Description

Technical Field

[0001] The invention belongs to the technical field of handle processing, and in particular relates to automated equipment for drilling and tapping handles. Background Art

[0002] In the lock industry, a handle (also known as a handle or pull) refers to the part of a lock used to manually operate the deadbolt. It is usually installed on the inside or outside of the door and is controlled by rotating, pressing down, or pulling to open and close the lock.

[0003] The handle production process requires die-casting, drilling, tapping and other processes. Currently, each process is carried out on a separate device. After completing one process, the handle needs to be transferred to another device. In this way, workers need to manually position and clamp the handle for each process, which is time-consuming and labor-intensive, and has 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 the present invention is to provide an automated equipment for handle drilling and tapping in response to the above-mentioned technical problems. This automated equipment integrates the drilling station, tapping station and operation station on a turntable-type automated equipment to achieve continuous automated processing of multiple processes. Compared with the traditional single-machine step-by-step processing method, it reduces the transfer time of the workpiece between different equipment and significantly improves production efficiency.

[0005] In view of this, the present invention provides an automated handle drilling and tapping device, comprising: A frame is provided with a turntable, on which at least three positioning members are arranged at intervals along the circumferential direction. The positioning members can perform preliminary positioning of the workpiece. The turntable can rotate relative to the frame and drive all the positioning members to switch sequentially between the operating station, drilling station and tapping station, and perform loading and unloading operations at the operating station; The drilling mechanism is arranged at the drilling station and can perform drilling processing on the workpiece on the positioning member located at the drilling station; The tapping mechanism is arranged at the tapping station and can perform tapping processing on the workpiece on the positioning piece located at the tapping station; Two groups of clamping parts are respectively arranged at the drilling station and the tapping station. The clamping parts can be close to the positioning parts to clamp the workpiece at the drilling station or the tapping station, and the clamping parts can be away from the positioning parts to release the workpiece.

[0006] The tool is then moved from the drilling station to the tapping station, where the worker moves the tool away from the tapping station and the drill moves the tool away from the tapping station.

[0007] In the above technical solution, further, the positioning member includes a fixed seat, a head positioning block and a tail positioning block. The fixed seat is installed on the turntable, and the head positioning block and the tail positioning block are both installed on the fixed seat. A space is formed between the head positioning block and the fixed seat for 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.

[0008] In the above technical solution, further, the clamping part includes a clamping plate and a clamping cylinder. The clamping cylinder can drive the clamping plate to approach or move 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, and the grooves are adapted to the outer contour of the head of the workpiece.

[0009] In the above technical solution, further, the operating station includes a loading station and an unloading station.

A loading mechanism is provided at the loading station. The loading mechanism can push one workpiece onto the positioning part at the loading station each time and complete the preliminary positioning. A unloading mechanism is provided at the unloading station. The unloading mechanism can push the workpiece on the positioning part at the unloading station away from the positioning part along the radial direction of the turntable.

[0010] In the above technical solution, further, the feeding mechanism includes: A storage ramp on which multiple workpieces can be stacked in sequence along the width of the workpieces, and the workpieces can leave the storage ramp from the bottom of the storage ramp; The piece display table is arranged below the bottom of the piece storage slope. A stop seat is provided on the side of the piece display table away from the piece storage slope. The stop seat can block the workpiece that is separated from the bottom of the piece storage slope. A matching seat is provided on the side of the stop seat close to the piece storage slope. The distance between the matching seat and the stop seat is adapted to the width of the workpiece. The pusher seat is arranged on the ornament table and slides along the radial direction of the turntable. The pusher seat passes through the space between the gear seat and the matching seat during the movement. The pusher seat can push the workpiece on the ornament table to the positioning piece at the loading station; The blocking rod is located above the push seat, and the connecting end of the blocking rod is rotatably connected to the blocking seat. When the free end of the blocking rod is in the conducting position, it can allow the workpiece to enter the swing table, and when the free end of the blocking rod is in the blocking position, it can prevent the workpiece from leaving the storage inclined surface; The push drive mechanism can drive the push seat to slide back and forth on the ornament table, and drive the blocking rod to swing between the conducting position and the blocking position.

