Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, specifically to a servo tool post structure for a CNC lathe. Background Technology

[0002] A CNC tool turret is an auxiliary device on a CNC lathe, primarily used to hold the cutting tools. It allows the CNC lathe to complete multiple or even all machining operations in a single workpiece clamping, thereby shortening auxiliary machining time, reducing errors caused by multiple workpiece setups, and improving the machine tool's machining efficiency and accuracy. CNC tool turrets are typically equipped with a moving mechanism to adjust their position.

[0003] For example, announcement number CN214108806U, entitled "A Multi-Set Rolling Linear Guide CNC Vertical Lathe Tool Post," describes a CNC vertical lathe with multiple sets of rolling linear guides installed parallel to the side wall of the crossbeam. Each set of rolling linear guides has several heavy-duty roller sliders. The CNC vertical lathe tool post is mounted on these heavy-duty roller sliders. Each heavy-duty roller slider has a guide slide and a scraper on both sides. All contact surfaces of the heavy-duty roller sliders are scraped, with a scraped contact area requirement of ≥65%. The track between the uppermost and lowermost rolling linear guides serves as an auxiliary force-bearing track. Adjusting shims are sandwiched between the heavy-duty roller sliders on the auxiliary force-bearing track and the CNC vertical lathe tool post. These shims are appropriately thickened based on calculated load-bearing and stress-deformation results. This preloads the rolling linear guides under load, improving the cutting rigidity of the tool post and increasing the service life of the rolling linear guides.

[0004] Although the existing CNC tool post can be adjusted in position by a moving device, the tool post displacement device is exposed to the outside, and the waste generated during the machining process can easily enter the interior, which can affect the normal movement of the tool post. Therefore, it does not meet the current requirements. To address this, a CNC lathe servo tool post structure is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a servo tool post structure for CNC lathes, in order to solve the problem mentioned in the background art that although the existing CNC tool post can be adjusted by a moving device, the tool post displacement device is exposed to the outside, and the waste generated during the machining process can easily enter the interior, which can easily affect the normal movement of the tool post.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a CNC lathe servo tool post structure, comprising: a servo tool post, a base, a first displacement component, and a second displacement component. The rear end of the servo tool post is equipped with a first displacement component for driving its lateral displacement, and the rear end of the first displacement component is equipped with a second displacement component for driving its vertical displacement. The bottom of the second displacement component is equipped with a base, and both the first displacement component and the second displacement component are provided with shielding components for protecting internal parts.

[0007] Preferably, the first displacement component includes an assembly frame, a first lead screw is mounted on the front end of the assembly frame, a first slide is mounted on the outer wall of the first lead screw, the servo tool holder is mounted on the front end face of the first slide by bolts, and a first motor is mounted on one end of the first lead screw.

[0008] Preferably, the shielding assembly includes a first folding shield and a second folding shield. The two ends of the first folding shield are respectively connected to the tail end of the first slide and the assembly frame, and the second folding shield is disposed outside the front end of the first motor.

[0009] Preferably, the shielding assembly further includes a first baffle bolted to the bottom of the mounting frame, a second baffle mounted below the first baffle, and a third baffle mounted below the second baffle. The dimensions of the first baffle, the second baffle, and the third baffle decrease sequentially, and the first baffle, the second baffle, and the third baffle are vertically slidably connected to each other.

[0010] Preferably, both the upper and lower ends of the first lead screw are provided with slide rails, and multiple sets of sliders are installed on the outer wall of the slide rails. The rear end face of the first slide block is provided with an assembly groove that combines with the sliders.

[0011] Preferably, the second displacement component includes an assembly column, a second lead screw is installed at the front end of the assembly column, a second motor is installed at the upper end of the second lead screw, a second slide is installed on the outer wall of the second lead screw, and the second slide is connected to the assembly frame by bolts.

[0012] Preferably, the front end of the assembly column is provided with symmetrical limiting grooves, and a slide is installed in the limiting groove. The rear end face of the assembly frame is provided with multiple sets of combination blocks, and the rear end face of the combination blocks is provided with a groove that slides in combination with the slide.

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

[0014] (1) In this utility model, the first slide is moved laterally by the first motor and the first lead screw to adjust the position of the servo tool post. At this time, the first displacement component is protected by the first folding cover and the second folding cover. When it moves away from the first motor, the first folding cover is squeezed and folded as the first slide moves away, while the second folding cover at the other end is stretched and expanded. When it moves in the opposite direction, the first folding cover is stretched and expanded, and the second folding cover is squeezed and folded. This allows the servo tool post to protect the displacement component in a targeted manner while having the displacement function, effectively reducing the adverse effects of impurities on the displacement component.

