Description

Technical Field

[0001] This utility model belongs to the field of drilling and milling machines, and particularly relates to a large-stroke side-cutting drilling and milling machine with a 360-degree rotary table. Background Technology

[0002] Current side-drilling and milling machines primarily employ an XYZ three-axis structure. While a 360-degree rotary table could enable four-sided machining, the three-axis structure limits the travel of the cantilever axis. Therefore, it's impossible to machine all four sides of workpieces with significant length-to-width differences simultaneously. On the two opposite sides of the shorter workpiece, the workpiece is very close to the machine tool. If the 360-degree rotary table is accidentally activated, the longer side of the workpiece could collide with the machine tool, posing a significant safety hazard. Therefore, a three-axis structure equipped with a 360-degree rotary table can only machine workpieces whose length-to-width difference is less than the cantilever axis travel. The full potential of the 360-degree rotary table is not realized, and accidents are highly likely. Consequently, many machine tools do not feature a 360-degree rotary table, even though it is an essential component for industrial automation.

[0003] Existing gantry machine tools can also achieve four-sided machining at one time by adding a rotation function to the lifting axis. However, the requirements for the size of the rotating head are relatively high. Ensuring high rigidity and high machining volume while maintaining volume results in high cost. Moreover, it cannot meet the needs of deep holes. Adding a drill bit several meters long, plus the length of the machine head itself, greatly affects the effective stroke of the gantry beam. Utility Model Content

[0004] This utility model addresses the technical problems existing in the aforementioned drilling and milling machines by proposing a large-stroke side-cutting drilling and milling machine with a 360-degree rotary table, which features a reasonable design, strong processing capability, high safety, and high comprehensive utilization rate.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a large-stroke side-cutting drilling and milling machine with a 360-degree rotary table, including a cantilever shaft, which is slidably mounted on a lifting shaft, and the lifting shaft is slidably mounted on a longitudinal shaft. One or more drive cantilever co-directional shaft slide blocks are provided at the bottom of the longitudinal shaft, and each drive cantilever co-directional shaft slide block is slidably mounted on the drive cantilever co-directional shaft. A power head is provided on the cantilever, and the machining direction of the power head is provided with a 360-degree rotary table.

[0006] Preferably, the bottom of the longitudinal shaft is provided with two drive cantilever co-rotating shaft slides, the drive cantilever co-rotating shaft motor mounts are provided on the drive cantilever co-rotating shaft slides, and the drive cantilever co-rotating shaft motors are provided on the drive cantilever co-rotating shaft motor mounts.

[0007] Preferably, the bottom of the longitudinal shaft is provided with one or more driven cantilever co-rotating shaft slide blocks, which are slidably disposed on the driven cantilever co-rotating shaft.

[0008] Preferably, the bottom of the longitudinal shaft is provided with a drive cantilever co-rotating shaft slide and a driven cantilever co-rotating shaft slide. The drive cantilever co-rotating shaft slide is connected to the drive cantilever co-rotating shaft through a guide rail screw. A drive cantilever co-rotating shaft motor seat is provided on the drive cantilever co-rotating shaft slide, and a drive cantilever co-rotating shaft motor is provided on the drive cantilever co-rotating shaft motor seat. The driven cantilever co-rotating shaft slide is slidably mounted on the driven cantilever co-rotating shaft.

