Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, specifically to a shaft groove cutting device. Background Technology

[0002] In the machining of shaft parts, annular grooves (such as those used for mounting seals or snap rings) and vertical grooves (such as guide grooves used for key connections or positioning) are common structural features. Currently, the machining of annular grooves and vertical grooves usually requires the use of different equipment, which not only increases the purchase and maintenance costs of the equipment but also reduces machining efficiency. Furthermore, during machining, unstable fixing of the shaft can easily lead to insufficient cutting accuracy, thus affecting the quality of the parts. This application proposes a shaft groove cutting device to meet the machining requirements of annular grooves and vertical grooves. Utility Model Content

[0003] In order to overcome the problems in the prior art, this utility model provides a shaft groove cutting device, which solves the problem that the processing of annular grooves and vertical grooves usually requires the use of different equipment, resulting in low processing efficiency and insufficient processing accuracy due to unstable fixing.

[0004] A shaft groove cutting device includes a frame, a support base, a rotary motor, a three-jaw chuck, a Y-axis electric slide rail, a Z-axis electric slide rail, a cutting mechanism, and a control box. The support base is horizontally installed in the middle of the support plate of the frame. A shaft support is rotatably mounted on the support base via bearings. The rotary motor is mounted on the top wall of the frame. The three-jaw chuck is coaxially arranged above the shaft support and is connected to the power output end of the rotary motor via a flange. A set of Y-axis electric slide rails is installed correspondingly on the bottom and top walls of the frame. The axis of the Y-axis electric slide rail is perpendicular to the axis of the shaft support. The Z-axis electric slide rail is vertically installed between the Y-axis electric slide rails. The cutting mechanism is mounted on the Z-axis electric slide rail. The control box is mounted on the frame.

[0005] Furthermore, the cutting mechanism includes a cutting motor, an electric spindle, and a cutting drill bit. The cutting motor is mounted on the slider of the Z-axis electric slide rail, the electric spindle is connected to the power output end of the cutting motor, and the cutting drill bit is mounted on the electric spindle.

[0006] Furthermore, the support base is slidably mounted on the support plate, and a hydraulic lifting platform is installed below the support base.

[0007] Furthermore, a through hole is provided in the middle of the shaft support, a sealing ring is installed on the top of the shaft support, and the suction end of the negative pressure pipe is rotatably installed at the bottom of the shaft support through a bearing. The output end of the negative pressure pipe is connected to a vacuum pump.

[0008] Furthermore, the cutting motor is equipped with a Y-axis distance measuring sensor and a Z-axis distance measuring sensor, which are connected to a PLC controller in the control box. The PLC controller is connected to the rotary motor, the Y-axis electric slide rail, the Z-axis electric slide rail, the cutting motor, the hydraulic lifting platform, and the vacuum pump, respectively.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention features a dual-fixing structure combining a three-jaw chuck and a negative pressure adsorption device. The upper and lower fixing method enhances the stability of the shaft during processing, preventing insufficient machining accuracy due to vibration or loosening. Simultaneously, the multi-dimensional slide rail system of the cutting mechanism enables precise vertical (Z-axis) and horizontal (Y-axis) movement of the cutting head. Combined with servo motor-controlled rotation, a single device can complete the machining of annular and vertical grooves, simplifying the process. Furthermore, the drill bit pre-drills a guide hole for positioning before cutting, further improving the accuracy of groove machining. This device not only improves processing efficiency and meets the machining needs of shaft parts of various sizes and specifications, but also solves the problems of low cutting efficiency and unstable fixing caused by the diversification of equipment in existing technologies.

A shaft support 21 is rotatably mounted on the support base 2 via bearings to limit the installation of the shaft. The rotary motor 3 is mounted on the top wall of the frame 1 to provide power for the rotation of the shaft. The three-jaw chuck 4 is coaxially arranged above the shaft support 21 to limit and fix the upper end of the shaft. The three-jaw chuck 4 is connected via a method... The disc is connected to the power output end of the rotary motor 3. The rotary motor 3 provides power to make the shaft rotate for easy cutting of the annular groove. A set of Y-axis electric slide rails 5 are installed on the bottom and top walls of the frame 1 to allow the cutting mechanism 7 to move back and forth. The axis of the Y-axis electric slide rail 5 is perpendicular to the axis of the shaft support 21 to ensure that the cutting mechanism 7 accurately feeds the blade to the shaft. The Z-axis electric slide rail 6 is vertically installed between the Y-axis electric slide rails 5. The cutting mechanism 7 is installed on the Z-axis electric slide rail 6 and can move up and down.

[0025] Install the shaft to be processed on the shaft support 21 of the support base 2, start the hydraulic lifting platform 9 to fix the shaft to the three-jaw chuck 4 and keep the center line of the shaft aligned with the center line of the main shaft of the device. Clamp the upper end of the shaft with the three-jaw chuck 4, start the vacuum pump 23 to fix the lower end of the shaft on the shaft support 21, and at the same time check whether the rotating motor 3 works smoothly to ensure that the shaft remains coaxial and fixed when rotating.

Move the cutting mechanism 7 to the processing starting position via the Y-axis electric slide rail 5 and Z-axis electric slide rail 6, start the cutting motor 71, and drive the cutting drill bit 73 to drill a guide hole on the surface of the shaft for positioning. After completing the guide hole, the cutting operation of the corresponding groove type begins.
