Description

Technical Field

[0001] This application relates to the field of stud processing equipment, and in particular to a large stud processing equipment. Background Technology

[0002] Large studs are important fasteners in industrial production, widely used in heavy machinery, shipbuilding, nuclear power, petrochemicals, and other fields. Due to their large diameter, length, and weight, the manufacturing process of large studs presents many significant challenges.

[0003] In traditional production models, the transfer of large studs from the storage area to the processing equipment, as well as the unloading after processing, heavily relies on gantry cranes for hoisting operations. This method has the following main drawbacks: First, the operation process is cumbersome, requiring specialized hoisting personnel for each hoisting operation, spending a significant amount of time on processes such as binding, lifting, positioning, and unhooking, resulting in extremely high labor intensity. Second, there are significant safety hazards, as high-altitude hoisting operations pose risks such as workpiece falling and lifting equipment breakage, which can easily lead to equipment damage or personnel injuries. Third, processing accuracy is affected, as each process is located on different equipment, and each process change requires re-clamping and re-alignment. The cumulative positioning errors from multiple clampings directly affect the processing accuracy and product quality of the studs.

[0004] Chinese invention patent CN119952167B discloses an injection molding screw processing device, including a chassis. Loading and unloading sections are located on both sides of the bottom inner side of the chassis, each including a material handling mechanism and a lifting and transporting mechanism. A transfer section is located between the loading and unloading sections on both sides of the chassis. A rotary drive section is installed on the top of the chassis on both sides of the transfer section, and a displacement drive section is located on the top of the chassis on both sides of the two rotary drive sections. Tool assemblies and grinding assemblies are respectively installed on the displacement drive sections on both sides. This invention integrates thread processing and grinding into one device and achieves automated loading and unloading through the structural design of the loading and unloading sections. However, in this technical solution, the loading section is fixedly installed at the bottom of the chassis and cannot move independently. In actual production, the storage location of the workpieces to be processed is usually some distance from the processing equipment. For some factories with small production batches, the stud blanks to be processed are often scattered on the ground or storage platforms. The process of transporting the blanks from the storage location to the processing equipment still requires the use of a gantry crane or manual handling, which still consumes a lot of manpower and poses safety hazards.

[0005] In summary, existing large stud production and processing often suffers from at least one of the following problems: First, loading, unloading, and inter-process transfer all rely on gantry cranes for hoisting, which is complex to operate, labor-intensive, and poses safety hazards such as falls from heights; Second, the loading device is fixed and cannot be moved, and the transfer of workpieces from their storage location to the processing equipment still requires gantry cranes or manual handling, which consumes a lot of manpower and poses safety risks.

[0006] Based on this, those skilled in the art have proposed a large-scale stud processing equipment, which provides a new solution to the above-mentioned technical problems. Summary of the Invention

[0007] To address the problems mentioned in the background art, this application provides a large-scale stud processing equipment that enables the autonomous transfer and automated loading and unloading of stud workpieces from the storage area to the processing equipment, thereby reducing reliance on gantry cranes, reducing labor intensity and safety hazards, and improving processing accuracy.

[0008] The large-scale stud processing equipment provided in this application adopts the following technical solution: A large stud processing equipment includes a worktable, a clamping and rotating mechanism and a top cone mechanism disposed at both ends of the top of the worktable for clamping workpieces and driving them to rotate during processing, and a feeding device. The feeding device includes a feeding cart, an insert support mechanism installed inside the feeding cart for supporting the workpiece, and a driving mechanism for driving the insert support mechanism to move to pick up and put down the workpiece and feed it. The driving mechanism includes a lifting drive assembly, a horizontal displacement assembly and a rotation drive assembly. The bottom of the workbench is provided with an installation chamber, and the feeding device is detachably installed inside the installation chamber; The insert support mechanism includes a support connecting rod and a plurality of insert support plates installed on the outside of the support connecting rod. The insert support plates on both sides are staggered. The driving mechanism is used to drive the support connecting rod and the insert support plates to rotate.

[0009] By adopting the above technical solution, the feeding cart can move freely independently of the workbench and can autonomously transfer between the blank storage area and the processing equipment. The feeding cart integrates a drive mechanism with lifting, horizontal movement and rotation functions, as well as staggered insert support plates. When the feeding cart moves to the blank storage area, the drive mechanism can control the insert support plates to insert into the bottom of the heavy workpiece and scoop it up, realizing the unloading of heavy workpieces. After that, the feeding cart is pushed into the installation cavity at the bottom of the workbench, and the drive mechanism is used to automatically transport and load the workpiece between the clamping rotation mechanism and the top cone mechanism to complete the automatic clamping. In the whole process, the picking, placing, transporting and loading of the studs to be processed do not require a gantry crane, which greatly reduces labor intensity and safety hazards, and realizes the integration of feeding and processing.

