Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal cutting machine tools, in particular to a high-speed drill lathe combined machine tool. BACKGROUND

[0002] The high-speed drill lathe combined machine tool is a highly integrated numerical control machining equipment. It is mainly applied to the automobile, aerospace, engineering machinery, mold and other industries, and is used for efficiently and accurately completing turning of the outer circle / end face and drilling, expanding, reaming, tapping and other hole machining processes on disc, shaft and box type parts;

[0003] In the combined machine tool, when the drill bit is rotated at high speed and drills the workpiece, the high-speed rotating drill bit will produce instantaneous impact with the workpiece when the drill bit contacts the workpiece, which can easily cause the drill bit to deviate in position and vibrate when drilling the workpiece. The high-speed rotation of the drill bit can also amplify the vibration amplitude. The vibration generated when the high-speed rotating drill bit is machining the workpiece can easily cause the drill bit to break, and also affect the machining accuracy and the surface quality of the hole forming during drilling, affecting the work efficiency during subsequent machining.

[0024] The outer surface of the rotating cylinder is fixedly connected with the ends of the two curved springs away from the base.

[0025] Further, the elastic assembly includes an elastic sleeve fixedly connected inside the rotating cylinder, the elastic sleeve is made of elastic material, and the side of the elastic sleeve close to the inner cylinder is fixedly connected with a plurality of supporting rods;

[0026] The plurality of supporting rods are arranged equidistantly in three groups, the plurality of groups of supporting rods are arranged in a circular array with the inner cylinder as the center, the ends of the supporting rods away from the elastic sleeve are rotatably connected with rolling balls, and the rolling balls are rotatably arranged through the outer wall of the V-shaped ring.

[0027] Further, the two elastic semicircular pieces are rotatably connected on the top of the rotating cylinder;

[0028] The bearing assembly includes short rods rotatably connected on the top of the elastic semicircular pieces, and the outer surfaces of the two short rods are slidingly connected with a hollow circular ring.

[0029] Inside the hollow ring, two short rods are fixedly connected to the top of a circular disc, and a flexible tube is fixedly connected to the bottom of the hollow ring. The end of the flexible tube away from the hollow ring slides through the side wall of the elastic sleeve.

[0030] Furthermore, the hollow ring is connected to the interior of the rotating cylinder via a flexible hose, and several tapered holes are opened on the side wall of the ring disk. A sealing ring is fixedly connected to the outer surface of the ring disk.

[0031] An L-plate is fixedly connected to the side of the hollow ring near the spring rod. An auxiliary spring is fixedly connected to the bottom of the L-plate. The L-plate is slidably connected to the side wall of the base. The bottom of the auxiliary spring is fixedly connected to the side wall of the base.

[0032] The present invention has the following beneficial effects:

[0033] 1. In this invention, when the rotating cylinder rotates and stretches the two bending springs, the contractile elastic potential energy generated by the two bending springs after being stretched will, while covering the surface of the rotating cylinder, generate a pulling force towards the inner wall of the base. This allows the rotating cylinder to slide in the opposite direction when the drill bit deflects and vibrates, while limiting the vibration amplitude and offset of the drill bit during high-speed rotation. This maintains the perpendicularity of the drill bit during high-speed rotation and drilling, thereby reducing the possibility of the drill bit breaking or affecting the hole formation during drilling due to the vibration generated during the drill bit's operation. It also reduces hole position offset during drilling, improves the machining accuracy and perpendicularity of the drill bit during drilling, and increases the machining efficiency.

[0034] 2. In this invention, when the downward speed of the annular disc is reduced, it will block the reset speed of the rotating cylinder. As a result, when the drill bit drives the inner cylinder to rotate and reset, a gap appears between the inner cylinder and the rotating cylinder, causing the rotating cylinder to reset rapidly under the pull of the bending spring. By reducing the reset speed of the rotating cylinder, the displacement of the rotating cylinder due to the vibration of the drill bit and the difficulty in controlling the position of the drill bit after the rotating cylinder resets can be reduced. This can lead to secondary vibration of the drill bit during high-speed rotation, ensuring the stability of the drill bit during high-speed rotation displacement and reset. This reduces the recurrence of vibration displacement or secondary vibration, improves the stability of the drill bit during high-speed rotation, and increases the drilling efficiency of the drill bit.

