Description

Technical Field

[0001] The invention relates to the technical field of machine tool bed processing, in particular to a drilling device used for machine tool bed processing. Background Art

[0002] When machining a machine tool bed, it is often necessary to drill holes in the machine tool bed in order to meet the needs of component installation, ventilation and heat dissipation. During the drilling process, it is necessary to strictly control the parameters such as the position, diameter and depth of the drilling to ensure that the quality and accuracy of the drilling meet the requirements. When drilling, the machine tool bed is usually clamped by a clamping mechanism. When clamping the machine tool bed, in order to ensure the drilling accuracy of the workpiece, before drilling the machine tool bed, the drill bit needs to be aligned with the center position of the top surface of the workpiece to adjust the starting coordinate system of the drill bit, and then the drilling position is determined by moving the drill bit, so that the drilling device needs to spend a lot of time when drilling the machine tool bed.

[0003] The patent document with the announcement number CN218694116U discloses a drilling device for machine tool base processing, which relates to the technical field of machine tool base processing, including a punching protection base, a punching device body is fixedly installed inside the punching protection base, a moving device is fixedly installed inside the punching protection base, and a limiting device is arranged on the surface of the moving device, the moving device includes a bottom plate, a second driving motor and a limiting seat, the limiting seat is fixedly installed on the surface of the bottom plate, the limiting device includes a fixed plate, an elastic member and a limiting L-shaped plate, and an adjusting rod is provided to push the push plate, so as to cooperate with the electric telescopic rod to push the buffer plate, thereby realizing the limiting L-shaped plate to limit the base to a certain extent, avoiding the displacement of the machine tool base, resulting in deviation during drilling, and then resulting in the problem of reduced utilization efficiency of the device, thereby improving the use efficiency of the device, but the patent still has the following problems in actual use:

[0004] The drilling device sets a limiting L-shaped plate to limit the base to a certain extent to prevent deviation during drilling. However, since the limiting L-shaped plate can only clamp and fix the two sides of the workpiece, it is difficult to install the workpieces in the same position when drilling workpieces of the same specification, and it is also difficult to quickly find the center point of the top surface of the workpiece when installing workpieces of different specifications. As a result, it is necessary to calibrate the coordinate system of the center of the top surface of each workpiece when drilling, so that the drilling device needs to perform tool alignment work multiple times, resulting in low drilling efficiency.

[0005] Therefore, we propose a drilling device for machine tool bed processing in order to solve the above-mentioned problems. Summary of the invention

[0046] Working principle: Figure 1-Figure 9 As shown, when using the device, first, the machine tool bed is placed above the pre-positioning plate 416 above the processing base 3. At this time, the telescopic spring 417 supports the pre-positioning plate 416, and drives the lifting screw 407 to rotate by controlling the motor 2 406, so that the lifting screw 407 drives the C-frame 409 to slide and rise at the lifting slide bar 408, so that the support plate 410 on the bottom surface of the C-frame 409 drives the lifting plate 411 to slide and rise in the limiting rod 419 through the limiting groove 418, so that the top surface of the machine tool bed falls roughly below the pressing angle 502, and then drives the transverse bidirectional screw 404 to rotate by controlling the motor 1 403 on one side of the fixed seat 401, so that the transverse bidirectional screw 404 drives the transverse moving seat 405 to move and shrink on the guide rod 402, and at this time the lower end of the C-frame 409 is in the sliding groove 412. The lifting plate 411 is controlled to rise again, so that the top surface of the machine bed is fitted with the bottom surface of the pressing angle 502. At this time, the telescopic spring 417 is contracted a little, and then the transverse bidirectional screw 404 and the longitudinal bidirectional screw 421 are controlled to rotate again, so that the pressing angle 502 is fitted with the corner of the top surface of the machine bed, and then the lifting plate 411 is controlled to rise again, so that the rotating support rod 414 slides in the make way groove 415, and the pre-positioning plate 416 pushes the telescopic spring 417 to contract into the sink groove 413, so as to realize the positioning of the machine bed. At this time, the middle of the top surface of the machine bed is aligned with the center position of the drill bit 2.

[0047] Secondly, when there is a chamfer or irregular clamping on the edge of the top surface of the machine tool bed, by pressing the adjustment plate 518, the adjustment plate 518 drives the connecting rod 517 to descend on the top surface of the fixed block 511. At this time, the connecting rod 517 on one side pushes the inclined groove 515 through the inclined block 516, so that the inclined groove 515 drives the locking block 514 to shrink toward the reset spring 513 on the side of the adjusting groove 512. At this time, the locking block 514 is separated from the connecting block 510, and the pressing angle 502 can be rotated to make the pressing angle 502 push the arc rod 509 to rotate at the rotating shaft 501, so that the pressing angle 502 is in contact with one side of the fixed block 511, and then the adjusting plate 518 is released to make the locking block 514 lock the position of the connecting block 510 again.

[0048] Finally, when the pressing plate 503 contacts the edge of the top surface of the machine tool bed, the irregular edge will push the contact block 507 to rotate at the rotating rod 506, and cause the extrusion spring 508 to expand and contract. Then the rotating rod 506 slides and contracts into the contraction groove 504, and causes the contraction spring 505 to contract, so that the contact block 507 fits tightly with the edge of the top surface of the machine tool bed. According to the processing needs, the drill bit 2 can be controlled to move on the driving bracket 1 and drill holes in the machine tool bed.
