Abstract
Description
Technical Field
[0001] This invention belongs to the field of handle processing technology, and in particular relates to an automated device for drilling and tapping handles. Background Technology
[0002] In the lock industry, a handle (also known as a lever or pull handle) is the part of a lock used to manually operate the bolt. It is usually installed on the inside or outside of a door and is used to control the opening and closing of the lock by rotating, pressing down, or pulling.
[0003] The production process of handles involves die casting, drilling, tapping, and other steps. Currently, each step is performed on separate equipment. After completing one step, the handle needs to be transferred to another piece of equipment. This means that workers need to manually position and clamp the handle for each step, which is time-consuming, labor-intensive, and results in low production efficiency. Therefore, in order to improve the production efficiency of handles, it is necessary to improve the existing handle processing methods. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned technical problems by providing an automated drilling and tapping device with a lever handle. This automated device integrates the drilling station, tapping station, and operation station onto a rotary automated device, enabling continuous automated processing of multiple processes. Compared to the traditional single-machine step-by-step processing method, it reduces the transfer time of workpieces between different devices and significantly improves production efficiency.
[0005] In view of this, the present invention provides an automated device for drilling and tapping with a lever, comprising:
[0006] The machine frame is equipped with a turntable, and at least three positioning elements are spaced apart along the circumference of the turntable. The positioning elements can initially position the workpiece. The turntable can rotate relative to the machine frame and drive all the positioning elements to switch sequentially between the operating station, the drilling station and the tapping station. Loading and unloading operations are performed at the operating station.
[0007] The drilling mechanism is set at the drilling station and can drill holes in the workpiece located on the positioning part at the drilling station.
[0008] Tapping mechanism, set in tapping station, can tap the workpiece on the positioning part located at the tapping station;
[0009] Two sets of clamping components are respectively set at the drilling station and the tapping station. The clamping components can be close to the positioning components to clamp the workpiece at the drilling station or the tapping station, and the clamping components can be far away from the positioning components to release the workpiece.
[0010] In this technical solution, the worker places the workpiece to be processed on the positioning component at the operating station. The turntable switches the positioning component carrying the workpiece from the operating station to the drilling station. At the drilling station, the clamping component cooperates with the positioning component to clamp the workpiece. At this time, the position on the workpiece that needs to be drilled is opposite to the position of the drilling mechanism. The drilling mechanism performs drilling on the workpiece. After drilling is completed, the clamping component moves away from the positioning component and releases the workpiece. Then, the turntable switches the positioning component carrying the drilled workpiece from the drilling station to the tapping station. At the tapping station, the clamping component cooperates with the positioning component to clamp the workpiece. At this time, the position on the workpiece that needs to be tapped is opposite to the position of the tapping mechanism. The tapping mechanism performs tapping on the workpiece. After tapping is completed, the clamping component moves away from the positioning component and releases the workpiece. Then, the turntable switches the positioning component carrying the drilled and tapped workpiece from the tapping station to the operating station. At the operating station, the worker removes the processed workpiece, completing the processing of one workpiece.
[0011] In the above technical solution, the positioning component further includes a fixed base, a head positioning block, and a tail positioning block. The fixed base is mounted on the turntable, and both the head positioning block and the tail positioning block are mounted on the fixed base. A space is formed between the head positioning block and the fixed base, allowing the tail end of the workpiece to pass through radially along the turntable. The head positioning block can position the head of the workpiece, and the tail positioning block can position the tail end of the workpiece.
[0012] In the above technical solution, the clamping component further includes a clamping plate and a clamping cylinder. The clamping cylinder can drive the clamping plate to move closer to or away from the head positioning block along the radial direction of the turntable. Grooves are provided on the side walls of the clamping plate and the head positioning block that are close to each other. The grooves are adapted to the outer contour of the head of the workpiece.
[0013] In the above technical solution, the operating station further includes a loading station and a unloading station. The turntable can drive all the positioning parts to switch sequentially between the loading station, drilling station, tapping station and unloading station. The loading station is equipped with a loading mechanism, which can push a workpiece onto the positioning part at the loading station each time and complete the initial positioning. The unloading station is equipped with an unloading mechanism, which can push the workpiece on the positioning part at the unloading station away from the positioning part along the turntable radially.
[0014] In the above technical solution, the feeding mechanism further includes:
[0015] A storage ramp allows multiple workpieces to be stacked sequentially along the width of the workpieces, and the workpieces can leave the storage ramp from the bottom.
