Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a quenching tool for excavator track carburizing bushings. Background Technology

[0002] In the production and processing of excavator track carburizing sleeves, quenching is a key step to ensure their mechanical properties and service life. The carburizing sleeve needs to be heated first using quenching fixtures, and then cooled down after heating.

[0003] Chinese patent CN222524604U discloses a bulldozer track carburizing sleeve quenching fixture, including: a base plate, a heating mechanism, a cooling box, and a spraying mechanism.

[0004] In the aforementioned patent document, the two housings used to hold the heating element are connected by bolt fasteners. Each time the carburizing sleeve is placed or removed, the bolts need to be tightened one by one to open and close the housing. This not only increases the labor intensity of workers but also significantly prolongs the auxiliary time of the quenching process, thus restricting the improvement of production efficiency. At the same time, manually transferring the high-temperature carburizing sleeve to the cooling box can easily cause burns to the operators due to the high-temperature parts, posing a significant safety risk. Utility Model Content

[0005] The purpose of this utility model is to solve the following shortcomings in the existing technology. In the existing tracked carburizing sleeve quenching fixture, the two shells used to load the elements to be heated are connected by bolt fasteners. Each time the carburizing sleeve is placed or removed, the bolts need to be tightened one by one to open and close the shells. This not only increases the labor intensity of workers, but also significantly prolongs the auxiliary time of the quenching process, which restricts the improvement of production efficiency. At the same time, manually transferring the high-temperature carburizing sleeve to the cooling box can easily cause the operator to be burned by the high-temperature parts, which poses a great safety risk. Therefore, a tracked excavator carburizing sleeve quenching fixture is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A track-type carburizing bushing quenching fixture for excavators includes a base plate. Mounting plates are symmetrically fixed on the upper surface of the base plate. Two mounting plates have rotating shafts on their adjacent sides. A mounting shell is fixedly installed between the two rotating shafts. An opening is provided on the surface of the mounting shell. A shell cover is rotatably connected to the opening wall via the rotating shaft. Multiple first rectangular blocks are equidistantly fixed on the surface of the shell cover away from the rotating shaft. Multiple second rectangular blocks, each designed to abut against the first rectangular blocks, are equidistantly fixed on the surface of the mounting shell. A rectangular opening is provided on the upper surface of the middle second rectangular block. A first threaded rod is horizontally rotatably installed within the rectangular opening. A slider is threaded onto the first threaded rod. Three rectangular frames are provided on one side of the mounting shell. Adjacent rectangular frames are fixedly connected by a connecting rod. Through-holes are provided on the left and right walls of the rectangular opening. The slider passes through two through-holes and is fixedly connected to the inner wall of the middle rectangular frame. One end of the first threaded rod passes through the second rectangular block and is fixedly mounted with an adjusting wheel. A heater is fixedly installed on the surface of the mounting shell.

[0008] The rotating shaft is controlled to rotate by a drive assembly, and a cooling box located directly below the mounting shell is fixed on the upper surface of the base plate.

[0009] Preferably, the drive assembly includes an L-shaped plate fixedly mounted on the surface of one of the mounting plates and a drive motor fixedly mounted on the surface of the L-shaped plate, wherein the output shaft of the drive motor passes through the mounting plate and is fixedly connected to one of the rotating shafts.

[0010] Preferably, the upper surface of the cooling box is provided with a cooling groove with a semi-circular longitudinal section. A rotating rod is horizontally rotatably installed in the cooling groove. A receiving plate is fixedly sleeved on the rotating rod. The surface of the receiving plate is provided with multiple through holes. A sliding groove communicating with the cooling groove is provided on one side of the cooling box. A collection frame is slidably inserted in the sliding groove. The rotating rod is controlled to reciprocate through a transmission assembly.

[0011] Preferably, the transmission assembly includes a reciprocating lead screw horizontally rotatably mounted on the surface of one of the mounting plates, a slide plate threaded onto the reciprocating lead screw, and a second threaded rod fixedly connected to the slide plate. Both the reciprocating lead screw and the output shaft of the drive motor are fixedly fitted with sprockets, and chains are meshed and wound on the two sprockets. One end of the rotating rod extends out of the cooling box and has a threaded groove adapted to the second threaded rod. One end of the second threaded rod is threaded into the threaded groove.

[0012] Preferably, a water tank is fixedly installed on the upper surface of the base plate, and the water tank is filled with cooling water. A fixing ring is fixedly installed on the surface of one of the mounting plates via an L-shaped connecting rod. An mounting rod is fixedly installed inside the fixing ring. One end of the mounting rod has a water groove. A piston rod is slidably inserted into the water groove. A water pipe is fixedly installed on one end of the mounting rod via a water outlet pipe. One end of the water pipe passes through one of the mounting plates. Multiple water distribution pipes are fixedly installed on the lower surface of the water pipe. The bottom ends of the water distribution pipes extend into the cooling groove. The mounting rod is fixedly connected to the water tank via a water inlet pipe. Both the water inlet pipe and the water outlet pipe are equipped with one-way valves. An L-shaped block is fixedly installed on one end of the piston rod. The L-shaped block is fixedly connected to the slide plate via a fixing rod.

