Description

Technical Field

[0001] The present application relates to the technical field of machining devices, and in particular to an automatic engraving and tapping device. Background Art

[0002] Machining generally refers to mechanical processing, including turning, cutting, planing, and tapping. Some workpieces are also engraved during the machining process for identification purposes. Existing engraving and tapping processes are performed using corresponding devices, and the two processes are carried out independently. After the engraving process is completed, the workpiece is manually moved to the tapping device for processing, resulting in relatively low processing efficiency. Utility Model Content

[0003] In order to achieve the continuity of the engraving and tapping processes and improve production efficiency, the present application provides an automatic engraving and tapping device.

[0004] The automatic engraving and tapping device provided in this application adopts the following technical solution:

[0005] An automatic engraving and tapping device, comprising:

[0006] A lettering device, comprising a first vibrating plate, a lettering mechanism connected to the first vibrating plate, and a material discharge box;

[0007] at least one tapping device; and

[0008] A conveying device, connecting the engraving device and the tapping device, the conveying device comprising a first lifting conveyor belt, an input conveyor belt connected to the first lifting conveyor belt, and an output conveyor belt, wherein the first lifting conveyor belt is connected to the discharge box;

[0009] Among them, the conveying device also includes at least one second vibrating disk, the second vibrating disk is connected to the tapping device, the input conveyor belt has at least one discharge port, and a material guiding mechanism for opening and closing the discharge port is provided in the input conveyor belt. The discharge port is above the second vibrating disk, and the output conveyor belt is connected to the tapping device.

[0010] By adopting the above technical solution, the workpiece is gradually transported from the first vibrating plate to the engraving mechanism and completes the engraving process. The workpiece that has completed the engraving process is output from the discharge box and passes through the first lifting conveyor belt in turn into the input conveyor belt. During the transmission of the input conveyor belt, the workpiece falls into the second vibrating plate through the discharge port. The second vibrating plate inputs the workpiece after engraving into the tapping device, and the workpiece that has completed tapping is output from the output conveyor belt, thereby realizing the automated continuous processing of the engraving and tapping processes and improving production efficiency.

[0011] Preferably, the material guiding mechanism includes:

[0012] A first driving member is installed at the input conveyor belt; and

[0013] A material guide plate connected to the first driving member and having one side thereof extending toward the material discharge port;

[0014] The guide plate has a first position for closing the discharge port and a second position for opening the discharge port; when the guide plate is in the second position, the conveying direction of the input conveyor belt is blocked.

[0015] By adopting this technical solution, as workpieces are conveyed along the input conveyor belt, the first drive element can drive the guide plate to move and divert the workpieces. When the discharge port is closed, the guide plate does not block the normal conveyance of the workpieces on the input conveyor belt. When the discharge port is opened, the guide plate blocks the conveying direction, and the workpieces are diverted along the guide plate out of the discharge port and into the second vibrating plate, enabling the input of the tapped workpieces. Secondly, the input conveyor belt can be connected to multiple tapping devices, enabling the simultaneous tapping of multiple workpieces, further improving production efficiency.

[0016] Preferably, the engraving device further comprises:

[0017] A pushing mechanism, comprising a second driving member and a limiting assembly connected to the second driving member; and

[0018] A mounting seat, wherein the mounting seat is provided with a character mold extending toward one side of the limiting component;

[0019] The discharge box has a discharge port, and the limiting assembly is driven by the second driving member to move away from or close to one side of the discharge port.

[0020] By adopting the above technical solution, the workpiece is output from the first vibration plate and enters the limiting assembly to achieve limiting. The limiting assembly is driven by the second driving member and pushed toward the side of the discharge port. During the process, the engraving process is completed after it collides with the mold on the mounting seat and is output from the discharge port.

[0021] Preferably, the engraving device further comprises:

[0022] The material guide seat is installed on the material discharge box, and the limiting component can slide relative to the material guide seat; wherein, the material guide seat has a material guide track surface for guiding the workpiece to slide, and the material guide track surface extends toward one side of the material discharge port.

[0023] By adopting the above technical solution, during the synchronous movement of the workpiece with the limit assembly, the workpiece can slide along the guide track surface of the guide seat and gradually extend toward the discharge port until the workpiece falls into the discharge port, making the connection between the entire engraving process and the discharge smoother.

