[0007] Preferably, a clamping arm is provided on the Y-axis motion stage, and the clamping arm is located at one of the two ends of the Y-axis motion stage extending in the length direction of the main unit. The clamping arm has a recessed hole, and the opening of the recessed hole faces away from the Y-axis motion stage. The tray is rotatably connected to a control arm, and the control arm rotates into the recessed hole to abut against the clamping arm.

[0017] like Figures 1 to 4 As shown, an automatic oscillation stress relief device 100 includes a main unit 10 placed on a plane; And, the lead screw motion mechanism 20 mounted on the main unit 10, And, an intermediate motion table 30 fixedly connected to the lead screw motion mechanism 20, the intermediate motion table 30 being slidably connected to the main machine 10, the lead screw motion mechanism 20 driving the intermediate motion table 30 to slide along the length extension direction of the main machine 10; And, a support structure 40 slidably connected to the intermediate motion stage 30, the support structure 40 being located on the side of the intermediate motion stage 30 away from the main stage 10, the support structure 40 being perpendicular to the length extension direction of the main stage 10 along the sliding direction of the intermediate motion stage 30 on the horizontal plane. And, a first thrust device 50 is fixedly installed on the main unit 10. The first thrust device 50 is fixedly connected to the bearing structure 40. The first thrust device 50 pushes the bearing structure 40 and the intermediate motion table 30 to slide back and forth along the length extension direction of the main unit 10. And a second thrust device 60 fixedly installed on the main unit 10, the second thrust device 60 being fixedly connected to the bearing structure 40, the second thrust device 60 pushing the bearing structure 40 to slide back and forth relative to the intermediate motion platform 30.
[0018] In this way, graphite boats and other products are placed on the support structure 40. The first thrust device 50 is activated, pushing the intermediate motion platform 30 and the support structure 40 to reciprocate along the length of the main platform 10. Then, the second thrust device 60 is activated, driving the support structure 40 to reciprocate relative to the intermediate motion platform 30 along the width of the main platform 10. After a certain number of repetitions, the motion stops, and the screw motor moves the intermediate platform and the support structure 40 out of the working area for the next testing process. By driving the product to automatically perform regular repetitive movements in the X and Y directions, the stress of graphite boats and other products is effectively removed, achieving high efficiency, saving manpower, and controllable stress removal speed.
[0019] The first thrust device 50 and the second thrust device 60 can precisely control the product to oscillate regularly in the mutually perpendicular X and Y axes. This controllable, multi-directional mechanical action can more evenly and thoroughly eliminate anisotropic residual stress inside the product, avoiding the problems of uneven force and incomplete coverage that may occur with manual hammering, resulting in good consistency of treatment effect and more stable product quality.
[0020] During implementation, the main unit 10 should be placed stably on a level, solid ground or work platform to ensure stability and prevent wobbling. The main unit 10 can be a rectangular or square metal frame structure with guide rails machined on its top. Inside the guide rails of the main unit 10, along its length (X-axis direction), a lead screw motion mechanism 20 is installed, consisting of a servo motor, a precision lead screw, a nut seat, and a linear guide pair. The servo motor is connected to the lead screw via a coupling, the nut seat engages with the lead screw, and is fixedly connected to the bottom plane of the intermediate motion stage 30. This allows the lead screw motion mechanism 20 to precisely control the position of the intermediate motion stage 30 in the X-axis direction.
[0021] The intermediate motion table 30 is a rectangular plate, and its bottom is slidably connected to the linear guide rail pair on the main unit 10 through a slider, so that it can slide along the length direction (X-axis direction) of the main unit 10; The support structure 40 is designed as a detachable tray 42 or clamping platform for placing the graphite boat to be processed. The bottom of the support structure 40 is slidably connected to the top surface of the intermediate motion stage 30 via another set of linear guide rails. The extension direction of this set of guide rails is perpendicular to the length direction (X-axis direction) of the main stage 10 in the horizontal plane, that is, along the width direction (Y-axis direction) of the main stage 10.
