Description

Technical Field

[0001] This application relates to the technical field of butterfly nut production and processing equipment, and in particular to a butterfly nut processing equipment and method. Background Technology

[0002] A winged nut is a type of nut shaped like a butterfly. Winged nuts can be classified by manufacturing process into cold-forged winged nuts, cast winged nuts, and stamped winged nuts; and by shape into two basic types: square-winged and round-winged. Because of their double wings, winged nuts can be manually tightened or loosened without the need for tools, making them very versatile.

[0003] like Figure 1 The wing nut shown comprises an interconnected cylindrical portion 100 and a side plate portion 200. A through hole 300 is formed in the cylindrical portion, and internal threads are milled into the inner wall of the through hole. The outer wall of the side plate portion also requires milling. It is generally machined using a CNC lathe. A CNC lathe is a precision machining equipment controlled by a computer; it is an automated machining device developed from a general milling machine. The main tasks of CNC machining are programming and automatically controlling the machining path.

[0004] During machining, the wing nut needs to be held in place to ensure product quality and aesthetics. Currently, in the machining field, wing nuts are typically secured using manual clamps or general-purpose mechanical clamps. While manual clamps are simple in structure, they are inefficient and their positioning accuracy is greatly affected by human factors.

[0005] The main methods for fixing wing nuts using general mechanical fixtures include: ① Three-jaw chuck clamping: the outer edge of the nut is radially clamped by the jaws, but this can easily cause deformation of thin-walled wing nuts; ② Magnetic fixture adsorption: the bottom surface of the nut is fixed by magnetic force, but it cannot limit lateral displacement and is prone to vibration during milling; ③ Hydraulic expansion mandrel: the mandrel is inserted into the inner hole of the nut and then hydraulically expanded and fixed, but it is only suitable for inner hole machining and cannot be used for outer edge milling.

[0006] The main drawbacks of the existing technology are: ① uneven clamping force distribution leads to local deformation of the wing nut; ② poor lateral positioning causes milling vibration, affecting the thread machining accuracy; ③ the fixture structure is complex, and the adjustment is time-consuming when changing workpieces, making it difficult to adapt to the needs of mass production.

[0007] Regarding the aforementioned technologies, existing fixtures cannot properly hold wing nuts during the processing of wing nuts, which can easily affect product quality and therefore needs to be improved. Summary of the Invention

[0008] To improve the stability of wing nut processing and ensure product quality, this application provides a wing nut processing device.

[0009] Firstly, the wing nut processing device provided in this application adopts the following technical solution: A wing nut processing device includes a mounting plate, a fixed base, a clamping component, a positioning plate, and a side-pressing assembly. Both ends of the mounting plate are connected to a machine tool. The fixed base is located on one side of the mounting plate and has a positioning groove for positioning the wing nut. The positioning plate is locked to the fixed base by the clamping component and is used to press the cylindrical portion of the wing nut. A clearance hole communicating with a through hole is provided through the positioning plate. The side-pressing assembly is mounted on the mounting plate and is used to press the side plate portion of the wing nut. The side-pressing assembly includes a linear cylinder, a lifting block, and a pressing block. The linear cylinder is located on the other side of the mounting plate. The lifting block is raised and lowered on the mounting plate and connected to the piston rod of the linear cylinder. A limiting hole is formed through the mounting plate. The pressing block is integrally connected to the lifting block and passes through the limiting hole. The pressing block is located on one side of the fixed base and is used to press against the side plate portion.

[0010] By adopting the above technical solution, before processing, the operator first clamps the wing nut into the positioning groove, and then uses the clamping component to press the positioning plate onto the fixed seat. Next, a linear cylinder is used to control the lifting block to move upward, thereby moving the pressure block upward and pressing the side plate onto the fixed seat, thus completing the fixing of the wing nut. During processing, the machining head can penetrate into the through hole of the cylindrical part through the clearance hole for machining. The wing nut is clamped by the positioning plate and the side pressure component, improving the stability of the wing nut during machining and reducing the possibility of shaking. After the internal thread of the cylindrical part is machined, the clamping effect of the side pressure component on the side plate is released, exposing the outer surface of the side plate, which is then machined using a CNC lathe.

