Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled gear hobbing machine tools, in particular to an automatic gear alignment mechanism for a transverse tool rest. Background Art

[0002] Gears are important components in mechanical transmission and play an important role in industrial production. CNC gear hobbing machines are widely used in gear processing machines. They can process spur gears, helical gears, and special tooth shapes of various workpieces, such as spline gears and sprockets.

[0003] When the product is in the trial production or prototype stage, manual gear alignment can be used to complete the positioning of the gear blank, and then the press can be pressed into place. When the product reaches the mass production stage, manual gear alignment can no longer meet the beat requirements. At this time, automatic gear alignment, automatic clamping, and automatic loading and unloading are required to ensure the production beat; at the same time, when the gear is processed in multiple processes such as rough machining → tooth surface quenching → finishing, or when the tool is changed in the middle, the workpiece needs to be repositioned. The traditional positioning method has low positioning efficiency and low positioning accuracy for the tool holder, and a large amount of reserve before finishing, and does not meet the automation requirements.

[0004] In view of this phenomenon, it is urgent to design and develop a transverse automatic gear alignment mechanism that can automatically align the gears. Utility Model Content

[0005] In view of the above existing technical problems, the utility model provides an automatic gear alignment mechanism for a transverse tool holder, which is characterized by comprising a mounting frame, a mounting plate, a first telescopic cylinder, a moving platform, a first slide rail, a fine-tuning assembly, a tool holder, a mounting rod, and a photoelectric switch. The mounting plate is fixed to one end of the mounting frame by screws, the first telescopic cylinder is fixedly mounted on the mounting plate, the telescopic end of the first telescopic cylinder is connected to the moving platform, the moving platform is slidably connected to the first slide rail installed on the mounting frame, a fine-tuning assembly is arranged on the moving platform, a tool holder is installed on the fine-tuning assembly, the other end of the mounting frame is fixed to the mounting rod by screws, and a photoelectric switch is arranged on the upper end of the mounting rod.

[0006] The fine-tuning assembly is composed of a second telescopic cylinder, a second mounting plate, a second moving platform and a second slide rail. The second telescopic cylinder is mounted on the second mounting plate. The second mounting plate is fixedly mounted on the moving platform by screws. The telescopic end of the second telescopic cylinder is connected to the second moving platform. The second moving platform is slidably connected to the second slide rail. The second slide rail is mounted on the moving platform.

[0007] The second movable platform is provided with a tool holder.

[0008] The front ends of the first slide rail and the second slide rail are both provided with limit plates to prevent the moving platform from moving out of the slide rails.

[0009] Specifically, the first telescopic cylinder, the second telescopic cylinder and the photoelectric switch are all electrically connected to an external control cabinet, and the operation of the electronic components is controlled by a controller in the control cabinet.

[0010] Specifically, the photoelectric switch uses an object recognition sensor to recognize the position information of the gear part to be processed.

[0011] Beneficial effects of the utility model:

[0012] The utility model identifies the position information of the gear part to be processed by a photoelectric switch, and sends the position information to a controller in a control cabinet, the controller controls the operation of a first telescopic cylinder and a second telescopic cylinder, the first telescopic cylinder pushes the moving platform forward, moves the tool holder horizontally to the front end, and the second telescopic cylinder in the fine-tuning component starts to push the second moving platform on which the tool holder is installed to move longitudinally to adjust the position of the tool holder, automatically completes the gear alignment action, and reduces the workload of the staff.