[0016] The placement table is located below the bottom of the storage slope. A stop seat is provided on the side of the placement table away from the storage slope. The stop seat can block the workpiece from falling off the bottom of the storage slope. A mating seat is provided on the side of the stop seat close to the storage slope. The distance between the mating seat and the stop seat is adapted to the width of the workpiece.
[0017] The pusher seat is slidably mounted on the display table along the radial direction of the turntable. During its movement, the pusher seat passes through the space between the stop seat and the mating seat. The pusher seat can push the workpiece on the display table onto the positioning part at the loading station.
[0018] The stop bar is located above the pusher seat. The connecting end of the stop bar is rotatably connected to the stop seat. When the free end of the stop bar is in the open position, it allows the workpiece to enter the swing table. When the free end of the stop bar is in the blocking position, it prevents the workpiece from leaving the storage slope.
[0019] The material pusher mechanism can drive the material pusher seat to slide back and forth on the swaying platform, and drive the stop bar to swing between the open position and the blocking position.
[0020] In the above technical solution, the pushing drive mechanism further includes:
[0021] A rack is connected to a pusher seat, and multiple teeth on the rack are distributed along the sliding direction of the pusher seat;
[0022] The driving gear is rotatably mounted on the display platform and meshes with the rack.
[0023] The material pushing power source can drive the drive gear to rotate;
[0024] The drive gear and the rotating shaft at the connection end of the drive gear and the stop bar are coaxially distributed. A pusher is provided on the end face of the drive gear near the stop bar. The pusher can push the stop bar from the blocking position to the guiding position during the movement of the drive gear.
[0025] The reduction gear set has its input end connected to the driving gear and its output end connected to the drive gear.
[0026] The elastic element is set on the display platform and is connected to the stop rod. When the stop rod is in the blocking position, the elastic element is in a relaxed state. When the stop rod is in the open position, the elastic element is squeezed and deformed.
[0027] In the above technical solution, further, when the pusher seat is in the initial position, the position connection between the two ends of the drive gear and the rack is established, and at this time the pusher is not in contact with the stop bar; during the process of the pusher seat sliding away from the initial position to the direction away from the positioning component, the pusher pushes the stop bar from the blocking position to the guiding position; thereafter, during the process of the pusher seat sliding towards the positioning component, the pusher moves away from the stop bar.
[0028] In the above technical solution, the feeding mechanism further includes:
[0029] The mounting bracket is installed on the machine frame.
[0030] The feeding cylinder is mounted on a fixed frame and is located on the side of the positioning component near the axis of the turntable. The output rod of the feeding cylinder can move closer to or further away from the positioning component in the radial direction of the turntable.
[0031] The feeding block is connected to the output rod of the feeding cylinder. During its movement, the feeding block can push the workpiece on the positioning component away from the positioning component.
[0032] In the above technical solution, furthermore, a feeding ramp is provided on the side of the positioning component away from the feeding cylinder, and the top of the feeding ramp is lower than the surface of the workpiece placed on the positioning component in the vertical direction.
[0033] This invention also discloses a method of using the aforementioned automated equipment, which includes the following steps:
[0034] Loading steps: The turntable switches a positioning part without a workpiece to the loading station. The pusher power source drives the drive gear to rotate and drives the pusher seat to slide away from the positioning part from the initial position, causing the stop bar to swing from the blocking position to the open position. At this time, a workpiece enters the placement table. Then, the pusher power source drives the drive gear to rotate and drives the pusher seat to slide closer to the positioning part from the current position, causing the stop bar to swing from the open position to the blocking position. After the pusher seat pushes the workpiece onto the positioning part at the loading station, the pusher power source drives the drive gear to rotate and drives the pusher seat to return from the current position to the initial position, completing one loading operation.
[0035] Drilling steps: The turntable switches a positioning piece carrying the workpiece to the drilling station. Then, the clamping piece at the drilling station cooperates with the corresponding positioning piece to clamp the workpiece. Then, the drilling mechanism drills the workpiece on the positioning piece at the drilling station. After drilling is completed, the clamping piece at the drilling station moves away from the corresponding positioning piece.
