Description

Technical Field

[0001] This invention belongs to the field of eyeglasses manufacturing technology, and in particular relates to a rotary five-axis fully automatic hinge machine. Background Technology

[0002] A pair of glasses typically consists of a frame, lenses, and temples. A hinge structure is usually installed between the frame and temples to facilitate the opening and closing of the temples. Equipment that processes the hinge structure through cutting is called a hinge machine. Traditional hinge machines cannot adjust the angle of the cutting tool during cutting, thus they cannot process hinge structures with a certain angle. This means that this part of the hinge structure is usually operated manually, which not only makes it difficult to control precision but also increases labor costs and reduces product quality. Some alternatives, such as the double-headed nail hinge cutting machine disclosed in Chinese patent application number (CN201822208534.X), use a cutting axis angle adjustment mechanism to adjust the angle of the cutting electric spindle, thereby tilting the cutting tool to facilitate the processing of hinge structures with a certain angle. However, this cutting axis angle adjustment mechanism is manually adjustable, resulting in low adjustment precision and convenience, and can easily affect product quality. Summary of the Invention

[0065] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0066] Example 1:

[0067] This embodiment provides a rotary five-axis fully automatic hinge machine, including:

[0068] Frame 1, with a worktable 2 mounted on frame 1;

[0069] The cutting mechanism 3 is mounted on the worktable 2 and includes a first cutting group 30.

[0071] Displacement mechanism 5 is mounted on worktable 2 and is used for movement during blank processing;

[0072] Feeding mechanism 6 is mounted on displacement mechanism 5 and is used for feeding and clamping the blank.

[0073] As can be seen from this embodiment, by using a rotating tool holder 4, it is convenient to adjust the angle of the first cutting group 30, which in turn facilitates the adjustment of the angle of the cutting tool, making it convenient to process the hinge structure with a certain angle. The displacement mechanism 5 and the feeding mechanism 6 facilitate the movement of the blank and improve the processing accuracy.

[0074] Example 2:

[0075] This embodiment provides a rotary five-axis fully automatic hinge machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the rotary tool holder 4 includes:

[0076] Plate 40, plate 40 is used to mount the first cutting assembly 30;

[0077] Support plate 41, there are two support plates 41, which are vertically set at both ends of the flat plate 40, and support platforms 42 are provided for supporting both ends of the flat plate 40.

[0078] Indexer 43 is mounted on worktable 2, and support plate 41 is mounted on the output end of indexer 43.

[0079] The first motor 44 is mounted on the worktable 2 and is used to drive the first indexer 43;

[0080] The first motor 44 is preferably a servo motor.

[0081] As can be seen from this embodiment, by using an indexer 43 and driving it with a first motor 44, the accuracy and convenience of adjusting the angle of the first cutting group 30 are improved, and the automatic adjustment meets the requirements of fully automatic production of hinge structures, ensuring production efficiency. At the same time, it can also meet the cutting processing of a single hinge structure with two tilt angles, improving processing efficiency and processing accuracy.

[0082] Example 3:

[0083] This embodiment provides a rotary five-axis fully automatic hinge machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the cutting mechanism 3 further includes:

[0084] The second cutting group 31 includes a second motor 310 and a second cutting tool group 311, which are installed on the worktable 2. There are two of them, located on both sides of the first cutting group 30 respectively.

[0085] The third cutting group 32 includes a third motor 320 and a third cutting tool group 321, and is mounted on the worktable 2 and located above the first cutting group 30.

[0086] The cutting assembly 33 includes a fourth motor 330 and a saw blade 331, and is mounted on the worktable 2 and located on the side of the first cutting group 30.

[0087] The first cutting group 30 includes a fifth motor 300 and a first cutting tool group 301, and the first cutting tool group 301, the second cutting tool group 311 and the third cutting tool group 321 are arranged perpendicular to each other in the axial direction.

[0088] Meanwhile, the specific type, quantity, and model of cutting tools used in the first cutting tool group 301, the second cutting tool group 311, and the third cutting tool group 321 will be determined according to actual needs, and will not be elaborated on here. Furthermore, the second motor 310, the third motor 320, the fourth motor 330, and the fifth motor 300 are preferably servo motors.

