Description

Technical Field

[0001] The present invention relates to the technical field of machining equipment, and in particular, to a vertical multi-station drilling and tapping machine. Background Art

[0002] In the field of modern machining, drilling and tapping, as key processes for workpiece machining, play a crucial role in the final quality and performance of workpieces. Most traditional drilling and tapping machining methods are realized by the way of manual assistance to machinery.

[0003] The way of manual assistance to machinery, although reducing the labor intensity of workers to a certain extent, still requires a large number of manual auxiliary operations due to its low degree of automation. Specifically, after the workpiece is drilled, due to the lack of the ability of multi-station linkage, the staff can only separately disassemble the drilled workpiece and then install it in the position area for tapping, and ensure the accurate position of the workpiece, so as to perform subsequent tapping processing. This process not only takes time, but also requires the staff to have certain operation skills and experience to avoid damaging the workpiece during disassembly and assembly; in addition, due to the lack of coordinated cooperation of multi-stations, the transfer of workpieces between different processes can only rely on manual disassembly and assembly, which not only takes time, but also easily causes the position of the workpiece to deviate due to manual operation errors. At the same time, the lack of multi-stations also means that continuous processing of workpieces cannot be realized. After each process is completed, manual loading and unloading and position adjustment of the workpiece are required, which greatly reduces the production efficiency and is difficult to meet the requirements of modern manufacturing for high-efficiency and high-quality production. Summary of the Invention

[0004] The present invention relates to a vertical multi-station drilling and tapping machine, which solves the problems that in the drilling and tapping processes of existing workpieces, due to the lack of multi-station linkage, after the workpiece is drilled, the staff needs to separately disassemble and accurately install it in the tapping position, which is time-consuming and requires operation skills to avoid damaging the workpiece, and the transfer between different processes depends on manual disassembly and assembly, which is easy to cause the position deviation of the workpiece due to manual errors, and continuous processing cannot be realized, reducing the production efficiency and being difficult to meet the requirements of modern manufacturing for high-efficiency and high-quality production.

[0005] The present invention provides a vertical multi-station drilling and tapping machine, which specifically includes: a mounting table, and a set of Z-axis screw feed assemblies are fixedly installed on both the left end face and the right end face of the mounting table; on the guide rail slider of the Z-axis screw feed assembly located on the left side, a tapping system assembly is fixedly installed through a connecting bracket; on the guide rail slider of the Z-axis screw feed assembly located on the right side, a drilling system assembly is fixedly installed through a connecting bracket;

[0006] A support platform is provided on the lower side of the installation platform. The top surface of the support platform and the bottom end surface of the installation platform are fixedly installed and connected through a circular connecting platform. An annular workbench is rotatably installed on the outer peripheral surface of the circular connecting platform through a bearing, and eight T-slot platforms are fixedly installed on the top surface of the annular workbench in an annular array.

[0007] Eight magnetic metal blocks are embedded in the bottom end surface of the annular workbench in an annular array. The eight magnetic metal blocks correspond to the positions of the eight T-slot platforms respectively. A monitoring column is fixedly installed on the left side of the top surface of the support platform. A group of intermittent in-place monitoring components are embedded in the top surface of the monitoring column. The intermittent in-place monitoring components are proximity switches, and the sensing end of the intermittent in-place monitoring components faces upward.

[0008] Further, the bottom end surface of the annular workbench is higher than the top surface of the monitoring column. When the magnetic metal block corresponds to the position of the monitoring column, the magnetic metal block is within the sensing range of the intermittent in-place monitoring component at this time.

[0009] Further, a bottom annular driving block is fixedly installed on the bottom end surface of the annular workbench. The outer diameter of the bottom annular driving block is the same as the outer diameter of the annular workbench, and the inner diameter of the bottom annular driving block is smaller than the inner diameter of the annular workbench. The bottom end surface of the bottom annular driving block is higher than the top surface of the support platform.

[0010] Further, a circle of gear teeth is installed on the inner peripheral surface of the bottom annular driving block in an annular array. The gear teeth are in the area away from the magnetic metal block.

