Description

Technical Field

[0001] This invention relates to the field of nut processing equipment technology, specifically to a composite processing equipment for opening and chamfering carbon steel nuts for photovoltaic fastening. Background Technology

[0002] In the field of photovoltaic fastening, carbon steel nuts are key mechanical connectors, and their processing precision and quality directly affect the installation stability and service life of photovoltaic modules.

[0003] Currently, the manufacturing process of carbon steel nuts requires three core steps: drilling, tapping the threaded bottom hole, and chamfering the end of the threaded hole. However, the existing processing mode has significant technical bottlenecks: First, the drilling, tapping, and chamfering processes are scattered across different processing equipment or stations, requiring the workpiece to be clamped and positioned multiple times and the equipment parameters to be adjusted frequently. This not only prolongs the production cycle but also easily accumulates clamping errors. Second, traditional chamfering equipment can only process the chamfer at the end of the threaded hole one side at a time. After each processing, the nut needs to be manually disassembled, flipped, and re-clamped. This step-by-step operation not only significantly reduces the processing efficiency of the chamfering process but also easily causes positioning deviations during repeated clamping. Therefore, a composite processing equipment for drilling and chamfering carbon steel nuts for photovoltaic fastening is proposed. This equipment facilitates drilling, tapping, and chamfering of the nut to achieve continuous processing of multiple processes, effectively shortening the process flow, improving processing efficiency, and enhancing product quality stability. Summary of the Invention

The spindle boxes are slidably installed below the electric slide rail through the slide blocks. Positioning cylinders corresponding to integrated drilling and chamfering tools and tapping and chamfering tools are respectively provided on both sides of the rotating ring.

[0006] Specifically, the fixed ring has a fan-shaped channel inside that communicates with the inside of the fixed cylinder, and each slot has a through hole that communicates with the inner ring of the rotating ring; both ends of the fixed cylinder are fixedly connected to support legs, and one end of the fixed cylinder is fixedly connected to a negative pressure pump that communicates with the inside of the fixed cylinder; both sides of the fixed ring are fixedly connected to an upward-opening material collection frame, the lower end of which communicates with the inside of the fixed cylinder, and the material collection frame is located below the positioning cylinder.

[0007] Specifically, the upper part of the positioning cylinder is fixedly connected to the lower surface of the electric slide rail via a support rod, and the lower part of the positioning cylinder is provided with an arc-shaped discharge chute, which corresponds to the upper part of the collection frame.

[0008] Specifically, a dual-axis motor is fixedly connected to one side of the outrigger, and a gear is fixedly connected to one end of the dual-axis motor. The outer side of the rotating ring is provided with teeth that are circumferentially distributed and mesh with the gear for transmission.

[0009] Specifically, a discharge port is opened at the lower part of the fixed cylinder away from the negative pressure pump, and the discharge port can be detachably connected to the silo door; a horizontally arranged spiral feeding shaft is rotatably connected inside the fixed cylinder, one end of the spiral feeding shaft passes through the fixed cylinder and is rotatably connected to the fixed cylinder, and a first pulley is fixedly connected to one end of the spiral feeding shaft; a second pulley is fixedly connected to the end of the dual-shaft motor away from the gear, and the first pulley and the second pulley are driven by a transmission belt.

[0010] Specifically, the electric slide rail is fixedly connected to the outside of the support leg through several sets of support members; a horizontally arranged top material rod is provided on one side of the rotating ring, and the top material rod and the fan-shaped channel of the fixed ring are intersected. The end of the top material rod away from the rotating ring is fixedly connected to one side of a set of spindle boxes through the first connector.

[0011] Specifically, a storage frame corresponding to the top material rod is provided on the side of the rotating ring away from the top material rod.

[0013] Specifically, there are several sets of reinforcing components that are fixedly connected between the two sets of outriggers.

[0014] The beneficial effects of this invention are:

[0015] The present invention discloses a composite processing equipment for drilling and chamfering carbon steel nuts for photovoltaic fastening. By using a rotating ring, an electric slide rail, and a spindle box that installs both drilling and chamfering tools, the three core processes of drilling, tapping, and double-sided chamfering are integrated into the same equipment. This avoids the transfer of workpieces between different equipment and multiple clamping, shortens the production cycle, and improves production efficiency and product quality.

