Description

Technical Field

[0001] The invention relates to the technical field of CNC lathes, and in particular to a multi-head vertical CNC lathe and a use method thereof. Background Art

[0002] CNC lathe is a high-precision, high-efficiency automated machine tool that can be used to process straight cylinders, oblique cylinders, arcs and various threads, grooves, worms and other complex workpieces. Multi-head vertical CNC lathe is a special CNC lathe, where "multi-head" refers to the shape of the thread. When processing threads on a CNC lathe, if you need to process multiple threads, that is, the thread profile is not a continuous single spiral line, but is composed of multiple parallel spiral lines. This thread shape is called a multi-start thread. When processing multiple threads, the lathe ensures that each spiral line can be formed correctly through precise control and adjustment, so as to obtain the required multi-start thread product. Therefore, the multi-head vertical CNC lathe is mainly used to process threads with multiple spiral lines.

[0003] At present, in the relevant CNC lathe technology, a large amount of metal waste mixed with cutting fluid will be generated when processing metal parts. The metal waste can be recycled. The waste trough of the CNC lathe in the relevant technology does not have the separation and drying function, which makes it inconvenient for the staff to recycle the metal waste. In addition, the waste chips generated during cutting are piled up in the waste trough of the CNC lathe and are relatively fluffy, resulting in a large actual space occupied by the waste chips, which increases the staff's waste chip processing cycle and increases the staff's workload and labor intensity.

[0020] S1: After the metal workpiece is positioned by the hydraulic chuck, the cutting processing unit cuts the metal workpiece. The waste chips and cutting fluid generated during the processing fall into the waste tank. The filter plate at the bottom of the waste tank intercepts and filters the waste chips, and the cutting fluid passes through the filter holes of the filter plate and enters the waste tank;

[0021] S2: After the metal workpiece is cut, the staff controls the hydraulic cylinder to operate, and the plunger rod of the hydraulic cylinder applies thrust to the push plate, and the push plate drives the L-shaped plate to move through the elastic telescopic member, so that the L-shaped plate blocks the top opening of the waste tank;

[0022] S3: During the movement of the L-shaped plate, the fixed rod on the lower side of the L-shaped plate cooperates with the track groove on the driven wheel, so that the fixed rod pushes the driven wheel on the transmission rod to rotate, and the driven wheel drives the reciprocating screw to rotate through the synchronous wheel and the synchronous belt. When the reciprocating screw rotates, the engagement between the moving gears drives the rotating rod to rotate, and the knocking ball on the movable block outside the rotating rod intermittently pushes the lower plate body, so that the lower plate body collides with the upper plate body, causing the waste chips accumulated on the upper plate body to shake, thereby accelerating the downward flow of the residual cutting fluid on the waste chips;

[0023] S4: With the continuous pushing of the plunger rod, after the movement of the end of the L-shaped plate is limited, the pushing plate pushes against the waste chips between the inner wall of the waste tank and the L-shaped plate and the filter plate, the elastic telescopic member is stretched, and the air in the inner tube enters the outer tube, is heated by the electric heating member, and is discharged to the waste tank through the exhaust hole, so that the surface of the waste chips is quickly dried;

[0025] S6: After the waste chips are extruded and formed, the hydraulic cylinder controls the plunger rod to reset and move back, and the push plate drives the waste chip block to move through the plug rod, so that the waste chip block moves to the side of the waste trough. The waste chip block will not block the waste chips and cutting fluid generated during the subsequent cutting of metal parts.

[0026] Compared with the prior art, the present invention provides a multi-head vertical CNC lathe and a method for using the same, which have the following beneficial effects:

[0027] 1. The multi-head vertical CNC lathe and the method for using the same can respectively recycle the waste chips and cutting fluid generated when the lathe processes metal parts by providing a waste tank and a waste liquid tank, and can squeeze the waste chips in the waste tank by providing a pushing component, thereby reducing the space occupied by the waste chips, thereby reducing the recycling cycle and difficulty of the waste chips for the staff and improving work efficiency.

