Description

Technical Field

[0001] The present invention relates to the technical field of screw nut processing, and in particular to a screw nut, processing equipment and a processing method. Background Art

[0002] In the field of mechanical manufacturing, screw nut transmission is a common transmission method that converts rotary motion into linear motion and is widely used in various mechanical equipment. With the continuous development of industry, the requirements for the precision, quality and production efficiency of screw nuts are getting higher and higher.

[0003] In the processing of lead screw nuts, the existing technology mainly relies on traditional processing methods and equipment. Among them, in the link of installing the nut blank on the three-jaw chuck, the manual installation method is usually adopted. However, this method has many problems. Manual installation of the nut blank on the three-jaw chuck mainly relies on the experience of the operator. It is necessary to first place the blank in the center of the three-jaw chuck, try to keep it horizontal, and then clamp it with the jaws. It is difficult to ensure that the blank can be kept horizontal every time it is installed. During the installation process, if the blank is offset from the horizontal direction, it is easy for the nut blank and the axis of the three-jaw chuck to not coincide, resulting in coaxiality deviation of the nut blank after installation. This deviation will be further amplified in the subsequent processing process, seriously affecting the processing quality of the lead screw nut.

[0004] As industrial production places higher and higher requirements on the precision and quality of lead screw nuts, the manual installation method in the prior art can no longer meet the production needs, and has the problems of low accuracy and high production cost. Therefore, there is an urgent need for a lead screw nut, processing equipment and processing method to solve the above problems, so as to improve the processing quality and production efficiency of the lead screw nut.

The pressure sensor is arranged in the accommodating cavity, and the top ball is slidably arranged in the through hole. After sliding, the top ball is used to abut or cancel the abutment against the pressure sensor. The two ends of the spring act on the top ball and the inner wall of the accommodating cavity respectively, which are used to provide a force for the top ball to move away from the pressure sensor. The warning light is arranged on the base, and the warning light is electrically connected to the pressure sensor signal.

[0007] Optionally, it further comprises a material storage tube, a material loading rail, a material loading plate and a supporting plate, wherein the material storage tube is arranged on the base, an angle is formed between the material storage tube and the horizontal plane, and the material loading rail is swingably arranged at the lower end of the material storage tube. The loading plate is arranged at one end of the loading rail. After the loading rail swings, the loading plate blocks or opens the lower end opening of the storage tube. The support plate is arranged at the other end of the loading rail, and the support plate is semicircular and used to support the blank. After the loading rail swings, the support plate and the positioning chuck are coaxial or not coaxial. It also includes a CNC three-dimensional mobile platform, a rotating cutter disc, a processing tool and a pusher plate. The CNC three-dimensional mobile platform is arranged on the base, the rotating cutter disc is rotatably arranged on the CNC three-dimensional mobile platform, the processing tool and the pusher plate are both arranged on the rotating cutter disc, there are multiple processing tools, and the pusher plate is used to push the blank on the supporting plate toward the positioning chuck.

[0008] Optionally, it also includes a movable frame, a compressed air release unit and an inflatable sleeve, the movable frame is slidably arranged on the base, the compressed air release unit is arranged on the movable frame, and the inflatable sleeve is arranged on the compressed air release unit, the main shaft is a hollow structure, and after the movable frame slides, the inflatable sleeve is connected to or disconnected from the main shaft, so as to release compressed air into the main shaft.

[0009] Optionally, a rubber ring is further included, which is arranged at the end of the inflation sleeve and is used to contact the end of the main shaft to ensure sealing.

[0010] Optionally, it also includes a transmission shaft and a filter, wherein the transmission shaft is rotatably disposed on the base, there are two transmission shafts, the filter is annular, the filter is sleeved on the two transmission shafts, the filter is located below the positioning chuck, and an angle is formed between the filter and the horizontal plane.

[0011] Optionally, it also includes a chip cleaning roller, which is rotatably disposed on the base, the chip cleaning roller is located at the bottom end of the filter screen and contacts the filter screen, and the surface of the chip cleaning roller has bristles.

[0012] Optionally, a material receiving box is further included, which is arranged on the base and located below the bottom end of the filter screen for receiving workpieces.

