Description

Technical Field

[0001] The invention relates to the technical field of leisure chair processing, in particular to a special punching device for leisure chair processing. Background Art

[0002] Leisure chairs are seats designed for relaxation and leisure, usually with comfortable cushions, backrests and armrests (sometimes without armrests), as well as adjustable functions (such as tilting, swivel or rocking) to meet the relaxation needs of different users. These chairs are usually placed in homes, offices, public places, outdoor gardens or terraces to provide people with a comfortable resting space. Leisure chair processing is a complex process covering multiple links such as design, material selection, manufacturing and quality control. The process of leisure chair processing includes design, material selection, cutting, assembly, grinding, coloring (or painting), quality inspection and other links. Among them, drilling holes in U-shaped tubes is a common operation in leisure chair processing.

[0003] Although the punching device in the prior art can realize continuous processing of the U-shaped tube when drilling holes in the U-shaped tube, it often requires manual loading and unloading operations, which not only increases the labor intensity of the operators, but also reduces the processing efficiency of the U-shaped tube, thereby reducing the production efficiency of the leisure chair. In addition, in order to ensure the processing quality of the U-shaped tube, the operators often spray cutting fluid to reduce the temperature of the U-shaped tube when drilling holes in the U-shaped tube. However, the spraying method can only attach the cutting fluid to the outer surface of the U-shaped tube, but cannot enter the inside of the U-shaped tube, so that the cooling effect of the cutting fluid can only be applied to the outer surface of the U-shaped tube. This causes a temperature difference between the inside and outside of the U-shaped tube during the drilling process, which is prone to problems such as larger drilling errors, increased drill bit wear, and thermal deformation of the U-shaped tube, thereby greatly reducing the processing quality of the U-shaped tube, which is not conducive to the normal production of leisure chairs and has poor practicality.

[0015] Compared with the prior art, the advantages of the present invention are: 1. The present invention can not only realize continuous drilling processing of U-shaped tubes, but also realize automatic loading and unloading and alignment before and after U-shaped tube processing through the mutual cooperation of loading and unloading mechanisms, limiting mechanisms, drilling processing mechanisms and two sets of suspension mechanisms, without the need for manual loading and unloading of U-shaped tubes and then alignment, thereby effectively improving the processing efficiency of U-shaped tubes, and because the loading and unloading steps of U-shaped tubes can be carried out synchronously, the processing efficiency of U-shaped tubes is further improved, thereby effectively improving the processing efficiency of leisure chairs.

[0016] 2. The present invention can achieve effective cooling of the U-shaped tube during drilling by setting a cooling mechanism. By setting a spraying component in the cooling mechanism, the outside of the U-shaped tube can be cooled by direct spraying, which helps to reduce the influence of heat generated during the drilling process on the outside of the U-shaped tube. At the same time, by setting an internal circulation component in the cooling mechanism, the cutting fluid can be introduced into the inside of the U-shaped tube so that it can circulate inside the U-shaped tube, thereby reducing the temperature inside the U-shaped tube. This internal and external combined cooling method can not only more effectively reduce the temperature of the U-shaped tube during the drilling process and reduce the generation of thermal deformation and thermal cracks, but also avoid the temperature difference between the inside and outside of the U-shaped tube, thereby avoiding the problem of excessive instantaneous temperature causing larger drilling errors and increased tool wear when the electric drill drills out of the U-shaped tube, thereby effectively ensuring the processing quality of the U-shaped tube. In addition, the circulation of the cutting fluid also helps to take away metal chips generated during the drilling process, thereby keeping the drilling area clean, reducing the wear of the drill bit, and effectively extending the service life of the drill bit.

[0017] 3. The present invention can adapt to the rotation caused by gravity when the U-shaped tube moves upward through the arrangement of the clamping assembly in the loading and unloading mechanism, so that the clamping arc plate will also rotate when the U-shaped tube rotates, thereby avoiding scratches on the surface of the U-shaped tube due to the fixed clamping, thereby effectively ensuring the quality of the U-shaped tube, and can reset the clamping arc plate to a horizontal state when the clamping arc plate is in an unclamped state and not in a horizontal state. This not only ensures that the clamping arc plate is in the best working position before each use, but also enables the clamping arc plate to always maintain a horizontal clamping during the subsequent clamping process, thereby further improving the stability and accuracy of the U-shaped tube clamping.

