Description
Technical Field
[0001] This utility model relates to the field of CNC lathe machining technology, specifically to a high-efficiency heat dissipation device for CNC lathes. Background Technology
[0002] CNC lathes are among the most widely used CNC machine tools. They are mainly used for cutting and machining the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and other machining operations.
[0003] When working on a CNC lathe, the workpiece generates high temperatures during high-speed grinding and cutting. These high temperatures may cause thermal deformation of the workpiece, requiring heat dissipation. Traditional heat dissipation and cooling methods often use cutting fluid. However, during the recycling process of cutting fluid, the cutting debris generated can easily clog the filter plate, thus affecting the filtration of the cutting fluid and resulting in poor cutting fluid recycling efficiency.
[0004] As disclosed in Chinese Patent CN219337033U, a rapid heat dissipation device for CNC lathes includes a frustum-shaped strainer placed on the cooling tank. This strainer automatically blocks and filters the flowing coolant and debris. The debris slides down the inclined plane and falls into the annular collection box, or is flushed into the annular collection box by the coolant. This achieves automatic filtration and collection of debris without clogging the frustum-shaped strainer. A placement component with a cross-shaped fixing bracket is placed in the placement slot to fix the position of the frustum-shaped strainer. When a large amount of debris has been collected, the cross-shaped fixing bracket can be lifted to remove the debris from the annular collection box.
[0005] The position of the upper end of the cooling delivery pipe of the heat dissipation device is fixed, so the spray trajectory of the coolant sprayed from the upper end of the cooling delivery pipe is fixed. However, the different workpieces clamped at the outer end of the clamping block have different grinding and cutting positions, so it is impossible to ensure that the coolant is accurately sprayed to the processing position of the workpiece, thus failing to guarantee the heat dissipation effect.
[0006] Therefore, we urgently need to provide a high-efficiency heat dissipation device for CNC lathes with adjustable spray position. Utility Model Content
[0007] The purpose of this invention is to provide a high-efficiency heat dissipation device for CNC lathes, in order to solve the problem mentioned in the background art that different workpieces held at the outer end of the clamping block have different grinding and cutting positions, thus making it impossible to ensure that the coolant is accurately sprayed to the machining position of the workpiece, thereby failing to guarantee the heat dissipation effect.
[0008] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency heat dissipation device for a CNC lathe, comprising a CNC lathe body and an operating table, wherein the operating table is installed on the upper left side of the CNC lathe body, a chuck is installed on the right side of the operating table, and heat dissipation mechanisms are connected to the upper and lower ends of the CNC lathe body.
[0009] The heat dissipation mechanism includes a connecting pipe fixedly connected to the lower end of the CNC lathe body. A cooling tank is fixedly connected to the lower end of the connecting pipe. A rubber tube is connected inside the cooling tank. A rectangular frame is fixedly connected to the inner right end of the operating table. A mounting plate is fixedly connected to the inner right end of the rectangular frame. A motor is installed between the inner right end of the rectangular frame and the mounting plate. A first threaded rod is fixedly connected to the left end of the motor's output shaft. An adjusting block is connected to the outer end of the first threaded rod. A connector is fixedly connected to the lower side of the adjusting block. A round shaft is fixedly connected to the inner side of the connector. A rotating rod is rotatably connected to the outer side of the round shaft. A nozzle is installed at the lower end of the inner side of the rotating rod. A second threaded rod is connected to the lower right end of the inner side of the connector. A rotating handle is welded to the right end of the second threaded rod. A filter unit is installed inside the connecting pipe.
[0010] A further improvement is that the filter unit includes a support frame fixedly connected to the inside of the connecting pipe, a sliding frame slidably connected to the inside of the connecting pipe, a V-shaped filter plate fixedly connected to the inside of the sliding frame, filter holes opened inside the filter plate, a handle fixedly connected to the upper side of the sliding frame, and baffles fixedly connected at the positions between the front and rear ends of the filter plate and the sliding frame.
[0011] A further improvement is that a rotating hole is provided at the middle of the left end inside the rectangular frame. The outer side of the left end of the first threaded rod is rotatably connected to the inner side of the rotating hole. Thus, when the motor is started and its output shaft rotates, driving the first threaded rod to rotate, the end of the first threaded rod away from the motor will rotate inside the rotating hole.
[0012] A further improvement is that a first threaded hole is laterally opened in the middle of the adjusting block, the outer side of the first threaded rod is threadedly connected to the inner side of the first threaded hole, and the front and rear sides of the adjusting block are slidably connected to the front and rear sides of the rectangular frame and the front and rear ends of the inner side of the rectangular frame. Thus, when the motor is started and its output shaft rotates, driving the first threaded rod to rotate, the adjusting block at the outer end can be driven to move along the inner side of the rectangular frame.