[0036] Tapping steps: The rotary table switches a positioning piece carrying the completed drilling to the tapping station. Then, the clamping piece at the tapping station cooperates with the corresponding positioning piece to clamp the workpiece. The tapping mechanism then performs tapping on the workpiece on the positioning piece at the tapping station. After tapping is completed, the clamping piece at the tapping station moves away from the corresponding positioning piece.
[0037] Unloading steps: The turntable switches a positioning part carrying tapped parts to the unloading station, and the unloading mechanism pushes the workpiece on the positioning part at the unloading station away from the positioning part;
[0038] The loading, drilling, tapping, and unloading steps can be performed simultaneously.
[0039] The beneficial effects of this invention are:
[0040] 1. By integrating drilling, tapping, and operation stations onto a rotary automated machine, continuous automated processing of multiple processes is achieved. Compared to traditional single-machine step-by-step processing, this reduces the workpiece transfer time between different devices, significantly improving production efficiency; furthermore, it eliminates the need for manual repetitive positioning and clamping, reducing the labor intensity of workers, avoiding human error, and improving processing consistency.
[0041] 2. By optimizing the operating station into a loading station and a unloading station, a loading mechanism is set up at the loading station to automatically load the workpiece, and a unloading mechanism is set up at the unloading station to automatically unload the workpiece, reducing the number of manual operation steps and further improving production efficiency.
[0042] 3. By designing the feeding mechanism as a combination of a storage ramp, a placement platform, a stop seat, a mating seat, a pusher seat, a stop rod, and a pusher drive mechanism, the pusher seat can push one workpiece onto the corresponding positioning part at a time under the drive of the pusher drive mechanism. The stop rod can guide or block the bottom of the storage ramp as needed. This can achieve orderly feeding and avoid feeding failure caused by multiple workpieces stacking vertically.
[0043] 4. By designing the pusher drive mechanism as a combination of rack, drive gear, pusher power source, drive gear, pusher column, reduction gear set and elastic element, when the pusher pushes the workpiece to the positioning part, the stop rod moves synchronously to block subsequent workpieces, avoiding double material or jamming. Furthermore, the movement of the pusher and the movement of the stop rod form a mistake-proof mechanism design, ensuring that new workpieces are allowed to enter only when the pusher retracts, while blocking other workpieces in the storage slope during push, fundamentally eliminating the problem of multiple material overlap.

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0061] In the description of this invention, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments of the invention. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0062] The handle structure of the present invention is as follows Figure 1 As shown, the handle is L-shaped, consisting of a handle portion G1 and a handle head G2. The drilling and tapping holes are located in the handle head G2. Figure 1 The upper center shows the handle to be processed. In some cases, a shallow groove can be pre-machined at the drilling location of workpiece G. Figure 1 The lower center shows the handle after drilling and tapping. The automated equipment in this invention mainly performs drilling and tapping on the handle head G2.
[0063] Example 1
[0064] This embodiment provides an automated device for drilling and tapping with a lever, including: a frame 1, a turntable 2, multiple positioning components 3, a drilling mechanism 4, a tapping mechanism 5, and two sets of clamping components 6;
[0065] Please see Figure 1 and Figure 2 A turntable 2 is mounted on the frame 1, and the turntable 2 can rotate relative to the frame 1. Please refer to [link / reference]. Figure 4 A switching power source 201 for driving the turntable 2 to rotate is provided at the bottom of the frame 1. The switching power source 201 can be a combination of a servo motor and a reducer to achieve precise angle switching of the turntable 2. The control method of pausing after rotating the turntable 2 at a certain angle has been implemented in the field and will not be described in detail here.
[0066] Multiple positioning elements 3 are spaced apart along the circumference of the turntable 2. The positioning elements 3 can perform preliminary positioning of the workpiece G. For an example, please refer to [link to example]. Figure 7 The positioning component 3 includes a fixed base 301, a head positioning block 302, and a tail positioning block 303. The fixed base 301 is mounted on the turntable 2, and the fixed base 301 and the turntable 2 can be detachably connected. The head positioning block 302 and the tail positioning block 303 are both mounted on the fixed base 301. A space is formed between the head positioning block 302 and the fixed base 301, allowing the tail end of the workpiece G to pass radially along the turntable 2. A groove is provided on the side wall of the head positioning block 302 away from the tail positioning block 303. The groove is adapted to the outer contour of the head of the workpiece G. The transverse cross section can be V-shaped, arc-shaped, etc. The head of the workpiece G can be inserted into the groove to achieve positioning of the head of the workpiece G; there are two sets of tail positioning blocks 303, and the two sets of tail positioning blocks 303 are distributed at intervals along the width direction of the workpiece G. The space between the two sets of tail positioning blocks 303 is adapted to the width of the workpiece G. After the tail end of the workpiece G passes through the space between the head positioning block 302 and the fixed seat 301, it can enter the space between the two sets of tail positioning blocks 303, so that the workpiece G is limited in the width direction, thereby achieving positioning of the tail end of the workpiece G.
