Description

Technical Field

[0001] This invention relates to the field of optical axis quenching technology, specifically to a linear optical axis quenching device. Background Technology

[0002] Linear optical shafts are products that function as sliding bearings, enabling linear motion. The essential requirements for these linear motion systems include: simple design, optimal performance, low maintenance costs, use of rigorously selected, durable materials, high-frequency heat treatment, accurate outer diameter dimensions, roundness, straightness, and surface treatment. Linear optical shafts can be categorized as follows: ordinary linear optical shafts, chrome-plated linear optical shafts, chrome-plated flexible linear shafts, stainless steel linear shafts, and chrome-plated hollow shafts. Linear optical shafts are used in numerous linear motion systems such as cylinder rods, automatic precision printers, automatic cutting machines, and industrial robots.

[0003] Quenching involves heating steel to above its critical temperature (Ac3 for hypoeutectoid steel or Ac1 for hypereutectoid steel), holding it at that temperature, and then rapidly cooling it to below Ms (or isothermally near Ms) at a rate greater than the critical cooling rate. This process produces a martensitic or bainitic structure, aiming to improve the steel's hardness, wear resistance, and fatigue strength. Quenching can be categorized in several ways: by cooling medium (single-liquid quenching, double-liquid quenching, staged quenching, isothermal quenching, etc.) and by quenching depth (surface quenching, localized quenching, etc.). Linear optical shafts require quenching during machining, followed by appropriate cooling to eliminate internal stress.

[0004] Chinese patent document CN221566230U discloses a quenching and cooling device for producing self-drilling screws, comprising a functional box, a support box and a cooling pool fixedly mounted on the top of the functional box, the right side of the support box being fixedly connected to the left side of the cooling pool, a motor fixedly mounted on the bottom inner wall of the functional box, the motor output shaft extending into the cooling pool, and an agitation mechanism mounted on the motor output shaft; a reciprocating mechanism is provided between the support box and the functional box, a seat hole is opened on the right side of the support box, the seat hole being located above the cooling pool, and a drain pipe is provided on the right side of the cooling pool; the agitation mechanism includes an agitation seat and an agitation blade, the agitation seat being fixedly mounted on the motor output shaft, and the agitation blade being mounted on the agitation seat; the reciprocating mechanism includes a reciprocating lead screw and a lead screw seat, the reciprocating lead screw being rotatably mounted on the bottom inner wall of the functional box, the reciprocating lead screw being located to the left of the motor, the top end of the reciprocating lead screw being rotatably connected to the top inner wall of the support box, and a lead screw seat threaded onto the reciprocating lead screw, the right side of the lead screw seat extending to the outside of the support box, the lead screw seat being adapted to the seat hole, and the lead screw... A placement mechanism is provided on the right side of the base, a stabilizing mechanism is provided between the lead screw base and the support box, and a transmission mechanism is provided between the reciprocating lead screw and the motor output shaft. The placement mechanism includes a connecting plate and a placement basket. The connecting plate is fixedly installed on the right side of the lead screw base, and the placement basket is slidably installed in the cooling pool. The top left side of the placement basket is fixedly connected to the bottom of the connecting plate, and a sliding mechanism is provided between the placement basket and the cooling pool. The sliding mechanism includes a slider and a groove. Sliders are provided on both sides of the placement basket, and grooves are opened on both sides of the inner wall of the cooling pool. The sliders are slidably connected to the corresponding grooves. The stabilizing mechanism includes a stabilizing rod and a rod hole. The same stabilizing rod is fixedly installed on the top and bottom inner walls of the support box. The stabilizing rod is located on the left side of the reciprocating lead screw, and a rod hole is opened on the lead screw base. The stabilizing rod is slidably connected to the rod hole. The transmission mechanism includes two transmission wheels and a transmission belt. Transmission wheels are fixedly installed on both the reciprocating lead screw and the motor output shaft. Both transmission wheels are located in the function box, and the same transmission belt is sleeved on both transmission wheels.