[0013] Optionally, a cooling pipe is also included, which is arranged on the base and is used to spray coolant.

[0014] A method for processing a lead screw nut uses a lead screw nut processing device to process the lead screw nut.

[0015] A lead screw nut is manufactured by using a lead screw nut machining method.

[0016] The working principle and beneficial effects of the present invention are: The screw nut processing equipment is mainly composed of a base, a main shaft, a positioning chuck, a movable clamping jaw, a pressure sensor, a top ball, a spring and a warning light. The main shaft is rotatably arranged on the base, and the positioning chuck is coaxially installed on the main shaft. A plurality of movable clamping jaws are arranged on the positioning chuck along the radial sliding direction of the positioning chuck, each movable clamping jaw has a receiving cavity, and the movable clamping jaw is also provided with a through hole connected to the receiving cavity. The pressure sensor is installed in the receiving cavity, the top ball is slidably arranged in the through hole, and the two ends of the spring act on the top ball and the inner wall of the receiving cavity respectively.

[0017] In actual work, under normal conditions, the top ball protrudes from the movable jaws through the through hole. When installing the nut blank, bring the blank close to the positioning chuck, and the blank first contacts the protruding top ball. As the blank continues to approach, the blank will overcome the elastic force of the spring and press the top ball into the through hole, so that the top ball abuts the pressure sensor. Since there are multiple movable jaws and corresponding multiple top balls, only when all the top balls abut the pressure sensor will it be judged that the blank is installed in place, indicating that the blank is well level at this time. After receiving the signal, the pressure sensor sends a signal to the main controller, and the main controller controls the prompt light to light up. At this time, the multiple movable jaws can be operated to slide synchronously to the center of the positioning chuck to clamp the blank together, thereby completing the loading process. In the subsequent processing process, the spindle drives the positioning chuck and the clamped blank to rotate to perform the processing operation of the screw nut.

[0018] It should be noted that, because the positioning chuck rotates during operation, it is difficult to configure the circuit of the pressure sensor. Therefore, the pressure sensor needs to adopt the wireless pressure sensor in the prior art and work through its pressure sensing chip and other components.

[0019] This solution realizes the intelligent installation of the blank, eliminating the need for tedious manual operations and greatly improving production efficiency. During the installation process, through the cooperation of multiple top beads and pressure sensors, the blank is clamped only when the horizontality is good, ensuring the accuracy of the blank installation and effectively avoiding the coaxiality deviation problem caused by the traditional installation method, thereby significantly improving the processing quality of the screw nut. The cooperation of the pressure sensor and the indicator light makes the entire processing process more intelligent, which can respond to the installation status of the blank quickly and accurately, further improving the stability and reliability of production. Finally, the application of this equipment can reduce the scrap rate and reduce the material waste caused by inaccurate manual operation, thereby reducing production costs.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0027] Reference Figure 1 to Figure 7 , which is the first embodiment of the present invention, proposes a screw nut processing equipment, including a base 1, a spindle 2, a positioning chuck 3, a movable clamping jaw 4, a pressure sensor 5, a top ball 6, a spring 7 and a warning light 28, the spindle 2 is rotatably arranged on the base 1, the positioning chuck 3 is coaxially arranged on the spindle 2, and the movable clamping jaw 4 is slidably arranged on the positioning chuck 3 along the radial direction of the positioning chuck 3, The movable clamping jaw 4 has a accommodating cavity 8 therein, and the movable clamping jaw 4 has a through hole 9, and the through hole 9 is communicated with the accommodating cavity 8. The pressure sensor 5 is arranged in the accommodating cavity 8, and the top ball 6 is slidably arranged in the through hole 9. After sliding, the top ball 6 is used to abut or cancel the abutment against the pressure sensor 5. The two ends of the spring 7 act on the top ball 6 and the inner wall of the accommodating cavity 8 respectively, and are used to provide a force for the top ball 6 to move away from the pressure sensor 5. The warning light 28 is arranged on the base 1, and the warning light 28 is electrically connected to the pressure sensor 5.

