Description

Technical Field

[0001] This invention relates to the technical field of boring machines, specifically to a boring machine column device with a U-shaped guide rail layout. Background Technology

[0002] A boring machine is a machine tool that uses a boring bar to bore pre-drilled holes in a workpiece. Typically, the rotation of the boring bar is the primary motion, while the movement of the boring bar or workpiece is the feed motion. It is mainly used for machining high-precision holes or for finishing multiple holes in a single positioning operation. It can also be used to machine other surfaces related to hole finishing. Using different tools and accessories, it can also perform drilling, milling, and cutting operations with higher precision and surface quality than drilling machines. Boring machines are the main equipment for machining large box-shaped parts, including threading, machining outer diameters, and end faces.

[0003] The existing publication number CN201483023U discloses an automatic horizontal milling and boring machine, which relates to the field of machine tool technology. It includes a bed, a lower slide, an upper slide, a worktable, a spindle box, a column, a boring spindle, a feed servo motor, and an electrical system. The spindle box houses a spindle speed change transmission mechanism, which includes a spindle frequency converter motor, a speed change shaft, and two transmission shafts. The bed has four guide rails, increasing the overall rigidity and load-bearing capacity of the machine tool. The worktable clamping uses disc spring clamping and hydraulic release, greatly improving the reliability of the worktable clamping. The main motion is driven by a frequency converter motor, and the feed motion is driven by a servo motor, enabling stepless speed regulation of the spindle speed and feed rate, as well as automatic positioning of a single axis. The control system also incorporates automatic milling cycles, boring cycles, drilling cycles, and tapping cycles, greatly simplifying operation and significantly improving production efficiency. It is a horizontal milling and boring machine with automatic machining capabilities.

[0004] Most existing boring machine columns have guide rails located on the side of the column, resulting in a single support point and thus a risk of localized deformation. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a boring machine column device with a U-shaped guide rail layout. The U-shaped guide rail distribution enhances the moment of inertia of the U-shaped column section, effectively resisting deformation caused by cutting forces and vibrations. The U-shaped layout can simultaneously withstand radial cutting forces, axial loads, and overturning moments. By dispersing stress through multi-point support, it reduces the risk of local deformation. This invention solves the problem that most guide rails on existing boring machine columns are located on the side of the column, resulting in a single support point and thus the risk of local deformation.

[0006] To achieve the aforementioned U-shaped guide rail distribution, the cross-sectional moment of inertia of the U-shaped column is enhanced, effectively resisting deformation caused by cutting forces and vibrations. The U-shaped layout can simultaneously withstand radial cutting forces, axial loads, and overturning moments. By dispersing stress through multi-point support, the risk of local deformation is reduced. Therefore, this invention provides the following technical solution: A boring machine column device with a U-shaped guide rail layout, comprising a machine bed, a worktable mounted on the machine bed, a U-shaped column fixedly mounted on the right side of the machine bed, and U-shaped guide rails fixedly mounted on the inner wall of the U-shaped column, with two guide rails mounted on the U-shaped guide rails. Component A has two crossbars fixedly installed on its two guide rails. Connecting blocks are set on the two crossbars, and a spindle box is fixedly installed on the lower side of the connecting blocks. Two vertical blocks are fixedly installed on each of the two guide rails, and lead screws are threaded through the two vertical blocks. A housing is fixedly installed on the upper side of the U-shaped column. The housing is connected to the two lead screws. A rotary starter inside the housing can drive the lead screws to rotate back and forth. The lower ends of the two lead screws are connected to brackets through bearings. The brackets are fixedly connected to the U-shaped column. A sliding platform is set on the bed, and a secondary column is fixedly installed on the sliding platform.

[0007] Preferably, two guide rail assemblies b are connected to the U-shaped guide rail, and two support rods are fixedly installed on each of the two guide rail assemblies b. Vertical bars are movably sleeved on each of the four support rods, and the four vertical bars are fixedly connected to the spindle box.

[0008] Preferably, two reinforcing rods are fixedly installed on the two guide rail assemblies b, and cylinders are fixedly installed on the two guide rail assemblies b. A horizontal bar is fixedly installed at the rear end of the output shaft of the cylinder, and a block is fixedly installed on the rear side of the horizontal bar. Both blocks are fixedly connected to the inner rear wall of the U-shaped column.

[0009] Preferably, each mounting slot on the workbench is movably connected to a T-shaped block, and each T-shaped block is fixedly mounted with a movable block.

[0010] Preferably, a short strip is fixedly installed on the upper side of each of the moving blocks, and an L-shaped groove is opened on each short strip. A control rod is provided on the worktable, and the control rod is movably connected to each L-shaped groove.

