Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically a five-axis machining center suitable for the production of various mechanical parts. Background Technology

[0002] Five-axis machining centers, also known as five-axis linkage machining centers, are high-tech, high-precision machining centers specifically designed for machining complex curved surfaces. These machining center systems have a significant impact on a country's aerospace, military, scientific research, precision instruments, and high-precision medical equipment industries. Five-axis linkage CNC machining center systems are the only means of machining impellers, blades, marine propellers, heavy-duty generator rotors, steam turbine rotors, and large diesel engine crankshafts.

[0003] For example, Chinese Patent CN221640210U discloses a five-axis machining center suitable for the production of various mechanical parts. Addressing the problem that existing equipment uses two sets of clamps to hold shaft-shaped parts and block-shaped parts separately, resulting in encroachment on the internal space of the machining center and increased construction costs, the following solution is proposed: A five-axis machining center suitable for the production of various mechanical parts includes a protective housing. Symmetrical support plates are welded to the bottom of the protective housing. At the ends of the two support plates that are close to each other, a rotating shaft with a rolling bearing at one end is inserted through a through hole. At the ends of the two rotating shafts that are close to each other, the same rotating frame is bolted to them. This invention uses several clamping electric cylinders to control the extension and retraction of telescopic rods, thereby controlling several movable clamping plates to jointly clamp the shaft-shaped parts and block-shaped parts, reducing the volume of the clamping components and effectively lowering construction costs.

[0004] The technical solution described in this plan does not have the function of collecting metal dust during actual use, which means that users need to clean it after processing, which is very inconvenient and reduces the practicality of the five-axis machining center. Utility Model Content

[0005] The purpose of this invention is to provide a five-axis machining center suitable for the production of various mechanical parts, so as to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A five-axis machining center suitable for producing various mechanical parts includes a main body, which includes a base. A back plate is connected to the back of the base. A square groove is formed in the center of the back plate. A dust removal mechanism is provided inside the square groove. The dust removal mechanism includes a negative pressure box. One end of the outer wall of the negative pressure box is connected to the inner wall of the square groove, and the end of the negative pressure box away from the square groove extends to the outside of the back plate. A first opening is formed on the front of the negative pressure box, and a pair of through holes are formed at the top of the negative pressure box. Negative pressure fans are installed on the top surface of the negative pressure box at the pair of through holes. Filter screens are embedded at the bottom and top of the negative pressure fans. A collection box is provided inside the negative pressure box. The outer wall of the collection box is clearance-fitted with the inner wall of the negative pressure box, and a second opening is formed on the front of the collection box at the first opening.

[0008] Furthermore, the negative pressure box has a first threaded hole at each of the four corners on the back, and a baffle is provided on the back of the negative pressure box. The baffle has a second threaded hole at each of the four corners, and bolts are threadedly connected between the first threaded hole and the second threaded hole.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the first threaded hole, the second threaded hole and the bolt, after the metal dust is collected inside the collection box, the bolt can be unscrewed with a tool to remove the baffle from the negative pressure box. The back of the negative pressure box is hollow, which makes it easy to remove the collection box from the negative pressure box for metal dust treatment.

[0010] Furthermore, a five-axis rotary table body is installed at the upper center of the base. The five-axis rotary table body includes a fixed base, a first rotary table is rotatably connected inside the fixed base, and a second rotary table is rotatably connected to the upper end of the first rotary table. A first mounting groove is opened inside one side of the fixed base, and a first servo motor is installed inside the first mounting groove. The output end of the first servo motor is connected to the first rotary table. A second mounting groove is opened inside the bottom end of the first rotary table, and a second servo motor is installed inside the second mounting groove. The output end of the second servo motor is connected to the second rotary table.

[0011] The beneficial effect of adopting the above-mentioned further solution is that by installing the first servo motor, it is convenient to drive the first turntable to rotate when it is working, and by installing the second servo motor, it is convenient to drive the second turntable to rotate when it is working.

