Description

Technical Field

[0001] This utility model relates to the field of CNC milling machine technology, and in particular to a double gantry CNC milling machine for producing automotive parts. Background Technology

[0002] In the current booming automotive industry, the manufacturing precision and production efficiency of auto parts have become key factors determining the overall quality and market competitiveness of automobiles. As a core piece of equipment in auto parts processing, the technological evolution and application of double-gantry CNC milling machines have attracted much attention. Traditional auto parts processing equipment has many limitations in terms of precision and efficiency. Early ordinary milling machines relied on manual operation, and the processing precision was greatly affected by the operator's skill level, making it difficult to meet the increasingly stringent tolerance standards for auto parts. For example, key components such as engine blocks and transmission gears, with their complex structures and high precision requirements, have a high scrap rate when processed using traditional equipment. At the same time, manual operation is slow and has long production cycles, making it unsuitable for the pace of large-scale production in the automotive industry.

[0003] The existing patent publication number CN204912872U discloses a dual-drive gantry CNC milling machine, including a worktable, a gantry frame, and a machining device. The worktable includes a worktable body and a T-slot on the worktable body. The gantry frame includes a first support column, a second support column, and a crossbeam. The crossbeam is connected to the first and second support columns respectively via a first synchronous sliding device and a second synchronous sliding device. The first and second support columns are fixed to the left and right sides of the worktable body, respectively. The machining device includes a first Z-axis device and a second Z-axis device. The first Z-axis device is connected to the crossbeam via a first sliding device, and the second Z-axis device is connected to the crossbeam via a second sliding device. This utility model optimizes the structure of the CNC milling machine based on the existing technology, enabling two or more spindles to perform simultaneous machining on a single gantry frame. This significantly improves the working efficiency of the milling machine while saving the workspace occupied by the milling machine and reducing production costs.

[0004] Existing double-gantry CNC milling machines for automotive parts production generate vibrations during operation, resulting in significant noise that disrupts the workshop environment and may damage the hearing of operators. Therefore, we propose a new double-gantry CNC milling machine for automotive parts production to address these issues. Utility Model Content

[0029] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0030] Example 1, refer to Figure 1-5 In this embodiment, in order to solve the problem of excessive vibration and noise generated during the operation of existing double-gantry CNC milling machines for automotive parts production, this utility model discloses a double-gantry CNC milling machine for automotive parts production.

[0031] It includes a milling machine body 1, and a noise reduction structure 2 is fixedly connected to the lower side of the milling machine body 1;

[0032] The noise reduction structure 2 includes a fixed plate 201, which is fixedly connected to the lower side of the milling machine body 1. A shock-absorbing main column 202 is fixedly connected to the lower side of the fixed plate 201. A connecting frame column 203 is movably connected to the lower side of the shock-absorbing main column 202. An air pressure column 204 is fixedly connected to the lower side of the connecting frame column 203.

[0033] The connecting frame column 203 and the air pressure column 204 are integrated into one unit, and the shock-absorbing main column 202 is movably connected to the inner cavity of the air pressure column 204;

[0034] Specifically, when the milling machine body 1 vibrates, the damping main column 202 can transmit the vibration to the connecting frame column 203. Since the damping main column 202 is movably connected to the inner cavity of the pneumatic column 204, the gas in the pneumatic column 204 can buffer the vibration and reduce the transmission of the vibration. The pneumatic column 204 fixed on the lower side of the connecting frame column 203 will further disperse and buffer the vibration.

[0035] A connecting frame column 203 is fixedly connected to the lower side of the pneumatic column 204, and a sliding support column 206 is fixedly connected to one side of the connecting frame column 203.

[0036] The sliding support column 206 is fixedly connected to one side of the connecting frame column 1 203 and the connecting frame column 205. The sliding support column 206 is symmetrically arranged on both sides of the connecting frame column 205. The inner side of the sliding support column 206 is provided with a groove.

[0037] Specifically, the sliding support column 206 on one side of the connecting frame column 1 203 is symmetrically arranged on both sides of the connecting frame column 205. Its inner groove can provide guidance and a certain buffering effect for the movement of the connecting frame column 205, making the connecting frame column 205 more stable when vibrating.

[0038] The lower side of the connecting frame column 205 is movably connected to the shock-absorbing main column 207, the lower side of the shock-absorbing main column 207 is fixedly connected to the bottom column 208, and the lower side of the bottom column 208 is fixedly connected to the bottom plate 209.