[0022] On the main unit 10, near the initial position of the intermediate motion stage 30, a first thrust device 50 is fixedly installed. This first thrust device 50 can be a pneumatic cylinder, a hydraulic cylinder, or an electric piston rod. Its cylinder body is fixed to the main unit 10, while the end of its piston rod is fixedly connected to the supporting structure 40. When the first thrust device 50 is activated, its thrust acts directly on the supporting structure 40, and through the sliding connection between the supporting structure 40 and the intermediate motion stage 30, pushes the entire intermediate motion stage 30, along with the supporting structure 40, to perform high-frequency, short-stroke reciprocating sliding along the length direction (X-axis) of the main unit 10, generating X-axis oscillations.
[0023] On the main unit 10, a second thrust device 60 is fixedly installed at a 90-degree angle to the first thrust device 50 (i.e., along the width direction of the main unit 10, the Y-axis). This second thrust device 60 can also be a pneumatic cylinder, hydraulic cylinder, or electric piston rod. Its cylinder body is fixed to the main unit 10, and the end of the piston rod is also fixedly connected to the bearing structure 40, but the connection point must ensure that the thrust direction is consistent with the sliding direction of the bearing structure 40 relative to the intermediate moving platform 30. When the second thrust device 60 is activated, its thrust acts directly on the bearing structure 40, pushing the bearing structure 40 to overcome the friction between it and the intermediate moving platform 30, causing it to reciprocate along the guide rail (i.e., the Y-axis direction) on the top surface of the intermediate moving platform 30 at a high frequency with short strokes, generating Y-axis oscillations.
[0024] The device is also equipped with a programmable logic controller (PLC) or an industrial computer. In the control interface, the operator can preset parameters such as oscillation mode (e.g., first X-axis and then Y-axis, or X / Y alternation), single oscillation stroke, oscillation frequency, total oscillation time, or number of oscillation cycles.
[0025] For further details, please refer to Figure 2 The first thrust device 50 includes a support frame 51 fixedly connected to the main unit 10; And, a first cylinder 52 fixedly mounted on the support frame 51; And a first support plate 53 fixedly connected to the piston rod of the first cylinder 52; And, a first spring 54 fixedly connected at one end to the first support plate 53, the number of first springs 54 is at least two, and the two first springs 54 are distributed in a mirror image along the central axis of the first support plate 53. And a second support plate 55 is fixedly connected to the end of the first spring 54 away from the first support plate 53, and the side of the second support plate 55 away from the first spring 54 is fixedly connected to the bearing structure 40.
[0026] During implementation, an L-shaped metal support frame 51 is fixedly installed at one end of the main unit 10 along its length (X-axis). The support frame 51 is securely locked to the main unit 10 with bolts to ensure that it has sufficient rigidity and stability to withstand subsequent reciprocating forces; At the top of the support frame 51, a first cylinder 52 is fixed with bolts. The first cylinder 52 is a double-acting cylinder. Its rear end is fixed to the support frame 51, and the cylinder axis is parallel to the length direction (X-axis) of the main unit 10. The cylinder's air inlet and exhaust port are connected to the air source through solenoid valves, and the opening and closing of the solenoid valves are controlled by a PLC. The piston rod end of the first cylinder 52 is fixedly connected to the center of a rectangular first support plate 53. The first support plate 53 is usually made of steel plate and serves as a force transmission and spring mounting base. On the side of the first support plate 53 opposite to the cylinder, at least two first springs 54 (high fatigue-resistant cylindrical helical compression springs) are installed with their central axis as the axis of symmetry. The parameters (wire diameter, mean diameter, free length, stiffness coefficient) of the two first springs 54 are exactly the same to ensure symmetrical force distribution.
[0027] The other ends of the two first springs 54 are respectively fitted onto and fixed to another second support plate 55. The second support plate 55 is parallel to the first support plate 53, and its side facing away from the springs is rigidly fixed to the load-bearing structure 40 by bolts, clamps, or welding. In this way, the first support plate 53, the first springs 54, and the second support plate 55 are connected in series, and finally the force is transmitted to the load-bearing structure 40.