[0011] In the above technical solution, further, the push drive mechanism includes: The rack is connected to the pusher seat, and the multiple teeth on the rack are distributed along the sliding direction of the pusher seat; A driving gear is rotatably arranged on the pendulum table, and the driving gear is meshed and connected with the rack; The pushing power source can drive the driving gear to rotate; The driving gear is coaxial with the rotating axis of the connecting end of the driving gear and the blocking rod. A push column is provided on the end surface of the driving gear close to the blocking rod. The push column can push the blocking rod from the blocking position to the conducting position in the process of following the movement of the driving gear. A reduction gear set, wherein the input end of the reduction gear set is connected to the driving gear, and the output end of the reduction gear set is connected to the driving gear; The elastic part is arranged on the ornament table and is connected to the blocking rod. When the blocking rod is located at the blocking position, the elastic part is in a relaxed state. When the blocking rod is located at the conducting position, the elastic part is squeezed and deformed.

[0012] In the above technical solution, further, when the pushing seat is in the initial position, the position between the two ends of the driving gear and the rack is connected, and at this time the push column does not contact the material blocking rod; in the process of the pushing seat sliding from the initial position toward the direction away from the positioning member, the push column pushes the material blocking rod from the blocking position to the conducting position; thereafter, in the process of the pushing seat sliding toward the direction close to the positioning member, the push column moves toward the direction away from the material blocking rod.

[0013] In the above technical solution, further, the blanking mechanism includes: A fixing frame, the fixing frame is arranged on the frame; The unloading cylinder is installed on the fixed frame. The unloading cylinder is located on the side of the positioning member close to the axis of the turntable. The output rod of the unloading cylinder can be close to or away from the positioning member in the radial direction of the turntable. The blanking block is connected to the output rod of the blanking cylinder. The blanking block can push the workpiece on the positioning piece away from the positioning piece during movement.

[0014] In the above technical solution, further, a blanking slope is provided on the side of the positioning member away from the blanking cylinder, and the top of the blanking slope is lower than the surface of the positioning member on which the workpiece is placed in the vertical direction.

[0015] The present invention also discloses a method for using the aforementioned automation equipment, which comprises the following steps: Loading steps: the turntable switches a positioning piece that does not carry a workpiece to the loading station, the pushing power source drives the active gear to rotate and drives the pushing seat to slide from the initial position toward the direction away from the positioning piece, so that the blocking rod swings from the blocking position to the conducting position. At this time, a workpiece enters the swing table, and then the pushing power source drives the active gear to rotate and drives the pushing seat to slide from the current position toward the positioning piece, so that the blocking rod swings from the conducting position to the blocking position. When the pushing seat pushes the workpiece onto the positioning piece at the loading station, the pushing power source drives the active gear to rotate and drives the pushing seat to return from the current position to the initial position, completing one loading operation; Drilling step: The turntable switches a positioning piece carrying the workpiece to be processed to the drilling station, and 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 the drilling is completed, the clamping piece at the drilling station moves away from the corresponding positioning piece. Tapping steps: The turntable switches a positioning piece with a completed drilling to the tapping station, and then the clamping piece at the tapping station cooperates with the corresponding positioning piece to clamp the workpiece. Then, the tapping mechanism taps the workpiece on the positioning piece at the tapping station. After the tapping is completed, the clamping piece at the tapping station moves away from the corresponding positioning piece. Unloading step: The turntable switches a positioning piece with tapping completed to the unloading station, and the unloading mechanism pushes the workpiece on the positioning piece at the unloading station away from the positioning piece; The loading step, drilling step, tapping step and unloading step can be performed simultaneously.

[0016] The beneficial effects of the present invention are: 1. By integrating drilling, tapping, and operating stations onto a turntable-type automated machine, continuous automated multi-process processing is achieved. Compared to traditional single-machine, step-by-step processing, this reduces workpiece transfer time between different devices, significantly improving production efficiency. Furthermore, by eliminating the need for manual repetitive positioning and clamping, workers' workload is reduced, human errors are avoided, and processing consistency is improved.

[0017] 2. By optimizing the operating stations into loading stations and unloading stations, a loading mechanism is set at the loading station to automatically load the workpiece, and a unloading mechanism is set at the unloading station to automatically unload the workpiece, which reduces the number of manual operations and further improves production efficiency.