[0005] During operation, coolant is first injected into the cooling pool through the pool opening. The screw is then placed into the placement basket, and the motor is started. The motor drives the agitator to rotate, which in turn drives the agitator blades to rotate. The agitator blades continuously agitate the coolant, ensuring full contact between the coolant and the screw, thus accelerating the quenching and cooling process. The motor drives the reciprocating lead screw to rotate via two drive wheels and a drive belt, causing the lead screw seat to move up and down. The connecting plate then moves the placement basket up and down, causing the screw to move up and down, thus enabling the screw to move up and down within the coolant.

[0006] In the aforementioned technology, when batch quenching and cooling workpieces, a box containing a large number of workpieces is placed in a cooling pool for quenching and cooling. The box typically contains multiple layers of workpieces. During quenching, when the workpieces at the top come into contact with the quenching liquid, the temperature of the quenching liquid has already risen, resulting in poor quenching effect. At the same time, the parts of the workpieces that come into contact with the box cannot come into contact with the quenching liquid in time during quenching, and the quenching effect at the contact points is also poor. Summary of the Invention

[0007] This invention provides a linear optical axis quenching device, which aims to solve the technical problems in the prior art when batch quenching and cooling workpieces. In this device, a box containing a large number of workpieces is placed in a cooling pool for quenching and cooling. The box typically contains multiple layers of workpieces. During quenching, when the workpieces at the top come into contact with the quenching liquid, the temperature of the quenching liquid has already risen, resulting in poor quenching effect. At the same time, the parts of the workpieces that come into contact with the box cannot come into contact with the quenching liquid in time during quenching, resulting in poor quenching effect at the contact points as well.

[0008] This invention discloses a linear optical axis quenching device, comprising a multi-layer placement rack and a cooling pool for cooling the linear optical axis. Each layer of the placement rack is slidably fitted along the length of the cooling pool. Multiple placement components for restricting the rolling of the linear optical axis are evenly distributed on each layer of the placement rack along the length of the cooling pool. A movable plate is provided on one side of each placement rack at the placement component. A hollow groove is formed inside the placement rack and below the movable plate. A push plate is slidably disposed in the hollow groove along the length of the cooling pool. The push plate is connected to the movable plate. An adjusting plate for pushing the linear optical axis to roll is rotatably disposed inside the placement rack. When the placement rack is pulled out along the length of the cooling pool, the push plate slides, causing the movable plate to insert into the hollow groove of the placement rack. The movable plate no longer restricts the rolling of the linear optical axis. When the placement rack enters the cooling pool, the steam generated during quenching causes the adjusting plate to rotate, and the adjusting plate pushes the linear optical axis to roll on the placement rack.

[0009] The beneficial effects are as follows: By setting up the placement rack, when the linear optical axis is quenched and cooled, the multi-layer placement rack is first unfolded along the length of the cooling pool, and multiple workpieces are placed in the multi-layer placement rack. Then, the unfolded multi-layer placement rack is hoisted into the cooling pool for cooling, so that each layer of the linear optical axis can be cooled in a timely and effective manner. The placement parts on the placement rack are used to restrict the rolling of the linear optical axis. After the multi-layer placement rack is unfolded along the length of the cooling pool, the push plate slides, and the movable plate moves downward by pushing the push plate. At this time, the movable plate no longer restricts the linear optical axis, and the linear optical axis can roll freely. When the placement rack comes into contact with the coolant in the cooling pool, the steam generated by quenching causes the adjusting plate to rotate. The adjusting plate can push the linear optical axis to roll, avoiding the inability of the contact part between the linear optical axis and the placement parts to be cooled in time, which would cause internal stress, thereby improving the quenching effect on the workpiece.

[0010] Preferably, each layer of the placement rack has a sliding groove at both ends along the width direction of the cooling pool on its upper surface. The sliding groove is arranged along the length direction of the cooling pool, and a steel roller is slidably arranged in the sliding groove. The steel roller is connected to the lower surface of the placement rack.

