Description

Technical Field

[0001] This invention belongs to the field of machine tool equipment technology, specifically a CNC machine tool control box. Background Technology

[0002] CNC machine tool control systems are a rapidly developing new branch of technology in recent years. Currently, in the process of machining parts, CNC machine tool control boxes can only achieve automated machining programming. However, the strong vibration of the material itself during machining can easily cause dimensional defects, leading to significant problems in later processing and material waste. At the same time, the high frequency of use of the machine tool chuck causes severe wear, reducing the clamping tightness of the parts and affecting the machining quality, thus increasing production costs to some extent.

[0003] Therefore, those skilled in the art have provided a CNC machine tool control box to solve the problems mentioned in the background art. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a CNC machine tool control box, comprising: a machine tool body, a spindle box mounted on the upper end face of the machine tool body for supporting the spindle and driving the spindle to rotate, a machine tool control system located on one side of the spindle box on the machine tool body for controlling the machine tool's movements and machining process, a chuck mounted on the spindle box, and an autonomous vibration damping component disposed inside the spindle box, the autonomous vibration damping component being controlled by the machine tool control system, and a machining anti-sway device also disposed on one side of the spindle box on the machine tool body.

[0005] Furthermore, as a preferred embodiment, the autonomous vibration damping component includes: a rotating shaft frame, rotatably disposed within the spindle box, one end of the rotating shaft frame being fixed to the chuck, multiple inner clamping members distributed circumferentially within the chuck, each inner clamping member being slidably connected to the chuck, and each inner clamping member having axially slidably disposed clamping teeth for positioning and clamping the workpiece; a dynamic vibration damping device slidably disposed within the rotating shaft frame, the dynamic vibration damping device being connected to each of the clamping teeth via multiple connecting supports; an airflow annular chamber fixed within the rotating shaft frame, a push plug slidably disposed within the airflow annular chamber, one end of the push plug being connected to the dynamic vibration damping device; and a pneumatic seat disposed on one side of the rotating shaft frame, the pneumatic seat being connected to the airflow annular chamber.

[0008] Furthermore, as a preferred embodiment, a contact shaft is slidably disposed inside the pressure member, and an inner spring is connected between the contact shaft and the pressure member. Each pressure member is also connected to an air inlet pipe for air injection and pressurization.

[0012] 1. In this invention, the spindle box is mainly equipped with an autonomous vibration damping component that can dynamically dampen the vibration of one end of the material being processed, thereby reducing the shaking amplitude of the material during processing. In particular, the clamping teeth are also provided, which can perform processing and clamping through the axial displacement of the dynamic vibration damping device, avoiding chuck wear, extending its service life, and thus ensuring processing accuracy.

Detailed Implementation

[0021] Please see Figure 1 In this embodiment of the invention, a CNC machine tool control box includes: a machine tool body 1, a spindle box 2 mounted on the upper surface of the machine tool body 1 for supporting the spindle and driving the spindle to rotate, a machine tool control system 11 located on one side of the spindle box 2 on the machine tool body 1 for controlling the machine tool's movements and machining process, a chuck 12 mounted on the spindle box 2, and an autonomous vibration damping component 4 disposed inside the spindle box 2, the autonomous vibration damping component 4 being controlled by the machine tool control system, and a machining anti-sway device 3 also disposed on one side of the spindle box 2 on the machine tool body 1. That is, the machine tool control system can drive the autonomous vibration damping component to perform dynamic vibration damping on one end of the machining material, thereby reducing the swaying amplitude of the machining material and improving machining accuracy.

