Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of mechanical parts processing equipment, and more specifically, to a CNC machine tool for parts production. Background Technology

[0002] In the field of mechanical parts manufacturing, shafts (such as motor shafts and drive shafts) are core transmission components of various equipment, and their surface machining accuracy (such as roughness and cylindricity) directly determines the transmission efficiency and operational stability of the equipment. CNC machine tools, with their advantages of high precision and automation, have become the main equipment for milling, grinding, and turning shafts. As the manufacturing industry demands higher precision from parts, the ease of installation and stability of shaft surface machining are becoming increasingly critical. However, traditional CNC machine tools used for parts production suffer from a significant drawback in their cumbersome installation process when machining shaft surfaces, severely restricting production efficiency and machining accuracy.

[0003] The installation of shaft parts on traditional CNC machine tools requires multiple manual adjustments to align the parts with the machining reference: first, the parts are initially fixed using a three-jaw chuck, and then the coaxiality of the parts is repeatedly calibrated using tools such as dial indicators and micrometers. The calibration process requires stopping the machine. For shaft parts with a large length-to-diameter ratio or heavy weight, an additional tailstock center is required for auxiliary fixation, further increasing the installation steps and time costs.

[0004] Therefore, developing CNC machining tools for component production that can simplify the installation process of shaft parts and improve installation stability has become an urgent need for the industry to improve quality and efficiency. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a CNC machining tool for parts production, which solves the technical problem of cumbersome installation process when machining shaft parts on the surface of traditional CNC machining tools used for parts production.

A drive frame is connected to the side cavity via a horizontal linear drive. The drive frame is located on both sides of the machine tool body. A pair of support rollers are rotatably connected to the surface of the machine tool body. A pair of pressure rollers are rotatably connected between the drive frames.

[0007] As a further technical solution, the support roller and the pressing roller are positioned at the same height, and a transmission cavity is provided on the surface of the machine tool body. Moving columns are horizontally slidably connected to both sides of the transmission cavity.

[0008] As a further technical solution, each of the transmission cavities is horizontally rotatably connected with a drive screw, one end of which is connected to the moving column via a threaded connection, and a drive motor is installed inside the machine tool body.

[0010] As a further technical solution, the output end of the telescopic cylinder is provided with a support base, and each of the side surfaces of the support base is rotatably connected to a drive base, one of which is driven to rotate by electricity.

[0023] like Figures 1-4 As shown, it illustrates a CNC machining tool for parts production according to an embodiment of the present disclosure, comprising: The machine tool body 1 and the transverse cavity 2 are horizontally formed at the lower end of the surface of the machine tool body 1; Positioning and mounting component 3 is disposed on the machine tool body 1; Processing component 4 is disposed in the transverse cavity 2; The positioning and mounting assembly 3 includes a pair of side cavities 3-1, which are located on both sides of the machine tool body 1. A drive frame 3-2 is horizontally linearly driven into each side cavity 3-1. The drive frame 3-2 is located on both sides of the machine tool body 1. A pair of support rollers 3-3 are horizontally rotatably connected to the surface of the machine tool body 1. A pair of pressure rollers 3-4 are rotatably connected between the drive frames 3-2. The support rollers 3-3 and the pressure rollers 3-4 are positioned at corresponding heights. A transmission cavity 3-5 is formed on the surface of the machine tool body 1. Moving columns 3-6 are horizontally slidably mounted on both sides of the transmission cavity 3-5. -5 are all horizontally rotatably connected to drive screws 3-7. One end of the drive screw 3-7 is connected to the moving column 3-6 by a threaded connection. A drive motor 3-8 is installed in the machine tool body 1. The output end of the drive motor 3-8 and one end of the drive screw 3-7 are both provided with transmission gears 3-9. The transmission gears 3-9 are bevel gears. One end of the moving column 3-6 is horizontally connected to a telescopic cylinder 3-10. The output end of the telescopic cylinder 3-10 is provided with a support seat 3-11. A drive seat 3-12 is rotatably connected to the side surface of the support seat 3-11. One of the drive seats 3-12 is driven to rotate by electricity.

[0024] In some examples, in order to achieve quick clamping, stable support and rotation drive of shaft components, adapt to the surface machining requirements such as shaft outer circle machining and milling, and ensure that the shaft components do not shift and rotate smoothly during the machining process, a positioning and mounting component 3 is designed. The side cavities 3-1 on both sides of the machine tool body 1 of this component provide space for the movement of the active frame 3-2.