[0011] Preferably, the clamping component is a fastening bolt, which passes through the positioning plate and is screwed onto the fixed seat; it also includes a first spring, the two ends of which are respectively connected to the positioning plate and the fixed seat, the fastening bolt passes through the first spring, and the spring force direction of the first spring is parallel to the lifting direction of the lifting block.

[0012] By adopting the above technical solution, the fastening bolt passes through the positioning plate and is screwed onto the fixed seat, relying on the screw force to achieve fixation. When the fastening bolt has not yet locked the positioning plate, the positioning plate can move. The first spring connects the positioning plate and the fixed seat, making it convenient for the operator to change the vertical distance between the positioning plate and the fixed seat, and control the stretching of the first spring to increase the space so that the wing nut can be better inserted into the positioning groove.

[0013] Preferably, the mounting plate is provided with a plurality of fixing seats, each of which is spaced apart along the length of the mounting plate, and each fixing seat is used to fix the wing nut.

[0014] By adopting the above technical solution, multiple fixing seats are used to fix multiple wing nuts, thereby improving the space utilization of the mounting plate.

[0015] Preferably, a limiting post is connected to the side of the pressure block away from the fixed base, and the limiting post is used to prevent the pressure block from completely passing through the limiting hole.

[0016] By adopting the above technical solution, when the linear cylinder controls the lifting block to move down, the surface area of ​​the pressure block pressed against the side plate will gradually decrease until it reaches zero. The limit post can prevent the pressure block from completely leaving the limit hole, reducing unnecessary trouble.

[0017] Preferably, the clamping component is a lifting cylinder, which is mounted on the fixed base. The lifting cylinder is connected to the positioning plate via a rotating component, which controls the rotation of the positioning plate, and the lifting cylinder controls the lifting of the positioning plate.

[0018] By adopting the above technical solution, the lifting cylinder can control the vertical movement of the positioning plate, and the wing nut is fixed by the force of the cylinder. The lifting cylinder replaces the fastening bolts to tighten the positioning plate, improving convenience.

[0019] Preferably, it further includes a pushing assembly for pushing the processed wing nut out of the positioning groove; the pushing assembly includes a wedge block, a push rod, and a second spring; the rotating component is a rotary motor, which is mounted on the piston rod of the lifting cylinder and connected to the positioning pressure plate; the wedge block is movably connected to the fixed base, and the fixed base has a sliding groove for the wedge block to move; the wedge surface of the wedge block is within the rotation radius of the positioning pressure plate. The push rod is horizontally positioned, with one end connected to the wedge block and the other end used to push out the processed wing nut. The fixed seat has a limiting groove for accommodating the push rod. The two ends of the second spring are connected to the fixed seat and the wedge block respectively. When the positioning plate rotates and pushes the wedge block to move, the second spring is pushed and compressed by the wedge block.

[0020] By adopting the above technical solution, after the wing nut has completed two processing steps, it needs to be unloaded. The traditional method is to manually loosen the fastening bolts first to release the pressure of the positioning plate on the wing nut, and then remove the wing nuts in the positioning groove one by one. This method is inefficient.

[0021] By replacing the fastening bolts with a lifting cylinder, after the wing nut is processed, the lifting cylinder controls the rotary motor and the positioning plate to rise vertically synchronously, at which point the positioning plate releases its pressure on the wing nut. Then, the rotary motor controls the positioning plate to rotate. As the positioning plate moves in a circular trajectory, the wedge block, positioned on the rotation path of the positioning plate, pushes the wedge block to move and compresses the second spring. The push rod follows and presses against the side plate. Due to the pushing force of the push rod, the wing nut is unloaded. After the positioning plate rotates one revolution and returns to its original position, the accumulated elastic potential energy of the second spring controls the wedge block to reset.

