Single-column numerical control vertical lathe

Abstract

The invention discloses a single-column numerical control vertical lathe, and relates to the technical field of numerical control lathes. Due to the fact that a clamp cannot be adjusted according to the material condition in the turning machining process, when the turning resistance of materials is large, the materials cannot be driven to rotate at a high speed, and turning machining of the materials is affected, the single-column numerical control vertical lathe is matched with a material clamping block through the arc groove depth change of an arc groove block, and when the turning resistance is large in the turning process, the material clamping block can be driven to rotate at a high speed. When the material and the turntable rotate relatively, the friction force between the turning material and the material clamping block is utilized, the material clamping block compresses the cushion block to deform and slide in the arc groove, and the characteristic that the depth of the arc groove is gradually reduced from the center position to the two sides is matched, so that the inner clamping block gets close to the center position again, the clamping force is increased, and the material is prevented from being damaged due to large turning resistance; and therefore, the turning of the material is influenced by the fact that the material cannot be driven to rotate at a high speed.

Description

Technical Field

[0001] The present invention relates to the technical field of numerically controlled lathes, and specifically relates to a single-column numerically controlled vertical lathe. Background Art

[0002] A single-column numerically controlled vertical lathe is a numerically controlled machine tool used for metal cutting. With a column as the main support component, the column is vertically installed on the base to provide support and guidance for other components of the machine tool. The programmed machining program is input into the numerical control system, which processes and calculates the program, and then sends command signals to the servo drive devices of each coordinate axis of the machine tool to drive the moving components such as the workbench and tool holder of the machine tool to move according to the predetermined trajectory and parameters, so as to achieve automated cutting processing of the workpiece. During the processing, the tool is fixed on the tool holder, the workbench drives the workpiece to rotate, and relative movement occurs between the tool and the workpiece to complete processing operations such as the inner and outer cylindrical surfaces, conical surfaces, end faces, grooving, and chamfering of the workpiece;

[0003] When the lathe fixes the turning material, a fixture is usually used to clamp the material. However, the fixture cannot be adjusted according to the situation of the material during the turning process, resulting in the material not being driven to rotate at high speed when the turning resistance is large, affecting the turning processing of the material. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0005] A single-column numerically controlled vertical lathe, comprising:

[0006] A frame body, at the bottom of which a first motor is fixedly installed, and the output end of the first motor penetrates the frame body and extends to its top;

[0007] An adjusting mechanism for adjusting the tool position of the lathe. The adjusting mechanism is installed on the outside of the frame body, and a tool mechanism is fixedly installed on the outside of the adjusting mechanism;

[0008] The output end of the first motor is fixedly connected with a turntable. The turntable is rotatably installed on the top of the frame body. A plurality of strip grooves are evenly formed in the top of the turntable. Cylinders are fixedly installed at the strip grooves of the turntable. Slide blocks are slidably installed at the strip grooves of the turntable. The slide blocks are located inside the cylinders, and the outer sides of the slide blocks are fixedly connected with the output ends of the cylinders. The top of the slide block is fixedly connected with an arc groove block. An arc groove is formed in the outer side of the arc groove block, and the depth of the arc groove gradually decreases from the central position to both sides. By the change of the depth of the arc groove of the arc groove block cooperating with the material clamping block, during turning, when the turning resistance is large and relative rotation occurs between the material and the turntable, by using the friction force between the turning material and the material clamping block, the material clamping block compresses the cushion block to deform and slide in the arc groove. With the characteristic that the depth of the arc groove gradually decreases from the central position to both sides, the inner clamping block moves closer to the central position again, increasing the clamping force and restricting the relative rotation between the material and the turntable, preventing the material from being unable to be driven to rotate at high speed due to the large turning resistance, which affects the turning processing of the material. A material clamping block is slidably installed at the arc groove of the arc groove block. A cushion block is clamped at the chute of the arc groove block. Through the elastic deformation characteristic of the cushion block, during the process of clamping the material, the two sides of the material clamping block are restricted, so that the material clamping block is located at the central position of the arc groove of the arc groove block when clamping the material, and the material clamping block is at the deepest part of the arc groove before turning, ensuring the cooperation between the arc groove block and the material clamping block during turning, avoiding the material clamping block being at one end of the arc groove during clamping, resulting in inability to adjust during turning. At the same time, the material clamping blocks at the central position synchronously can ensure the positioning of the material during clamping, so that the material is at the rotation center position, avoiding material deviation affecting the turning processing. The cushion block is made of an elastic material and is symmetrically installed along the axis center position of the arc groove block. The opposite surfaces of the cushion block are in contact with the two sides of the material clamping block. Side clamping blocks are fixedly installed at the tops of both sides of the slide block. The opposite surfaces of the side clamping blocks are closely attached to the two sides of the arc groove block. The opposite surfaces of the material clamping block are arc surfaces.

