Description

Technical Field

[0001] This invention relates to the field of textile accessory assembly and processing technology, and more specifically, to an integrated drilling and processing equipment for textile accessory processing. Background Technology

[0002] As key components of textile machinery and equipment, textile accessories are mostly structural parts used for assembly and connection. Threaded holes need to be machined on the accessory body. In textile accessories, the number of machined holes is relatively small, but the requirements for machining accuracy are high. The forming of threaded holes requires two machining processes in sequence: drilling and tapping. Drilling is used to form the threaded bottom hole, and tapping is used to cut the internal thread on the inner wall of the bottom hole. Currently, drilling and tapping of textile accessories are mostly completed using drilling and tapping combination machine tools. For example, a drilling and tapping combination machine tool with Chinese patent publication number CN218776237U includes a machine base, an inner placement plate, a connecting shaft fixed at the center of the bottom end of the placement plate, an annular rack fixed at the upper end of the placement plate, a second motor fixed at the upper end of the machine base and outside the placement plate, a first gear fixed at the output end of the second motor, the first gear meshing with the annular rack, a clamping and fixing component is provided inside the placement plate, and a drilling and tapping component is also provided at the upper end of the machine base and above the placement plate. Through the overall structural cooperation, multiple workpieces can be clamped and fixed, and drilling and tapping can be performed without disassembling the workpieces. However, the drilling and tapping combination machine tools mentioned above and existing similar drilling and tapping equipment mostly have separate drilling and tapping execution structures. During the processing, it is difficult to ensure that the machining centers of the drill rod and the tapping rod coincide, which easily leads to misalignment between the bottom hole and the internal thread during processing. In addition, the misalignment will cause the tap to be subjected to additional lateral force during tapping, resulting in tap breakage and affecting processing efficiency. In view of this, there is an urgent need for an integrated drilling and machining equipment for textile accessories processing to solve the above problems. Summary of the Invention

[0003] This invention provides an integrated drilling and tapping machine for textile accessories. Through the coordinated operation of a coaxial switching machining rod assembly, a positioning support component, and a pre-inspection sensing structure, it improves the overlap between the drilling and tapping machining centers. Furthermore, it performs mechanical pre-inspection of coaxiality and anomaly feedback before the machining process, enabling integrated drilling and tapping of textile accessories. This solves the problems mentioned in the background art, namely: Textile accessories need to be drilled and tapped to make threaded holes. Existing drilling and tapping equipment is prone to drilling and tapping on different axes due to its split structure, which reduces accuracy and makes the taps easy to break.

[0004] To achieve the above objectives, the integrated drilling and machining equipment for textile accessories includes a machine body, which includes a worktable. A starting component is fixedly installed on the top side of the worktable, and a support component for clamping and fixing the workpiece is installed on the worktable. The support component has a detection hole. The output end of the starting component is connected to a processing mechanism. The processing mechanism can reciprocate relative to the worktable under the drive of the starting component. The end of the processing mechanism is provided with a processing rod group, which includes a first processing rod and a second processing rod. The first processing rod and the second processing rod are respectively used to drill and tap the workpiece, and the first processing rod and the second processing rod can switch working positions according to a preset trajectory to achieve coaxial rod changing. When the starting component drives the processing mechanism to move toward the support component, the processing rod group that is not in the working position can be pre-entered into the detection hole to pre-check the positioning accuracy of the processing through mechanical interference.

[0005] In the above technical solution, because the first processing rod and the second processing rod can achieve coaxial switching processing, and the non-working processing rod can be pre-entered into the detection hole to complete the positioning pre-inspection, the processing abnormalities caused by drilling and tapping on different axes and positioning deviations can be improved.

[0006] Based on this, the starting component includes a support rod fixedly installed on the worktable. The upper end of the support rod is fixedly installed with a driving component through a connecting frame. The movable end of the driving component is vertically facing the worktable and is used to drive the processing mechanism to move up and down.

[0007] The drive unit is stably assembled with the support rod and the connecting frame. The vertical drive method can ensure the smooth lifting and lowering of the processing mechanism, which facilitates the orderly completion of pre-inspection, drilling and tapping operations by the processing rod group.

[0008] Furthermore, the support assembly includes a processing plate mounted on the workbench and lateral clamping members symmetrically arranged on both sides of the processing plate. The processing plate is used to support the bottom of the workpiece, and the lateral clamping members are used to position and clamp the workpiece laterally.