[0035] 3. This invention, by filling the gap between the two with several elastic plates, can reduce the increase in gap between the V-groove and V-ring due to sliding friction during long-term rotation of the inner cylinder. This reduces the possibility of excessive wear between the V-ring and V-groove, which could lead to failure of the rotating cylinder in restricting the drill bit or even shaking of the inner cylinder within the rotating cylinder. This ensures the stability of the rotating cylinder's position restriction of the drill bit through the inner cylinder, while also improving the continuity of the rotating cylinder's position restriction during long-term rotation of the drill bit, further enhancing the continuity and stability of the rotating cylinder.

[0036] 4. In this invention, when the elastic sleeve deforms under the push of gas, the elastic sleeve will cause the support rod to disengage from the ball. At this time, the ball can rotate at the V-ring. When the drill bit drives the rotating cylinder to vibrate and deviate for reset, the V-groove on the inner cylinder surface can form rolling friction with the ball. As a result, when the drill bit makes a reset movement, the friction between the V-groove on the inner cylinder surface and the V-ring causes the inner cylinder and the rotating cylinder to accelerate the reset of the rotating cylinder. This makes it difficult for the gas inside the hollow ring to slow down the reset speed of the ring disk. This further enhances the stability of the ring disk in slowing down the reset speed of the rotating cylinder, while further enhancing the limiting efficiency of the drill bit vibration and deviation, thus improving the working efficiency and processing accuracy of the drill bit.

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.

[0051] Please see Figures 1-9 As shown, the present invention is a high-speed drilling and trolley combination machine tool, including a main body 1, a tool holder 101 slidably connected to the top of the main body 1, a workpiece holder 102 rotatably connected to the left inner wall of the main body 1, a length adjustment member 103 slidably connected to the top of the main body 1, and also includes;

[0052] Stabilizing mechanism 2 is installed on the top of the main body 1 to prevent the drill bit from vibrating and shifting during drilling.

[0053] Auxiliary mechanism 3 is installed on the side wall of stabilizing mechanism 2 to provide a compensation gap between stabilizing mechanism 2 and workpiece when the drill bit is working.

[0054] The main body 1 includes a lifting mechanism 104 disposed on the top of the workpiece clamping member 102, and the main body 1 also includes:

[0055] Drilling rig assembly 11 is installed on the top of the main body 1 and is used to drill holes in the workpiece.

[0056] The stabilizing mechanism 2 includes a bracket 201 disposed at the bottom of the drill rig assembly 11, and the stabilizing mechanism 2 also includes:

[0057] Sliding component 21 is installed at the bottom of bracket 201;

[0058] Rotating component 22 is installed inside the sliding component 21;

[0059] The elastic component 23 is installed inside the rotating component 22.

[0060] The auxiliary mechanism 3 includes two elastic semicircular plates 301 disposed on the top of the rotating assembly 22, and the auxiliary mechanism 3 also includes:

[0061] The support component 31 is mounted on top of the two elastic semicircular plates 301.

[0062] The drilling rig assembly 11 includes a stabilizing frame 111 fixedly connected to the top of the main body 1, and a connecting rotor 112 is fixedly connected to the output end of the stabilizing frame 111.

[0063] The lifting mechanism 104 is slidably installed inside the stabilizing frame 111 to drive the connecting rotating head 112 to move up and down when it is working. When the stabilizing frame 111 is started, the workpiece clamping part 102 stops rotating. At the same time, the stabilizing frame 111 will drive the connecting rotating head 112 and the drill bit to rotate at high speed when it is working.

[0064] The bracket 201 is fixedly connected to the output end of the elevator 104;

[0065] The sliding assembly 21 includes a spring rod 211 that slides through the bottom of the bracket 201. The bottom of the spring rod 211 is fixedly connected to a base 212, and the elastic end of the spring rod 211 is fixedly connected to the side wall of the bracket 201.

[0066] Two bending springs 213 are fixedly connected to the back of the base 212. First, the drill bit that needs to be drilled is installed inside the connecting head 112. Then, the inner cylinder 222 is placed on the surface of the drill bit, and the position is selected in the upper middle part of the drill bit surface. At the same time, the bracket 201 is connected to the output end of the elevator 104. Then, the workpiece to be processed is placed in the workpiece clamping part 102.

