[0001] The present application relates to the technical field of tool-path lathe, in particular to a tool-path lathe with standby machining structure. BACKGROUND

[0002] The tool-path lathe is an automatic metal cutting machine tool, mainly used for machining shafts, sleeves and other rotary parts.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example:

[0033] Please see the appendix Figure 1 - Appendix Figure 9 This invention provides a sliding lathe with a backup machining structure, comprising:

[0034] Machine base 1, as the basic load-bearing structure of the entire sliding lathe, provides a stable mounting platform and support for various functional components. A protective shell 2 is installed on the upper surface of machine base 1. The protective shell 2 can effectively block metal chips splashed during processing, and also plays a role in sound insulation and dust prevention, ensuring a safe operating environment. An electric track 3 is installed on the upper surface of machine base 1. The electric track 3 adopts a CNC drive method, which can realize high-precision linear displacement adjustment and provide power for the position adjustment of subsequent components. The top of the output shaft of the electric track 3 is arranged from top to bottom with a cutting component 4 and a secondary spindle component 5. This vertical arrangement can make full use of space and avoid motion interference between different components during operation. The main spindle 7 is installed on the upper surface of the electric track 3 near the left end. The main spindle 7 is the core clamping and rotating component for workpiece processing, which can drive the workpiece to rotate at high speed to cooperate with the cutting operation. The secondary processing component 6 is located on the upper surface of machine base 1 near the front end of the main spindle 7. The secondary processing component 6 serves as a backup processing unit, specifically for processing the areas obscured by the workpiece, thus overcoming the processing limitations of traditional lathes.

[0035] The auxiliary machining component 6 includes a support frame 61, which is made of high-strength alloy material and has sufficient structural rigidity to withstand the cutting forces during machining. The support frame 61 is mounted on the upper surface of the machine base 1 and is fastened to the machine base 1 with bolts to ensure no loosening or displacement during operation. A slide rail 62 is fixedly connected to the upper surface of the support frame 61. The inner wall of the slide rail 62 is precision ground to reduce sliding friction resistance with subsequent components. A moving track 63 is slidably connected to the inner wall of the slide rail 62. The moving track 63 can slide smoothly along the extension direction of the slide rail 62 to realize the feed adjustment of the cutter head 66. A fixing frame 65 is installed on the side of the moving track 63 near the electric track 3. The structural design of the fixing frame 65 is adapted to the installation and fixing of various types of cutter heads, improving the versatility of the component. The cutter head 66 is mounted on the right surface of the fixing frame 65. The cutter head 66 can be selected from different types such as turning tools and milling cutters according to machining requirements to achieve diverse cutting functions.

[0036] A feed cylinder 64 is mounted on the upper surface of the support frame 61. The feed cylinder 64 is pneumatically driven, with fast response and high control precision, suitable for short-stroke feed actions. The output shaft of the feed cylinder 64 is fixedly connected to the lower surface of the moving track 63. The extension and retraction of the output shaft directly drives the moving track 63 to slide along the slide rail 62, resulting in high transmission efficiency. The front surface of the moving track 63 is provided with multiple sets of mounting slots 612. These multiple sets of mounting slots 612 are evenly distributed along the length of the moving track 63, providing flexible installation position selection for the brake block 67. The inner wall of one set of mounting slots 612 is fitted with the brake block 67, and the front surface of the support frame 61 is fitted with mounting blocks 69.

[0037] Mounting block 69 is L-shaped, and its L-shape can block brake block 67, thereby controlling the movement distance of moving track 63. A locking cylinder 610 is mounted on the lower surface of mounting block 69. Locking cylinder 610 shares a pneumatic control system with feed cylinder 64, enabling coordinated action. The output shaft of locking cylinder 610 passes through the upper surface of mounting block 69, and a locking block 611 is fixedly connected to the top of the output shaft. The shape of locking block 611 matches locking groove 68, ensuring fit and stability during locking. A locking groove 68 is provided on the lower surface of brake block 67, and the inner wall of locking groove 68 is chamfered to facilitate quick and accurate insertion of locking block 611.

[0038] The sub-shaft assembly 5 includes a mounting bracket 51, which is a frame structure with ample internal space for installing drive and transmission components. The mounting bracket 51 is mounted on the upper surface of the output shaft of the electric track 3, and its overall position moves with the movement of the electric track 3, allowing for precise docking with the main spindle 7 or the auxiliary machining assembly 6. A rotating shaft 57 is rotatably connected to the inner wall of the mounting bracket 51, and the rotating shaft 57 is connected to the mounting bracket 51 through bearings to ensure smooth rotation and low friction loss.

[0039] A pressing shaft 54 ​​is slidably connected to the inner wall of the rotating shaft 57. The pressing shaft 54 ​​can slide along the axial direction of the rotating shaft 57. The pressing action drives the clamping sleeve 55 to clamp the workpiece. The clamping sleeve 55 is fixedly connected to the inner wall of the rotating shaft 57. The clamping sleeve 55 is made of elastic material and can generate radial contraction under the pressing action to clamp the workpiece. A drive motor 58 is installed on the inner wall of the mounting frame 51. The drive motor 58 is a servo motor, which can realize stepless speed adjustment to adapt to different processing requirements. The drive motor 58 and the rotating shaft 57 are connected by synchronous belt drive. The synchronous belt drive has the characteristics of accurate transmission ratio and smooth operation, which can ensure the speed accuracy of the rotating shaft 57.

