Embodiment 1

[0033] The technical solution adopted in this embodiment is as follows figure 1 , figure 2 as well as Figure 7-12 As shown, a multi-point synchronous retracting tooling includes a two-way threaded shaft 1, a connecting piece 2, and a connecting plate 3 movably arranged along the axis of the two-way threaded shaft 1. The triangular threads on both sides of the two-way threaded shaft 1 (triangular threads are mainly It is used for fastening. If the tension force is not high, rectangular or trapezoidal transmission threads can be used.) The direction of rotation is opposite, the connecting disk 3 is a regular dodecagon, and the center of the connecting disk 3 is provided with a bidirectional threaded shaft. 1 Internally threaded holes with matching threads, connecting grooves 31 are provided at equal intervals along the circumference of the connecting plate 3, and connecting rods 32 are arranged in the connecting grooves 31. The two connecting plates 3 are a group and the two are ...

Abstract

The invention relates to a multi-point synchronous take-up and pay-off tool. The multi-point synchronous take-up and pay-off tool comprises a two-way threaded shaft, connecting pieces and connecting discs movably arranged in the axial direction of the two-way threaded shaft. The rotating directions of threads on the two sides of the two-way threaded shaft are opposite, two connecting discs are arranged in each group, the two connecting discs are connected to the threads on the two sides of the two-way threaded shaft through thread pairs correspondingly, and the two connecting discs are connected through the connecting pieces, supporting parts and the connecting pieces, wherein the connecting pieces, the supporting parts and the connecting pieces are sequentially arranged, and the joints ofthe connecting pieces, the connecting discs and the supporting parts are in hinge joint. The multi-point synchronous take-up and pay-off tool in the technical scheme is simple in structure and convenient to use, and the problems that in an existing supporting manner, supporting force is insufficient, adjusting is difficult, the stability is poor, and the dimensional precision is not high can be effectively solved.

Description

Technical field [0001] The invention relates to the technical field of connection and fastening, in particular to a multi-point synchronous retracting and releasing tooling. Background technique [0002] During the cutting process of the pipe, due to the characteristics of the pipe itself and the large accumulation of cutting heat, the axial expansion and the gravitational action of the inner wall during the cutting process will cause the central part to be inaccurate. The existing solution to the problem is through a The two ends of the pipe are clamped by a top clamp; however, even though the flexible live center is used at the end, due to its poor internal stability, there is still a problem that the dimensional accuracy of the central part is not high due to gravity. The problem is that the middle Insufficient support, resulting in weak overall rigidity and stability. The tensioning method of building precast slabs during the pouring process is supported by adjustable horizo...