[0011] Beneficial effects: By setting up the chute and steel rollers, the steel rollers can slide in the chute when two adjacent shelves slide, thereby achieving efficient sliding adjustment of the multi-layer shelf.

[0012] Preferably, limiting grooves are also provided on the inner walls on both sides of the chute, and the rotating shaft of the steel roller extends into the limiting groove.

[0013] Beneficial effect: By setting the limiting groove, after the rotation shaft of the steel roller extends into the limiting groove, the vertical movement of the steel roller can be restricted, preventing the steel roller from sliding out of the groove in the vertical direction.

[0014] Preferably, each layer of the placement rack is provided with two support rods along the width direction of the cooling pool, and multiple placement components are arranged along the length direction of the support rods.

[0015] Preferably, the placement component further includes a fixing plate, with the linear optical axis placed between the fixing plate and the movable plate, and the fixing plate being triangular in shape.

[0016] Beneficial effects: By setting up the fixed plate and the movable plate, the linear optical axis can be limited. The linear optical axis is restricted to rolling on the support rod. When the multi-layer placement rack is unfolded, the displacement between the multi-layer placement racks is large and they will collide with each other. This process may cause the linear optical axis to fall off the support rod. At this time, the linear optical axis falling off may cause a safety accident. By setting up the placement component, the linear optical axis can be prevented from rolling and falling off the placement rack.

[0017] Preferably, the hollow groove is further provided with a plurality of receiving grooves extending to the top surface of the support rod, and the receiving grooves are connected to the hollow groove.

[0018] Preferably, an elastic element for driving the push plate to reset is also installed between the push plate and the hollow groove. One end of the elastic element is connected to the inner wall of the hollow groove, and the other end is connected to the push plate.

[0019] Beneficial effects: By setting up the elastic element, the push plate can compress the elastic element during the sliding process. When the push plate no longer compresses the elastic element, the elastic element can release the elastic restoring force, driving the push plate to slide and reset.

[0020] Preferably, the placement rack is provided with multiple liquid outlet holes at the bottom of the hollow tank.

[0021] Beneficial effect: By setting the liquid outlet hole, after the linear optical axis is processed and the placement frame is lifted out of the cooling pool, the coolant in the hollow tank can be discharged through the liquid outlet hole.

[0022] Preferably, the adjustment plate is provided with a counterweight, which is used to make the opening of the adjustment plate face upward.

[0023] Beneficial effects: By setting the counterweight, in the initial state, before the linear optical axis is placed in the placement frame, the counterweight can make the opening of the adjustment plate face the direction, which is convenient for placing the linear optical axis. After the linear optical axis is placed, the vertical plate of the adjustment plate changes from a horizontal state to a vertical state.

[0024] Preferably, each of the four corners of the placement rack is provided with a lifting hole, and a lifting component is provided on the placement rack, which passes through the lifting hole and connects to the placement rack.

[0025] Beneficial effects: The installation of lifting holes facilitates the connection between the lifting components and the placement frame, thereby enabling efficient processing of linear optical axes.

[0026] The beneficial effects of this invention are as follows: 1. In this invention, by setting up a placement rack, when the linear optical axis is quenched and cooled, the multi-layer placement rack is first unfolded along the length of the cooling pool, and multiple workpieces are placed in the multi-layer placement rack. Then, the unfolded multi-layer placement rack is hoisted into the cooling pool for cooling, so that each layer of linear optical axis can be cooled in a timely and effective manner. The placement parts on the placement rack are used to restrict the rolling of the linear optical axis. After the multi-layer placement rack is unfolded along the length of the cooling pool, the push plate slides, and the movable plate moves downward by pushing the push plate. At this time, the movable plate no longer restricts the linear optical axis, and the linear optical axis can roll freely. When the placement rack comes into contact with the coolant in the cooling pool, the quenching generates steam, which causes the adjusting plate to rotate. The adjusting plate can push the linear optical axis to roll, avoiding the inability of the contact part between the linear optical axis and the placement parts to be cooled in time, which would cause internal stress, thereby improving the quenching effect on the workpiece.