[0018] 4. The present invention, through the setting of the drainage mechanism, can allow the cutting fluid in the anti-overflow groove to enter the cavity, and enter the external filtering device outside through the pipeline, thereby completing the recovery and treatment of the cutting fluid, ensuring the cleanliness and safety of the working environment, and also improving the utilization rate of the cutting fluid. Moreover, through the setting of the collecting box in the second suspension mechanism, the cutting fluid dripping from the U-shaped tube suspended on the two groups of second fixed frames can be collected, thereby avoiding the cutting fluid from flowing freely in the working area, further maintaining the cleanliness of the working environment, and also reducing the waste of cutting fluid and improving resource utilization.

[0022] Reference Figures 1 to 3A special punching device for processing leisure chairs includes a mounting frame 1 and an operating table 2, the operating table 2 is located directly below the mounting frame 1, and an anti-overflow groove 25 is opened on the top of the operating table 2, and a first hanging mechanism and a second hanging mechanism are respectively arranged on both sides of the mounting frame 1, which are respectively used to hang the U-shaped tube to be processed and the U-shaped tube after processing, the first hanging mechanism includes two groups of first fixing frames 3, the two groups of first fixing frames 3 are located on one side of the mounting frame 1, and the two groups of first fixing frames 3 are arranged to be inclined downward in the direction close to the operating table 2, and the tops of the two groups of first fixing frames 3 are both installed with first blocking rods 6 near the operating table 2, and the second hanging mechanism includes a collecting box 4, and two groups of second fixing frames 5 are fixedly installed on the inner bottom wall of the collecting box 4, the two groups of second fixing frames 5 are located on the other side of the mounting frame 1, and the two groups of second fixing frames 5 are away from the operating table 2. It is arranged to be tilted downward, and a second blocking rod 10 is installed at the top of the two groups of second fixed frames 5 away from the position of the operating table 2. The two groups of first fixed frames 3 and the two groups of second fixed frames 5 are respectively used to hang the U-shaped tubes to be processed and the U-shaped tubes after hanging. The two groups of first blocking rods 6 and the two groups of second blocking rods 10 are respectively used to prevent the U-shaped tubes on the first fixed frames 3 from falling and to prevent the U-shaped tubes on the second fixed frames 5 from falling. The two groups of first fixed frames 3 are arranged at the direction close to the operating table 2 with a lifting mechanism for lifting the U-shaped tube in contact with the first blocking rod 6. The lifting mechanism includes a base 7, which is located between the two groups of first fixed frames 3, and a first electric telescopic rod 8 is installed at the top of the base 7. The output end of the first electric telescopic rod 8 is fixedly connected to a U-shaped support plate 9, and the U-shaped support plate 9 is located directly below the U-shaped tube in contact with the first blocking rod 6.

[0023] The U-shaped tubes to be processed are hung on two groups of first fixing frames 3. Since one end of the first fixing frame 3 fixedly connected to the first blocking rod 6 is tilted downward, multiple groups of U-shaped tubes to be processed can be tilted and stacked on the two groups of first fixing frames 3. At the same time, since one end of the second fixing frame 5 fixedly connected to the second blocking rod 10 is tilted downward, the U-shaped tubes after processing can be tilted and stacked on the two groups of second fixing frames 5.

[0024] Reference Figure 1 and Figure 4A loading and unloading mechanism is provided at the bottom end of the mounting frame 1 for realizing automatic loading and unloading of the U-shaped tube. The loading and unloading mechanism includes an adjusting component and two groups of clamping components. The adjusting component is arranged at the bottom end of the mounting frame 1, and the two groups of clamping components are arranged on the adjusting component. The adjusting component is used to adjust the position and height of the two groups of clamping components. The clamping component is used to cooperate with the adjusting component to clamp the U-shaped tube. The adjusting component includes two groups of fixed plates 11, and the two groups of fixed plates 11 are symmetrically mounted at the bottom end of the mounting frame 1, and a first driving part 12 is commonly mounted on the two groups of fixed plates 11. The first driving part 12 is the prior art, and its specific structural design is not repeated here. The two groups of fixed plates 11 are connected to two groups of slides 13 through the first driving part 12. The first driving part 12 is used to adjust the position of the two groups of slides 13. The bottom ends of the two groups of slides 13 are both installed with second electric telescopic rods 14, and the bottom ends of the two groups of second electric telescopic rods 14 are respectively connected to the two groups of clamping components.

