Abstract
Description
Technical Field
[0001] The present application relates to the technical field of auxiliary tooling for tensile testing machines, and specifically discloses an auxiliary tooling for tensile testing machines. Background Art
[0002] Tensile testing machine is a test equipment commonly used to measure product characteristics such as compression, insertion and extraction force, and sliding resistance.
[0003] As product requirements continue to increase, experiments on product characteristics also need to be more precise in order to ensure the accuracy of the output measurement results;
[0004] The previous tensile testing machine equipment used a cylinder plus a pin for positioning, which led to a series of problems such as the tooling being misaligned and uneven, resulting in deviations in the test results;
[0005] For example, as the instruction manual Figure 2 As shown, the conventional tensile testing machine has two fixtures, namely a first fixture and a second fixture. The first fixture and the second fixture are fixed on the same central axis. The workpiece to be tested is set between the first fixture and the second fixture. At this time, the first fixture and the second fixture are started, and the first fixture and the second fixture generate opposite tensile forces, thereby testing the tensile force of the workpiece;
[0006] The problem also arises here: First, it should be made clear that not all workpieces are regular workpieces. There are irregular workpieces. For irregular workpieces, if the center line of the irregular workpiece is installed between the first fixture and the second fixture according to the traditional rules, it will cause the center axis between the first fixture and the second fixture to be not on the same straight line with the center line of the irregular workpiece. At this time, the conventional operation is to offset the installation of the workpiece, forcing the center axis between the first fixture and the second fixture to be on the same straight line with the center line of the irregular workpiece;
[0007] At this point the following problems will arise:
[0008] In order to adapt to the central axis of the first fixture and the second fixture, the center line of the workpiece is offset too seriously, and the first fixture and the second fixture are directly detached during the tensile process, resulting in failure of the tensile test. In view of this, the inventors have invented an auxiliary tooling for a tensile machine. Summary of the invention
[0009] The purpose of the invention is to solve the problem that the traditional heterogeneous workpiece is inconvenient to use on a tensile machine.
[0010] In order to achieve the above object, the present invention provides the following basic scheme:
[0011] An auxiliary tooling for a tensile machine, comprising a first fixture and a second fixture arranged on the tensile machine, a plurality of connecting columns arranged with the first fixture as the center, a threaded section arranged at the end of the connecting column, a plane plate sleeved on the threaded section, and a thread group threadedly connected to the threaded section for fixing the position of the plane plate; the plane plate is provided with a positioning assembly, and the positioning assembly is used in conjunction with the second fixture;
[0012] The plane plate is provided with a horizontal groove and a vertical groove, the horizontal groove is provided with a left-right direction adjustment component, the vertical groove is provided with a front-back direction adjustment component, the plane plate is provided with a connecting block, the first clamp is installed on the connecting block, and the first clamp can realize front-back and left-right direction movement under the action of the left-right direction adjustment component and the front-back direction adjustment component.
[0013] The principles and effects of this basic solution are:
[0014] 1. Compared with the prior art, the device has a simple structure and an ingenious design. The device solves the problem that it is inconvenient to use traditional heterogeneous workpieces on a tensile testing machine. The main design core is that since the center line of the heterogeneous workpiece is not consistent with the center line of the traditional regular workpiece and the center axis on the first fixture and the second fixture, there is a situation where the center line of the heterogeneous workpiece is offset from the center axis. The offset will cause distortion of the tensile test data. Therefore, a tensile testing machine auxiliary tooling is set to overcome the problem of inconsistency between the center line and the center axis, thereby ensuring the authenticity of the test data.
[0015] 2. Compared with the prior art, the present device is provided with a flatness adjustment component, which is used to make the installation surface of the workpiece consistent with the reference surface of the tensile machine, ensuring that one surface of the workpiece to be tested and the reference surface of the tensile machine are on the same straight line, which is conducive to keeping the subsequent workpiece consistent with the central axis.
[0016] 3. Compared with the prior art, the device is provided with a front-to-back direction adjustment component, which is used to reasonably adjust the position of the workpiece, first ensuring that the workpiece will not fall. On the basis of ensuring that the workpiece will not fall, the center line of the workpiece can be adjusted so that the center line of the workpiece is consistent with the central axis, thereby ensuring the authenticity of the test data.
[0017] 4. Compared with the prior art, the present device is provided with a left-right adjustment component, which is used to reasonably adjust the position of the workpiece, first ensuring that the workpiece will not fall. On the basis of ensuring that the workpiece will not fall, the center line of the workpiece can be adjusted so that the center line of the workpiece is consistent with the central axis, thereby ensuring the authenticity of the test data.
