Description

Technical Field

[0001] This application relates to the technical field of helical gear machining, and in particular to an integrated device for quenching and cooling helical gears. Background Technology

[0002] Helical gears are a type of cylindrical gear where the teeth are not parallel to the gear's axis, but rather at a specific angle. This inclined tooth design gives them a significant advantage over the most common spur gears in transmission.

[0003] When quenching helical gears, heating is required to ensure their hardness and wear resistance. The current method involves the operator placing the helical gear on a mounting base, and a high-frequency quenching assembly quenching the gear. After quenching, a lifting plate immerses the mounting base and gear in cooling water. Once cooled, the lifting plate raises the mounting base and gear, allowing the operator to replace the gear on the mounting base. This process is time-consuming and affects the overall efficiency of quenching and cooling the helical gear, requiring improvement. Utility Model Content

[0004] The purpose of this application is to provide an integrated quenching and cooling device for helical gears, in order to improve the efficiency of quenching and cooling of the entire helical gear.

[0005] The integrated quenching and cooling device for helical gears provided in this application adopts the following technical solution: it includes a quenching table, which is connected to at least two cooling boxes filled with cooling water. A quenching component is slidably connected to the quenching table, and a driving component is connected to the quenching table. The driving component is used to move the quenching component from one of the cooling boxes to the other cooling box. The quenching table is connected to a positioning and placement structure and a clamping and transporting component. The positioning and placement structure is used to place the helical gear, and the clamping and transporting component is used to move the helical gear at the positioning and placement structure to the quenching component.

[0006] By adopting the above technical solution, the helical gear is placed at the positioning structure, which positions the helical gear precisely in the corresponding location. This facilitates the clamping and transporting component to move the helical gear from the positioning structure to the quenching component, with the helical gear positioned above one of the cooling boxes. The quenching component quenches the helical gear. After quenching, the clamping and transporting component releases the helical gear, allowing it to fall into the cooling box for cooling. The clamping and transporting component then retrieves a new helical gear from the positioning structure. During this process, the drive component moves the quenching component above another cooling box, where the clamping and transporting component moves the new helical gear to the quenching component for quenching. Simultaneously, the operator retrieves the helical gear from the first cooling box. The quenching component does not need to wait for the helical gear to cool completely before quenching, saving time and improving the overall efficiency of quenching and cooling the helical gear.

[0007] Optionally, the positioning and placement structure includes a longitudinal plate and two transverse plates, the longitudinal plate and the two transverse plates forming a positioning groove, the positioning groove being used for placing the helical gear.

[0008] By adopting the above technical solution, the helical gear is placed in the positioning groove, and the helical gear abuts against the longitudinal plate and the two transverse plates at the same time. The longitudinal plate and the two transverse plates play a positioning role in the installation of the helical gear, so that the helical gear is accurately placed in the corresponding position.

[0009] Optionally, the quenching table is connected to a storage column, the storage column is provided with a storage cavity, the storage cavity is provided along the height direction of the storage column, the bottom of the storage column is provided with a discharge groove, and the quenching table is connected to a sequential pushing assembly, the sequential pushing assembly is used to drive the helical gear in the storage cavity to pass through the discharge groove sequentially and move to the positioning groove.

[0010] By adopting the above technical solution, the operator only needs to stack multiple helical gears in the storage cavity, and the pusher component can drive the helical gears in the storage cavity to move into the positioning slot in sequence. This eliminates the step of manually placing the helical gears in sequence, reduces the workload of the operator, and is more convenient.

[0011] Optionally, the sequential pushing assembly includes a pusher plate slidably connected to the quenching table and a first driving member for driving the pusher plate to slide towards or away from the positioning groove. The first driving member is connected to the quenching table, and the storage column is provided with a clearance groove communicating with the storage cavity. The clearance groove is used for the pusher plate to pass through.

[0012] By adopting the above technical solution, the first driving component drives the push plate to slide towards the positioning groove. The push plate abuts against the lowest helical gear and drives the helical gear to move towards the positioning groove. At the same time, the push plate and the helical gear above the push plate move towards the positioning groove. The first driving component drives the push plate to slide away from the positioning groove until the push plate is misaligned with the helical gear in the storage cavity. The helical gear in the storage cavity falls due to gravity, and the gear at the bottom corresponds to the push plate. The push plate can then push the helical gear into the positioning groove. By repeating the above steps, the automatic feeding of helical gears can be achieved.