[0040] A clamping cylinder 52 is mounted on the front surface of the mounting bracket 51. The clamping cylinder 52 serves as the power source for the extrusion shaft 54, driving subsequent components through its extension and retraction. A swing rod 53 is hinged to the left end of the output shaft of the clamping cylinder 52. This hinge allows the swing rod 53 to rotate around the connection point, converting the linear motion of the cylinder into swing motion. The swing rod 53 is made of high-strength steel, capable of withstanding the driving force transmitted by the clamping cylinder 52 without deformation. The end of the swing rod 53 closest to the rotating shaft 57 rotates... A sliding sleeve 510 is movably connected. The sliding sleeve 510 can slide axially along the rotating shaft 57 with the movement of the swing rod 53, without affecting the rotation of the rotating shaft 57. A pressing sleeve 512 is rotatably connected to the inner wall of the sliding sleeve 510. A ball bearing is provided between the pressing sleeve 512 and the sliding sleeve 510 to reduce friction during relative rotation. The pressing sleeve 512 is slidably connected to the outer wall of the rotating shaft 57. The pressing sleeve 512 can slide along the rotating shaft 57 under the drive of the sliding sleeve 510, thereby pressing the transmission rod 56.

[0041] A fixed sleeve 511 is fixedly connected to the outer wall of the rotating shaft 57. The fixed sleeve 511 rotates synchronously with the rotating shaft 57, providing a base for the installation and limiting of the transmission rod 56. The transmission rod 56 is rotatably connected to the inner wall of the fixed sleeve 511. The transmission rod 56 can rotate under the action of the extrusion sleeve 512, thereby pushing the extrusion shaft 54 ​​to extrude the clamping sleeve 55 to clamp the workpiece. The end of the extrusion sleeve 512 near the transmission rod 56 is set in a frustum shape. The frustum shape structure can efficiently convert the axial force of the extrusion sleeve 512 into the radial force of the transmission rod 56.

[0042] The cutting assembly 4 includes a cutting frame 41, which is an integrally cast structure with high structural strength, capable of withstanding vibration and impact during the cutting process. The cutting frame 41 is mounted on the top of the output shaft of the electric track 3, and its highest position avoids motion interference with the sub-shaft assembly 5 and other components. A cutting head 43 is rotatably connected to the upper surface of the cutting assembly 4 near the main shaft 7. The cutting head 43 can be replaced with different cutting tools such as grinding wheels and saw blades according to processing requirements.

[0043] A cutting motor 42 is mounted on the upper surface of the cutting frame 41, away from the spindle 7. The cutting motor 42 is designed with high power to provide sufficient cutting power to handle workpieces of different materials. The cutting head 43 is connected to the cutting motor 42 via a synchronous belt drive.

[0044] An air pipe 59 is mounted on the right surface of the rotating shaft 57. The air pipe 59 is connected to an external air source device to provide power for the separation of the workpiece from the clamp 55. The air pipe 59 is in communication with the inner wall of the clamp 55, and air pressure can enter the interior of the clamp 55 through the air pipe 59 to push the workpiece apart.

[0045] Working principle: Before processing, the bar stock to be processed is loaded into the main spindle 7 and clamped and fixed by it. The main spindle 7 drives the workpiece to rotate, while the electric track 3 drives the cutting assembly 4 to move. The cutting motor 42 drives the cutting head 43 to rotate at high speed through the synchronous belt, performing preliminary cutting processing on the exposed part of the workpiece. After the exposed side of the workpiece is processed, the electric track 3 drives the sub-shaft assembly 5 to move to the main spindle 7. The output shaft of the clamping cylinder 52 extends and retracts, pushing the swing rod 53 to swing. The swing rod 53 drives the extrusion sleeve 512 to slide along the rotating shaft 57 through the sliding sleeve 510. The frustum-shaped extrusion sleeve 512 extrudes the transmission rod 56 on the fixed sleeve 511. The transmission rod 56 pushes the extrusion shaft 54 ​​to extrude the clamping sleeve 55, causing the clamping sleeve 55 to contract radially. The workpiece is clamped; then the main spindle 7 releases the workpiece, and the electric track 3 drives the sub-spindle assembly 5 to move to the position aligned with the sub-machining assembly 6. The drive motor 58 drives the rotating shaft 57 and the workpiece to rotate via the synchronous belt. At this time, the feed cylinder 64 pushes the moving track 63 to slide along the slide rail 62, causing the cutter head 66 on the fixed frame 65 to move closer to the workpiece. The brake block 67 and the mounting block 69 cooperate to limit the movement range of the moving track 63. The locking cylinder 610 drives the locking block 611 to insert into the locking groove 68 to lock the brake block 67. The cutter head 66 processes the side of the workpiece that is blocked by the main spindle 7. After the processing is completed, air pressure is introduced into the air pipe 59. The air pressure enters the inner wall of the clamp 55 to push it to reset and release the workpiece, completing the entire processing process.
