Embodiment Construction

[0036] The following with attached Figure 1 to Figure 6 A modular positioning fixture and a positioning fixture assembly of the present invention will be further described in detail.

[0037] A modular positioning fixture of the present invention, please refer to Figure 1 to Figure 6, comprising a pressure head 11, a first connecting plate 12, a first clamping cylinder 13 and a dust cover 14, one end of the pressure head 11 is hinged to the front end of the extension rod of the first clamping cylinder 13, the pressure The middle part of the head 11 is hinged with the first connecting plate 12 , and the dust cover 14 is arranged around the outer periphery of the protruding rod of the first clamping cylinder 13 . In this way, the protruding rod of the first clamping cylinder 13 stretches out or retracts, driving the ram 11 hinged thereto to move, and the ram 11 moves between the first clamping cylinder 13 and the first connecting plate 12 hinged thereto. Press down or lift u...

Abstract

The invention discloses a modularization positioning fixture and a positioning fixture assembly. The modularization positioning fixture comprises a pressure head, a first connecting plate, a first clamping air cylinder and a dustproof cover; one end of the pressure head is hinged to the front end of an extending rod of the first clamping air cylinder, and the middle portion of the pressure head is hinged to the first connecting plate; and the periphery of the extending rod of the first clamping air cylinder is surrounded by the dustproof cover. The modularization positioning fixture is simple in structure and small in size; moving parts are effectively protected, and the service life of the fixture is prolonged; the modularization positioning fixture is convenient to install, safe in use and high in efficiency; and standard modules are directly called, the machining period is short, the cost is low, and the opening angle of the fixture is large.

Description

technical field [0001] The invention relates to a fixture, in particular to a modular positioning fixture used in automobile manufacturing. [0002] The present invention also relates to a fixture assembly, in particular to a positioning fixture assembly equipped with the above-mentioned modular positioning fixture. Background technique [0003] figure 1 It is a hinged positioning and clamping mechanism commonly used in body manufacturing technology. Its principle is to use the hinged structure to obtain a larger opening angle of the clamp to achieve clamping and positioning of the workpiece. This mechanism mainly consists of seven parts such as positioning block 2, pressing block 1, pressure head 6, connecting plate 4, hinge 3, support base 9, and clamping cylinder 5. When in use, the cylinder 5 retracts to drive the pressure head 6 and Hinge 3 swings and the clamp opens. However, there are some difficult problems in the use of this fixture: [0004] 1. Cylinder 5 is di...
