Description

Technical Field

[0001] This utility model relates to the field of CNC gear hobbing machine technology, and in particular to an automatic gear setting structure for a transverse tool post. Background Technology

[0002] Gears, as crucial components in mechanical transmission, play a vital role in industrial production. CNC gear hobbing machines are a widely used type of machine tool in gear processing. They can machine spur gears, helical gears, and various workpieces with special tooth shapes, such as splined gears and sprockets. When a product is in the trial or prototype stage, manual gear setting can be used to position the gear blank, followed by press-fitting. However, when the product reaches the mass production stage, manual gear setting is no longer sufficient to meet the cycle time requirements. Automatic gear setting, clamping, and loading / unloading are then necessary to ensure production cycle time. Furthermore, when gears are processed through multiple steps such as roughing, tooth surface quenching, and finishing, or when changing tools midway, workpiece repositioning is required. Traditional positioning methods suffer from low efficiency and accuracy in tool holder positioning, large allowances before finishing, and do not meet automation requirements.

[0003] The existing patent CN222359394U automatic gear-setting mechanism for a transverse tool holder includes a mounting frame, a mounting plate, a first telescopic cylinder, a moving stage, a first slide rail, a fine-tuning component, a tool holder, a mounting rod, and a photoelectric switch. One end of the mounting frame is fixed to the mounting plate with 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 stage. The moving stage is slidably connected to the first slide rail mounted on the mounting frame. A fine-tuning component is mounted on the moving stage, and the tool holder is mounted on the fine-tuning component. The other end of the mounting frame is fixed to the mounting rod with screws. A photoelectric switch is located at the upper end of the mounting rod. This invention uses the photoelectric switch to identify the position information of the gear part to be processed and sends this position information to the controller in the control cabinet. The controller then controls the operation of the first and second telescopic cylinders to automatically complete the gear-setting action, reducing the workload of the workers.

[0004] However, existing gear-setting mechanisms can only be adjusted in two degrees of freedom: left, right, forward, and backward. When height adjustment is required, it cannot be performed, which fails to meet the needs. To solve the above problems, an automatic gear-setting structure for transverse tool holders is proposed. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an automatic tooth-aligning structure for a transverse tool holder, characterized by comprising a base, a telescopic cylinder, a slide rail, a transverse frame, a moving platform, a slide groove, a transmission rod, a motor, a connecting block, a mounting platform, an electric push rod, a placement plate, a tool holder, and a photoelectric switch. The base is equipped with a telescopic cylinder, a slide rail, a transverse frame, a moving platform, a slide groove, a transmission rod, a motor, a connecting block, a mounting platform, an electric push rod, a placement plate, a tool holder, and a photoelectric switch.

[0006] Furthermore, the telescopic cylinder is controlled by an external controller, the output end of the telescopic cylinder is connected to the transverse frame, the transverse frame is fitted with the slide rail, and the moving platform is fixedly mounted on the transverse frame;

[0007] Furthermore, a transmission rod is installed in the slide groove via a bearing. The transmission rod has threads, and one end of the transmission rod extends out of the slide groove and connects to the output end of the motor. The motor is connected to an external controller. The connecting block is fitted into the slide groove, and the connecting block is connected to the transmission rod via threads. A mounting platform is fixedly installed on the connecting block.

[0008] Furthermore, an electric push rod is fixedly installed on the mounting platform, and a placement plate is installed at the other end of the electric push rod. The electric push rod is connected to an external controller, and a tool holder is installed on the placement plate.

[0009] Furthermore, the photoelectric switch employs an object recognition sensor to identify the position information of the gear part to be processed, and the photoelectric switch is connected to an external controller.

[0010] The beneficial effects of this utility model are:

[0011] This invention controls the extension or retraction of a telescopic cylinder to move the transverse frame left and right on the slide rail, thus achieving the left-right movement of the tool holder. A motor drives a transmission rod to rotate, causing a connecting block to move back and forth within the slide groove of the moving platform, achieving the forward and backward movement of the tool holder. An electric push rod on the mounting platform extends or retracts, moving the placement plate and tool holder up and down. A photoelectric switch detects the position of the tool holder, and the controller performs automatic gear alignment during these three degrees of freedom movements, meeting the needs for height adjustment, reducing the workload of workers, and improving efficiency.
