Description

Technical Field

[0001] The present invention relates to a workpiece surface groove processing device, which can stably rotate and drive a workpiece, and can perform high-precision surface groove spinning processing on the workpiece during the rotation process. Background Art

[0002] Existing workpieces, such as pulleys, etc., often need to be processed with corresponding workpiece surface groove processing devices to process grooves on the surface of the workpiece blank. Existing workpiece surface groove processing devices generally include a workpiece rotation driving device for rotating and driving a blank workpiece, and a spinning forming device for performing groove spinning processing on the surface of the workpiece.

[0003] Currently, most of the workpiece rotation driving devices for workpiece surface groove processing devices include a rotating base rotatably installed on the bottom side of the frame, and a lifting seat liftably installed on the upper side of the frame. The lifting seat is driven by a lifting oil cylinder to descend, so as to longitudinally and rotatably fix and clamp the blank workpiece between the lifting seat and the rotating base, and then the rotating base and the lifting seat are driven to rotate by a corresponding driving mechanism. Since most of the middle parts of the blank workpieces are provided with mounting holes, during the longitudinal clamping process, if the clamping force is low, the blank workpiece will be prone to position deviation during the spinning process; if the clamping force is high, mechanical damage is likely to be caused to the upper and lower ends of the blank workpiece.

[0004] Moreover, the spinning wheel of the existing spinning forming device for workpiece surface groove processing devices is prone to a certain degree of temperature rise during the spinning processing. Since the amount of temperature rise is relatively small compared to the temperature rise degree of other machining processes, therefore, some spinning forming devices do not directly set up a cooling system, resulting in a small amount of deformation of the spinning wheel after temperature rise, thus affecting the machining accuracy; while some spinning forming devices use the method of directly spraying coolant to cool the contact position between the spinning wheel and the workpiece. Its coolant consumption is large, and in addition, a coolant recovery and circulation system needs to be set up, so the overall processing cost is relatively high.

[0005] Therefore, the research purpose of the present invention is to design a workpiece surface groove processing device that can fix the upper and lower ends of the workpiece, and at the same time can form a complete circular tube support surface at the mounting hole of the workpiece, thereby effectively ensuring the overall clamping effect of the workpiece, and can reduce the deformation amount of the workpiece mounting hole caused by spinning processing; and can realize uniform cooling and temperature reduction treatment of the spinning wheel on the premise of low-cost investment, thereby effectively maintaining the spinning processing accuracy of the spinning wheel on the workpiece.

[0017] The atomizing cooling mechanism includes a coolant container fixedly installed on the top of the connecting piece. An ultrasonic atomizing sheet for processing the coolant into atomized liquid is fixedly installed on the inner bottom side of the coolant container. A corresponding partition is fixedly connected to the installation groove inside the spinning wheel. A corresponding guiding hole is provided in the middle of the partition, and corresponding closing plates are fixedly connected to both sides of the installation groove inside the partition respectively; A corresponding conduit is installed through the top of the connecting piece. The bottom of the conduit communicates with the installation groove inside the partition, and the top of the conduit extends to the upper side of the coolant container. A corresponding fan is fixedly installed on the upper part of the coolant container. The driving shaft of the fan is connected to the connecting shaft through transmission; A plurality of arc-shaped blade plates are rotatably arranged in the installation groove inside the partition; When the spinning wheel rotates, the plurality of arc-shaped blade plates rotate to push out the cooling atomized liquid in the installation groove to cool the spinning wheel during rotation.

[0018] A plurality of the arc-shaped blade plates are respectively fixedly connected to corresponding rotating wheels at equal intervals. The rotating wheels are rotatably installed on the connecting piece through corresponding fixed shafts; The driving shaft of the fan is connected to the fixed shaft through belt transmission, and the fixed shaft is connected to the connecting shaft through belt transmission; During the rotation of the spinning wheel, the connecting shaft drives the fixed shaft and the driving shaft to rotate respectively, so as to drive the fan to rotate to inject the atomized coolant into the installation groove along the conduit, and at the same time drive the arc-shaped blade plates to rotate, so as to push out the cooling atomized liquid in the installation groove to cool the spinning wheel during rotation.