[0009] Preferably, the adjusting mechanism includes a second motor fixedly installed at the top of the frame body, and the output end of the second motor penetrates the frame body and extends to its bottom. The output end of the second motor is fixedly connected to a first screw rod. A first screw block is threadedly connected to the outer side of the first screw rod. A connecting cross plate is fixedly connected to the outer side of the first screw block. Connecting plates are slidably installed at both ends of the connecting cross plate. The top of the side of the connecting plate close to the frame body is fixedly connected to the outer side of the frame body, and through grooves are symmetrically formed on the outer side of the connecting plate. The connecting plate is slidably adapted to both ends of the connecting cross plate through the through grooves. Slide groove frames are fixedly connected to both ends of the connecting cross plate. A third motor is fixedly connected to the outer side of the slide groove frame, and a second screw rod is rotatably connected to the inner wall of the slide groove frame. One end of the second screw rod is fixedly connected to the output end of the third motor. A second screw block is threadedly connected to the outer side of the second screw rod. The outer side of the second screw block is slidably adapted to the inner wall of the slide groove frame. One end of the second screw block is fixedly connected to a fixing plate. The outer side of the fixing plate is fixedly connected to the tool mechanism. Card slots are formed on both the upper and lower sides of the inner wall of the slide groove frame.

[0010] Preferably, a bottom strip is fixedly connected to the bottom of the second screw block, and a top strip is fixedly connected to the top of the second screw block. The outer side of the top strip is slidably adapted to the card slot above the inner wall of the slide groove frame, and grooves are symmetrically formed at the top of the top strip. Rotating balls are rotatably installed at the groove positions of the top strip. Through the cooperation of the top strip and the bottom strip, when sliding, it is slidably adapted to the card slot of the slide groove frame. At the same time, when the turning resistance is relatively large and the second screw block shows a tendency to tilt, the tilt of the second screw block is restricted, avoiding the second screw rod from being bent under force, resulting in the screw rod breaking or bending and deforming, and being unable to drive the tool to move precisely, affecting the quality of turning processing. The outer side of the bottom strip is slidably adapted to the card slot below the inner wall of the slide groove frame, and both ends of the bottom strip are beveled surfaces. Sliding grooves are symmetrically formed at the bottom of the bottom strip, and scraping groove strips are slidably installed at the sliding groove positions of the bottom strip. The non-opposite surfaces of the scraping groove strips are beveled surfaces and are adapted to the beveled surfaces at both ends of the bottom strip. Through the beveled surfaces of the scraping groove strips, when sliding in the card slot, the turning debris at the lower card slot is cleaned, and at the same time, by using the beveled surfaces at both ends of the bottom strip, the debris is exported from the card slot during sliding, avoiding the accumulation of turning debris at the card slot and affecting the movement of the tool. At the same time, the elastic cushion rings utilize their own elastic deformation to cooperate with the scraping groove strips to perform buffering adjustment when the scraping of the scraping groove strips is blocked. Elastic cushion rings are fixedly installed on the opposite surfaces of the scraping groove strips.

