[0002] In CNC lathe machining, tool setting is a crucial step in ensuring machining accuracy. Traditional tool setting devices typically detect tool position through sensors or mechanical contact to establish the coordinate system. However, debris generated during machining easily adheres to the tool setter, leading to a decrease in tool setting accuracy and consequently, machining errors. Therefore, there is an urgent need for an automatic tool setting device that can automatically clean the tool setter to improve tool setting accuracy.

[0003] In traditional CNC lathes, automatic tool setting devices are prone to chipping and adhering to the tool setter during machining, contaminating the tool setting contact surface and affecting detection accuracy. This problem typically causes tool setting errors, thereby reducing machining accuracy and impacting overall machining quality. Therefore, effectively cleaning the chip setter and improving tool setting precision has become a pressing technical challenge. Utility Model Content

Detailed Implementation

[0018] 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.

[0019] See Figure 1 This utility model embodiment shows an automatic tool setting device for a CNC lathe, including a base 1, a drive box 2, a cleaning component 3, a tool setting component 4, a tool head component 5, and a fixing clamp 6. The upper end of the base 1 is fixedly connected to the drive box 2, the fixing clamp 6 is fixedly connected to one side of the drive box 2, the tool setting component 4 and the cleaning component 3 are rotatably connected to one side of the drive box 2, and the tool head component 4 is fixedly connected to the base 1 and is arranged adjacent to the tool setting component 4. The cleaning component 3 includes a first connecting rod 31, a connecting block 32, a clamping plate 33, and a jet nozzle 34. One end of the first connecting rod 31 is rotatably connected to one side of the drive box 2, and the other end of the first connecting rod 31 is fixedly connected to one end of the connecting block 32. The other end of the connecting block 32 is fixedly connected to the clamping plate 33, and the clamping plate 33 is rotatably connected to the jet nozzle 34. The jet nozzle pipe is connected to high-pressure gas.

[0020] In this embodiment, the fixing clamp 6 is used to hold the blank so that it can be processed by the cutting tool. The tool setting assembly 4 and the cleaning assembly 3 work together through the drive box 2 to achieve integrated tool setting and cleaning operation. The cleaning assembly 3 uses the first connecting rod 31 to drive the connecting block 32 and the clamping plate 33 to rotate, so that the air nozzle 34 is precisely positioned in the tool setting area. High-pressure gas is sprayed through the pipeline to form a directional airflow, which effectively removes the debris deposited during the tool setting process, realizing non-contact dynamic cleaning and avoiding debris from interfering with the tool setting accuracy.

[0021] In some embodiments, the tool setting assembly 4 includes a second connecting rod 41, a clamp 42, and a tool setting device 43. One end of the second connecting rod 41 is rotatably connected to the drive box 2, and the other end of the second connecting rod 41 is fixedly connected to the clamp 42. The clamp 42 clamps and fixes the tool setting device 43.

[0022] In this embodiment, the second connecting rod 41 is rotated by the drive box 2, which drives the fixture 42 and the tool setter 43 to move precisely, thus realizing the tool setting function. When the CNC lathe needs to measure the tool position, the drive box 2 controls the second connecting rod 41 to swing, so that the tool setter 43 contacts the cutting edge of the tool head assembly 5, and the tool coordinates are determined by electrical signal feedback. The rigidly connected fixture 42 ensures stable clamping of the tool setter 43 and avoids measurement deviation.

[0023] In some embodiments, a limiting plate 44 and a limiting block 45 are provided between the second connecting rod 41 and the clamp 42. The other end of the second connecting rod 41 is fixedly connected to the limiting plate 44, the limiting plate 44 is slidably connected to the limiting block 45, and the limiting block 44 is fixedly connected to the clamp 42.

[0024] In this embodiment, by setting a limiting plate 44 and a limiting block 45 between the second connecting rod 41 and the clamp 42, the limiting plate 44 rotates with the second connecting rod 41 and, through sliding cooperation with the limiting block 45, constrains the movement range of the clamp 42, prevents the tool setter 43 from overtravel and colliding, and improves the stability and safety of the tool setting process.

