Referring to fig. 1-3, an embodiment of the present utility model provides a material tensile mechanical testing apparatus, comprising: the test equipment comprises a test equipment main body 10, a test fixture 20, a positioning piece and a stretching device 30.

In the embodiment of the present utility model, the test apparatus main body 10 may employ a material tensile mechanical testing machine in the related art; the device is provided with a base 101, and two upright post 102 guide rails are oppositely arranged on two sides of the base 101; the test fixture 20 and the stretching device 30 are disposed between the two upright 102 rails.

Specifically, referring to fig. 1 and 2, in the embodiment of the present utility model, a test fixture 20 is provided on a test apparatus body 10. Taking the case shown in fig. 1 and 2 as an example for illustration, the test fixture 20 may be provided on the base 101. In addition, in the embodiment of the present utility model, the test fixture 20 is rotatably connected to the test equipment main body 10.

It should be noted that, in the embodiment of the present utility model, the rotatable connection between the test fixture 20 and the test apparatus main body 10 may specifically refer to: the angle between the test fixture 20 and the test device body 10 is variable. For example, as shown in fig. 1 and 2, the test fixture 20 is maintained in a parallel or nearly parallel state between the whole of fig. 1 and 2 and the base 101 of the test device body 10. In some application scenarios, the test fixture 20 may also be rotated relative to the base 101 of the test apparatus main body 10, so that an angle between the test fixture 20 and the base 101 of the test apparatus main body 10 may be, for example, 30 °, 60 °, 90 °, 120 °, 150 ° or 180 °.

It should be noted that, the numerical values and the numerical ranges related to the embodiments of the present utility model are approximate values, and may have a certain range of errors under the influence of the manufacturing process, and those errors may be considered to be negligible by those skilled in the art.

In this way, after the test specimen 40 (for example, a tape or an adhesive tape) is connected to the test fixture 20, the peel strength of the test specimen 40 can be tested from different angles.

In the embodiment of the present utility model, the sample 40 to be tested may be a tape, an adhesive tape or a coiled material. Of course, in a specific application, the sample 40 to be tested may be other samples that need to be tested for peel strength, and in the embodiment of the present utility model, the sample 40 to be tested is taken as a material tape or an adhesive tape as a specific example.

In a specific implementation, the test fixture 20 may be rotatably connected to the test apparatus body 10 through a rotation shaft. Specifically, the shaft holes may be formed in the test apparatus main body 10 and the side, connected to the test apparatus main body 10, of the test tool fixture 20, and then the connecting members 302, such as a rotation shaft or a pin shaft, may be inserted into the shaft holes, so as to realize the rotational connection between the test tool fixture 20 and the test apparatus main body 10.

Here, referring to fig. 1 and 2 as an example, the side of the test fixture 20 connected to the test apparatus body 10 may be the bottom of the test fixture 20. It will be appreciated that in some examples, the side of the test fixture 20 to which the test device body 10 is attached may specifically be referred to as: the test fixture 20 is connected to the test specimen 40 on the back side or on the opposite side.

In the embodiment of the present utility model, a positioning member (not shown in the drawing) is disposed at the connection position between the test fixture 20 and the test equipment main body 10, and the positioning member is used for positioning the test fixture 20.

Specifically, in the embodiment of the present utility model, when specifically set, the positioning member may be located between the test fixture 20 and the test equipment main body 10.

In some examples, referring to fig. 2 and 3, the rotational positions of the test fixture 20 and the test equipment body 10 may be set at a middle or intermediate position of the test fixture 20 in the length direction. The length direction of the test fixture 20 may be the horizontal direction in fig. 2, or, taking fig. 2 as an example, may refer to the direction shown by the x-axis in fig. 2. At this time, the positioning member may be a pin for defining the rotation angle of the test fixture 20.

Alternatively, in some examples, the positioning members may be telescoping cylinders (e.g., air cylinders, piston cylinders, electric cylinders, etc.) disposed at both ends of the test fixture 20 in the length direction.

It can be appreciated that when the positioning member is a telescopic cylinder provided at both ends of the test fixture 20, the end of the telescopic cylinder may be rotatably connected to the test fixture 20; when the angle of the test fixture 20 is adjusted or regulated, one telescopic cylinder pushes away one side of the test fixture 20, which is opposite to the test equipment main body 10, and the other telescopic cylinder pulls the test fixture 20 towards one side, which is opposite to the test equipment main body 10, so that a certain included angle is formed between the test fixture 20 and the test equipment main body 10. After the required angle is adjusted, the two telescopic cylinders support the test fixture 20, so that the angle of the test fixture is positioned.

In other examples, the rotational positions of the test fixture 20 and the test equipment body 10 may be set at the ends of the test fixture 20 in the longitudinal direction.

