When the titanium metal sample to be tested is rod-shaped, the rod-shaped sample 400 can be held by hand and one end of the rod-shaped sample 400 is inserted into the upper jig 300, and at this time, the end of the rod-shaped sample 400 is positioned in the middle of the arc-shaped grooves 7 of the two clamp blocks 6. Then, the sliding seat 1 is driven to move upwards by the swivel 3, and the V-shaped cavity and the two first inclined planes 11 move upwards accordingly. At this time, since the clamp block 6 and the annular flange 21 are abutted, the clamp block 6 cannot be carried up, and the two clamp blocks 6 in the V-shaped cavity will approach each other under the action of the first inclined surface 11 and the second inclined surface 61 until the wall surface of the arc-shaped groove 7 is tightly attached to the circumferential surface of the rod-shaped sample 400, so that the clamping of one end of the rod-shaped sample 400 is realized.
Meanwhile, the sliding seat 1 also drives the wedge-shaped block5 to move upwards in the upward moving process. At this time, a part of the rod-shaped sample 400 is also located in the arc-shaped groove 7 of the clamp block 4, and the clamp block 4 cannot move back and forth under the blocking of the rod-shaped sample 400. It will be appreciated that the first and second protrusions cannot move back and forth at this time, and the first and second protrusions will limit the upward movement of the wedge 5, under which the wedge 5 slides to one side in the front-rear direction, thereby avoiding the first and second protrusions. When the wedge block5 located at the front side slides forward, the elastic force between the wedge block5 and the sliding seat 1 increases, and the elastic force acts on the left clamping block 4 through the wedge block5 and forces the clamping block 4 to press against the rod-shaped sample 400 backward. When the wedge block5 located at the rear side slides backward, the elastic force between the wedge block5 and the sliding seat 1 increases, and the elastic force acts on the clamping block 4 at the right side through the wedge block5 and forces the clamping block 4 to press forward against the rod-shaped sample 400. Thus, after the rod-shaped sample 400 is clamped, the rod-shaped sample 400 can not only be subjected to the forces in the left-right direction of the two clamping blocks 6, but also be subjected to the forces in the front-back direction of the two clamping blocks 4, so that the clamping effect of the rod-shaped sample 400 is improved, and the rod-shaped sample 400 can be clamped more firmly. Meanwhile, because the clamping block 4 is used for auxiliary clamping, the clamping force of the clamping block 6 on the rod-shaped sample 400 is not required to be increased all the time, so that the extrusion deformation of the clamping block 6 is reduced, the deeper indentation on the surface of the rod-shaped sample 400 is avoided, in addition, the abrasion of the clamping block 6 in the subsequent tensile test is reduced, and the service life of the clamping block 6 is prolonged.
When one end of the rod-shaped sample 400 is clamped by the clamping block 6 and the clamping block 4, two motors 103 can be started, the two motors 103 drive the two lead screws 102 to rotate, the two lead screws 102 drive the cross beam 200 to move downwards, and the cross beam 200 drives the upper clamp 300 and the rod-shaped sample 400 to move downwards until the other end of the rod-shaped sample 400 is inserted into the lower clamp 300. Thereafter, the lower clamp 300 may be driven to clamp the other end of the rod-shaped sample 400, as in the above process.
Subsequently, the motor 103 drives the cross beam 200 to move upwards, the cross beam 200 performs a tensile test on the rod-shaped sample 400, the load cell 203 measures the tensile strength of the rod-shaped sample 400 and feeds back data to a computer, and the computer displays the data on a screen thereof for recording by staff after analysis and processing.
The sliding seat 1 is provided with a support 12 in one-to-one correspondence with the two wedge blocks 5, the support 12 is provided with sliding holes arranged along the front and rear directions, the sliding holes penetrate through the support 12, the wedge blocks 5 are provided with sliding rods 51 extending along the front and rear directions, the sliding rods 51 slide through the corresponding sliding holes, one ends of the sliding rods 51, deviating from the sliding seat 1, of the sliding rods are provided with round bosses 52, the bosses 52 are coaxial with the sliding rods 51, the diameters of the bosses 52 are larger than those of the sliding rods 51, tension springs 53 are arranged between the bosses 52 and the support 12, the tension springs 53 are sleeved on the outer peripheral sides of the sliding rods 51, and two ends of each tension spring 53 are fixedly connected with the bosses 52 and the support 12 respectively.
When the wedge 5 slides to one side in the front-rear direction, the tension spring 53 is elongated, and simultaneously, the accumulated elastic force acts on the rod-shaped sample 400 again through the wedge 5 and the clamp block 4, thereby achieving auxiliary clamping of the rod-shaped sample 400.
