Description

Technical Field

[0001] This invention relates to the technical field of chemical fiber head bearing processing equipment, specifically a heat treatment and quenching fixture for the outer ring of a chemical fiber head bearing. Background Technology

[0002] In the heat treatment and quenching process of chemical fiber head bearing outer rings, quenching fixtures are required to achieve precise positioning, uniform heating, and rapid cooling. Traditional quenching fixtures typically employ a single clamping mechanism with a fixed material changing area. The workflow is as follows: the clamping mechanism picks up the workpiece from the material changing area, moves it to the processing area for quenching, and then returns to the material changing area to release the processed workpiece and pick up a new one. However, the actions of the processing area and the material changing area must alternate during this process, resulting in the processing area being idle during the movement and material changing of the clamping mechanism. This causes production cycle interruptions and severely restricts continuous production efficiency.

[0003] Specifically, the existing technology has the following drawbacks: when the clamping mechanism returns to the material changing area with the processed workpiece for unloading and retrieving, the processing area is forced to wait because there are no workpieces to process; conversely, when the clamping mechanism enters the processing area with the workpiece to be processed, the material changing area is idle. This single-threaded operation mode leads to insufficient equipment utilization and the work efficiency needs to be improved.

[0004] Therefore, it is necessary to provide a new heat treatment and quenching fixture for the outer ring of a chemical fiber head bearing to solve the above-mentioned technical problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a heat treatment quenching fixture for the outer ring of a chemical fiber head bearing, so as to realize the parallel operation of the processing area and the material changing area, eliminate the idle waiting time of the equipment, and improve the quenching efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides a heat treatment quenching fixture for the outer ring of a chemical fiber head bearing, comprising a quenching device body and a first material changing area and a second material changing area respectively disposed on both sides of the quenching device body. The quenching device body includes a frame, a feeding platform disposed on the frame, and a quenching head disposed on the frame above the feeding platform for cooperating with the feeding platform to quench the workpiece. The frame is also provided with a conveying component for conveying the workpiece and a clamping component disposed on the conveying component. The first material changing area and the second material changing area are each provided with a feeding component for releasing the workpiece to be processed and a recycling box for receiving the processed workpiece.

[0007] The material handling component includes a base plate mounted on the frame and a movable table slidably mounted on the base plate. Two clamping components are mounted on the movable table. When either of the two clamping components is located in the first material changing area or the second material changing area, the other clamping component is located at the unloading platform, so that the movable table can transfer the workpiece when it reciprocates on the base plate.

[0008] The clamping component includes a first clamping plate and a second clamping plate slidably disposed on the movable table. When the first clamping plate and the second clamping plate are in close contact with each other, they can bear the workpiece. A bidirectional screw is rotatably connected to the movable table for driving the first clamping plate and the second clamping plate to move closer to each other or further away from each other to complete the switching of clamping and releasing the workpiece.

[0009] The feeding component includes a feeding bin located above the recycling bin and a baffle plate slidably located at the bottom of the feeding bin. The feeding bin has openings at both the top and bottom, and multiple workpieces are placed inside the feeding bin. An insert plate is fixedly connected above the baffle plate via a connecting rod. The baffle plate and the insert plate are offset in the vertical projection direction. The insert plate is used to release the workpieces to the clamping component when the component moves.

[0010] Preferably, a first motor is fixedly connected to the movable platform, a gear is fixedly connected to the output end of the first motor, a rack is fixedly connected to the base plate, the gear and the rack are meshed, a slide bar with an inverted T-shaped cross section is fixedly connected to the bottom of the movable platform, and a movable groove for the slide bar to move is provided on the base plate. The length of the movable groove is the same as the distance between the two recycling bins. The first motor is used to drive the gear to rotate when started, so as to drive the movable platform to move along the movable groove.

[0011] Preferably, the clamping ends of the first clamping plate and the second clamping plate are both arc-shaped, and the bottom of the clamping ends of the first clamping plate and the second clamping plate are both provided with a bearing plate. The opposite surfaces of the two bearing plates are provided with a first guide slope that is inclined. The bottom of the first clamping plate and the second clamping plate are at the same height as the top of the unloading table. The first guide slope is used to lift and clamp the processed workpiece from the unloading table when the first clamping plate and the second clamping plate are close to each other.

