Description

Technical Field

[0001] This invention relates to the field of composite processing technology for brackets, specifically to a composite processing equipment for metal brackets of aviation obstruction lights. Background Technology

[0002] As a crucial load-bearing component of aviation warning equipment, the metal bracket of an aviation obstruction light directly impacts its installation stability and lifespan. Existing technologies integrate multiple metal processing steps such as grinding, cutting, and drilling into a single machine, such as integrated metal plate grinding and cutting equipment and specialized machining centers for automotive steering arm brackets. However, these existing composite processing machines are mostly designed for machining the planar or outer surfaces of specific workpiece types. For workpieces like aviation obstruction light metal brackets, which have internal bore structures and require simultaneous grinding of both the bore walls and the outer walls, a dedicated composite processing solution is still lacking.

[0003] The current processing of metal brackets for aviation obstruction lights presents the following technical problems: First, hole wall grinding and outer wall grinding typically need to be completed in steps on different equipment, or different grinding tools need to be changed. This results in fragmented processes, low efficiency, and repeated clamping can easily introduce positioning errors. Second, during the grinding process, there is interference between workpiece clamping and the grinding operation. When grinding the outer wall of the workpiece, the external clamping components will block part of the grinding area, making it impossible to achieve 360° grinding without blind spots, which seriously affects the grinding quality. Third, how to achieve mode switching of the grinding components and reliable workpiece fixation during the transition from hole grinding to outer wall grinding in existing grinding equipment is a long-standing technical challenge in the industry. Therefore, there is an urgent need for a composite processing equipment that can integrate hole wall grinding and outer wall grinding into the same device and achieve automatic repositioning of clamping components and reliable workpiece fixation during mode switching. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a composite processing equipment for metal brackets of aviation obstruction lights, which solves the problem that the grinding of the inner hole and the grinding of the outer wall of aviation obstruction light brackets currently require different equipment and cannot be coordinated.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a composite processing equipment for metal brackets of aviation obstruction lights, comprising a frame, a clamping component, a grinding component, a pressing and limiting component, and a control component.

[0006] The clamping component is mounted on the frame and is used to clamp the workpiece. The clamping component includes a movable frame, a first clamping plate, a second clamping plate, and a limiting screw. The movable frame is slidably mounted on the frame and can slide horizontally. The first clamping plate is fixedly connected to the movable frame, and the second clamping plate is slidably connected to the movable frame and can move vertically relative to the first clamping plate. The limiting screw is rotatably connected to the first clamping plate, with its axis extending vertically. An adjusting sleeve is fitted onto the limiting screw, and the adjusting sleeve is fixedly connected to the second clamping plate and threadedly engaged with the limiting screw. A driven gear is fixedly connected to the end of the limiting screw. When the limiting screw rotates, the threaded engagement drives the adjusting sleeve to move along the limiting screw, thereby causing the second clamping plate to move relative to the first clamping plate, thus clamping or releasing the workpiece.

[0007] The grinding component is mounted on the frame and includes a first floating plate, a second floating plate, and a drive screw. The first floating plate is located above the second floating plate, both being disc-shaped and coaxially arranged. The first floating plate is provided with a first locking element and a first threaded sleeve, while the second floating plate is provided with a second locking element and a second threaded sleeve. Both the first and second locking elements are electromagnetic rings, and the threaded sleeve is locked or disengaged from the drive screw by controlling the on / off state of the electromagnetic rings. The drive screw extends vertically and passes through the first and second threaded sleeves, and is connected to a reduction motor. When the electromagnetic ring is energized, the threaded sleeve is locked to the drive screw, and the floating plate rises and falls with the rotation of the drive screw; when the electromagnetic ring is de-energized, the threaded sleeve disengages from the drive screw, and the floating plate remains at its current position. By controlling the on / off state of the first and second locking elements, the first and second floating plates can be selectively raised and lowered synchronously under the drive of the drive screw, or the first floating plate can be locked at a certain height while the second floating plate continues to rise and fall.

[0008] A first grinding assembly is provided on the first floating plate, and a second grinding assembly is provided on the second floating plate. Multiple first grinding assemblies are provided and evenly distributed along the circumference of the first floating plate, and multiple second grinding assemblies are provided and evenly distributed along the circumference of the second floating plate, with the first and second grinding assemblies staggered in the circumferential direction. Each grinding assembly can be driven to rotate by a geared motor to grind the hole wall or outer wall. Each grinding assembly has a mating part at its upper end for connection with a downward pressure limiting component.