[0019] A group of sealing plates located on the upper and lower sides of the guiding hole are fixedly connected to the inner side of the partition according to height. Corresponding magnets are fixedly connected to both sides of the sealing plate. The rotating wheel is rotatably installed on the fixed shaft through a corresponding one-way bearing. Along the rotation direction of the one-way bearing, magnetic attraction metal parts corresponding to the magnets are fixedly connected to the front side of the outer end of the arc-shaped blade plate. The distance between the ends of two or more adjacent arc-shaped blade plates is equal to the distance between the two magnets; When the spinning wheel stops rotating, under the action of the magnetic attraction between the magnetic attraction metal part and the magnet, the magnetic attraction metal part close to and facing the magnet is adsorbed and connected to the magnet, so that the arc-shaped blade plate and the sealing plate cooperate to form a seal for the guiding hole on the partition.

[0020] A coolant adding port is provided on the top of the coolant container. A corresponding cover is detachably installed at the coolant adding port. A condensate discharge hole is provided at the bottom side of the connecting piece.

[0021] The mobile driving mechanism includes a workbench and a moving seat that is horizontally movably mounted on the workbench. The fixed seat is respectively liftably mounted on the moving seat. The moving seat is driven by a horizontal oil cylinder fixedly installed on the workbench, and the fixed seat is driven by a lifting oil cylinder fixedly installed on the moving seat.

[0022] On both sides of the arc-shaped pushing plate, corresponding abutting inclined surfaces are respectively arranged to incline inwards, and on both sides of the arc-shaped pressing plate, pressing inclined surfaces adapted to the abutting inclined surfaces are respectively arranged.

[0023] The bottom parts of the arc-shaped pushing plate, the arc-shaped pressing plate, and the pushing shaft respectively extend to the lower side of the bottom end of the fixed cylinder. A plurality of fixing blocks located inside the arc-shaped pressing plate are spaced on the rotating base. Corresponding swing rods are respectively swingably mounted on the fixing blocks. When the lifting seat moves down to the in-place position to fixedly clamp the workpiece between the lifting seat and the rotating base, the bottom end of the fixed cylinder presses down on the inner end of the swing rod, so that the outer end of the swing rod fixedly presses against the bottom side of the inner side wall of the arc-shaped pressing plate. Arc-shaped rods that abut against the lower side of the arc-shaped pressing plate are respectively fixedly connected to the outer ends of the swing rods.

[0024] At the top parts of the arc-shaped pushing plate and the arc-shaped pressing plate, corresponding buffer pressing plates are respectively fixedly connected outwards in an inverted L shape. The buffer pressing plates are made of rubber material. In the middle of the lifting seat, an installation round table for connecting the fixed cylinder is integrally formed and arranged downward. The outer edge of the installation round table is located outside the fixed cylinder. When the lifting seat moves down and presses on the upper side of the buffer pressing plate, the buffer pressing plate is fixed in a squeezed state between the lifting seat and the top end of the workpiece. The outer edge of the installation round table forms a stroke limit for the inner side of the buffer pressing plate after extrusion deformation.

[0025] A corresponding guiding convex edge is arranged inwardly on the bottom side of the fixed cylinder. The pushing shaft is movably inserted into the guiding convex edge, and there is a gap between the upper side of the pushing shaft and the fixed cylinder. In the middle of the rotating base, a pushing round table for pushing against the pushing shaft is integrally formed and arranged upward. The fixing blocks are respectively arranged on the rotating base outside the pushing round table.

[0026] Advantages of the present invention:

[0027] 1) The present invention is additionally provided with a covering type inner hole limiting component. Driven by the inverted T-shaped grooves with different inclinations of the thrust shaft of the limiting driving mechanism, the arc-shaped thrust plate and the arc-shaped pressing plate can be simultaneously driven to be pushed outwards, and the moving speed of the arc-shaped pressing plate is greater than that of the arc-shaped thrust plate. When the lifting seat moves down to the in-place position and the workpiece is clamped between the lifting seat and the rotating base, the arc-shaped thrust plate and the arc-shaped pressing plate are synchronously pushed out to the in-place position, so that the arc-shaped thrust plate and the arc-shaped pressing plate form a complete circular tube supporting surface at the mounting hole of the workpiece. It can not only fix the upper and lower ends of the workpiece, but also form a complete circular tube supporting surface at the mounting hole of the workpiece, thereby effectively ensuring the overall clamping effect of the workpiece and reducing the deformation amount of the mounting hole of the workpiece caused by spinning processing.

