Description

Technical Field

[0001] This invention relates to the field of sliding head lathe technology, specifically to a highly stable sliding head lathe. Background Technology

[0002] A sliding lathe is a common type of machining lathe. It can drive the workpiece to rotate through the spindle and use the cutting tools mounted on the machine to cut the rotating workpiece, thus realizing the machining of the workpiece. The sliding lathes used in the present technology are generally CNC lathes, which can realize automatic machining using CNC technology.

[0003] In the prior art, sliding head lathes are generally used to process bar stock. Since sliding head lathes can perform continuous machining, the entire bar stock is inserted at once during machining, which can reduce the time required for changing materials and improve machining efficiency. However, during machining, sliding head lathes only rely on the spindle to fix the part to be machined, and do not have the ability to control the left end of the bar stock to be machined. Some bars have poor rigidity, and when the size is too long, the left end will bend under the action of gravity. As a result, when the entire bar stock rotates with the spindle, the entire bar stock will generate large vibrations, which will also drive the spindle to vibrate, thus affecting the machining accuracy of the entire device. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a highly stable sliding lathe that solves the problem that "existing sliding lathes do not machine the workpiece's work-to-be-machined parts, which vibrate during rotation, leading to a reduction in the overall machining accuracy of the device."

[0005] To achieve the above objectives, the present invention provides the following technical solution: a highly stable sliding lathe, comprising;

[0006] The machine tool has a protective cover installed on its upper surface. From left to right, a rear support assembly and a spindle assembly are installed on the upper surface of the machine tool. A side machining assembly is provided on the upper surface of the machine tool near the spindle assembly.

[0007] The rear support assembly includes a support platform, which is mounted on the upper surface of the machine base. A support seat is mounted on the upper surface of the support platform, and a guide sleeve is rotatably connected to the inner wall of the support seat.

[0008] The spindle assembly includes a support frame, which is fixedly connected to the upper surface of the machine tool, and a pneumatic clamping shaft is rotatably connected to the inner wall of the support frame.

[0009] Preferably, a protective sleeve is installed at the left end of the support base, a guide seat is installed on the inner wall of the protective sleeve, and a clamping block is slidably connected to the inner wall of the guide seat.

[0010] Preferably, a pressing block is slidably connected through the right surface of the guide seat, and the left end of the pressing block is set in an inclined shape.

[0011] Preferably, the rear support assembly further includes a clamping cylinder, which is mounted on the upper surface of the support base. A transmission rod is rotatably connected to the outer wall of the output shaft of the clamping cylinder. The transmission rod is rotatably connected to the left end of the support base. The rotating sleeve is rotatably connected to the inner wall of the transmission rod. The clamping cylinder and the pneumatic clamping shaft are driven by the same air source.

[0012] Preferably, a slider is fixedly connected to the outer wall of the clamping block, and the slider is elastically connected to the protective sleeve by a return spring.

[0013] Preferably, the spindle assembly further includes a rotary motor, which is mounted on the upper surface of the machine tool and is connected to the pneumatic clamping shaft via a synchronous belt drive.

[0014] Preferably, a brake disc is fixedly connected to the outer wall of the pneumatic clamping shaft, and a brake block adapted to the brake disc is fixedly connected to the outer wall of the support frame.

[0015] Preferably, the lateral machining assembly includes a machining cylinder, a mounting bracket is fixedly connected to the lower surface of the machining cylinder, the mounting bracket is fixedly connected to the upper surface of the machine tool, a sliding plate is slidably connected to the right end of the mounting bracket, and the output shaft of the machining cylinder is fixedly connected to the upper surface of the sliding plate.

[0016] Preferably, a connecting plate is installed on the front surface of the skateboard, a support sleeve is fixedly connected to the front surface of the connecting plate, and a drill bit is rotatably connected to the inner wall of the support sleeve.

[0017] Preferably, the lateral machining assembly further includes a drive motor, the drive motor and the support sleeve are connected by a gearbox, a stabilizing seat is fixedly connected to the lower surface of the support sleeve, and the drill bit is rotatably connected to the inner wall of the stabilizing seat.

[0018] This invention provides a highly stable feed lathe. It has the following advantages:

[0019] 1. By setting a rear support component, the present invention can support the unprocessed part of the bar stock. Before processing, the transmission rod can be driven to swing by the clamping cylinder. The transmission rod can push the transmission sleeve to squeeze the extrusion block, which in turn can drive the extrusion block to squeeze the clamping block. The clamping block will move towards the center position to clamp the workpiece under the extrusion, thus fixing the free end of the workpiece, thereby reducing the vibration during processing and improving the processing accuracy of the overall device.