[0009] The downward limiting component is located above the grinding assembly and includes a movable plate, a conical platform, and a connecting member. The movable plate is horizontally mounted on the frame and connected to the lifting drive component, allowing it to move independently of the grinding assembly under the drive of the lifting drive component. The conical platform is rotatably connected below the movable plate and can rotate freely relative to the movable plate around a vertical axis. The conical platform is shaped like a frustum of a cone, wider at the top and narrower at the bottom, with rolling elements on its outer circumferential surface for rolling contact with the hole wall. Multiple circumferentially evenly distributed receiving holes are formed on the outer circumferential surface of the conical platform, each containing a ball bearing as a rolling element. The edges of the receiving holes have a constriction structure, with the ball bearing protruding from the outer surface of the conical platform and confined within the receiving hole by the constriction structure, preventing it from falling out. The ball bearing can roll freely within the receiving hole. When the conical platform enters the hole of the workpiece, the ball bearing rolls into contact with the hole wall, converting sliding friction into rolling friction and preventing scratching of the hole wall.

[0010] The connector is located at the bottom of the conical platform and is used for detachable connection with the upper end of the grinding assembly. In one embodiment, the connector is an electromagnet, and the upper end of the grinding assembly has a ferromagnetic mating portion. When the electromagnet is energized, it generates magnetic force to attract the mating portion, connecting the conical platform to the grinding assembly. When the power is off, the magnetic force disappears, disengaging the conical platform from the grinding assembly. In another embodiment, the connector is a snap-fit ​​structure, including multiple circumferentially distributed elastic claws. The upper end of the grinding assembly has an annular groove adapted to the snap-fit, and the detachable connection between the conical platform and the grinding assembly is achieved by the engagement and disengagement of the claws and the groove.

[0011] The control component is electrically connected to the clamping component and the grinding component, and is used to control the on / off state of the first locking component and the second locking component, so that the first floating plate and the second floating plate move synchronously up and down or move separately under the drive screw. The second grinding component has an outward movement stroke. When the second grinding component moves outward, the clamping component is driven to release and move away from the workpiece through the linkage structure of the rack, driven gear and drive plate.

[0012] Furthermore, each of the grinding components is provided with a rack, which extends horizontally and meshes with the driven gear. A drive plate is fixedly connected to the outer end of the rack. When the second grinding component moves radially outward, the rack moves outward accordingly, driving the driven gear to rotate. The driven gear drives the limiting screw to rotate, and the limiting screw drives the adjusting sleeve to move through a threaded engagement. This causes the second clamping plate to move relative to the first clamping plate to release the workpiece. At the same time, the drive plate pushes against the moving frame, causing the moving frame to slide away from the workpiece, and the entire clamping component moves away from the workpiece.

[0013] Furthermore, the device also includes a limiting ball, which is mounted on the frame and located above or below the workpiece. The limiting ball is installed on the frame via an elastic element and can elastically extend and retract in the vertical direction. When the conical platform enters the hole of the workpiece, the outer circumferential surface of the conical platform pushes the limiting ball outward, causing the limiting ball to press against the end face of the workpiece or the edge of the hole, thus cooperating with the conical platform to fix the workpiece in both directions.

[0014] Furthermore, the device also includes a hydraulic rod disposed on the second floating plate and electrically connected to the control component, used to radially push the second grinding assembly outward after the second floating plate descends to the point where the second grinding assembly leaves the hole of the workpiece.

[0015] Furthermore, the geared motor is connected to the first floating plate via a connecting rod. An electromagnet is mounted on the connecting rod. When the electromagnet is energized, the connecting rod engages with the first floating plate, and the geared motor drives the first floating plate to rotate via the connecting rod. When the electromagnet is de-energized, the connecting rod disengages from the first floating plate. In the outer wall grinding mode, the electromagnet is energized, and the geared motor drives the first floating plate and the workpiece to rotate slowly, allowing the outer wall grinding to cover the entire circumference.

[0016] This invention provides a composite processing device for metal brackets of aviation obstruction lights. It has the following beneficial effects:

[0017] 1. This invention incorporates a conical platform in the pressure limiting component and embeds freely rolling balls as rolling elements on the outer circumferential surface of the conical platform. Simultaneously, a narrowing structure at the edge of the receiving hole confines the balls within the receiving hole, preventing them from falling out. This design ensures that when the conical platform enters the workpiece hole, rolling friction, rather than sliding friction, occurs between the balls and the hole wall. This reduces the frictional resistance between the conical platform and the hole wall, preventing scratches and wear on the hole wall and effectively protecting the surface quality of the hole wall. It is particularly suitable for machining workpieces requiring high hole wall smoothness, such as metal brackets for aviation obstruction lights.

