Abstract

This utility model provides a horizontal deep hole drilling machine, including a machine base, a column, a horizontal milling and drilling mechanism, and a rotary table. The horizontal deep hole drilling machine provided by this utility model, by setting and connecting the milling spindle and the drilling spindle laterally, allows the drilling spindle to move left and right along the first transverse guide rail on the milling spindle. This lowers the overall center of gravity of the machine tool and increases the movable range of the drilling spindle, thereby improving the drilling depth and drilling accuracy.

Description

[0022] like Figure 1The diagram shown is a structural schematic of an embodiment of the horizontal deep hole drilling machine tool provided by this utility model. The horizontal deep hole drilling machine tool provided by this utility model mainly includes functional structures such as a machine tool base 10, a column 20, a horizontal milling and drilling mechanism 30, and a rotary table 40. The machine tool base 10 provides an installation platform for the other functional structures in the machine tool, mainly serving a load-bearing and supporting function. Milling operations can be performed on the workpiece by installing a milling cutter on the horizontal milling and drilling mechanism 30, and drilling operations can be performed on the workpiece by installing a drilling tool on the horizontal milling and drilling mechanism 30. The machine tool base 10 in this utility model has an overall L-shaped structure, including a horizontal first base structure 101 and a vertical second base structure 102. The column 20 is vertically installed on the first base structure 101, and the horizontal milling and drilling mechanism 30 is horizontally installed on the column 20, with the horizontal milling and drilling mechanism 30 arranged parallel to the machine tool base 10. The horizontal milling and drilling mechanism can perform milling and drilling on workpieces. By aligning the milling and drilling mechanism horizontally (parallel to the horizontal direction), it avoids instability caused by a high overall machine height. Furthermore, the horizontal alignment increases the lateral movement range of the milling and drilling mechanism, thereby increasing the drilling depth. In this invention, the rotary table 40 is mounted on the second base structure. The workpiece to be processed can be mounted and fixed on the rotary table 40. The horizontal milling and drilling mechanism 30 is controlled to move left and right to process the workpiece. The workpiece can rotate on the rotary table 40 to change its contact position with the horizontal milling and drilling mechanism 30, allowing for processing of different positions on the workpiece by controlling the horizontal milling and drilling mechanism 30.

[0023] Please continue to refer to this. Figure 1 The surface of the column 20 has a first vertical guide rail. The horizontal milling and drilling mechanism 30 is slidably mounted on the first vertical guide rail on the surface of the column. The horizontal milling and drilling mechanism 30 can move up and down along the extension direction of the first vertical guide rail. Specifically, as shown... Figure 2 The diagram shown is a structural schematic of one embodiment of the horizontal milling and drilling mechanism provided by this utility model. Figure 2In the illustrated embodiment, the horizontal milling and drilling mechanism includes a crossbeam 301 and a gun drill 302. The crossbeam 301 is horizontally mounted on the column 20 and can move up and down along the first vertical guide rail to drive the entire horizontal milling and drilling mechanism 30 to move up and down. The gun drill 302 is arranged parallel to the crossbeam 301, and a first transverse guide rail is formed on the side of the crossbeam 301 near the gun drill 302. The gun drill 302 can move left and right along the extension direction of the first transverse guide rail. This invention improves the drilling depth of the deep hole drilling machine by changing the originally longitudinally arranged gun drill to a transverse arrangement and controlling the transverse left and right movement of the gun drill, while ensuring the normal processing of the workpiece by the horizontal milling and drilling mechanism. In this invention, a second transverse guide rail is formed on the second base structure, and the extension direction of the second transverse guide rail is the same as the extension direction of the first transverse guide rail; the rotary table 40 is slidably mounted on the second transverse guide rail and can move left and right along the second transverse guide rail. The workpiece held on the rotary table can be displaced and rotated under the drive of the rotary table, allowing the horizontal milling and drilling mechanism 30 to process different positions on the workpiece. Specifically, when the workpiece is placed on the rotary table 40, the gun drill 302 can be controlled to move left and right to drill holes of different depths on the workpiece; at the same time, the rotation of the rotary table 40 can also be used to drive the workpiece to rotate, so as to control the gun drill to drill holes of different depths at different positions on the workpiece.