[0016] The present invention discloses a composite processing equipment for opening and chamfering carbon steel nuts for photovoltaic fastening. The through grooves distributed around the circumference of the rotating ring can simultaneously position multiple nuts. By rotating, the nuts are sequentially transported to different processing stations, avoiding the frequent handling of workpieces and adjustment of equipment parameters in the traditional single-machine single-process mode.

[0017] The present invention discloses a composite processing equipment for opening and chamfering carbon steel nuts for photovoltaic fastening. The shape of the through groove on the rotating ring matches the outer contour of the nut, restricting the circumferential movement of the nut and ensuring no shaking during processing. The fixed cylinder is connected to the through hole through a fan-shaped channel. The negative pressure pump creates a negative pressure environment in the fixed cylinder, adsorbing the nut through the through hole and preventing the nut from falling off when the rotating ring rotates.

[0018] The present invention discloses a composite processing equipment for opening and chamfering carbon steel nuts for photovoltaic fastening. After the processing waste is collected by the collection frame below the positioning cylinder, the negative pressure environment inside the fixed cylinder accelerates the suction of waste such as metal shavings and dust into the fixed cylinder, avoiding the accumulation of waste below the positioning cylinder or near the rotating ring groove, and effectively eliminating the impact of waste on processing accuracy. When the rotating ring completes one station rotation and the processing cycle of a single nut ends, the spiral feeding shaft synchronously completes one full rotation, pushing the waste from the end away from the negative pressure pump in the fixed cylinder towards the discharge port, ensuring that the waste is effectively transported to the vicinity of the discharge port, so that waste treatment and processing are completely synchronized, avoiding resource waste, realizing processing and discharge at the same time, and significantly improving production efficiency.

[0019] The present invention discloses a composite processing equipment for drilling and chamfering carbon steel nuts for photovoltaic fastening. After the nut has been drilled, tapped, and chamfered on both sides, the ejector rod moves synchronously with the spindle box, directly ejecting the processed nut from the rotating groove without manual removal, thus eliminating the need for manual operation. During the ejection process, the ejector rod can simultaneously remove residual metal debris in the groove, preventing debris accumulation from affecting the positioning and placement of the next set of nuts, ensuring the cleanliness of the rotating groove and the accuracy of subsequent processing.

Detailed Implementation

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] To facilitate drilling, tapping, and chamfering of nuts, enabling continuous multi-process machining, effectively shortening the process flow, improving processing efficiency, and enhancing product quality stability, as one embodiment of the present invention, such as... Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the photovoltaic fastening carbon steel nut drilling and chamfering composite processing equipment of the present invention includes a horizontally arranged fixed cylinder 1, a fixed ring 2 fixedly connected to the outside of the fixed cylinder 1, and a rotating ring 3 rotatably connected to the outside of the fixed ring 2. Several sets of through grooves 4 for positioning nuts are distributed circumferentially on the rotating ring 3. A horizontally arranged electric slide rail 5 is provided above the rotating ring 3. Two sets of slide seats 6 are slidably connected to the lower surface of the electric slide rail 5. A spindle box 7 for installing a drill-and-chamfer integrated tool and a spindle box 7 for installing a tapping and chamfering tool are respectively provided on both sides of the rotating ring 3. The spindle boxes 7 are slidably installed below the electric slide rail 5 through the slide seats 6. Positioning cylinders 9 corresponding to the drill-and-chamfer integrated tool and the tapping and chamfering tool are respectively provided on both sides of the rotating ring 3.

[0032] When in use, the carbon steel nuts to be processed are placed one by one into the through groove 4 of the swivel 3 to ensure that the nuts are fully embedded in the through groove 4. The through groove 4 restricts the circumferential movement of the nuts, achieves initial positioning, and prevents the nuts from shaking during processing.