[0018] Furthermore, both the first clamp and the second clamp are slot-type clamps, and the second clamp is detachably connected to the tension output end of the tensile testing machine. A laser emitter is provided at the center of the second clamp, and the alignment component includes an alignment column and a laser receiving target arranged inside the alignment column, and the laser emitter and the laser receiving target are electrically connected.
[0019] Furthermore, the thread group includes a first nut and a second nut, both of which are threadedly connected to the thread segment, and the flatness of the plane plate is changed by the relative positions of the first nut and the second nut on the thread segment.
[0020] Furthermore, a level is provided on the plane plate.
[0021] Furthermore, the horizontal groove and the vertical groove are penetrated, and the left and right direction adjustment component includes friction blocks fixed to the connecting block near the two sides of the horizontal groove and a slot opened on the vertical groove. The bottom of the connecting block is symmetrically fixed with an insertion block, and the insertion block is slidably connected to the slot.
[0022] Furthermore, the first clamp is fixedly connected to the central axis of the connecting block.
[0023] Furthermore, the front-rear direction adjustment assembly includes a mounting hole and a connecting screw opened on the vertical slot, and the connecting screw passes through the mounting hole and is connected to the connecting block. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0029] The figure marks in the drawings of the specification include: second fixture 1, first fixture 2, heterogeneous workpiece 3, reference plane 4, connecting column 5, threaded segment 6, alignment column 8, plane plate 9, transverse groove 10, vertical groove 11, slot 12, connecting block 13, connecting plate 14, laser receiving target 16, laser emitter 17, central axis 18, thread group 19, mounting hole 20.
[0030] Implementation example Figure 1 , Figure 2 and Figure 3 As shown:
[0031] A tensile machine auxiliary tooling, comprising a first clamp 2 and a second clamp 1 arranged on the tensile machine,
[0032] Regarding the first clamp 2 and the second clamp 1: Figure 1 and Figure 2 and Figure 3 As shown, a first clamp 2 and a second clamp 1 of a slot type are used. The types and materials of the first clamp 2 and the second clamp 1 are set according to actual conditions and are not limited to the slot type clamps. Secondly, the conventional first clamp 2 and the second clamp 1 are initially set to be double fixed, that is, the first clamp 2 and the second clamp 1 do not move left and right, and only the change in the relative distance between the first clamp 2 and the second clamp 1 is used to clamp the workpiece, that is, the central axis 18 of the first clamp 2 and the second clamp 1 is on a straight line at the beginning of setting;
[0033] This tensile testing machine can be used to support regular workpieces, because the three centers of the regular workpieces are unified, and it is easy to make the three centers of the regular workpiece and the central axis 18 of the first clamp 2 and the second clamp 1 on the same straight line, but it is not suitable for special-shaped workpieces, because the three centers of special-shaped workpieces are not unified. Therefore, this case is based on this improvement, and further solves the problem of the inconvenience of using traditional special-shaped workpieces 3 on the tensile testing machine.
[0034] First, the first fixture 2 is still fixed, with a plurality of connecting columns 5 arranged with the first fixture 2 as the center, a threaded section 6 arranged at the end of the connecting column 5, a plane plate 9 sleeved on the threaded section 6, and a thread group 19 threadedly connected to the threaded section 6 for fixing the position of the plane plate 9;
[0035] The second fixture 1 is detachably connected to the tension output end of the tensile machine, a laser emitter 17 is provided at the center of the second fixture 1, the alignment component includes an alignment column 8 and a laser receiving target 16 arranged inside the alignment column 8, the laser emitter 17 and the laser receiving target 16 are electrically connected, the flat plate 9 is provided with an alignment component, and the alignment component is used in conjunction with the second fixture 1;
[0036] Specifically: the second fixture 1 is set to be detachably connected, and then the position of the second fixture 1 is first determined, and the first fixture 2 is used as a reference point, and the laser emitter 17 and the laser receiving target 16 are electrically connected to achieve the position of the second fixture 1, so as to achieve that the central axis 18 of the first fixture 2 and the second fixture 1 are on the same straight line;
[0037] The benefits are:
[0038] The laser path of the laser emitter 17 is the path of the central axis 18, which can be seen by the naked eye. Secondly, the center line of the plane plate 9 and the central axis 18 are on the same straight line;
[0039] Specifically: the thread group 19 includes a first nut and a second nut, both of which are threadedly connected to the thread segment 6. The flatness of the plane plate 9 is changed by the relative positions of the first nut and the second nut on the thread segment 6. A level is provided on the plane plate 9.