[0067] Preferably, the head positioning block 302 is detachably connected to the fixed base 301, and the positions of the two sets of tail positioning blocks 303 on the width of the workpiece G are adjustable, so as to adapt to workpieces G of different widths.
[0068] Turntable 2 can drive all positioning components 3 to switch sequentially between the operating station, drilling station and tapping station. For example, positioning component 3 can switch from the operating station to the drilling station, then from the drilling station to the tapping station, and finally from the tapping station back to the operating station. At the operating station, workers can perform loading and unloading operations.
[0069] The drilling mechanism 4 is set at the drilling station, and the drilling mechanism 4 can perform drilling on the workpiece G on the positioning part 3 located at the drilling station.
[0070] The tapping mechanism 5 is set at the tapping station, and the tapping mechanism 5 can perform tapping processing on the workpiece G on the positioning part 3 located at the tapping station.
[0071] In this embodiment, both the drilling mechanism 4 and the tapping mechanism 5 include a stand, a lifting structure, a mounting base, a processing power source, and a cutting tool. The stand is mounted on the frame 1, and the lifting structure is mounted on the stand. The lifting structure can drive the mounting base to move vertically. The processing power source and the cutting tool are both mounted on the mounting base. The processing power source can be a combination of a motor and a reducer. The processing power source can drive the cutting tool to rotate and process the workpiece G. In the drilling mechanism 4, the cutting tool is a drill bit, and in the tapping mechanism 5, the cutting tool is a tap. For example, the lifting structure can be a combination of a lead screw, a nut, and a motor. The lead screw is mounted on the stand, and the motor is used to drive the lead screw to rotate. The nut is set on the mounting base, and the mounting base is vertically slidably connected to the stand. The mounting base is connected to the lead screw through the nut, thereby realizing the lifting of the mounting base.
[0072] Two sets of clamping members 6 are respectively set at the drilling station and the tapping station. The clamping members 6 can approach the positioning member 3 to clamp the workpiece G at the drilling station or the tapping station, and the clamping members 6 can move away from the positioning member 3 to release the workpiece G.
[0073] For example, please refer to Figure 7 The clamping component 6 includes a clamping plate 601 and a clamping cylinder 602. The clamping cylinder 602 is installed on the upright of the corresponding workstation. The clamping cylinder 602 is connected and cooperates with the air supply equipment available on the market, which can drive the clamping plate 601 to move closer to or away from the head positioning block 302 along the radial direction of the turntable 2. The side wall of the clamping plate 601 near the head positioning block 302 is also provided with a groove. This groove cooperates with the groove on the head positioning block 302, so that when the clamping plate 601 is close to the head positioning block 302, it can finally position the workpiece G through the two grooves and clamp the workpiece G by cooperating with the head positioning block 302. When the clamping plate 601 is away from the workpiece G, it will not interfere with the turntable 2 to switch the workstation of the positioning component 3 carrying the workpiece G.
[0074] In this embodiment, the worker places the workpiece G to be processed on the positioning member 3 at the operating station. The turntable 2 switches the positioning member 3 carrying the workpiece G from the operating station to the drilling station. At the drilling station, the clamping member 6 cooperates with the positioning member 3 to clamp the workpiece G. At this time, the position on the workpiece G that needs to be drilled is opposite to the position of the drilling mechanism 4. The drilling mechanism 4 performs drilling on the workpiece G. After drilling is completed, the clamping member 6 moves away from the positioning member 3 to release the workpiece G. Then, the turntable 2 moves the positioning member 3 carrying the drilled workpiece G from the operating station. The drilling station is switched to the tapping station. In the tapping station, the clamping part 6 and the positioning part 3 cooperate to clamp the workpiece G. At this time, the position on the workpiece G that needs to be tapped is opposite to the position of the tapping mechanism 5. The tapping mechanism 5 performs tapping on the workpiece G. After the tapping is completed, the clamping part 6 moves away from the positioning part 3 to release the workpiece G. Then the turntable 2 switches the positioning part 3, which carries the workpiece G after drilling and tapping, from the tapping station to the operation station. In the operation station, the worker removes the finished workpiece G, thus completing the processing of one workpiece G.