[0089] As can be seen from this embodiment, by using the first cutting blade group 301, the second cutting blade group 311, and the third cutting blade group 321 arranged vertically in pairs, the accuracy and adaptability of the hinge structure processing are improved, which can meet the processing of different hinge structures and improve the applicability of the hinge machine. Furthermore, by using the cutting component 33 to automatically cut the processed hinge structure, the fully automated production of the hinge structure is achieved, thereby improving production efficiency.

[0090] Example 4:

[0091] This embodiment provides a rotary five-axis fully automatic hinge machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the displacement mechanism 5 includes:

[0092] Y-axis displacement assembly 50 is mounted on the worktable 2 and is used for the displacement of the feeding mechanism 6 on the Y-axis.

[0093] X-axis displacement assembly 51 is installed at the output end of Y-axis displacement assembly 50 and is used for the displacement of the feeding mechanism 6 on the X-axis.

[0094] Z-axis displacement assembly 52 is installed at the output end of X-axis displacement assembly 51 and is used for the displacement of the feeding mechanism 6 on the Z-axis.

[0095] Among them, the X-axis displacement assembly 51, Y-axis displacement assembly 50 and Z-axis displacement assembly 52 preferably adopt the combination of lead screw transmission mechanism and slide rail and slider, which will not be elaborated further here.

[0096] As can be seen from this embodiment, the five-axis linkage of the X-axis, Y-axis, Z-axis, feeding mechanism 6 and rotating tool holder 4 effectively ensures fully automatic cutting and forming of the hinge structure, thus effectively guaranteeing production efficiency and product quality.

[0097] Example 5:

[0098] This embodiment provides a rotary five-axis fully automatic hinge machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the feeding mechanism 6 includes:

[0099] Bracket 60 is installed at the output end of Z-axis displacement assembly 52;

[0100] The first clamping member 61 is slidably connected to the bracket 60;

[0101] The second clamping member 62 is mounted on the bracket 60 and is located on the side of the first clamping member 61 away from the Z-axis displacement assembly 52.

[0102] Pusher 63 is mounted on the side of bracket 60 and is used to push the first clamping member 61 to slide on bracket 60;

[0103] The first clamping member 61 includes a first cylinder and a first clamping mold installed at the output end of the pusher 63. The second clamping member 62 includes a second cylinder and a second clamping mold installed on the bracket 60. The first clamping mold includes a first fixed template installed at the output end of the pusher 63 and a first movable template installed at the output end of the first cylinder. The first movable template is located between the first fixed template and the pusher 63, that is, the first movable template passes through the first fixed template and connects to the output end of the first cylinder to form a scissor-type clamping. The second clamping mold includes a second fixed template installed on the bracket 60 and a second movable template installed at the output end of the second cylinder. The second movable template is located between the second fixed template and the pusher 63, that is, the second movable template passes through the second fixed template and connects to the output end of the second cylinder to form a scissor-type clamping. This improves the clamping effect between the first movable template and the first fixed template, as well as between the second movable template and the second fixed template, and enhances the clamping stability.

[0104] Meanwhile, the pusher 63 preferably adopts a screw drive mechanism and the cooperation of slide rail and slider, which will not be elaborated further here.

[0105] As can be seen from this embodiment, by using the pusher 63 to drive the first clamping member 61 to slide on the bracket 60, it is convenient to control the feeding amount of the blank. Specifically, after the previous product has completed the cutting process, the first clamping member 61 clamps the blank, the second clamping member 62 releases the blank, the pusher 63 pushes the first clamping member 61 to feed the blank, and then the second clamping member 62 clamps the blank, the first clamping member 61 releases the blank, and resets through the pusher 63. Therefore, the feeding length of the blank can be adjusted by the pushing distance of the pusher 63, which improves the convenience and accuracy of adjustment. When the pusher 63 has a full stroke, it is impossible to reach the required blank length. Multi-stage pushing can be used to meet the required blank length, that is, the above feeding steps are repeated until the required blank length is reached.

