Abstract
Description
Technical Field
[0001] This application relates to the field of gas-filled seal production technology, and in particular to a dynamic ring production equipment and production process. Background Technology
[0002] Air-filled seals are a common type of mechanical seal, offering advantages such as preventing media leakage, reducing friction and wear, increasing sealing reliability, and having a wide range of applications. They are widely used in industries such as chemical, petroleum, and pharmaceutical. The rotating ring in an air-filled seal is the ring that contacts the shaft or the mating surface, and it rotates synchronously with the shaft during use.
[0003] Reference Figure 1 , Figure 2 as well as Figure 3 A rotating ring includes two rotating ring bodies 0, each of which includes two semi-circular connecting rings 01. The two rotating ring bodies 0 are arranged opposite each other and connected by a conical spring 02. The conical spring 02 can compensate for friction, thereby extending the service life of the gas-filled seal. Spring mounting grooves 03 are evenly distributed on opposite sides of the rotating ring bodies 0, forming a ring around the center of the rotating ring body 0. The spring mounting grooves 03 are used to install the conical springs 02, with both ends of the conical springs 02 fixed to the inner walls of the spring mounting grooves 03 on the two rotating ring bodies 0. A receiving groove 04 is provided on the side of the rotating ring body 0. The shape of the receiving groove 04 is adapted to a shaft clamp. When installed on a shaft, the protrusion on the clamp is placed in the receiving groove 04, so that when the shaft rotates, the rotating ring body 0 can grip the shaft and rotate synchronously with the shaft.
[0004] To facilitate the connection and disconnection of the two connecting rings 01, the end face of the connecting ring 01 is provided with locating pin holes 05, screw holes 06, and easy-removal grooves 07. A cylindrical pin is connected between the locating pin holes 05, with both ends of the cylindrical pin inserted into the locating pin holes 05 on the two connecting rings 01. A fixing bolt 08 is threaded into the screw hole 06, and a nut is threaded into the end of the fixing bolt 08. One end of the fixing bolt 08 passes through the screw holes 06 on the two connecting rings 01 in sequence and is threaded into the nut, thus connecting the two connecting rings 01. The easy-removal groove 07 allows the operator to easily detach the two connecting rings 01.
[0005] When producing the aforementioned rotating rings, the factory typically uses a machining center and a mill-turning lathe to process the blanks. The machining center's worktable is equipped with a three-jaw chuck and a positioning fixture. The three-jaw chuck and positioning fixture are clamped onto the worktable by clamps. When processing the blank, it is first clamped in the three-jaw chuck, and then the cutting tool on the machining center is used to process the blank into two semicircles. After that, the semicircles are clamped in the positioning fixture for subsequent processing.
[0006] Regarding the aforementioned technologies: 1. Using clamps to position the three-jaw chuck requires operators to reposition it each time it is clamped, and each repositioning is difficult, increasing the operator's workload and making it difficult to guarantee positioning accuracy, thus compromising machining accuracy. Furthermore, the clamps and the three-jaw chuck surface have point contact, resulting in a small contact area that easily causes deformation of the chuck's outer wall, affecting the stability of the chuck when connected to the worktable during re-clamping, and consequently impacting machining accuracy. 2. When cutting the blank, operators often need to pre-draw cutting lines on its surface, and these lines must pass through the blank's center, increasing the operator's workload and making it difficult to guarantee the accuracy of the drawn lines, thus affecting machining accuracy. 3. When placing the cut semicircle on the positioning fixture, to ensure that the drilling depths of the two sections are the same, the two sections need to be horizontal, which is not easily achieved, thus easily affecting machining accuracy. In summary, these technologies increase the operator's workload and make it difficult to guarantee machining accuracy. Summary of the Invention
[0007] To reduce the workload for operators and improve processing accuracy, this application provides a dynamic ring production equipment and production process.
[0008] The technical solution for the dynamic ring production equipment provided in this application is as follows:
[0009] A dynamic ring production equipment includes a machining center, the machining center comprising:
[0010] The workbench has a cutting center position set on it.