[0028] 2) The two sides of the arc-shaped thrust plate of the present invention are respectively inclined inwards with corresponding abutting inclined surfaces, and the two sides of the arc-shaped pressing plate are respectively arranged as pressing inclined surfaces adapted to the abutting inclined surfaces. When the arc-shaped thrust plate and the arc-shaped pressing plate cooperate to form a complete circular tube supporting surface inside the mounting hole of the workpiece, part of the force on the arc-shaped thrust plate can be evenly dispersed and transferred obliquely to the arc-shaped pressing plate, so that not only the force dispersion effect during the spinning process can be improved, but also the structural stability between the arc-shaped thrust plate and the arc-shaped pressing plate during the force application process can be enhanced.

[0029] 3) Since inverted T-shaped grooves with different inclinations need to be provided on the thrust shaft to drive the sliding rods mounted on the arc-shaped thrust plate and the arc-shaped pressing plate, due to the stroke limitations between various components, the connecting rods and the sliding rods cannot be arranged at the bottoms of the arc-shaped thrust plate and the arc-shaped pressing plate, resulting in a lack of necessary support at the bottom of the circular tube supporting surface formed by the arc-shaped thrust plate and the arc-shaped pressing plate. For this reason, the present invention further provides a plurality of fixing blocks spaced apart on the rotating base and located inside the arc-shaped pressing plate, and corresponding swing rods are respectively swingably mounted on the fixing blocks. When the lifting seat moves down to the in-place position to fixedly clamp the workpiece between the lifting seat and the rotating base, the bottom end of the fixed cylinder presses the inner end of the swing rod, so that the outer end of the swing rod fixedly presses against the bottom side of the inner side wall of the arc-shaped pressing plate, thereby effectively forming a strengthening support at the bottom side of each arc-shaped pressing plate; in addition, part of the force on the arc-shaped thrust plate can be evenly dispersed and transferred obliquely to the arc-shaped pressing plate. Thus, it can effectively ensure a more stable support for the bottom of the circular tube supporting surface formed by the arc-shaped thrust plate and the arc-shaped pressing plate.

[0030] 4) At the top ends of the arc-shaped push plate and the arc-shaped pressing plate of the present invention, buffer pressing plates are respectively fixedly connected outward in an inverted L shape. In the middle of the lifting seat, an installation round table for connecting and fixing the fixed cylinder is integrally formed and arranged downward. The outer edge of the installation round table is located outside the fixed cylinder. When the lifting seat moves downward and presses on the upper side of the buffer pressing plate, the outer edge of the installation round table forms a stroke limit for the inner side of the buffer pressing plate after extrusion deformation, so as to ensure that the buffer pressing plate can be more stably fixed in an extruded state between the lifting seat and the top end of the workpiece, thereby assisting in improving the clamping effect on the workpiece.

[0031] 5) The coolant container of the coolant atomization mechanism of the present invention is fixedly installed on the top of the connecting piece. Through the addition of a conduit and a fan, during the rotation of the spinning wheel, the atomized coolant is synchronously blown into the installation groove inside the partition plate; through the addition of several arc-shaped blade plates, during the rotation of the spinning wheel, the atomized coolant is continuously pushed out of the guide holes of the partition plate, so that it directly and evenly adheres to the spinning wheel during rotation, thereby realizing uniform cooling of the spinning wheel, and realizing uniform cooling and temperature reduction treatment of the spinning wheel on the premise of low-cost investment, so as to effectively maintain the spinning processing accuracy of the spinning wheel for the workpiece.