[0011] Further, an internal installation cavity is provided in the front side of the support platform. A group of intermittent driving motors are fixedly installed on the inner end top surface of the internal installation cavity. The intermittent driving motors adopt electromagnetic brake motors. A driving gear is provided above the support platform. The rotating shaft end of the intermittent driving motor penetrates the top surface of the support platform and is fixedly installed and connected with the driving gear.

[0012] The driving gear meshes with the gear teeth.

[0013] Further, every time the driving gear rotates one circle, the annular workbench meshed with the driving gear through the gear teeth rotates one-eighth of a circle.

[0014] Further, a control housing is installed on the front end surface of the support platform. The control housing is externally connected to a power supply. A micro control unit is provided inside the control housing. The micro control unit is electrically connected to the Z-axis lead screw feeding component, the intermittent in-place monitoring component, the intermittent driving motor, the tapping system assembly and the drilling system assembly. A touch operation panel is embedded in the front end surface of the control housing. The touch operation panel is electrically connected to the micro control unit. An audible and visual alarm and a power button switch are fixedly installed on the right side of the front end surface of the control housing. The audible and visual alarm and the power button switch are both electrically connected to the micro control unit.

[0015] Furthermore, an intermittent arrival timing module is also arranged inside the control housing. The intermittent arrival timing module is electrically connected to the micro-control unit. The timing value of the intermittent arrival timing module is one second longer than the time for the rotating shaft end of the intermittent drive motor to rotate one circle.

[0016] When the intermittent arrival monitoring component does not sense the magnetic metal block, the intermittent arrival monitoring component feeds back a signal to the micro-control unit, and the micro-control unit controls the intermittent arrival timing module to start. Otherwise, it controls the intermittent arrival timing module to close. When the timing value of the intermittent arrival timing module is reached, the intermittent arrival timing module feeds back a signal to the micro-control unit, and the micro-control unit controls the sound and light alarm to start.

[0017] The present invention provides a vertical multi-station punching and tapping machine, which has the following beneficial effects:

[0018] 1. The annular workbench realizes circumferential rotation through the meshing of the driving gear and the teeth. Eight groups of T-slot platforms for workpiece installation are evenly arranged on the top of the annular workbench. Based on the meshing of the driving gear and the teeth, the positions are fed in an orderly manner, which is conducive to the punching and tapping operations of the workpieces to be processed installed on the annular workbench in sequence during the processing, realizing highly automated processing of multi-station automatic punching and tapping. Compared with the traditional processing method, the processing efficiency is greatly improved, the labor input is reduced, and the labor intensity is lowered.

[0019] 2. When the rotation of the annular workbench moves the workpiece at the target station below the punching system assembly, based on the induction feedback between the intermittent arrival monitoring component and the magnetic metal block, the Z-axis lead screw feeding component will be controlled to work, driving the punching system assembly to move downward along the Z-axis direction to perform precise punching operations on the workpiece. After the punching is completed, the Z-axis lead screw feeding component drives the punching system assembly to move upward along the Z-axis direction and return to the initial position, waiting for the next work instruction. Similarly, when the workpiece that has completed punching moves below the tapping system assembly, the above-mentioned induction, feedback, and control processes are repeated to perform tapping operations on the workpiece. Through this operation, the orderly progress of punching and tapping processing is ensured, and the stability and consistency of the processing quality are guaranteed.

[0020] 3. During the rotation of the annular workbench, the intermittent in-place monitoring component realizes the opening and closing of the intermittent in-place timing module according to whether it senses the magnetic metal block. Since the timing value of the intermittent in-place timing module is one second longer than the time for the shaft end of the intermittent drive motor to rotate one full circle, if the magnetic metal block is not sensed within the timing value of the intermittent in-place timing module, it indicates that the intermittent drive motor has failed, resulting in the annular workbench being unable to rotate one-eighth of a circle normally. At this time, based on the signal feedback of the intermittent in-place timing module, the audible and visual alarm is controlled to start, so as to prompt the abnormality of the equipment in the first time, facilitate the operator to stop the machine in time, avoid damage to the workpiece caused by equipment failure, reduce the scrap rate and production cost. On the contrary, if the equipment is fault-free, when the intermittent in-place monitoring component senses the magnetic metal block, based on its signal feedback, the intermittent in-place timing module in the timing state is controlled to close, avoiding false alarms and ensuring the stability and reliability of the equipment operation.

