Description

Technical Field

[0001] This utility model relates to the field of CNC machining technology, specifically a chip cleaning device for drilling and tapping tool holders. Background Technology

[0002] Drilling and tapping machine tools, as a key component of modern CNC machining centers, are widely used for high-speed, high-precision machining of various metal parts due to their high rotational speed, fast traverse speed, and excellent dynamic response characteristics. These products have extremely stringent requirements for machining accuracy and surface quality. However, during high-speed cutting, the generated fine metal chips are easily splashed by coolant or airflow and adhere to the tapered surface of the tool holder of the tool in the tool magazine. When the spindle performs tool changes and clamping, these tiny metal chips adhering to the tapered surface of the tool holder may become trapped between the spindle's inner taper hole and the tapered surface of the tool holder. This not only leads to insufficient tool clamping force but also causes vibration or micro-displacement of the tool during machining.

[0003] Chinese utility model patent CN219152301U discloses a cleaning device for the conical surface of a CNC machining center drilling and tapping machine. This device mainly includes a bracket mounted on the tool magazine side, a nozzle mounted on the bracket, a water pump connected to the nozzle, and a collection cylinder located below the nozzle. Its working principle is as follows: when cleaning the tool holder is required, the water pump is activated, spraying a special cleaning solution onto the conical surface of the tool holder through the nozzle. The impact force of the liquid flow carries away the attached chips. The sprayed liquid and any residue it carries fall into the collection cylinder below for collection, preventing secondary contamination. However, the cleaning effect of this device is highly dependent on the coverage area of ​​the liquid sprayed by the nozzle. Because the nozzle position is fixed and usually faces a specific area of ​​the conical surface of the tool holder, the attached chips in the conical area "behind" or to the side of the nozzle's spray trajectory are difficult to be effectively washed away. These residual tiny debris may still be carried into the spindle taper hole during subsequent tool clamping, leading to the aforementioned clamping accuracy problem, which greatly reduces the cleaning effect and fails to completely solve the accuracy risks caused by debris stuck on the tool holder taper.

[0004] Based on this, a chip cleaning device for drill and tap shanks is provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-5 As shown, a chip cleaning device for drilling and tapping tool holders includes a mounting plate 11 and clamping components. The mounting plate 11 has a plurality of clamping components arranged in an array. A connecting seat 16 is fixedly mounted on the bottom end of the mounting plate 11. A rotating ring is rotatably mounted on the connecting seat 16. The rotating ring is fixedly mounted on the upper end of a fixed seat 17, which is fixedly mounted inside the bottom end of a storage cylinder 18. The clamping components include symmetrically arranged clamping frames 12, each of which is slidably mounted on a guide frame 13. The guide frames 13 are all fixedly mounted on the upper end of the mounting plate 11. A first fixing plate is fixedly installed in the middle of the frame 13. A tension spring 14 is provided between one side of the first fixing plate and the mounting groove on one side of the clamping frame 12. A filter screen 21 is provided inside the storage cylinder 18. A drain pipe 22 is connected to the bottom end of the storage cylinder 18. A cleaning component and a drying component are arranged sequentially along the rotation direction of the mounting plate 11 at the upper end of the storage cylinder 18. A rotating mechanism is provided at the bottom end of the mounting plate 11 to drive the drill and tap handle 24 to rotate. The rotating mechanism facilitates the rotation of the drill and tap handle 24, thereby enabling the drill and tap handle 24 to be cleaned at an angle.

[0025] An internal spline shaft is fixedly provided at the bottom of the connecting seat 16. An external spline shaft 19 is fitted inside the internal spline shaft. The external spline shaft 19 is fixedly provided at the output end of the motor 20. The motor 20 is fixedly provided inside the fixing seat 17. The motor 20 is electrically connected to the control component 36. The control component 36 is fixedly provided on the outside of the storage cylinder 18. When it is necessary to clean the drill and tap shank 24, the motor 20 is started by controlling the control component 36. The motor 20 drives the connecting seat 16 to rotate intermittently, so that the drill and tap shank 24 can be cleaned by the cleaning component.

[0026] Each clamping frame 12 has a second fixing plate fixed at one end. Each of the upper ends of the second fixing plate is hinged with a scraper 35. Each of the other ends of the scraper 35 is hinged with a hinge seat. Each hinge seat is fixed on a fixing plate. Each fixing plate has a guide slide rod slidably mounted in the middle. The guide slide rod is fixed on the upper end of the first fixing plate. In use, when it is necessary to clamp and fix the drill and tap handle 24, the user presses the fixing plate. The fixing plate slides along the axis of the guide slide rod. The fixing plate drives the clamping frame 12 to slide through the scraper 35, placing the drill and tap handle 24 between the two clamping frames 12. Then, the fixing plate is released. Under the action of the tension spring 14, the two clamping frames 12 clamp and fix the drill and tap handle 24.