[0020] 2. By setting a brake disc, the present invention can energize the brake block when the pneumatic clamping shaft is not required to rotate, thereby activating the brake block to fix the brake disc, thus locking the pneumatic clamping shaft. This can prevent it from shaking during drilling, further improve the stability of the machining process, and ensure machining accuracy.

[0021] 3. By setting a sliding plate, the movement of the connecting plate can be guided, thus ensuring the stability of the drill bit's vertical movement. At the same time, the stabilizing seat can guide the drill bit's outer wall near the lower end, thus preventing the lower end of the drill bit from shaking and improving drilling accuracy.

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 8 This invention provides a highly stable sliding lathe, comprising:

[0034] Machine base 1, as the core load-bearing foundation of the entire sliding lathe, provides a stable mounting platform for all functional components. A protective cover 2 is installed on the upper surface of machine base 1, which effectively blocks debris and coolant splashes generated during machining, ensuring a safe operating environment. From left to right, the upper surface of machine base 1 is equipped with a rear support assembly 5 and a spindle assembly 3, forming a continuous operational chain from workpiece support to rotary drive. A lateral machining assembly 4 is located on the upper surface of machine base 1, near the spindle assembly 3, which can precisely connect to the workpiece on the spindle to complete lateral drilling and other machining operations. The rear support assembly 5 includes a support platform 51, which is a key load-bearing structure connecting the rear support assembly to machine base 1. 1. Mounted on the upper surface of machine base 1, rigidly connected to machine base 1 by fasteners such as bolts. Support base 52 is mounted on the upper surface of support platform 51, providing an installation reference for other components of the rear support assembly. Guide sleeve 56 is rotatably connected to the inner wall of support base 52, which can rotate synchronously with the workpiece to reduce friction and guide the workpiece positioning. Spindle assembly 3 includes support frame 32, which is the main support frame of spindle assembly 3, ensuring the structural stability when the spindle is running. Support frame 32 is fixedly connected to the upper surface of machine base 1, and the structural rigidity is enhanced by welding or high-strength bolt connection. Pneumatic clamping shaft 31 is rotatably connected to the inner wall of support frame 32, which can quickly realize the clamping and releasing action of workpiece by pneumatic drive.

[0035] Furthermore, a protective sleeve 510 is installed on the left end of the support base 52, which can guide the internal clamping components. A guide seat 57 is installed on the inner wall of the protective sleeve 510, which provides a precise guide trajectory for the sliding of the clamping block 59. The clamping block 59 is slidably connected to the inner wall of the guide seat 57, and the workpiece free end is clamped and fixed by sliding and gathering.

[0036] Furthermore, the right surface of the guide seat 57 is slidably connected to a pressing block 58, which can reciprocate in the horizontal direction. The left end of the pressing block 58 is set in an inclined shape, which facilitates the clamping block 59 to retract towards the center through the inclined plane transmission.

[0037] Furthermore, the rear support assembly 5 also includes a clamping cylinder 53, which provides a power source for the clamping action of the clamping block 59. The clamping cylinder 53 is installed on the upper surface of the support base 52 in a reasonable position that facilitates force transmission. The outer wall of the output shaft of the clamping cylinder 53 is rotatably connected to a transmission rod 54, which can convert the linear motion of the cylinder into a swing motion. The transmission rod 54 is rotatably connected to the left end of the support base 52, and the support base 52 is used as a fulcrum to realize lever-type power transmission. The rotating sleeve 55 is rotatably connected to the inner wall of the transmission rod 54 to reduce friction loss during transmission. The clamping cylinder 53 and the pneumatic clamping shaft 31 are driven by the same air source to ensure the coordination and synchronization of their clamping actions.

[0038] Furthermore, a slider 511 is fixedly connected to the outer wall of the clamping block 59, which moves synchronously with the sliding of the clamping block 59. The slider 511 is elastically connected to the protective sleeve 510 through a return spring 512, which can drive the clamping block 59 to automatically reset after the clamping force is removed.

[0039] Furthermore, the spindle assembly 3 also includes a rotary motor 35, which provides power input for the rotation of the pneumatic clamping shaft 31. The rotary motor 35 is mounted on the upper surface of the machine base 1, forming a compact power layout with the spindle assembly 3. The rotary motor 35 and the pneumatic clamping shaft 31 are connected by a synchronous belt drive to achieve smooth power transmission and speed regulation.

