Description
Technical Field
[0001] This utility model relates to the field of fixed beam gantry technology, specifically a fixed beam gantry processing and cutting device. Background Technology
[0002] The fixed-beam gantry is a classic structural form of gantry machine tool. Its core feature is that the crossbeam is fixed and the machining function is achieved through the relative movement of the worktable, column and actuators.
[0003] It is common practice to install a cutting device at the lower end of a fixed beam gantry to cut different materials. However, since different materials require different types of cutting, when the material needs to be changed, the cutter at the lower end of the fixed beam gantry needs to be replaced. Since the cutter is usually connected to the main shaft by bolts, the disassembly or replacement process is not only cumbersome, but also reduces work efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a fixed beam gantry machining and cutting device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed beam gantry machining and cutting device, comprising a main shaft, the upper end of which is connected to a fixed beam gantry, a mounting groove at the lower end of the main shaft, a mounting block being engaged inside the mounting groove, four side grooves being mounted in a rectangular equidistant array at the lower end of the main shaft, all four side grooves being connected to the mounting groove, an extrusion plate being slidably connected inside the side grooves, and multiple extrusion plates contacting the side walls of the mounting blocks, a fixed shaft being mounted at the lower end of the mounting blocks, a limiting disc being mounted at the lower end of the fixed shaft, two limiting components being symmetrically mounted on the outer wall of the main shaft, both limiting components contacting the lower end of the limiting disc, a fixed disc being threadedly connected to the lower end of the limiting disc, and a cutter being mounted at the lower end of the fixed disc.
[0006] Preferably, a connecting post is installed at the center of the mounting groove, and an opening groove is provided at the center of the upper end of the mounting block, with the connecting post and the opening groove being snap-fitted together.
[0007] Preferably, an electric push rod is installed inside the side groove, and the electric push rod is connected to one end of the extrusion plate.
[0008] Preferably, the limiting assembly includes a fixed sleeve, a lifting rod, and a limiting plate. The fixed sleeve is fixedly installed on the outer wall of the main shaft. The lower end of the fixed sleeve is sleeved with the lifting rod. The lower end of the lifting rod is installed with a transverse limiting plate. The inner wall of the lifting rod is in contact with the outer wall of the limiting disc. The upper end of the limiting plate is in contact with the lower end of the limiting disc.
[0009] Preferably, an annular plate is fixedly mounted on the outside of the spindle, and the upper ends of the two limiting components are fixedly connected to the lower end of the annular plate.
[0010] Preferably, both the limiting disc and the fixing disc have multiple threaded holes equidistantly spaced on their surfaces, and two of the threaded holes on the same vertical center line are connected by a fixing bolt.
[0011] Preferably, a snap-fit block is installed at the upper center of the limiting plate, and two snap-fit grooves are symmetrically opened at the lower end of the limiting disc. The snap-fit grooves are used in conjunction with the snap-fit block, and two soft pads are symmetrically installed on the left and right sides of the snap-fit block at the upper end of the limiting plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are: During installation, the fixed plate and the limiting disc are first connected by multiple fixing bolts. Then, the two limiting components are moved downwards. At this time, the mounting block is connected to the mounting groove through the connecting column and the opening slot. Four electric push rods drive the extrusion plates to move towards the mounting block until the four extrusion plates contact the side wall of the mounting block, forming a multi-angle clamping effect. Then, two lifting rods drive the limiting plates upwards until the upper end of the limiting plate contacts the lower end of the limiting disc. The limiting components limit the limiting disc vertically, and the four extrusion plates limit the mounting block and the limiting disc horizontally. The limiting disc and the fixed plate are connected by multiple threaded fixing bolts, thus limiting the position of the cutter from multiple angles in the vertical and horizontal directions. During disassembly, only the limiting components and the four extrusion plates need to be loosened to remove the mounting block from the mounting groove. At this time, the cutter will be disengaged from the main shaft. The disassembly and installation processes are quick and convenient. Attached Figure Description

[0017] like Figures 1 to 4As shown, the fixed beam gantry machining and cutting device of this embodiment includes a main spindle 1. The upper end of the main spindle 1 is connected to the fixed beam gantry, which can drive the main spindle 1 to rotate. This is conventional prior art and will not be described in detail. The lower end of the main spindle 1 has a mounting groove 8, which is a square groove. A mounting block 9 is engaged inside the mounting groove 8. Four side grooves 16 are installed in a rectangular equidistant array at the lower end of the main spindle 1. All four side grooves 16 are connected to the mounting groove 8. Extrusion plates 18 are slidably connected inside the side grooves 16. The four extrusion plates 18 move towards the mounting groove 8 until they contact the outer wall of the mounting block 9. The four extrusion plates 18 can limit the mounting block 9 in the horizontal direction. All the extrusion plates 18 are engaged with the mounting block 9. The side walls of the mounting block 9 are in contact with each other. A fixed shaft 4 is installed at the lower end of the mounting block 9. A limiting disc 5 is installed at the lower end of the fixed shaft 4. Two limiting components 3 are symmetrically installed on the outer wall of the main shaft 1. Both limiting components 3 are in contact with the lower end of the limiting disc 5. The limiting components 3 can limit the limiting disc 5 in the vertical direction. A fixed disc 6 is threadedly connected to the lower end of the limiting disc 5. A cutter 7 is installed at the lower end of the fixed disc 6. The limiting components 3 limit the limiting disc 5 in the vertical direction. The four extrusion plates 18 limit the mounting block 9 and the limiting disc 5 in the horizontal direction. The limiting disc 5 and the fixed disc 6 are threadedly connected by multiple fixing bolts 12, thereby limiting the position of the cutter 7 from multiple angles in the vertical and horizontal directions.