[0036] Refer to Figures 1 to 10 :

[0037] The present invention provides a vertical multi-station drilling and tapping machine, comprising: a mounting table 1. A set of Z-axis lead screw feed assemblies 101 are fixedly installed on both the left end face and the right end face of the mounting table 1. The basic structure of the Z-axis lead screw feed assembly 101 consists of parts such as a ball screw, a motor, a guide rail slider, etc., and is used to realize the vertical movement. As an existing mature technology, it will not be elaborated in detail here; on the guide rail slider of the Z-axis lead screw feed assembly 101 located on the left side, a tapping system assembly 2 is fixedly installed through a connecting bracket. The tapping system assembly 2 is usually composed of a power part, a transmission part, an execution part, a control system, etc., and is used to realize the tapping operation. Among them, the power part mostly uses a motor or a hydraulic pump to provide power for tapping; the transmission part is responsible for transmitting power and changing the form of motion, and common ones include gear transmission and worm and worm gear transmission; the execution part mainly includes a tap and is used to realize tapping; the control system generally uses a PLC, and parameters such as the tapping speed, feed rate, and torque are set through programming; the tapping system assembly 2, as a structure assembly that has been widely used and has a mature technology, its detailed structure and working principle will not be elaborated here; on the guide rail slider of the Z-axis lead screw feed assembly 101 located on the right side, a drilling system assembly 3 is fixedly installed through a connecting bracket. The drilling system assembly 3 is composed of a drilling execution component, a power supply component, a control system, etc., and is used to realize the drilling operation. Among them, the drilling execution component mainly includes a drill bit and is used to realize drilling; the power supply component provides the required power for the drilling execution component, and common power supply methods include electric and pneumatic; the control system generally uses a PLC, and parameters such as the drilling depth and speed are set through programming; the drilling system assembly 3, as a structure assembly that has been widely used and has a mature technology, its detailed structure and working principle will not be elaborated here;

[0038] A support table 102 is provided below the mounting table 1. The top end face of the support table 102 and the bottom end face of the mounting table 1 are fixedly installed and connected through a circular connecting table 109; the outer peripheral surface of the circular connecting table 109 is rotatably installed with an annular workbench 4 through a bearing 403, and eight T-slot platforms 402 are fixedly installed on the top end face of the annular workbench 4 in an annular array. Through the setting of the eight T-slot platforms 402, it can be used for the workpieces to be processed to realize multi-station installation;

[0039] Eight magnetic metal blocks 404 are embedded and installed in a circular array on the bottom end surface of the circular workbench 4. The eight magnetic metal blocks 404 correspond to the positions of eight T-slot platforms 402 respectively. On the left side of the top end surface of the support table 102, a monitoring column 108 is fixedly installed. A group of intermittent in-place monitoring components 1010 are embedded in the top end surface of the monitoring column 108. The intermittent in-place monitoring components 1010 are proximity switches. The sensing end of the intermittent in-place monitoring components 1010 faces the upper side. The bottom end surface of the circular workbench 4 is higher than the top end surface of the monitoring column 108. When the magnetic metal block 404 corresponds to the position of the monitoring column 108, at this time, the magnetic metal block 404 is within the sensing range of the intermittent in-place monitoring components 1010. Based on the above position description, when the T-slot platform 402 moves to the punching system assembly 3 position, the intermittent in-place monitoring components 1010 will sense the magnetic metal block 404 corresponding to the position of the T-slot platform 402, so as to realize the in-place feedback.