[0075] In this embodiment, at least three positioning elements 3 are provided. When one positioning element 3 is located at the operating station, one positioning element 3 is located at the drilling station and one positioning element 3 is located at the tapping station. In this way, after a period of time since production started, when the worker is loading or unloading materials at the operating station, the drilling station is simultaneously performing drilling and the tapping station is simultaneously performing tapping, thereby enabling continuous production and improving production efficiency.
[0076] In this embodiment, the switching of the workstation of the turntable 2 to the positioning component 3, and the operation control of the drilling mechanism 4 and the tapping mechanism 5 are all controlled by the control box to realize automated processing. The control box is set on the frame 1.
[0077] In addition, cutting fluid can be sprayed onto the machining area during drilling and tapping processes to provide good cooling and lubrication.
[0078] Example 2
[0079] Based on Example 1, this embodiment further optimizes the structure of the automated equipment;
[0080] The operating station includes a loading station and a unloading station. The turntable 2 can drive all the positioning parts 3 to switch sequentially between the loading station, drilling station, tapping station and unloading station. The loading station is equipped with a loading mechanism 7, which can push a workpiece G onto the positioning part 3 at the loading station each time and complete the initial positioning. The unloading station is equipped with an unloading mechanism 8, which can push the workpiece G on the positioning part 3 at the unloading station radially away from the positioning part 3 along the turntable 2.
[0081] Please see Figure 1 and Figure 2In this embodiment, at least four positioning elements 3 are provided. When there is one positioning element 3 at the loading station, there is one positioning element 3 at the drilling station, the tapping station, and the unloading station, which enables continuous production.
[0082] Please see Figure 5 and Figure 6 At the start of production, the loading mechanism 7 pushes a workpiece G onto the positioning piece 3 at the loading station. The loading mechanism 7 can push the workpiece G radially along the turntable 2, so that the workpiece G can cooperate with the head positioning block 302 and the tail positioning block 303 to perform preliminary positioning of the workpiece G. Then, the turntable 2 switches the positioning piece 3 carrying the workpiece G to the drilling station for drilling. Then, the turntable 2 switches the positioning piece 3 carrying the drilled workpiece G to the tapping station for tapping. Finally, the turntable 2 switches the positioning piece 3 carrying the drilled and tapped workpiece G to the unloading station. The unloading mechanism 8 pushes the workpiece G away from the positioning piece 3 at the unloading station. After a period of production, the four stations can be operated simultaneously to achieve continuous production processing.
[0083] Example 3
[0084] Based on Embodiment 2, this embodiment also discloses a structure of the feeding mechanism 7;
[0085] In this embodiment, the feeding mechanism 7 includes: a storage inclined surface 701, a display platform 702, a pusher seat 705, a stop bar 706, and a pusher drive mechanism 9;
[0086] Please see Figure 8 Multiple workpieces G can be stacked sequentially along the width direction of the workpiece G on the storage inclined surface 701. Workpieces G can leave the storage inclined surface 701 from the bottom. To prevent multiple workpieces G from being stacked longitudinally on the storage inclined surface 701, a baffle is also provided on the storage inclined surface 701 to limit the movable height of the workpieces G. Figure 5 and Figure 6 The diagram shows multiple workpieces G stored on the storage ramp 701. In actual production, the length of the storage ramp 701 can be larger, and the workpieces G on the storage ramp 701 can be transferred from the previous process to the storage ramp 701.
[0087] The display stand 702 is mounted on the rack 1, and is located below the bottom of the storage ramp 701. Please refer to [link / reference]. Figure 8 and Figure 9A stop seat 703 is provided on the side of the display table 702 away from the storage slope 701. The stop seat 703 can block the workpiece G from detaching from the bottom of the storage slope 701. A mating seat 704 is provided on the side of the stop seat 703 close to the storage slope 701. The distance between the mating seat 704 and the stop seat 703 is adapted to the width of the workpiece G. In order to enable the workpiece G to smoothly enter the space between the stop seat 703 and the mating seat 704, an inclined surface can be machined on the top of the side wall of the stop seat 703 close to the mating seat 704. At the same time, an inclined surface can be machined on the top of the side wall of the mating seat 704 close to the stop seat 703.
