Abstract
The invention discloses a bending test clamp of a welding test piece. The bending test clamp comprises a supporting seat, supporting rollers and a pointer, wherein the supporting rollers are symmetrically arranged along the central axis of the supporting seat; the pointer is arranged at the central axis of the supporting seat; and the position of the axis of the pointer is overlapped with the position of the central axis of the supporting seat. According to the bending test clamp, the pointer is arranged on the central axis of the supporting seat, so that the pointer is aligned with the central axis of the supporting seat and a center line of a weld joint of the welding test piece when the test piece is placed, and the welding test piece is enabled to be positioned just in the middle of the two supporting rollers, thereby improving the accuracy of the bending test of the welding test piece.
Description
Technical field
The present invention relates to a kind of mechanical clamp, particularly a kind of anchor clamps that are used to weld the test piece bending test.
Background technology
Bending test is the test of the mechanical characteristic when measuring metal material and bearing bending load, is one of basic skills of mechanical property of materials test.Existing bending test anchor clamps are to prop up rollers through being bolted on the supporting seat with two, and bending test is placed on the roller, and testing machine applies downward pressure, and test is bent.In order to detect the performance of welded seam, often need butt welded seam to carry out the bending property test, the welding test piece is placed on the roller of bending fixture; Welding test piece weld seam is applied downward pressure; Test piece bends, and when crackle appears in weld seam, stops test; The bending angle of test test piece this moment, the performance of evaluation weld seam.During test, need the position of weld seam be placed on two roller centers, the weld seam center line be overlapped, with the supporting seat axis with warranty test result's precision.Because position and supporting seat that test piece is placed have certain distance, when testing, just confirm the position of weld seam through range estimation in the past, the position that causes welding test piece is failed centering and is influenced stringency of test.
Summary of the invention
The technical matters that the present invention will solve provides a kind of simple in structure, the welding test piece bending test anchor clamps that test accuracy is high.
For solving the problems of the technologies described above; The present invention has adopted a kind of welding test piece bending test anchor clamps, comprise supporting seat and along the supporting seat axis symmetrically arranged roller, also comprise a pointer; Said pointer is installed in place, supporting seat axis, and the pointer axis overlaps with position, supporting seat axis.
Said pointer can be around the tie point rotation of pointer and supporting seat.
The beneficial effect that the present invention has: these welding test piece bending test anchor clamps are through being provided with a pointer on the supporting seat axis; When placing test piece; Pointer is alignd with supporting seat axis and welding test piece weld seam center line; Guarantee to weld the test piece position and hit exactly, thereby improved the precision of welding the test piece bending test at two rollers.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, supporting seat; 2, prop up roller; 3, pointer; 4, supporting seat axis; 5, the tie point of pointer and supporting seat.
Embodiment
As shown in the figure, be a kind of welding test piece bending test anchor clamps, welding test piece bending test anchor clamps; Comprise supporting seat 1 and 4 symmetrically arranged rollers 2 along the supporting seat axis; Also comprise a pointer 3, pointer 3 is installed in 4 places, supporting seat axis, and the pointer axis overlaps with position, supporting seat axis.When welding the bending test of test piece, the both sides that roller 2 is symmetricly set on supporting seat axis 4 are propped up in the position of two rollers 2 of adjustment earlier.To weld test piece and be placed on the roller 2, the position of adjustment welding test piece makes welding test piece weld seam center line and pointer 3 deads in line, and the weld seam that welds test piece this moment just in time is placed on the center of two rollers 2, has guaranteed the precision of welding test piece bending test.
Further this as these bending test anchor clamps advances, and pointer 3 can when welding the bending test of test piece, rotate to pointer 3 position that overlaps with supporting seat axis 4 around tie point 5 rotations of pointer 3 with supporting seat 1; After carrying out common bending test or off-test, can pointer 3 be rotated to supporting seat 1 lateral location, make the bending test anchor clamps in test or handling process, protection pointer 3 is not damaged.
Claims (2)
1. weld test piece bending test anchor clamps; Comprise supporting seat (1) and along supporting seat axis (4) symmetrically arranged rollers (2); It is characterized in that: also comprise a pointer (3); Said pointer (3) is installed in supporting seat axis (4) and locates, and pointer (3) axis overlaps with position, supporting seat axis (4).
2. welding test piece bending test anchor clamps as claimed in claim 1 is characterized in that: said pointer (3) can be around tie point (5) rotation of pointer (3) with supporting seat (1).