[0013] A further improvement is that a water pump is installed inside the cooling tank. The lower end of the rubber tube is fixedly connected to the water pump, and the upper end of the rubber tube is fixedly connected to the upper end of the nozzle. Thus, starting the water pump in the cooling tank can draw the coolant in the cooling tank into the rubber tube, and then into the nozzle from the other end, and spray it out from the lower end of the nozzle.
[0014] A further improvement is that a second threaded hole is provided at the lower right end of the connector. The outer side of the second threaded rod is threaded to the inner side of the second threaded hole. The left end of the second threaded rod abuts against the upper right end of the rotating rod. Thus, by rotating the handle, the second threaded rod rotates in the second threaded hole and moves to the left until the left end of the second threaded rod abuts against the right side of the rotating rod. Then, the rotating rod can be rotated and fixed again.
[0015] A further improvement is that the upper part of the CNC lathe body located on the right side of the operating table is recessed downwards, and a liquid collection hole is opened at the lowest end of the recess. The connecting pipe is fixed to the liquid collection hole on the lower side of the CNC lathe body, so that after the coolant sprayed by the nozzle onto the workpiece machining area falls down, it will slide down along the recessed surface of the upper end of the CNC lathe body and finally slide into the connecting pipe.
[0016] A further improvement is that the upper side of the support frame abuts against the lower side of the sliding frame, so that after the sliding frame is placed inside the connecting pipe, it will slide down to the upper side of the support frame and be supported by the support frame, thereby allowing the filter plate to be installed inside the connecting pipe.
[0017] In summary, this application discloses a high-efficiency heat dissipation device for CNC lathes.
[0018] This technical solution involves starting a motor and rotating its output shaft to move an adjusting block along the inner side of a rectangular frame until the lower nozzle moves to the upper part of the workpiece to be polished. Then, the rotating rod is rotated around the circular axis to rotate the nozzle so that its spray direction faces the workpiece polishing position. Finally, the rotating handle is rotated to move the second threaded rod to the left and fix the rotating rod again. This adjusts the spray direction of the coolant to face the workpiece polishing position. Thus, this adjustment mechanism allows the coolant to be accurately sprayed onto the workpiece polishing position, providing efficient heat dissipation for the polishing area.
[0019] Furthermore, after the CNC lathe has finished its work, by pulling up the handle, the sliding frame can be moved upward along the inside of the connecting tube, and the filter plate can be removed from the connecting tube. Then, the filter residue on the filter plate can be cleaned. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figures 1-5 This utility model provides a technical solution: a high-efficiency heat dissipation device for a CNC lathe, including a CNC lathe body 1 and an operating table 2. The operating table 2 is installed on the upper left side of the CNC lathe body 1, and a chuck 3 is installed on the right side of the operating table 2. Heat dissipation mechanisms are connected to the upper and lower ends of the CNC lathe body 1.
[0028] The heat dissipation mechanism includes a connecting pipe 401 fixedly connected to the lower end of the CNC lathe body 1. A cooling tank 402 is fixedly connected to the lower end of the connecting pipe 401. A rubber tube 403 is connected inside the cooling tank 402. A rectangular frame 404 is fixedly connected to the inner right end of the operating table 2. A mounting plate 405 is fixedly connected to the inner right end of the rectangular frame 404. A motor 406 is installed between the inner right end of the rectangular frame 404 and the mounting plate 405. A first threaded rod 407 is fixedly connected to the left end of the output shaft of the motor 406. A rotating hole is opened in the middle of the left end of the rectangular frame 404. The outer side of the left end of the first threaded rod 407 is rotatably connected to the inner side of the rotating hole. When the output shaft of the motor 406 is started and rotates, the end of the first threaded rod 407 away from the motor 406 will rotate inside the rotating hole, so that the first threaded rod 407 can maintain stable rotation.
[0029] An adjusting block 408 is connected to the outer end of the first threaded rod 407. A first threaded hole is opened laterally in the middle of the adjusting block 408. The outer side of the first threaded rod 407 is threaded to the inner side of the first threaded hole. The front and rear sides of the adjusting block 408 are slidably connected to the front and rear sides of the rectangular frame 404 and the front and rear ends of the inner side of the rectangular frame 404. When the output shaft of the motor 406 is started and rotates, it drives the first threaded rod 407 to rotate, which can drive the adjusting block 408 at the outer end to move along the inner side of the rectangular frame 404, thereby driving the nozzle 412 at the lower end to move together.
