Description

Technical Field

[0001] The invention relates to the technical field of nut production and drilling, in particular to a multifunctional drilling machine tool for nut production. Background Art

[0002] A nut is a mechanical part used with a bolt or a screw. It is usually in the shape of a hexahedron or other polygon with threads inside. Its function is to provide clamping force when fastening or connecting two or more parts by cooperating with the threads of the bolt, thereby making the connection structure stable and reliable. It is widely used in many industries such as machinery manufacturing, construction, automobiles, aerospace, etc.

[0003] The drilling machine tool for nut production is a device specially used for the drilling process in the nut processing. It generally has a high-precision positioning and clamping device, which can accurately fix the nut blank. The spindle of the machine tool drives the drill bit to rotate at high speed. According to the pre-set program or process requirements, it drills holes that meet the dimensional accuracy and quality standards at specific positions of the nut. This type of drilling machine tool plays a key role in the nut production line. Its processing accuracy and efficiency directly affect the quality of the nut products and the production speed of the entire production process. Through automated control and advanced cutting technology, it can achieve efficient drilling processing of nuts of different specifications to meet the needs of large-scale industrial production.

[0004] However, existing drilling machines for nut production often have many disadvantages:

[0005] First, in the process of nut drilling, in order to cool the tool and suppress the spread of dust, a large amount of cutting fluid is usually sprayed. Although the cutting fluid can play a role in cooling, dust reduction and lubrication, it will undoubtedly lead to a substantial increase in the cost of use. In addition, a large amount of metal debris will be mixed in the cutting fluid, which is extremely difficult to deal with later. It will also pollute the machine tool workbench, causing great inconvenience and trouble to the actual production operation. It not only increases the production cost, but also may affect the processing accuracy and equipment stability. For example, the cutting fluid containing metal debris will accumulate on the surface of the workbench for a long time, which may cause the workbench flatness to decrease, thereby affecting the accuracy of nut drilling;

[0006] Secondly, after the nut is punched, metal debris often remains on the inner wall of the hole, which needs to be cleaned with special cleaning equipment. This undoubtedly adds extra labor to the nut production, which not only increases equipment investment and labor costs, but also prolongs the production cycle. In addition, if the cleaning process is improper, it may also damage the processed surface of the nut and affect product quality. For example, excessive cleaning may cause scratches or deformation on the threaded part of the nut, reducing the connection performance and reliability of the nut.

[0007] Third, high-intensity noise is often generated during drilling operations. This noise seriously interferes with the working environment and causes strong discomfort to workers. If workers are in this noisy environment for a long time, they may suffer from health problems such as hearing loss. It also distracts workers’ attention, reduces work efficiency and quality, and increases the risk of operational errors.

[0008] Fourth, when drilling, the tool rotates at high speed, and the metal scraps generated are splashed everywhere due to centrifugal force. This not only greatly increases the difficulty of collecting the scraps, but also poses a serious safety hazard to the workers. It may scratch the workers' skin or damage their eyes, etc., seriously affecting the safety and orderliness of the workplace. At the same time, it will also cause pollution and damage to the surrounding equipment and the environment. For example, metal scraps splashing onto other precision parts may cause them to jam or be damaged;

[0009] Fifth, when collecting metal scraps, existing drilling machines usually use a vacuum cleaner in conjunction with a collection box. However, in actual use, these scraps are often loose. Therefore, some scrap collection devices usually extrude these metal scraps collectively to facilitate their later storage and transportation and reduce the scattering of metal powder. However, in actual use, although this method is convenient for later transportation and storage, whenever scraps need to be collected, personnel are required to manually stop the machine and then take out the scraps from the collection box, which will undoubtedly cause a certain amount of time loss and is not conducive to continuous drilling processing, which can easily have a great impact on the actual processing efficiency. In addition, the collective extrusion of metal scraps will also form larger metal blocks, which will be very time-consuming and laborious in the later transportation and retrieval process. If a small amount of extrusion is performed into blocks, it will cause the workers to frequently take out the scraps, which increases the labor burden of the workers and affects their punching efficiency, which in turn causes great trouble to actual use.

