Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, and in particular to an ultrasonic vibration grinding device. Background Technology

[0002] In the field of advanced manufacturing, ultrasonic vibration grinding equipment demonstrates superior processing performance due to its unique working principle. This device generates a high-frequency electrical signal through an ultrasonic generator, which is then precisely converted into high-frequency mechanical vibration by a transducer. The vibration amplitude is then amplified using an amplitude transformer, and finally transmitted to the grinding tool. Driven by the high-frequency vibration, the grinding tool applies high-frequency impact to the workpiece, working in conjunction with traditional grinding motions to achieve efficient and precise processing results.

[0003] However, there is a critical problem that needs to be solved in the current ultrasonic grinding equipment: when the grinding position of the grinding equipment is in a fixed state, it is difficult to meet the processing requirements of grinding multiple different positions of the part after one clamping, which to some extent limits its processing flexibility and applicability. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an ultrasonic vibration grinding device, which solves the problem that existing ultrasonic grinding devices cannot adapt to grinding multiple positions of parts after a single clamping.

The Y-axis moving platform is mounted on the mounting plate of the X-axis moving platform, and the ultrasonic clamping device is mounted on the mounting plate of the Y-axis moving platform.

[0007] In a preferred embodiment, the ultrasonic clamping device includes a gripper cylinder, a clamping arm disposed above the gripper cylinder, and the grinding device body installed between the clamping arms.

[0008] In a preferred embodiment, the grinding device body includes an ultrasonic generator, an amplitude transformer mounted at the front end of the ultrasonic generator, and a grinding head mounted at the front end of the amplitude transformer.

[0009] In a preferred embodiment, the drive unit includes a drive motor, a small pulley mounted on the output shaft of the drive motor, a large pulley at a corresponding position on one side of the spindle box, and a belt positioned between the small pulley and the large pulley.

[0010] The beneficial effects of this utility model are as follows: the parts are fixed by a chuck, a moving platform is set on one side of the chuck, the grinding device body is installed on the moving platform, the moving platform can drive the grinding device body to move in the X and Y directions, thereby realizing the workpiece clamping and fixing at one time, and then the position of the grinding device body is adjusted to achieve grinding at multiple positions.

Detailed Implementation

[0017] Please see Figure 1-4As shown, the present application provides a technical solution: an ultrasonic vibration grinding device, including a frame 11, a spindle box 12 mounted on the frame 11, a chuck 13 mounted on one side of the spindle box 12 for clamping workpieces, a drive device mounted on the other side of the spindle box 12 for driving the chuck 13 to rotate, and a grinding device body 5 mounted on one side of the chuck 13. A moving platform is also provided on the frame 11, and an ultrasonic clamping device is provided on the moving platform. The grinding device body 5 is mounted on the ultrasonic clamping device.

[0018] The spindle box 3 is a known technology. The gear set of this spindle box 3 can adopt a 3×2 mode, with a module of 5 and a pressure angle of 20°. It can achieve four speeds: 125r / min, 250r / min, 400r / min, and 700r / min through gear meshing switching.

[0019] In a preferred embodiment, the moving platform includes an X-axis moving platform 14 and a Y-axis moving platform 15. Both the X-axis moving platform 14 and the Y-axis moving platform 15 include bearing housings 41, a lead screw 42 disposed between the two bearing housings 41, a servo motor 43 mounted on one side of the bearing housings 41 and connected to the lead screw 42, a slider disposed on the lead screw 42, a mounting plate 45 disposed on the slider, and a guide device 46 disposed below the worktable. The Y-axis moving platform 15 is mounted on the mounting plate 45 of the X-axis moving platform 14, and the ultrasonic clamping device is mounted on the mounting plate 45 of the Y-axis moving platform 15.

[0020] The guiding device 46 is a linear guide rail and slider structure. Through the rotation of the servo motor on the X-axis moving platform 14 and the servo motor on the Y-axis moving platform 15, the uppermost mounting plate 45 can move in two vertical directions, thereby enabling the grinding device body 5 to move in the X and Y directions. This allows adjustment of the grinding device body's position in the length and diameter directions of the workpiece. The servo motor 43 can be a Huichuan MS1H1-55B30CB-A33*R servo motor.

[0021] In a preferred embodiment, the ultrasonic clamping device includes a gripper cylinder 47, gripping arms 48 positioned above the gripper cylinder 47, and the grinding device body 5 mounted between the gripping arms 48. The gripper cylinder 47 is rotatable.

[0022] This embodiment also includes a solenoid valve, which controls the clamping and releasing of the gripper cylinder 47. This allows for positioning and clamping of the grinding device body 5 and removal of the grinding device body 5. When the gripper cylinder 47 is released, it is convenient to replace the grinding device body 5 or the grinding head on the grinding device body 5.

[0023] In a preferred embodiment, the grinding device body 5 includes an ultrasonic generator 31, an amplitude transformer 32 mounted at the front end of the ultrasonic generator 31, and a grinding head 33 mounted at the front end of the amplitude transformer 32.

[0024] The grinding device body 5 is existing technology, and its structure will not be described in more detail.

[0025] In a preferred embodiment, the drive device includes a drive motor 21, a small pulley 22 disposed on the output shaft of the drive motor 21, a large pulley 23 disposed at a corresponding position on one side of the spindle box 12, and a belt disposed between the small pulley 22 and the large pulley 23.

[0026] In this way, the drive motor 21 drives the small pulley 22 to rotate, which in turn drives the large pulley 23 to rotate via the belt, and then transmits the rotation through the spindle box 12, finally driving the chuck 13 to rotate.

[0027] In this way, when a workpiece needs to be ground, the workpiece is clamped on the chuck 13, and then the drive system drives the workpiece to rotate. The moving platform is then controlled to move the grinding device body 5 closer to the workpiece to achieve grinding. By adjusting the moving platform in the X and Y directions, the grinding device body 5 can achieve grinding at multiple positions in the diameter and length directions of the workpiece. Furthermore, the power is transmitted through the ball screw, resulting in high grinding precision.

[0028] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