[0027] 2. In this invention, the use of grooves and steel rollers enables the steel rollers to slide within the grooves when two adjacent shelves slide, thereby achieving efficient sliding adjustment of the multi-layer shelf.

[0028] 3. In this invention, by setting the limiting groove, after the rotation shaft of the steel roller extends into the limiting groove, the vertical movement of the steel roller can be restricted, preventing the steel roller from sliding out of the groove in the vertical direction.

[0029] 4. In this invention, the linear optical axis can be limited by the setting of the fixed plate and the movable plate. The linear optical axis is restricted to rolling on the support rod. When the multi-layer placement rack is unfolded, the displacement between the multi-layer placement racks is large and they will collide with each other. This process may cause the linear optical axis to fall off the support rod. At this time, the falling of the linear optical axis may cause a safety accident. By setting the placement component, the linear optical axis can be prevented from rolling and falling off the placement rack.

[0030] 5. In this invention, by setting the elastic element, the push plate can compress the elastic element during the sliding process. When the push plate no longer compresses the elastic element, the elastic element can release the elastic restoring force and drive the push plate to slide and reset. Attached Figure Description

[0039] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] Reference Figures 1-7 The present invention discloses a linear optical axis quenching device, comprising a multi-layer placement rack 1 and a cooling pool 3 for cooling the linear optical axis. The placement rack 1 has three layers arranged vertically and is configured as an "I" shaped structure. Each layer of the placement rack 1 is slidably fitted together along the length of the cooling pool 3. The placement rack 1 is provided with a lifting component 5, and there are two sets of lifting components 5. Each set includes two lifting components 5. The bottom end of the lifting component 5 is connected to the placement rack 1, and the top end of the lifting component 5 is connected to a lifting mechanism (not shown in the figure). The lifting mechanism can be an electric hoist. When quenching and cooling processing of linear optical shafts is required, multiple linear optical shafts are first placed sequentially in a multi-layer placement rack 1. After the multi-layer placement rack 1 is placed, the lifting component 5 is connected to the placement rack 1, and then the lifting mechanism is started. The lifting mechanism drives the lifting component 5 to move, the lifting component 5 drives the placement rack 1 to move, and the placement rack 1 drives the linear optical shaft to move, thereby lifting the linear optical shaft to the cooling pool 3. Then, the linear optical shaft is lifted into the cooling pool 3, and the linear optical shaft is quenched and cooled in the cooling pool 3. After the linear optical shaft is processed, the lifting mechanism drives the lifting component 5 to move, the lifting component 5 drives the placement rack 1 to move, and the placement rack 1 is lifted out of the cooling pool 3. After the placement rack 1 is lifted out, the linear optical shaft in the multi-layer placement rack 1 is taken out, completing the processing of the linear optical shaft.

[0041] Reference Figure 1 , Figure 2 and Figure 3 Each layer of the placement rack 1 has four corners equipped with lifting holes 11. The bottom end of the lifting component 5 is equipped with a lifting rod, one end of which is threaded. This allows the lifting rod of the lifting component 5 to pass through the lifting hole 11 and connect with a nut via a threaded connection, thus facilitating the connection between the lifting component 5 and the placement rack 1. During the lifting operation, after the placement rack 1 removed from the quenching furnace is placed stably, one set of lifting components 5 is installed in the two lifting holes 11 of the lowest placement rack 1, and another set of lifting components 5 is installed in the two lifting holes 11 of the highest placement rack 1. The two sets of lifting components 5 are located at opposite ends of the length of the placement rack 1 (as shown in the diagram). Figure 1 (As shown); at this time, the bottommost set of lifting components 5 remains fixed, and then the top set of lifting components 5 moves away from the bottommost placement frame 1, causing the multi-layer placement frames 1 to slide relative to each other and unfold. After the multi-layer placement frames 1 are unfolded (their state is as shown) Figure 3 As shown, the placement frame 1 is placed in the cooling pool 3 for quenching and cooling by the hoisting mechanism. Multiple linear optical axes on each layer of the placement frame 1 are arranged in a line. At this time, during quenching and cooling, the heat generated by each linear optical axis will not affect each other. At the same time, during quenching, the unfolded placement frame 1 can be swayed along the length of the cooling pool 3 by the hoisting component 5 to achieve effective cooling.