[0028] 2. The multi-head vertical CNC lathe and the method for using the same, utilize the transmission assembly to drive the impact assembly to move when the pushing assembly is working, so that the impact assembly impacts the filter plate, the waste chips on the filter plate shake, and the separation of the residual cutting fluid on the waste chips is accelerated, and the impact assembly collides with the upper plate body through the lower plate body, so that the push rod on the lower plate body is inserted into the filter hole of the upper plate body, to avoid that part of the waste chips are squeezed into the filter hole of the upper plate body when the pushing assembly pushes the waste chips, and the waste chip block is integrated with the filter plate, which affects the subsequent water flow rate of the filter plate and the picking and placing of the waste chip block after squeezing, thereby ensuring the smooth recovery of waste chips and cutting fluid.

[0029] 3. The multi-head vertical CNC lathe and the method for using the same, when the pushing assembly is working, the pushing plate squeezes the dry waste chips, the elastic telescopic rod is squeezed, the insertion rod passes through the pushing plate and is inserted into the extruded waste chip block. After the waste chips are extruded, the hydraulic cylinder controls the plunger rod to reset and move back, and the pushing plate drives the waste chip block to move through the insertion rod, so that the waste chip block moves to the side of the waste trough.

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0044] Example 1: Reference Figure 1 , Figure 2 and Figure 5A multi-head vertical CNC lathe includes a lathe body 1, on which a PLC controller 101, a hydraulic chuck 102 and a cutting processing part 103 are arranged, and further includes:

[0045] A waste tank 2, which is disposed in the lathe body 1 and is placed on the lower side of the hydraulic chuck 102;

[0046] A waste liquid tank 3, which is placed at the lower side of the waste material tank 2 and has a filter plate 4 disposed between the waste liquid tank 3 and the waste material tank 2, and an impact component that is movably opposed to the filter plate 4 is disposed in the waste liquid tank 3; and

[0047] A pushing assembly is arranged in the lathe body 1 and is used to push the waste in the waste tank 2. A working tank 5 for the movement of the pushing assembly is provided in the lathe body 1;

[0048] The lathe body 1 is connected with a transmission assembly connected with the impact assembly and the push assembly.

[0049] Specifically, after the metal workpiece is positioned by the hydraulic chuck 102, the cutting processing part 103 cuts the metal workpiece, and the waste chips and cutting fluid generated during the processing fall into the waste trough 2. The filter plate 4 at the bottom of the waste trough 2 intercepts and filters the waste chips, and the cutting fluid passes through the filter holes of the filter plate 4 and enters the waste liquid trough 3. By setting the waste trough 2 and the waste liquid trough 3, the waste chips and cutting fluid generated when the lathe processes the metal workpiece can be recycled respectively, and by setting the pushing component, the waste chips in the waste trough 2 are squeezed, which can reduce the space occupied by the waste chips, thereby reducing the recycling cycle and recycling difficulty of the waste chips by the staff, and improving the work efficiency. When the pushing component is working, the transmission component is used to drive the impact component to move, so that the impact component impacts the filter plate 4, and the waste chips on the filter plate 4 shake, which accelerates the separation of the residual cutting fluid on the waste chips, thereby ensuring the smooth recovery of the waste chips and cutting fluid; it should be noted that a cabinet door is provided on the side of the lathe body 1 to facilitate the removal of the waste chip block in the waste trough 2, and the waste liquid trough 3 is connected to a drainage channel.

[0050] Example 2: Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 , a multi-head vertical CNC lathe, based on Example 1, further, the pushing assembly includes an L-shaped plate 6 slidably connected to the working groove 5 and the waste groove 2, an elastic telescopic part 7 is arranged in the L-shaped plate 6, and a pushing plate 8 is arranged at one end of the elastic telescopic part 7 away from the L-shaped plate 6, and a hydraulic cylinder 9 is arranged between the inner wall of the working groove 5 and the pushing plate 8.