[0022] In this embodiment, the autonomous vibration damping component 4 includes: a rotating shaft tube frame 41, which is rotatably disposed in the spindle box 2. One end of the rotating shaft tube frame 41 is fixed to the chuck 12. Multiple inner clamping members 42 are distributed circumferentially inside the chuck 12. The inner clamping members 42 are all slidably connected to the chuck 12. Each inner clamping member 42 is axially slidably provided with clamping teeth 44 for positioning and clamping the workpiece. A dynamic vibration damping device 5 is slidably disposed inside the rotating shaft tube frame 41. The dynamic vibration damping device 5 is connected to each of the clamping teeth 44 through multiple connecting supports 43. An airflow annular chamber 45 is also fixed inside the rotating shaft tube frame 41. A push plug 46 is slidably disposed inside the airflow annular chamber 45. One end of the push plug 46 is connected to the dynamic vibration damping device 5. A pneumatic seat 47 is also disposed on one side of the rotating shaft tube frame 41. The pneumatic seat 47 is connected to the airflow annular chamber 45.

[0023] In a preferred embodiment, the contact surface between the inner clamp 42 and the clamping teeth 44 is set as an inclined structure. The dynamic vibration damping device can slide synchronously mainly through the axial displacement of the pusher. At this time, each clamping tooth can form a clamping and positioning of the processing material by the contact surface of the inner clamp, which fundamentally avoids clamping wear, improves chuck life, and ensures processing accuracy.

[0024] In this embodiment, the dynamic vibration damping device 5 includes: a fixed shaft seat 51, which is slidably disposed within the rotating shaft tube frame 41. Multiple pressing members 52 are circumferentially disposed on the fixed shaft seat 51. The pressing members 52 are slidably disposed on the fixed shaft seat 51, and an adjusting disc 54 is rotatably disposed on the fixed shaft seat 51. The adjusting disc 54 has multiple oblique holes. A shaft body 53 is vertically fixed to the pressing member 52, and the shaft body 53 is slidably disposed within the oblique holes. A plastic ring 55 is also fitted inside the fixed shaft seat 51. Especially after the processed material is clamped, the dynamic vibration damping device can clamp and fix the main body of the processed material through the pressing members, thereby reducing the shaking of the main body.

[0025] In this embodiment, a contact shaft 56 is slidably disposed inside the pressure member 52, and an inner spring 57 is connected between the contact shaft 56 and the pressure member 52. Each pressure member 52 is connected to an air inlet pipe for air injection and pressurization. The contact shafts 56 in the opposing pressure members 52 slide in opposite directions, causing each contact shaft 56 to push one end of the workpiece to vibrate at a low frequency. In particular, the autonomous displacement sliding of the contact shafts in each pressure member causes the non-processed end of the workpiece to vibrate at a low frequency during rotation, thereby forming a resistance effect against the vibration of the processing end and improving the processing accuracy.

[0026] In this embodiment, the machining anti-sway device 3 includes: a guide rod 31, which is horizontally mounted on the machine tool body 1. A sliding frame 33 is slidably mounted on the guide rod 31. A transmission screw 32 is parallelly mounted on the machine tool body 1 between the guide rods 31. The sliding frame 33 is slidably sleeved on the transmission screw 32 through threaded engagement. A collar 34 is fixed on one side of the sliding frame 33.

[0027] In a preferred embodiment, the collar 34 and the spindle box 2 are concentrically arranged, and the collar 34 is provided with an elastic compression sleeve for movably fitting onto the workpiece. In particular, the elastic compression sleeve can be adjusted autonomously according to the outer diameter of the workpiece, so that it can slide axially along the workpiece during processing and form a processing limit on its end.

[0028] Specifically, the material to be processed can slide onto the chuck, where it is clamped and fixed by the cleaver teeth. At the same time, the self-vibration damping component can form a secondary clamping effect on the non-processed end of the material through the contact shaft. When the distance between the processing end and the chuck is greater than 15cm, the machine tool control system can generate low-frequency shaking during the rotation of the material through the self-vibration damping component, thereby creating a resistance effect against the vibration of the processing end and improving the processing accuracy. When the distance between the processing end and the chuck is less than or equal to 15cm, the self-vibration damping component only needs to clamp and fix the non-processed end.

[0029] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
