Description

Technical Field

[0002] In the field of mechanical processing, drilling and tapping are common processing operations. Traditionally, drilling and tapping are usually performed separately on different equipment. For example, the drilling operation is completed on a drilling machine, and then the workpiece is transferred to a tapping machine for tapping.

[0003] However, in the prior art, during the operation of the drilling and tapping machine, since the workpiece needs to be processed on multiple devices, each clamping and processing operation will introduce new positioning errors. Even if a high processing accuracy can be guaranteed on each device, the accumulated positioning errors may cause the hole position and thread accuracy of the final product to not meet the requirements. In addition, the temperature changes during operation will cause the material to expand or generate thermal stress, resulting in changes in the size of the workpiece, causing the dimensional accuracy of the processed holes and threads to exceed the tolerance, affecting the matching accuracy with other components. Therefore, it is necessary to propose an automated drilling and tapping machine. Summary of the invention

Even if a high processing accuracy can be guaranteed on each device, the accumulated positioning errors may cause the hole position and thread accuracy of the final product to not meet the requirements, and the temperature changes generated during the operation will cause the material to expand due to heat or generate thermal stress, resulting in changes in the size of the workpiece, causing the dimensional accuracy of the processed holes and threads to exceed the tolerance, affecting the matching accuracy with other parts.

According to the data, the phase change process and heat dissipation rate of the phase change material column are controlled to ensure that it works within the appropriate temperature range. If the temperature of the phase change material column continues to rise after absorbing heat to a certain extent, the control system will further adjust the processing parameters of the equipment, such as reducing the spindle speed and feed speed of drilling or tapping, so as to reduce the heat generation during the processing. In addition, when the contact end of the heat-conducting fin is in contact with the workpiece, part of the heat will be transferred to the surrounding air to assist in heat dissipation, so as to maintain the workpiece temperature within a reasonable range and ensure the processing accuracy. During the processing, the position and angle of the temperature-controlled phase change adjustment structure can be dynamically adjusted according to the temperature changes of different parts of the workpiece, which effectively avoids the problem of reduced processing accuracy caused by excessive local temperature, improves the quality stability and consistency of the product, reduces the temperature fluctuation range of the workpiece by 50% to 70%, reduces the thermal stress and deformation of the material caused by temperature fluctuations, extends the service life of the tool, and improves the processing efficiency by about 20% to 30%.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, the logic controller detects the center position of the workpiece in real time according to the data transmitted by the laser calibration sensor and the center detection sensor in cooperation with the adaptive position correction component, so as to ensure that the workpiece is always kept on the central axis of the equipment during the processing, avoid the processing accuracy problem caused by eccentricity, calculate the deviation value between the workpiece and the ideal processing position, and then feed it back to the first belt drive structure and the second belt drive structure and the pulley motor structure, so as to control the first belt drive structure and the second belt drive structure to work, drive the pressure contact piece to move through the belt transmission, and the pressure sensor in the pressure contact piece monitors the contact in real time. Contact pressure, when the contact end contacts the workpiece and reaches the preset pressure, the pressure sensor feeds back the signal to the logic controller. At this time, the memory metal block deforms slightly due to the pressure, and its deformation is also recorded by the pressure sensor and transmitted to the logic controller, which further assists in determining the precise position of the workpiece. By using the dynamically formed contact adjustment, the pressure contact piece can form contact with the other side of the processing position of the workpiece during processing, reducing the introduction of new positioning errors during each clamping and processing operation, reducing the accumulated positioning errors, and the impact on the hole position and thread accuracy of the product, achieving accurate calibration of the workpiece position, and controlling the position deviation within a very small range.