[0013] Preferably, the one-way valve in the outlet pipe is directed from the water tank to the water pipe, and the one-way valve in the inlet pipe is directed from the water tank to the water trough.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The tooling adopts a rotating connection structure between the mounting shell and the shell cover, and is equipped with a first rectangular block, a second rectangular block and a locking assembly consisting of a first threaded rod, a slider and a rectangular frame. This replaces the traditional bolt fixing method. The shell cover can be quickly opened and locked by simply rotating the adjusting wheel. There is no need to tighten the bolts one by one. This greatly reduces the auxiliary time for placing and removing the carburizing sleeve, reduces the labor intensity of workers, and effectively improves the overall efficiency of the quenching process.

[0016] 2. By controlling the rotation of the shaft with the help of the drive component, the entire mounting shell can be flipped over, allowing the heated carburizing sleeve to fall directly into the cooling box below without manual transfer. This design fundamentally eliminates the safety hazard of hot parts burning operators and provides reliable safety for the production process.

[0017] 3. The receiving plate inside the cooling box can be reciprocated by the transmission assembly. With the through holes on the surface, the carburizing sleeve can be in full contact with the cooling water, improving the cooling uniformity. At the same time, the water tank can continuously replenish the cooling tank with cooling water through the pumping structure composed of the mounting rod, piston rod, etc., ensuring stable cooling effect and helping to improve the quenching quality of the carburizing sleeve.

[0018] 4. The drive motor can not only control the rotation of the mounting shell, but also drive the reciprocating screw to rotate through the sprocket and chain, thereby realizing the rotation of the receiving plate and the pumping of cooling water. The components work together, reducing manual intervention and without generating additional electricity costs, making the quenching process more automated and continuous, which meets the needs of modern production.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0030] Reference Figures 1-4 A track-type carburizing bushing quenching fixture for excavators includes a base plate 1. Mounting plates 2 are symmetrically fixed on the upper surface of the base plate 1. Rotating shafts 3 are rotatably mounted on the sides of the two mounting plates 2 that are close to each other. A mounting shell 10 is fixedly installed between the two rotating shafts 3. An opening is formed on the surface of the mounting shell 10. A shell cover 11 is rotatably connected to the opening wall via the rotating shaft. Multiple first rectangular blocks 12 are equidistantly fixed on the surface of the shell cover 11 away from the rotating shaft. Multiple second rectangular blocks 13, each designed to abut against the multiple first rectangular blocks 12, are equidistantly fixed on the surface of the mounting shell 10. The first rectangular blocks 12 and the second rectangular blocks 13 have the same length. Figure 8 As shown, the length of the second rectangular block 13 located in the middle is greater than the length of the first rectangular block 12 and the other two second rectangular blocks 13. A rectangular opening is provided on the upper surface of the second rectangular block 13 located in the middle. A first threaded rod 14 is horizontally rotatably installed in the rectangular opening. A slider 15 is threaded onto the first threaded rod 14. Three rectangular frames 16 are provided on one side of the mounting shell 10. Two adjacent rectangular frames 16 are fixedly connected by a connecting rod. Through holes 17 are provided on the left and right walls of the rectangular opening. The two ends of the slider 15 pass through the two through holes 17 respectively and are fixedly connected to the inner frame wall of the rectangular frame 16 located in the middle. One end of the first threaded rod 14 passes through the second rectangular block 13 and is fixedly installed with an adjusting wheel. A heater 36 is fixedly installed on the surface of the mounting shell 10. The heater 36 is used to heat the carburizing sleeve inside the mounting shell 10 (the heater 36 is disclosed in publication number CN222524604U, patent name is a bulldozer track type carburizing sleeve quenching tool, which belongs to the prior art, and its working principle will not be described in detail here).

[0031] Reference Figure 1 The rotating shaft 3 is controlled to rotate by a drive assembly. The drive assembly includes an L-shaped plate fixedly installed on the surface of one of the mounting plates 2 and a drive motor 4 fixedly installed on the surface of the L-shaped plate. The output shaft of the drive motor 4 passes through the mounting plate 2 and is fixedly connected to one of the rotating shafts 3. A cooling box 5 located directly below the mounting shell 10 is fixedly installed on the upper surface of the base plate 1.

