Description

Technical Field

[0001] The utility model relates to the technical field of broaching machines, and particularly relates to a broach chip cleaning mechanism. Background Technique

[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. The broach used is a high-precision and high-efficiency multi-tooth tool. According to the different surfaces processed by the tool positions, it can be divided into two categories: internal broaches and external broaches. Internal broaches are used to process various internal surfaces, such as round hole broaches, square hole broaches, spline broaches, etc.; external broaches are used to process various external surfaces, such as plane broaches, tooth groove broaches, right-angle broaches, etc.

[0003] Common broaching machines are divided into horizontal broaching machines and vertical broaching machines. Among them, a horizontal broaching machine usually sets a workpiece holder in the middle of the bed body to clamp the workpiece, and sets linear modules on both sides to control the movement of the broach. The broach moves from one end side of the workpiece to the other end side of the workpiece. During the operation of the broach, it is also necessary to clean the chips through a cleaning brush and cleaning liquid to ensure the stability of the continuous operation of the broach. For example, the Chinese utility model patent with the patent publication number CN215698425U discloses a self-cleaning device for a broach on a broaching machine. This device drives the cleaning brush to swing left and right through a swinging mechanism to sweep away the metal chips attached to the cutting edge of the broach, and is flushed through a flushing mechanism to ensure the cleaning effect.

[0004] When the above-mentioned self-cleaning device for a broach on a broaching machine is actually operated, since the cleaning brush is arranged above the broach and only swings back and forth, this cleaning method can only clean broaches with the cutting edge facing up, such as tooth groove broaches and plane broaches, and the cleaning effect on broaches with the cutting edge covering the entire tool body, such as round hole broaches and square hole broaches, is relatively poor. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the above technical deficiencies, and propose a broach chip cleaning mechanism to solve the technical problem that the cleaning effect on some broaches in the prior art is relatively poor.

[0006] To achieve the above technical purpose, the utility model adopts the following technical solutions:

Several strip brushes are all located inside the rotating cylinder and are distributed in a ring shape. The driving member is located above the rotating cylinder and is used to drive the rotating cylinder to rotate. The gas-liquid pipe is arranged around the outside of the central part of the rotating cylinder and is used to spray cleaning liquid into the rotating cylinder. The connecting cylinders are oppositely arranged at both ends of the rotating cylinder and are used to discharge cleaning dirt downward.

[0008] In some embodiments, both opposite ends of the rotating cylinder are trumpet-shaped.

[0009] In some embodiments, a plurality of strip-shaped mounting grooves are evenly formed in the inner wall of the rotating cylinder, and a plurality of strip brushes are respectively arranged in the plurality of mounting grooves.

The motor is located at the top of the rotating cylinder and fixedly connected to the connecting cylinder. The gear is fixedly installed on the output shaft of the motor, and the gear meshes with the toothed ring.

[0011] In some embodiments, an annular cavity is clamped in the middle of the rotating cylinder. A plurality of spray holes are formed in the annular cavity inward. The gas-liquid pipe is rotatably sleeved outside the rotating cylinder. The inner wall of the gas-liquid pipe is communicated with the annular cavity, and both ends of the gas-liquid pipe are communicated with a liquid storage device.

[0012] In some embodiments, the connecting cylinder is in a right-angled shape. One ends of the two connecting cylinders are respectively communicated with both ends of the rotating cylinder. Circular through holes are formed in both outer ends of the two connecting cylinders. The two circular through holes are coaxially arranged with the rotating cylinder and communicated with each other. The other ends of the two connecting cylinders are both distributed downward and fixedly connected to the same filter chamber. The same mounting frame is fixedly connected to the outside of the two connecting cylinders.