[0024] Preferably, the tapping device comprises:

[0025] A rotating worktable, wherein the rotating worktable is provided with evenly distributed limiting openings in a circumferential direction, and the output section of the second vibration disk corresponds to the rotating worktable;

[0026] Tapping machine, placed above the rotary table; and

[0027] The locking mechanism includes a third driving member and a locking block connected to the third driving member; wherein the locking block is driven by the third driving member to move away from or toward one side of the limit opening.

[0028] By adopting the above technical solution, when the workpiece is input into the tapping device by the second vibrating disk, it enters the limit opening of the rotary worktable in advance, the locking mechanism locks the workpiece, and the tapping machine performs tapping operations on the locked workpiece. After completing the tapping of one workpiece, the rotary worktable rotates an angle to perform tapping operations on the next workpiece, thereby improving the continuity and reliability of the entire tapping process, further improving production efficiency.

[0029] Preferably, the tapping device further includes a material blocking assembly, which includes an output channel and a material blocking cylinder installed on one side of the output channel and capable of blocking the output channel, and one end of the output channel extends toward one side of the rotary workbench.

[0030] By adopting the above technical solution, when the workpiece is being tapped, the stop cylinder stops the workpiece after tapping. After tapping is completed, the stop cylinder resets the workpiece to unload the material, so that all workpieces on the rotary workbench can achieve the limitation of one tapping corresponding to one output, ensuring stable operation of the equipment.

[0031] Preferably, the locking mechanism further comprises:

[0032] base;

[0033] a swing arm, wherein both ends of the swing arm are hinged to the third driving member and the base respectively;

[0034] A sliding seat is slidably connected to the base, and the locking block is connected to the sliding seat; and

[0035] The driving arm has two ends hinged to the swing arm and the slide seat respectively.

[0036] By adopting the above technical solution, the lateral dimensions of the entire mechanism can be greatly reduced by utilizing a similar connecting rod swing arm structure, and the third drive member can be installed vertically. Secondly, the connecting rod swing arm structure also has good working stability, which can ensure the locking and positioning of the workpiece and the normal progress of the tapping process.

[0037] Preferably, an oil-spinning device is further included, and the oil-spinning device includes:

[0038] An oil slinger, wherein the delivery port of the oil slinger is connected to the output conveyor belt; and

[0039] A second lifting conveyor belt is provided, wherein the second lifting conveyor belt connects the tapping device and the oil thrower.

[0040] By adopting the above technical solution, the workpiece after the tapping process is output to the second lifting conveyor belt, and the workpiece is gradually input from the second lifting conveyor belt into the oil-stripping machine for the oil-stripping process, which can remove the lubricating medium on the surface of the workpiece due to the tapping process, and finally output it into the output conveyor belt for collection. The whole process is automated, saving the subsequent manual labor cost.

[0041] In summary, this application includes at least one of the following beneficial technical effects:

[0042] The engraving device and the tapping device are connected in series by the conveying device to realize the continuous development of the engraving and tapping processes and improve production efficiency. At the same time, the material guide mechanism set in the input conveyor belt is combined to realize the diversion of the workpiece and the input conveyor belt can be connected to multiple tapping devices to realize the synchronous tapping operation of multiple workpieces, further improving production efficiency.

[0051] The present application is further described in detail below with reference to the accompanying drawings.

[0052] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0054] Figure 1 The figure shows a structure of a workpiece 5 corresponding to an automatic engraving and tapping device according to this embodiment. The workpiece 5 includes a first surface 51 and a second surface 52 arranged vertically. A boss 53 is provided between the first and second surfaces 51, 52, forming a two-stage step-like structure. The workpiece 5 also has a threaded hole 54. The automatic engraving and tapping device 2 in this embodiment performs the engraving process on the first or second surface 51, 52, and simultaneously completes the tapping process on the threaded hole 54 of the workpiece 5.