[0010] Optionally, the feeding cart includes a body, with casters installed at the four corners of the bottom of the body, and a pushcart handle fixed to one side of the body; The lifting drive assembly includes a lifting plate installed on both ends of the inner side of the vehicle body and slidably disposed thereon, and a lifting threaded drive rod rotatably disposed thereon. The lifting threaded drive rod located at the same end is threadedly connected to the lifting plate. A lifting drive motor is installed at both ends of the bottom of the vehicle body, and the output end of the lifting drive motor is fixedly connected to the lifting threaded drive rod located at the same end. The horizontal displacement component includes a bidirectional threaded rod rotatably mounted on the lifting plate. A horizontal drive motor is installed at one end of the lifting plate. The output end of the horizontal drive motor is fixedly connected to the bidirectional threaded rod located at the same end. Mounting boxes are threadedly connected to the threaded sections at both ends of the bidirectional threaded rod, and the mounting boxes are slidably mounted on the corresponding lifting plates. By adopting the above technical solution, the lifting drive motor drives the lifting threaded drive rod to rotate, and through the threaded transmission, the lifting plate moves up and down along the inner side of the vehicle body, thereby achieving precise vertical displacement of the insert support mechanism; the horizontal drive motor drives the bidirectional threaded rod to rotate, and through the threaded transmission, the mounting boxes at both ends slide in opposite directions on the lifting plate, thereby achieving precise horizontal displacement of the insert support mechanism; the design of four universal wheels at the bottom allows the material supply cart to move flexibly in any direction, and the push handle makes it easy for operators to push, resulting in strong overall mobility.

[0011] Optionally, the two support connecting rods are rotatably installed between the two mounting boxes on the same side, and when the support connecting rods rotate, they can drive the insert support plate on their outer side to rotate synchronously. The rotary drive assembly includes two rotary drive rods passing through the inner sides of the mounting boxes at the same end. The rotary drive rods are rotatably mounted on the lifting plate at the same end. A rotary drive motor is mounted on the end of the lifting plate near the horizontal drive motor. The output end of the rotary drive motor is fixedly connected to the corresponding rotary drive rod. The end of the support connecting rod extends into the inner side of the mounting box and is fixed with a transmission bevel gear. A drive bevel gear is meshed with one side of the transmission bevel gear. The drive bevel gear is rotatably connected to the corresponding mounting box. A plurality of second guide grooves are provided on the outer side of the rotating drive rod. A plurality of second guide strips that are adapted to the second guide grooves are provided on the inner side of the drive bevel gear. The transmission bevel gear is slidably connected to the outer side of the rotating drive rod through the cooperation of the second guide strips and the second guide grooves. By adopting the above technical solution, the rotary drive motor drives the rotary drive rod to rotate. The rotary drive rod transmits the rotational torque to the drive bevel gear through the cooperation of the second guide groove and the second guide strip. Then, the bevel gear drives the support connecting rod and the insert support plate on it to rotate synchronously. Since the drive bevel gear and the rotary drive rod can slide relative to each other, when the mounting box is horizontally displaced under the drive of the bidirectional threaded rod, the drive bevel gear can slide along the axial direction of the rotary drive rod. This achieves independent driving of horizontal displacement and rotary drive motion, ensuring that the rotary drive function is not affected when the distance between the two mounting boxes is adjusted.

[0012] Optionally, the end faces of the insert support plates on both sides that are close to each other are inclined to form a pushing slope. An arc-shaped placement groove is provided on the insert support plate and at the end of the pushing slope. Several auxiliary conveying rollers are rotatably installed on the inner side of the top of the insert support plate. The top of the auxiliary conveying rollers is higher than the top end face of the insert support plate, so that the insert support plate and the workpiece form a rolling contact. By adopting the above technical solution, the inclined design of the pusher ramp helps the insert support plate to push the workpiece towards the arc-shaped placement groove when it is inserted into the bottom of the workpiece, reducing the insertion resistance. The arc-shaped placement groove is used to stably place and position the workpiece, preventing cylindrical workpieces from rolling off the support plate. The auxiliary conveying roller is installed on the top of the support plate and is higher than the plate surface, so that the workpiece and the support plate form a rolling contact, which greatly reduces the friction when the workpiece moves on the support plate and prevents the support plates on both sides from being stuck by the workpiece when they rotate crosswise.

[0013] Optionally, it also includes an electronic control power supply box, which is installed inside the vehicle body, and the lifting drive motor, the horizontal drive motor and the rotary drive motor are all electrically connected to the electronic control power supply box; By adopting the above technical solution, the electrical control power supply box is integrated inside the material supply vehicle body, providing unified power supply and control for all drive motors on the material supply vehicle, eliminating the need for external wiring and improving the independence and mobility of the material supply vehicle; by synchronously controlling the lifting drive motor, horizontal drive motor and rotary drive motor at both ends, the insertion support mechanism at both ends of the vehicle body is ensured to move synchronously, avoiding uneven force on the workpiece, skewing or jamming caused by asynchronous movement at both ends; the insertion, lifting, translation and loading processes are completed automatically, realizing operation automation and reducing operation difficulty.