[0009] The processing table has a support surface for supporting the workpiece and a guide surface located above the support surface. The detection hole is opened through the guide surface. The support surface and the lateral clamping member cooperate to form a multi-directional positioning space for the workpiece.

[0010] The guide surface is higher than the support surface, and the top height of the workpiece after it is clamped on the support surface is lower than the height of the guide surface.

[0011] Among them, the supporting surface and the lateral clamping parts can form multi-directional positioning constraints on the workpiece, reducing the displacement and deformation of the workpiece during processing. The structure setting of the guide surface being higher than the workpiece can provide structural conditions for the machining rod in the non-working position to be pre-entered through the detection hole for positioning and pre-inspection, ensuring the orderly execution of pre-inspection and processing actions.

[0012] In another technical solution, the processing mechanism includes a composite support plate fixedly connected to the movable end of the driving component. The composite support plate includes a first mounting plate and a second mounting plate rotatably connected to the lower end of the first mounting plate via a central pivot shaft. The first processing rod and the second processing rod are respectively mounted on both sides of the lower end of the second mounting plate. The second mounting plate achieves the switching of the working positions of the first processing rod and the second processing rod by rotation. The distances of the first processing rod and the second processing rod from the axis of the central pivot shaft are equal.

[0013] This technical solution, by mounting the first and second processing rods on the same rotatable second mounting plate and keeping the distance between the two rods and the axis of rotation consistent, allows the drilling and tapping processes to be in the same processing position after rotation switching, thus achieving coaxial processing.

[0014] The detection hole is elongated and is used to guide and pre-inspect the machining rods in non-working positions when the machining rods descend. The width and diameter of the detection hole are larger than the diameters of the first and second machining rods. There is a preset gap between the detection hole and the first and second machining rods to accommodate normal insertion within the positioning error range of the workpiece. When the positioning deviation exceeds the preset range, the machining rods in non-working positions interfere with the wall of the detection hole.

[0015] The detection hole is equipped with a sensing unit on its wall and periphery. The sensing unit is electrically connected to the starting component. When a processing rod group that is not involved in the current processing step passes through the detection hole and interferes with the sensing unit, the sensing unit sends a signal to control the starting component to stop driving.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this integrated drilling and machining equipment for textile accessories, by mounting the first machining rod and the second machining rod on the second mounting plate, and making the distances of the first machining rod and the second machining rod to the center of the central shaft equal, the tapping process can be moved to the machining position of the drilling process after the second mounting plate is rotated and switched. This reduces the cumulative positioning error caused by workpiece displacement or tool change, improves the coincidence of the drilling center and the tapping center, and reduces the misalignment of the bottom hole and the internal thread.

[0017] 2. In this integrated drilling and machining equipment for textile accessories, the workpiece is positioned and supported by the support assembly, which can offset the axial cutting force during machining to a certain extent. At the same time, during the process of the machining mechanism moving towards the workpiece, the machining rod in the non-working position can be pre-inserted into the detection hole of the guide surface. Relying on the preset clearance between the rod and the detection hole, the positioning accuracy of the workpiece and the coaxiality of the machining rod are mechanically pre-checked before the actual drilling or tapping process. If the positioning or coaxiality deviation exceeds the preset range, the machining rod assembly will mechanically interfere with the wall of the detection hole, thus reflecting the deviation in machining positioning.

[0018] 3. In this integrated drilling and machining equipment for textile accessories, a sensing unit is installed inside the detection hole wall. When the machining rod interferes with the hole wall, the sensing unit can be triggered. The sensing unit outputs a signal to control the start component to stop driving, reducing workpiece damage and tap breakage caused by continued machining due to positioning deviation, thus forming error prevention protection during the machining process.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] In the prior art, textile accessories are mostly thin-walled, irregularly shaped structural parts, which require drilling and tapping to process threaded holes to meet assembly and connection requirements. Existing drilling and tapping combination machine tools can achieve continuous drilling and tapping without disassembling the workpiece, relying on support fixtures to hold the workpiece in place and completing drilling and tapping operations in sequence. However, the drilling and tapping execution structure of such equipment is mostly set up separately, which makes it difficult to ensure that the machining centers of the drill rod and the tap rod coincide. This can easily lead to the problem of misalignment between the bottom hole and the internal thread, which not only reduces the thread machining accuracy but also easily causes the tap to break, affecting the processing efficiency. In view of this, the present invention provides an integrated drilling and machining equipment for textile accessory processing.