[0106] Example 6:

[0107] This embodiment provides a rotary five-axis fully automatic hinge machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and further includes:

[0108] A broken tool detection assembly is installed inside the frame 1 and is used to detect and stop a broken tool in the cutting mechanism 3.

[0109] Wear detection component, which is installed in the frame 1 and used to detect tool wear in the cutting mechanism 3 and to stop the machine.

[0110] As can be seen from this embodiment, by using a broken tool detection component, the machine can be stopped and an alarm can be issued in a timely manner after the cutting tool breaks, thereby effectively preventing the cutting process from continuing after the cutting tool breaks, producing defective products, and preventing the waste of blanks due to failure to detect it in time. On the other hand, by using a wear detection component, the machine can be stopped and an alarm can be issued in a timely manner after the cutting tool wears, effectively preventing the cutting process from continuing after the cutting tool wears, affecting product accuracy, and preventing an increase in the defect rate.

[0111] Example 7:

[0112] This embodiment provides a rotary five-axis fully automatic hinge machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the broken tool detection component includes:

[0113] The power supply is installed inside the frame 1 and forms a closed loop with the feeding mechanism 6 and the cutting mechanism 3;

[0114] The first sensor is installed inside the frame 1 and is used to detect the continuity of the closed loop.

[0115] The second sensor is installed inside the frame 1 and is used to detect whether the feeding mechanism 6 has reached the detection position;

[0116] Among them, workbench 2 is made of insulating material;

[0117] Meanwhile, the power supply is preferably low voltage and low current to improve safety, the first sensor is preferably a wire breakage sensor, the second sensor is preferably a position sensor, and the worktable 2 is preferably made of marble.

[0118] As can be seen in this embodiment, by using power discharge and the worktable 2 being made of insulating material, the cutting blade becomes the only conductive medium when cutting the blank on the feeding mechanism 6. Combined with the second sensor, it can promptly detect any blade breakage. Specifically, after the second sensor detects that the feeding mechanism 6 has delivered the blank to the processing point, it starts the power supply to discharge. At this time, the cutting blade cuts the blank, the closed loop is open, processing continues, and the power supply is turned off. However, if a blade breakage occurs during the cutting process, when cutting the next product, because the cutting blade is in a broken state, the second sensor detects that the feeding mechanism 6 has delivered the blank to the processing point and starts the power supply to discharge, breaking the closed loop. This controls the hinge machine to stop, preventing the cutting blade from continuing to cut after a breakage, thus avoiding the production of defective products. It also allows for timely detection, preventing waste of blanks. Furthermore, using insulating material for the worktable 2 prevents current from being conducted to the ground, ensuring the formation of a closed loop.

[0119] Example 8:

[0120] This embodiment provides a rotary five-axis fully automatic hinge machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the wear detection component includes:

[0121] The third sensor is installed inside the frame 1 and is connected in series with the second motor 310, the third motor 320, the fourth motor 330 and the fifth motor 300 in their respective circuits, and is used to detect the magnitude of the current in their respective circuits.

[0122] The third sensor is preferably a current sensor.

[0123] As can be seen from this embodiment, the current in the circuit controlling the motor is detected by the third sensor. When the cutting tool wears, the frictional resistance between it and the blank increases during cutting, which in turn leads to an increase in the torque of the motor. This causes the current in the motor circuit to increase, and the third sensor detects the increase in current, thus stopping the hinge machine to prevent further cutting after the cutting tool wears, which would affect product accuracy and prevent an increase in the defect rate.

[0124] Example 9:

[0125] This embodiment provides a rotary five-axis fully automatic hinge machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and further includes:

[0126] Limiting component 7 is mounted on the support plate 41 and is used to limit the rotation of the plate 40;

[0127] The limiting component 7 includes:

[0128] The bottom end of the limiting plate 70 and the support plate 41 has a mounting surface 71 for setting the limiting plate 70;

[0129] Limiting teeth 72 are disposed on the surface of the limiting disk 70 away from the axis.

[0130] The box body 73 has an opening on its top surface and a non-Newtonian fluid 74 inside. The limiting plate 70 extends into the box body, so that the limiting teeth 72 are immersed in the non-Newtonian fluid.