[0028] In this way, during the reciprocating motion, due to the periodic start-stop and reversal of the first cylinder 52, and the inherent inertia of the system itself (including the supporting structure 40, the intermediate motion table 30, and the workpiece on it), the system will experience momentary impact or vibration when the piston rod of the first cylinder 52 reaches its reversal point, or when external disturbances occur (such as the instantaneous release of internal stress in the workpiece causing micro-vibrations). At this time, the first spring 54, connected in series between the first support plate 53 and the second support plate 55, plays a crucial role in buffering and energy conversion. It allows for a small relative elastic displacement in the axial direction between the first support plate 53 (directly driven by the cylinder) and the second support plate 55 (connected to the supporting structure 40), converting part of the rigid impact kinetic energy into the elastic potential energy of the spring. Subsequently, the release of this potential energy causes the system to generate attenuated high-frequency micro-vibrations, effectively amplifying the high-frequency oscillation effect.
[0029] For further details, please refer to Figure 1 and Figure 3 As shown, the supporting structure 40 includes a Y-axis motion stage 41 that is slidably connected to the intermediate motion stage 30; And a support plate 42 that is detachably connected to the Y-axis motion table 41, the support plate 42 being located on the side of the Y-axis motion table 41 away from the intermediate motion table 30.
[0030] In implementation, the Y-axis motion table 41 is a rectangular rigid plate (e.g., made of aluminum alloy or steel plate), and its lower surface is slidably connected to the upper surface of the intermediate motion table 30 via a set of linear guide rails. The sliding direction of this set of guide rails is perpendicular to the length direction (X-axis) of the main stage 10, that is, along the width direction (Y-axis) of the main stage 10, so that the Y-axis motion table 41 can perform precise linear reciprocating sliding along the Y-axis on the top surface of the intermediate motion table 30. The side of the Y-axis motion table 41 is fixedly connected to the drive end of the second thrust device 60 to receive the Y-axis driving force. The support plate 42 is a component that directly supports and fixes workpieces such as graphite boats. Its size and structure can be designed according to the shape of the specific workpiece and the clamping requirements, for example, it can be a flat plate with positioning grooves, vacuum suction cups, adjustable claws or standard interfaces. The support plate 42 is located above the Y-axis motion table 41 (i.e., on the side away from the intermediate motion table 30). To enable quick replacement, a detachable connection mechanism is designed between the Y-axis motion table 41 and the tray 42.
[0031] In this way, the supporting structure 40 is modularized into a fixed Y-axis motion table 41 and a replaceable special pallet 42. When the production line needs to switch to graphite boat products of different specifications and shapes, only the corresponding pallet 42 needs to be replaced, without replacing or adjusting the entire supporting structure 40 and its underlying precision sliding components (linear guide pairs). This greatly reduces the downtime required for product changeovers, improves the equipment's adaptability to different products, and enables a single processing line to efficiently process multiple types of workpieces, meeting the needs of small-batch, multi-variety production.
[0032] For further details, please refer to Figure 3 As shown, a clamping arm 43 is provided on the Y-axis motion table 41. The clamping arm 43 is located at one of the two ends of the Y-axis motion table 41 in the length extension direction of the main unit 10. A recessed hole 431 is provided on the clamping arm 43, and the opening of the recessed hole 431 faces away from the Y-axis motion table 41. The pallet 42 is rotatably connected to a control arm 44, which rotates into the recess 431 and abuts against the clamping arm 43.
[0033] In implementation, a U-shaped clamping arm 43 is fixedly installed on one end (such as the front or rear end) of the Y-axis motion table 41, extending along the length of the main unit 10 (i.e., the X-axis direction). The clamping arm 43 has a recessed hole 431 on its side. The opening direction of the recessed hole 431 is designed to be away from the main body of the Y-axis motion table 41, typically horizontal, to facilitate the insertion and removal of the control arm 44. The inner wall of the recessed hole 431 can be a U-shaped groove or a square groove, designed to receive and lock the corresponding part of the control arm 44. The clamping arm 43 and the recessed hole 431 have sufficient structural strength to withstand the shear force and bending moment generated during oscillation.