[0018] 3. By designing the loading mechanism into a combination of a storage ramp, a display table, a shift seat, a matching seat, a push seat, a stop rod and a push drive mechanism, under the drive of the push drive mechanism, the push seat can push one workpiece onto the corresponding positioning piece at a time, and the stop rod can conduct or block the bottom of the storage ramp as needed, so that orderly loading can be achieved and loading failures caused by longitudinal stacking of multiple workpieces can be avoided.

[0019] 4. By designing the push drive mechanism into a combination of a rack, a driving gear, a push power source, a driving gear, a push column, a reduction gear set and an elastic part, when the pusher pushes the workpiece to the positioning part, the blocking rod moves synchronously to block the subsequent workpiece to avoid double material or material jamming. The movement of the pusher and the blocking rod form an error-proofing mechanism design, ensuring that new workpieces are allowed to enter only when the pusher retracts, and other workpieces in the storage slope are blocked during pushing, fundamentally eliminating the problem of multiple materials overlapping.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0037] The handle structure of the present invention is as follows Figure 1 As shown, the handle is L-shaped as a whole, including the grip portion G1 and the handle head G2. The drilling and tapping positions are both in the handle head G2. Figure 1 The handle to be processed is shown in the upper middle. In some cases, a shallow groove can be preliminarily machined at the drilling position of the workpiece G. Figure 1 The handle after drilling and tapping is shown in the lower middle portion. The automated equipment in the present invention mainly performs drilling and tapping on the handle head G2.

[0038] Example 1 This embodiment provides an automated device for drilling and tapping with a handle, comprising: a frame 1, a turntable 2, a plurality of positioning members 3, a drilling mechanism 4, a tapping mechanism 5, and two sets of clamping members 6; See also Figure 1 and Figure 2 , a turntable 2 is provided on the frame 1, and the turntable 2 can rotate relative to the frame 1, please refer to Figure 4 A switching power source 201 for driving the turntable 2 to rotate is provided at the bottom of the frame 1.

The control method of pausing after rotating the turntable 2 at a certain angle has been implemented in the art and will not be repeated here.

