Description

Technical Field

[0001] The invention belongs to the technical field of gear processing, and in particular relates to an automated broaching machine for a transmission gear of an automobile gearbox. Background Art

[0002] A broaching machine is a machine tool that uses a broach as a tool to process through holes, planes, and formed surfaces of workpieces. Broaching can achieve higher dimensional accuracy and less surface roughness, with high productivity, and is suitable for batch mass production. Broaching machines generally include vertical broaching machines and horizontal broaching machines. Broaching machines for automobile transmission gearboxes usually have multiple stations for inspection because the inner hole processing of the gears needs to be inspected during the processing process. During assembly line production, manual inspection cannot guarantee the consistency of inspection. When the gears with processed inner holes are circulated to the broaching machine again, the workpieces are processed twice, resulting in processing deviation and scrapping of the workpieces. When the processed workpieces need to be transferred to the next station, if the unprocessed missing workpieces cannot be effectively detected, they need to be reworked later, which is time-consuming and labor-intensive, and the production is out of touch. In traditional gear feeding devices, several gears use the same feeding channel. Due to the vibration deviation generated during the gear movement process, the end clamp gripping position deviation is caused, causing production difficulties. Summary of the invention

[0033] The feeding device further includes a limit plate 17 disposed at the end of the feeding channel 12 for blocking the workpiece 6 to prevent the workpiece from moving along the roller transmission line 14 and falling off.

[0034] In this embodiment, the roller transmission line 14 is a straight line, and the loading platform 11 is divided into three loading channels 12 .

[0035] In this embodiment, the workpiece is a transmission gear of an automobile gearbox.

[0036] The material blocking device 2 includes a first truss 21 erected above the loading platform 11, and a plurality of material blocking cylinders 22 arranged on the first truss 21 and corresponding to the positions of the loading channel 12. A baffle 23 is connected to the bottom of the material blocking cylinder 22, and the baffle 23 is extended from the material blocking cylinder 22 to between the symmetrical roller transmission lines 14, thereby blocking the movement of the workpiece 6.