[0067] The rotating assembly 22 includes a rotating cylinder 221 rotatably connected inside the base 212. The interior of the rotating cylinder 221 is hollow, and three V-shaped rings are fixedly connected to the inner wall of the rotating cylinder 221.

[0068] The outer surfaces of the three V-shaped rings are rotatably connected to the inner cylinder 222, and the inner wall of the inner cylinder 222 is fixedly connected to several elastic plates 223. The outer surface of the inner cylinder 222 is provided with three V-shaped grooves.

[0069] The outer surface of the rotating cylinder 221 is fixedly connected to the end of the two bending springs 213 away from the base 212.

[0070] The elastic component 23 includes an elastic sleeve 231 fixedly connected inside the rotating cylinder 221. The elastic sleeve 231 is made of elastic material, and several support rods 232 are fixedly connected to the side of the elastic sleeve 231 near the inner cylinder 222.

[0071] Several support rods 232 are arranged in groups of three at equal distances. Several groups of support rods 232 are arranged in a circumferential array with the inner cylinder 222 as the center. The end of the support rod 232 away from the elastic sleeve 231 is rotatably connected to a ball 233. The ball 233 rotates through the outer wall of the V-shaped ring. When the cylinder 222 rotates, it will rotate with the offset of the drill bit and move closer to the inner wall of the rotating cylinder 221. At this time, the inner cylinder 222 will not be in the center position inside the rotating cylinder 221. When the inner cylinder 222 rotates with the offset of the drill bit, the multiple V-shaped grooves on the outer surface of the inner cylinder 222 will engage with the multiple V-shaped rings on the inner wall of the rotating cylinder 221.

[0072] Two flexible semicircular plates 301 are rotatably connected to the top of the rotating cylinder 221;

[0073] The support component 31 includes a short rod 311 rotatably connected to the top of the elastic semicircular plate 301, and a hollow ring 312 is slidably connected to the outer surface of the two short rods 311.

[0074] Inside the hollow ring 312, the tops of two short rods 311 are fixedly connected to a circular disc 313, and the bottom of the hollow ring 312 is fixedly connected to a flexible tube 314. The end of the flexible tube 314 away from the hollow ring 312 slides through to the side wall of the elastic sleeve 231. Since the top of the elastic semicircular plate 301 is connected to the short rod 311, and the short rod 311 cannot rotate due to the restriction of the hollow ring 312, when the rotating cylinder 221 drives the bottoms of the two elastic semicircular plates 301 to rotate, the rotating cylinder 221 will push the short rod 311 upward through the elastic semicircular plates 301 during the rotation process.

[0075] The hollow ring 312 is connected to the interior of the rotating cylinder 221 through the hose 314. The side wall of the ring disk 313 has several conical holes, and a sealing ring is fixedly connected to the outer surface of the ring disk 313.

[0076] A hollow ring 312 is fixedly connected to an L-plate on the side near the spring rod 211. An auxiliary spring is fixedly connected to the bottom of the L-plate. The L-plate is slidably connected to the side wall of the base 212. The bottom of the auxiliary spring is fixedly connected to the side wall of the base 212. At this time, the external gas will enter between the ring disk 313 and the hollow ring 312 through the large diameter of several conical holes on the ring disk 313 as the ring disk 313 slides upward. At this time, the space between the hollow ring 312 and the ring disk 313 will be filled with gas.

[0077] In use, first install the drill bit to be drilled into the connecting head 112. Then, fit the inner cylinder 222 onto the surface of the drill bit, selecting a position slightly above the middle of the drill bit surface. Simultaneously, connect the bracket 201 to the output end of the lifting machine 104. Next, place the workpiece to be processed into the workpiece clamping member 102, which will clamp the workpiece. Then, select whether to activate the workpiece clamping member 102 as needed. When the workpiece clamping member 102 is activated, it will drive the workpiece to rotate. While the workpiece is rotating, the operator rotates the cutting tool holder. The tool holder 101 is used to turn the workpiece. When the stabilizing frame 111 is activated, the workpiece holder 102 stops rotating. At the same time, the stabilizing frame 111 drives the connecting head 112 and the drill bit to rotate at high speed. Then, the operator starts the lifting platform 104 while the connecting head 112 is rotating at high speed. When the lifting platform 104 is working, it drives the high-speed rotating connecting head 112 to slide downward. When the connecting head 112 slides downward, the high-speed rotating drill bit drills the workpiece, thereby completing the combined machining of the workpiece.

