Description

Technical Field

[0001] The present invention relates to the technical field of numerically controlled lathes, and in particular to a rotary automatic numerically controlled lathe and a method for using the same. Background Art

[0002] CNC lathe is one of the most widely used CNC machine tools. It is mainly used for cutting and processing of inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary taper angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads, and can also perform grooving, drilling, reaming, reaming and boring. CNC machine tools automatically process the parts to be processed according to the pre-compiled processing program. The processing route, process parameters, tool motion trajectory, displacement, cutting parameters and auxiliary functions of the parts are compiled into a processing program sheet according to the instruction code and program format specified by the CNC machine tool, and then the contents of this program sheet are recorded on the control medium, and then input into the CNC device of the CNC machine tool, so as to command the machine tool to process the parts.

[0003] In the prior art, the invention patent with patent application number CN201910882946.8 discloses a CNC double-head vertical lathe, which clamps the lower side of the annular workpiece by a clamping block, supports and positions the lower side of the annular workpiece by a rotating plate, and then uses two turning tools on the upper side to turn the inner and outer walls of the annular workpiece, thereby achieving the effect of turning the inner and outer walls of the end of the annular workpiece; however, in specific applications, it is often necessary to turn the other end of the annular workpiece. Before turning the other end of the annular workpiece, it is first necessary to release the clamping of the annular workpiece, flip the annular workpiece, and then clamp and position the annular workpiece, and finally cut the other end. When the annular workpiece is disassembled and flipped, it is also necessary to clean the waste chips attached to the outside of the annular workpiece to avoid the waste chips affecting subsequent cutting work, but this operation method is relatively cumbersome and affects the processing efficiency of the annular workpiece.

[0020] The present invention also discloses a method for using a rotary automatic numerically controlled lathe, comprising the following steps:

[0021] S1: The annular workpiece to be processed is placed on the rotating seat, and the upper rotating plate is pressed by the elastic telescopic rod to move relative to the lower rotating plate, and the elastic telescopic rod is deformed to buffer and unload the lowering of the annular workpiece;

[0022] S2: Then the staff controls the clamping mechanism to work, the output shaft of the second motor drives the screw to rotate, the first sleeve moves along the axial direction of the screw, and the first sleeve drives the clamping plate to move through the connecting plate and the sleeve, so that the clamping plate clamps the annular workpiece on the rotating seat;

[0023] When the first sleeve moves, it drives the elastic telescopic plug rod on the connecting plate to move, so that the elastic telescopic plug rod is inserted into the plug hole of the upper rotating plate, thereby fixing the height position of the upper rotating plate at this time;

[0024] S3: Then the staff controls the working of the processing part to make the first hydraulic cylinder and the second hydraulic cylinder cooperate until the processing tool holder is placed on the upper side of the annular workpiece and abuts against the upper side wall of the annular workpiece. At this time, the first motor is controlled to operate, and the first motor drives the annular workpiece clamped on the rotating seat to rotate, thereby realizing the cutting work of the annular workpiece;

[0025] S4: After the cutting of the upper end of the annular workpiece is completed, the staff controls the third motor to operate, and the output shaft of the third motor drives the sleeve to rotate through the driving rod, so that the sleeve rotates the annular workpiece clamped by the clamping plate;

[0026] S5: When the output shaft of the third motor rotates, the outer incomplete bevel gear meshes with the auxiliary bevel gear at the end of the lifting rod for transmission, and the lifting rod drives the reciprocating screw to rotate. When the reciprocating screw rotates, the second sleeve first moves upward along its axial direction, and then automatically moves downward along its track groove after moving to the upper end of the reciprocating screw, so that the second sleeve drives the clamped annular workpiece to reciprocate up and down through the connecting frame, and the debris generated during the processing of the outer side of the annular workpiece is shaken off;

[0027] When the reciprocating screw rod rotates, it drives the winding rod to rotate, the first drum on the winding rod winds up the first pull rope, and the second drum winds up the second pull rope. When the second pull rope is wound up, it first drives the slider to move down in the slide groove, and the second elastic element is compressed. When the first pull rope is wound up, it drives the elastic telescopic rod to move out of the insertion hole through the connecting plate. After the elastic telescopic rod moves out of the insertion hole, the first pull rope pulls down the upper rotating plate through the slider, and the elastic telescopic rod is further compressed, so that the upper rotating plate moves down, so as not to hinder the flipping of the annular workpiece.