[0011] Preferably, the tool mechanism includes a fixed seat. One end of the fixed seat is fixedly connected to the outer side of the fixed plate. A fourth motor is fixedly connected to the top of the fixed seat. The output end of the fourth motor penetrates through the fixed seat and extends to its bottom. The output end of the fourth motor is fixedly connected to a transmission shaft. A cutter head is fixedly connected to the bottom end of the transmission shaft. Knife grooves are evenly formed on the outer side of the cutter head. Turning tool heads are installed at the knife groove positions of the cutter head. The inner wall of the turning tool head is threadedly connected with a first bolt. The turning tool head is fixedly connected to the knife groove of the cutter head through the first bolt. Side clamping plates are slidably installed at the knife groove positions of the cutter head. The side clamping plates are symmetrically installed along the central axis position of the knife groove. The opposite surfaces of the side clamping plates are inclined surfaces that incline outward from top to bottom. Through the inclined surfaces of the side clamping plates, when the turning tool head is machining a material, the turning tool head is restricted to prevent the turning tool head from loosening due to large turning resistance, which affects the turning accuracy. At the same time, the inclined surface from top to bottom restricts the turning tool head from tilting when the turning tool head moves from top to bottom for turning, avoiding the fracture of the bolt fixing the turning tool head and causing the tool to fly. The inclined surfaces of the side clamping plates are in contact with both sides of the turning tool head. A second bolt is rotatably connected to the inner wall of the side clamping plate. The side clamping plate is fixedly connected to the inner wall of the cutter head through the second bolt.

[0012] The present invention provides a single-column CNC vertical lathe. It has the following beneficial effects:

[0013] First, in this single-column CNC vertical lathe, through the change in the arc groove depth of the arc groove block and the cooperation with the clamping block, during turning, when the turning resistance is large and relative rotation occurs between the material and the turntable, the friction between the turning material and the clamping block is utilized to cause the clamping block to compress the cushion block and deform, slide in the arc groove, and cooperate with the characteristic that the arc groove depth gradually decreases from the central position to both sides, so that the inner clamping block moves closer to the central position again, increasing the clamping force and restricting the relative rotation between the material and the turntable, preventing the material from being unable to be driven to rotate at high speed due to large turning resistance, which affects the turning processing of the material.

[0014] Second, in this single-column CNC vertical lathe, through the elastic deformation characteristic of the cushion block, during the process of clamping the material, the two sides of the clamping block are restricted, so that the clamping block is located at the central position of the arc groove of the arc groove block when clamping the material, and the clamping block is at the deepest part of the arc groove before turning, ensuring the cooperation between the arc groove block and the clamping block during turning, avoiding the clamping block being at one end of the arc groove during clamping, resulting in inability to adjust during turning. At the same time, the clamping block at the central position synchronously can ensure the positioning of the material during clamping, making the material at the rotation center position, avoiding material deviation and affecting turning processing.

[0015] III. In this single-column CNC vertical lathe, through the cooperation of the top strip and the bottom strip, when sliding, it is slidably adapted to the card slot of the chute frame. At the same time, when the turning resistance is relatively large and the second screw block shows a tendency to tilt, the tilt of the second screw block is restricted, avoiding the force-induced bending of the second screw rod, resulting in the fracture or bending deformation of the screw rod, and being unable to drive the tool to move precisely, thus affecting the quality of turning processing.

[0016] IV. In this single-column CNC vertical lathe, through the inclined surface of the groove cleaning strip, when sliding in the card slot, the turning debris at the lower card slot is cleaned. At the same time, by using the inclined surfaces at both ends of the bottom strip, the debris is exported from the card slot when sliding, avoiding the accumulation of turning debris at the card slot and affecting the movement of the tool. At the same time, the elastic cushion ring uses its own elastic deformation to cooperate with the groove cleaning strip to buffer and adjust when the groove cleaning strip is blocked during debris cleaning.

[0017] V. In this single-column CNC vertical lathe, through the inclined surface of the side clamping plate, when the cutting tool head is turning the processing material, the cutting tool head is restricted, avoiding the loosening of the cutting tool head due to the relatively large turning resistance and affecting the turning accuracy. At the same time, the inclined surface from top to bottom restricts the lifting of the cutting tool head when the cutting tool head moves from top to bottom for turning, avoiding the fracture of the bolt fixing the cutting tool head and causing the tool to fly.

Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0032] The first embodiment, as Figures 1 to 5 shown, the present invention provides a technical solution:

[0033] A single-column CNC vertical lathe, comprising:

[0034] A frame body 1, the bottom of the frame body 1 is fixedly installed with a first motor 5, and the output end of the first motor 5 penetrates through the frame body 1 and extends to its top;

[0035] An adjusting mechanism 4, which is used to adjust the tool position of the lathe. The adjusting mechanism 4 is installed on the outside of the frame body 1, and a tool mechanism 3 is fixedly installed on the outside of the adjusting mechanism 4;

[0036] The output end of the first motor 5 is fixedly connected to a turntable 2. The turntable 2 is rotatably installed on the top of the frame body 1, and strip grooves are evenly formed in the top of the turntable 2. Cylinders 6 are fixedly installed at the strip grooves of the turntable 2. Slide blocks 7 are slidably installed at the strip grooves of the turntable 2. The slide blocks 7 are located inside the cylinders 6, and the outer sides of the slide blocks 7 are fixedly connected to the output ends of the cylinders 6. After the material is placed on the top of the turntable 2, the cylinders 6 drive the slide blocks 7 to slide in the strip grooves of the turntable 2, so that the slide blocks 7 move closer to the central position. During the approaching process, the slide blocks 7 drive the clamping blocks 11 to approach the material through the arc groove blocks 8 to clamp and fix the material. At the same time, during the clamping, the cushion blocks 10 in the arc grooves of the arc groove blocks 8 limit the positions of the clamping blocks 11, so that the clamping blocks 11 are at the deepest positions at the center of the arc grooves. The top of the slide block 7 is fixedly connected to an arc groove block 8. An arc groove is formed on the outer side of the arc groove block 8, and the depth of the arc groove gradually decreases from the central position to both sides. A clamping block 11 is slidably installed at the arc groove of the arc groove block 8. A cushion block 10 is clamped at the chute of the arc groove block 8. The cushion block 10 is made of an elastic material and is symmetrically installed along the axis center position of the arc groove block 8, and the opposite surfaces of the cushion block 10 are in contact with both sides of the clamping block 11. During processing, the first motor 5 drives the turntable 2 to rotate, thereby driving the material to rotate. When turning the material, when the tool turns the material, friction occurs between the tool and the material, restricting the rotation of the material. At this time, through the frictional force when the clamping block 11 clamps the material, when relative rotation occurs between the material and the turntable 2, the clamping block 11 is synchronously driven to rotate, compressing the cushion block 10, so that the clamping block 11 slides in the arc groove of the arc groove block 8. By using the change in the depth of the arc groove of the arc groove block 8, the clamping blocks 11 approach each other again during rotation, increasing the clamping force on the material. Side clamping blocks 9 are fixedly installed at the tops of both sides of the slide block 7. The opposite surfaces of the side clamping blocks 9 are closely attached to both sides of the arc groove block 8. The opposite surfaces of the clamping blocks 11 are arc surfaces.

[0037] Second embodiment, on the basis of the first embodiment, please refer to Figures 6 to 10As shown in the figure, the adjusting mechanism 4 includes a second motor 401. The second motor 401 is fixedly installed on the top of the frame body 1, and the output end of the second motor 401 penetrates through the frame body 1 and extends to its bottom. The output end of the second motor 401 is fixedly connected with a first screw rod 402. A first nut 404 is threadedly connected to the outside of the first screw rod 402. A connecting cross plate 405 is fixedly connected to the outside of the first nut 404. Connecting plates 403 are slidably installed at both ends of the connecting cross plate 405. The top of the side of the connecting plate 403 close to the frame body 1 is fixedly connected to the outside of the frame body 1, and through grooves are symmetrically formed on the outside of the connecting plate 403. Through the input program, the second motor 401 cooperates with the third motor 407. The second motor 401 drives the first screw rod 402 to rotate. By utilizing the threaded connection between the first screw rod 402 and the first nut 404, the connecting cross plate 405 is driven to move up and down, so that the connecting cross plate 405 drives the chute frame 406 to move up and down. The connecting plate 403 is slidably adapted to both ends of the connecting cross plate 405 through the through grooves. Chute frames 406 are fixedly connected to both ends of the connecting cross plate 405. A third motor 407 is fixedly connected to the outside of the chute frame 406, and a second screw rod 409 is rotatably connected to the inner wall of the chute frame 406. One end of the second screw rod 409 is fixedly connected to the output end of the third motor 407. A second nut 408 is threadedly connected to the outside of the second screw rod 409. The outside of the second nut 408 is slidably adapted to the inner wall of the chute frame 406. One end of the second nut 408 is fixedly connected with a fixing plate 410. The third motor 407 drives the second screw rod 409 to rotate. By utilizing the threaded connection between the second screw rod 409 and the second nut 408, the second nut 408 moves horizontally on the inner wall of the chute frame 406. The second nut 408 drives the tool mechanism 3 through the fixing plate 410, so that the tool mechanism 3 realizes up and down movement and horizontal movement under the drive of the adjusting mechanism 4. The outside of the fixing plate 410 is fixedly connected to the tool mechanism 3. Card slots are formed on both the upper and lower sides of the inner wall of the chute frame 406.