[0014] Optionally, the system also includes a stud processing mechanism. The stud processing mechanism includes a transverse mounting base fixed to one side of the top of the worktable. A transverse drive screw is rotatably mounted inside the transverse mounting base. A transverse displacement motor is fixedly mounted at one end of the transverse mounting base. The output end of the transverse displacement motor is fixedly connected to the transverse drive screw. A transverse displacement slide is threadedly connected to the outer side of the transverse drive screw. The transverse displacement slide is slidably mounted on the transverse mounting base. A longitudinal mounting base is fixedly mounted on the transverse displacement slide. A longitudinal drive screw is rotatably connected to the inner side of the longitudinal mounting base. A longitudinal displacement motor is mounted at one end of the longitudinal mounting base. The output end of the longitudinal displacement motor is fixedly connected to the longitudinal drive screw. A longitudinal displacement slide is threadedly connected to the outer side of the longitudinal drive screw. The longitudinal displacement slide is slidably mounted on the longitudinal mounting base. A workpiece is mounted on the longitudinal displacement slide. The clamping and rotating mechanism includes a first drive cylinder installed at one end of the top of the worktable, a clamping mounting frame fixedly connected to the output end of the first drive cylinder, a three-jaw chuck rotatably connected to the transverse displacement slide, and a second rotary drive motor for driving the three-jaw chuck to rotate fixedly installed on the clamping mounting frame. The top cone mechanism includes a second drive cylinder installed on the top of the worktable at the end away from the first drive cylinder. The output end of the second drive cylinder is fixedly connected to a top cone mounting bracket. An auxiliary top cone is rotatably mounted on the top cone mounting bracket. The auxiliary top cone is coaxially arranged with the three-jaw chuck. By adopting the above technical solution, the stud processing mechanism drives the transverse and longitudinal displacement slides respectively through the transverse and longitudinal displacement motors, achieving precise displacement of the workpiece in two directions in the horizontal plane to meet the needs of different processing positions; the clamping and rotating mechanism drives the three-jaw chuck to extend and retract along the workpiece axis through the first drive cylinder to clamp one end of the workpiece, while the second rotation drive motor drives the three-jaw chuck and the workpiece to rotate, realizing the rotation drive of the stud; the top cone mechanism drives the auxiliary top cone to extend through the second drive cylinder to provide top support for the other end of the workpiece, and cooperates with the clamping and rotating mechanism to achieve a double-end stable clamping of the workpiece with one clamp and one top, effectively ensuring the axial stability and coaxiality of the workpiece during processing, thereby ensuring processing accuracy.

[0015] Optionally, there are two insert support plates on the same side, and the insert support plates on both sides are arranged to cross each other. The insert support plates are slidably connected to the corresponding support connecting rods. It also includes a pushing mechanism, which includes a slide rail fixed to the top of the worktable and located on both sides of the clamping rotation mechanism and the top cone mechanism. A pushing slider is slidably installed on the top of the slide rail. The pushing slider on the side closer to the stud processing mechanism is fixedly connected to the longitudinal mounting seat. A pushing rod is slidably installed on the inner side of the pushing slider on the side away from the stud processing mechanism. The pushing rod is used to insert into the two pushing sliders to push the corresponding insert support plate to slide along the support connecting rod. A pull handle is provided at the end of the pushing rod away from the stud processing mechanism. By adopting the above technical solution, when the push rod is inserted into the inner side of the two push sliders at the same time, the entire push mechanism is linked with the push slider on the side of the longitudinal mounting seat. At this time, when the longitudinal mounting seat moves along the workpiece axis, it can drive the push rod to move synchronously without the need for an additional power source.

[0016] Optionally, the support connecting rod is provided with a plurality of first guide grooves, and the inner side of the end of the insert support plate is provided with a plurality of first guide strips adapted to the first guide grooves. The insert support plate is slidably connected to the corresponding support connecting rod through the cooperation of the first guide strips and the first guide grooves. A plurality of auxiliary support balls are rolled and embedded on the insert support plate and inside the arc surface of the arc placement groove. The auxiliary support balls protrude from the arc surface of the arc placement groove, so that the workpiece and the arc placement groove form a rolling contact. By adopting the above technical solution, the insert support plate is slidably connected to the support connecting rod through the cooperation of the first guide strip and the first guide groove. On the one hand, when the support connecting rod rotates, the guide strip and the guide groove cooperate to transmit the rotational torque to the insert support plate, so that it rotates synchronously with the support connecting rod. The insert support plate can slide freely along the axial direction of the support connecting rod under the thrust of the push rod in the pushing mechanism, taking into account both rotational transmission and axial sliding motion modes. On the other hand, when processing the workpiece, the middle part of the workpiece can be supported by the cross support plates. The synchronous movement of the push rod and the workpiece drives the synchronous displacement of the support plate, so that the support plate always supports the rear of the processing position during processing, thereby improving the processing accuracy. The auxiliary support balls embedded in the arc-shaped placement groove are higher than the arc surface, so that when the cylindrical workpiece is placed in the arc-shaped placement groove, it contacts the balls, transforming the sliding friction between the workpiece and the arc-shaped placement groove into rolling friction, which greatly reduces the resistance to the axial movement of the support plate.