[0042] Reference Figure 2 , Figure 3 and Figure 4Each shelf 1 has a rectangular groove 12 on its upper surface, extending along the width of the cooling pool 3. Both ends of the groove 12 are sealed. The groove 12 extends along the length of the cooling pool 3. A steel roller 13 slides within the groove 12, and a mounting base is rotatably fitted onto each roller 13. The mounting base is fixedly connected to the lower surface of the shelf 1. The steel roller 13 rotates with the shelf 1 via the mounting base. When the shelf 1 slides, it drives the mounting base to slide, which in turn drives the steel roller 13 to slide within the groove 12. Limiting grooves 14 are also provided on the inner walls of both sides of the groove 12, forming a cross shape. The rotating shaft of the steel roller 13 extends into the limiting groove 14. The rotating shaft can only move along the length of the limiting groove 14, and the rotating shaft of the steel roller 13 cannot move along the height of the limiting groove 14. When the lowest placement rack 1 is fixed, the upper placement rack 1 can drive the steel roller 13 to slide in the slide groove 12 through the mounting seat during the sliding process. At the same time, the rotating shaft of the steel roller 13 slides in the limiting groove 14 to adjust the sliding of the placement rack 1. When the steel roller 13 on each layer of the placement rack 1 moves to the end of the slide groove 12 that contacts the steel roller 13, the multi-layer placement rack 1 unfolds. At this time, the placement rack 1 is stopped from being pulled. The setting of the limiting groove 14 can limit the vertical movement of the steel roller 13 and prevent the steel roller 13 from sliding out of the slide groove 12.

[0043] Reference Figure 2 , Figure 5 and Figure 6Each layer of the placement rack 1 has multiple placement components 2 evenly distributed along the length of the cooling pool 3 to restrict the rolling of the linear optical axis. Each placement component 2 includes a movable plate 21, which is mounted on the placement rack 1. Two sets of movable plates 21 are arranged along the width of the placement rack 1, each set including multiple movable plates 21 along the length of the placement rack 1. The multiple movable plates 21 are evenly spaced. A hollow groove 17 is provided inside the placement rack 1 below the movable plates 21. A push plate 4 is slidably arranged in the hollow groove 17 along the length of the cooling pool 3, and is connected to the movable plates 21. An adjusting plate 6 for pushing the linear optical axis to roll is rotatably arranged inside the placement rack 1. The adjusting plate 6 is an "L"-shaped plate and includes a vertical plate. The horizontal and vertical plates are set perpendicular to each other. When the hoisting component 5 pulls the placement frame 1 to unfold along the length of the cooling pool 3, it drives the push plate 4 to slide, causing the movable plate 21 to insert into the hollow groove 17 of the placement frame 1. At this time, the movable plate 21 no longer restricts the rolling of the linear optical axis. When the placement frame 1 enters the cooling pool 3, the linear optical axis comes into contact with the coolant in the cooling pool 3, and a large amount of steam is generated instantly. At this time, the steam will push the adjusting plate 6 to rotate. The adjusting plate 6 pushes the linear optical axis to rotate on the placement frame 1. The linear optical axis rolls in the coolant for a short time when it comes into contact with the coolant, which can avoid the part of the linear optical axis that comes into contact with the placement component 2 from not cooling in time and generating excessive local stress. The above operation has a better quenching and cooling effect.

