Grinding clamp

Abstract

The invention provides a grinding clamp which comprises a base and a sliding rail slidably connected with the base. A sample carrying table is arranged above the sliding rail, one end of the sample carrying table is hinged to the sliding rail, the other end of the sample carrying table is connected with the sliding rail in an inserted mode through a supporting rod, and a lower supporting frame isslidably connected to the sample carrying table. One end of an aluminum alloy sample and one end of a plastic sample are placed on the sample carrying table, the other end of the aluminum alloy sampleand the other end of the plastic sample are placed on the lower supporting frame and extend out of the end of the lower supporting frame, an upper pressing plate is placed on the aluminum alloy sample and the plastic sample, the width of the upper pressing plate, the lower supporting frame and the sample carrying table are greater than that of the aluminum alloy sample and the plastic sample, strip-shaped holes are formed in the two sides of the upper pressing plate in the width direction respectively, loose bolts matched with the upper end face of the sample carrying table are arranged at the ends, close to the supporting rod, of the inner parts of the strip-shaped holes, and fastening bolts matched with the end of the lower supporting frame are arranged in the end, away from the supporting rod, of the inner parts of the strip-shaped holes. The grinding clamp is used for grinding the to-be-welded surfaces of the aluminum alloy sample and the plastic sample.

Description

[0001] This invention is a divisional application for an invention patent with an application date of 2020.02.12, an application number of 202010088544.3, and an invention titled laser welding method of aluminum alloy and plastic, grinding fixture and clamping fixture. technical field [0002] The invention relates to a grinding fixture, which is applied to the laser connection in the form of lap joint and butt joint mixed joint between aluminum alloy and plastic dissimilar materials, and belongs to the technical field of welding and connection. Background technique [0003] With the gradual popularization of automobiles, the problem of environmental pollution has become increasingly serious. Studies have shown that for every 10% reduction in vehicle weight, fuel consumption can be reduced by 6% to 8%, and the improvement of fuel economy means a corresponding reduction in greenhouse gas emissions. In order to meet the requirements of environmental protection and fuel saving,...

Problems solved by technology

At this stage, no scholars have studied the butt joint welding process of aluminum alloy and plastic. This is because the butt joint area of ​​thin plates is small, and the wettability of metal and plastic is very poor, so it is difficult to form a reliable connection.
