Abstract
Description
Technical Field
[0001] This utility model relates to the field of boring processing technology, and in particular to a boring processing machine tool. Background Technology
[0002] Boring refers to the further processing of forged, cast, or drilled holes. Boring can enlarge the hole diameter, improve accuracy, reduce surface roughness, and can also better correct the deviation of the original hole axis. For example, when machining flanges, it is necessary to bore the bolt holes.
[0003] The prior art patent CN216398077U discloses a boring machine tool with an adjustable workstation. It features a fixed platform, linear slide, sliding block, connecting plate, second motor, gear, limiting plate, and gear edge at the bottom of the boring assembly. When machining workpieces of different sizes, the second motor drives the gear to mesh with the gear edge of the limiting plate, causing the connecting plate to move. The connecting plate then moves the sliding block on the upper end of the linear slide, thus adjusting the position of the boring assembly without needing to adjust the workpiece position. However, during use, after machining one hole, the operator needs to readjust the position of the boring assembly to machine the next hole, wasting a significant amount of time and resulting in low processing efficiency and inconvenience. Therefore, this utility model discloses a boring machine tool to meet these needs. Utility Model Content

Then, through the hexagonal rotating rod, strip block, adjusting screw and moving block, it drives the boring assembly to move up and down to bore the flange. During this process, the rotation of the drive shaft also drives the connecting gear to rotate intermittently through the first bevel gear, second bevel gear, connecting shaft and incomplete gear. Then, through the damping rotating cylinder, hexagonal rotating rod, strip block, adjusting screw and moving block, it drives the boring assembly to move intermittently in a circular motion. Thus, the boring assembly can move up and down and intermittently in a circular motion at the same time, so as to achieve the purpose of automatically and uniformly boring the flange.

[0014] 2. In this utility model, when the adjustment knob is rotated, the boring assembly moves horizontally via the adjustment screw and the moving block. The rotation radius of the boring assembly can be adjusted to accommodate flange workpieces of different sizes. When the pull block is pulled or released, the insertion rod moves out of or into the insertion hole in conjunction with the return spring, loosening or fixing the connecting block.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example: Reference Figures 1-4The boring machine tool shown includes a machining table 1 and a boring assembly 2. Multiple fixed plates are evenly fixedly installed on the top of the machining table 1. Electric push rods 29 are fixedly installed on the sides of the multiple fixed plates. The output end of the electric push rod 29 passes through the fixed plate and is fixedly installed with an L-shaped clamping plate 30. When the electric push rod 29 is started, it will drive the L-shaped clamping plate 30 to move horizontally, thereby clamping and fixing the flange.
[0023] Two support plates 3 are fixedly installed on the top of the processing table 1. A servo motor 4 is fixedly installed on the side of the support plate 3. A drive shaft 5 is fixedly installed on the output end of the servo motor 4. An eccentric cam 6 is fixedly sleeved on the drive shaft 5. A mounting plate 7 is fixedly installed on the side of the two support plates 3 that are close to each other. A mounting hole is opened on the top of the mounting plate 7. A damping cylinder 8 is rotatably installed in the mounting hole. It should be noted that the damping cylinder 8 can only rotate and will not move up and down. The damping cylinder 8 has a large rotational friction force, that is, the damping cylinder 8 will not rotate when no external force is applied. A hexagonal rotating rod 9 is slidably sleeved inside the damping cylinder 8. The boring assembly 2 is eccentrically connected to the bottom end of the hexagonal rotating rod 9 through an adjustment unit. A reciprocating moving plate 10 that fits against the eccentric cam 6 is rotatably installed on the top end of the hexagonal rotating rod 9. A guide reset unit for pressing the reciprocating plate 10 vertically upward is installed on the plate 7. The guide reset unit includes two vertical guide rods 17 fixedly installed on the bottom of the reciprocating plate 10. Two guide holes are opened on the top of the mounting plate 7. The two vertical guide rods 17 are slidably installed in the two guide holes respectively. Multiple compression springs 18 are fixedly installed on the top of the mounting plate 7 and the bottom of the reciprocating plate 10. A connecting plate 11 is fixedly installed on the side of the support plate 3. A connecting rotating hole is opened on the top of the connecting plate 11. A connecting rotating shaft 12 is rotatably installed in the connecting rotating hole. An incomplete gear 13 is detachably installed at the bottom end of the connecting rotating shaft 12. A connecting gear 14 adapted to the incomplete gear 13 is fixedly sleeved on the damping rotating cylinder 8. A gear transmission unit that makes the connecting rotating shaft 12 rotate synchronously is connected to the drive rotating shaft 5.