[0033] The drive ring 3 rotates around the outside of the fixed ring 2, and the nut moves synchronously with the ring 3. When the ring 3 moves the nut to the side of the positioning cylinder 9, the ring 3 stops. The electric slide rail 5 is started, driving one side slide 6 and the spindle box 7 with the drill-and-chamfer tool installed to move toward the nut. The other side slide 6 and the spindle box 7 with the tapping and chamfering tool installed move away from the nut synchronously. The drill-and-chamfer tool moves horizontally with the spindle box 7, passes through the positioning cylinder 9 and contacts the side of the nut. Drilling is completed first, and then the edge of the hole is chamfered. During the processing, the other side positioning cylinder 9 always supports the nut. When the spindle box 7 moves to the preset stroke end point, drilling and single-sided chamfering are completed.

[0034] Then, the electric slide rail 5 is driven to work in reverse, which drives the spindle box 7, which is equipped with the integrated drill and chamfer cutter, to reset and move away from the nut. At the same time, the slide 6 on the other side and the spindle box 7 move toward the nut. After the tapping and chamfering cutter moves to a certain position with the spindle box 7, it passes through the positioning cylinder 9 and contacts the end face of the nut that has been drilled, completing the tapping of the thread bottom hole. After the tapping is completed, the edge of the other end of the thread hole is chamfered to achieve double-sided chamfering. After the spindle box 7 equipped with the tapping and chamfering cutter reaches the preset stroke end point, the tapping and chamfering process is completed.

[0035] After a set of nuts has been drilled, tapped, and chamfered on both sides, the slide block 6 is moved by the electric slide rail 5, so that the spindle box 7 of the tapping and chamfering tool is reset away from the rotating ring 3 along with the slide block 6 and exits the processing area. After the slide block 6 is reset, when the rotating ring 3 rotates, the processed nuts leave the processing area along with the through groove 4. The next set of nuts to be processed moves synchronously to the side of the positioning cylinder 9. The axis of the nut is aligned with the axis of the drill-and-chamfer tool and the tapping and chamfering tool, so as to facilitate the drilling, tapping and chamfering of the nuts, so as to realize multi-process continuous processing, effectively shorten the process flow, improve processing efficiency and product quality stability.

[0036] To enhance the stability of the nut within the through groove 4, for example, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the present invention also includes: a fan-shaped channel 10 communicating with the inside of the fixed ring 2 and a through hole 11 communicating with the inner ring of the rotating ring 3 in each of the through grooves 4; support legs 12 are fixedly connected to the outer sides of both ends of the fixed ring 1 and a negative pressure pump 13 communicating with the inside of the fixed ring 1 is fixedly connected to one end of the fixed ring 1; and material collection frames 14 with upward openings are fixedly connected to both sides of the fixed ring 2, the lower end of the material collection frame 14 communicating with the inside of the fixed ring 1 and the material collection frame 14 being located below the positioning cylinder 9.

[0037] In use, when the through hole 11, the fan-shaped channel 10 and the inside of the fixed cylinder 1 form a communication path, the negative pressure pump 13 connected to one end of the fixed cylinder 1 runs continuously, creating a negative pressure environment inside the fixed cylinder 1. The negative pressure is conducted to the through hole 11 through the fan-shaped channel 10, causing the through hole 11 to generate an adsorption force, which embeds the nut to be processed into the through groove 4 that has been connected to the fan-shaped channel 10 through the through hole 11 to complete the positioning, enhancing the stability of the nut in the through groove 4, thereby preventing the nut from falling out of the through groove 4 when the rotating ring 3 rotates;

[0038] Waste materials such as metal shavings generated during processing are collected through the collection frame 14 below the positioning cylinder 9 and enter the fixed cylinder 1 through the lower end of the collection frame 14. This allows for direct collection of processing waste, preventing it from scattering outside the equipment and maintaining a clean processing environment. At the same time, negative pressure creates suction within the collection frame 14, which quickly draws metal shavings, dust, and other waste materials into the fixed cylinder 1 through the opening of the collection frame 14. This prevents waste materials from accumulating below the positioning cylinder 9 or near the through groove 4. For thin, light shavings generated by chamfering, negative pressure adsorption can compensate for the shortcomings of relying solely on gravity, ensuring that all types of waste materials can be collected efficiently.