[0078] Because the high-speed rotation of the drill bit, when in contact with the workpiece and performing drilling, easily generates a momentary impact, causing the drill bit to deviate and vibrate during operation. When the drill bit vibrates during processing, the vibration will drive the inner cylinder 222 to rotate. As the inner cylinder 222 rotates, it will move closer to the inner wall of the rotating cylinder 221 along with the deviation of the drill bit. At this time, the inner cylinder 222 will not be in the center position within the rotating cylinder 221. When the drill bit rotates, the multiple V-grooves on the outer surface of the inner cylinder 222 engage with the multiple V-rings on the inner wall of the rotating cylinder 221. At this time, friction exists between the inner cylinder 222, the V-rings, and the rotating cylinder 221. Simultaneously, as the drill bit drives the inner cylinder 222 to continue rotating, the inner cylinder 222, through the friction between itself, the multiple V-rings, and the rotating cylinder 221, drives the rotating cylinder 221 to rotate. When the rotating cylinder 221 rotates, it stretches the two connected bending springs 213. Because the rotating cylinder 22... 1. With a circular surface, the direction of the tension of the two bending springs 213 on the rotating cylinder 221 will exhibit a certain arc. At the same time, when the bending springs 213 are stretched, they will adhere to the arc surface of the rotating cylinder 221. Simultaneously, when the rotating cylinder 221 rotates and stretches the two bending springs 213, the contractile elastic potential energy generated by the two bending springs 213 after being stretched will cover the surface of the rotating cylinder 221 and generate a pulling force towards the inner wall of the base 212. This allows the rotating cylinder 221 to slide in the opposite direction when the drill bit deflects and vibrates, while limiting the vibration and deviation amplitude of the drill bit during high-speed rotation. This maintains the perpendicularity of the drill bit during high-speed rotation and drilling, thereby reducing the possibility of the drill bit breaking or affecting the hole formation during drilling due to the vibration generated during the drill bit's operation. It also reduces hole position deviation during drilling, improves the machining accuracy and perpendicularity of the drill bit during drilling, and increases machining efficiency.

[0079] When the inner cylinder 222 is fitted with the interior of several V-shaped rings and the rotating cylinder 221, the rotation of the inner cylinder 222 will drive the rotating cylinder 221 to rotate synchronously. When the rotating cylinder 221 rotates, it will drive the bottoms of the two elastic semicircular plates 301 to rotate synchronously. Since the tops of the elastic semicircular plates 301 are connected to the short rod 311, and the short rod 311 cannot rotate due to the restriction of the hollow ring 312, when the rotating cylinder 221 drives the bottoms of the two elastic semicircular plates 301 to rotate, the rotating cylinder 221 will push the short rod 311 upwards through the elastic semicircular plates 301 during the rotation. When the short rod 311 slides upwards, it will push the annular disk 313 to move within the hollow ring 312. As the inner ring slides upward, external gas enters between the circular ring 313 and the hollow ring 312 through the large-diameter holes of several conical holes on the circular ring 313 during the upward sliding process. At this time, the space between the hollow ring 312 and the circular ring 313 is filled with gas. Due to the uncertain vibration direction of the drill bit during operation, it will deviate to the left or right while simultaneously resetting. The drill bit will exhibit reciprocating motion of deviating and resetting during operation. When the drill bit deviates, it will cause the inner cylinder 222 to engage with several V-shaped rings, and simultaneously, through friction, it will rotate the inner cylinder 222 and stretch the bending spring 213. When the drill bit resetting, the rotating cylinder 221 easily... The elastic potential energy of the bending spring 213, under the contraction force, drives the rotating cylinder 221 to reset. When the rotating cylinder 221 resets, it drives the annular disk 313 to slide downwards via the elastic semicircular plate 301. Since the hollow ring 312 contains gas, when the annular disk 313 slides downwards, it compresses the gas inside the hollow ring 312. At this time, a very small portion of the gas will be discharged outwards through the conical hole, while the majority of the gas will provide a reverse resistance to the annular disk 313 during its downward sliding process, thus hindering the downward speed of the annular disk 313. When the downward speed of the annular disk 313 slows down, it will block the reset speed of the rotating cylinder 221, thereby... When the drill bit drives the inner cylinder 222 to rotate and reset, a gap appears between the inner cylinder 222 and the rotating cylinder 221, causing the rotating cylinder 221 to quickly reset under the pull of the bending spring 213. By slowing down the reset speed of the rotating cylinder 221, the position of the drill bit after reset can be reduced due to the vibration and displacement of the rotating cylinder 221 with the drill bit. This reduces the possibility of the rotating cylinder 221 failing to restrain the drill bit's position after reset, which could lead to secondary vibration of the drill bit during high-speed rotation. This ensures the stability of the drill bit during high-speed rotation, displacement, and reset, reduces the recurrence of vibration and displacement or secondary vibration, improves the stability of the drill bit during high-speed rotation, and increases the drilling efficiency of the drill bit.