[0025] Reference Figures 4 to 7 The clamping assembly includes a connecting plate 15, which is mounted on the bottom end of the corresponding second electric telescopic rod 14, and two groups of second driving parts 16 are symmetrically mounted on the bottom end of the connecting plate 15. The second driving part 16 is a prior art, and its specific structural design is not repeated here. Two groups of clamping plates 17 are mounted on the bottom ends of the two groups of second driving parts 16. The second driving part 16 is used to make the two groups of clamping plates 17 close to each other. Clamping grooves 18 are provided on the opposite sides of the two groups of clamping plates 17. Clamping arc plates 19 are provided in the clamping grooves 18. Two groups of trapezoidal sliders 20 are installed on the clamping arc plates 19, and the clamping arc plates 19 are slidably connected in the clamping grooves 18 through the two groups of trapezoidal sliders 20. The curvature of the clamping arc plates 19 matches the curvature of the U-shaped tube. The clamping arc plate 19 and the clamping plate 17 are jointly provided with a reset component for making the clamping arc plate 19 in an unclamped state in a horizontal state. The reset component includes a supporting arc plate 23, which is fixedly mounted on the side of the clamping plate 17 away from the clamping groove 18, and a moving disk 24 is slidably connected to the top of the supporting arc plate 23, and a connecting rope 21 and a spring 22 are fixedly connected to the moving disk 24. The end of the connecting rope 21 away from the moving disk 24 passes through the outer wall of the clamping plate 17 and is connected to the clamping arc plate 19. The two groups of trapezoidal sliders 20 on the clamping arc plate 19 are both provided with a makeshift arc groove for the connecting rope 21 to pass through. The moving disk 24 is fixedly connected to the clamping plate 17 through a spring 22, and the spring 22 cover is arranged outside the connecting rope 21.

[0026] The first driving part 12 can move the two sets of slides 13 to drive the two sets of connecting plates 15 to move, so that the two second driving parts 16 arranged on the same set of connecting plates 15 move to above the U-shaped support plate 9. At this time, the two second driving parts 16 on the other set of connecting plates 15 are located above the anti-overflow groove 25. Then, the U-shaped support plate 9 is moved upward by the extension of the first electric telescopic rod 8, which can push a set of U-shaped tubes close to the first blocking rod 6 upward. Then, the two sets of second driving parts 16 are moved downward by the second electric telescopic rod 14. , and then the second driving part 16 drives the two groups of clamping plates 17 and the clamping arc plates 19 to approach each other. Since the curvature of the clamping arc plates 19 matches the curvature of the U-shaped tube, the U-shaped tube can be clamped and fixed. Subsequently, the second driving part 16 and the U-shaped tube are driven to move upward by the second electric telescopic rod 14, and then the U-shaped support plate 9 is reset by the first electric telescopic rod 8. Since the first fixed frame 3 is inclined, the remaining U-shaped tubes to be processed will slide along the first fixed frame 3 until one group of U-shaped tubes contacts the first blocking rod 6, which is convenient for subsequent loading.

[0027] While the above process is being performed, another set of second electric telescopic rods 14 is turned on to make the connecting plate 15 connected thereto move downward, and then the drilled U-shaped tube can be clamped and fixed by the second driving part 16 and the clamping assembly, and then the U-shaped tube is moved upward by the second electric telescopic rod 14. Since the clamping arc plate 19 is slidably connected to the inner side of the clamping groove 18 through two sets of trapezoidal sliders 20, the clamping arc plate 19 can adapt to the rotation caused by gravity when the U-shaped tube moves upward, and the clamping arc plate 19 will also rotate when the U-shaped tube rotates. It can avoid the situation where scratches are left on the surface of the U-shaped tube due to the fixing and clamping of the U-shaped tube, effectively ensuring the quality of the U-shaped tube. Subsequently, the two sets of slides 13 are moved by the first driving part 12, and the processed U-shaped tube is moved above the two sets of second fixing frames 5. The second electric telescopic rod 14 is used to move the U-shaped tube downward, and then the second driving part 16 and the clamping assembly release the U-shaped tube. The U-shaped tube can fall to the two sets of second fixing frames 5 and be hung and stacked with other U-shaped tubes, thereby completing the unloading of the processed U-shaped tube.