[0025] The output end of the horizontal linear drive component (such as a cylinder) in the side cavity 3-1 is fixedly connected to the active frame 3-2, which can drive the active frame 3-2 to move closer to or away from the center of the machine tool body 1 along the side cavity 3-1. The drive components of the active frames 3-2 on both sides are synchronously controlled to ensure that the clamping force of the clamping roller 3-4 on the shaft is balanced.

[0026] A pair of support rollers 3-3 on the surface of the machine tool body 1 are horizontally rotatably connected by a bearing seat and distributed along the length of the machine tool to provide one-sided support for the shaft. They can reduce the rotational resistance of the shaft as it rotates. A pair of clamping rollers 3-4 rotatably connected between the drive frame 3-2 correspond one-to-one with the height position of the support rollers 3-3 and are located on the horizontal side of the support rollers 3-3. When the drive frame 3-2 moves towards the center, the clamping rollers 3-4 can fit against the other side of the shaft and form a left-right clamping structure with the support rollers 3-3 to prevent axial movement or radial displacement of the shaft during processing.

[0027] The transmission cavity 3-5 on the surface of the machine tool body 1 is opened along the length direction. The moving columns 3-6 on both sides of the cavity are horizontally slidably fitted onto the inner wall of the transmission cavity 3-5 through the sliding sleeve, ensuring that the moving columns 3-6 move smoothly only in the horizontal direction. The drive screw 3-7 is horizontally rotatably connected in the transmission cavity 3-5. One end is connected to the side wall of the transmission cavity 3-5 through the bearing, and the other end passes through the moving column 3-6 through the threaded engagement, forming a screw transmission structure.

[0028] The output end of the drive motor 3-8 inside the machine tool body 1 meshes with the transmission gear 3-9 (both bevel gears) at one end of the drive screw 3-7, which can convert the horizontal rotational power of the motor into the vertical rotational power of the drive screw 3-7. The telescopic cylinder 3-10, which is fixed horizontally at one end of the moving column 3-6, has its output end facing the center of the machine tool and is fixedly connected to the support base 3-11. It can drive the support base 3-11 to extend and retract in the horizontal direction to meet the clamping requirements of shafts of different lengths. The drive base 3-12 is rotatably connected to the side surface of the support base 3-11 through a bearing. The center of its end face corresponds to the shaft center. One of the drive bases 3-12 is fixedly connected to the output end of an electric drive (such as a servo motor) and can drive the drive base 3-12 to rotate.

[0029] During operation, the shaft is placed on the support roller 3-3. The horizontal linear drive unit drives the active frame 3-2 to move, causing the clamping roller 3-4 to clamp the shaft. The drive motor 3-8 starts and drives the drive screw 3-7 to rotate via the bevel gear. The moving column 3-6 drives the support seat 3-11 to move closer to both ends of the shaft. The telescopic cylinder 3-10 pushes the drive seat 3-12 to press against both ends of the shaft. During machining, the electrically driven drive seat 3-12 drives the shaft to rotate, cooperating with the machining component 4 to complete the surface machining. This component, through the coordination of multiple parts, achieves rapid clamping and stable rotation of the shaft, ensuring machining accuracy.

[0030] like Figures 1-4 As shown in the figure, the processing component 4 in this embodiment includes a base 4-1, which is connected to the transverse cavity 2 by a horizontal linear drive. An adjusting cylinder 4-2 is horizontally connected to the bottom of the base 4-1, and a connecting seat 4-3 is provided at the output end of the adjusting cylinder 4-2. A tool holder 4-4 is connected to the top of the connecting seat 4-3 by a vertical linear drive.

[0031] In some examples, in order to achieve machining from the bottom of the shaft upwards, avoid the waste generated during machining from wrapping around the tool, and adapt to the machining requirements of different positions of the shaft, thereby improving machining efficiency and tool life, a machining component 4 is designed. The base 4-1 in the transverse cavity 2 of this component is connected by a horizontal linear drive (such as a ball screw mechanism). The drive is fixed along the length of the transverse cavity 2 and can drive the base 4-1 to move along the length of the transverse cavity 2, adjust the axial relative position of the tool and the shaft, and cover the machining area of ​​the entire length of the shaft.

[0032] The base 4-1 has a horizontally fixed adjusting cylinder 4-2 at its bottom. The output end extends along the width of the transverse cavity 2 and is fixedly connected to the connecting seat 4-3. This cylinder can drive the connecting seat 4-3 to move along the width direction, further fine-tuning the radial position of the tool and ensuring that the tool is accurately aligned with the machining area.