[0024] exist Figure 1 In the illustrated embodiment, the column 20 includes a vertical power mechanism 201, a second transmission shaft 202, and a limiting and fixing mechanism (not shown in the figure). A concave groove is formed on the side of the column 20 near the horizontal milling and drilling mechanism. Both the vertical power mechanism 201 and the second transmission shaft 202 are disposed within the concave groove, with the vertical power mechanism 201 positioned at the top of the column 20. It primarily provides power to control the vertical movement of the horizontal milling and drilling mechanism. The limiting mechanism is fixed to the side of the column 20 near the horizontal milling and drilling mechanism 30 and is positioned near the bottom of the column 20. More specifically, the limiting and fixing mechanism is also disposed within the concave groove and near the bottom of the column 20. One end of the second transmission shaft 202 is connected to the vertical power mechanism 201, and the other end is fixedly connected to the limiting and fixing mechanism. The horizontal milling and drilling mechanism 30 is connected to the second drive shaft 202 to move up and down under the control of the vertical power mechanism 201. The vertically movable distance of the horizontal milling and drilling mechanism 30 is typically the length of the second drive shaft 202. The first vertical guide rail is provided on the protruding part of the concave groove. When the horizontal milling and drilling mechanism 30 moves up and down under the drive of the vertical power mechanism 201, it mainly moves along the extension direction of the first vertical guide rail. In some embodiments, the column itself can also be slidably mounted on the machine tool base to further increase the movable range of the horizontal milling and drilling mechanism, thereby increasing the drilling depth.

[0025] like Figure 3 The image shown is a side view of an embodiment of the horizontal deep hole drilling machine provided by this utility model. Please refer to... Figures 1-3 The horizontal milling and drilling mechanism 30 provided by this utility model also includes a first drive shaft 305 and a milling spindle 306. A mounting groove is also formed on the side of the crossbeam 301 away from the column 20. The first drive shaft 305 is installed horizontally in the mounting groove. The milling spindle 306 is installed on the side of the end of the mounting groove near the end of the rotary table 40, and the milling spindle 306 is protruding from the left side of the crossbeam 301 so that the milling spindle 306 can be used to mill the workpiece fixed on the rotary table 40.

[0026] The horizontal milling and drilling mechanism 30 of this utility model also includes a spindle box 303, which is installed at the end of the crossbeam 301 away from the rotary table 40. The spindle box 303 is slidably mounted on a first transverse guide rail on the surface of the crossbeam 301, and can move left and right along the extension direction of the first transverse guide rail. Specifically, the first drive shaft 305 is mainly used to push the spindle box to move left and right along the extension direction of the first transverse guide rail. A drive motor is installed on the crossbeam 301, and the drive motor is electrically connected to the first drive shaft 305 to drive the first drive shaft 305 and thus drive the spindle box 303 to move left and right. The spindle box 303 contains a drive motor, and one end of the gun drill 302 is electrically connected to the motor in the spindle box 303, so that the motor in the spindle box 303 drives the gun drill 302 to rotate to achieve drilling.

[0027] Please continue to refer to this. Figure 3 The horizontal milling and drilling mechanism 30 provided by this utility model also includes a drilling spindle 307, a guide sleeve 308, and a guide sleeve seat 309. The drilling spindle 307 is fixed to the side of the spindle box 303 near the rotary table 40, and is electrically connected to the spindle box 303. One end of the gun drill 302 is fixedly connected to the drilling spindle 307. When the motor in the spindle box 303 operates, it drives the drilling spindle 307 to rotate, thereby driving the gun drill 302 fixedly connected to the drilling spindle 307 to rotate, so as to drill holes in the workpiece fixed on the rotary table 40 using the gun drill 302. When the spindle box 303 moves left and right along the extension direction of the first transverse guide rail, the drilling spindle can follow the spindle box 303 to move left and right along the first transverse guide rail, and drive the gun drill 302 to also move left and right along the extension direction of the first transverse guide rail, thereby drilling holes of different depths in the workpiece. Figure 3In the illustrated embodiment, one end of the gun drill 302 is fixedly connected to the drilling spindle 307, and the other end of the gun drill 302 passes through the guide sleeve 308. Specifically, the guide sleeve seat 309 is fixed to one end of the crossbeam 301 near the rotary table 40, while the guide sleeve 308 is fixed to the side of the guide sleeve seat 309 near the rotary table 40. The gun drill 302 needs to pass through the guide sleeve seat 309 and the guide sleeve 308 and extend from the guide sleeve 308 to approach the workpiece to be processed. The gun drill 302 passes through the guide sleeve 308, but usually does not directly contact the guide sleeve 308. The guide sleeve 308 provided by this utility model ensures that the gun drill drills along a predetermined axis when the gun drill rotates at high speed, avoiding large vibrations and deviations in the gun drill to ensure drilling accuracy.