[0012] Furthermore, the upper end of the second turntable is provided with a clamping mechanism, which includes a circular mounting base. The bottom end of the circular mounting base is connected to the upper end of the second turntable, and the top surface of the circular mounting base is provided with several sliding grooves. A slider is slidably connected inside the sliding grooves, and a clamping block is connected to the upper end of the slider.

[0013] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the slide and the slider, with four slides and four sliders, when all four sliders slowly move towards the center, it is convenient to clamp block-shaped parts or shaft-like parts.

[0014] Furthermore, a circular plate is rotatably connected inside the circular mounting base. Several arc-shaped grooves are formed on the circular plate. A movable rod is slidably connected inside the arc-shaped grooves. Limiting plates are fitted on the outer side of the movable rod at the upper and lower ends of the circular plate. The opposite sides of a pair of limiting plates are respectively attached to the upper and lower ends of the circular plate. A second motor is installed at the bottom of the circular mounting base. The output end of the second motor is connected to the circular plate through a transmission.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, since four arc-shaped grooves are opened on the upper end surface of the circular plate, and one end of the four arc-shaped grooves is close to the center and the other end is far away from the center, by installing a second motor, when it is working, it is easy to drive the circular plate to rotate, and under the action of the arc-shaped grooves, the four moving rods drive the slider to move closer to the center or expand outwards. At the same time, under the action of the limiting plate, the position of the moving rods is limited, preventing the moving rods from falling off and separating from the arc-shaped grooves during the movement.

[0016] Furthermore, mounting covers are installed on both sides of the upper end of the base, and a top plate is connected between the two mounting covers near the upper end. A pair of electric slide rails are connected to the bottom end of the top plate, and electric sliders are slidably connected to the outside of each pair of electric slide rails. A linear motor is connected to the bottom end of each pair of electric sliders, and a hydraulic cylinder is installed at the moving end of the linear motor. A fixed frame is connected to the movable end of the hydraulic cylinder, and a first motor is installed at the upper end of the inside of the fixed frame. A cutting tool is driven to the output end of the first motor.

[0017] The beneficial effects of adopting the above-mentioned further solution are that, through the combined use of electric slide rail and electric slider, when they are working, it is convenient to realize the horizontal movement of the tool; when the linear motor is working, it is convenient to realize the forward and backward movement of the tool; when the hydraulic cylinder is working, it is convenient to realize the lifting and lowering movement of the tool; by setting a fixed frame, it is convenient to install the first motor; by installing the first motor, when it is working, it is convenient to drive the tool to rotate and thus process the part.

[0018] Furthermore, the upper end of the base and the front of the top plate are provided with movable grooves, and movable blocks are slidably connected to both sides of the interior of the two movable grooves. A soundproof door is connected between a pair of movable blocks on the same side, and the inner wall of the soundproof door is fitted with the outer wall of the mounting cover with a clearance.

[0019] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the moving slot and the moving block, it is easy to pull a pair of soundproof doors toward the center, thereby blocking the sound generated by the cutting tool during the machining of the part.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This five-axis machining center, applicable to the production of various mechanical parts, generates a lot of metal dust during the machining process. At this time, by starting the negative pressure fan, the airflow is drawn out, creating a negative pressure in the collection box inside the negative pressure box. Under the action of the first and second openings, the metal dust generated during machining enters the collection box under the negative pressure, thus achieving the purpose of dust removal. Through the cooperation of the first threaded hole, the second threaded hole, and the bolt, after the metal dust is collected inside the collection box, the bolt is unscrewed with a tool to remove the baffle from the negative pressure box. The back of the negative pressure box is hollow, making it easy to remove the collection box from the negative pressure box for metal dust treatment. By opening a square groove in the center of the back plate, both ends of the negative pressure box are located outside the back plate. Attached Figure Description

[0033] Specifically, the working principle of this five-axis machining center, suitable for the production of various mechanical parts, is as follows: When the second motor 3009 is started, it drives the circular plate 3005 to rotate.