[0023] In view of this, see Figures 1-2 As shown, the device includes a main body 1, which includes a worktable 11. A starting component 12 is fixedly installed on the top side of the worktable 11. A support component 14 for clamping and fixing the workpiece is installed on the worktable 11. The support component 14 can provide stable positioning support for the workpiece, reducing the displacement and deformation of the workpiece during processing. A detection hole 44 is provided on the support component 14. The output end of the starting component 12 is connected to the processing mechanism 13. The processing mechanism 13 can reciprocate relative to the worktable 11 under the drive of the starting component 12. The end of the processing mechanism 13 is provided with a processing rod group 301, which includes a first processing rod 33 and a second processing rod 34. The first processing rod 33 and the second processing rod 34 are respectively used to drill and tap the workpiece. The first processing rod 33 and the second processing rod 34 can switch working positions according to a preset trajectory to achieve coaxial rod changing, which can improve the center coincidence of drilling and tapping and improve the situation of misalignment between the bottom hole and the internal thread. When the starting component 12 drives the machining mechanism 13 to move toward the support component 14, the machining rod group 301, which is not in the working position, can be pre-entered into the detection hole 44. The positioning accuracy of the machining is pre-checked through the mechanical interference state. Positioning deviation can be identified before machining is executed, reducing the possibility of workpiece damage and tap breakage.

[0024] Regarding the operation of the device body 1, the startup component 12 is disclosed, such as... Figure 3 As shown, the starting component 12 includes a support rod 21 fixedly installed on the worktable 11. The upper end of the support rod 21 is fixedly installed with a cylinder as a driving component 23 through a connecting frame 22. The movable end of the cylinder is set vertically toward the worktable 11, which can provide vertical lifting power to the processing mechanism 13, so that the processing mechanism 13 moves closer to or away from the support component 14 in a straight line, and maintains the motion stability of the processing process.

[0025] Accordingly, the support assembly 14 includes a processing plate 40 mounted on the worktable 11 and lateral clamping members 41 symmetrically arranged on both sides of the processing plate 40, see reference. Figure 2 and combined Figure 3 As shown, the processing table 40 supports the bottom of the workpiece through its supporting surface 42, and cooperates with the lateral clamping component 41 to achieve lateral positioning and clamping of the workpiece, forming a multi-directional positioning space for the workpiece. In addition, the processing table 40 is also provided with a guide surface 43 located above the support surface 42. The inspection hole 44 is opened through the guide surface 43. The height of the guide surface 43 is higher than the top height of the workpiece after clamping. Through the connection surface between the support surface 42 and the guide surface 43, combined with the two lateral clamping parts 41, the workpiece can be positioned and supported, effectively reducing some of the axial cutting force during the processing.

[0026] The aforementioned lateral clamping component 41 adopts a quick-clamping clamping structure, including a clamping body, a handle linkage mechanism, and a clamping block. The clamping body is fixed to the side of the processing table 40, and the handle linkage mechanism is connected to the clamping body and the clamping block through a hinge point. When the handle is turned, the linkage mechanism drives the clamping block to move horizontally toward the side of the workpiece and press against it. The clamping state is maintained by the self-locking characteristic of the clamp, so that the workpiece is laterally positioned on the processing table 40. It forms a multi-directional constraint with the support surface 42, providing stable workpiece positioning conditions for the pre-inspection of the processing rod assembly 301 and drilling and tapping operations.

[0027] Meanwhile, see Figure 4The processing mechanism 13 includes a composite support plate 30 fixedly connected to the movable end of the drive member 23. The composite support plate 30 consists of a first mounting plate 31 and a second mounting plate 32 rotatably connected to the lower end of the first mounting plate 31 via a central shaft 35. A rotary motor (not shown in the figure) is installed inside the first mounting plate 31. The output end of the rotary motor is connected to the central shaft 35. The first processing rod 33 and the second processing rod 34 are respectively installed on both sides of the lower end of the second mounting plate 32. Back Figure 3 It can be seen that the distance L1 between the mounting center of the first processing rod 33 and the central rotating shaft 35, and the distance L2 between the mounting center of the second processing rod 34 and the central rotating shaft 35 are equal. The rotary motor can drive the central rotating shaft 35 to rotate the second mounting plate 32 180 degrees. Figure 5 This allows for the adjustment of the positions of the first machining rod 33 and the second machining rod 34, enabling them to reach the same working position after rotational switching, thus achieving coaxial operation of drilling and tapping and improving the overlap of drilling and tapping positions.