[0013] Optionally, the storage column is provided with a relief groove communicating with the storage cavity, and the relief groove is provided along the length direction of the storage column.

[0014] By adopting the above technical solution, when the operator places the helical gear into the storage cavity, the operator's hand can enter the storage cavity through the clearance groove. The clearance groove provides clearance space for the installation of the helical gear, thereby improving the efficiency of helical gear placement.

[0015] Optionally, the clamping and transport assembly includes a sliding plate slidably connected to the quenching table, a drive structure for driving the sliding plate to slide towards or away from the positioning groove, a carrier plate slidably connected to the sliding plate, a second drive member for driving the carrier plate to slide vertically, and a clamping structure connected to the carrier plate. The drive structure is connected to the quenching table, and the second drive member is connected to the sliding plate.

[0016] By adopting the above technical solution, the driving structure drives the sliding plate to slide towards the relief groove. The carrier plate and clamping structure move with the sliding plate until the clamping structure corresponds to the positioning groove. The second driving component drives the carrier plate to descend, so that the clamping structure moves to the relief groove and clamps the helical gear. The second driving component drives the carrier plate to rise, and the driving structure drives the sliding plate to slide away from the relief groove, so that the helical gear clamped by the clamping structure corresponds to the quenching component. The second driving component drives the carrier plate to descend, so that the helical gear moves to the quenching component and the quenching component quenches the helical gear, thereby realizing automated feeding and quenching of helical gears, saving manpower and being more convenient.

[0017] Optionally, the clamping structure includes two clamping plates slidably connected to the carrier plate and a third driving member for driving the two clamping plates to slide toward each other or away from each other, the third driving member being connected to the carrier plate.

[0018] By adopting the above technical solution, when the two clamping plates are located on the inner ring of the helical gear, the third driving component drives the two clamping plates to slide away from each other, and the clamping plates abut against the inner ring of the helical gear and tension the helical gear. After the helical gear is quenched, the third driving component drives the two clamping plates to slide towards each other, the clamping plates release the helical gear, and the quenched helical gear falls into the cooling box under the influence of gravity, realizing the automatic clamping and automatic release of the helical gear.

[0019] Optionally, both of the two clamping plates have an outer arc surface on opposite sides.

[0020] By adopting the above technical solution, the clamping plate with an outer arc surface increases the contact area with the helical gear, increases the friction, and thus improves the clamping effect of the clamping plate.

[0021] Optionally, each of the cooling boxes is slidably connected to a lifting plate, and the cooling box is connected to a lifting assembly. The lifting assembly is used to drive the lifting plate to rise and fall, and the lifting plate is provided with a number of water filter holes.

[0022] By adopting the above technical solution, the lifting plate serves to support the quenched helical gear. The lifting assembly drives the lifting plate to descend, immersing the helical gear on it in cooling water. Once the helical gear has cooled completely, the lifting assembly drives the lifting plate to rise, removing the helical gear from the cooling water for easy access by the operator. When the lifting plate rises, the cooling water on it returns to the cooling tank through the filter holes, preventing cooling water from overflowing.

[0023] Optionally, the lifting plate is provided with a retrieval hole, the diameter of which is larger than the inner diameter of the helical gear and smaller than the outer diameter of the helical gear.

[0024] By adopting the above technical solution, the operator's hand can be inserted into the retrieval hole, making it easy for the operator to access the bottom of the helical gear and retrieve it.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The quenching component quenches the helical gear. After the helical gear is quenched, the clamping and transporting component releases the helical gear, allowing it to fall into the cooling box for cooling. The clamping and transporting component then retrieves a new helical gear from the positioning and placement structure. During this process, the driving component drives the quenching component to move, causing it to move above another cooling box. The clamping and transporting component then moves the new helical gear to the quenching component for quenching. Simultaneously, the operator retrieves the helical gear from the first cooling box. The quenching component does not need to wait for the helical gear to cool completely before quenching, saving time and thus improving the overall efficiency of quenching and cooling the helical gear.

[0026] 2. The lifting plate serves to support the quenched helical gear. The lifting assembly drives the lifting plate to descend, immersing the helical gear on the lifting plate in the cooling water. After the helical gear has cooled down, the lifting assembly drives the lifting plate to rise, allowing the helical gear to be removed from the cooling water and easily retrieved by the operator.