[0028] In this embodiment, the screw nut processing equipment is mainly composed of a base 1, a main shaft 2, a positioning chuck 3, a movable clamping jaw 4, a pressure sensor 5, a top ball 6, a spring 7 and a warning light 28. The main shaft 2 is rotatably arranged on the base 1, and the positioning chuck 3 is coaxially installed on the main shaft 2. A plurality of movable clamping jaws 4 are slidably arranged on the positioning chuck 3 along the radial direction of the positioning chuck 3, each movable clamping jaw 4 has a receiving cavity 8, and the movable clamping jaw 4 is also provided with a through hole 9 connected to the receiving cavity 8. The pressure sensor 5 is installed in the receiving cavity 8, the top ball 6 is slidably arranged in the through hole 9, and the two ends of the spring 7 act on the top ball 6 and the inner wall of the receiving cavity 8 respectively.

[0029] In actual work, under normal conditions, the top ball 6 protrudes from the movable clamping jaw 4 through the through hole 9. When installing the nut blank, the blank is brought close to the positioning chuck 3, and the blank first contacts the protruding top ball 6. As the blank continues to approach, the blank will overcome the elastic force of the spring 7 and press the top ball 6 into the through hole 9, so that the top ball 6 abuts the pressure sensor 5. Since there are multiple movable clamping jaws 4 and corresponding multiple top balls 6, only when all the top balls 6 abut the pressure sensor 5 will it be judged that the blank is installed in place, which indicates that the levelness of the blank is good at this time. After receiving the signal, the pressure sensor 5 sends a signal to the main controller, and the main controller controls the prompt light 28 to light up. At this time, the multiple movable clamping jaws 4 can be operated to slide synchronously toward the center of the positioning chuck 3 to clamp the blank together, thereby completing the loading process. In the subsequent processing process, the spindle 2 drives the positioning chuck 3 and the clamped blank to rotate to perform the processing operation of the screw nut.

[0030] It should be noted that, because the positioning chuck 3 rotates during operation, it is difficult to configure the circuit of the pressure sensor 5 , so the pressure sensor 5 needs to adopt the wireless pressure sensor 5 in the prior art, and work through its pressure sensing chip and other components.

[0031] This solution realizes the intelligent installation of the blank, without the need for tedious manual operations, and greatly improves production efficiency. During the installation process, through the cooperation of multiple top beads 6 and pressure sensors 5, the blank is clamped only when the horizontality is good, ensuring the accuracy of the installation of the blank, effectively avoiding the coaxiality deviation problem caused by the traditional installation method, thereby significantly improving the processing quality of the screw nut. The cooperation of the pressure sensor 5 and the prompt light 28 makes the entire processing process more intelligent, and can respond to the installation status of the blank quickly and accurately, further improving the stability and reliability of production. Finally, the application of this equipment can reduce the scrap rate and reduce the material waste caused by inaccurate manual operation, thereby reducing production costs.

[0032] Furthermore, it also includes a material storage pipe 10, a material loading rail 11, a material loading plate 12 and a supporting plate 13. The material storage pipe 10 is arranged on the base 1, and there is an angle between the material storage pipe 10 and the horizontal plane. The material loading rail 11 is swingably arranged at the lower end of the material storage pipe 10. The loading plate 12 is disposed at one end of the loading rail 11. After the loading rail 11 swings, the loading plate 12 blocks or opens the lower end opening of the storage tube 10. The support plate 13 is disposed at the other end of the loading rail 11. The support plate 13 is semicircular and is used to support the blank. After the loading rail 11 swings, the support plate 13 is coaxial with the positioning chuck 3 or cancels the coaxiality. It also includes a CNC three-dimensional mobile platform 14, a rotating cutter disc 15, a processing tool 16 and a pusher plate 17. The CNC three-dimensional mobile platform 14 is arranged on the base 1, the rotating cutter disc 15 is rotatably arranged on the CNC three-dimensional mobile platform 14, the processing tool 16 and the pusher plate 17 are both arranged on the rotating cutter disc 15, there are multiple processing tools 16, and the pusher plate 17 is used to push the blank on the supporting plate 13 toward the positioning chuck 3.

