equipped with a gear rod 11 and a dovetail track groove 12. A rack 5 is fitted into the dovetail track groove 12, and the rack 5 meshes with the gear rod 11. The machine is characterized by a universal rotation adjustment mechanism 6 between the rack 5 and the spindle box 4, allowing the spindle box 4 to rotate 360° in both directions. A 360° rotation adjustment mechanism 7 is also provided between the column 1 and the base 2, allowing the column 1 to rotate 360° in both directions.

[0026] like Figure 2 , Figure 4 and Figure 5As shown, the universal rotary adjustment mechanism 6 of this utility model includes a transfer plate 61 mounted on a rack 5, a connecting plate 62 mounted on a spindle box 4, a T-trapezoidal bolt 63, and a locking nut 64. The transfer plate 61 has a T-bolt through hole 65 and a T-slot 66. The shape of the T-slot 66 matches the shape of the T-bolt. The T-trapezoidal bolt 63 can rotate within the T-slot 66 after entering through the T-bolt through hole 65. The connecting plate 62 has a through hole 67. The T-trapezoidal bolt 63 placed in the T-slot 66 passes through the through hole 67 and is locked by the locking nut 64. Preferably, the utility model has two T-trapezoidal bolts 63 and two locking nuts 64. The rack 5 and the transfer plate 61 are integrally formed. The spindle box 4 and the connecting plate 62 are integrally formed. In this utility model, the principle by which the spindle box 4 can rotate 360° in both directions through the adjustment of the universal rotation adjustment mechanism 6 is as follows: When the locking nut 64 is tightened, the connecting plate 62 on the spindle box 4 and the adapter plate 61 on the rack 5 will fit tightly together and will not rotate. When the locking nut 64 is loosened, the two will not fit together. Since the T-trapezoidal bolt 63 can rotate in the T-groove 66 after entering the T-groove 66 through the T-bolt through hole 65, the spindle box 4 can rotate 360° in both directions. This principle is similar to the side tie rod positioning plate principle of the utility model patent with announcement number 206981833U.

[0027] like Figure 2 , Figures 6 to 9 As shown, the 360° rotation adjustment mechanism 7 of this utility model includes an upper rotation mechanism 71 and a lower rotation mechanism 72. The upper rotation mechanism 71 is provided with an upper dovetail track groove 711, an upper turntable 712 and an upper T-bolt insertion hole 713. The bottom of the upper turntable 712 is provided with a protruding column 714. The lower rotation mechanism 72 includes a lower turntable 721 and a lower dovetail track groove 722. The lower turntable 721 is provided with a lower T-shaped groove 723 and a lower round hole 724. The lower T-shaped groove 723 is provided with a lower T-bolt insertion hole 725. The upper dovetail track groove 711 cooperates with the dovetail track 13 opened at the bottom of the column 1.

[0028] The procedure is as follows: Take two T-bolts and insert them into the lower T-slot 723 of the lower turntable 721. The two T-bolts can slide within the lower T-slot 723. The principle is described in the patent with publication number 206981833U. Then, pass the two T-bolts through the upper T-bolt insertion hole 713 respectively. At the same time, insert the protruding post 714 at the bottom of the upper turntable 712 into the round hole 724. T-bolts 2 are locked with nuts. In this way, the upper rotating mechanism 71 and the lower rotating mechanism 72 are assembled together. When the nuts are locked, the upper rotating mechanism 71 and the lower rotating mechanism 72 will not rotate. When the nuts are loosened, the upper rotating mechanism 71 and the lower rotating mechanism 72 can rotate 360 ​​degrees. In order to facilitate reading the degree of rotation of the column 1 and the spindle box 4, scales are also installed on the connecting plate 62 and the upper turntable 712 respectively.

[0029] After the upper rotating mechanism 71 and the lower rotating mechanism 72 are installed, as follows Figure 3 As shown, the upper dovetail track groove 711 of the upper rotating mechanism 71 is installed with the dovetail track 13 opened at the bottom of the column 1, and the lower dovetail track groove 722 of the lower rotating mechanism 72 is installed with the dovetail track of the base 2. Then the electromagnet 8 is installed on the base 2. 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.

[0030] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical methods, and can be implemented as long as they can achieve their beneficial effects. It should be noted that the orientation or positional relationship indicated herein is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