[0025] In some embodiments, a rubber pad 46 is provided at the clamping point of the clamp 42 and the tool setter 43 to improve the clamping force of the clamp 42 on the tool setter 43 and the buffer protection effect.

[0026] In some embodiments, the clamp 42 includes an upper clamp 421, a lower clamp 422, and a threaded rod 423. Both the upper clamp 421 and the lower clamp 422 are provided with alignment threaded holes, and the threaded rod 423 is threaded into the threaded holes. This threaded connection allows for adjustment of the clamping force and facilitates the replacement of the tool setter 43.

[0027] In some embodiments, a knob 424 is provided at one end of the threaded rod 423, and a shim 425 is provided between the knob 424 and the clamp 42 to buffer pressure and prevent deflection, thereby ensuring stable fixation of the tool setter 43, improving clamping accuracy and ease of operation.

[0028] In some embodiments, the cutter head assembly 5 includes a guide rail 51, a movable seat 52, and a cutter head 53. The guide rail 51 is fixedly connected to the base 1, the guide rail 51 is slidably connected to the movable seat 52, and the cutter head 53 is connected to the movable seat 52.

[0029] In this embodiment, the precise movement of the cutter head 53 is achieved through the sliding cooperation between the guide rail 51 and the moving seat 52. The guide rail 51 is fixed on the base 1 to ensure stability, enabling the cutter head 53 to cut with high precision along the set path, thereby improving processing efficiency and positioning accuracy.

[0030] In some embodiments, an electric slide rail 54 and a clamping plate 55 are provided between the movable seat 52 and the cutter head 53. The movable seat 52 is fixedly connected to the electric slide rail 54, the electric slide rail 54 is slidably connected to the clamping plate 55, and the cutter head 53 is fixedly connected to the clamping plate 55.

[0031] In this embodiment, the electric slide rail 54 drives the chuck 55 to move the cutter head 53 precisely, thereby achieving efficient adjustment of the cutter head position; the chuck 55 ensures the cutter head is stably fixed, enhancing machining reliability.

[0032] In some embodiments, the movable seat 52 is provided with an electric slider 56, a guide rod 57 and a limiter 58 on both sides. The limiter 58 is sleeved on the guide rod 57 and fixedly connected to the guide rail 51. The electric slider 56 is slidably connected to the guide rod 57.

[0033] In this embodiment, the moving seat 52 is driven to slide along the guide rod 57 by the electric slider 56, and the limiter 58 ensures that the stroke is controllable, so as to achieve high-precision positioning and stable movement of the cutter head 53, improve processing efficiency and prevent overtravel damage to the equipment.

[0034] In some embodiments, the base 1 is fixedly connected to an isolation cover 11 that covers the cleaning component 3, the tool setting component 4, and the tool head component 5, and the isolation cover 11 is rotatably connected to an observation cover 12. The isolation cover 11 is used to seal off key components and prevent debris from splashing, while the observation cover 12 facilitates real-time monitoring of the processing.

[0035] As an example, and not a limitation, the drive unit 2 drives the second connecting rod 41 to rotate, moving the tool setter 43 to the front of the tool head 53. The electric slider 56 drives the moving seat 52 to move along the guide rail 51, while the electric slide rail 54 drives the chuck 55 to move laterally, thus moving the tool head 53 to the tool setter 43. The tool setting operation is performed through the cooperation of the moving seat 52 and the electric slide rail 54 and the tool setter 43. Before the tool setting operation, the drive unit 2 controls the first connecting rod 31 to rotate, moving the air nozzle 34 to the tool setter 43 to remove debris adhering to the tool setter 43, thereby improving the accuracy of the tool setting. When the tool setter 43 needs to be replaced, turn the knob 424 and move the upper clamp 42 upward along the limit plate 44, away from the lower clamp 42. Then remove the old tool setter 43, place the new tool setter 43 between the upper clamp 421 and the lower clamp 422, then lower the upper clamp 42 and turn the knob 424 to clamp the tool setter 43 firmly with the lower clamp 422 and the upper clamp 421.
