[0002] The springless circular blade lock is a common lock, which is often used on padlocks, safes, filing cabinets, mailboxes and other items. It is also used in some industrial equipment, machine room facilities and other related places with special requirements. At present, the automatic gear milling machine for springless circular blade locks that is common in the existing technology can usually only perform processing operations on one gear at a time when it is put into use. In view of the fact that each gear must go through multiple links such as clamping, gear milling, angle switching and disassembly during the processing process, and these processes are carried out one by one in sequence and cannot be superimposed on each other. Therefore, when it is necessary to process the gears in batches, it takes a long time, and a large number of devices are required to drive them.

[0015] A processing method of an automatic gear milling machine applied to a springless circular blade key comprises the following steps:

[0016] S1. When performing gear milling, the workpiece is placed on the pallet, and the position of the workpiece is locked by the nut and the stud thread transmission, and then the support shaft is driven to rotate by the first motor. Under the action of the first belt transmission structure, the two support shafts rotate synchronously, and the support shaft drives the support plate to rotate, so that the positions of multiple pallets are switched;

[0017] S2. After switching, the workpiece is located at the position of the milling saw, and then the second motor drives the roller to rotate. The roller controls the driving rod to reciprocate through the arc groove, so that the driving rod drives the support frame to reciprocate, and the support frame drives the milling gear assembly to reciprocate. During the rotation of the roller, the roller also drives the polygonal shaft to rotate through the second belt transmission structure, and the polygonal shaft drives the polygonal cylinder and the first bevel gear to rotate.

[0019] S4. When the tooth milling saw completes the tooth milling of the workpiece on the right, the support frame moves to the left. When the roller is away from the slope of the inclined plate, the spring drives the first piston rod to reset. At this time, the left-side latch locks the second gear. At the same time, the switching drive assembly meshes with the second gear on the right and adjusts the angle. Then, the tooth milling saw is used to perform tooth milling. In this way, the circumferential surface tooth milling of the workpiece is completed in a cycle. After processing, the support plate is rotated to switch to the next workpiece for processing.

[0020] Compared with the prior art, the present invention provides an automatic gear milling machine and a processing method thereof for a springless circular blade key, which has at least one of the following beneficial effects:

[0021] 1. The automatic gear milling machine and processing method for springless circular blade keys drive two clamping components to rotate through an active driving component, so that the support plate can switch the position of the tray, thereby performing automatic feeding operations. Secondly, the gear milling component is driven to reciprocate by an adjusting component, so that the gear milling component can switch the gear milling operations on the workpieces on both sides through reciprocating motion. In addition, during the gear milling process, the turntable remains fixed, which can provide time for fixing the workpiece and achieve the purpose of loading, thereby reducing the operation time and meeting the needs of efficient processing.

[0022] 2. The automatic gear milling machine and processing method for springless circular blade keys drive the roller to rotate through the second motor, and the roller drives the driving rod to reciprocate through the arc groove, so that the support frame drives the milling gear assembly and the bracket to reciprocate, and the bracket drives the vertical cylinder to reciprocate. When the roller moves to the inclined surface of the inclined plate, the inclined plate pushes the first piston rod through the roller, and the second piston rod and the adjustment plate are driven to move by hydraulic pressure. At this time, the third motor drives the first gear and the second gear to mesh and transmit, so that the rotating shaft drives the tray and the workpiece to rotate an angle. Subsequently, the milling gear assembly contacts the workpiece at another position, and the gear milling operation can be performed at this time. When the support frame turns to the other side, the roller is away from the inclined surface of the inclined plate. At this time, the spring drives the first piston rod to reset, so that the switching drive assembly can be transmitted with the second gear on the other side, so that the workpiece at another position rotates an angle, so that the milling gear assembly switches the milling gear between the workpieces, and the gear milling process can also switch the workpiece angle, thereby improving the processing efficiency, reducing equipment investment, and reducing the use cost.

[0023] 3. The automatic gear milling machine and processing method for springless circular blade keys drive the clamping component to rotate through the active driving component to achieve the purpose of feeding processing, and the feeding processing can realize feeding and avoid processing idle times. Secondly, the adjusting component drives the milling component to reciprocate, and at the same time, the adjusting component and the transmission component are transmitted, so that the transmission component and the milling component can realize switching milling of the workpieces on both sides, and in the process of switching milling, the roller cooperates with the inclined plate, so that the hydraulic component can adjust the position of the switching drive component, so that the clamping tooth and the second gear are switched and locked, thereby maintaining the stability of the milling tooth and improving the milling tooth yield. At the same time, the switching drive component can realize the steering of the workpiece through the second gear drive shaft, so that the milling tooth and the workpiece angle steering are staggered and do not affect each other, meet the needs of automated processing, and improve the automation effect, thereby greatly improving the processing efficiency.
