Description

Technical Field

[0001] The invention relates to the technical field of numerically controlled lathes, in particular to a numerically controlled lathe for processing hardware parts. Background Art

[0002] CNC lathes automatically process the parts to be processed according to the pre-programmed processing program. We compile the processing route, process parameters, tool movement trajectory, displacement, cutting parameters and auxiliary functions of the parts into a processing program sheet according to the instruction code and program format specified by the CNC machine tool, and then record the contents of this program sheet on the control medium, and then input it into the CNC device of the CNC machine tool to command the lathe to process parts. It is used for cutting and processing of inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads, and can perform grooving, drilling, reaming, reaming and boring, etc. Hardware refers to tools obtained by processing and casting metals such as gold, silver, copper, iron, and tin. When using CNC lathes to process hardware, the tools are controlled by pre-programmed instructions to perform precision cutting and forming on hardware materials;

[0003] However, when CNC lathes are drilling holes in hardware, long chips are often generated. If these chips are not handled promptly and effectively, they may be entangled in the drill bit and difficult to discharge. The entanglement of long chips may cause the drill bit to deviate from the predetermined path, affecting the position accuracy and size accuracy of the hole. For example, when the drill bit is offset due to the entanglement of long chips, it will cause inconsistent hole diameters or position deviations, resulting in the scrapping of parts or the need for secondary processing. The pulling and entanglement of long chips will leave scratches or indentations on the surface of the workpiece, reducing the appearance and quality of the product. At the same time, chip entanglement will increase the friction between the drill bit and the workpiece, resulting in accelerated tool wear. For example, the cutting edge of the drill bit that has been in friction with the chips for a long time will easily become blunt, thereby reducing the effective service life of the tool, and if a large amount of chips are not effectively discharged, they will accumulate around the machine tool, increasing the time and difficulty of cleaning work. In view of this, we propose a CNC lathe for hardware processing. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the CNC lathe used for hardware processing, a spring groove is provided on the surface of the limit groove provided on the surface of the drill, and a connecting spring connected to the mounting plate is installed inside the spring groove. When drilling holes in the hardware, the elastic force of the connecting spring retracts the mounting plate into the limit groove, and the mounting plate with the chip breaker blade is rotated into the hardware along with the drill. While drilling holes in the hardware, the chip breaker blade cuts off long chips to avoid winding problems caused by too long chips. When the drilling is completed, the drill gradually rises upward and separates from the hardware, and the elastic force of the connecting spring can push the mounting plate to rotate outward. During the upward rotation process, the mounting plate can bring out the drill chips remaining in the drill hole, reducing the residual chips in the drill hole. At the same time, the spiral groove design on the outer wall of the drill can guide the cutting, so that the cutting is discharged upward, avoiding equipment failure problems caused by cutting blockage.

[0021] 2. In the CNC lathe used for hardware processing, the design of multiple chip breaking blades can effectively cut long chips into small sections when the drill bit rotates to drill holes, avoiding shutdown and cleaning caused by long chips entanglement, significantly improving processing efficiency, and avoiding the problem of long cuttings entangled in the drill bit causing the drill bit to deviate from the predetermined path. At the same time, effective chip breaking reduces the possibility of chips scratching the workpiece surface and improves the surface quality of the workpiece; the parallel arrangement of the chip breaking blades makes the cutting force evenly distributed, avoiding tool damage caused by excessive local force, and at the same time, the parallel arrangement of the chip breaking blades forms multiple chip breaking points, so that the chips are broken multiple times during the generation process.

[0022] 3. In the CNC lathe used for hardware processing, the adjustment rod can slide up and down in the cavity inside the tool holder through the setting of the elastic spring. The elastic spring is set long enough and can be adjusted according to the different heights of the hardware. It is convenient and simple. No matter when, the bottom end of the collecting plate is in contact with the surface of the hardware, the hardware can be further limited and fixed, ensuring stability and precision during the processing. At the same time, when the drilling is completed and the drill rises upward and separates from the hardware, the elastic force of the connecting spring can push the mounting plate to rotate outward. The open space reserved at the bottom of the two collecting plates will not affect the outward rotation of the mounting plate. While rotating outward, the mounting plate pushes the drill chips inside the drill hole into the collecting plate. At this time, the inside of the collecting plate also plays a role in collecting cuttings. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] CNC lathes automatically process the parts to be processed according to the pre-programmed processing program. We compile the processing route, process parameters, tool motion trajectory, displacement, cutting parameters and auxiliary functions of the parts into a processing program sheet according to the instruction code and program format specified by the CNC machine tool, and then record the contents of this program sheet on the control medium, and then input it into the CNC device of the CNC machine tool to command the lathe to process parts. It is used for cutting and processing of inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads, and can perform grooving, drilling, reaming, reaming and boring, etc. Hardware refers to tools obtained by processing and casting metals such as gold, silver, copper, iron, and tin. When using CNC lathes to process hardware, the tools are controlled by pre-programmed instructions to perform precision cutting and forming on hardware materials.