[0080] When the inner cylinder 222 engages with several V-rings due to the offset and vibration of the drill bit, the inner walls of the multiple V-grooves on the outer surface of the inner cylinder 222 will contact the surfaces of several rolling balls 233. When the inner walls of the V-grooves contact the surfaces of the rolling balls 233, the elastic plates 223 can fill the gaps between the V-grooves and the V-rings. Since the inner cylinder 222 will also rotate with the drill bit when the V-grooves on the surface of the inner cylinder 222 engage with the V-rings, the elastic plates 223 can fill the gaps between them, reducing the impact of the inner cylinder 222 on the drill bit over a long period of time. During rotation, the sliding friction between the V-groove and the V-ring causes the gap between them to increase with continuous friction. This reduces the possibility of excessive wear between the V-ring and the V-groove, which could lead to the failure of the rotating cylinder 221 in restricting the drill bit or even the inner cylinder 222 wobbling inside the rotating cylinder 221. This ensures the stability of the rotating cylinder 221 in restricting the drill bit position through the inner cylinder 222, and also improves the continuity of the rotating cylinder 221 in restricting the position of the drill bit during long-term rotation of the drill bit, further enhancing the continuity and stability of the rotating cylinder 221.

[0081] When the drill bit vibrates and shifts, it resets. The downward sliding of the annular disk 313 compresses the gas inside the hollow annular ring 312. This compression slows the downward movement of the annular disk 313. Some of the gas, under the pressure of the annular disk 313, enters through the hose 314 between the elastic sleeve 231 and the rotating cylinder 221 on the outer surface of the support rod 232. Because the elastic sleeve 231 is elastic, when the gas enters between the elastic sleeve 231 and the inner cylinder 222, the arc-shaped portion of the elastic sleeve 231 contracts and deforms away from the support rod 232. When the elastic sleeve 231 deforms under the pressure of the gas, it causes the support rod 232 to disengage from the ball bearing 233. When the ball 233 rotates at the V-ring, the V-groove on the surface of the inner cylinder 222 can form rolling friction with the ball 233 when the drill bit drives the rotating cylinder 221 to vibrate and deviate for reset. As a result, when the drill bit makes a reset movement, the friction between the V-groove on the surface of the inner cylinder 222 and the V-ring causes the rotating cylinder 221 to reset faster. This makes it difficult for the gas inside the hollow ring 312 to slow down the reset speed of the ring disk 313. This further enhances the stability of the ring disk 313 in slowing down the reset speed of the rotating cylinder 221, and further enhances the limiting efficiency of the drill bit to suppress vibration and deviate, thereby improving the working efficiency and machining accuracy of the drill bit.

[0082] When the inner cylinder 222 is fitted onto the drill bit surface, the elastic plate 223 can tightly wrap around the drill bit surface and the groove on the surface, and rotate with the drill bit as the drill bit rotates. The drill bit surface does not restrict the inner cylinder 222 from sliding up and down on the drill bit surface. When the bottom of the base 212 contacts the workpiece, the drill bit continues to process downwards, which allows the base 212 and the inner cylinder 222 to slide upwards under the reaction force of the workpiece, thus not affecting the drilling depth of the drill bit.