[0019] Compared with the prior art, the beneficial effect of the present invention is that when the device is drilling holes in nuts, the nut sorting machine can be used to sort multiple nuts first, and then the multiple nuts are sequentially transported to the positioning frame of the positioning assembly, and then the servo rotary motor is used to drive the multiple positioning frames to perform precise rotational motion, so that the nuts can be driven to move to the bottom of the drilling tool, and then the drilling tool is driven down by the hydraulic lifting cylinder and the nuts are punched by the action of the drilling motor. In the process of drilling and descending, the movable sleeve will slowly shrink into the inside of the fixed cylinder, and then the external compressed gas can be injected into the cooling vortex tube to generate cold air, and the cold air will be discharged from the multiple cooling outlets through the cavity and enter the movable sleeve, so that the high-temperature drilling tool can be cooled, and the metal debris generated by the processing can be collected and transferred to the inside of the installation barrel by the negative pressure of the vacuum cleaner, reducing the cost increase caused by the use of cutting fluid, and the cost is lower than the existing cooling and dust reduction methods, avoiding the use of a large amount of cutting fluid, which makes it difficult to clean the workbench in the later stage.

[0020] Secondly, after drilling the nut, the positioning component will rotate again at a fixed angle, and then reach the bottom of the hollow tube. At this time, while drilling the next nut, the hollow tube can be synchronously lowered so that the hollow tube can be inserted into the hole just completed, and then injected with external compressed gas. At this time, since the multiple jet ports are inclined, the hollow tube will be driven to rotate due to the force of the airflow during the compressed gas injection process. The rotating seat carrying the ball on the top of the hollow tube can reduce its friction, so that it can smoothly drive the hollow tube to rotate, and then the circumferential inner wall of the hole is fully cleaned by airflow. The fine dust cleaned by the airflow can be collected and transferred to the inside of the installation barrel through the second dust suction port on the outer wall of the hollow ring, thereby reducing the attachment of impurities to the inner wall after drilling, and avoiding the trouble of adding additional cleaning equipment to clean the nut;

[0021] In addition, during the drilling process, the drilling area of ​​the device can be shielded by the fixed cylinder and the movable sleeve, which can greatly reduce the spread of noise, thereby achieving a certain purpose of reducing noise in the actual processing environment and reducing the discomfort caused by the diffusion of high-frequency noise to the workers;

[0022] Moreover, the fixed cylinder and the movable sleeve can also block the splashing metal scraps generated by the processing due to the shielding, thereby reducing the safety hazards caused by the splashing of metal scraps, and can better cooperate with the vacuum cleaner to collect the metal scraps generated by the processing, reducing the inconvenience caused by the splashing of metal scraps;

[0023] Secondly, when the metal scraps generated during processing are collected and transferred to the installation barrel, its driving motor can rotate to drive the spiral feed rod to rotate, so that it can continuously transport the metal scraps to the bottom, and in the process of the spiral feed rod rotating, the scraper frame with a rubber cleaning scraper on its circumferential outer wall can also scrape the metal scraps on the inner wall of the installation barrel to reduce the occurrence of metal scraps. When the metal scraps are continuously transported to the bottom of the installation barrel, the metal scraps will be squeezed due to the continuous force. During the squeezing process, the pressure sensor inside the closing plate will continue to sense. When the pressure reaches a certain threshold, its cylinder will drive the moving frame to retreat to release the obstruction to the bottom of the installation barrel. At this time, the scraps compressed into a cylindrical shape will fall to the bottom of the collection box for collection due to gravity and the vibration motor. The controller can count once when the threshold is exceeded. When the count reaches a certain threshold, the controller can activate the sound alarm to remind the staff to clean up the waste cylindrical blocks in time. The drilling machine integrates cooling, sound insulation, splash prevention, nut drilling inner wall cleaning, waste collection and waste treatment, thereby better improving the overall functionality of the drilling machine. Moreover, its waste treatment method is more efficient than the waste chip treatment device on the traditional drilling machine. Even when the drilling machine is continuously processing, its waste can be cleaned up in time, reducing the trouble caused by frequent shutdowns to remove metal waste, further improving the work efficiency of the drilling machine during processing, and smaller metal cylindrical blocks are more convenient to carry during subsequent unified collection, reducing the situation where the waste metal blocks are too large to be handled, thereby improving its convenience of use.