[0039] Specifically, the shock-absorbing main column 207 on the lower side of the connecting frame column 205 will transmit the vibration to the bottom column 208 when it is subjected to vibration. The bottom plate 209 on the lower side of the bottom column 208 contacts the ground to further absorb and disperse the vibration, thereby reducing the vibration amplitude of the entire milling machine and reducing noise generation.

[0040] A connecting post 210 is fixedly connected to the lower side of the fixed plate 201. A connecting shaft 211 is movably connected to the inner side of the connecting post 210. A connecting rod 212 is movably connected to the outer side of the connecting shaft 211. A connecting shaft 213 is movably connected to the inner side of the connecting rod 212.

[0041] A sliding block 214 is fixedly connected to one side of the connecting shaft 213, a connecting rod 215 is movably connected to the outside of the connecting shaft 213, a connecting shaft 3 216 is movably connected to one end of the connecting rod 215, and a connecting column 217 is movably connected to the outside of the connecting shaft 3 216.

[0042] Connecting column 217 is connected to base plate 209 via bottom column 208;

[0043] Specifically, the structure consisting of connecting post 210, connecting shaft 211, connecting rod 212, connecting shaft 213, sliding block 214, connecting rod 215, connecting shaft 3, and connecting post 217 on the lower side of the fixed plate 201 will decompose and buffer the vibration through the movable connection between the components when the milling machine vibrates.

[0044] The specific working principle is as follows: The milling machine generates vibration during operation, and the fixed plate 201 transmits the vibration to the damping main column 202. The damping main column 202 moves within the pneumatic column 204, which buffers the vibration with internal gas. The connecting frame column 203 is integrated with the pneumatic column 204, and the vibration continues to be transmitted downwards. The sliding support column 206 guides the connecting frame column 205 and dissipates the vibration energy through its groove. The damping main column 207, the bottom column 208, and the bottom plate 209 under the connecting frame column 205 further buffer and disperse the vibration. The linkage structure composed of the connecting column 210, connecting rods, etc., moves during vibration, changing the direction and magnitude of vibration transmission, consuming vibration energy, and achieving vibration reduction and noise reduction.

[0045] Example 2, refer to Figure 1-5 In this embodiment, in order to solve the problem of iron filings generated by existing double-gantry CNC milling machines for automotive parts production affecting the work process, based on the same concept as in Embodiment 1 above, this double-gantry CNC milling machine for automotive parts production also includes a noise reduction structure 2:

[0046] A flushing structure 3 is fixedly connected to the lower side of the milling machine body 1. The flushing structure 3 includes an operating table 301. The operating table 301 is fixedly set on the lower side of the milling machine body 1. A movable slot 302 is opened on the inner side of the operating table 301. A motor 303 is fixedly connected to one side of the operating table 301. A stud 304 is movably connected to one side of the motor 303.

[0047] The stud 304 is movably disposed inside the movable slot 302, and a driving body is disposed on the outside of the stud 304;

[0048] Specifically, the motor 303 is fixed on one side of the operating table 301. When the motor 303 is started, it will drive the stud 304, which is movably connected to it, to rotate in the movable slot 302.

[0049] A flushing base plate 305 is movably provided on the upper side of the stud 304. A connecting seat 306 is fixedly connected to the upper side of the flushing base plate 305. A water inlet 307 is fixedly connected to one side of the connecting seat 306. A flushing pipe 308 is fixedly connected to the inner side of the connecting seat 306.

[0050] Stud 304 is connected to flushing base plate 305 via drive body;

[0051] Specifically, the driving body on the outside of the stud 304 will move linearly along the stud 304 when the stud 304 rotates. Since the stud 304 is connected to the flushing base plate 305 through the driving body, the linear movement of the driving body will cause the flushing base plate 305 to move linearly on the upper side of the stud 304.

[0052] The specific working principle is as follows: Motor 303 is energized and starts, driving stud 304 to rotate within the movable slot 302. The driving body on the outside of stud 304 is threadedly engaged with it. According to the principle of threaded transmission, the driving body converts the rotation of stud 304 into linear motion. The driving body is connected to the flushing base plate 305, causing the flushing base plate 305 to reciprocate linearly above stud 304. Water is supplied through inlet 307, and the cleaning fluid flows into connecting seat 306 and then into flushing pipe 308. As the flushing base plate 305 moves, the flushing pipe 308 moves accordingly, spraying cleaning fluid onto the milling machine's machining area to wash away debris, oil, and other impurities generated during machining, ensuring a clean machining environment and preventing impurities from affecting machining accuracy and the normal operation of the milling machine.

[0053] The wiring diagrams of the motor and cylinder in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the motor and cylinder will not be explained in detail.

[0054] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