[0022] Preferably, the fixed base has two symmetrically arranged positioning grooves, and the positioning pressure plate is used to simultaneously press the wing nuts in the two positioning grooves. The side pressure assembly is provided in two sets accordingly. It also includes a triangular push block and a connecting rope. The triangular push block is rotatably connected to the fixed base through a torsion spring. The two ends of the connecting rope are respectively connected to the triangular push block and the wedge block. When the positioning pressure plate pushes the wedge block to compress the second spring, the connecting rope pulls the triangular push block to rotate, and the triangular push block is used to push out another wing nut.

[0023] By adopting the above technical solution, the two positioning slots correspond to the two wing nuts respectively, and a positioning pressure plate presses on the two wing nuts at the same time, while the two side pressure components press on the two wing nuts respectively.

[0024] After the wing nuts have completed two processing steps, the rotary motor controls the positioning plate to rotate. When the positioning plate rotates and pushes the second spring of the wedge block, the movement of the push rod can push out one of the wing nuts. At the same time, the connecting rope on the wedge block can pull the triangular push block to rotate, so that one end of the triangular push block pushes out the other wing nut, thus realizing the unloading of two wing nuts.

[0025] Preferably, the lathe further includes a lathe body, a base, a rotary table, and a machining head. The lathe body has a machining cavity, the base is located in the machining cavity, the rotary table is rotatably connected to the base, and the mounting plate is detachably connected to the rotary table. The machining head is raised and lowered on the lathe body and is located above the support base for machining wing nuts.

[0026] By adopting the above technical solution, before processing, the mounting plate is first horizontally installed on the rotary table, and then the wing nut is fixed to the fixed seat. Then, the base is controlled to move within the lathe body according to a preset program trajectory, while the machining head is controlled to move vertically downwards and extend into the through hole of the cylindrical part to perform internal thread processing. After the internal thread is processed, the side pressure assembly is removed from the side plate, and then the rotary table is controlled to rotate at a certain angle so that the side plate is directly facing the machining head, allowing the machining head to complete the processing of the side plate.

[0027] Preferably, the mounting plate has a slot at one end, a locking block is connected to the rotating disk, the locking block is engaged in the slot, the mounting plate has a mounting hole for bolts to pass through, and the mounting plate is locked onto the rotating disk by bolts; there are two rotating disks arranged opposite each other, and the two ends of the mounting plate are respectively connected to the two rotating disks.

[0028] By adopting the above technical solution, during installation, the card block is first inserted into the card slot, and then the mounting plate is locked onto the rotating disk with bolts, thus realizing the detachable connection of the mounting plate.

[0029] Secondly, this application also provides a method for processing wing nuts, which uses a processing device with all the above-described structures to process wing nuts, including the following steps: S1. The worker first places the wing nut to be processed into the positioning groove, then uses the lifting cylinder to control the positioning plate to press it on the cylindrical part, and at the same time uses the side pressing component to press it on the side part to complete the fixing of the wing nut. S2. Next, control the base to move along the X and Y axes to adjust the relative position of the base to the machining head; then control the machining head to move down along the Z axis to approach the wing nut, and the machining head passes through the clearance hole to perform internal thread machining on the through hole of the cylindrical part. S3. After the internal thread is machined, remove the side pressure assembly from the side part, then control the rotating disk to rotate at a certain angle so that the side part faces the machining head, and then use the machining head to machine the outer surface of the side part. S4. After the side processing is completed, the lifting cylinder controls the positioning plate to move up a certain distance, the rotary motor controls the positioning plate to rotate in a circle, the positioning plate pushes the wedge block to squeeze the second spring, so that the push rod pushes out the wing nut in the positioning groove to realize the unloading.