[0055] See Figure 2 The automatic engraving and tapping device 2 includes an adjacent engraving device 1 and at least one tapping device 2. In this embodiment, three tapping devices 2 are arranged at intervals, and the three tapping devices 2 can perform tapping operations simultaneously. The conveying device 3 is used to realize the flow of the workpiece 5 between the engraving device 1 and the tapping device 2. The conveying device 3 includes a first lifting conveyor belt 31, an input conveyor belt 32 and an output conveyor belt 33 connected to each other. The input section of the first lifting conveyor belt 31 is connected to the engraving device 1 to receive the workpiece 5 after the engraving is completed. The first lifting conveyor belt 31 transfers the workpiece 5 to the input conveyor belt 32. The input conveyor belt 32 has a certain length to match the number of corresponding tapping devices 2. The longer the length of the input conveyor belt 32, the more workpiece 5 can be supplied to the tapping device 2, and more tapping devices 2 can be arranged. The workpiece 5 can be diverted in the input conveyor belt 32 and input into the tapping device 2.

[0056] The automatic engraving and tapping device 2 of this embodiment also includes an oil-spinning device 4, which receives the workpieces 5 after tapping. The workpieces 5 after oil-spinning are then collected on the output conveyor belt 33. The output conveyor belt 33 is the same length as the input conveyor belt 32 to match the number of corresponding tapping devices 2. The oil-spinning devices 4 correspond to the tapping devices 2 one by one. To ensure uniform output of the workpieces 5, the conveying device 3 also includes an output transition belt 34 connecting the oil-spinning device 4 and the output conveyor belt 33. Multiple output transition belts 34 merge into the output conveyor belt 33.

[0057] See Figure 3 , shows the structure of the lettering device 1, which mainly includes a first vibration disk 11 and a discharge box 12 located on one side. The output end of the first vibration disk 11 is located above the discharge box 12, and the discharge box 12 has a discharge port 121 and a discharge channel 122. The discharge box 12 is also equipped with a second driving member 13, a limiting assembly 16 connected to the second driving member 13, and a mounting seat 14. The side wall of the mounting seat 14 is provided with a corresponding font 15. The limiting assembly 16 is driven by the second driving member 13 to move toward or away from the discharge port 121. After the limiting assembly 16 passes through the font 15, the surface of the workpiece 5 is lettered. After the lettering is completed, the workpiece 5 is brought into the discharge box 12 by the discharge port 121 and output by the discharge channel 122. The discharge channel 122 is connected to the first lifting conveyor belt 31 to realize loading.

[0058] Combine Figure 4The limiting assembly 16 is mounted on a guide seat 17, which is slidably connected to a guide rail 18. The guide rail 18 is mounted on the body of the blanking box 12, thereby realizing the guided sliding of the limiting assembly 16. The limiting assembly 16 includes a number of guide wheels 161. Two guide wheels 161 are arranged as a group and arranged up and down. There is a gap between the two guide wheels 161 to form a limiting area 162. There is also a gap between the upper and lower groups of guide wheels 161. After being output by the first vibrating disk 11, the workpiece 5 enters the limiting assembly 16. The first surface 51 and the second surface 52 of the workpiece 5 are placed in the limiting area 162 and conflict with the guide wheel 161. The upper cover of the blanking box 12 is tilted so that the workpiece 5 is embraced by the limiting assembly 16 under the action of its own gravity. At the same time, due to the setting of the guide wheel 161, the workpiece 5 can rotate relative to the guide wheel 161.

[0059] Furthermore, the discharge box 12 is provided with a guide seat 19, one end of which extends into the gap between the upper and lower guide wheels 161, allowing the position limiting assembly 16 to slide relative to the guide seat 19. The guide seat 19 has a guide track surface 191. When the workpiece 5 is discharged, the outer surface of the boss 53 abuts the guide track surface 191 and is driven by the second drive member 13. The workpiece 5 can slide along the guide track surface 191. One end of the guide track surface 191 is generally arc-shaped and extends toward the discharge port 121. As the guide track surface 191 slides, the workpiece 5 gradually moves away from the position limiting assembly 16 and eventually disengages from the discharge port 121 and enters.