[0032] 6) Several arc-shaped blade plates of the present invention are respectively fixedly connected to the corresponding rotating wheels at equal intervals. The rotating wheels are rotatably installed on the connecting piece through the corresponding fixed shafts; the driving shaft of the fan is connected to the fixed shaft through a belt drive method, and the fixed shaft is connected to the connecting shaft through a belt drive method. The driving power sources of several arc-shaped blade plates and the fan directly adopt the spinning wheel itself, so that during the rotation of the spinning wheel, that is, during the processing of the spinning wheel, the atomized coolant can be synchronously output to cool the spinning wheel. It can not only reduce the consumption of coolant and the energy consumption required for driving the arc-shaped blade plates and the fan, but also prevent the continuous output of coolant to the non-rotating spinning wheel, so as to prevent the overall temperature of the spinning wheel from being uneven and causing deformation, thereby ensuring the practical effect of the present invention.

[0033] 7) A group of sealing plates are fixedly connected to the inner side of the partition of the present invention according to height. Magnets are fixedly connected to both sides of the sealing plates respectively. The rotating wheel is rotatably installed on the fixed shaft through corresponding one-way bearings. Along the rotatable direction of the one-way bearing, magnetic metal parts corresponding to the magnets are fixedly connected to the front side of the outer end of the arc-shaped blade plate. The end distance between two or more adjacent arc-shaped blade plates is equal to the distance between the two magnets. When the spinning wheel stops rotating, under the action of the magnetic attraction between the magnetic metal part and the magnet, the magnetic metal part close to and facing the magnet is adsorbed and connected to the magnet, so that the arc-shaped blade plate and the sealing plate cooperate to form a closure for the guide hole on the partition. To further ensure that when the spinning wheel is not rotating, the atomized coolant is not output, thereby further ensuring the overall temperature uniformity of the spinning wheel, and further ensuring the practical effect of the present invention.

[0044] For the convenience of those skilled in the art to understand, the structure of the present invention will be further described in detail below in conjunction with the attached drawings:

[0045] Refer to Figures 1-9 , a workpiece surface groove processing device, including a frame 1, a workpiece rotation driving device 2 and a spinning forming device 3,

[0046] The workpiece rotation driving device 2 includes:

[0047] A clamping mechanism 201, including a rotating base 2011 rotatably installed on the bottom side of the frame 1 and a lifting seat 2012 movably installed on the upper side of the rotating base 2011, the lifting seat 2012 is driven by a corresponding clamping oil cylinder 2013, and the rotating base 2011 and the lifting seat 2012 are synchronously driven by a group of synchronous motors 2014;

[0048] A covering type inner hole limiting component 202, including a fixed cylinder 2021 fixedly connected to the bottom side of the lifting seat 2012, a plurality of arc-shaped pushing plates 2022 are movably arranged at equal intervals on the periphery of the fixed cylinder 2021, and arc-shaped pressing plates 2023 are movably arranged between adjacent two arc-shaped pushing plates 2022 respectively, the arc-shaped pressing plates 2023 are located inside adjacent two arc-shaped pushing plates 2022 and are arranged at intervals with the arc-shaped pushing plates 2022, and a group of connecting rods 2024 that can movably penetrate and be inserted into the fixed cylinder 2021 are fixedly connected to the arc-shaped pushing plates 2022 and the arc-shaped pressing plates 2023 respectively inwards according to height;

[0049] The limiting drive mechanism 203 includes a thrust shaft 2031 movably inserted into the fixed cylinder 2021. The top of the thrust shaft 2031 is fixedly connected to the bottom side of the lifting seat 2012 through a spiral spring 2032. Between a set of the connecting rods 2024, corresponding sliding rods 2025 are respectively and obliquely fixedly connected in an inverted T shape. The inclination angle of the sliding rod 2025 connected to the arc-shaped pressing plate 2023 is greater than the inclination angle of the sliding rod 2025 connected to the arc-shaped thrust plate 2022. A plurality of inverted T-shaped grooves 2033 for slidably connecting the sliding rods 2025 are provided on the outer side of the thrust shaft 2031;

[0050] The spinning forming device 3 includes:

[0051] A set of fixed seats 301 are respectively arranged on both sides of the workpiece rotation drive device 2 and are driven by corresponding moving drive mechanisms;

[0052] The spinning mechanism 302 includes a set of spinning wheels 3021. Corresponding connecting pieces 3022 are respectively and inwardly fixedly connected to the fixed seats 301. Corresponding installation grooves are respectively and obliquely arranged downward on the outer sides of the connecting pieces 3022. The spinning wheels 3021 are rotatably installed on the outer sides of the installation grooves through corresponding connecting shafts 3023;

[0053] The atomizing cooling mechanism 303 is used to generate atomized cooling liquid and transport the atomized cooling liquid to the surface of the spinning wheel 3021 during rotation.