[0038] A bottom bar 412 is fixedly connected to the bottom of the second screw block 408, and a top bar 413 is fixedly connected to the top of the second screw block 408. The outer side of the top bar 413 is slidably fitted with a clamping groove above the inner wall of the chute frame 406. Grooves are symmetrically formed at the top of the top bar 413. During the movement of the second screw block 408, the top bar 413 and the bottom bar 412 slide in the clamping groove of the chute frame 406. Meanwhile, during the sliding process, the top bar 413 and the bottom bar 412 contact the clamping groove of the chute frame 406 to support the resistance during turning the material. When the turning resistance is large, the inclination of the second screw block 408 is restricted to avoid all the turning resistance being borne by the second screw block 408 and the second screw 409. Rotating balls 411 are rotatably installed at the groove positions of the top bar 413. The outer side of the bottom bar 412 is slidably fitted with a clamping groove below the inner wall of the chute frame 406, and both ends of the bottom bar 412 are beveled. Sliding grooves are symmetrically formed at the bottom of the bottom bar 412, and scraping groove bars 415 are slidably installed at the sliding groove positions of the bottom bar 412. During the sliding process, the top bar 413 cooperates with the rotating balls 411 to reduce the sliding resistance. The beveled surfaces at both ends of the bottom bar 412 cooperate with the scraping groove bars 415 to clean the lower clamping groove, preventing turning chips from splashing and falling into the clamping groove to cause blockage. The non-opposite surfaces of the scraping groove bars 415 are beveled and adapted to the beveled surfaces at both ends of the bottom bar 412. Elastic cushion rings 414 are fixedly installed on the opposite surfaces of the scraping groove bars 415.

[0039] The third embodiment, on the basis of the first and second embodiments, please refer to Figures 11 to 12 As shown, the tool mechanism 3 includes a fixed seat 31. One end of the fixed seat 31 is fixedly connected to the outer side of the fixed plate 410, and a fourth motor 32 is fixedly connected to the top of the fixed seat 31. The output end of the fourth motor 32 penetrates through the fixed seat 31 and extends to its bottom. Through the connection between the fixed seat 31 and the fixed plate 410, the fourth motor 32 and the transmission shaft 33 are driven to move, so that the tool disc 34 drives the tool to approach the material for turning. The output end of the fourth motor 32 is fixedly connected to a transmission shaft 33, the bottom end of the transmission shaft 33 is fixedly connected to a tool disc 34, evenly distributed tool grooves are formed on the outer side of the tool disc 34, and turning tool heads 35 are installed at the tool groove positions of the tool disc 34. The inner wall of the turning tool head 35 is threadedly connected with a first bolt 37, and the turning tool head 35 is fixedly connected to the tool groove of the tool disc 34 through the first bolt 37.

