Detailed implementation manner

[0025] The following further describes the present utility model in conjunction with embodiments. The described embodiments are only a part of the embodiments of the present utility model, not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-4 As shown, this embodiment discloses a peeling fixture for a material testing machine, including an upper telescopic seat 101, a lower support seat 103, a support plate 104, a slide plate 105 and a pulling assembly. The upper telescopic seat 101 is used to be suspended on a plane, and the upper telescopic seat 101 is used to fix one end of the material to be tested 102 and pull the material to be tested 102; the lower support seat 103 is used to be installed on a plane; the support plate 104 is used to be installed on the lower support seat 103; the slide plate 105 is used to fit on the support plate 104 and slide on the support plate 104, and the other end of the material to be tested 102 is used to be bonded to the slide plate 105; the pulling assembly is installed on the support plate 104, and the pulling assembly is used to pull the slide plate 105;

[0027] Among them, the pulling assembly includes an extension plate 106, a hinge seat 107, a fixed pulley 108 and a pulling rope 109. The extension plate 106 is arranged at the tail of the support plate 104, the hinge seat 107 is installed on the extension plate 106, the fixed pulley 108 is rotatably installed on the hinge seat 107, one end of the pulling rope 109 is used to be connected to the slide plate 105, and the other end passes around the fixed pulley 108 and is connected to the telescopic assembly, and the telescopic assembly is used to pull the pulling rope 109;

[0028] The utility model mainly includes an upper telescopic seat 101, a lower support seat 103, a support plate 104, a sliding plate 105 and a pulling component. During actual use, the staff installs the sliding plate 105 adhered with the material to be tested 102 on the support plate 104, then installs the support plate 104 on the lower support seat 103, and then pulls up one end of the material to be tested 102 and installs it on the upper telescopic seat 101. At this time, the upper telescopic seat 101 and the material to be tested 102 form a 90° angle. Then, both ends of the pulling rope 109 are respectively installed on the telescopic component and the sliding plate 105. When it is necessary to detect the peeling strength of the material to be tested 102, the staff controls the telescopic component and the upper telescopic seat 101 to contract at the same speed and pulling force and change the used force multiple times. At this time, the upper telescopic seat 101 pulls the material to be tested 102 upward. At the same time, the pulling rope 109 pulls the sliding plate 105 around the fixed pulley 108. At this time, the sliding plate 105 closely adheres to the support plate 104 and moves in the direction of the pulling rope 109. Since the material to be tested 102 is clamped by the upper telescopic seat 101, when the upper telescopic seat 101 and the telescopic component are pulled at the same pulling force and speed and the sliding plate 105 is pulled out with different forces multiple times, it is ensured that the material to be tested 102 always maintains a 90° angle with the upper telescopic seat 101 during the peeling strength test. Furthermore, the peeling strength of the material to be tested 102 can be tested. The advantage of such a setting is to test the peeling strength of the material to be tested 102 by pulling the sliding plate 105. The upper telescopic seat 101 and the material to be tested 102 always maintain a 90° angle without using a roller to maintain the angle between the material to be tested 102 and the upper telescopic seat 101, saving the use cost and manufacturing cost.

[0029] As an optional implementation manner, in this embodiment, the telescopic component is specifically a press, the upper telescopic seat 101 is a telescopic rod in the prior art, the output end of the press is connected to the pulling rope 109, and the pulling machine is used to pull the pulling rope 109 with different forces. It should be noted that in this embodiment, the press is a prior art, and this embodiment does not involve the improvement of the structure of the press, so it will not be elaborated here one by one.

[0030] In some embodiments, a clamping component is arranged at the bottom of the upper telescopic seat 101, and the clamping component is used to clamp the material to be tested 102.

[0031] During actual use, the main purpose of setting the clamping component is to clamp the material to be tested 102 so that when the sliding plate 105 is pulled out, the material to be tested 102 can be peeled off from the sliding plate 105.

[0032] In some embodiments, the clamping assembly includes a fixed plate 110, a clamping plate 111, a guide rod 112, and a rotating rod 113. A threaded hole is provided on the clamping plate 111, and a thread is provided on the rotating rod 113. The rotating rod 113 is threadedly connected to the threaded hole. The fixed plate 110 is installed at the bottom of the upper telescopic seat 101. There are four guide rods 112, and the four guide rods 112 are installed at the four corners of the fixed plate 110. The clamping plate 111 is slidably installed on the four guide rods 112. The bottom surface of the rotating rod 113 contacts the fixed plate 110 and is rotatably connected to the fixed plate 110.

[0033] During actual use, when it is necessary to clamp the material to be measured 102, the operator rotates the rotating rod 113. After the rotating rod 113 rotates, it is rotatably connected to the fixed plate 110. Due to the existence of the guide rod 112, when the thread on the rotating rod 113 is in threaded engagement with the threaded hole on the clamping plate 111, the clamping plate 111 will slide on the guide rod 112. At this time, the gap between the clamping plate 111 and the fixed plate 110 becomes larger. After the operator places the material to be measured 102 between the clamping plate 111 and the fixed plate 110, the rotating rod 113 is rotated in the reverse direction again, and the clamping plate 111 resets. The clamping plate 111 and the fixed plate 110 clamp the material to be measured 102, completing the fixation of the material to be measured 102.

[0034] In some embodiments, rubber pads 114 are provided on the opposite sides of both the clamping plate 111 and the fixed plate 110.

[0035] During actual use, the purpose of setting the rubber pads 114 is to prevent damage to the material to be measured 102 caused by too small a gap between the clamping plate 111 and the fixed plate 110.

[0036] In some embodiments, a handwheel 115 is provided at the end of the rotating rod 113.

[0037] During actual use, the main function of setting the handwheel 115 is to facilitate the rotation of the rotating rod 113.

[0038] In some embodiments, placing grooves 116 are provided on both sides of the support plate 104. Sliding portions are provided on both sides of the sliding plate 105. A stepped structure is formed between the sliding portions and the sliding plate 105. The sliding portions are used to slide on the placing grooves 116.

[0039] During actual use, the purpose of setting the placing grooves 116 is to facilitate the installation of the sliding plate 105, so that the sliding plate 105 can slide more stably on the support plate 104.

[0040] In some embodiments, pressing plates 117 are provided on the placing grooves 116. The pressing plates 117 are installed on the support plate 104 through a number of wing nuts 118. The pressing plates 117 are used to limit the radial position of the sliding plate 105.

[0041] During the actual use process, the main function of setting the pressing plate 117 is to enable the sliding plate 105 to slide along the supporting plate 104 and limit the radial direction of the sliding plate 105.

[0042] In some embodiments, a connecting plate 119 is fixedly arranged at the bottom of the upper telescopic seat 101, and the fixing plate 110 is installed on the connecting plate 119 through bolts.

[0043] During the actual use process, the main function of the connecting plate 119 is to facilitate the installation between the upper telescopic seat 101 and the fixing plate 110.

[0044] In some embodiments, a rotating groove is arranged on the fixing plate 110, a bearing is arranged inside the rotating groove, and the rotating rod 113 is rotationally connected to the rotating groove through the bearing.

[0045] During the actual use process, the purpose of setting the rotating groove is to facilitate the relative rotation between the rotating rod 113 and the fixing plate 110. The rotating rod 113 and the bearing are in interference fit. The purpose of setting the bearing is to replace the rotation between the rotating rod 113 and the rotating groove through the self-rotation of the inner and outer rings of the bearing, thereby reducing the rotational friction between the rotating rod 113 and the rotating groove and making the service life of the rotating rod 113 longer.