[0015] (2) In this utility model, the second motor and the second lead screw are used to drive the second slide and the assembly frame to perform vertical displacement operation. When no displacement is performed, the internal parts are protected by the externally set first baffle, second baffle and third baffle. When the displacement is downward, the assembly frame drives the first baffle to move downward together, so that the first baffle slides down on the second baffle, so as not to affect the normal displacement process. When the displacement is upward, the assembly frame drives the first baffle to slide up on the second baffle, so that it returns to the initial position. The above structure can effectively protect the vertical displacement parts, making the displacement parts at the servo tool holder safer to use. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1 , Figure 2 This utility model provides an embodiment of a CNC lathe servo tool post structure, comprising: a servo tool post 1, a base 2, a first displacement component 3, and a second displacement component 4. The rear end of the servo tool post 1 is equipped with the first displacement component 3 for lateral displacement, and the rear end of the first displacement component 3 is equipped with the second displacement component 4 for vertical displacement. The base 2 is installed at the bottom of the second displacement component 4. Both the first displacement component 3 and the second displacement component 4 are externally provided with shielding components for protecting internal parts. The first displacement component 3 includes an assembly frame 301, the front end of which is equipped with a first lead screw 307. A first slide block 303 is installed on the outer wall of the first lead screw 307. The servo tool post 1 is bolted to the first slide block 3. On the front end face of 03, a first motor 302 is installed at one end of the first lead screw 307. The shielding assembly includes a first folding shield 308 and a second folding shield 309. The two ends of the first folding shield 308 are respectively connected to the tail end of the first slide block 303 and the assembly frame 301. The second folding shield 309 is located outside the front end of the first motor 302. Slide rails 305 are provided at both the upper and lower ends of the first lead screw 307. Multiple sets of sliders 306 are installed on the outer wall of the slide rail 305. The rear end face of the first slide block 303 is provided with an assembly groove 304 that combines with the sliders 306. When the lead screw drives the first slide block 303 to move, the rear end of the first slide block 303 also slides on the slide rail 305 through multiple sliders 306, making its movement smoother and more stable.

[0024] The first motor 302 and the first lead screw 307 drive the first slide block 303 to move laterally, which is used to adjust the position of the servo tool holder 1. At this time, the first folding cover 308 and the second folding cover 309 protect the first displacement component 3. When it moves away from the first motor 302, the first folding cover 308 is squeezed and folded as the first slide block 303 moves, while the second folding cover 309 at the other end is stretched and expanded. When it moves in the opposite direction, the first folding cover 308 is stretched and expanded, and the second folding cover 309 is squeezed and folded. This allows the servo tool holder 1 to not only have the displacement function, but also to specifically protect the displacement component, effectively reducing the adverse effects of impurities on the displacement component.

[0025] Please see Figure 3 , Figure 4 , Figure 5 The second displacement component 4 includes an assembly column 401, a second lead screw 404 mounted at the front end of the assembly column 401, a second motor 403 mounted at the upper end of the second lead screw 404, a second slide block 405 mounted on the outer wall of the second lead screw 404, and the second slide block 405 connected to the assembly frame 301 by bolts. The front end of the assembly column 401 has symmetrically formed limit grooves 402, in which a slide block 406 is installed. Multiple sets of assembly blocks 407 are mounted on the rear end face of the assembly frame 301. The rear end face of the assembly 407 has a slot for sliding in combination with the slide 406. The shielding assembly also includes a first baffle 408 that is bolted to the bottom of the assembly frame 301. A second baffle 409 is installed below the first baffle 408, and a third baffle 410 is installed below the second baffle 409. The dimensions of the first baffle 408, the second baffle 409, and the third baffle 410 decrease sequentially, and the first baffle 408, the second baffle 409, and the third baffle 410 are vertically slidably connected to each other.

[0026] The second motor 403 and the second lead screw 404 are used to drive the second slide 405 and the assembly frame 301 to perform vertical displacement operations, so that the assembly block 407 at the rear end of the assembly frame 301 slides on the slide 406. When no displacement is performed, the internal parts are protected by the externally set first baffle 408, second baffle 409 and third baffle 410. When moving downward, the assembly frame 301 drives the first baffle 408 to move downward together, so that the first baffle 408 slides downward on the second baffle 409, so as not to affect the normal displacement process. When moving upward, the assembly frame 301 drives the first baffle 408 to slide upward on the second baffle 409, so as to reset it to the initial position. The above structure can effectively protect the vertical displacement components, making the displacement components at the servo tool holder 1 safer to use.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