[0051] Specifically, after the cutting of the metal workpiece is completed, the staff controls the operation of the hydraulic cylinder 9, and the plunger rod of the hydraulic cylinder 9 applies a thrust to the push plate 8. The push plate 8 drives the L-shaped plate 6 to move through the elastic telescopic member 7, so that the L-shaped plate 6 blocks the top opening of the waste trough 2. With the continuous pushing of the plunger rod, after the movement of the end of the L-shaped plate 6 is restricted, the push plate 8 pushes the waste chips between the inner wall of the waste trough 2 and the L-shaped plate 6 and the filter plate 4. The elastic telescopic member 7 is stretched, and the push plate 8 continues to move horizontally between the L-shaped plate 6 and the filter plate 4. The push plate 8 squeezes the waste chips, which can reduce the space occupied by the waste chips, thereby reducing the recycling cycle and recycling difficulty of the waste chips for the staff, and improving work efficiency.

[0052] Example 3: Reference Figure 2 , Figure 5 and Figure 6 , a multi-head vertical CNC lathe, based on Example 2, further, the plunger rod of the hydraulic cylinder 9 is connected to an elastic telescopic rod 10, the end of the elastic telescopic rod 10 away from the hydraulic cylinder 9 is fixedly connected to the push plate 8, and a connecting plate 1001 is fixedly provided on the outer side of the elastic telescopic rod 10, and an insertion rod 1002 slidingly connected to the push plate 8 is fixedly provided on the connecting plate 1001.

[0053] Specifically, the staff controls the operation of the hydraulic cylinder 9, and the plunger rod of the hydraulic cylinder 9 applies a thrust to the push plate 8. The push plate 8 drives the L-shaped plate 6 to move through the elastic telescopic member 7, so that the L-shaped plate 6 blocks the top opening of the waste trough 2. With the continuous pushing of the plunger rod, after the movement of the end of the L-shaped plate 6 is restricted, the push plate 8 pushes the waste chips between the inner wall of the waste trough 2, the L-shaped plate 6 and the filter plate 4, and the elastic telescopic rod 10 is squeezed. The insertion rod 1002 passes through the push plate 8 and is inserted into the extruded waste chip block. After the waste chips are extruded, the hydraulic cylinder 9 controls the plunger rod to reset and move back. The push plate 8 drives the waste chip block to move through the insertion rod 1002, so that the waste chip block moves to the side of the waste trough 2. The waste chip block will not block the waste chips and cutting fluid generated during the subsequent cutting of metal parts, thereby ensuring the smooth downstream of the cutting fluid and improving the recovery effect and efficiency of the cutting fluid.

[0056] Specifically, the staff controls the operation of the hydraulic cylinder 9, and the plunger rod of the hydraulic cylinder 9 applies a thrust to the push plate 8. The push plate 8 drives the L-shaped plate 6 to move through the elastic telescopic member 7, so that the L-shaped plate 6 blocks the top opening of the waste trough 2. With the continuous pushing of the plunger rod, after the movement of the end of the L-shaped plate 6 is restricted, the push plate 8 pushes the waste chips between the inner wall of the waste trough 2, the L-shaped plate 6 and the filter plate 4, and the elastic telescopic member 7 is stretched. The air in the inner tube 7012 enters the outer tube 7011, is heated by the electric heating member 7014, and is discharged to the waste trough 2 through the exhaust hole 11, so that the surface of the waste chips is quickly dried, avoiding the surface being wet and the presence of more cutting fluid when the waste chips are recovered, thereby improving the waste chip extrusion molding and recycling effect.

[0057] Example 5: Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig.10 and Fig.11 , a multi-head vertical CNC lathe, based on Example 4, further, the impact component includes a rotating rod 12 rotatably connected to the waste liquid tank 3, the rotating rod 12 is provided with a movable block 121, the movable block 121 is rotatably connected to a knocking ball 122 that is movably against the filter plate 4, the rotating rod 12 is provided with a guide groove 123, and the knocking ball 122 is provided with a guide strip 1221 that matches the guide groove 123.