[0034] At the corresponding end of each dedicated pallet 42 that mates with the Y-axis motion table 41 (corresponding to the position of the clamping arm 43), a control arm 44 is rotatably connected via a pivot. The control arm 44 can swing within a certain angle range in a vertical or near-vertical plane about its pivot. The shape of the free end of the control arm 44 matches the recess 431 on the clamping arm 43, for example, it can be a cylindrical or rectangular structure.
[0035] In this way, by rotating the control arm 44 into the recess 431 to form a supporting mechanical structure, an intuitive and quick connection and separation method is provided. Operation requires no complex tools; typically, a single handle or simple lever action is sufficient to lock or release, significantly reducing changeover time. Its mechanical, rigid supporting locking method, compared to pure friction or magnetic connections, offers higher connection rigidity and impact resistance when subjected to high-frequency, multi-directional oscillation forces, significantly improving reliability and effectively preventing the risk of the tray 42 loosening or shifting under severe vibration.
[0036] For further details, please refer to Figure 3 As shown, the second thrust device 60 includes a second cylinder 61 fixedly mounted on the main unit 10, and the second cylinder 61 is located on one of the two sides in the width direction of the Y-axis motion table 41. And a third support plate 62 fixedly connected to the piston rod of the second cylinder 61, the side of the third support plate 62 away from the second cylinder 61 facing the side of the Y-axis motion table 41 in the width direction. In addition, a second spring 63 is fixed at one end to the intermediate motion table 30, and the other end of the second spring 63 is fixed to the Y-axis motion table 41. The axis of the second spring 63 extends in the same direction as the width of the Y-axis motion table 41.
[0037] In practice, when it is necessary to drive the Y-axis motion table 41, its pallet 42, and the workpiece to move in the Y direction, the PLC controls the solenoid valve to extend the piston rod of the second cylinder 61. The piston rod, through the third support plate 62, pushes the Y-axis motion table 41, overcoming the resistance of the second spring 63, causing the entire supporting structure 40 to move along the Y-axis (away from the cylinder). This process is an active propulsion stroke, powered by the cylinder.
[0038] When the Y-axis motion stage 41 is pushed to one side and reaches the predetermined end of its stroke, the PLC controls the solenoid valve to switch, causing the piston rod of the second cylinder 61 to lose thrust and begin to retract (or remain in the extended position, but with exhaust pressure released). At this time, the elastic potential energy stored in the compressed second spring 63 is released, and its restoring force acts on the Y-axis motion stage 41, driving the Y-axis motion stage 41 to move in the opposite direction and return to its initial intermediate position. This process is the spring reset stroke.
[0039] The second cylinder 61, controlled by a PLC, repeatedly cycles through "extend-retract (pressure relief)" at a certain frequency (e.g., 1-10Hz). During the extension phase, the cylinder propels the system to accelerate; during the retraction / pressure relief phase, the cylinder force is removed, and the system decelerates, stops, and accelerates in the opposite direction under the restoring force of the second spring 63. Since the device (Y-axis motion table 41, support plate 42, and workpiece) has mass, and the second spring 63 has elasticity and damping, this periodic switching between "push-driven" and "spring-returning" excites a damped oscillation system in the Y-axis direction. By adjusting the operating frequency, stroke, and stiffness of the second cylinder 61, the natural frequency and amplitude of this oscillation system can be adjusted, thereby generating effective mechanical oscillations in the Y-axis to relieve workpiece stress.
[0040] For further details, please refer to Figure 4 As shown, a rotary shaft 411 is fixedly connected to the Y-axis motion table 41. The rotary shaft 411 is located in the middle position of the Y-axis motion table 41, and the support plate 42 is rotatably connected to the rotary shaft 411.
