[0013] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0014] Please see Figure 1-2The present invention provides a technical solution: a follow-up grinding mechanism, including a base plate 1 disposed on a Y-axis moving component, a follow-up grinding component disposed on the base plate 1, the follow-up grinding component including a tool bar 9 on which a cutting tool 10 is mounted and a grinding spindle 12 on which a grinding head 13 is mounted, two sets of slide rails 2 disposed on the base plate 1, the length direction of the slide rails 2 being the X-axis direction, a slider being slidably disposed on each slide rail 2, several sliders on the same set of slide rails 2 being connected to a mounting plate 6, a first mounting seat 8 and a second mounting seat 11 disposed on the two mounting seats respectively, the cutting tool 10 being mounted on the first mounting seat 8 and the grinding head 13 being mounted on the second mounting seat 11, and a driving component for driving the mounting plate 6 to move is also disposed on the base plate 1; When machining a workpiece, the workpiece is fixed on the worktable and driven to rotate by the spindle. The base plate 1 is mounted on the Y-axis moving assembly (not shown in the figure) to control the follow-up movement of the follow-up grinding assembly in the Y-axis direction. There are two drive assemblies, which drive the grinding spindle 12 or the cutting tool holder 9 to follow up in the X-axis direction respectively. Through dynamic following, deviations can be corrected in real time to improve machining accuracy. At the same time, there is no need to frequently stop for calibration during the machining process, which reduces machining time and improves efficiency. A base 15 and a turntable 16 are provided between the Y-axis moving assembly and the base plate 1. The base 15 is fixed on the moving platform of the Y-axis moving assembly. A rotating shaft is provided inside the base 15, which passes through its top wall and is connected to the turntable 16. The base 15 is fixedly mounted on the turntable 16. Two sets of slide rails 2 are symmetrically arranged along the center of the rotating shaft, and the turning tool bar 9 is opposite to the orientation of the grinding spindle 12. A second motor for driving the rotating shaft to rotate is provided inside the base 15. The turning tool holder 9 and the grinding spindle 12 are oriented in opposite directions to avoid interference between the turning tool 10 and the grinding head 13. The turntable 16 is rotated by the second motor to switch the orientation of the turning tool holder 9 and the grinding spindle 12, so that the turning tool 10 and the grinding head 13 can be switched as needed.

[0015] The drive assembly includes a first motor 3 mounted on a base plate 1 and a lead screw 4 coaxially connected to the first motor 3. Both ends of the lead screw 4 are smooth parts. The smooth part away from the first motor 3 is rotatably connected to a bearing seat 5 mounted on the base plate 1. A movable block is threaded onto the lead screw 4, and the movable block is connected to a mounting plate 6 by screws. The first motor 3 drives the lead screw 4 to rotate, thereby driving the moving block to move in the X-axis direction. The first motor 3 is a servo motor, which is controlled by a servo system and a position follow-up system to realize the follow-up of the cutting tool 10 and the grinding head 13 and ensure machining accuracy.

[0016] The mounting plate 6 has bellows guards 14 at both ends in the X-axis direction. One side of the bellows guard 14 is provided with a mounting piece that is connected to the mounting plate 6, and the other side is provided with a mounting plate 6 that is connected to the base plate 1. The bellows cover 14 can be freely extended and folded. One side of it is connected to the mounting plate 6. It will not hinder the movement of the mounting plate 6, but will also protect the inside of the drive assembly, prevent external objects from adhering to the lead screw 4 or other parts, maintain the continuity of the lead screw 4's rotation, and extend the service life of each part.

[0017] The top surface of the mounting plate 6 is recessed downward to form an arc-shaped groove 7, and the bottom surfaces of the first mounting base 8 and the second mounting base 11 are integrally formed with arc-shaped protrusions corresponding to the arc-shaped groove 7. Both the cutting tool holder 9 and the grinding spindle 12 have circular cross-sections. Designing the bottom of the mounting base as an arc shape can better fix the cutting tool holder 9 or the grinding spindle 12, while also reducing the overall height of the mechanism and reducing space occupation.

[0018] The mounting plate 6 is provided with a positioning key that penetrates the second mounting seat 11, and the cutting tool bar 9 is provided with a mounting groove corresponding to the positioning key. The locating key and the locating groove have the same width. They can be used to position the cutting tool holder 9 to prevent the angle of the cutting tool holder 9 from deviating, which would result in unqualified workpiece machining quality.

[0019] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