[0011] The three-jaw chuck includes a central jaw and two side jaws. When the three-jaw chuck is mounted on the worktable, the center of the three-jaw chuck and the cutting center are on the same vertical line, and the length direction of the central jaw is parallel to the width direction of the worktable. A clearance groove is provided on the central jaw, and the clearance groove is set along the length direction of the central jaw.
[0012] The chuck positioning assembly includes a positioning latch and a limiting latch. The positioning latch is set at a fixed position on the worktable, and the limiting latch slides along the length of the worktable. The opposite side of the two is set to an arc with the same curvature as the side of the three-jaw chuck. When the three-jaw chuck is fixed on the worktable, the opposite side of the positioning latch and the limiting latch abuts against the side wall of the three-jaw chuck.
[0013] The center jaw positioning assembly includes a positioning rod, a fixing member, and a limiting member. The positioning rod is set on the side wall of the three-jaw chuck corresponding to the center jaw. The fixing member is set at a fixed position on the worktable. The limiting member slides along the worktable surface with the limiting snap-fit member. When the three-jaw chuck is fixed on the worktable, the side of the fixing member opposite to the limiting member abuts against both sides of the positioning rod, and the forces applied by the fixing member and the limiting member to the positioning rod are on the same straight line.
[0014] A positioning fixture is set on the surface of the worktable. The positioning fixture includes a horizontal clamping component and a leveling component. The horizontal clamping component is used to clamp the blank in the horizontal direction. The leveling component includes a leveling plate. The leveling plate moves vertically to press the blank downward. The positioning fixture has a slot.
[0015] By adopting the above technical solution, when using a machining center to initially cut the blank, firstly, the three-jaw chuck is placed on the worktable surface, with the side of the three-jaw chuck abutting against the positioning latch, and the side of the positioning rod abutting against the fixing member, thus initially fixing the position of the three-jaw chuck. Then, the driving limit latch moves towards the positioning latch until the positioning latch and the limit latch together clamp the three-jaw chuck, while the fixing member and the limit member together abut against the positioning rod.
[0016] According to the above technical solution, a cutting center position is pre-set on the worktable, and the position of the positioning clip is fixed according to the cutting center position. This allows the operator to easily place the three-jaw chuck on the worktable during subsequent installation, significantly reducing workload and difficulty. Then, the positioning clip and the limiting clip together hold the three-jaw chuck in place, securing it. The positioning rod is then pressed against the fixing and limiting components, fixing the position of the center jaw, facilitating the subsequent cutting of the blank in half. Therefore, the above technical solution solves the problem of cumbersome clamping of the three-jaw chuck and increased worker workload mentioned in the background technology, and offers the advantages of easy clamping and precise positioning.
[0017] In addition, by changing the point contact method of the clamp to the three-jaw chuck in the existing technology, the positioning clamp and the limiting clamp together hold the three-jaw chuck tightly, increasing the force-bearing area of the three-jaw chuck and distributing the force evenly to the side wall of the three-jaw chuck. This not only makes the installation of the three-jaw chuck more stable, but also reduces the deformation of the side wall of the three-jaw chuck.
[0018] When cutting a blank using a cutter, the blank is cut into two semicircles by moving along the width of the worktable with the cutting center as the zero point. The clearance groove allows for the cutter's movement. Pre-positioning the three-jaw chuck and center jaws prepares the blank for cutting, and the clearance groove on the center jaws facilitates cutter positioning and cutting. These mechanical modifications simplify the blank cutting process for production of the moving ring, thereby improving work efficiency.
[0019] The cut semi-circular blank is placed on the positioning fixture, with its bottom engaged in the slot. Then, the vertically driven leveling plate moves towards the cut surface of the blank, abutting against the surface before moving vertically upwards to disengage from the blank. This process facilitates leveling of the blank, ensuring that the drilling depths of the two cut surfaces are identical, thus improving machining accuracy.