[0059] Furthermore, the transmission assembly includes a bracket 15 fixedly mounted in the working groove 5, a transmission rod 151 is rotatably connected to the bracket 15, a synchronous wheel 16 is provided on the transmission rod 151 and the reciprocating screw rod 13, a synchronous belt is provided between the two synchronous wheels 16, a driven wheel 152 is fixedly mounted on the transmission rod 151, a plurality of track grooves 1521 are formed on the driven wheel 152, and a plurality of fixing rods 601 matching the track grooves 1521 are fixedly mounted on the L-shaped plate 6.

[0060] Specifically, the staff controls the operation of the hydraulic cylinder 9, and the plunger rod of the hydraulic cylinder 9 applies a thrust to the push plate 8. The push plate 8 drives the L-shaped plate 6 to move through the elastic telescopic member 7, so that the L-shaped plate 6 blocks the top opening of the waste tank 2. During the movement of the L-shaped plate 6, the fixed rod 601 on the lower side of the L-shaped plate 6 cooperates with the track groove 1521 on the driven wheel 152, so that the fixed rod 601 pushes the driven wheel 152 on the transmission rod 151 to rotate, and the driven wheel 152 drives the reciprocating screw rod 13 to rotate through the synchronous wheel 16 and the synchronous belt. When the reciprocating screw rod 13 rotates, it is driven to rotate through the meshing between the moving gears 14. The rod 12 rotates, and the knocking ball 122 on the movable block 121 outside the rotating rod 12 intermittently impacts the filter plate 4, causing the waste chips accumulated on the filter plate 4 to shake, thereby accelerating the rapid downflow of the residual cutting fluid on the waste chips, and the sleeve 131 reciprocates along the axial direction of the reciprocating screw rod 13 when the reciprocating screw rod 13 rotates, so that the sleeve 131 drives the knocking ball 122 to move back and forth through the movable block 121, so that the impact points of the filter plate 4 are distributed along a straight line, and then the cutting fluid remaining on the surface of the waste chips at various places on the filter plate 4 can be subjected to the same vibration amplitude, thereby improving the separation effect of the cutting fluid and the waste chips, and ensuring the smooth recovery of the waste chips and the cutting fluid.

[0061] Example 6: Reference Figure 2 , Figure 5 and Fig. 9 , a multi-head vertical CNC lathe, on the basis of Example 5, further, the filter plate 4 includes an upper plate body 401 fixedly connected to the lower side of the waste tank 2, a second elastic element 402 fixedly arranged on the lower side of the upper plate body 401, and a lower plate body 403 fixedly connected to one end of the second elastic element 402 away from the upper plate body 401, the lower plate body 403 is slidably connected in the waste liquid tank 3 and is movably abutted against the knocking ball 122, the filter holes of the lower plate body 403 and the upper plate body 401 are staggered, and the lower plate body 403 is fixedly provided with a top rod 4031 plugged into the filter hole of the upper plate body 401.

[0062] Specifically, during the movement of the L-shaped plate 6, the fixed rod 601 on the lower side of the L-shaped plate 6 cooperates with the track groove 1521 on the driven wheel 152, so that the fixed rod 601 pushes the driven wheel 152 on the transmission rod 151 to rotate, and the driven wheel 152 drives the reciprocating screw rod 13 to rotate through the synchronous wheel 16 and the synchronous belt. When the reciprocating screw rod 13 rotates, the engagement between the moving gears 14 drives the rotating rod 12 to rotate, and the knocking ball 122 on the outer movable block 121 of the rotating rod 12 intermittently pushes the lower plate body 403, causing the lower plate body 403 to collide with the upper plate body 4 01, so that the waste chips accumulated on the upper plate body 401 are shaken, and the cutting fluid remaining on the waste chips is accelerated to flow down quickly, and the impact component collides with the upper plate body 401 through the lower plate body 403, so that the push rod 4031 on the lower plate body 403 is inserted into the filter hole of the upper plate body 401, so as to avoid that when the pushing component pushes the waste chips, part of the waste chips are squeezed into the filter hole of the upper plate body 401, resulting in the waste chip block and the filter plate 4 being combined into one, affecting the subsequent water flow rate of the filter plate 4 and the removal and placement of the waste chip block after extrusion molding, thereby ensuring the smooth recovery of waste chips and cutting fluid.