[0040] Specifically: since the alignment column 8 is arranged on the reference surface 4 of the original tensile machine, it is necessary to ensure that the plane plate 9 is kept flush with the reference surface 4 of the original tensile machine. Because a level gauge is provided, the plane plate 9 is kept flush with the reference surface 4 of the original tensile machine by changing the relative positions of the first nut and the second nut on the threaded section 6;
[0041] When the plane plate 9 is kept flush, all objects mounted on the plane plate 9 are kept flush with the reference surface 4 of the original tensile machine;
[0042] The flat plate 9 is provided with a transverse groove 10 and a vertical groove 11, the transverse groove 10 is provided with a left-right direction adjustment component, the vertical groove 11 is provided with a front-back direction adjustment component, the flat plate 9 is provided with a connecting block 13, the first clamp 2 is installed on the connecting block 13, and the first clamp 2 can move in the front-back and left-right directions under the action of the left-right direction adjustment component and the front-back direction adjustment component.
[0043] Specifically: the horizontal groove 10 and the vertical groove 11 are penetrated, the left and right direction adjustment component includes friction blocks fixedly connected to the connecting block 13 near the two sides of the horizontal groove 10 and a slot 12 opened on the vertical groove 11, the bottom of the connecting block 13 is symmetrically fixed with an insertion block, the insertion block is slidably connected to the slot 12, the first clamp 2 is fixed on the central axis 18 of the connecting block 13, the front and rear direction adjustment component includes a mounting hole 20 and a connecting screw opened on the vertical groove 11, and the connecting screw passes through the mounting hole 20 and is connected to the connecting block 13.
[0044] Regarding the left-right direction adjustment component: the connecting block 13 itself slides left-right in the transverse groove 10, and since the insertion block is slidably connected with the slot 12, the insertion block slides left-right in the slot 12;
[0045] Regarding the front-to-back direction adjustment component: when the insertion block slides left and right in the slot 12, a margin in the front-to-back direction is left, so that the insertion block can move forward and backward in the slot 12. When it is moved into place, the connecting screw passes through the mounting hole 20 and is connected to the connecting block 13 to fix the position of the connecting block 13. When the position of the connecting block 13 is fixed, the position of the entire first clamp 2 is fixed;
[0046] The following is an example of our company's special-shaped workpieces:
[0047] The first step is to process the special-shaped workpiece according to the drawing, and then enter the tensile test verification stage. First, find the center of the special-shaped workpiece with the drawing, and use a marker to mark it, which becomes the center line;
[0048] Step 2: If you follow Figure 2 and Figure 3 As shown, after installing the device, reasonably adjust the positions of the front-rear direction adjustment components and the left-right direction adjustment components. After the adjustment is completed, use the connecting screws to fix the connecting block 13. At this point, the positions of the front-rear direction adjustment components and the left-right direction adjustment components are fixed;
[0049] Step 3: Use the front and rear adjustment components and the left and right adjustment components:
[0050] The main thing is to look at the center line of the special-shaped workpiece. Traditionally, the center line of the special-shaped workpiece is forced to be close to the central axis 18 emitted by the laser emitter 17, which puts a lot of pressure on the first clamp 2 and the second clamp 1. In many cases, the first clamp 2 and the second clamp 1 cannot be used at all. Therefore, a front-to-back direction adjustment component and a left-to-right direction adjustment component are set. The front-to-back direction adjustment component and the left-to-right direction adjustment component are used to change the position of the workpiece, thereby changing the center line of the workpiece, so that the center line of the special-shaped workpiece is no longer forced to be close to the central axis 18 emitted by the laser emitter 17, and it is relatively smooth;
[0051] Traditionally, the center line of the special-shaped workpiece is forced to approach the center axis 18 emitted by the laser emitter 17, which puts great pressure on the first fixture 2 and the second fixture 1:
[0052] This is because conventionally there are only the first clamp 2 and the second clamp 1, but the center line of the special-shaped workpiece may be biased to the left or right. Since the first clamp 2 and the second clamp 1 will not move, the special-shaped workpiece can only be forced to lean to the left or right, and then the first clamp 2 and the second clamp 1 are used. In the process of using the first clamp 2 and the second clamp 1 again, there will be unstable holding, because the special-shaped workpiece forced to lean to the left or right will reduce the clamping part, which in turn makes the first clamp 2 and the second clamp 1 under great pressure.
[0053] The device solves the problem that the traditional heterogeneous workpiece 3 is inconvenient to use on the tensile machine.
[0054] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