[0011] Preferably, small columns are fixedly installed at both ends of the controllable rod, and hemispherical grooves are opened on the side of the two small columns that are far apart from each other. A ball is movably connected in each hemispherical groove. Limiting plates are fixedly installed on both sides of the worktable, and the side of the two limiting plates that are close to each other is respectively in contact with the two balls. Limiting blocks are fixedly installed on the rear side of the two limiting plates.

[0012] Preferably, each of the movable blocks has two sliding grooves, and several sets of small blocks are fixedly installed on the front of the worktable. Each small block is fixedly installed with a limit strip, and each limit strip is movably connected to each sliding groove. Two support plates are fixedly installed on the front of the worktable, and two vertical plates are fixedly installed on each of the two support plates.

[0013] Compared with the prior art, the present invention provides a boring machine column device with a U-shaped guide rail layout, which has the following advantages:

[0014] The boring machine column device with U-shaped guide rails enhances the moment of inertia of the U-shaped column section through the U-shaped distribution of the guide rails, effectively resisting deformation caused by cutting forces and vibrations. The U-shaped layout can simultaneously withstand radial cutting forces, axial loads, and overturning moments, and disperses stress through multi-point support, reducing the risk of local deformation.

[0015] The boring machine column device with the U-shaped guide rail can drive the two guide rail components b to move back and forth by retracting the output shaft of the cylinder. This, in turn, can drive the four support rods to move back and forth, which in turn can drive the spindle box to move back and forth, thereby adjusting the position of the spindle box.

[0016] The boring machine column device with this U-shaped guide rail allows users to move the T-block back and forth when too much debris accumulates in the mounting slot on the worktable. This clears the internal debris by moving the T-block back and forth, thus preventing the debris from accumulating for a long time and affecting the use of the machine.

[0017] The boring machine column device with this U-shaped layout guide rail allows the control lever to be placed in the L-shaped groove on each short bar, so that each short bar can be moved back and forth to clean up the debris at the same time. This makes it convenient for users to clean up the debris in all the mounting grooves.

[0018] The boring machine column device with the U-shaped guide rail can prevent the control rod from moving left or right and falling off when it moves forward and backward by using a limit plate and a limit block. At the same time, it can prevent the control rod from moving too far backward, thereby preventing the T-block from moving too far backward and falling off.

[0019] 6. The boring machine column device with the U-shaped layout guide rail, when each T-block is moved forward off the worktable by the control rod, will connect each slide and each limit bar. Then, when the control rod is released, the T-block and the control rod will move downward due to gravity, thus exposing the mounting slot on the worktable. This will prevent the mounting slot on the worktable from being blocked and affecting the installation of the parts that need to be processed. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings, wherein the same parts are indicated by the same reference numerals. It should be noted that the terms “front”, “rear”, “left”, “right”, “upper” and “lower”, “bottom surface” and “top surface” used in the following description refer to the directions in the drawings, and the terms “inner” and “outer” refer to the directions toward or away from the geometric center of a specific part, respectively.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-7The present invention provides a technical solution: a boring machine column device with a U-shaped layout guide rail, comprising a bed 1, a worktable 3 on the bed 1, a U-shaped column 4 fixedly installed on the right side of the bed 1, a U-shaped guide rail 15 fixedly installed on the inner wall of the U-shaped column 4, two guide rail assemblies a16 on the U-shaped guide rail 15, two crossbars 2 fixedly installed on the two guide rail assemblies a16, connecting blocks 12 on the two crossbars 2, a spindle box 5 fixedly installed on the lower side of the connecting blocks 12, two vertical blocks 14 fixedly installed on each of the two guide rail assemblies a16, and a lead screw 13 threaded through each of the two vertical blocks 14. A housing 6 is fixedly installed on the upper side of column 4. The housing 6 is connected to two lead screws 13. The housing 6 has a rotary starter that can drive the lead screws 13 to rotate back and forth. The lower ends of the two lead screws 13 are connected to brackets 19 through bearings. The brackets 19 are fixedly connected to the U-shaped column 4. A sliding platform 8 is provided on the bed 1. A secondary column 7 is fixedly installed on the sliding platform 8. The secondary column 7 is distributed in a U-shape through guide rails, which enhances the moment of inertia of the U-shaped column 4 and effectively resists the deformation caused by cutting force and vibration. The U-shaped layout can simultaneously withstand radial cutting force, axial load and overturning moment. The stress is dispersed by multi-point support, reducing the risk of local deformation.