[0066] S3: During the movement of the L-shaped plate 6, the fixed rod 601 on the lower side of the L-shaped plate 6 cooperates with the track groove 1521 on the driven wheel 152, so that the fixed rod 601 pushes the driven wheel 152 on the transmission rod 151 to rotate, and the driven wheel 152 drives the reciprocating screw 13 to rotate through the synchronous wheel 16 and the synchronous belt. When the reciprocating screw 13 rotates, the engagement between the moving gears 14 drives the rotating rod 12 to rotate, and the knocking ball 122 on the movable block 121 outside the rotating rod 12 intermittently pushes the lower plate body 403, so that the lower plate body 403 collides with the upper plate body 401, so that the waste chips accumulated on the upper plate body 401 are shaken, and the residual cutting fluid on the waste chips is accelerated to flow down;

10. A method for using the multi-head vertical CNC lathe according to claim 9, characterized in that: The following steps are involved: S1: After the metal workpiece is positioned by the hydraulic chuck (102), the cutting processing unit (103) performs cutting processing on the metal workpiece, and the waste chips and cutting fluid generated during the processing fall into the waste material tank (2). The filter plate (4) at the bottom of the waste material tank (2) intercepts and filters the waste chips, and the cutting fluid passes through the filter holes of the filter plate (4) and enters the waste liquid tank (3); S2: After the cutting process of the metal workpiece is completed, the staff controls the hydraulic cylinder (9) to operate, and the plunger rod of the hydraulic cylinder (9) applies a thrust to the push plate (8), and the push plate (8) drives the L-shaped plate (6) to move through the elastic telescopic member (7), so that the L-shaped plate (6) blocks the top opening of the waste trough (2); S3: During the movement of the L-shaped plate (6), the fixed rod (601) on the lower side of the L-shaped plate (6) cooperates with the track groove (1521) on the driven wheel (152), so that the fixed rod (601) pushes the driven wheel (152) on the transmission rod (151) to rotate, and the driven wheel (152) drives the reciprocating screw (13) to rotate through the synchronous wheel (16) and the synchronous belt. When the reciprocating screw (13) rotates, the engagement between the moving gears (14) drives the rotating rod (12) to rotate, and the knocking ball (122) on the outer movable block (121) of the rotating rod (12) intermittently pushes the lower plate body (403), so that the lower plate body (403) collides with the upper plate body (401), so that the waste chips accumulated on the upper plate body (401) are shaken, thereby accelerating the downward flow of the residual cutting fluid on the waste chips; S4: As the plunger rod continues to push, after the movement of the end of the L-shaped plate (6) is restricted, the push plate (8) pushes against the waste chips between the inner wall of the waste trough (2) and the L-shaped plate (6) and the filter plate (4), the elastic telescopic member (7) is stretched, and the air in the inner tube (7012) enters the outer tube (7011), is heated by the electric heating member (7014), and is discharged to the waste trough (2) through the exhaust hole (11), so that the surface of the waste chips is quickly dried; S5: Then the push plate (8) continues to move horizontally between the L-shaped plate (6) and the filter plate (4), the push plate (8) squeezes the dry waste, the elastic telescopic rod (10) is squeezed, and the insertion rod (1002) passes through the push plate (8) and is inserted into the extruded waste block; S6: After the waste chips are extruded and formed, the hydraulic cylinder (9) controls the plunger rod to reset and move back, and the push plate (8) drives the waste chip block to move through the insertion rod (1002), so that the waste chip block moves to the side of the waste trough (2), and the waste chip block will not block the waste chips and cutting fluid generated during the subsequent cutting of metal parts.