[0020] In summary, the above technical solution improves the positioning part of the machining center, increases the positioning accuracy of the blank, simplifies the installation and cutting process, thereby improving cutting accuracy and efficiency, and reducing the workload of operators.
[0021] Optionally, a drive mechanism may be included, the drive mechanism comprising:
[0022] A connecting rod and a limiting snap-fit are provided on the connecting rod, and the connecting rod slides along the length of the worktable.
[0023] The mounting rod is fixed in a position on the workbench, and a drive cylinder is set in the middle. The drive cylinder is used to drive the connecting rod to move.
[0024] The clamping component, located between the connecting rod and the mounting rod, is used to clamp the three-jaw chuck tightly with the positioning and limiting components.
[0025] By adopting the above technical solution, the driving cylinder is used as the power to drive the connecting rod to move, making the movement of the limit clamping component more stable. Furthermore, the clamping component can further increase the clamping force of the positioning clamping component and the limit clamping component, thereby making the three-jaw chuck more stably installed on the worktable.
[0026] Optional, the clamping components include:
[0027] There are one or two side rods, which are symmetrically arranged on both sides of the drive cylinder with the central axis of the drive cylinder as the line of symmetry, and the ends are hinged to the mounting rod.
[0028] Side rod two, two rods, symmetrically arranged on both sides of the drive cylinder with the central axis of the drive cylinder as the line of symmetry, one end of which is hinged to one end of the side rod, and the other end is hinged to the connecting rod.
[0029] There are two intermediate rods, symmetrically arranged on both sides of the drive cylinder. One end is hinged to the hinge point of side rod one and side rod two, and the other end is hinged to the piston rod of the cylinder.
[0030] By adopting the above technical solution, the piston rod of the drive cylinder extends, pushing the hinge point between the intermediate rods towards the three-jaw chuck, until the intermediate rod is perpendicular to the drive cylinder, and side rods one and two are parallel to the drive cylinder. This not only drives the movement of the limiting latching component, but also enables the locking assembly to achieve self-locking, making the three-jaw chuck more stable when mounted on the worktable.
[0031] Optionally, the mounting rod is vertically slidably connected to a connecting plate at both ends, and a limiting groove is opened on both sides of the worktable. The shape of the limiting groove is adapted to the shape of the connecting plate. When the mounting rod is fixed on the worktable, the end of the connecting plate is inserted into a corresponding limiting groove on the worktable.
[0032] By adopting the above technical solution, when installing the entire drive mechanism on the workbench, first assemble the drive mechanism, then slide the mounting rod along the surface of the workbench until the connecting plate slides to the top of the limiting groove; drive the connecting plate vertically downward until the end of the connecting plate is inserted into the corresponding limiting groove on the workbench, and fix the mounting rod on the workbench with bolts.
[0033] The positioning of the mounting rod is achieved through the cooperation of the limiting groove and the connecting plate, which facilitates the positioning of the drive mechanism when it is reinstalled. On the one hand, it increases the installation accuracy of the drive mechanism when it is reinstalled; on the other hand, it facilitates the disassembly and maintenance of the drive mechanism.
[0034] Optionally, a T-shaped groove is provided along the surface of the worktable, and a T-shaped slider is fixed on the bottom side of the connecting rod corresponding to the T-shaped groove, and the T-shaped slider slides along the length direction of the T-shaped groove.
[0035] By adopting the above technical solution, the T-shaped slide groove serves as a motion guide for the T-shaped slider, making the connecting rod more stable when moving along the worktable surface. This also makes the movement of the limit locking component more stable, allowing all positions on the side of the limit locking component to simultaneously contact the side of the three-jaw chuck. This reduces the risk of the limit locking component contacting the side wall of the three-jaw chuck first, thus preventing the three-jaw chuck from being dislodged from its original position on the worktable due to pre-existing force applied to the side wall of the three-jaw chuck.
[0036] Optionally, both the positioning clip and the limiting clip have silicone pads of the same thickness on their adjacent sides.