[0018] Specifically, a connecting post 15 is installed at the center of the mounting slot 8, and an opening slot is provided at the center of the upper end of the mounting block 9. The connecting post 15 and the opening slot are snapped together. The connection stability between the mounting slot 8 and the mounting block 9 can be enhanced by the snap-fit connection between the connecting post 15 and the opening slot.
[0019] Furthermore, an electric push rod 17 is installed inside the side groove 16. The electric push rod 17 is connected to one end of the extrusion plate 18. All four electric push rods 17 operate independently and can drive the extrusion plate 18 to slide inside the side groove 16. The extrusion plate 18 is slidably connected to the side groove 16 through a guide rail. It should be noted that the running distance of the electric push rod 17 is preset by an external program.
[0020] Furthermore, the limiting component 3 includes a fixed sleeve 301, a lifting rod 302, and a limiting plate 303. The fixed sleeve 301 is fixedly installed on the outer wall of the main shaft 1. The lower end of the fixed sleeve 301 is sleeved with the lifting rod 302. The lower end of the lifting rod 302 is equipped with a transverse limiting plate 303. The inner wall of the lifting rod 302 is in contact with the outer wall of the limiting disc 5. The upper end of the limiting plate 303 is in contact with the lower end of the limiting disc 5. The two lifting rods 302 drive the limiting plate 303 to move upward until the upper end of the limiting plate 303 is in contact with the lower end of the limiting disc 5, thereby fixing the limiting disc 5 in the vertical direction. An annular plate 2 is fixedly installed on the outside of the main shaft 1. The upper ends of the two limiting components 3 are fixedly connected to the lower ends of the annular plate 2. The annular plate 2 can enhance the connection strength of the two limiting components 3.
[0021] Furthermore, both the limiting disc 5 and the fixed disc 6 have multiple threaded holes 10 equidistantly spaced on their surfaces. Two threaded holes 10 on the same vertical center line are connected by a fixing bolt 12. The limiting disc 5 and the fixed disc 6 can be tightly connected by multiple fixing bolts 12.
[0022] Furthermore, a snap-fit block 13 is installed at the upper center of the limiting plate 303, and two snap-fit grooves 11 are symmetrically opened at the lower end of the limiting disc 5. The snap-fit grooves 11 are used in conjunction with the snap-fit block 13. Two soft pads 14 are symmetrically installed on the left and right sides of the snap-fit block 13 at the upper end of the limiting plate 303. Through the use of the snap-fit grooves 11 and the snap-fit block 13, the connection between the limiting plate 303 and the limiting disc 5 can be made more stable, and the two soft pads 14 can provide a certain cushioning effect.
[0023] The usage method of this embodiment is as follows: During installation, firstly, the fixed plate 6 and the limiting disc 5 are connected by multiple fixing bolts 12. Then, the two limiting components 3 are moved downwards. At this time, the mounting block 9 is connected to the mounting groove 8 through the connecting column 15 and the opening groove. The four electric push rods 17 drive the extrusion plate 18 to move towards the mounting block 9 until the four extrusion plates 18 contact the side wall of the mounting block 9, forming a multi-angle clamping effect. Then, the two lifting rods 302 drive the limiting plate 303 to move upwards until the upper end of the limiting plate 303 is in contact with the limiting disc 5. The lower end of the plate contacts the plate, and the limiting component 3 limits the vertical direction of the limiting disc 5. The four extrusion plates 18 limit the horizontal direction of the mounting block 9 and the limiting disc 5. The limiting disc 5 and the fixed disc 6 are connected by multiple fixing bolts 12, thereby limiting the position of the cutter 7 from multiple angles in the vertical and horizontal directions. When disassembling, it is only necessary to loosen the limiting component 3 and the four extrusion plates 18 to remove the mounting block 9 from the mounting groove 8. At this time, the cutter 7 will be disconnected from the main shaft 1. The disassembly and installation process is quick and convenient.
[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