[0018] 2. This invention achieves a detachable connection between the conical platform and the grinding assembly by setting a connector at the bottom of the conical platform and a mating part at the upper end of the grinding assembly. When the equipment is in the in-hole grinding mode, the conical platform remains outside the hole and does not enter the hole, thereby avoiding motion interference between the conical platform and the grinding assembly and additional friction on the hole wall; when the equipment switches to the outer wall grinding mode, the conical platform quickly engages with the grinding assembly extending outside the hole through the connector and enters the hole, providing radial support as needed.

[0019] 3. This invention uses a first floating plate and a second floating plate, arranged vertically, to form the grinding components. Each floating plate has an independent locking mechanism, enabling the first and second floating plates to move synchronously or independently under the drive of a lead screw. During internal grinding, both floating plates descend synchronously, allowing all grinding components to simultaneously enter the hole and grind the hole wall, resulting in high grinding efficiency. When switching to external wall grinding, the first floating plate locks itself inside the hole to maintain the workpiece's position, while the second floating plate continues to descend, extending the second grinding component outside the hole and switching to external wall grinding. The entire switching process requires no tool changes or workpiece re-clamping, effectively avoiding the accumulation of positioning errors caused by multiple clamping operations and significantly improving processing efficiency and accuracy.

[0020] 4. This invention utilizes a linked structure design of a rack, driven gear, limiting screw, and drive plate. When the second grinding assembly moves radially outward, the rack moves accordingly, driving the driven gear to rotate. The driven gear then drives the limiting screw to rotate. The limiting screw, through threaded engagement, drives the second clamping plate to move, releasing the workpiece. Simultaneously, the drive plate pushes against the moving frame, moving the entire clamping component away from the workpiece, thus providing ample operating space for outer wall grinding. This achieves workpiece fixation, ensuring that the workpiece does not shift or vibrate during outer wall grinding, further guaranteeing processing quality and operational safety.

[0021] In summary, this invention effectively solves the technical problems in existing aviation obstruction light metal bracket processing equipment, such as the dispersed grinding processes of the inner and outer walls, clamping interference, difficulty in mode switching, and easy damage to the inner and outer walls, through the conical rolling body structure, detachable connection mechanism, independent control of double-layer floating plates, and the synergistic effect of linkage clamping clearance and bidirectional fixing structure. It realizes efficient and high-quality switching processing of inner and outer wall grinding on the same equipment. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] This embodiment provides a basic implementation plan for a composite processing equipment for metal brackets of aviation obstruction lights.

[0035] Please see the appendix Figure 1 - Figure 6 The device includes a frame 1, a clamping component 2, a grinding component 3, a pressing and limiting component 4, and a control component. The frame 1 serves as the mounting base for all components of the invention and adopts a metal frame structure. The clamping component 2 is mounted on the frame 1 and is used to clamp the workpiece 100. In this embodiment, the clamping component 2 is a conventional jaw structure (not shown in the figure), including two opposing jaws. Clamping and releasing are achieved by driving a cylinder or a reduction motor 34. The clamping component 2 is electrically connected to the control component and performs clamping or releasing actions according to the instructions of the control component.

[0036] The grinding component 3 is mounted on the frame 1 and includes a first floating plate 31, a second floating plate 32, and a drive screw 33. The first floating plate 31 is located above the second floating plate 32, and both are disc-shaped and coaxially arranged. The first floating plate 31 is provided with a first locking member 311 and a first threaded sleeve 312, and the second floating plate 32 is provided with a second locking member 321 and a second threaded sleeve 322. In this embodiment, both the first locking member 311 and the second locking member 321 are electromagnetic rings, and the locking engagement or disengagement of the threaded sleeve and the drive screw 33 is achieved by controlling the on / off state of the electromagnetic rings. The drive screw 33 extends vertically and passes through the first threaded sleeve 312 and the second threaded sleeve 322, with its bottom end connected to the reduction motor 34. The first floating plate 31 is provided with a first grinding assembly 35, and the second floating plate 32 is provided with a second grinding assembly 36.