[0054] The present invention is additionally provided with a covering type inner hole limiting component 202. Driven by the inverted T-shaped grooves 2033 with different inclination angles of the thrust shaft 2031 of the limiting drive mechanism 203, the arc-shaped thrust plate 2022 and the arc-shaped pressing plate 2023 can be simultaneously driven to be pushed outwards. Moreover, the moving speed of the arc-shaped pressing plate 2023 is greater than that of the arc-shaped thrust plate 2022. When the lifting seat 2012 moves down to the in-place position and the workpiece 22 is clamped between the lifting seat 2012 and the rotating base 2011, the arc-shaped thrust plate 2022 and the arc-shaped pressing plate 2023 are synchronously pushed out to the in-place position, so that the arc-shaped thrust plate 2022 and the arc-shaped pressing plate 2023 form a complete circular tube support surface at the installation hole of the workpiece 22. It can not only fix the upper and lower ends of the workpiece 22, but also form a complete circular tube support surface at the installation hole of the workpiece 22, thereby effectively ensuring the overall clamping effect of the workpiece 22 and reducing the deformation amount of the installation hole of the workpiece 22 caused by spinning processing.

[0055] The atomizing cooling mechanism 303 includes a coolant container 3031 which is fixedly installed on the top of the connecting piece 3022. An ultrasonic atomizing sheet 3032 for processing the coolant into atomized liquid is fixedly installed on the inner bottom side of the coolant container 3031. A corresponding partition plate 4 is fixedly connected to the installation groove inside the spinning wheel 3021. A corresponding guide hole 401 is provided in the middle of the partition plate 4, and corresponding closing plates 402 are fixedly connected to both sides of the installation groove inside the partition plate 4. A corresponding conduit 5 is installed through the top of the connecting piece 3022. The bottom of the conduit 5 communicates with the installation groove inside the partition plate 4, and the top of the conduit 5 extends to the upper side of the coolant container 3031. A corresponding fan 6 is fixedly installed on the upper part of the coolant container 3031. The drive shaft 601 of the fan 6 is drivingly connected to the connecting shaft 3023. A plurality of arc-shaped blade plates 7 are rotatably arranged in the installation groove inside the partition plate 4. When the spinning wheel 3021 rotates, the plurality of arc-shaped blade plates 7 rotate to push out the cooling atomized liquid in the installation groove to cool the spinning wheel 3021 during the rotation process.

[0056] The coolant container 3031 of the coolant atomizing mechanism 303 of the present invention is fixedly installed on the top of the connecting piece 3022. Through the addition of the conduit 5 and the fan 6, during the rotation of the spinning wheel 3021, the atomized coolant is synchronously blown into the installation groove inside the partition plate 4. Then, through the addition of a plurality of arc-shaped blade plates 7, during the rotation of the spinning wheel 3021, the atomized coolant is continuously pushed out of the guide hole 401 of the partition plate 4, so that it directly and evenly adheres to the spinning wheel 3021 during the rotation process, thereby realizing the uniform cooling of the spinning wheel 3021, and realizing the uniform cooling and temperature reduction treatment of the spinning wheel 3021 on the premise of low-cost investment, so as to effectively maintain the spinning processing accuracy of the spinning wheel 3021 on the workpiece 22.