[0044] Reference Figure 3 , Figure 6 and Figure 7 A counterweight 7 is fixedly installed on the adjusting plate 6. The counterweight 7 is used to make the opening of the adjusting plate 6 face upwards, so that when no linear optical axis is placed in the placement frame 1, the opening of the adjusting plate 6 faces upwards under the action of the counterweight 7 (its state is as follows). Figure 5 As shown), when placing the linear optical axis, start placing the linear optical axis from the bottommost placement rack 1. After the linear optical axis on each layer of placement rack 1 is placed, place the linear optical axis on the next layer of placement rack 1. When the linear optical axis is placed on the adjustment plate 6, the vertical plate of the adjustment plate 6 changes from a horizontal state to a vertical state (its state is as shown). Figure 6 (As shown).

[0045] Reference Figure 3 , Figure 6 and Figure 7Each layer of the placement rack 1 is provided with two support rods 15 along the width direction of the cooling pool 3. The support rods 15 are provided along the length direction of the placement rack 1. When the linear optical axis is placed in the placement rack 1, the linear optical axis is placed perpendicular to the support rods 15. Multiple placement components 2 are arranged along the length direction of the support rods 15. The placement component 2 also includes a fixing plate 22, which is set on the placement rack 1. In the initial state, the linear optical axis is placed between the fixing plate 22 and the movable plate 21. The fixing plate 22 is triangular.

[0046] Reference Figure 3 , Figure 6 and Figure 7 When placing the linear optical axis, it is placed between the fixed plate 22 and the movable plate 21. The linear optical axis is restricted to rolling on the support rod 15. When the multi-layer placement rack 1 is unfolded by the hoisting component 5, the displacement between the placement racks 1 is large and they collide with each other. This process may cause the linear optical axis to fall off the support rod 15. At this time, the fall of the linear optical axis may cause a safety accident. The placement component 2 is used to prevent the linear optical axis from falling off the placement rack 1.

[0047] Reference Figure 3 , Figure 6 and Figure 7 The hollow trough 17 is also provided with multiple receiving slots 16 that extend to the top surface of the support rod 15. The receiving slots 16 are connected to the hollow trough 17. The push plate 4 is slidably disposed in the hollow trough 17. One side of the fixed plate 22 is in contact with the linear optical axis, and the other side is in contact with the receiving slot 16. After the multi-layer placement frame 1 is unfolded, the upper placement frame 1 pushes the push plate 4 on the lower placement frame 1 to move. The push plate 4 pushes the movable plate 21 to move downward. At this time, the movable plate 21 no longer restricts the horizontal rolling of the linear optical axis. At the same time, in the subsequent hoisting process, the operator needs to move all the hoisting parts 5 in sync so that there is no more displacement between the multi-layer placement frames 1. The operator only needs to control the moving speed of the hoisting parts 5 to avoid the linear optical axis from falling.

[0048] Reference Figure 5 , Figure 6 and Figure 7 An elastic element 18 for resetting the push plate 4 is installed between the push plate 4 and the hollow groove 17. The elastic element 18 is a spring and is horizontally set. One end of the elastic element 18 is fixedly connected to the inner wall of the placement frame 1 located in the hollow groove 17, and the other end of the elastic element 18 is fixedly connected to the push plate 4. When the push plate 4 slides and slides closer to the elastic element 18, the push plate 4 can compress the elastic element 18 and continue to slide. When the push plate 4 no longer compresses the elastic element 18, the elastic element 18 releases its elastic restoring force, causing the push plate 4 to slide away from the elastic element 18 to reset.

[0049] Reference Figure 5 , Figure 6 and Figure 7 After the linear optical axis quenching and cooling are completed, when the placement frame 1 is lifted out of the cooling pool 3 by the lifting device 5, the uppermost placement frame 1 is pulled by the lifting device 5 to slide towards the placement frame 1 closest to the bottom, until all the placement frames 1 are stacked (their state is as follows). Figure 2 As shown), after the hoisting component 5 moves a certain distance, the push plate 4 will lose the pressure exerted on it by the placement frame 1 above. Within a short distance of movement, the hoisting component 5 can be moved slowly to avoid large swaying of the placement frame 1. When the push plate 4 is no longer pushed, the elastic element 18 can drive the push plate 4 to move in the opposite direction. The push plate 4 causes the movable plate 21 to move upward. At this time, the linear optical axis rolls and re-attaches to the fixed plate 22. The linear optical axis is restricted within the placement component 2. At this time, the operator can quickly move the hoisting component 5 to move the placement frame 1 to the place to be placed.