[0037] See also Figure 1-Figure 7 As shown, this embodiment provides a CNC lathe for hardware processing, including a lathe body 100. Considering that long chips are often generated in the drilling operation of hardware, if these chips are not promptly and effectively processed, they may be entangled on the drill bit, affecting the drilling quality and efficiency and shortening the tool life. Therefore, the details are as follows: the lathe body 100 specifically includes a spindle box 102, and a drilling assembly 300 is arranged inside the spindle box 102. The drilling assembly 300 includes a tool holder 301 and a drill 302. The tool holder 301 is used to install and fix the drill 302, and the drill 302 is used to drill the hardware;

[0038] The outer wall of the drill bit 302 is provided with a limit groove 3020, and the inner part of the limit groove 3020 is rotatably connected with an adjustment component 400. The outer wall of the adjustment component 400 is provided with a plurality of chip breaking blades 4020, and the chip breaking blades 4020 are used to cut long chips;

[0039] A cavity 3010 is provided inside the tool holder 301 , and an auxiliary component 500 is installed inside the cavity 3010 . The auxiliary component 500 is used to assist the chip breaker 4020 .

[0040] Considering that CNC lathes often produce long chips when drilling hardware, if these chips are not handled promptly and effectively, they may be entangled in the drill bit and difficult to discharge. The entanglement of long chips may cause the drill bit to deviate from the predetermined path, affecting the position accuracy and size accuracy of the hole. For example, when the drill bit is offset due to the entanglement of long chips, it will cause inconsistent hole diameters or position deviations, resulting in the scrapping of parts or the need for secondary processing. The pulling and entanglement of long chips will leave scratches or indentations on the surface of the workpiece, reducing the appearance and quality of the product. At the same time, chip entanglement will increase the friction between the drill bit and the workpiece, resulting in accelerated tool wear. For example, the cutting edge of the drill bit that has been in friction with the chips for a long time is prone to become blunt, thereby reducing the effectiveness of the tool. The service life of the machine tool is improved, and if a large amount of chips are not effectively discharged, they will accumulate around the machine tool, increasing the time and difficulty of cleaning. Therefore, the design of multiple chip breaking blades 4020 can effectively cut long chips into small sections when the drill 302 rotates to drill, avoiding downtime for cleaning due to the entanglement of long chips, significantly improving the processing efficiency, avoiding the problem of long cuttings entangled in the drill bit causing the drill bit to deviate from the predetermined path, and at the same time, effective chip breaking reduces the possibility of chips scratching the workpiece surface, thereby improving the surface quality of the workpiece; the design of the adjustment component 400 can take out the drill chips remaining in the borehole after drilling is completed, reducing the residual chips in the borehole and avoiding equipment failure caused by cutting blockage.

[0041] Furthermore, a spiral groove is provided on the outer wall of the drill bit 302 to transport the cutting fluid to the cutting area through the spiral groove, and further guide the drill chips, so as to efficiently guide the chips to be discharged along the spiral groove to avoid chip accumulation.

[0042] Considering that long chips are often generated when CNC lathes perform drilling operations on hardware, and the long chips may be entangled on the drill bit and difficult to be discharged, a spring groove 3021 is provided on the surface of the limit groove 3020, and the adjustment component 400 includes a connecting spring 401, one end of which is arranged inside the spring groove 3021, and the adjustment component 400 also includes a mounting plate 402, the surface of the mounting plate 402 is connected to the end of the connecting spring 401, and the blade of the chip breaker 4020 is transversely arranged on the surface of the mounting plate 402, and a plurality of chip breaker blades 4020 are arranged in parallel from top to bottom on the surface of the mounting plate 402;

[0043] When drilling holes in hardware, the mounting plate 402 is retracted into the limiting groove 3020 through the elastic force of the connecting spring 401, and the mounting plate 402 with the chip breaker blade 4020 is rotated into the hardware along with the drill bit 302. While drilling holes in the hardware, the chip breaker blade 4020 cuts off long chips to avoid entanglement problems caused by too long chips. When the drilling is completed, the drill bit 302 gradually rises upward and separates from the hardware. The elastic force of the connecting spring 401 can push the mounting plate 402 to rotate outward. During the upward rotation process, the mounting plate 402 can bring out the drill chips remaining in the drill hole, thereby reducing the residual chips inside the drill hole.

