Problems solved by technology

[0002] A link in the high-speed grinding method is shown in Figure 1. The indenter 1 is powered by a pneumatic system, moves downward at a certain speed, and presses against the gland 3 on the workpiece 2 until the workpiece 2 is pressed. The moment the gland 3 contacts, a strong impact is produced on the gland 3, which seriously affects the machining accuracy and sometimes causes damage to the workpiece
To solve this problem, one way is to reduce the flow rate of the gas supplied by the pneumatic system and reduce the moving speed of the pressure head 1, which will reduce the production efficiency

Embodiment Construction

[0008] The specific embodiment of the device of the present invention is shown in Fig. 3. An equal-diameter through hole is opened at the axial center of the pressure head 1, which is in the shape of a circular tube. As a compressed air working pipeline 8, its diameter is between 1 and 10 mm. The pressure head 1 is a part of a rotary body, and the exhaust port of the pipeline 8 is located at the lower end of the pressure head 1 . The exhaust port is used as the end of the pipeline 8, and its shape is also a circular tube. Also can be trumpet shape, see exhaust port 10 shown in Figure 5. Also can be conical shape, see exhaust port 11 shown in Figure 6. It can also be a step hole shape, see the exhaust port 12 shown in FIG. 7 . The diameter of the circle formed by the spherical intersection of the exhaust port 10, 11, 12 and the surface of the pressure head 1 is 2-15 mm.

[0009] The specific embodiment of the method of the present invention is realized in this way, as shown ...

Abstract

A mechanism and method for buffering the impact of the press head of high-speed grinding machine features that a through hole is made along the central axis of press head and connected to a compressed air source, and when the press head is moving close to the arc hold on press cover, the sprayed compressed air can form an air cushion to buffer its impact.

Description

technical field [0001] The invention is an improvement to the existing high-speed grinding method and device, and belongs to the technical field of precision and ultra-precision machining. Background technique [0002] A link in the high-speed grinding method is shown in Figure 1. The indenter 1 is powered by a pneumatic system, moves downward at a certain speed, and presses against the gland 3 on the workpiece 2 until the workpiece 2 is pressed. The moment the gland 3 contacts, a strong impact is generated on the gland 3, which seriously affects the machining accuracy and sometimes causes damage to the workpiece. In order to solve this problem, one way is to reduce the flow rate of the gas supplied by the pneumatic system and reduce the moving speed of the pressure head 1, which will reduce the production efficiency. In fact, the root cause of the above problems is that the moving speed of the indenter 1 is a constant. In order to reduce the impact of the indenter 1 on the...