[0060] Joint Reference Figure 5 and Figure 6 The input conveyor belt 32 is also provided with a plurality of guide mechanisms, including a first drive member 35 and a guide plate 36 connected to the first drive member 35. A plurality of discharge ports 321 are provided on the side of the input conveyor belt 32. The guide plate 36 has a first position in which the discharge ports 321 are closed, driven by the first drive member 35, and a second position in which the discharge ports 321 are opened. When the guide plate 36 is in the second position, i.e., when the discharge ports 321 are open, the guide plate 36 is positioned within the input conveyor belt 32 and blocks the output direction X of the input conveyor belt 32. During the conveying process, the workpiece 5 is discharged from the discharge port 321 along the guide plate 36, thereby diverting the workpiece 5. The conveying device 3 includes a second vibrating plate 37 positioned below the discharge port 321. The workpiece 5 discharged from the discharge port 321 falls into the second vibrating plate 37. The output end of the second vibrating plate 37 is connected to the tapping device 2 to achieve tapping supply. The start signal of the first driving member 35 can be a workpiece 5 detection sensor on the second vibration disk 37. When the workpiece 5 placed in the second vibration disk 37 is less than the threshold of the sensor, the first driving member 35 is actuated to open the discharge port 121 to realize the replenishment of the workpiece 5.

[0061] Combine Figure 7The tapping device 2 includes a rotary table 22, a tapping machine 21, and a locking mechanism 23. The tapping machine 21 is placed above the rotary table 22, and the locking mechanism 23 is located on one side of the rotary table 22. The rotary table 22 can be driven by a servo motor to achieve intermittent rotation with a limited rotation angle, or it can use a ratchet structure to achieve intermittent rotation.

[0062] The rotating workbench 22 is provided with a plurality of circumferentially evenly distributed limiting openings 221. After being output by the second vibration disk 37, the workpiece 5 slides into the limiting opening 221. The locking mechanism 23 locks and fixes the workpiece 5 from the open side of the limiting opening 221, and then the workpiece 5 is limited in the limiting opening 221. The tapping machine 21 is actuated to realize the tapping process.

[0063] The tapping device 2 also includes an output channel 24, one end of which is adjacent to the rotary workbench 22. The workpiece 5 after tapping can enter the output channel 24 for output, and the other end of the output channel 24 is connected to the oil-throwing device 4. The oil-throwing device 4 includes a second lifting conveyor belt 41 and a connected oil-throwing machine 42. The output channel 24 is connected to the second lifting conveyor belt 41. The workpiece 5 after tapping is conveyed by the second lifting conveyor belt 41 to the oil-throwing machine 42 for oil-throwing operation. After oil-throwing is completed, it is conveyed by the output transition belt 34 to the output conveyor belt 33 to complete the processing of the workpiece 5.

[0064] To ensure stable tapping of the workpiece 5 , a stopper cylinder 25 is provided on the output channel 24 . The piston rod of the stopper cylinder 25 can block the output channel 24 . When the workpiece 5 is tapping, the stopper cylinder 25 blocks the output channel 24 .

[0065] The locking mechanism 23 includes a third driving member 231, a swing arm 232, a driving arm 233, a slide 235 and a locking block 236. The slide 235 can slide relatively on the base 234. The base 234 is set on the workbench of the tapping device 2. The locking block 236 is connected to the slide 235. A groove is provided at the end of the locking block 236, and the groove can fit with the surface of the workpiece 5.

[0066] The two ends of the swing arm 232 are respectively hinged to the third driving member 231 and the base 234, and the two ends of the driving arm 233 are respectively hinged to the slide 235 and the swing arm 232, so that the third driving member 231, the swing arm 232 and the driving arm 233 form a connecting rod structure. The direction of the force of the third driving member 231 can form an angle with the force of the driving arm 233, thereby reducing the installation space in the horizontal direction.

[0067] When the device is processing the workpiece 5, the workpiece 5 is pre-introduced into the first vibrating disk 11. As the first vibrating disk 11 works, the workpiece 5 is gradually output and falls into the limiting assembly 16. The limiting assembly 16 is driven by the second driving member 13 to move toward the side of the discharge port 121. During the movement, the workpiece 5 passes through the mold 15 to complete the lettering process and is output. The output workpiece 5 is conveyed to the input conveyor belt 32 by the first lifting conveyor belt 31, and the guide mechanism is used to realize the diversion of the workpiece 5. The diverted workpiece 5 enters the second vibrating disk 37 and is input into the tapping device 2 by the second vibrating disk 37. After the tapping is completed, it is output to the oil-stripping device 4 for oil-stripping, and finally collected uniformly by the output conveyor belt 33. The entire device realizes the automated processing of lettering, tapping and oil-stripping of the workpiece 5, thereby improving production efficiency.

[0068] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