[0040] Among them, a bottom annular drive block 401 is fixedly installed on the bottom end surface of the circular workbench 4. The outer diameter of the bottom annular drive block 401 is the same as the outer diameter of the circular workbench 4, and the inner diameter of the bottom annular drive block 401 is smaller than the inner diameter of the circular workbench 4. The bottom end surface of the bottom annular drive block 401 is higher than the top end surface of the support table 102. Therefore, when the circular workbench 4 rotates, the bottom annular drive block 401 will not rub against the support table 102, so as to ensure the smoothness when the circular workbench 4 rotates.

[0041] Among them, a circle of teeth 405 are installed in a circular array on the inner circumferential surface of the bottom annular drive block 401. The teeth 405 are in the area far from the magnetic metal block 404. Therefore, it is ensured that the teeth 405 will not block the magnetic metal block 404, so as to ensure that the inductive cooperation between the magnetic metal block 404 and the intermittent in-place monitoring components 1010 is not affected. An internal installation cavity 1011 is provided in the front left side of the support table 102. A group of intermittent drive motors 1012 are fixedly installed on the inner end top surface of the internal installation cavity 1011. The intermittent drive motors 1012 are electromagnetic brake motors. Therefore, when the intermittent drive motors 1012 are not started, the electromagnetic brake takes effect and can effectively prevent the rotation of the rotating shaft, so as to avoid the rotation of the circular workbench 4 caused by factors such as vibration, and ensure that the position of the T-slot platform 402 is not affected. A drive gear 107 is provided above the support table 102. The rotating shaft end of the intermittent drive motor 1012 passes through the top end surface of the support table 102 and is fixedly installed and connected to the drive gear 107.

[0042] The drive gear 107 meshes with the teeth 405. Whenever the drive gear 107 rotates one circle, the circular workbench 4 meshed with the drive gear 107 through the teeth 405 rotates one-eighth of a circle. Therefore, the number of rotations is correspondingly matched with the number of T-slot platforms 402, and the automatic switching of work positions is realized in an orderly manner.

[0043] Among them, a control housing 103 is installed on the front end face of the support table 102. The control housing 103 is externally connected to a power supply. A micro control unit 1014 is provided inside the control housing 103. The micro control unit 1014 is electrically connected to the Z-axis lead screw feeding assembly 101, the intermittent in-place monitoring assembly 1010, the intermittent drive motor 1012, the tapping system assembly 2, and the drilling system assembly 3. A touch operation panel 106 is embedded and installed on the front end face of the control housing 103. The touch operation panel 106 is electrically connected to the micro control unit 1014. An audible and visual alarm 104 and a power button switch 105 are fixedly installed on the right side of the front end face of the control housing 103. Both the audible and visual alarm 104 and the power button switch 105 are electrically connected to the micro control unit 1014. An intermittent in-place timing module 1013 is further provided inside the control housing 103. The intermittent in-place timing module 1013 is electrically connected to the micro control unit 1014. The timing value of the intermittent in-place timing module 1013 is one second longer than the time for the rotating shaft end of the intermittent drive motor 1012 to rotate one circle. Therefore, as long as the intermittent drive motor 1012 operates normally, the intermittent in-place timing module 1013 will not give a false alarm.

[0044] When the intermittent in-place monitoring assembly 1010 does not sense the magnetic metal block 404, the intermittent in-place monitoring assembly 1010 feeds back a signal to the micro control unit 1014, and the micro control unit 1014 controls the intermittent in-place timing module 1013 to start. Otherwise, it controls the intermittent in-place timing module 1013 to close. When the timing value of the intermittent in-place timing module 1013 is reached, the intermittent in-place timing module 1013 feeds back a signal to the micro control unit 1014, and the micro control unit 1014 controls the audible and visual alarm 104 to start. Based on this feedback start, when the audible and visual alarm 104 starts, through its audible and visual warning, it can first-time warn the staff of the equipment abnormality, so that the staff can stop the machine in time for processing to avoid the occurrence of workpiece damage.

[0045] Working principle:

[0046] Press the power button switch 105 to connect the external power supply of the control housing 103, so that the equipment is in an operable state.