[0033] In this embodiment, the screw nut processing equipment also includes a storage tube 10, a loading rail 11, a loading plate 12, a support plate 13, a CNC three-dimensional mobile platform 14, a rotating cutter head 15, a processing tool 16 and a push plate 17. The storage tube 10 is arranged on the base 1, and forms a certain angle with the horizontal plane, so that the blank inside can roll downward by its own weight. The loading rail 11 is swingably arranged at the lower end of the storage tube 10, and the loading plate 12 is located at one end of the loading rail 11. Under normal conditions, the loading rail 11 blocks the lower end opening of the storage tube 10 to prevent the blank from rolling. The support plate 13 is arranged at the other end of the loading rail 11, and is semicircular, and is used to support the blank.

[0034] When loading is required, the loading rail 11 swings downward. At this time, the loading plate 12 pushes the blank at the bottom and blocks the second blank at the same time. As the loading rail 11 continues to swing downward, the bottom blank rolls downward along the loading rail 11 under the action of its own weight until it abuts the supporting plate 13. Since the supporting plate 13 is coaxial with the positioning chuck 3, the blank is also coaxial with the positioning chuck 3 at this time. Next, the rotation of the rotating cutter disc 15 is controlled to switch the push plate 17 to the working position. Then, the movement of the push plate 17 is controlled by the CNC three-dimensional mobile platform 14, and the push plate 17 pushes the blank toward the center of the positioning chuck 3. When the blank approaches the positioning chuck 3, the elastic force of the spring 7 is overcome, and the top ball 6 is pressed into the through hole 9, so that the top ball 6 abuts the pressure sensor 5. Only when multiple top beads 6 are in contact with the pressure sensor 5, it is judged that the blank is installed in place, and the pressure sensor 5 sends a signal to the main controller, and the main controller controls the prompt light 28 to light up, and then the multiple movable jaws 4 can be operated to slide synchronously toward the center of the positioning chuck 3 to clamp the blank together to complete the loading. In the subsequent processing process, the spindle 2 drives the positioning chuck 3 and the clamped blank to rotate, and the CNC three-dimensional mobile platform 14 controls the different processing tools 16 on the rotating cutter head 15 according to the processing requirements to perform turning, milling and other processing on the blank.

[0035] First, through the cooperation of the storage tube 10, the loading rail 11 and the support plate 13, the automatic loading preparation of the blank is realized, which reduces manual intervention and improves the loading efficiency. The swing design of the loading rail 11 and the function of the loading plate 12 ensure that only one blank is pushed out at a time, avoiding confusion and blockage of the blank. Secondly, the coaxial design of the support plate 13 and the positioning chuck 3 ensures the position accuracy of the blank when it is pushed to the positioning chuck 3, laying a good foundation for subsequent processing. Furthermore, the cooperation of the CNC three-dimensional mobile platform 14 and the rotating tool disc 15 makes the switching of the processing tool 16 more flexible and efficient, which can meet the needs of different processing procedures and improve the processing accuracy and quality. Finally, the degree of automation of the entire equipment is improved, which reduces the errors and labor intensity caused by manual operation, reduces production costs, and improves production efficiency.

[0036] Furthermore, it also includes a movable frame 18, a compressed air release unit 19 and an inflatable sleeve 20. The movable frame 18 is slidably arranged on the base 1, the compressed air release unit 19 is arranged on the movable frame 18, and the inflatable sleeve 20 is arranged on the compressed air release unit 19. The main shaft 2 is a hollow structure. After the movable frame 18 slides, the inflatable sleeve 20 is connected to or disconnected from the main shaft 2, so as to release compressed air into the main shaft 2.

[0037] Furthermore, it also includes a rubber ring 21, which is arranged at the end of the inflation sleeve 20, and the rubber ring 21 is used to contact the end of the main shaft 2 to ensure sealing.

[0038] In this embodiment, the screw nut processing equipment further includes a moving frame 18, a compressed air release unit 19, an inflatable sleeve 20 and a rubber ring 21. The moving frame 18 is slidably arranged on the base 1, the compressed air release unit 19 is mounted on the moving frame 18, and the inflatable sleeve 20 is arranged on the compressed air release unit 19.