[0032] When the excavator track carburizing bushing needs to be quenched, firstly, by rotating the adjusting wheel at one end of the first threaded rod 14, the slider 15 moves away from the cover 11 along the first threaded rod 14. Since the two ends of the slider 15 pass through the through hole 17 and are fixedly connected to the inner frame wall of the middle rectangular frame 16, and the adjacent rectangular frames 16 are fixed by the connecting rod, the three rectangular frames 16 will move synchronously and separate from the corresponding first rectangular block 12 and second rectangular block 13. At this time, the cover 11 can be opened around the rotating axis, and the carburizing bushing to be quenched can be placed into the mounting shell 10.

[0033] Next, close the cover 11, so that the multiple first rectangular blocks 12 on the cover 11 abut against the multiple second rectangular blocks 13 on the surface of the mounting shell 10. Then, rotate the adjusting wheel of the first threaded rod 14 in the opposite direction to drive the slider 15 to move the three rectangular frames 16 toward the cover 11 until the rectangular frames 16 are simultaneously fitted onto the outside of the corresponding first rectangular blocks 12 and second rectangular blocks 13, thus completing the locking and fixing of the cover 11 and the mounting shell 10.

[0034] Subsequently, the heater 36 on the surface of the mounting shell 10 is activated to heat the carburizing sleeve inside the mounting shell 10. Once the required quenching temperature is reached, the heater 36 is turned off.

[0035] Then, the drive motor 4 is started, and its output shaft passes through the mounting plate 2 and drives one of the rotating shafts 3 to rotate. Since the mounting shell 10 is fixedly installed between the two rotating shafts 3, the mounting shell 10 will rotate with the rotating shaft 3. The carburizing sleeve will tumble inside the mounting shell 10 and be heated evenly. When the heating is completed, the drive motor 4 controls the mounting shell 10 to flip so that the shell cover 11 faces down. Then the drive motor 4 is stopped, and the adjusting wheel of the first threaded rod 14 is rotated to make the rectangular frame 16 separate from the first rectangular block 12 and the second rectangular block 13. The shell cover 11 is opened, and the carburizing sleeve falls into the cooling box 5 located directly below the mounting shell 10 for cooling under the action of gravity.

[0036] Reference Figures 5-6 The upper surface of the cooling box 5 has a cooling groove 6 with a semi-circular longitudinal section. A rotating rod 7 is horizontally rotatably installed in the cooling groove 6. A receiving plate 8 is fixedly sleeved on the rotating rod 7. Multiple through holes 9 are opened on the surface of the receiving plate 8. A sliding groove 18 connected to the cooling groove 6 is opened on one side of the cooling box 5. A collection frame 19 is slidably inserted in the sliding groove 18. The rotating rod 7 is controlled to reciprocate through a transmission assembly. The transmission assembly includes a reciprocating screw 20 horizontally rotatably installed on the surface of one of the mounting plates 2, a sliding plate 21 threaded onto the reciprocating screw 20, and a second threaded rod 22 fixedly connected to the sliding plate 21. Sprockets 23 are fixedly sleeved on both the reciprocating screw 20 and the output shaft of the drive motor 4. Chains 24 are meshed and wound on the two sprockets 23. One end of the rotating rod 7 passes through the cooling box 5 and has a threaded groove 25 that matches the second threaded rod 22. One end of the second threaded rod 22 is threadedly installed in the threaded groove 25.

[0037] When the carburizing sleeve falls into the cooling box 5 located directly below the mounting shell 10 under the action of gravity, it will land on the upper surface of the receiving plate 8. At this time, the carburizing sleeve to be heated is placed into the mounting shell 10 by repeating the above steps. Then, the drive motor 4 and the heater 36 are started. As the output shaft of the drive motor 4 rotates, since the reciprocating screw 20 and the output shaft of the drive motor 4 are both fixedly sleeved with sprockets 23, and the two sprockets 23 are meshed and wound with chains 24, the reciprocating screw 20 will rotate synchronously.

[0038] When the reciprocating screw 20 rotates, the slide plate 21 threaded onto it will reciprocate linearly along the reciprocating screw 20. The slide plate 21 is fixedly connected to the second threaded rod 22. One end of the second threaded rod 22 is threaded into the threaded groove 25 opened in the cooling box 5 at one end of the rotating rod 7. In this way, the reciprocating motion of the slide plate 21 will be transmitted to the rotating rod 7, causing the rotating rod 7 to reciprocate. This will drive the receiving plate 8 fixedly sleeved on the rotating rod 7 to also reciprocate. During the reciprocating rotation of the receiving plate 8, the carburized sleeve falling on it will continuously adjust its position as the receiving plate 8 swings.

