Description

Technical Field

[0001] The present application relates to the technical field of bolt production equipment manufacturing, and in particular to an automated bolt production line. Background Art

[0002] When processing bolts in industrial production, the steel blank is first heated and rolled into a coil, and then the coil is drawn and cold headed in sequence to produce a bolt blank; then, the bolt blank is surface turned to improve its surface quality and obtain a bolt blank with a certain shape and size; then, the stud of the bolt blank is threaded to finally obtain a formed bolt.

[0003] At present, in the relevant industry, due to the different equipment used in the bolt blank forming process and the threading process, bolt manufacturers usually manually remove the bolt blank from the surface turning station after the bolt blank is made. After a certain number of bolt blanks are produced, the staff will move them to the threading station and manually install the bolt blanks one by one at the threading station for threading operations.

[0004] With respect to the above-mentioned related technologies, the inventors believe that manually transferring a certain number of bolt blanks from the surface turning station to the threading station places high labor intensity on the workers; moreover, the transfer efficiency is low, thereby reducing the bolt processing efficiency, and there is room for improvement.

[0008] By adopting the above technical solution, during the bolt production operation, the staff first places the bolt blank in the material trough on the support table; the first industrial robot arm is then started, and its end rotates to the top of the support table, and picks up the bolt blank on the support table, and then drives the bolt blank from the support table to the working cabin of the surface processing lathe, and installs the bolt blank on the surface processing lathe; then, the first industrial robot arm withdraws from the working cabin of the surface processing lathe, and the surface processing lathe is immediately started to turn the surface of the bolt blank to form the corresponding bolt blank; after the bolt blank is formed, the first industrial robot arm An industrial robot arm reaches into the working cabin of the surface processing lathe again to pick up the bolt blank, and transfers the bolt blank to the turntable; then, the end of the second industrial robot arm moves to the top of the turntable and picks up the bolt blank on the turntable; then, the bolt blank is installed on the threading lathe to complete the loading operation of the bolt blank; this method replaces the manual operation of transferring the bolt blank from the surface turning station to the threading station, with a high degree of automation, effectively reducing the labor intensity of the staff, and shortening the bolt blank transfer time, thereby effectively improving the efficiency of bolt production operations.

[0009] Preferably, a first electromagnetic chuck and a second electromagnetic chuck are disposed at intervals at the end of the first industrial robot arm, and a first automatic gripper and a second automatic gripper are disposed at intervals at the end of the second industrial robot arm.

[0010] By adopting the above technical scheme, in actual operation, the staff first places the bolt blank in the material storage slot on the support table, and keeps the bolt cap of the bolt blank facing upward; then, the end of the first industrial robot arm moves to the top of the support table, and makes the first electromagnetic suction cup or the second electromagnetic suction cup drop to the top of the material storage slot; the first electromagnetic suction cup or the second electromagnetic suction cup immediately absorbs the bolt cap of the bolt blank in the material storage slot, thereby driving the bolt blank to separate from the support table; as the first industrial robot arm swings, the bolt blank is brought to the feed port of the surface processing lathe; after the original bolt blank in the surface processing lathe is turned, the first industrial robot arm extends into the working cabin of the surface processing lathe, and makes the second electromagnetic suction cup or the first electromagnetic suction cup carry the formed bolt blank; then, the first industrial robot arm rotates, so that the second electromagnetic suction cup or the first electromagnetic suction cup drives the bolt blank to separate from the surface processing lathe, and at the same time, the first electromagnetic suction cup or the second electromagnetic suction cup drives the new bolt blank to be installed on the turning station of the surface processing lathe, thereby completing the unloading of the bolt blank and the loading of the bolt blank.

