[0002] Conventional nut side hole machining equipment usually requires one worker and one drilling machine for production. This production method consumes high production costs. In order to improve the efficiency of nut production, an automated machining method needs to be selected. Conventional automated machining equipment can only process one nut at a time when running automatically. In order to improve the efficiency of automated machining, the machining equipment needs to be improved. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a fully automatic nut processing equipment, which has the characteristics of improving nut processing efficiency and reducing production costs.

[0004] The technical solution adopted by the present invention to solve its technical problem is: to provide a fully automatic nut processing equipment, including a robot arm, a drilling machine tool, a material rack and a vibratory feeder support, wherein a drilling machine tool is installed on one side of the robot arm, a material rack is installed on the rear side between the robot arm and the drilling machine tool, and a vibratory feeder support is installed on the rear side of the material rack.

[0005] The material rack includes a material rack body, a discharge chute, a discharge rack, and a drying air outlet. The upper end of the material rack body is equipped with a horizontally arranged discharge rack, which has several nut placement holes. The material rack body is hollow inside. A drying air outlet is opened on the upper front side of the material rack body, and an air blowing pipe is installed inside the drying air outlet. The lower front side of the material rack body is equipped with a discharge chute, which slopes downward at the end near the drilling machine tool.

[0006] The robotic arm is equipped with a magnetic nut fixing bracket, the vibratory feeder is installed inside the vibratory feeder bracket, and the output end of the vibratory feeder is provided with an arrangement track, which passes through the vibratory feeder bracket.

[0007] The drilling machine tool is provided with a machine tool opening on the side near the robot arm, and a nut processing fixture arranged longitudinally is installed in the lower bottom of the machine tool opening;

[0008] When performing side hole machining, the robotic arm uses a magnetic nut holder to remove the unprocessed nuts one by one from the arranged track. The robotic arm then places the nuts one by one into the nut placement holes on the feed rack. When the feed rack is full of nuts, a row of magnetic structures on the magnetic nut holder attracts a row of nuts. The robotic arm then transports the nuts to the nut processing fixture, which fixes the nuts in place. After that, a drilling machine drills holes in the nuts on the side. Once completed, the robotic arm and the magnetic nut holder remove the processed nuts and insert them into a drying air vent for drying. Finally, the nuts are fed into the discharge chute for discharge.

[0009] The drying air vent is designed to facilitate the insertion of the magnetic nut holder. At the same time, the air pipe inside the drying air vent will discharge a large amount of dry gas to dry the magnetic nut holder and the processed nuts, ensuring that the nuts are dry and preventing dust from sticking to the exposed nuts.

[0010] In this technical solution, to improve production efficiency and facilitate the simultaneous processing of multiple nuts, it is necessary to arrange the unprocessed nuts in a reasonable manner. A vibratory feeder bracket is installed to facilitate the discharge of the products, and an arranging track is used to output the nuts normally. This allows the robot arm to transport the nuts one by one to the feeding rack. The feeding rack is installed to facilitate the arrangement of nuts, and the nut placement holes on the feeding rack are used to store multiple nuts.

[0015] As a supplement to this technical solution, the upper end of the material rack body is symmetrically provided with pads for supporting both ends of the discharge rack, and the middle two sides of the material rack body are equipped with pipe bases for connecting air blowing pipes.

[0016] In this technical solution, mounting blocks are used to facilitate the installation of the material discharge rack, so that the material discharge rack is in a suspended state, and pipe bases are used to facilitate the fixation of the air blowing pipe.

[0017] As a supplement to this technical solution, the magnetic nut fixing bracket includes a central transverse support rod, a central docking shaft, a longitudinal support, cable docking posts, an electromagnet structure, and a product fixing head.

Several ejector cylinders with their spindles facing backwards are evenly installed side-by-side on the rear side of the ejector cylinder fixing bracket. A chip removal platform is installed on the rear side of the left support. A nut fixing block is installed on the upper end of the chip removal platform, and a nut cover plate is installed on the upper surface of the nut fixing block. The nut fixing block and the nut cover plate are provided with several nut processing cavities. The ejection cylinders correspond one-to-one with the nut processing cavities. The spindle of the ejection cylinder is inserted into the nut processing cavity. The nut cover plate is provided with several processing through holes corresponding to the nut processing cavities.

The nut pushing cylinders correspond one-to-one with the nut processing cavities. The rear side of the nut fixing block is equipped with a lifting platform. The lifting platform is provided with several nut placement slots corresponding one-to-one with the nut processing cavities.

