Spring type split block structure positioning clamp of free curve surface work pieces

Abstract

The invention provides a spring type split block structure positioning clamp of free curve surface work pieces, which relates to a positioning clamp. The invention provides the spring type split block structure positioning clamp, in particular to the spring type split block structure positioning clamp of free curve surface work pieces, which has the advantages of good realization universality, large installing and clamping dimension, higher positioning precision and convenient use. The spring type split block structure positioning clamp is provided with a base, an upper cover plate, a top needle, a load spring, a left support frame, a right support frame, a top needle clamping frame, a reset spring, a locking screw and a fixed top block, wherein the upper cover plate is arranged on the base, the top needle passes through the load spring to be arranged on the upper cover plate, both the left support frame and the right support frame are fixed on the base, the top needle clamping frame is arranged in the left support frame and the right support frame, the reset spring is arranged between the top needle clamping frame and the right support frame, and the locking screw is arranged on the base. When the locking screw is tightly screwed, the top needle clamping frame can be pushed to move to the right side, and the reset spring is compressed. When the locking screw is unscrewed, the compressed reset spring can push the top needle clamping frame back to the left side. The fixed top block is arranged on the upper cover plate through screws.

Description

technical field [0001] The invention relates to a positioning fixture, in particular to a positioning fixture with a spring type block structure for free-form surface workpieces. Background technique [0002] At present, when processing or measuring free-form surface workpieces, it is necessary to develop and design different positioning fixtures for free-form surface workpieces of different shapes or sizes, which not only increases the cost of free-form surface workpiece processing or measurement, but also increases the processing or measurement cycle. In turn, it affects its overall work efficiency, so it has a certain impact on processing or measurement work. [0003] Chinese patent 02241292.1 discloses an optical element fixture, which is used to carry optical elements, including a first ring body, a second ring body and at least three frames, wherein the outer side of the second ring body is adjacent to the inner side of the first ring body , and the first ring body an...