[0039] To facilitate the collection of waste materials from the processing, for example, such as Figure 1 , Figure 4 As shown, the present invention also includes a positioning cylinder 9 whose upper part is fixedly connected to the lower surface of the electric slide rail 5 via a support rod 15, and an arc-shaped discharge groove 16 provided at the lower part of the positioning cylinder 9, which corresponds to the upper part of the collecting frame 14.

[0040] In use, the positioning cylinder 9 is rigidly connected to the electric slide rail 5 through the support rod 15. When the rotating ring 3 drives the nut to move to the side of the positioning cylinder 9, the positioning cylinder 9 can limit the radial movement range of the nut and prevent the nut from coming off from the side when drilling or tapping.

[0041] Waste materials such as metal shavings generated during the processing, such as drilling, tapping, and chamfering, fall through the gap between the positioning cylinder 9 and the nut into the arc-shaped discharge groove 16 at the bottom of the positioning cylinder 9, and directly into the opening of the aligned collection frame 14 below, realizing the directional transmission of waste materials. There is no need for manual cleaning of the positioning cylinder 9 area, which meets the needs of continuous processing.

[0042] For example, to facilitate the rotation of the rotating ring 3, such as... Figure 3 , Figure 6 As shown, the present invention also includes a dual-axis motor 17 fixedly connected to one side of the support leg 12, a gear 18 fixedly connected to one end of the dual-axis motor 17, and teeth 19 distributed circumferentially on the outer side of the rotating ring 3 to mesh with the gear 18 for transmission.

[0043] In use, the carbon steel nuts to be processed are placed one by one into the through groove 4 of the rotating ring 3, ensuring that the nuts are fully embedded in the through groove 4. After the dual-axis motor 17 is powered on, the output shaft drives the gear 18 to rotate. The gear 18 drives the rotating ring 3 to make a circular motion around the outside of the fixed ring 2 through the meshing of the teeth 19. This causes the through groove 4 on the rotating ring 3 to transport the nuts to be processed to the processing station on the side of the positioning cylinder 9 in sequence. During the rotation of the rotating ring 3, a single nut passes through the drilling and chamfering tool station and the tapping and chamfering tool station along with the through groove 4, realizing multi-process continuous processing.

[0044] For example, such as Figure 1 , Figure 3 , Figure 6 , Figure 7 As shown, the present invention also includes a discharge port at the lower part of the fixed cylinder 1 away from the negative pressure pump 13, the discharge port being detachably connected to the hopper door 20; a horizontally arranged spiral feeding shaft 21 is rotatably connected inside the fixed cylinder 1, one end of the spiral feeding shaft 21 passes through the fixed cylinder 1 and is rotatably connected to the fixed cylinder 1, and a first pulley 22 is fixedly connected to one end of the spiral feeding shaft 21; a second pulley 23 is fixedly connected to the end of the dual-shaft motor 17 away from the gear 18, and the first pulley 22 and the second pulley 23 are driven by a transmission belt 24.

[0045] During use, metal shavings, dust, and other waste generated during processing fall into the fixed cylinder 1 through the collection frame 14. Under the action of the negative pressure pump 13, they converge into the fixed cylinder 1. After the dual-shaft motor 17 starts, it drives the transmission belt 24 to rotate through the second pulley 23 at the other end, which drives the first pulley 22 and the coaxial spiral feeding shaft 21 to rotate synchronously. This pushes the waste from the end of the fixed cylinder 1 away from the negative pressure pump 13 towards the discharge port, realizing the directional movement of the waste. When the waste accumulates to a set amount near the discharge port, the operation of the dual-shaft motor 17 is stopped, and the hopper door 20 at the discharge port is removed to discharge the waste from the discharge port.

[0046] To facilitate the removal of the processed nuts, for example, such as... Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the present invention also includes an electric slide rail 5 fixedly connected to the outside of the support leg 12 via several sets of support members 25; a horizontally arranged top material rod 26 is provided on one side of the rotating ring 3, the top material rod 26 intersects with the fan-shaped channel 10 of the fixed ring 2, and the end of the top material rod 26 away from the rotating ring 3 is fixedly connected to one side of a set of spindle boxes 7 via a first connector 27.