[0088] Please see Figure 8 and Figure 10 The display table 702 is provided with a slide groove, and the pusher seat 705 is slidably connected to the slide groove along the radial direction of the turntable 2. The pusher seat 705 is located on the display table 702. During the movement, the pusher seat 705 passes through the space between the stop seat 703 and the mating seat 704. The pusher seat 705 can push the workpiece G on the display table 702 to the positioning part 3 at the loading station.
[0089] Please see Figure 8 and Figure 9 The stop rod 706 is located above the pusher seat 705. The movement of the stop rod 706 will not interfere with the movement of the pusher seat 705. The two ends of the stop rod 706 are defined as the connecting end and the free end, respectively. The connecting end of the stop rod 706 is rotatably connected to the stop seat 703, allowing the free end of the stop rod 706 to swing about the rotation center of the connecting end. When the free end of the stop rod 706 swings to the point where the sliding direction of the entire stop rod 706 is the same as that of the pusher seat 705, the stop rod 706 is in the conducting position, allowing the workpiece G to enter the swing table 702. When the free end of the stop rod 706 swings to the bottom near the storage slope 701, such as Figure 10 As shown, the stop bar 706 is in the blocking position, which can prevent the workpiece G from leaving the storage inclined surface 701;
[0090] The pusher drive mechanism 9 can drive the pusher seat 705 to slide back and forth on the display table 702, and drive the stop rod 706 to swing between the open position and the blocking position.
[0091] In this embodiment, the material pushing drive mechanism 9 includes: rack 901, drive gear 902, material pushing power source 903, drive gear 904, reduction gear set 10, and elastic element 11.
[0092] Please see Figure 9The display stand 702 is in the shape of an inverted U. The rack 901 is located below the display stand 702. Multiple teeth on the rack 901 are distributed along the sliding direction of the pusher seat 705. The bottom of the pusher seat 705 passes through the slide groove and connects with the rack 901. When the rack 901 moves, it will move the pusher seat 705 together.
[0093] Please see Figure 9 The drive gear 902 is rotatably mounted on the display platform 702, and is meshed with the rack 901. The pusher power source 903 drives the drive gear 902 to rotate. The pusher power source 903 can be a combination of a servo motor and a reducer, and can be mounted on the frame 1. Figure 9 As shown, the pusher power source 903 can also be installed in the stop seat 703, in which case the stop seat 703 is designed with an internal mounting groove.
[0094] Please see Figure 8 and Figure 9 The rotating shafts of the drive gear 904 and the stop bar 706 are coaxially distributed. A push post 905 is provided on the end face of the drive gear 904 near the stop bar 706. The push post 905 can push the stop bar 706 from the blocking position to the guiding position during the movement of the drive gear 904.
[0095] Please see Figure 9 The input end or input gear of the reduction gear set 10 is connected to the driving gear 902, and the output end or output gear of the reduction gear set 10 is connected to the driving gear 904. The reduction gear set 10 can be a reduction structure formed by multiple gears in the prior art. The reduction gear set 10 can reduce the rotational speed of the driving gear 902 and transmit it to the driving gear 904. This means that when the driving gear 902 rotates multiple times, the driving gear 904 will only rotate half a turn or one turn. Furthermore, if the driving gear 904 and the driving gear 902 need to rotate in opposite directions, the reduction gear set 10 also needs to have the function of changing the rotational direction. This can be achieved by simply meshing one more gear between the output gear of the reduction gear set 10 and the driving gear 904.
[0096] Please see Figure 10 The elastic element 11 is set on the display table 702 or the stop seat 703. The elastic element 11 is connected to the stop rod 706. When the stop rod 706 is in the blocking position, the elastic element 11 is in the relaxed state. The elastic element 11 can be selected from the existing technology such as torsion spring and compression spring. The elastic element 11 has a certain rigidity, so that in the natural state, the elastic element 11 can block multiple workpieces G on the storage slope 701. When the stop rod 706 is in the conducting position, the elastic element 11 is squeezed and deformed.