[0030] In summary, this application includes at least one of the following beneficial technical effects: (1) By setting up clamping parts, positioning pressure plates and side pressure components, the positioning pressure plates and side pressure components are respectively pressed on the cylindrical part and the side plate part, which improves the stability of the wing nut processing and ensures the product processing quality.

[0031] (2) By setting up a pusher assembly, the pusher assembly can unload the wing nuts after processing, reducing the labor intensity of personnel. Attached Figure Description

[0038] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0039] Example 1 This application discloses a device for processing wing nuts. (Refer to...) Figure 2 and Figure 3 The processing device includes a mounting plate 1, a fixed base 2, a clamping component 3, a positioning pressure plate 4, and a side pressure assembly 5. The mounting plate 1 is rectangular, and both ends are fixed to a machine tool. The fixed base 2 is fixed to one side surface of the mounting plate 1, and a positioning groove 6 is provided on the fixed base 2 for positioning the wing nut. The positioning pressure plate 4 is locked to the fixed base 2 by the clamping component 3. In this embodiment, the clamping component 3 is a fastening bolt, which passes through the positioning pressure plate 4 and is screwed onto the fixed base 2. The positioning pressure plate 4 is used to press the cylindrical part of the wing nut, and a clearance hole 7 communicating with a through hole is provided on the positioning pressure plate 4.

[0040] The side-pressing assembly 5 is mounted on the mounting plate 1 and is used to press the side plate portion of the wing nut. The side-pressing assembly 5 includes a linear cylinder 51, a lifting block 52, and a pressing block 53. The linear cylinder 51 is located on the other side of the mounting plate 1, and the lifting block 52 is movably mounted on the mounting plate 1 and connected to the piston rod of the linear cylinder 51. A limiting hole 8 is provided through the mounting plate 1. The pressing block 53 and the lifting block 52 are integrally connected, and the limiting hole 8 is used for the pressing block 53 to pass through. Among them, a limiting post 9 is fixedly connected to the side of the pressing block 53 away from the fixed base 2, and the limiting post 9 is used to prevent the pressing block 53 from completely passing through the limiting hole 8.

[0041] Before processing, the operator first clamps the wing nut into the positioning groove 6, and then uses the clamping component 3 to press the positioning plate 4 onto the fixed seat 2. Next, the linear cylinder 51 is operated to control the lifting block 52 to move upward, thereby driving the pressure block 53 to move upward and press the side plate onto the fixed seat 2, thus completing the fixing of the wing nut. During processing, the wing nut is clamped by the positioning plate 4 and the side pressure component 5, which improves the stability of the wing nut during processing and reduces the possibility of shaking.

[0042] Specifically, a first spring 10 is also connected to the fixed base 2. The two ends of the first spring 10 are connected to the positioning plate 4 and the fixed base 2, respectively. The fastening bolt passes through the first spring 10, and the direction of the spring force of the first spring 10 is parallel to the lifting direction of the lifting block 52. When the fastening bolt has not yet locked the positioning plate 4, the positioning plate 4 can move. The first spring 10 connects the positioning plate 4 and the fixed base 2, allowing workers to easily change the vertical distance between the positioning plate 4 and the fixed base 2, and control the stretching of the first spring 10 to increase space so that the wing nut can better engage in the positioning groove 6. Several fixed bases 2 are provided on the mounting base, spaced apart along the length of the mounting plate 1. Each fixed base 2 is used to fix the wing nut, improving the space utilization and production efficiency of the mounting plate 1.

[0043] Combination Figure 4 and Figure 5 In addition, in this embodiment, the processing device also includes a lathe body 11, a base 12, a rotary disk 13, and a processing head 14. The lathe body 11 is placed on the ground and has a processing cavity. The base 12 is located inside the processing cavity and can move along the X and Y axes. The rotary disk 13 is rotatably connected to the base 12 via a servo motor, and the mounting plate 1 is detachably connected to the rotary disk 13. The end of the mounting plate 1 has a slot 15, and a locking block 16 is fixedly connected to the rotary disk 13, engaging within the slot 15. The mounting plate 1 also has multiple mounting holes 17 through it for bolts to pass through, and the mounting plate 1 is locked to the rotary disk 13 by bolts. There are two horizontally opposite rotary disks 13, and the two ends of the mounting plate 1 are connected to the two rotary disks 13 respectively.