[0047] In use, after a set of nuts has been drilled, tapped and chamfered on both sides, the electric slide rail 5 drives the spindle box 7, which is equipped with tapping and chamfering tools, to move away from the rotating ring 3 along with the slide 6 and exit the processing area. After the slide 6 is reset, the dual-axis motor 17 drives the rotating ring 3 to rotate through the gear 18. The processed nuts leave the processing area along with the through groove 4. The next set of nuts to be processed moves synchronously to the side of the positioning cylinder 9. When the rotating ring 3 rotates to the point where the through groove 4 of the processed nuts intersects with the fan-shaped channel 10 of the fixed ring 2, the through groove 4 is no longer connected to the through hole 11 and no longer has an adsorption effect on the nuts. The electric slide rail 5 drives the slide 6 to move the drill and chamfering integrated tool spindle box 7 towards the rotating ring 3. When drilling and chamfering the next set of nuts, the top rod 26 fixed on one side of the spindle box 7 advances synchronously, squeezing the processed nuts and causing the nuts to detach from the through groove 4. This realizes the full automation of nut processing and unloading.

[0048] The support member 25 can ensure the overall stability of the electric slide rail 5; the first connecting member 27 can ensure the stability of the top material rod 26 when it moves.

[0049] For example, such as Figure 2 , Figure 3 As shown, the present invention also includes a storage frame 28 corresponding to the top material rod 26 on the side of the rotating ring 3 away from the top material rod 26, a feed inlet 29 on the upper surface of the storage frame 28, and one side of the storage frame 28 being fixedly connected to one side of the support member 25 through the second connector 30.

[0050] When in use, when the ejector rod 26 is pushed forward synchronously with the spindle box 7, it can push out the nuts that have been drilled, tapped and chamfered on both sides in the through groove 4 of the rotating ring 3. The nuts are pushed by the ejector rod 26 and move to the side of the rotating ring 3 away from the ejector rod 26, and fall into the storage frame 28. The processed nuts are collected through the storage frame 28.

[0051] The second connector 30 ensures the overall stability of the storage frame 28.

[0052] For example, such as Figure 1 , Figure 4 As shown, the present invention also includes a drill-chamfer integrated tool comprising a drill bit 31 and a first chamfering head 32, wherein the drill bit 31 and the first chamfering head 32 are coaxially arranged and fixedly connected; and a tapping and chamfering tool comprising a tap 33 and a second chamfering head 34, wherein the tap 33 and the second chamfering head 34 are coaxially arranged and fixedly connected.

[0053] In use, in the drill-and-chamfer integrated tool, the drill bit 31 and the first chamfering head 32 are coaxially fixed to ensure that after drilling is completed, the first chamfering head 32 can directly chamfer the edge of the hole without readjusting the tool axis, avoiding positioning errors caused by secondary tool setting, and ensuring the coaxiality of the hole and the chamfer.

[0054] In the tapping and chamfering tool, the tap 33 and the second chamfering head 34 are fixed coaxially. After tapping is completed, the other end of the threaded hole is immediately chamfered to ensure that the thread axis is strictly aligned with the chamfer edge, thereby improving the flatness and perpendicularity of the end of the threaded hole.

[0055] For example, such as Figure 1 As shown, the present invention also includes a plurality of reinforcing members 8 fixedly connected between the two sets of support legs 12.

[0056] When in use, the reinforcement 8 can enhance the overall rigidity of the equipment, reduce vibration and deformation, and improve its impact resistance.

[0057] When using this invention, the carbon steel nuts to be processed are placed one by one into the through groove 4 of the rotating ring 3 to ensure that the nuts are fully embedded in the through groove 4. The through groove 4 restricts the circumferential movement of the nuts, achieving initial positioning and preventing the nuts from shaking during processing. The negative pressure pump 13 is started, and the nuts are adsorbed through the negative pressure environment inside the fixed cylinder 1, the fan-shaped channel 10 and the through hole 11, to enhance the positioning stability.