[0018] 2. In the present invention, with the cooperation of the thermal change auxiliary control component, the rotating motor structure drives the driving motor structure to rotate and adjust at the bottom notch end of the magnetic positioning sliding seat, so that the driving motor structure is adjusted to a suitable angle direction, so as to perform precise positioning operations on the temperature control phase change adjustment structure later. Then the driving motor structure is started, and the rotating teeth at the top output end drive the fan gear to rotate, thereby rotating the synchronous shaft, driving the temperature control phase change adjustment structure to rotate as a whole to a position in close contact with the workpiece processing part. At this time, the contact end of the heat conductive fin is in contact with the surface of the workpiece. When the temperature of the workpiece processing position continues to rise, the phase change material column begins to undergo phase change, absorbing a large amount of heat, thereby slowing down the temperature rise rate of the workpiece. At the same time, the temperature control adjustment unit controls the phase change process and heat dissipation rate of the phase change material column according to the feedback data of the temperature sensor to ensure that it works within a suitable temperature range. If After the phase change material column absorbs heat to a certain extent, the temperature still has a tendency to continue to rise. The control system will further adjust the processing parameters of the equipment, such as reducing the spindle speed and feed speed of drilling or tapping, so as to reduce the heat generated during the processing. In addition, the contact end of the heat-conducting fin will also transfer part of the heat to the surrounding air during the contact with the workpiece to assist in heat dissipation, so as to maintain the workpiece temperature within a reasonable range and ensure the processing accuracy.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1: In the present invention, referring to Figure 1 - Figure 7 As shown: an automated drilling and tapping integrated machine, comprising a bearing drive seat 1, an automatic claw clamp adjustment fixing seat 5 is installed on the top side end of the bearing drive seat 1, an adaptive position correction component 7 is installed on the top end of the bearing drive seat 1, a drilling and tapping structure 2 is installed on the other side end of the top of the bearing drive seat 1, a thermal change auxiliary regulation component 8 is installed on the side end of the adaptive position correction component 7, and the top end of the bearing drive seat 1 is fastened with a toothed alveolar vertical column 6;

[0029] The adaptive position correction component 7 includes a support plate frame 71, and a pulley motor structure 72 is set inside the support plate frame 71. The output end of the pulley motor structure 72 is connected to a driving gear 73, and the center end of the driving gear 73 is connected to a stabilizing slot frame 74. The side end of the driving gear 73 is meshed with a position outer ring gear 75, and the position outer ring gear 75 is located inside the tooth groove vertical column 6 to form a meshing connection. The inside of the position outer ring gear 75 is fastened and connected with a connecting frame 78. The top side end of the connecting frame 78 is mounted with a first belt drive structure 76, and a calibration slot frame 77 is installed on the side end of the first belt drive structure 76. The side end of the calibration slot frame 77 is installed with a second belt drive structure 79. The output ends of the first belt drive structure 76 and the second belt drive structure 79 are connected to a pressure contact 790 through the signal control of an external logic controller. The pressure contact 790 consists of a pressure sensor, a memory metal block and a contact end. A laser calibration sensor 791 and a center detection sensor 792 are respectively installed on the bottom end surface of the calibration slot frame 77.