[0036] In some embodiments: the nut sorting machine 120 model can use Rongyi nut feeder, which belongs to the existing technology and is convenient for sorting nuts and conveying them to the positioning frame 270.

[0038] In some embodiments, the second pressing cylinder 361 and the first pressing cylinder 140 are used to limit and fix the nut when drilling and cleaning the inner wall, thereby reducing the phenomenon of its deviation.

[0039] A fixing plate three 400 is also provided on the outer wall of the other side of the mounting frame 300, and an extrusion assembly is provided on the outer wall of the fixing plate three 400, and the extrusion assembly includes a mounting barrel 410. A collecting assembly is provided on the outer wall of one side support foot 110, and the collecting assembly includes a collection box 500.

[0040] Specifically, a fixing plate 210 is provided at the bottom of the fixing seat 200, a servo rotary motor 220 is provided on the top of the fixing plate 210, an output end of the servo rotary motor 220 is connected to a rotating block 230, a rotating joint 240 is provided on the top of the rotating block 230, and a nut positioning frame 270 is provided on the circumferential outer wall of the rotating block 230.

[0041] In some embodiments: the rotary joint 240 is a prior art, which facilitates air supply when the multiple material-blocking cylinders 260 rotate.

[0042] Furthermore, a connecting plate 250 is provided on the top of the plurality of nut positioning frames 270, and a material-repelling cylinder 260 is provided on the outer wall of the connecting plate 250.

Taking TiN coated tools as an example, the TiN coating has a golden appearance and its friction coefficient is low. During the cutting process, the interaction between the coating and the workpiece material can effectively reduce the friction. When the tool cuts into the workpiece, the coating is like a layer of microscopic lubricant, making the cutting process smoother. This method is particularly suitable for high-speed cutting and dry cutting, so that it can provide a certain lubrication effect without using cutting fluid.

[0046] Furthermore, a cooling vortex tube 341 is provided on the outer wall of the fixed cylinder 340, a cavity 342 is opened inside the fixed cylinder 340, a cooling air outlet 343 is opened on the circumferential inner wall of the fixed cylinder 340, a movable sleeve 344 is also slidably sleeved on the circumferential inner wall of the fixed cylinder 340, a dust suction pipe 345 is provided on the circumferential outer wall of the movable sleeve 344, a connecting cylinder 346 is provided at the bottom of the inner cavity of the movable sleeve 344, and a dust suction port 347 is opened on the circumferential outer wall of the connecting cylinder 346.

[0049] It is worth noting that a dust screening net 420 is clamped on the top of the mounting barrel 410, and a driving motor 430 and a vacuum cleaner 440 are also provided on the top of the mounting barrel 410. The vacuum end of the vacuum cleaner 440 is connected to a dust collecting pipe, and the end of the dust collecting pipe is connected to the top of the sleeve hollow ring 355. The end of the vacuum pipe 345 is connected to the vacuum end of the vacuum cleaner 440, so as to facilitate the collection of the cleaned metal debris.

[0050] In addition, the output end of the driving motor 430 is connected to a spiral feed rod 431, and a scraper frame 432 is provided on the circumferential outer wall of the spiral feed rod 431.

It can withstand extremely high pressure and load, and is suitable for conveying large and heavy metal scraps or using under harsh working conditions. By reasonably adding alloy elements, good wear resistance, corrosion resistance and high temperature resistance can be obtained, and the service life and reliability of the spiral feed rod can be improved. The above belongs to the prior art. The outer wall of the bottom circumference of the spiral feed rod 431 is also provided with a leveling block made of alloy material, which can ensure that the top of the metal cylindrical block is flat during the extrusion process, and can ensure the tightness of the metal scrap after extrusion, so that it is easy to extrude into a more precise metal scrap cylindrical block.

