Description

Technical Field

[0001] This utility model relates to the technical field of CNC tap grinding machines, specifically to a feeding device for a CNC tap grinding machine. Background Technology

[0002] The CNC tap grinding machine uses a CNC system to achieve multi-axis linkage control. It precisely grinds the front and rear inverted points (bevels) through the coordinated rotation of the X-axis slide and A-axis. It supports programmed operation to ensure processing consistency and efficiency. Some machines are equipped with an automatic feeding system; after batch loading, a single button start completes fully automatic processing.

[0003] Existing tap grinding machines lack a feeding device, requiring manual unloading of workpieces. This repetitive operation leads to high labor intensity and low efficiency. Furthermore, human negligence during this process can easily result in safety accidents. Therefore, to address these issues, we propose a feeding device for CNC tap grinding machines. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a feeding device for a CNC tap grinding machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A feeding device for a CNC tap grinding machine includes a base. A roller seat is connected to the top of the base, and two rollers are mounted through the roller seat. A workpiece rolls between the two rollers. A feeding cylinder base is connected to one side of the roller seat, and a roller motor that works with the rollers is mounted on one side of the feeding cylinder base. A feeding support is connected to the top of the feeding cylinder base, and a feeding cylinder fixing plate is mounted at one end of the feeding support. A two-position feeding cylinder is mounted through the feeding cylinder fixing plate, and a feeding block is fixedly sleeved on the telescopic end of the two-position feeding cylinder. A rotating wheel bracket is connected to the top of one end of the roller seat, and a rotating wheel is movably mounted on the inner side of the rotating wheel bracket via a bearing. A guide plate is connected inside the rotating wheel bracket and below the rotating wheel. A rotating wheel motor that works with the rotating wheel is connected to one side of the rotating wheel bracket, and a hopper is connected to the top of the rotating wheel bracket. A V-groove is formed on the top of the roller seat between the two rollers.

[0007] Preferably, the top material block is located between two rollers and is used in conjunction with the workpiece.

[0008] Preferably, a material-stopping cylinder base is connected to the other side of the rotating wheel bracket, and a material-stopping cylinder is installed through the material-stopping cylinder base. The telescopic end of the material-stopping cylinder is connected to a material-stopping block that cooperates with the workpiece.

[0009] Preferably, a rotary wheel sensor is installed on the other side of the rotary wheel bracket and above the base of the baffle cylinder, and one side of the rotary wheel passes through the rotary wheel bracket and is used in conjunction with the rotary wheel sensor.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes a combination of a hopper, a rotating wheel, a guide plate, a roller seat, a V-groove, a two-position ejector cylinder, and a pressing cylinder. The workpiece inside the hopper is carried out by the rotating wheel through six evenly distributed grooves on its outer circumference. It then falls into the V-groove in the center of the roller seat along with the guide plate. The two-position ejector cylinder receives a signal from the PLC of the CNC tap grinding machine, and its piston rod extends. The workpiece is pushed out by the two-position ejector cylinder along the V-groove onto the rotating roller. The pressing cylinder's pressure roller falls, pressing the workpiece firmly onto the roller. The two-position ejector cylinder completes the ejection operation. Attached Figure Description