[0030] In a specific scheme, the workpiece to be processed is first placed on the automatic claw clamp adjustment fixing seat 5 on the top of the bearing drive seat 1. The automatic claw clamp adjustment fixing seat 5 automatically adjusts the clamping force and position according to the shape and size of the workpiece to ensure that the workpiece is firmly fixed in a suitable processing position. At the same time, the adaptive position correction component 7 starts to work, so that the pulley motor structure 72 starts to drive the driving gear 73 to rotate, and the driving gear 73 engages with the position outer ring gear 75, so that the position outer ring gear 75 rotates in the tooth groove vertical column 6, thereby driving the connecting frame 78 and the first belt drive structure 76 and the calibration slot frame 77 thereon to adjust the overall position, so that the calibration slot frame 77 is close to the workpiece, and the laser at the bottom of the calibration slot frame 77 is used. The calibration sensor 791 emits a laser beam to scan and detect the initial position of the workpiece, obtain the approximate outline and position information of the workpiece, and transmit these data to the external logic controller. After the workpiece position is accurately calibrated, the drilling and tapping structure 2 starts the processing operation. According to the processing requirements, the drilling and tapping structure 2 selects a suitable drill bit or tap, and adjusts the spindle speed, feed speed and other parameters, and then performs the drilling operation. The drill bit rotates at a high speed driven by the spindle, and gradually penetrates into the workpiece along the predetermined drilling path, and drills the required hole in the workpiece. During the drilling process, the thermal change auxiliary control component 8 monitors the temperature change of the processing area in real time. Secondly, the logic controller calculates the workpiece according to the data transmitted by the laser calibration sensor 791. The deviation value between the workpiece and the ideal processing position is then controlled by the first belt drive structure 76 and the second belt drive structure 79 to work, and the pressure contact member 790 is driven to move by the belt transmission. The pressure sensor in the pressure contact member 790 monitors the contact pressure in real time. When the contact end contacts the workpiece and reaches the preset pressure, the pressure sensor feeds back the signal to the logic controller. At this time, the memory metal block undergoes a slight deformation due to the pressure, and its deformation is also recorded by the pressure sensor and transmitted to the logic controller, which further assists in determining the precise position of the workpiece. The contact adjustment formed dynamically is used to enable the pressure contact member 790 to form contact with the other side of the processing position of the workpiece during processing, thereby reducing the introduction of new components during each clamping and processing operation. The positioning error is reduced, and the accumulated positioning error is reduced, which affects the hole position and thread accuracy of the product. The center detection sensor 792 is used to detect the center position of the workpiece in real time to ensure that the workpiece is always kept on the central axis of the equipment during the processing, avoiding the processing accuracy problem caused by eccentricity, and feedback is given to the first belt drive structure 76 and the second belt drive structure 79, and the pulley motor structure 72. Then, through the coordinated work of the laser calibration sensor 791, the pressure contact part 790 and the center detection sensor 792, the workpiece position is accurately calibrated, and the position deviation is controlled within a very small range. After the drilling is completed, the drilling and tapping structure 2 automatically replaces the tap, performs tapping operations, and processes threads in the drilled hole.

[0031] Embodiment 2: In the present invention, according to Figure 1 - Figure 3 , Figure 6 and Figure 7 As shown, the thermal change auxiliary regulation component 8 includes a bearing column 81, which is fastened on the top wall surface of the support plate frame 71. A semi-circular electromagnetic guide rail 82 is installed on the top of the bearing column 81, and a magnetic positioning sliding seat 83 is slidably connected inside the bottom end of the semi-circular electromagnetic guide rail 82.

[0032] A rotating motor structure is installed at the bottom notch end of the magnetic positioning sliding seat 83 , and a driving motor structure 84 is installed at the side end of the rotating motor structure.

[0033] The rotating motor structure drives the driving motor structure 84 located at the bottom notch end of the magnetic positioning sliding seat 83 to form a rotation adjustment. The top output end of the driving motor structure 84 is connected to a rotating tooth 88, and the side end of the rotating tooth 88 is meshed with a fan gear 89.

[0034] The bottom of the fan gear 89 is rotatably connected to a synchronous rotating shaft 85 , and the outer peripheral side of the synchronous rotating shaft 85 is rotatably connected to a temperature-controlled phase change regulating structure 86 .

[0035] The temperature control phase change regulating structure 86 is composed of a temperature sensor, a phase change material column and a temperature control regulating unit. A heat conducting fin contact end 87 is installed at the front end of the temperature control phase change regulating structure 86 .