[0039] A plurality of positioning members 3 are provided on the turntable 2 at intervals along the circumferential direction. The positioning members 3 can perform preliminary positioning on the workpiece G. For example, see Figure 7The positioning member 3 includes a fixed seat 301, a head positioning block 302 and a tail positioning block 303. The fixed seat 301 is installed on the turntable 2. The fixed seat 301 and the turntable 2 can be detachably connected. The head positioning block 302 and the tail positioning block 303 are both installed on the fixed seat 301. A space is formed between the head positioning block 302 and the fixed seat 301 for the tail end of the workpiece G to pass through 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 stuck in the groove to realize the positioning of the head of the workpiece G; there are two groups of tail positioning blocks 303, and the two groups of tail positioning blocks 303 are spaced apart along the width direction of the workpiece G. A space adapted to the width of the workpiece G is formed between the two groups of tail positioning blocks 303. After passing through the space between the head positioning block 302 and the fixed seat 301, the tail end of the workpiece G can enter the space between the two groups of tail positioning blocks 303, so that the workpiece G is limited in the width direction, thereby realizing the positioning of the tail end of the workpiece G; Preferably, the head positioning block 302 is detachably connected to the fixing seat 301, and the positions of the two sets of tail positioning blocks 303 on the width of the workpiece G are adjustable, so that workpieces G of different widths can be adapted; The turntable 2 can drive all the positioning parts 3 to switch sequentially between the operation station, the drilling station and the tapping station. For example, the positioning parts 3 can be switched from the operation station to the drilling station, then from the drilling station to the tapping station, and finally from the tapping station back to the operation station. At the operation station, workers can perform loading and unloading operations. The drilling mechanism 4 is arranged at the drilling station, and the drilling mechanism 4 can perform drilling processing on the workpiece G on the positioning member 3 located at the drilling station; The tapping mechanism 5 is provided at the tapping station, and the tapping mechanism 5 can perform tapping processing on the workpiece G on the positioning member 3 located at the tapping station; In this embodiment, the drilling mechanism 4 and the tapping mechanism 5 both include a stand, a lifting structure, a mounting seat, a processing power source and a tool, wherein the stand is mounted on the frame 1, the lifting structure is mounted on the stand, the lifting structure can drive the mounting seat to move in the vertical direction, the processing power source and the tool are both mounted on the mounting seat, the processing power source can select a combination of a motor and a reducer, the processing power source can drive the tool to rotate to process the workpiece G, in the drilling mechanism 4, the tool is a drill bit, and in the tapping mechanism 5, the tool is a tap; illustratively, the lifting structure can select a combination of a screw rod, a nut and a motor, the screw rod is mounted on the stand, the motor is used to drive the screw rod to rotate, the nut is set on the mounting seat, the mounting seat is vertically slidably connected to the stand, and the mounting seat is connected to the screw rod through the nut, thereby realizing the lifting of the mounting seat; Two sets of clamping members 6 are respectively arranged 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. For example, see Figure 7 The clamping member 6 includes a clamping plate 601 and a clamping cylinder 602. The clamping cylinder 602 is installed on a stand corresponding to the workstation. The clamping cylinder 602 is connected to the air supply equipment sold on the market and can drive the clamping plate 601 to approach or move away from the head positioning block 302 along the radial direction of the turntable 2. A groove is also provided on the side wall of the clamping plate 601 close to the head positioning block 302. The groove cooperates with the groove on the head positioning block 302, so that the clamping plate 601 can finally position the workpiece G through the two grooves when it is close to the head positioning block 302, and clamp the workpiece G through the clamping plate 601 and the head positioning block 302. When the clamping plate 601 is away from the workpiece G, it will not interfere with the turntable 2 in switching the workstation of the positioning member 3 carrying the workpiece G. In this embodiment, the worker places the workpiece G to be processed on the positioning member 3 at the operating station, and the turntable 2 switches the positioning member 3 carrying the workpiece G to be processed 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 where the hole to be drilled on the workpiece G is opposite to the position of the drilling mechanism 4, and the drilling mechanism 4 performs drilling on the workpiece G. After the drilling is completed, the clamping member 6 moves away from the positioning member 3 to release the workpiece G, and then the turntable 2 moves the positioning member 3 carrying the drilled workpiece G from the operating station to the drilling station. The drilling station switches to the tapping station. At the tapping 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 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 member 6 moves away from the positioning member 3 to release the workpiece G. Then, the turntable 2 switches the positioning member 3 carrying the workpiece G after drilling and tapping from the tapping station to the operating station. At the operating station, the worker removes the completed workpiece G, completing the processing of one workpiece G. In this embodiment, at least three positioning members 3 are provided, and when one positioning member 3 is located at the operating station, one positioning member 3 is located at the drilling station, and one positioning member 3 is located at the tapping station. In this way, after a period of time since the start of production, when the worker is loading or unloading materials at the operating station, the drilling station is simultaneously performing drilling processing, and the tapping station is simultaneously performing tapping processing, thereby realizing continuous production processing and improving production efficiency.

[0040] In this embodiment, the station switching of the turntable 2 to the positioning member 3 and the operation control of the drilling mechanism 4 and the tapping mechanism 5 are all controlled by the control box to achieve automated processing. The control box is set on the frame 1.

[0041] In addition, during the drilling and tapping processes, cutting fluid can be sprayed onto the processing parts to achieve better cooling and lubrication effects.

A loading mechanism 7 is provided at the loading station. The loading mechanism 7 can push one workpiece G onto the positioning part 3 at the loading station each time and complete the preliminary positioning. A unloading mechanism 8 is provided at the unloading station. The unloading mechanism 8 can push the workpiece G on the positioning part 3 at the unloading station away from the positioning part 3 along the radial direction of the turntable 2; See also Figure 1 and Figure 2 In this embodiment, at least four positioning members 3 are provided. When there is one positioning member 3 at the loading station, there is one positioning member 3 at the drilling station, the tapping station, and the unloading station, so that continuous production can be achieved. See also Figure 5 and Figure 6 At the beginning 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 along the radial direction of 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 will switch the positioning piece 3 carrying the workpiece G to the drilling station for drilling processing, and then the turntable 2 will switch the positioning piece 3 carrying the drilled workpiece G to the tapping station for tapping processing. Finally, the turntable 2 will switch the positioning piece 3 carrying the drilled and tapped workpiece G to the unloading station, and the unloading mechanism 8 will push the workpiece G away from the positioning piece 3 at the unloading station. After a period of production, the four stations can operate simultaneously to realize continuous production and processing.

