Embodiment Construction

[0016] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0017] As shown in the figure, the fast turning and tightening mechanism in the embodiment is mainly composed of a mounting seat 1, a pin shaft 2, a handle 3, a turning frame 4, a tightening handle 5, a turning block 6, a tightening shaft 7, a small pin shaft 8, a tightening Parts such as set screw 9, steel ball 10, spring 11, ball head elastic clip 12 are formed.

[0018] Such as Figure 1~Figure 3 As shown, the mounting seat 1 is fixed on the fixture during installation and application, the top of the mounting seat 1 is provided with a mounting groove, and the turning block 6 is hinged on the mounting seat 1 through a small pin shaft 8, and the small pin shaft 8 is installed On the side plates on both sides of the installation groove, the turning block 6 can rotate freely with the small pin shaft 8 as the rotation center, and when the turning block 6 is turn...

Abstract

The invention relates to a rapid overturning and tightly-abutting mechanism. An installation groove is formed in the top of the installation seat. An overturning block is hinged to the installation seat through small hinge shafts installed on side plates on the two edges of the installation groove. The small hinge shafts are installed on the side plates on the two edges of the installation groove. The overturning block can freely rotate with the small hinge shafts as the rotation center. When the overturning block is overturned to a limiting position, the overturning block abuts against the bottom of the installation groove. The overturning block is provided with a pin hole. A tightly-abutting shaft is assembled in the pin hole and can axially and freely move in the pin hole. A screwing-down handle is connected to threads at the left end of the pin hole in a threaded manner. The right end of the screwing-down handle is connected with the tightly-abutting shaft. The right end of the tightly-abutting shaft is used for tightly abutting against a workpiece and locating the workpiece. An overturning frame is hinged to the installation seat through hinge shafts. The hinge shafts are installed on the installation seat. The overturning frame can freely rotate with the hinge shafts as the rotation center. When overturning to the limiting position upwards, the overturning frame presses the overturning frame without exerting force. The rapid overturning and tightly-abutting mechanism is convenient to operate and capable of reliably and tightly abutting against the workpiece, rapidly leaving a workpiece machining area, expanding the machining range and shortening the operation time.

Description

technical field [0001] The invention relates to a fast turning and tightening mechanism, which belongs to the technical field of mechanical processing. Background technique [0002] With the continuous development of the machinery industry and the intensification of industry competition, the requirements for the cost of mechanical parts are also getting higher and higher. When the workpiece is positioned on the machine tool fixture, the part must be close to the positioning element, which requires a clamping mechanism. And when processing, it is hoped that the clamping mechanism avoids the workpiece, so as to expand the machinable range. This requires the clamping mechanism to be able to withdraw from the workpiece area after clamping the workpiece and completing correct positioning. In order to shorten the operation time and improve the processing cycle, it is required that the clamping mechanism can quickly clamp the workpiece and withdraw quickly, but the existing conve...