[0097] In this embodiment, when the pusher seat 705 is in the initial position, the positions of the drive gear 902 and the two ends of the rack 901 are connected, which means that the rack 901 can move in two directions at this time. At this time, the pusher 905 is not in contact with the stop rod 706, or the pusher 905 is just in contact with the stop rod 706 and no external force is applied to the stop rod 706. During the process of the pusher seat 705 sliding away from the initial position to the direction away from the positioning member 3, the pusher 905 pushes the stop rod 706 from the blocking position to the conduction position. After that, during the process of the pusher seat 705 sliding towards the direction of the positioning member 3, the pusher 905 moves away from the stop rod 706.
[0098] In this embodiment, the feeding mechanism 7 can decompose the feeding of workpiece G into three stages;
[0099] Please refer to the first stage of feeding. Figure 11 , Figure 11 The left side shows a schematic of the pusher seat 705 in its initial position, with the stop rod 706 in the blocking position. When the drive gear 902 rotates clockwise, driving the rack 901 to move away from the positioning member 3, the drive gear 902 drives the drive gear 904 to rotate counterclockwise through the reduction gear set 10. During this process, the push column 905 pushes the free end of the stop rod 706 to swing counterclockwise, causing the stop rod 706 to swing from the blocking position to the conducting position. At the same time, the elastic member 11 is compressed and deformed, resulting in... Figure 11 The diagram on the right shows that at this time, the workpiece G on the storage slope 701 comes to the placement table 702 through the bottom of the storage slope 701. At this time, the head of the workpiece G on the placement table 702 can block other workpieces G on the storage slope 701.
[0100] Please refer to the second stage of feeding. Figure 12 After a workpiece G arrives on the placement table 702, as follows Figure 12 As shown in the diagram on the left, the drive gear 902 rotates counterclockwise, causing the rack 901 to move closer to the positioning member 3. The drive gear 902, through the reduction gear set 10, drives the drive gear 904 to rotate clockwise. During this process, the push post 905 gradually moves away from the stop rod 706, while the stop rod 706, pushed by the elastic member 11, remains in contact with the push post 905 until the stop rod 706 reaches the blocking position, thus achieving... Figure 12 As shown on the right, at this time, the free end of the stop rod 706 blocks the workpiece G on the storage inclined surface 701. As the rack 901 continues to move towards the positioning member 3 to push the workpiece G onto the positioning member 3, the push column 905 has already separated from the stop rod 706 and will not affect the stop rod 706. When the workpiece G has been pushed onto the positioning member 3, the push column 905 will not contact the other side wall of the stop rod 706.
[0101] Please refer to the third stage of feeding. Figure 13 After the pusher seat 705 pushes the workpiece G onto the positioning part 3, as Figure 13 As shown in the diagram on the left, the drive gear 902 rotates clockwise, causing the rack 901 to move away from the positioning member 3. The drive gear 902 drives the drive gear 904 to rotate counterclockwise through the reduction gear set 10. During this process, the pusher 905 gradually approaches the stop rod 706. When the pusher 705 returns to the initial position, the drive gear 902 stops rotating. At this time, the pusher 905 is not in contact with the stop rod 706 or just in contact with the stop rod 706, and will not push the stop rod 706.
[0102] Each feeding operation of the feeding mechanism 7 completes an operation from the first stage to the third stage.
[0103] In this embodiment, the pusher seat 705 is driven to move linearly by the cooperation of gears and racks 901, resulting in high transmission accuracy. The rotational force of the drive gear 902 is transmitted to the drive gear 904 through the reduction gear set 10. Then, the push column 905 on the drive gear 904 cooperates with the elastic element 11 to control the position switching of the stop rod 706. In this way, the sequential operation of the feeding mechanism 7 for feeding, pushing and stopping is improved through pure mechanical transmission, resulting in a low failure rate and suitability for high-frequency continuous operation.
[0104] Furthermore, the elastic element 11 is in its natural state when the stop bar 706 is in the blocking position, and is only compressed when it is in the conducting position, which reduces the long-term stress loss of the elastic element 11 and extends its service life. Moreover, since the elastic element 11 is in its natural state when the stop bar 706 is in the blocking position, when it is necessary to disassemble and repair the pusher seat 705 or the reduction gear set 10, the workpiece G can be present on the storage slope 701. That is to say, it is permissible to temporarily suspend the equipment during the processing to perform the above disassembly and repair operations without first removing the workpiece G from the storage slope 701. In this way, production can start immediately after the disassembly and repair operations are completed, saving the time of unloading and loading on the storage slope 701, and further improving production efficiency.
