[0002] The high-speed drill lathe combined machine tool is a highly integrated numerical control machining equipment.

[0010] Further, the rotating assembly comprises a rotating cylinder rotatingly connected to the interior of the base, the interior of the rotating cylinder is arranged in a hollow manner, and the inner wall of the rotating cylinder is fixedly connected with three V-shaped rings. The outer surface of the three V-shaped rings is rotatingly connected with an inner cylinder, the inner wall of the inner cylinder is fixedly connected with a plurality of elastic plates, and the outer surface of the inner cylinder is provided with three V-shaped grooves. The outer surface of the rotating cylinder is fixedly connected with the ends of the two curved springs away from the base.

[0011] Further, the elastic assembly comprises an elastic sleeve fixedly connected to the interior of the rotating cylinder, the elastic sleeve is made of elastic material, and a plurality of supporting rods are fixedly connected to the side of the elastic sleeve close to the inner cylinder. The plurality of supporting rods are arranged in an equidistant manner 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 rotatingly connected with rolling balls, and the rolling balls are rotatingly penetrated through the outer wall of the V-shaped ring.

[0012] Further, the two elastic semicircular sheets are rotatingly connected to the top of the rotating cylinder. The bearing assembly comprises short rods rotatingly connected to the top of the elastic semicircular sheets, and the outer surface of the two short rods is slidingly connected with a hollow circular ring.

[0013] Further, the hollow circular ring is in communication with the interior of the rotating cylinder through the hose, a plurality of tapered holes are arranged in the side wall of the circular ring disc, and a sealing ring is fixedly connected to the outer surface of the circular ring disc. The hollow circular ring is fixedly connected with an L-shaped plate on one side close to the spring rod, and the L-shaped plate is slidably connected to the side wall of the base.

[0014] The present application has the following advantages: 1、The present application, when the rotating cylinder rotates and stretches the two curved springs, the contraction elastic potential generated by the two curved springs after being stretched will cover the surface of the rotating cylinder while generating a pulling force in the direction of the inner wall of the base, thereby enabling the rotating cylinder to slide in the opposite direction when the drill bit deflects and vibrates, limiting the vibration and deflection amplitude of the drill bit when rotating at high speed, thereby maintaining the perpendicularity of the drill bit when rotating at high speed and drilling, thereby reducing the possibility of breaking or affecting the hole forming when drilling due to vibration generated during drilling, reducing hole position deviation during drilling, improving processing accuracy and perpendicularity of the drill bit during drilling, and improving processing efficiency during processing.

[0015] 2、The present application, when the sliding speed of the circular ring disc slows down, the reset speed of the rotating cylinder is blocked, thereby enabling the inner cylinder to rotate and reset when driven by the drill bit, and a gap appears between the inner cylinder and the rotating cylinder, causing the rotating cylinder to reset quickly under the pulling of the curved spring, which reduces the difficulty of limiting the position of the drill bit after the rotating cylinder resets, causing the drill bit to vibrate again when rotating at high speed, ensuring the stability of the drill bit during high-speed rotation and reset, improving the stability of the drill bit during high-speed rotation, and improving the drilling efficiency of the drill bit.

[0016] 3、The present application, by filling the gap between the two with a plurality of elastic plates, can reduce the gap between the two due to sliding friction between the V-shaped groove and the V-shaped ring during long-term rotation of the inner cylinder, reduce excessive wear between the V-shaped ring and the V-shaped groove, and ensure the stability of the position of the drill bit limited by the rotating cylinder through the inner cylinder, while improving the continuity of the position limitation of the rotating cylinder during long-term rotation of the drill bit, further improving the continuity and stability of the rotating cylinder.

[0017] 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.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] The two elastic semicircular sheets 301 are rotationally connected to the top of the rotating cylinder 221; The bearing assembly 31 comprises a short rod 311 rotationally connected to the top of the elastic semicircular sheet 301, the outer surface of the two short rods 311 is slidingly connected with a hollow circular ring 312; The top of the two short rods 311 inside the hollow circular ring 312 is fixedly connected with a circular ring disc 313, the bottom of the hollow circular ring 312 is fixedly connected with a hose 314, the end of the hose 314 away from the hollow circular ring 312 is slidingly penetrated to the side wall of the elastic sleeve 231, since the top of the elastic semicircular sheet 301 is connected with the short rod 311, and the short rod 311 cannot rotate after being limited by the hollow circular ring 312, when the rotating cylinder 221 drives the bottom of the two elastic semicircular sheets 301 to rotate, the rotating cylinder 221 will push the short rod 311 to slide upward during the rotation through the elastic semicircular sheet 301.

