Description

Technical Field

[0001] This utility model relates to the field of CNC tool processing technology, and in particular to a polishing and cleaning device for CNC tool processing. Background Technology

[0002] Polishing and cleaning equipment in CNC tooling is mainly used for surface treatment of tools to improve their accuracy, surface quality, and service life. This type of equipment typically includes functions such as polishing, cleaning, and deburring to remove impurities, oxides, oil, and tiny particles generated during machining from the tool surface, thus ensuring optimal tool performance. Currently, common CNC tool polishing equipment includes ultrasonic cleaning and polishing equipment. Existing ultrasonic polishing devices usually require operators to place the tools into a polishing tank, where the polishing fluid acts as an ultrasonic medium for cleaning and polishing. However, in existing devices, when multiple tools are placed in the polishing tank, they typically sink to the bottom due to gravity. This stacking reduces the contact area between the tools, significantly decreasing the contact effect between the tools and the polishing fluid, leading to poorer polishing results, longer polishing time, and reduced equipment efficiency.

[0003] The purpose of this invention is to provide a polishing and cleaning device for CNC tool processing, so as to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology mentioned in the background section by proposing a polishing and cleaning device for CNC tool processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A polishing and cleaning device for CNC tool processing includes a polishing mechanism, a rotating shaft, and a fixture. The rotating shaft is fitted inside the polishing mechanism, and a support roller is fitted outside the rotating shaft. A connecting rod extends from the outside of the support roller, and a connecting plate is fixedly connected to the upper end of the connecting rod. A fixture is fitted to the upper end of the connecting plate, and a cover plate is fitted to the upper end of the fixture. A knob is fitted to the upper surface of the fixture. Clamping plates are fixedly connected to the left and right ends of the cover plate. Multiple tool insertion holes are fixedly installed inside the fixture.

[0007] Preferably, the upper surface of the connecting plate is provided with a pin, and the inside of the pin is provided with a slot. Multiple extrusion rods are fixedly installed at the bottom of the cover plate. The inner ends of the clamp are provided with slots corresponding to the positions of the clamping plate. The inner side of the tool insertion hole is provided with an extrusion groove. The bottom of the clamp is provided with a locking pin, and the upper end of the locking pin passes through the clamp and is engaged with the knob.

[0008] Preferably, the overall size of the extrusion rod is the same as the size of the groove opened in the extrusion groove, and the extrusion rod, the extrusion groove and the tool insertion hole are all made of rubber.

[0009] Preferably, the knob is composed of a knob, a second connecting rod, and a return spring sleeve on the outside of the connecting rod, and the surface of the knob is provided with a rubber sleeve.

[0010] Preferably, the lower inner end of the pin is provided with slots on both the left and right sides, and the openings of the slots at both ends are opposite.

[0011] Preferably, the connecting plate is a rectangular plate with a rectangular groove in the middle, and the fixture is composed of a connecting rectangular plate and a tool storage fixture, and the connecting plate and the rectangular plate on the outside of the fixture are the same size.

[0012] Preferably, the cover plate is rectangular in shape, and all four sides of the cover plate are provided with sealing strips.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By setting a rotating shaft and a clamp, the cutting tools of this device can be arranged in the polishing tank through the clamp, avoiding the stacking of tools at the bottom. At the same time, the cutting tools can remain in a moving state in the polishing tank during the polishing operation. This design effectively increases the contact area between the cutting tools and the polishing liquid. Furthermore, by constantly swinging the cutting tools back and forth in the tank, they can contact the polishing liquid at multiple angles, thereby improving the impact force and grinding effect of the polishing liquid on the tool surface. This dynamic movement not only promotes full contact between the polishing liquid and the cutting tools, but also enhances the polishing efficiency, ensuring uniform and efficient polishing treatment of the tool surface.

[0015] 2. By setting up a clamp and cover plate, when it is necessary to remove and replace the tool inside the clamp, the operator can press the clamp plate to remove the cover plate from the surface of the clamp, thereby exposing the tool inside the clamp. At this time, the operator can take the tool out of the clamp for replacement. This design simplifies the tool replacement process. In addition, the operator can quickly fix the clamp to the surface of the connecting plate by using the knob on the surface of the clamp, reducing the installation time of the clamp.