[0028] like Figure 4 The diagram shows a structural schematic of one embodiment of the gun drill support frame provided by this utility model. The milling and drilling mechanism 30 provided by this utility model also includes at least one gun drill support frame 310. This is because in actual horizontal deep hole drilling machines, to increase the drilling depth, a longer gun drill is usually used. When the length of the gun drill increases, the rigidity of the gun drill decreases with the increase in length, causing the gun drill to easily bend, deform, or even break during drilling. At least one gun drill support frame 310 in this utility model can support the gun drill 302, preventing the gun drill 302 from bending, deforming, or even breaking during operation. Figure 5 The image shows a side view of the drill support frame provided by this utility model. Specifically, the drill support frame 310 is approximately triangular in structure. The hypotenuse of the drill support frame 310 is inclined relative to the drill 302. One side of the drill support frame 310 is fixedly connected to the side of the crossbeam 301 away from the column. Specifically, a connecting protrusion 3011 protruding from the bottom corner of the drill support frame 310 is formed. The connecting protrusion 3011 is formed towards the crossbeam 301 and is slidably fixed on the crossbeam 301 to fix the drill support frame 310 on the crossbeam 301. The drill support frame 310 can slide left and right along the extension direction of the crossbeam 301 (i.e., the Z-axis direction). The top of the gun drill support frame 310 also has a gun drill limiting groove, in which a special bearing 3012 is disposed. The gun drill support frame 310 also includes an automatic clamping device 3013, which is also disposed on the top of the gun drill support frame 310. This automatic clamping device 3013 can press against the outer ring of the special bearing to clamp and limit the special bearing 3012 within the gun drill limiting groove, preventing movement of the gun drill limiting groove. In some embodiments, the automatic clamping device 3013 can be a clamping cylinder, a clamping hydraulic cylinder, or other devices capable of clamping. The number of automatic clamping devices 3013 in this invention is generally the same as the number of gun drill support frames 310, with one automatic clamping device corresponding to each gun drill support frame 310. Figure 5In the illustrated embodiment, a dedicated bearing 3012 has a through-hole at its center. A rubber sleeve is provided within this through-hole, with a V-shaped inner hole in the center. This V-shaped inner hole opens away from the crossbeam 301. The gun drill 302 passes through the V-shaped inner hole of the rubber sleeve, thus passing through the gun drill support frame 310, and extends to the guide sleeve and the drilling spindle. In some embodiments, multiple gun drill support frames 310 can be provided. These multiple gun drill support frames 310 have identical structures and are all fixedly connected to the side of the crossbeam 301 away from the column. Providing multiple gun drill support frames 310 allows for better support of the gun drill. It should be noted that the gun drill support frame 310 can also slide left and right along the extension direction of the first transverse guide rail, but once the position of the gun drill support frame 310 is determined, it needs to remain fixedly connected to the crossbeam 301.

[0029] Please refer to Figures 1-4 The drilling spindle provided by this utility model also includes a chip box 304, which is installed below the guide sleeve seat 309. Since a large amount of waste chips are generated during the milling and drilling process, it is necessary to use the chip box 304 located below the guide sleeve seat 309 to collect the waste chips and prevent them from accumulating and damaging the parts; the collected waste chips can also be recycled and reused to improve resource utilization.