The workpieces G can leave the storage slope 701 from the bottom of the storage slope 701. In order to prevent multiple workpieces G from being stacked longitudinally on the storage slope 701, a baffle is provided on the storage slope 701 to limit the movable height of the workpieces G. Figure 5 and Figure 67 shows a schematic diagram of multiple workpieces G being stored on the storage ramp 701. In actual production, the length of the storage ramp 701 can be longer, and the workpieces G on the storage ramp 701 can be transferred to the storage ramp 701 after the previous process is completed. The display stand 702 is mounted on the rack 1 and is located below the bottom of the storage ramp 701. Figure 8 and Figure 9 , a stopper seat 703 is provided on the side of the ornament table 702 away from the piece storage inclined surface 701, and the stopper seat 703 can block the workpiece G from escaping from the bottom of the piece storage inclined surface 701, and a matching seat 704 is provided on the side of the stopper seat 703 close to the piece storage inclined surface 701. The distance between the matching seat 704 and the stopper 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 stopper seat 703 and the matching seat 704, an inclined surface can be machined on the top of the side wall of the stopper seat 703 close to the matching seat 704, and at the same time, an inclined surface can be machined on the top of the side wall of the matching seat 704 close to the stopper seat 703; See also Figure 8 and Figure 10 A slide groove is provided on the ornament table 702, and a 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 ornament table 702. During the movement, the pusher seat 705 passes through the space between the gear seat 703 and the matching seat 704. The pusher seat 705 can push the workpiece G on the ornament table 702 to the positioning member 3 at the loading station; See also Figure 8 and Figure 9 When the free end of the blocking rod 706 is swung to the bottom of the storage slope 701 near the bottom of the blocking rod 706, the blocking rod 706 is in the conduction position, and the workpiece G is allowed to enter the ornament table 702. When the free end of the blocking rod 706 is swung to the bottom of the storage slope 701 near the bottom of the storage slope 701, the blocking rod 706 is in the conduction position, and the blocking rod 706 is in the conduction position, and the workpiece G is allowed to enter the ornament table 702. Figure 10 As shown, the blocking rod 706 is in the blocking position, which can block the workpiece G from leaving the storage ramp 701; The push drive mechanism 9 can drive the push seat 705 to slide back and forth on the ornament table 702, and drive the blocking rod 706 to swing between the conducting position and the blocking position; In this embodiment, the pusher drive mechanism 9 includes: a rack 901, a driving gear 902, a pusher power source 903, a driving gear 904, a reduction gear set 10, and an elastic member 11; See also Figure 9The ornament table 702 is in an inverted U shape, and the rack 901 is located below the ornament table 702. The 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 is connected to the rack 901. When the rack 901 moves, it will move with the pusher seat 705. See also Figure 9 , the driving gear 902 is rotatably arranged on the pendulum table 702, and the driving gear 902 is meshed with the rack 901; the pushing power source 903 can drive the driving gear 902 to rotate, and the pushing power source 903 can be selected from the combination of a servo motor and a reducer, and the pushing power source 903 can be installed on the frame 1, such as Figure 9 As shown in FIG, the pushing power source 903 can also be installed in the gear seat 703. In this case, the gear seat 703 is designed to have a mounting groove inside. See also Figure 8 and Figure 9 , the rotation axis of the connecting end of the driving gear 904 and the blocking rod 706 is coaxially distributed, and a push column 905 is provided on the end surface of the driving gear 904 close to the blocking rod 706. The push column 905 can push the blocking rod 706 from the blocking position to the conducting position in the process of following the movement of the driving gear 904; See also 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 use a reduction structure formed by multiple gears in the prior art, and the reduction gear set 10 can reduce the speed of the driving gear 902 and transmit it to the driving gear 904, which means that the driving gear 902 rotates multiple circles, and the driving gear 904 only rotates half a circle or one circle; and, 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 rotation direction. At this time, it can be achieved by simply meshing an external gear between the output gear of the reduction gear set 10 and the driving gear 904; See also Figure 10 , the elastic member 11 is arranged on the ornament table 702 or the gear seat 703, and the elastic member 11 is connected to the blocking rod 706. When the blocking rod 706 is in the blocking position, the elastic member 11 is in a relaxed state. The elastic member 11 can be a torsion spring, a compression spring, etc. in the prior art. The elastic member 11 has a certain stiffness, so that the elastic member 11 can block the multiple workpieces G on the storage inclined surface 701 in the natural state. When the blocking rod 706 is in the conducting position, the elastic member 11 is squeezed and deformed; In this embodiment, when the pushing seat 705 is in the initial position, the driving gear 902 is connected to the position between the two ends of the rack 901, which means that the rack 901 can move in two directions at this time, and the push post 905 is not in contact with the material blocking rod 706, or the push post 905 just contacts the material blocking rod 706, and no external force is applied to the material blocking rod 706; in the process of the pushing seat 705 sliding from the initial position to the direction away from the positioning member 3, the push post 905 pushes the material blocking rod 706 from the blocking position to the conducting position; thereafter, in the process of the pushing seat 705 sliding in the direction close to the positioning member 3, the push post 905 moves in the direction away from the material blocking rod 706; In this embodiment, the loading of the workpiece G by the loading mechanism 7 can be divided into three stages: The first stage of loading is shown in Figure 11 , Figure 11 The left side of the middle shows the schematic diagram when the push seat 705 is in the initial position. At this time, the blocking rod 706 is in the blocking position. When the active gear 902 rotates clockwise to drive the rack 901 to move away from the positioning member 3, the active gear 902 drives the driving gear 904 to rotate counterclockwise through the reduction gear set 10. In this process, the push column 905 pushes the free end of the blocking rod 706 to swing counterclockwise, causing the blocking rod 706 to swing from the blocking position to the conducting position. At the same time, the elastic member 11 is squeezed and deformed, and the Figure 11 In the diagram on the middle right, the workpiece G on the storage slope 701 passes through the bottom of the storage slope 701 and reaches the display table 702. At this time, the head of the workpiece G on the display table 702 can block other workpieces G on the storage slope 701. The second stage of loading is shown in Figure 12 , after a workpiece G comes onto the ornament table 702, as Figure 12 As shown on the left side of the middle diagram, the active gear 902 rotates counterclockwise to drive the rack 901 to move toward the positioning member 3, and the active gear 902 drives the driving gear 904 to rotate clockwise through the reduction gear set 10. During this process, the push post 905 gradually moves away from the blocking rod 706, and the blocking rod 706 is always in contact with the push post 905 under the push of the elastic member 11 until the blocking rod 706 reaches the blocking position, and the blocking rod 706 is obtained. Figure 12 As shown in the diagram on the middle right side, at this time, the free end of the blocking rod 706 blocks the workpiece G on the storage inclined surface 701, and in the process where the rack 901 continues to move toward the positioning member 3 to push the workpiece G onto the positioning member 3, the push pin 905 has been separated from the blocking rod 706 and will not affect the blocking rod 706. When the workpiece G has been pushed onto the positioning member 3, the push pin 905 will not contact the other side wall of the blocking rod 706. The third stage of loading is shown in Figure 13 After the pusher 705 pushes the workpiece G onto the positioning member 3, as shown in FIG. Figure 13As shown on the left side of the middle diagram, the driving gear 902 rotates clockwise to drive the rack 901 to move away from the positioning member 3, and the driving gear 902 drives the driving gear 904 to rotate counterclockwise through the reduction gear set 10. During this process, the push post 905 gradually approaches the blocking rod 706. When the pushing seat 705 returns to the initial position, the driving gear 902 stops rotating. At this time, the push post 905 is not in contact with the blocking rod 706 or just in contact with the blocking rod 706, and will not push the blocking rod 706; Each time the feeding mechanism 7 feeds materials, the operation from the first stage to the third stage is completed.

