Description

Technical Field

[0001] This invention relates to a lathe, specifically a pneumatic lathe. Background Technology

[0002] A lathe is a machine tool primarily used to machine rotating workpieces using a cutting tool. Drills, reamers, taps, dies, and knurling tools can also be used on a lathe for corresponding machining operations. Lathes are mainly used for machining shafts, discs, sleeves, and other workpieces with rotating surfaces, and are the most widely used type of machine tool in machinery manufacturing and repair shops. Lathes are further divided into pneumatic lathes and CNC lathes, among other types.

[0003] Traditional pneumatic lathes typically use air pressure to move the cutting tool and perform machining operations on parts. However, during operation, the machining process between the tool and the workpiece generates a large amount of metal shavings that fall onto the worktable surface. The traditional cleaning method usually involves workers manually cleaning with hand tools, which increases the workload for workers and leaves residues. Summary of the Invention

Cleaning mechanisms are provided on both the left and right sides of the machine tool body, and a U-shaped plate fixedly connected to the top of the machine tool body. The inner cavity of the U-shaped plate has two clamping plates arranged one behind the other, and several No. 1 springs are fixedly connected to the side of the two clamping plates that is away from each other. The end of each No. 1 spring away from the clamping plate is fixedly connected to one side of the inner wall of the U-shaped plate.

[0007] As a preferred embodiment of the present invention, the connecting mechanism includes a plug block, which is fixedly connected to the bottom of the cylinder. A slot is provided on the top of the tool holder, and the plug block is movably connected to the inner cavity of the slot. Circular grooves are provided on both the left and right sides of the plug block. Cylinders are fixedly connected to both the left and right sides of the tool holder. A stop block is provided in the inner cavity of each of the two cylinders, and a handle is attached to the side of each cylinder that is far apart from the other. A round rod is fixedly connected to the opposite side of each of the two handles. One end of the round rod passes through the cylinder, the stop block, and the side wall of the tool holder, and is inserted into the inner cavity of the corresponding circular groove. The round rod, cylinder, and side wall of the tool holder are movably connected, and a second spring is sleeved on the outside of the round rod. The two ends of the second spring are fixedly connected to the stop block and the inner wall of the cylinder, respectively.

[0008] As a preferred embodiment of the present invention, the cleaning mechanism includes a collection box, which is fixedly connected to the side wall of the machine tool body. A conduit is inserted into the top of the collection box, and an air pump is inserted into the top of the conduit. A suction pipe is inserted into one side of the air pump.

[0009] As a preferred embodiment of the present invention, the inner wall of the slot is provided with limit grooves on both the front and rear sides, and the insert block is fixedly connected to limit strips on both the front and rear sides, with the limit strips being movably connected to the inner cavity of the corresponding limit groove.

[0010] As a preferred embodiment of the present invention, a sleeve is fitted on the outside of the suction pipe, a rack is fixedly connected to the top of the sleeve, a gear is meshed on the top of the rack, L-shaped plates are fixedly connected to both the front and rear sides of the vertical frame, a motor is fixedly connected to the outside of the L-shaped plate, a rotating rod is fixedly connected to one side of the motor, the end of the rotating rod away from the motor passes through the L-shaped plate and is fixedly connected to the side wall of the corresponding gear, and the rotating rod is movably connected to the L-shaped plate.

[0011] As a preferred embodiment of the present invention, both of the two collection boxes are movably equipped with boxes on the opposite side.

[0012] As a preferred embodiment of the present invention, a pump base is fixedly connected to one side of the air pump, and the pump base is fixedly connected to the side wall of the machine tool body.

[0013] This invention provides a pneumatic lathe with the following advantages:

[0014] 1. Equipped with an air pump, suction pipe, guide tube, gears, and rack, the air pump and motor are driven during the machining process of the cutting tool. The air pump generates suction force, which sucks up the debris generated during the machining process through the suction pipe and then enters the collection box through the guide tube. At the same time, the motor drives the rotating rod to rotate repeatedly, which drives the gear to rotate repeatedly. The gear drives the rack to move back and forth repeatedly, which drives the bottom sleeve to move. The sleeve drives the suction pipe to swing back and forth repeatedly. By swinging back and forth, the suction range is expanded, avoiding residue and eliminating the need for manual cleaning by the staff, thus saving the staff's workload and time.

[0015] 2. By setting up a U-shaped plate, clamping plate and No. 1 spring, the part to be processed can be placed inside the U-shaped plate before processing. The two clamping plates can clamp and fix the part to be processed under the elastic force of multiple No. 1 springs, so that the part has high stability during subsequent processing and avoids processing misalignment.

[0016] 3. Equipped with a round rod, round groove, handle, stop block, and No. 2 spring, when the tool is damaged and needs to be replaced after prolonged use, the handles on both sides can be pulled, causing the handles to move the round rod. The round rod is pulled out of the round groove, which in turn moves the stop block. The stop block compresses the No. 2 spring, allowing the tool holder and the bottom tool to be removed from the insert block, thus separating the tool holder from the cylinder. Then, the operator can disassemble and replace the tool at the bottom of the tool holder, facilitating subsequent work. Attached Figure Description

[0028] The connecting mechanism includes a plug 13, which is fixedly connected to the bottom of the cylinder 8. A slot 10 is provided on the top of the tool holder 9, and the plug 13 is movably connected to the inner cavity of the slot 10. The plug 13 has circular grooves 19 on both the left and right sides. Cylinders 14 are fixedly connected to both the left and right sides of the tool holder 9. A stop block 18 is provided in the inner cavity of each of the two cylinders 14. A handle 15 is attached to the side of each cylinder 14 that is far away from each other. A round rod 16 is fixedly connected to the opposite side of each handle 15. One end of the round rod 16 passes through the cylinder 14, the stop block 18, and the side wall of the tool holder 9, and is inserted into the inner cavity of the corresponding circular groove 19. The round rod 16 is movably connected to the cylinder 14 and the side wall of the tool holder 9. A second spring 17 is sleeved on the outside of the round rod 16. The two ends of the second spring 17 are fixedly connected to the stop block 18 and the inner wall of the cylinder 14, respectively.