[0020] In this technical solution, a nut processing fixture is installed to simultaneously fix multiple nuts, facilitating the machining of multiple nuts by the drilling machine. Simultaneously, a push-out cylinder fixing bracket is installed to fix multiple push-out cylinders, allowing the machined nuts to be easily pushed out of the nut processing cavity. A chip removal platform is installed to remove waste chips generated during processing. Nut fixing blocks and nut cover plates are installed to facilitate the formation of the nut processing cavity, preventing waste chips from flying out during processing and also facilitating nut fixation. A lifting platform is installed to raise the nuts to the height aligned with the nut processing cavity, and then a nut pushing cylinder is used to push the nuts into the nut processing cavity.

[0021] A limiting protrusion is provided at the bottom of the nut processing cavity to hold the lower side of the nut in place, ensuring that the nut remains in the same position after entering the nut processing cavity.

[0022] As a supplement to this technical solution, the lower part of the chip removal platform is uniformly provided with a number of chip removal holes that correspond one-to-one with the nut processing cavity. A chip removal channel is provided between the nut processing cavity and the chip removal holes. The lower part of the cylinder integration platform is equipped with a number of chip removal cylinders that correspond one-to-one with the chip removal holes. A chip removal push block that is inserted into the chip removal hole is installed on the main shaft of the chip removal cylinder.

[0023] In this technical solution, a chip removal hole is set to remove waste chips. A chip removal channel is set on the nut machining cavity to facilitate the flow of waste chips generated during the machining process into the chip removal hole. At the same time, a chip removal cylinder is used to drive the chip removal push block to move, and the chip removal push block can push the waste chips out of the chip removal hole.

[0024] As a supplement to this technical solution, several lubricant injection blocks are installed side by side on the front end face between the nut fixing block and the nut cover plate. Each lubricant injection block corresponds to a nut machining cavity. The upper and lower parts of the lubricant injection blocks are respectively provided with upper and lower channels penetrating both sides of the lubricant injection block. The upper rear side of the lubricant injection block is provided with a mating protrusion that is embedded in the nut fixing block and the nut cover plate. The middle of the mating protrusion is provided with a central through hole that matches the spindle of the ejector cylinder. The mating protrusion is uniformly provided with injection oblique holes that communicate with the upper channel. The injection oblique holes communicate with the nut machining cavity. The lower rear side of the lubricant injection block is provided with a lower mating hole that communicates with the lower channel. A sealing ring is embedded in the outer ring of the lower mating hole.

[0025] In this technical solution, the drilling machine generates a large amount of waste chips and heat during processing. The heat will affect the drilling quality, and the waste chips during the drilling process will cause additional wear. Therefore, it is necessary to set up a lubricant injection block to ensure that the nut processing cavity is always filled with lubricant. The lubricant can help cool the processing part and also facilitate the removal of waste chips.

[0026] In this technical solution, two flow channels are formed by setting an upper channel and a lower channel. The two flow channels are used to connect the nut machining cavity and the chip removal hole respectively. An injection inclined hole is set to evenly inject lubricant into the nut machining cavity. A lower docking hole is set to facilitate docking with the chip removal hole. A sealing ring is set to seal this part.

[0027] As a supplement to this technical solution, the front side of the nut fixing block is provided with several liquid inlet channels that connect with the lower docking hole.

[0029] In this technical solution, a guide column structure is set to ensure the smooth operation of the lifting platform, and a lifting cylinder is set to increase the height of the lifting platform.

[0030] Adjacent lubricant injection blocks are connected by pipes. The ends of the leftmost and rightmost lubricant injection blocks are connected to external lubricant injectors by connecting pipes, which facilitates continuous circulation and injection of lubricant.

[0031] In this technical solution, pipes are used to connect the lubricant injection blocks, making the lubricant injection blocks a whole, which facilitates centralized and unified oil supply to the nut machining cavity. At the same time, the connecting pipes at both ends are used to achieve lubricant circulation.

[0032] The lubricant flowing out from the nut machining fixture is recycled at the bottom of the drilling rig and filtered to ensure its recycling. At the same time, the filtered lubricant is injected back into the lubricant injection block by an oil pump, thus achieving the rational use of the lubricant.

[0033] As a supplement to this technical solution, a limiting rib is provided on the main shaft of the ejection cylinder to limit the ejection distance of the ejection cylinder, so as to prevent the nut from falling off the nut fixing block when ejecting the nut, and to facilitate the magnetic nut fixing bracket to pick up the nut and realize the rapid transfer of the nut.

[0034] After the nut is drilled on the side, it needs to be pushed out by the ejection cylinder. However, it is necessary to prevent the nut from falling off the nut fixing block. Therefore, a limiting rib is required to control the extension of the spindle of the ejection cylinder and ensure that the length of the nut pushed out is half of the total length of the nut.

[0035] As a supplement to this technical solution, a sealing cover is embedded in the front side of the lubricant injection block.