[0131] Reinforcing rib 75 is provided on the side of the box body 73;

[0132] Preferably, the limiting plate 70 and the support plate 41 are connected by bolts, the limiting tooth 72 and the limiting plate 70 are preferably integrated, and the mounting surface 71 and the surface of the support plate 42 are arranged parallel to each other.

[0133] As can be seen in this embodiment, by setting the limiting component 7, the impact force in the event of a tool collision is prevented from causing the plate 40 and support plate 41 to rotate, thereby preventing damage to the spindle of the indexer 43 or the first motor 44, avoiding damage or affecting the accuracy of the rotary tool holder 4 in adjusting the angle of the first cutting group 30, ensuring machining accuracy and extending service life. Specifically, the limiting tooth 72 and the non-Newtonian fluid 74 are used for limiting. When the rotary tool holder 4 is adjusted, the rotation speed is relatively slow, so the non-Newtonian fluid 74 will not have a limiting effect on the limiting tooth 72. It can improve the stability of the rotary tool holder 4 adjustment. When a collision occurs, the impact force brings a relatively fast speed. Therefore, the non-Newtonian fluid 74 will cooperate with the limiting tooth 72 to limit the support plate 41, prevent the support plate 41 from rotating, and avoid damage to the main shaft of the indexer 43 and the first motor 44 or the impact on the adjustment accuracy. Furthermore, the non-Newtonian fluid 74 will fit precisely with the limiting tooth 72, further improving the limiting effect on the support plate 41. Therefore, it can effectively avoid damage to the main shaft of the indexer 43 and the first motor 44 and the impact on their adjustment accuracy caused by a collision.

[0134] Example 10:

[0135] This embodiment provides a rotary five-axis fully automatic hinge machine. In addition to the technical solutions of the above embodiments, it also has the following technical features. The control method of the rotary five-axis fully automatic hinge machine includes the following steps:

[0136] S1: The rotating tool holder 4 is adjusted to a suitable angle according to the model of the product to be processed;

[0137] S2: The cutting mechanism 3 is started, the X-axis displacement assembly 51, the Y-axis displacement assembly 50 and the Z-axis displacement assembly 52 are started, and the feeding mechanism 6 and the blank on the feeding mechanism 6 are driven to move to the set processing position;

[0138] S3: The second clamping member 62 is released, and the first clamping member 61 clamps the blank and pushes the blank out of the set length by the pushing member 63;

[0139] S4: The second clamping member 62 clamps the blank, and the first clamping member 61 is released and reset by the pushing member 63;

[0140] S5: The cutting mechanism 3 processes the blank, and the tool breakage detection component and the wear detection component respectively detect the first cutting group 30, the second cutting group 31 and the third cutting group 32 during the processing, and determine whether there is tool breakage or wear.

[0141] S6: The first cutting group 30, the second cutting group 31 and the third cutting group 32 complete the processing of the blank, and the cutting component 33 cuts it to form the finished product, and repeats S3-S6;

[0142] In S5, the control steps for the broken tool detection component and the wear detection component include:

[0143] T1: The second sensor detects the position of the feeding mechanism 6 and determines whether the feeding mechanism 6 is in the set position. If not, the machine stops and an alarm is triggered. If yes, the process proceeds to T2.

[0144] T2: During the machining of the blank in the first cutting group 30, the second cutting group 31, and the third cutting group 32, the tool breakage and wear are detected.

[0145] ① Start the power supply and use the first sensor to detect the closed circuit and determine whether the closed circuit is open. If it is, stop the machine and issue an alarm. If not, turn off the power supply and continue processing.

[0146] ② The third sensor detects the current in its respective circuit and determines whether the current value exceeds the set value. If it does, the machine stops and an alarm is triggered; otherwise, processing and detection continue.

[0147] T3: After the blank is processed by the first cutting group 30, the second cutting group 31 and the third cutting group 32 respectively, repeat T1-T3.

[0148] As can be seen from this embodiment, the above control method enables fully automated processing of hinge structures and can adapt to the processing of hinge structures of different shapes, showing high applicability. At the same time, it can effectively detect broken or worn cutting tools, avoiding continued production under such conditions, which would lead to waste of raw materials and an increase in the defect rate.