[0029] In this embodiment, this setting enables the disassembly of the tool holder 9 and the cylinder 8, allowing the tool 20 at the bottom of the tool holder 9 to be easily disassembled and replaced after damage, ensuring the continued operation of subsequent work.

[0030] The cleaning mechanism includes a collection box 21, which is fixedly connected to the side wall of the machine tool body 1. A conduit 25 is inserted into the top of the collection box 21, and an air pump 23 is inserted into the top of the conduit 25. A suction pipe 26 is inserted into one side of the air pump 23.

[0031] In this embodiment, this setup enables the extraction of debris generated during processing, replacing manual cleaning by workers and saving them labor and time.

[0032] Among them, the slot 10 has limit grooves 11 on both the front and rear sides of the inner wall of the slot 10, and the plug 13 has limit strips 12 fixedly connected to both the front and rear sides of the plug 13. The limit strips 12 are movably connected to the inner cavity of the corresponding limit grooves 11.

[0033] In this embodiment, this setting enables the limiting operation of the insertion between the insert block 13 and the slot 10, thus ensuring a stable installation between the insert block 13 and the tool holder 9.

[0034] Among them, a sleeve 32 is sleeved on the outside of the suction pipe 26, a rack 31 is fixedly connected to the top of the sleeve 32, a gear 30 is meshed on the top of the rack 31, an L-shaped plate 27 is fixedly connected to both the front and rear sides of the vertical frame 6, a motor 28 is fixedly connected to the outside of the L-shaped plate 27, a rotating rod 29 is fixedly connected to one side of the motor 28, the end of the rotating rod 29 away from the motor 28 passes through the L-shaped plate 27 and is fixedly connected to the side wall of the corresponding gear 30, and the rotating rod 29 is movably connected to the L-shaped plate 27;

[0035] In this embodiment, this setting can drive the suction pipe 26 to swing back and forth, expand the suction range of the suction pipe 26, and thus make the suction effect better.

[0036] Among them, both collection boxes 21 are equipped with movable doors 22 on the opposite side of each other;

[0037] In this embodiment, this configuration facilitates the removal of metal debris from the suction collection box 21 for subsequent recycling.

[0038] Among them, a pump base 24 is fixedly connected to one side of the air pump 23, and the pump base 24 is fixedly connected to the side wall of the machine tool body 1;

[0039] In this embodiment, this setting enables the air pump 23 to be fixedly installed, making the subsequent operation of the air pump 23 more stable.

[0040] Working principle: In use, the workpiece is first placed inside the U-shaped plate 3. The two clamping plates 4, under the elastic force of multiple springs 5, clamp and fix the workpiece, ensuring high stability during subsequent processing and preventing misalignment. Then, the operator can drive the cylinder 8 via the control console 2, causing the bottom insert block 13 to move. The insert block 13 moves the tool holder 9, which in turn moves the bottom tool 20. After the tool 20 reaches the appropriate processing position, the cylinder 8 is closed, and the tool... 20. A series of processing operations are performed on the fixed parts. During the processing, the air pump 23 and motor 28 can be driven, so that the air pump 23 generates suction force, which sucks up the debris generated during the processing through the suction pipe 26, and then enters the collection box 21 through the guide tube 25. At the same time, the motor 28 drives the rotating rod 29 to rotate repeatedly, the rotating rod 29 drives the gear 30 to rotate repeatedly, the gear 30 drives the rack 31 to move back and forth repeatedly, the rack 31 drives the bottom sleeve 32 to move, and the sleeve 32 drives the suction pipe 26 to swing back and forth repeatedly, through the suction pipe 26. The back-and-forth swing of the 6th component expands its suction range, preventing metal debris residue from remaining and eliminating the need for manual cleaning, thus saving labor and time. The door 22 can be opened later to remove the metal debris sucked into the collection box 21 for subsequent recycling. After a period of operation, if the blade 20 becomes worn and needs replacement, the handles 15 on both sides can be pulled, causing the handles 15 to move the round rod 16. As the round rod 16 pulls out of the round groove 19, it moves the stop block 18, which compresses the second spring 17. At this point, the tool holder 9 and the bottom tool 20 can be removed from the insert block 13 to separate the tool holder 9 from the cylinder 8. Then, the operator can disassemble and replace the tool 20 at the bottom of the tool holder 9. After the replacement is completed, insert the insert block 13 at the bottom of the cylinder 8 into the slot 10 at the top of the tool holder 9. Then, release the handle 15 so that the handle 15 drives the round rod 16 to reset under the elastic force of the corresponding second spring 17. At this time, the round rod 16 is reinserted into the round groove 19 to achieve the fixing operation between the tool holder 9 and the cylinder 8, which facilitates subsequent work.