[0058] Start the dual-axis motor 17, which drives the rotating ring 3 to rotate through the meshing of gear 18 and teeth 19. The nut moves synchronously with the rotating ring 3. When the rotating ring 3 moves the nut to the side of the positioning cylinder 9, the rotating ring 3 stops. Start the electric slide rail 5, which drives one side slide 6 and the spindle box 7 with the drill-and-chamfer tool installed to move toward the nut. The other side slide 6 and the spindle box 7 with the tapping and chamfering tool installed move away from the nut synchronously. The drill-and-chamfer tool moves horizontally with the spindle box 7, passes through the positioning cylinder 9 and contacts the side of the nut. The drill bit 31 first completes the drilling, and then the first chamfering head 32 chamfers the edge of the hole. During the processing, the positioning cylinder 9 on the other side always supports the nut. When the spindle box 7 moves to the preset end point of the stroke, the drilling and single-sided chamfering are completed.

[0059] Then, the electric slide rail 5 is driven to work in reverse, which drives the spindle box 7, which is equipped with the integrated drill and chamfer cutter, to reset and move away from the nut. At the same time, the slide 6 on the other side and the spindle box 7 move toward the nut. After the tapping and chamfering cutter moves to a certain position with the spindle box 7, it passes through the positioning cylinder 9 and contacts the end face of the nut that has been drilled. The tap 33 is used to complete the tapping of the thread bottom hole. After the tapping is completed, the second chamfering cutter head 34 is used to chamfer the edge of the other end of the thread hole to achieve double-sided chamfering. After the spindle box 7 equipped with the tapping and chamfering cutter reaches the preset stroke end point, the tapping and chamfering process is completed.

[0060] After a set of nuts has been drilled, tapped, and chamfered on both sides, the slide block 6 is moved by the electric slide rail 5, so that the spindle box 7 of the tapping and chamfering tool is reset away from the rotating ring 3 along with the slide block 6 and exits the processing area. After the slide block 6 is reset, when the rotating ring 3 rotates, the processed nuts leave the processing area along with the through groove 4. The next set of nuts to be processed moves synchronously to the side of the positioning cylinder 9. The axis of the nut is aligned with the axis of the drill-and-chamfer tool and the tapping and chamfering tool, so as to facilitate the drilling, tapping and chamfering of the nuts, so as to realize multi-process continuous processing, effectively shorten the process flow, improve processing efficiency and product quality stability.

[0061] When the next set of nuts to be processed moves synchronously to the side of the positioning cylinder 9, and the rotating ring 3 rotates to the point where the through groove 4 of the processed nut intersects with the fan-shaped channel 10 of the fixed ring 2, the through groove 4 no longer connects with the through hole 11 and no longer has an adsorption effect on the nut, the electric slide rail 5 drives the slide block 6 to move the drill-and-chamfer integrated tool spindle box 7 towards the rotating ring 3. When drilling and chamfering the next set of nuts, the top material rod 26 fixed on one side of the spindle box 7 advances synchronously, squeezing the processed nut. The nut is pushed by the top material rod 26 and moves to the side of the rotating ring 3 away from the top material rod 26, falling into the storage frame 28. The processed nut is collected through the storage frame 28.

[0062] During processing, such as drilling, tapping, and chamfering, waste materials such as metal shavings fall through the gap between the positioning cylinder 9 and the nut into the arc-shaped discharge chute 16 at the bottom of the positioning cylinder 9, and directly into the opening of the aligned collection frame 14 below, preventing waste materials from scattering outside the equipment. At the same time, negative pressure creates suction in the collection frame 14, which can quickly suck metal shavings, dust and other waste materials into the fixed cylinder 1 through the opening of the collection frame 14, avoiding the accumulation of waste materials below the positioning cylinder 9 or near the through groove 4. For thin shavings generated by chamfering, negative pressure adsorption can make up for the inadequacy of relying solely on gravity to fall, ensuring that all kinds of waste materials can be collected efficiently.

[0063] When the rotating ring 3 completes one station rotation and the processing cycle of a single nut ends, the screw feeding shaft 21 is driven by the dual-axis motor 17 and the transmission belt 24 to complete one complete rotation, pushing the waste material from the end away from the negative pressure pump 13 in the fixed cylinder 1 towards the discharge port, ensuring that the waste material is effectively transported to the vicinity of the discharge port, so that the waste material processing is completely synchronized with the processing flow, avoiding resource waste, realizing processing and material discharge at the same time, and significantly improving production efficiency.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention.
