Embodiment Construction

[0025] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Please combine Figure 1 to Figure 5 As shown, a kind of high-strength bolt hole group space size measuring tool provided by the present invention is connected to the central hole 1 in the hole group at the end of the bar. The measuring tool includes: prism base adapter 2, and its Automatic centering device 3 connected by thread. Since each hole in the high-strength bolt hole group is drilled using a professional CNC drilling machine, it can ensure the relative dimensional accuracy of each hole in the same hole group. Therefore, it is only necessary to measure the spatial size of any hole in the hole group to represent the overall hole. group size.

[0027] Preferably, the prism base adapter 2 is arranged in a long-axis structure, including: a prism joint 21 , a boss 22 and a threaded rod 23 connected sequentially fro...

Abstract

The invention discloses a measuring tool for spatial sizes of high-strength bolt hole groups. The tool is connected to the central hole of an end hole group of a rod member, and comprises a prism baseadapter and an automatic centering device which is in threaded connection with the prism base adapter. The prism base adapter is set to a long-axis structure, and comprises a prism joint, a boss, anda threaded rod which are sequentially connected from top to bottom. A groove is formed in the prism joint. The diameter of the boss is larger than the diameter of the central hole. The length of thethreaded rod is larger than the thickness of the rod member. The automatic centering device is set to a conical frustum structure, and is used for being in threaded connection with the threaded rod. An internal thread hole is formed in the circle center position of the automatic centering device. The diameter of a small round table at the top of the conical frustum structure is smaller than the diameter of the central hole. The diameter of a big round table at the bottom of the conical frustum structure is larger than the diameter of the central hole. The bottom of the conical frustum structure is further set to a polygon. According to the measuring tool for spatial sizes of high-strength bolt hole groups, the operation efficiency is improved, the dependence on the skill level of operatorsis reduced, and the whole air space size can be measured without scribing.

Description

technical field [0001] The present invention relates to the measurement of the space size of hole groups in components, and more specifically, relates to a tool for measuring the space size of high-strength bolt hole groups, which is especially suitable for the high-strength bolt hole groups of each member during the manufacture and installation of truss-type steel structures. The spatial positioning size measurement. Background technique [0002] High-strength bolt connection is a new type of connection developed after rivet connection and welding in steel structure construction, and has now become a common method in steel structure connection applications. Because high-strength bolts are made of high-strength steel, or bolts that require a large pre-tightening force, the fracture of such bolts is mostly brittle fracture. The high-strength bolts used in ultra-high pressure equipment, in order to ensure the sealing of the container, A greater prestress is required. In stee...