[0011] Then, the first industrial robot arm detaches from the working cabin of the surface processing lathe and moves to the turntable, and places the bolt blank on the turntable; at the same time, the surface processing lathe performs surface turning on the bolt blank to obtain a new bolt blank; and the second industrial robot arm drives the first automatic gripper or the second automatic gripper installed thereon to move above the turntable, and the first automatic gripper or the second automatic gripper picks up the bolt blank on the turntable and transfers it to the feed port of the thread making lathe; after the original bolt blank in the thread making lathe is processed, the second industrial robot arm extends into the working cabin of the thread making lathe, and uses the second automatic gripper or the first automatic gripper to pick up the formed bolt on the thread making lathe; then, the second industrial robot arm rotates, so that the second automatic gripper or the first automatic gripper drives the formed bolt to detach from the thread making lathe, and at the same time, the first automatic gripper or the second automatic gripper installs the new bolt blank to the thread turning station of the thread making lathe, thereby completing the unloading of the formed bolt and the loading of the bolt blank.

[0012] The first electromagnetic chuck and the second electromagnetic chuck are used to achieve seamless connection between the unloading operation of the bolt blank and the loading operation of the bolt blank; at the same time, the first automatic gripper and the second automatic gripper are used to achieve seamless connection between the unloading operation of the formed bolt and the loading operation of the bolt blank; the materials are picked up and loaded immediately at the same workstation, which effectively saves production operation hours and effectively improves the efficiency of bolt processing operations.

[0014] By adopting the above technical solution, when the first industrial robot arm places the bolt blank in the placement groove, the worktable of the slide slides horizontally relative to the slide base, and drives the turntable to move toward the side of the second industrial robot arm; then, the second industrial robot arm swings to the top of the turntable and picks up the bolt blank in the placement groove, thereby completing the bolt blank picking operation; with the help of the slide driving the turntable to make reciprocating linear motion between the first industrial robot arm and the second industrial robot arm, it helps to reduce the volume of the first industrial robot arm and the second industrial robot arm installed on the frame, thereby effectively improving the convenience of manufacturing the automated bolt production line; at the same time, it helps to reduce the floor space of the automated bolt production line and save the company's production costs.

[0015] Preferably, a mounting frame is provided on the frame for lifting and lowering above the turntable, and a first driving member for driving the mounting frame to lift and lower is provided on the frame; a storage table is rotatably provided on the mounting frame, and the rotation axis direction of the storage table is horizontally arranged, and a second driving member for driving the storage table to rotate is provided on the frame; a storage groove is provided on one side of the storage table in the thickness direction, and a third electromagnetic suction cup is provided at the bottom of the storage groove.

[0016] By adopting the above technical solution, during the production operation, when the first industrial robot arm places the bolt blank into the storage slot of the storage table, the circuit of the third electromagnetic suction cup is connected, generating magnetic force, so that the bolt blank is firmly adsorbed in the storage slot, and the bolt cap of the bolt blank is set upward at this time; then, the second driving member is started to drive the storage table to rotate 180 degrees around its own rotation axis, so that the nut of the bolt blank is set downward; then, the first driving member is started to drive the storage table to descend to the surface of the turnover table and align the storage slot with the placement slot; then, the circuit of the third electromagnetic suction cup is disconnected, so that one end of the bolt cap of the bolt blank falls into the placement slot, thereby completing the conveying operation of the bolt blank; then, the first driving member drives the storage table to rise and reset, and the second driving member drives the storage table to rotate 180 degrees around its own rotation axis, so that the opening of the storage slot is restored to be set upward to receive the next bolt blank.

[0017] In this way, after the bolt blank falls into the placement groove, one end of its stud faces upward. When the first automatic gripper or the second automatic gripper feeds the bolt blank, it holds the stud end of the bolt blank, thereby facilitating the first automatic gripper or the second automatic gripper to load one end of the bolt cap of the corresponding bolt blank into the three-jaw chuck of the thread-making lathe, thereby completing the loading operation of the bolt blank and effectively improving the convenience of loading the bolt blank into the thread-making lathe.

