Abstract

The invention discloses a stretching clamp for bolt combination and belongs to a clamp. The combined stretching clamp structurally comprises an upper pull rod, an upper pull bowl, a lower pull rod and a lower pull bowl, wherein the upper pull bowl and the lower pull bowl are respectively in semi-opening structures; one end of the upper pull rod is connected with the upper pull bowl through a thread; one end of the lower pull rod is connected with the lower pull bowl through the thread; a bolt head of to-be-tested bolt combination is placed into the upper pull bowl; and a nut of the to-be-tested bolt combination is placed into the lower pull bowl. Compared with the prior art, the stretching clamp for the bolt combination provided by the invention has the characteristics of small size, material-saving property, no requirement for built-in pull ring, low cost, and the like, so that the stretching clamp for the bolt combination has higher popularization and application values.

Description

The bolt combination stretching clamp

Technical field

The present invention relates to a kind of anchor clamps, especially a kind of bolt combination stretching clamp.

Background technology

For the tension test that solves the specific 8.8 grade high-strength bolt combination of client, traditional bolt tension anchor clamps have the shortcoming of big, the built-in pulling force ring of volume, complicated operation.At present, good solution is not also arranged.

Summary of the invention

Technical assignment of the present invention is a kind of bolt combination stretching clamp to be provided to above-mentioned deficiency of the prior art, and it is little that this bolt combination stretching clamp has a volume, saves material, do not need built-in pulling force ring, the characteristics that reduce cost.

The technical solution adopted for the present invention to solve the technical problems is: it comprises upper connecting rod, upper pulling force bowl, lower link and lower pulling force bowl; Described upper pulling force bowl and lower pulling force bowl are respectively the semi-open type structure; Described upper connecting rod one end links to each other with the upper pulling force bowl through screw thread; Described lower link one end links to each other with the lower pulling force bowl through screw thread, puts into the bolt head of tested bolt combination in the described upper pulling force bowl, puts into the nut of tested bolt combination in the lower pulling force bowl.

Described upper pulling force bowl and lower pulling force bowl are respectively high strength 60Si 2The Mn material is processed.

Bolt combination stretching clamp of the present invention is compared with prior art, and have following outstanding beneficial effect: volume is little, saves material, does not need built-in pulling force ring, reduces cost, and uses convenient mounting and clamping, accurate, quick, and intensity is high, has improved characteristics such as work efficiency.
