Description

Technical Field

[0001] This utility model relates to the field of bar processing technology, specifically to a dust removal mechanism for a precision CNC lathe based on bar processing. Background Technology

[0002] CNC lathe is short for digital control lathe. It is an automated lathe equipped with a program control system. It can control the movement of the cutting tool according to the pre-programmed program to realize the automatic machining of rotating workpieces. CNC lathes are usually used when machining bar stock into bushings, shafts and crank products.

[0003] When existing CNC lathes are in operation, the operator usually fixes the bar stock in the CNC lathe with a fixture, and then drives the bar stock to rotate. The program controls the movement of the cutting tool to process the bar stock. Some lathes use a vacuum cleaner to remove the dust generated during processing, while some CNC lathes do not have an independent dust collection component. After the bar stock is processed, the operator uses an external vacuum cleaner to clean the inside of the CNC lathe.

[0004] Existing CNC lathes have the following problems: the former uses a vacuum cleaner to suck up metal dust, but when the sucked-up metal dust particles are large, they may clog the vacuum cleaner, and the vacuum cleaner nozzle is usually fixed in one place, resulting in poor dust removal effect; the latter, although cleaned afterward, creates a harsh working environment that affects the physical and mental health of employees. Therefore, we propose a dust removal mechanism for precision CNC lathes based on bar machining. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a dust removal mechanism for a precision CNC lathe based on bar processing. The dust removal mechanism effectively removes metal dust generated during bar processing, and the metal dust is intercepted by the filter screen, avoiding the impact of large metal dust particles on the normal operation of the dust collection work. In addition, the feed funnel at the feed end of the dust collection pipe always moves with the tool, which improves the dust collection effect and can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust removal mechanism for a precision CNC lathe based on bar processing, including a lathe, an adjustable tool holder inside the lathe, and a dust removal mechanism;

[0007] Dust removal mechanism: It includes a dust collection box, a fan, a dust collection pipe, a feed funnel, a filter screen, and a fixing assembly. The dust collection box is installed in the mounting slot on the left side of the lathe. The fan is installed in the mounting hole on the front side of the dust collection box. The dust collection pipe is installed at the feed inlet on the right side of the dust collection box. The upper end of the dust collection pipe passes through the rear end of the tool holder and is connected to the feed funnel. Sufficient length of dust collection pipe is reserved between the dust collection box and the tool holder. The filter screen is installed inside the dust collection box in cooperation with the fixing assembly. The dust removal mechanism effectively removes metal dust generated during the bar processing. The filter screen intercepts the metal dust, avoiding the impact of large metal dust particles on the normal operation of the dust collection work. Moreover, the feed funnel at the feed end of the dust collection pipe always moves with the tool, improving the dust collection efficiency.

[0008] Furthermore, it also includes a microcontroller, which is fixedly connected to the front side of the lathe. The input terminal of the microcontroller is electrically connected to an external power source, and the input terminal of the fan is electrically connected to the output terminal of the microcontroller, which facilitates the normal operation of the equipment.

[0009] Furthermore, the dust removal mechanism also includes a limiting groove, a mounting frame, and a sealing sleeve. The upper and lower walls of the dust collection box are provided with limiting grooves, and a mounting frame is slidably connected between the two limiting grooves. The mounting frame is provided with a filter screen inside, and a sealing sleeve is fixedly fitted on the left end of the outer surface of the mounting frame to facilitate the installation of the filter screen.

[0010] Furthermore, the fixing component includes a U-shaped groove, a pin, and a handle. The front and rear sides of the left side of the dust collection box are provided with U-shaped grooves, and a pin is inserted into the slots of the two U-shaped grooves. The left side of the mounting bracket is provided with a handle to facilitate fixing the filter screen.

[0011] Furthermore, the lathe is equipped with a support frame inside, a tool holder is slidably connected to the upper surface of the support frame, a lead screw is rotatably connected to the front side of the support frame, the front end of the tool holder is threadedly connected to the outer surface of the lead screw, the lathe is equipped with a motor inside, the right end of the motor's output shaft is fixedly connected to the left end of the lead screw, and the input end of the motor is electrically connected to the output end of the microcontroller, so as to facilitate the movement of the feed end of the dust collection pipe along with the tool.

[0012] Furthermore, the lathe has grooves on both the upper and lower sides of the opening on the front side, and a protective door is slidably connected between the two grooves. The front side of the protective door has an observation window to facilitate isolation from the outside world during processing.

[0013] Furthermore, the lathe has a discharge port on its bottom wall, which is a bucket-shaped structure that is wider at the top and narrower at the bottom. A storage compartment is provided on the front side of the lathe, which is connected to the discharge port. A collection box is slidably connected inside the storage compartment to facilitate the collection of larger metal scraps.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This dust removal mechanism for a precision CNC lathe based on bar machining has the following advantages:

[0015] The blower draws the metal dust generated during the processing of the bar stock into the dust collection box through the feed funnel and the dust collection pipe. The airflow passes through the filter screen and exits the dust collection box, while the metal dust is trapped in the dust collection box by the filter screen. This effectively removes the metal dust generated during the bar stock processing. By intercepting the metal dust through the filter screen, the normal operation of the dust collection work is avoided due to the large size of the metal dust particles. In addition, the dust collection pipe moves with the tool holder during the processing of the bar stock, which improves the efficiency of the dust collection work. Attached Figure Description

When the operator pulls the protective door 9, it moves to the left along the slide groove 8. The lathe is moved to open the lathe 1, and the bar is fixed inside the lathe 1 by the three-jaw chuck. The appropriate cutting tool is installed on the tool holder 2, and then the protective door is closed. The programmed program is input into the microcontroller 2.