[0057] The plurality of arc-shaped blade plates 7 are respectively fixedly connected to corresponding runner wheels 8 at equal intervals. The runner wheels 8 are rotatably installed on the connecting piece 3022 through corresponding fixed shafts 9. The drive shaft 601 of the fan 6 is drivingly connected to the fixed shaft 9 by a belt drive method, and the fixed shaft 9 is drivingly connected to the connecting shaft 3023 by a belt drive method. During the rotation of the spinning wheel 3021, the connecting shaft 3023 drives the fixed shaft 9 and the drive shaft 601 to rotate respectively, so as to drive the fan 6 to rotate to inject the atomized coolant into the installation groove along the conduit 5, and at the same time drive the arc-shaped blade plates 7 to rotate to push out the cooling atomized liquid in the installation groove to cool the spinning wheel 3021 during the rotation process.

[0058] A plurality of arc-shaped blade plates 7 and the driving power source of the fan 6 directly adopt the spinning wheel 3021 itself. During the rotation of the spinning wheel 3021, that is, during the processing of the spinning wheel 3021, the atomized coolant can be synchronously output to cool the spinning wheel 3021. This can not only reduce the consumption of the coolant and the energy consumption required for driving the arc-shaped blade plates 7 and the fan 6, but also prevent the continuous output of the coolant to the non-rotating spinning wheel 3021, so as to prevent the overall temperature of the spinning wheel 3021 from being uneven and causing deformation, thus ensuring the practical effect of the present invention.

[0059] A group of sealing plates 10 located on the upper and lower sides of the guide hole 401 are fixedly connected to the inner side of the partition plate 4 according to height. Magnets 11 are fixedly connected to both sides of the sealing plate 10 respectively. The runner 8 is rotatably installed on the fixed shaft 9 through corresponding one-way bearings 12. Along the rotation direction of the one-way bearing 12, magnetic metal parts 13 corresponding to the magnets 11 are fixedly connected to the front side of the outer end of the arc-shaped blade plate 7. The end spacing of the three arc-shaped blade plates 7 is equal to the spacing between the two magnets 11. When the spinning wheel 3021 stops rotating, under the action of the magnetic attraction force between the magnetic metal part 13 and the magnet 11, the magnetic metal part 13 close to and facing the magnet 11 is adsorbed and connected to the magnet 11, so that the arc-shaped blade plate 7 and the sealing plate 10 cooperate to form a closure for the guide hole 401 on the partition plate 4. To further ensure that when the spinning wheel 3021 is not rotating, the atomized coolant is not output, thereby further ensuring the overall temperature uniformity of the spinning wheel 3021 and further ensuring the practical effect of the present invention.

[0060] A coolant addition port is provided at the top of the coolant container 3031, and a corresponding cover 14 is detachably installed at the coolant addition port. A condensate discharge hole 15 is provided at the bottom side of the connecting member 3022.

[0061] The mobile driving mechanism includes a workbench 16 and a moving seat 17 that is horizontally movably installed on the workbench 16. The fixed seat 301 is respectively liftably installed on the moving seat 17. The moving seat 17 is driven by a horizontal oil cylinder 18 fixedly installed on the workbench 16, and the fixed seat 301 is driven by a lifting oil cylinder 19 fixedly installed on the moving seat 17.

[0062] Both sides of the arc-shaped pushing plate 2022 are respectively inclined inwards with corresponding abutting inclined surfaces, and both sides of the arc-shaped pressing plate 2023 are respectively formed with pressing inclined surfaces adapted to the abutting inclined surfaces. When the arc-shaped pushing plate 2022 and the arc-shaped pressing plate 2023 cooperate to form a complete circular tube supporting surface inside the mounting hole of the workpiece 22, part of the force on the arc-shaped pushing plate 2022 can be evenly dispersed and transferred obliquely to the arc-shaped pressing plate 2023, so that the force dispersion effect during the spinning process can be improved, and the structural stability between the arc-shaped pushing plate 2022 and the arc-shaped pressing plate 2023 during the force application process can be enhanced.