[0024] With the above structure, when the servo motor 4 is started, it will drive the drive shaft 5 to rotate. The rotation of the drive shaft 5 will drive the eccentric cam 6 to rotate eccentrically. At this time, with the cooperation of the vertical guide rod 17 and the compression spring 18, the eccentric rotation of the eccentric cam 6 will drive the reciprocating plate 10 to move up and down reciprocally. In turn, the hexagonal rod 9 and the adjustment unit will drive the boring assembly 2 to move up and down together to perform boring machining on the flange. During this process, the rotation of the drive shaft 5 will also drive the connecting shaft 12 to rotate synchronously through the gear transmission unit. The rotation of the connecting shaft 12 will drive the incomplete Gear 13 rotates together, and the rotation of incomplete gear 13 drives the connecting gear 14 to rotate intermittently. The intermittent rotation of the connecting gear 14 drives the boring assembly 2 to move intermittently in a circular motion through the damping cylinder 8, hexagonal rotating rod 9, and adjusting unit. This allows the boring assembly 2 to move up and down while intermittently moving in a circular motion, thereby achieving the purpose of automatically and uniformly boring the flange. It eliminates the need for frequent manual adjustment of the position of the boring assembly 2, improves processing efficiency, and is simple and convenient to use. It has good practicality and good promotion value.
[0025] like Figure 2 As shown, the gear transmission unit includes a first bevel gear 15 fixedly sleeved on the drive shaft 5, and a second bevel gear 16 meshing with the first bevel gear 15 is fixedly installed at the top of the connecting shaft 12. When the drive shaft 5 rotates, it drives the first bevel gear 15 to rotate, and the rotation of the first bevel gear 15 drives the second bevel gear 16 to rotate together, which in turn drives the connecting shaft 12 to rotate synchronously, thus achieving the function of synchronous transmission.
[0026] like Figure 1 and Figure 4 As shown, the adjustment unit includes a strip block 24 fixedly mounted on the bottom end of a hexagonal rotating rod 9. A strip groove is formed at the bottom of the strip block 24, and a moving block 25 is slidably mounted within the groove. The boring assembly 2 is fixedly mounted on the bottom of the moving block 25. A screw hole is formed on the inner side wall of the strip groove, and an adjusting screw 26 is rotatably mounted within the screw hole. The moving block 25 is threaded onto the adjusting screw 26, and an adjusting knob 27 is fixedly mounted on one end of the adjusting screw 26. When the adjusting knob 27 is rotated, the adjusting screw 26 rotates, causing the moving block 25 to move horizontally, which in turn causes the boring assembly 2 to move horizontally as well. Therefore, the rotation radius of the boring assembly 2 can be adjusted to accommodate flange workpieces of different sizes.
[0027] like Figure 4As shown, the top of the strip block 24 has a locking screw hole that communicates with the screw rod's rotating hole. A locking bolt 28 is threaded into the locking screw hole, and the bottom end of the locking bolt 28 abuts against the top of the adjusting screw 26. When the locking bolt 28 is rotated, the adjusting screw 26 can be tightened or loosened in conjunction with the locking screw hole. This effectively reduces the change in the rotation radius of the boring assembly 2 caused by the rotation of the adjusting screw 26 during the machining process.
[0028] like Figure 3 As shown, a connecting sleeve 19 is fixedly installed at the bottom of the connecting shaft 12, and a connecting block 20 is slidably installed inside the connecting sleeve 19. An incomplete gear 13 is fixedly installed on the bottom of the connecting block 20. A sliding hole is opened on the side of the connecting sleeve 19, and a plug rod 21 is slidably installed inside the sliding hole. A plug hole is opened on the side of the connecting block 20, and one end of the plug rod 21 extends into the plug hole. A pull block 22 is fixedly installed on the other end of the plug rod 21. A reset spring 23 is fixedly installed on the side of the connecting sleeve 19 and the pull block 22. When the pull block 22 is pulled, the insertion rod 21 will move out of the insertion hole, and the connecting block 20 will be loosened. At this time, the incomplete gear 13 can be directly removed for replacement. When the pull block 22 is released, the pull block 22 will be automatically reset under the elastic force of the return spring 23, which will then drive the insertion rod 21 to automatically insert into the insertion hole, and fix the connecting block 20 in the connecting sleeve 19. This allows the flange workpiece with different hole numbers to be adapted by replacing the incomplete gear 13 with different tooth numbers.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