[0028] Reference Figure 1 as well as Figures 8 to 12The operating table 2 is provided with a drainage mechanism for discharging the liquid in the anti-overflow groove 25.

[0029] When the U-shaped tube to be processed is clamped and moved toward the operating table 2, it will first be lifted and tilted with the operating table 2, so that the U-shaped tube slides tiltedly on the upper surface of the operating table 2, and then the clamped part of the U-shaped tube to be processed will move above the limit frame 26, and then the second electric telescopic rod 14 will be turned on to make the U-shaped tube to be processed move downward, so that the U-shaped tube to be processed is embedded in the upper end of the limit frame 26. At this time, the U-shaped tube to be processed is supported by two groups of support plates 28, and the U-shaped tube to be processed is limited by the limit frame 26 and the two groups of L-shaped limit plates 27. In conjunction with the above-mentioned unloading operation of the U-shaped tube, automatic loading and unloading and alignment before and after the processing of the U-shaped tube can be realized, without the need for manual loading and unloading of the U-shaped tube and then alignment, thereby effectively improving the processing efficiency of the U-shaped tube, thereby effectively improving the efficiency of the leisure chair processing.

The pushing component includes a third electric telescopic rod 29, and a welding plate is installed on the third electric telescopic rod 29. The third electric telescopic rod 29 is fixedly connected to the inner bottom wall of the anti-overflow groove 25 through the welding plate. The output end of the third electric telescopic rod 29 is connected to the extrusion bar 30. The opposite sides of the two groups of extrusion bars 30 are provided with arc grooves matching the curvature of the U-shaped tube, and the opposite sides of the two groups of extrusion bars 30 A clearance groove matching the position of the support plate 28 is provided near the bottom end. The two groups of extrusion strips 30 are fixedly connected to a fixing frame 38 at one end near the opening of the U-shaped tube. The inner height of the two groups of fixing frames 38 is consistent with the height of the U-shaped tube. A drilling assembly is provided on the side of the two groups of extrusion strips 30 away from the L-shaped limiting plate 27 for drilling holes in the U-shaped tube. The drilling assembly includes three groups of fixing seats 33. The three groups of fixing seats 33 are fixedly installed on the side of the extrusion strip 30 away from the L-shaped limiting plate 27, and a fourth electric telescopic rod 34 is installed on the three groups of fixing seats 33. The output ends of the three groups of fourth electric telescopic rods 34 are installed with an electric drill 35. The extrusion strip 30 is penetrated by a clearance hole through which the drill rod of the electric drill 35 passes.

[0031] After the loading is completed, the U-shaped tube is clamped and fixed by two groups of clamping plates 17 and clamping arc plates 19, and the U-shaped tube is limited by the limit frame 26 and two groups of L-shaped limit plates 27. Then, the extrusion bar 30, the fixed frame 38 and the shielding frame 36 are moved by the third electric telescopic rod 29, so that the fixed frame 38 is fitted with the L-shaped limit plate 27. Since the inner height of the fixed frame 38 is consistent with the height of the U-shaped tube, the U-shaped tube can be limited up and down and horizontally. At the same time, since an arc groove matching the curvature of the U-shaped tube is opened on one side of the extrusion bar 30, the extrusion bar 30 and the L-shaped limit plate 27 can clamp and fix the U-shaped tube to avoid displacement of the U-shaped tube during drilling, thereby effectively ensuring the quality of the drilling process.