[0028] S6: After the third motor drives the upper and lower ends of the annular workpiece to exchange positions through the clamping plate, the incomplete bevel gear is no longer meshed with the auxiliary bevel gear, the winding rod no longer pulls the connecting plate and the upper turn plate, and the elastic telescopic rod pushes the upper turn plate to move up, so that the top surface of the upper turn plate abuts against the bottom surface of the annular workpiece, and the elastic telescopic rod is reinserted into the socket, and the height of the upper turn plate is re-fixed at this time, so that the upper turn plate supports and limits the bottom of the annular workpiece, and then the processing part cuts the upper end of the annular workpiece.

[0029] Compared with the prior art, the present invention provides a rotary automatic CNC lathe and a method for using the same, which have the following beneficial effects:

[0030] 1. The rotary automatic CNC lathe and the use method thereof, through the working of the clamping mechanism in cooperation with the rotating mechanism, can quickly flip the circular workpiece on the basis of stably supporting and clamping the circular workpiece, and then perform cutting processing on both ends thereof, thereby improving the processing efficiency of the circular workpiece. During the flipping of the circular workpiece, the shaking component automatically works to automatically clean the debris on the surface of the circular workpiece, thereby reducing the workload of the staff and ensuring the processing quality of the circular workpiece.

[0031] 2. The rotary automatic CNC lathe and the method of using the same are such that when the rotary mechanism drives the annular workpiece to flip, the upper turn plate is no longer restricted by the elastic telescopic rod and automatically moves downward under the pulling force of the second pull rope, thereby preventing the upper turn plate from obstructing the flipped annular workpiece, thereby allowing the annular workpiece to be processed stably.

[0032] 3. The rotary automatic CNC lathe and the method for using the same are as follows: when the incomplete bevel gear is not meshed with the auxiliary bevel gear, the winding rod will no longer pull the connecting plate and the upper turn plate, and the elastic telescopic rod pushes the upper turn plate to move upward. During the upward movement of the upper turn plate, the extrusion inclined surface of the end of the elastic telescopic plug rod is pushed, so that the elastic telescopic plug rod avoids the upward movement of the upper turn plate until the top surface of the upper turn plate abuts against the bottom surface of the annular workpiece, and then the elastic telescopic plug rod is reinserted into the insertion hole under the pulling of the first elastic element, and the height of the upper turn plate is re-fixed at this time, so that the upper turn plate supports and limits the bottom of the annular workpiece, effectively preventing the annular workpiece from being forced to move downward during cutting, thereby ensuring the processing quality of the annular workpiece.

[0033] 4. The rotary automatic CNC lathe and the method for using the same are configured to arrange a plurality of elastic telescopic rods at unequal intervals on the connecting plate, so that at least one elastic telescopic rod is always aligned and plugged into the plug hole, and the remaining elastic telescopic rods that are not aligned with the plug hole are automatically retracted, thereby ensuring that the upper rotating plate stably supports the annular workpiece.

[0055] Specifically, the annular workpiece to be processed is placed on the rotating seat 2, and the upper rotating plate 203 is pressed by the elastic telescopic rod 202 to move relative to the lower rotating plate 201. The elastic telescopic rod 202 is deformed to buffer the lowering of the annular workpiece. Then the staff controls the clamping mechanism to make the clamping assembly drive the clamping plate 3 to clamp and position the annular workpiece placed on the rotating seat 2, and then the upper end of the annular workpiece is cut by the processing part. After the cutting of the upper end of the annular workpiece is completed, the clamping mechanism cooperates with the rotating mechanism to quickly flip the annular workpiece on the basis of stable support and clamping of the annular workpiece, and then cut both ends of the annular workpiece, thereby improving the processing efficiency of the annular workpiece, and during the flipping of the annular workpiece, the shaking assembly automatically works to automatically clean the debris on the surface of the annular workpiece, thereby reducing the workload of the staff and ensuring the processing quality of the annular workpiece.