[0032] The hollow circular ring 312 is in communication with the inside of the rotating cylinder 221 through the hose 314, the side wall of the circular ring disc 313 is provided with a plurality of tapered holes, the outer surface of the circular ring disc 313 is fixedly connected with a sealing ring; The side of the hollow circular ring 312 close to the spring rod 211 is fixedly connected with an L plate, the bottom of the L plate is fixedly connected with an auxiliary spring, the L plate is slidingly connected to the side wall of the base 212, the bottom of the auxiliary spring is fixedly connected with the side wall of the base 212, at this time, the external gas will enter between the circular ring disc 313 and the hollow circular ring 312 through the large hole diameter of the plurality of tapered holes on the circular ring disc 313 during the upward sliding of the circular ring disc 313, at this time, the hollow circular ring 312 and the circular ring disc 313 will be filled with gas.

[0033] In use, first, the drill bit to be drilled is installed to the inside of the connecting head 112, then the inner cylinder 222 is sleeved on the surface of the drill bit, and the bracket 201 is connected with the output end of the elevator 104, then the workpiece to be processed is placed into the workpiece clamping member 102, and the workpiece is clamped by the workpiece clamping member 102, then whether to start the workpiece clamping member 102 is selected according to the need, when the workpiece clamping member 102 is started, the workpiece clamping member 102 drives the workpiece to rotate, when the workpiece rotates, the worker rotates the turning tool clamping member 101, so that the turning tool clamping member 101 turns the workpiece, when the stabilizing frame 111 is started, the workpiece clamping member 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 when working, then the worker starts the elevator 104 in the process of high-speed rotation of the connecting head 112, the elevator 104 drives the high-speed rotating connecting head 112 to slide downward when working, the high-speed rotating drill bit drills the workpiece when the connecting head 112 slides downward, thereby achieving the purpose of combined processing of the workpiece.

[0034] When the drill bit is in contact with the workpiece and performs drilling, the high-speed rotating drill bit is prone to produce instantaneous impact when in contact with the workpiece, which causes the drill bit to deviate and vibrate during work. When the drill bit vibrates during processing, the vibration of the drill bit will drive the inner cylinder 222 to rotate. When the inner cylinder 222 rotates, it will rotate towards the inner wall of the rotating cylinder 221 due to the deviation of the drill bit. At this time, the inner cylinder 222 will not be in the center position in the rotating cylinder 221. When the inner cylinder 222 rotates due to the deviation of the drill bit, the plurality of V-shaped grooves on the outer surface of the inner cylinder 222 will be embedded with the plurality of V-shaped rings on the inner wall of the rotating cylinder 221. At this time, the inner cylinder 222, the V-shaped ring and the rotating cylinder 221 will have friction. At the same time, when the drill bit drives the inner cylinder 222 to continue to rotate, the inner cylinder 222 will drive the rotating cylinder 221 to rotate through the friction between the plurality of V-shaped rings and the rotating cylinder 221. When the rotating cylinder 221 rotates, it will stretch the two curved springs 213 connected. Since the surface of the rotating cylinder 221 is circular, the stretching direction of the two curved springs 213 by the rotating cylinder 221 will have a certain arc. At the same time, the curved spring 213 will be attached to the arc surface of the rotating cylinder 221 when stretched. At the same time, when the rotating cylinder 221 rotates and stretches the two curved springs 213, the contraction elastic potential generated by the two curved springs 213 after being stretched will cover the surface of the rotating cylinder 221 while generating a pulling force on the inner wall of the base 212. In this way, the rotating cylinder 221 can slide in the opposite direction when the drill bit deviates and vibrates, and the vibration amplitude of the drill bit when it rotates at high speed can be limited. In this way, the perpendicularity of the drill bit when it rotates at high speed and drills can be maintained, thereby reducing the breaking of the drill bit when it drills at high speed due to vibration during work, and reducing the hole deviation during drilling. At the same time, the processing precision during drilling and the perpendicularity of the drill bit during drilling are improved, and the processing efficiency during processing is improved.