[0032] Reference Figures 8 to 10A cooling mechanism is installed on the operating table 2 for cooling both inside and outside the U-shaped tube. The cooling mechanism includes two groups of connecting tubes 31. One end of the two groups of connecting tubes 31 is closed, and the other end is connected to an external cutting fluid supply device. A spraying assembly is provided on the two groups of connecting tubes 31 for spraying the cutting fluid on the opening of the U-shaped tube. The spraying assembly includes three groups of liquid outlet hoses 32. The three groups of liquid outlet hoses 32 are all installed on the corresponding connecting tubes 31, and multiple groups of bottom blocks are installed on the three groups of liquid outlet hoses 32. The three groups of liquid outlet hoses 32 are fixedly installed on the corresponding extrusion strips 30 through multiple groups of bottom blocks. Two groups of exposed grooves 37 are opened at the top of the extrusion strip 30. The two groups of exposed grooves 37 match the opening position of the U-shaped tube. The liquid outlet ends of the two groups of liquid outlet hoses 32 are located above one group of exposed grooves 37, and the liquid outlet end of the other group of liquid outlet hoses 32 is located above the other group of exposed grooves 37.

[0033] Reference Figures 8 to 11 , one of the connecting pipes 31 is provided with an internal circulation component for conveying cutting fluid to the inside of the U-shaped pipe, the internal circulation component includes a shielding frame 36, an L-shaped mounting plate 39 and a connecting hose 43, the shielding frame 36 is fixedly mounted on one side of one of the fixed frames 38, the L-shaped mounting plate 39 is fixedly mounted on one side of the other fixed frame 38, and a movable connecting component is mounted on the L-shaped mounting plate 39, the connecting hose 43 is mounted on the connecting pipe 31, and an electric valve is mounted on the connecting hose 43, and the liquid outlet end of the connecting hose 43 passes through the L-shaped mounting plate 39. The outer wall of the mounting plate 39 is connected to the movable connecting component, which is used to connect the connecting hose 43 with the inside of the U-shaped tube. The movable connecting component includes a fifth electric telescopic rod 42, which is fixedly mounted on the L-shaped mounting plate 39, and a blocking disk 40 is fixedly connected to the output end of the fifth electric telescopic rod 42, the blocking disk 40 is connected to the liquid outlet end of the connecting hose 43, and an end of the blocking disk 40 away from the fifth electric telescopic rod 42 is fixedly connected to a liquid inlet pipe 41, and the outer diameter of the liquid inlet pipe 41 corresponds to the inner diameter of the U-shaped tube.

[0034] After the U-shaped tube is clamped and fixed, since the outer diameter of the liquid inlet pipe 41 corresponds to the inner diameter of the U-shaped tube, the blocking plate 40 can be fitted with one end of the U-shaped tube by starting the fifth electric telescopic rod 42. At this time, the liquid inlet pipe 41 is embedded in the U-shaped tube, and the blocking plate 40 is used to prevent the cutting fluid from leaking out. Then, the second driving part 16 and the clamping assembly release the U-shaped tube, so that the two sets of connecting plates 15 move again to above the U-shaped support plate 9 and the limit frame 26. Since the clamping arc plate 19 is connected to the moving plate 24 by the connecting rope 21, and the moving plate 24 is connected to the clamping plate 1 A spring 22 is fixedly arranged between 7. When the clamping plate 17 and the clamping arc plate 19 are in an unclamped state, and at the same time the clamping arc plate 19 is not in a horizontal state, the elastic force of the spring 22 can push the movable plate 24 to move, so that the connecting rope 21 pulls the clamping arc plate 19 to reset, and then the clamping arc plate 19 can achieve horizontal clamping during subsequent clamping. The setting of the yielding arc grooves on the two sets of trapezoidal sliders 20 can avoid interference when the connecting rope 21 pulls the clamping arc plate 19 to reset, thereby ensuring the smooth reset process of the clamping arc plate 19.