That is, in some examples of embodiments of the present utility model, one end of the test fixture 20 is rotatably connected to the test device body 10, while the other end of the test fixture 20 is a movable end that can rotate about a rotation axis away from or toward the test device body 10, specifically away from or toward the base 101 of the test device body 10. In this case, the positioning member may be a spacer provided between the end portion (specifically, the movable end) of the test fixture 20 and the base 101 of the test equipment body 10. For example, the spacer is padded when the angle is required to be adjusted, and the spacer is taken away when the angle is not required to be adjusted. Of course, in some examples, the positioning member may also be a telescopic cylinder as in the previous embodiments.

With continued reference to fig. 1 and 2, in the embodiment of the present utility model, the stretching device 30 is located at one side of the test fixture 20, the stretching device 30 is movably connected to the test apparatus main body 10, and the stretching device 30 is used for stretching the sample 40 to be tested in a direction away from the test fixture 20.

Specifically, in the embodiment of the present utility model, the stretching device 30 may be a telescopic cylinder, a piston cylinder, a linear electric cylinder, or the like. When the test fixture is specifically used, the material belt body of the test sample 40 (such as a material belt or an adhesive tape) can be connected with the stretching device 30, the end part of the material belt is connected with the test fixture 20, and when the stretching device 30 moves, the distance between the stretching device 30 and the test fixture 20 is increased, so that the peeling strength between the material belt and the material belt body is tested.

It should be noted that, referring to fig. 2, in the embodiment of the present utility model, the stretching device 30 may be specifically located on a side of the test fixture 20 facing away from the test apparatus main body 10.

According to the material tensile mechanical test equipment provided by the utility model, the rotatable test fixture 20 is connected to the test equipment main body 10, so that when the glass strength of a material belt is tested or tested, the test fixture 20 can be adjusted or regulated to a required test angle according to the test requirement; then, the test fixture 20 and the test equipment main body 10 are fixed by the positioning piece, namely, kept at a fixed test angle, and the to-be-tested sample 40 (for example, a material belt) is stretched by the stretching device 30, so that the peeling strength of the to-be-tested sample 40 can be tested at the fixed angle; in addition, since the test fixture 20 and the test equipment main body 10 are rotatably connected, the peeling strength of the test sample 40 can be tested under different angles, so that the peeling strength of the test sample 40 can be reflected from different angles, the peeling strength of a material belt can be reflected more comprehensively and accurately, and the accuracy of the peeling strength test of the material belt is improved.

In some examples of embodiments of the present utility model, referring to fig. 3, a test fixture 20 includes: a connection base 201 connected to the test device body 10.

Specifically, in the embodiment of the present utility model, the connection base 201 may be detachably connected to the apparatus body. In some examples, the connection base 201 may be detachably connected to the test device body 10 by a connection fixture such as a screw and nut.

Referring to fig. 4 and 5, in other examples of embodiments of the present utility model, the connection base 201 may be inserted into the test device body 10, and then the connection base 201 is connected to the test device body 10 by a latch.

In the embodiment of the present utility model, the connection base 201 is detachably connected with the test equipment main body 10, so that the test fixture 20 in the embodiment of the present utility model is convenient to connect and detach with the test equipment main body 10, that is, when a test is performed according to different test conditions (for example, for different test objects), different test fixtures 20 may be replaced, thereby improving the application range of the material tensile mechanical test equipment provided by the embodiment of the present utility model.

Referring to fig. 3, in the embodiment of the present utility model, a first sample holding mechanism 202 is rotatably connected to a connection base 201; the positioning member is provided at the junction between the connection base 201 and the first sample holding mechanism 202.

In the embodiment of the present utility model, the first sample holding mechanism 202 is rotatably connected to the connection base 201 by the connection base 201 being connected to the test apparatus main body 10. In this way, the angle of the first sample holding mechanism 202 is conveniently adjusted, and the peel strength of the material strip is conveniently tested at various angles. In addition, the first specimen holding mechanism 202 and the connection base 201 can be mounted to the test device body 10 as separate sub-members, so that the test device body 10 in the related art can be directly utilized, thereby enabling the production cost of the test device body 10 to be saved.

Fig. 6 is an enlarged view of the connection between the first sample holding mechanism and the connection base 201 in the material tensile mechanical testing apparatus according to the embodiment of the present utility model.

Referring to fig. 4 to 6, in the embodiment of the present utility model, a first rotation shaft hole 2011 is formed on the connection base 201, and a second rotation shaft hole 2021 is formed on the first sample clamping mechanism 202; the connection base 201 and the first sample holding mechanism 202 are rotatably connected by a rotation pin (not shown) penetrating through the first rotation shaft hole 2011 and the second rotation shaft hole 2021.

Specifically, in the embodiment of the present utility model, the apertures of the first rotation shaft hole 2011 and the second rotation shaft hole 2021 may be the same or similar. In some examples, the swivel pin may be a cylindrical attachment member such as a screw, bolt, or threaded rod. In other alternative examples, the pivot pin may be a rivet.