The first projection is provided with a third inclined surface 41 facing downwards, the third inclined surface 41 is attached to the wedge-shaped surface 54 of the corresponding wedge-shaped block 5, the second projection is provided with a fourth inclined surface facing downwards, and the fourth inclined surface is attached to the wedge-shaped surface 54 of the corresponding wedge-shaped block 5.
When the wedge-shaped block 5 moves upwards under the drive of the sliding seat 1, the wedge-shaped surface 54 of the wedge-shaped block 5 is blocked by the third inclined surface 41 or the fourth inclined surface and slides towards the outer side of the sliding seat 1 along the third inclined surface 41 or the fourth inclined surface, so that the first protruding part or the second protruding part of the wedge-shaped block 5 is avoided.
When the two clamping blocks 6 are close to each other, the operator holds the bar-shaped sample 400 by hand to prevent it from falling, which is inconvenient. In order to solve this problem, the present invention also provides embodiment 2.
In embodiment 2, with continued reference to fig. 3 to 8, the holding block 4 is provided with a holding groove extending in the left-right direction, and two opposite ends of the holding grooves are open and opposite ends of the holding grooves are closed in the two holding blocks 4. The clamping plate 42 is slidably matched in the accommodating groove, the clamping plate 42 is connected with the clamping block 4 through an elastic piece, and specifically, the elastic piece comprises two springs 43 which are arranged in the accommodating groove and are spaced apart in the front-back direction, and two ends of each spring 43 are fixedly connected with the clamping plate 42 and the clamping block 4 respectively. The clamping plate 42 is provided with an arc-shaped opening 44, the specific shape of the arc-shaped opening 44 is semicircular, the axis of the arc-shaped opening 44 extends vertically, a chamfer 45 is arranged on the part of the clamping plate 42 for forming the arc-shaped opening 44, and it is understood that the chamfer 45 extends along the arc-shaped trend of the arc-shaped opening 44 and is semicircular.
Normally, the two clamping plates 42 are abutted under the action of the spring 43, and the two arc-shaped openings 44 form a round hole. When the end of the rod-shaped sample 400 is inserted into the clamp 300, the two clamping plates 42 can be pushed away from each other by the chamfer 45, and after the rod-shaped sample 400 is inserted into the clamp 300, the two clamping plates 42 are clamped on the peripheral surface of the rod-shaped sample 400 under the action of the elastic force of the spring 43, so that the clamping plates 42 realize the pre-clamping of the rod-shaped sample 400 through the arc-shaped opening 44. In the process of enabling the two subsequent clamping blocks 6 to be close to each other and clamping the rod-shaped sample 400, the rod-shaped sample 400 does not need to be held by hands, two hands are liberated, and the convenience of the test is improved.
The sheet sample 500 may be deflected when the sheet sample 500 is gripped, and in order to solve this problem, the present invention also provides example 3.
Embodiment 3, with continued reference to fig. 5-11, is based on embodiment 1, wherein the first projection is provided with a vertical first push bar 46 and the second projection is provided with a vertical second push bar 47.
The clamping process of the sheet sample 500 is similar to that of the rod sample 400, except that: when the end of the sheet sample 500 is elastically clamped by the two clamping plates 42 and the sliding frame drives the wedge-shaped block 5 to move upwards, the sheet sample 500 cannot enter the arc-shaped groove 7, so that the sheet sample 500 cannot block the front-back movement of the clamping block 4, in other words, the clamping block 4 can slide freely along the front-back direction. The wedge 5 on the front side pushes the left latch 4 to move backward through the wedge surface 54 and the third inclined surface 41, so that the first push bar 46 moves backward. The wedge 5 at the rear side pushes the latch 4 at the right side forward through the wedge surface 54 and the fourth inclined surface, so that the second push bar 47 moves forward. Therefore, if the sheet sample 500 is in a deflection posture, the two pushing strips can straighten the middle sheet sample 500, and when the sheet sample 500 is righted, the sheet sample 500 can be clamped by the plane of the clamping block 6 positioned in the edge area of the arc-shaped groove 7, so that the sheet sample 500 is clamped. In addition, after the clamping block 4 moves along the front-back direction, the plane of the edge area of the arc-shaped groove 7 in the clamping block 4 is positioned in the middle of the sheet sample 500 and supports the middle of the sheet sample 500, so that the middle of the sheet sample 500 is prevented from collapsing.
The clamping process and the tensile test process of the other side end portion of the sheet-like sample 500 are similar to those described above, and will not be repeated here.