[0037] The first grinding assembly 35 and the second grinding assembly 36 have basically the same structure. The first grinding assembly 35 includes a rotating shaft 352. A telescopic rod 353 is fixedly connected to the outer end of the rotating shaft 352. The telescopic rod 353 includes a hollow rod and a movable rod slidably connected inside the hollow rod. An electromagnetic element and a strong spring are fixedly connected between the movable rod and the hollow rod. Initially, the telescopic rod 353 is kept in a retracted state by the electromagnetic element. When it enters the hole of the workpiece 100, the electromagnetic element is disconnected, so that the telescopic rod 353 extends outward as much as possible. An arc plate 354 is fixedly connected to the end of the telescopic rod 353. A grinding disc 356, i.e., sandpaper, is provided on the outer wall of the arc plate 354. A grinding motor 355 is fixedly connected to the bottom of the rotating shaft 352. The grinding motor 355 drives multiple grinding discs 356 to rotate rapidly to achieve grinding of the hole wall.

[0038] The downward limiting component 4 is located above the grinding assembly and includes a movable plate 41, a conical platform 42, and a connecting component. The movable plate 41 is horizontally mounted on the frame 1 and connected to the lifting drive component, allowing it to move independently of the grinding assembly 3 under the drive of the lifting drive component. The conical platform 42 is rotatably connected to the lower part of the movable plate 41 and can rotate freely relative to the movable plate 41 around a vertical axis. The conical platform 42 is a frustum-shaped cone with a larger top and a smaller bottom. Multiple circumferentially distributed receiving holes are provided on its outer circumferential surface. Each receiving hole contains a ball bearing as a rolling element (not shown in the figure). The edges of the receiving holes are provided with a constriction structure. The ball bearing protrudes from the outer surface of the conical platform 42 and is confined within the receiving hole by the constriction structure, preventing it from falling out. The ball bearing can roll freely within the receiving hole for rolling contact with the hole wall. The connector is located at the bottom of the conical platform 42. In this embodiment, the connector is an electromagnet 342. The upper end of the grinding assembly (that is, the top of the rotating shaft 352) is provided with a ferromagnetic mating part. When the electromagnet 342 is energized, it generates a magnetic force to attract the mating part, connecting the conical platform 42 with the grinding assembly. When the power is off, the magnetic force disappears, causing the conical platform 42 to detach from the grinding assembly.

[0039] The control component is a PLC controller, which is electrically connected to the clamping component 2, the grinding component 3 and the pressing limit component 4. It is used to control the on and off of the first locking component 311 and the second locking component 321 so that the first floating plate 31 and the second floating plate 32 move synchronously or move separately under the drive of the drive screw 33. At the same time, it controls the lifting and lowering of the moving plate 41 of the pressing limit component 4 and the on and off of the electromagnet 342.

[0040] The working process of this embodiment is as follows: In the hole grinding mode, the control unit controls the first locking member 311 and the second locking member 321 to be energized simultaneously, so that the first threaded sleeve 312 and the second threaded sleeve 322 are locked together with the drive screw 33. The reduction motor 34 drives the drive screw 33 to rotate in the forward direction, and the first floating plate 31 and the second floating plate 32 descend synchronously. The first grinding assembly 35 and the second grinding assembly 36 enter the hole of the workpiece 100 synchronously to grind the hole wall. During this process, the downward limiting member 4 remains in a standby state above the hole and does not enter the hole. When switching to the outer wall grinding mode, the control unit controls the first locking member 311 to be de-energized, the first floating plate 31 is locked at the first height, the second locking member 321 remains energized, and the second floating plate 32 continues to descend until the second grinding assembly 36 completely leaves the hole of the workpiece 100. Subsequently, the geared motor 34 reverses to drive the second grinding assembly 36 to move upward to its highest position. The electromagnet 342 is energized to connect the conical platform 42 with the second grinding assembly 36. The moving plate 41 moves downward to allow the conical platform 42 to enter the hole, and the balls on the outer circumference of the conical platform 42 roll into contact with the hole wall. Then, the second grinding assembly 36 moves outward to the outer wall position for grinding. After grinding is completed, all components are reset.

[0041] Example 2

[0042] The difference between this embodiment and Embodiment 1 lies in the specific structure of the connector at the bottom of the conical truss 42. In this embodiment, the connector is a snap-fit ​​structure, rather than an electromagnet 342.