[0009] Preferably, a drive cantilever co-rotating shaft slide is provided at the middle position of the longitudinal axis. The drive cantilever co-rotating shaft slide is connected to the drive cantilever co-rotating shaft through a guide rail screw. A drive cantilever co-rotating shaft motor seat is provided on the drive cantilever co-rotating shaft slide, and a drive cantilever co-rotating shaft motor is provided on the drive cantilever co-rotating shaft motor seat.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] This utility model provides a large-stroke side-cutting drilling and milling machine with a 360-degree rotary table. In addition to the XYZ three-axis structure consisting of the cantilever axis, longitudinal axis, and lifting axis, a new drive cantilever co-directional axis is added. This drive cantilever co-directional axis has an ultra-long stroke to compensate for the short stroke of the cantilever axis inherent in the three-axis structure. When the 360-degree rotary table is working, the machine tool software control must return to a safe position, preventing collisions even when machining workpieces with length and width differences exceeding several meters. This fully utilizes the 360-degree rotary table, enabling fully automated four-sided machining and improving processing efficiency. This utility model features a reasonable design, a large stroke (several meters or even tens of meters), and can perform machining of deep holes and large holes several meters deep. It boasts strong processing capabilities, high safety, and high overall utilization, making it suitable for large-scale promotion. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] The present invention provides embodiments 1-6, in which a base is fixedly connected with a lead screw support rod at equal intervals. The lead screw support rod is equipped with a nut to provide support for the slide. The slide is finely adjusted by adjusting the nut on the lead screw support rod, thereby achieving the flatness of the slide and the overall machining accuracy of the drilling and milling machine.

[0024] Example 1, as Figures 1-2As shown, the present invention provides a large-stroke side-cutting drilling and milling machine with a 360-degree rotary table, including a cantilever shaft 1. The cantilever shaft 1 is slidably mounted on a lifting shaft 2 via a lifting shaft slide 10. The lifting shaft 2 is slidably mounted on a longitudinal shaft 3 via a longitudinal shaft slide 11. Two drive cantilever co-directional shaft slides 6 are provided at the bottom of the longitudinal shaft 3. Each drive cantilever co-directional shaft slide 6 is slidably mounted on a drive cantilever co-directional shaft 4. A power head 7 is provided on the cantilever. The machining direction of the power head 7 is provided with a 360-degree rotary table. The drive cantilever co-rotating shaft slide 6 is provided with a drive cantilever co-rotating shaft motor seat 12, and the drive cantilever co-rotating shaft motor 13 is provided on the drive cantilever co-rotating shaft motor seat 12. The drive cantilever co-rotating shaft motor 13 provides power transmission to the drive cantilever co-rotating shaft 4 and the drive cantilever co-rotating shaft slide 6. The power head 7 is driven by the cantilever shaft 1 and the drive cantilever co-rotating shaft 4 to realize the feed action. With the rotation action of the 360-degree turntable, the equipment can realize four-sided processing. The transmission ends of the lifting shaft 2 and the lifting shaft slide 10, the longitudinal shaft 3 and the longitudinal shaft slide 11, and the drive cantilever co-rotating shaft 4 and the drive cantilever co-rotating shaft slide 6 are all adopted by the screw and slider transmission method. The power part is the motor, which is used to realize the reciprocating linear movement on their respective transmission pairs.

[0025] Specifically, the cantilever shaft 1, lifting shaft 2, and longitudinal shaft 3 constitute a conventional three-axis mechanism. In this structure, the stroke of the cantilever shaft 1 is approximately 1 meter, which limits its length. Increasing the stroke would lead to structural instability, insufficient rigidity, and susceptibility to vertical deformation. Furthermore, the short stroke of the cantilever shaft 1 is insufficient for the large-size 360-degree turntable 5, especially for workpieces with significant length-to-width differences. This embodiment addresses this by installing two drive cantilever shaft slide blocks 6 at the bottom of the longitudinal shaft 3, creating a dual-drive configuration. Dual-drive operation offers better stability. Each drive cantilever shaft slide block 6 is slidably connected to a drive cantilever shaft 4, thus compensating for the short stroke of the cantilever shaft 1. The drive cantilever shaft 4 can be made very long, allowing for machining strokes of several meters or even tens of meters, enabling the machining of deep and large holes several meters in diameter. When the 360-degree rotary table 5 is working, the machine tool software controls the power head 7 to retract to a safe position, preventing collisions even when machining workpieces with length and width differences exceeding several meters. This fully utilizes the capabilities of the 360-degree rotary table 5, enabling fully automated four-sided machining, especially for machining deep and long holes on the sides, thus improving machining efficiency. Therefore, this utility model is reasonably designed, possesses the advantage of a large stroke, capable of machining strokes of several meters or even tens of meters, and can achieve machining of deep and large holes several meters deep. It boasts strong machining capabilities, high safety, and high overall utilization rate.