[0023] Dust removal mechanism 3 includes a dust collection box 31, a fan 32, a dust suction pipe 33, a feed funnel 34, a filter screen 37, and a fixing assembly 39. (The left side of the dust collection box 31 is hinged to a door, and the right side of the door is equipped with a sealing strip to ensure the door is sealed when closed. A door lock is provided at the junction of the door and the dust collection box 31, and the door lock is a common type of door lock used in the prior art.) The dust collection box 31 is installed in a mounting slot on the left side of the lathe 1. The fan 32 is installed in the mounting hole on the front side of the dust collection box 31. The right side of the dust collection box 31... A dust collection pipe 33 is provided at the feed inlet. The upper end of the dust collection pipe 33 passes through the rear end of the cutter holder 5 and is provided with a feed funnel 34. A sufficiently long dust collection pipe 33 is reserved between the dust collection box 31 and the cutter holder 5. A filter screen 37 is installed inside the dust collection box 31 in cooperation with the fixing component 39. The dust removal mechanism 3 also includes a limiting groove 35, a mounting bracket 36 and a sealing sleeve 38. The upper and lower walls of the dust collection box 31 are provided with limiting grooves 35. A mounting bracket 36 is slidably connected between the two limiting grooves 35. A filter screen 37 is provided inside the mounting bracket 36. The left end of the outer surface of the mounting bracket 36 The fixing sleeve is equipped with a sealing rubber sleeve 38. The fixing component 39 includes a U-shaped groove 391, a pin 392, and a handle 393. The dust collection box 31 has U-shaped grooves 391 on both the front and rear sides of the left side. A pin 392 is inserted into the socket of the two U-shaped grooves 391. The mounting bracket 36 has a handle 393 on the left side. At the same time, metal dust and metal chips are generated during the processing. When the fan 32 is turned on, the fan 32 draws the metal dust generated during the processing of the bar into the dust collection box 31 through the feed funnel 34 and the dust suction pipe 33. The airflow passes through the filter screen 3. Dust collection box 31 is discharged, while metal dust is blocked and retained in dust collection box 31 by filter screen 37. After the lathe 1 has been working for a period of time, the operator can open the switch door to clean the metal dust collected inside dust collection box 31. When it is necessary to clean filter screen 37, pull out the pin 392 in U-shaped groove 391, and then pull handle 393 to drive filter screen 37 to move along limit groove 35 through mounting bracket 36, so as to take out filter screen 7 for cleaning. During the process of the tool processing the bar, the dust collection pipe 33 moves with the tool holder 5, which improves the dust collection effect.

[0024] The working principle of the dust removal mechanism for a precision CNC lathe based on bar machining provided by this utility model is as follows: The operator pulls the protective door 9 to move it to the left along the slide 8, thereby opening the lathe 1. Then, the bar is fixed inside the lathe 1 by a three-jaw chuck. A suitable cutting tool is installed on the tool holder 2. Then, the protective door is closed, and the programmed code is input into the microcontroller 2. The microcontroller 2 can then drive the lead screw 6 to rotate via the motor 7 according to the programmed code, thereby controlling the movement of the cutting tool via the tool holder 5 and controlling the rotation of the bar via the three-jaw chuck, thus realizing the machining of the bar. At the same time, metal dust and metal chips are generated during the machining process. The fan 32 is turned on, and the fan 32 sucks the metal dust generated during the machining of the bar into the dust collection box 31 through the feed funnel 34 and the dust suction pipe 33. Airflow passes through filter screen 37 and exits dust collection box 31, while metal dust is blocked by filter screen 37 and remains in dust collection box 31. After the lathe 1 has been working for a period of time, the operator can open the switch door to clean the metal dust collected inside the dust collection box 31. When the filter screen 37 needs to be cleaned, the pin 392 in the U-shaped groove 391 is pulled out, and then the handle 393 is pulled to move the filter screen 37 along the limit groove 35 through the mounting bracket 36, so that the filter screen 7 can be taken out for cleaning. During the process of the tool processing the bar, the dust collection pipe 33 moves with the tool holder 5, which improves the dust collection effect. Larger metal chips generated during the processing fall into the collection box 11 through the drop port 12 under the action of their own gravity. During the processing, the operator can watch the processing through the observation window 10.

[0025] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an EFR32MG21, the fan 32 can be an SF6-4, and the motor 7 can be a YP-100. The microcontroller 2 controls the operation of the fan 32 and the motor 7 using methods commonly used in the prior art.