[0017] Optionally, the vehicle body is provided with docking guide plates on both sides, and docking guide grooves matching the docking guide plates are opened on the side walls of the installation chamber. Several interlocking auxiliary rollers are rotatably installed on the top and bottom of the docking guide grooves. When the docking guide plate is pushed into the installation chamber by the feeding vehicle, it rolls along the interlocking auxiliary rollers for guidance. By adopting the above technical solution, the docking guide plates on both sides of the feeding car cooperate with the docking guide grooves on both sides of the installation chamber to provide precise guidance and constraints during the process of pushing the feeding car into the installation chamber, ensuring that the feeding car can be pushed in smoothly along the predetermined trajectory, thereby greatly improving the feeding accuracy. The interlocking auxiliary rollers installed at the top and bottom of the docking guide groove transform the sliding friction between the docking guide plate and the guide groove into rolling friction, significantly reducing the pushing resistance, making the feeding car push-in process effortless and smooth, while reducing the wear of the guide surface and extending the service life.

[0018] Optionally, a positioning mechanism for positioning the feeding device is provided on the workbench at both ends of the feeding device. The positioning mechanism includes mounting blocks fixedly installed at both ends of the top of the workbench. Positioning rods are slidably installed on the inner sides of both ends of the mounting blocks. Positioning holes for insertion and cooperation with the positioning rods are opened at both ends of the vehicle body. A connecting plate is fixed at the end of the two positioning rods on the same end away from the vehicle body. A return spring is sleeved on the outside of the positioning rod. The two ends of the return spring abut against the positioning rod and the mounting block respectively. A limit plate is rotatably connected to one end of the mounting block. A snap-fit ​​notch is provided on the outside of the positioning rod. A limit slot is opened on the limit plate to fit and snap-fit ​​with the snap-fit ​​notch. By adopting the above technical solution, when the feeding cart is fully pushed into the installation chamber and reaches the predetermined position, the return spring drives the positioning rod to pop out and insert into the positioning holes at both ends of the cart body, thereby positioning and locking the feeding cart, preventing the feeding cart from shifting due to external forces during the workpiece loading process, and ensuring the relative positional accuracy between the insert support mechanism, the clamping rotation mechanism, and the top cone mechanism; the limit plate rotates and engages with the locking notch of the positioning rod, and the locking engagement between the limit slot and the locking notch further prevents the positioning rod from exiting, achieving reliable locking; when it is necessary to remove the feeding cart, manually move the limit plate to release the lock, and then pull the connecting plate to make the positioning rod overcome the spring force of the return spring and exit the positioning hole, so that the feeding cart can be pulled out of the installation chamber.

[0019] In summary, this application includes at least one of the following beneficial technical effects: The feeding device of this invention can move freely independently of the workbench. The operator can push the feeding cart to the blank storage area, and control the insert support mechanism through the drive mechanism to directly scoop up the heavy stud workpiece from the storage position. Then, the feeding cart is pushed into the installation chamber at the bottom of the workbench. The drive mechanism automatically completes the lifting and loading of the workpiece. Finally, the workpiece is transported between the clamping and rotating mechanism and the top cone mechanism to complete the clamping. The entire material picking, transfer and loading process does not require the participation of a gantry crane, which greatly reduces the labor intensity, eliminates the safety hazards caused by high-altitude hoisting, and realizes the autonomous transfer and automated loading and unloading of studs from the storage area to the processing equipment. The feeding device of this invention can be detachably installed in the mounting cavity at the bottom of the workbench, integrating feeding and processing into one unit; two insert support plates are set on the same side and are arranged crosswise on the opposite side, which are linked with the longitudinal mounting seat of the push mechanism and the stud processing mechanism, so that the insert support plate always slides synchronously with the processing position during the processing, continuously providing support for the workpiece behind the processing tool position, effectively suppressing the deflection deformation of long shaft workpieces, ensuring the overall processing accuracy and product quality of the stud, and realizing the integrated design of feeding and support.

[0042] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1-21 The present invention will now be described in further detail.

[0043] Reference Figure 1-4 This application provides a large stud processing equipment, which consists of a feeding device 1, a stud processing mechanism 2, a clamping and rotating mechanism 3, a top cone mechanism 4, a worktable 5, a pushing mechanism 6, and a positioning mechanism 7.

[0044] The top two ends of the worktable 5 are respectively equipped with a clamping and rotating mechanism 3 and a top cone mechanism 4, which are used to clamp and drive the stud workpiece to rotate; the bottom of the worktable 5 is equipped with an installation chamber 51, and the feeding device 1 is detachably installed inside the installation chamber 51 to realize the integration of feeding and processing.

[0045] Reference Figure 2-5The feeding device 1 includes a feeding cart 14, a material insertion support mechanism 11 for supporting the workpiece, a drive mechanism 13 for driving the material insertion support mechanism 11 to pick up and put down the workpiece and feed it, and an electrical control power supply box 12.

[0046] The insert support mechanism 11 includes a support connecting rod 111 and several insert support plates 112 installed on the outside of the support connecting rod 111. The insert support plates 112 on both sides are staggered. The drive mechanism 13 is used to drive the support connecting rod 111 and the insert support plates 112 to rotate, so that the insert support plates 112 on both sides cross to insert or lower the workpiece, and to drive the support connecting rod 111 to lift and move horizontally, so as to realize the picking, placing, transporting and loading of the workpiece between the clamping rotation mechanism 3 and the top cone mechanism 4.