[0037] By adopting the above technical solution, on the one hand, silicone has good elasticity and flexibility, and can deform under the action of extrusion pressure, thereby absorbing part of the extrusion pressure and reducing the deformation of the side wall of the three-jaw chuck caused by the positioning and limiting fasteners holding the three-jaw chuck tightly.
[0038] Optionally, the limit latch and the connecting rod are detachably connected, and the positioning latch and the worktable are detachably connected.
[0039] By adopting the above technical solution, it is easy to replace the positioning and limiting connectors with the appropriate curvature according to the size of the three-jaw chuck.
[0040] When the blank is cut into two semicircles, the jaws of the three-jaw chuck can only move towards each other to clamp the blank, but cannot hold it firmly on the chuck. Therefore, when the blank size changes significantly, it is necessary to replace the three-jaw chuck with one of different sizes for fixing. According to the above technical solution, it is convenient to replace the positioning and limiting clamps with corresponding curvatures according to the size of the three-jaw chuck, thereby ensuring the installation effect of the three-jaw chuck and improving the versatility of the drive mechanism.
[0041] Optionally, the leveling component includes:
[0042] The support plate is vertically installed on the side wall of the workbench;
[0043] A horizontal sliding frame that slides horizontally on top of a support plate;
[0044] A sliding plate slides along the length of a horizontal sliding frame. A push cylinder is provided on the sliding plate, and a flat plate is fixed to the end of the piston rod of the push cylinder.
[0045] The cylinder is a double-rod double-acting cylinder with the cylinder body fixed on the support plate. One piston rod is used to drive the horizontal sliding frame, and the other piston rod is used to drive the sliding plate.
[0046] By adopting the above technical solution, after the billet is installed on the positioning fixture, the double-rod double-acting cylinder first drives the horizontal sliding frame to move towards the billet, and then drives the sliding plate to move towards the billet. When the finding plate moves above the billet, the piston rod of the pushing cylinder extends and pushes the finding plate to move vertically downward.
[0047] After leveling is completed, the piston rod of the drive cylinder is retracted first, which drives the leveling plate to move vertically upward. The double-rod double-acting cylinder first drives the sliding plate to move away from the blank, and then drives the horizontal sliding frame to move away from the blank, so that the leveling plate can be retracted and avoids interfering with the milling cutter's machining of the blank cross-section.
[0048] Optionally, the leveling assembly includes a bottom cylinder disposed on the side wall of the workbench. The piston rod of the bottom cylinder is vertically arranged and its end is fixedly connected to the support plate. The support plate slides vertically along the side wall of the workbench.
[0049] By adopting the above technical solution, after leveling is completed, the support plate is driven vertically downward by the bottom cylinder, so that the height of the leveling component is lower than that of the horizontal clamping component, thus avoiding interference with the cutting motion of the cutting tool when the top cutting tool cuts the blank held on the horizontal clamping component.
[0050] The present application provides a method for producing dynamic rings using the following technical solution:
[0051] A dynamic ring manufacturing process, comprising:
[0052] Cutting the billet: Clamp the billet on a three-jaw chuck and cut the billet in half;
[0053] Milling the cross-section: Clamp the cut blanks onto the positioning fixture and mill the cross-section.
[0054] Drill positioning pin holes: Drill positioning pin holes in the cross-section;
[0055] Drill screw holes: Drill screw holes in the cross-section;
[0056] Milling easy-to-remove grooves: Milling easy-to-remove grooves on the cross-section;
[0057] Assemble into a complete circle: Insert the end of the locating pin into the locating pin hole on the cross-section, assemble the halved blanks into a complete circle, and then use fixing bolts to fix the two halves of the blanks.
[0058] Side cutting and cut-off: The assembled blank is clamped on a mill-turning lathe and cut off after side cutting;
[0059] Re-clamp and cut the cut surface: The cut blank is re-clamped on the mill-turning lathe and the cut surface is cut to form the moving ring body.