[0063] The bottom parts of the arc-shaped pushing plate 2022, the arc-shaped pressing plate 2023, and the pushing shaft 2031 respectively extend to the lower side of the bottom end of the fixed cylinder 2021. A plurality of fixing blocks 20 are spaced apart on the rotating base 2011 and located inside the arc-shaped pressing plate 2023. Corresponding swing rods 21 are swingably mounted on the fixing blocks 20 respectively. When the lifting seat 2012 descends in place to fixedly clamp the workpiece 22 between the lifting seat 2012 and the rotating base 2011, the bottom end of the fixed cylinder 2021 presses the inner end of the swing rod 21, so that the outer end of the swing rod 21 fixedly presses against the bottom side of the inner side wall of the arc-shaped pressing plate 2023, and arc-shaped rods 23 that abut against the lower side of the arc-shaped pressing plate 2023 are fixedly connected to the outer ends of the swing rods 21 respectively.

[0064] Since different inclination angle inverted T-shaped grooves 2033 need to be provided on the pushing shaft 2031 to drive the sliding rods 2025 mounted on the arc-shaped pushing plate 2022 and the arc-shaped pressing plate 2023, due to the stroke limitation between components, the connecting rods 2024 and the sliding rods 2025 cannot be arranged at the bottom of the arc-shaped pushing plate 2022 and the arc-shaped pressing plate 2023, resulting in a lack of necessary support at the bottom of the circular tube supporting surface formed by the arc-shaped pushing plate 2022 and the arc-shaped pressing plate 2023. For this reason, the present invention further arranges a plurality of fixing blocks 20 spaced apart on the rotating base 2011 and located inside the arc-shaped pressing plate 2023, and corresponding swing rods 21 are swingably mounted on the fixing blocks 20 respectively. When the lifting seat 2012 descends in place to fixedly clamp the workpiece 22 between the lifting seat 2012 and the rotating base 2011, the bottom end of the fixed cylinder 2021 presses the inner end of the swing rod 21, so that the outer end of the swing rod 21 fixedly presses against the bottom side of the inner side wall of the arc-shaped pressing plate 2023, thereby effectively forming a strengthening support at the bottom side of each arc-shaped pressing plate 2023; in addition, part of the force on the arc-shaped pushing plate 2022 can be evenly dispersed and transferred obliquely to the arc-shaped pressing plate 2023. Thus, it can effectively ensure a more stable support for the bottom of the circular tube supporting surface formed by the arc-shaped pushing plate 2022 and the arc-shaped pressing plate 2023.

[0065] The top ends of the arc-shaped pushing plate 2022 and the arc-shaped pressing plate 2023 are respectively fixedly connected outward in an inverted L shape with corresponding buffer pressing plates 24, and the buffer pressing plates 24 are made of rubber materials; a mounting round table 25 for connecting the fixed cylinder 2021 is integrally formed and arranged downward in the middle of the lifting seat 2012. The outer edge of the mounting round table 25 is located outside the fixed cylinder 2021. The lifting seat 2012 descends and presses on the upper side of the buffer pressing plate 24, so that the buffer pressing plate 24 is in an extrusion state and fixed between the lifting seat 2012 and the top end of the workpiece 22. The outer edge of the mounting round table 25 forms a stroke limit for the inner side of the buffer pressing plate 24 after extrusion deformation. To ensure that the buffer pressing plate can be more stably fixed in an extrusion state between the lifting seat 2012 and the top end of the workpiece 22, so as to assist in improving the clamping effect on the workpiece 22.

[0066] A corresponding guiding convex edge 26 is arranged inward at the bottom side of the fixed cylinder 2021. The pushing shaft 2031 is movably inserted into the guiding convex edge 26, and there is a gap between the upper side of the pushing shaft 2031 and the fixed cylinder 2021; a pushing round table 27 for pushing the pushing shaft 2031 is integrally formed and arranged upward in the middle of the rotating base 2011. The fixed blocks 20 are respectively arranged on the rotating base 2011 outside the pushing round table 27.

[0067] In the hydraulic system of the clamping oil cylinder 2013 in this embodiment, a pressure sensor is installed, which can directly measure the pressure change inside the clamping oil cylinder 2013, so that the pushing force of the clamping oil cylinder 2013 can be controlled within a set range value, and further control the tightening effect of the arc-shaped pushing plate 2022 and the arc-shaped pressing plate 2023. A little assembly error between components can be adapted through the deformation amount of the buffer pressing plate 24.

[0068] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