[0047] The feeding cart 14 has casters 144 installed at the four corners of the bottom of the body 141, and a push handle 142 is fixed on one side of the body 141, allowing the feeding cart 14 to move flexibly in any direction. The electrical control power box 12 is installed on the inside of the body 141 near the push handle, providing unified power supply and control for all drive motors on the feeding cart 14.

[0048] The power control box 12 is used to independently control the lifting drive motor 131, the horizontal drive motor 135, and the rotary drive motor 114. The two lifting drive motors 131 located at both ends of the vehicle body 141 are synchronously controlled by the power control box 12, the two horizontal drive motors 135 located at both ends of the vehicle body 141 are synchronously controlled by the power control box 12, and the two rotary drive motors 114 located at both ends of the vehicle body 141 are synchronously controlled by the power control box 12.

[0049] The two lifting drive motors 131, two horizontal drive motors 135, and two rotary drive motors 114 can be independently or synchronously controlled by the electrical control power supply box 12. Specifically, the electrical control power supply box 12 can simultaneously control two of the following motors to work synchronously: either two lifting drive motors 131, two horizontal drive motors 135, or two rotary drive motors 114. It should be noted that controlling the rotation of the twin screws with dual motors and simultaneously controlling the operation of the dual motors is existing technology. This requires consideration of the motor connection method, rotation direction, speed, and their impact on the rod. In actual use, the appropriate motor type and configuration should be selected based on the required rotation speed, force, and stability. An effective control system should be designed to coordinate the rotation direction and speed of the two motors to achieve the desired rotation effect. Further details are omitted here.

[0050] Reference Figure 18-19 The vehicle body 141 is provided with docking guide plates 143 on both sides, which are used to cooperate with the docking guide grooves 52 opened on both sides of the installation chamber 51 of the workbench 5. Several interlocking auxiliary rollers 53 are rotatably installed on the top and bottom of the docking guide grooves 52. When the feeding car 14 is pushed into the installation chamber 51, the docking guide plates 143 roll along the interlocking auxiliary rollers 53 to ensure that the feeding car 14 is pushed in smoothly along the predetermined trajectory, and converts sliding friction into rolling friction to reduce the pushing resistance, while improving the docking accuracy, thereby improving the feeding accuracy.

[0051] Reference Figure 5-8 The drive mechanism 13 includes a lifting drive assembly, a horizontal displacement assembly, and a rotary drive assembly.

[0052] The lifting drive assembly includes a lifting plate 133 that is slidably installed at both ends of the inner side of the vehicle body 141 and a lifting threaded drive rod 132 that is rotatably installed. A lifting drive motor 131 is installed at both ends of the bottom of the vehicle body 141. The output end of the lifting drive motor 131 is fixedly connected to the lifting threaded drive rod 132 on the same side. The lifting threaded drive rod 132 is threadedly connected to the lifting plate 133. When the lifting drive motor 131 rotates, it drives the lifting threaded drive rod 132 to rotate, thereby driving the lifting plate 133 to move precisely up and down in the vertical direction along the inner side of the vehicle body 141.

[0053] The horizontal displacement assembly includes a bidirectional threaded rod 134 rotatably mounted on a lifting plate 133. A horizontal drive motor 135 is mounted on one end of the lifting plate 133. The output end of the horizontal drive motor 135 is fixedly connected to the bidirectional threaded rod 134 on the same side. Mounting boxes 136 are threadedly connected to the threaded sections at both ends of the bidirectional threaded rod 134. The mounting boxes 136 are slidably mounted on the corresponding lifting plate 133. When the horizontal drive motor 135 rotates, it drives the mounting boxes 136 on both sides to slide horizontally in opposite directions through the bidirectional threaded rod 134, thereby adjusting the distance between the mounting boxes 136 on both sides.

[0054] Reference Figure 7 , Figure 8The rotary drive assembly includes rotary drive rods 113 passing through the inner sides of two mounting boxes 136 at the same end. The rotary drive rods 113 are rotatably mounted on a lifting plate 133. A rotary drive motor 114 is mounted on the end of the lifting plate 133 near the horizontal drive motor 135. The output end of the rotary drive motor 114 is fixedly connected to the corresponding rotary drive rod 113. Several second guide grooves 1131 are formed on the outer side of the rotary drive rods 113. A drive bevel gear 116 is rotatably mounted inside the mounting box 136. A second guide strip 1161, adapted to the second guide grooves 1131, is provided inside the drive bevel gear 116. The drive bevel gear 116 is slidably sleeved on the outer side of the rotary drive rod 113 through the cooperation of the second guide strip 1161 and the second guide groove 1131. This allows the drive bevel gear 116 to rotate synchronously with the rotary drive rod 113 and to move freely along the axial direction of the rotary drive rod 113 when the mounting box 136 slides horizontally, thus achieving independent and non-interfering horizontal displacement and rotary drive. Two support connecting rods 111 are rotatably installed between two mounting boxes 136 on the same side. The end of the support connecting rod 111 extends into the inside of the mounting box 136 and is fixed with a transmission bevel gear 115. The transmission bevel gear 115 meshes with the drive bevel gear 116. The rotation drive motor 114 transmits the rotational torque to the support connecting rod 111 through the rotation drive rod 113, the drive bevel gear 116, and the transmission bevel gear 115, driving the support connecting rod 111 and the insert support plate 112 on it to rotate synchronously.