[0060] By adopting the above technical solution, compared to first forming the moving ring body blank and then cutting both sides of the blank one by one, the cutting procedure is simplified and work efficiency is improved. Furthermore, using an improved machining center for blank clamping and precise positioning further enhances the machining efficiency and cutting accuracy of the moving ring body.

[0071] The following is in conjunction with the appendix Figure 4-9 This application will be described in further detail.
[0072] Example 1:
[0073] Embodiment 1 of this application discloses a production equipment for a rotating ring. The rotating ring production equipment includes a machining center 1 and a turning-milling composite lathe 2.
[0074] Reference Figure 4The machining center 1 includes a worktable 11, along which a three-jaw chuck 3 and a positioning fixture 4 are arranged. A cutting center position is provided on the worktable 11. When the three-jaw chuck 3 is placed on the worktable 11, its center is aligned with the cutting center position on the same vertical line. A chuck positioning assembly 5 is provided on the worktable 11 at the position corresponding to the three-jaw chuck 3. The chuck positioning assembly 5 is detachably connected to the worktable 11, allowing the three-jaw chuck 3 to be fixed on the worktable 11.
[0075] Reference Figure 4 The workbench 11 is horizontally fixed with a base plate 12 on its top surface. The top surface of the base plate 12 is horizontally provided with several parallel T-shaped grooves 13. The length direction of the T-shaped grooves 13 is parallel to the length direction of the base plate 12.
[0076] Reference Figure 5 The chuck positioning assembly 5 includes a crossbar 51, which is positioned near the positioning fixture 4. The crossbar 51 is horizontally positioned on the top of the worktable 11, and its length direction is parallel to the width direction of the worktable 11. Several T-shaped sliders 511 are arranged along the length direction of the crossbar 51. The T-shaped sliders 511 are adapted to the shape of the T-shaped grooves 13. When the crossbar 51 is installed on the base plate 12, the T-shaped sliders 511 slide along the length direction of the T-shaped grooves 13, thereby guiding the movement of the crossbar 51 and making the movement of the crossbar 51 more stable.
[0077] Reference Figure 4 The crossbar 51 has two vertically sliding connecting plates 512 at both ends. On opposite sides of the base plate 12, corresponding to the installation positions of the crossbar 51, there are limiting grooves 513 adapted to the connecting plates 512. When the crossbar 51 is installed onto the base plate 12, the connecting plates 512 slide down to the limiting grooves 513, causing the lower end of the connecting plates 512 to insert into the limiting grooves 513. Then, the connecting plates 512 are fixed inside the limiting grooves 513 with bolts. To make the crossbar 51 more stably installed on the base plate 12, the bolts can also be screwed vertically into the crossbar 51, so that the bolt ends pass through the crossbar 51 and abut against the top of the base plate 12. Furthermore, the limiting grooves 513 limit the position of the crossbar 51 on the base plate 12.
[0078] Reference Figure 5A positioning latch 514 is provided in the middle of the crossbar 51. The positioning latch 514 can slide vertically along the crossbar 51 and is fixed to the crossbar 51 by bolts. The side of the positioning latch 514 away from the crossbar 51 is set with an arc shape with the same curvature as the side of the three-jaw chuck 3, and the positioning latch 514 can be replaced according to different sizes of the three-jaw chuck 3. A fixing member 515 is fixed on the side of the crossbar 51 where the positioning latch 514 is provided. The fixing member 515 is set with an L shape and is used to limit the angle of the three-jaw chuck 3 when it is installed on the worktable 11.
[0079] Reference Figure 6 The three-jaw chuck 3 includes a central jaw 31 and two side jaws 32. Both the central jaw 31 and the side jaws 32 are evenly distributed around the center of the three-jaw chuck 3 and slide radially along the three-jaw chuck 3. The central jaw 31 has a clearance groove 33 near the center of the three-jaw chuck 3. The clearance groove 33 is horizontal in its length direction and extends along the length direction of the central jaw 31. A positioning rod 34 is fixed on the side of the three-jaw chuck 3 at a position corresponding to the central jaw 31. The positioning rod 34 is horizontally positioned and its length direction is parallel to the length direction of the central jaw 31.