[0035] Since the fixing seat 33 and the liquid outlet hose 32 are fixedly connected to the extrusion strip 30, the fixing seat 33 and the liquid outlet hose 32 will also move with the movement of the extrusion strip 30, and the liquid outlet ends of the three groups of liquid outlet hoses 32 match the positions of the two groups of exposed grooves 37. The cutting fluid can flow to the position where the U-shaped tube is to be punched through the multiple groups of liquid outlet hoses 32, thereby completing the cooling of the opening on the outer surface of the U-shaped tube. At the same time, the electric valve on the connecting hose 43 is opened, and the cutting fluid can enter the interior of the U-shaped tube through the connecting hose 43, the blocking disk 40 and the liquid inlet pipe 41, and flow out through the other end of the U-shaped tube. At this time, the shielding frame 36 can block the splashing of the cutting fluid when it flows out of the other end of the U-shaped tube, thereby ensuring that the cutting fluid does not cause splashing when it flows out of the U-shaped tube, keeping the working environment clean and safe (since the excess length of the liquid outlet hose 32 and the connecting hose 43 can adapt to the movement of the extrusion strip 30, the movement of the extrusion strip 30 will not affect the liquid outlet hose 32 and the connecting hose 43 The extrusion strip 30 is provided with a clearance hole through which the drill rod of the power drill 35 passes. A clearance groove matching the position of the support plate 28 is provided near the bottom end of the opposite side of the two groups of extrusion strips 30. The fifth electric telescopic rod 42 is fixedly connected to the extrusion strip 30 through the L-shaped mounting plate 39. Then the electric drill 35 is started and driven to move by the fourth electric telescopic rod 34 to complete the drilling of the U-shaped tube. The flowing cutting fluid can not only reduce the temperature of the U-shaped tube, but also flush the waste chips generated by the drilling from the surface and inside of the U-shaped tube. At the same time, when drilling the U-shaped tube, the inside and outside of the U-shaped tube can be cooled to avoid the temperature difference between the inside and outside of the U-shaped tube, thereby preventing the external cutting fluid from contacting the inner wall of the U-shaped tube when the electric drill 35 drills out from the inside of the U-shaped tube, resulting in the problem of excessive instantaneous temperature causing larger drilling errors and increased tool wear, thereby effectively ensuring the processing quality of the U-shaped tube.

[0036] After drilling is completed, the electric drill 35 is reset by the fourth electric telescopic rod 34, and the delivery of the cutting fluid is interrupted at the same time. The extrusion bar 30 is reset by the third electric telescopic rod 29, and then the U-shaped tube can be replaced by the second driving part 16, the clamping assembly and the adjusting assembly. The used cutting fluid can enter the cavity 45 through the opening opened on the bottom wall of the anti-overflow groove 25, and enter the external filtering device outside through the pipeline, thereby completing the recovery and treatment of the cutting fluid, ensuring the cleanliness and safety of the working environment, and also improving the utilization rate of the cutting fluid. The bottom end of the operating table 2 is detachably mounted with a bottom plate 44, which is convenient for cleaning the inside of the cavity 45. When the processed U-shaped tube is hung on the two groups of second fixing frames 5 and stacked with other U-shaped tubes, the dripping cutting fluid can be collected by the collecting box 4, thereby avoiding the cutting fluid from flowing freely in the working area, further maintaining the cleanliness of the working environment, and reducing the waste of cutting fluid and improving resource utilization.

[0037] In the present invention, the U-shaped tubes to be processed are hung on two groups of first fixing frames 3. Since one end of the first fixing frame 3 fixedly connected to the first blocking rod 6 is tilted downward, multiple groups of U-shaped tubes to be processed can be tilted and stacked on the two groups of first fixing frames 3. At the same time, since one end of the second fixing frame 5 fixedly connected to the second blocking rod 10 is tilted downward, the U-shaped tubes after processing can be tilted and stacked on the two groups of second fixing frames 5.