[0055] It should be noted that, in this embodiment, to prevent the support connecting rod (111) from rotating in the opposite direction under the weight of the workpiece, which would cause the angle of the insert support plate (112) to become unstable, a self-locking measure needs to be taken for the output end of the rotary drive motor (114). Specifically, the following two implementation methods can be adopted: Implementation Method 1: The rotary drive motor 114 is a motor with a brake function. When the rotary drive motor 114 stops running, the brake mechanism automatically clamps the motor output shaft, keeping the output shaft of the rotary drive motor 114 locked. This locks the torque to the support connecting rod 111 through the rotary drive rod 113, drive bevel gear 116, and transmission bevel gear 115, preventing the support connecting rod 111 from rotating in the opposite direction under the weight of the workpiece. This ensures that the insert support plate 112 is stably maintained at a predetermined angle position, thereby ensuring that the workpiece is always stably supported on the insert support plate 112 during material handling, transfer, and loading, and will not slip due to accidental rotation of the support connecting rod 111. Implementation Method 2: A worm gear transmission mechanism is installed between the output end of the rotary drive motor 114 and the rotary drive rod 113. The output shaft of the rotary drive motor 114 is fixedly connected to the worm, and the worm wheel is fixedly connected to the rotary drive rod 113. Because the worm gear transmission has a self-locking property—that is, the worm can drive the worm wheel to rotate, but the worm wheel cannot drive the worm in the opposite direction—when the rotary drive motor 114 stops operating, the workpiece's weight is transmitted to the worm wheel through the insert support plate 112 and the support connecting rod 111. Due to the self-locking characteristic of the worm gear, the worm wheel cannot drive the worm to reverse, thus keeping the support connecting rod 111 at its current angular position. This ensures that the insert support plate 112 stably supports the workpiece without continuous power supply, resulting in higher safety and reliability. The self-locking structure used in the above two methods to achieve the self-locking function is existing technology, and will not be elaborated on here.

[0056] Furthermore, a number of auxiliary conveying rollers 1123 are rotatably installed on the inner side of the top of the insert support plate 112. The top of the auxiliary conveying rollers 1123 is higher than the top end face of the insert support plate 112, so that the workpiece and the insert support plate 112 form rolling contact, preventing the workpiece from getting stuck when the two support plates rotate crosswise.

[0057] In an optional embodiment, the end faces of the two insert support plates 112 that are close to each other are inclined to form a pushing slope 1121. The end of the pushing slope 1121 is provided with an arc-shaped placement groove 1122. The setting of the pushing slope 1121 facilitates the insertion of the insert support plate 112 into the workpiece. At the same time, it can adapt to the situation where the axis of the feeding carriage 14 is not parallel to the axis of the workpiece during material handling, thereby improving the practicality of the feeding carriage 14. When the axis of the feeding carriage 14 is not parallel to the axis of the workpiece, when the two insert support plates 112 are close to each other, the pushing slope 1121 contacts the workpiece first and pushes the workpiece to a state where the axis is close to parallel to the workpiece of the feeding carriage 14, so as to facilitate loading and unloading. The setting of the arc-shaped placement groove 1122 is used to stably place and position the workpiece, preventing cylindrical workpieces from rolling off the support plate.

[0058] In an alternative embodiment, reference is made to... Figure 1-7 Multiple insert support plates 112 are provided on the same side. The workpiece is picked up, fed and unloaded by multiple staggered insert support plates 112. In this embodiment, after the insert support plate 112 transports the workpiece between the clamping rotation mechanism 3 and the top cone mechanism 4 and completes the clamping, the drive mechanism 13 starts to drive several insert support plates 112 to disengage from the workpiece in order to avoid interference with the processing mechanism 2 during processing.

[0059] In another alternative embodiment, refer to Figure 9Two insert support plates 112 are provided on the same side, and the insert support plates 112 on both sides are arranged crosswise. Several first guide grooves 1111 are provided on the support connecting rod 111. The inner side of the end of the insert support plate 112 is provided with a first guide strip 1125 that matches the first guide groove 1111. The insert support plate 112 is slidably installed on the outside of the support connecting rod 111 through the cooperation of the first guide strip 1125 and the first guide groove 1111, so that the insert support plate 112 can rotate synchronously with the support connecting rod 111 and slide freely in the axial direction of the support connecting rod 111.

[0060] It should be noted that, in this embodiment, after the insert support plate 112 transports the workpiece between the clamping rotation mechanism 3 and the top cone mechanism 4 and completes the clamping, the two sets of intersecting insert support plates 112 continue to support the workpiece, so as to support the rear of the workpiece processing position during processing. This can reduce the impact of unstable support at both ends due to the heavy and long workpiece, and improve the processing accuracy. On the other hand, when the two sets of insert support plates 112 support the lower two sides of the workpiece, the workpiece is located in the arc-shaped placement groove 1122. The arc-shaped placement groove 1122 simultaneously clamps the upper two sides of the workpiece, thereby greatly improving the support effect.