[0080] Reference Figure 5 A connecting rod 52 is slidably connected to the base plate 12. The connecting rod 52 is parallel to the crossbar 51. A T-shaped slider 511, which is adapted to the T-shaped groove 13, is fixed at the bottom side of the connecting rod 52. The T-shaped slider 511 slides along the length of the T-shaped groove 13. A limiting fastener 521 is provided on the side of the connecting rod 52 near the crossbar 51. The limiting fastener 521 is vertically slidably connected to the middle position of the connecting rod 52 and fixed by bolts. The side of the limiting fastener 521 near the positioning fastener 514 is set to an arc shape with the same curvature as the side of the three-jaw chuck 3. When the three-jaw chuck 3 is installed on the worktable 11, the positioning latch 514 and the limiting latch 521 tightly hold the three-jaw chuck 3, changing the point contact method of the clamp to the three-jaw chuck 3 in the prior art. The positioning latch 514 and the limiting latch 521 jointly hold the three-jaw chuck 3, increasing the force-bearing area of the three-jaw chuck 3 and distributing the force evenly to the side wall of the three-jaw chuck 3. This makes the installation of the three-jaw chuck 3 more stable and reduces the deformation of the side wall of the three-jaw chuck 3.
[0081] Reference Figure 5 In addition, silicone pads 522 of the same thickness are fixed on the side of the positioning clip 514 and the limiting clip 521 that are close to each other, so as to absorb part of the compressive force when the three-jaw chuck 3 is gripped, and reduce the deformation caused by the compression of the side wall of the three-jaw chuck 3 due to the gripping of the positioning clip 514 and the limiting clip 521.
[0082] Reference Figure 5 A limiting member 523 is fixed on the side of the connecting rod 52 corresponding to the positioning rod 34. The limiting member 523 is L-shaped, the same as the fixing member 515. When the limiting member 523 and the fixing member 515 abut against the positioning rod 34, the fixing member 515 and the limiting member 523 are symmetrical with respect to the positioning rod 34. The positioning member is clamped by the limiting member 523 and the fixing member 515, thereby limiting the specific position of the central claw 31.
[0083] Reference Figure 5 A drive mechanism 6 is provided on the connecting rod 52, which can drive the connecting rod 52 to move horizontally towards or away from the three-jaw chuck 3. The drive mechanism 6 includes a mounting rod 61 and a clamping assembly 62. The mounting rod 61 is set parallel to the crossbar 51. A T-shaped slider 511 is fixed on the bottom side of the mounting rod 61 at the position corresponding to the T-shaped slide groove 13. The T-shaped slider 511 slides along the length direction of the T-shaped slide groove 13, thereby facilitating the installation of the mounting rod 61 onto the base plate 12. The two ends of the mounting rod 61 are vertically slidably connected to a connecting plate 611. A limiting groove 612 adapted to the shape of the connecting plate 611 is opened on the base plate 12 at the installation position corresponding to the mounting rod 611. When the connecting plate 611 slides to the position of the limiting groove 612, the connecting plate 611 slides vertically, so that the end of the connecting plate 611 enters the interior of the limiting groove 612, and the connecting plate 611 is fixed in the limiting groove 612 by bolts. To make the mounting rod 61 more stable when fixed on the workbench 11, the bolt can be screwed vertically into the mounting rod 61 so that the end of the bolt passes through the mounting rod 61 and abuts against the base plate 12.
[0084] Reference Figure 7 A drive cylinder 63 is horizontally fixed in the middle of the mounting rod 61, and the piston rod of the drive cylinder 63 extends horizontally through the mounting rod 61 toward the connecting rod 52. The clamping assembly 62 includes two side rods 621, two side rods 622, and two intermediate rods 623. Side rods 621 are symmetrically arranged on both sides of the drive cylinder 63 with the central axis as the line of symmetry. One end is hinged to the side wall of the mounting rod 61, and the other end is hinged to the end of side rod 622. Side rods 622 are also symmetrically arranged on both sides of the drive cylinder 63 with the central axis as the line of symmetry. The end away from side rod 621 is hinged to the side wall of the connecting rod 52. The intermediate rods 623 are symmetrically arranged on both sides of the drive cylinder 63, with one end hinged to the piston rod of the cylinder and the other end extending in a mutually distancing direction, and hinged to the hinge points of side rods 621 and 622 respectively.