[0028] Among them, the first processing rod 33 is a drilling processing rod, and the second processing rod 34 is a tapping processing rod.

[0029] Furthermore, the detection hole 44 is elongated and used to guide and pre-inspect the machining rod assembly 301 in the non-working position when the machining rod assembly 301 descends; and the width and diameter of the detection hole 44 are larger than the diameter of the first machining rod 33 and the second machining rod 34, and there is a preset gap between the detection hole 44 and the first machining rod 33 and the second machining rod 34 to accommodate normal insertion within the positioning error range of the workpiece. When the positioning deviation exceeds the preset range, the machining rod assembly 301 in the non-working position interferes with the hole wall of the detection hole 44.

[0030] Specifically, during the use of the equipment, such as Figure 6 and Figure 7 As shown, during the drilling process, the starting component 12 drives the machining mechanism 13 to move downwards. The second machining rod 34, which is not in the working position, will first pass through the elongated detection hole 44 of the support component 14. If the second machining rod 34 can pass through smoothly, it means that the workpiece positioning and machining path are within the normal range. At this time, combined with Figure 8 and Figure 9 As shown, the second machining rod 34 in the non-working state can be stored in the space between the bottom of the guide surface 43 and the worktable 11. This area can form a relatively independent space, reducing the direct contact between the waste generated during drilling and the surface of the second machining rod 34, making it less likely for the drilling waste to splash and adhere to the rod body and working end of the second machining rod 34, thus maintaining the dimensional accuracy and surface condition of the second machining rod 34 itself. After drilling is completed, the process switches to tapping. The second mounting plate 32 rotates 180° around the central axis 35 to achieve position change. The first processing rod 33 in the non-working position is pre-inserted into the inspection hole 44. If the first processing rod 33 can pass through smoothly, it means that the tapping position is coaxial with the previous drilling position, which can be directly verified whether the drilling and tapping coaxiality meets the processing requirements.

[0031] It should be noted that the one-sided preset gap between the detection hole 44 and the first processing rod 33 and the second processing rod 34 can be set to 0.1mm to 0.3mm. This gap range can accommodate the normal positioning errors caused by workpiece installation and equipment operation, ensuring that the non-working processing rod can smoothly pass through the detection hole 44 when the deviation is normal. At the same time, when the positioning deviation or coaxiality deviation exceeds the normal range, the processing rod will cause mechanical interference with the hole wall of the detection hole 44, which meets the structural requirements of positioning accuracy and coaxiality pre-inspection before processing. In addition, the first processing rod 33, the second processing rod 34 and the processing table 40 can be replaced and adjusted according to the hole diameter that needs to be drilled on the workpiece.

[0032] Sensing units 15 are provided both inside the detection hole 44 and on the outer wall of the opening of the detection hole 44. An electrical signal linkage is established between the sensing units 15 and the starting component 12. Figure 11 When a machining rod that is not involved in the current machining process descends and passes through the detection hole 44, and mechanically interferes with the hole wall of the detection hole 44 due to positioning deviation or coaxiality deviation exceeding the preset range, the sensing unit 15 can detect the interference state in real time and generate a corresponding electrical signal. The electrical signal is transmitted to the control loop of the starting component 12, thereby controlling the starting component 12 to stop driving the machining mechanism 13, and responding to the abnormal positioning state before the actual machining action is executed.

[0033] As is well known to those skilled in the art, the aforementioned sensing unit 15 employs a contact pressure sensor (not shown in the figure). Part of the sensor is embedded and fixed at a preset point on the inner wall of the detection hole 44, while another part of the sensor is fixedly installed on the outer wall of the opening of the detection hole 44. The sensing end face of the sensor is adapted to the inner wall of the detection hole 44 and the outer wall of the opening, respectively. The power supply and signal transmission lines of the sensor run along the inside of the processing plate 40 and the side of the worktable 11, and are finally electrically connected to the control solenoid valve of the cylinder in the starting assembly 12. The linkage control between the sensor and the driving component 23 is realized through the transmission of electrical signals.