[0043] The latching structure includes multiple elastic claws distributed circumferentially at the bottom of the conical platform 42. Each claw is a flexible metal sheet with an inwardly protruding engaging portion at its end. The upper end of the grinding assembly has a mating portion adapted to the latch, which is an annular groove structure. When the grinding assembly moves to its highest position, the mating portion inserts into the central hole of the latch. During insertion, the claws are stretched open by the mating portion and undergo elastic deformation. When the mating portion reaches a predetermined position, the claws reset under the action of elastic force, and the engaging portion engages into the groove, achieving a locking connection between the conical platform 42 and the grinding assembly. When disengagement is required, the control unit drives a disengagement mechanism to push the claws outward, causing the engaging portion to disengage from the groove, and the grinding assembly can then separate from the conical platform 42.

[0044] Compared to the electromagnet 342 connection method in Embodiment 1, the snap-fit ​​connection method in this embodiment does not require continuous power to maintain the connection, saving energy and avoiding the overheating problem of the electromagnet 342. The connection is more reliable and will not accidentally disengage due to vibration or power failure during grinding, making it suitable for processing scenarios with higher safety requirements. The other structures and working processes of this embodiment are the same as in Embodiment 1, and will not be repeated here.

[0045] Example 3

[0046] Based on Embodiment 1 or Embodiment 2, this embodiment further adds a specific linkage structure for the clamping component 2, a limiting ball, and an auxiliary structure such as the hydraulic rod 6, forming a more complete and automated composite processing equipment.

[0047] Please see the appendix Figure 7 - Figure 9 In this embodiment, the clamping component 2 includes a movable frame 21, a first clamping plate 22, a second clamping plate 23, and a limiting screw 24. The movable frame 21 is slidably mounted on the frame 1 and can slide horizontally. The first clamping plate 22 is fixedly connected to the movable frame 21, and the second clamping plate 23 is slidably connected to the movable frame 21 and can move vertically relative to the first clamping plate 22. The limiting screw 24 is rotatably connected to the first clamping plate 22, and its axis extends vertically. An adjusting sleeve 25 is sleeved on the limiting screw 24, and the adjusting sleeve 25 is fixedly connected to the second clamping plate 23 and threadedly engaged with the limiting screw 24. A driven gear 26 is fixedly connected to the lower end of the limiting screw 24. When the limiting screw 24 rotates, the adjusting sleeve 25 is driven to move along the limiting screw 24 through the threaded engagement, thereby driving the second clamping plate 23 to move relative to the first clamping plate 22, thus clamping or releasing the workpiece 100.

[0048] A rack 37 is fixedly connected to the side wall of the grinding assembly. The rack 37 extends horizontally and meshes with the driven gear 26. A drive plate 38 is fixedly connected to the outer end of the rack 37. The moving direction of the drive plate 38 is the same as the extending direction of the rack 37. When the second grinding assembly 36 moves radially outward, the rack 37 moves outward accordingly, driving the driven gear 26 to rotate. The driven gear 26 drives the limiting screw 24 to rotate. The limiting screw 24 drives the adjusting sleeve 25 to move through the threaded engagement, causing the second clamping plate 23 to move relative to the first clamping plate 22 to release the workpiece 100. At the same time, the drive plate 38 moves outward and pushes against the moving frame 21, causing the moving frame 21 to slide away from the workpiece 100. The entire clamping component 2 moves away from the workpiece 100, making room for the outer wall grinding. When the second grinding component 36 retracts, the rack 37 moves in the opposite direction, driving the driven gear 26 to reverse, and the limit screw 24 reverses to drive the second clamping plate 23 to reset. The drive plate 38 disengages from the moving frame 21. Note that at this time, a new workpiece 100 needs to be placed on the device. First, push the clamping component 2 to move, so that the first clamping plate 22 and the second clamping plate 23 are close to the new workpiece 100, and then push the rack 37 back to complete the purpose of automatic clamping.

[0049] The second polishing assembly 36 also includes a guide slider 39, and a guide groove is provided on the second floating plate 32. The guide slider and the guide groove are slidably connected.

[0050] This embodiment also includes a hydraulic rod 6. When the second floating plate 32 descends to the point where the second grinding assembly 36 leaves the hole of the workpiece 100, the control component controls the hydraulic rod 6 to start, pushing the second grinding assembly 36 to move radially outward to perform outer wall grinding.

[0051] This embodiment also includes a limiting ball bearing, which is mounted on the frame 1 above or below the workpiece 100. It is installed on the frame 1 via an elastic element and can elastically extend and retract in the vertical direction. When the conical stage 42 enters the hole of the workpiece 100, the outer circumferential surface of the conical stage 42 pushes the limiting ball bearing outward, causing it to press against the end face or edge of the hole of the workpiece 100. At this time, the conical stage 42 provides radial support and automatic centering from the inside, while the limiting ball bearing provides axial clamping force from the outside. The two work together to achieve bidirectional fixation of the workpiece 100, ensuring that the workpiece 100 does not shift or vibrate during grinding.