[0085] The piston rod of the drive cylinder 63 extends, pushing the hinge point between the intermediate rods 623 towards the three-jaw chuck 3, until the intermediate rod 623 is perpendicular to the drive cylinder 63, and the side rods 621 and 622 are parallel to the drive cylinder 63. This drives the limit locking member 521 to move, and the locking assembly 62 achieves self-locking, making the three-jaw chuck 3 more stable when mounted on the worktable 11.
[0086] Reference Figure 4 The positioning fixture 4 includes a leveling component 41 and a horizontal clamping component 6242. The horizontal clamping component 6242 includes a mounting base 421 with a slot 422 along its length, positioned at the center of the mounting base 421. A clamping block 423 is slidably connected along the length of the slot 422, and a screw 424 is rotatably connected to the bottom of the clamping block 423. The axis of the screw 424 is parallel to the length of the slot 422, and the screw 424 is threaded into the mounting base 421. By rotating the screw 424, the clamping block 423 can be moved along the length of the slot 422 towards or away from the workpiece.
[0087] Reference Figure 8 The leveling component 41 includes a support plate 411, which is vertically mounted on the side wall of the worktable 11. A bottom cylinder is fixedly mounted on the side wall of the worktable 11 near the bottom. The bottom cylinder is vertically mounted, and the end of the piston rod of the bottom cylinder extends vertically upward and is fixedly connected to the side wall of the support plate 411. The extension and retraction of the piston rod of the bottom cylinder can drive the support plate 411 to slide vertically along the worktable 11.
[0088] Reference Figure 8A U-shaped horizontal sliding frame 412 is slidably connected to the top of the support plate 411. The inner walls of the parallel sides of the horizontal sliding frame 412 slide horizontally along the support plate 411. A double-rod double-acting cylinder 413 is horizontally fixed to the top of the support plate 411. The cylinder body of the double-rod double-acting cylinder 413 is fixed to the side wall of the support plate 411 near the top. One piston rod is fixed to the middle of the inner wall of the horizontal sliding frame 412, and the other piston rod passes through the support plate 411 and is connected to a sliding plate 414. The sliding plate 414 is horizontally arranged, and its two ends near the horizontal sliding frame 412 slide horizontally along the length of the horizontal sliding frame 412. To make the sliding process more stable, a long groove is horizontally provided on one side of the two parallel rods of the horizontal sliding frame 412 that are close to each other. The groove is not shown in the figure. The length direction of the groove is parallel to the length direction of the horizontal sliding frame 412. Correspondingly, sliding members that are adapted to the groove are fixed on both sides of the support plate 411 near the groove. The sliding members slide along the length direction of the groove, thereby making the sliding process of the horizontal sliding frame 412 along the support frame more stable. In addition, corresponding sliding members are also provided on both sides of the sliding plate 414 near the groove. The sliding members move in the groove along the length direction of the groove, which can make the movement process of the sliding plate 414 more stable.
[0089] Reference Figure 8 A push cylinder 415 is fixedly installed at the top center of the sliding plate 414. The push cylinder 415 is vertically positioned, and its piston rod extends vertically downwards. A leveling plate 416 is fixedly connected to the end of the piston rod. The leveling plate 416 is horizontally positioned and moves vertically following the piston rod of the push cylinder 415. Guide posts 417 are vertically slidably connected to the sliding plate 414 near both ends. The bottom of the guide posts 417 is fixedly connected to the top of the leveling plate 416. When the leveling plate 416 moves vertically, the guide posts 417 slide vertically along the sliding plate 414, thereby ensuring that the leveling plate 416 remains horizontal when it moves vertically under the push of the push cylinder 415.