[0105] Example 4
[0106] Based on Embodiment 2, this embodiment also discloses a structure of the feeding mechanism 8;
[0107] In this embodiment, the feeding mechanism 8 includes: a fixed frame 801, a feeding cylinder 802, a feeding block 803, and a feeding inclined surface 804;
[0108] Please see Figure 3 or Figure 6 The mounting bracket 801 is detachably mounted on the frame 1;
[0109] The feeding cylinder 802 is mounted on the fixed frame 801. The feeding cylinder 802 is located on the side of the positioning component 3 near the axis of the turntable 2. The feeding cylinder 802 is connected and cooperated with the air supply equipment sold on the market, which can drive the output rod on the feeding cylinder 802 to move closer to or further away from the positioning component 3 in the radial direction of the turntable 2.
[0110] The feeding block 803 is connected to the output rod of the feeding cylinder 802. During the movement, the feeding block 803 can push the workpiece G on the positioning member 3 away from the positioning member 3.
[0111] A feeding ramp 804 is provided on the side of the positioning component 3 away from the feeding cylinder 802. The top of the feeding ramp 804 is lower than the surface of the workpiece G placed on the positioning component 3 in the vertical direction. After leaving the positioning component 3, the workpiece G will come to the feeding ramp 804 and move down along the feeding ramp 804 under the action of gravity. In actual production, the length of the feeding ramp 804 can be larger. The bottom of the feeding ramp 804 can be connected to the quality inspection table. Workers can perform quality inspection on the processed workpiece G on the quality inspection table. This enables continuous processing and quality inspection, further improving production efficiency.
[0112] Example 5
[0113] This embodiment discloses a method of using the aforementioned automated equipment, which includes the following steps:
[0114] Loading steps: Turntable 2 switches a positioning piece 3 without workpiece G to the loading station. Pushing power source 903 drives the drive gear 902 to rotate and drives the pusher seat 705 to slide away from the initial position away from the positioning piece 3, causing the stop bar 706 to swing from the blocking position to the conducting position. At this time, a workpiece G enters the swing table 702. Then, pushing power source 903 drives the drive gear 902 to rotate and drives the pusher seat 705 to slide away from the current position towards the positioning piece 3, causing the stop bar 706 to swing from the conducting position to the blocking position. After the pusher seat 705 pushes the workpiece G onto the positioning piece 3 at the loading station, pushing power source 903 drives the drive gear 902 to rotate and drives the pusher seat 705 to return from the current position to the initial position, completing one loading operation.
[0115] Drilling steps: Turntable 2 switches a positioning piece 3 carrying the workpiece G to the drilling station. Then, the clamping piece 6 at the drilling station cooperates with the corresponding positioning piece 3 to clamp the workpiece G. Then, the drilling mechanism 4 drills the workpiece G on the positioning piece 3 at the drilling station. After drilling is completed, the clamping piece 6 at the drilling station moves away from the corresponding positioning piece 3.
[0116] Tapping steps: Turntable 2 switches a positioning piece 3 carrying a completed drilling part to the tapping station. Then, the clamping piece 6 at the tapping station cooperates with the corresponding positioning piece 3 to clamp the workpiece G. Then, the tapping mechanism 5 performs tapping processing on the workpiece G on the positioning piece 3 at the tapping station. After the tapping is completed, the clamping piece 6 at the tapping station moves away from the corresponding positioning piece 3.
[0117] Unloading steps: Turntable 2 switches a positioning part 3 carrying tapped parts to the unloading station, and unloading mechanism 8 pushes the workpiece G on the positioning part 3 at the unloading station away from the positioning part 3;
[0118] The loading, drilling, tapping, and unloading steps can be performed simultaneously.
[0119] Through the technical solution of this embodiment, the four steps of loading, drilling, tapping and unloading are carried out simultaneously. The turntable 2 can complete one process and immediately enter the next stage after rotating one station. Compared with the traditional single-line serial processing, the equipment utilization rate is increased by several times. Assuming that the single process takes thirty seconds, it would take eight minutes to process four workpieces G in the traditional way, but only two minutes with the automated equipment operation of this embodiment, realizing full-process automation and achieving "zero-interval" production.
[0120] Furthermore, the automated equipment in this embodiment has flexible production compatibility, and each station can be started and stopped independently. For example, the tapping mechanism 5 can be temporarily shut down, skipping the tapping station and completing only the drilling process before unloading the material. This improves the applicability of the automated equipment in this embodiment.

Unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other. The present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