[0040] Side clamping plates 36 are slidably installed at the tool grooves of the cutter head 34. The side clamping plates 36 are symmetrically installed along the central axis position of the tool groove, and the opposite surfaces of the side clamping plates 36 are inclined planes that slope outward from top to bottom. The inclined planes of the side clamping plates 36 are in contact with both sides of the cutting tool head 35. In the cutter head 34, the cutting tool head 35 is fixed at the tool groove of the cutter head 34 by the first bolt 37. The cutter head 34 is used to drive the cutting tool head 35 close to the material, so that the cutting tool head 35 contacts the rapidly rotating material to achieve turning processing work. At the same time, when the cutting tool head 35 is turning the material, the two side clamping plates 36 limit both sides of the cutting tool head 35 to clamp the cutting tool head 35. A second bolt 38 is rotatably connected to the inner wall of the side clamping plate 36, and the side clamping plate 36 is fixedly connected to the inner wall of the cutter head 34 through the second bolt 38.

[0041] During use, the worker places the material to be turned on the top of the turntable 2 for fixation through a handling device, and drives the material to rotate through the first motor 5. Subsequently, the worker inputs the turning program, so that the adjusting mechanism 4 cooperates with the tool mechanism 3, and the adjusting mechanism 4 drives the tool mechanism 3 to move, so that the tool mechanism 3 turns the material.

[0042] When fixing the turning material, after the material is placed on the top of the turntable 2, the cylinder 6 drives the sliding block 7 to slide in the strip groove of the turntable 2, so that the sliding block 7 moves closer to the central position. During the approaching process, the sliding block 7 drives the clamping block 11 to approach the material through the arc groove block 8 to clamp and fix the material. At the same time, during clamping, the cushion block 10 in the arc groove of the arc groove block 8 limits the position of the clamping block 11, so that the clamping block 11 is at the deepest position in the center of the arc groove. During processing, the first motor 5 drives the turntable 2 to rotate, thereby driving the material to rotate. When the tool turns the material, friction occurs between the tool and the material, restricting the rotation of the material. At this time, through the friction force when the clamping block 11 clamps the material, when relative rotation occurs between the material and the turntable 2, the clamping block 11 is synchronously driven to rotate, compressing the cushion block 10, so that the clamping block 11 slides in the arc groove of the arc groove block 8. By using the change in the arc groove depth of the arc groove block 8, the clamping blocks 11 approach each other again during rotation, increasing the clamping force on the material.

[0043] In the adjusting mechanism 4, through the input program, the second motor 401 and the third motor 407 cooperate. The second motor 401 drives the first screw rod 402 to rotate. By using the threaded connection between the first screw rod 402 and the first screw block 404, the connecting cross plate 405 is driven to move up and down, so that the connecting cross plate 405 drives the chute frame 406 to move up and down. At the same time, the third motor 407 drives the second screw rod 409 to rotate. By using the threaded connection between the second screw rod 409 and the second screw block 408, the second screw block 408 moves horizontally on the inner wall of the chute frame 406. The second screw block 408 drives the tool mechanism 3 through the fixing plate 410, so that the tool mechanism 3 realizes up and down movement and horizontal movement under the drive of the adjusting mechanism 4.

[0044] During the movement of the second screw block 408, the top bar 413 and the bottom bar 412 slide in the card slots of the chute frame 406. At the same time, during the sliding process, the top bar 413 and the bottom bar 412 contact the card slots of the chute frame 406 to support the resistance during turning the material. When the turning resistance is large, the inclination of the second screw block 408 is restricted, avoiding that all the turning resistance is borne by the second screw block 408 and the second screw rod 409. At the same time, during the sliding process, the top bar 413 cooperates with the rotating ball 411 to reduce the sliding resistance. The inclined surfaces at both ends of the bottom bar 412 cooperate with the shovel groove bar 415 to clean the lower card slots, avoiding turning debris from splashing into the card slots and causing blockage.

[0045] In the tool mechanism 3, through the connection between the fixed seat 31 and the fixing plate 410, the fourth motor 32 and the transmission shaft 33 are driven to move, so that the tool disc 34 drives the tool to approach the material for turning. At the same time, in the tool disc 34, the tool bit 35 is fixed at the tool groove of the tool disc 34 through the first bolt 37. By using the tool disc 34 to drive the tool bit 35 to approach the material, the tool bit 35 contacts the high-speed rotating material to realize the turning processing work. At the same time, when the tool bit 35 turns the material, the side clamping plates 36 on both sides limit both sides of the tool bit 35 to clamp the tool bit 35.