[0090] The implementation principle of the dynamic ring production equipment and production process in Embodiment 1 of this application is as follows:
[0091] When performing preliminary cutting of the blank using machining center 1, firstly, the three-jaw chuck 3 is placed on the surface of the worktable 11, with the side of the three-jaw chuck 3 abutting against the positioning latch 514, and the side of the positioning rod 34 abutting against the fixing member 515, thus initially fixing the position of the three-jaw chuck 3. Then, the driving limit latch 521 is moved towards the positioning latch 514 until the positioning latch 514 and the limit latch 521 together hold the three-jaw chuck 3 tightly, while at the same time, the fixing member 515 and the limit member 523 together abut against the positioning rod 34.
[0092] According to the above technical solution, a cutting center position is pre-set on the worktable 11, and the position of the positioning clip 514 is fixed according to the cutting center position. This allows the operator to easily place the three-jaw chuck 3 on the worktable 11 when installing it, greatly reducing the workload and difficulty for the operator. Then, the positioning clip 514 and the limiting clip 521 together hold the three-jaw chuck 3 in place, and the fixing member 515 and the limiting member 523 press the positioning rod 34 against it, thus fixing the position of the center jaw 31, facilitating the subsequent cutting of the blank in half. Therefore, the above technical solution solves the problem of cumbersome clamping of the three-jaw chuck 3 and increased labor intensity mentioned in the background art, and has the technical effects of easy clamping and accurate positioning.
[0093] When cutting the blank using a cutter, the blank is cut into two semicircles by moving along the width of the worktable 11 with the cutting center as the zero point. The clearance groove 33 allows for clearance for the cutter's movement. By pre-positioning the three-jaw chuck 3 and the central jaw 31, preparatory work for blank cutting is done. Combined with the clearance groove 33 on the central jaw 31, the positioning and cutting of the cutter are facilitated. These mechanical changes simplify the production of the moving ring, reduce the blank cutting process, and improve work efficiency.
[0094] The cut semi-circular blank is placed on the positioning fixture 4, and the bottom of the blank is engaged in the engagement groove. First, the bottom cylinder drives the support plate 411 to slide vertically upward. Then, the piston rod of the double-acting cylinder 413 connected to the horizontal sliding frame 412 retracts, pushing the horizontal sliding frame 412 horizontally towards the blank. Then, the sliding plate 414 slides towards the blank until it is directly above the blank. By extending the piston rod of the pushing cylinder 415, the leveling plate 416 moves vertically downward, flattening the blank.
[0095] Then, the screw 424 is rotated, causing the clamping block 423 to move closer to the blank, clamping the blank onto the mounting base 421, which facilitates subsequent cutting of the cross-section and improves cutting accuracy. Furthermore, before cutting, the leveling component 41 is restored to its original state to avoid interference with the cutting of the blank.

[0099] The operator clamps the cylindrical blank onto the three-jaw chuck 3 body on the machining center 1. The cutting blade moves along the width of the worktable 11 with the cutting center as the zero point, cutting the blank into two semicircles.
[0100] S2, Milling the cross-section:
[0101] The cut semi-circular blanks are clamped on the positioning fixture 4, and the semi-circular blanks are milled flat using a cutting tool.
[0102] S3, Drill locating pin hole 05:

[0108] S6, assembled into a complete circle:
[0109] Insert the end of the positioning pin into the positioning pin hole 05 on the cross section, assemble the halved blanks into a complete circle, and then use the fixing bolt 08 to fix the two halved blanks.
[0110] S7, side cut and cut off:
[0111] The assembled round blank is mounted on a milling and turning machine 2. Its side is first cut, and then it is cut along the radial direction of the round blank to initially form the moving ring body 0.
[0112] S8, re-clamp and cut the cross-section:
[0113] The initially formed moving ring body 0 is then mounted again on the milling and turning machine 2, and the cutting surface in its S7 is cut to form the moving ring body 0.
[0114] 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.