[0061] Furthermore, a number of auxiliary support balls 1124 are rolled and embedded on the inner side of the arc surface of the arc placement groove 1122. The top of the auxiliary support balls 1124 is higher than the arc surface of the arc placement groove 1122, so that the workpiece contacts the balls after falling into the arc placement groove 1122, thus changing the sliding friction into rolling friction and reducing the resistance when the insert support plate 112 moves axially.

[0062] Reference Figure 17 , Figure 18 The stud machining mechanism 2 includes a transverse mounting base 21 fixed to one side of the top of the worktable 5. A transverse drive screw 29 is rotatably mounted inside the transverse mounting base 21. A transverse displacement motor 22 is mounted at one end of the transverse mounting base 21. The transverse displacement motor 22 drives a transverse displacement slide 23 to slide horizontally on the transverse mounting base 21 via the transverse drive screw 29. A longitudinal mounting base 24 is fixed on the transverse displacement slide 23. A longitudinal drive screw 26 is rotatably connected inside the longitudinal mounting base 24. A longitudinal displacement motor 25 is mounted at one end of the longitudinal mounting base 24. The longitudinal displacement motor 25 drives a longitudinal displacement slide 27 to slide longitudinally on the longitudinal mounting base 24 via the longitudinal drive screw 26. A workpiece 28 is mounted on the longitudinal displacement slide 27, thereby achieving precise displacement of the workpiece 28 in two directions. The workpiece 28 can be a tool for machining threads or a grinding head for grinding after thread machining, etc.

[0063] The clamping and rotating mechanism 3 includes a first drive cylinder 31 installed at one end of the top of the worktable 5. The output end of the first drive cylinder 31 is fixedly connected to a clamping mounting frame 32. A three-jaw chuck 34 is rotatably connected to the clamping mounting frame 32, and a second rotary drive motor 33 is installed on it. The second rotary drive motor 33 drives the three-jaw chuck 34 and the clamped workpiece to rotate.

[0064] The top cone mechanism 4 includes a second drive cylinder 41 installed on the top of the worktable 5 away from the end of the first drive cylinder 31. The output end of the second drive cylinder 41 is fixedly connected to a top cone mounting bracket 42. An auxiliary top cone 43 is rotatably mounted on the top cone mounting bracket 42. The auxiliary top cone 43 is coaxially arranged with the three-jaw chuck 34. The second drive cylinder 41 extends to make the auxiliary top cone 43 press against the other end of the workpiece, which cooperates with the clamping and rotating mechanism 3 to achieve stable clamping of both ends of the workpiece.

[0065] It should be noted that in this application, the workpiece can be directly lifted to a state coaxial with the clamping rotation mechanism 3 and the top cone mechanism 4 by the feeding cart. At this time, the workpiece can be automatically clamped by the clamping rotation mechanism 3 and the top cone mechanism 4 without manual operation, which greatly improves the clamping efficiency and clamping accuracy.

[0066] Reference Figure 18 , Figure 19 The pushing mechanism 6 includes a slide rail 61 fixed to the top of the worktable 5 and located on both sides of the clamping rotation mechanism 3 and the top cone mechanism 4. A pushing slider 62 is slidably mounted on the top of the slide rail 61. The pushing slider 62 on the side closer to the stud processing mechanism 2 is fixedly connected to the longitudinal mounting seat 24, and a pushing rod 63 is slidably mounted on the inner side of the pushing slider 62 on the side away from the stud processing mechanism 2. One end of the pushing rod 63 is provided with a pull handle 64. In use, the pushing rod 63 is inserted into the inner side of both pushing sliders 62 at the same time, and the pushing rod 63 extends into the end of the corresponding insert support plate 112. When the longitudinal mounting seat 24 moves along the workpiece axial direction with the workpiece 28, the pushing slider 62 drives the pushing rod 63 and the insert support plate 112 to move axially synchronously, so that the insert support plate 112 always supports the workpiece behind the processing position. No additional power source is required, the structure is simple and efficient, and the processing accuracy is greatly improved.

[0067] Reference Figure 20 , Figure 21The positioning mechanism 7 is mounted on the workbench 5 and located at both ends of the feeding device 1, and is used to position and lock the feeding device 1. The positioning mechanism 7 includes mounting blocks 71 fixedly mounted on both ends of the top of the workbench 5. Positioning rods 73 are slidably mounted on the inner sides of both ends of the mounting blocks 71, and return springs 75 are sleeved on the outer sides of the positioning rods 73. The two ends of the return springs 75 abut against the positioning rods 73 and the mounting blocks 71, respectively. A connecting plate 74 is fixed to the end of the two positioning rods 73 on the same end away from the vehicle body 141. Positioning holes 145 are opened at both ends of the vehicle body 141. When the feeding cart 14 is fully pushed into the mounting chamber 51 and reaches the predetermined position, the return springs 75 drive the positioning rods 73 to pop out and insert into the positioning holes 145, thereby automatically positioning and initially locking the feeding cart 14. One end of the mounting block 71 is rotatably connected to a limiting plate 72. The outer side of the positioning rod 73 is provided with a locking notch 732. The limiting plate 72 is provided with a limiting groove 721 that matches the locking notch 732. The limiting plate 72 is rotated and locked into the locking notch 732. Through the locking engagement of the limiting groove 721 and the locking notch 732, the positioning rod 73 is further prevented from coming out, achieving reliable locking. When it is necessary to remove the feeding cart 14, the limiting plate 72 is manually moved to release the lock, and then the connecting plate 74 is pulled to make the positioning rod 73 overcome the elastic force of the return spring 75 and exit the positioning insertion hole 145, so that the feeding cart 14 can be pulled out from the mounting chamber 51.

