Embodiment Construction

[0037] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0038] As a first aspect of the present invention, the present invention provides a processing template for a standard section of a tower crane. like Figure 4-6As shown, the processing template includes: a substrate 71 on which a reference hole 74 used as a processing reference is provided; a first positioning portion 72 and a second positioning portion 76 are also provided on the substrate 71 . Preferably, the first positioning portion 72 and the second positioning portion 76 are arranged orthogonally, so that the processing template can be reliably positioned in two orthogonal directions. Preferably, the first positioning portion 72 is a positioning block, and the positioning block is protrudingly provided on one end surface of the base plate 71...

Abstract

The invention provides a clamp for a standard knot of a tower crane and a processing template thereof. The processing template comprises a substrate, wherein a basic hole for the processing of a connecting hole is formed on the substrate; and a first positioning part and a second positioning part are further arranged on the substrate. According to the invention, the requirements on positions and dimensions of different models of standard knots and the connecting holes thereof can be met by replacing processing templates with different models, and the clamp and the processing template thereof have the characteristics of simplicity in operation and modularity in operation and further have the advantage of convenience for detection, installation, detachment and maintenance.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a jig for a standard section of a tower crane and a processing template thereof. Background technique [0002] Figure 1-3 A schematic structural diagram of a clamp for a standard section of a tower crane in the prior art is shown. The clamp 1 in the prior art includes an L-shaped base 11 , and a first pressing device 12 is respectively arranged on two mutually perpendicular side walls of the base 11 . In addition, the clamp 1 also includes a second pressing device 13, the first end and the second end of the second pressing device 13 are respectively arranged on the two side walls, the second pressing device 13 includes a bracket 131, and the bracket 131 The first end of the bracket 131 is pivotably arranged on one side wall of the base 11 through the shaft 135, the second end of the bracket 131 is detachably connected with the other side wall of the base 11 through the pin ...