[0018] Preferably, a vibration plate for stacking bolt blanks is installed on the frame, and a discharge port of the spiral conveying track of the vibration plate is connected to a slideway, and one end of the discharge port of the slideway is connected to a material trough.

[0019] By adopting the above technical scheme, in actual production, after the bolt blanks are produced, they fall into the vibration plate, which is used to generate vibration, and the bolt blanks are stacked in sequence, and the stacked bolt blanks are transferred to the slide; then, the slide conveys the bolt blanks one by one to the material trough, thereby completing the feeding operation of the bolt blanks; the bolt blanks are stacked and transferred in sequence by the vibration plate and the slide, which reduces the staff's operation of loading the bolt blanks one by one, and improves the automation level of the bolt blank loading operation, thereby effectively reducing the staff's work intensity and saving time and effort.

[0021] By adopting the above technical solution, when a bolt blank slides from the slide into the feeding trough, the third driving component drives the support table to slide horizontally along the width direction of the slide outlet, so that the side wall of the support table with the loading port slides horizontally relative to the end wall of the slide outlet; at this time, the side wall of the feeding trough blocks the slide outlet; after the first industrial robot arm takes the bolt blank in the feeding trough, the third driving component starts to drive the support table to slide, and when the loading port is reconnected to the slide outlet, a bolt blank downstream of the slide falls into the feeding trough; then the third driving component drives the support table to slide again, and the cycle is repeated, thereby realizing the one-by-one feeding of the bolt blanks to the support table, effectively ensuring the orderly loading operation of the bolt blanks, and then effectively ensuring the stability of the bolt production process.

[0022] Preferably, hatches are slidably provided at the feed ports of the working cabins of the surface machining lathe and the thread making lathe, and control cylinders for controlling the opening and closing of the hatches are provided on the bodies of the surface machining lathe and the thread making lathe.

[0024] Preferably, a conveyor belt is provided on the frame, and the end of the conveyor belt is connected to a collection box.

[0025] By adopting the above technical solution, after the bolt processing is completed, the second industrial robot arm takes the formed bolts out of the working cabin of the thread making lathe and places them on the conveyor belt. The conveyor belt then transports the formed bolts to the collection box at the corresponding position for storage, thereby replacing the manual operation of transporting the formed bolts to the corresponding position for storage, further improving the degree of automation of the automated bolt production line, saving time and effort, and helping to reduce the company's labor costs.

[0028] The bolt blanks are stacked and transported by means of a vibration plate, a slideway and a support platform, and the support platform is driven to slide horizontally by a third driving member to feed the bolt blanks one by one, effectively ensuring the stability of the bolt production process. The structure is simple, easy to manufacture, and effectively saves the production cost of the enterprise;

[0029] By controlling the cylinder to drive the hatch to open and close, the system has a high degree of automation and saves manpower.

Then, the circuit of the corresponding second electromagnetic suction cup 312 or the first electromagnetic suction cup 311 is disconnected, so that the stud end of the bolt blank falls into the storage slot 191; the circuit of the third electromagnetic suction cup 10 at the bottom of the storage slot 191 is immediately connected, and the bolt blank is firmly adsorbed in the storage slot 191; then, the drive motor 91 is started, driving the storage table 19 to rotate 180 degrees around its own rotation axis, so that the bolt cap of the bolt blank is set downward; then, the first air The piston rod of cylinder 181 contracts, driving the storage table 19 to descend to the top of the turntable 14, and placing the bolt blank opposite the placement slot 141; then, the circuit of the third electromagnetic suction cup 10 is disconnected, and the magnetic force disappears, causing one end of the bolt cap of the bolt blank to fall into the placement slot 141; then, the slide 8 is started, and the working table of the slide 8 drives the bolt blank stored on the turntable 14 to move toward the side of the second industrial robot arm 4; then, the second industrial robot arm 4 picks up one end of the stud of the bolt blank in the placement slot 141, and installs it on the thread-making lathe 12, thereby completing the loading operation of the bolt blank.