[0038] Two groups of fixed plates 11 are arranged at the bottom end of the mounting frame 1, and a first driving part 12 is arranged between the two groups of fixed plates 11, and two groups of slides 13 are arranged on the first driving part 12. It is a prior art that the two groups of slides 13 are driven to move horizontally by the first driving part 12. A second electric telescopic rod 14 is fixedly arranged at the bottom end of the slide 13, and a connecting plate 15 is fixedly connected to the bottom end of the second electric telescopic rod 14. Two second driving parts 16 are arranged at the bottom end of the connecting plate 15. When in use, the two groups of slides 13 are moved by the first driving part 12, so that the two groups of connecting plates 15 move together, so that the two second driving parts 16 arranged on the same group of connecting plates 15 move to above the U-shaped support plate 9. At this time, the two second driving parts 16 on the other group of connecting plates 15 are located above the limit frame 26. Afterwards, the U-shaped supporting plate 9 is moved upward by extending the first electric telescopic rod 8, and a group of U-shaped tubes close to the first blocking rod 6 can be pushed upward, and then the two groups of second driving parts 16 are moved downward by the second electric telescopic rod 14, and the two groups of clamping plates 17 and clamping arc plates 19 can be driven to approach each other through the second driving part 16. Since the curvature of the clamping arc plate 19 matches the curvature of the U-shaped tube, the U-shaped tube can be clamped and fixed, and then the second driving part 16 and the U-shaped tube are driven upward by the second electric telescopic rod 14, and then the U-shaped supporting plate 9 is reset by the first electric telescopic rod 8. Since the first fixed frame 3 is inclined, the remaining U-shaped tubes to be processed will slide along the first fixed frame 3 until a group of U-shaped tubes contacts the first blocking rod 6, which is convenient for subsequent loading.

[0039] While the above process is being carried out, another set of second electric telescopic rods 14 is turned on to make the connecting plate 15 connected thereto move downward, and then the U-shaped tube with the completed hole can be clamped and fixed by the second driving part 16 and the clamping assembly, and then the U-shaped tube is moved upward by the second electric telescopic rod 14. Since the clamping arc plate 19 is slidably connected to the inner side of the clamping groove 18 by two sets of trapezoidal sliders 20, the clamping arc plate 19 can adapt to the rotation caused by gravity when the U-shaped tube moves upward. When the U-shaped tube rotates, the clamping arc plate 19 will also rotate accordingly, which can avoid the situation where scratches are left on the surface of the U-shaped tube due to the fixed clamping, and effectively ensure the quality of the U-shaped tube. Then, the two sets of slides 13 are moved by the first driving part 12, and the processed U-shaped tube will move to above the two sets of second fixed frames 5, and the U-shaped tube is moved downward by the second electric telescopic rod 14, and then the second driving part 16 and the clamping assembly are turned on. The holding assembly releases the U-shaped tube, and the U-shaped tube can fall to the two groups of second fixing frames 5 for hanging and stacking with other U-shaped tubes. The dripping cutting fluid can be collected by the collecting box 4. During the movement of the slide 13, the U-shaped tube to be processed will first be lifted and tilted with the operating table 2, so that the U-shaped tube slides obliquely on the upper surface of the operating table 2, and then the clamped part of the U-shaped tube to be processed will move above the limit frame 26. Then, the second electric telescopic rod 14 is turned on to make the U-shaped tube to be processed move downward, so that the U-shaped tube to be processed is embedded in the upper end of the limit frame 26. At this time, the U-shaped tube to be processed is supported by the two groups of support plates 28, and the U-shaped tube to be processed is limited by the limit frame 26 and the two groups of L-shaped limit plates 27. Automatic loading and unloading and alignment before and after the U-shaped tube processing can be realized, and there is no need to manually take the U-shaped tube for loading and unloading and then align it, thereby effectively improving the processing efficiency of the U-shaped tube, thereby effectively improving the efficiency of the leisure chair processing.

[0040] After the loading is completed, the U-shaped tube is clamped and fixed by the two groups of clamping plates 17 and the clamping arc plates 19. At the same time, the U-shaped tube is limited by the limit frame 26 and the two groups of L-shaped limit plates 27. Then, the extrusion bar 30, the fixing frame 38 and the shielding frame 36 are moved by the third electric telescopic rod 29, so that the fixing frame 38 is fitted with the L-shaped limit plate 27. Since the inner side height of the fixing frame 38 is consistent with the height of the U-shaped tube, the U-shaped tube can be limited up and down and horizontally. At the same time, since an arc groove matching the curvature of the U-shaped tube is opened on one side of the extrusion bar 30, the extrusion bar 30 and the L-shaped limit plate 27 can clamp and fix the U-shaped tube to prevent the U-shaped tube from shifting during drilling. At the same time, since the outer diameter of the liquid inlet pipe 41 corresponds to the inner diameter of the U-shaped tube, the blocking plate 40 is fitted with one end of the U-shaped tube through the fifth electric telescopic rod 42. , so that the liquid inlet pipe 41 is embedded in the U-shaped tube, and the blocking plate 40 is used to prevent the cutting fluid from leaking out. Then the second driving part 16 and the clamping assembly release the U-shaped tube, so that the two groups of connecting plates 15 move again to above the U-shaped support plate 9 and the limit frame 26. Since the clamping arc plate 19 is connected to the movable plate 24 by a connecting rope 21, and a spring 22 is fixedly arranged between the movable plate 24 and the clamping plate 17, when the clamping plate 17 and the clamping arc plate 19 are in an unclamped state, the elastic force of the spring 22 can push the movable plate 24 to move, so that the connecting rope 21 pulls the clamping arc plate 19 to reset, so that the clamping arc plate 19 can be clamped horizontally during subsequent clamping. Both groups of trapezoidal sliders 20 are provided with a makeshift arc groove for the connecting rope 21 to pass through, and the supporting arc plate 23 is used to support the movable plate 24.

