When a mechanical test is carried out on the T-shaped welding test piece, the bending assist device can be used for guaranteeing the upward bending angles of a horizontal plate body of the T-shaped welding test piece to be consistent, so that the accuracy of bending crack detection of the test piece can be guaranteed.
Description
Technical field
The present invention relates to a kind of crooked servicing unit of mechanical test machine, be meant the crooked servicing unit of a kind of T shape welding piece testing machine especially.
Background technology
T shape welding piece is that the end with a plate body is welded on the surface of another piece plate body and constitutes, and its shape becomes T shape, and weld seam also is referred to as T shape weld seam.After the two boards material done T shape welding, need carry out Experiments of Machanics to T shape weldment, the cracking resistance of test T shape weld seam, whether up to standard, mainly be on the mechanical test machine, to accomplish to the test of T shape welding piece if detecting T shape weld seam.
The mechanical test machine of being known at present comprises a groove and pressure head; The vertical plate body of T shape welding piece is vertically put in the groove; The horizontal plate body of T shape welding piece is across groove, and the center that presses down horizontal plate body through pressure head is bent upwards it, and the back of bending is detected T shape weld seam.Yet; Because when vertically plate body and horizontal plate body welded, the tensile strength that is positioned at the weld seam of vertical plate body both sides can not be identical, and; Meeting move left and right when vertically plate body is placed in the groove; Thereby it is inconsistent to be positioned at angle curved on the horizontal plate body of vertical plate body both sides, cause a side angle weld seam angle of bend not enough, and opposite side is because curved transitions toe of weld cracking.The limitation of equipment performance causes the bend specimen outward appearance asymmetric, thereby causes test specimen bending crack testing result inaccurate.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of T shape welding piece testing machine crooked servicing unit; When T shape welding piece is done mechanical test; This bending servicing unit can guarantee that angle curved on the horizontal plate body of T shape welding piece is consistent, guarantees the accuracy that the test specimen bending crack detects.
For solving the problems of the technologies described above; Technical scheme of the present invention is: the crooked servicing unit of a kind of T shape welding piece testing machine; Comprise bearing, said bearing is provided with vertical groove, vertically is slidingly fitted with slide in the said groove; Said slide is provided with the vertical mounting groove of the vertical plate body that is used to place T shape weldment, and said slide is provided with the clamp device that is used to clamp vertical plate body.
As a kind of preferred scheme, described clamp device comprises that activity is positioned over the clamp in the vertical mounting groove, and said slide is provided with the clamping screw of pushing tow clamp.
As a kind of preferred scheme, upper end, said groove two side is arranged with backing roll.
After having adopted technique scheme, effect of the present invention is: because the crooked servicing unit of a kind of T shape welding piece testing machine comprises bearing; Said bearing is provided with vertical groove, vertically is slidingly fitted with slide in the said groove, and said slide is provided with the vertical mounting groove of the vertical plate body that is used to place T shape weldment; Said slide is provided with the clamp device that is used to clamp vertical plate body, therefore, and when on testing machine, testing; The vertical plate body of T shape welding piece is placed in the vertical mounting groove and through clamp device clamps, vertical plate body is on the center plane of symmetry of groove, the pressure head of testing machine is a pressure roller; The vertical plane of symmetry of this pressure roller and the center plane of symmetry of groove are the same plane of symmetry; Like this, can accurately be pressed in the centre of horizontal plate body when pressure roller presses down, and vertically plate body can move left and right; Bending angle is consistent on the horizontal plate body, guarantees the accuracy that the test specimen bending crack detects.

Embodiment
Through specific embodiment the present invention is made further detailed description below.
Extremely shown in Figure 3 like Fig. 1; The crooked servicing unit of a kind of T shape welding piece testing machine comprises bearing 1, and said bearing 1 is provided with vertical groove 2; Vertically be slidingly fitted with slide 3 in the said groove 2; Sliding type between this slide 3 and the groove 2 can be slidingly installed in the present known technology wherein a kind of, and as on groove 2 madial walls, being provided with chute, slide 3 is slidingly mounted on to form in the chute and is slidingly installed; Or be that both sides are provided with chute on slide 3, being provided with protruding slide rail in the groove 2, chute vertically is enclosed within on the slide rail.Said slide 3 is provided with the vertical mounting groove of the vertical plate body 62 that is used to place T shape weldment, and said slide 3 is provided with the clamp device that is used to clamp vertical plate body 62.
Concrete; Described clamp device comprises that activity is positioned over the clamp 4 in the vertical mounting groove; Said slide 3 is provided with the clamping screw 5 of pushing tow clamp 4, and a side and end that said clamping screw 5 laterally is installed in slide 3 head on clamp 4, makes clamp 4 clamp vertical plate body 62 through turning clamping screw 5; Make the vertical plane of symmetry of vertical plate body 62, the vertical plane of symmetry of groove 2 and the vertical plane of symmetry coplane of testing machine pressure head 8; Certainly, clamp device can also be other structure, clamps like wedge clamping block 4 and waits other known clamping modes.
Upper end, said groove 2 two sides is arranged with backing roll 7.When detecting, horizontal plate body 61 is placed on the backing roll 7, transfers sliding friction to rolling friction, thereby makes horizontal plate body 61 bendings smooth and easy.
During concrete operations, at first the vertical plate body 62 with T shape welding piece 6 is inserted in the vertical mounting groove, and horizontal plate body 61 across groove 2 and place backing roll on; Tighten clamping screw 5 and make clamp 4 clamp vertical plate body 62, testing machine pressure head 8 presses down, and slide 3 is stressed to lower slider; Horizontal plate body 61 is bent upwards; Because vertically plate body 62 is fixing can't horizontal jitter, guarantees that 62 of vertical plate bodys slide straight down, horizontal plate body 61 stressed evenly; Last bending angle is consistent, thereby guarantees that test specimen bending crack detection architecture is accurate.