[0036] As a supplement to this technical solution, a protective cover structure is installed at the rear of the base plate structure, and a waste chip ejection assembly is installed on one side of the nut processing fixture. The waste chip ejection assembly adopts a cylinder structure, and a waste chip pusher is installed on the main shaft of the cylinder structure. The waste chip pusher and the protective cover structure in the middle of the base plate structure correspond to each other.

[0037] Since the magnetic nut holder has two rows of longitudinal supports, which serve as two sets of nut removal structures, a clearance groove is provided below the drying air vent of the material rack body to facilitate the magnetic nut holder's insertion into the drying air vent and prevent the magnetic nut holder from contacting the material rack body.

[0038] To ensure smooth flow of lubricant in the upper channel and nut machining cavity, there are four injection angle holes arranged in a cross shape, with the front end of the injection angle holes inclined towards the center of the mating protrusion.

[0039] Beneficial effects: This invention relates to a fully automatic nut processing equipment. It utilizes a vibratory feeder support for easy product discharge, an array of tracks for normal nut output, and a robotic arm to transport nuts one by one to a feeding rack. The feeding rack facilitates nut arrangement, and nut placement holes on the rack store multiple nuts. A magnetic nut holder is used for overall transport of the nuts in the rack. A nut processing fixture is installed to process multiple nuts. This equipment improves nut processing efficiency and reduces production costs. Attached Figure Description

[0086] like Figures 21-25 As shown, as a supplement to this technical solution, several lubricant injection blocks 43 are installed side by side on the front end face between the nut fixing block 41 and the nut cover plate 42. The lubricant injection blocks 43 correspond one-to-one with the nut processing cavity 62. The upper and lower parts of the lubricant injection blocks 43 are respectively provided with an upper channel 54 and a lower channel 55 penetrating both sides of the lubricant injection block 43. The upper rear side of the lubricant injection block 43 is provided with a mating protrusion 59 that is embedded in the nut fixing block 41 and the nut cover plate 42. The middle part of the mating protrusion 59 is provided with a central through hole that matches the main shaft of the ejector cylinder 39. The mating protrusion 59 is uniformly provided with injection inclined holes 58 that communicate with the upper channel 54. The injection inclined holes 58 communicate with the nut processing cavity 62. The lower rear side of the lubricant injection block 43 is provided with a lower mating hole 60 that communicates with the lower channel 55. A sealing ring 61 is embedded in the outer ring of the lower mating hole 60.

[0087] In this technical solution, the drilling machine generates a large amount of waste chips and heat during processing. The heat will affect the drilling quality, and the waste chips during the drilling process will cause additional wear. Therefore, a lubricant injection block 43 is required to ensure that the nut processing cavity 62 is always filled with lubricant. The lubricant can help cool the processing part and also facilitate the removal of waste chips.

[0088] In this technical solution, two flow channels are formed by setting an upper channel 54 and a lower channel 55. The two flow channels are used to connect the nut processing cavity 62 and the chip removal hole 63 respectively. An injection inclined hole 58 is set to evenly inject lubricant into the nut processing cavity 62. A lower docking hole 60 is set to facilitate docking with the chip removal hole 63. A sealing ring 61 is set to seal this part.

[0089] like Figures 17-19As shown, as a supplement to this technical solution, the front side of the nut fixing block 41 is provided with several liquid inlet channels 56 that are connected to the lower docking holes 60. The rear end of the liquid inlet channel 56 is provided with a tapered hole 57 with a gradually decreasing diameter. The rear end of the tapered hole 57 is connected to the chip removal hole 63. In this technical solution, the liquid inlet channel 56 is provided to facilitate the passage of lubricating fluid, and the tapered hole 57 is provided to facilitate the control of the amount of lubricating fluid injected.

[0090] As a supplement to this technical solution, guide column structures 49 are vertically installed at both ends of the lifting platform 45. The lower end of the guide column structure 49 passes through the lifting platform 45 and is connected to the base plate structure 36. A lifting cylinder 50 with its main shaft facing upward is symmetrically installed in the middle of the base plate structure 36. The main shaft of the lifting cylinder 50 is connected to the lifting platform 45.

[0091] In this technical solution, a guide column structure 49 is set to ensure the smooth operation of the lifting platform 45, and a lifting cylinder 50 is set to raise the height of the lifting platform 45.

[0092] like Figure 20 As shown, adjacent lubricant injection blocks 43 are connected by pipes 64. The ends of the leftmost and rightmost lubricant injection blocks 43 are connected to external lubricant injectors by connecting pipes, which facilitates the continuous injection of lubricant.

