Problems solved by technology

Since abrasive water jet polishing mainly removes material through shearing and grinding, the angle selected for this process is generally relatively small. However, many abrasive water jet processing equipment currently on the market are three-axis, and many five-axis processing The deflection angle of the device is also limited

Embodiment 1

[0035] The abrasive water jet polishing experimental platform proposed in this example is applied in the abrasive water jet polishing process. The surface of the workpiece is ground and removed through the high-speed collision and shearing action of abrasive particles, and the polishing process of quantitatively correcting the surface roughness of the workpiece by controlling the process parameters such as the pressure, angle and injection time of the polishing liquid injection. In this embodiment, in order to meet the angle adjustment in the process to improve the quality of the polishing process, refer to figure 1 As shown in , the experimental platform includes a base 100 , a clamping unit 200 and an adjusting unit 300 . Specifically, the base 100 is used as a supporting base, and is used for the positioning and installation of the experimental platform on the grid-shaped platform. The clamping unit 200 and the base 100 are connected by the shaft 101 to form an angle, and t...

Embodiment 2

[0038] In order to realize the adjustment of the angle between the base 100 and the clamping unit 200 through the expansion and contraction of the adjustment unit 300 , that is, to adjust and lock the injection angle of the clamping unit 200 in the process, so as to improve the process quality. This embodiment differs from the first embodiment in that: the adjustment unit 300 further includes a guide assembly 301 and a positioning assembly 302 . Specifically, the experimental platform includes a base 100 , a clamping unit 200 and an adjusting unit 300 . Specifically, the base 100 is used as a supporting base, and is used for the positioning and installation of the experimental platform on the grid-shaped platform. The clamping unit 200 and the base 100 form an angle after being rotationally connected by the shaft 101, and the clamping unit The rotation of 200 around the axis 101 changes the size of the included angle. It should be noted that the axis 101 is arranged on the out...

Embodiment 3

[0041] In the above-mentioned second embodiment, since the locking block 302b cannot move downward after sliding upward when stretched, there is a problem that the angle cannot be decreased after the angle is continuously increased, and the flexibility of adjusting the angle is not satisfied. In order to solve this problem in the embodiment, refer again to Figure 4~5As shown, the difference from the second embodiment is that the guide assembly 301 further includes a reset guide groove 301c, a separation guide part 301d and a merge guide part 301e. Specifically, the experimental platform includes a base 100 , a clamping unit 200 and an adjusting unit 300 . Specifically, the base 100 is used as a supporting base, and is used for the positioning and installation of the experimental platform on the grid-shaped platform. The clamping unit 200 and the base 100 form an angle after being rotationally connected by the shaft 101, and the clamping unit The rotation of 200 around the ax...

Abstract

The invention discloses an abrasive water jet polishing experimental platform. The platform comprises a base for positioning and mounting an experimental platform on a grid-like platform, a clamping unit connected to the base through shaft rotation to form an included angle and changing the included angle through rotation of the clamping unit around the shaft, and an adjustment unit arranged in the inner side of the included angle, having two ends respectively connected to the base and the clamping unit and adjusting and locking the included angle. The experimental platform realizes adjustmentat different angles and solves the problem of an abrasive water jet processor in angle adjustment. The platform can clamp various types of plates and cylindrical workpieces and facilitate polishing experiments.

Description

technical field [0001] The invention relates to the technical field of abrasive water jet processing, in particular to an experimental platform for abrasive water jet polishing. Background technique [0002] Abrasive water jet processing technology is a special cold processing technology that has emerged and developed rapidly in recent years. Compared with traditional mechanical processing methods, this technology has unique advantages such as high processing flexibility, no heat-affected zone, high processing quality, and environmental protection. properties, are more and more widely used in various fields. [0003] Abrasive water jet polishing is a mixture mixed with fine abrasive particles sprayed out at high speed through the nozzle to act on the surface of the workpiece. Through the high-speed collision and shearing of the abrasive particles, the material is removed by grinding. By controlling the pressure of the jet injection, the flow rate of the abrasive, The polish...