[0036] In a specific scheme, when the automatic drilling and tapping machine starts processing, the temperature sensor in the temperature control phase change adjustment structure 86 begins to monitor the temperature changes in the workpiece processing area in real time. As the processing proceeds, if the temperature sensor detects that the temperature rises and exceeds the preset normal processing temperature threshold, the temperature signal is transmitted to the control system of the integrated machine, so that the control system starts the rotating motor structure according to the received signal, and the rotating motor structure drives the drive motor structure 84 to rotate and adjust at the bottom notch end of the magnetic positioning sliding seat 83, so that the drive motor structure 84 is adjusted to a suitable angle direction, so as to perform precise positioning operation on the temperature control phase change adjustment structure 86 later. Then the drive motor structure 84 is started, and the rotating gear 88 at the top output end drives the fan gear 89 to rotate, thereby rotating the synchronous shaft 85, driving the temperature control phase change adjustment structure 86 to rotate as a whole to a position in close contact with the workpiece processing part. At this time, the contact end 87 of the heat conductive fin is in contact with the surface of the workpiece. When the temperature of the workpiece processing position continues to rise, the phase change material column begins to undergo phase change, absorbing a large amount of heat, thereby slowing down the work. At the same time, the temperature control unit controls the phase change process and heat dissipation rate of the phase change material column according to the feedback data of the temperature sensor to ensure that it works within the appropriate temperature range. If the temperature of the phase change material column continues to rise after absorbing a certain degree of heat, the control system will further adjust the processing parameters of the equipment, such as reducing the spindle speed and feed speed of drilling or tapping, so as to reduce the heat generation during the processing. In addition, the contact end 87 of the heat conducting fin will also transfer part of the heat to the surrounding air during the contact process with the workpiece to assist in heat dissipation, so as to maintain the temperature of the workpiece within a reasonable range and ensure the processing accuracy. During the processing, the position and angle of the temperature control phase change adjustment structure 86 can be dynamically adjusted according to the temperature changes of different parts of the workpiece, which effectively avoids the problem of reduced processing accuracy caused by excessive local temperature, improves the quality stability and consistency of the product, reduces the temperature fluctuation range of the workpiece by 50% to 70%, reduces the thermal stress and deformation of the material caused by temperature fluctuations, extends the service life of the tool, and improves the processing efficiency by about 20% to 30%.

[0037] Embodiment 3: In the present invention, according to Figure 1 - Figure 3 As shown, a drilling and tapping installation fixture 4 is installed at the front end of the drilling and tapping structure 2, and a bottom sliding seat is fastened to the bottom of the drilling and tapping structure 2, and the bottom sliding seat is located on the top surface of the bearing drive seat 1 and is slidably connected.

[0038] A displacement positioning sliding seat 3 is installed at the bottom of the front end of the drilling and tapping structure 2 , and a displacement sliding column is slidably connected inside the displacement positioning sliding seat. The side end actuator of the displacement sliding column is installed on the internal frame surface of the bearing drive seat 1 .

[0039] A base plate is installed inside the bearing drive seat 1, and a displacement driving guide rod 9 is installed on the top of the base plate.

[0040] The side end of the displacement driving guide rod 9 is tightly connected to the side wall of the displacement positioning sliding seat 3 , and the displacement positioning sliding seat 3 is slidably connected inside the sliding groove opened on the top of the bearing driving seat 1 .

[0041] In a specific scheme, after the automatic drilling and tapping machine is started, the initial position parameters of the drilling and tapping structure 2 are first set through the above-mentioned control system according to the processing task, and then the displacement positioning sliding seat 3 is driven by the actuator inside the bearing driving seat 1 to perform preliminary lateral positioning movement along the displacement sliding column, so that the drilling and tapping mounting head 4 is close to the area to be processed of the workpiece. At the same time, the bottom sliding seat performs longitudinal sliding fine-tuning on the top surface of the bearing driving seat 1, and further accurately adjusts the position of the drilling and tapping mounting head 4 to ensure that its relative position with the workpiece is accurate. At this time, the displacement driving guide rod 9 adjusts its extension or shortening length according to the instructions of the control system, driving the displacement positioning sliding seat 3 to perform precise lateral positioning in the sliding groove opened on the top of the bearing driving seat 1, so as to determine the accurate starting position for subsequent drilling or tapping operations. When the position is determined, the spindle of the drilling and tapping structure 2 is started, driving the drill bit in the drilling and tapping mounting head 4 to rotate at high speed. At the same time, the bottom sliding seat slowly moves longitudinally on the bearing driving seat 1 according to the preset drilling feed speed, so that the drill bit gradually penetrates into the workpiece and starts the drilling operation. During the drilling process, the displacement positioning sliding seat 3 can be adjusted slightly in the lateral position according to the processing requirements under the action of the displacement driving guide rod 9 to ensure the straightness and position accuracy of the drilled hole. When the drill bit reaches the preset depth, the spindle stops rotating, the bottom sliding seat stops moving, and the processing of a drilling hole is completed. After the drilling is completed, the drilling and tapping mounting head 4 is automatically replaced with a tap. Similarly, the spindle starts to drive the tap to rotate, and the bottom sliding seat moves longitudinally again according to the preset tapping feed speed, so that the tap processes threads in the drilled hole. During the tapping process, the displacement positioning sliding seat 3 and the displacement driving guide rod 9 work together to ensure that the axis of the tap and the hole coincide with each other to prevent deviations in thread processing. The tapping depth is also accurately controlled by the control system. When the set depth is reached, the spindle stops and the tapping operation is completed.