[0056] Example 2: Reference Figure 1 , Figure 4 , Figure 7 , Fig. 9 and Fig.10 , a rotary automatic CNC lathe, based on Example 1, further, the clamping assembly includes a mounting frame 4 fixedly mounted on the rotating seat 2, a second motor 401 is fixedly mounted on the mounting frame 4, a screw 402 connected to the output shaft of the second motor 401 is rotatably connected to the mounting frame 4, a first sleeve 403 is threadedly connected to the screw 402, a connecting plate 404 is provided on the first sleeve 403, a sleeve 405 is rotatably connected to the connecting plate 404, and one end of the sleeve 405 away from the connecting plate 404 is slidably connected to the clamping plate 3.

[0057] Specifically, when the clamping assembly is working, the second motor 401 is controlled to operate, the output shaft of the second motor 401 drives the screw 402 to rotate, the first sleeve 403 moves axially along the screw 402, and the first sleeve 403 drives the clamping plate 3 to move through the connecting plate 404 and the sleeve 405, so that the clamping plate 3 clamps the annular workpiece on the rotating seat 2.

[0058] Example 3: Reference Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 , a rotary automated CNC lathe, based on Example 2, further, a fixed plate 5 is fixedly provided on the lower side of the first sleeve 403, a sliding rod 501 is slidably connected to the fixed plate 5, a connecting plate 6 is fixedly provided at one end of the sliding rod 501, a first elastic element 502 is sleeved on the outer side of the sliding rod 501, and two ends thereof are respectively connected to the fixed plate 5 and the connecting plate 6, the first elastic element 502 is configured as a spring, and a plurality of elastic telescopic plug rods 601 distributed at unequal intervals are provided on the connecting plate 6, a socket 2031 matching the elastic telescopic plug rod 601 is provided on the upper rotating plate 203, and an extrusion slope is provided on the lower side of the end of the elastic telescopic plug rod 601.

[0059] Specifically, when the first sleeve 403 moves axially along the screw rod 402, the first sleeve 403 drives the elastic telescopic rod 601 on the connecting plate 6 to move toward the upper rotating plate 203, so that the elastic telescopic rod 601 is inserted into the insertion hole 2031, and the position of the upper rotating plate 203 at this time is fixed, thereby effectively supporting the placed annular workpiece, avoiding the downward movement of the upper end of the annular workpiece during cutting force, and affecting the processing quality of the annular workpiece; and multiple elastic telescopic rods 601 are unequally spaced on the connecting plate 6, so that there is always at least one elastic telescopic rod 601 aligned with the insertion hole 2031, and the remaining elastic telescopic rods 601 that are not aligned with the insertion hole 2031 automatically shrink, thereby ensuring the stable support state of the upper rotating plate 203 for the annular workpiece.

[0060] Example 4: Reference Figure 1 , Figure 4 , Figure 5 , Figure 7 and Fig. 9 , a rotary automated CNC lathe, based on Example 3, further, the rotating mechanism includes a connecting frame 7 arranged on the mounting frame 4, a third motor 701 is fixed on the connecting frame 7, and the output shaft of the third motor 701 is connected to a driving rod 702 connected to the sleeve 405.

[0061] Specifically, when the rotating mechanism is working, the third motor 701 is controlled to operate, so that the output shaft of the third motor 701 drives the driving rod 702 to rotate, and the driving rod 702 drives the sleeve 405 slidably connected to it to rotate through the guide bar, thereby rotating the annular workpiece clamped by the clamping plate 3 at the end of the sleeve 405.

[0062] Example 5: Reference Figure 1 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 , a rotary automated CNC lathe, based on Example 4, further, the shaking assembly includes a second support plate 11 fixedly mounted on the mounting frame 4, a reciprocating screw 111 is rotatably connected to the second support plate 11, a lifting rod 112 rotatably connected to the connecting frame 7 is slidably connected inside the reciprocating screw 111, a secondary bevel gear 1121 is arranged on the top of the lifting rod 112, a first support plate 8 rotatably connected to the secondary bevel gear 1121 is fixedly mounted on the connecting frame 7, an incomplete bevel gear 7011 meshing with the secondary bevel gear 1121 is connected to the output shaft of the third motor 701, a second sleeve 113 is threadedly connected to the outer side of the reciprocating screw 111, and the second sleeve 113 is fixedly connected to the connecting frame 7.

[0063] Furthermore, telescopic tubes 12 are provided between the mounting frame 4 and the connecting frame 7 and between the connecting plate 404 and the first sleeve 403 .