[0044] Before production, the mounting plate 1 is first horizontally installed on the rotary table 13, and then the wing nut is fixed to the fixed base 2. Then, the base 12 is controlled to move within the lathe body 11 according to a preset program trajectory, while the machining head 14 is controlled to move vertically downwards and extend into the through hole of the cylindrical part to perform internal thread machining. After the internal thread is machined, the side pressure assembly 5 is removed from the side plate, and then the rotary table 13 is controlled to rotate at a certain angle so that the side plate is directly facing the machining head 14, allowing the machining head 14 to complete the machining of the side plate.

[0045] The implementation principle of the wing nut processing device in this application embodiment is as follows: During production, the operator first uses bolts to lock both ends of the mounting plate 1 onto the rotating disk 13. Then, the wing nut is snapped into the positioning groove 6, and then the positioning pressure plate 4 is locked onto the fixed seat 2 using fastening bolts. At the same time, the linear cylinder 51 is operated to control the lifting block 52 to move upward, thereby driving the pressure block 53 to move upward and pressing the side plate onto the fixed seat 2, thus completing the fixing of the wing nut.

[0046] Then, the base 12 is controlled to move within the lathe body 11 according to a preset program trajectory, while the machining head 14 is controlled to move vertically downward and extend into the through hole of the cylindrical part to perform internal thread machining. After the internal thread is machined, the side pressure assembly 5 is removed from the side plate, and then the rotary table 13 is controlled to rotate at a certain angle so that the side plate is facing the machining head 14 for machining of the side plate.

[0047] Example 2 Please refer to Figure 6 and Figure 7 The difference between Embodiment 2 and Embodiment 1 lies in the clamping component 3. In this embodiment, the clamping component 3 is a lifting cylinder, which is connected to the positioning plate 4 via a rotating component 18. The lifting cylinder is used to control the up and down movement of the positioning plate 4. The rotating component 18 is a rotary motor, used to control the rotation of the positioning plate 4, and the rotation axis of the positioning plate 4 is in the vertical direction. A pushing assembly 19 is installed on the fixed base 2, which is used to push the processed wing nut out of the positioning groove 6.

[0048] The pusher assembly 19 includes a wedge block 191, a push rod 192, and a second spring 193. A rotary motor is connected to the piston rod of a lifting cylinder, and the output shaft of the rotary motor is connected to a positioning pressure plate 4. The wedge block 191 is movably connected to a fixed base 2. The fixed base 2 has a groove 20 for the wedge block 191 to move. The wedge block 191 moves horizontally, and its wedge-shaped surface is within the rotation radius of the positioning pressure plate 4. The push rod 192 is horizontally positioned. One end of the push rod 192 is fixedly connected to the wedge block 191, and the other end passes through the fixed base 2. The fixed base 2 has a limiting groove for the push rod 192 to accommodate and move. The push rod 192 is used to push out the processed wing nut. The two ends of the second spring 193 are respectively fixed to the base 2 and the wedge block 191. When the positioning plate 4 rotates and pushes the wedge block 191 to move, the second spring 193 is pushed and compressed by the wedge block 191. At this time, the push rod 192 extends out of the fixed base 2 and pushes down the wing nut.

[0049] After the wing nuts have undergone two processing steps, they need to be unloaded. At this time, the side pressure component 5 is not pressing the wing nuts tightly; only the positioning pressure plate 4 is still exerting pressure on the wing nuts. The traditional method is to manually loosen the fastening bolts to release the pressure of the positioning pressure plate 4 on the wing nuts, and then remove the wing nuts from the positioning groove 6 one by one. This method is inefficient.