[0042] The wiring diagram of the pulley motor structure 72, the second belt drive structure 79, the first belt drive structure 76, the pressure contact piece 790, the laser calibration sensor 791, the center detection sensor 792, the pressure sensor and the temperature sensor in the present invention is common knowledge in the art, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the pulley motor structure 72, the second belt drive structure 79, the first belt drive structure 76, the pressure contact piece 790, the laser calibration sensor 791, the center detection sensor 792, the pressure sensor and the temperature sensor will no longer be explained in detail.

[0043] The method of use and working principle of the device are as follows: first, the workpiece to be processed is placed on the automatic claw clamp adjustment fixing seat 5 on the top of the bearing drive seat 1. The automatic claw clamp adjustment fixing seat 5 automatically adjusts the clamping force and position according to the shape and size of the workpiece to ensure that the workpiece is firmly fixed in a suitable processing position. Then, after the automatic drilling and tapping machine is started, the initial position parameters of the drilling and tapping structure 2 are set through the above-mentioned control system according to the processing task. Then, the displacement positioning sliding seat 3 is driven by the actuator inside the bearing drive seat 1 to perform preliminary lateral positioning movement along the displacement sliding column, so that the drilling and tapping installation head 4 is close to the bearing drive seat 1. The workpiece is in the area to be processed. At the same time, the bottom sliding seat performs longitudinal sliding fine-tuning on the top surface of the bearing driving seat 1, and further accurately adjusts the position of the drilling and tapping mounting head 4 to ensure that its relative position with the workpiece is accurate. At this time, the displacement driving guide rod 9 adjusts its extension or shortening length according to the instructions of the control system, and drives the displacement positioning sliding seat 3 to perform precise transverse positioning in the sliding groove opened on the top of the bearing driving seat 1, so as to determine the accurate starting position for subsequent drilling or tapping operations. When the position is determined, the spindle of the drilling and tapping structure 2 is started, driving the drill bit in the drilling and tapping mounting head 4 to rotate at high speed. At the same time, the bottom sliding seat slowly moves longitudinally on the bearing driving seat 1 at a preset drilling feed speed, so that the drill bit gradually penetrates into the workpiece and starts the drilling operation. During the drilling process, the displacement positioning sliding seat 3 can make slight lateral position adjustments according to the processing requirements under the action of the displacement driving guide rod 9 to ensure the straightness and position accuracy of the drilled hole. When the drill bit reaches the preset depth, the spindle stops rotating, the bottom sliding seat stops moving, and the processing of a drilled hole is completed. After the drilling is completed, the drilling and tapping mounting head 4 is automatically replaced with a tap. Similarly, the spindle starts to drive the tap to rotate, and the bottom sliding seat moves longitudinally again at a preset tapping feed speed, so that the tap processes threads in the drilled hole. Then the pulley motor structure 72 is started to drive the driving gear 73 to rotate, and the driving gear 73 engages with the position outer ring gear 75, so that the position outer ring gear 75 rotates in the tooth groove vertical column 6, thereby The connecting frame 78 and its first belt drive structure 76 and calibration slot frame 77 and other components are driven to adjust the overall position, so that the calibration slot frame 77 is close to the workpiece, and the laser calibration sensor 791 at the bottom of the calibration slot frame 77 is used to emit a laser beam to scan and detect the initial position of the workpiece, obtain the approximate outline and position information of the workpiece, and transmit these data to the external logic controller. After the workpiece position is accurately calibrated, the drilling and tapping structure 2 starts the processing operation. According to the processing requirements, the drilling and tapping structure 2 selects