[0064] Specifically, when the output shaft of the third motor 701 rotates, the outer incomplete bevel gear 7011 meshes with the auxiliary bevel gear 1121 at the end of the lifting rod 112 for transmission. The incomplete bevel gear 7011 and the auxiliary bevel gear 1121 have different numbers of teeth, so that the incomplete bevel gear 7011 rotates half a circle, and the auxiliary bevel gear 1121 can drive the auxiliary bevel gear 1121 to rotate multiple circles. The lifting rod 112 drives the reciprocating screw rod 111 to rotate. When the reciprocating screw rod 111 rotates, the second sleeve 113 first moves upward along its axial direction, so that the clamping plate 3 drives the annular workpiece to move upward when flipping. After moving to the upper end of the reciprocating screw rod 111, the second sleeve 113 automatically moves downward along its track groove, so that the second sleeve 113 drives the clamped annular workpiece to shake back and forth up and down through the connecting frame 7, and shakes off the debris generated during the processing of the outer side of the annular workpiece, so as to avoid affecting the cutting operation of the annular workpiece by the processing part.

[0065] Example 6: Reference Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.11, a rotary automatic CNC lathe, on the basis of Example 5, further, a winding rod 9 is fixedly provided at the bottom of the reciprocating screw rod 111, and a first reel 901 is provided on the winding rod 9, and a first pull rope 9011 is wound around the first reel 901 and connected, and the end of the first pull rope 9011 away from the first reel 901 is connected to the connecting plate 6, and a second reel 902 is also provided on the winding rod 9, and a second pull rope 9021 is wound around the second reel 902 and connected, and the end of the second pull rope 9021 away from the second reel 902 passes through the mounting frame 4 and the upper rotating plate 203 and is connected to the slider 1001, and a slide groove 10 for the slider 1001 to slide is opened on the upper rotating plate 203, and a second elastic element 1002 is provided between the inner wall of the slide groove 10 and the slider 1001, and the second elastic element 1002 is configured as a spring.

[0066] Specifically, when the shaking assembly is working, the reciprocating screw rod 111 rotates, and the rotation of the reciprocating screw rod 111 drives the winding rod 9 to rotate. The first drum 901 on the winding rod 9 winds up the first pull rope 9011, and the second drum 902 winds up the second pull rope 9021. When the second pull rope 9021 is wound up, it first drives the slider 1001 to move down in the slide groove 10, and the second elastic element 1002 is compressed. When the first pull rope 9011 is wound up, it drives the elastic telescopic plug rod 601 to move out of the insertion hole 2031 through the connecting plate 6. After the elastic telescopic plug rod 601 moves out of the insertion hole 2031, the first pull rope 9011 pulls down the upper rotating plate 203 through the slider 1001, and the elastic telescopic rod 202 is further compressed, so that the upper rotating plate 2 03 moves downward without hindering the flipping of the annular workpiece. After the third motor 701 drives the upper and lower ends of the annular workpiece to exchange positions through the clamping plate 3, the incomplete bevel gear 7011 is no longer engaged with the secondary bevel gear 1121, and the winding rod 9 no longer pulls the connecting plate 6 and the upper rotating plate 203. The elastic telescopic rod 202 pushes the upper rotating plate 203 to move upward, so that the top surface of the upper rotating plate 203 abuts against the bottom surface of the annular workpiece, and the elastic telescopic plug 601 is reset and reinserted into the plug hole 2031, and the height of the upper rotating plate 203 is re-fixed at this time, so that the upper rotating plate 203 supports and limits the bottom of the annular workpiece, effectively preventing the annular workpiece from being forced to move downward during cutting, thereby ensuring the processing quality of the annular workpiece.

[0067] Example 7: Reference Figure 1 and Figure 4 , a rotary automatic CNC lathe, based on Example 6, further, the processing part includes a first hydraulic cylinder 13 fixed on the frame 1, the plunger rod of the first hydraulic cylinder 13 is connected to a moving seat 131 slidably connected to the frame 1, a second hydraulic cylinder 132 is fixed on the moving seat 131, and the plunger rod of the second hydraulic cylinder 132 is connected to a processing tool seat 133.