[0035] When the inner cylinder 222 is embedded with the V-shaped rings and the inside of 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 bottom of the two elastic semicircular sheets 301 to rotate synchronously. Since the top of the elastic semicircular sheet 301 is connected with the short rod 311, and the short rod 311 cannot rotate after being limited by the hollow circular ring 312, when the rotating cylinder 221 drives the bottom of the two elastic semicircular sheets 301 to rotate, the rotating cylinder 221 will push the short rod 311 to slide upward through the elastic semicircular sheet 301 in the process of rotation. When the short rod 311 slides upward, it will push the circular ring disc 313 to slide upward inside the hollow circular ring 312. At this time, the space between the hollow circular ring 312 and the circular ring disc 313 will be filled with gas. Since the direction of vibration of the drill bit when working is uncertain, it will deviate to the left or right while resetting, and the drill bit will appear reciprocating motion of deviation and reset when working. When the drill bit deviates, it will drive the inner cylinder 222 to rotate and stretch the curved spring 213 through friction while embedding the inner cylinder 222 with the V-shaped rings. When the drill bit appears reset motion, the rotating cylinder 221 is easy to reset under the action of the elastic potential energy contraction of the two curved springs 213, which drives the rotating cylinder 221 to reset. When the rotating cylinder 221 resets, it will drive the circular ring disc 313 to slide downward through the elastic semicircular sheet 301. Since there is gas inside the hollow circular ring 312, when the circular ring disc 313 slides downward, it will squeeze the gas existing inside the hollow circular ring 312. At this time, a very small part of the gas will be discharged outward through the tapered hole, while more existing gas will provide an opposite resistance to the circular ring disc 313 in the process of the circular ring disc 313 sliding downward, thereby blocking the downward sliding speed of the circular ring disc 313. When the downward sliding speed of the circular ring disc 313 slows down, it will block the reset speed of the rotating cylinder 221, thereby enabling the inner cylinder 222 to rotate and reset when driven by the drill bit. Due to the gap between the inner cylinder 222 and the rotating cylinder 221, the rotating cylinder 221 will quickly reset under the pulling of the curved spring 213. By slowing down the reset speed of the rotating cylinder 221, it can reduce the difficulty of limiting the position of the drill bit after the rotating cylinder 221 resets in the process of the drill bit vibrating and deviating and resetting, thereby reducing the secondary vibration of the drill bit when rotating at high speed, ensuring the stability of the drill bit during high-speed rotation, improving the stability of the drill bit during high-speed rotation, and improving the drilling efficiency of the drill bit.

[0036] When the inner cylinder 222 is embedded with the V-shaped ring along with the deflection and vibration of the drill bit, the inner wall of the V-shaped groove on the outer surface of the inner cylinder 222 will be in contact with the surface of the rolling ball 233. When the inner wall of the V-shaped groove is in contact with the surface of the rolling ball 233, the elastic plate 223 can fill the gap between the V-shaped groove and the V-shaped ring. Since the V-shaped groove on the surface of the inner cylinder 222 is embedded with the V-shaped ring, the inner cylinder 222 will also rotate with the drill bit. By filling the gap between the two with the elastic plate 223, the sliding friction between the V-shaped groove and the V-shaped ring during the long-time rotation of the inner cylinder 222 can be reduced, so that the gap between the two will not increase due to continuous friction, and the excessive wear between the V-shaped ring and the V-shaped groove can be reduced, so that the restriction of the rotating cylinder 221 on the drill bit will not be invalid, and the inner cylinder 222 will not shake in the rotating cylinder 221. The stability of the position restriction of the rotating cylinder 221 on the drill bit by the inner cylinder 222 is ensured, and the continuity of the position restriction of the rotating cylinder 221 during the long-time rotation of the drill bit is improved, and the continuity and stability of the rotating cylinder 221 are further improved.

[0037] When the drill bit is reset after shaking and deflection, the downward sliding of the circular ring disc 313 will squeeze the gas inside the hollow circular ring 312. When the gas is squeezed by the circular ring disc 313, part of the gas will enter between the elastic sleeve 231 on the outer surface of the support rod 232 and the rotating cylinder 221 through the hose 314 under the squeezing of the circular ring disc 313. Since the elastic sleeve 231 is elastic, when the gas enters between the elastic sleeve 231 and the inner cylinder 222, the arc position in the middle of the elastic sleeve 231 will shrink and deform in the direction away from the support rod 232 under the entry of the gas. When the elastic sleeve 231 deforms under the pushing of the gas, the elastic sleeve 231 will drive the support rod 232 and the rolling ball 233 to separate. At this time, the rolling ball 233 can rotate at the V-shaped ring, so that the V-shaped groove on the surface of the inner cylinder 222 can form rolling friction with the rolling ball 233 when the rotating cylinder 221 is shaken and deflected by the drill bit. When the drill bit is reset, the V-shaped groove on the surface of the inner cylinder 222 and the V-shaped ring will cause the inner cylinder 222 and the rotating cylinder 221 to accelerate the reset of the rotating cylinder 221, so that the gas inside the hollow circular ring 312 cannot slow down the reset speed of the circular ring disc 313, further enhancing the stability of the reset speed of the rotating cylinder 221 by the circular ring disc 313, further enhancing the restriction efficiency when the drill bit is shaken and deflected, and improving the working efficiency and machining precision of the drill bit during work.

[0038] When the inner cylinder 222 is sleeved on the surface of the drill bit, the elastic plate 223 can tightly wrap the surface of the drill bit and the recesses on the surface, and rotate with the drill bit along the circular axis. The surface of the drill bit does not limit the up-and-down sliding of the inner cylinder 222 on the surface of the drill bit. When the bottom of the base 212 is in contact with the workpiece, the drill bit continues to process downward, so that the base 212 and the inner cylinder 222 slide upward under the reaction force of the workpiece, thereby not affecting the drilling depth of the drill bit.