[0031] Two guide rail assemblies b9 are connected to the U-shaped guide rail 15. Two support rods 10 are fixedly installed on each guide rail assembly b9. Vertical bars 11 are movably sleeved on each of the four support rods 10, and all four vertical bars 11 are fixedly connected to the spindle box 5. Two reinforcing rods 21 are fixedly installed on the two guide rail assemblies b9. A cylinder 22 is fixedly installed on the rear end of the output shaft of the cylinder 22. A horizontal bar 18 is fixedly installed on the rear side of the horizontal bar 18, and two blocks 20 are fixedly connected to the inner rear wall of the U-shaped column 4. By retracting the output shaft of the cylinder 22, the two guide rail assemblies b9 can be moved back and forth, thereby moving the four support rods 10 back and forth, which in turn moves the spindle box 5 back and forth, allowing for adjustment of the spindle box 5's position. Each mounting slot is movably connected to a T-shaped block 25, and each T-shaped block 25 is fixedly mounted with a movable block 33. Through the T-shaped block 25 and the movable block 33, when too much debris accumulates in the mounting slot on the workbench 3, the user can use the movable block 33 to move the T-shaped block 25 back and forth to clean the internal debris, thus avoiding the long-term accumulation of debris that is difficult to clean and affects use. Each movable block 33 is fixedly mounted with a short strip 36, and each short strip 36 has an L-shaped groove 35. The workbench 3 is equipped with a control rod 26, which is movably connected to each L-shaped groove 35. By placing the control rod 26 in the L-shaped groove 35 on each short strip 36, each short strip 36 can be moved back and forth to clean the debris, making it convenient for the user to clean the debris in all mounting slots.

[0032] Example 2, based on Example 1, such as Figures 5-7 As shown, small pillars 27 are fixedly installed at both ends of the control lever 26. Hemispherical grooves 28 are formed on the sides of the two pillars 27 that are far apart from each other. A ball 29 is movably connected within each hemispherical groove 28. Limiting plates 37 are fixedly installed on both sides of the worktable 3. The sides of the two limiting plates 37 that are close to each other are respectively in contact with the two balls 29. Limiting blocks 30 are fixedly installed on the rear sides of both limiting plates 37. The limiting plates 37, in conjunction with the limiting blocks 30, prevent the control lever 26 from moving left or right and falling off when moving forward or backward. They also prevent the control lever 26 from moving too far backward, thus preventing the T-block 25 from moving too far backward and falling off. Two sliding grooves are formed on each moving block 33. 34. Several sets of small blocks 32 are fixedly installed on the front of the worktable 3. Each small block 32 is fixedly installed with a limit strip 31. Each limit strip 31 is movably connected to each slide 34. Two support plates 23 are fixedly installed on the front of the worktable 3. Two vertical plates 24 are fixedly installed on each of the two support plates 23. When each T-block 25 is moved forward out of the worktable 3 by the control rod 26, each slide 34 and each limit strip 31 will be connected. Then, the control rod 26 is released. Due to gravity, the T-block 25 and the control rod 26 will move downward, thereby exposing the mounting slot on the worktable 3. This will prevent the mounting slot on the worktable from being blocked and affecting the installation of the parts to be processed.

[0033] When in use, the first step is to use U-shaped guide rails to enhance the moment of inertia of the U-shaped column 4, effectively resisting deformation caused by cutting force and vibration. The U-shaped layout can simultaneously withstand radial cutting force, axial load and overturning moment, and disperse stress through multi-point support to reduce the risk of local deformation.

[0034] Step 2: By retracting the output shaft of cylinder 22, the two guide rail assemblies b9 can be moved back and forth, which in turn can move the four support rods 10 back and forth, thus moving the spindle box 5 back and forth, thereby adjusting the position of the spindle box 5.

[0035] Step 3: Using T-block 25 and movable block 33, when too much debris accumulates in the mounting slot on the workbench 3, the user can use movable block 33 to move T-block 25 back and forth. This allows the T-block 25 to be moved back and forth to clean the internal debris, thus avoiding the accumulation of debris over a long period of time, which is difficult to clean and affects the use.

[0036] Step 4: By placing the control lever 26 into the L-shaped groove 35 on each short bar 36, each short bar 36 can be moved back and forth to clean up debris, making it convenient for the user to clean up debris in all the mounting grooves.

[0037] Step 5: By using the limiting plate 37 in conjunction with the limiting block 30, the control rod 26 can be prevented from moving left or right and falling off when it moves back and forth. At the same time, it can prevent the control rod 26 from moving too far backward, thereby preventing the T-shaped block 25 from moving too far backward and falling off.

[0038] Step 6: When each T-block 25 is moved forward out of the worktable 3 by the control lever 26, each slide 34 and each limit bar 31 will be connected. Then release the control lever 26. Due to gravity, the T-block 25 and the control lever 26 will move downward, thereby exposing the mounting slot on the worktable 3. This will prevent the mounting slot on the worktable from being blocked and affecting the installation of the parts that need to be processed.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