[0050] Reference Figure 5 , Figure 6 and Figure 7 The placement frame 1 is provided with multiple liquid outlet holes 19 at the bottom of the hollow tank 17. The liquid outlet holes 19 are used to discharge the coolant in the hollow tank 17 after the linear optical axis is processed and the placement frame 1 is lifted out of the cooling pool 3. The multiple liquid outlet holes 19 are evenly and spaced on the placement frame 1.

[0051] The implementation principle of the linear optical axis quenching device of the present invention is as follows: When a linear optical axis needs to be quenched and cooled, multiple linear optical axes are placed first. During placement, the linear optical axes are placed starting from the bottommost placement rack 1. After the linear optical axes on each layer of placement rack 1 are placed, the linear optical axes on the next layer of placement rack 1 are placed. In the initial state, the opening of the adjusting plate 6 faces upward (its state is as follows). Figure 5 As shown), when the linear optical axis is placed on the adjustment plate 6, the vertical plate of the adjustment plate 6 changes from a horizontal state to a vertical state; After the multi-layer placement rack 1 is placed, the lifting component 5 is connected to the placement rack 1. When connecting, one set of lifting components 5 is installed in the two lifting holes 11 of the bottom placement rack 1, and another set of lifting components 5 is installed in the two lifting holes 11 of the top placement rack 1. The two sets of lifting components 5 are located at both ends of the length direction of the placement rack 1. After the hoisting components 5 are installed, the lower set of hoisting components 5 is fixed in place, and then the upper set of hoisting components 5 moves away from the lowest placement frame 1. The mounting base can drive the steel rollers 13 to slide in the slide groove 12. At the same time, the rotation shaft of the steel rollers 13 slides in the limiting groove 14. After the steel rollers 13 on each layer of the placement frame 1 move to the end of the slide groove 12 that contacts the steel rollers 13, the multi-layer placement frame 1 gradually unfolds. The vertical movement of the steel rollers 13 is limited by the limiting groove 14 to prevent the steel rollers 13 from sliding out of the slide groove 12. When the multi-layer shelf 1 is unfolded (its state is as follows) Figure 3 As shown), the push plate 4 slides and moves closer to the elastic member 18. When the push plate 4 slides, it can compress the elastic member 18 and continue to slide. While the push plate 4 slides, the movable plate 21 is inserted into the hollow groove 17 of the placement frame 1. The movable plate 21 no longer restricts the rolling of the linear optical axis. Then, the hoisting mechanism is activated, which drives the hoisting component 5 to move. The hoisting component 5 drives the placement frame 1 to move, placing the placement frame 1 into the cooling pool 3. When the placement frame 1 enters the cooling pool 3, the steam generated by quenching causes the adjusting plate 6 to rotate. The adjusting plate 6 pushes the linear optical shaft to roll on the placement frame 1. At this time, the linear optical shaft is quenched and cooled in the cooling pool 3. The multiple linear optical shafts on each layer of the placement frame 1 are arranged in a straight line. During quenching and cooling, the heat generated by quenching between each linear optical shaft will not affect each other. At the same time, during quenching, the unfolded placement frame 1 can be swung along the length of the cooling pool 3 by the hoisting component 5 to achieve effective cooling. After the linear optical axis is processed, the lifting mechanism drives the lifting component 5 to move, and the lifting component 5 drives the placement frame 1 to move, lifting the placement frame 1 out of the cooling pool 3. Then, the linear optical axis in the multi-layer placement frame 1 is taken out, completing the processing of the linear optical axis.

[0052] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