[0039] In the prior art, most of the spindles 2 of machine tools are hollow structures, mainly to allow the bar to pass through the hollow part of the spindle 2 when processing long bar parts, so that one end of the bar extends out of the front end of the spindle 2 and the other end is supported by the tailstock top. In this way, the long bar can be processed continuously without frequent loading and unloading of the bar, thereby improving the processing efficiency.

[0040] The present solution cleverly utilizes the hollow structure of the spindle 2 in the prior art. When unloading is required, the clamping of the workpiece by the movable jaws 4 is first released, so that the workpiece is in a loose and unclamped state between the multiple movable jaws 4. Next, the movable frame 18 slides, driving the inflatable sleeve 20 to approach and abut the tail end of the spindle 2. At this time, the rubber ring 21 at the end of the inflatable sleeve 20 contacts the end of the spindle 2 to ensure sealing. Then, the compressed air release unit 19 releases compressed air, generating a strong airflow and entering the spindle 2 through the inflatable sleeve 20. Since the spindle 2 is connected to the positioning chuck 3, this strong airflow can blow the unclamped workpiece forward to achieve automatic unloading. The compressed air release unit 19 can adopt a high-pressure jet pump or air cannon device in the prior art.

[0041] First, by setting up the mobile frame 18, the compressed air release unit 19 and the inflatable sleeve 20, the automatic unloading function after the nut processing is realized, without manual operation, which greatly improves the production efficiency. The setting of the rubber ring 21 ensures the sealing of the connection between the inflatable sleeve 20 and the main shaft 2, ensuring that the compressed air can effectively blow the workpiece off. The entire unloading process is fast and accurate, and cooperates with other automatic functions of the equipment, which improves the overall automation level of the equipment and reduces labor intensity and production costs.

[0042] Furthermore, it also includes a transmission shaft 22 and a filter 23. The transmission shaft 22 is rotatably arranged on the base 1. There are two transmission shafts 22. The filter 23 is annular and is sleeved on the two transmission shafts 22. The filter 23 is located below the positioning chuck 3, and there is an angle between the filter 23 and the horizontal plane.

[0043] In this embodiment, the screw nut processing equipment further includes a transmission shaft 22 and a filter 23. The two transmission shafts 22 are rotatably arranged on the base 1, and the annular filter 23 is sleeved on the two transmission shafts 22. The filter 23 is located below the positioning chuck 3 and has a certain angle with the horizontal plane, and is in an inclined state.

[0044] During the operation of the equipment, when the nut is processed, the workpiece is cooled by coolant. The coolant flows downward with the waste chips generated by the processing. The filter 23 can effectively drain the coolant and filter the waste chips on the filter 23, which is convenient for subsequent cleaning work. At the same time, the coolant can be recycled, reducing resource consumption.

[0045] In addition, when the workpiece is blown off by the compressed air after the processing is completed, the filter screen 23 can receive the blown off workpiece. Since the material of the filter screen 23 itself has a certain toughness, it can also effectively buffer the impact force of the workpiece, avoid damage to the workpiece surface due to impact, and ensure the surface quality of the workpiece.

[0046] In addition, the transmission shaft 22 drives the filter screen 23 to perform a cyclic motion. Because the filter screen 23 is arranged at an angle, the workpiece falling on the filter screen 23 is automatically transported downward under the drive of the filter screen 23, which is convenient for subsequent material collection work, further improving the automation degree of the entire processing process.

[0047] First, the setting of the filter 23 realizes the recovery of coolant and the filtration of waste chips, which not only saves resources but also facilitates cleaning, and improves the environmental protection and sustainability of production. Secondly, the buffering effect of the filter 23 on the workpiece effectively protects the surface quality of the workpiece and reduces the scrap rate. Furthermore, the transmission shaft 22 drives the filter 23 to circulate, and the inclined design of the filter 23 enables the workpiece to be automatically transported downward, which greatly facilitates the material collection work, improves production efficiency, and reduces labor intensity. The functions of the entire equipment are more complete and the degree of automation is higher, which provides a strong guarantee for the high-quality and high-efficiency production of screw nuts.

[0048] Furthermore, it also includes a chip cleaning roller 24, which is rotatably disposed on the base 1, the chip cleaning roller 24 is located at the bottom end of the filter screen 23 and contacts the filter screen 23, and the surface of the chip cleaning roller 24 has bristles 25.

