Description

Technical Field

[0001] The invention relates to the technical field of induction quenching, in particular to an induction quenching device used for quenching the inner periphery of pin sleeve parts. Background Art

[0002] The pin sleeve is a mechanical part, usually sleeved on the pin shaft, used to reduce the friction and wear between the pin shaft and other parts. The main functions of the pin sleeve are positioning, shock absorption and buffering. It is often used in high and medium speed shaft transmission with more positive and reverse changes and frequent starting. It puts forward high requirements for the surface hardness and wear resistance of the parts, and puts forward certain requirements for the toughness of the parts. In order to improve the hardness and wear resistance of the pin sleeve, the inner circumference of the pin sleeve is quenched. In the prior art, the workpiece is often carburized and quenched. After the workpiece is cleaned, the workpiece is loaded into the furnace and heated to 900-950 degrees Celsius. The workpiece is kept warm for a sufficient time to allow the active carbon atoms decomposed in the carburizing medium to penetrate into the surface of the steel part, and then the workpiece is immersed in the coolant for quenching to make the performance of the workpiece better and more stable. However, carburizing and quenching have the following disadvantages: a large amount of energy is consumed during the carburizing and quenching process, and pollutants such as waste gas and wastewater are generated, which have a certain impact on the environment. The process of carburizing and quenching is relatively complicated and requires manual operation, which is not convenient for automated production. The salt bath quenching process will generate high temperature, waste gas, etc., and the working environment is poor, which has a certain impact on the health of workers. Summary of the invention

[0056] The present invention has a process debugging stage before formal operation, and the operation process is as follows:

[0057] The workpiece falls onto the loading conveyor chain through the loading box, reaches the unloading end through the loading conveyor chain, and is pushed into the inner circumference loading rotating component by the workpiece unloading pushing component. Before operation, the inner circumference loading rotating component adjusts the overall moving cylinder according to the placement position, so that the receiving tray of the inner circumference loading rotating component is aligned with the unloading port of the loading conveyor chain. After the two receiving trays of the inner circumference loading rotating component are loaded with workpieces, the rotating cylinder of the workpiece receiving component drives the two workpieces to rotate to a position suitable for the truss manipulator to grasp. After the truss manipulator grasps the workpiece, it moves to the turntable component loading station, and the turntable component drives the workpiece to rotate according to the position. The workpiece passes through the loading station, inspection station, quenching station, cleaning station and unloading station. When the workpiece passes the inspection station, the workpiece height is detected by the workpiece height detection component. After arriving at the quenching station, the inner periphery load sensor component heats and quenches the workpiece. After quenching, the workpiece arrives at the cleaning station for cleaning. After cleaning, it arrives at the unloading station. The truss robot grabs the workpiece at the unloading station and transfers it to the inner periphery unloading component. After the workpiece passes through the unloading and dividing slide component, the two workpieces fall into the inner periphery unloading conveyor chain in turn, and enter the subsequent process through the inner periphery unloading conveyor chain to complete the pre-operation inspection.

[0058] The pre-operation inspection mainly checks whether all components are running well and working properly. It can also adjust the quenching process parameters, conveyor chain operation rhythm, etc. After formal operation, only the equipment parameters need to be fine-tuned according to the actual situation.

[0059] The present invention is in formal operation, and its operation process is as follows:

[0060] The workpiece is transported from the loading box to the loading conveyor chain, and then transported to the workpiece unloading port by the loading conveyor chain. The workpiece unloading pushing component pushes the workpiece and drops it into the inner peripheral loading rotating component. After waiting for the two receiving components of the inner peripheral loading rotating component to have workpieces, the inner peripheral loading rotating component rotates to a suitable angle for the truss manipulator to grab, and the truss manipulator component grabs the workpiece and places it at the loading station of the turntable body. After the turntable is started, it drives the workpiece to the inspection station, and the workpiece height detection component on the truss manipulator component detects the height of the workpiece. After the detection is completed, the turntable drives the workpiece to the quenching station, and the inner peripheral load sensor component completes the quenching of the inner peripheral of the workpiece. After the quenching is completed, the turntable drives the workpiece to the cleaning station, and the workpiece is cleaned by the workpiece cleaning component of the truss manipulator component. After the cleaning is completed, the turntable drives the workpiece to the unloading station, and the truss manipulator grabs the workpiece from the unloading position to the unloading and material distribution slide component, and the workpiece rolls from the unloading and material distribution slide component to the inner peripheral unloading conveyor chain, and the workpiece enters the next process from the inner peripheral unloading conveyor chain.