In a specific arrangement, as shown in fig. 5, a receiving groove may be formed in a side of the connection base 201 facing the first sample holding mechanism 202, and the first shaft hole may penetrate both side walls of the receiving groove in the radial direction of the connection base 201. The bottom of the first sample holding mechanism 202 may be inserted into the accommodating groove, and connected by passing through the first rotation shaft hole 2011 and the second rotation shaft hole 2021 sequentially through the rotation pin shaft.

In other alternative examples, a receiving groove may be formed at the bottom of the first sample holding mechanism 202, and the connection base 201 may be inserted into the receiving groove.

It will be appreciated that in alternative examples of embodiments of the utility model, the swivel pin may be provided on one of the first sample holding mechanism 202 or the connection base 201. That is, in some possible examples, the swivel pin may be fixed (e.g., integrally formed) with one of the first sample clamping mechanism 202 or the connection base 201. The other of the first sample holding mechanism 202 and the connection base 201 is provided with a rotation shaft hole (for example, the first rotation shaft hole 2011 or the second rotation shaft hole 2021).

To illustrate a specific example, in the embodiment of the present utility model, a rotating shaft may be disposed on one side of the connection base 201 along the radial direction, that is, the rotating shaft protrudes along the radial direction of the connection base 201 and is connected with the side wall of the connection base 201; then, a second rotation shaft hole 2021 is provided in the first sample holding mechanism 202; at the time of installation, the rotation shaft is inserted into the second rotation shaft hole 2021, thereby realizing the rotation connection of the connection base 201 and the first sample holding mechanism 202.

With continued reference to fig. 4-6, in an embodiment of the present utility model, at least one first positioning shaft hole 2012 is provided on one of the connection base 201 and the first sample holding mechanism 202, which is parallel to the rotation pin.

Specifically, referring to fig. 4 and 5, in the embodiment of the present utility model, the first positioning shaft hole 2012 is provided on the connection base 201 as an example. The first positioning shaft hole 2012 penetrates the connection base 201 in the radial direction of the connection base 201. In a specific arrangement, the first positioning shaft hole 2012 may be disposed along the axial direction of the connection base 201 and side by side with the first rotation shaft hole 2011; that is, a line connecting the axis of the first positioning shaft hole 2012 and the axis of the first rotation shaft hole 2011 may be parallel or coincident with the axis of the connection base 201.

Of course, in some examples, the first positioning shaft hole 2012 may be disposed at a position offset from the axis of the connection base 201, that is, a line connecting the axis of the first positioning shaft hole 2012 and the axis of the first rotation shaft hole 2011 may form an angle with the axis of the connection base 201.

It will be appreciated that the first locating shaft hole 2012 is juxtaposed with the pivot pin upon insertion of the pivot pin into the first pivot shaft hole 2011.

In the embodiment of the present utility model, referring to fig. 6, a plurality of second positioning shaft holes 2022 are provided on the other connecting base 201 and the first sample holding mechanism 202 (in the embodiment of the present utility model, the second positioning shaft holes 2022 are provided on the first sample holding mechanism 202 in fig. 6 as an example); the plurality of second positioning shaft holes 2022 are arranged at intervals along the circumferential direction of the rotation pin shaft.

Specifically, as described with reference to fig. 6, in the embodiment of the present utility model, the plurality of second positioning shaft holes 2022 may be specifically arranged along the circumferential direction of the second rotation shaft hole 2021. That is, the plurality of second positioning shaft holes 2022 are arranged in an arc shape, and the circle center of the arc of the plurality of second positioning shaft holes 2022 arranged in the arc shape is the same as the circle center or the axis of the second rotation shaft hole 2021. Thus, when the first sample holding mechanism 202 rotates around the rotation pin, the plurality of second positioning shaft holes 2022 rotate on the same circular arc, so that the plurality of second positioning shaft holes 2022 are aligned with the first positioning shaft holes 2012 and connected by the positioning members.

Taking the z-axis positive direction of 0 ° as an example in fig. 6 for illustration, the test angles corresponding to the plurality of second positioning shaft holes 2022 rotating counterclockwise along the z-axis positive direction may be 0 °, 30 °, 60 °, 90 °, 120 °, 150 °, 180 °, etc., respectively.

It should be understood that, in the embodiment of the present utility model, the above-mentioned test angles are only shown as specific examples, and are not limited to specific test angles.

In particular use, the first sample holder 202 may be rotated and the first sample holder 202 rotated to an angle, such as 90, at which testing is desired; then, the positioning member is sequentially inserted into the first positioning shaft hole 2012 and the second positioning shaft hole 2022, and at this time, the first sample clamping mechanism 202 and the connection base 201 are connected by two connection points, namely, a rotation shaft pin and the positioning member.