[0028] Example

[0029] Reference Figure 1-7 A polishing and cleaning device for CNC tool processing includes a polishing mechanism 1, a rotating shaft 2, and a fixture 3. The polishing mechanism 1 consists of a polishing tank and an operating table. The bottom of the polishing tank is located inside the polishing mechanism 1 and is equipped with an ultrasonic generator and an ultrasonic transducer. The rotating shaft 2 is located inside the polishing tank, and one end of the rotating shaft 2 is fitted and connected to the inner wall of the polishing tank. A servo motor is fitted and connected to the outer surface of the polishing mechanism 1 corresponding to the position of the rotating shaft 2. A sealing sleeve is provided at the connection between the rotating shaft 2 and the inner wall of the polishing tank. The sealing sleeve can prevent the polishing liquid inside the polishing tank from flowing out from the gap between the rotating shaft 2 and the inner wall of the polishing mechanism 1. When polishing the tool, the operator can start the ultrasonic generator through an external controller or the operating table. The generator converts electrical energy into high-frequency vibration. Then, the polishing liquid in the polishing tank acts as a medium to transmit ultrasonic vibration. It can also help clean the tool surface and remove impurities or burrs from the tool surface, thereby completing the tool polishing operation.

[0030] The polishing mechanism 1 has a rotating shaft 2 fitted inside, and a support roller 5 fitted outside. A connecting rod extends from the outside of the support roller 5, and a connecting plate 6 is fixedly connected to the upper end of the connecting rod. A clamp 3 is fitted to the upper end of the connecting plate 6, and a cover plate 4 is fitted to the upper end of the clamp 3. A knob 8 is fitted to the upper surface of the clamp 3. A retaining plate 9 is fixedly connected to the left and right ends of the cover plate 4. Multiple tool insertion holes 10 are fixedly installed inside the clamp 3. With this design, the operator can fix the tool inside the clamp 3 and then install the clamp 3 inside the connecting plate 6. In this way, when the tool is inside the polishing tank for polishing, the servo motor can drive the rotating shaft 2 to reciprocate through the transmission shaft, so that the tool can be in an active state in the polishing tank during the polishing process. This design increases the contact area between the tool and the polishing liquid and enriches the angle at which the tool receives the impact of the polishing liquid, thereby enhancing the polishing efficiency of the tool.

[0031] It should be noted that when the rotating shaft 2 reciprocates, it can drive the connecting plate 6 to swing through the connecting rod. Furthermore, by programming the servo motor, the included angle between the maximum swing positions on the left and right sides of the connecting plate 6 is not greater than 60 degrees. This can prevent the connecting plate 6 from colliding with the inner wall of the polishing mechanism 1 during the swing process.

[0032] A pin 7 is provided on the upper surface of the connecting plate 6, and a slot 14 is provided inside the pin 7. Multiple pressing rods 11 are fixedly installed on the bottom of the cover plate 4. The inner ends of the clamp 3 are provided with slots 15 corresponding to the positions of the clamping plate 9. The inner side of the tool insertion hole 10 is provided with a pressing groove 12. The bottom of the clamp 3 is provided with a locking pin 13, and the upper end of the locking pin 13 passes through the clamp 3 and is engaged with the knob 8. With this design, when the operator installs the tool inside the clamp 3, the operator can press the clamping plate 9 to disengage the buckle on the side of the clamping plate 9 from the slot 15, and then remove the cover plate 4 from the top of the clamp 3. After the cover plate 4 is in place, the operator can insert the tool into the tool insertion hole 10 inside the fixture 3, so that the cutting section of the tool is exposed at the bottom of the fixture 3 through the tool insertion hole 10. Then the operator can close the cover plate 4 on the upper surface of the fixture 3. During this process, the buckle on the side of the clamping plate 9 can automatically engage into the slot 15 to complete the fixation. When the cover plate 4 is closed on the upper surface of the fixture 3, the extrusion rod 11 at the bottom of the cover plate 4 will be inserted into the inside of the tool insertion hole 10 until it is limited by the extrusion groove 12. In this way, the extrusion rod 11 can limit the tool from the upper end of the tool insertion hole 10, preventing the tool from falling off during the polishing process.