[0044] In this embodiment, the pusher seat 705 is driven to move linearly by the cooperation of the gear and the rack 901, and the transmission accuracy is high; the rotational force of the driving gear 902 is transmitted to the driving gear 904 through the reduction gear set 10, and then the position switching of the blocking rod 706 is controlled by the push column 905 on the driving gear 904 and the elastic member 11. In this way, the operation sequence of the feeding, pushing and blocking of the feeding mechanism 7 is improved through pure mechanical transmission, the failure rate is low, and it is suitable for high-frequency continuous operation; In addition, the elastic member 11 is in a natural state when the material blocking rod 706 is in the blocking position and is only compressed when it is in the conducting position, which reduces the long-term force loss of the elastic member 11 and extends the service life of the elastic member 11; and since the elastic member 11 is in a natural state when the material blocking rod 706 is in the blocking position, when it is necessary to disassemble and repair the pusher seat 705, or to disassemble and repair the reduction gear group 10, there can be a workpiece G on the storage slope 701, that is, it is allowed to temporarily pause the equipment during the processing to perform the above-mentioned disassembly and repair operations, without having to first remove the workpiece G on the storage slope 701, so that after the disassembly and repair operations are completed, production can be started immediately, saving the time for unloading and loading on the storage slope 701, and further improving production efficiency.