[0027] The cleaning component includes cleaning nozzles 23, with a plurality of cleaning nozzles 23 arranged in an equally spaced array. Each cleaning nozzle 23 is fixedly mounted with a support frame, which is fixedly mounted on the upper end of the storage cylinder 18. Each cleaning nozzle 23 is connected to a connecting pipe 25, which is fixedly mounted on the upper end of the support frames. The input end of the connecting pipe 25 is connected to one end of a first delivery pipe, and the other end of the first delivery pipe is connected to the output end of a liquid pump 26. The liquid pump 26 is fixedly mounted on the upper end of a liquid storage tank 27, and its input end is connected to the liquid storage tank 27. The internal structure of the box 27 is interconnected. During use, after the clamping frame 12 clamps and fixes the drill bit holder 24, the mounting plate 11 moves the drill bit holder 24 to below the cleaning nozzle 23 and then stops. Subsequently, the control component 36 controls the liquid pump 26 to start. The output end of the liquid pump 26 draws the cleaning fluid from the storage tank 27. The liquid pump 26 delivers the cleaning fluid to the inside of the connecting pipe 25. The connecting pipe 25 delivers the cleaning fluid to the inside of several cleaning nozzles 23. The cleaning nozzles 23 discharge the cleaning fluid, thus cleaning the outside of the drill bit holder 24. The spray holes of the cleaning nozzles 23 are all set at an angle.

[0028] The drying component includes a drying head 28, which is fixedly mounted at one end of a second conveying pipe. The second conveying pipe is fixedly mounted outside the receiving cylinder 18, and the other end of the second conveying pipe is connected to the output end of a fan 29. The fan 29 is fixedly mounted outside the receiving cylinder 18. Several air outlets of the drying head 28 are arranged at an angle. In use, after the drill bit holder 24 is cleaned and rotated to a position below the drying head 28, the fan 29 is started. The fan 29 delivers gas into the drying head 28, and the drying head 28 discharges the gas, thereby drying the drill bit holder 24.

[0029] The rotating mechanism includes a transmission belt 30. Each clamping component has a transmission belt 30 fitted below it. Both ends of the transmission belt 30 are fitted with drive rollers and transmission rollers, which are rotatably mounted inside a fixed frame. The fixed frame is fixed to the bottom of the mounting plate 11. One end of the transmission belt 30 is in close contact with the end of the drill bit holder 24. Gears 31 are fixedly mounted on the rotating shaft at one end of each drive roller. Several gears 31 mesh with gear rings 32, which are fixed to one end of a fixed base 17. The clamping frame 12 has mounting grooves on its inner side. The mounting slots are each equipped with a number of rotating rollers 33. The upper end of each clamping frame 12 is fixed with a support rod 34. The upper end of each support rod 34 is equipped with a number of balls. In use, when the clamping frame 12 clamps and fixes the drill and tap handle 24, one end of the drill and tap handle 24 is in close contact with the transmission belt 30. When the mounting plate 11 rotates, the gear 31 meshes with the gear ring 32, so that the gear 31 drives the drive roller to rotate. The drive roller and the transmission roller cooperate to drive the transmission belt 30 to rotate. The transmission belt 30 drives the drill and tap handle 24 to rotate, thereby facilitating multi-angle cleaning of the drill and tap handle 24.

[0030] The filter screen 21 is closely attached to the upper end of the connecting rod 15, which is fixedly mounted on the bottom end of the mounting plate 11. The storage cylinder 18 is connected to the slag discharge pipe at the position corresponding to the upper end of the filter screen 21. In use, when the mounting plate 11 rotates, the mounting plate 11 drives the connecting rod 15 to rotate, and the connecting rod 15 scrapes the debris at the upper end of the filter screen 21. When the debris moves to the position of the slag discharge pipe, the debris is discharged.

[0031] The above embodiment discloses a chip cleaning device for a drill bit holder. When the drill bit holder 24 needs to be clamped and fixed, the user presses the fixing plate, which slides along the axis of the guide slide rod. The fixing plate drives the clamping frame 12 to slide via the scraper 35, placing the drill bit holder 24 between the two clamping frames 12. Then, the fixing plate is released, and under the action of the tension spring 14, the two clamping frames 12 clamp and fix the drill bit holder 24. One end of the drill bit holder 24 is tightly attached to the transmission belt 30. When cleaning the drill bit holder 24 is required, the control unit 36 ​​controls the motor 20 to start. The motor 20 drives the connecting seat 16 to rotate intermittently. The mounting plate 11 moves the drill bit holder 24 to below the cleaning nozzle 23 and then stops. The control unit then... When component 36 starts the control pump 26, the output end of the pump 26 draws cleaning fluid from the storage tank 27. The pump 26 delivers the cleaning fluid to the connecting pipe 25, which in turn delivers it to several cleaning nozzles 23. The cleaning nozzles 23 discharge the cleaning fluid, thus cleaning the outside of the drill bit holder 24. Simultaneously, when the mounting plate 11 rotates, the gear 31 meshes with the gear ring 32, causing the gear 31 to drive the drive roller to rotate. The drive roller, in conjunction with the transmission roller, drives the transmission belt 30 to rotate, which in turn drives the drill bit holder 24 to rotate. After the drill bit holder 24 is cleaned, it rotates to a position below the drying head 28, at which point the blower 29 is started. The blower 29 delivers gas into the drying head 28, which then discharges the gas, thereby drying the drill bit holder 24.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