[0044] Specifically, the auxiliary component 500 includes an adjustment rod 501, two of which are symmetrically arranged. The top of the adjustment rod 501 is arranged inside the cavity 3010, and the bottom end passes through the tool holder 301 to the outside, and the bottom end is connected to a collecting plate 5011. The adjustment rod 501 slides in the cavity 3010 of the tool holder 301 to adjust according to different heights of hardware. The auxiliary component 500 also includes an elastic spring 502, which is arranged on the outer wall of the adjustment rod 501, and the top of the elastic spring 502 is connected to the lower surface of the tool holder 301, and the bottom end is connected to the upper surface of the collecting plate 5011, so as to adjust the lifting height of the adjustment rod 501 through the elastic force of the elastic spring 502;

[0045] By setting the elastic spring 502, the adjustment rod 501 can slide up and down in the cavity 3010 inside the tool holder 301. The elastic spring 502 is set long enough and can be adjusted according to the different heights of the hardware. It is convenient and simple. The bottom end of the collecting plate 5011 is in contact with the surface of the hardware at any time, and the hardware can be further limited and fixed, ensuring stability and precision during the processing; when the drilling is completed, the drill bit rises upward and separates from the hardware. At this time, the bottom end of the collecting plate 5011 is still in contact with the surface of the hardware, and the mounting plate 402 pushes the drill chips inside the drill hole into the collecting plate 5011 while rotating outward.

[0046] It should be noted that the collecting plate 5011 is configured as a three-sided fence structure, and an open space is reserved at the bottom between the two collecting plates 5011. The shape and size of the drill 302 are adapted to the space, and the hardware is drilled through the space. During the operation of the high-speed rotating drill 302, the flying metal chips and vibrations can be blocked by the fence-shaped collecting plate 5011 to protect the operator from injury. At the same time, after the processing is completed, the operator can quickly clean up the metal chips and other debris on the collecting plate 5011 to keep the working environment clean and tidy and extend the service life of the equipment.

[0047] In order to prevent the adjusting rod 501 from being separated from the cavity 3010 inside the tool holder 301 during the sliding process, a baffle 5010 is fixedly connected to the upper surface of the adjusting rod 501. The shape and size of the baffle 5010 are adapted to the internal space of the cavity 3010. Through the adaptation of the baffle 5010 and the cavity 3010, it can be prevented that the adjusting rod 501 is separated from the tool holder 301 when sliding down to a certain position. The baffle 5010 will be engaged inside the cavity 3010, thereby further limiting the position of the adjusting rod 501.

[0048] In addition, a plurality of limiting grooves 3020 are provided in a circular array around the outer wall of the drill bit 302 so that the drill bit 302 is subjected to a more balanced force during the processing.

[0049] In order to enable the hardware to be drilled, the lathe body 100 also includes a bed 101, a workbench 103 and a drive system 104. The workbench 103 is located above the bed 101 and can be connected to the bed 101 through a linear guide or a sliding guide. The drive system 104 is located on the side of the bed 101 and is connected to the workbench 103 through a mechanical transmission component.

[0050] The upper surface of the workbench 103 is slidably connected with a fixture 1030, which is used to clamp and fix the hardware. By placing the workpiece on the working surface of the fixture 1030, it is ensured that the workpiece is in full contact with the contact surface of the fixture 1030 and is in the correct processing position. Afterwards, the clamping assembly in the fixture 1030 is used to fix the hardware to prevent it from being displaced during the processing;

[0051] The drive system 104 is used to convert electrical energy into mechanical energy to control the movement of the workbench 103 and the movement path of the drill 302 on the workpiece. The drive system 104 is provided with electrical energy by a power source, which can be in the form of batteries, supercapacitors or generators. The driver receives signals from the control system and converts them into appropriate current or voltage signals to drive the motor. After the motor receives the current or voltage signal from the driver, it converts it into mechanical energy, namely torque and rotational motion. The torque enables the equipment to operate, thereby completing the conversion of electrical energy into mechanical energy.

[0052] In summary, the working principle of the present invention is as follows:

[0053] The three-dimensional image and processing parameters of the hardware to be processed are input into the CNC system to formulate a processing plan. Then, the CNC system generates a CNC program according to the instructions, including the spindle speed, feed speed, processing route, etc., and runs the CNC program. The operator places the hardware on the fixture 1030 for limit fixation and starts the processing and drilling process. The CNC system sends instructions according to the program and starts the drive system 104 to perform drilling operations on the hardware. When the processing program is executed, the CNC system issues a stop command to end the processing process, and the hardware can be further processed.

[0054] During the drilling process of the hardware, the elastic force of the connecting spring 401 retracts the mounting plate 402 into the limiting groove 3020, and the mounting plate 402 with the chip breaker blade 4020 rotates into the hardware along with the drill 302, and the chip breaker blade 4020 cuts off the long chips while drilling the hardware, thereby avoiding the entanglement problem caused by the chips being too long. When the drilling is completed, the drill 302 gradually rises up and leaves the hardware, and the elastic force of the connecting spring 401 can push the mounting plate 402 to rotate outward, and the mounting plate 402 is installed. During the upward rotation process, the plate 402 can bring out the drill cuttings remaining inside the drill hole, thereby reducing the residual chips inside the drill hole. At the same time, the spiral groove design on the outer wall of the drill bit 302 can guide the cuttings and discharge the cuttings upward. Whenever the bottom end of the collecting plate 5011 is in contact with the surface of the hardware, the open space reserved at the bottom end of the two collecting plates 5011 will not affect the outward rotation of the mounting plate 402. The mounting plate 402 pushes the drill cuttings inside the drill hole into the collecting plate 5011 while rotating outward.
