Description

Technical Field

[0001] This utility model relates to the field of machining center technology, and in particular to a gantry machining center with a noise reduction structure. Background Technology

[0002] Machining centers evolved from CNC milling machines. The biggest difference between them and CNC milling machines is that machining centers have the ability to automatically change machining tools. By installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed in a single setup via an automatic tool changer, realizing multiple machining functions. CNC machining centers are high-efficiency automated machine tools suitable for machining complex parts, consisting of mechanical equipment and a CNC system.

[0003] CN220074096U discloses a gantry machining center with a noise reduction structure, including a frame. The frame has sliding grooves on both sides of its exterior. A protective shell is slidably mounted on the exterior of the frame through the two sliding grooves. Positioning plates are fixed on both sides of the frame. Angle shafts are fixed on both sides of the front surface of the two positioning plates. A support plate is rotatably mounted on the front surface of each positioning plate through the two angle shafts.

[0004] Although the device uses a sliding protective shell to isolate the interior of the frame and prevent excessive noise transmission, and can be fixed to the ground with support plates during frame installation, the two support plates provide diagonal support to both sides of the frame to increase the overall stability of the frame and prevent the frame from shaking and generating noise during use, the mechanical structure operation of the gantry machining center during use will cause the device to vibrate and generate noise. Fixing the device may cause structural vibration to accelerate structural wear and generate noise. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a gantry machining center with a noise reduction structure.

[0006] This utility model is achieved by the following technical solution: a gantry machining center with a noise reduction structure, including a base, a main body on the top of the base, a noise reduction mechanism on the top of the base, and a machining mechanism on the surface of the main body;

[0007] The noise reduction mechanism includes a support block, a damper fixedly connected to the surface of the support block, a buffer groove on the top of the base, a slider slidably connected to the inner wall of the buffer groove, a spring damping block fixedly connected to the top of the slider, a fixing block fixedly connected to the top of the spring damping block, a protective shell fixedly connected to the top of the main body, sound-absorbing cotton fixedly connected to the inner wall of the protective shell, an inner shell fixedly connected to the side of the sound-absorbing cotton away from the protective shell, a sound-insulating groove on the top of the main body, a sliding cover slidably connected to the inner wall of the sound-insulating groove, and a handle fixedly connected to the surface of the sliding cover.

[0008] The above technical solution, by setting sound-absorbing cotton between the outer and inner shells, creates a multi-layered structure that absorbs noise during use, isolating the noise inside the device and improving its practicality.

[0009] As a further improvement to the above solution, the bottom of the support block is fixedly connected to the top of the base, the end of the damper away from the support block is fixedly connected to the surface of the main body, the top of the fixing block is fixedly connected to the inner wall of the main body, the bottom of the inner shell is fixedly connected to the top of the main body, and the surface of the sliding cover is slidably connected to the inner wall of the inner shell.

[0010] As a further improvement to the above solution, the number of the support block, damper, buffer groove and slider are all set to four, and they are evenly distributed on the top of the base with the base as the center.

[0011] Through the above technical solution, by setting a buffer chute, when the device is in use, mechanical vibration is transmitted to the bottom of the main body, causing the slider to slide on the inner wall of the buffer chute. At the same time, the dampers set on both sides of the main body absorb the vibration, cancel out the structural vibration of the device, prevent the structural vibration from accelerating the wear of the device, extend the service life of the device, and ensure the structural stability of the device during use.

[0012] As a further improvement to the above solution, the number of spring damping blocks is set to four, and the spring damping blocks are evenly distributed on the inner wall of the main body with the base as the center.

[0013] Through the above technical solution, by setting a spring damping block, the spring damping block absorbs the vibration transmitted to the bottom of the main body when the device is in use, reduces the noise generated during operation, and improves the comfort of using the device.

[0014] As a further improvement to the above solution, the processing mechanism includes a mounting frame, a first motor fixedly connected to the inner wall of the mounting frame, a first threaded rod fixedly connected to the output end of the first motor, a workpiece table threadedly connected to the surface of the first threaded rod, a feeding chute opened on the top of the main body, a processing frame fixedly connected to the top of the main body, a second motor fixedly connected to the top of the processing frame, a rotating shaft fixedly connected to the output end of the second motor, a driving gear fixedly connected to the surface of the rotating shaft, a driven gear meshing with the surface of the driving gear, a second threaded rod fixedly connected to the inner wall of the driven gear, a milling head threadedly connected to the surface of the second threaded rod, and a limit rod fixedly connected to the inner wall of the processing frame.

[0015] As a further improvement to the above solution, the surface of the mounting bracket is fixedly connected to the surface of the main body, the surface of the first threaded rod is rotatably connected to the inner wall of the main body, and the surface of the workpiece table is slidably connected to the inner wall of the feeding chute.

[0016] Through the above technical solution, by setting a first threaded rod, the first motor drives the first threaded rod to rotate, driving the workpiece table to move at the top of the main body under the limit of the feeding chute, and transporting the workpiece to be processed to the bottom of the processing frame.

[0017] As a further improvement to the above solution, the surface of the second threaded rod is rotatably connected to the inner wall of the machining frame, and the inner wall of the milling head is slidably connected to the surface of the limiting rod.

[0018] The above technical solution involves setting a second threaded rod, which drives the rotating shaft to rotate. This rotating shaft then drives the drive gear to rotate, which in turn drives the second threaded rod to rotate. This drives the milling head to move within the processing frame under the limit of the limiting rod, adjusting the processing position of the milling head and improving the practicality of the device.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model incorporates a noise reduction mechanism, specifically by using sound-absorbing cotton between the outer and inner shells. This multi-layered structure absorbs noise during use, isolating it within the device and improving its practicality. A buffer groove is also included; during use, mechanical vibrations are transmitted to the bottom of the main body, causing the slider to slide along the inner wall of the groove. Simultaneously, dampers on both sides of the main body absorb and counteract the structural vibrations, preventing accelerated wear and extending the device's lifespan and ensuring structural stability. Finally, spring damping blocks absorb vibrations transmitted to the bottom of the main body, reducing operational noise and improving user comfort.

[0021] This utility model improves the practicality of the device by setting up a processing mechanism. Specifically, it uses a first threaded rod, which is driven by a first motor to rotate. This drives the workpiece table to move at the top of the main body under the limiting position of the feeding chute, transporting the workpiece to be processed to the bottom of the processing frame. By setting up a second threaded rod, a second motor drives a rotating shaft to rotate, which in turn drives a drive gear to rotate, which in turn drives the second threaded rod to rotate. This drives the milling head to move inside the processing frame under the limiting position of a limiting rod, adjusting the processing position of the milling head. Attached Figure Description