[0047] Install the workpiece to be processed on the T-slot platform 402 of the annular workbench 4. Then, send a workbench rotation instruction to the micro control unit 1014 through the touch operation panel 106. The micro control unit 1014 controls the intermittent drive motor 1012 to start. The rotating shaft end of the intermittent drive motor 1012 drives the drive gear 107 to rotate. Since the drive gear 107 meshes with the teeth 405 on the inner peripheral surface of the bottom annular drive block 401, the annular workbench 4 is driven to rotate. And every time the drive gear 107 rotates one circle, the annular workbench 4 rotates one-eighth of a circle, realizing automatic switching of workstations.

[0048] When the rotary table 4 rotates to move the workpiece at the target station below the drilling system assembly 3, the intermittent in-place monitoring component 1010 senses the corresponding magnetic metal block 404 and feeds back a signal to the micro control unit 1014. The micro control unit 1014 controls the Z-axis lead screw feeding component 101 to work, driving the drilling system assembly 3 to move downward along the Z-axis direction to drill the workpiece. After the drilling is completed, the Z-axis lead screw feeding component 101 drives the drilling system assembly 3 to move upward along the Z-axis direction and return to the initial position, waiting for the next work instruction;

[0049] Based on the continuous rotation of the rotary table 4, the workpiece that has completed drilling will eventually move below the tapping system assembly 2. Similarly, based on the sensing cooperation between the intermittent in-place monitoring component 1010 and the magnetic metal block 404, a signal is fed back to the micro control unit 1014. The micro control unit 1014 controls the Z-axis lead screw feeding component 101 to work, driving the tapping system assembly 2 to move downward along the Z-axis direction to tap the workpiece. After the tapping is completed, the Z-axis lead screw feeding component 101 drives the tapping system assembly 2 to move upward along the Z-axis direction and return to the initial position, waiting for the next work instruction;

[0050] When the workpiece has completed drilling and tapping operations, a stop instruction is sent to the micro control unit 1014 through the touch operation panel 106. The micro control unit 1014 controls the intermittent drive motor 1012, the Z-axis lead screw feeding component 101, the tapping system assembly 2, and the drilling system assembly 3 to stop working, and turns off the power button switch 105 to end the processing operation;

[0051] Based on the above operation process, the present invention can sequentially perform drilling and tapping operations on the workpieces at other stations on the rotary table 4, realizing automatic processing of multi-station automatic drilling and tapping, and improving the processing efficiency;

[0052] When the annular workbench 4 rotates, the magnetic metal block 404 that was originally inductively engaged with the intermittent in-place monitoring component 1010 moves out of its sensing range. When the intermittent in-place monitoring component 1010 does not sense the magnetic metal block 404, it feeds back a signal to the micro-control unit 1014. The micro-control unit 1014 controls the intermittent in-place timing module 1013 to start timing. If the intermittent in-place monitoring component 1010 still does not sense the magnetic metal block 404 (i.e., the next magnetic metal block 404 adjacent to the position of the previous magnetic metal block 404) within the timing value (one second longer than the time for the rotating shaft end of the intermittent drive motor 1012 to rotate one circle), it means that the intermittent drive motor 1012 has a fault, which may be due to power supply problems, control problems, or its own faults, etc., resulting in its inability to rotate the annular workbench 4 by one-eighth of a circle. Then the intermittent in-place timing module 1013 feeds back the signal to the micro-control unit 1014, and the micro-control unit 1014 controls the sound and light alarm 104 to start, indicating that the equipment is abnormal and needs to be shut down in time to avoid damaging the workpiece. On the contrary, if there is no fault, when the intermittent in-place monitoring component 1010 senses the magnetic metal block 404, it feeds back a signal to the micro-control unit 1014, and the micro-control unit 1014 controls the intermittent in-place timing module 1013 in the start-timing state to turn off to avoid false alarms.

When the timing value of the intermittent in-place timing module (1013) is reached, the intermittent in-place timing module (1013) feeds back a signal to the micro control unit (1014), and the micro control unit (1014) controls the audible and visual alarm (104) to start.