[0030] A connector 409 is fixedly connected to the lower side of the adjusting block 408. A round shaft 410 is fixedly connected to the inner side of the connector 409. A rotating rod 411 is rotatably connected to the outer side of the round shaft 410. A nozzle 412 is installed at the lower end of the inner side of the rotating rod 411. A first threaded hole is opened laterally in the middle of the interior of the adjusting block 408. The outer side of the first threaded rod 407 is threadedly connected to the inner side of the first threaded hole. The front and rear sides of the adjusting block 408 are slidably connected to the front and rear sides of the rectangular frame 404 and the front and rear ends of the inner side of the rectangular frame 404. When the output shaft of the motor 406 is started and rotates, it drives the first threaded rod 407 to rotate, which can drive the adjusting block 408 at the outer end to move along the inner side of the rectangular frame 404, thereby driving the nozzle 412 at the lower end to move together.
[0031] A water pump is installed inside the cooling tank 402. The lower end of the rubber tube 403 is fixedly connected to the water pump, and the upper end of the rubber tube 403 is fixedly connected to the upper end of the nozzle 412. By starting the water pump in the cooling tank 402, the coolant in the cooling tank 402 can be drawn into the rubber tube 403 and then enter the nozzle 412 from the other end, and sprayed out from the lower end of the nozzle 412.
[0032] A second threaded rod 413 is connected to the lower right end of the connector 409. A rotating handle 414 is welded to the right end of the second threaded rod 413. A second threaded hole is opened at the lower right end of the connector 409. The outer side of the second threaded rod 413 is threaded to the inner side of the second threaded hole. The left end of the second threaded rod 413 abuts against the upper right side of the rotating rod 411, thereby rotating the rotating rod 411 around the circular shaft 410. After the nozzle 412 rotates to a suitable spray angle, the rotating handle 414 is rotated to make the second threaded rod 413 rotate in the second threaded hole and move to the left until the left end of the second threaded rod 413 abuts against the right side of the rotating rod 411. Then the rotating rod 411 can be rotated and fixed again.
[0033] The upper part of the CNC lathe body 1 located to the right of the operating table 2 is recessed downwards, and a liquid collection hole is opened at the lowest end of the recess. The connecting pipe 401 is fixed to the liquid collection hole on the lower side of the CNC lathe body 1. After the coolant sprayed by the nozzle 412 onto the workpiece machining area falls down, it will slide down along the recessed surface of the upper end of the CNC lathe body 1 and finally slide into the connecting pipe 401. After passing through the filter plate 503 inside the connecting pipe 401, it will flow back into the cooling tank 402 for recycling.
[0034] A filter unit is installed inside the connecting pipe 401. The filter unit includes a support frame 501 fixedly connected to the inner side of the connecting pipe 401, a sliding frame 502 slidably connected to the inner side of the connecting pipe 401, a V-shaped filter plate 503 fixedly connected to the inner side of the sliding frame 502, filter holes being opened inside the filter plate 503, a handle 504 fixedly connected to the upper side of the sliding frame 502, and baffles 505 fixedly connected at the positions between the front and rear ends of the filter plate 503 and the sliding frame 502. The upper side of the support frame 501... The sliding frame 502 abuts against the lower side of the sliding frame 502, so that after the sliding frame 502 is placed inside the connecting tube 401, it will slide down to the upper side of the support frame 501 and be supported by the support frame 501, so that the filter plate 503 is installed inside the connecting tube 401. After the CNC lathe finishes working, by pulling up the handle 504, the sliding frame 502 moves up along the inner side of the connecting tube 401, and the filter plate 503 can be removed from the connecting tube 401. Then the filter residue on the filter plate 503 is cleaned.
[0035] Working principle: When machining a workpiece held on the chuck 3 of a CNC lathe, the motor 406 is started first, and its output shaft rotates to move the adjusting block 408 along the inner side of the rectangular frame 404 until the lower nozzle 412 is moved to the upper part of the workpiece to be polished. Then, the rotating rod 411 is rotated around the circular shaft 410 so that the nozzle 412 rotates to face the workpiece polishing position. Then, the rotating handle 414 is rotated so that the second threaded rod 413 moves to the left and fixes the rotating rod 411 again. Then, the CNC lathe is started to machine the workpiece. At the same time, the water pump in the cooling tank 402 is started to draw the coolant in the cooling tank 402 into the rubber tube 403, and then into the nozzle 412 from the other end. The coolant is sprayed from the lower end of the nozzle 412 to the machining position of the workpiece for cooling.