[0030] like Figure 6 The image shown is a top view of an embodiment of the horizontal deep hole drilling machine tool provided by this utility model. Please refer to... Figures 1-6The horizontal deep hole drilling machine tool of this utility model also includes a saddle 50, which is disposed on the second base structure of the machine tool base, and the rotary table 40 is mounted on the saddle 50. Specifically, the second base structure has a second transverse guide rail extending in the same direction as the first transverse guide rail. The saddle 50 is slidably connected to the second transverse guide rail so that the saddle 50 can move left and right along the extension direction of the second transverse guide rail. When the saddle 50 moves left and right, it can drive the rotary table 40 disposed above the saddle 50 to move left and right as well, thereby controlling the movement of the workpiece placed on the rotary table, and thus using the horizontal milling and drilling mechanism to process the workpiece. The horizontal deep hole drilling machine tool provided by this utility model also includes a cradle mounting base 60, which is mounted above the saddle 50, and the rotary table 40 is mounted on the cradle mounting base 60. Specifically, a third transverse guide rail is formed on the top surface of the saddle 50 away from the machine tool base 10, and the extension direction of the third transverse guide rail is perpendicular to the extension direction of the second transverse guide rail. The cradle mounting base 60 is slidably mounted on the third transverse guide rail and can move back and forth along the third transverse guide rail, driving the rotary table 40 mounted above the cradle mounting base 60 to move back and forth together. The rotary table 40 includes a first rotary base 401, a second rotary base 402, and a third rotary base 403. The first rotary base 401 and the second rotary base 402 are both perpendicular to the machine tool base, while the third rotary base 403 is parallel to the machine tool base. The first rotary base 401 and the second rotary base 402 are arranged opposite each other, and the third rotary base 403 is located between the first rotary base 401 and the second rotary base 402, and is connected to both the first rotary base 401 and the second rotary base 402. The first rotating base 401 and the second rotating base 402 can rotate coaxially along the first rotation axis. When the first rotating base 401 and the second rotating base 402 rotate, they can cause the third rotating base 403 to be displaced. Specifically, when the first rotating base 401 and the second rotating base 402 rotate, the third rotating base 403 can be flipped or rotated accordingly. For example, the third rotating base 403 as a whole can be flipped around the first rotation axis as the rotation center. In other embodiments, the third rotating base 403 can also maintain a position parallel to the horizontal plane and only move up, down, left, and right. That is, the third rotating base 403 as a whole can rotate around the first rotation axis as the rotation center, and the third rotating base 403 maintains an angle parallel to the horizontal plane during rotation, only changing its relative position to the horizontal plane (or saddle 50). The third rotating base 403 itself can also rotate. Specifically, the third rotating base 403 includes a turntable, and the third rotating base 403 can drive the workpiece placed on top to rotate horizontally around the second rotation axis as the rotation center. The first rotation axis is set parallel to the horizontal plane, and the second rotation axis is set perpendicular to the first rotation axis.In this invention, the first rotating base 401 and the second rotating base 402 can drive the third rotating base 403 to rotate or flip as a whole. The third rotating base 403, in turn, can drive the workpiece placed on it to rotate, thereby performing milling and drilling operations at different depths on different positions of the workpiece. The first, second, and third rotating bases of this invention are all driven by servo motors and roller cams; other methods can also be used in other embodiments, which are not limited here. The rotary table 40 can drive the workpiece placed on it to rotate, thereby using the milling spindle and gun drill mounted on the horizontal deep hole drilling machine to drill and process different positions on the workpiece. Thus, processing to greater depths can be achieved with a single clamping, as well as processing of multi-faceted, multi-angle, oblique holes, countersunk holes, and planar milling.

[0031] For the horizontal deep hole drilling machine provided by this utility model, the horizontal milling and drilling mechanism can move up and down along the first vertical guide rail on the column 20. The milling spindle usually only needs to process the surface of the workpiece and does not need to extend into the interior of the workpiece. Therefore, the milling spindle usually only moves up and down. However, the drilling spindle needs to drill holes of different depths in the workpiece. Therefore, it is necessary to increase the horizontal upward movement range of the drilling spindle as much as possible. This utility model increases the drilling depth by setting a first transverse guide rail on the milling spindle, so that the drilling spindle can move left and right along the extension direction of the first transverse guide rail. For the rotary table 40, the rotary table 40 is set above the saddle 50 through the cradle mounting seat 60. A second transverse guide rail is formed above the second machine tool base structure. When the saddle moves left and right along the extension direction of the second transverse guide rail, it can drive the cradle mounting seat 60 to move left and right, thereby driving the rotary table 40 to move left and right. A third transverse guide rail is formed on the top surface of the cradle mounting base 60 near the rotary table. The extension direction of the third transverse guide rail is perpendicular to that of the second transverse guide rail. When the rotary table 40 moves back and forth along the extension direction of the third transverse guide rail, it can drive the workpiece to be processed placed on the rotary table to move back and forth. As for the rotary table 40 itself, under the drive of the first rotary base, the second rotary base, and the third rotary base, the workpiece placed on the rotary table 40 can also be rotated, so that different positions on the workpiece can be processed using the horizontal milling and drilling mechanism. The horizontal deep hole drilling machine provided by this utility model can achieve a depth of more than 600mm, and also has a milling structure to realize milling. When it is necessary to mill countersunk holes, the gun drill and guide sleeve can be removed, the chip box can be pushed to the right by the hydraulic cylinder, and the tool holder and milling cutter can be loaded on the crossbeam 301 to realize milling.

[0032] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0033] The above provides a detailed description of a horizontal deep hole drilling machine provided by the embodiments of this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the technical solutions and core ideas of this utility model. Those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