[0033] The vertical linear drive component (such as a lead screw) on the top of the connecting seat 4-3 is set vertically upward, and its output end is fixedly connected to the tool holder 4-4. It can drive the tool holder 4-4 to rise and fall in the vertical direction, realize the contact or separation between the tool and the surface of the shaft, and control the machining depth. The tool holder 4-4 is fixed to the output end of the vertical linear drive component by bolts. The tool mounting groove on its side surface is compatible with the machining tool, and different types of tools (such as milling cutters and turning tools) can be quickly changed to meet the machining requirements of different surfaces of the shaft.

[0034] This component adopts a bottom-up machining structure. The tool rises from below the shaft through a vertical linear drive to contact the shaft surface. The machining chips generated fall naturally downwards under the action of gravity and will not get tangled on the rotating shaft or tool, thus avoiding the chips from affecting the machining accuracy or causing tool wear.

[0035] During operation, according to the processing position requirements, the horizontal linear drive unit drives the base 4-1 to move along the length direction of the transverse cavity 2, and the adjusting cylinder 4-2 drives the connecting seat 4-3 to make a fine adjustment along the width direction so that the tool holder 4-4 is aligned with the target processing area; the vertical linear drive unit drives the tool holder 4-4 to rise, causing the tool to contact the surface of the shaft to complete the processing.

[0036] During the machining process, the waste chips fall naturally without the need for additional cleaning. After machining is completed, the vertical linear drive component drives the tool holder 4-4 to descend and reset. Then, the positions of the base 4-1 and the connecting seat 4-3 are adjusted to proceed to the next machining step. The multi-directional adjustment structure ensures accurate tool positioning, and the bottom machining layout avoids waste chip entanglement. All components work together to achieve efficient and accurate machining of shafts and extend tool life.

[0037] For example, such as Figure 1 As shown, a collection groove 5 is provided at the bottom of the machine tool body 1, and the bottom of the collection groove 5 is an inclined structural surface.

[0038] In some examples, the collection groove 5 at the bottom of the machine tool body 1 can collect the waste chips that fall naturally during the processing, preventing the waste chips from scattering inside the machine tool or on the ground and reducing the amount of cleaning work.

[0039] The inclined surface at the bottom of the collection tank 5 allows waste chips to be guided by gravity to a lower position, facilitating quick cleaning by operators. After falling into the collection tank 5, the waste chips will automatically slide along the inclined surface to the bottom of the tank. At the same time, the inclined surface also reduces the residue of waste chips at the bottom of the tank, keeping the inside of the collection tank 5 clean even after long-term use, ensuring the cleanliness of the machine tool bottom area and the normal operating environment of the equipment.

[0040] For example, such as Figure 1 As shown, the surface of the drive seat 3-12 is a frosted, non-slip structure.

[0041] In some examples, the frosted anti-slip surface of the drive seat 3-12 can significantly enhance the friction between the drive seat 3-12 and the end face of the shaft. When the drive seat 3-12 is pressed against both ends of the shaft, the frosted surface can fit tightly against the end face of the shaft, preventing the shaft from slipping during rotational machining. This ensures that the rotational power of the drive seat 3-12 can be stably transmitted to the shaft, allowing the shaft to maintain uniform and smooth rotation, and avoiding problems such as uneven texture and dimensional deviation on the machined surface caused by slippage.

[0042] In addition, the frosted structure can adapt to slight unevenness on the end face of the shaft, and compensate for the gap between the end faces by increasing the contact friction, thereby further improving the stability of the shaft rotation and ensuring machining accuracy.

[0043] In practical use: Place the shaft-type component on one side of the support roller 3-3 of the machine tool body 1. Activate the horizontal linear drive in the side cavity 3-1, driving the active frame 3-2 to move towards the center, so that the clamping roller 3-4 fits against both sides of the component, working in conjunction with the support roller 3-3 to clamp the component. The drive motor 3-8 drives the drive screw 3-7 in the transmission cavity 3-5 to rotate via bevel gears. The moving column 3-6 slides along the transmission cavity 3-5, and the telescopic cylinder 3-10 pushes the support seat 3-11 closer to both ends of the component, with the drive seat 3-12 pressing against the component. Electric drive rotates one of the drive seats 3-12, causing the component to rotate synchronously. Activate the machining assembly 4. The horizontal linear drive moves the base 4-1 along the transverse cavity 2. The adjusting cylinder 4-2 fine-tunes the position of the connecting seat 4-3. The vertical linear drive pushes the tool holder 4-4 upward, and the tool contacts the surface of the component to complete the machining. The generated waste chips fall into the bottom collection groove 5. After machining, all components are reset, and the component can be removed. The entire process achieves rapid clamping and precise machining of shaft-type parts.