[0045] Example 4 This embodiment further discloses a structure of the blanking mechanism 8 based on the embodiment 2; In this embodiment, the blanking mechanism 8 includes: a fixed frame 801, a blanking cylinder 802, a blanking block 803 and a blanking slope 804; See also Figure 3 or Figure 6 , the fixing frame 801 is detachably mounted on the frame 1; The unloading cylinder 802 is mounted on the fixed frame 801 and is located on the side of the positioning member 3 close to the axis of the turntable 2. The unloading cylinder 802 is connected to a commercially available air supply device to drive the output rod on the unloading cylinder 802 to move closer to or away from the positioning member 3 in the radial direction of the turntable 2. The blanking block 803 is connected to the output rod of the blanking cylinder 802. The blanking block 803 can push the workpiece G on the positioning member 3 away from the positioning member 3 during movement. A discharge slope 804 is provided on the side of the positioning member 3 away from the discharge cylinder 802. The top of the discharge slope 804 is lower than the surface of the workpiece G placed on the positioning member 3 in the vertical direction. After leaving the positioning member 3, the workpiece G will come to the discharge slope 804 and move downward along the discharge slope 804 under the action of gravity. In actual production, the length of the discharge slope 804 can be larger, and the bottom of the discharge slope 804 can be connected to the quality inspection table. Workers perform quality inspection on the processed workpiece G on the quality inspection table, which can achieve continuous processing and quality inspection, further improving production efficiency.

[0046] Example 5 This embodiment discloses a method for using the aforementioned automation equipment, which includes the following steps: Loading steps: the turntable 2 switches a positioning member 3 that does not carry the workpiece G to the loading station, the pushing power source 903 drives the active gear 902 to rotate and drives the pushing seat 705 to slide from the initial position toward the direction away from the positioning member 3, so that the blocking rod 706 swings from the blocking position to the conducting position. At this time, a workpiece G enters the ornament table 702, and then the pushing power source 903 drives the active gear 902 to rotate and drives the pushing seat 705 to slide from the current position toward the positioning member 3, so that the blocking rod 706 swings from the conducting position to the blocking position. When the pushing seat 705 pushes the workpiece G onto the positioning member 3 at the loading station, the pushing power source 903 drives the active gear 902 to rotate and drives the pushing seat 705 to return from the current position to the initial position, completing a loading operation; Drilling step: The turntable 2 switches a positioning member 3 carrying a workpiece G to be processed to the drilling station. Then, the clamping member 6 at the drilling station cooperates with the corresponding positioning member 3 to clamp the workpiece G. Then, the drilling mechanism 4 drills the workpiece G on the positioning member 3 at the drilling station. After drilling is completed, the clamping member 6 at the drilling station moves away from the corresponding positioning member 3. Tapping step: The turntable 2 switches a positioning piece 3 with a completed drilling 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 taps 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. Blanking step: the turntable 2 switches a positioning piece 3 with tapping completed to the blanking station, and the blanking mechanism 8 pushes the workpiece G on the positioning piece 3 at the blanking station away from the positioning piece 3; The loading, drilling, tapping and blanking steps can be performed simultaneously; Through the technical solution of this embodiment, the four steps of loading, drilling, tapping, and unloading are carried out simultaneously. Each time the turntable 2 rotates one station, one process is completed and the next step is immediately entered. Compared with traditional single-line serial processing, the equipment utilization rate is more than increased by several times. Assuming that a single process takes 30 seconds, the traditional method of processing four workpieces G takes eight minutes, while the automated equipment of this embodiment only takes two minutes, realizing full process automation and achieving "zero-interval" production. In addition, the automation equipment of this embodiment has flexible production compatibility, and each workstation can be started and stopped independently. For example, the tapping mechanism 5 can be temporarily closed, and the tapping station can be skipped to complete only the drilling process before unloading. This improves the scope of application of the automation equipment of this embodiment.