[0050] In this embodiment, the fastening bolts are replaced with a lifting cylinder. After the wing nut is processed, the lifting cylinder controls the rotary motor and the positioning plate 4 to rise vertically synchronously. At this time, the positioning plate 4 releases its pressure on the wing nut. Then, the rotary motor controls the positioning plate 4 to rotate. When the positioning plate 4 moves in a circular trajectory, since the wedge block 191 is on the rotation path of the positioning plate 4, the end of the positioning plate 4 pushes the wedge block 191 to move and compress the second spring 193. The push rod 192 moves along with it and presses against the side plate. Due to the pushing force of the push rod 192, the wing nut is automatically unloaded. When the positioning plate 4 rotates one revolution and returns to its original position, the elastic potential energy accumulated by the second spring 193 can control the wedge block 191 to reset.

[0051] In this embodiment, two symmetrical positioning grooves 6 are provided on the fixed base 2, and the positioning pressure plate 4 is used to simultaneously press the wing nuts in the two positioning grooves 6; two sets of side pressure components 5 are provided accordingly, and the two side pressure components 5 are respectively pressed on the two wing nuts. Two sets of pusher components 19 are also provided symmetrically, and the two pusher components 19 are used to push down the two wing nuts. A triangular pusher block 21 and a connecting rope 22 are also connected to the fixed base 2. The triangular pusher block 21 is rotatably connected to the fixed base 2 by a torsion spring. The upper end of the triangular pusher block 21 is lower than the upper end of the wedge block 191, that is, the positioning pressure plate 4 can only touch the wedge block 191 during rotation, but will not touch the triangular pusher block 21. The connecting rope 22 is located between the wedge block 191 and the triangular block. The two ends of the connecting rope 22 are connected to the triangular push block 21 and the wedge block 191 respectively. The movement of the wedge block 191 can drive the triangular push block 21 to rotate. The triangular push block 21 and the push rod 192 are used to push out the wing nuts in the two positioning grooves 6 respectively.

[0052] After the wing nut completes two processing steps, the rotary motor controls the positioning plate 4 to rotate. When the positioning plate 4 rotates and pushes the second spring 193 of the wedge block 191, the movement of the push rod 192 can push out one of the wing nuts. At the same time, the connecting rope 22 on the wedge block 191 can pull the triangular push block 21 to rotate, so that one end of the triangular push block 21 pushes out the other wing nut, realizing the unloading of two wing nuts and improving efficiency.

[0053] Based on the above embodiments, this application also provides a method for processing wing nuts, which uses a processing device with all the above structures to process wing nuts, including the following steps: S1. The worker first places the wing nut to be processed into the positioning groove 6, then uses the lifting cylinder to control the positioning plate 4 to press it on the cylindrical part, and at the same time uses the linear cylinder 51 to control the pressure block 53 to move and press it on the side part, thus completing the fixing of the wing nut. S2. Next, control the base 12 to move along the X-axis and Y-axis directions to adjust the relative position of the base 12 with respect to the machining head 14; then control the machining head 14 to move down along the Z-axis direction to approach the wing nut, and the machining head 14 passes through the clearance hole 7 to perform internal thread machining on the through hole of the cylindrical part. S3. After the internal thread is machined, remove the clamping effect of the side pressure component 5 on the side part, and then control the rotating disk 13 to rotate a certain angle (ninety degrees) so that the side part faces the machining head 14. Then use the machining head 14 to machine the outer surface of the side part. S4. After the side processing is completed, the lifting cylinder controls the positioning plate 4 to move up a certain distance, and the rotary motor controls the positioning plate 4 to rotate in a circle. During the rotation, the positioning plate 4 pushes the wedge block 191 to squeeze the second spring 193, so that the push rod 192 pushes out the wing nut in the positioning groove 6, realizing automatic unloading and reducing the labor intensity of personnel.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