[0041] Two groups of exposed grooves 37 are provided above the extrusion strip 30, and the positions of the two groups of exposed grooves 37 match the openings and positions of the U-shaped tube. Since the fixing seat 33 and the liquid outlet hose 32 are fixedly connected to the extrusion strip 30, the fixing seat 33 and the liquid outlet hose 32 will also move with the movement of the extrusion strip 30. The liquid outlet ends of the three groups of liquid outlet hoses 32 match the positions of the two groups of exposed grooves 37. One end of the two groups of connecting tubes 31 is connected to the external cutting fluid supply equipment, and the cutting fluid can flow to the U-shaped tube through the multiple groups of liquid outlet hoses 32. At the position to be punched, the electric valve on the connecting hose 43 is opened at the same time, and the cutting fluid can enter the U-shaped tube through the connecting hose 43, the blocking plate 40 and the liquid inlet pipe 41, and flow out through the other end of the U-shaped tube. At this time, the shielding frame 36 can block the splashing of the cutting fluid when it flows out of the other end of the U-shaped tube, thereby ensuring that the cutting fluid does not splash when it flows out of the U-shaped tube, keeping the working environment clean and safe (because the excess length of the liquid outlet hose 32 and the connecting hose 43 can adapt to the movement of the extrusion strip 30, so The movement of the extrusion strip 30 will not affect the normal use of the liquid outlet hose 32 and the connecting hose 43). The extrusion strip 30 is penetrated by a clearance hole for the drill rod of the power drill 35 to pass through. The two sets of extrusion strips 30 are provided with a clearance groove matching the position of the support plate 28 near the bottom end on the opposite side. The fifth electric telescopic rod 42 is fixedly connected to the extrusion strip 30 through the L-shaped mounting plate 39. Then the electric drill 35 is started and driven to move by the fourth electric telescopic rod 34 to complete the drilling of the U-shaped tube. The flowing cutting fluid can not only reduce the temperature of the U-shaped tube, but also flush the waste chips generated by the drilling from the surface and inside of the U-shaped tube. At the same time, when drilling the U-shaped tube, the inside and outside of the U-shaped tube can be cooled to avoid the temperature difference between the inside and outside of the U-shaped tube, thereby avoiding the external cutting fluid from being difficult to contact the inner wall of the U-shaped tube when the electric drill 35 drills out from the inside of the U-shaped tube, resulting in the problem of excessive instantaneous temperature causing larger drilling errors and increased tool wear, thereby effectively ensuring the processing quality of the U-shaped tube.

[0042] After drilling is completed, the electric drill 35 is reset through the fourth electric telescopic rod 34, and the delivery of the cutting fluid is interrupted at the same time. The extrusion bar 30 is reset through the third electric telescopic rod 29, and then the U-tube can be replaced through the second driving part 16, the clamping assembly and the adjustment assembly. The used cutting fluid can enter the cavity 45 through the opening opened on the bottom wall of the anti-overflow groove 25, and enter the external filtering device outside through the pipeline, thereby completing the recovery and treatment of the cutting fluid, ensuring the cleanliness and safety of the working environment, and at the same time improving the utilization rate of the cutting fluid and reducing the production cost. The bottom end of the operating table 2 is detachably mounted with a bottom plate 44 to facilitate cleaning the inside of the cavity 45.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