[0093] In this technical solution, pipe 64 is used to connect the lubricant injection blocks 43, so that the lubricant injection blocks 43 form a whole, which facilitates centralized and unified oil supply to the nut processing cavity 62. At the same time, the connecting pipes at both ends are used to realize the circulation of lubricant.

[0094] The lubricant that flows out from the nut processing fixture 28 will be recycled at the bottom of the drilling rig platform 2 and filtered to ensure that the lubricant is recycled again. At the same time, the filtered lubricant will be injected back into the lubricant injection block 43 by the oil pump, so as to achieve the rational use of the lubricant.

[0095] As a supplement to this technical solution, a limiting rib is provided on the main shaft of the ejection cylinder 39 to limit the ejection distance of the ejection cylinder 39, so as to prevent the nut from falling off the nut fixing block 41 when ejecting the nut, so as to facilitate the magnetic nut fixing bracket 4 to pick up the nut and realize the rapid transfer of the nut.

[0096] After the nut is drilled on the side, it needs to be pushed out by the push-out cylinder 39. However, it is necessary to prevent the nut from falling off the nut fixing block 41. Therefore, a limiting rib is required to control the extension of the spindle of the push-out cylinder 39, ensuring that the length of the nut pushed out is half of the total length of the nut.

[0097] As a supplement to this technical solution, a sealing cover plate 52 is embedded and installed on the front side of the lubricant injection block 43.

[0098] As a supplement to this technical solution, a protective cover structure is installed at the rear of the base plate structure 36, and a waste chip ejection assembly 35 is installed on one side of the nut processing fixture 28. The waste chip ejection assembly 35 adopts a cylinder structure, and a waste chip pusher is installed on the main shaft of the cylinder structure. The waste chip pusher and the protective cover structure in the middle of the base plate structure 36 correspond to each other.

[0099] Since the magnetic nut holder 4 is provided with two rows of longitudinal supports 31, which serve as two sets of nut removal structures, a clearance groove 8 is provided below the drying air outlet 7 of the material rack body 6 to facilitate the magnetic nut holder 4 to extend into the drying air outlet 7 and prevent the magnetic nut holder 4 from touching the material rack body 6.

[0100] To ensure smooth flow of lubricant in the upper channel 54 and the nut machining cavity 62, there are four injection inclined holes 58 arranged in a cross shape, with the front end of the injection inclined holes 58 inclined towards the center of the mating protrusion 59.

[0101] Example

[0102] like Figure 10 As shown, this device can use a robot arm 1 to process two sets of drilling machines 2, further improving processing efficiency and reducing the overall cost of nuts. At the same time, the robot arm 1 in this device is a conventional six-axis robot arm, such as the robot arm produced by Wuhu Moka Robot Technology Co., Ltd. and Dongguan Minghao Automation Co., Ltd., while the drilling machine arm 2 is a conventional milling machine that can be purchased on the market and is capable of drilling.

[0103] like Figure 1As shown, when this device is in production, the vibratory feeder 20 inside the vibratory feeder bracket 5 is first activated, arranging the unprocessed nuts one by one on the arranging track 15. Then, the robot arm 1 transfers the nuts one by one to the feeding rack 9. The nut placement holes 21 on the feeding rack 9 can hold the nuts. During the transfer, one product fixing head 34 of the magnetic nut fixing bracket 4 on the robot arm 1 completes the placement of the nuts. After completion, a row of product fixing heads 34 attracts the nuts on the feeding rack 9. Then, the robot arm 1 places all the nuts onto the lifting platform 45. The lifting platform 45 then transports the nuts to a position at the same height as the nut fixing block 41, where the nuts on the lifting platform 45 are processed. The cavity 62 and the nut placement slot are aligned. After that, the nut pushing cylinder 47 is activated, which pushes the nut into the nut processing cavity 62. The limiting protrusion on the lower side wall of the nut processing cavity 62 positions the nut. After that, the drilling machine 2 is activated, and the drill bit of the drilling machine 2 extends directly into the processing through hole 51 to drill the nut. After that, the ejection cylinder 39 is activated to eject the nut from the nut processing cavity 62. Then, the nut is completely removed by the magnetic nut fixing bracket 4, and the processed nut is sent to the drying air outlet 7 by the robot arm 1. The air blowing pipe 24 in the drying air outlet 7 performs the drying action. After that, the robot arm 1 moves the nut to the discharge chute 10 for easy overall product output.

[0104] When the drilling machine 2 is performing drilling, the robot arm 2 controls the magnetic nut fixing bracket 4 to perform the nut re-arrangement operation, thereby realizing the continuous operation of the equipment.

[0105] During the drilling process, the lubricant injection block 43 needs to continuously output lubricant to ensure that there is an appropriate amount of lubricant in the nut machining cavity 62.