[0052] In this embodiment, the geared motor 34 is also connected to the first floating plate 31 via a connecting rod 341. An electromagnet 342 is mounted on the connecting rod 341, which is a retractable annular plate. The annular plate includes a first annular plate with multiple limiting grooves. Multiple limiting posts are slidably connected within the limiting grooves, and the tops of the multiple limiting posts are connected to a second annular plate. When the electromagnet 342 is energized, the connecting rod 341 engages with the first floating plate 31, and the geared motor 34 drives the first floating plate 31 to rotate via the connecting rod 341. When the electromagnet 342 is de-energized, the connecting rod 341 disengages from the first floating plate 31. In the outer wall grinding mode, the control unit energizes the electromagnet 342, causing the connecting rod 341 to engage with the first floating plate 31. The geared motor 34 drives the first floating plate 31 to rotate slowly via the connecting rod 341. The first floating plate 31, through the contact between the conical platform 42 and the hole wall, drives the workpiece 100 to rotate synchronously and slowly, thereby ensuring that the outer wall grinding covers the entire circumferential surface.

[0053] The complete workflow of this embodiment is as follows.

[0054] In the initial state, the clamping component 2 clamps the workpiece 100, the pressing and limiting component 4 is located above the outside of the hole, the connecting component is in the disengaged state, and the first locking component 311 and the second locking component 321 are both de-energized.

[0055] After the grinding inside the hole begins, the control unit simultaneously energizes the first locking element 311 and the second locking element 321. The reduction motor 34 drives the drive screw 33 to rotate in the forward direction, and the first floating plate 31 and the second floating plate 32 descend synchronously. The first grinding assembly 35 and the second grinding assembly 36 enter the hole of the workpiece 100, and each grinding assembly starts to rotate and grind the hole wall. During this process, the downward limiting component 4 remains outside the hole and is ready, and the conical platform 42 does not enter the hole and does not contact the hole wall.

[0056] After the hole wall is polished, the control unit de-energizes the first locking member 311, locks the first floating plate 31 at the first height, and keeps the first polishing assembly 35 inside the hole. At the same time, the control unit keeps the second locking member 321 energized, and the second floating plate 32 continues to descend until the second polishing assembly 36 completely leaves the hole of the workpiece 100. Then, the reduction motor 34 reverses, driving the second polishing assembly 36 to move upward to the highest position. The control unit controls the connecting member to connect the conical platform 42 with the second polishing assembly 36. Then, the control unit controls the moving plate 41 to move downward so that the conical platform 42 enters the hole of the workpiece 100. The balls on the outer circumference of the conical platform 42 roll and contact the hole wall. The limiting balls are pushed by the conical platform 42 and press against the end face or edge of the hole of the workpiece 100, cooperating with the conical platform 42 to achieve bidirectional fixation of the workpiece 100.

[0057] After the conical stage 42 is in place, the control unit activates the hydraulic rod 6, pushing the second grinding assembly 36 radially outward to the outer wall of the workpiece 100. During the outward movement of the second grinding assembly 36, the rack 37 drives the driven gear 26 to rotate, and the limiting screw 24 rotates to drive the second clamping plate 23 to move to release the workpiece 100. At the same time, the drive plate 38 pushes against the moving frame 21 to move the clamping component 2 away from the workpiece 100.

[0058] Subsequently, the control unit controls the geared motor 34 to drive the drive screw 33 in reverse, which in turn drives the second grinding assembly 36 to grind the outer wall of the workpiece 100. Simultaneously, the control unit energizes the electromagnet 342, causing the connecting rod 341 to engage with the first floating plate 31. The geared motor 34, through the connecting rod 341, drives the first floating plate 31 and the workpiece 100 to rotate slowly, achieving full-circumference grinding. After the outer wall grinding is completed, the control unit stops the geared motor 34, de-energizes the electromagnet 342, opens the hydraulic rod 6, and causes the rack 37 to move in reverse, driving the driven gear 26 to reverse and reset the clamping assembly 2. The connecting piece disengages, and the moving plate 41 moves upward, causing the conical platform 42 to exit the hole. Finally, the first locking member 311 and the second locking member 321 are re-energized, causing the drive screw 33 to rotate forward, raising and resetting the first floating plate 31 and the second floating plate 32. The clamping assembly 2 then re-clamps the workpiece 100, completing the entire processing process.