[0040] Furthermore, a brake disc 33 is fixedly connected to the outer wall of the pneumatic clamping shaft 31 and rotates synchronously with the pneumatic clamping shaft 31. A brake block 34 adapted to the brake disc 33 is fixedly connected to the outer wall of the support frame 32. The pneumatic clamping shaft 31 is quickly braked and locked by fitting with the brake disc 33. The brake block 34 is existing technology and has a braking structure inside. After the power is turned on, the brake disc 33 can be fixed by the braking structure.

[0041] Furthermore, the lateral machining component 4 includes a machining cylinder 41, which provides driving force for the feed action of the drill bit 48. A mounting bracket 42 is fixedly connected to the lower surface of the machining cylinder 41, and a stable connection with the machine base 1 is achieved through the mounting bracket 42. The mounting bracket 42 is fixedly connected to the upper surface of the machine base 1 to ensure the structural stability of the lateral machining component 4 during machining. A slide plate 43 is slidably connected to the right end of the mounting bracket 42, which can slide precisely along the vertical direction of the mounting bracket 42. The output shaft of the machining cylinder 41 is fixedly connected to the upper surface of the slide plate 43, driving the slide plate 43 to drive the subsequent machining components to achieve up and down feed.

[0042] Furthermore, a connecting plate 44 is installed on the front surface of the slide plate 43, which serves to connect the slide plate 43 and the drill bit 48 support structure. A support sleeve 47 is fixedly connected to the front surface of the connecting plate 44 to provide radial support for the rotation of the drill bit 48. The drill bit 48 is rotatably connected to the inner wall of the support sleeve 47, and the drilling of the workpiece is completed by high-speed rotation.

[0043] Furthermore, the lateral machining component 4 also includes a drive motor 45, which provides power for the rotation of the drill bit 48. The drive motor 45 and the support sleeve 47 are connected by a gearbox 46, which can realize speed adjustment and power direction conversion. A stabilizing seat 49 is fixedly connected to the lower surface of the support sleeve 47 to enhance the support strength of the lower end of the drill bit 48. The drill bit 48 is rotatably connected to the inner wall of the stabilizing seat 49, which effectively suppresses the shaking of the drill bit 48 during machining to improve drilling accuracy.

[0044] Working principle: Before processing, the bar stock is passed sequentially through the guide sleeve 56 and protective sleeve 510 of the rear support assembly 5 until the end of the bar stock to be processed extends into the pneumatic clamping shaft 31 of the main spindle assembly 3. At this time, the same air source synchronously drives the pneumatic clamping shaft 31 and the clamping cylinder 53 to move: the pneumatic clamping shaft 31 clamps the right end of the bar stock, and the output shaft of the clamping cylinder 53 extends and retracts, driving the transmission rod 54 to swing around the left end of the support seat 52 as the fulcrum. The transmission rod 54 pushes the extrusion block 58 to move horizontally to the left through the rotating sleeve 55 on the inner wall. The inclined surface of the left end of the extrusion block 58 extrudes the clamping block 59, causing the clamping block 59 to converge towards the center along the inner wall of the guide seat 57 and clamp the left end of the bar stock. At the same time, the slider 511 on the outer wall of the clamping block 59 stretches the return spring 512, realizing the synchronous fixation of both ends of the bar stock. During processing, if cutting is required, the rotating motor 35 drives the synchronous belt. The pneumatic clamping shaft 31 drives the bar stock to rotate, and the guide sleeve 56 of the rear support assembly 5 rotates synchronously with the bar stock to reduce friction. If lateral drilling is required, the brake block 34 is energized to fix the brake disc 33 on the outer wall of the pneumatic clamping shaft 31, locking the pneumatic clamping shaft 31 to prevent shaking. Then, the drive motor 45 drives the drill bit 48 in the support sleeve 47 to rotate at high speed through the gearbox 46. At the same time, the processing cylinder 41 pushes the slide plate 43 to slide vertically down along the mounting frame 42. The slide plate 43 drives the drill bit 48 to move down through the connecting plate 44. The drill bit 48 accurately drills the workpiece under the support and guidance of the stabilizing seat 49. After processing, the air source is depressurized, the pneumatic clamping shaft 31 releases the bar stock, the clamping cylinder 53 resets, and the reset spring 512 pulls the slider 511 to reset the clamping block 59, releasing the clamping of the bar stock, and the processed workpiece can be taken out.