[0012] Preferably, the threads at both ends of the bidirectional screw are reversed, and both ends of the bidirectional screw are connected to mirror-shaped threaded sleeves via ball screw pairs. The two threaded sleeves are respectively fixedly connected to the first clamping plate and the second clamping plate. A rotating rod is fixedly connected between the bidirectional screws of the two clamping components. A second motor for driving the two bidirectional screws to rotate is fixedly connected to the movable platform. A first slider with a T-shaped cross-section is fixedly connected to both the first clamping plate and the second clamping plate. A first groove for sliding the first slider is provided on the movable platform.

[0013] Preferably, the distance between the feeding component and the unloading platform is the same as the distance between the two clamping components, such that when one clamping component is located at the movable platform, the other clamping component is located at the feeding component in the first material changing area or the second material changing area.

[0014] Preferably, a second slider with a cross-shaped cross section is fixedly connected to both sides of the insert plate, and both second sliders are fixedly connected to the connecting rod. A second groove for sliding the second sliders is provided on the feeding bin. A third slider with an inverted T-shaped cross section is fixedly connected to both sides of the top of the baffle plate. A third groove adapted to the size of the third slider is provided on the feeding bin.

[0015] Preferably, the distance between the insert plate and the baffle plate is the same as the height of the workpiece. The insert plate has a second guide slope with an inclined surface on the side near the baffle plate. The second guide slope is used to lift and support multiple workpieces above the bottom workpiece when the insert plate approaches the workpiece, so as to ensure that the baffle plate releases one workpiece exactly when it moves back and forth for one stroke. The first end of the baffle plate away from the insert plate is fixedly connected to a connecting plate. An electric push rod for driving the baffle plate to move is fixedly connected to the unloading bin.

[0016] Preferably, the interior of the unloading bin is square, the side length of the square is the same as the outer diameter of the workpiece, and the bottom of the baffle plate is at the same height as the top of the first clamping plate and the second clamping plate, so that when the clamping component moves to the bottom of the unloading bin, it can just carry the workpiece released by the loading component.

[0018] 1. The heat treatment quenching fixture for the outer ring of the chemical fiber head bearing proposed in this invention achieves synchronous operation of quenching in the processing area and loading / unloading in the material changing area through the reciprocating movement of the movable table and the coordination of two sets of clamping components.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] Please see Figures 1 to 8As shown in the figure, the heat treatment quenching fixture for the outer ring of a chemical fiber head bearing provided in this embodiment of the invention includes a quenching device body 1 and a first material changing area 14 and a second material changing area 15 respectively disposed on both sides of the quenching device body 1. The quenching device body 1 includes a frame 11, a feeding platform 12 disposed on the frame 11, and a quenching head 13 disposed on the frame 11 above the feeding platform 12 for cooperating with the feeding platform 12 to quench the workpiece. The frame 11 is also provided with a conveying component 2 for conveying the workpiece and a clamping component 3 disposed on the conveying component 2. The first material changing area 14 and the second material changing area 15 are both provided with a feeding component 4 for releasing the workpiece to be processed and a recycling box 101 for receiving the processed workpiece.

[0039] like Figure 1 As shown, the symmetrical layout of the dual material changing areas enables parallel operation of the processing area and the material changing area, avoiding idle waiting due to single-threaded operation and improving continuous production efficiency.

[0040] The material handling component 2 includes a base plate 21 mounted on the frame 11 and a movable table 211 slidably mounted on the base plate 21. The movable table 211 is equipped with two clamping components 3. When either clamping component 3 is located at the first material changing area 14 or the second material changing area 15, the other clamping component 3 is located at the unloading platform 12. This allows the movable table 211 to transfer the workpiece when it reciprocates on the base plate 21. The movable table 211 synchronously completes the unloading of the processed workpiece and the loading of the workpiece to be processed through reciprocating movement. Its stroke matches the spacing of the material changing areas, ensuring that the two sets of clamping components 3 can seamlessly switch positions during movement, eliminating processing interruptions and greatly improving material handling efficiency.

[0041] In addition, the clamping component 3 includes a first clamping plate 31 and a second clamping plate 32 that are slidably disposed on the movable table 211. When the first clamping plate 31 and the second clamping plate 32 are in close contact with each other, they can bear the workpiece. A bidirectional screw 36 is rotatably connected to the movable table 211 for driving the first clamping plate 31 and the second clamping plate 32 to move closer to each other or further away from each other to complete the switching of clamping and releasing the workpiece.