[0041] In implementation, a rotary shaft 411 is fixed vertically upward (i.e., away from the intermediate motion table 30) at the geometric center of the Y-axis motion table 41 or at a midpoint near the center of gravity. This rotary shaft 411 is typically a high-strength alloy steel spindle, its lower end securely connected to the top surface of the Y-axis motion table 41 via a flange, lock nut, or welding, ensuring that the axis is perpendicular to the plane of the Y-axis motion table 41. The upper end of the rotary shaft 411 is machined with a precision cylindrical surface as a rotation reference.
[0042] By allowing the pallet 42 to rotate relative to the Y-axis motion table 41, workpieces such as graphite boats supported on the pallet 42 can be precisely rotated to any preset angle according to the needs of subsequent processes (such as visual inspection, automatic loading and unloading, and multi-faceted processing). This breaks the limitation of fixed workpiece orientation in traditional oscillation devices, enabling this device to be easily integrated into automated production lines that require workpiece repositioning. It achieves seamless and flexible connection between stress-relief stations and subsequent stations, significantly expanding the application scenarios of the equipment.
[0043] By controlling the plate 42 to rotate at a certain angle during or between oscillation cycles, the different sides and internal structure of the workpiece can be more evenly subjected to the oscillation force, avoiding uneven stress elimination that may be caused by a fixed orientation. Combined with X and Y bidirectional oscillation, the uniformity and thoroughness of the processing effect are improved.
[0044] For further details, please refer to Figure 4 A friction plate 70 is fixedly connected to the Y-axis motion table 41 shown, and the friction plate 70 is located on the side of the Y-axis motion table 41 facing the support plate 42.
[0045] In implementation, multiple friction plates 70 are fixedly laid or embedded on the top surface of the Y-axis motion table 41 facing the support plate 42. These friction plates 70 cover the critical load-bearing area of the contact zone between the Y-axis motion table 41 and the support plate 42. They can be fixed by screwing countersunk screws upwards from the bottom of the Y-axis motion table 41, or by machining a recessed area on the top surface of the Y-axis motion table 41 during manufacturing, embedding the friction plates 70 within it, and fixing them with pressure plates. The friction plates 70 are made of materials with a high coefficient of friction, good wear resistance, certain elasticity, and compressive strength, such as polyurethane or ultra-high molecular weight polyethylene.
[0046] In this way, the high-friction coefficient friction plate 70 significantly increases the maximum static friction between the contact surface of the support plate 42 and the Y-axis motion stage 41. When the equipment is subjected to high-frequency, directional oscillating inertial forces, it can effectively suppress any minor slippage or creep that may occur on the support plate 42. This ensures that the oscillation driving force from the Y-axis motion stage 41 to the support plate 42 and then to the workpiece can be transmitted directly and efficiently without loss, avoiding energy loss, asynchronous movement, and the resulting decrease in stress relief effect caused by sliding of the connection surface, fundamentally guaranteeing the effectiveness and consistency of the oscillation process.
[0047] For further details, please refer to Figure 4 The planar shape of the multiple friction plates 70 shown is arc-shaped, and the multiple friction plates 70 are mirror-distributed with respect to the center line of the Y-direction of the width of the motion table 41.
[0048] In this way, by symmetrically arranging the arc-shaped friction plates 70 along the centerline of the Y-axis motion table 41 in the Y-axis motion direction (i.e., the width direction), it is ensured that the frictional resistance experienced by both sides of the support plate 42 is completely symmetrical during the X-axis reciprocating oscillation. This fundamentally eliminates the yaw that would cause the support plate 42 to move in the X-axis direction, ensuring the high linearity and repeatability of the X-axis motion trajectory, and providing a basis for uniform and effective stress relief. Furthermore, the arc-shaped friction plates 70 also provide a stable constraint on the support plate 42 for the Y-axis motion.
[0049] For further details, please refer to Figure 1 , Figure 2 and Figure 4 As shown, a set of locking and positioning holes 80 are provided on the Y-axis motion table 41 and the support plate 42.
[0050] In this way, when the equipment is being maintained, cleaned, or shut down for an extended period, inserting the positioning pin can mechanically prevent the tray 42 from moving accidentally, ensuring safety.
