Embodiment Construction

[0015] Use two matching φ12 positioning pins 8 and two M10X30 screws 9 to assemble the left and right screw brackets 2 to the left and right end faces 101 and 102 of the linear adjustment support 1, thereby ensuring the structure. Stable and rigid.

[0016] Frame the screw mandrel 4 in the notch of the left and right screw mandrel brackets 2, and lock the two sides of the notch with a nut 7 of M12 respectively.

[0017] Put the two sections of guide rails 303, 304 of the linear adjustment support 3 into the inverted T-shaped guide chute 103 of the linear adjustment support 1, so as to ensure that the linear adjustment support 3 can be in the inverted T-shaped guide chute 103, along X-X Directions slide freely.

[0018] Since the width tolerance of the guide chute 103 is +0.015 mm, and the tolerance of the guide slide rail matched with it is -0.01 mm, the movement of the linear adjustment support 3 in the Y-Y direction can be well constrained.

[0019] Because the notch 305 o...

Abstract

The invention relates to a linear regulating assembly applied to a combined clamp in machinery industry. The linear regulating assembly comprises a linear regulating support saddle, a linear regulating support, a left lead screw support, a right lead screw support, a lead screw, a rectangular nut, a socket cap inner hexagon bolt and the like. When the linear regulating assembly is used for adjusting a position, the linear length dimension is measured by a block gauge or a dial indicator; after the adjustment of the dimension is ended, hexagon nuts on the two sides of the linear regulating support on the lead screw are used for locking; simultaneously, the bolt is matched with the rectangular nut for locking in the Z direction so as to achieve the purposes of linear adjustment and rigid positioning; and furthermore, a positioning pin hole and a threaded hole are formed on the upper end surface of the linear regulating support so as to form rigid connection with other support pieces, and the positioning pin hole and an unthreaded hole, which have the effects of enabling the linear regulating assembly to do jump translation and be locked in the Y-Y direction, are formed on the bottom surface of the linear regulating support saddle.

Description

Technical field: [0001] The invention relates to a linear adjustment assembly used for combined fixtures in the machinery industry, and belongs to the technical field of combined fixture device structures for auxiliary machining. Background technique: [0002] In the modern mechanical processing industry, in the process of clamping parts, it is necessary to perform rigid positioning and fine linear adjustment on the part, while the groove combination fixture can perform fine linear adjustment, but cannot achieve rigid positioning. , The hole system combination fixture can perform rigid positioning, but cannot achieve fine linear adjustment. [0003] The invention provides a combined fixture linear adjustment assembly capable of both rigid positioning and fine linear adjustment during the part clamping process. Invention content: [0004] A linear adjustment component of a combined fixture, characterized in that it includes: a linear adjustment support, a left and right sc...