[0053] Working principle of the present invention: When drilling holes in nuts, the device can first use the nut sorting machine 120 to sort multiple nuts, and then transport the multiple nuts to the positioning frame 270 of the positioning assembly in sequence, and then use the servo rotary motor 220 to drive the multiple positioning frames 270 to perform precise rotational movement, so that it can drive the nuts to move to the bottom of the drilling tool, and then drive the drilling tool to descend through the hydraulic lifting cylinder 320 and perform drilling processing on the nuts through the action of the drilling motor 331. During the drilling and descending process, the movable sleeve 334 will slowly shrink into the fixed cylinder 340, and then the external compressed gas can be injected into the cooling vortex tube 341 to generate cold air, and the cold air will pass through the cavity 342 from the multiple cooling The air is discharged from the outlet 343 and enters the movable sleeve 334, so that the high-temperature drilling tool can be cooled, and the metal debris generated by the processing can be collected by the negative pressure of the vacuum cleaner 440 and transferred to the installation barrel 410, reducing the cost increase caused by the use of cutting fluid. Compared with the existing cooling and dust reduction methods, the cost is lower, and the use of a large amount of cutting fluid causes the trouble of difficult cleaning of the workbench in the later stage. Secondly, after drilling the nut, the positioning component will rotate again at a fixed angle, and then reach the bottom of the hollow tube 354. At this time, while drilling the next nut, the hollow tube 354 can be synchronously lowered so that the hollow tube 354 can be inserted into the hole just completed, and then it can be used Injected with external compressed gas, at this time, since the multiple jet ports 357 are inclined, the hollow tube 354 will be driven to rotate due to the force of the airflow during the compressed gas injection process, and the rotating seat 352 carrying the ball 353 on the top of the hollow tube 354 can reduce its friction, so that it can smoothly drive the hollow tube 354 to rotate, and then the circumferential inner wall of the hole is fully cleaned by airflow, and the fine dust cleaned by the airflow can be collected and transferred to the inside of the installation barrel 410 through the dust suction port 356 on the circumferential outer wall of the hollow ring 355, thereby reducing the adhesion of impurities on the inner wall after punching, avoiding the trouble of adding additional cleaning equipment to clean the nut, and the device is in the process of punching, and its punching area It can be shielded by the fixed cylinder 340 and the movable sleeve 344, which can greatly reduce the spread of noise, thereby achieving a certain purpose of reducing noise in the actual processing environment and reducing the discomfort caused by the spread of high-frequency noise to the workers. In addition, the fixed cylinder 340 and the movable sleeve 344 can also block the splashing metal chips generated by the processing due to the shielding reason, thereby reducing the safety hazards caused by the splashing of metal chips, and can better cooperate with the vacuum cleaner 440 to collect the metal chips generated by the processing, reducing the inconvenience caused by the splashing of metal chips. Secondly, when the metal chips generated during the processing are collected and transferred to the installation barrel 410, the driving motor 430 can rotate to drive the spiral feed rod 431 to rotate.The scrap metal can be continuously transported to the bottom, and during the rotation of the spiral feeding rod 431, the scraper frame 432 with the rubber cleaning scraper 433 on its circumferential outer wall can also scrape the metal debris on the inner wall of the installation barrel 410 to reduce the occurrence of metal debris agglomeration. When the metal debris is continuously transported to the bottom of the installation barrel 410, the metal debris will be squeezed due to the continuous force. During the squeezing process, the pressure sensor 562 inside the closing plate 563 will continuously sense. When the pressure reaches a certain threshold, the cylinder 550 will drive the moving frame 560 to retreat to remove the obstruction to the bottom of the installation barrel 410. At this time, the waste debris compressed into a cylindrical shape will fall to the bottom of the collecting box 500 for collection due to gravity and the vibration motor 450. 62 triggers a threshold once, and the controller 562 counts once. When the count reaches a certain threshold, the controller 562 can start the sound alarm 561 to alarm, reminding the staff to clean up the waste cylindrical block in time. The drilling machine integrates cooling, sound insulation, splash prevention, nut drilling inner wall cleaning, waste collection and waste treatment, which can better improve the overall functionality of the drilling machine. Moreover, its waste treatment method is more efficient than the waste chip treatment device on the traditional drilling machine. Even when the drilling machine is continuously processing, its waste can be cleaned up in time, reducing the trouble caused by its frequent shutdown to remove metal waste, further improving the work efficiency of the drilling machine during processing, and the metal cylindrical blocks with lower density are more convenient to carry when they are collected in a unified manner later.

[0054] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as belonging to the scope of protection determined by the claims submitted for the present invention.