[0042] In addition, the feeding component 4 includes a feeding bin 41 set above the recycling bin 101 and a baffle plate 42 slidably set at the bottom of the feeding bin 41. The feeding bin 41 is open at both the top and bottom, and multiple workpieces are placed inside the feeding bin 41. An insert plate 43 is fixedly connected above the baffle plate 42 by a connecting rod 421. The baffle plate 42 and the insert plate 43 are staggered in the vertical projection direction. The insert plate 43 is used to release the workpiece to the clamping component 3 when it moves. With this configuration, the baffle plate 42 and the insert plate 43 are linked together. When the electric push rod 49 drives the insert plate 43 to move, the second guide slope 431 lifts the stacked workpieces, releasing only the bottom single workpiece to the clamping component 3, thus completely solving the problem of multiple workpieces getting stuck. The internal dimensions of the feeding bin 41 are consistent with the outer diameter of the workpiece, ensuring the stability of the workpiece when it falls vertically.

[0043] Specifically, a first motor 22 is fixedly connected to the movable platform 211, and a gear 23 is fixedly connected to the output end of the first motor 22. A rack 24 is fixedly connected to the base plate 21, and the gear 23 and rack 24 are meshed together. A slide bar 25 with an inverted T-shaped cross-section is fixedly connected to the bottom of the movable platform 211. A movable groove 26 for the slide bar 25 to move is provided on the base plate 21. The length of the movable groove 26 is the same as the distance between the two recycling bins 101. The first motor 22 is used to drive the gear 23 to rotate when started, thereby driving the movable platform 211 to move along the movable groove 26. This configuration, through the first motor 22 driving the gear 23 to mesh with the rack 24, provides high-precision, high-load linear transmission, ensuring stable movement of the movable table 211 under high-temperature conditions and avoiding the problems of slippage or wear of traditional chain or belt drives. In addition, the cooperation between the slide bar 25 and the groove restricts the movable table 211 to move only in one direction, preventing deviation or vibration, ensuring accurate alignment of the clamping component 3 with the processing area and the material changing area. Furthermore, it can also ensure that the travel of the movable table 211 is consistent with the distance between the two material changing areas, avoiding overshoot or insufficient travel and improving material changing efficiency.

[0044] Secondly, the clamping ends of the first clamping plate 31 and the second clamping plate 32 are both arc-shaped. The bottom of the clamping ends of the first clamping plate 31 and the second clamping plate 32 are both provided with a bearing plate 301. The opposite surfaces of the two bearing plates 301 are provided with a first guide slope 302 with an inclined surface. The bottom of the first clamping plate 31 and the second clamping plate 32 are at the same height as the top of the unloading table 12. The first guide slope 302 is used to lift and clamp the processed workpiece from the unloading table 12 when the first clamping plate 31 and the second clamping plate 32 are close to each other. When the clamping plates are closed, the inclined guide slope gradually lifts the workpiece from the unloading table 12 and positions it in the center, eliminating the error of manual placement. The bearing plate 301 provides stable support to prevent the workpiece from shaking during movement. In addition, the bottom of the clamping plate is flush with the unloading table 12 to ensure seamless connection when the workpiece is transferred, avoiding collision or positioning deviation due to height difference.

[0045] Furthermore, the threads at both ends of the bidirectional screw 36 are reversed, and both ends of the bidirectional screw 36 are connected to mirror-shaped threaded sleeves 37 via ball screw pairs. The two threaded sleeves 37 are fixedly connected to the first clamping plate 31 and the second clamping plate 32, respectively. A rotating rod 38 is fixedly connected between the bidirectional screws 36 of the two clamping components 3. A second motor 35 for driving the two bidirectional screws 36 to rotate is fixedly connected to the movable table 211. A first slider 33 with a T-shaped cross section is fixedly connected to both the first clamping plate 31 and the second clamping plate 32. A first sliding groove 34 for sliding the first slider 33 is provided on the movable table 211. This arrangement enables the two clamping plates to move synchronously in opposite directions, avoiding workpiece tilting caused by unilateral pressure. By driving the bidirectional screws 36 of the two clamping components 3 with a single second motor 35, the movement of the two sets of clamping plates is completely synchronized, improving the consistency of the material changing rhythm. In addition, the clamping plates are restricted to moving only in a straight line to prevent the bidirectional screws 36 from jamming due to uneven force, while also enhancing structural rigidity.