[0026] Example 2

[0027] The difference from Example 1 is as follows: Figure 3As shown, a drive cantilever co-rotating shaft slide 6 and a driven cantilever co-rotating shaft slide 9 are provided at the bottom of the longitudinal shaft 3. The drive cantilever co-rotating shaft slide 6 is slidably mounted on the drive cantilever co-rotating shaft 4, and the driven cantilever co-rotating shaft slide 9 is slidably mounted on the driven cantilever co-rotating shaft 8. Therefore, the bottom of the longitudinal shaft 3 is a single-drive type, and the auxiliary support is achieved by the sliding cooperation between the driven cantilever co-rotating shaft slide 9 and the driven cantilever co-rotating shaft 8, which improves the stability of the equipment for four-sided side cutting and milling of the workpiece.

[0028] Example 3

[0029] The difference from Example 1 is as follows: Figure 4 As shown, the bottom of the longitudinal shaft 3 consists of two drive cantilever shaft slide blocks 6 in the same direction. Between the drive cantilever shafts 4, there is also a driven cantilever shaft slide block 9. The drive cantilever shaft slide blocks 6 are slidably mounted on the drive cantilever shafts 4, and the driven cantilever shaft slide block 9 is slidably mounted on the driven cantilever shaft 8. Therefore, the bottom of the longitudinal shaft 3 is a dual-drive configuration, which improves the driving performance of the equipment in the cantilever shaft direction. Furthermore, the driven cantilever shaft 8 serves as an auxiliary support structure to prevent the longitudinal shaft 3 from collapsing, thus improving the machining quality of the equipment and ensuring its reasonable design life.

[0030] Example 4

[0031] The difference from Example 1 is as follows: Figure 5 As shown, the bottom of the longitudinal shaft 3 consists of two drive cantilever shaft slide blocks 6 in the same direction. Between the drive cantilever shafts 4, two driven cantilever shaft slide blocks 9 are also arranged at intervals. The drive cantilever shaft slide blocks 6 are slidably mounted on the drive cantilever shafts 4, and the driven cantilever shaft slide blocks 9 are slidably mounted on the driven cantilever shafts 8. Compared to Embodiment 3, this device effectively adds an auxiliary support structure, providing higher support strength to the bottom of the longitudinal shaft 3, improving the anti-collapse beam performance, and allowing the stroke of the longitudinal shaft 3 to be appropriately extended for processing longer sides of the workpiece, further improving the processing capability of this device.

[0032] Example 5

[0033] The difference from Example 1 is as follows: Figure 6As shown, a drive cantilever ram 6 is provided at the bottom of the longitudinal shaft 3. A driven cantilever ram 9 is provided on each side of the drive cantilever ram 6 at intervals. The drive cantilever ram 6 is slidably mounted on the drive cantilever shaft 4, and the driven cantilever ram 9 is slidably mounted on the driven cantilever shaft 8. Therefore, this embodiment is a single-drive configuration. Compared to embodiment 3, the driving force is smaller, but the driving force is installed in the middle position. The longitudinal shaft 3 has an auxiliary support structure on each side of its bottom, which helps control costs and ensures the uniformity of the support force distribution at the bottom of the longitudinal shaft 3.

[0034] Example 6

[0035] The difference from Example 1 is as follows: Figure 7 As shown, the bottom of the longitudinal shaft 3 is a drive cantilever ram 6, and on both sides of the drive cantilever ram 6 are two driven cantilever rams 9 spaced apart from each other, that is, four driven cantilever rams 9. The drive cantilever ram 6 is slidably mounted on the drive cantilever shaft 4, and the driven cantilever rams 9 are slidably mounted on the driven cantilever shaft 8. This embodiment is a single-drive type. Compared with embodiment 5, this device adds two auxiliary support structures, for a total of four sets of auxiliary support structures, which provides higher support strength for the bottom of the longitudinal shaft 3, improves the anti-collapse beam performance, and allows the stroke of the longitudinal shaft 3 to be appropriately extended, further improving the processing capability of this device.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