[0068] The working principle of the large stud processing equipment provided by this invention is as follows: refer to Figure 10-16 First, the operator pushes the feeding trolley 14 to the blank storage area using the trolley handle 142, placing the stud blank workpiece on the storage platform or the ground. At this time, the rotary drive motor 114 drives the support connecting rod 111 to rotate, causing the two side insert support plates 112 to unfold to their initial downward-sloping position (reference). Figure 10 The horizontal drive motor 135 drives the bidirectional threaded rod 134 to rotate, adjusting the distance between the two mounting boxes 136 so that the distance between the two insert support plates 112 is slightly larger than the workpiece diameter; the lifting drive motor 131 drives the lifting plate 133 to lower to an appropriate height so that the height of the insert support plate 112 is slightly lower than the workpiece placement height; the operator pushes the feeding cart 14 towards the workpiece so that the blank workpiece to be fed is located between the two insert support plates 112, for reference. Figure 10 .

[0069] Subsequently, the horizontal drive motor 135 drives the bidirectional threaded rod 134 to rotate, causing the insert support plate 112 to insert into both sides of the bottom of the workpiece and continue to move relative to it. At the same time, the rotary drive motor 114 drives the two side support connecting rods 111 to rotate, causing the insert support plate 112 to rotate inward. The pushing inclined surface 1121 guides the workpiece to roll into the arc-shaped placement groove 1122, as shown in the reference. Figure 11 ; The workpiece is then continuously rotated until the two insert support plates 112 intersect, stably lifting the workpiece. During this process, the horizontal drive motor 135 and the lifting drive motor 131 work synchronously and collaboratively to lift the workpiece to an appropriate height. (Refer to...) Figure 13 , Figure 14 , Figure 15 During this process, the insert support plates 112 on both sides intersect each other, changing from tilting downwards to supporting the workpiece to tilting upwards to lift the workpiece. The entire material handling process does not require the use of a gantry crane. The lifting drive motor 131, the horizontal drive motor 135, and the rotary drive motor 114 are controlled by the electrical control power box 12 to automatically complete the inserting, lifting, and other processes.

[0070] After the workpiece is lifted, the operator pushes the feeding trolley 14 into the mounting chamber 51 at the bottom of the worktable 5. The docking guide plates 143 on both sides of the feeding trolley 14 roll along the docking guide grooves 52 on both sides of the mounting chamber 51, and smoothly slide into the predetermined position. After the feeding trolley 14 reaches the predetermined position, the return spring 75 drives the positioning rod 73 of the positioning mechanism 7 to automatically pop out and insert into the positioning hole 145, initially locking the feeding trolley 14. The operator then rotates the limit plate 72 to engage with the engagement notch 732, achieving reliable locking and preventing the feeding trolley 14 from shifting during the feeding process. Subsequently, the staff controlled the lifting drive motor 131 through the power control box 12 to drive the lifting plate 133 to continue to rise, raising the workpiece to a height coaxial with the clamping rotation mechanism 3 and the top cone mechanism 4; the first drive cylinder 31 pushed the clamping mounting frame 32 to make the three-jaw chuck 34 clamp one end of the workpiece, and the second drive cylinder 41 pushed the top cone mounting frame 42 to make the auxiliary top cone 43 press against the other end of the workpiece, completing the double-end stable clamping of the workpiece.

[0071] After the workpiece is clamped, the push rod 63 is simultaneously inserted into both push sliders 62. The rotary drive motor 33 drives the three-jaw chuck 34 to rotate the workpiece. The transverse displacement motor 22 drives the transverse displacement slide 23 to move laterally via the transverse drive screw 29, causing the workpiece 28 to feed laterally and perform thread machining on the workpiece surface. (Refer to...) Figure 17The longitudinal displacement motor 25 drives the longitudinal displacement slide 27 to move longitudinally via the longitudinal drive screw 26. The workpiece 28 is pushed along the workpiece axis by the longitudinal mounting seat 24. At the same time, the longitudinal mounting seat 24 drives the corresponding insert support plate 112 to slide synchronously along the workpiece axis via the push slider 62 and push rod 63, always providing support for the workpiece behind the processing position, effectively preventing the long-shaft stud from bending and deforming under the processing force, and ensuring the processing accuracy and thread quality of the entire stud. After processing, the reverse order of material handling is followed: the rotary drive motor 114 drives the insert support plate 112 to rotate and unfold, the lifting drive motor 131 drives the lifting plate 133 to descend, and the workpiece is smoothly placed down; the limit plate 72 is pulled to release the positioning lock, the connecting plate 74 is pulled out to remove the positioning insert rod 73, the feeding cart 14 is pulled out of the installation chamber 51, and the workpiece is transferred to the unloading area.

[0072] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