[0049] In this embodiment, the lead screw nut processing equipment further includes a chip cleaning roller 24. The chip cleaning roller 24 is rotatably disposed on the base 1, and is located at the bottom end of the filter screen 23 and is in close contact with the filter screen 23. The surface of the chip cleaning roller 24 has bristles 25.

[0050] During the operation of the equipment, as the filter 23 continuously filters the waste chips in the coolant and receives the blown-off workpieces, the waste chips will gradually accumulate on the surface of the filter 23. At this time, the rotating chip cleaning roller 24 uses the bristles 25 on its surface to clean the waste chips on the surface of the filter 23. The chip cleaning roller 24 continues to rotate, and the bristles 25 continuously contact the filter 23, brushing the waste chips on the filter 23 off, preventing excessive accumulation of waste chips from affecting the filtering effect of the filter 23 and the conveying of the workpiece.

[0051] First, the setting of the chip cleaning roller 24 ensures that the filter screen 23 can continue to effectively filter and transport workpieces. The timely cleaning of the waste chips on the surface of the filter screen 23 by the bristles 25 avoids the accumulation of waste chips and the blockage of the filter screen 23, ensuring the smooth recovery of the coolant and the stable transportation of the workpiece. Secondly, the automatic cleaning degree of the equipment is improved, the workload of manual cleaning of the filter screen 23 is reduced, and the labor intensity is reduced. Furthermore, it helps to maintain the good operating state of the equipment, improve production efficiency and product quality, extend the service life of the filter screen 23, and reduce the maintenance cost of the equipment.

[0052] Furthermore, it also includes a material receiving box 26, which is arranged on the base 1. The material receiving box 26 is located below the bottom end of the filter screen 23 and is used to receive workpieces.

[0053] In this embodiment, during the operation of the equipment, when the workpiece is blown onto the filter screen 23, as the transmission shaft 22 drives the filter screen 23 to circulate, the workpiece is automatically transported downwards driven by the filter screen 23 due to the angle between the filter screen 23 and the horizontal plane. When the workpiece reaches the bottom of the filter screen 23, it will naturally fall into the receiving box 26 located below it. The receiving box 26 can stably receive the workpiece that slides off the filter screen 23, realizing the automatic collection of the workpiece.

[0054] First, the setting of the material collecting box 26 makes the collection of workpieces more convenient and quick, without the need to manually pick up the workpieces one by one, which greatly improves the production efficiency. Secondly, the material collecting box 26 can ensure that the workpieces are neat and orderly during the collection process, avoid the workpieces from being scattered and damaged, and ensure the quality of the workpieces. Furthermore, the cooperation between the material collecting box 26 and the filter screen 23 realizes the full automation of the entire processing process from processing, unloading to collecting, reduces labor intensity and production costs, and improves the overall performance and practicality of the equipment.

[0055] Furthermore, a cooling pipe 27 is included. The cooling pipe 27 is arranged on the base 1 and is used to spray cooling liquid.

[0056] In this embodiment, the cooling pipe 27 plays an important role in the processing of the lead screw nut. When the machining tool 16 cuts the blank, a large amount of heat is generated. At this time, the cooling pipe 27 sprays coolant into the machining area, and the coolant can quickly reduce the temperature of the machining area, prevent the workpiece from being deformed or damaged due to overheating, and ensure the machining accuracy and workpiece quality. At the same time, the coolant can also take away the waste chips generated during the cutting process, keep the machining area clean, and help improve the machining efficiency.

[0057] First, the setting of the cooling pipe 27 ensures temperature control during the processing, effectively avoids workpiece quality problems caused by overheating, and improves processing accuracy. Secondly, the coolant can take away waste chips in time, keep the processing area clean, reduce the interference caused by waste chip accumulation to the processing, and improve processing efficiency. Furthermore, the use of the cooling pipe 27 extends the service life of the processing tool 16 and reduces production costs. The performance of the entire equipment is more perfect, providing a strong guarantee for the high-quality processing of the screw nut.

[0058] Furthermore, it also includes a method for processing a lead screw nut, which uses a lead screw nut processing equipment to process the lead screw nut.