[0039] Reference Figure 7 A water tank 26 is fixedly installed on the upper surface of the base plate 1. The water tank 26 is filled with cooling water. A fixing ring 27 is fixedly installed on the surface of one of the mounting plates 2 via an L-shaped connecting rod. An mounting rod 28 is fixedly installed inside the fixing ring 27. One end of the mounting rod 28 has a water groove, and a piston rod 29 is sealed and slidably inserted into the water groove. A water pipe 30 is fixedly installed on one end of the mounting rod 28 via a water outlet pipe 33. One end of the water pipe 30 passes through one of the mounting plates 2. The lower surface of the water pipe 30 is fixedly mounted with... The device is equipped with multiple water distribution pipes 31, the bottom of which extends into the cooling tank 6. The mounting rod 28 is fixedly connected to the water tank 26 via the water inlet pipe 32. Both the water inlet pipe 32 and the water outlet pipe 33 are equipped with one-way valves. The one-way valve in the water outlet pipe 33 is directed from the water tank to the water pipe 30, while the one-way valve in the water inlet pipe 32 is directed from the water tank 26 to the water tank. One end of the piston rod 29 is fixedly mounted with an L-shaped block 34, which is fixedly connected to the slide plate 21 via a fixing rod 35.

[0040] As the receiving plate 8 reciprocates and the carburizing sleeve moves continuously on its upper surface, the piston rod 29 also moves laterally and reciprocally along with the sliding plate 21. When the sliding plate 21 moves away from the mounting rod 28 as the reciprocating screw 20 rotates, the piston rod 29, which is connected to the sliding plate 21 through the fixing rod 35 and the L-shaped block 34, will slide outward synchronously. At this time, the volume of the water tank at one end of the mounting rod 28 increases and the internal air pressure decreases. Since the one-way valve in the water inlet pipe 32 is directed from the water tank 26 to the water tank, the cooling water in the water tank 26 will flow into the water tank through the water inlet pipe 32 under the action of the air pressure difference, thus completing the water suction action.

[0041] When the slide plate 21 moves in the opposite direction and moves closer to the mounting rod 28, the piston rod 29 is pushed to slide into the water tank, the volume of the water tank decreases and the internal air pressure increases. Because the one-way valve in the outlet pipe 33 is directed from the water tank to the water pipe 30, the cooling water in the water tank will be pressurized and enter the water pipe 30 through the outlet pipe 33. Then, the cooling water flows along the water pipe 30 and is evenly transported to the cooling tank 6 through multiple water distribution pipes 31 fixedly installed on its lower surface.

[0042] The cooling water in the cooling tank 6 comes into full contact with the constantly moving carburizing sleeve, which removes the heat from the carburizing sleeve in time, ensuring the efficient cooling process. At the same time, since the reciprocating movement of the piston rod 29 and the reciprocating rotation of the receiving plate 8 are synchronized, the supply of cooling water is perfectly matched with the cooling requirements of the carburizing sleeve, further improving the quenching effect.

[0043] The cooling water entering the cooling tank 6 will pass through multiple through holes 9 into the collection frame 19, thereby collecting the cooling water.

[0044] After cooling is complete, the carburizing sleeve located on the upper surface of the receiving plate 8 is removed. Then, the heated carburizing sleeve located in the mounting shell 10 falls into the cooling tank 6 and lands on top of the receiving plate 8. The next carburizing sleeve to be heated is then placed into the mounting shell 10, and the drive motor 4 is started. This allows the quenching process to form a continuous work cycle, avoiding time waste caused by interruption of a single link. After the previous batch of carburizing sleeves is cooled, there is no need to wait for additional preparation time, and the cooling and heating of the next batch of carburizing sleeves can be quickly started, which greatly shortens the process interval and thus increases the throughput per unit time.

[0045] The drive motor 4 can not only control the rotation of the mounting shell 10, but also drive the reciprocating screw 20 to rotate through the sprocket 23 and chain 24, thereby realizing the rotation of the receiving plate 8 and the pumping of cooling water. The components work together, reducing manual intervention and without generating additional electricity costs, making the quenching process more automated and continuous, which meets the needs of modern production.

[0046] In this utility model, the tooling adopts a rotating connection structure between the mounting shell 10 and the shell cover 11, and is equipped with a locking assembly consisting of a first rectangular block 12, a second rectangular block 13, a first threaded rod 14, a slider 15, and a rectangular frame 16. This replaces the traditional bolt fixing method. The shell cover 11 can be quickly opened, closed, and locked by simply rotating the adjusting wheel, without having to tighten the bolts one by one. This greatly reduces the auxiliary time for placing and removing the carburizing sleeve, reduces the labor intensity of workers, and effectively improves the overall efficiency of the quenching process. Furthermore, by using the drive assembly to control the rotation of the rotating shaft 3, the mounting shell 10 can be rotated as a whole, allowing the heated carburizing sleeve to fall directly into the cooling box 5 below without manual transfer. This design fundamentally eliminates the safety hazard of burns to operators from high-temperature parts and provides reliable safety assurance for the production process.

[0047] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