a suitable drill bit or tap, and adjusts the spindle speed, feed speed and other parameters, and then performs the drilling operation. The drill bit rotates at a high speed driven by the spindle, and gradually penetrates into the workpiece along the predetermined drilling path, and drills the required hole in the workpiece. Secondly, the logic controller calculates the deviation value between the workpiece and the ideal processing position according to the data transmitted by the laser calibration sensor 791, and then,The first belt drive structure 76 and the second belt drive structure 79 are controlled to work, and the pressure contact piece 790 is driven to move by the belt transmission. The pressure sensor in the pressure contact piece 790 monitors the contact pressure in real time. When the contact end contacts the workpiece and reaches the preset pressure, the pressure sensor feeds back the signal to the logic controller. At this time, the memory metal block is slightly deformed due to the pressure, and its deformation is also recorded by the pressure sensor and transmitted to the logic controller, which further assists in determining the precise position of the workpiece. The contact adjustment formed dynamically is used to enable the pressure contact piece 790 to form contact with the other side of the processing position of the workpiece during processing. The center detection sensor 792 is used to detect the workpiece in real time. The center position of the workpiece is ensured to always remain on the central axis of the equipment during the processing, avoiding the processing accuracy problem caused by eccentricity, and feedback is given to the first belt drive structure 76, the second belt drive structure 79, and the pulley motor structure 72. Then, through the coordinated work of the laser calibration sensor 791, the pressure contact member 790 and the center detection sensor 792, the precise calibration of the workpiece position is achieved, and the position deviation is controlled within a very small range. Then, the temperature sensor in the temperature control phase change adjustment structure 86 is used to start real-time monitoring of the temperature change of the workpiece processing area. As the processing proceeds, if the temperature sensor detects that the temperature rises and exceeds the preset normal processing temperature threshold, the temperature signal The signal is transmitted to the control system of the all-in-one machine, so that the control system starts the rotating motor structure according to the received signal, and the rotating motor structure drives the driving motor structure 84 to rotate and adjust at the bottom notch end of the magnetic positioning sliding seat 83, so that the driving motor structure 84 is adjusted to a suitable angle direction, so as to perform precise positioning operation on the temperature control phase change adjustment structure 86 later, and then the driving motor structure 84 is started, and the rotating tooth 88 at the top output end drives the fan gear 89 to rotate, thereby rotating the synchronous shaft 85, and driving the temperature control phase change adjustment structure 86 to rotate as a whole to a position in close contact with the workpiece processing part. At this time, the contact end 87 of the heat conducting fin is in contact with the surface of the workpiece. When the temperature at the workpiece processing position continues to rise, the phase The phase change material column begins to undergo phase change, absorbing a large amount of heat, thereby slowing down the temperature rise of the workpiece. At the same time, the temperature control unit controls the phase change process and heat dissipation rate of the phase change material column according to the feedback data of the temperature sensor to ensure that it works within the appropriate temperature range. If the temperature continues to rise after the phase change material column absorbs a certain degree of heat, the control system will further adjust the processing parameters of the equipment, such as reducing the spindle speed and feed speed of drilling or tapping, etc., to reduce the heat generated during the processing. In addition, the contact end 87 of the heat conductive fin will also conduct part of the heat to the surrounding air during the contact process with the workpiece to assist in heat dissipation, so as to maintain the temperature of the workpiece within a reasonable range and ensure the processing accuracy.
