Description

Technical Field

[0001] The utility model relates to the technical field of bar processing, in particular to a full-automatic bar heading machine. Background Art

[0002] The fully automatic bar heading machine is a production equipment specially used for bar processing. It mainly acts on the head of the bar and can continuously process a variety of materials such as stainless steel and carbon steel, thereby improving production efficiency and reducing labor costs to meet various usage needs.

[0003] Common fully automatic bar heading machines are mainly composed of a fixed clamping mechanism and a processing machinery part. The fixed clamping mechanism fixes the bar and then guides it into the processing hole of the processing machinery part for processing. However, before clamping the bar, the processing end of the bar needs to be aligned with the processing hole of the processing machinery part so that the fixed clamping mechanism can push the bar to be inserted into the processing hole. The current existing devices lack an alignment guide mechanism for this and only rely on the position set by the fixed mechanism for operation. Sometimes the processing end of the bar deviates and cannot be accurately introduced into the processing hole for processing. This is very troublesome to handle, delaying processing and production time and affecting processing efficiency.

[0004] Therefore, the existing fully automatic bar heading machine lacks an effective alignment and guiding mechanism, which causes the clamped bar to be unable to be accurately introduced into the processing hole due to position deviation, making it more troublesome to handle, delaying the processing time and seriously affecting the processing efficiency. This problem urgently needs to be solved to improve the use scenario of the fully automatic bar heading machine. Utility Model Content

[0005] In order to overcome the problem that the existing fully automatic bar heading machine lacks an effective alignment and guiding mechanism, resulting in the clamped bar being unable to be accurately introduced into the processing hole due to position deviation, which makes the processing more troublesome, delays the processing time, and seriously affects the processing efficiency.

The external threaded columns push the internal threaded cylinder toward the center, so that the four push blocks push the rod processing workpiece inward at the same time, perform center alignment control on it, and automatically align it with the processing hole path of the processing machinery part. The roller can support the thrust of the rod processing workpiece while allowing the rod processing workpiece to slide through freely and adjust the position, so as to cooperate with the clamping part to keep the position of the rod from deviating, and can accurately introduce it into the processing hole for processing, avoiding unnecessary trouble, shortening the processing time, and improving production efficiency.

[0008] Preferably, the inner side of the chassis is rotatably connected with four rotating shafts parallel to the perimeter lengths, and both ends of each rotating shaft are fixedly connected with a bevel gear 1.

Cylinders are fixedly installed on the left and right ends of the mounting frame, and the movable ends of the two cylinders are respectively fixedly connected to the two clamps.

Cylinder 2 is started to push the mounting frame forward, and the position of the clamp is adjusted to clamp the rear end of the rod workpiece.

[0013] Preferably, two electric slide rails are fixedly installed on the upper end of the frame, and sliders are slidably connected to the two electric slide rails. The upper ends of the sliders are fixedly installed on the bottom of the movable table.

The four external threaded columns simultaneously push the internal threaded cylinder toward the center. The four push blocks simultaneously push the bar workpiece inward. The center alignment is controlled and the workpiece is automatically aligned with the processing hole of the processing machinery. The roller can support the thrust of the bar workpiece while also allowing the bar workpiece to slide through and adjust its position. The clamping part then cooperates with the rod to keep the position of the rod from deviating. The rod can be accurately introduced into the processing hole for processing, avoiding unnecessary trouble, shortening the processing time, and improving production efficiency.

By setting up the chassis, first pass the bar workpiece through it, start the motor to control the rotation and transmission of each rotating shaft, bevel gear 1 and bevel gear 2, and push the four external threaded columns to move the internal threaded barrel toward the center at the same time.

Since the bar workpiece is clamped by the roller, the appropriate length of the bar workpiece can be freely controlled. Finally, start cylinder 2 to push the mounting frame forward and adjust the position of the fixture. Then start the two cylinders 1 to control the fixture to fix the rear end of the bar workpiece. Then further start the electric slide rail. The slider will lead the movable table to move backward, so that the chassis moves backward and docks with the processing machinery part.