[0068] Specifically, when the processing part is working, the first hydraulic cylinder 13 and the second hydraulic cylinder 132 cooperate until the processing tool seat 133 is placed on the upper side of the annular workpiece and abuts against the upper side wall of the annular workpiece. At this time, the first motor 101 is controlled to run, and the first motor 101 drives the annular workpiece clamped on the rotating seat 2 to rotate, thereby realizing the cutting of the annular workpiece.

[0069] The present invention also discloses a method for using a rotary automatic numerically controlled lathe, comprising the following steps:

[0070] S1: The annular workpiece to be processed is placed on the rotating seat 2, and the upper rotating plate 203 is pressed by the elastic telescopic rod 202 to move relative to the lower rotating plate 201, and the elastic telescopic rod 202 is deformed to buffer and unload the lowering of the annular workpiece;

[0071] S2: Then the staff controls the clamping mechanism to work, the output shaft of the second motor 401 drives the screw 402 to rotate, the first sleeve 403 moves along the axial direction of the screw 402, and the first sleeve 403 drives the clamping plate 3 to move through the connecting plate 404 and the sleeve 405, so that the clamping plate 3 clamps the annular workpiece on the rotating seat 2;

[0072] When the first sleeve 403 moves, it drives the elastic telescopic rod 601 on the connecting plate 6 to move, so that the elastic telescopic rod 601 is inserted into the insertion hole 2031 of the upper rotating plate 203, and the height position of the upper rotating plate 203 is fixed at this time;

[0073] S3: Then the staff controls the working of the processing part to make the first hydraulic cylinder 13 and the second hydraulic cylinder 132 cooperate until the processing tool holder 133 is placed on the upper side of the annular workpiece and abuts against the upper side wall of the annular workpiece. At this time, the first motor 101 is controlled to operate, and the first motor 101 drives the annular workpiece clamped on the rotating seat 2 to rotate, thereby realizing the cutting work of the annular workpiece;

[0074] S4: After the cutting of the upper end of the annular workpiece is completed, the staff controls the third motor 701 to operate, and the output shaft of the third motor 701 drives the sleeve 405 to rotate through the driving rod 702, so that the sleeve 405 rotates the annular workpiece clamped by the clamping plate 3;

[0075] S5: When the output shaft of the third motor 701 rotates, the outer incomplete bevel gear 7011 meshes with the auxiliary bevel gear 1121 at the end of the lifting rod 112 for transmission, and the lifting rod 112 drives the reciprocating screw 111 to rotate. When the reciprocating screw 111 rotates, the second sleeve 113 first moves upward along its axial direction, and then automatically moves downward along its track groove after moving to the upper end of the reciprocating screw 111, so that the second sleeve 113 drives the clamped annular workpiece to reciprocate up and down through the connecting frame 7, and the debris generated during the processing of the outer side of the annular workpiece is shaken off;

[0076] When the reciprocating screw rod 111 rotates, it drives the winding rod 9 to rotate, the first drum 901 on the winding rod 9 reels the first pull rope 9011, and the second drum 902 reels the second pull rope 9021. When the second pull rope 9021 is reeled in, it first drives the slider 1001 to move downward in the slide groove 10, and the second elastic element 1002 is compressed. When the first pull rope 9011 is reeled in, it drives the elastic telescopic plug rod 601 to move out of the insertion hole 2031 through the connecting plate 6. After the elastic telescopic plug rod 601 moves out of the insertion hole 2031, the first pull rope 9011 pulls down the upper rotating plate 203 through the slider 1001, and the elastic telescopic rod 202 is further compressed, so that the upper rotating plate 203 moves downward, so as not to hinder the flipping of the annular workpiece.

[0077] S6: After the third motor 701 drives the upper and lower ends of the annular workpiece to exchange positions through the clamping plate 3, the incomplete bevel gear 7011 is no longer meshed with the secondary bevel gear 1121, and the winding rod 9 no longer pulls the connecting plate 6 and the upper turn plate 203. The elastic telescopic rod 202 pushes the upper turn plate 203 to move upward, so that the top surface of the upper turn plate 203 abuts against the bottom surface of the annular workpiece, and the elastic telescopic rod 601 is reinserted into the socket 2031, and the height of the upper turn plate 203 is re-fixed at this time, so that the upper turn plate 203 supports and limits the bottom of the annular workpiece, and then the processing part cuts the upper end of the annular workpiece.