[0054] The implementation principle of an automated bolt production line in an embodiment of the present application is as follows: in actual production, after the bolt blanks produced in the previous process are transferred to the vibration plate 21, the vibration plate 21 vibrates, stacks the bolt blanks in sequence and transfers them to the slide 22; the bolt blanks then slide along the slide 22 to one side of the support platform 13; in the initial state, the loading port 132 of the support platform 13 is connected with the discharge port of the slide 22, and a bolt blank downstream of the slide 22 slides into the loading trough 131; then, the piston rod of the third cylinder 51 extends and drives the support platform 13 to slide horizontally, so that the side wall of the support platform 13 blocks the discharge port of the slide 22, preventing the bolt blanks in the slide 22 from continuing to slide down, thereby realizing the one-by-one feeding of the bolt blanks in the slide 22 to the support platform 13.

[0055] Afterwards, the first industrial robot arm 3 moves to the top of the support platform 13, and makes the first electromagnetic suction cup 311 or the second electromagnetic suction cup 312 fall onto the bolt embryo, and the circuit of the first electromagnetic suction cup 311 or the second electromagnetic suction cup 312 is immediately connected, so that the bolt cap of the bolt embryo is adsorbed on the first electromagnetic suction cup 311 or the second electromagnetic suction cup 312; then, the first industrial robot arm 3 drives the bolt embryo to move to the feed port of the surface processing lathe 11; after the original bolt embryo in the surface processing lathe 11 is turned, the first industrial robot arm 3 The robot arm 3 extends into the working cabin of the surface processing lathe 11, and uses the second electromagnetic suction cup 312 or the first electromagnetic suction cup 311 to remove the formed threaded blank; then, the first industrial robot arm 3 rotates to install the bolt blank picked up by the first electromagnetic suction cup 311 or the second electromagnetic suction cup 312 on the turning station of the surface processing lathe 11, and then, the first industrial robot arm 3 drives the formed bolt blank to withdraw from the working cabin of the surface processing lathe 11, thereby completing the unloading of the bolt blank and the loading of the bolt blank.

[0056] Furthermore, the first industrial robot arm 3 drives the bolt blank to be transported to the top of the storage table 19, and places the bolt blank into the storage slot 191; the third electromagnetic suction cup 10 firmly adsorbs the bolt blank into the storage slot 191; then, the driving motor 91 drives the storage table 19 to rotate 180 degrees around its own rotation axis, and the piston rod of the first cylinder 181 contracts immediately, so that the bolt blank in the storage slot 191 moves to just above the placement slot 141; then, the circuit of the third electromagnetic suction cup 10 is disconnected, and the magnetic force of the third electromagnetic suction cup 10 disappears, so that one end of the bolt cap of the bolt blank falls into the placement slot 141; then, the workbench of the slide 8 drives the bolt blank stored in the placement slot 141 to move toward the side of the second industrial robot arm 4.

[0057] Subsequently, the second industrial robot arm 4 is started, and the first automatic gripper 41 or the second automatic gripper 42 picks up the bolt blank on the turntable 14 and drives it to move to the feed port of the threading lathe 12; after the original bolt blank in the threading lathe 12 is processed, the second industrial robot arm 4 extends into the working cabin of the threading lathe 12, and uses the second automatic gripper 42 or the first automatic gripper 41 to remove the formed bolt; then, the second industrial robot arm 4 rotates, and installs the bolt blank picked up by the first automatic gripper 41 or the second automatic gripper 42 on the threading lathe 12, and then withdraws from the working cabin of the threading lathe 12, thereby completing the unloading operation of the formed bolt and the loading operation of the bolt blank.

[0058] This method is used to produce bolts, and the entire process of making bolts from bolt blanks can be automated, which effectively reduces the workload of workers and improves the production efficiency of bolts.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