[0046] Furthermore, the distance between the feeding component 4 and the unloading platform 12 is the same as the distance between the two clamping components 3, so that when one clamping component 3 is located at the movable platform 211, the other clamping component 3 is exactly located at the feeding component 4 in the first material changing area 14 or the second material changing area 15. Through the precise matching of the station spacing, it is ensured that the station switching between the processing area and the material changing area can be completed in a single movement of the movable platform 211 without multiple adjustments, thus shortening the cycle time.

[0047] Secondly, two second sliders 44 with cross-shaped cross sections are fixedly connected to both sides of the insert plate 43. Both second sliders 44 are fixedly connected to the connecting rod 421. A second slide groove 45 for sliding the second sliders 44 is provided on the feeding bin 41. A third slider 46 with an inverted T-shaped cross section is fixedly connected to both sides of the top of the baffle plate 42. A third slide groove 47 that matches the size of the third slider 46 is provided on the feeding bin 41. This arrangement can ensure that the misalignment linkage between the insert plate 43 and the baffle plate 42 is precise and controllable.

[0048] Secondly, the distance between the insert plate 43 and the baffle plate 42 is the same as the height of the workpiece. The side of the insert plate 43 near the baffle plate 42 is provided with a second guide slope 431 with an inclined surface. The second guide slope 431 is used to lift and support multiple workpieces above the bottom workpiece when the insert plate 43 is close to the workpiece, so as to ensure that the baffle plate 42 releases one workpiece exactly when it moves back and forth for one stroke. The first end of the baffle plate 42 away from the insert plate 43 is fixedly connected to a connecting plate 48. An electric push rod 49 for driving the baffle plate 42 to move is fixedly connected to the unloading bin 41. With this configuration, when the insert plate 43 moves, the inclined surface will lift the stacked workpieces, and only the bottom single workpiece will be released to the clamping component 3, which completely solves the problem of multiple workpieces jamming.

[0049] Specifically, the interior of the unloading bin 41 is square, with the side length of the square being the same as the outer diameter of the workpiece. The bottom of the baffle plate 42 is at the same height as the top of the first clamping plate 31 and the second clamping plate 32, so that when the clamping component 3 moves to the bottom of the unloading bin 41, it can just carry the workpiece released by the loading component 4. This setting restricts the workpieces to be stacked vertically in the bin, preventing tilting or misalignment and ensuring that the posture of the workpieces released each time is consistent.

[0050] Working principle:

[0051] In the initial state of the heat treatment and quenching fixture for the outer ring of the chemical fiber head bearing in this embodiment of the invention, the movable table 211 drives the gear 23 to mesh with the rack 24 of the base plate 21 through the first motor 22, thereby driving the inverted T-shaped slide bar 25 to move along the movable groove 26, so that the two sets of clamping components 3 are respectively located in the processing area of ​​the unloading table 12 and the first material changing area 14. When the clamping component 3 in the processing area drives the first clamping plate 31 and the second clamping plate 32 to close via the bidirectional screw 36 to clamp the processed workpiece, the loading component 4 in the first material changing area 14 drives the baffle plate 42 to move horizontally via the electric push rod 49, and the insert plate 43 is pulled vertically downward by the connecting rod 421. Its inclined second guide slope 431 lifts the stacked workpieces in the unloading bin 41 layer by layer, releasing only the bottom workpiece to be processed onto the clamping component 3 in the material changing area. Then the movable table 211 moves, and the original clamping component 3 in the processing area carries the processed workpiece into the second material changing area 15. The bidirectional screw 36 rotates in the opposite direction to drive the clamping plate to open, and the workpiece falls into the recycling box 101. At the same time, the original clamping component 3 in the first material changing area 14 carries the workpiece to be processed to the processing area and places the workpiece to be processed at the unloading table 12. During the reciprocating movement of the movable table 211, the bidirectional screws 36 of the two sets of clamping components 3 are synchronously driven by the rotating rod 38, ensuring that the clamping and releasing actions are precisely matched with the workstation switching rhythm. When the first guide slope 302 at the bottom of the clamping plate closes, it automatically lifts the workpiece to the center of the unloading table 12. The staggered linkage between the insert plate 43 and the baffle plate 42 ensures that only a single workpiece is released each time. This achieves seamless alternation of operation between the processing area and the material changing area, eliminating the equipment's idle waiting time and improving the quenching efficiency and positioning accuracy.
