Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing equipment, in particular to a mechanical processing machine tool with an adjustable spindle box height. Background Art

[0002] In the machining industry, machine tools, as core equipment, undertake the important task of performing various machining operations such as drilling, milling, and turning on various workpieces. The quality of their performance directly affects the quality, precision, and production efficiency of the machined workpieces. With the continuous development of the manufacturing industry, the market demand for diversified and personalized products is increasing, which requires machining machine tools to be able to adapt to workpieces of different sizes, shapes, and processing requirements.

[0003] The spindle boxes of existing machining centers are mostly fixed structures. When machining workpieces of varying heights, the non-adjustable spindle box often requires operators to use auxiliary tools such as spacers to adjust the relative position between the workpiece and tools such as drills. This not only increases operational difficulty and workload, but can also lead to reduced machining accuracy and even safety accidents due to factors such as unstable placement or inappropriate size of the spacers. Furthermore, for workpieces with complex shapes, such as those with inclined or specially curved surfaces, traditional machine tools struggle to achieve multi-angle precision machining. Multiple workpiece clamping and tedious angle adjustments are often required, severely impacting machining efficiency and product quality. High-speed operation and frequent lifting and lowering of the machine tool's spindle box generate significant impact forces. Without an effective buffering and protection mechanism, this can easily damage the spindle box and related components, shortening the machine tool's service life and increasing production costs. Traditional machine tools also have shortcomings in waste collection and disposal. Waste generated during machining is often scattered around the machine tool, requiring regular manual cleaning, which is not only labor-intensive but also can affect the normal operation of the machine tool and the machining environment.

[0038] Furthermore, a first servo motor 5 is fixedly connected to the upper surface of the lifting platform 103, and a rotating shaft 501 is movably connected to the left and right sides of the lifting platform 103, and the upper surface of one rotating shaft 501 is connected to the output end of the first servo motor 5 through a coupling, and the outer wall of the rotating shaft 501 is threadedly connected to the spindle box 502, and the upper surface of the spindle box 502 is fixedly connected to the second servo motor 503, and the output end of the lower surface of the second servo motor 503 is fixedly connected to the drill bit 504, and the outer walls of a pair of rotating shafts 501 are fixedly connected to the second pulley 505, and the upper and lower sides of the lifting platform 103 are fixedly connected to the return spring 506, and the output end of the return spring 506 is fixedly connected to the damping buffer plate 507, and the upper and lower sides of the lifting platform 103 are provided with a return spring 506 and a damping buffer plate 507, which can enable the spindle box 502 to buffer the force of descending or lifting, and the second servo motor 503 can enable the drill bit 504 to process the workpiece.

[0039] Furthermore, the left and right sides of the inner wall of the lifting platform 103 are fixedly connected with the first slide rail groove 6, the interior of the lower surface of the first slide rail groove 6 is fixedly connected with the mounting block 601, and the left and right sides of the upper surface of the mounting block 601 are provided with a cavity 602, the interior of the cavity 602 is fixedly connected with a buffer spring 603, the output end of the upper surface of the buffer spring 603 is fixedly connected with the second slide rail groove 604, the interior of the second slide rail groove 604 is slidably connected with a sliding plate 605, and the buffer spring 603 is installed in the interior of the cavity 602. When the second slide rail groove 604 descends, the buffer spring 603 is squeezed, thereby reducing the descending force of the second slide rail groove 604.

[0040] Working Principle: After the machine tool is started, the drive motors and servo motors in the main unit 1 are in standby mode, and the air pump 308 completes initialization preparation. The operator prepares the corresponding fixtures and processing tools according to the size and shape of the workpiece to be processed and installs them in the corresponding positions of the machine tool, such as installing the tool on the drill bit 504 and placing the workpiece on the placement table 405;

[0041] The first drive motor 104 on one side of the main unit 1 is started, and drives the first threaded rod 106 to rotate through the first pulley 108. The first threaded rod 106 is threadedly connected to the second adjustment plate 204. The second adjustment plate 204 moves back and forth under the drive of the first threaded rod 106, thereby driving the entire rotating unit 3 to move, adjusting the horizontal position of the workpiece to a suitable processing position;

[0042] The second drive motor 203 in the adjustment unit 2 is started, driving the first rotating shaft 205 to rotate. The first rotating shaft 205 is fixedly connected to the rotating frame 301, thereby driving the rotating frame 301 to rotate, and realizing the preliminary rotation adjustment of the workpiece within a larger angle range. At the same time, the air pump 308 on the upper surface of the rotating frame 301 is started, and the air rod 309 is extended and retracted under the action of the air pump 308, pushing the fixed block 3010 to move. The fixed block 3010 is connected to a tooth plate 306, driving the tooth plate 306 to move through the sliding rod 3 05 moves left and right in the mounting groove 304. Since the latch plate 306 is connected to the meshing gear 303, the movement of one latch plate 306 drives the meshing gear 303 to rotate, and the meshing gear 303 then meshes and transmits with the other latch plate 306, so that the two latch plates 306 can be expanded to both sides or retracted to the middle. The latch plate 306 is connected to the mounting plate 4 through the support rod 307. The movement of the mounting plate 4 drives the entire clamping mechanism and the workpiece to achieve more precise angle adjustment to meet the requirements of different processing angles.

[0043] The first servo motor 5 on the upper surface of the lifting platform 103 is started, driving a rotating shaft 501 to rotate through a coupling. The pair of rotating shafts 501 are synchronously driven by a second pulley 505. When the rotating shaft 501 rotates, the spindle housing 502 moves up and down along the rotating shaft 501. The operator can accurately control the rotation of the first servo motor 5 according to the required processing height of the workpiece, thereby adjusting the spindle housing 502 to the appropriate height, so that the drill bit 504 can accurately process the workpiece;

[0044] After the spindle housing 502 is adjusted to the appropriate height, the second servo motor 503 on the upper surface of the spindle housing 502 is started, driving the drill bit 504 to rotate at high speed. At this time, the various moving parts of the machine tool work together to perform drilling operations on the workpiece according to the predetermined processing program. During the processing, since the workpiece is firmly fixed by the clamping mechanism and the position and angle are accurately adjusted, the processing accuracy and quality can be guaranteed.

[0045] During the processing, the waste generated will fall into the collecting slope trough 105 inside the main unit 1. The auger conveyor 107 is driven synchronously by the first pulley 108 to convey the waste in the collecting slope trough 105 out of the main unit 1, realizing the automatic collection function, reducing the workload of manual waste cleaning and keeping the processing environment clean.

[0046] During the up and down movement of the spindle housing 502, the return spring 506 and the damping buffer plate 507 play a role. When the spindle housing 502 descends, the return spring 506 and the damping buffer plate 507 are squeezed. The return spring 506 provides elastic buffering force, and the damping buffer plate 507 consumes energy through damping, thereby buffering the downward force of the spindle housing 502 and protecting the spindle housing 502 and other parts of the machine tool from damage.

[0047] When the spindle box 502 moves up and down, the sliding plate 605 is connected to the spindle box 502 and slides in the second slide groove 604. The second slide groove 604 slides up and down under the action of the spindle box 502. When the second slide groove 604 descends, it will squeeze the buffer spring 603 installed in the cavity 602. The buffer spring 603 provides additional buffering force, and works together with the return spring 506 and the damping buffer plate 507 to achieve secondary buffering of the downward force of the spindle box 502, thereby further improving the stability and reliability of the machine tool operation.