[0033] It should be noted that the overall latch plate 9 is similar to the latch of the battery compartment cover of an air conditioner remote control. By setting the latch slots 15 on both sides of the clamp 3 corresponding to the latch plate 9, the operation of opening and closing the cover plate 4 is similar to the process of opening the battery compartment cover of a remote control.

[0034] The overall size of the extrusion rod 11 is the same as the size of the groove opened in the extrusion groove 12. The extrusion rod 11, the extrusion groove 12 and the tool insertion hole 10 are all made of rubber. Through this design, the extrusion rod 11, the extrusion groove 12 and the tool insertion hole 10 can avoid damage to the tool mounting port during the process of limiting the tool.

[0035] The knob 8 consists of a knob, a second connecting rod, and a return spring sleeve on the outside of the connecting rod. The surface of the knob 8 is covered with a rubber sleeve. The lower end of the pin 7 has slots 14 on both the left and right sides, and the openings of the slots 14 at both ends are opposite. When the clamp 3 is fixed to the upper end of the connecting plate 6, the operator can press the knob 8 to insert the locking pin 13 into the lower end of the pin 7. At this time, the operator can rotate the knob 8 to make the locking pin 13 rotate and lock into the inside of the slot 14, thereby fixing the clamp 3 to the upper surface of the connecting plate 6. After polishing, the operator can rotate the knob 8 to make the locking pin 13 rotate out of the slot 14. Then, the return spring at the bottom of the knob 8 will pop the knob 8 out. During this process, the locking pin 13 moves upward and disengages from the pin 7. At this time, the operator can remove the clamp 3 from the upper surface of the connecting plate 6.

[0036] The connecting plate 6 is a rectangular plate with a rectangular groove in the middle. The fixture 3 is composed of a connecting rectangular plate and a tool storage fixture. The rectangular plates on the outside of the connecting plate 6 and the fixture 3 are the same size. With this design, when the fixture 3 is covered on the upper surface of the connecting plate 6, the tool storage fixture at the lower end of the fixture 3 can pass through the connecting plate 6. After the fixture 3 is installed on the surface of the connecting plate 6, the tool storage fixture and the tool can be located in the polishing liquid.

[0037] The cover plate 4 is rectangular in shape, and all four sides of the cover plate 4 are provided with sealing strips. This design allows the sealing strips on the four sides of the cover plate 4 to prevent polishing liquid from flowing into the interior of the clamp 3 from the connection between the cover plate 4 and the clamp 3 during polishing operations.

[0038] Working Principle: During tool polishing, the operator can activate the ultrasonic generator via an external controller or control panel. The generator converts electrical energy into high-frequency vibrations. The polishing fluid in the polishing tank then acts as a medium to transmit these ultrasonic vibrations, which also assist in cleaning the tool surface, removing impurities or burrs. While the tool is being polished inside the polishing tank, a servo motor drives the rotating shaft 2 to reciprocate via a drive shaft. This allows the tool to remain in motion within the polishing tank during the polishing process. This design enhances the contact area between the tool and the polishing fluid and expands the angle at which the tool receives the impact of the polishing fluid, thereby increasing the polishing efficiency. When the operator needs to change the polishing tool, they can press the retaining plate 9 to... The buckles on the side of the clamping plate 9 disengage from the slot 15, and then the cover plate 4 is removed from the top of the fixture 3. After removing the cover plate 4, the operator can take out the polished tool, and then insert the unpolished tool into the tool insertion hole 10 inside the fixture 3, so that the cutting section of the tool is exposed at the bottom of the fixture 3 through the tool insertion hole 10. Then the operator can close the cover plate 4 on the upper surface of the fixture 3. During this process, the buckles on the side of the clamping plate 9 can automatically engage into the slot 15 to complete the fixation. When the cover plate 4 is closed on the upper surface of the fixture 3, the pressing rod 11 at the bottom of the cover plate 4 will be inserted into the inside of the tool insertion hole 10 until it is limited by the pressing groove 12. In this way, the pressing rod 11 can limit the tool from the top of the tool insertion hole 10, preventing the tool from falling off during the polishing process.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.

[0040] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