[0034] For example: Figure 10As shown, when the equipment is in the drilling process and the starting component 12 drives the processing mechanism 13 to move downward, the second processing rod 34, which is not in operation, cannot smoothly pass through the detection hole 44 due to workpiece positioning deviation or position offset of the processing mechanism 13, and will be squeezed and interfered with the inner wall of the detection hole 44 or the outer wall of the opening. At this time, the sensing unit 15 of the inner wall of the detection hole 44 and the outer wall of the opening is triggered, and the sensing unit 15 sends an electrical signal to the starting component 12. After receiving the signal, the starting component 12 immediately stops driving the processing mechanism 13 to descend, thereby responding to the abnormal state before the drilling action is executed.

[0035] Working principle: First, place the workpiece to be processed on the support surface 42 of the processing table 40 in the support assembly 14. Move the quick clamping clamp handle of the side clamping member 41. The clamping block moves horizontally toward the side of the workpiece and presses against the workpiece through the handle linkage mechanism. The clamping state is maintained by the self-locking characteristic of the clamp, so that the workpiece forms a multi-directional positioning constraint with bottom support and side clamping on the processing table 40, providing a stable positioning foundation for subsequent pre-inspection, drilling and tapping operations. The equipment is then started. The cylinder, acting as the drive component 23 in the starting assembly 12, is stably assembled with the connecting frame 22 via the support rod 21. The moving end of the cylinder vertically outputs lifting power towards the worktable 11, driving the machining mechanism 13 to move vertically towards the support assembly 14 and begin the drilling process. The first machining rod 33 is the drilling working rod, and the second machining rod 34 is the non-working tapping rod. When the non-working second machining rod 34 descends with the machining mechanism 13, it preferentially penetrates the elongated detection hole 44 on the guide surface 43 of the machining plate 40. The detection hole 44 and the first machining rod 33 and the second machining rod 34... A preset gap is provided between the two parts. This gap can accommodate the normal positioning errors caused by workpiece installation and equipment operation. If the second processing rod 34 can pass smoothly into the detection hole 44, it means that the workpiece positioning and the movement path of the processing mechanism 13 are within the qualified range. At the same time, the non-working second processing rod 34 will enter the independent gap area between the bottom of the guide surface 43 and the worktable 11. This area can prevent the waste chips generated during the drilling process from splashing and adhering to the rod body and working end of the second processing rod 34, maintaining the dimensional accuracy and surface condition of the second processing rod 34. The cylinder continues to drive the processing mechanism 13 to descend, and the first processing rod 33 performs drilling processing on the workpiece. After the drilling process is completed, the rotary motor inside the first mounting plate 31 drives the central shaft 35 to rotate the second mounting plate 32 180 degrees. Since the distances of the first processing rod 33 and the second processing rod 34 from the axis of the central shaft 35 are equal, the two processing rods switch positions after rotation. The second processing rod 34 becomes the tapping working rod, and the first processing rod 33 becomes the non-working rod, realizing the coaxial position adjustment of drilling and tapping. After entering the tapping process, the cylinder drives the machining mechanism 13 to descend again. The first machining rod 33, which is not in working state, first passes through the detection hole 44. If the first machining rod 33 passes through the detection hole 44 smoothly, it means that the tapping position is coaxial with the previous drilling position, which meets the coaxial machining requirements. Then the second machining rod 34 performs tapping on the bottom hole of the workpiece. If, during the pre-inspection stage of drilling or tapping, the non-working machining rod interferes with the contact pressure sensor on the inner wall of the detection hole 44 or the outer wall of the opening of the detection hole 44 due to workpiece positioning deviation, position offset of the machining mechanism 13, or drilling and tapping on different axes, the sensing unit 15 will detect the mechanical interference state in real time and generate an electrical signal. The electrical signal is transmitted along the line inside the machining plate 40 and the side of the worktable 11 to the control solenoid valve of the cylinder in the starting component 12, thereby controlling the cylinder to immediately stop driving the machining mechanism 13 to descend, and responding to the abnormal positioning state before the actual drilling or tapping action is executed. After all processing steps are completed, the cylinder drives the processing mechanism 13 to reset upwards, and the side clamping part 41 is released to remove the processed workpiece, thus completing the entire set of combined processing steps of positioning pre-inspection, drilling, and coaxial tapping.
